Description

Technical Field

[0001] This utility model relates to the field of pipeline leakage technology, specifically to a real-time detection and alarm mechanism for underground pipeline network leakage. Background Technology

[0002] Natural gas is a clean energy source with high safety during use. It is usually transported through pipelines. With the acceleration of urbanization and the continuous growth of energy demand, the underground gas pipeline network is becoming increasingly large and complex. While gas, as a clean energy source, brings convenience to people's lives and production, its safe transportation and use also face many challenges. Among these challenges, gas pipeline leak detection is a key link in ensuring gas safety.

[0003] With the continuous construction of underground pipeline networks, the maintenance of gas pipelines has become of paramount importance. In order to better detect pipeline leaks, fiber optic sensors are used to monitor pipeline vibration signals, enabling real-time monitoring within a 40-kilometer range. However, the fiber optic sensors need to be fixed with clips to prevent them from falling off the outer wall of the pipeline.

[0004] Therefore, we propose a real-time detection and alarm mechanism for underground pipeline leaks. Utility Model Content

[0005] The purpose of this invention is to provide a real-time detection and alarm mechanism for underground pipeline leaks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a real-time detection and alarm mechanism for underground pipeline leaks, comprising a fixed base, a top-out groove in the center of the fixed base, sliding grooves on both sides of the top-out groove inside the fixed base, a sliding block movably connected inside the sliding groove, a threaded rod rotatably connected to the fixed base inside the sliding groove, a connecting block fixedly installed at the bottom of the sliding block, a movable plate slidably connected inside the top-out groove, a clamping spring above the movable plate inside the top-out groove, a connecting rod integrally connected to the bottom of the movable plate, a sensor body fixedly installed at the bottom of the connecting rod to abut against the outer wall of the pipeline, transmission optical fibers connecting other sensor bodies to both ends of the sensor body, a hexagonal groove at one end of the threaded rod, the threaded rod being threadedly connected to the top of the connecting block, and a clamping claw at the bottom of the connecting block.

[0007] Optionally, the two sliding grooves are symmetrically arranged with the center of the ejection groove as the center of symmetry, and a fixing plate is fixedly installed at the bottom of the connecting block, and the grippers are fixedly installed on both sides of the bottom of the fixing plate.

[0008] Optionally, the top of the fixing plate slides in contact with the bottom of the fixing seat, one end of the top of the fixing plate is fixedly installed with the connecting block, and the other end of the top of the fixing plate is provided with a connecting groove, which slides in contact with the bottom of another connecting block.

[0009] Optionally, a fixing slot is provided on one side of the fixing base, and a gas detector is fixedly installed on one side of the fixing base through the fixing slot. A sensor group located behind the gas detector is also fixedly installed on one side of the fixing base.

[0010] Optionally, the sensor group includes a temperature sensor and a vibration sensor.

[0011] Optionally, the connecting block is L-shaped and placed horizontally, and the threaded rod is threadedly connected to the portion of the connecting block that is higher than the sliding block.

[0012] Optionally, a limiting groove is provided on the inner wall of the ejector groove, and limiting sliders are integrally connected to both sides of the movable plate. The limiting sliders are slidably connected to the inside of the limiting groove, and the bottom of the clamping spring is clamped to the top of the movable plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This underground pipeline leak real-time detection and alarm mechanism uses clamps. The clamps are placed on both sides of the pipeline. Rotating the hexagonal groove causes the threaded rod to rotate, which in turn causes the connecting block to drive the sliding block and the fixing plate to move along the sliding groove towards the center of the fixing seat. This clamps the clamps with both sides of the pipeline, thus fixing the fixing seat and the sensor body to the pipeline and preventing the sensor body from falling off.

[0014] This underground pipeline leak real-time detection and alarm mechanism, through the setting of a top-out groove, when the clamping claw is clamped with the pipeline, under the action of the clamping spring, the movable plate pushes the connecting rod down, pressing the sensor body against the outer wall of the pipeline, ensuring that the fiber optic sensor is firmly fixed and preventing the fiber optic sensor from falling off the outer wall of the pipeline.

