Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal mine tunneling, especially to an alarm device for coal mine tunneling. BACKGROUND

[0002] Coal mine underground harmful gas monitoring and early warning refers to monitoring harmful gases in the air underground and giving early warning through alarm to protect the safety of miners. There are various harmful gases in the coal mine, such as methane, carbon monoxide, hydrogen sulfide, etc. If the concentration of these gases exceeds a certain level, it will threaten the health of miners and even cause accidents such as explosion and poisoning. The traditional method of monitoring harmful gases underground mainly relies on miners holding portable gas detectors for detection, but this method has problems such as insufficient manpower, low detection accuracy, and high time cost.

[0003] The patent application with the publication number CN222633281U proposed in the prior art fixes the installation bracket on the inner wall of the coal mine shaft through the L-shaped mounting plate and bolts. When a person enters the coal mine, the person pushes the L-shaped push rod, and the gas monitoring box slides on the installation bracket under the drive of the U-shaped seat and the moving roller, so as to facilitate the movement of the gas monitoring box in the coal mine. When the gas monitoring box moves, the gas in the coal mine enters the gas monitoring box through the gas flow hole. The multiple gas monitoring sensors are arranged to facilitate the monitoring of different harmful gases in the coal mine. When the harmful gas exceeds the set value, the gas monitoring sensor feeds back the voltage signal to the audible and visual alarm and the control panel. The audible and visual alarm sends an alarm after receiving the signal to remind the surrounding personnel to stop advancing and evacuate in time. The control panel displays the data on the display screen for the personnel to observe the harmful gas over-standard value. The device has a simple structure and is convenient to operate. It can be fixed at a specified position in the coal mine to monitor and early warn harmful gases. At the same time, it is also convenient for personnel to carry and move it in the coal mine to monitor and early warn harmful gases, improving the convenience of monitoring harmful gases in the coal mine.

[0004] However, the current alarm device is installed on the inner wall of the coal mine through a sliding rail.
