Embodiment 1

[0023] see Figure 1-4 , a dredging device for the inner wall of a large-diameter water supply and drainage pipeline, including a bracket 1, on which a sewage hole 12 corresponding to the pipeline 8 is arranged, and on the bracket 1, a horizontal plate 4 is driven and connected by a vertical reciprocating mechanism, and the horizontal plate 4 is provided with a rotating mechanism extending to the inside of the pipeline 8. The rotating mechanism is connected with a scraper 5 abutting against the inner wall of the pipeline 8 through an adjustment structure. The bottom of the rotating mechanism is provided with a nozzle 7 facing the inner wall of the pipeline 8. The nozzle 7 is connected to the outside Pressure water connection.

[0024] When the pipeline 8 is desilted, the pipeline 8 is vertically placed on the support 1, and the drain hole 12 on the support 1 corresponds to the inside of the pipeline 8, so that the sludge is discharged from the drain hole 12 conveniently.

Embodiment 2

[0029] On the basis of Example 1, in order to improve the adaptability of the dredging device, that is, to be able to dredge water supply and drainage pipes with different inner diameters, the device is also provided with an adjustment structure, which specifically includes a rotating column embedded in the rotating column Two threaded rods 19 with opposite helical directions fixed coaxially on 21 are screwed with threaded sleeves 18 on the two threaded rods 19 , and a support rod 6 is hinged between the threaded sleeves 18 and the scraper 5 . A rotating shaft 24 is pivotally connected to the rotating column 21 , a main gear 25 is sheathed and fixed on the rotating shaft 24 , and an auxiliary gear 23 meshing with the main gear 25 is coaxially fixed on the threaded rod 19 .

[0030] The main gear 25 can be driven to rotate by rotating the rotating shaft 24, and the main gear 25 drives the threaded rod 19 to rotate through the secondary gear 23 meshed with it. , the threaded sle...

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...
