Abstract

The invention relates to an alarm device, in particular to a gas leakage monitoring alarm device for coal mine operation. The invention provides the gas leakage monitoring and alarming device for the coal mine operation, which improves the detection speed, further ensures the personal safety and realizes data display. A gas leakage monitoring alarm device for coal mine operation comprises a base, a first connecting rod is arranged on the front side of the lower portion of the base, and a sealing door is hinged to the first connecting rod; the handle is arranged at the bottom of the front side of the sealing door; the limiting column is arranged at the bottom of the front side of the base; the gas parameter disc is arranged on the front side of the middle of the base; the test probe for detecting high-concentration gas is connected between the inner sides of the upper part of the base; and the buzzer is arranged at the top of the base. The tester can intermittently detect the gas concentration in the air, and the detected data is specifically displayed on the gas parameter disc to cooperate with the work of workers in a coal mine.

Description

technical field [0001] The invention relates to an alarm device, in particular to a gas leakage monitoring and alarm device used in coal mine operations. Background technique [0002] In 2006, the State Bureau of Coal Mine Safety Supervision published on the Internet the draft for comments on the butterfly mine safety monitoring system and the AQ standard for gas alarm lights, which stipulated that "mining workers, drilling workers, and workers in the return air flow should use gas alarms" In other words, to prevent personal safety hazards caused by excessive gas concentration in the air of coal mines, it is necessary to detect the gas concentration, and when the detection exceeds the standard, an alarm will be issued to alert the staff to take emergency measures quickly. [0003] However, the existing gas warning lights cannot quickly detect and feedback the gas concentration, and the air circulation speed in the coal mine is limited, which leads to insufficient detection s...
