Abstract

The invention relates to a wind driven generator. The position of a stator is correspondingly arranged inside a machine cabin, a protrusive ring extends circumferentially toward the axis of the machine cabin, an odd number of supporting parts are arranged on the inner edge of the protrusive ring, and a clamping groove is formed in each supporting part and suitable for inserting and clamping of the inner edge of the protrusive ring. Wedge-shaped supporting heads are arranged at the positions, above the clamping grooves, of the supporting parts, extending protrusions and clamping heads are arranged on the outer edge of the stator, the extending protrusions are matched with concave portions, and the clamping heads are matched with the wedge-shaped supporting heads. Through the structural arrangement, vibration, caused by giant wind speed disturbance, of the stator is dispersed when blades of a rotor rotate, and the stator is embedded more stably. In addition, through arranging cooling liquid circulation tubes on the interlayer and the inner wall of the wind driven generator, the environment where the rotor, a gearbox and a generator body can get sufficient and good heat dissipation is formed, and the working stability of the wind driven generator is improved.

Description

technical field [0001] The invention relates to a wind power generator, which belongs to the technical field of wind power generation. Background technique [0002] With the growth of economy and population, the problem of power resources has become a social problem that has attracted more and more attention. With the gradual deepening of coal resource mining, coal resources are becoming increasingly scarce. At the same time, the smog problem caused by coal-fired power generation has inspired the whole society to consider the rational use of energy to solve the problem of power resources. [0003] Wind power has gradually entered people's field of vision. The energy contained in wind power is huge. If it can be used reasonably and effectively, it will effectively solve the problems of resource scarcity and environmental pollution in coal-fired power generation. According to data calculations, if wind power can be effectively used, then the annual electricity obtained from b...
