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.

The utility model discloses a kind of cooling devices for casting production of high efficiency energy saving, it is related to casting production technical field, including base and support frame, the support frame is set on the base, further include cooling mechanism, set on the support frame;Heat dissipation mechanism, set on the support frame, the heat dissipation mechanism includes: mounting, have two, and two mounting are set in the support frame;Mounting bracket, mounting bracket is set in the mounting;Driving motor, set in the mounting bracket;Fan blade, the driving motor output end;Fixed plate, set on the mounting piece.This device is discharged in time to the heat generated inside this device by setting heat dissipation mechanism, accelerates the cooling work of this device, can also collect water vapor in time, can also prevent water vapor from leaving the interior of this device in large quantities, ensure the use of water source.

This invention relates to a modular heat recovery tower comprising at least a first module and a second module stacked together. The first module includes a first mounting structure at least at its upper edge, the first mounting structure comprising a vertical portion and an outwardly oriented horizontal portion, and the second module includes a second mounting structure at least at its lower edge, the second mounting structure comprising a vertical portion and an outwardly oriented horizontal portion. The first and second mounting structures are adapted to mate with each other. At least one sealing strip is disposed between the horizontal portions of the first and second mounting structures. The sealing strip is part of a sealing member that further includes a compressible profile seal, and the compressible profile seal is connected to the sealing strip. The compressible profile seal is configured to abut against the junction of the horizontal and vertical portions of the first mounting structure.

The utility model relates to the technical field of livestock breeding equipment, concretely to a device of cattle stable weighing, including base and four door columns, the top of base is connected with door column fixedly, the top of base is provided with the weighter, both sides of base all are connected with the inclined plate fixedly, and a plurality of railings are fixedly connected between every two far away door columns, the utility model drives the gear to rotate through the drive motor in the fixed block, since the gear is engaged with the rack plate, when the gear rotates then will drive the rack plate to move to the inside of weighing equipment, when the rack plate moves to the inside of weighing equipment will drive the baffle to move synchronously, since having two baffles, and the baffle is opposite setting, when two baffles all move to the inside of weighing equipment will contact each other, and the advancing route of cattle is blocked, thereby making cattle movable space reduce, and thereby reducing the activity range and frequency of cattle, and thereby increasing the precision of weighing.
