Description

Technical Field

[0001] The utility model relates to the technical field of gas leakage monitoring, in particular to an infrared spectrum imaging telemetry system for infrared detection of gas leakage. Background Art

[0002] In the process of industrial production, pipelines that circulate harmful or flammable and explosive gases need to be monitored in real time to avoid gas leaks that affect industrial production and the safety of workers.

[0003] Most of the existing gas optical detection methods use infrared spectral imaging technology for remote sensing. Infrared spectral imaging technology has the advantages of fast response speed and wide range of gas detection. In industrial parks with a wide distribution range of pipelines, it is necessary to install multiple infrared spectral imaging devices to monitor gas leakage, and cooperate with computers for processing detection data to form an infrared spectral imaging telemetry system that uses infrared to detect gas leakage. When the infrared spectral imaging device is installed at a high place, it is mostly fixed with screws, and multiple screws need to be screwed. Infrared spectral imaging easily blocks the sight of the installer, and it is not convenient to assemble multiple screws at different positions on the base of the equipment, resulting in a cumbersome installation process during the installation of multiple infrared thermal imaging devices. For this reason, there is an improved technology on the market that proposes an online hydrogen cyanide leakage infrared telemetry device, including an online telemetry unit set in an open factory area, the online telemetry unit includes an infrared thermal imaging module and a Fourier transform infrared spectrum module, and a docking seat is set at the bottom of the online telemetry unit, and a positioning component on the docking seat. The improved technology only needs to be installed and positioned at one point on the surface of the docking seat on the equipment, without the need to tighten multiple bolts for fixing, reducing the inconvenience caused by equipment obstruction during the installation process, while ensuring the stability of the equipment and simplifying the installation steps. By removing the positioning unit, the position of the equipment can be moved to complete the disassembly work;

[0004] However, when the above-mentioned improved technology is installed, it is only fixed at one installation position, the fixing structure is not firm, and its installation part is not protected, which is not conducive to long-term outdoor use. Therefore, it is necessary to further improve the structure of the infrared spectrum imaging telemetry system for infrared detection of gas leaks. Utility Model Content
