Problems solved by technology

[0002] Wind turbines will generate electricity when there is wind. Its internal structure is complex, there are many transmission parts, it is inconvenient to use, and it is prone to poor connection, which leads to a decrease in power generation efficiency. increase, so the overall needs to be improved
In addition, if the wind is too strong and the load of the wind turbine is exceeded, the coil disk will be easily burned out, which will directly affect the subsequent power generation. Therefore, the existing generator cannot control the speed of the wind blade and is not flexible enough. There are certain security risks

Abstract

The invention discloses a permanent magnetic variable-speed wind power generation apparatus with a protection function. The permanent magnetic variable-speed wind power generation apparatus is characterized by comprising a shell; a first input rotor with a first shaft lever is arranged in the shell; the first shaft lever is provided with a protection mechanism; the protection mechanism comprises a brake block and a holder, wherein the brake block is arranged on the outer wall of the first shaft lever, and the holder is arranged corresponding to the brake block; the holder is fixedly arranged on the inner wall of the shell through a supporting seat; the holder is connected with an external handle through a brake cable. The permanent magnetic variable-speed wind power generation apparatus disclosed by the invention has the advantages that the rotation of fan blades can be controlled according to the need of the actual condition; the operation is comparatively convenient; meanwhile, the installation is flexible, and the overall safety performance is high.

Description

technical field [0001] The invention relates to a permanent magnet variable speed wind power generator with protection function. Background technique [0002] Wind turbines will generate electricity when there is wind. Its internal structure is complex, there are many transmission parts, it is inconvenient to use, and it is prone to poor connection, which leads to a decrease in power generation efficiency. increase, so the overall needs to be improved. In addition, if the wind is too strong and the load of the wind turbine is exceeded, the coil disk will be easily burned out, which will directly affect the subsequent power generation. Therefore, the existing generator cannot control the speed of the wind blade and is not flexible enough. There are certain security risks. Contents of the invention [0003] The object of the present invention is to provide a permanent magnet variable-speed wind power generation device with protection function, which can control the rotatio...
