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

[0002] In urban gas supply systems, gas pipelines are crucial facilities for transporting gas, and their safe and stable operation is of paramount importance. However, due to their long-term underground burial or exposure to complex environments, pipelines are susceptible to corrosion, external damage, aging, and other factors, often resulting in gas leaks. Once a gas leak occurs, it not only wastes energy but can also trigger serious safety accidents such as fires and explosions, posing a significant threat to people's lives and property and social stability.

[0003] However, some simple sealing methods require the use of suitable sealing plates and welding, which involves electric welding. The operation is relatively cumbersome, requires professional tools and a lot of manpower, and the repair time is long. In order to avoid danger during the repair process, the gas supply may be interrupted for a long time, which will cause great inconvenience to residents' lives and business production and reduce the efficiency of repair. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rapid sealing device for emergency repair of gas pipelines.

[0005] The gas pipeline emergency repair quick sealing device provided by this utility model includes: a pipeline body, an installation plate, an adjustment structure, a sealing plate, and a fixing structure. The installation plate is provided on the lower surface of the pipeline body. A guide groove is provided on the upper surface of the installation plate. An adjustment structure is provided inside the guide groove on the upper surface of the installation plate. The adjustment structure includes a sliding block and a positive and negative threaded rod. Two sliding blocks are provided, and the two sliding blocks are slidably connected to the guide groove on the upper surface of the installation plate. A threaded hole is provided at one end of each sliding block. A positive and negative threaded rod is threaded inside the threaded hole at one end of each sliding block. A sealing plate is attached to the upper surface of the pipeline body. Fixing structures are provided on the outer surfaces of both ends of the sealing plate. The fixing structure includes a fixed half-ring, a movable half-ring, and a screw. A movable half-ring is hinged to one end of the fixed half-ring. A threaded hole is provided on the upper surface of the movable half-ring. A screw is threaded inside the threaded hole on the upper surface of the movable half-ring.

[0006] Preferably, one end of the mounting plate has a through hole, and the inner walls of both sides of the guide groove on the upper surface of the mounting plate have limit grooves.

[0007] Preferably, limiting slides are fixedly connected to both sides of the two sliding blocks respectively, and the limiting slides on both sides of the two sliding blocks are slidably connected to the inner walls of the limiting slide grooves on both sides of the upper surface of the mounting plate. The upper surfaces of the two sliding blocks are fixedly connected to the lower surface of the fixing half ring in the fixing structure of the outer surfaces of both ends of the sealing plate respectively, and the threaded holes at one end of the two sliding blocks are located at the positive and negative threads of the positive and negative threaded rod respectively.

[0008] Preferably, one end of the positive and negative threaded rod is rotatably connected to the inner wall of the guide groove on the upper surface of the mounting plate, and the other end of the positive and negative threaded rod extends through the through hole at one end of the mounting plate to the outer surface of the mounting plate. A first rotating wheel is fixedly connected to the end of the positive and negative threaded rod extending to the outer surface of the mounting plate.

[0009] Preferably, a sliding groove is formed on the upper surface of the sealing plate, and a sliding rod is provided inside the sliding groove on the upper surface of the sealing plate. The two ends of the sliding rod are respectively fixedly connected to the inner walls of the two ends of the sliding groove on the upper surface of the sealing plate.

[0010] Preferably, both the fixed half-ring and the movable half-ring have threaded holes at the ends away from the hinge, and bolts are threaded inside the threaded holes at the ends away from the hinge of the fixed half-ring and the movable half-ring.

[0011] Preferably, a second rotating wheel is fixedly connected to the upper end of the screw, and an extrusion block is rotatably connected to the lower end of the screw. One end of the extrusion block has a through hole, and the through hole at one end of the extrusion block is slidably connected to the outer surface of the sliding rod.

[0012] Compared with related technologies, the gas pipeline emergency repair quick sealing device provided by this utility model has the following beneficial effects:

[0013] 1. With an adjustable structure, rotating the first rotating wheel drives the positive and negative threaded rods to rotate. The positive and negative threads of the positive and negative threaded rods are respectively threadedly connected to the threaded holes at one end of the two sliding blocks. When the positive and negative threaded rods rotate, the two sliding blocks will move simultaneously in opposite or opposite directions within the guide groove of the mounting plate. The movement of the sliding blocks will drive the fixed half-rings in the fixing structure at both ends of the sealing plate to move synchronously, thereby adjusting the position of the sealing plate applying the extrusion pressure on the pipe body, so that the sealing plate is aligned with the leak, which greatly shortens the preparation time for emergency repair and improves the efficiency of emergency repair.

