Abstract

The invention discloses a big-diameter water supply and drainage pipeline inner wall desilting device, and relates to the technical field of water supply and drainage. The big-diameter water supply and drainage pipeline inner wall desilting device comprises a support frame, wherein a drainage hole corresponding to a pipeline is formed in the support frame; a horizontal plate is in driving connection on the support frame through a vertical reciprocating mechanism; a rotating mechanism extending to the inside of the pipeline is arranged on the horizontal plate; the rotating mechanism is connected with a scraping plate in abut joint with the inner wall of the pipeline through a regulating structure; a spray head facing the inner wall of the pipeline is arranged at the bottom of the rotating mechanism; and a spray head is connected with an external pressure water source. The scraping plate is driven to rotate through the installed rotating mechanism; the rotating scraping removal on sludgeon the inner wall of the pipeline is realized; meanwhile, through the installed vertical reciprocating mechanism, the scraping plate can be driven to do vertical reciprocating movement, so that the cleaning effect of the pipeline is more sufficient; the impact effect on the sludge on the inner wall of the pipeline is realized through the pressure water flow sprayed out from the installed spray head; the sludge cleaning speed is effectively accelerated; and the pipeline sludge cleaning operation is simple and efficient.

Description

technical field

[0001] The invention relates to the technical field of water supply and drainage, in particular to a dredging device for the inner wall of a large-diameter water supply and drainage pipeline. Background technique

[0002] Water supply and drainage refers to the urban water supply system, drainage system and building water supply and drainage, referred to as water supply and drainage. The water supply and drainage system composed of water supply sources, water intake structures, raw water pipelines, water supply treatment plants and water supply pipe networks has the functions of collecting and transporting raw water and improving water quality. Debris usually accumulates in the water supply and drainage pipes, which can easily cause internal blockage.

[0003] The authorized announcement number is CN101693243B, which discloses a large-diameter sewage pipeline dredging system and method. It has an underground dredging boat and an above-ground operating system...
