Technical Field

[0001] This utility model belongs to the field of sulfur hexafluoride gas leakage monitoring technology, specifically, it relates to an online sulfur hexafluoride gas leakage alarm device. Background Technology

[0002] Gas monitoring systems are generally divided into control, sensor, and management platform components. They can achieve functions such as remote unattended operation, real-time data transmission, over-limit alarm, equipment linkage, and data analysis, making them an indispensable device in gas transportation.

[0003] Sulfur hexafluoride (SF6) is an essential gas in both military and civilian applications. It is usually transported via pipelines, and gas leak detectors are required to detect any leaks during transport.

[0004] Existing devices are found to use fasteners to install the monitoring device and the pipeline. However, these fasteners are exposed and susceptible to rust due to the external environment, making them difficult to remove. Furthermore, the installation of these fasteners requires specialized tools, which leads to technical issues such as limited lifespan and cumbersome installation.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the technical problems of monitoring device installation, the basic concept of the technical solution adopted by this utility model is as follows: An online sulfur hexafluoride gas leak alarm device includes a main body with a connecting pipe fixedly connected to it, and a monitoring module disposed on the connecting pipe. An assembly component is disposed on the connecting pipe and is used to assemble the monitoring module. The assembly component includes a first connecting plate, a second connecting plate, a first connecting block, a second connecting block, and a limiting rod. The connecting pipe is fixedly connected to the second connecting plate, and the first and second connecting plates are in close contact. The first connecting blocks are symmetrically disposed on the first connecting plates, and the second connecting blocks are symmetrically disposed on the second connecting plates. The limiting rod is disposed on a corresponding first connecting block, and its bottom engages with the second connecting block.

[0007] In a preferred embodiment of this utility model, the corresponding first connecting block is fixedly connected to the first connecting plate, the corresponding second connecting block is fixedly connected to the second connecting plate, and the corresponding limiting rod is movably set with respect to the first connecting block.

[0008] In a preferred embodiment of the present invention, each of the first connecting blocks is symmetrically provided with a support rod, each support rod is fixedly connected to the corresponding first connecting block, and the corresponding first connecting blocks are slidably connected with the same threaded ring.

[0009] In a preferred embodiment of the present invention, each of the support rods is fitted with a spring, and the end of each spring is fixedly connected to the corresponding first connecting block and support rod.

[0010] In a preferred embodiment of this utility model, the corresponding limiting rod and the threaded ring are connected by a thread, and an abutment block is fixedly connected to the bottom of each limiting rod.

[0011] In a preferred embodiment of the present invention, each of the second connecting blocks has a snap-fit ​​groove and a through groove at its bottom, the snap-fit ​​groove and the through groove are staggered, and the corresponding abutting block snaps into the snap-fit ​​groove.

[0012] In a preferred embodiment of the present invention, each of the first connecting blocks is fixedly connected to a mounting block, and each mounting block is rotatably connected to a rotating rod.

[0013] In a preferred embodiment of the present invention, each of the rotating rods is fixedly connected to a support block, and the end of each support block abuts against the corresponding first connecting block and threaded ring.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This online sulfur hexafluoride gas leak alarm device achieves positioning, locking, and fixing functions through the interaction of a limiting rod, threaded ring, spring, and snap-fit ​​groove, with the limiting rod being pressed and rotated. This avoids the cumbersome installation caused by traditional fastener installation methods and the difficulty in removal due to rust, thus improving the installation and removal efficiency of this device.

