When in use, each electrical device can be started and operated through the electric control cabinet. The power connection method of each electrical device is an existing mature technology and is well known to people in this field, so it will not be described in detail here.

[0034] When in use, the protective outer tube 2 is placed inside the drainage inner tube 1, and the threaded barrel 12 is rotated manually or with a driving device. When the threaded barrel 12 rotates, the threaded rod 13 moves along the limit rod 19 with the clamping ring 14 until the clamping ring 14 contacts the outer wall of the drainage inner tube 1, thereby fixing the drainage inner tube 1 inside the protective outer tube 2;

[0035] When the inner drainage pipe 1 leaks, the water slides down the outer wall of the inner drainage pipe 1 into the water receiving box 5 and then falls into the installation box 4. When the water level in the installation box 4 rises, the float 7 generates buoyancy, driving the float rod 8 to move upward in the guide sleeve 6 until the top of the float rod 8 touches the switch 9. The alarm 10 will sound an alarm. After detecting the signal of the alarm 10, the controller 11 will transmit it to the terminal to alert the staff.

[0036] When dirt accumulates on the inner wall of the drainage inner pipe 1, the driving device can be connected to the driving sleeve 18 to drive the rotating rod 16 to rotate on the bearing plate 15. When the rotating rod 16 rotates, the cleaning blade 17 will rotate along the inner wall of the drainage inner pipe 1 to scrape off the dirt on the inner wall of the drainage inner pipe 1.

[0037] Compared with related technologies, the municipal sewage drainage pipe assembly provided by the utility model has the following beneficial effects:

[0038] The utility model provides a municipal sewage drainage pipe assembly, which can protect the drainage inner pipe 1 by arranging a protective outer pipe 2 outside the drainage inner pipe 1, and can effectively prevent the pipe from being invaded by foreign substances (such as sand, pebbles, etc.), avoid the pipe from being damaged or worn, thereby extending the service life of the pipe, and can also prevent the pipe from being affected by oxidation, avoid rapid aging of the pipe, and reduce the service life of the pipe. The water collection box 5 can collect water when the drainage inner pipe 1 leaks, and trigger the switch 9 to perform alarm detection, which can accurately locate the leakage position, help maintenance personnel quickly find the leakage point, reduce the search time, and improve maintenance efficiency. Alarms and signals can be issued through the alarm 10 and the controller 11 to help staff find leakage in time, and maintenance personnel can Repair water leakage problems more quickly and avoid the inconvenience caused by long-term water outages to residents or businesses. The inner drainage pipe 1 can be fixed by the clamping ring 14 that can move on the threaded barrel 12, and the inner drainage pipe 1 is fixed in the protective outer pipe 2. The dirt on the inner wall of the inner drainage pipe 1 can be scraped off by the rotating cleaning blades 17 to ensure that the inner drainage pipe 1 can drain smoothly. The driving device can be conveniently connected through the driving sleeve 18 to facilitate the driving of the cleaning blades 17 to rotate in the inner drainage pipe 1 to achieve automatic cleaning. The limiting rod 19 can slide along the groove 20 on the threaded rod 13 when the threaded rod 13 moves, guide the threaded rod 13, and prevent the clamping ring 14 from rotating with the threaded barrel 12.
