[0002] The gearbox in a wind turbine is an important mechanical component. Its main function is to transmit the power generated by the wind rotor to the generator and make it obtain a corresponding speed. Usually, the speed of the wind rotor is very low, far from the 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.

[0003] According to a gearbox oil change mechanism disclosed on the patent website (authorization announcement number: CN213236023U), "The utility model relates to the technical field of gearboxes, and in particular to a gearbox oil change mechanism. It includes a work surface, a support foot is provided below the work surface, support plates are welded on both sides of the work surface, a hydraulic cylinder is fixed to the support plate by bolts, an oil collecting box is bolted to the bottom of the work surface, a hose is connected to the oil collecting box, and a joint is provided at the end of the hose, a pad is welded to one side of the upper end of the work surface, a motor is bolted to the pad, the motor is connected to the reducer, and a connector is installed on the output shaft of the reducer. When the gearbox oil change mechanism is in use, the reducer is driven by the motor, and after the connector is connected to the transmission shaft exposed on the gearbox, the motor drives the gears in the gearbox to rotate, and clean engine oil is slowly added to the injection port on the gearbox synchronously, and the old engine oil is discharged at the oil discharge port. Through continuous circulation, the old engine oil is replaced as much as possible to meet the oil change demand."

[0004] Based on the above, the applicant believes that there are the following defects:
