Description

Technical Field

[0001] The present invention relates to the technical field of gas pipeline protection devices, and in particular to a gas pipeline risk monitoring device. Background Art

[0002] Gas pipelines are dedicated pipeline systems for gas transportation, which can realize long-distance transportation of gas from supply centers to residential or industrial users. When gas pipelines are transporting gas, if gas leaks occur, it will not only lead to waste of resources, but also pose a serious safety hazard. Therefore, it is very important to prevent and control risks in gas pipelines.

[0003] In gas pipelines, leakage accidents most often occur at the connection points of the pipelines. The main treatment method at present is to use monitoring devices at the connection points of the gas pipelines for prevention. The main preventive measure at present is to install monitoring devices at these connections. Once a gas leak is detected, the monitoring device will quickly issue an alarm to remind people to take timely measures to deal with it.

[0004] In order to better install and tightly wrap the monitoring device on the pipeline, the monitoring device usually adopts a split structure. When in use, the two halves of the structure are placed outside the pipeline and then fixed with bolts. In this way, the monitoring device can close the joints of the pipeline, reduce the risk of leakage, and ensure that the gas can be fully detected, thereby improving the response speed of the monitoring device.

[0005] However, there is a problem with this method of fixing with bolts: only the position close to the bolts can be subjected to sufficient force to fit tightly, while the farther away from the bolts, the smaller the force, and the structure of the monitoring device cannot ensure a tight fit. Therefore, in order to ensure the sealing effect, the number of bolts needs to be increased. Obviously, this will undoubtedly increase the installation workload exponentially and make the disassembly and assembly of the monitoring device cumbersome.

Detailed implementation manners

[0052] To make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0053] Embodiment: A gas pipeline risk monitoring device, as Figures 1-3 shown, includes: an upper half shell 11 and a lower half shell 12, the upper half shell 11 and the lower half shell 12 are assembled and installed at the connection position of the gas pipeline, and a rubber strip is provided at the contact edge of the upper half shell 11 and the lower half shell 12 to improve the tightness after combination; a sealing plate 13, sealing plates 13 are fixedly installed on the front and rear sides of the upper half shell 11 and the lower half shell 12, the sealing plate 13 closes the space between the upper half shell 11 and the lower half shell 12 and the gas pipeline, the inner ring size of the sealing plate 13 is smaller than the outer diameter size of the gas pipeline, and the sealing plate 13 is made of a soft material and can deform. Therefore, after the upper half shell 11 and the lower half shell 12 are assembled and installed outside the gas pipeline, it will be squeezed and deformed, so as to fully close the space between the upper half shell 11 and the lower half shell 12 and the gas pipeline to prevent gas leakage.

[0054] As Figure 2 、Figure 4 , Figure 5 and 6 As shown in Figure 4 , it further includes: a fixing member. A fixing member is provided between the upper half shell 11 and the lower half shell 12. The fixing member is used to stably fix the upper half shell 11 and the lower half shell 12. As shown in Figure 4 , a total of six groups of fixing members are provided between the upper half shell 11 and the lower half shell 12, with three groups provided on each of the left and right sides. Among them, the fixing member includes: a clamping plate 21, the clamping plate 21 is fixedly installed inside the lower half shell 12, and a hook portion is provided on the clamping plate 21; a mounting shaft 22, the mounting shaft 22 is fixedly installed inside the upper half shell 11; a clamping plate 23, the clamping plate 23 is rotatably installed on the mounting shaft 22, and a hook portion is provided at the lower end of the clamping plate 23. When the clamping plate 23 rotates, the hook portion at its lower end will cooperate with the hook portion on the clamping plate 21, so that the clamping plate 23 and the clamping plate 21 cannot be separated from the up and down direction, thereby realizing the stable fixation of the upper half shell 11 and the lower half shell 12; a return spring A 24, the return spring A 24 is sleeved on the mounting shaft 22, and both ends of the return spring A 24 are respectively fixedly installed on the mounting shaft 22 and the clamping plate 23. The return spring A 24 is used to reset the rotated clamping plate 23; a guide rod A 25, the guide rod A 25 is fixedly installed inside the upper half shell 11; a push block 26, the push block 26 is slidably installed on the guide rod A 25, and the push block 26 contacts the upper end of the clamping plate 23. When the push block 26 moves upward, it will squeeze the clamping plate 23 to rotate, so that its lower end cooperates with the clamping plate 21.

[0055] As Figure 2 , Figure 4 , Figure 5 and 6 As shown in Figure 2 , Figure 4 , Figure 5 and 6 , it further includes: a control member. A control member is provided on the upper half shell 11. The control member is connected to the fixing member to control the use of the fixing member. The fixing member is provided on the left and right sides of the upper half shell 11. The control member includes: a screw rod 31, the screw rod 31 is rotatably installed on the side of the upper half shell 11, and three groups of thread sets are provided on each screw rod 31. Each group of thread sets includes two threads arranged in opposite directions; a moving block 32, the moving block 32 is threadedly installed on the screw rod 31. Three groups of moving block sets are provided on each screw rod 31. Each group of moving block sets consists of two moving blocks 32. Each moving block 32 is respectively matched with each section of the thread. When the screw rod 31 rotates, the two moving blocks 32 in each group of moving block sets will move synchronously and in opposite directions; a connecting plate 33, a connecting plate 33 is rotatably installed between the push block 26 and the moving block 32. Each push block 26 will be respectively connected to a connecting plate 33 with two moving blocks 32 in the same group. When the moving block 32 moves, it will control the up and down movement of the push block 26 through the connecting plate 33; a worm 34, the worm 34 is rotatably installed on the left and right sides at the rear of the upper half shell 11; a worm gear 35, the rear ends of the two screw rods 31 are respectively fixedly installed with a worm gear 35, and the two worms 34 are correspondingly meshed with the two worm gears 35.

[0056] ​​Wrap the upper half shell 11 and the lower half shell 12 outside the connection position of the gas pipeline. Rotate the worm 34, and the worm 34 drives the worm gear 35 and the screw 31 to rotate, controlling the two moving blocks 32 of each moving block group to approach each other. Thus, the push block 26 is controlled to move upward along the guide rod A25 through the connecting plate 33. The upward movement of the push block 26 controls the rotation of the buckle plate 23 by pushing the upper end of the buckle plate 23, so that the lower end of the buckle plate 23 abuts against the clamping plate 21, and the two are buckled to fix the upper half shell 11 and the lower half shell 12. First, the action range when the buckle plate 23 cooperates with the clamping plate 21 is wide, ensuring the sealing effect between the upper half shell 11 and the lower half shell 12. Second, the control member can synchronously control all the fixing members on the same side, greatly reducing the installation steps. Therefore, the device has the advantages of good sealing effect and convenient installation. On the contrary, when it is necessary to disassemble the device, reverse the worm 34, control the push block 26 to move downward, and the return spring A24 reverses the buckle plate 23 to release the cooperation between the buckle plate 23 and the clamping plate 21, so as to unlock the fixing of the upper half shell 11 and the lower half shell 12 and achieve quick disassembly.

[0057] As Figure 2 、 Figure 7 and 8 shown, it further includes: a control room 41, which is fixedly installed at the top of the upper half shell 11; a through pipe 42, which is fixedly installed between the control room 41 and the upper half shell 11, and the through pipe 42 makes the space between the two communicate; a top rod 43, which is slidably installed in the control room 41; a return spring B44, which is fixedly installed between the top rod 43 and the control room 41; an alarm 45, which is installed at the top of the upper half shell 11, and the front end of the top rod 43 passes through the control room 41 and the alarm 45 and is arranged in the alarm 45; a button 46, which is fixedly installed at the inner bottom of the alarm 45, and the button 46 is used to control the operation of the alarm 45; a top block 47, which is slidably installed at the inner bottom of the alarm 45, the top block 47 is arranged above the button 46, and the movement of the top rod 43 will contact the top block 47, thereby squeezing the top block 47 to press the button 46; a return spring C48, which is fixedly installed between the top block 47 and the alarm 45.

[0058] When the gas pipeline leaks, the pressure in the space of the upper half shell 11 and the lower half shell 12 increases, and the air pressure will push the top rod 43 to move forward. The top rod 43 squeezes the top block 47 to move downward, thereby pressing the button 46 to start the alarm 45 for warning. Compared with the method of using a detector to detect gas and then controlling the alarm 45 to give a warning through a signal, the warning method of this device is more straightforward and is not easily affected by external factors such as signal interference.

[0059] As Figure 2 、 Figure 9 、 Figure 10 and 11As shown in the figure, it further includes: an installation frame 51, the front and rear parts of the upper half shell 11 are fixedly installed with the installation frame 51, and the installation frame 51 is arranged inside the sealing plate 13; a fixed frame 52, the front and rear parts of the lower half shell 12 are fixedly installed with the fixed frame 52, and the fixed frame 52 is arranged inside the sealing plate 13. When the upper half shell 11 and the lower half shell 12 are fixed together, the installation frame 51 is docked with the fixed frame 52; a guide rod B53, the installation frame 51 is fixedly installed with the guide rod B53; a baffle 54, the installation frame 51 is slidably installed with the baffle 54, the baffle 54 is slidably installed with the guide rod B53, when the baffle 54 moves, it will extend into the fixed frame 52, and at this time the baffle 54 blocks the docking position of the sealing plate 13; a return spring D55, the guide rod B53 is sleeved with the return spring D55, and the two ends of the return spring D55 are respectively fixedly installed on the guide rod B53 and the upper baffle 54.

[0060] As Figure 9 and Figure 10 shown in the figure, it further includes: a wire wheel 61, the front and rear ends of the two screw rods 31 are fixedly installed with the wire wheel 61; a wire rope 62, a wire rope 62 is fixedly installed between the wire wheel 61 and the baffle 54, and the wire rope 62 is wound around the wire wheel 61.

[0061] Since the sealing plate 13 will deform when closing the pipeline, the sealing plate 13 on the upper half shell 11 will be squeezed with the sealing plate 13 on the lower half shell 12, but the contact surface between the sealing plates 13 will generate a gap due to deformation. Therefore, while using the control member to control the fixing member to fix the upper half shell 11 and the lower half shell 12, when the screw rod 31 rotates, the wire wheel 61 is rotated, and the wire rope 62 is wound on the wire wheel 61. Through the wire rope 62, the baffle 54 will be moved to the gap formed between the sealing plates 13, so as to supplement the blockage, further improving the sealing effect of the device; conversely, when disassembling the device, the screw rod 31 rotates in reverse to release the wire rope 62 from the wire wheel 61, and the return spring D55 controls the baffle 54 to reset.

[0062] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected.
