Description

Technical Field

[0001] This utility model relates to the field of pipeline leakage sealing technology, specifically a rapid sealing device for pipeline leaks at shale gas development sites. Background Technology

[0002] During shale gas extraction, pipelines may experience sudden leaks due to corrosion, external impacts, thread failure, or pressure fluctuations. Leaked natural gas not only wastes resources and causes economic losses but also poses significant risks of combustion, explosion, and environmental pollution. Therefore, rapid and effective containment is essential in the event of a leak.

[0003] However, most existing rapid leak sealing devices for pipelines at shale gas development sites are inconvenient to adjust the spacing to accommodate pipelines of different sizes, making the devices less adaptable and practical. Therefore, a rapid leak sealing device for pipelines at shale gas development sites is proposed to address these issues. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems that most existing rapid sealing devices for pipeline leaks at shale gas development sites are inconvenient to adjust the spacing to accommodate pipelines of different sizes, and that make the devices less adaptable and practical, this utility model proposes a rapid sealing device for pipeline leaks at shale gas development sites.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rapid sealing device for pipeline leakage at shale gas development site, comprising a connecting plate, wherein a through-type sliding groove is provided on the right side inside the connecting plate. The groove has concave blocks at the top and bottom via adjustment components. A rotating block is rotatably connected to the concave block via a rotating rod. A clamping plate is fixedly connected to the right side of the rotating block. A fastening component is provided between the two clamping plates. A sealing component is provided inside the upper clamping plate. The sealing assembly includes a mounting groove formed inside the upper plate, the lower surface of the mounting groove extending to the outside of the upper plate, and a sealing pad disposed inside the mounting groove.

[0006] Preferably, the upper surface inside the mounting groove has a through threaded hole, and a threaded rod is threadedly connected inside the threaded hole. A sealing plate is provided at the bottom end of the threaded rod inside the mounting groove. A groove is provided at the top of the sealing plate, and the bottom end of the threaded rod is inserted into the groove and rotatably connected to the groove through a bearing.

[0007] Preferably, the top of the threaded rod extends to the outside of the upper clamping plate and is fixedly connected to a handle plate, and the opposite sides of the two clamping plates, the sealing plate and the sealing pad are all set in an arc shape.

[0008] Preferably, the adjusting component includes an inner groove on the left side inside the connecting plate, a limiting groove between the inner groove and the sliding groove, a bidirectional screw rotatably installed between the upper and lower surfaces inside the inner groove, an internal threaded sleeve threadedly connected above and below the outer surface of the bidirectional screw, a limiting block slidably connected above and below the limiting groove, and the limiting block is fixedly connected to the internal threaded sleeve and the concave block.

[0009] Preferably, the top end of the bidirectional screw extends to the outside of the connecting plate and is fixedly connected to a throttle handle, and the concave block is slidably connected to the slide groove.

[0010] Preferably, the fastening assembly includes two bolts passing through the front and rear of the two clamping plates respectively, the tops of the bolts extending to the outside of the upper clamping plate and threaded with nuts.

[0011] Preferably, anti-slip textures are provided on the front and rear sides of the two opposing sides of the two card plates.

[0012] The advantages of this utility model are: 1. This utility model drives the bidirectional screw to rotate by rotating the handle. Since the upper and lower surfaces of the bidirectional screw are threaded with internal thread sleeves, and the limiting block is fixedly connected to the internal thread sleeve and the concave block, and the limiting block slides inside the limiting groove, the rotation of the bidirectional screw will drive the two internal thread sleeves to move relative to each other or in opposite directions, thereby driving the two concave blocks to slide relative to each other or in opposite directions in the sliding groove, thereby adjusting the distance between the two clamping plates to adapt to pipes of different sizes; 2. After adjusting the two clamping plates to the appropriate positions, the clamping plates are clamped on both sides of the pipeline leak. At this time, the sealing pad will first contact the pipeline, playing a preliminary sealing role. Then, by rotating the plate, the threaded rod will be driven to rotate. Since the threaded rod is threadedly connected to the threaded hole, and the bottom end of the threaded rod is rotatably connected to the groove on the top of the sealing plate through the bearing, the rotation of the threaded rod will drive the sealing plate to move downward, so that the sealing plate is pressed tightly against the pipeline leak, further enhancing the sealing effect.

Detailed Implementation

[0020] 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.

