The 91 meter long wind blade requires oversized and overlong screws with a diameter of 20 to 42. According to relevant public information, the blades in the wind industry are mainly fixed with two medium-sized blackened studs high strength and very large and super long bolts with a diameter of 20 to 42. Strength level requirements are generally. 8.8 and 12.9. The conversion of wind kinetic energy into mechanical kinetic energy, and then the conversion of mechanical energy into electrical kinetic energy, constitutes wind energy production. The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then use a speed multiplier to increase the rotation speed to induce the generator to produce electricity. According to current wind turbine technology, electricity production can begin at break-down speede about three meters per second (the degree of breeze). ,Wind power generation is generating excitement around the world,because wind power generation does not require the use of fuel,and does not produce radiation or air pollution. The devices required to produce wind energy are called wind turbines. This type of wind turbine can be roughly divided into three parts: the wind wheel includes the tail rudder, the generator and the iron tower. Large wind power plants generally do not have tail rudders, and usually only small ones, including domestic power plants, do. tail rudders.
The steps are: Find out by asking NetEase.
1. First, the motor part of the old ceiling fan was dismantled and the necessary components for wind power generation were obtained, such as fan blades, generators andthe batteries.
2. Fix the fan blades on the fan shaft to ensure that the blades can rotate and the installation is firm.
3. Install the generator on the mechanical part of the ceiling fan, make sure the generator is aligned with the fan shaft and secure it with screws.
