Chapter 168: Fishing for Power Generation

Zhang Zhimu led everyone to work for a total of three or four hours from the net to the net, all the time, so busy that the sun was a little westerly. When everyone noticed that there were fish constantly jumping out of the net, the fish collectors soon gradually became too busy. The fish net prepared before is not used at all, the fish that come up are more than a dozen catties of small fish, so they have to use the harpoon to fork the fish one by one, as the net is pulled up, there are more and more fish, and the mouth of the net is almost blocked, there is no way, almost all people are involved in the work of fishing out, and the speed of collecting the net has to be slowed down again and again. Those extra-large fish are no longer something that one person can move, and the big ones are hundreds of catties, such as carp, silver carp, grass carp, large catfish, and so on. The fish soon piled up into a mountain, and the fish glistened golden in the sun, and because it was so cold, the lively fish soon froze into ice mounds. The net was not finished until the sun was about to set. These young and strong dozens of people were tired and spread on the ice. Zhang Zhimu knew that this would not work, and he would get sick after a long time. He shouted: "Get up and put away the nets, and go back to the liquor pipe." ”

Maybe there was liquor waiting for Zhang Zhimu's shouting, so everyone struggled to get up and put the net away. Zhang Zhimu knew that the nets had to be put away, otherwise the nets would freeze together, and he would not be able to work tomorrow.

Back in the greenhouse, it is natural to eat fish. As for stewed fish, steamed fish, and boiled fish soup, Zhang Zhimu didn't care. He picked a big black fish weighing more than 50 catties, picked up the fish skin with a knife, removed the fish bones, and used a sharp knife to slice the fish into thin fillets, and then mixed it with shredded ginger, shredded green onions and white vinegar and a little salt. As a result, this delicious dish of raw fish fillet is the first to be swept away after it is served.

Li Jingzhi complained to Zhang Zhimu and said: "Mr. Zhang, our fish are piled up in a mountain, why don't you mix a little more sashimi." Let everyone eat sweetly. ”

Zhang Zhimu said: "You don't understand, it's because this sashimi is not enough to eat that you think it is particularly delicious." ”

The number of fish in this Xishan bubble is far more than Zhang Zhimu imagined. Early the next morning, Zhang Zhimu instructed everyone to load 20 horses full of fish and climb the plow, and let them transport them back to the kiln gang first. Zhang Zhimu asked Li Jing to lead the team back to Yaogang, tell Lu Chengxiang about the situation here, and ask him to send more chariots and horses to transport fish. After sending Li Jing away, Zhang Zhimu organized everyone to change positions and start to go to the net again.

With the experience of the last time, it was much easier to get off the net this time.

When the net was about to be raised, the brigade of the kiln gang arrived. This time, several giants from Yaogang came to join in the fun, and even Chen Yufeng followed, not to mention Yan Boju, Lu Chengxiang, Li Mao and others. They came with a long caravan of camels and twenty horses to climb the plough, and more than 200 people came, and brought some materials for building sheds. Of course, I brought a lot of food.

Lu Chengxiang said: "The carriage of the brigade was left at the end of the Xiaoling River, and it was impossible to pass through the place where it was fast forward to the lake area, because there was a steep slope there, and the snow was too thick to pass. Li Yunhe was leading people at home to prepare to rebuild another fifty horses and plows. ”

Zhang Zhimu said: "If you come up like this, I think there are at least 10,000 stone fish. It's enough for us to get around for a while. ”

Lu Chengxiang said: "This time Mr. Huang should be happy, her farm no longer has to worry about feed." ”

Zhang Zhimu said: "There are enough people to eat for a while. After going back, you should pick some moderate size and put them in the cold storage on the north side of the kiln. There are a few places in the cold storage, and we have to put some big ice cubes in them. Then close the door tightly, so that the fish will not melt in the summer. ”

Zhang Zhimu asked Chen Yufeng: "You just got married, why did you come, there are still guests waiting for you to entertain at home." ”

Chen Yufeng said with a smile: "I just don't feel at ease to come and take a look, and I will follow the plow to carry the fish back in a while." ”

Zhang Zhimu knew that Chen Yufeng had no choice, otherwise he would definitely stay and have a good time with the big guys. From this, it can be seen that the fish that Li Jing brought back must have caused a sensation in Yaogang.

