Abstract

A wind power generation shaft braking device comprises a shaft. A locating ring is arranged outside the shaft and provided with a fastening bolt. The fastening bolt is connected with a solenoid valve. The solenoid valve is connected with a controller. The fastening bolt is controlled to move through the solenoid valve so that the shaft can be clamped. The wind power generation shaft braking device has the advantage of quick deceleration.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a braking device for a wind power generation shaft. Background technique [0002] Wind power generation is one of the sources of daily power supply, and wind power generation drives the fan blades to rotate through the wind, friction electrification, and the process of converting kinetic energy into electrical energy. The braking device, the current braking device adopts soft braking, but the active speed is slow. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the object of the present invention is to provide a wind power generation shaft braking device, which has the characteristics of fast braking. [0004] For reaching above-mentioned purpose, technical scheme of the present invention is as follows: [0005] A shaft braking device for wind power generation, including a shaft, is characte...
