Description

Technical Field

[0001] This utility model relates to the field of pipeline leakage monitoring technology, and in particular to a high-temperature pipeline leakage protection and monitoring device. Background Technology

[0002] In modern industrial production, high-temperature pipelines are widely used in many fields such as petrochemicals, power, and metallurgy, serving as critical infrastructure for transporting high-temperature media. Leaks in high-temperature pipelines not only lead to production interruptions and energy waste but also trigger serious safety accidents, posing a significant threat to human life and property. Therefore, high-temperature pipeline leak protection and monitoring devices are crucial. They can monitor pipeline status in real time, promptly detect potential leaks, and provide early warnings, playing an indispensable role in ensuring the safe and stable operation of industrial production. With the continuous development of industrial technology, higher demands are being placed on the performance and convenience of high-temperature pipeline leak protection and monitoring devices.

[0003] Existing high-temperature pipeline leakage prevention and monitoring devices mostly employ relatively fixed installation methods. Typically, the monitoring device is tightly connected to the pipeline through welding, bolting, or other methods, enabling the device to reliably acquire parameters such as pressure, temperature, and flow rate. Technically, they primarily rely on various sensors to sense the pipeline's operating status. For example, pressure sensors convert pipeline pressure into an electrical signal based on the piezoelectric effect, while temperature sensors utilize the characteristics of thermistors or thermocouples to measure temperature. These signals are then transmitted to a control center for analysis and processing to determine if there is a risk of pipeline leakage.

[0004] However, existing technologies of this kind have a significant problem. When the monitoring device needs maintenance or replacement, it is often difficult to disassemble quickly, requiring a considerable amount of time to remove other related components. For example, some monitoring devices are fixed by welding, requiring the weld points to be cut before maintenance, and care must be taken to avoid damaging surrounding equipment during disassembly; for devices secured by bolts, disassembly is extremely difficult if the bolts are rusted or deformed due to high temperatures. This series of complex operations not only consumes manpower and resources but also greatly increases the complexity and difficulty of maintenance, prolongs the downtime of the pipeline system, and affects production efficiency. Therefore, a high-temperature pipeline leakage protection monitoring device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-temperature pipeline leakage protection and monitoring device, which aims to improve the problem that the existing technology cannot be quickly disassembled, requires a lot of time to remove other related components, and increases the complexity and difficulty of maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-temperature pipeline leakage protection and monitoring device includes a connecting cover, a monitor is installed on the top of the connecting cover, a perforated plate is fixedly connected to the side wall of the monitor, and a quick-release assembly is provided on the inner wall of the perforated plate;

[0008] The quick-release assembly includes a hollow column, the bottom of which is located on top of a hollow plate. A movable column is slidably connected inside the hollow column. A turntable is fixedly connected to one end of the movable column. A retaining ball is slidably connected to the inner wall of the hollow column. A trapezoidal column is fixedly connected to one end of the movable column. A spring is slidably connected to the outer wall of the trapezoidal column. A spring is installed inside the hollow column. One end of the spring is fixedly connected to the inner wall of the hollow column, and the other end of the spring is fixedly connected to the outer wall of the movable column. A drive assembly is installed on the inner wall of the connecting cover.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes a hydraulic cylinder, the sidewall of which is fixedly connected to the inner wall of the connecting cover, and the output end of the hydraulic cylinder is fixedly connected to a second rotating plate.

[0011] As a further description of the above technical solution:

[0012] The first rotating plate is fixedly connected to one side of the second rotating plate, and a clamping plate is fixedly connected to the side wall of the first rotating plate.

[0013] As a further description of the above technical solution:

[0014] A linkage rod is fixedly connected to the side wall of the second rotating plate, and a first connecting plate is fixedly connected to the other end of the linkage rod.

[0015] As a further description of the above technical solution:

[0016] A first gear is fixedly connected to the side wall of the first connecting plate, and a second gear is rotatably connected to the inner wall of the connecting cover.

[0017] As a further description of the above technical solution:

[0018] The first gear meshes with the second gear, and a third connecting plate is fixedly connected to the side wall of the second gear.

