Abstract
Description
Technical Field
[0001] This utility model relates to the field of marker post technology, specifically to a gas pipeline leak detection marker post. Background Technology
[0002] Currently, underground gas leak detection is usually carried out according to the pipeline inspection plan. Gas detection instruments (handheld and vehicle-mounted) are used to check for gas leaks from underground gas pipelines along the gas pipeline route and surrounding pressure regulating equipment in order to find out if there is a gas leak in the underground gas pipeline.
[0003] Horizontal gas pipelines typically use PE pipes or steel-reinforced pipes, which have strong corrosion resistance. Longitudinal gas pipelines, on the other hand, usually use seamless steel pipes, which have relatively weaker corrosion resistance, especially at the joints and transition points between different materials, where corrosion and leakage are prone to occur. Current leak detection methods do not specifically target the weak points in corrosion resistance at the transverse and longitudinal joints; they are mainly scanning-based. If a leak is minor in its early stages, the small volume and easy dispersion of the gas can make it undetectable. For underground gas pipelines, due to their deep burial depth (80cm-120cm or more), it takes time for the gas to seep to the surface, and the leak volume needs to reach a certain concentration before it can be detected by instruments on the surface. Furthermore, leaks are often interfered with by other gases (such as biogas and easily detectable gases from paint fumes), making it difficult to proactively detect and resolve leaks in underground gas pipelines immediately. Gas leaks in underground pipelines can easily accumulate, creating secondary risks. Because the density of natural gas is less than that of air, it is prone to gas migration, accumulation in wells and trenches, and even deflagration when exposed to an open flame within the explosive limits. However, existing technologies have too long detection cycles, and without any preparatory or auxiliary detection methods, they cannot accurately detect underground gas pipeline leaks in a short period of time, and cannot proactively eliminate potential hazards in their infancy. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a gas pipeline leak detection marker post.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0029] Compared with the prior art, the beneficial effects of this utility model are:
[0030] 1. This utility model, by setting an access hole and a gas collection pipe, allows the leaked gas to enter the connecting pipe from the gas collection pipe when a gas pipeline leaks, and then enter the marker post body from the connecting pipe. A gas detection instrument is connected to the access hole to detect the gas leak, and can accurately detect underground gas pipeline leakage in a short time.
[0031] 2. This utility model, by setting up an installation mechanism, when the knob is turned, drives the threaded rod to rotate, causing the second clamping plate to slide in the groove. This allows the second clamping plate to cooperate with the first clamping plate to abut against both sides of the gas pipeline and clamp onto the gas pipeline, thereby realizing the installation of the marker post body on the gas pipeline and preventing the marker post body from shaking or tipping over.
[0032] 3. This utility model, by setting an adjustment component, rotates the threaded column, causing the threaded column to move vertically within the sleeve, thereby adjusting the height of the marker post body to adapt to gas pipelines buried at different depths;
[0033] 4. By setting a water outlet, when there is water accumulation in the space where the gas pipeline is located, the water will enter the marker post body. If there is too much water, it will rush to the access hole, thereby damaging the gas detection instrument connected to the access hole and avoiding affecting the detection results. When the bottom of the marker post body is provided with a water outlet, the water will be discharged from the water outlet, eliminating the potential hazard. Attached Figure Description

