Wind driven generator brake braking device

Abstract

The invention discloses a wind driven generator brake braking device. The wind driven generator brake braking device comprises a first rotating shaft, a brake box, a hydraulic telescopic rod, a bufferdisc, a fixing ring, an annular brake pad and a brake disc; a driven end of the first rotating shaft is connected with a power input end of an electric generator; a driving end of the first rotatingshaft is connected with a power output end of a fan blade; the brake disc, the annular brake pad, the buffer disc, the fixing ring and the hydraulic telescopic rod are sequentially arranged from the driving end to the driven end of the first rotating shaft; a fixed end of the hydraulic telescopic rod is connected with the inner wall of the brake box; the annular brake pad is connected with the side surface, close to the brake disc, of the buffer disc; the brake disc is provided with brake grooves; and the annular brake pad can be inserted into the brake grooves, braking can be conducted stepwise through the plurality of brake grooves, the service life of the annular brake pad can be prolonged while normal braking is ensured, reaction force generated during braking will be dispersed by thebuffer disc, and thus the stability of the joint between the fixing ring and a buffer ring is ensured.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a braking device for a wind power generator. Background technique [0002] With the development and utilization of non-polluting renewable energy, wind power generation has attracted more and more attention. In recent years, while people are rapidly developing the wind power industry, the control technology and safety requirements for wind power generators are getting higher and higher. [0003] Wind power generation equipment is in a natural environment, and the wind speed changes greatly. If the wind speed is too high, the power generation efficiency of the generator will be relatively low. The highest operating speed will lead to its damage. In order to ensure its braking performance, most of the existing brakes have complex structures and are not easy to replace. Moreover, the reverse force generated during braking is likely to cause torque to the brake pad fixing device...

[0003] Wind power generation equipment is in a natural environment, and the wind speed changes greatly. If the wind speed is too high, the power generation efficiency of the generator will be relatively low. The highest operating speed will lead to its damage. In order to ensure its braking performance, most of the existing brakes have complex structures and are not easy to replace. Moreover, the reverse force generated during braking is likely to cause torque to the brake pad fixing device, thereby affecting its working efficiency.