[0019] As a further description of the above technical solution:

[0020] The third connecting plate is fixedly connected to one side of the second connecting plate, and another first rotating plate is fixedly connected to the other end of the second connecting plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, pulling the turntable causes the moving column to slide along the trapezoidal column. Subsequently, the movement of the trapezoidal column moves the locking ball on the outer wall, achieving the effect of quick disassembly of the monitor. This solves the problem of not being able to disassemble quickly, requiring a lot of time to remove other related components, which increases the complexity and difficulty of maintenance, and improves the convenience of the pipeline leakage protection and monitoring device.

[0023] 2. In this utility model, the second rotating plate is driven to rotate by a hydraulic cylinder. The second rotating plate, under force, drives the first rotating plate on the side wall to rotate. The first rotating plate, under force, drives the clamping plate on the side wall to rotate. Then, the linkage rod, under force, drives the first connecting plate and the first gear to rotate. The rotation of the first gear drives the second gear meshing with it to rotate, thus achieving the effect of clamping the pipeline. This solves the problem that the monitoring device will move during pipeline operation due to the inability to stably clamp the pipeline, resulting in a change in its relative position with the pipeline. This improves the stability of the pipeline leakage protection monitoring device. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a high-temperature pipeline leakage protection and monitoring device, including a connecting cover 2. The connecting cover 2 is usually made of high-temperature and corrosion-resistant stainless steel to ensure its long-term stability and corrosion resistance in high-temperature and harsh environments. A monitor 1 is provided on the top of the connecting cover 2. A perforated plate 18 is fixedly connected to the side wall of the monitor 1. The perforated plate 18 is generally made of lightweight and high-strength aluminum alloy, which reduces the overall weight and ensures the stability of the structure. A quick-release assembly is provided on the inner wall of the perforated plate 18.

[0032] The quick-release assembly includes a hollow column 13, which is made of high-strength alloy steel to ensure its durability during frequent disassembly and installation. The bottom of the hollow column 13 is set on the top of the hollow plate 18. A movable column 15 is slidably connected inside the hollow column 13. The movable column 15 is usually made of steel with a hardened surface to enhance its wear resistance and service life. A turntable 4 is fixedly connected to one end of the movable column 15. A retaining ball 17 is slidably connected to the inner wall of the hollow column 13. The retaining ball 17 is usually made of high-hardness bearing steel to ensure its stability and wear resistance during high-frequency sliding. A trapezoidal column 16 is fixedly connected to one end of the movable column 15. The outer wall of the trapezoidal column 16 is slidably connected to the inside of a spring 14. A spring 14 is set inside the hollow column 13. The spring 14 is made of high-temperature alloy steel to maintain its elasticity in high-temperature environments. One end of the spring 14 is fixedly connected to the inner wall of the hollow column 13, and the other end of the spring 14 is fixedly connected to the outer wall of the movable column 15. A drive assembly is set on the inner wall of the connecting cover 2.

[0033] Specifically, when maintaining monitor 1, the turntable 4 needs to be pulled first. The turntable 4, under pressure, will cause the movable column 15 on one side to slide, and simultaneously, the movable column 15 will cause the spring 14 on the outer wall to contract. As the movable column 15 slides, the trapezoidal column 16 at one end will also be moved. When the trapezoidal column 16 moves, it will push the retaining ball 17 on the outer wall, causing it to shift. The movement of the retaining ball 17 allows it to slide into the inner wall of the hollow column 13, thus detaching it from the interior of the connecting cover 2, achieving rapid disassembly of monitor 1, facilitating subsequent maintenance and repair. This design not only improves maintenance efficiency but also ensures the stability and safety of the device during disassembly, providing a guarantee for the long-term stable operation of the high-temperature pipeline leakage protection monitoring device.

