[0012] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, a pipeline plugging device comprises a water pipe 1, and the output end of the water pipe 1 is fixedly connected with a rotating nozzle 2, through which the pipeline can be rotated and flushed.

[0013] One of the pipeline plugging devices also includes a multiple plugging component 3, and the multiple plugging component 3 is integrally connected to the outer wall of the water pipe 1; the multiple plugging component 3 can be used to perform multiple plugging of the pipeline, which is conducive to achieving the effect of multiple plugging of the pipeline, and can effectively avoid the problem of the plugging device losing its plugging function during the construction process, thereby avoiding the problem of safety accidents.

[0014] Among them, the multiple blocking components 3 include blocking airbags 31 arranged in sequence from left to right, and the upper internal openings between the blocking airbags 31 are laterally integrated with an inflation tube 32, and the upper openings of the inflation tube 32 are integrated with a first one-way valve 34 in sequence from left to right, wherein the first one-way valve 34 is respectively located inside the blocking airbags 31; the lower internal openings between the blocking airbags 31 are laterally integrated with an intake tube 33, and the lower openings of the intake tube 33 are integrated with a second one-way valve 35 in sequence from left to right, wherein the second one-way valve 35 is also respectively located inside the blocking airbags 31.

[0015] In the present embodiment, specifically, through holes are respectively opened on the left and right sides of the inner middle portion of the blocking airbag 31, and the blocking airbag 31 is integrally connected to the outer wall of the water pipe 1 in sequence from right to left through the through holes.

[0016] In this embodiment, specifically, the blocking airbag 31 is a rubber airbag.

[0017] In this embodiment, specifically, the inflation pipe 32 and the suction pipe 33 are respectively made of rubber tubes.

[0018] In this embodiment, specifically, the first one-way valve 34 and the second one-way valve 35 are both one-way valves with the lower end as the input end and the upper end as the output end.

[0019] In this embodiment, specifically, the water pipe 1 adopts an explosion-proof steel wire hose.

[0020] In this embodiment, specifically, the rotating nozzle 2 is a 360° stainless steel rotating nozzle.

[0021] When using the present blocking device, the operator can directly extend the blocking device into the blocked pipe, and then the operator can connect the output end of the external high-pressure water pump to the water pipe 1, and then the operator can turn on the high-pressure water pump, and the high-pressure water will be rotated and sprayed onto the inner wall of the pipe through the rotating nozzle 2, so as to rinse and clean the rust on the inner wall of the pipe, and avoid the problem of too much rust residue on the inner wall of the pipe. When the rust residue is cleaned, the operator can connect an air pump to each of the inflation pipe 32 and the suction pipe 33, and then the operator can turn on the air pump connected to the suction pipe 33, so that the air pressure inside the suction pipe 33 is always greater than the air pressure in the blocking airbag 31, thereby avoiding the problem of the air in the blocking airbag 31 entering the inside of the suction pipe 33 through the second one-way valve 35. Afterwards, the operator can turn on the air pump connected to the inflation tube 32, so that the air pump can fill air into the interior of the blocking airbag 31 through the inflation tube 32 and the first one-way valve 34 until the blocking airbag 31 is fully inflated and tightly attached to the inner wall of the pipeline, thereby completing the blocking of the pipeline. Because there are multiple blocking airbags 31 in the utility model, and because the air in the blocking airbag 31 cannot enter the inflation tube 32 through the first one-way valve 34, nor can it enter the suction tube 33 through the second one-way valve 35, when one of the blocking airbags 31 is damaged, the other blocking airbags 31 can all perform the blocking function, thereby achieving the effect of multiple blocking pipelines, which can effectively avoid the problem of the blocking device losing its blocking function during the construction process, and thus avoid the problem of safety accidents. When deflation is required, the operator can separate the suction pipe 33 from the air pump. At this time, the air pressure inside the suction pipe 33 is reduced, and the air in the blocking airbag 31 will enter the suction pipe 33 through the second one-way valve 35. Then the suction pipe 33 will discharge the air into the external atmosphere, thereby completing the deflation of the blocking airbag 31.

[0022] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
