Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and in particular relates to a protective device for a sensor. Background Art

[0002] A sensor is a sensor device that detects one or more substances such as gas or liquid, including methane sensors, temperature sensors, humidity sensors, etc. Methane sensors are widely used in coal mine safety monitoring systems. They are fixed on the walls of mining working faces, goafs, return air tunnels, electromechanical chambers, etc. to continuously monitor the methane concentration. When the methane concentration exceeds the limit, it can automatically send out sound and light alarms, and the operators will evacuate quickly after hearing them to avoid methane poisoning.

[0003] Currently, some methane sensors on the market are used in coal mining, but these methane sensors can only be carried by workers when on the move. Since methane is lighter than air, the sensors cannot accurately measure the methane concentration while on the move, which affects the workers' judgment of the methane concentration and causes irreparable losses. Some portable sensors on the market take the portability into consideration and do not have corresponding protective facilities on the surface. Ordinary impacts during operation can easily cause damage to the methane sensors, affecting construction efficiency. Utility Model Content
