The remaining oil and impurities at the bottom of the oil tank are discharged through the oil delivery pipe 12 and are sealed and transported to the inside of the receiving barrel 4. The receiving barrel 4 is used for storage. When the oil pipeline 12 needs to be disassembled for cleaning and maintenance, the sealing component 1 can be used to easily release the fixation of the oil pipeline 12 in the connecting seat 11, so that the oil pipeline 12 can be easily disassembled for cleaning or replacement, effectively improving the convenience of the later maintenance of the oil pipeline 12 and improving the maintenance efficiency. When the inside of the receiving barrel 4 needs to be cleaned, the cleaning liquid is input into the inside of the receiving barrel 4, the motor 6 is started to work, and the column 15 is driven to rotate by the output end of the motor 6, thereby driving the wall cleaning component 12 to rotate by the column 15.

When the column 15 is moved During rotation, the spring plate 202 is synchronously driven to rotate by the column rod 15, so that the round protrusion a203 and the round protrusion b204 rotate relative to each other, so that the round protrusion a203 continuously knocks on the bottom side wall of the receiving barrel 4, causing the side wall of the receiving barrel 4 to vibrate continuously, accelerating the falling of stubborn impurities adhering to the inner wall of the receiving barrel 4, preventing the impurities from being deposited at the bottom of the receiving barrel 4, and further improving the cleaning effect and efficiency of the interior of the receiving barrel 4.

[0040] This solution has the following working process: by inserting one end of the oil delivery pipe 12 into the inside of the connecting seat 11, by pushing the outer sleeve 103, the outer sleeve 103 drives the connecting rod 101 and the piston plate 102 to move in the liquid cylinder 104, thereby pressing the liquid inside the liquid cylinder 104 into the cavity 106 through the piston plate 102, and the annular rubber block 105 has hydraulic pressure inside, so that the annular rubber block 105 expands, so that the side wall of the annular rubber block 105 is close to the outer side wall of the oil delivery pipe 12, The end of the oil delivery pipe 12 is thereby clamped into the connecting seat 11 and the gap between the outer wall of the oil delivery pipe 12 and the inner wall of the connecting seat 11 is fully blocked, thereby sealing the end of the oil delivery pipe 12 to the connecting seat 11, and the other end of the oil delivery pipe 12 is inserted into the oil tank. The remaining oil and impurities at the bottom of the oil tank are discharged through the oil delivery pipe 12 and are sealed and transported to the inside of the receiving barrel 4; when the oil delivery pipe 12 needs to be disassembled for cleaning and maintenance, the outer sleeve 103 is pulled in the reverse direction so that the piston plate 102 is in The fluid cylinder 104 moves in the opposite direction, thereby releasing the hydraulic pressure inside the cavity 106, that is, releasing the expansion of the annular rubber block 105, releasing the sealing clamping of the oil pipeline 12, and then the oil pipeline 12 can be easily removed for cleaning or replacement, and the output end of the motor 6 drives the column 15 to rotate, thereby driving the connecting rod b303 and the connecting rod a301 to rotate synchronously through the column 15, so that the bristles 304 on the connecting rod a301 and the connecting rod b303 can fully brush the inner wall of the receiving barrel 4. The impurities adhering to the inner wall of the receiving barrel 4 are brushed off and cleaned. When the column 15 rotates, the spring plate 202 is synchronously driven to rotate by the column 15, so that the round protrusion a203 and the round protrusion b204 rotate relative to each other, so that the round protrusion a203 continuously knocks on the bottom side wall of the receiving barrel 4, causing the side wall of the receiving barrel 4 to vibrate continuously, accelerating the falling of stubborn impurities adhering to the inner wall of the receiving barrel 4, and preventing impurities from being deposited at the bottom of the receiving barrel 4.