[0040] Access hole 4 is located on the top of the marker post body 1 and is used to connect a gas detection instrument;
[0041] The installation mechanism is located below the connecting pipe 6 and is used to install the marker post body 1.
[0042] With this design, the connecting pipe 6 is connected to the gas collecting pipe 7, the marker post body 1 is located above ground, the connecting pipe 6 is buried underground, the gas collecting pipe 7 is located in the space where the gas pipe is located, and the marker post body 1 is a hollow structure. When the gas pipe leaks, the leaked gas enters the connecting pipe 6 from the gas collecting pipe 7, and then enters the marker post body 1 from the connecting pipe 6. The gas detection instrument is connected to the access hole 4 to detect the gas leak and accurately detect the underground gas pipeline leakage in a short time.
[0043] In one embodiment, the lower end of the connecting pipe 6 is provided with an adjustment component for adjusting the height of the marker post body 1;
[0044] The adjustment components include:
[0045] Threaded post 8 is located at the lower end of connecting pipe 6;
[0046] Sleeve 9 is located below threaded post 8 and is sleeved on threaded post 8, and is threadedly connected to threaded post 8.
[0047] With this design, the threaded post 8 is rotatably connected to the bottom end of the connecting pipe 6; rotating the threaded post 8 causes it to move vertically within the sleeve 9, thereby adjusting the height of the marker post body 1 to accommodate gas pipelines buried at different depths.
[0048] In one embodiment, the mounting mechanism includes:
[0049] Support plate 10 is located at the lower end of sleeve 9;
[0050] The first clamping plate 12 is connected to the lower end of the support plate 10;
[0051] The second clamping plate 17 is slidably disposed at the lower end of the support plate 10;
[0052] The power unit is mounted on the support plate 10.
[0053] With this design, the support plate 10 is fixedly connected to the lower end of the sleeve 9; the first clamping plate 12 is fixedly connected to the lower end of the support plate 10.
[0054] In one embodiment, the power assembly includes:
[0055] An extension plate 11 is provided on the support plate 10 on one side near the second clamping plate 17;
[0056] The slide groove 15 is provided at the bottom end of the support plate 10 and is used for sliding the second clamping plate 17.
[0057] A rotating component is provided on the second clamping plate 17 and is used to drive the second clamping plate 17 to rotate.
[0058] With this design, the extension plate 11 is fixedly connected to one side of the support plate 10.
[0059] In one embodiment, the rotating member includes:
[0060] The threaded rod 14 is rotatably mounted on the extension plate 11 and the second clamping plate 17;
[0061] A slide bar 13 is located at one end of the threaded rod 14 and is rotatably connected to the first clamping plate 12;
[0062] Knob 16 is located at the end of threaded rod 14 away from slide rod 13.
[0063] With this design, one end of the threaded rod 14 is fixedly connected to the slide rod 13, and the other end is fixedly connected to the knob 16. When the knob 16 is rotated, the threaded rod 14 is rotated, causing the second clamping plate 17 to slide in the slide groove 15. This allows the second clamping plate 17 to cooperate with the first clamping plate 12 to abut against both sides of the gas pipeline and clamp onto the gas pipeline, thereby enabling the installation of the marker post body 1 on the gas pipeline and preventing the marker post body 1 from shaking or tipping over.

[0065] With this design, when there is water accumulation in the space where the gas pipeline is located, the water will enter the marker post body 1. If there is too much water, it will rush to the access hole 4, thereby damaging the gas detection instrument connected to the access hole 4 and avoiding affecting the detection results. When the bottom of the marker post body 1 is provided with a water outlet hole 5, the water will be discharged from the water outlet hole 5, eliminating the potential hazard.
[0066] In one embodiment, the marker post body 1 is also provided with an indicator light 2.

[0068] In one embodiment, a solar panel 3 is provided at the top of the marker post body 1.
[0069] With this design, the solar panel 3 stores electricity for the indicator light 2 and the gas detection instrument.
[0070] Working principle: In use, when a gas pipeline leaks, the leaking gas enters the connecting pipe 6 from the gas collecting pipe 7, and then enters the marker post body 1 from the connecting pipe 6. The gas detection instrument is connected to the access hole 4 to detect the gas leak, accurately detecting underground gas pipeline leaks in a short time. Rotating the threaded column 8 causes the threaded column 8 to move vertically in the sleeve 9, thereby adjusting the height of the marker post body 1 to accommodate gas pipelines buried at different depths. When the knob 16 is rotated, the threaded rod 14 rotates, causing the second clamping plate 17 to slide in the groove 15, thereby allowing the second clamping plate 17 to cooperate with the first clamping plate 12 to abut against the gas. The marker post body 1 is clamped to both sides of the gas pipeline to prevent it from shaking or tipping over. When there is water in the space where the gas pipeline is located, the water will enter the marker post body 1. If there is too much water, it will rush to the access hole 4, thereby damaging the gas detection instrument connected to the access hole 4 and affecting the detection results. When the bottom of the marker post body 1 is equipped with a water outlet hole 5, the water will be discharged from the water outlet hole 5 to eliminate the potential hazard. The design of the indicator light 2 indicates the presence of the marker post body 1 to passersby, solving the problem of not being able to see the marker post at night. The solar panel 3 stores electricity for the indicator light 2 and the gas detection instrument.
