Anti-blockage anti-hole-shrinkage sewage pipeline connecting device

Abstract

The invention discloses an anti-blockage anti-hole-shrinkage sewage pipeline connecting device, and relates to the technical field of sewage. The connecting device comprises a connecting pipe, evenlydistributed first springs are fixedly connected to the inner wall of the connecting pipe, clamping blocks are fixedly connected to the inner sides of the first springs, and two symmetric air grooves are formed in the inner walls of the connecting pipe. According to the anti-blockage anti-hole-shrinkage sewage pipeline connecting device, through cooperative use of an anti-blockage sleeve and an anti-blockage groove, when a pipeline is in threaded connection with the connecting pipe, a piston rod is extruded to move towards the interior of an air groove by a pipeline, the piston rod is extrudedby gas in the air groove, an anti-blockage sleeve expands under the effect of air pressure, the anti-blockage sleeve and the anti-blockage groove are clamped together, meanwhile, a clamping block is clamped with a clamping groove, the pipeline can be effectively prevented from loosening, the pipeline and the connecting pipe are tightly connected, slopes are arranged on the two ends of an inner pipe, sewage can conveniently pass through, the anti-blockage effect is achieved, the blockage possibility can be effectively reduced, and sewage conveying can be facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to an anti-clogging and anti-shrinkage sewage pipe connecting device. Background technique [0002] Sewage is often produced in daily life. At present, most of the sewage is transported to the collection place through sewage pipes, which is convenient for centralized treatment of sewage. Therefore, sewage pipes play a vital role in the process of sewage transportation. [0003] When the current sewage pipeline is in use, the connecting device is to fix the pipe on the outside, resulting in a decrease in the diameter of the pipe after a period of use, resulting in insufficient tightness between the pipe and the connecting device, resulting in sewage leakage, and the current pipeline There are often bulges at the joints, and the sewage contains other solid waste, which often leads to blockage of pipes, which affects the transportation of sewage, affects the environment, and affects the...