[0034] Reference Figure 1 and Figure 2 The drive assembly includes a hydraulic cylinder 6, whose sidewall is fixedly connected to the inner wall of the connecting cover 2. A second rotating plate 7 is fixedly connected to the output end of the hydraulic cylinder 6. The second rotating plate 7 is made of high-strength aluminum alloy or carbon steel, ensuring both lightweight design and sufficient strength and rigidity. A first rotating plate 5 is fixedly connected to one side of the second rotating plate 7. The first rotating plate 5 is typically made of surface-hardened alloy steel to improve its wear resistance and service life. A clamping plate 3 is fixedly connected to the sidewall of the first rotating plate 5. A linkage rod 8 is fixedly connected to the sidewall of the second rotating plate 7. The linkage rod 8 is typically made of high-strength alloy steel and heat-treated to improve its fatigue resistance. A first connecting plate 9 is fixedly connected to the other end of the linkage rod 8. A first gear 10 is fixedly connected to the side wall of the 9th gear. Both the first gear 10 and the second gear 11 are made of high-hardness alloy steel and have undergone carburizing and quenching treatment to improve their wear resistance and transmission efficiency. The second gear 11 is rotatably connected to the inner wall of the connecting cover 2. The first gear 10 and the second gear 11 mesh with each other. A third connecting plate 19 is fixedly connected to the side wall of the second gear 11. The third connecting plate 19 is made of high-strength alloy steel to ensure its stability and load-bearing capacity during transmission. A second connecting plate 12 is fixedly connected to one side of the third connecting plate 19. The second connecting plate 12 is usually made of lightweight aluminum alloy or carbon steel, which reduces weight and ensures strength. Another first rotating plate 5 is fixedly connected to the other end of the second connecting plate 12.

[0035] Specifically, when using the high-temperature pipeline leakage protection and monitoring device, the output end of the hydraulic cylinder 6 first drives the second rotating plate 7 to rotate. After the second rotating plate 7 rotates, it will also drive the first rotating plate 5 on one side to rotate. Next, during the rotation of the second rotating plate 7, it will drive the linkage rod 8 on the side wall to rotate. After the linkage rod 8 rotates, it will drive the first connecting plate 9 on the other side to rotate. After the first connecting plate 9 rotates, it will further drive the first gear 10 on its side wall to rotate. At the same time, when the first gear 10 rotates, it will drive the second gear 11 meshing with it to rotate. Next, after the second gear 11 is subjected to force, it will drive the third connecting plate 19 on the side wall to rotate. After the third connecting plate 19 rotates, it will drive the second connecting plate 12 on one side to rotate. Subsequently, after the second connecting plate 12 is subjected to force, it will drive the second rotating plate 7 on the other side to rotate. At the same time, after the second rotating plate 7 is subjected to force, it will drive the first rotating plate 5 and the clamping plate 3 to rotate, achieving the effect of stabilizing the pipeline and ensuring the safety and stability of the high-temperature pipeline during operation.

[0036] Working principle: When using the high-temperature pipeline leakage protection and monitoring device, the output end of the hydraulic cylinder 6 first drives the second rotating plate 7 to rotate. After the second rotating plate 7 rotates, it drives the first rotating plate 5 on one side to rotate as well. Then, after the second rotating plate 7 rotates, it drives the linkage rod 8 on the side wall to rotate. After the linkage rod 8 rotates, it drives the first connecting plate 9 on the other side to rotate. After the first connecting plate 9 rotates, it drives the first gear 10 on the side wall to rotate. At the same time, when the first gear 10 rotates, it drives the second gear 11 that meshes with it to rotate as well. Next, the second gear 11 is forced to drive the third connecting plate 19 on the side wall to rotate. The rotation of the third connecting plate 19 will drive the second connecting plate 12 on one side to rotate. Subsequently, the second connecting plate 12 is forced to drive the second rotating plate 7 on the other side to rotate. At the same time, the second rotating plate 7 is forced to drive the first rotating plate 5 and the clamping plate 3 to rotate, thus achieving the effect of stabilizing the pipeline.

[0037] Next, when maintaining the monitor 1, first pull the turntable 4. The turntable 4, under force, causes the moving column 15 on one side to slide. At the same time, the moving column 15, under force, causes the spring 14 on the outer wall to contract. Then, the moving column 15, under force, causes the trapezoidal column 16 at one end to move as well. When the trapezoidal column 16 moves, it moves the retaining ball 17 on the outer wall, so that the retaining ball 17 can slide to the inner wall of the hollow column 13, so that it can be separated from the inside of the connecting cover 2, achieving the effect of quickly disassembling the monitor 1.

[0038] 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.
