The bottom of the support portion is connected to the machine base, and a U-shaped groove is provided at the top. The size of the U-shaped groove matches the fixed end of the hydraulic cylinder. The fixing member presses above the hydraulic cylinder and is connected to the top surface of the support member through screws. Specifically, the support member is a square column with a U-shaped groove at the top and a horizontal connecting plate perpendicular to it at the bottom, and the fixing member is a flat plate. Further, there are two first brackets, which are arranged at intervals at both ends of the hydraulic cylinder.

[0019] According to a specific embodiment, the third bracket includes a cross beam, the bottom of which is connected to the machine base, and two vertical beams are arranged vertically and parallel at intervals at the top. The distance between the vertical beams matches the outer diameter of the pressure storage cylinder. In addition, elastic pads are provided on the inner sides of the two vertical beams of the third bracket to prevent the outer side of the pressure storage cylinder from being worn.

[0020] The beneficial effects of the present utility model are:

[0021] Set the third support on the base to place the pressure storage cylinder. Then, drive the oil removal plug to move axially from one end to the other inside the pressure storage cylinder through the hydraulic cylinder, so as to remove the cleaning oil remaining on the inner wall of the pressure storage cylinder, and drive and adjust the speed of the hydraulic cylinder through the hydraulic pump, thereby realizing the automation of oil removal from the inner wall of the pressure storage cylinder.
