Air-pressure dredging device

Abstract

The invention discloses an air-pressure dredging device which comprises air-pressure series and pipe control series components. Air which is pressurized by an inflator arranged in an air bottle shell can flow into an air bag via an air pipe and a skin pipe, and the air bag is communicated with an air pressure gauge, an air valve, an air valve connector, a connecting cap, a hose and an expansion pipe via the air pipe; a flared pipe head is arranged at the lower end of the expansion pipe, and the expansion pipe penetrates a fixing pipe to be connected with a rubber pipe; the upper end of the expansion pipe is closed, is provided with a push-pull rod and is connected with a spiral pipe; the spiral pipe is connected with the upper end of the fixing pipe in a threaded manner. The air-pressure dredging device has the advantages that the push-pull rod and the flared pipe head of the expansion pipe can be driven by the spiral pipe to ascend when a rotary handle upwardly rotates, accordingly, the rubber pipe and sewer pipeline openings can be squeezed to be sealed, standard air-pressure impact force can be kept, and sewer pipelines can be effectively dredged.

Description

technical field [0001] The invention relates to an indoor sewer pipe dredging tool, in particular to a pneumatic dredging device. technical background [0002] The clogging of indoor sewer pipes is mainly caused by the accumulation of some waste residues. At present, the use of wire rods and water suction to dredge the sewer pipes is not effective. Once the pipeline is a little longer and has many turns, there is nothing that can be done, and the purpose of dredging the sewer pipes cannot be achieved. SUMMARY OF THE INVENTION [0003] The invention provides a pneumatic dredging device with simple structure, convenient use, safe and reliable dredging of sewer pipes. [0004] In order to achieve the above-mentioned point, an air pressure dredging device is composed of air pressure series components: air valve, air valve joint, air valve handle, air pipe, air bottle cap, air support, chicken skin tube, air plug, air cylinder, air cylinder shell, air pump. Rod, gas cylinder n...

Problems solved by technology

[0002] The blockage of indoor sewer pipes is mainly caused by the accumulation of some waste residues. Now the effect of using steel wire scoops and water suction to dredge the sewer pipes is not good. Once the pipeline is longer and there are many turns, there is nothing to do, and the purpose of dredging the sewer pipes cannot be achieved.
