Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of positioning devices for a head rotating structure of a wind generator, in particular to a positioning device for a head rotating structure of a wind generator. Background Art
[0002] A wind turbine utilizes wind power to drive the wind rotor to rotate, and then the wind rotor drives the generator to rotate, thereby converting wind energy into electrical energy. A wind direction tracking device and a rotating device are arranged inside the wind turbine. After the wind turbine completes wind direction tracking, it needs to stably work toward the wind. Since the wind direction of natural wind is unstable, the head of the wind turbine will swing. Long-term swinging of the head will easily cause wear of the head and affect the power generation of the generator. Therefore, the rotating device of the wind turbine needs to be designed with a fixing mechanism that can make the wind rotor stably face the wind direction, so that the wind turbine can only be driven by the motor to track the wind direction, and will not be affected by the external natural wind and deviate from the wind direction.
[0003] A positioning device for the head rotation structure of a wind turbine disclosed in the Chinese utility model patent application disclosure CN 220705841 U, although it avoids the damage to the overall strength of the wind turbine housing, when the brake pad is replaced, due to the long-term use of the brake pad, the brake pad is severely worn and needs to be replaced, and the replacement of the brake pad of the equipment is relatively inconvenient and not convenient enough, so there is a problem that the replacement of the brake pad is not convenient enough, and some existing wind turbine fixing mechanisms use a piston to insert a fixed clamp ring to position and fix the rotating device. Since the fixed clamp ring needs to be installed in the head of the wind turbine, the installation method adopted is to use bolts to fix it on the housing of the wind turbine. This method has defects: first, the installation of the bolts requires drilling threaded holes on the housing of the wind turbine, which makes it easy for rainwater to enter from the threaded holes, causing the bolts to rust and be inconvenient to disassemble, so there is a problem of inconvenience in disassembling and assembling the equipment. In summary, the utility model has the problem that the replacement of the brake pad is not convenient enough and the equipment is inconvenient to disassemble and assemble. Utility Model Content
