Aerogenerator equipped with multi-layer rotor

Abstract

The invention relates to a wind-driven generator equipped with a plurality of layers of rotors. The rotors are distributed in a plurality of layers and fixed on a same rotor shaft for synchronically driving an electric power generation mechanism to generate electric power; the vanes on the rotors and the rotors are a relatively independent entirety, the vanes are fixed on radial rib plates of shaft center wheels via hinges and can turn over with the hinges as rotor shafts; and the direction and the angle of the turnover are controlled by servo-operated mechanisms fixed inside the rotors. During operation, the each group of vanes can be turned on in downwind direction to push the rotors to rotate by utilizing wind power resource and at the same time turned off in upwind direction to eliminate hindering action of the counterforce of the upwind plane on the rotation of the shaft center wheels, so as to maximally utilize wind power resource. The wind-driven generator can automatically control the opening of the vanes in accordance with wind power strength, so as to ensure the safety during operation process; and can conduct solar electric power generation in fine days with no wind or weak wind by utilizing 'tin foil' area on the surface thereof.

Description

Technical field [0001] The invention relates to a wind power generation device, especially it is equipped with a multi-layer rotor and the blades on the rotor are controlled by a servo motor, which can be automatically opened and closed, and the opening angle of the blades can be automatically adjusted according to the wind force; The horizontal surface of the rotor is also equipped with a layer of "tin foil" area, which can be combined with the solar power generation device inside to generate solar power on a sunny day with no or weak wind. Background technique [0002] At present, the known wind generator consists of several fixed blades installed on a rotatable heart wheel. When the blades are subjected to wind force, they rotate along the wind direction, and then drive the heart wheel and the generator connected to the heart wheel shaft to generate electric energy. , during the rotation process, the blades of this kind of wind power generator play a role in promoting the...
