The liquid extraction pipe 31 and the filter barrel 55 are both arranged inside the liquid collection pipe 52, and the diameter of the filter barrel 55 is smaller than that of the liquid collection pipe 5 2 pipe diameter, the diameter of the liquid inlet pipe 54 is equal to the diameter of the filter barrel 55, the liquid inlet pipe 54 is placed at the place where oil needs to be unloaded, the liquid extraction pump 3 is started, and the oil is extracted under the action of the liquid extraction pump 3, and the oil enters the filter barrel 55 through the liquid inlet pipe 54. Impurities such as oil residue in the oil cannot pass through the first filter hole 551 and the second filter hole 552. The filtered oil enters the inside of the liquid inlet pipe 54 through the first filter hole 551 and the second filter hole 552, and finally the oil is extracted through the liquid extraction pipe 31. Impurities such as oil residue remain in the filter barrel 55, completing the filtration of the oil when unloading.

[0025] A first threaded hole 521 is provided on the outer surface of one end of the collecting pipe 52 close to the fixing ring 53, and a second threaded hole 531 is provided on the outer surface of the fixing ring 53. A locking bolt 532 is threadedly connected to the inside of the second threaded hole 531, and the locking bolt 532 is threadedly connected to the first threaded hole 521. Tighten the locking bolt 532 so that the locking bolt 532 passes through the second threaded hole 531 and is connected to the first threaded hole 521, so as to facilitate fixing the fixing ring 53 and the collecting pipe 52. At this time, the filter barrel 55 is inside the collecting pipe 52.

[0026] The liquid extraction pipe 31 is a telescopic hose having good elasticity and flexibility, and is easy to stretch and shrink according to different oil unloading scenarios and needs, making the operation more convenient and flexible.

[0027] A connecting pipe 4 is fixedly provided between the liquid extraction pump 3 and the oil collecting tank 2 to guide the oil extracted by the liquid extraction pump 3 into the oil collecting tank 2 for the convenience of collecting the extracted oil.

[0028] A drain pipe 21 is fixedly connected to the bottom of the oil collecting tank 2, and a valve 211 is fixedly connected to the outer surface of the drain pipe 21.
