Abstract
The utility model discloses a high-power vertical shaft wind turbine. A blade moves by taking a blade shaft as the axle center, and the large areas for a blade to move on the two sides of the blade shaft are different. After the blade rotates to the left side, an elastic push plate on the blade is blocked by a speed limiter, the plane of the blade is gradually rotated to be vertical with the wind direction, and the acting force of the wind is enormous. After the blade rotates to the right side, the elastic push plate on the blade is separated from the speed limiter for self-rotating, the plane of the blade is gradually rotated to be parallel with the wind direction, the wind is dead against the side surface, the wind resistance is small, and the efficiency is high. When a storm happens, the thrusting force on the outer side of the blade shaft is larger than the elasticity of a spring on the speed limiter, the speed limiter is automatically pushed by the blade, and the plane of the left blade and the wind direction form a certain angle, therefore, the storm wind is limited to continuously thrust the blade, and the stability of the generating capacity and the safety of the whole machine are ensured. The vertical shaft wind turbine adopts a thin and rotary blade with large rotating areas, therefore, the weight is light, the start-up wind speed is low, the rotor spoke formed by a conical tube, a columnar pipe and a blade bearing pedestal is long, the conical tube, the columnar pipe and the blade bearing pedestal are mutually connected by flanges, the action spot of the wind power is centralized at the outer end of the rotor spoke, and the rated power is high. The vertical shaft wind turbine has the advantages of normal operation in the big or small wind, high efficiency, high rated power, automatic storm wind conversion, simple structure, low transportation and installation cost and convenient construction.
