[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown, a pipe repair and sealing device for sewage treatment includes a sewage pipe 1. A fixed circular plate 2 is snapped onto the right side of the sewage pipe 1. Handles 3 are fixedly connected to the upper and lower parts of the right side of the fixed circular plate 2. A sealing component 4 is threadedly connected to the inner cavity of the center part of the fixed circular plate 2 and the sealing component 4 is located between the two handles 3. An auxiliary fixing component 5 is fixedly connected to the right side of the sealing component 4 and the auxiliary fixing component 5 is located to the right of the handles 3.

[0026] First, insert the left end of the sealing component 4 into the sewage pipe 1. Then, inject gas into the sealing component 4 using a micro air pump, which will cause the left end of the sealing component 4 to expand and seal the sewage pipe 1. Finally, with the help of the auxiliary fixing component 5, the sealing component 4 can be sealed, which will facilitate the maintenance of the sewage pipe 1.

[0027] like Figure 2 As shown, a sealing ring 21 is fixedly connected to the left side of the fixed circular plate 2 and the sealing ring 21 is located outside the fixed sleeve 41. The left side of the sealing ring 21 overlaps with the right side of the sewage pipe 1.

[0028] The sealing ring 21 provides a certain degree of protection between the fixed circular plate 2 and the sewage pipe 1, thus also serving as a seal.

[0029] A protective plate 45 is fixedly connected to the left side of the fixed column 43, and the right side of the protective plate 45 overlaps with the left side of the airbag 44.

[0030] The protective plate 45 provides some protection for the fixed column 43 when it pushes the airbag 44 into the sewage pipe 1.

[0031] like Figure 3 As shown, the sealing assembly 4 includes a fixed sleeve 41, the right side of which is fixedly connected to the left side of the fixed circular plate 2. A threaded rod 42 is threadedly connected to the inner wall of the fixed sleeve 41 and the fixed circular plate 2. A fixed post 43 is fixedly connected to the left side of the threaded rod 42 and is located to the left of the fixed sleeve 41. An airbag 44 is fixedly connected to the outer wall of the fixed post 43, and the outer wall of the airbag 44 overlaps with the inner wall of the sewage pipe 1. An air supply pipe 46 is fixedly connected to the inner cavity of the threaded rod 42, and the outer wall of the left part of the air supply pipe 46 is fixedly connected to the inner cavity of the fixed post 43 and the airbag 44 respectively.

[0032] By fixing the circular plate 2, the fixing column 43 and the airbag 44 can enter the interior of the sewage pipe 1. Then, by rotating the fixing shell 51 and the threaded rod 42, the threaded rod 42 can move to the left under the action of the fixing sleeve 41, so that the fixing column 43 can drive the airbag 44 to move to the left. Thus, the position of the airbag 44 can be adjusted according to the sealing requirements during use. Then, by using the action of the micro air pump, air can enter the interior of the airbag 44 through the connecting hose 52 and the air supply pipe 46, so that the airbag 44 expands to the inner wall of the sewage pipe 1, thereby sealing the sewage pipe 1.

[0033] like Figure 4As shown, the auxiliary fixing component 5 includes a fixing shell 51. The left side of the fixing shell 51 is fixedly connected to the right side of the threaded rod 42. The right side of the air supply pipe 46 is fixedly connected to a connecting hose 52. The right side of the connecting hose 52 is fixedly connected to an air inlet 53. The outer walls of the opposite parts of the air inlet 53 and the air supply pipe 46 are fixedly connected to the inner cavities of the left and right parts of the fixing shell 51, respectively. The outer wall of the middle part of the connecting hose 52 is snapped with a support base 54. The lower surface of the support base 54 is fixedly connected to the bottom of the inner cavity of the fixing shell 51. The outer wall of the upper valve of the support base 54 is movably sleeved with a limiting pressure block 55, and the limiting pressure block 55 is located above the connecting hose 52. The upper surface of the limiting pressure block 55 is rotatably connected to a threaded rod 56. The outer wall of the threaded rod 56 is threadedly connected to the inner cavity of the fixing shell 51. The upper surface of the threaded rod 56 is fixedly connected to a rotating wheel 57, and the rotating wheel 57 is located above the fixing shell 51.

[0034] By rotating the wheel 57, the threaded rod 56 can rotate downward, thereby allowing the limiting block 55 to move horizontally downward under the restriction of the guide rod 58. At this time, with the cooperation of the support base 54, the connecting hose 52 between the support base 54 and the limiting block 55 can be squeezed, thereby sealing the airbag 44. When disassembly is required, simply rotate the wheel 57 and the threaded rod 56 in the opposite direction, thus facilitating sealing, fixing, and disassembly during use.

[0035] like Figure 5 As shown, the inner cavities of the front and rear parts of the limiting pressure block 55 are slidably connected to two guide rods 58, and the four guide rods 58 are located on the front and rear sides of the support base 54 respectively. The lower surfaces of the four guide rods 58 are fixedly connected to the bottom of the inner cavity of the fixed shell 51 respectively.

[0036] The guide rod 58 enables the limiting block 55 to move stably up and down within the cavity of the fixed shell 51, thereby playing a guiding role.

[0037] The working principle of this utility model is as follows: First, the fixed circular plate 2 allows the fixed column 43 and the airbag 44 to enter the sewage pipe 1. Then, by rotating the fixed shell 51 and the threaded rod 42, the threaded rod 42 moves to the left under the action of the fixed sleeve 41, thereby allowing the fixed column 43 to drive the airbag 44 to move to the left. Thus, the position of the airbag 44 can be adjusted according to the sealing requirements during use. Then, by using the action of the micro air pump, air can enter the airbag 44 through the connecting hose 52 and the air supply pipe 46, causing the airbag 44 to expand to the inner wall of the sewage pipe 1, thereby sealing the sewage pipe 1. Next, by rotating the rotating wheel 57, the threaded rod 56 can rotate downward, thereby allowing the limiting pressure block 55 to move horizontally downward under the restriction of the guide rod 58. At this time, with the cooperation of the support base 54, the connecting hose 52 between the support base 54 and the limiting pressure block 55 can be squeezed, thereby sealing the airbag 44. When disassembly is required, simply rotate the rotating wheel 57 and the threaded rod 56 in the opposite direction.
