Abstract

The invention discloses a self-heat-dissipation wind driven generator speed limiting and braking device which comprises a box body. A generator is fixedly connected to one side of the inner wall of the box body, a small rotating rod is fixedly connected to one end of the generator, a speed change gear box is arranged at the other end of the small rotating rod, the outer wall of the speed change gear box is fixedly connected with the inner wall of the box body, and a large rotating rod is arranged on the inner wall of the speed change gear box. The outer wall of the large rotating rod is fixedly connected with fan blades, the bottom of the box body is fixedly connected with a supporting rod, and an automatic speed limiting mechanism is arranged in the box body. The invention relates to the technical field of wind driven generation. By arranging the automatic speed limiting mechanism, the problem that internal parts are damaged by high temperature caused by overload work of the generator due to the fact that the rotating speed of the small rotating rod is not too high can be solved, the situation that power supply is insufficient due to faults is avoided, and through automatic speed limiting, meanwhile, the time and energy consumed by continuous checking of workers are reduced, the workload is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a self-radiating speed limiting and braking device for a wind power generator. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Using wind power to generate electricity is very environmentally friendly, and wind energy It has huge reserves, so it is increasingly valued by countries all over the world. my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW, of which, the wind energy reserves on land are about 253 million kW (calculated based on the data at a height of 10m above the ground on land). Th...
