Installing a fan is not pouring the foundation, just change it if you make a mistake and break it, but he bought it back for 20 million, and there can be no omission. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Moreover, unlike the pouring of foundation concrete, the installation is a delicate job!

Give them training!

Zhu Changyuan organized all the management personnel, as well as crane drivers and operators, to watch the video he got from the modern society about the installation of the wind turbine in the large conference room.

These videos are given by the manufacturer when buying the fan, and they can be regarded as image versions of the manual.

After watching the video, Yan Hong asked the engineer to explain the technology he brought from modern society to the workers one by one, until all of them understood.

It took two days of training, and when hundreds of people were all familiar with the procedures for installing the fan, the fan installation began.

Choose a sunny day, oh no, a sunny day, and take the soldiers who have been trained to be too skilled to be more proficient and various scientific and technological leaders to go up the mountain to install the wind turbine.

However, what Zhu Changyuan didn't expect was that many residents on the island also spontaneously went up the mountain, either to help, or to go up to see the major events on the island.

Zhu Changning is the earliest mechanical master trained by Zhu Changyuan, he personally ran to the 260-ton crawler crane to operate the crane, and the other personnel operating on a 130-ton crane and a 50-ton crane are also mechanics, all of whom are professionals trained by Zhu Changyuan with skill books.

After the personnel are in place, the workers first carefully scrape away the soil layer buried on the foundation, and then remove the geotextile covering the foundation to reveal the fresh concrete inside.

After so many days of curing and insulation, the concrete has long been hardened and white, and the rings and other steel components embedded on it are firmly fixed in the solidified concrete. Motionless.

"Good, good, this is already good!" Zhu Changyuan is not demanding. After all, it was the concrete that his subordinates mixed with their bare hands, and it was already excellent to have this kind of color.

I saw that the people and machinery ready for installation were already in place. Zhu Changyuan waved his hand and said, "The first thing, hoist the control cabinet first!" According to the windmill hoisting plan and the content of the usual training, the 50-ton small crane was commanded to adjust the control cabinet stored next to it, and then carefully placed it on the embedded parts embedded on the foundation.

The control cabinet is the control center of the entire wind turbine, which can adjust the voltage, current and frequency! The electricity emitted by the wind turbine is first transmitted to the control cabinet for stabilization, and then the control cabinet is output to the outside and connected to the grid for voltage boosting. After the voltage is boosted to 10 thousand volts, it can be transmitted over medium distances.

The control cabinet is installed with the cooperation of the crane and the worker, and the embedded parts of the electric welding and grounding are welded together, which forms a whole with the foundation, and the installation of the first step is completed.

The installation of the control cabinet is very simple, and the simple person who has almost a little hoisting knowledge can get it for him, but the next installation is the main thing.

What's next to install?

Tower!

said that the tower is too elegant, but in fact, it is the big cylinder that stands up for dozens of meters, and it is also the body or legs of the entire fan. This should be easy to understand!

The height of the tower varies, but most of them are above fifty meters, such as the one Zhu Changyuan bought. The overall height of the tower is sixty-two meters.

Some people say that the 62-meter shelf is not it, can't it be lifted directly by a 260-ton crane?

Nonsense, of course not!

Moreover, there is no such installation of shelves in the world.

All the towers are prefabricated and are divided into three sections after leaving the factory, one section by one from the ground to the top, not sixty-two meters in one breath to install, because the tower is a steel structure, and the steel structure is a flexible structure, if the crane lifts one end. It will cause deformation in the middle.

Forget it, let's get down to business!

Zhu Changyuan took a deep breath. Let the workers tie the special wire rope that has been prepared for a long time to the fixed position of the first section of the tower, and then use a 260-ton crane to slowly lift the tower. It then hangs vertically in mid-air.

Align the rings underneath and land slowly!

The first section of the tower, the height of 17 meters, the weight of 52 tons, logically not too heavy, unfortunately, there is a height of 17 meters, it is necessary to have a lifting height of more than 20 meters, so only 260 tons of cranes can meet the requirements.

The huge tower slowly and vertically fell under the lifting of the crane, and the people around involuntarily retreated a distance.

