Description

Technical Field

[0001] This utility model relates to the technical field of natural gas detection devices, and in particular to a natural gas pipeline leak detection device. Background Technology

[0002] Natural gas is a fossil fuel mainly composed of methane. It is formed by the decomposition of underground organic matter under high temperature and pressure conditions over millions of years. Natural gas is usually found in oil fields, coal seams, and natural gas fields, often coexisting with oil. Natural gas is commonly used in heating systems for residential and commercial buildings.

[0003] When natural gas is transported through pipelines, it is usually necessary to use natural gas detection devices to inspect the pipeline surface to monitor and detect natural gas leaks. These devices are widely used in residential, industrial, and commercial environments to ensure safety and prevent accidents such as fires and explosions. However, most existing natural gas detection devices are usually installed on the surface of the natural gas pipeline. After installation, it is usually inconvenient to adjust their position, which reduces their effectiveness. Moreover, adjusting the position of the natural gas detection device can easily cause the natural gas pipeline to shake, leading to a risk of pipeline leakage. Therefore, it is necessary to solve these problems. Utility Model Content

A rotating mechanism for rotating the two second conveying rollers 4 is provided inside the second fixing block 11. Through the two first conveying rollers 3 and two second conveying rollers 4 located inside the first fixing block 1 and the second fixing block 11, the device can be easily adjusted on the natural gas pipeline after installation, thereby improving the device's effectiveness and preventing shaking of the natural gas pipeline during adjustment.

[0019] Reference Figure 1 and Figure 3In a preferred embodiment, the connecting mechanism includes connecting blocks 13. Two slots 12 are formed at both ends of the first fixing block 1 and the two second fixing blocks 11, with each pair of slots 12 corresponding to each other. Four connecting blocks 13 are provided, each disposed inside one of the two slots 12. Two first fixing screws 14 are installed inside each of the four connecting blocks 13, and these screws cooperate with the first fixing block 1 and the second fixing block 11 respectively. Four second fixing screws 15 are installed at the bottom of the second fixing block 11, and these screws 15 are inserted into the second fixing block 11 and cooperate with the first fixing block 1 to fix the first fixing block 1 and the second fixing block 11, thereby facilitating the installation of the device.

[0020] Reference Figure 2 and Figure 4 In a preferred embodiment, the first fixing block 1 and the second fixing block 11 are horizontally provided with through holes 16 on opposite sides. The first fixing block 1 and the second fixing block 11 are provided with connecting grooves 17 at both ends. The connecting grooves 17 are disposed inside the two through holes 16. The two connecting blocks 13 are rotatably connected to the inside of two of the connecting grooves 17. The center of the inside of the two first conveying rollers 3 is sleeved with a rotating shaft 31. The two ends of the two rotating shafts 31 are rotatably sleeved inside the first fixing block 1. The two second conveying rollers 4 are rotatably connected to the inside of the other two connecting grooves 17 to restrict the rotation of the two first conveying rollers 3, thereby facilitating the movement of the device.

[0021] Reference Figure 1 and Figure 4 In a preferred embodiment, the rotating mechanism includes two worm gears 41, which are rotatably fitted inside two other connecting grooves 17. The two worm gears 41 are fixedly connected to the center of the surfaces of the two second conveying rollers 4. A second rotating shaft 51 is rotatably connected inside the second fixing block 11.
