The rotating shaft 32 is located inside the cooling water tank 3. The driving motor 31 is used to provide power for the rotating shaft 32, so that it is convenient to mechanically drive the rotating shaft 32. The driving motor 31 can also be connected to the control unit of the control block 1 by signal, so as to facilitate the control of the driving motor 31. A gear 33 is fixedly sleeved on the lower end surface of the rotating shaft 32, and multiple gears 33 are distributed in a linear array on the surface of the rotating shaft 32. The different specifications of the multiple gears 33 are used to facilitate the needs of different rotation speeds.

The inner wall of the sleeve 34 meshes with the outer surface of the gear 33 through the latching tooth, and multiple sleeves 34 are respectively meshed with gears 33 of different specifications, so that the rotation speeds of the multiple sleeves 34 are inconsistent, and the adjacent ends of adjacent sleeves 34 are rotatably connected through a bearing, and a winding rod 35 is fixedly connected to the outer surface of the sleeve 34. The surface of the oil pipe 2 is wound around the surface of the winding rod 35, and the sleeve 34 is used to drive the oil pipe 2 to be wound through the winding rod 35, so as to increase the flow time of the hydraulic oil in the cooling water tank 3, and the sleeve 34 is provided to wrap the gear 33 and the rotating shaft 32, so that the specification of the sleeve 34 is larger, thereby avoiding excessive folding of the lower end of the oil pipe 2 and affecting the delivery of the hydraulic oil.
