[0002] A wind turbine pitch charger is a device used in a wind power generation system to charge the pitch system of a wind turbine. In wind power generation, the pitch system is used to adjust the blade angle of the wind turbine to maximize the efficiency of capturing wind energy. A wind turbine pitch charger is usually composed of batteries and can be charged by an external power source or the wind turbine's own power system. These batteries can store electrical energy and provide power to the pitch system when needed. When the wind turbine's power system cannot provide sufficient power, the charger will automatically charge to ensure the normal operation of the pitch system. The normal operation of the pitch system is crucial to the efficiency and stability of wind power generation. By using a wind turbine pitch charger, it can be ensured that the pitch system always has sufficient power supply, thereby achieving optimal performance and reliability of the wind turbine.

[0003] After the production of wind turbine pitch charger is completed, multiple tests are required to complete the final processing. When performing vibration and impact tests, the wind turbine pitch charger needs to be clamped and fixed. However, the existing clamping device still has certain shortcomings when used, that is, when clamping different models of wind turbine pitch chargers, it is impossible to adjust quickly, which delays the test time and affects the production progress.