[0015] 2. This online sulfur hexafluoride gas leak alarm device allows for manual rotation of a rotating rod, which causes the support block to rotate vertically, bringing the end of the support block into contact with the first connecting block and the threaded ring. This restricts the space between the threaded ring and the first connecting block, preventing the limiting rod from pushing downwards and restricting the contact block from moving upwards. This achieves stable locking of the device and prevents loosening between components, which could lead to unstable installation.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] Please see Figure 1-5 A sulfur hexafluoride gas online leak alarm device includes a main body 1, a connecting pipe 11 fixedly connected to the main body 1, a monitoring module 2 disposed on the connecting pipe 11; and an assembly component disposed on the connecting pipe 11 for assembling the monitoring module 2. The assembly component includes a first connecting plate 21, a second connecting plate 22, a first connecting block 23, a second connecting block 24, and a limiting rod 3. The connecting pipe 11 and the second connecting plate 22 are fixedly connected, and the first connecting plate 21 and the second connecting plate 22 are in close contact. The first connecting block 23 is symmetrically disposed on the first connecting plate 21, the second connecting block 24 is symmetrically disposed on the second connecting plate 22, and the limiting rod 3 is disposed on the corresponding first connecting block 23. The bottom of the limiting rod 3 is engaged with the second connecting block 24. In practical use, after aligning the first connecting plate 21 and the second connecting plate 22 at the bottom of the monitoring module 2, aligning the first connecting block 23 and the second connecting block 24, pressing the limiting rod 3 downward and rotating the limiting rod 3 to engage the bottom of the limiting rod 3 with the second connecting block 24, and then rotating and tightening the limiting rod 3, the assembly can be quickly achieved by pressing and rotating after alignment, thus avoiding the rusting problem of traditional fasteners. It is worth noting that a sealing gasket is provided between the first connecting plate 21 and the second connecting plate 22. The sealing gasket ensures the airtightness between the first connecting plate 21 and the second connecting plate 22 and avoids gas leakage at the connection point.

[0021] It is worth noting that monitoring module 2 includes an MCU, an SF6 multi-channel gas acquisition and switching circuit, and an active gas sampling device connected to it. The active gas sampling device is driven by an air pump and includes a sensor chamber with an integrated sensor, as well as multiple air guide tubes communicating with the sensor chamber. These multiple air guide tubes are connected to different monitoring points in the ring network cabinet, forming multiple sampling channels. Each air guide tube is equipped with a solenoid valve connected to the SF6 multi-channel gas acquisition and switching circuit. When the monitoring device is working, the MCU controls the multiple solenoid valves through the SF6 multi-channel gas acquisition and switching circuit. The valves are switched on and off in turn, causing the air pump to draw gas from different monitoring points into the sensor chamber to perform leak detection at multiple ring main unit monitoring points. The above device can detect the degree of SF6 gas leakage in the ring main unit or switch cabinet in the early stage of leakage, and then perform comprehensive analysis of SF6 pressure monitoring and ozone monitoring to make a preventive judgment on the health status inside the cabinet. Among them, the monitoring module 2 has been disclosed in the existing technology of online leakage, pressure and discharge monitoring device for SF6 gas in ring main units CN116678558A, and will not be described in detail here.

[0022] The first connecting block 23 is fixedly connected to the first connecting plate 21, the second connecting block 24 is fixedly connected to the second connecting plate 22, and the limiting rod 3 is movably connected to the first connecting block 23. Each first connecting block 23 is symmetrically provided with a support rod 33, each support rod 33 is fixedly connected to the corresponding first connecting block 23, and the corresponding first connecting block 23 is slidably connected with the same threaded ring 32. Each support rod 33 is fitted with a spring 34, and the end of each spring 34 is fixedly connected to the corresponding first connecting block 23 and the support rod 33. The limiting rod 3 and the threaded ring 32 are connected by threads, and the bottom of each limiting rod 3 is fixedly connected with an abutment block 31. The bottom of each second connecting block 24 is provided with a snap-fit ​​groove 5 and a through groove 51, which are staggered, and the corresponding abutment block 31 is snapped into the snap-fit ​​groove 5. Before the first connecting block 23 and the second connecting block 24 are aligned, the limiting rod 3 is manually rotated. The limiting rod 3 causes the abutment block 31 to align with the through groove 51, and then the first connecting block 23 and the second connecting block 24 are brought into tight contact. The abutment block 31 extends into the bottom of the second connecting block 24 through the through groove 51. Then, the limiting rod 3 is manually pressed down and rotated. After the limiting rod 3 causes the abutment block 31 to engage with the locking groove 5, the limiting rod 3 pushes down and drives the support rod 33. The support rod 33 drives the downward compression spring 34, which deforms and applies the deformation force to the support rod 33. The abutment block 31 at the bottom of the limiting rod 3 is aligned with the spring 34. Subsequently, the spring 34 pushes the threaded ring 32 upward through deformation force. The threaded ring 32 drives the abutment block 31 to be tightly engaged with the locking groove 5. Meanwhile, the limiting rod 3 and the threaded ring 32 are manually rotated to lower the threaded ring 32, thereby increasing the deformation degree of the compression spring 34 and increasing the locking force between the abutment block 31 and the locking groove 5. Through the limiting rod 3, the threaded ring 32, the spring 34 and the locking groove 5, the positioning, locking and fixing functions are achieved by pressing and rotating the limiting rod 3. This avoids the cumbersome installation caused by traditional fastener installation methods and the difficulty in removal due to rust, thus improving the installation and removal efficiency of this device.

