Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pipeline leak sealing device. Background Technology

[0002] Pipeline leaks in water conservancy projects can lead to significant water loss, wasting water resources and potentially polluting the surrounding environment. For example, leaks in sewage pipes can discharge wastewater into the soil or groundwater, polluting water sources and disrupting the ecological balance. Furthermore, leaks can reduce water pressure and flow in the pipeline system, affecting water supply and drainage efficiency. Sealing leaks helps restore the system to normal operation and ensures the efficient functioning of water conservancy facilities.

[0003] In existing technologies, when dealing with high-pressure pipeline leaks, traditional mechanical sealing methods, if performed directly without depressurization, may lead to uncontrollable water flow due to the high-pressure environment, thus posing a danger. For example, high pressure may cause water jetting, resulting in personal injury or equipment damage. Therefore, we propose a pipeline sealing device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pipe sealing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe sealing device includes a base plate. Two mating sleeves are fixedly connected to the top of the base plate. Threaded rods are threaded onto the inner walls of both mating sleeves. A top plate is slidably fitted onto the outer walls of the two threaded rods. Locking caps are threaded onto the outer walls of both threaded rods. Arc-shaped support plates are fixedly connected to the top of the base plate and the bottom of the top plate. Rubber plugging pads are fixedly connected to the outer walls of the two arc-shaped support plates. A pipe body is placed between the two rubber plugging pads. An installation hole is provided at the top of the top plate. A pressure relief pipe is welded to the inner wall of the installation hole. A ball is rotatably connected inside the pressure relief pipe. A T-shaped valve stem is fixedly connected to the outer wall of the ball. A pressure relief mechanism is provided inside the pressure relief pipe.

[0007] Preferably, the pressure relief mechanism includes a drive rod, a connecting seat is fitted on the outer wall of the T-shaped valve stem, the outer wall of the connecting seat is fixedly connected to the outer wall of the pressure relief pipe, a pressure relief hole is opened on the outer wall of the sphere, the outer wall of the sphere is fixedly connected to one end of the drive rod, and a rubber sleeve is fitted on the outer wall of both the drive rod and the T-shaped valve stem, the outer wall of the rubber sleeve is fixedly connected to the inner wall of the pressure relief pipe. By setting up the pressure relief mechanism, pressure relief is performed during the leak sealing process.

[0008] Preferably, the bottom of both locking caps is pressed against the top of the top plate, and the bottom plate and the top plate are fixed to the pipe body by setting the locking caps.

[0009] Preferably, the inner wall of the pressure relief pipe is threaded with a rubber plug. By setting the rubber plug, after the leak is plugged, debris is prevented from entering the pressure relief pipe, thus playing a protective role.

[0010] Preferably, the outer wall of the pressure relief pipe has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the T-shaped valve stem. The T-shaped valve stem is used to increase the stability of the ball rotation.

[0011] Preferably, the outer wall of the pressure relief pipe has a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the drive rod. By setting the drive rod, the ball is driven to rotate, thereby changing the position of the pressure relief hole.

[0012] Preferably, the outer wall of the rubber sleeve is slidably connected to the outer wall of the sphere.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution, by setting up a base plate, connecting sleeve, threaded rod, top plate, locking cap, arc-shaped support plate, and rubber plug, facilitates the fitting of the base plate and top plate onto the pipe body and ensures that the rubber plug is positioned on the pipe body. By setting up a pressure relief pipe, rubber plug, ball, T-shaped valve stem, connecting seat, pressure relief hole, drive rod, and rubber sleeve, pressure relief is achieved through the pressure relief pipe when fixing the position of the rubber plug, preventing water spray and thus avoiding personal injury or equipment damage.

[0023] Depend on Figures 1-4 As shown, a pipe sealing device is disclosed, including a base plate 1. Two mating sleeves 2 are fixedly connected to the top of the base plate 1. Threaded rods 3 are threadedly connected to the inner walls of the two mating sleeves 2. The two threaded rods 3 are detachably installed through the two mating sleeves 2. The same top plate 4 is slidably fitted onto the outer walls of the two threaded rods 3. The top plate 4 and the base plate 1 are mated and installed through the two threaded rods 3.

