Description

Technical Field

[0001] This utility model relates to the field of natural gas leak detection technology, specifically a natural gas pipeline leak location and detection device. Background Technology

[0002] Natural gas, as a clean energy source, has been widely used in industrial production and residential life, and is mainly transported through long-distance buried or overhead pipelines. However, during long-term operation, pipelines are prone to leaks due to factors such as soil corrosion, damage from third-party construction, pipeline aging, and geological subsidence. This not only causes a large amount of natural gas waste and economic losses, but may also lead to safety accidents such as explosions and poisoning, posing a serious threat to the surrounding environment and the safety of people's lives. Therefore, it is crucial to quickly and accurately locate and detect leaks in natural gas pipelines.

[0003] Existing technologies mostly use laser natural gas detectors to locate and detect leaks in natural gas pipelines. During detection, users often handhold the detector, which is time-consuming and labor-intensive. Alternatively, the detector can be mounted on a mobile device for auxiliary detection, but these devices are typically fixed to the mobile equipment, requiring adjustment of the detection angle. This is inconvenient, results in a limited detection range, and affects the overall detection efficiency of natural gas pipelines. Therefore, we propose a natural gas pipeline leak location and detection device to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-4 As shown, this utility model provides a natural gas pipeline leak location and detection device, including a mounting base 1, a first L-shaped frame 2 integrally formed at the bottom end of the mounting base 1, a second L-shaped frame 3 at the bottom end of the first L-shaped frame 2, a mounting bottom frame 4 at the bottom inner side of the second L-shaped frame 3, a mounting top frame 41 at the top end of the mounting bottom frame 4, a laser natural gas detector 5 installed between the mounting bottom frame 4 and the mounting top frame 41, a fixing bolt 42 threaded between the mounting bottom frame 4 and the mounting top frame 41, and mounting crossbars 6 at the four corners of the mounting base 1; A rotating horizontal shaft 7 is fixedly installed on the side end of the mounting base frame 4. A rotating bearing 71 is fixedly fastened to the bottom of the second L-shaped frame 3. The middle part of the rotating horizontal shaft 7 is fixedly fastened to the middle part of the rotating bearing 71. A first gear 72 is fixedly installed at the end of the rotating horizontal shaft 7. A second gear 73 is meshed with the bottom of the first gear 72. A drive shaft 74 is fixedly installed in the middle of the second gear 73. The drive shaft 74 is rotatably mounted on the bottom of the second L-shaped frame 3 through a bearing. A worm gear 75 is fixedly installed at the end of the drive shaft 74. A worm 76 is meshed with the top of the worm gear 75. The worm gear 76 is rotatably mounted on the outside of the second L-shaped frame 3; a drive motor 77 is fixedly mounted on the outer wall of the second L-shaped frame 3 near the worm gear 76. The drive end of the drive motor 77 and the shaft end of the worm gear 76 are fixedly mounted. By turning on the drive motor 77 at the position of the mounting base frame 4, the worm gear 76 is driven to rotate, thereby controlling the second gear 73 to drive the first gear 72 to rotate, which in turn controls the rotation of the horizontal axis 7 to drive the mounting base frame 4 to rotate, thereby controlling the laser natural gas detector 5 to perform X-axis rotation adjustment.

[0022] A protective cover 8 is fixedly installed on the outer wall of the second L-shaped frame 3 near the drive motor 77. The first gear 72, the second gear 73, the worm gear 75, the worm 76 and the drive motor 77 are located in the protective cover 8.

[0023] The connection method between the second L-shaped frame 3 and the first L-shaped frame 2 is the same as the connection method between the mounting base frame 4 and the second L-shaped frame 3. The rotating horizontal axis 7 at the position of the mounting base frame 4 and the rotating horizontal axis 7 at the top position of the second L-shaped frame 3 are vertically distributed, which facilitates the control of the laser natural gas detector 5 to perform Z-axis rotation adjustment.

[0024] A connecting screw 61 is vertically installed at one end of the mounting frame 6. Connecting slots are provided at the four corners of the mounting base 1. The connecting screw 61 moves through the corresponding connecting slot. A connecting nut 62 is threaded onto the end of the connecting screw 61. By setting the connecting screw 61, the mounting frame 6 is fixed by the connecting screw 61 and the connecting nut 62. The mounting crossbeam 6 has a mounting groove 601 at the end away from the connecting screw 61. By setting the mounting groove 601, it is convenient to use bolts to fix the mounting crossbeam 6 to an external, movable device.

[0025] Working principle: This positioning and detection device can be suspended and fixed. The entire positioning and detection device is fixed to the external drone aircraft with bolts through the mounting frame 6. The mounting frame 6 of appropriate length is selected according to the installation distance. When the external drone aircraft flies, it can drive the entire positioning and detection device to fly and move, thus making it convenient to locate and detect leaks in large areas of natural gas pipelines in complex terrain. The positioning detection device can also be installed in a placement manner. The entire positioning detection device is fixed to an external, self-moving device with bolts using the mounting frame 6. Depending on the installation distance, a suitable length of mounting frame 6 is selected, and the external, self-moving device is used to move the entire positioning detection device. During the specific detection, the laser natural gas detector 5 is used to locate and detect the leak point of the natural gas transmission pipeline. Specifically, by activating the drive motor 77 at the mounting base frame 4, the worm gear 76 is driven to rotate the worm wheel 75 and the drive shaft 74, thereby controlling the second gear 73 to drive the first gear 72 to rotate, which in turn controls the rotation of the horizontal axis 7 to rotate the mounting base frame 4, thereby controlling the laser natural gas detector 5 to perform X-axis rotation adjustment. Furthermore, by activating the drive motor 77 at the first L-shaped frame 2 position, the laser natural gas detector 5 is controlled to rotate and adjust along the Z-axis, thereby flexibly adjusting the angle of the laser natural gas detector 5. This makes it easy to use, increases the detection range, facilitates subsequent rapid maintenance, and increases the overall detection efficiency of the natural gas transmission pipeline.
