First build a temporary road and use vehicles to transport the required materials to the location, starting from building the foundation to installing the fan blades, testing and operation. The most important thing is to use a special crane when installing the fan, from bottom to top, level by level, and finally install the main body of the fan and finally the fan blades. Once everything was finished, some roads were revegetated, while others were preserved.
Principle of the fan however, in order to have a certain solidity, the closer the fan blade is to the root, the thicker it becomes. Made of fiberglass. The fiberglass reinforcing ribs are placed in the mold then injected with resin to form. The small wind leaf has a solid structure and the large one has a hollow structure. The hollow part ofThe large blade is almost half a cylinder. It is no exaggeration to say that it is based on the principle of a sail. The installation angle of fan blades is generally adjustable. The wind turbine has a complete constant speed device and a device that automatically brakes, then turns and finally turns again when the wind direction changes. Don't do your own research and development. If you want to make a finished product to sell, simply buy one and then reverse engineer it.
