Description

Technical Field

[0002] Existing sewer dredging equipment is mainly used to remove silt, debris, and other substances that have accumulated in sewers over a long period of time, ensuring smooth drainage, preventing blockages and sewage overflows, and thus maintaining the normal operation of the urban drainage system. Its working principle typically utilizes a power unit (such as an engine or motor) to drive various working components. Some systems use robotic arms or scrapers to directly scrape and collect silt from the pipe walls and bottom, while others combine with suction devices to remove the dispersed silt during the dredging process and transport it to a designated location for treatment.

[0003] Existing municipal sewer dredging equipment often uses fixed-size devices that are difficult to adjust to the actual pipe diameter. This results in incomplete coverage of the pipe's inner wall during dredging, leaving some areas without access to silt and affecting the thoroughness of the dredging. Furthermore, it fails to effectively flush away scraped silt during the dredging process, leading to silt accumulation in the pipes and hindering drainage. Even when some devices have flushing capabilities, a stable water supply cannot be guaranteed during rotation, preventing continuous and efficient flushing and further reducing dredging efficiency.