[0021] Example 1 Please see Figure 1-4 As shown, a rapid sealing device for pipeline leaks at shale gas development sites includes a connecting plate 1, wherein a through-type sliding groove 2 is provided on the right side inside the connecting plate 1. The upper and lower sides of the slide 2 are provided with concave blocks 8 through the adjustment components. The concave blocks 8 are rotatably connected to the rotating blocks 3 through the rotating rod. The right side of the rotating blocks 3 is fixedly connected to the card plate 4. A fastening component is provided between the two card plates 4. A sealing component is provided inside the upper card plate 4. The sealing assembly includes an installation groove 10 inside the upper clamping plate 4, with the lower surface of the installation groove 10 extending to the outside of the upper clamping plate 4. A sealing pad 9 is disposed inside the installation groove 10. During operation, when a shale gas pipeline leaks, the operator first moves the connecting plate 1 to the vicinity of the leaking pipeline, ensuring that the direction of the sliding groove 2 is aligned with the pipeline axis. Then, the two clamping plates 4 can be rotated using a rotating rod to position them above and below the pipeline. The direction of the clamping plates 4 can be adjusted so that the position of the sealing pad 9 corresponds to the leak location. Next, the two clamping plates 4 are fixed to the pipeline using a fastening assembly, and then the sealing assembly is used to seal the leak. At the same time, the spacing between the two clamping plates 4 can be adjusted using an adjusting assembly to accommodate pipelines of different sizes. This allows the device to adapt to pipelines of different sizes within a certain range, thus making the device highly adaptable and practical.

[0022] The upper surface of the mounting groove 10 has a through-hole threaded hole, and a threaded rod 16 is threadedly connected inside the threaded hole. A sealing plate 15 is set inside the mounting groove 10 at the bottom end of the threaded rod 16. A groove 17 is formed at the top of the sealing plate 15. The bottom end of the threaded rod 16 is inserted into the groove 17 and is rotatably connected to the groove 17 through a bearing. During operation, after adjusting the two clamping plates 4 to the appropriate position, the clamping plates 4 are clamped on both sides of the pipeline leak. At this time, the sealing pad 9 will first contact the pipeline, playing a preliminary sealing role. Then the threaded rod 16 rotates. Since the threaded rod 16 is threadedly connected to the threaded hole, and the bottom end of the threaded rod 16 is rotatably connected to the groove 17 at the top of the sealing plate 15 through a bearing, the rotation of the threaded rod 16 will drive the sealing plate 15 to move downward, so that the sealing plate 15 is pressed tightly against the pipeline leak, further enhancing the sealing effect.

[0023] The top of the threaded rod 16 extends to the outside of the upper clamping plate 4 and is fixedly connected to a handle. The opposite sides of the two clamping plates 4, the sealing plate 15, and the sealing pad 9 are all set in an arc shape. During operation, the handle facilitates the rotation of the threaded rod 16, and the arc-shaped clamping plate 4, the sealing pad 9, and the sealing plate 15 facilitate a tight fit with the pipeline.

[0024] The adjusting assembly includes an inner groove 13 located on the left side inside the connecting plate 1. A limiting groove 12 is formed between the inner groove 13 and the sliding groove 2. A bidirectional screw 7 is rotatably installed between the upper and lower surfaces inside the inner groove 13. Internally threaded sleeves 14 are threadedly connected to the upper and lower surfaces of the outer surface of the bidirectional screw 7. Limiting blocks 11 are slidably connected to the upper and lower surfaces inside the limiting groove 12. The limiting blocks 11 are fixedly connected to the internally threaded sleeves 14 and the concave block 8. During operation, when it is necessary to adjust the leak at the shale gas development site pipeline... During the sealing process, the bidirectional screw 7 is first rotated according to the pipe size. Since the upper and lower surfaces of the bidirectional screw 7 are threaded with internal thread sleeves 14, and the limiting block 11 is fixedly connected to the internal thread sleeves 14 and the concave block 8, and the limiting block 11 slides inside the limiting groove 12, the rotation of the bidirectional screw 7 will drive the two internal thread sleeves 14 to move relative to or away from each other, thereby driving the two concave blocks 8 to slide relative to or away from each other in the sliding groove 2, thereby adjusting the distance between the two clamping plates 4 to adapt to pipes of different sizes.

[0025] The top end of the bidirectional screw 7 extends to the outside of the connecting plate 1 and is fixedly connected to a throttle. The concave block 8 is slidably connected to the slide groove 2. During operation, the throttle facilitates the rotation of the bidirectional screw 7, and the concave block 8 can slide inside the slide groove 2.

[0026] The fastening assembly includes two bolts 6 that pass through the front and rear of the two clamping plates 4 respectively. The top of the bolts 6 extends to the outside of the upper clamping plate 4 and is threaded with a nut 5. During operation, the two bolts 6 are passed through the front and rear of the two clamping plates 4 respectively, and the nut 5 is threaded on the top of the bolts 6. By tightening the nut 5, the two clamping plates 4 are firmly fixed together to prevent the clamping plates 4 from loosening during the sealing process, thus ensuring the stability and reliability of the sealing.

[0027] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, anti-slip textures 18 are provided on the front and rear sides of the opposite side of the two clamping plates 4. During operation, the anti-slip textures 18 provided on the side of the clamping plate 4 that is in contact with the pipe increase the friction between the clamping plate 4 and the pipe, making the clamping plate 4 more stable when installed with the pipe.