This tower looks a little scary, not to mention the round, the diameter of the entire steel pipe below is four meters, a full four meters!

What is the concept of four meters, that is to say, the hollow bottom area of the tower is a full twelve or thirteen square meters, which should be comparable to a small master bedroom.

The tower slowly descended, and slowly put the control cabinet that had just been installed on the foundation in it, and then, the cylindrical four-meter steel pipe was tightly fitted with the ring piece embedded earlier on the foundation!

"Go! Adjust the position! Zhu Changyuan ordered the workers to step forward.

At this time, the tower was still hoisted in the air by a crane, but it was already very close to the ground, only less than a foot away, so the workers tied the tail end of the tower with a rope, and it was effortless to move it with manpower before and after.

After adjusting the position, dozens of people stepped forward to support him, and then Zhu Changning slowly, slowly, almost a minute to lower a dozen centimeters, and it took three minutes to put the whole big guy on the ground.

"Boom!" Metal clash with a dull thud.

"Good, fast, welding, anchor bolts, high-strength bolts!"

As soon as Zhu Changyuan's voice fell, someone had already prepared everything, went up and screwed the bolts with a wrench, and then, after all the bolts were screwed to death, let people remove the wire rope on the crane!

The first tower was preliminarily installed, and the entire control cabinet was encased in a tower that was hollow like a steel pipe.

Of course, at the bottom of the tower, there is a small door that can be opened to enter, and there is a ladder that spirals up along the tower, and you can go up to the top of the tower along the ladder.

In order for the tower to be strong enough. After Zhu Changyuan put all the bolts on it, he ordered someone to weld the bottom of the tower and the place where the embedded ring piece was in contact with electric welding, so that it would be welded together. The entire tower is stable enough.

When all the welding is done, the installation of this first tower is considered a perfect success!

The first section of the tower is installed. From the lifting to the final installation, it took one hour, that is, two hours.

Doesn't it seem difficult?

No, it should be said that it is easy, if it is compared to the installation of the second and third sections of the tower!

The really hard part is the second verse!

The length of the second tower is 22 meters, which is five meters longer than the first tower, but the weight of the second tower is much lighter than the first. Only forty-one tons.

Why?

Because the second section of the tower is thinner than the first section of the tower, the diameter of the bottom is only a little more than three meters six (the thickness of the entire tower is the higher the thinner, gradually tapering!). ）。

Although the weight is ten tons less, it is more troublesome to install, because this time it is not connected on the foundation, but in the air!

How to connect?

Of course, it still depends on the cooperation of people and cranes.

First, people with walkie-talkies climbed from the bottom of the first section of the tower to the top of the first section through the spiral ladder, and then watched the second section of the tower falling from the sky on the middle operating platform. Command with walkie-talkie.

"A little up, a little more, north. To the north! ”

Yes, that's how it is directed.

Then, under the second section of the tower, it is tied with four long ropes, and the tower that sways with the wind in mid-air is controlled by artificial pulling on the ground.

The person standing on the top of the first section (at this time the first section has been installed and is fixed) must have enough courage and overcome his fear of heights, otherwise he will look down and see that Nima will fall off his head and command a fart.

That's it. With his command, the second section of the tower slowly descended. Until the first person is placed in the middle, and then it lands on top of the head of the first arm. Two sections in one!

"Boom!" A huge sound came out, far farther in mid-air than it had been on the ground before!

"Bang bang." After the two towers are combined, minor adjustments are made again, and then, through the inner flange at the place where the two arms meet, they are rigidly connected together with bolts.

There are many bolts, and the inside of the steel pipe with a diameter of more than three meters is covered with hundreds of high-strength bolt holes, large and small.

The workers went up and worked for half a day before tightening all the bolts on it, and then checked them one by one, and found that the loose ones were tightened again, so checked three times, and after making sure that there was no omission, the installation of the third section of the tower began!

(I've thought about how to describe the flange to you many times, but unfortunately the concubine can't do it, and I don't know the three words of the flange in Baidu, and I saw the picture, in fact, everyone has seen it, but I just don't know what that thing is called!) ）

The installation of the second section of the tower took four hours to adjust, four hours, that is, eight hours! When it's all done, it's getting dark!

