Description

Technical Field

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

[0002] Water pipelines are crucial infrastructure in modern water resource management, agricultural irrigation, urban water supply and drainage, and industrial water use. With the development of new materials, intelligent technologies, and green environmental protection technologies, water pipelines are evolving towards higher efficiency, safety, intelligence, and sustainability.

[0003] In existing technologies, conventional pipe sealing devices typically utilize pipe sealing airbags. These airbags, made of high-quality rubber, are inflated by air and use the friction between the airbag wall and the pipe to seal leaks. However, the airbags are supported by excessively long support rods, making it difficult to clamp them after use. This results in the airbags taking up too much space and being difficult to fix later, leading to poor fixation.

[0004] In response to this technical problem, this application proposes a water conservancy pipeline plugging device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water pipe plugging device. By rotating the rotating frame, the first fixing plate is expanded outward until the second rubber pad at the top of the first fixing plate is tightly fitted with the inner wall of the water pipe, thus fixing the plugging device from the inside. This facilitates the support of the airbag. Furthermore, this design avoids the problem of the airbag occupying too much space due to the support rod being too long.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A water pipe plugging device includes a water pipe, a plugging plate at the front end of the water pipe, a connecting rod fixedly connected to the inner wall of the plugging plate, a connecting seat fixedly connected to the rear end of the connecting rod, an airbag fixedly fixed to the inner wall of the rear end of the connecting seat, an air inlet assembly at the front end of the airbag, support frames fixedly connected to the four corners of the outer wall of the connecting seat, a first fixing assembly at the front end of the support frame, an adjustment assembly on the outer wall of the connecting seat, and a connecting frame fixedly connected to the four corners of the front end of the plugging plate by bolts. A second fixing assembly is provided on the inner wall of the connecting frame.

[0007] Furthermore, the air intake assembly includes an air intake pipe fixedly connected to the front end of the airbag, the outer wall of the air intake pipe being fixedly connected to the inner wall of the connecting rod, and an air nozzle being fixedly connected to the front end of the air intake pipe.

[0008] Furthermore, the first fixing component includes a rotating frame rotatably connected to the front end of the support frame, and a first fixing plate is rotatably connected to one end of the outer side of the rotating frame.

[0009] Furthermore, a second rubber pad is provided at the top of the first fixing plate, and the outer wall of the second rubber pad is in contact with the inner wall of the water pipe.

[0010] Furthermore, the adjustment assembly includes a sliding ring slidably connected to the outer wall of the connecting seat, a connecting plate fixedly connected to the front end of the sliding ring, a threaded ring rotatably connected to the front end of the connecting plate, and one end of the inner side of the rotating frame rotatably connected to the outer wall of the sliding ring.

[0011] Furthermore, the outer wall of the front end of the connecting rod is provided with threads, and the inner wall of the threaded ring is threadedly connected to the outer wall of the connecting rod.

[0012] Furthermore, a rubber sealing gasket is provided between the water pipe and the sealing plate.

[0013] Furthermore, the second fixing component includes a connecting ring fixedly connected to the inner wall of the connecting frame. A threaded rod is threadedly connected to the inner wall of the connecting ring. A knob is fixedly connected to one outer end of the threaded rod. A second fixing plate is rotatably connected to one inner end of the threaded rod. A first rubber pad is provided on one inner end of the second fixing plate. One inner end of the first rubber pad is in contact with the outer wall of the water pipe.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the first fixing plate is expanded outward by rotating the rotating frame until the second rubber pad at the top of the first fixing plate is tightly attached to the inner wall of the water pipe, thus fixing the blocker from the inside, which facilitates the support of the airbag. Moreover, this design avoids the problem of the airbag occupying too much space due to the support rod being too long.

[0015] 2. In this utility model, the second fixing plate is moved inward by the movement of the threaded rod until the first rubber pad on the inner side of the second fixing plate is tightly attached to the outer wall of the water pipe, thus fixing the plug from the outside. At this time, the sealing plate and the rubber sealing pad play a further sealing role. Through double fixing inside and outside, the fixing effect of the plug on the water pipe is greatly improved.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a water pipe sealing device, including a water pipe 1, a sealing plate 2 at the front end of the water pipe 1, a connecting rod 3 fixedly connected to the inner wall of the sealing plate 2, a connecting seat 4 fixedly connected to the rear end of the connecting rod 3, an airbag 5 fixedly fixed to the inner wall of the rear end of the connecting seat 4, an air inlet pipe 6 fixedly connected to the front end of the airbag 5, an air nozzle 7 fixedly connected to the front end of the air inlet pipe 6, support frames 8 fixedly connected to the four corners of the outer wall of the connecting seat 4, a rotating frame 9 rotatably connected to the front end of the support frame 8, and an air nozzle 7 fixedly connected to the front end of the rotating frame 9. The first fixed plate 10 is rotatably connected to the end of the water pipe 1. The top of the first fixed plate 10 is provided with a second rubber pad 21. The outer wall of the second rubber pad 21 is in contact with the inner wall of the water pipe 1. The outer wall of the connecting seat 4 is slidably connected to the sliding ring 11. The front end of the sliding ring 11 is fixedly connected to the connecting plate 12. The front end of the connecting plate 12 is rotatably connected to the threaded ring 13. One end of the inner side of the rotating frame 9 is rotatably connected to the outer wall of the sliding ring 11. The outer wall of the front end of the connecting rod 3 is provided with threads. The inner wall of the threaded ring 13 is threadedly connected to the outer wall of the connecting rod 3. A rubber sealing gasket is provided between the water pipe 1 and the sealing plate 2. Specifically, when it is necessary to seal a water pipeline, the sealing plate 2 is first placed at an appropriate position at the front end of the water pipe 1. Then, air is injected into the air inlet pipe 6 through the air nozzle 7. The gas enters the air bladder 5 through the air inlet pipe 6, causing the air bladder 5 to inflate. After inflating, the air bladder 5 fits tightly against the inner wall of the water pipe 1, thereby sealing the pipeline.

