Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline safety management technology, specifically relating to an external monitoring device for gas pipelines that is easy to install. Background Technology

[0002] Urban gas pipelines transport natural gas from gas transmission pipelines or other gas supply sources to residential, commercial, and industrial users within a city. They can be further divided into distribution pipelines, user inlet pipes, and indoor gas pipelines. External gas pipeline detection devices are mainly for leak detection and early warning: that is, real-time monitoring of the concentration of combustible gas in the environment surrounding the gas pipeline. Once a gas leak is detected, an alarm can be issued quickly to remind relevant personnel to take timely measures to prevent serious safety accidents such as explosions and fires, and to protect people's lives and property and public safety.

[0003] External detection devices require a mounting bracket or base. Use tools such as screwdrivers, wrenches, or drills to secure the bracket or base to the selected installation location. For wall mounting, use expansion bolts to firmly fix the bracket or base to the wall; for pipe mounting, ensure the clamp fits tightly against the pipe and tighten with bolts.

[0004] Problems with existing technology:

[0005] When using the above-mentioned pipe clamping installation method, multiple bolts need to be tightened, which makes installation or disassembly cumbersome and inconvenient. Therefore, this utility model proposes an external gas pipeline monitoring device that is easy to install. Utility Model Content

[0006] The purpose of this invention is to provide an external monitoring device for gas pipelines that is easy to install and can solve the above-mentioned technical problems.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] This utility model provides an external gas pipeline monitoring device that is easy to install, including a support mechanism, a snap-fit ​​mechanism, and a clamping mechanism. The support mechanism is positioned to hug the installed gas pipeline through the snap-fit ​​mechanism. The clamping mechanism limits and fixes the support mechanism and the snap-fit ​​mechanism. The detection device body is provided on the clamping mechanism.

[0009] The support mechanism includes a bottom clamping plate and a stabilizing clamping plate that hug the gas pipeline. Two fixed plates are provided on both sides of the bottom clamping plate. Two movable seats are provided on each of the two fixed plates. Two flip plates are movably provided on each of the two movable seats. Two second vertical support plates are provided on each of the two flip plates. The lower sides of the two flip plates are slidably fitted into two movable frames. Two extension plates are provided on each of the two movable frames. Two extension plates are provided on both sides of the stabilizing clamping plate. Two first vertical support plates are provided on each of the two extension plates.

[0010] The snap-fit ​​mechanism includes a support frame that is symmetrically attached to the gas pipeline with the bottom snap plate. An arc-shaped mesh is provided inside the support frame. Snap-fit ​​plates are provided on both sides of the support frame. The two flip plates are respectively snapped into the two snap-fit ​​plates.

[0011] Preferably, the clamping mechanism includes a top frame, and overlapping plates that overlap and support the top frame are provided on the upper sides of the two first vertical support plates and the two second vertical support plates. The top frame is provided with two plug-in frames and two clamping plates, and the two plug-in frames and the two clamping plates are respectively provided on the four overlapping plates.

[0012] Preferably, two inner clip plates are provided on opposite sides of the top frame. The two clip plates are respectively inserted into the clip holes formed between the two inner clip plates and the inside of the top frame. Two mounting plates are provided inside the top frame. The detection equipment body is detachably mounted on the two mounting plates. The opposite sides of the two mounting plates are respectively provided with wire mesh frames that are connected to the inner side of the top frame.

[0013] Preferably, the bottom surface of the top frame is provided with a vertical plate, and a lower top plate is provided on the lower side of the vertical plate, which is locked onto the support frame and the arc-shaped net. Two pushing mechanisms are provided inside the top frame.

[0014] Preferably, the pushing mechanism includes a smooth plate, and two sets of sliding holes are formed on the top frame. The smooth plate is slidably disposed in one set of sliding holes. Limiting frames that engage with the sides of the top frame are respectively provided on both sides of the smooth plate. Two sets of pushing springs are provided inside the top frame. The smooth plate is located on one side of the wire mesh frame, and the pushing springs are disposed between the smooth plate and the wire mesh frame.

[0015] Preferably, the smooth plate is provided with a push plate and a plug plate on its side, the push plate is horizontally corresponding to the trip plate, the plug plate is plugged into the plug frame, and the smooth plate is provided with ear plates on both the upper and lower sides.