[0014] 2. By setting a fixed structure, rotating the second rotating wheel drives the screw to rotate. The extrusion block connected to the lower end of the screw is slidably connected to the outer surface of the sliding rod in the sliding groove on the upper surface of the sealing plate due to its through hole at one end. The rotation of the screw causes the extrusion block to move downward along the sliding groove on the sliding rod. As the extrusion block moves downward, it applies a downward extrusion force to the sealing plate through the sliding rod, making the sealing plate tightly adhere to the gas leakage point of the pipe body. The sealing effect of the sealing plate prevents the gas from continuing to leak, and the sealing plate tightly adheres to the gas leakage point of the pipe body. The sealing effect is significant, effectively preventing gas leakage and reducing safety risks. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The system includes: a pipe body, a mounting plate, an adjusting structure, a sealing plate, and a fixing structure. The mounting plate is located on the lower surface of the pipe body. A guide groove is formed on the upper surface of the mounting plate. An adjusting structure is located inside the guide groove on the upper surface of the mounting plate. The adjusting structure includes sliding blocks and threaded rods. Two sliding blocks are provided, each slidably connected to the guide groove on the upper surface of the mounting plate. One end of each sliding block has a threaded hole, and the threaded holes at one end of each sliding block are threaded with threaded rods. A sealing plate is attached to the upper surface of the pipe body. The sealing plate is made of rubber, which has good flexibility and elasticity, allowing it to tightly adhere to the pipe surface and prevent damage. Even uneven surfaces can achieve a good seal, and the rubber has good resistance to gas, is not easily corroded by gas, has high chemical stability, and is relatively inexpensive. The adjustment structure is used to adjust the pressure point applied to the sealing plate. The outer surfaces of both ends of the sealing plate are respectively equipped with a fixing structure, which includes a fixed half ring, a movable half ring, and a screw. One end of the fixed half ring is hinged to the movable half ring, and the upper surface of the movable half ring has a threaded hole. The screw is threaded inside the threaded hole on the upper surface of the movable half ring. When it is necessary to attach the sealing plate to the leak in the pipe body, the operator first unfolds the movable half ring, attaches the fixed plate ring to the outer surface of the pipe body, and then closes the movable half ring.

[0021] In the specific implementation process, a through hole is opened at one end of the mounting plate, and limit grooves are opened on both sides of the guide groove on the upper surface of the mounting plate. The mounting plate provides a mounting base for other components. The guide groove on the upper surface of the mounting plate provides a sliding track for the sliding block of the adjustment structure, so that the sliding block can move inside it. The limit grooves on both sides of the guide groove on the upper surface of the mounting plate, together with the limit slides on the sliding block, play a limiting role and prevent the sliding block from leaving the guide groove during the sliding process. The through hole at one end of the upper surface of the mounting plate provides a channel for the positive and negative threaded rods to pass through, so that the positive and negative threaded rods can extend to the outer surface of the mounting plate for operation.

[0022] The two sliding blocks are fixedly connected to limiting slide plates on both sides. The limiting slide plates on both sides of the two sliding blocks are slidably connected to the inner walls of the limiting slide grooves on both sides of the guide slide groove on the upper surface of the mounting plate. The upper surfaces of the two sliding blocks are fixedly connected to the lower surface of the fixed half ring in the fixing structure at both ends of the sealing plate. When the two sets of sliding blocks move, they can drive the fixed half ring to move. The threaded holes at one end of the two sliding blocks are located at the positive and negative threads of the positive and negative threaded rods, respectively. When the positive and negative threaded rods rotate, the positive and negative threads are threadedly connected to the threaded holes at one end of the two sliding blocks, which can enable the two sliding blocks to move in opposite directions or towards each other at the same time, thereby realizing the precise adjustment of the position of the sealing plate compression point to adapt to the emergency sealing needs of different leaks in the pipeline.