Chen Yufeng watched the fish net for a while, and before it was completely finished, he left with the horse climbing plough and the camel brigade. The funny thing is that some camels can only carry two fish on one side. Because the fish are so big. The horse plough is responsible for transporting the fish to the side of the wagon, loading it on the cart, and then returning to load the fish. The carriage can be transported back to Yaogang along the surface of the Xiaoling River.

Originally, Zhang Zhimu was going to stop after the second net, but Yan Boju's people didn't do it when they came, so they had to wait a day before going to the next net. As a result, the fish caught were transported for several days. Zhang Zhimu and others are also rare to have such a leisure time, these few nights, they have not eaten less fish and drunk less wine.

The happiest is Li Mao, who has been in the south for a long time, and has mastered a lot of fish practices, so he keeps showing his hands a few times. But Zhang Zhimu's iced sashimi is the most popular among everyone. The live fish in the wild is so delicious.

In the past two days on the ice, everyone slept together, and Zhang Zhimu and Li Mao had the opportunity to have a few conversations. brought the relationship between the two one step closer. Zhang Zhimu felt more and more that Li Mao was a rare talent. This person has a deep mind, a profound view of problems, an open mind, an unassuming person, and a view of the overall situation. This is Zhang Zhimu's evaluation of Li Mao.

After the fish were all shipped, Zhang Zhimu asked everyone to start chiseling the surface of the lake, chiseling the ice into a foot wide and two feet long, and then transporting it back to the kiln. Everyone wondered, what Zhang Zongyun was doing with all this ice. Zhang Zhimu, who had just transported the ice and fish back to Yaogang, was not allowed to enter the cold storage, because Zhang Zhimu knew that the ice and water in the lake had been in contact with the temperature of about zero degrees, and the ice could be frozen to at least minus 20 degrees when put outside, and the fish had to be frozen thoroughly.

On the way back to Yaogang, when Zhang Zhimu saw the horse-drawn plow, he suddenly thought of the skis in his previous life. He said to Li Jing: "Li Jing, I will give you a task, and when you go back, I will ask Li Yunhe to help you make some skis, and you have to practice them first." ”

Li Jing asked, "What is a snowboard?" ”

Zhang Zhimu said: "Your two feet are like a horse climbing a plow, each foot steps on a ski, and then you walk with two sticks." I'll teach you how to ski then. "In his previous life, although Zhang Zhimu was not very good at skiing, there was no problem with rowing away. Zhang Zhimu knew that if his soldiers mastered the skiing skills, then in winter, they would be a fast and mobile army, and when the heavy snow blocked the horses and could not walk, it would be an opportunity for skiers. When you go back, be sure to get your skis out as soon as possible.

Li Mao, who was sitting on the same climbing plow, had already condensed a lot of hoarfrost on his fur hat, and then interjected and asked: "Mr. Zhang, you are moving everyone to smash the ice and fish, won't you just let us drink fish soup?"

Zhang Zhimu admired Li Mao's sober mind very much, and said: "There will be more and more people in our kiln, this place is not suitable for a large number of people, it is necessary to consider carefully, if everything needs to be transported, it will be dangerous." We found a large number of fish resources in Xishan Baozi this time, which can not only solve the problem of people eating fish in the future, but also solve the source of feed for the aquaculture industry. Even if the processed fish oil is very good, it is also a good chemical raw material. And I found that there are many such lakes in Shanxi, which are all available resources. This time we just tested our fishing methods, and it seems to be successful. ”

Li Mao listened to Zhang Zhimu's words, that is, he seemed to understand whether he understood or not, and like all other people, he was full of doubts about Zhang Zhimu, and couldn't help asking: "Mr. Zhang, how did you come up with such a magical way of fishing?" ”

This made Zhang Zhimu a little embarrassed, and it was impossible to tell him that he had watched it on TV in his previous life, and he had to make up a story if he had no choice, saying: "When I saw people weaving fishing nets in the south, I asked them, why don't your fishing nets be woven into a net pocket?" People said it was going to be made into a seine net. So I thought, back in Shanxi, let's make a fence under the ice, why not. ”

Li Mao still didn't understand, and asked, "Then how did you know that you could catch so many fish at once in winter?" ”

Seeing Li Mao's questioning, Zhang Zhimu had no choice but to say: "I only know that when the weather is cold, the fish will run to the bottom of the deep water, because the temperature there is a little higher, and the fish will be gathered together, and I didn't expect to catch so many fish at once." ”

Back at the kiln, Zhang Zhimu looked at it and felt that it was a lot of fun this time, and the fish transported back from Xishan Baozi were like mountains, filling the school's playground. People who were okay were all around and pointing and watching.

