Description

Technical Field

[0001] The utility model belongs to the field of hydrogen monitoring, and particularly relates to a hydrogen leakage monitoring and alarming device. Background Art

[0002] A hydrogen leakage monitoring and alarming device is a device used to monitor hydrogen leakage and issue an alarm. This kind of device is very important in many industrial and laboratory environments to ensure safety. Hydrogen sensors usually adopt electrochemical, semiconductor, catalytic combustion or infrared technologies, and each technology has its own advantages and disadvantages.

[0003] When the existing hydrogen leakage monitoring and alarming devices are in use, most of them use electrochemical sensors to monitor the hydrogen concentration in the air. Although the electrochemical sensors have high sensitivity to hydrogen, their failure rate is also relatively high after long-term use. Moreover, once a failure occurs, it is difficult for workers to know the cause of the failure, which affects the workers' rapid maintenance of the device. In addition, general hydrogen leakage monitoring and alarming devices are often powered by an external power supply. However, in the event of a sudden power outage, the external power supply stops supplying power, and the monitoring device will lose its working ability, thus posing a great hidden danger to the safety of workers during the power outage time.

[0004] Therefore, aiming at the problems that the electrochemical sensor in the hydrogen leakage monitoring and alarming device is not only prone to failure but also not easy to maintain during use, and the power supply system is difficult to ensure the normal operation of the device in the event of a sudden power outage, a hydrogen leakage monitoring and alarming device is developed. By adding a self-monitoring structure, a backup power supply structure, a double-layer protection and a dust-proof structure to the hydrogen monitoring device, the use effect of the device in the face of power outage during use can be greatly improved, the occurrence probability of its failure and the maintenance difficulty can be reduced, and its service life during use can also be improved. Summary of the Utility Model

Limit buckles are fixedly connected to the four corners of the inner wall of the outer shell, and an inner shell is arranged on the inner wall of the outer shell.
