An anti-slip block 12 is fixedly connected to the outer surface of the connecting shaft 8, and the outer surface of the anti-slip block 12 is rotatably connected to the connecting rod 9. A spring 13 is slidably sleeved on the outer surface of the limit rod 6, and one end of the spring 13 is fixedly connected to the upper surface of the slider 7. The end of the spring 13 away from the slider 7 is fixedly connected to the side inner wall of the connecting block 5. A sliding groove 15 is provided on the connecting block 5, and the outer surface of the slider 7 is slidably connected to the sliding groove 15. The number of the plug blocks 11 is multiple and distributed in a rectangular array, and the number of the fixing grooves 16 is multiple and distributed in a rectangular array.

[0024] Working principle: When the oil-immersed hydraulic pump station 1 needs to be maintained, the moving connecting rod 9 can simultaneously drive the plug block 11, the connecting strip 10, the connecting shaft 8, and the anti-dropping block 12 to move by pulling the connecting rod 9, so that the moving connecting shaft 8 can drive the slider 7 to move horizontally on the limit rod 6 while squeezing the spring 13 on the inner wall of the connecting block 5, so that the spring 13 is in a taut state. When the moved plug block 11 is separated from the fixing groove 16, the connection between the positioning block 3 and the docking block 4 can be released. When the moved plug block 11 is not affected by the docking block 4 after flipping, the flipping connecting block 11 can be turned over. The connecting rod 9 makes the flipped connecting rod 9 drive the connecting strip 10 and the plug block 11 to flip around the connecting shaft 8 and the anti-dropping block 12 as the central axis. When the flipped plug block 11 no longer corresponds to the fixed groove 16, the pulled connecting rod 9 is released, so that the spring 13 is no longer restricted by the tension and rebounds, so that the rebounding spring 13 drives the slider 7, the connecting shaft 8, the connecting rod 9, the connecting strip 10, the plug block 11 and the anti-dropping block 12 to move. Because the plug block 11 no longer corresponds to the fixed groove 16, the plug block 11 will not be inserted into the fixed groove 16, thereby facilitating the subsequent connection between the positioning block 3 and the docking block 4, and then After that, the protective cover 2 is pulled to remove the protective cover 2 from the oil-immersed hydraulic pump station 1, so that the electrical equipment and the oil tank in the oil-immersed hydraulic pump station 1 can be maintained. When the equipment and the oil tank in the oil-immersed hydraulic pump station 1 are maintained, the docking block 4 is inserted into the positioning groove 14 on the positioning block 3 to achieve a preliminary connection between the oil-immersed hydraulic pump station 1 and the protective cover 2, and then the connecting rod 9 is pulled to make the moving connecting rod 9 drive the slider 7, the connecting shaft 8, the connecting strip 10, the plug block 11 and the anti-dropping block 12 to move while keeping the spring 13 in a taut state. When the moved plug block 11 does not fall due to After the docking block 4 is affected by the flipping, the connecting rod 9 is flipped in the opposite direction, so that the flipped connecting rod 9 drives the connecting strip 10 and the plug block 11 to flip. When the flipped plug block 11 corresponds to the fixed groove 16, the pulled connecting rod 9 is released, so that the spring 13 is no longer restricted by the tension and rebounds, so that the rebounded spring 13 drives the slider 7, the connecting shaft 8, the connecting rod 9, the connecting strip 10, the plug block 11 and the anti-slip block 12 to move. When the moved plug block 11 is inserted into the fixed groove 16, the fixation between the positioning block 3 and the docking block 4 is completed, thereby realizing the connection between the oil-immersed hydraulic pump station 1 and the protective cover 2.
