[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current.

[0003] In the prior art, gearboxes are widely used in wind turbines. They are often used in wind turbines and are an important mechanical component. The main function of the gearbox is to transmit the power generated by the wind wheel under the action of wind to the generator and make it obtain a corresponding rotation speed. Usually, the rotation speed of the wind wheel is very low, far from the rotation speed required by the generator to generate electricity. It must be achieved through the speed-increasing effect of the gear pair of the gearbox, so the gearbox is also called a speed-increasing box.

Detection of different gearboxes requires replacement of detection equipment, which increases the detection cost, has low detection efficiency and low practicality. Therefore, the utility model proposes a wind turbine gearbox fault detection device to solve the above problems. Utility Model Content
