When the park was completed, it was a huge hit, because it was no longer the same small dirt enclosure as it used to be, with wide concrete walkways, five large trees that seemed to rise into the sky, and low bushes that had been trimmed into various shapes, and the verdant grass under these bushes.

Of course, there are also those park benches for them to rest, these steel and wood backrest benches are very simple in structure, just a dozen wooden strips with steel pipes and rivets, but they are quite comfortable to sit on, because it has a suitable curvature backwards. They also don't have to worry about the chair tipping over because it has an inverted leg that is the same width as the chair body.

So on the day of the opening of the park, it was not only those small plants with various geometric shapes that opened the eyes of those who came in to play. It is the figure 8 brick made of PP material with hollow in the middle on the ground, which has also become one of the topics of discussion for many people. As for the large expanse of clear glass on top of the wooden corridor on the east side of the park, they were even more amazed.

It's just that today in addition to the original things, there seem to be a lot more things in the park, for example, there are several more small cylinders in the bushes with glass in front and iron shells in the back.

"You baby, tell you not to touch things......"

"Didn't I tell you that the chief said that he wanted to take care of public property, why didn't you ......listen?"

There are even more naughty ones, who were pulled over by their parents, pulled off their pants and spanked their butts.

……

"Chief, do you think the conference can start now?" Chen Youxin held a piece of A4 paper in his hand, which was full of the process of this celebration meeting and some speeches. Looking at the park again, it was already full of people, and although the time had not yet fully arrived, it was almost there.

Huang Shi raised his hand and looked at his watch, it was already 7 o'clock in the evening, and it seemed that he couldn't wait until 7:30 o'clock, because it was completely dark at this time, but fortunately, there were a lot of kerosene lamps on the camp next to him, and the moon in the world also sprinkled silver light on this small island, so the park was not particularly dark, but the people standing on the lawn looked shadowy.

"Okay, Zhang Chen, you turn off the street light switch." Huang Shi turned his head to Zhang Chen, who was standing behind, and said.

Zhang Chen responded, turned around and walked to the large round flower bed, in this garden jar, that is, at the foot of the ancient camphor tree, in addition to the turf, there are flowers of various colors, and now this one has set up an iron box, on which are written in red words "power distribution box" five big characters.

Because it is under the leafy ancient camphor tree, even the moonlight in the sky is blocked by it, and if you don't look at it with your eyes in front, you may not be able to see the words clearly, so Zhang Chen opened the flashlight in his hand, and then wiped a bunch of keys from his waist, and opened the door with it under the reflection of the light.

……

"Wow, what's going on?"

"yes, what is this, why is it so bright."

"Daddy, look, the four little balls on that rod are lit up......"

"Look, look, the little trees behind us are lit up."

"They're still red......"

"You see, there are little green and yellow trees over here."

Looking at the lights that were lit, Chen Youxin's heart was very excited, according to the chief's statement, Dongluo Island has since stepped into the threshold of electricity and electricity, and it is no longer the era of complete manual labor.

He couldn't help but remember that in the afternoon, several of them were called by the chief to the generator room, which was thirty-two meters away from the camp. It was there that he learned that the chief was going to hold a celebration in the evening to celebrate the beginning of a new era, and asked him to write a speech in the vernacular, so that everyone could witness the birth of an era together.

Chen Youxin still has a lot of perceptual understanding of electric lighting, because in the several albums given to them by the chief, there are various buildings and night scenes in the upper realm, and the lights of various colors on the picture are so dazzling. I really didn't expect that from today, this small island will actually have its own bright lights.

The generator room is a rectangular mobile house building, the construction area is not large, that is, about 30 square meters, standing alone in the northeast corner of the camp, on the four sides of the house are written in red letters, "the machine room is heavy, idlers do not approach" or "the machine room is heavy, fireworks are strictly prohibited", and the gate was also locked with a large iron general before.

The generator room was not built in such a remote place to insulate the sound, or to avoid the noise from affecting the people in the camp, because in fact the diesel unit with a silent box was already very quiet. Yellowstone is mainly for safety, in case there is any fire or explosion or other accidents, so that it will not affect the people living in the camp.

The 100 kilowatt Cummins diesel generator set in the room is a long two meters and one five, less than one meter wide, and one meter high is as fast as one meter three, and the net weight of the unit on its open frame will be nearly one ton, although it is not the heaviest, but Huangshi is not superhuman, and after putting it out, there is no way to place it on the pedestal that is poured with cement concrete.

After trying a few times, Huang Shi could only scratch his head and give up, blaming himself for designing this base too small, because it was only as big as this unit, so once the unit was slightly deviated, the height difference would suddenly make the unit slide off the base, and the previous time he almost hit Hong'er who was watching from the side, but several people present were scared enough.

"You said they didn't have anything to do with the wheels on it, and that was too unsafe." Huangshi complained while pondering a countermeasure. It turned out that this 30-centimeter-high pedestal was made in the room, which was completely in accordance with the manual in order to prevent rain, because this mobile house was not equipped with a floor, but now the rain has not come, and it is difficult for me here.

Huang Shi thought about it, there is only one way, first unload the four wheels of the chassis, otherwise there is a way to put it on the pedestal, once the generator set starts, then the huge vibration will also shake it down, then it is better to remove it now, so it can be more safe.

So he had dozens of bricks found and put them under the chassis, and then began to disassemble the wheels, and with such a tool as a wrench, Huang Shi commanded them to do it quickly, and in less than half an hour, the four wheels were removed and placed in a corner of the house.

After putting the unit on the pedestal, it will not run or slip at this time, and several people will work together to push it into the right position. After all this was done, Huang Shi pulled out a wire from the wire of the chassis and said to Su Er, "Fugui, this wire is the grounding wire, in order to prevent leakage, we will connect this wire to the ground nail now." ”

"Chief, if there is a leakage, isn't there a leakage protector on this machine, and will it still work?" Su Er was a little puzzled, he remembered that when the chief introduced the equipment to him the day before, he had said about the leakage protector.

"Regardless of whether there is a leakage protector or not, it is still necessary to ground for safety, because the ground nails are also used to prevent static electricity. Moreover, leakage protectors will generally work, but they all have a response time, so for the sake of insurance, it is better to ground first. ”

With that, he pulled the wire and squatted down, and at the corner of the pedestal there was a wet spot with a copper rod stuck in it, and a small mushroom on its head. This is the ground nail that Huang Shi specially asked Li Yijun to hit after listening to the introduction of the technical staff, using 1. A 5-meter-long copper bar, then drove it into the ground and sprinkled some salt water near the nail.

"Alright, let's get ready for a test flight." Yellowstone stood up and clapped his hands, but after looking around, he realized that he had forgotten one more thing, so he said, "You open all four windows." ”

It turns out that in order to prevent insufficient diesel burning, resulting in the accumulation of carbon monoxide indoors, it may lead to carbon monoxide poisoning of users, and also cause fires, and even cause electric shock accidents. So Huangshi asked Zhang Yongnian to install a glass window in all four directions of the generator room, and even installed a pair of powerful exhaust fans on the windows on the left and right sides of the unit.

It's just that there is no test machine today, and there is no electricity, and the exhaust fan will naturally not work, so Huang Shi asked them to open the windows and doors for mechanical ventilation, and seeing that everything was ready, he waved his hand and said, "Start the test machine." ”

In the early days, diesel engines were started manually, and Huang Shi remembers that when he was in the countryside, the user wrapped a belt around the flywheel, and then pumped it hard, and the flywheel drove the unit to start. Later, there was an improvement, with an additional handle on the flywheel, and the user used the handle to drive the crankshaft to rotate just like a tractor.

Today's diesel unit, the whole unit is still composed of diesel engine, generator, control box, fuel tank, starting and control battery, protection device, emergency cabinet and other components. But there is no need to be so troublesome in starting, so in front of Su Er, it is just a simple management panel, with 6 meters and two buttons, one red and one blue, etc.

Su Er gently pressed the start button, and soon heard the "click" sound of the two coming out of the case, which was particularly light and crisp in this room where everyone was silent, "Chief, I heard the second ring." ”

"Well, good, no glitches." Huang Shi nodded, if he couldn't hear the second sound, he would have to check whether the starting solenoid valve was working properly, if the solenoid coil burned out, the generator would not start, and he would have to send it up for maintenance, which would be very troublesome, and the evening conference would naturally not be opened.

As soon as Huang Shi's words fell, he heard the roar of the machine slowly coming from the chassis, although the sound was not loud, but it was like a muffled drum beating in the hearts of everyone around him, Su Er kept looking at his watch, and looked at the time minute by minute with some nervousness, "Chief, can you close the power switch for it now?" ”

"Wait another three minutes." Huang Shi looked at his watch, and it was only five minutes later, because the diesel generator set could not be powered immediately after starting. It takes 5 to 8 minutes to run at high speed, and the water and oil temperature reach about 60°C before the normal power supply can be carried out. Otherwise, it is easy to cause cracks in the cylinder and cylinder head.