[0023] One end of the positive and negative threaded rod is rotatably connected to the inner wall of the guide groove on the upper surface of the mounting plate, and the other end of the positive and negative threaded rod extends through the through hole at one end of the mounting plate to the outer surface of the mounting plate. The positive and negative threaded rod can rotate inside the through hole at one end of the mounting plate. The first rotating wheel is fixedly connected to the end of the positive and negative threaded rod extending to the outer surface of the mounting plate. The first rotating wheel makes it convenient for the operator to hold and rotate the positive and negative threaded rod.

[0024] The sealing plate has a sliding groove on its upper surface, and a sliding rod is installed inside the sliding groove. The two ends of the sliding rod are fixedly connected to the inner walls of the two ends of the sliding groove on the upper surface of the sealing plate. The sliding rod provides a sliding track for the extrusion block, allowing the extrusion block to slide on the sliding rod without hindering the mutual adjustment of the spacing between the fixed structures at both ends of the sealing plate. This allows the extrusion point to be adjusted according to the air leakage point of the pipe body, thus extruding the sealing plate to the optimal sealing position.

[0025] Both the fixed half-ring and the movable half-ring have threaded holes at the ends away from the hinge. Bolts are threaded inside the threaded holes at the ends away from the hinge of the fixed half-ring and the movable half-ring. The bolts connect and fix the fixed half-ring and the movable half-ring together, so that the fixing structure can stably wrap around the pipe body and ensure the fixing effect of the sealing plate.

[0026] The upper end of the screw is fixedly connected to a second rotating wheel, which is convenient for the operator to hold and rotate. The lower end of the screw is rotatably connected to a pressing block, one end of which has a through hole. The through hole of the pressing block is slidably connected to the outer surface of the sliding rod. When the screw rotates, it will press the adjusting block, thereby causing the pressing block to press the sealing plate through the sliding rod, thus compressing the sealing plate and making the sealing plate tightly fit against the leak in the pipe body, enhancing the sealing effect.

[0027] The working principle of this utility model is as follows: When a gas leak is found in the gas pipeline and emergency repair is needed, first, keep the mounting plate horizontal with respect to the leak in the pipeline. The operator holds and rotates the first rotating wheel, which drives the positive and negative threaded rods to rotate. The positive and negative threads of the positive and negative threaded rods are respectively threaded into the threaded holes at one end of the two sliding blocks. According to the characteristics of threaded transmission, when the positive and negative threaded rods rotate, the two sliding blocks will move simultaneously in opposite or opposite directions within the guide groove of the mounting plate. The limiting slides on both sides of the sliding blocks slide within the limiting slide grooves on the inner walls of the guide grooves on both sides of the mounting plate, ensuring that the movement of the sliding blocks remains on the specified path and there will be no deviation or disengagement. Since the upper surfaces of the two sliding blocks are respectively fixedly connected to the lower surfaces of the fixed half-rings in the fixing structures at both ends of the sealing plate, the movement of the sliding blocks will drive the fixed half-rings in the fixing structures at both ends of the sealing plate to move synchronously. The sliding rod provides a sliding track for the extrusion block, allowing the extrusion block to slide on the sliding rod without hindering the mutual adjustment of the spacing between the fixing structures at both ends of the sealing plate, thereby adjusting the sealing plate on the pipeline. After determining the location for applying pressure to the sealing plate, unfold the movable half-ring and place the fixed half-ring against the corresponding position on the outer surface of the pipe body. Then close the movable half-ring so that it and the fixed half-ring together encircle the pipe body. Connect and secure the fixed and movable half-rings together by screwing bolts into the threaded holes at the ends of the fixed and movable half-rings away from the hinge. This initially fixes the position of the sealing plate. At this point, the sealing plate is in contact with the surface of the pipe body, but a tight seal has not yet been achieved. The operator holds and rotates the second rotating wheel, which drives the screw to rotate. The extrusion block connected to the lower end of the screw is slidably connected to the outer surface of the sliding rod in the sliding groove on the upper surface of the sealing plate through a through hole at one end. Therefore, the rotation of the screw causes the extrusion block to move downward along the sliding groove on the sliding rod. As the extrusion block moves downward, it applies a downward pressure to the sealing plate through the sliding rod, making the sealing plate tightly adhere to the leak in the pipe body. The sealing effect of the sealing plate prevents further gas leakage, achieving rapid sealing and emergency repair of the gas pipeline.
