The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, and then use a speed multiplier to increase the rotation speed to incentivize the generator to produce electricity. According to current wind turbine technology, electricity production can start at a breeze speed of around three meters per second (the breeze level). The small wind power generation system is very efficient, but it is not only composed of a generator head, but a small system with certain technological content: wind turbine + charger + digital inverter. The wind turbine consists of a nose, a rotor, a tail and blades. Each part is important, and the functions of each part are as follows: the blades are used to receive wind energy and convert it into electrical energy through the nose; the tail allows the blades to always face the direction ofu wind to obtain maximum wind energy; the rotor allows the nose to rotate flexibly to reach the tail has the function of adjusting the direction; the nose rotor is a permanent magnet and the stator winding cuts the magnetic lines of force to generate electrical power. As the wind volume is unstable, the wind turbine produces an alternating current of 13 to 25 V, which must be rectified by the charger and then the battery is charged, so that the electrical energy generated by the wind turbine is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use. Mechanical connection and power transmission The horizontal axis fan blades are connected with the universal elastic coupling through the gearbox and its high-speed shaft to transmit torque to the drive shaft of the generator.tor. This coupling must have good damping and vibration absorption. that it absorbs the appropriate amount of radial, axial and some angular deviations, and that the coupling can prevent overloading of the mechanical device. The other type is direct drive fan blades, which are directly connected to the engine without passing through the gearbox.
45,254 vehicles. According to public information surveys, the number of wind blades in China will reach 45,254 in 2021, is expected to reach 70,286 by 2025, and is expected to reach 64,286 by 2025. Pallet truck is a subdivision of special vehicles. It is mainly used to transport wind turbine blades. The pallet truck is a kind of semi-trailer. Because it is very long, it generally adopts an extractable structure. the sections are removed and the rear section is removed, the longest reaches 45 meters.
