Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline maintenance, specifically a gas pipeline rapid leak sealing device. Background Technology

[0002] In gas pipeline networks, after a period of use, gas pipelines inevitably leak due to their own structure and external factors. If the leaks are not plugged in time, they will affect the surrounding environment. Existing gas pipeline leak sealing devices generally use bolts to tighten the clamps at the leak point. However, the bolt-tightening process is slow and cannot achieve a quick sealing effect. Moreover, gas continues to leak while the bolts are being tightened, which has a significant impact on the health of the operators. Therefore, we have designed a device that can quickly seal gas pipeline leaks. Utility Model Content

[0003] This invention provides a device for quickly sealing gas pipeline leaks, which addresses the deficiencies in existing technologies.

[0004] This utility model is achieved through the following technical solution:

[0005] A gas pipeline rapid leak sealing device includes two semicircular plates, each with a coaxial clamping plate. One end of the two semicircular plates is hinged together, and the other end of the semicircular plates is connected by a snap fastener. The clamping plates are slidably mounted on the corresponding semicircular plates. Through slots are opened on the semicircular plates, and several cams are rotatably installed in the through slots. Each cam has an integrated push block.

[0006] As described above, a gas pipeline rapid leak sealing device has several connecting rods fixedly installed on the clamp plate, and several sliding grooves are opened on the semi-circular plate. The connecting rods extend into the corresponding sliding grooves and are fixedly connected to the sliders.

[0007] As described above, a gas pipeline rapid leak sealing device has rubber pads fixedly installed on the clamps.

[0008] As described above, a gas pipeline rapid leak sealing device has a through hole on one of the push blocks on the semi-circular plate, a first pull rope is provided in the through hole, and a stop bar is fixedly installed on the side of the through groove near the buckle. The first pull rope passes through the gap between the stop bar and the inner wall of the through groove.

[0009] As described above, in a gas pipeline rapid leak sealing device, a second pull rope is fixedly connected to one side of the semicircular plate.

[0010] As described above, in a gas pipeline rapid leak sealing device, a rotating wheel is fixedly installed on the hinge shaft at the hinge joint of the two semicircular plates, and the rotating wheel can contact the pipeline.

[0011] As described above, a gas pipeline rapid leak sealing device has sliding holes in the through groove, and a T-shaped rod is slidably installed in the sliding hole. The T-shaped rod has an inclined surface that can slide and cooperate with the push block. The T-shaped rod is connected to the semi-circular plate by a spring.

[0012] The advantages of this invention are: It has a simple structure and ingenious design. By rotating the cam, the clamp can quickly seal the leak point, eliminating the slow process of tightening bolts and effectively shortening the sealing time. It meets practical needs and is suitable for widespread application. When using this invention, release the latch, rotate the two semicircular plates, and then mount the device onto the pipe, bringing the clamp close to the leak point. Then, restrict the rotation of the two semicircular plates with the latch, and push the push block to rotate the cam. Based on the lever principle, the push block drives the cam with less effort. The rotating cam compresses the clamp towards the pipe until it presses the clamp firmly against the pipe, thus sealing the leak. The operation is simple and quick. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] A rapid leak-sealing device for gas pipelines, such as Figure 1 , 2As shown, the device includes two semicircular plates 1, each with a coaxial clamping plate 2. The clamping plate 2 and the semicircular plate 1 are coaxially arranged, with one end of each semicircular plate 1 hinged together and the other end connected by a latch 3. The latch 3 is a mature existing technology and will not be described in detail. The clamping plates 2 are slidably mounted on their respective semicircular plates 1. A through groove 4 is formed on each semicircular plate 1, and several cams 5 are rotatably mounted within each through groove 4. Each cam 5 has a through hole, and a support shaft is installed within each through hole. The two ends of the support shaft are fixedly connected to the inner wall of the through groove 4. An integrated push block 6 is provided on each cam 5. This utility model has a simple structure and ingenious design. By rotating the cams 5, the clamping plate 2 can quickly seal the leak point, eliminating the slow process of tightening bolts and effectively shortening the sealing time. It meets practical needs and is suitable for widespread application. When using this utility model, release the buckle 3, rotate the two semicircular plates 1, put the device on the pipe, and make the clamp 2 close to the leak point. Then, make the buckle 3 restrict the rotation of the two semicircular plates 1, and then push the push block 6 to drive the cam 5 to rotate. According to the lever principle, it is easier to drive the cam 5 by the push block 6. The cam 5 rotates and squeezes the clamp 2 to move closer to the pipe until the cam 5 presses the clamp 2 tightly on the pipe, and the pipe leak point is sealed. The operation is simple and fast.

