In an environment with or without water, the airbag is manually carried into the pipeline for plugging. First, the construction waste and silt in the plugging area are cleared by hands. Then, the personnel on the ground put the airbag into the well, and the diver pushes the airbag into the plugging area at the drainage pipeline opening. The diver returns to the ground, and the air compressor inflates the airbag to achieve plugging. Because the drainage pipeline is filled with sewage and contains a large amount of combustible, explosive, and toxic gases, personal injury accidents often occur.

The plugging component includes a type pushing mechanism connected to the bottom of the rack and with the pushing direction perpendicular to the moving direction of the rack, a lidar arranged at the bottom of the type pushing mechanism, and a plugging airbag arranged at the end of the type pushing mechanism. The power and control component receives the signal transmitted by the lidar and controls the driving motor to act and controls the inflation or air supplement of the plugging airbag. This kind of municipal pipeline airbag automatic plugging system and method can realize underwater unmanned intelligent plugging without underwater manual operation. However, in the prior art, the airbag is located at the end of the plugging component.

When the pushing cylinder 512 drives downward, assisted by the guidance of the pushing guide rod 513, it drives the multi-stage pushing and releasing guide block 514 to push the airbag 600 downward. When the airbag 600 is pushed down to the airbag guiding assembly 520, the multi-stage pushing and releasing guide block 514 can adapt to the bending guiding path of the airbag guiding assembly 520 and push the airbag 600 downward.

The guiding cylinder 521 pulls the guiding cable 524, capable of adjusting the turning angle of a plurality of guiding block hinges 522. Under normal conditions, the braking device 523 is in a locked state, and a plurality of guiding block hinges 522 are in a straight line state. When turning is required, the braking device 523 is opened, and the guiding cylinder 521 pulls the guiding cable 524 to turn a plurality of guiding block hinges 522. When the plurality of guiding block hinges 522 are adjusted to a suitable turning angle, the guiding cylinder 521 stops pulling the guiding cable 524. At this time, the braking device 523 is started again to be in a locked state, maintaining the adjusted turning angle of the plurality of guiding block hinges 522.

Open the pneumatic device to inflate the airbag 600 to plug the pipeline. When the inflation reaches the specified pressure, close the pneumatic device. Regularly check the data of the pressure gauge. When the pressure drops, inflate in time to achieve effective plugging. When plugging is not required, disconnect the airbag 600 through the quick-change joint and the air pipe. The airbag 600 leaks air, and the airbag 600 is recovered from the horizontal shaft 720 through the airbag lifting mechanism 611.
