Abstract

The invention relates to an automatic monitoring device for a mining explosion door, and mainly solves the technical problems that the conventional mining explosion door is heavy and cannot be accurately reset after being passively opened and deformed, and the like. The technical scheme is that: the automatic monitoring device for the mining explosion door comprises at least one monitoring host, photographic equipment, a video processor, an air shaft explosion door, a programmable logic controller (PLC) control cabinet, a server, an air velocity sensor, a carbon monoxide sensor, a smoke sensor, a gas sensor, a temperature sensor, a positive pressure sensor, a negative pressure sensor and a switch, wherein the output end of the photographic equipment is connected with the input end of the video processor; the output end of the video processor is connected with the input end of the monitoring host; the output ends of the air velocity sensor, the carbon monoxide sensor, the smoke sensor,the gas sensor, the temperature sensor, the positive pressure sensor and the negative pressure sensor are connected with the input end of the PLC control cabinet; and the input end of an air shaft explosion door control device is connected with the output end of the PLC control cabinet.

Description

technical field [0001] The invention relates to an automatic monitoring device for a mine explosion-proof door, which belongs to an explosion-proof automatic monitoring device for a sealing device on the return air wellhead of a mine ventilator. Background technique [0002] The explosion-proof door is a special sealing device installed on the return air wellhead where the main fan is installed. During normal ventilation, it is used to isolate the downhole airflow from the ground atmosphere to prevent short-circuit of the airflow and ensure the normal ventilation system. Because the current explosion-proof doors only have a simple explosion-proof function, there are technical defects such as heavy weight, difficult to open manually, and passive opening deformation that cannot be correctly reset. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide an automatic monitoring device for mine explosion-proo...
