Description

Technical Field

[0001] This utility model belongs to the field of gas leak detection technology, specifically relating to a gas leak detection device that incorporates geological structures. Background Technology

[0002] In soft geological environments, gas pipelines face a higher risk of leakage. Due to the instability of the soil, pipelines are easily affected by geological processes such as uneven settlement, lateral displacement, and soil creep. Uneven settlement may cause excessive local stress on the pipeline, resulting in pipeline deformation and rupture. Soil creep will continuously exert pressure on the pipeline, wear down the outer wall of the pipeline, and cause leakage under long-term action. Therefore, it is crucial to design a gas leak detection device that is integrated with the geological structure. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a gas leak detection device that incorporates geological structure to solve the problems in the background technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A gas leak detection device based on geological structure includes a first column and a second column. The lower ends of the first column and the second column are located in a hard layer, and the upper ends of the first column and the second column are located in a soft layer. A connecting plate is connected between the first column and the second column. A gas sensor is connected to the lower end of the connecting plate, and a gas pipeline is provided at the lower end of the gas sensor.

[0006] Preferably, both the first column and the second column are connected with a connecting ring.

[0007] Preferably, the lower ends of both the first and second columns are connected to geological detection sensors for geological testing.

[0008] Preferably, a reinforcing layer is connected to the outside of the gas pipeline, and the reinforcing layer is connected to the connecting ring.

[0009] Preferably, the connecting plate is connected to a connecting block, the inner side of the second column is provided with an installation groove, the inner side of the installation groove is slidably connected with a protrusion, the protrusion is connected with a spring, the inner side of the connecting block is provided with a limiting groove, and the protrusion and the limiting groove cooperate with each other.

[0010] Preferably, the gas sensor is connected to a display screen for displaying the position of the gas sensor.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. By setting up gas sensors, when a gas pipeline leaks, the gas will escape from the gaps in the reinforced layer, then float upwards in the soft layer, and be detected by the gas sensors, thus enabling the detection of the gas pipeline. Geological sensors can also be set up to collect geological information of each layer, and then compare it with the geological reconnaissance information before construction, so as to determine the changes in the geology and better predict the distribution of soil pressure in the geology, thereby enabling prevention as soon as possible.

[0013] 2. By setting a connecting block and a limiting groove, when the connecting block connected to the connecting plate enters the second column, the protrusion compresses the spring and moves upward under the action of the arc-shaped part at the front end of the connecting block. When the connecting block is completely inside the second column, the protrusion recovers under the elastic force of the spring, thereby entering the limiting groove on the connecting block to limit the connecting block, thereby improving the overall integrity of the device.

[0023] Example 1:

[0024] like Figure 1-4This invention discloses a gas leak detection device based on geological structure. The device includes a first column 3 and a second column 6. The lower ends of the first column 3 and the second column 6 are located in a hard layer 1 and fixed by friction. The upper ends of the first column 3 and the second column 6 are located in a soft layer 2. A connecting plate 5 connects the first column 3 and the second column 6. A gas sensor 7 is connected to the lower end of the connecting plate 5. A gas pipeline 4 is located below the gas sensor 7. Both the first column 3 and the second column 6 are connected to connecting rings 8. A reinforcing layer 15 is connected to the outside of the gas pipeline 4 and is connected to the connecting rings 8. The reinforcing layer 15 reduces friction between the soil layer and the gas pipeline 4. Because the connecting rings 8 are fixedly connected to the reinforcing layer 15, even if the soft layer 2 slips, the first column 3 and the second column 6, fixedly connected to the connecting rods 8, can still provide some support, preventing the gas pipeline 4 from breaking due to lateral force. The lower ends of the first column 3 and the second column 6 are both connected to connecting rings 8. A geological detection sensor 16 is connected for geological testing. The geological detection sensor 16 detects the soil layer from bottom to top. A connecting plate 5 is connected to a connecting block 9. The inner side of the second column 6 is provided with an installation groove 11. A protrusion 10 is slidably connected to the inner side of the installation groove 11. A spring 12 is connected to the protrusion 10. A limiting groove 13 is provided on the inner side of the connecting block 9. The protrusion 10 and the limiting groove 13 cooperate with each other. When the connecting block 9 connected to the connecting plate 5 enters the second column 6, the protrusion 10 compresses the spring 12 and moves upward under the action of the arc-shaped part at the front end of the connecting block 9. When the connecting block 9 is completely inside the second column 6, the protrusion 10 returns to its original position under the elastic force of the spring 12, thereby limiting the connecting block 9 in the limiting groove 13 on the connecting block 9. This improves the overall integrity of the device and allows the first column 3, the second column 6 and the connecting plate 5 to be transported and installed separately, making transportation easier. A display screen 14 is connected to the gas sensor 7 to display the position of the gas sensor 7.

[0025] Working principle:

[0026] Staff send a start command to the target sensor via a remote control platform. This command carries a unique identifier, CMD-START, containing the IDs of gas sensor 7 and geological detection sensor 16, a start timestamp, and an encrypted verification code to ensure accurate delivery. Upon receiving the CMD-START signal, gas sensor 7 and geological detection sensor 16 immediately initiate a hardware self-test program, performing status checks on core components such as the power module, detection sensors, communication module, and geological data acquisition unit. After passing the self-test, a CHECK-OK signal is automatically generated, indicating a ready-to-start state. Based on preset geological region parameters, geological detection sensor 16 activates its geological structure data acquisition module, collecting key data such as stratum number, soil permeability, rock fissure distribution, and groundwater depth at its location. These data are integrated into signal marker GEO-DATA-1, laying the foundation for subsequent geological comparison. Simultaneously, gas sensor 7 begins real-time monitoring of the gas content in the surrounding environment, updating data every 3 seconds and generating signal marker GAS-CONC-2, which includes real-time concentration values, latitude and longitude coordinates of the detection point, and data acquisition time. Then, the data carried by GEO-DATA-1 and GAS-CONC-2 signals are fused and preprocessed. The processed data is packaged into signal marker PACK-DATA-3 and then transported to the remote control platform. The remote control platform compares the geological graphic data from geological detection sensor 16 with the geological graphic data detected after construction, thereby deduce information such as geological flow and analyze the stress distribution of the soil layer for timely prevention. If the gas data exceeds a set threshold, signal marker ALARM-6 is triggered, thereby reducing the collection time of gas sensor 6 and marking the specific location of gas sensor 6 on the display screen, making it convenient for staff to pinpoint the leak location.
