Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a gas leakage detection mechanism for chemical production safety. Background Art

[0002] Gas detector is an instrument tool for detecting gas leakage concentration. It is mainly used for leak detection of dangerous gases. It can also detect leaks of compressed gases. The main detection principle is to use an ultrasonic probe to aim at the pipeline and use the high-frequency ultrasonic signal generated by the pipeline leakage to convert the ultrasonic probe into an electrical signal and send it to the host, thereby sounding an alarm.

[0003] When using gas detectors, many detectors are fixedly installed in densely populated areas of pipelines. Multiple gas detectors are installed in sections to accurately detect gas leaks in these pipelines. Once a leak occurs in the pipeline, the alarm light on the gas detector will flash immediately to inform the staff of the leak. Existing gas detectors are installed on pipelines in the form of straps or screws and nuts. Although this installation method can meet the purpose of installation, the installation process is relatively complicated and slow, which is not conducive to the daily operation of the staff. Therefore, a detection mechanism that can easily install the gas detector on the pipeline is needed to solve the above-mentioned problems. Utility Model Content

[0026] In one embodiment of the utility model: the surface of the insertion rod 16 located in the longitudinal groove of the cross groove 15 is fixedly sleeved with a longitudinal plate 17, the surface of the insertion rod 16 located in the longitudinal groove of the cross groove 15 is movably sleeved with a second spring 18, the longitudinal plate 17 is located on the inner side of the second spring 18, and when the second spring 18 is not subjected to external force, the insertion rod 16 is located in the groove 19, and the position of the insertion rod 16 is limited by the longitudinal plate 17 and the second spring 18, so that it can automatically reset after moving.

[0027] In one embodiment of the present invention, the diameters of the longitudinal plate 17 and the second spring 18 are both larger than the diameter of the transverse groove of the cross groove 15 , so that the longitudinal plate 17 and the second spring 18 will never enter the transverse groove of the cross groove 15 .