[0016] The aforementioned easy-to-install external gas pipeline monitoring device involves the following steps: First, place the support frame and arc-shaped mesh on the clamping mechanism onto the gas pipeline. Then, overlap the flipping plate and buckle plate on the support mechanism, ensuring the bottom clamping plate contacts the outer surface of the gas pipeline. Next, flip the second vertical support plate, causing it to rotate against the movable seat. Simultaneously, the flipping plate presses down on the buckle plate, ensuring the support plate fully contacts the outer surface of the gas pipeline. As the flipping plate rotates, the first vertical support plate on the outer extension plate rotates to be perpendicular to the gas pipeline, while the second vertical support plate becomes vertically parallel to the first. Finally, overlap the top frame on the clamping mechanism. On the overlapping plate, pull the smooth plates on the two pushing mechanisms closer together, thereby causing the plug-in plate and the pushing plate to move away from the contact with the clamping plate and the plug-in frame, so that the clamping plate and the plug-in frame are located inside the top frame. At the same time, the lower top plate is also attached to the support frame and the arc-shaped net. Then, release the ear plate, so that the pushing spring pushes the smooth plate to move in the opposite direction, and at the same time, it drives the pushing plate to push the clamping plate and the second vertical plate to move synchronously, thereby causing the flipping plate to slide in the movable frame. At the same time, the clamping plate also slides and gets stuck in the locking hole between the inner locking plate and the top frame. At the same time, the plug-in plate also moves and inserts into the plug-in frame. In this way, the support mechanism and the locking mechanism can be clamped and pushed at the same time, thereby installing and fixing the detection equipment body on the mounting plate on the top frame.

[0017] The beneficial effects are:

[0018] This utility model uses a support mechanism and a snap-fit ​​mechanism to position and clamp the gas pipe. Then, the snap-fit ​​mechanism can clamp and restrict the support mechanism, while simultaneously tightening the snap-fit ​​mechanism. Thus, while clamping the support mechanism, a support restriction is formed simultaneously. This allows the detection equipment body on the snap-fit ​​mechanism to be conveniently installed on the gas pipeline, thereby improving the ease of installation and facilitating easy disassembly and maintenance later.

Detailed Implementation

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5 As shown, an external gas pipeline monitoring device that is easy to install includes a support mechanism 1, a snap-fit ​​mechanism 2 and a clamping mechanism 3. The support mechanism 1 is positioned with the installed gas pipeline by snap-fit ​​mechanism 2. The clamping mechanism 3 limits and fixes the support mechanism 1 and the snap-fit ​​mechanism 2. The detection device body 4 is provided on the clamping mechanism 3.

[0028] The support mechanism 1 includes a bottom clamping plate 101 and a stabilizing clamping plate 102 that are attached to the gas pipeline. Both the bottom clamping plate 101 and the stabilizing clamping plate 102 are semi-circular in shape. Two fixed plates 103 are provided on both sides of the bottom clamping plate 101. Two movable seats 104 are provided on each of the two fixed plates 103. Two flip plates 105 are movably mounted on each of the two movable seats 104. Both flip plates 105 are L-shaped. Two second vertical support plates 109 are provided on each of the two flip plates 105. The lower side of the two flip plates 105 is slidably fitted into two movable frames 106. A baffle for limiting the sliding and disengagement of the movable frames is provided on the lower side of the two flip plates 105. The two movable frames 106 are provided with an extension plate 107. The two extension plates 107 are provided on both sides of the stabilizing clamping plate 102. Two first vertical support plates 108 are provided on each of the two extension plates 107.

[0029] The snap-fit ​​mechanism 2 includes a support frame 201 that is symmetrically attached to the gas pipeline with the bottom snap plate 101. An arc-shaped mesh 202 is provided inside the support frame 201. A snap-fit ​​plate 203 is provided on both sides of the support frame 201. The snap-fit ​​plate 203 is provided with an L-shaped hole with an opening, so that after the flip plate 105 moves, it can be snapped into the L-shaped hole to restrict its up and down movement. The two flip plates 105 are respectively snapped into the two snap-fit ​​plates 203.

[0030] As an optional implementation, the clamping mechanism 3 includes a top frame 31. The upper sides of the two first vertical support plates 108 and the two second vertical support plates 109 are provided with overlapping plates 110 to support the top frame 31. The top frame 31 is provided with two insertion frames 111 and two clamping plates 112. The two insertion frames 111 and the two clamping plates 112 are respectively set on the four overlapping plates 110. In this way, the overlapping frames can be supported by the first vertical support plates 108 and the second vertical support plates 109, so that the top frame 31 carrying the detection equipment is at a certain distance from the gas pipeline, which is convenient to meet the installation requirements.

