[0045] Embodiment 1:

[0046] The present embodiment provides a plugging device based on a pressure pipe, comprising: an extrusion assembly, used to extrude and seal the ruptured part of the pipe; a connecting plate 1, installed on the extrusion assembly, provided with a plug-in port 7 and a locking assembly on the connecting plate 1, and provided with a driving assembly on the locking assembly; a plug-in plate 6, one end of which is fixedly connected to the extrusion assembly, and the other end is plugged and installed in the plug-in port 7 and cooperates with the locking assembly; wherein the driving assembly is used to drive the locking assembly to position the plug-in plate 6 so that the extrusion assembly can squeeze and seal the pipe. When the plugging device is used to seal the ruptured part of the pipe, it is only necessary to drive the locking assembly to cooperate with the plug-in plate 6 through the driving assembly to realize the compression or separation of the pipe by the extrusion assembly, which simplifies the operation steps, saves time and effort, and improves work efficiency. In the present embodiment, if Figure 1 and Figure 2 As shown, the locking assembly includes a driving cavity 9, which is located in the connecting plate 1. Positioning ports 10 are provided at both ends of the connecting plate 1 where the length is shorter. A connecting piece is provided inside the driving cavity 9. Both ends of the connecting piece are equipped with bearings and transmission nuts. On the one hand, the connecting piece is movably connected to the inner wall of the connecting plate 1 through the bearing, and on the other hand, the connecting piece is transmission-connected to the positioning block 13 through the transmission nut. At the same time, a connecting port 12 is provided at both ends of the driving cavity 9. A positioning port 11 is provided at one end of the plug-in plate 6 that is plugged in and out of the plug-in port 7. The width of the positioning block 13 is smaller than the width of the positioning port 11 and the connecting port 12, and the positioning port 11 is connected to the connecting port 12. The driving assembly is installed on the connecting piece. In the process of driving the connecting piece, the connecting piece drives the two positioning blocks 13 to move synchronously, and sequentially passes the positioning blocks 13 through the communication port 12 and the positioning port 11, and finally inserts them into the positioning port 10 to position the plug-in plate 6, so that the extrusion assembly can press the pipeline tightly, thereby plugging the rupture of the pipeline. Furthermore, if Figure 2-Figure 4 As shown, the driving assembly includes a driven gear 14 and a connecting rod 16. A rotating hole is opened at the top of the connecting plate 1. The end of the connecting rod 16 passes through the rotating hole and extends into the driving cavity 9 to be rotatably connected to the inner bottom surface of the driving cavity 9. The driven gear 14 is sleeved on the outside of the connecting member. A handle 15 and a driving gear 17 are installed on the connecting rod 16 from top to bottom, wherein the driving gear 17 is meshingly connected with the driven gear 14. In this embodiment, the connecting member is preferably a double-headed screw 8, the driven gear 14 is installed in the middle of the double-headed screw 8, the connecting rod 16 is located on one side of the double-headed screw 8, and is axially perpendicular to the double-headed screw 8. The handle 15 is installed on the top of the connecting rod 16 and is located outside the connecting plate 1. The driving gear 17 is installed in the middle of the connecting rod 16 and is meshingly connected with the driven gear 14. When the handle 15 is manually rotated forward or reversed, the two positioning blocks 13 move closer to or farther away from each other. In this embodiment, as Figure 1-Figure 2As shown, the extrusion assembly includes an upper extrusion block 2 and a lower extrusion block 4. Both the upper extrusion block 2 and the lower extrusion block 4 are structures with one end open and the other end closed, and their cross-sections are arc-shaped. Seals are installed on the inner sides of the open ends of the upper extrusion block 2 and the lower extrusion block 4. The seals are used to seal the ruptured parts of the pipeline. The connecting plate 1 is installed on the outer side of the blocked end of the upper extrusion block 2; connecting ears 5 are provided on both sides of the open end of the lower extrusion block 4, wherein one end of the plug-in plate 6 is installed on the connecting ear 5, and the other end is plugged in and installed in the plug-in port 7.

[0047] In this embodiment, the sealing member is preferably a sealing gasket 3 .

[0048] Before plugging the leak, the handle 15 is rotated in the opposite direction, and the handle 15 drives the connected connecting rod 16 to rotate in the opposite direction, and the connecting rod 16 drives the driving gear 17 connected to the outside to rotate in the opposite direction, and the driving gear 17 drives the driven gear 14 meshing with it to rotate in the opposite direction, and the driven gear 14 drives the connected double-headed screw 8 to rotate in the opposite direction. During the reverse rotation of the double-headed screw 8, the two positioning blocks 13 move on the double-headed screw 8 in a direction approaching each other until the two plug-in plates 6 can be disengaged from the two plug-in ports 7, and the reverse rotation of the handle 15 is stopped.

[0049] When plugging the leak, place the lower extrusion block 4 below the ruptured part of the pressure pipe, then adjust the position of the upper extrusion block 2, place the upper extrusion block 2 just above the ruptured part of the pressure pipe, so that the two plug-in plates 6 are plugged into the two plug-in ports 7, then rotate the handle 15 forward until the two positioning blocks 13 pass through the connecting port 12 and the positioning port 11 in turn, and finally abut against the positioning port 10, finally stop the forward rotation of the handle 15, at this time, the sealing gaskets 3 in the upper extrusion block 2 and the lower extrusion block 4 are squeezed by the lower extrusion block 4 and the upper extrusion block 2 to fit the ruptured part of the pressure pipe, which plays a good role in plugging the leak.

[0050] Embodiment 2:

[0051] The difference from the first embodiment is that in this embodiment, the extrusion assembly further includes a rubber limit strip 18 and a limit groove 19. The rubber limit strip 18 is a water drop-shaped structure and is arranged on the outer wall of the seal. The limit groove 19 is a spherical structure and is respectively arranged on the inner side of the upper extrusion block 2 and the lower extrusion block 4. The seal is connected to the limit groove 19 through the rubber limit strip 18. Figure 5As shown, there are multiple rubber limit strips 18, and the multiple rubber limit strips 18 are arranged on the outer wall of the sealing gasket 3 at equal intervals. The limit grooves 19 are also arranged on the inner side of the upper extrusion block 2 and the lower extrusion block 4 at equal intervals, and correspond to the multiple rubber limit strips 18 one by one. The sealing gaskets 3 in the upper extrusion block 2 and the lower extrusion block 4 are very likely to age due to long-term use, resulting in a decrease in the plugging performance. When replacing the sealing gasket 3, pull the sealing gasket 3 away from the upper extrusion block 2 or the lower extrusion block 4 until the multiple rubber limit strips 18 on the sealing gasket 3 are separated from the limit grooves 19 on the upper extrusion block 2 or the lower extrusion block 4, then remove the old sealing gasket 3, and insert the multiple rubber limit strips 18 on the new sealing gasket 3 into the corresponding limit grooves 19 on the inner side of the upper extrusion block 2 or the lower extrusion block 4 by pressing, thereby completing the independent replacement of the aged sealing gasket 3 and eliminating the problem of waste of resources.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
