I beg you for help regarding the weight of the wind turbine cylinder! ! ! ! !

The wind turbine towers I have seen are all conical, with a maximum diameter of 4000cm and a minimum diameter of 2940cm. The height of the tower is 7000cm. In this way, can't you find the volume and surface area? The volume multiplied by the density is the weight of the steel plate. Isn’t it enough to multiply the surface area by the amount of paint per unit area? The flange is welded separately, and the weight should be marked on the instructions. Just add it.

This 200-meter-high wind power How does a generator convert power into millions of watts of electricity?

First, the windshield turns the propeller, and the rotor inside the tower top turns the drive shaft. The drive shaft is connected to a gearbox, thereby turning the generator to generate electricity. It is not easy to build such a wind turbine. It starts with the propeller. The difficulty of making a propeller lies in the fact that each blade has a curved surface like an airplane. When the wind blows over the blades, it will generate upward force, causing the propeller to rotate. Moreover, it must be long enough and light enough. Therefore, all blades are built from a piece of carbon fiber. Carbon fiber is stronger and lighter than steel, and can make longer blades.

Second, use fiberglass to make an aerodynamic handout shell. First vacuum-pack the fiberglass sheets, and then bake them in this cylindrical oven to form two halves of a perfectly seamless shell. . Anxious to join the two halves of the handout together, the workers first applied a layer of glue to the inside of the bottom of the shell, and also applied it to the top of the carbon fiber one and two, and then carefully dropped the huge 55-meter-long car into the correct position. After the blade is installed in place, the blade needs to be baked again to allow the adhesive to change. After baking, take out the combined handout. At this time, the surface of the blade is not smooth enough, and it needs to be polished with a sand mill. It takes about ten hours to polish each blade to complete.

Third, in nature, the greatest threat to wind turbines is lightning. If lightning hits a hollow propeller, it will quickly heat the internal air and cause it to expand, causing the blade to collapse. In order to prevent being struck by lightning, engineers will install copper bridges on the tips of the blades. This allows the lightning to conduct current to the base of the blade and then to the ground, allowing the lightning to bypass the footprint and protect important components of the generator. Next, we began to install the mini power plant on the wind turbine. This is called the nacelle, which is the core of the generator. The huge reward can generate a lot of torsional force, but it only rotates 30 times per minute. Such a slow speed cannot produce electricity, so The gearbox in the generator converts the low-speed and high-torque rotation of the blades into high-speed torque through the drive shaft. The drive shaft drives the rotating magnet inside the generator. When the magnet rotates, an electromagnetic field is formed, thereby generating electric current.

Fourth, such a generator can generate 3.5 million watts of electricity, enough to supply more than 3,000 households. Each time the magnet rotates, the anode and cathode swap, creating an alternating current. The frequency of cathode and anode exchange depends on the custom of the rotating propeller, but the power grid requires power with a stable frequency, so this converter is installed in the cabin, which can convert the alternating current generated by different wind speeds.It is converted into a stable frequency and sent to the power grid. The assembled cabin weighs 85 tons, which is larger than a double-decker bus. It and other rectangular parts need to be transported in batches by truck, and it takes three days to assemble after arriving at the installation site. Once assembled, these giant wind turbines can provide the city with the electricity it needs.
