Chapter 170 Fan Blade
On the C-shaped frame of the rotor of the vertical axis windmill, light and strong canvas is fixed to make the fan blades. In this way, the wind blowing from any direction can be converted into the power of the windmill.

Using detachable canvas as fan blades not only reduces the weight of the rotor, but also makes the repair and maintenance of the fan blades relatively easy.

This can be said to be the most suitable solution for places with limited weight like the roof.

"Hey! Your structure is ready!"

While everyone was adjusting the rotor, a thick voice came. When everyone saw it, they stopped their work and greeted the visitor.

"Hello, Mr. Qi."

"Why does Mr. Qi have time to come and visit?"

[Who is this person?Feeling very grand]

[This person is Qi Ge, the boss of Ge Yue Entertainment! 】

【Huh?Surname Qi?Isn't that Qi Lanting's father? 】

[Lan Lan's father?Isn’t that just...father-in-law! 】

"I'm here to deliver fan blades to you." The visitor held some canvases in his hand, "These are just sent by the Propaganda Department."

Li Chengxin went up to greet her, quickly took the canvas and thanked her.

Spread the four rectangular canvases in your hands flat on the ground. On the four canvases with a dark cyan background, there are four big white characters "Grid", "Moon", "Entertainment" and "Le".

Seeing these four words, the netizens in the live broadcast room began to discuss again.

[Although it should be these four words, it can be more interesting when you really see it]

[How about the words "Lan Hai No. [-]"? 】

【I feel like I might get beaten up for saying that】

[Since the "Lanhai City" is made of canvas, it can also be given a form of naming the ship. 】

【That's not as good as "Ge Yue Hao", but there is one word missing...】

On each piece of canvas, the employees in charge of the propaganda department punched holes in the four corners, so that the canvas can be fixed.

The student in charge of the windmill rotor looked at it and said, "It's not right to do this."

Then he pulled Li Chengxin and pointed to the C-shaped bracket of the fan blade and said: "To fix the fan blade on the C-shaped bracket, you need to fix the outer corners of the canvas to the two endpoints of 'C' with ropes, and the other side of the canvas One side needs to completely wrap around the connecting line to the left of the 'C'."

Li Chengxin saw that it was indeed the case. If the four points were fixed with ropes, the two points on the left could easily slip off.

Fortunately, this is not a big problem. The master in the maintenance department looked at the requirements and found a solution: "It can be solved with Velcro."

With that said, the master of the maintenance department went downstairs and brought up a roll of Velcro from the maintenance department, and asked Li Chengxin to stick it on the side of the canvas.In this way, when fixing the canvas, he only needs to roll the edge of the canvas around the C-shaped bracket.

This method also has an unexpected advantage, that is, when the wind on the top floor is too strong, the fan blades can be easily removed.

In order to prevent the Velcro from falling off, the Propaganda Department sent another employee up with an electric sewing machine to help Li Chengxin sew the Velcro on the canvas.

After fixing the four pieces of canvas on the fan blades, the fan blades were blown up quickly due to the strong wind on the top floor.

The students who were debugging on the lower level of the fan blades let everyone leave the working area, and then released the brake of the rotor, and the fan blades started to rotate quickly.

In the wind in Lanhai City, the dark cyan fan blades were spinning under the blue sky in late autumn. Looking at it from a fixed angle, the four characters "Ge", "Yue", "Yu" and "Le" appeared in sequence.

[Much better than neon lights]

[I also want a signboard like this, so cool! 】

Li Chengxin tilted his head, looked at it for a while, and then said to the student in charge of debugging: "I think it turns smoothly, what do you think?"

The student also nodded: "It should be fine, I feel like I can go to the next step."

Another student also nodded and said: "This rotation speed should have enough power to pump water up."

Qi Ge asked strangely: "Is there anything left to finish?"

For a moment, Li Chengxin suspected that the big guy standing beside him was Qi Lanting. In a certain way, the father and son were almost off-line.

Li Chengxin replied: "We still need to erect water pipes. In addition, we also need to extend the scope of the heart pool and rebuild several shallower wetland pools."

Qi Ge said with a sneer: "I thought this was done, so I won't disturb you and continue working."

When Qi Ge left, everyone breathed a sigh of relief. Being stared at by the big boss at work, the pressure was not normal.

Then, the student in charge of the rotor explained the basic operation of the rotor to Li Chengxin and the roof maintenance staff. There is also a brake device under the rotor. When the wind is too strong and the rotor rotates at a high speed, the brake device can be used to stop the windmill .

"This system is so powerful and comprehensive." Li Chengxin praised.

The student smiled and said, "Because this is already a few versions of No.20. When the first few versions didn't have brakes, the fan blades were broken and the windmill couldn't be stopped for repairs."

After the rotor passed the trial run test, the student pulled the brake to stop the fan blades.

On the other side, several employees also used the method of making the heart pool before, and then made a shallow wetland. The end of the wetland is just below the windmill.The height of the wetland is only half of the heart pool, so this wetland also creates a small drop at the end of the heart pool.

Since then, the second small waterfall in the plan for the pool on the top floor has also appeared.

After the foam structure of the wetland is completed, there are still a series of steps such as laying tarpaulins, filling soil, and transplanting plants. These are processes that the staff of the live broadcast team are already familiar with.

Then pour a few barrels of rainwater accumulated before into the filtration system, and the wetland is completed.

Although it looks like the plants in the wetland are a bit sluggish now, they will probably stand up after two days when the water flows completely.

After that, it is time to install the water pumping device.

The engineering university students took out several white PVC water pipes from the materials they brought, ready to install them.

At this time, Li Chengxin asked: "Does this water pipe have to be made of PVC?"

The student didn't understand what he meant: "Plastic pipes are not necessary, steel pipes can be used, and PVC pipes are relatively economical."

Li Chengxin heard the students talking about the cost issue, and knew that their understanding direction and their own problems were off the mark, so she said: "I mean, can you use a transparent tube, so that everyone can see the effect more intuitively?" .”

Only then did the student realize: "Of course there is no problem. The advantage of our windmill water pumping system is that it can adapt to local conditions. Generally speaking, there are solutions to these requirements."

After discussing with several other students, a new plan came out.

Therefore, the students replaced the white PVC pipe with a transparent plastic hose of the same diameter, and fixed it on a thin wooden post, so that it can be used like a PVC plastic pipe.
