Description

Technical Field

[0001] The present application relates to the technical field of gas detection equipment, and in particular to a portable hazardous gas detector. Background Art

[0002] On-site coal mine safety measures are a complex and multifaceted system, covering multiple aspects from equipment configuration to personnel training, aiming to ensure the safety of miners' lives and the efficient operation of mines. Gas detectors play a vital role in coal mine safety measures. They work based on sensor technology and can monitor the concentration of toxic and harmful gases underground in real time. When the concentration exceeds the safe range, the gas detector will promptly issue an alarm to remind miners to evacuate dangerous areas, thereby ensuring the safety of miners.

[0003] Since the gas detector needs to monitor the concentration of toxic and harmful gases underground in real time, when the gas detector is used in the humid environment underground, its internal electronic components and line connection ports are susceptible to moisture and short circuit, which leads to its insufficient safety. Therefore, improvements are now made to a portable hazardous gas detector. Utility Model Content

[0006] By adopting the above technical solution, the positioning plate is limited and fixed inside the mounting frame through the fixing unit, so that the moisture-proof plate is clamped between the positioning plate and the mounting frame for installation and fixation. By providing the moisture-proof plate, the moisture-proof performance of the detection equipment body is improved, and the electronic components and line connection ports inside the detection equipment body are prevented from short-circuiting due to moisture, thereby ensuring that the gas detector can be used normally in such a humid environment underground.

[0009] As a preferred technical solution of the present application, a limiting hole is provided inside the positioning plate, the other end of the fixing rod is slidably inserted into the limiting hole, and the fixing rod is adapted to the limiting hole.

[0010] By adopting the above technical solution, when the moisture-proof board needs to be replaced, the fixing rod is pulled out from the inside of the limiting hole by pulling the moving block. At this time, the positioning plate can be rotated to take out the old moisture-proof board and replace it with a new moisture-proof board, and then the positioning plate can be rotated to clamp the new moisture-proof board between the positioning plate and the mounting frame. The moving block is released and under the action of the spring, the fixing rod is reinserted into the inside of the limiting hole to limit and fix the positioning frame.
