Forward and reverse rotation energy conversion device of vertical-axis wind turbine rotor and application method

Abstract

The invention relates to a forward and reverse rotation energy conversion device of a vertical-axis wind turbine rotor. The device consists of a rotor friction plate, forward and reverse rotation friction wheels, forward and reverse electromagnetic clutches, a transmission main shaft, an energy storage flywheel, a conversion device frame, a pressing spring, a frame guide rod, a cam groove plate, a slide table linear module, a displacement motor, a travel switch, a reversing controller and the like. When the wind turbine rotor is operated in a reversing area, the driving of the rotor is stopped; and the rotor transfers the remained rotating energy to the energy conversion device through the friction plate and the friction wheels. One friction wheel is pressed to contact with the small radius place of the friction plate to gradually move to the large radius place, so that the slide friction loss in transmission of the friction wheel is reduced; when the rotor is reversed, the other friction wheel is pressed to contact with the large radius place of the friction plate toe gradually move to the small radius place so as to reversely transfer the rotating energy to the rotor; and when the travel of the friction wheel is idle, the contact with the friction plate is separated. The device can effectively reduce the energy consumption in rotor steering.

Description

technical field [0001] The invention relates to the field of vertical-axis wind turbines, in particular to a high-efficiency conversion of forward and reverse energy of a Magnus effect vertical-axis wind turbine rotor. Background technique [0002] In the history of the development of wind power technology, there has been a vertical-axis lift wind turbine based on the Magnus effect. The power blades that generate lift are rotating cylinders mounted on rail trolleys, and the trolleys are placed on On the circular orbit, when the incoming wind blows to the cylinder, the Magnus effect will be produced on the rotating cylinder, that is, on one side of the cylinder, the direction of wind flow is the same as the direction of movement of the cylinder, while on the other side it is opposite, which induces The circulation around the rotating cylinder will generate a lift perpendicular to the wind flow direction (the lift direction points to the same side as the above-mentioned moveme...
