[0025] Refer to Figure 1 , the maintenance device 2 includes an adjusting bushing 3 connected to the vehicle body 1 and driven by a motor to rotate, and a maintenance end 4 provided at the end of the adjusting bushing 3. The maintenance end 4 includes a pressing plate 41 movably connected to the adjusting bushing 3, and the pressing plates 41 are circumferentially spaced on the adjusting bushing 3; the pressing plates 41 are arc-shaped to match the inner wall shape of the pipeline, so that the pressing plates 41 are in contact with the inner wall of the pipeline; when the adjusting bushing 3 rotates, the pressing plates 41 rotate and clean the inner wall of the pipeline; on the other hand, an anti-rust coating is applied by the pressing plates 41, which is convenient for repairing the rust removal layer on the inner wall of the pipeline. Thus, the maintenance and repair work of the pipeline can be conveniently completed with only one device.

[0026] Refer to Figure 1 , 2 , the maintenance end 4 further includes a connecting shaft 42 inserted into the adjusting bushing 3. A chute 421 extending axially is provided on the side wall of the connecting shaft 42, and a slider 31 sliding along the chute 421 is fixed on the adjusting bushing 3, so that the connecting shaft 42 can axially move horizontally relative to the adjusting bushing 3; a threaded ring 5 threadedly connected to the connecting shaft 42 and capable of abutting against the adjusting bushing 3 is provided. After the connecting shaft 42 adjusts its position relative to the adjusting bushing 3, the relative positioning of the connecting shaft 42 and the adjusting bushing 3 is realized by the threaded ring 5 abutting against the side wall of the adjusting shaft.

[0027] Refer to Figure 1, each pressing plate 41 is adjusted to fit the inner wall of the pipeline by an adjusting structure 6; the adjusting structure 6 includes an adjusting rod 61 with one end rotatably connected to the adjusting bushing 3 and a connecting rod 62 with one end rotatably connected to the connecting shaft 42. The adjusting rod 61 and the connecting rod 62 extend obliquely upward and intersect relatively, and are connected by a hinge bolt 7. A fixing nut 8 that abuts against the connecting rod 62 is threadedly connected to the hinge bolt 7; the pressing plate 41 is rotatably connected to the other end of the connecting rod 62 away from the connecting shaft 42; when the connecting shaft 42 moves horizontally relative to the adjusting bushing 3, the relative rotation of the adjusting rod 61 and the connecting rod 62 drives the pressing plate 41 to lift and lower, so as to adjust the pressing plate 41 to fit the inner wall of the pipeline with different inner diameters. After the threaded ring 5 and the fixing nut 8 are both locked, the pressing plate 41 is also fixed to the end of the connecting rod 62, which is convenient for pipeline maintenance, cleaning and repair operations.

[0028] Refer to Figure 1 , 2 , the maintenance device 2 further includes a silt cleaning part 9 installed at the front end of the maintenance head 4. The silt cleaning part 9 includes a fixing shaft 92, and the fixing shaft 92 is sleeved and connected to the connecting shaft 42 through an installation structure 10; the installation structure 10 includes an extension plate 101, a clamping block 102 and a clamping groove 103. The extension plate 101 is fixed to the side wall of the fixing shaft 92 corresponding to the connecting shaft 42 and is arranged oppositely.

[0029] Refer to Figure 1 , the silt cleaning part 9 further includes impurity removing rollers 91. A plurality of impurity removing rollers 91 are circumferentially and spacedly fixed at the end of the fixing shaft 92 and extend obliquely outward in a radiation manner, which is convenient for removing sundries such as branches stuck in the pipeline.

[0030] Refer to Figure 1 , 3 , the silt cleaning part 9 further includes a silt cleaning plate 93. The silt cleaning plate 93 is movably connected to the fixing shaft 92. An activity groove 921 is opened on the fixing shaft 92, and a fixing plate 922 is formed by extending on the side wall of the fixing shaft 92 corresponding to the activity groove 921. The silt cleaning plate 93 is inserted into the activity groove 921 and is arranged oppositely at both ends of the activity groove 921, and the silt cleaning plate 93 is fixed to the corresponding position on the fixing plate 922 by a positioning bolt. At this time, the silt cleaning plate 93 can cooperate with the pressing plate 41 to clean the inner wall of the pipeline once, and the pressing plate 41 performs a secondary cleaning.

[0031] Refer to Figure 1 , 3 , the opposite silt cleaning plates 93 can be moved to the middle of the activity groove 921, and a magnetic attraction plate 11 that attracts and fixes each other is fixed at the opposite ends of the adjacent silt cleaning plates 93, making the structure where the opposite silt cleaning plates 93 approach and abut more firm and expanding the silt cleaning range; at this time, the motor is turned off, and the opposite silt cleaning plates 93 can move outwards with the vehicle body 1 to clear the garbage and silt deposited at the bottom of the pipeline, so as to facilitate the staff to clean.

[0032] The working process of the embodiment of the present application is as follows: First, loosen the hinge bolt 7. Through the horizontal movement of the connecting shaft 42 relative to the adjusting sleeve shaft, drive the angle adjustment of the connecting rod 62 and the adjusting rod 61, adjust the height of the pressing plate 41, so that the upper surface of the pressing plate 41 abuts and cooperates with the inner side wall of the pipeline, then tighten the hinge bolt 7, and adjust the circumferential pressing plates 41 in sequence; Fix the dredging plates 93 on both sides of the fixed shaft 92 respectively and tighten the positioning bolts to fix them.

[0033] The vehicle body 1 advances inward from one end of the pipeline. The motor drives the adjusting sleeve 3, the connecting shaft 42 and the fixed shaft 92 to rotate. First, remove sundries such as branches stuck in the pipeline through the impurity removing roller 91, then conduct preliminary dredging by the dredging plate 93, and then conduct secondary dredging by the pressing plate 41. After the dredging operation is completed, move the vehicle body 1 out from the other end of the pipeline. At this time, part of the garbage or silt located at the bottom of the pipeline brought out by the vehicle body 1 can be cleaned.

[0034] Then loosen the positioning bolts, make the opposite dredging plates 93 move downward until they abut against each other and are attracted and combined by the magnetic attraction plate, and then tighten the positioning bolts at the corresponding positions to fix the positions of the dredging plates 93; Make the vehicle body 1 enter reversely from the other end of the pipeline. At this time, the motor is turned off, and keep the dredging plates 93 always located at the bottom of the pipeline. Then, move the vehicle body 1 to the opposite end of the pipeline again to bring out the garbage or silt, and complete the dredging operation.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