[0020] Next, rotate the threaded ring 13. Since the inner wall of the threaded ring 13 is threadedly connected to the outer wall of the connecting rod 3, the rotation of the threaded ring 13 will cause the connecting plate 12 and the sliding ring 11 to slide on the outer wall of the connecting seat 4. The sliding of the sliding ring 11 will then cause the rotating frame 9 to rotate, causing the first fixing plate 10 to unfold outwards until the second rubber pad 21 at the top of the first fixing plate 10 is tightly fitted against the inner wall of the water pipe 1, thus fixing the sealer from the inside and facilitating support for the airbag 5. Furthermore, this design avoids the problem of excessively large footprint caused by using an excessively long support rod to support the airbag 5.

[0021] Reference Figure 1 and Figure 2 The four corners of the front end of the sealing plate 2 are fixedly connected to the connecting frame 14 by bolts 15. The inner wall of the connecting frame 14 is fixedly connected to the connecting ring 16. The inner wall of the connecting ring 16 is threadedly connected to the threaded rod 17. The outer end of the threaded rod 17 is fixedly connected to the knob 18. The inner end of the threaded rod 17 is rotatably connected to the second fixing plate 19. The inner end of the second fixing plate 19 is provided with the first rubber pad 20. The inner end of the first rubber pad 20 is in contact with the outer wall of the water pipe 1. Specifically, turning knob 18 again causes the threaded rod 17 to rotate within the connecting ring 16. Since they are threaded together, the threaded rod 17 moves inward, thereby moving the second fixing plate 19 inward. This continues until the first rubber gasket 20 on the inner side of the second fixing plate 19 is tightly fitted against the outer wall of the water pipe 1, thus fixing the plug from the outside. At this point, the plugging plate 2 and the rubber sealing gasket provide further sealing.

[0022] The dual internal and external fixing method greatly improves the sealing effect of the plug on water pipe 1. Furthermore, the device has a compact structure, does not occupy excessive space, and is easy to operate and use.

[0023] Working principle: When it is necessary to block water pipes, first place the blocking plate 2 at a suitable position at the front end of the water pipe 1. Then, inflate the air inlet pipe 6 through the air nozzle 7. The gas enters the air bag 5 through the air inlet pipe 6, causing the air bag 5 to inflate. After the air bag 5 inflates, it fits tightly against the inner wall of the water pipe 1, thus blocking the pipe.

[0024] By rotating the threaded ring 13, since the inner wall of the threaded ring 13 is threadedly connected to the outer wall of the connecting rod 3, the rotation of the threaded ring 13 will cause the connecting plate 12 and the sliding ring 11 to slide on the outer wall of the connecting seat 4. The sliding ring 11 will then cause the rotating frame 9 to rotate. The rotation of the rotating frame 9 will cause the first fixing plate 10 to unfold outward until the second rubber pad 21 at the top of the first fixing plate 10 is tightly attached to the inner wall of the water pipe 1, thus fixing the blocker from the inside. This facilitates the support of the airbag 5. Furthermore, this design avoids the problem of the airbag 5 occupying too much space due to the support of the long support rod.

[0025] At this point, turn knob 18 again. Knob 18 drives threaded rod 17 to rotate on the inner wall of connecting ring 16. Due to the threaded connection, threaded rod 17 will move inward. The movement of threaded rod 17 drives second fixing plate 19 to move inward until the first rubber pad 20 on the inner side of second fixing plate 19 is tightly attached to the outer wall of water pipe 1, fixing the plug from the outside. At this time, the sealing plate 2 and rubber sealing pad play a further sealing role.

[0026] The double fixation, both internal and external, greatly improves the fixing effect of the plug on water pipe 1. It also has a compact structure, does not take up too much space, and is easy to operate and use.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
