Description

Technical Field

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

[0002] During construction, urban water pipes and drainage pipes are often damaged by excavators. Because the pipes contain rapidly flowing liquid with high internal pressure, liquid can gush out. As a result, maintenance workers are needed to repair the holes or breaks in the pipes. When repairing broken or disconnected pipes, water supply is often cut off, leaving some residents without water during the repair period and disrupting their daily lives. Utility Model Content

[0008] Preferably, the knob has multiple slots evenly distributed on its side, the second limiting seat has a first limiting rod, the first limiting rod is slidably connected to an adjusting block, the adjusting block has a locking block adapted to the slot on its side, and a first spring is provided between the adjusting block and the second limiting seat.

[0009] Preferably, the driving mechanism includes a positioning plate disposed on one side of the closed plate, two second limiting rods symmetrically disposed on the positioning plate, a connecting plate disposed between the two second limiting rods, the second limiting rods passing through the positioning frame, the second limiting rods and the positioning frame being slidably connected, a threaded rod being threadedly connected to the positioning frame, a turntable being disposed at the top of the threaded rod, and a buffer assembly being disposed between the threaded rod and the positioning plate.

At this point, the sealing plate can be pressed against the pipe by rotating the turntable to seal the burst point. This application can complete the emergency repair of the water pipe without interrupting the water supply, which is not only highly efficient but also does not affect the domestic water supply of surrounding residents.

[0014] 2. This application incorporates a second spring in the push plate and the closing plate. The second spring acts as a buffer between the push plate and the closing plate, which can prevent workers from causing secondary damage to the leak due to excessive force during maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A pipe sealing device for emergency pipe repair includes a positioning frame 1. Two arc-shaped clamping plates 2 are symmetrically arranged on both sides of the positioning frame 1. Multiple arc-shaped holes 3 are distributed on the arc-shaped clamping plates 2. A first limiting plate 4 is provided on one side of the arc-shaped clamping plate 2. A first transmission rod 9 is provided at one end of the first limiting plate 4 and is rotatably connected to the positioning frame 1. A transmission mechanism controlling the rotation of the first transmission rod 9 is provided on the positioning frame 1. A sealing plate 24 is provided inside the positioning frame 1. A driving mechanism driving the sealing plate 24 is provided on the positioning frame 1. A second limiting plate 5 is provided at the other end of the arc-shaped clamping plate 2. Positioning holes 8 are provided on the second limiting plate 5. Bolts 6 pass through the positioning holes 8, and nuts 7 are threaded onto the bolts 6. The sealing plate 24 is arc-shaped and used to seal the rupture. The bolts 6 and nuts 7 work together to improve the strength of the sealing device.

[0025] Specifically, such as Figure 3 and Figure 4 As shown, the transmission mechanism includes a worm gear 10 disposed at the end of the first transmission rod 9, a first limiting seat 11 disposed on the side of the positioning frame 1, a second transmission rod 12 rotatably connected to the first limiting seat 11, worms 13 symmetrically disposed at both ends of the second transmission rod 12, the worms 13 and the worm gear 10 meshing with each other, a transmission assembly for driving the second transmission rod 12 to rotate disposed on the side of the positioning frame 1, the transmission assembly including a second limiting seat 14 disposed on the side of the positioning frame 1, a third transmission rod 15 rotatably connected to the second limiting seat 14, a driving bevel gear 16 disposed at the bottom of the third transmission rod 15, a driven bevel gear 17 disposed at one end of the second transmission rod 12, the driving bevel gear 16 and the driven bevel gear 17 meshing with each other, and a knob 18 disposed at the other end of the second transmission rod 12.

[0026] Specifically, such as Figure 4 As shown, multiple slots 19 are evenly distributed on the side of the knob 18. A first limiting rod 22 is provided on the second limiting seat 14. An adjusting block 20 is slidably connected to the upper part of the first limiting rod 22. A locking block 21 that matches the slot 19 is provided on the side of the adjusting block 20. A first spring 23 is provided between the adjusting block 20 and the second limiting seat 14. The first spring 23 can restrict the locking block 21 within the slot 19 to prevent the knob 18 from deflecting.

[0027] Specifically, such as Figure 5 As shown, the driving mechanism includes a positioning plate 25 disposed on one side of the closed plate 24. Two second limiting rods 32 are symmetrically arranged on the positioning plate 25. A connecting plate 30 is disposed between the two second limiting rods 32. The second limiting rods 32 pass through the positioning frame 1 and are slidably connected to the positioning frame 1. A threaded rod 29 is threadedly connected to the positioning frame 1. A turntable 31 is disposed at the top of the threaded rod 29. A buffer assembly is disposed between the threaded rod 29 and the positioning plate 25. The buffer assembly includes a limiting hole 26 opened on the positioning plate 25. A push plate 28 adapted to the limiting hole 26 is disposed at the bottom of the threaded rod 29. A second spring 27 is disposed between the push plate 28 and the limiting hole 26. The second spring 27 can play a buffering role between the push plate 28 and the arc-shaped clamping plate 2, preventing excessive force from the operator during operation and aggravating the pipe rupture.

[0028] In summary, the pipeline sealing device for emergency pipeline repair provided in this embodiment involves engaging two arc-shaped clamps 2 with the pipeline to be sealed, aligning the sealing plate 24 with the rupture location, and then rotating the knob 18. The knob 18 drives the drive bevel gear 16 to rotate via the third transmission rod 15. The drive bevel gear 16 drives the second transmission rod 12 to rotate via the driven bevel gear 17. The second transmission rod 12 drives the worm gear 13 to rotate, the worm gear 13 drives the worm wheel 10 to rotate, and the worm wheel 10 drives the first transmission rod 9 to rotate. Consequently, the first transmission rod 9 drives the two arc-shaped clamps 2 to clamp the pipeline. At this time, the bolt 6 passes through the two positioning holes 8, and the connection between the two arc-shaped clamps 2 is completed with the nut 7. Then, rotating the turntable 31 causes the threaded rod 29 to drive the push plate 28 to slide into the limiting hole 26, compressing the second spring 27. Under the pressure of the second spring 27, the sealing plate 24 is pressed tightly against the rupture of the pipeline, sealing the rupture.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
