Description

Technical Field

[0001] The present application relates to the technical field of coal mine smoke monitoring, and more specifically, to a multi-angle coal mine smoke monitoring and alarm device. Background Art

[0002] Coal mine accidents are often caused by excessively high smoke concentrations in coal mines. Therefore, timely and accurate monitoring of smoke in coal mines is crucial. Usually, multiple designated monitoring areas are selected in the coal mine to install mining-grade coal mine smoke sensors, which can detect and process the smoke concentration generated in the coal mine in real time. When the smoke concentration is too high, an alarm signal will be issued in time to remind the workers to evacuate safely and urgently. The patent application with the existing announcement number CN221442657U proposes a multi-angle coal mine smoke monitoring and alarm device. The device can horizontally rotate the first mounting tube and the second mounting rod to facilitate simultaneous smoke monitoring at multiple angles. The second mounting tube can be longitudinally angularly rotated by the cooperation of the connecting seat and the connecting screw. The degree of adjustment is wider, the adjustment range is wider, and the protective net that is easy to disassemble can prevent debris and other foreign objects from entering its interior, and can protect the smoke sensor body. At the same time, the air inlet tubes at both ends of the first mounting tube have a good sound amplification effect, which is more convenient for sound transmission and safer and more reliable. In view of the above-mentioned related technologies, the utility model author believes that the following defects still exist: the smoke monitoring alarm device in the reference needs to adjust the direction angle one by one during installation, which is inconvenient to adjust, and no matter which monitoring direction has smoke concentration exceeding the standard, an alarm operation will be issued, and it is impossible to intuitively determine which side of the smoke concentration exceeds the standard, and it is impossible to determine the escape direction in a timely and accurate manner, which easily causes the escape direction to be wrong. In view of this, we propose a multi-angle coal mine smoke monitoring alarm device. Utility Model Content
