Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas pipeline technology, and in particular to a stray current monitoring device for gas pipelines. Background Technology
[0002] Gas pipelines refer to pipelines primarily used for transporting natural gas, liquefied petroleum gas, and manufactured gas. In long-distance transportation, gas pipelines specifically refer to those transporting natural gas. In urban areas, they refer to those transporting natural gas, liquefied petroleum gas, and manufactured gas, among other media. Due to the special nature of their transport, pipeline materials used in gas pipelines exposed to the elements for extended periods are prone to generating stray currents, requiring monitoring to prevent safety accidents.
[0003] In existing gas pipeline monitoring devices, the device is connected to the pipeline using a current line. As a result, the installation stability of the gas pipeline monitoring device is generally poor, which also leads to errors in the gas pipeline monitoring, reduces the monitoring efficiency of the gas pipeline, and may cause injury to operators, posing a safety hazard. Therefore, we propose a stray current monitoring device for gas pipelines. Utility Model Content
[0004] The purpose of this utility model is to provide a stray current monitoring device for gas pipelines, in order to solve the problems mentioned in the background art, in which the existing gas pipeline monitoring devices are connected to the pipeline by current lines, resulting in poor installation stability, easy errors in gas pipeline monitoring, reduced monitoring efficiency, and potential harm to operators, thus posing safety hazards.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a stray current monitoring device for gas transmission pipelines, including a current monitoring device body and a second mounting ring, and further including: a first mounting ring disposed on the outside of the current monitoring device body; a mounting mechanism: the mounting mechanism includes a shaft disposed inside the first mounting ring, a limit component disposed inside the second mounting ring, and a protective component disposed inside the current monitoring device body.
[0007] Furthermore, the limiting component includes a placement groove disposed inside the second mounting ring, a placement block disposed outside the first mounting ring, a slot being formed inside the placement block, a hollow groove being formed on the inner side wall of the placement groove, a return spring being disposed on the inner side wall of the hollow groove, a locking post being disposed inside the hollow groove, a limiting groove being formed on the outer wall of the locking post, a limiting block being disposed on the inner wall of the hollow groove, and a pull rod being disposed at one end of the locking post.
[0008] Furthermore, the protective component includes a through groove disposed inside the current monitoring device body, an operating button disposed on the outside of the current monitoring device body, a limit rod disposed on the inner bottom wall of the through groove, a connecting block disposed on the outside of the limit rod, a protective cover disposed on the outside of the connecting block, and a handle disposed on the outside of the protective cover.
[0009] Furthermore, the second mounting ring is rotatably connected to the first mounting ring via a shaft, and the width of the placement block matches the width of the placement groove.
[0010] Furthermore, the placement block and the locking post are arranged parallel to each other, and the locking post and the empty slot are slidably connected.
[0011] Furthermore, the locking post and the locking groove are locked in place by an engaging mechanism, while the limiting block and the limiting groove are slidably connected.
[0012] Furthermore, the connecting block and the limiting rod are slidably connected, and the protective cover and the current monitoring device body are arranged parallel to each other.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] This utility model includes an installation mechanism. By pulling the lever, the sliding lever causes the locking pin to slide inside the slot, thereby causing the limiting block to slide inside the limiting slot. Simultaneously, the sliding locking pin slides and compresses the return spring, causing the first mounting ring to rotate via the shaft, covering the outside of the gas pipeline. The rotating first mounting ring then causes the placement block to insert into the placement slot. Releasing the lever allows the locking pin to slide back to its original position via the return spring, thus engaging and fixing the sliding locking pin and the slot. Pulling the handle upwards causes the handle to slide, causing the protective cover to slide against the outer wall of the limiting rod. Simultaneously, the sliding connecting block compresses and buffers the telescopic spring, facilitating operation of the external control buttons on the current monitoring device body. This facilitates stable installation of the stray current monitoring device, improves its operational stability, and avoids the cumbersome installation and reduced operational stability that can occur when the pipeline material is used outdoors for extended periods due to the special nature of the transport process.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0025] Please see Figure 1-4As shown, this embodiment is a stray current monitoring device for gas transmission pipelines, including a current monitoring device body 1 and a second mounting ring 6, and further including: a first mounting ring 2 is provided on the outside of the current monitoring device body 1; the mounting mechanism includes a shaft 3 provided inside the first mounting ring 2, a limit component is provided inside the second mounting ring 6, and a protective component is provided inside the current monitoring device body 1.