Installing this thing is not like pouring concrete, you can work overtime at night, you can't work overtime at night, otherwise you will definitely die.

I had no choice but to do half of it and put it there and rest!

The next day, it was another sunny day, and Zhu Changyuan organized the personnel again early in the morning to start the installation of the third and last tower!

The third section of the tower is twenty-three meters long, and the weight is even lighter, only twenty-seven tons! However, the lifting height was very high, because with the addition of the length of all the pipes this time, it was exactly sixty-two meters.

Coupled with the reserved surplus height, the height of hoisting is even higher.

The installation of the third section of the tower is similar to that of the second section, but it is more difficult, higher and windier!

Zhu Changyuan commanded people, and it took a full five hours to finish!

During this period, because the pipe was too high, a worker was in a trance on the tower, and then fell down and died!

There was no way, it was too high, it was standing on a separate steel pipe, and the wind in the air was strong, so the worker accidentally fell to his death while changing the safety belt.

This is still wearing a seat belt, if you don't wear a seat belt, you don't know how many people will die!

Zhu Changyuan led all the residents of the island to mourn in silence for the warrior who dared to climb to a height of more than 40 meters, and saw him off!

On the third day, I had to continue to do it, and this time the climb was even higher, reaching 62 meters!

At an altitude of 62 meters, the wind can blow people down!

However, the warriors of Sun Moon Island were not afraid and went up hard, and finally the auxiliary crane put the sixty-one-ton generator room on the top of the tower!

The nacelle is large, resembling a small room at the top of the tower, which houses the core technology of wind turbines: generators.

After the nacelle was installed, it took another day to install all the blades on the hub, and then the blades were hoisted together with the hub.

At an altitude of 62 meters, the workers braved the cold and windy weather to finally connect the wheel hub with blades and the engine room.

At the same time, the entire fan was fully installed.

Looking at the towers that looked like optimus pillars towering over the top of a high mountain, the crowd boiled.

"Success, success!"

"My God, what kind of wind turbine is this, Sun Wukong's Ruyi golden hoop stick is nothing more than that, this optimus pillar, do you know how many catties?" Someone asked in a low voice

This happened to be heard by Zhu Changyuan, who picked up the horn and shouted high in the crowd: "Just now I heard someone ask how much this wind turbine weighs, and I told you that the total weight of this wind turbine is two hundred and thirteen tons and a half!" ”

Seeing that the people below were unclear, Zhu Changyuan said again: "If it is converted into our catties, it should be 427,000 catties, do you say that there is no weight of gold hoop sticks!" ”

"Oh my God, isn't the golden hoop stick only 13,500 catties, this guy actually has 420,000 catties, obediently, the golden hoop rod is more than a fraction of it!"

。。。。

Listening to the discussion of the people below, Zhu Changyuan waved them to stop, and said: "Don't talk about it, if you can't send a call, what's the use of reweighting?" After speaking, he said to Yan Hong, who was not far away: "Okay, it's time to turn on." ”

Yan Hong nodded and ordered the power engineer to enter the tower through the small door at the bottom of the tower.

The generators were installed, the power lines were connected, but the blades were still motionless in the wind! It's not broken, it's not that it's not installed, but it's not turned on yet, so naturally it won't be moved, otherwise wouldn't it be dead to work with electricity?

"Power on!" Yan Hong also shouted inside with a loudspeaker.

Three seconds later, the wind blades on the tower slowly moved, rotating very, very slowly, not because the wind was not strong enough, but the weight of the blades plus the hub was more than 30 tons, and it also drove the generator inside, so it naturally rotated very slowly when it started.

However, it is already excellent to be able to start, if the wind is a little weaker, it will be a joke if the windmill does not start!

"Whew!" Seeing the windmill slowly turning, Zhu Changyuan really breathed a long sigh of relief, so many days of hard work were finally not in vain.

Without investigation and full investigation and research, it is also an extremely remarkable thing to be able to build a wind turbine and generate electricity based on its own random conjectures. (To be continued.) )
