[0002] Culvert refers to a pipe buried below the ground surface, cast with reinforced concrete, commonly known as cement pipe. Small culverts are also made of metal materials. It is used as a water diversion pipe under the entire cofferdam dam, and is generally used as a water transmission pipe. Cement pipes are mostly used as culverts for water supply and drainage pipes in most cities in my country. Due to the deep burial, it is easy to cause silt and other debris to accumulate during the long-term water flow, resulting in poor water flow or complete inability to flow. The current dredging method is generally to drain the water in the culvert first, and then manually enter the culvert to manually dredge, and then carry the silt out of the culvert on foot and pour it into a certain place for centralized cleaning. This will require a large amount of work and a long time, which will consume a lot of manpower and time, reduce work efficiency, and the dredging is not thorough, and there are also safety hazards.

Several tips are fixedly installed on one side of the rotating part, and an auxiliary breaking part is installed on the outer periphery of the rotating part. The sewage suction pipe of the sewage suction truck passes through the moving part and is inserted into the moving part, and can suck out the broken sludge. The moving part and the rotating part are placed in the culvert. The moving part drives the rotating part to move in the culvert. During the movement, the components in the moving part control the rotating part to rotate, driving the auxiliary breaking part to rotate. The tip on one side of the rotating part breaks up the lumps of sludge in the culvert. At the same time, the auxiliary breaking part also breaks up the sludge adhered to the inner wall of the culvert. The double breaking operation can break up the accumulated sludge, which is convenient for the sewage suction pipe to suck out better.

[0017] Specifically, the moving part described in this embodiment includes: A fixed plate 1, wherein a plurality of push components are movably mounted on one side of the fixed plate 1, and components in the push components are in contact with the inner wall of the culvert; An annular groove 2, wherein the annular groove 2 is formed in the fixing plate 1, and an annular guide groove 3 is formed on an inner wall of one side of the annular groove 2; The gear ring 4 is located in the annular groove 2, and a plurality of guide blocks are fixedly installed on one side of the gear ring 4. The guide blocks are inserted into the guide groove 3, and the gear ring 4 is connected to the connecting piece.

[0018] The sewage suction pipe of the sewage suction truck passes through the center of the fixed plate 1, the center of the annular groove 2 is concentric with the center of the fixed plate 1, and several guide blocks are evenly distributed with the center of the annular groove 2. A sealed electric reciprocating motor is fixedly installed on the inner wall of the annular groove 2. A gear is fixedly installed on the end of the output shaft of the sealed reciprocating motor. The gear is meshed with the ring gear 4, and the sealed reciprocating motor drives the gear to rotate. The gear is meshed with the ring gear 4, and drives the ring gear 4 to rotate. Through the cooperation of the guide block and the guide groove 3, the ring gear 4 can be kept stable during the rotation process. The reciprocating rotation of the ring gear 4 drives the connecting part to swing back and forth, and then drives the rotating part to swing back and forth, so that the tip of the rotating part crushes the sludge, and also drives the auxiliary breaking part to rotate. The auxiliary breaking part crushes the sludge adhered to the inner wall of the culvert, so that the sludge in the culvert is more fragmented, and the agglomerated sludge is prevented from being sucked out by the sewage suction pipe.

[0019] Furthermore, the pushing assembly described in this embodiment includes: A support plate 7, one side of which is fixedly connected to one side of the fixing plate 1; Sealed motor, on the outer side of the sealed motor fixed mounting support plate 7, the output shaft end of the sealed motor is fixedly mounted with a screw 8; Nut 9, the nut 9 is fixedly mounted on one side of the fixing plate 1, and the screw rod 8 passes through the corresponding nut 9; A connecting plate 10, wherein the connecting plate 10 is connected to a bearing at one end of the screw rod 8, and a moving wheel 11 is movably mounted on the outer side of the connecting plate 10; The guide sleeve 12 is fixedly installed on one side of the nut 9 , and a guide rod 13 is provided in the guide sleeve 12 , and one end of the guide rod 13 is fixedly connected to the connecting plate 10 .

The four nuts 9 are evenly distributed with the center of the fixed plate 1 as the center of the circle. A distance sensor is installed on the outer side of the connecting plate 10. The distance sensor detects the distance between the moving wheel 11 and the inner wall of the culvert, so that the four moving wheels 11 are in contact with the inner wall of the culvert, and the fixed plate 1 can be placed at the center of the culvert. The moving wheel 11 has a motor, and the sealed motor controls the screw 8 to rotate, and the screw 8 drives the connecting plate 10, The moving wheel 11 moves toward the inner wall of the culvert, and through the cooperation of the guide sleeve 12 and the guide rod 13, the connecting plate 10 will not rotate with the screw 8 during the movement. When the moving wheel 11 contacts the inner wall, the sealing motor stops working, that is, the screw 8 stops rotating. At this time, the motor on the moving wheel 11 controls the moving wheel 11 to rotate, and the moving wheel 11 pushes the fixed plate 1 and the rotating part to move in the culvert and move deeper into the culvert. The moving wheel 11 can be adjusted according to culverts of different diameters, so that the moving part and the rotating part can be used in culverts of different diameters.
