Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a gas detection instrument placement box with a positioning function. Background Art

[0002] Photoacoustic spectroscopy is a trace gas detection technology with high sensitivity, high selectivity and large dynamic monitoring range. It is mainly used in biology, medicine, materials science, chemistry, material surface research, pop research and atmospheric environment monitoring. Photoacoustic spectroscopy can effectively convert light signals into sound signals, and calculate the final concentration of the gas through the detection of sound signals by a microphone. Due to the special optical structure and signal acquisition of photoacoustic spectroscopy technology, and the special calculation process in the signal processing process, this method can efficiently collect weak photoacoustic signals and effectively eliminate the interference of background signals. Therefore, it is very suitable for the measurement of trace gases and interference-free measurement in complex environments.

[0003] In recent years, with the development of lasers, microphones, photoacoustic cells, and weak signal detection technology, as well as the combination of computer control and data processing technology with photoacoustic spectrometers, the existing trace-level photoacoustic spectroscopic multi-gas analyzers are mostly integrated into an integrated box-shaped structure for easy carrying and detection at any time. However, due to the complex internal structure of the photoacoustic spectroscopic gas detector, which contains many optical equipment components, it is necessary to avoid collision when moving the gas detector to avoid affecting the detection effect and accuracy. The existing gas detector does not have good shock absorption measures, which can easily cause it to contact with the placement box and cause bumps and damage. Therefore, it is necessary to design and modify the placement box of the gas detection instrument to solve the problem of damage caused by collision between the detection instrument and the placement box.
