This utility model relates to the field of wind power yaw technology and discloses a waste oil collection device for the maintenance of a wind turbine yaw system. The device includes a yaw main wheel and a track component. The track component includes a calibration plate with a fixing groove at the top. A fixing component is inserted into the inner wall of the fixing groove, and a snap-fit ​​component is fixed to the bottom of the inner wall of the fixing groove. A snap-fit ​​groove is formed at the bottom of the fixing component, and the inner wall of the snap-fit ​​groove is snap-fitted to the surface of the snap-fit ​​component. A sloping shovel is fixed to the side of the fixing component away from the calibration plate, and a backhoe is fixed to the side of the sloping shovel closer to the bottom of the calibration plate. This utility model secures the fixing component to the fixing groove of the calibration plate, ensuring that the bottom of the sloping shovel and the backhoe are tightly fitted to the top of the calibration plate. Thus, during the forward rotation of the yaw main wheel, the sludge on the inner wall of the yaw main wheel is scooped up by the sloping shovel, and the backhoe similarly scoops up the sludge during the reverse rotation. Workers only need to clean the sloping shovel and backhoe periodically.
