Research and Design of Pipe Cleaning Device with Self-Rotation

Background: With more and more blockages in the drainage pipe, recent patents on the design of the pipe cleaning device are also being addressed increasingly. But the current pipe cleaning device has only a single dredging function, and due to the inefficiency of the nozzle head, it cannot be used for cleaning of the seriously blocked pipelines. Objective: In order to solve these problems, a novel pipe cleaning device with self-rotation is proposed and the fluid simulation analysis is adopted for the low-efficiency problem of the nozzle head in this paper. Methods: Firstly, the overall structure of the drainage pipeline cleaning device was designed. Secondly, the size of the nozzle and the nozzle head was determined. Thirdly, the fluid simulation analysis of the nozzle head was carried out to realize the optimal design of the nozzle head. Finally, according to the above design, a prototype was manufactured. Results: This paper presents a novel pipe cleaning device with self-rotation, which is different from current patents. It is divided into the nozzle head system, walking system, cleaning system, threedimensional modeling and assembly of the above three mechanical systems. The simulation results demonstrated that if a deflector is not fixed inside the nozzle head, the pressure of the nozzle head is about 8542751.89Pa, and the flow rate at the outlet of the nozzle head is 354.897m/s. If a deflector is fixed, the corresponding data is 1.32e + 008Pa and 446.336m/s. The result shows that the proposed new nozzle head optimization is effective. Conclusion: The new design solves the problems of the current patents on pipe cleaning device, and solves the key technical problems of inconvenient cleaning of pipe blockage and low efficiency nozzle head under complex working conditions. As a whole, this paper provides new ideas and new methods for the efficient work of pipe cleaning device and the removal of hard dirt on the inner wall of the pipeline.
