In the early morning of the next day, Miao Tianfu took a few villagers to carry the burden and send the tourists out of the mountain.

And Yunyi didn't go to see off the tourists, and after getting up in the morning, after eating, he walked out of the mountain with his eldest father, and Li Donglai with burdens and other things. Today, Yunyi took her father and Li Dong out of the mountain for the purpose of ordering a set of small household hydropower equipment to transport into the mountain.

Qingyun Mountain Village is more than four kilometers away from the mountain in a straight line, and if you look at the actual mountain road, I am afraid that it is as many as six or seven kilometers; Moreover, this mountain road is more complicated, rugged and changeable, and the road conditions are more dangerous.

With such a topography, if you want to send wires from outside the mountains in, it is not impossible to do it, but the cost is too high; In addition, there is only one village in Qingyun Mountain where the traffic situation is so bad, but there are only six or seven hundred people, and from the perspective of the people of the Municipal Power Supply Bureau, it is purely in vain to send electricity here.

Therefore, the above problems have made Qingyun Mountain Village one of the few places in China that does not have access to electricity; The civilization of electricity, after being invented in England in the eighteenth century, has been forgotten by the times for almost three centuries.

The Municipal Power Supply Bureau does not send electricity, and the cost of pulling wires from outside the mountain is too high, and it is unrealistic, although it is convenient to use solar energy like Yunyi, but the cost is too high, and the people in the village cannot afford it.

Therefore, Yunyi planned to let the village use small hydropower projects from the beginning.

A few people set off from more than seven o'clock in the morning, and at one o'clock in the afternoon, they met Miao Tianfu and a few people in the mountain pass. In the motor market in Yishi, I bought a small water generator for household use, as well as inverters, wires, batteries, sockets, lights and other household appliances.

While purchasing this kind of equipment, Yunyi explained the price, advantages and disadvantages of these products to Miao Tianfu and a few people, so that when the villagers of Qingyunshan Village install it in the future, they can have a few people who understand, instead of needing to follow them every time.

Small hydropower generator for household use is a kind of generator specially used in mountainous areas or sparsely populated areas, the power of this generator is small, the general family will not exceed 500 watts, a little larger in 300 kilowatts, and the most used is 200 watts.

Yunyi looked at several small hydropower generators, and chose the most used axial flow small hydropower motor in the three types of hydropower motors: axial flow, double impact and single impact.

Axial flow micro hydropower generator is a kind of micro generator used in mountain areas where water resources such as creeks and rivers are abundant, but the flow is not very large.

The characteristics of this axial flow generator are to use the centrifugal force generated by the flow of water as the power, so that this mode of operation makes this generator do not have much requirement for the drop of water, as long as the flow rate of the stream exceeds one meter per second, the flow rate is enough in less than 0.003 cubic meters per second, and it is a generator specially used in the low flow rate stream.

This generator is easy to install and simple to use; When installing, find a place in the creek with a slight drop of more than one meter, connect the drop on the creek with a large-diameter water pipe, and flow the stream water out of the axial flow generator through the water pipe, and generate electricity through the rotational power brought by the flow rate of the stream drop.

Qingyun Creek, which flows down from Qingyun Mountain, which is nearly a kilometer high, is enough to provide countless locations for installing small hydropower plants, and the small hydropower in the eldest girl's house is naturally installed in the waterway closest to the village.

Although the power generation of such an axial motor is low, it is stable enough and can afford a TV and two electric lights at the same time, which is enough for a villager to use.

Moreover, if there are many electrical appliances in the villagers' homes, they can also use the inverter to invert the current, and then use the battery to save it and use it after the inverter changes.

Although the price of this axial generator is more than 2,000, plus the inverter and wire storage batteries, as well as electric appliances such as electric lights, the total price is more than 6,000, but Yunyi feels that the money is worth it.

"Boss, settle accounts for us, we want this set of small hydropower equipment!" After selecting the things, Yunyi beckoned the shopkeeper to come over and settle the accounts.

"It's a total of six thousand seven hundred and five, you just give six thousand seven, and the fraction is counted!"

The chubby boss said with a smile, usually in a mountain village, as long as there is a family that buys such a set of equipment, it will not take long to sell a lot of sets, after all, here in your province, there are often many places in the mountains where three or five households are a small village, and there must be no electricity.

Yunyi smiled slightly, thinking that this boss was very good at being a person, so he took out his bank card and prepared to pay the bill.

"Boss, give you money!" The eldest girl's father took the first step, took out a thick wad of 100 yuan bills from his close-fitting clothes, and paid the bill in front of Yunyi.

"Big brother, I'll pay you the bill, the conditions in your family are not too good, I don't lack this money!" Looking at the eyes of the eldest girl's father, Yunyi said sincerely, he really wanted to help the eldest girl's family.

"Hehe, big brother, I have money, I've worked for you for the past few months, and my monthly salary is so much, I can get this money without any effort!" The eldest girl's father looked at Yunyi with a smile, and then said with a little emotion:

"Big brother, don't you often say that only those who know how to save themselves are worthy of being rescued; Since the installation of water and electricity has so many benefits for your own home, why do you need to go to such great lengths to help us, but we are unconscious? ”

Looking at the serious eyes of the eldest girl's father, and then listening to his tone with a bit of gambling, Yun Yi couldn't help but be slightly happy in his heart: his efforts were not in vain, and in Qingyun Mountain Village, there was finally someone who could save himself....

"Bolt, well done!" Miao Tianfu also patted the eldest girl's father's shoulder happily, and was slightly excited to make him turn over and over with only this sentence, and said with emotion.

The eldest girl's father paid the bill, and the dozen or so people carried this set of equipment and walked out of the hardware general store, ready to take a bus out of the city.

"Uncle Tianfu, you take Yunyi and Brother Shuan and them first, I want to go to the haberdashery market to buy something!" Following behind everyone and not speaking all the time, Li Donglai suddenly said to Miao Tianfu, who has the highest seniority.

"Well, you go!" Miao Tianfu didn't think much about it, so he nodded in agreement; Every time the people in the village go out of the mountains, they always buy some daily necessities to go back, such as sugar, tea, oil, salt, and other things for the family.

"Brother Donglai, didn't we buy food and drink for half a year when we went out of the mountain last time, why do you want to buy it again this time?" The eldest girl's father smiled, and said casually with Li Donglai.

"I'm not going to buy things for the house, I'm going to wholesale a little haberdashery and sell it to the villagers and tourists!" Li Donglai shook his head slightly, and told a few people about a business opportunity that he had long fancied.

"Hey, you have a good eye for Donglai!" Hearing Li Donglai say this, everyone suddenly remembered the tourists who came to the village some time ago, and often complained that there was no place to buy things in the village.

Because Li Donglai went to wholesale haberdashery, everyone waited at the bus stop for a while before Li Donglai came back with two loads of haberdashery.

Because the time was a little tight, so everyone's lunch was solved casually on the road, and after non-stop rushing, finally at ten o'clock in the evening, the people who carried things returned to Qingyun Mountain Village.

After telling everyone that he would start preparing to install small hydropower the next day, Yunyi went home to rest
