[0002] Existing sewer dredging vehicles generally use hoses to dredge sewers. When working in a vertical shaft under a manhole cover, it is necessary to manually shake the hose continuously to prevent the hose from bending and clogging, which affects the suction efficiency of the dredging vehicle. Because it is a hose, when it is lowered into the vertical shaft, it may collide with the shaft wall, causing the inlet end of the hose to be adsorbed to the shaft wall, which will also affect the suction efficiency. These phenomena may damage the vacuum pump. At the same time, because a hose is used, its service life is short and the hose needs to be replaced frequently. Summary of the invention

[0022] By adopting the above technical solution, the lateral moving mechanism can control the lateral movement of the sewage suction pipe 10, and the first lifting mechanism and the second lifting mechanism can control the upward and downward movement of the sewage suction pipe 10. This structure is conducive to controlling the movement of the sewage suction pipe, and there is no need to manually support the sewage suction pipe for operation, thereby reducing the labor burden of workers.

[0023] Furthermore, a wear-resistant nylon block is fixedly mounted on the inner contact surface between the position-limiting clamp 9 and the sewage suction pipe 10 .

[0024] By adopting the above technical solution, when the wear-resistant nylon block moves up and down in the sewage suction pipe 10, the wear of the outer surface of the sewage suction pipe 10 caused by the limiting clamp 9 can be effectively reduced, thereby achieving the purpose of extending the service life of the limiting clamp 9 and the sewage suction pipe 10.

[0025] Furthermore, the lateral movement mechanism includes a first slide rail 8 which is laterally fixedly mounted on the chassis 1 , and a first slider 7 which can slide laterally thereon is mounted on the first slide rail 8 , and an end of the first slider 7 is connected to the fixing frame 6 .

[0026] By adopting the above technical solution, the lateral movement of the sewage suction pipe 10 can be better controlled.

[0027] Furthermore, the first lifting mechanism includes a first oil cylinder 13 and a second slide block 14, one end of the first oil cylinder 13 is fixedly mounted on the top of the fixed frame 6, and the other end thereof is connected to the second slide block 14, the fixed frame 6 is installed with a second slide rail, and the second slide block 14 can move vertically up and down on the second slide rail.

[0041] When working, the vehicle drives to the side of the shaft, and according to the distance between the vehicle and the shaft, the telescopic mechanism is controlled to extend, and the movement of the sewage suction pipe 10 is checked in real time through the camera 12, so that the sewage suction pipe 10 is located directly above the shaft, and then the first lifting mechanism is controlled to move downward, and the downward distance of the second lifting mechanism is controlled as needed, and then the vacuum pump is turned on to start the operation, and the sewage or sludge in the shaft is sucked into the sewage tank 2 through the sewage suction pipe 10. During the operation, the movement of the lateral moving mechanism, the telescopic mechanism, and the second lifting mechanism is controlled as needed to ensure that the sewage suction pipe 10 covers the space in the shaft during operation.

[0042] After the operation is completed, the vacuum pump is turned off, the second lifting mechanism moves upward, and the sewage suction pipe 10 is retracted. At the same time, the first lifting mechanism moves upward to increase the distance between the sewage suction pipe 10 and the ground to ensure the vehicle's passability.
