[0002] Pipeline desilting has become an important task that cannot be ignored by the drainage department. If a large amount of debris and cement sand from infrastructure sites are discharged into the drainage pipe, the sedimentation and siltation will cause the pipe to be blocked. Failure to desilt and dredge the pipe will cause sewage to overflow, pollute the environment, and cause trouble to people's lives. High-pressure water jetting is a widely used desilting method, which uses a high-pressure water jetting vehicle equipped with a large water tank, a motorized hose reel, a high-pressure water pump, a water jet nozzle, etc. During operation, the car engine drives the high-pressure pump, pressurizes the water and sends it into the water jet nozzle. The reaction force generated by the backward jet makes the water jet nozzle and the hose move in the opposite direction, and also cleans the pipe wall at the same time; when the nozzle reaches the downstream inspection well, the motorized winch retracts the hose, and the water jet nozzle continues to spray water to flush the remaining sediment to the downstream inspection well, which is sucked away by the sludge suction truck. However, the existing desilting equipment has some shortcomings, such as:
