A first support block 301 is welded on the vehicle body 1. A water pump 302 is installed inside the first support block 301. The water inlet pipe 3 is rotationally connected to the water pump 302. A connecting water pipe 303 is connected to the upper part of the water pump 302. A plurality of water inlet holes 304 are provided on the water inlet pipe 3. A cleaning mechanism is provided on the water inlet pipe 3. It further includes an adjustment mechanism, and the adjustment mechanism is provided on the cleaning mechanism.

[0028] As Figure 1 , Figure 3 and Figures 5 - 10 shown, the cleaning mechanism includes a support plate 4, a sliding plate 5, a dredging brush 6, a sliding column 7, a turntable 8, a limiting block 9, a water storage cavity 10, a water outlet pipe 13, a first high-pressure nozzle 14, a connecting rod 15, and a second high-pressure nozzle 16. A support plate 4 is fixedly connected to the water inlet pipe 3. A plurality of grooves 401 are provided inside the support plate 4. Each groove 401 internally slidably connects a sliding plate 5. A dredging brush 6 is fixedly connected to the end of each sliding plate 5. A sliding column 7 is fixedly connected to each sliding plate 5. A turntable 8 is rotationally connected to the water inlet pipe 3. A plurality of limiting blocks 9 are fixedly connected to the edge position of the turntable 8. The sliding column 7 slides inside the limiting block 9. A water storage cavity 10 is fixedly connected to the right end of the water inlet pipe 3. A plurality of water outlet pipes 13 distributed circumferentially are fixedly connected to the water storage cavity 10. A first high-pressure nozzle 14 is slidably connected inside each water outlet pipe 13. A connecting rod 15 is fixedly connected between each first high-pressure nozzle 14 and the corresponding sliding plate 5. Two second high-pressure nozzles 16 are fixedly connected to the right end of the water storage cavity 10.

[0029] As Figure 9As shown in the figure, the adjustment mechanism includes a second support block 17, a large gear 18, a first support frame 1801, a second motor 19, and a small gear 20. Two second support blocks 17 are welded to the left side of the turntable 8, and a large gear 18 is welded between the two second support blocks 17. Two first support frames 1801 are fixedly connected to the water inlet pipe 3, and a second motor 19 is installed between the two first support frames 1801. A small gear 20 is fixedly connected to the output shaft of the second motor 19, and the small gear 20 meshes with the large gear 18.

[0030] As Figure 1 , Figure 3 and Figure 7 shown in the figure, it further includes a silt removal mechanism. A silt removal mechanism is provided on the water storage chamber 10. The silt removal mechanism includes a first cutting knife 11 and a second cutting knife 12. The first cutting knife 11 and the second cutting knife 12 are fixedly connected to the water storage chamber 10. The second cutting knife 12 is located to the right of the first cutting knife 11. The first cutting knife 11 and the second cutting knife 12 rotate at high speed, which can loosen the tightly packed silt, quickly dredge the water channel, reduce the time required for silt cleaning, and thus improve the overall silt cleaning efficiency.

[0031] As Figures 7 - 8 shown in the figure, it further includes a filter screen 21. A filter screen 21 is fixedly connected to each of the first high-pressure nozzles 14 and the second high-pressure nozzles 16 to prevent silt from falling and blocking the first high-pressure nozzles 14 and the second high-pressure nozzles 16.

[0032] As Figures 1 - 2 shown in the figure, it further includes a detector 22. A detector 22 is welded to the top of the vehicle body 1 so as to be able to view the silt blockage situation in the pipeline in real time.

[0033] At the beginning, the spacing between the multiple dredging brushes 6 is at the minimum state, so that the diameter of the cleaning mechanism is at the minimum state. When it is necessary to perform dredging operations on large-diameter urban environmental protection pipelines, first connect the water pipe to the water receiving pipe 303, send water into the water pump 302, and then start the water pump 302 to transport water from the multiple water inlet holes 304 to the water inlet pipe 3. Subsequently, the vehicle body 1 is controlled to be outside the pipeline that needs to be dredged, and the clogging situation in the pipeline is checked in real time by starting the detector 22, and then the second motor 19 is started, and the output shaft of the second motor 19 drives the small gear 20 to rotate in parallel with the large gear 18. The first high-pressure nozzle 14 is meshed with the first gear 18, thereby causing the large gear 18 to drive the turntable 8 to rotate, causing the slide post 7 to slide forward in the limit block 9. The slide post 7 simultaneously drives the slide plate 5 to move outward in the groove 401, and the slide plate 5 drives the dredging brush 6 to move outward. The position of the dredging brush 6 can be adjusted according to the diameter of the pipeline so that the dredging brush 6 fits the inner wall of the pipeline. When the dredging brush 6 moves outward, the connecting rod 15 also drives the first high-pressure nozzle 14 to slide outward in the water outlet pipe 13 and close to the inner wall of the pipeline. When the dredging brush 6 and the first high-pressure nozzle 14 move outward to a suitable position, the second motor 19 is turned off, and then the vehicle body 1 is controlled to enter the required position. In the pipeline to be desilted, the first motor 2 is started, and the output shaft of the first motor 2 rotates the water inlet pipe 3 to drive the cleaning mechanism, the adjustment mechanism and the desilting mechanism to rotate. The desilting brush 6 rotates to remove the attachments on the pipeline wall. At this time, the water in the water inlet pipe 3 is pressurized and sprayed out from the first high-pressure nozzle 14 and the second high-pressure nozzle 16 to disperse the silt and blockages in the pipeline. The filter screen 21 can prevent the silt from falling and blocking the first high-pressure nozzle 14 and the second high-pressure nozzle 16. At the same time, the first cutter 11 and the second cutter 12 rotate at a high speed to loosen the tightly accumulated silt, which can quickly dredge the waterway and reduce The time required for dredging is shortened, thereby improving the overall dredging efficiency. After dredging is completed, the first motor 2 is turned off, the vehicle body 1 is controlled to reverse out of the pipeline, the water pipe is disconnected from the water connecting pipe 303, and then the cleaned sludge and waste are collected through special equipment, and subsequent treatment is carried out, such as solid-liquid separation, compression treatment, etc., to ensure that the sludge does not cause secondary pollution to the environment, thereby completing the dredging operation of the urban environmental protection pipeline. When dredging operations are required for small-diameter urban environmental protection pipelines, the above steps are reversed to adjust the positions of the dredging brush 6 and the first high-pressure nozzle 14 again.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
