[0004] Since the debris in the pipe is relatively viscous, after the rotating structure breaks up the debris, some of the debris may still adhere to the inner wall of the pipe. At this time, the debris will still adhere to the pipe when water flows through, making the unclogging effect of the unclogging device poor. Summary of the invention
[0005] In order to improve the problem that debris still adheres to the pipe after the dredging device has been used, the present application provides a municipal engineering pipeline drainage dredging device.

[0007] By adopting the above technical solution, the debris is broken up by the rotating structure. Since the guide bar abuts against the pipe wall, the debris can enter the collection groove along the guide bar, so that the debris will not continue to stay in the pipe, thereby reducing the possibility of the debris still adhering to the inner wall of the pipe after being broken up, so that the debris can be collected by the collection ring, so that the subsequent sewage can pass through the pipe smoothly.

[0011] By adopting the above technical solution, the rotating sleeve is driven to rotate by the rotating driving member, and the rotating sleeve drives the rotating member to rotate. Since the collecting ring is arranged on the rotating sleeve, the collecting ring can rotate together with the rotating sleeve. The water in the collecting tank is affected by the centrifugal force, so that the water in the collecting tank can be discharged from the perforation, further reducing the accumulation of water in the collecting tank.

[0013] By adopting the above technical solution, the staff inserts the fixing bar into the fixing groove so that the rotating part is installed on the rotating sleeve, and then the staff installs the fixing cover on the rotating sleeve and inserts the stop bar into the stop hole so that the stop bar limits the fixing bar and makes it difficult for the fixing bar to disengage from the fixing groove, so that the rotating part and the rotating sleeve can be more stable, preventing the rotating part from disengaging from the rotating sleeve during rotation.
[0014] Optionally, the guide bar blocks the opening of the collecting groove, a guide groove connected to the collecting groove is formed on the guide bar, a sealing cloth is rotatably connected to the guide groove, and the sealing cloth is used to block the opening of the guide groove.
[0015] By adopting the above technical solution, the guide groove is blocked by the blocking cloth so that debris cannot escape from the guide groove.

[0017] By adopting the above technical solution, when the rotating part rotates, the second magnet is slidably connected to the rotating part, and the second magnet is affected by the centrifugal force, so that the second magnet is not in the moving path of the first magnet, so that the second magnet will not drive the first magnet to move, and the first magnet will not drive the sealing cloth to seal the guide groove through the connecting rope; when the rotating part does not rotate, the second magnet can fall, so that the second magnet is in the moving path of the first magnet, so that the second magnet absorbs the first magnet, and the first magnet drives the sealing cloth to move through the connecting rope, so that the sealing cloth blocks the guide groove and prevents debris from escaping from the guide groove.
[0018] Optionally, a moving spring is provided on the first magnet, and the moving spring drives the first magnet to move in a direction away from the rotating member; when the moving spring is in a stretched state, the blocking cloth blocks the guide groove.
[0019] By adopting the above technical solution, the first magnet slot is driven to move away from the rotating part by the moving spring.

[0020] Optionally, the stop bar is provided with a third magnet for adsorbing the second magnet, and when the rotating member does not rotate, the third magnet adsorbs the second magnet, and the second magnet is located on the moving path of the first magnet.
[0021] By adopting the above technical solution, when the stop bar is inserted into the stop hole and the rotating part does not rotate, the third magnet can adsorb the second magnet, so that the second magnet can be stably located on the moving path of the first magnet, thereby reducing the problem of the second magnet not moving to the moving path of the first magnet due to gravity or other reasons such as obstruction of debris.
