Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pipelines, in particular to a self-cleaning slag water conservancy pipeline for water conservancy projects. Background Technique

[0002] When transporting water, due to residues and dirt in the water, it is easy to accumulate inside the pipeline, resulting in pipeline blockage. Traditionally, the inside of the pipeline and the water are cleaned manually, which wastes a lot of time and manpower and has low work efficiency.

[0003] A self-cleaning slag water conservancy pipeline for water conservancy projects is disclosed in the Chinese utility model CN216195249U. The self-cleaning slag water conservancy pipeline for water conservancy projects flushes the baffle through water flow, thereby driving the transmission shaft and the pulley to rotate, and then driving the turntable to rotate. Through the mutual cooperation of the turntable, the first connecting rod, the second connecting rod, the limiting ring and the U-shaped connecting rod, the scraper can be moved, and then the residues on the surface of the filter screen are cleaned by the scraper, so that the residues in the pipeline and the water can be cleaned, saving the subsequent manual cleaning process and improving the work efficiency. However, the self-cleaning slag water conservancy pipeline for water conservancy projects still has the following problems in use:

[0004] The self-cleaning slag water conservancy pipeline for water conservancy projects drives the scraper to slide back and forth through the transmission structure to push the garbage on the filter screen out. When the scraper is pushed downward, the impurities on the surface will be pushed to the bottom of the filter screen, resulting in its inability to be pushed out again, leading to garbage accumulation. Moreover, the resistance of the reciprocating sliding is large, and a large water flow impact on the baffle is required to drive the transmission shaft to rotate to drive the scraper. Therefore, the practicability is not good. Summary of the Utility Model