[0024] Both threaded rods 3 have locking caps 5 threaded onto their outer walls. The bottoms of both locking caps 5 press against the top of the top plate 4, fixing the top plate 4 to the pipe body 8. Both the top of the bottom plate 1 and the bottom of the top plate 4 are fixedly connected to arc-shaped support plates 6. Both arc-shaped support plates 6 have rubber plugging pads 7 fixedly connected to their outer walls, supporting the rubber plugging pads 7. The pipe body 8 is placed between the two rubber plugging pads 7, and the rubber plugging pads 7 seal the leak.

[0025] The top plate 4 has an installation hole at its top. A pressure relief pipe 9 is welded to the inner wall of the installation hole. A rubber plug 10 is threaded to the inner wall of the pressure relief pipe 9. The rubber plug 10 covers the top of the pressure relief pipe 9. A ball 11 is rotatably connected inside the pressure relief pipe 9. A T-shaped valve stem 12 is fixedly connected to the outer wall of the ball 11. The T-shaped valve stem 12 assists the ball 11 to rotate stably. A through hole is opened on the outer wall of the pressure relief pipe 9. The inner wall of the through hole is rotatably connected to the outer wall of the T-shaped valve stem 12.

[0026] The pressure relief pipe 9 is equipped with a pressure relief mechanism, which includes a drive rod 15. The outer wall of the drive rod 15 is provided with anti-slip texture. The outer wall of the pressure relief pipe 9 is provided with a circular hole. The inner wall of the circular hole is rotatably connected to the outer wall of the drive rod 15. The inner wall of the circular hole is sealed. The outer wall of the T-shaped valve stem 12 is fitted with a connecting seat 13. The outer wall of the connecting seat 13 is fixedly connected to the outer wall of the pressure relief pipe 9. The connecting seat 13 assists the T-shaped valve stem 12 to rotate.

[0027] The outer wall of the sphere 11 is provided with a pressure relief hole 14. When the pressure relief hole 14 is perpendicular to the axis of the pressure relief pipe 9, the water is blocked by the sphere 11. The outer wall of the sphere 11 is fixedly connected to one end of the drive rod 15. The outer walls of the drive rod 15 and the T-shaped valve stem 12 are both fitted with rubber sleeves 16. The outer wall of the rubber sleeve 16 is fixedly connected to the inner wall of the pressure relief pipe 9. The rubber sleeve 16 increases the sealing between the sphere 11 and the pressure relief pipe 9. The outer wall of the rubber sleeve 16 is slidably connected to the outer wall of the sphere 11.

[0028] Working principle: In use, the base plate 1 and two threaded rods 3 are fitted onto the pipe body 8, and then the top plate 4 is slid in through the two threaded rods 3. The two locking caps 5 are rotated to mate the top plate 4 with the base plate 1, securing the two arc-shaped support plates 6 and two rubber plugs 7 onto the pipe body 8. The rubber plug 10 is rotated to open the top of the pressure relief pipe 9. The top plate 4 and base plate 1 are moved on the pipe body 8, so that the rubber plug 7 on the top plate 4 is positioned at the leak location. At this point, the water at the leak location flows out along the pressure relief pipe 9. The rotation continues... The two locking caps 5 are moved to completely fix the bottom plate 1 and the top plate 4 to the pipe body 8, so that the rubber plug 7 located at the leak position squeezes the edge of the leak position. The drive rod 15 is rotated to make the ball 11 rotate. After the ball 11 rotates, it drives the pressure relief hole 14 to rotate. When the pressure relief hole 14 is perpendicular to the axis of the pressure relief pipe 9, the water is blocked by the ball 11 and cannot continue to flow out. After the rubber plug 7 is squeezed to the leak position in advance, the water cannot leak along the pipe wall, thus completing the sealing of the pipe body 8.
