[0002] The pipe plugging airbag is a special tool used for pipeline maintenance, detection or blocking water flow. It is particularly suitable for non-excavation repair or temporary plugging operations of water supply and drainage pipes, sewage pipes, oil and gas pipelines, etc.
[0003] The existing pipeline plugging airbag is placed in the pipeline to be blocked, and the airbag is expanded to fill the entire pipeline cross-section to block the pipeline. However, since there may be sharp objects such as stones and glass in the pipeline, the airbag is easily damaged. In addition, the airbag blocks water leakage through the friction between the airbag and the pipeline, and has poor stability and is easily detached from the pipeline, which is relatively inconvenient.
[0004] Therefore, a bladder-type pipeline pressure-sealing device has been developed, which can clean the inner wall of the pipeline to prevent the airbag from being damaged, and can enhance the stability between the airbag and the pipeline to prevent the airbag from being separated from the pipeline. Utility Model Content

The utility model provides a bladder-type structure pipeline pressure blocking device that can clean the inner wall of the pipeline to avoid damage to the airbag, and can enhance the stability between the airbag and the pipeline to avoid detachment of the airbag from the pipeline.
[0006] The technical solution is: a bag-type structure pipeline pressure sealing device, including an airbag, a connecting pipe, a pressurized pipe, a valve, a joint, a cleaning component and a stabilizing component. The airbag is connected to the left side of the middle part with a connecting pipe, the left side of the front part of the connecting pipe is connected to the pressurized pipe, the front side of the pressurized pipe is rotatably connected with a valve, the left side of the pressurized pipe is connected to a joint, the airbag is provided with a cleaning component capable of cleaning the inner wall of the pipe, and the airbag is also provided with a stabilizing component capable of enhancing stability on the pipe.
[0007] Furthermore, a pressure gauge is also included, and the pressure gauge is connected to the left side of the rear portion of the pipe.
[0008] Furthermore, the cleaning component includes a fixing ring, a frame and a rubber ring. The left and right sides of the airbag are connected to the fixing ring, the sides of the fixing rings away from each other are connected to the frame, and the frames are connected to the rubber ring.
[0009] Furthermore, the rubber rings are all provided with ventilation grooves.
[0010] Furthermore, the stabilizing assembly includes a fixed rod, a rotating rod, a torsion spring, an anti-skid pad, a pull rope and a hanging particle. The left part of the airbag is connected to multiple fixed rods, each of the fixed rods is rotatably connected to a rotating rod, each of the rotating rods is connected to the connected fixed rods with multiple torsion springs, each of the rotating rods is connected to an anti-skid pad, a pull rope is wrapped between the anti-skid pads, and a hanging particle is provided between the front and rear parts of the pull rope.
[0011] Furthermore, the anti-skid pads are provided with anti-skid patterns.
[0012] The beneficial effects of the utility model are as follows: the utility model moves the rubber ring in the pipeline, and then tightens the pull rope through the hanging particles, so that the rotating rod rotates inward on the fixed rod, and the torsion spring is deformed until the anti-slip pad contacts the outer wall of the pipeline, thereby achieving the effect of cleaning the inner wall of the pipeline and avoiding damage to the airbag, and enhancing the stability between the airbag and the pipeline, avoiding the airbag from being detached from the pipeline.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.
[0018] A bladder-type pipeline pressure plugging device, such as Figure 1-Figure 3 As shown, it includes an airbag 1, a connecting pipe 5, a pressure gauge 6, a pressurizing pipe 7, a valve 8, a connector 9, a cleaning component and a stabilizing component. The connecting pipe 5 is connected to the left side of the middle of the airbag 1, the pressure gauge 6 is connected to the left side of the rear of the connecting pipe 5, the pressurizing pipe 7 is connected to the left side of the front of the connecting pipe 5, the valve 8 is rotatably connected to the front side of the pressurizing pipe 7, and the connector 9 is connected to the left side of the pressurizing pipe 7. The airbag 1 is provided with a cleaning component, and the airbag 1 is also provided with a stabilizing component.
[0019] like Figure 1-Figure 3As shown, the cleaning assembly includes a fixing ring 2, a rack 3 and a rubber ring 4. The fixing rings 2 are connected to the left and right sides of the airbag 1, the racks 3 are connected to the sides of the fixing rings 2 that are away from each other, the racks 3 are connected to the rubber rings 4, and the rubber rings 4 are provided with air-permeable grooves for easy pushing into the pipeline.
[0020] like Figure 1 and Figure 3 As shown, the stabilizing assembly includes a fixed rod 10, a rotating rod 11, a torsion spring 12, an anti-skid pad 13, a pull rope 14 and a hanging particle 15. Eight fixed rods 10 are connected to the left part of the airbag 1. The fixed rods 10 are rotatably connected to the rotating rods 11. Two torsion springs 12 are connected between the rotating rods 11 and the connected fixed rods 10. The rotating rods 11 are connected to the anti-skid pads 13. The anti-skid pads 13 are provided with anti-skid patterns to prevent slipping. Pull ropes 14 are wrapped around the anti-skid pads 13. A hanging particle 15 is provided between the front and rear parts of the pull ropes 14.
[0021] When using the utility model, first connect the air pump air pipe with the pressure pipe 7 through the joint 9, then open the pipe port, slowly place the right end of the airbag 1 at the desired position from this port, fix the frame 3 with the fixing ring 2, so that the rubber ring 4 moves in the pipe to clean the inner wall of the pipe. After the airbag 1 reaches the specified position, turn and open the valve 8, so that the pressure pipe 7 inflates the airbag 1 through the connecting pipe 5, so that the airbag 1 expands and blocks the pipe. The pressure gauge 6 detects the pressure in the airbag 1 to avoid excessive pressure in the airbag 1. After the airbag 1 expands and blocks the pipe, the hanging pellet 1 can be used to The pull rope 14 is tightened to make the rotating rod 11 rotate inward on the fixed rod 10, and the torsion spring 12 is deformed until the anti-skid pad 13 contacts the outer wall of the pipeline, so as to clean the inner wall of the pipeline and prevent the airbag 1 from being damaged, and to enhance the stability between the airbag 1 and the pipeline and prevent the airbag 1 from being separated from the pipeline. When the airbag 1 needs to be removed, the pull rope 14 is loosened by the hanging particle 15, and then restored by the torsion spring 12, so that the rotating rod 11 is reset, so that the anti-skid pad 13 no longer contacts the outer wall of the pipeline, and then the airbag 1 is recovered and taken out of the pipeline.
