Cutting type auxiliary dredging device for drainage pipe

Abstract

The invention discloses a cutting type auxiliary dredging device for a drainage pipe, and relates to the technical field of drainage pipelines. The cutting type auxiliary dredging device for the drainage pipe comprises an outer shell and an inner pipe coaxially and fixedly connected in the outer shell, wherein the two ends of the inner pipe are both in sealed communication with the drainage pipe, and a cleaning ring is coaxially and rotatably connected in the inner pipe and is in sliding connection in the axial direction; a plurality of cutting knives are connected to the inner circumferential side of the cleaning ring in the radial direction, a control ring is connected to the outer circumferential side of the inner pipe in a threaded mode, and a plurality of magnetic blocks are embedded in the control ring. According to the cutting type auxiliary dredging device for the drainage pipe, flowing sewage forms an impact effect on the cleaning ring and the cutting knives in the inner pipe in the normal drainage process, the cleaning ring moves along the pipe wall of the inner wall, and the control ring in threaded connection with the outer peripheral side of the inner pipe is subjected to counter-acting force of magnetic attraction to the cleaning ring and spirally rotates along the outer peripheral side of the inner pipe when the cleaning ring moves, so that the cleaning ring is magnetically driven to rotate in reverse, the cutting knives of the cleaning ring forms a spiral cutting effect on waste, and the crushing effect on the waste is improved.

Description

technical field [0001] The invention relates to the technical field of drainage pipes, in particular to a drainage pipe cutting auxiliary dredging device. Background technique [0002] During the long-term use of existing drainage pipes, the waste carried in the water flow will not only cause scale on the inner wall of the drainage pipe to affect the drainage rate, but even excessive waste will block the drainage pipe, seriously hindering the normal operation of the drainage pipe. Causes problems of backsoil and inability to drain. Existing drainage pipe dredging devices generally use external tools to dredge the blockage in the pipe through the pipe port. This method is relatively wasteful and easily pollutes the water environment. The odor generated by waste decay greatly affects the senses of dredgers. . Contents of the invention [0003] The present invention proposes a drainage pipe cutting auxiliary dredging device, which aims to solve the problem that in the tradi...
