[0028] Working principle:

[0029] When blocking the rainwater and sewage pipes:

[0030] Assembly process:

[0031] The operator rotates and removes the first bolts 9 on both sides, removes the protective plate 10, fits the mounting plate 4 with the inner surface of the outer shell 1, inserts the blocking airbag 5 into the inner surface of the outer shell 1 through the opening on the surface of the outer shell 1, fixes the blocking airbag 5 to the surface of the mounting plate 4, and then installs the mounting plate 4 to the surface of the outer shell 1 through two second bolts 3, so that the blocking airbag 5 can be fixed with the surface of the cylinder 8 to prevent air leakage.

[0032] Fixation process:

[0033] After the operator places the outer shell 1 at a suitable position inside the rainwater and sewage pipe, the operator rotates the hexagonal block 706 with a tool such as a wrench, so that the hexagonal block 706 can drive the stud 702 to rotate synchronously, so that the stud 706 can drive the threaded blocks 703 on both sides to move synchronously to both sides, so that the threaded blocks 703 on both sides can drive the push rods 705 on both sides to move synchronously, and the push rods 706 on both sides push the slides 704 and the rubber plate 6 on both sides to press against the inner wall of the rainwater and sewage pipe, so that the position of the outer shell 1 is fixed.

[0034] Blocking process:

[0035] The operator pushes and pulls the rod 202 back and forth through the semicircular block 201, so that the rod 202 can drive the piston 204 to move synchronously. When the piston 204 is pulled outward, the cushions 205 on both sides can be opened under the action of air pressure, so that the outside air can enter the other side of the piston 204. When the piston 204 is pushed, the two cushions 205 are closed under the action of the internal air pressure. At the same time, the air pressure inside the cylinder 8 can be increased under the push of the piston 204, so that the rubber block 20 6 is pushed, so that the rubber block 206 can compress the spring 209 through the straight rod 207, so that the rubber block 206 is no longer pressed against the surface of the groove ring 11, so that the gas can enter the inside of the blocking airbag 5, and the blocking airbag 5 is inflated to a state of pressing against the inner wall of the rain and sewage pipe by reciprocatingly pushing and pulling the piston 204, thereby completing the function of blocking the rain and sewage pipe. At the same time, the gas inside the blocking airbag 5 can push the rubber block 206 to press against the surface of the groove ring 11, so that the gas inside the blocking airbag 5 will not leak.
