Abstract

The invention relates to a ventilation monitoring device used in coal mine safety production, which includes a bearing plate, which includes a ventilation pipe body, a detection power supply, an alarm, and is connected to the detection power supply and the alarm through low-voltage wires to form a low-voltage circuit. No. 1 detection device and No. 2 detection component for detecting wind speed and detecting ventilation failure. The invention is simple in structure, easy to operate and maintain, and has strong pertinence. Through the No. 1 low-voltage circuit used to detect the low wind speed and the No. 2 low-voltage circuit used to detect the fault of the fan, when the wind speed is too low and the fan fails In the event of an emergency, two different alarm sounds are issued to facilitate the maintenance personnel to quickly find the problem and solve the problem quickly, which greatly improves the monitoring performance of the underground ventilation system, and enhances the personal safety of the operators and guarantees Coal mine safety production.

Description

technical field [0001] The invention relates to the technical field of coal mine safety equipment, in particular to a ventilation monitoring device used in coal mine safety production. Background technique [0002] Coal mine ventilation is one of the main technical means to ensure safe production in coal mines. It can dilute harmful gases such as carbon monoxide, carbon dioxide, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, and methane in the mine, as well as supply enough fresh air underground. Climate, creating a good working environment is of great significance. The ventilator is an important facility in the coal mine ventilation system. If it is affected by various external environmental factors during the ventilation process and causes equipment failure, the ventilator cannot ventilate normally or the wind speed is too low, it will easily lead to the harmful gas in the coal mine. Timely discharge will pose a threat to the lives of underground personnel and affect...