[0018] Please see Figures 1 to 4 This utility model provides a real-time detection and alarm mechanism for underground pipeline leaks, including a fixed base 1. A top-out groove 2 is formed in the center of the fixed base 1. Sliding grooves 3 are formed on both sides of the top-out groove 2 inside the fixed base 1. Sliding blocks 9 are movably connected inside the sliding grooves 3. A threaded rod 10 is rotatably connected to the fixed base 1 inside the sliding grooves 3. A connecting block 12 is fixedly installed at the bottom of the sliding block 9. A movable plate 5 is slidably connected inside the top-out groove 2. A clamping spring 4 is provided inside the top-out groove 2 above the movable plate 5. A connecting rod 6 is integrally connected to the bottom of the movable plate 5. A sensor that abuts against the outer wall of the pipeline is fixedly installed at the bottom of the connecting rod 6. The sensor body 7 has transmission optical fibers 8 at both ends that connect to other sensor bodies 7. One end of the threaded rod 10 has a hexagonal groove 11. The threaded rod 10 is threadedly connected to the top of the connecting block 12. The bottom of the connecting block 12 has a clamp 14. By setting the clamp 14, the clamp 14 is placed on both sides of the pipe. Rotating the hexagonal groove 11 causes the threaded rod 10 to rotate, which in turn causes the connecting block 12 to drive the sliding block 9 and the fixing plate 13 to move along the sliding groove 3 towards the middle of the fixing seat 1. This causes the clamp 14 to clamp the two sides of the pipe, thereby fixing the fixing seat 1 and the sensor body 7 on the pipe and preventing the sensor body 7 from falling off.

[0019] The two sliding grooves 3 are symmetrically arranged with the center of the ejector groove 2 as the center of symmetry. The bottom of the connecting block 12 is fixedly installed with a fixing plate 13, and the gripper 14 is fixedly installed with the two sides of the bottom of the fixing plate 13.

[0020] The top of the fixing plate 13 slides in contact with the bottom of the fixing base 1. One end of the top of the fixing plate 13 is fixedly installed with the connecting block 12. The other end of the top of the fixing plate 13 is provided with a connecting groove 15, which slides in contact with the bottom of another connecting block 12.

[0021] A fixing slot 18 is provided on one side of the fixing base 1. A gas detector 19 is fixedly installed on one side of the fixing base 1 through the fixing slot 18. A sensor group 20 located behind the gas detector 19 is fixedly installed on one side of the fixing base 1.

[0022] Sensor group 20 includes a temperature sensor and a vibration sensor.

[0023] The connecting block 12 is L-shaped and placed horizontally. The threaded rod 10 and the part of the connecting block 12 that is higher than the sliding block 9 are connected by a through thread.

[0024] The inner wall of the ejector groove 2 is provided with a limiting slide groove 16. The two sides of the movable plate 5 are integrally connected with limiting sliders 17. The limiting sliders 17 are slidably connected to the inside of the limiting slide groove 16. The bottom of the clamping spring 4 is clamped to the top of the movable plate 5. By setting the ejector groove 2, when the gripper 14 clamps the pipe, the movable plate 5 pushes the connecting rod 6 down under the action of the clamping spring 4, which clamps the sensor body 7 to the outer wall of the pipe, ensuring that the fiber optic sensor is firmly fixed and preventing the fiber optic sensor from falling off the outer wall of the pipe.

[0025] Working principle: Place the clamps 14 on both sides of the pipe, rotate the hexagonal groove 11 to rotate the threaded rod 10, which in turn causes the connecting block 12 to drive the sliding block 9 and the fixing plate 13 to move along the sliding groove 3 towards the center of the fixing seat 1, thereby clamping the clamps 14 with both sides of the pipe, thus fixing the fixing seat 1 and the sensor body 7 on the pipe and preventing the sensor body 7 from falling off. After the clamps 14 are clamped with the pipe, under the action of the clamping spring 4, the movable plate 5 pushes the connecting rod 6 down to press the sensor body 7 against the outer wall of the pipe, ensuring that the fiber optic sensor is firmly fixed and preventing the fiber optic sensor from falling off the outer wall of the pipe.
