Physical inner wall desilting device for large-diameter connecting pipes in water conservancy projects

Abstract

The invention provides a physical inner wall desilting device for large-diameter connecting pipelines in water conservancy projects, which relates to the field of pipeline cleaning, and solves the problem that the scraper is a whole knife structure, and the entire scraper is in contact with the inner wall of the pipeline, and the resistance is relatively large when scraping the silt, and When adjusting the scraping position, it is impossible to quickly adjust the position of the crushing structure while ensuring the scraping efficiency and avoiding missed scraping. A physical inner wall desilting device for large-diameter connecting pipes in water conservancy projects, including a pipe body and a slot; the pipe body is fixed with a fixed seat, and the fixed seat is rotatably connected with a nozzle seat, and the rotating shaft is fixed with a nozzle by bolts seat. Because the interval between the slots is equal to the blade width of the blade composed of blade A and blade B, when one slot position is moved, blade A and blade B move one blade position, so that scraping can be ensured. While improving the efficiency and avoiding missing scraping, the quick adjustment of the position of the crushing structure is realized.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning, and more specifically relates to a physical inner wall desilting device for large-diameter connecting pipelines in water conservancy projects. Background technique [0002] In water conservancy projects, all the pipes involved are large pipes with large diameters. Compared with municipal drainage pipes, the pipes are relatively large in diameter, and most of these pipes are used in the wild environment, lacking effective protection. Moreover, the liquid transported by the pipeline also has more impurities such as sand and soil in nature, and long-term use will cause more silt on the inner wall of the pipeline, which is difficult to clean. [0003] For example, the application number: CN201810888914.4, the present invention provides an automatic desilting device for the inner wall of a pipeline for water conservancy engineering, which relates to the technical field of pipeline cleaning f...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides a physical inner wall desilting device for large-diameter connecting pipelines in water conservancy projects to solve the existing problem that the existing device has a whole blade structure because of its scraper, and the entire scraper is in contact with the inner wall of the pipeline. , the resistance is large when scraping the sludge, and when adjusting the scraping position, it is impossible to quickly adjust the position of the crushing structure while ensuring the scraping efficiency and avoiding missing scraping; moreover, it is impossible to realize the clamp when fixing Synchronous and quick adjustment, and the problem that efficient anti-slip in the axial direction and front and rear cannot be achieved after fixing