As soon as Zhang Zhimu entered the office, Huang Yukun came over and asked Zhang Zhimu: "Why did you get so many fish back at once, and you won't be able to eat them until next year?" ”

Zhang Zhimu said: "You can pick some good ones and send them to cold storage." Pick some more to make fishmeal, and the raw materials for your farm will solve a large part. Feeding these things to chickens and ducks can lay more eggs. Remember to keep the fish oil from the processed fishmeal. ”

"How is fishmeal processed?" Huang Yukun asked.

When Zhang Zhimu heard this, he had something else and said, "When I have time, I'll teach you." It is not difficult to make fishmeal. You have to organize people to get out the fish heads, fish bones, fish intestines, fish stomachs, etc., which can be used to process fishmeal, don't waste it. ”

As soon as Huang Yukun went out, Yang Yulin came in, pointed to a pile of things in the house and said, "Li Yunhe has already sent what you want, and the three people you want have also picked for you." ”

Zhang Zhimu hurriedly said: "Great, Li Yunhe is very efficient." ”

Li Yunhe sent Zhang Zhimu to make the accessories of the generator, because there is no rectifier device yet, so for the convenience of application, Zhang Zhimu decided to make the DC generator first. DC generators are much more complex than alternators, except for some special occasions in the previous life, there are few generators, because with a very simple structure of alternators, it is easy to send out alternating current can be turned into direct current with rectifier devices.

In order to generate electricity, Zhang Zhimu asked Li Yunhe to send three people to him, and the requirements were outstanding cultural and academic achievements and special brains. Zhang Zhimu also stated his interests to Lu Bingyi and asked him to send a disciple to participate in the power generation work.

After Zhang Zhimu asked Yang Yulin to find the three people and Lu Bingyi's disciples, he asked for their names, and the person in charge of the person sent by Li Yunhe was called Li Di, and Lu Bingyi's student was called Yang Chang. Zhang Zhimu said to them: "I brought you here to do a meaningful job, and the importance of this work cannot be overstated. If this succeeds, our entire way of life and work will be completely affected. ”

Then, Zhang Zhimu combined with the physical objects sent by Li Yunhe, and briefly introduced the major components of the DC generator. Tell them:

The DC motor is structurally divided into two parts: static and rotating, the static part is called the stator and the rotating part is called the rotor.

The stator part of the DC motor includes a base, a main magnetic pole, a commutation pole, an end cap, a bearing, and a brush device; The rotor section includes the armature core, armature windings, commutator, fan, and shaft.

Zhang Zhimu said that these four people remembered at the same time.

Zhang Zhimu said: "Our task today is to wind the coil, first the main pole coil, and then the rotor coil. Finally, we put all these devices together. ”

Someone asked: "Mr. Zhang, can you tell us why this thing can send electricity, and what is electricity like?" What is the use of electricity? ”

Zhang Zhimu said: "If I can explain it to you theoretically, it will take a lot of time. You do what I say, and when you have an intuitive impression, we are slowly studying the theoretical problems. Zhang Zhimu thought that if he explained this problem theoretically, he could write a children's book. How can I explain it clearly in a few words, but this thing, after getting started with an intuitive experience, many questions are easy to understand. This is also called "practice to know, practice to know." ”

This motor Zhang Zhimu was designed according to a small motor of 100 watts, but it was designed according to the size of the motor seen in the previous life without calculation. Because it is a small motor, the commutation pole is canceled, so that the structure is simpler, there are four main poles in the stator, that is, two pairs of main poles, the main pole is made of a millimeter thick steel sheet, and the silicon steel sheet is used to make a sixteen-groove rotor. The copper wires are also insulated by Zhang Zhimu himself with tung oil. The insulating paper between the copper wire and the rotor is also made by Zhang Zhimu himself, and the paper is soaked in tung oil and taken out to dry. For the sake of simplicity, the excitation method of this DC motor adopts parallel excitation, that is, the excitation end and the output end are connected in parallel.

