The periphery of the bottom end of the disc is fixedly connected with one end of a lock catch, an abutting block is installed at the top end of the rotating disc and is in threaded connection with a shaft rod, and the top end of the shaft rod is fixedly connected with the bottom end of a fixing block. The fan is simple in structure and is provided with the fan blade aligning device, and the bolts and the slotted holes are conveniently fixed.

Description

technical field [0001] The present invention relates to the technical field of wind generators, in particular to a wind generator impeller locking disc. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of wind turbines, generators (including devices), regulators (tails), towers, speed-limiting safety mechanisms, and energy storage devices. The working principle of the wind turbine is relatively simple. The wind wheel rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft, and the generator rotates and generates electricity under the drive of the wind wheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy generator that uses the sun as the heat source an...

Problems solved by technology

When a single blade is installed, the bending moment generated by the weight of the blade will exceed the bearing limit of the impeller locking device. Therefore, for the impeller locking of large wind turbines, the requirements for the impeller locking device are getting higher and higher, and a single impeller locking device is often unable to meet the requirements. Therefore, the current impeller locking device often uses multiple locking pins to lock the rotor together

[0004] Due to machining errors, even if multiple pins are used, only a few pins can bear most of the locking moment. Even if the locking holes are matched, only the paired pins can be improved, and all pins cannot achieve equal load.
