The left and right clamps are both fixedly installed on the pipeline and are located on the left and right sides of the leak point, respectively. An installation plate arranged along the pipeline axis is connected between the left and right clamps. The leak-sealing mechanism includes a sealing cover with an opening on the bottom surface covered by a fixedly installed rubber pad. An air bladder is installed inside the cavity of the sealing cover. The sealing cover is connected to the installation plate through a guide mechanism. A pressure-applying mechanism is provided on the installation plate to press the sealing cover tightly against the outer wall of the pipeline.

[0006] Preferably, an inflation nozzle is installed on the airbag, and a through hole for the inflation nozzle to extend from the top surface of the sealing cover is provided. Air can be added to the airbag by connecting the inflation nozzle to an air pump or similar device, causing the airbag to inflate.

[0007] Preferably, the pressure applying mechanism includes a tightening screw, which is rotatably connected to the mounting plate. A handle is connected to the upper end of the tightening screw. Rotating the tightening screw to move it downward can tighten the sealing cover.

[0008] Preferably, the guiding mechanism includes two guide rods, which are located on the left and right sides of the tightening screw, respectively. The lower end of each guide rod is fixedly connected to the sealing cover, and each guide rod passes through the mounting plate. A limiting stop is fixedly connected to the upper end of each guide rod.

[0009] Preferably, connecting screws are fixedly connected to both the left and right clamps, and mounting holes are provided at both ends of the mounting plate. The connecting screws pass through the mounting holes, and a fixing nut for fixing the mounting plate is threaded onto each connecting screw.

[0010] Preferably, a sealing strip is provided around the lower edge of the sealing cover, and the sealing strip contacts the outer wall of the pipe to improve the sealing effect.

[0011] The beneficial effects of this utility model are as follows: This invention uses a sealing cover as the first sealing method and an inflatable bladder to press a rubber gasket tightly against the leak point as the second sealing method. The combination of these two sealing methods can effectively seal the leak point, thereby achieving a leak-stopping effect. It is easy to install and has good performance.

[0013] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0014] like Figure 1-2 As shown, this utility model includes a left clamp 1, a right clamp 2, and a leak-sealing mechanism. The left clamp 1 and right clamp 2 are both fixedly installed on the pipe 3, and are located on the left and right sides of the leak point 14, respectively. An installation plate 6, arranged axially along the pipe, connects the left clamp 1 and right clamp 2. The leak-sealing mechanism includes a sealing cover 10, with an opening on its bottom surface covered by a fixedly installed rubber pad 13. An airbag 11 is installed inside the cavity of the sealing cover 10. The sealing cover 10 is connected to the installation plate 6 via a guide mechanism. The installation plate 6 is provided with a pressure-applying mechanism for pressing the sealing cover 10 tightly against the outer wall of the pipe.

[0015] In this embodiment, an inflation nozzle 15 is installed on the airbag 11, and a through hole for the inflation nozzle 15 to extend out is provided on the top surface of the sealing cover 10. By connecting the inflation nozzle 15 to an air pump or similar device, air can be added to the airbag 11, causing the airbag 11 to inflate.

[0016] In this embodiment, the pressure applying mechanism includes a tightening screw 8, which is rotatably connected to the mounting plate 6. A handle 9 is connected to the upper end of the tightening screw 8. Rotating the tightening screw 8 to move it downward can tighten the sealing cover 10.

[0017] In this embodiment, the guiding mechanism includes two guide rods 7, which are located on the left and right sides of the tightening screw 8, respectively. The lower end of each guide rod 7 is fixedly connected to the sealing cover 10, and each guide rod 7 passes through the mounting plate 6. A limiting stop is fixedly connected to the upper end of each guide rod 7.

[0018] In this embodiment, connecting screws 4 are fixedly connected to both the left clamp 1 and the right clamp 2. Mounting holes are provided at both ends of the mounting plate 6. The connecting screws 4 pass through the mounting holes, and a fixing nut 5 for fixing the mounting plate 6 is threaded onto each connecting screw 4.

[0019] In this embodiment, a sealing strip 12 is provided around the lower edge of the sealing cover 10, and the sealing strip 12 contacts the outer wall of the pipe to improve the sealing effect.

[0020] In practical use, first fix the left clamp 1 and right clamp 2 onto the pipeline, and then fix the mounting plate 6 to the left clamp 1 and right clamp 2. Rotate the tightening screw 8 to move it down, and the tightening screw 8 can tighten the sealing cover 10 so that the sealing cover 10 is tightly against the outer wall of the pipeline. At this time, the leakage point 14 is covered by the rubber gasket 13 of the sealing cover 10. Inflate the airbag 11, and after the airbag 11 expands, it will make the rubber gasket 13 tightly adhere to the leakage point 14 to achieve leakage sealing.

[0021] This invention uses a sealing cover 10 as the first sealing method and an airbag 11 to inflate and press the rubber pad 13 against the leakage point 14 as the second sealing method. The combination of the two sealing methods can effectively seal the leakage point 14, thereby achieving the leak-stopping effect. It is easy to install and has good performance.