[0026] As the main load-bearing structure, the installation mechanism can increase the ease of installation of the overall structure by being fixedly connected to the device.
[0027] The limiting component includes a placement groove 7 disposed inside the second mounting ring 6, a placement block 4 disposed outside the first mounting ring 2, a slot 5 disposed inside the placement block 4, a hollow groove 8 disposed on the inner side wall of the placement groove 7, a return spring 9 disposed on the inner side wall of the hollow groove 8, a locking post 10 disposed inside the hollow groove 8, a limiting groove 11 disposed on the outer wall of the locking post 10, a limiting block 12 disposed on the inner wall of the hollow groove 8, and a pull rod 13 disposed at one end of the locking post 10.
[0028] By setting a limiting component, it is easy to pull the lever 13 so that the sliding lever 13 drives the locking pin 10 to slide inside the slot 8, thereby allowing the limiting block 12 to slide inside the limiting slot 11. At the same time, the sliding locking pin 10 slides and squeezes the return spring 9, causing the first mounting ring 2 to rotate through the shaft 3, so that the first mounting ring 2 covers the outside of the gas pipeline. The rotating first mounting ring 2 drives the placement block 4 to insert into the placement slot 7. At the same time, the lever 13 is released, allowing the locking pin 10 to slide and reset through the return spring 9, thereby locking and fixing the sliding locking pin 10 and the slot 5.
[0029] The protective components include a through groove 15 disposed inside the current monitoring device body 1, an operating button 14 disposed on the outside of the current monitoring device body 1, a limit rod 16 disposed on the inner bottom wall of the through groove 15, a connecting block 17 disposed on the outside of the limit rod 16, a protective cover 19 disposed on the outside of the connecting block 17, and a handle 20 disposed on the outside of the protective cover 19.
[0030] By setting up protective components, it is easy to pull the handle 20 upwards, so that the handle 20 drives the protective cover 19 to slide. The sliding protective cover 19 then slides on the outer wall of the limit rod 16. At the same time, the sliding connecting block 17 squeezes and buffers the telescopic spring 18, making it easy for people to operate the operating button 14 on the outside of the current monitoring device body 1.
[0031] Working principle: By pulling the lever 13, the sliding lever 13 causes the locking pin 10 to slide inside the slot 8, thereby causing the limiting block 12 to slide inside the limiting slot 11. At the same time, the sliding locking pin 10 slides and compresses the reset spring 9, causing the first mounting ring 2 to rotate through the shaft 3, so that the first mounting ring 2 covers the outside of the gas pipeline. The rotating first mounting ring 2 causes the placement block 4 to be inserted into the placement slot 7. At the same time, the lever 13 is released, causing the locking pin 10 to slide and reset through the reset spring 9, thereby locking and fixing the sliding locking pin 10 and the slot 5. At the same time, the handle 20 is pulled upward, causing the handle 20 to drive the protective cover 19 to slide. The sliding protective cover 19 slides on the outer wall of the limiting rod 16. At the same time, the sliding connecting block 17 compresses and buffers the telescopic spring 18, making it easy for people to operate the operating button 14 on the outside of the current monitoring device body 1. After use, the above reverse steps can be applied directly.
[0032] This step facilitates the stable installation of the stray current monitoring device, improves its operational stability, and avoids the cumbersome installation process and reduced operational stability that can occur if the pipeline materials used for transportation are exposed to the elements for extended periods.
