Embodiment

[0035] as attached figure 1 to attach Figure 9 Shown:

[0036] The invention provides a physical inner wall desilting device for large-diameter connecting pipelines in water conservancy projects, which includes a pipe body 1 and a slot 301; a fixing seat 2 is fixed on the pipe body 1, and a rotating shaft 3 is rotatably connected to the fixing seat 2, and the rotating shaft 3 is fixed with a nozzle seat 4 by bolts; the rotating shaft 3 is fixed with a crushing structure 5 by bolts, and the rotating shaft 3 is also fixed with a cleaning structure 6 by bolts; refer to Figure 7 , the distance between the slots 301 is equal to the blade width of the scraper composed of the blade A504 and the blade B505, and when the slot 301 is moved, the blade A504 and the blade B505 move a blade position, thereby ensuring Rapid adjustment of the position of the crushing structure 5 is realized while scraping efficiency and avoiding missed scraping; refer to Figure 7 , the cutter head A504 ...

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...