[0031] See attached document Figure 4 Two inner clamping plates 34 are provided on opposite sides inside the top frame 31. Two clamping plates 112 are respectively inserted into the clamping holes formed between the two inner clamping plates 34 and the inside of the top frame 31. Two mounting plates 37 are provided inside the top frame 31. The detection equipment body 4 is detachably mounted on the two mounting plates 37. The opposite sides of the two mounting plates 37 are respectively provided with wire mesh frames 38 that are connected to the inner side of the top frame 31. This arrangement can create airflow around the detection equipment body 4, thereby improving the detection effect of the detection equipment body 4 on the gas pipeline.

[0032] Furthermore, a vertical plate 35 is provided on the bottom surface of the top frame 31, and a lower top plate 36 is provided on the lower side of the vertical plate 35, which is clamped on the support frame 201 and the arc-shaped mesh 202. Two pushing mechanisms 33 are provided inside the top frame 31. The lower top plate 36 is set in an arc shape that fits into the outer peripheral surface of the support frame 201. With this setting, the lower top plate 36 on the vertical plate 35 can be used to press down on the support frame 201 and the arc-shaped plate against the gas pipeline, thereby tightening the clamping mechanism 2 and restricting its upward flipping.

[0033] See attached document Figure 5The pushing mechanism 33 includes a smooth plate 331. Two sets of sliding holes 32 are formed on the top frame 31. The smooth plate 331 is slidably disposed in one set of sliding holes 32. Restriction frames 335 that engage with the sides of the top frame 31 are respectively provided on both sides of the smooth plate 331. Two sets of pushing springs 332 are provided inside the top frame 31. The smooth plate 331 is located on one side of the wire mesh frame 38. The pushing springs 332 are disposed between the smooth plate 331 and the wire mesh frame 38. This arrangement allows the pushing springs 332 to continuously push the smooth plate 331 closer to the inner side of the top frame 31, thereby driving the pushing plate 333 to push the retaining plate 112, causing the retaining plate 112 to slide and engage in the retaining hole between the inner retaining plate 34 and the top frame 31, thus forming a sleeve on the retaining plate 112 and restricting its vertical movement.

[0034] Furthermore, the smooth plate 331 is provided with a push plate 333 and a plug-in plate 334 on its side. The push plate 333 is horizontally corresponding to the trip plate 112, and the plug-in plate 334 is plugged into the plug-in frame 111. The upper and lower sides of the smooth plate 331 are provided with ear plates 336. In this way, after the plug-in plate 334 is plugged into the plug-in frame 111, it forms a locking restriction on the first vertical support plate 108 and the top frame 31, thereby improving the support effect on the first vertical support plate 108.

[0035] Using the above structure, during installation, first place the support frame 201 and arc-shaped mesh 202 on the clamping mechanism 2 onto the gas pipeline. Then, overlap the flip plate 105 on the support mechanism 1 with the buckle plate 203. At the same time, the bottom clamping plate 101 on the support mechanism 1 contacts the outer surface of the gas pipeline. Then, flip the second vertical support plate 109 to drive the flip plate 105 to flip against the movable seat 104. At the same time, when the flip plate 105 flips, it presses down on the buckle plate 203, thereby driving the support plate to fully compress and contact the outer surface of the gas pipeline. As the flip plate 105 flips, it drives the first vertical support plate 108 on the extension plate 107 to flip and become perpendicular to the gas pipeline. At the same time, the second vertical support plate 109 is also vertically parallel to the first vertical support plate 108. Then, the top frame 31 on the clamping mechanism 3 overlaps on the overlapping plate 110, and pulls the two pushing mechanisms 33. The smooth plates 331 move closer to each other, thereby causing the plug-in plate 334 and the push plate 333 to move away from the contact of the trip plate 112 and the plug-in frame 111, so that the trip plate 112 and the plug-in frame 111 are located inside the top frame 31. At the same time, the lower top plate 36 is also attached to the support frame 201 and the arc mesh 202. Then the ear plate 336 is released, so that the push spring 332 pushes the smooth plate 331 to move in the opposite direction, while driving the push plate 333 to push the trip plate 112 and the second vertical plate 35 to move synchronously, thereby driving the flip plate 105 to slide in the movable frame 106. At the same time, the trip plate 112 also slides and gets stuck in the card hole between the inner card plate 34 and the top frame 31. At the same time, the plug plate 334 also moves and inserts into the plug-in frame 111. In this way, the support mechanism 1 and the carding mechanism 2 can be tripped and pushed at the same time, thereby installing and fixing the detection equipment body 4 on the mounting plate 37 on the top frame 31.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
