Abstract

The invention provides a wind driven generator braking device, and relates to the field of braking devices.The wind driven generator braking device comprises a power generation bin, a transmission shaft, a braking assembly and a heat dissipation assembly, one end of the transmission shaft is arranged in the power generation bin and is in transmission connection with a generator, a brake pad is arranged on the transmission shaft, and the braking assembly is arranged in the power generation bin; the braking assembly is provided with a working end matched with the brake pad, the heat absorption end of the heat dissipation assembly is connected with the working end of the braking assembly, and the heat dissipation end of the heat dissipation assembly is arranged outside the power generation bin. Heat generated during braking cannot be quickly discharged through heat conduction, and then the service life of a brake pad, a brake disc and other electronic elements in a power generation bin is affected.

Description

technical field [0001] The invention relates to the field of braking devices, in particular to a braking device for a wind power generator. Background technique [0002] At present, the wind turbine is one of the most important key equipment in the wind power generation system. The operating status and service life of each part of the wind turbine have an important impact on the safe operation of the entire wind turbine. Wherein, during maintenance, it is necessary to realize shutdown through the braking device. The continuous wear and tear of the brake device during long-term use will inevitably affect the braking performance, thereby affecting the operation safety of the entire system. Actively carrying out the state detection of the brake device is of great importance to the timely handling of problems by maintenance personnel and the safe operation of the entire system. significance. [0003] Due to the large torque of the rotating shaft of wind power generation, it is...
