It should be noted that if the power drive mechanism 1 adopts an active walking mechanism 102, the walking mechanism 102 can adopt the existing technology, such as the walking power drive and walking control method of the balance car disclosed in Chinese patent CN205554499 U, or adopt the walking drive method of the autonomous walking trolley disclosed in Japanese patent CN305723947S, to realize the walking drive of the dredging device 100 by the power drive mechanism 1. A waterproof machine cover 103 is arranged on the power base 101, and the waterproof machine cover 103 is made of metal waterproof material. A driving motor 104 is arranged in the waterproof machine cover 103, and the driving motor 104 adopts an external power supply or a power battery as energy. A horizontally arranged power shaft 105 is connected to the driving shaft end of the driving motor 104, and the power shaft 105 is sequentially equipped with a brushing mechanism 2 for wiping the inner wall of the pipeline, a flushing mechanism 3 for high-pressure water spraying, and a crushing mechanism 4 for crushing debris on the inner wall of the pipeline along its axial direction from inside to outside. During operation, the driving motor 104 is controlled to drive the power shaft 105 to rotate, driving the brushing mechanism 2 and the crushing mechanism 4 to rotate. The rotating action of the crushing mechanism 4 first crushes the foreign matter on the inner wall of the pipe to be unblocked, and then the flushing mechanism 3 cleans the crushed inner wall of the pipe with high-pressure water. Finally, the brushing mechanism 2 brushes and cleans the cleaned inner wall of the pipe as the power shaft 105 rotates.

[0025] like Figure 1 and Figure 5 As shown, the scrubbing mechanism 2 includes a support disc 201 fixedly mounted on the power shaft 105 and rotating with the power shaft. The outer circumference of the support disc 201 is provided with a plurality of connection ends 202 at equal intervals along its radial direction. The outer end of the connection end 202 is provided with a plug-in slot 2021, and a cleaning brush 203 is inserted into the connection slot of the connection end 202. The cleaning brush 203 is fixedly connected to the connection end 202 through a connection assembly 204; the connection assembly 204 uses bolts and nuts to achieve a fixed connection between the cleaning brush and the connection end. The scrubbing mechanism 2 of this embodiment can replace the soft or hard bristle cleaning brush 203 according to different use environments, which is convenient for the staff to repair and replace the cleaning brush 203, bringing convenience to the staff and flexibility in the use of the equipment.

[0026] like Figures 1 to 4 As shown, the flushing mechanism 3 includes a support frame 301 sleeved outside the power shaft 105, and an annular water tank 302 is coaxially fixedly connected to the outer periphery of the support frame 301, and at least one water inlet port 306 is provided on the side wall of the annular water tank 302; a plurality of flushing water jackets 304 are evenly spaced and distributed on the annular outer wall of the annular water tank 302, and each flushing water jacket 304 is distributed with a plurality of high-pressure nozzles 305.

[0027] like Figure 4 As shown, a fixed sleeve 303 is connected to the center of the support frame 301, a support sleeve 106 is sleeved on the power shaft 105, and the flushing mechanism 3 is fixedly sleeved on the support sleeve 106 through the fixed sleeve 303; the inner walls at both ends of the support sleeve 106 are provided with rolling bearings 107 sleeved on the power shaft. Auxiliary wheel groups 307 are symmetrically arranged on both sides of the lower part of the annular water tank 302. When working, the auxiliary wheel group 307 also adopts an active wheel group or a passive wheel group; in this embodiment, the auxiliary wheel group 307 preferably adopts a passive wheel group that plays an auxiliary role, that is, an unpowered walking wheel group is adopted to cooperate with the walking mechanism 102 to realize the walking drive of the dredging device 100. It should be noted that in this embodiment, the flushing mechanism 3 cooperates with the support sleeve 106 through the fixed sleeve 303 set on its axis to meet the free rotation of the power shaft 105 and keep the flushing mechanism 3 rotating along the inner wall of the pipeline.

[0028] like Figures 1 to 3 As shown, the crushing mechanism 4 includes a support sleeve 401 fixedly mounted on the end of the power shaft 105 and a plurality of crushing rods 402 equidistantly arranged along the circumference of the support sleeve 401. The crushing rods 402 can destroy the impurities accumulated on the inner wall of the pipe when rotating with the power shaft 105, thereby preventing the impurities accumulated inside the pipe from being too large in volume and affecting the cleaning effect of the dredging device on the inner wall of the pipe.

[0029] The working principle or working method of the utility model:

[0030] Move the dredging device 100 to the end of the municipal pipeline to be cleaned, and the power drive mechanism 1 moves forward or backward in an active or passive manner. At the same time, the drive motor 104 is started to drive the power shaft 105 to rotate, driving the scrubbing mechanism 2 and the crushing mechanism 4 to rotate with the shaft. The flushing mechanism 3 is fixed relative to the power shaft 105 and does not rotate with the power shaft.

[0031] During the process of the dredging device moving forward, the crushing mechanism 4 located at the end of the power shaft 105 first contacts the inner wall of the pipeline, and the power shaft drives the support sleeve 401 and its circumferential crushing rod 402 to rotate, which can destroy and crush the foreign matter accumulated on the inner wall of the pipeline, and avoid the foreign matter accumulated inside the pipeline from being too large, which affects the cleaning effect of the dredging device on the inner wall of the pipeline. Secondly, as the dredging device moves forward, the flushing mechanism 3 flushes and washes the inner wall of the pipeline treated by the crushing mechanism 4 with a cleaning liquid. During this process, the flushing mechanism 3 can assist the power drive mechanism 1 in walking and maintain the stability and balance of the dredging device. After the flushing operation, the scrubbing mechanism 2 rotates with the power shaft 105 to scrub the inner wall of the pipeline that has been flushed with high pressure; it should be noted that the scrubbing mechanism 2 can replace the soft or hard bristle cleaning brush 203 according to different use environments, which is convenient for the staff to repair and replace the cleaning brush 203, bringing convenience and flexibility to the staff.

[0032] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
