Pipeline interior flushing device for underground pipeline construction

Abstract

The invention provides an underground pipeline construction pipeline interior flushing device, and relates to the technical field of flushing devices.The underground pipeline construction pipeline interior flushing device comprises a water pipe mounting barrel, a first connecting ring and a second connecting ring are rotationally mounted on the water pipe mounting barrel, a connecting rod assembly is arranged between the first connecting ring and the second connecting ring, and the connecting rod assembly comprises a connecting rod and a sliding rod; the two ends of the sliding rod are slidably installed in the sliding grooves, a fixing assembly is arranged at the lower end of the connecting rod and comprises a first half ring and a second half ring, the inner wall of the first half ring and the inner wall of the second half ring abut against the periphery of the water pipe, and a bottom block is fixedly installed on the lower surface of the second half ring. The surface of one side of the bottom block abuts against the clamping block. The connecting rod on the connecting rod assembly is controlled to move, so that the connecting rod is in an ideal bent state, the bent position of a pipeline can be better cleaned, the effect of going deep into the bent position of the pipeline is better achieved, the cleaning process is easier, and the drainage efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flushing devices, in particular, to an internal flushing device for underground pipeline construction pipelines. Background technique [0002] Due to its unique characteristics, pipes are widely used in many industries and fields. Pipes are widely used, mainly used in water supply, drainage, agricultural irrigation and various environmental protection devices. When the rainwater is heavy, the sludge adsorption residue inside the pipeline is easy to cause water accumulation. The use of underground natural drainage is easy to cause drainage failure due to the blockage of sludge, resulting in the backflow of accumulated water, affecting road traffic, and bringing inconvenience to people's daily life. It seriously threatens people's safe travel, and also has a certain impact on the environmental protection industry. [0003] For example, the application number: CN201920498907.3 provides an underground pipel...

Problems solved by technology

[0006] Aiming at the inability of the existing technology to go deep into the bend of the pipeline, it is not easy to clean the bend of the pipeline, resulting in a large amount of sludge and impurities adhering to the inner wall of the bend of the pipeline, and the residue of impurities in the pipeline will seriously affect the drainage efficiency. The invention provides an internal flushing device for underground pipeline construction