In fact, the DC motor is more complicated than the AC motor in the commutator and brush part. When welding this part of the line, Zhang Zhimu did it himself, and he didn't dare to be sloppy.

For the driving part, Zhang Zhimu asked Li Yunhe to make a pulley with a large wheel and a small wheel, so that the hand-cranked big wheel could bring the small wheel to a certain speed.

Since in his previous life, Zhang Zhimu had never made a DC motor, but only knew the principle of a DC motor, so it took a lot of energy and time to make and debug this motor. When one person shook the motor, Zhang Zhimu touched the heads of the two output wires together, and when there was a "pop" and a fire, Zhang Zhimu knew that the generator had succeeded. In order to go further and measure the current, Zhang Zhimu connected the ammeter he made to the output of the motor. When the generator was shaken again, the pointer of the ammeter suddenly hit the limit.

Zhang Zhimu knew that his ammeter had not been calibrated well and there was no gear, but this ammeter had detected the existence of current, which was very telling to the problem.

But now Zhang Zhimu is facing another very perplexing problem. In my previous life, I wanted to breathe every day, and I never thought it was a problem, but now it's a big problem. That's the matter of metering current and voltage.

In my previous life, I would take a multimeter and know it at a glance, but now it's a difficult thing. There is no standard for what a volt voltage is or how much a ampere is current. Standards turned out to be so important, Zhang Zhimu sighed.

However, the problem of resistance is easy to solve, I remember in the previous life, sometimes when there was no large current and small resistance value resistance, I used copper wire to wind it myself. Remember that pure copper at a temperature of 20 degrees Celsius, the resistivity is 0.0175 ohms square mm/m. Although the purity of copper is not too high now, the resistance is not too bad, and this accuracy is enough. The difficulty is that none of the voltage and current can be determined, otherwise, one is determined, and the other can be calculated according to Ohm's law.

Zhang Zhimu knew that there was a kind of tourmaline with a current of six milliamperes on the surface, but there was no such means to measure such a tiny current. However, the voltage of the galvanic battery is relatively constant, but the voltage gap between the old and new batteries is not small. But there is no more accurate reference, so let's think of a galvanic battery. Take him as a reference voltage, and use him to calculate the current, as long as it can conform to Ohm's law. Later, when conditions permit, we will talk about the issue of standardization.

It seems that building an industrial system is not an easy task, and it takes a lot of effort, especially at the initial stage.

Now if you want to solve the problem, the easiest way is to make zinc-manganese dry batteries. However, to make zinc-manganese batteries, manganese dioxide, ammonium chloride, toner, graphite and metal zinc are needed. However, Song Yingxing's "Heavenly Creations" was published by Chongzhen ten years ago, five years ago, and it recorded the smelting method of metal zinc. In my previous life, I seemed to have heard that there was a record of zinc use in the Song Dynasty of China. I think there should be such a thing as zinc by now. Everything is ready, only zinc is needed.

Zhang Zhimu decided to meet Mr. Lu Bingyi to see if Mr. Lu knew about zinc.

Mr. Lo's office is like a battlefield command center, with large maps on the wall and documents such as maps on the desk. More than a dozen people in Mr. Lu's house were pointing to a map with him, studying something together.

Someone reminded Lu Bingyi that Zhang Zhimu had arrived, and Lu Bingyi even explained a few words to these people, turned around and asked Zhang Zhimu: "Mr. Zhang, when you come to me, there must be something." We're busy drawing out the plans. Ouyang He's Bagua City is a bit interesting, and if the city expands in the future, it can continue to expand in this way. Very interesting. ”

Zhang Zhimu saw that Lu Bingyi was busy, and hurriedly said: "Then I'll make a long story short and don't delay your time." How much do you know about Song Yingxing? ”

