Chapter 169 Windmill
In Lanhai City in November, the temperature is still more than [-] degrees, and as Li Chengxin knows, the temperature in his hometown Hongming Village is already close to zero. Every time this season comes, Li Chengxin has to lament the temperature in the north and the south Difference.

After Yuan Zhao's operations, Li Chengxin's schedule was very busy, but fortunately, the live broadcast on the top floor was also part of his work, which allowed Li Chengxin to use it as his time to relax.

Of course, this season, the 200-meter-high top floor is particularly windy, which is a veritable "release".

Brother Xiaoyong, the former biggest supporter of Li Chengxin's top floor project, is still doing closed acting training for "Painting Universe". In theory, Qi Lanting, the core character of this project, started to take over the filming again after learning that "Painting Universe" has no prospects. Started a series.

In the end, Li Chengxin presided over the construction of all the heart pool water circulation systems in this plan.

But fortunately, the attention of this top floor project has become very high after receiving the support of CCTV years ago, so Geyue Entertainment conducted a social solicitation for this water circulation system, and got a lot of feasible plans from various universities and research institutions .

There are several considerations in the construction of water circulation systems.

One is what Qi Lanting proposed before, after the pool water directly receives rainwater, the acidity will gradually increase, so it is necessary to reinject the pool water into the filtration system for filtration.

In addition, winter is coming. On the roof, the cold wind blowing from the north will cause the water surface temperature of the heart pool to drop rapidly and freeze, and there is no running water here, and the creatures in the water will not be able to breathe.Therefore, in order to avoid this situation, the water should also be circulated.

Moreover, with running water, oxygen can be better dissolved into the water, so as to create a friendly environment for living things.

Geyue Entertainment finally selected the plan from an engineering university, which can be said to be the place with the most types of windmills in China.

Speaking of windmills, the huge wind turbines in Europe that use wind power to generate electricity are impressive, and in places such as the Netherlands, there have been mills using windmills since ancient times.The wind turns paddle wheels, which drive mills to grind wheat; or saws that move up and down to saw planks; of course, there are also windmills that use wind to draw water.

And this engineering university has studied all kinds of windmills in the world for decades, and then designed new windmills according to local conditions to be used in the third world and some developing countries that lack electricity, so that wind power can enter the daily life of poor people. in life.

Geyue Entertainment's choice was impossible without political considerations, but for Li Chengxin, it was as long as it worked.

With the help of the masters in the maintenance department, Li Chengxin also read the proposal submitted by the Engineering University.

This scheme is called a vertical-axis windmill, and windmills are divided into horizontal-axis windmills and vertical-axis windmills.Windmills with a horizontal axis are the most common, as are Dutch windmills and wind trams.

The advantage of the vertical axis windmill is that it can accept the wind from all directions.

After the windmill in the scheme is rotated by the wind, the gear set is used to convert the rotating force into up and down motion.Then, just like the principle of the push-type water pump in the early years, the water in the heart pool polluted by various organisms in the water and urban rainwater is pumped up, sent to the high rise, and refilled into the oak barrels used as the filtration system to filter again Clean, so as to make the pool water flow, but also create small streams and waterfalls, so as to attract more creatures to come.

"This design is really good!" Li Chengxin exclaimed, "That's it!"

After deciding to make an appointment, Li Chengxin met several college students who were helping to take charge of the project.

Everything started from scratch. After assigning some tasks, several students began to bend stainless steel pipes into the required structure with a hydraulic pipe bending machine according to the structure of the top floor.Hydraulic pipe bender is a new type of pipe bending tool with pipe bending function and jacking function. It is mainly used in pipe installation and repair in factories, docks, warehouses, etc.

Li Chengxin had just completed a few coastal projects with students from Ocean College, and this time he worked with students from Engineering University to build a wind-driven water pumping system suitable for the top floor of Geyue Entertainment, and brought netizens to see various new tools.

There are also students helping to introduce: "Using this hydraulic pipe bender, in theory, only one-fifteenth of the force can be used to bend iron rods."

[Now schools can afford these new tools, and our construction site is still using non-hydraulic torsion bending tools]

[I feel that the university has not experienced these fun projects, is it a loss? 】

【Excuse me, how much force does it take to bend a person...】

Li Chengxin was happy to have so much free labor, and started chatting with the students beside him.

"Are these structures difficult for you?"

"It's not difficult. I like to build Gunpla. In comparison, the piping system is much simpler."

"Engineering universities really have high requirements for mechanics!"

"That's natural! We are also professional in building various types of windmills. There are many windmills on the streets and roofs of our school that are our experimental products."

The students took out their tablet computers and showed some of the windmill projects they participated in in front of the live broadcast screen.

"Wind energy resources are a very clean renewable energy source. It refers to the uneven heating of the earth's surface caused by solar radiation, which causes uneven heating in the atmosphere, so that the air moves along the horizontal direction and the kinetic energy formed by air flow. It is also the energy of solar energy. It is a form of conversion, but the cost of wind energy development and utilization is lower than that of solar energy, and it is the most promising energy source among renewable energy sources.”

In addition to the group that made the pipes, another group of students used steel pipes to make the internal structure of the wind rotor, and another group of students used wood to make the support of the windmill at the top of the building.The high platform made of solid fir is huge, almost as high as a two-story building, adding a few meters to the height of the Geyue Entertainment Building.

In order to prevent the windmill from being blown away by the strong wind at a height of 200 meters, the support must be very strong. In order to reduce the wind surface of the support, the wood with a square cross section is used.The bracket is divided into two layers, the top layer is the space for fixing the rotor, while the lower layer is the structure that transforms the wind force into the force of pumping water.

"Zicheng, do you want to do some work?"

The student building the wooden scaffolding above greeted.

[Submit it, it's your show anyway, let's do something! 】

【Zicheng, don't go, this is more than 200 meters high, if you fall, you will be gone...】

Regarding this proposal of the students, there are supporters and there are those who disapprove.

In the end, Li Chengxin tied the safety rope and went on stage.

All he had to do was climb to the top of the bracket and nail up the last part that fixed the rotor.

With the help of several students and staff, Li Chengxin managed to climb to the top of the bracket, and he could see the whole Lanhai City in his eyes.

Seeing this, Li Chengxin's feet softened: "I'd better sit down."

Driving nails into wood with a power drill was a bit difficult due to unsteady footing.

It took a long time, and Li Chengxin, who was moving bit by bit at the top, finally installed the last four fixing screws.

"I did it!" Li Chengxin said, sitting on the top of the bracket with some lack of confidence, and then carefully climbed down the bracket with the help of a group of people.

　Thank you book friends for the monthly pass of "Wearing No Words"!
