Municipal drainage pipeline dredging device

Abstract

The invention relates to a municipal drainage pipeline dredging device, and belongs to the technical field of municipal pipeline cleaning. The municipal drainage pipeline dredging device comprises a shell, wherein a water inlet is formed in one end of the shell; jet orifices inclined to one side of the water inlet are formed in the outer wall of the shell; the water inlet communicates with the jet orifices; the jet orifices are uniformly formed in the circumferential direction of the shell at intervals; an impact head is slidably connected to the end, away from the water inlet, of the shell in the axial direction of the shell; and a driving mechanism used for driving the impact head to move on the shell in a reciprocating mode is arranged in the shell. A worker connects a water pipe to the water inlet of the shell, water is introduced into the shell, the water is jetted from the jet orifices and flushes the inner wall of a pipeline, so that the shell moves forwards, then the impact head is driven to move in front of the shell in a reciprocating mode, and when the impact head impacts an obstacle, the forward force of the impact head and the forward force applied to the shell by the water flow act together. The municipal drainage pipeline dredging device has the effect of improving the cleaning effect on the pipeline.

Description

technical field [0001] The present application relates to the field of cleaning municipal pipes, in particular to a device for dredging municipal drainage pipes. Background technique [0002] According to different drainage requirements, municipal pipelines are used in drainage fields such as roads, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields and slope protection caused by high water content, as well as underground in agriculture and gardening Irrigation and drainage systems; internal dredging of municipal pipelines is to dredge and clean the pipelines, scrape and discharge the silt in the pipelines, so as to keep the water conservancy pipelines unimpeded for a long time to prevent urban waterlogging, and the current pipeline dredging work has become a drainage department An important job that cannot be ignored. [0003] The patent with authorized notification number CN208934104U discloses a rotary pipe dredging gun head and a pi...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the pipe dredging gun head clears the obstacles in the forward direction of the gun head through the front water jet port at the front end, but after the water flow sprayed from the front water jet port hits the obstacle The recoil force will be formed, and the forward force generated by the rear water injection nozzle on the inner wall of the pipe and the forward force of the gun head will move forward. The reaction force generated by the jet on the inner wall of the pipe is weakened, so that the cleaning effect of the gun head on the pipe is reduced