[0023] Each of the first connecting blocks 23 is fixedly connected to a mounting block 4, each mounting block 4 is rotatably connected to a rotating rod 41, each rotating rod 41 is fixedly connected to a support block 42, and the end of each support block 42 abuts against the corresponding first connecting block 23 and threaded ring 32 respectively. After the first connecting block 23 and the second connecting block 24 are assembled, the limiting rod 3 is continuously rotated manually. The limiting rod 3 drives the threaded ring 32 downward through the thread. Before the threaded ring 32 descends to the bottom, the rotating rod 41 is rotated manually. The rotating rod 41 drives the support block 42 to be vertical, and the end of the support block 42 abuts against the first connecting block 23 and the threaded ring 32. This restricts the space between the threaded ring 32 and the first connecting block 23, preventing the limiting rod 3 from being pushed downward. It also restricts the abutment block 31 from being pushed upward against the locking groove 5, thus achieving stable locking of the device and preventing loosening between components, which could lead to unstable installation. One end of the support block 42 is an arc end, which allows the support block 42 to rotate and separate from the surface of the first connecting block 23. The other end of the support block 42 is flat, which allows the support block 42 to be tightly abutted against the threaded ring 32, ensuring the stability of the restriction.

[0024] Working principle: Before the first connecting block 23 and the second connecting block 24 are aligned, the limiting rod 3 is manually rotated. The limiting rod 3 causes the abutment block 31 to align with the through groove 51, and then the first connecting block 23 and the second connecting block 24 are brought into tight contact. The abutment block 31 extends into the bottom of the second connecting block 24 through the through groove 51. Then, the limiting rod 3 is manually pressed down and rotated. After the limiting rod 3 causes the abutment block 31 to engage with the locking groove 5, the limiting rod 3 pushes down and drives the support rod 33. The support rod 33 drives the downward compression spring 34, which deforms and applies the deformation force to the support rod 33. After the abutment block 31 at the bottom of the limiting rod 3 is aligned with the support rod 24, the spring 34 compresses downward. A variable force pushes the threaded ring 32 upward, causing the threaded ring 32 to tightly engage with the abutment block 31 and the locking groove 5. Meanwhile, a manual rotation of the limiting rod 3 and the threaded ring 32, after assembly between the first connecting block 23 and the second connecting block 24, continues the manual rotation of the limiting rod 3. The limiting rod 3, through its threads, drives the threaded ring 32 downward. Before the threaded ring 32 reaches its bottom, a manual rotation of the rotating rod 41 causes the support block 42 to become vertical, abutting the end of the support block 42 against the first connecting block 23 and the threaded ring 32. This restricts the space between the threaded ring 32 and the first connecting block 23, preventing the limiting rod 3 from pushing downward and restricting the abutment block 31 from moving upward between the abutment block 31 and the locking groove 5.
