Therefore, those skilled in the art provide a pipeline wall leakage hole sealing device to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0045] By adopting the above technical solution, the buckle can improve the portability of the arc-shaped sealing plate, making it more convenient to carry.

[0046] Working principle: When the invention is used, the arc-shaped sealing plate 2 is first placed at the leakage hole on the side wall of the pipeline body 1, and then the fixing rope 10 is pulled around the bottom end of the pipeline body 1. At this time, the connector 901 is screwed onto the connecting sleeve 8, which makes the fixing rope 10 wrap around the outside of the pipeline body 1. Then the staff can directly pull the pull ring 14 to tighten the fixing rope 10, and then put the pull ring 14 on the fixing hook 703 to limit and fix the fixing rope 10, so that the arc-shaped sealing plate 2 can be closely attached to the pipeline body 1 to preliminarily block the leakage hole on the side wall of the pipeline body 1. The whole operation process is simple and convenient. Then the staff presses and squeezes the airbag 403 to inflate the sealing airbag 401 through the connecting pipe 402, so that the sealing airbag 401 gradually expands and deforms to further block the leakage hole on the pipeline body 1, thereby achieving a better blocking effect on the leakage hole on the side wall of the pipeline body 1.

[0047] In the process of plugging pipes of different sizes, the use position of the slider 702 on the guide plate 701 can be adjusted by the positioning bolt 12, so that the position of the fixing hook 703 can be adjusted, thereby still facilitating the limiting fixation of the fixing rope 10, and further making it easy to fix the arc-shaped sealing plate 2 on pipe bodies 1 of different sizes for plugging work.
