Explosion-proof dredging device for high-tight domestic sewage pipelines with pneumatic deformation sealing

Abstract

The invention discloses an air pressure type deformation blocking sanitary sewer anti-explosion dredging device with high sealing performance. The device comprises an air storage mechanism, an air conveyor rod, a deformation blocking mechanism and a blocking control mechanism, wherein the air storage mechanism comprises a casing, an air storage tank, an anti-explosion mechanism, a first one-way valve, a storage battery, a controller, an air pump, a plurality of control buttons and a lug; the anti-explosion mechanism comprises an electromagnetic valve and a safety valve; the deformation blocking mechanism comprises a seal cover arranged at the lower end of the air conveyor rod, a sliding pressing plate and a deformation end cap; the deformation end cap comprises a deformation support frameand a rubber jacket arranged on the support frame in a sleeving manner; and the blocking control mechanism comprises a rotating rod, a traction rod and a pull rod. The air pressure type deformation blocking sanitary sewer anti-explosion dredging device with high sealing performance disclosed by the invention is reasonable in structure, and has the advantages of being simple in structure, convenient to use, high in intelligent degree, high in sealing performance, safe, reliable, and high in practicability, saving time and labor, and the like, so that the problem that existing air pressure typesewer dredging equipment is low in sealing performance is effectively solved.

Description

technical field [0001] The invention relates to the field of equipment for dredging sewage pipes, in particular to an explosion-proof device for dredging domestic sewage pipelines with air pressure deformation and high sealing performance. Background technique [0002] In the prior art, pipeline dredging methods mainly include spring steel wire dredging, pneumatic dredging and hydraulic dredging, etc., which can dredge pipelines under certain circumstances, but have the following problems: spring dredging is difficult to dredge in sharp turns, The labor intensity is high, and the spring is easy to damage the pipeline when it rotates forward; when using hydraulic dredging, the pressure is limited, and when there is no dredging, the water will easily overflow the pool and become full of water; the existing pneumatic dredger is difficult Dredging is not completely blocked. The reason is that the existing pneumatic dredger uses a rubber bowl-shaped structure to seal. Due to the ...