[0018] Specifically, as shown in the figure, in this embodiment, several connecting rods 20 are fixedly installed on the clamping plate 2, and several sliding grooves 21 are opened on the semicircular plate 1. The connecting rods 20 extend into the corresponding sliding grooves 21 and are fixedly connected to the sliders 22. The connecting rods 20 pass through the reserved holes on the semicircular plate 1, and the reserved holes communicate with the corresponding sliding grooves 21. When the cam 5 pushes the clamping plate 2 to move, the connecting rods 20 drive the corresponding sliders 22 to slide in the sliding grooves 21, thereby restricting the clamping plate 2 to move only along the direction of the sliding grooves 21 and preventing the clamping plate 2 from deviating.

[0019] Specifically, as shown in the figure, rubber pads 30 are fixedly installed on the clamping plate 2 in this embodiment. The rubber pads 30 can increase the sealing effect and also increase the friction to prevent the clamping plate 2 from shifting.

[0020] Furthermore, as shown in the figure, in this embodiment, a through hole is opened on one of the push blocks 6 on the semicircular plate 1, and a first pull rope 40 is provided in the through hole. A stop bar 41 is fixedly installed on the side of the through groove 4 near the buckle 3. The first pull rope 40 passes through the gap between the stop bar 41 and the inner wall of the through groove 4. This device can be first fitted onto the pipeline at a position far from the leak point, and then moved to the leak point from a distance. By pulling the first pull rope 40, and under the guidance of the stop bar 41, the cam 5 is driven to rotate, thereby achieving the rotation of the cam 5 at a position far from the pipeline leak point. This causes one cam 5 in the through groove 4 to rotate first, pushing the clamping plate 2 closer to the pipeline. After this cam 5 is pressed, the pipeline is initially blocked. Then, other cams 5 are rotated closer to the device to complete the pressing, avoiding close-range sealing and reducing the impact of leaked gas on the operator.

[0021] Furthermore, as shown in the figure, a second pull rope 50 is fixedly connected to one side of the semicircular plate 1 in this embodiment. After the device is mounted on the pipeline, it can be easily moved along the pipeline axis by pulling the second pull rope 50 from a distance, thus making it easier to move the device to the leak point.

[0022] Furthermore, as shown in the figure, in this embodiment, a rotating wheel 60 is fixedly installed on the hinge shaft at the hinge joint of the two semicircular plates 1. The rotating wheel 60 can contact the pipe. When the device is pulled by the second pull rope 50, the rotating wheel 60 rotates on the pipe, thereby changing the sliding friction into rolling friction, reducing the resistance to movement, and making it more convenient to use.

[0023] Furthermore, as shown in the figure, in this embodiment, sliding holes are respectively opened in the through groove 4, and T-shaped rods 70 are slidably installed in the sliding holes. The T-shaped rods 70 are provided with inclined surfaces that can slide and engage with the push block 6. The inclined surfaces of the T-shaped rods 70 are located at the front end. The T-shaped rods 70 are connected to the semi-circular plate 1 through springs 71. The springs 71 are fitted onto the T-shaped rods 70, with one end of the springs 71 fixedly connected to the semi-circular plate 1 and the other end of the springs 71 fixedly connected to the T-shaped rods 70. When the push block 6 and the cam 5 rotate to contact the inclined surfaces of the T-shaped rods 70, they apply a pushing force to the T-shaped rods 70, causing them to move along the sliding holes. The springs 71 are compressed. When the push block 6 and the cam 5 pass over the T-shaped rods 70, the T-shaped rods 70 return to their original position under the action of the springs 71, blocking the T-shaped rods 70. The cam 5 cannot return to its original position, thus maintaining the pressure on the clamping plate 2. To release the restriction, the T-shaped rods 70 can be pulled by hand until they no longer block the pressure.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
