Self-walking pipe culvert dredging device

Abstract

The invention discloses a self-walking pipe culvert dredging device. The self-walking pipe culvert dredging device comprises a main spray nozzle positioned at the front end and a plurality of auxiliary spray nozzles arranged behind the main spray nozzle, wherein the main spray nozzle and the first auxiliary spray nozzle are connected end to end through a connecting water pipe, the adjacent auxiliary spray nozzles are connected end to end through a connecting water pipe, inner cavities communicate with one another to form a water channel, and the auxiliary spray nozzle at the tail end is connected with a high-pressure hose; a main channel which communicates with the connecting water pipe is arranged in the middle of the main spray nozzle; a water inlet channel which communicates with the corresponding connecting water pipe is arranged in the middle of each auxiliary spray nozzle; a plurality of drainage pipes used for spraying high-pressure water outwards are arranged on the peripheriesof the main channel of the main spray nozzle, one ends of the drainage pipes communicate with the main channel, and the other ends of the drainage pipes are arranged towards the directions of the auxiliary spray nozzles; and a plurality of jet flow pipes are arranged in each auxiliary spray nozzle and the peripheries of the water inlet channel of each auxiliary spray nozzle, one end of each jet flow pipe communicates with the middle of the corresponding water inlet channel, and the other end of each jet flow pipe faces the front end of the adjacent auxiliary spray nozzle. The self-walking pipe culvert dredging device is simple in structure, and can walk and clean pipe culverts without depending on power.

Description

Technical field [0001] The invention relates to a manual digging pile, in particular to a self-propelled pipe culvert dredging device. Background technique [0002] In the existing municipal pipelines, after long-term use of many pipelines, a lot of silt will adhere to the pipe walls. In order to ensure the smoothness of the pipeline and prevent the pipeline from being blocked after long-term use, the pipe culvert needs to be cleaned regularly. At present, most pipe culverts are dredged by high-pressure water washing and other methods. When dredging, the dredging path of the pipeline is limited, and the scouring device is difficult to enter. [0003] In order to solve the above problems, the prior art discloses a sewage pipe cleaning device, which includes a cleaning mechanism and a driving mechanism, the cleaning mechanism includes a base and a spray head arranged on the base; There is a water spray pipe communicating with the spray head, and the drive mechanism drives the base ...

AI Technical Summary

Problems solved by technology

The cleaning device moves axially in the pipeline through the driving mechanism and sprays through the nozzle on the cleaning mechanism. The structure is complex and the cost is high. The driving mechanism walks in the water for a long time and is easily damaged after long-term use.