Lu Bingyi said: "We can be regarded as friends. This person went to Beijing six times to catch the exam and failed to pass, but this person is very smart. When his "Heavenly Creations" was not written, he visited me in Yangzhou, and we talked about a lot of things. There was even something I told him. However, after the publication of his "Heavenly Creations", we have never seen him again. His book was published by Chongzhen in ten years, and it was written a little earlier. I heard that he is now going back to Jiangxi to be an official. ”

Zhang Zhimu asked: "He introduced the smelting method of zinc in "Heavenly Creation". I want to know, can this zinc be bought in the Ming Dynasty? ”

Lu Bingyi knew that Zhang Zhimu must be making something new again, and said: "The method of making this zinc has long been available, but I haven't found any use for this thing." It's just that it is somewhat useful in copper. So very few people get this thing, if Mr. Zhang wants to use this thing, we can also use calamine to refine it ourselves. There is calamine in nearby Shandong. ”

Zhang Zhimu was very disappointed when he heard this: "Then wait for the spring next year." In fact, Zhang Zhimu knows that zinc is everywhere, and many lead ores are associated with zinc.

Lu Bingyi said: "But, Mr. Zhang." I've been thinking that Song Yingxing should be used by us. This person is now in Jiangxi, he is well aware of the corruption of the imperial court, when the Ming Dynasty is not guaranteed, we go to invite him, with the situation of the kiln, this person will definitely be moved. In fact, there are many things in our kiln gang, which can no longer be explained clearly by his "Heavenly Creation". By this alone, this man will come to the kiln. ”

Zhang Zhimu is also interested in Song Yingxing, and his "Heavenly Creation" is simply an encyclopedia. This person must also be extraordinary. However, at present, Yaogang does not have the conditions to invite this person, in fact, as Lu Bingyi said, he came, and many things were only for learning. But this man's influence cannot but be said to be too great, and now he has many disciples, and most of them are skilled craftsmen. Of course, it is a good thing to be able to win such people.

Zhang Zhimu didn't want to say too much about these things in his heart, and said: "This matter, I have the opportunity to contact him and pave the way for him in the future." Regarding zinc, I'm asking Mr. Lu if he knows where it is. However, I have an idea that we should organize people to specialize in geological research, such as where there are what minerals and so on. Now I want to find a kind of phosphate rock, and no one knows if I ask everywhere, which will affect our development in the future. ”

Lu Bingyi understood what Zhang Zhimu said, he said: "We can select some people in the smelter, they have experience in dealing with ore, let them do this work, and slowly write a book about ore." In addition, we have tens of thousands of people in the kiln, and there are people from all over the world, and they may know what you are looking for. ”

Listening to what Lu Bingyi said, Zhang Zhimu felt that yes, can the masses be mobilized? Zhang Zhimu wanted to find apatite, and he asked many people, but he didn't know.

Before Zhang Zhimu left Lu Bingyi, he said to him: "The matter of finding ore must be taken seriously, and a department must be organized, and Mr. Lu will be directly responsible for this matter, and this department will be in charge of you first." ”

Lu Bingyi said: "Okay, I'll arrange this." Zhang Zhimu knows Lu Bingyi very well, and as long as he agrees to something, he will definitely implement it properly.

Lu Bingyi also knew that if it wasn't a very important matter, Zhang Zhimu would not arrange for him to take care of it personally.

Back in the office, Yang Yulin told Zhang Zhimu that Xiurong Zhixian was coming. Zhang Zhimu thought to himself, it's almost the New Year, is the prefect coming to rub some oil?

Zhang Zhimu entered the office and saw Lu Chengxiang talking there with the magistrate.

After all, this is the official of the parents, Zhang Zhimu went over to give a salute and said, "Let the adults wait for a long time, and then they have something to go out." ”

The prefect also replied: "I know that Zhang Dongjia has always been very busy, and I came to disturb me today." Zhang Zhimu has always hated these politeness, but he can't help it, and he slowly gets used to it.

The magistrate is also a straightforward person, and when everyone sat down, he said: "Zhang Dongjia, I don't come to the door for nothing, and I still have a request for Zhang Dongjia today." We have suffered a severe drought in Shanxi for several consecutive years, and countless people have died. But it has not improved, outside our Xiurong City, many people die of cold and hunger every day, I am a small county, there is no silver and no food in my hands, I am helpless, there is no way, I beg you to come today for those hungry people who are freezing and starving. ”
