The next morning, it wasn't until six o'clock that Yunyi woke up from his sleep.

Yesterday afternoon, a few people rushed back with a set of small hydropower equipment, but Yunyi was tired; An axial flow hydroelectric generator is more than 70 catties, plus four batteries and an inverter weighing more than 20 catties, and the weight of more than 300 catties is enough for eight people to pick it up in turn.

And the other few people helped Li Dong pick out haberdashery.

Here, Yunyi had just finished exercising, and when the meal was ready to eat, the eldest girl went to Yunyi's small courtyard and told Yunyi that Miao Tianfu and others were already at home, waiting for Yunyi to guide these people to help install the axial flow water motor.

After Yun Yi hurriedly ate a few bites of food, he followed the eldest girl to her house.

There are a lot of people in the small courtyard of the big girl's house, in addition to the village party secretary Miao Tianfu, there are more than 20 villagers such as Miao Dahu, Li Donglai, Li Erming, Li Zhuzi, Miao Shishi, etc., these are people who are more active in the village.

Of course, not all of them who come here are active, and there are also daughters-in-law at home who are more shrewd, such as Yunyi's neighbor Li Zhuzi, who was brought by his daughter-in-law Zhang Cuihua, and asked him to see if it would work to install small hydropower.

Qingshan Creek is a small stream flowing out of the springs on the main peak of Qingyun Mountain, after gathering together, it meanders all the way down along the north main peak of Qingyun Mountain, and finally flows into the Qingyun River more than two kilometers southwest of Qingyun Mountain Village, and finally joins a river that is not famous in Guizhou Province.

Because Qingshan Creek is a small stream on a mountain, it often has different widths and depths in many places due to terrain.

For example, in some places, the terrain is gentle, and there is a large area of low-lying land, so it is easy for Qingshan Creek to retain a lot of water to form a small lake, and the water flow in such places will be very gentle, and the water surface is relatively wide; For example, Qingxi Lake on the edge of Yunyi vegetable field is the most typical representative.

In some places, the water flow is very fast because of the huge drop between the rocks and the narrow place where the stream flows, and the stream is narrow but deep, and even small waterfalls are formed in some places.

The place chosen by the ancestors of Qingyun Mountain Village is very good, this is just the place where the north main peak of Qingyun Mountain and the three peaks of the east and west main peaks intersect, and it can be regarded as the remaining vein of the north main peak of Qingyun Mountain, and the place where this village is located is a piece of land on the north main peak that is nearly one square kilometer higher than the surrounding area.

This kind of terrain is very good, there is no need to worry about the flash flood rushing here, and it also allows the Qingyun Creek that originates on the north main peak to come from the back, and after walking around the village for most of the circle in the east, Qingyun Creek leaves the village from the southwest, so that the people in the village do not have the trouble of carrying water.

The place where Yunyi and the others are going is Qingyunxi, which is less than 500 meters away from the big girl's house, and is going to install small hydropower here.

The terrain here is very suitable, Yunyi just took a few casual glances here, and then chose a place.

The average width of this section of the creek is only about 1.5 meters, the depth is about 60 centimeters, and the flow rate is about 2 meters per second, which is very suitable for impacting the axial flow hydroelectric motor.

Moreover, the shape of the bell mouth here just presses the water pipe directly under the bell mouth, and it is directly connected to the water motor to generate electricity, and it is not even necessary to build it with cement.

After choosing the terrain, Yunyi asked a few people to start preparing for installation.

First of all, he began to dig at the lower end of the horn mouth, with a drop of more than one meter, and after leveling the terrain here, he ordered everyone to set the four ten-centimeter-thick wooden stakes that had been prepared long ago deep in the water.

These stakes are soaked in oil, the common wooden poles; It can stay in the water for more than 30 years without decaying, and if used on land, the wooden stake can last for up to 100 years, which is longer than the most used cement pole today.

After fixing the stakes, Yunyi asked everyone to install the generators on the four stakes.

This axial flow generator is installed in such a way that the motor is at the top, and the bottom is the spiral water inlet and outlet; The biggest advantage of this design is that the lower part of the generator is not immersed in water, which greatly improves the life of the generator.

Fix the generator carefully to prevent the generator from loosening over the years; After that, it's time to start preparing for the last step.

The last process is to install the water inlet, which is a large bell mouth type water inlet, which is connected to the generator, and after the installation is completed, it is completed.

However, this process is more troublesome, and it is necessary to determine the height angle of the inlet and outlet; Because sometimes the water in this small stream is high and the water level is high, and sometimes the water is slow and the water level is low.

If the water level is installed high, the water will not be able to drive the generator when the water level is low.

If the installation is low, when the water level is high, it is easy to form cavitation in the inlet pipe, which affects the stability of the axial flow generator, and even burns the generator.

After adjusting for a while, Yunyi determined the best installation angle, installed the water pipes at the end, and connected the axial flow generator.

As soon as the water pipe is connected, the jubilant stream water enters the axial water generator along the pipe, and after driving the turbine to rotate three times, it is discharged from the water outlet.

"Woooooo

And the generator, with the impact of the water, also came out with a slight, dull running sound.

"Is that all there is to it, Yunyi?" Miao Tianfu looked at the whining generator and couldn't help but look at Yun Yidao suspiciously.

"Well, that's pretty much it, now as long as we connect the wires and inverters, try to make it a real success as long as the lights are on!" Yunyi nodded slightly, to this extent, the substrate is considered successful, only after installing wires, inverters, and batteries, the whole project is finished.

Yun Yi said, holding the wire connected to the generator in his hand, connecting the wire of the inverter, and then pressing the big electric light connected to the inverter.

The lights were on, although the lights were not even obvious under the morning sun, but after all, this was the first villager in Qingyunshan Village to install a power supply, which represented an unusual significance.

Looking at this electric lamp, all the people present were excited, except for Yun Yi, as if this electric light symbolized the future of Qingyun Mountain Village.

After the test, after proving that the whole set of equipment is easy to use, everyone began to erect wires under the guidance of Yunyi.

After the installation of water and electricity, it does not mean that it is completed, but that the electricity must be transported to the eldest girl's house, and it will be considered complete when it can be used. j
