Ventilation monitoring system for gas explosion prevention

Abstract

The invention discloses a ventilation monitoring system for gas explosion prevention. The system comprises a plurality of gas concentration detection devices, a host monitoring machine and an automatic ventilation device which is controlled by the host monitoring machine; the automatic ventilation device comprises a travelling chassis, an electric travelling drive mechanism, and ventilation equipment and an electronic circuit board which are installed on the travelling chassis, wherein the ventilation equipment comprises an electric ventilator, a pipeline reeling and releasing device on which a ventilation hose is continuously wound from inside to outside, and an electric pipeline reeling and releasing drive mechanism which drives the pipeline reeling and releasing device; and a controller, a global position system (GPS) positioning unit, an obstacle detection unit, a travelling direction detection unit, an air output detection unit and a wireless communication module 1 are arranged on the electric circuit board. The system has the advantages of simplicity in structure, reasonability in design, convenience in operation, high intelligent degree and good use effect, and can be used for solving problems of heavy field workload, more labor and material input, inconvenience in use and operation, poorer ventilation effect and the like of the existing underground coal mine ventilation devices.

Description

technical field [0001] The invention relates to a ventilation monitoring system, in particular to a ventilation monitoring system for gas explosion prevention. Background technique [0002] In recent years, my country's coal mine safety accidents have occurred frequently, causing heavy casualties and huge economic losses. The safety production of coal mines has attracted the attention of all walks of life, and gas explosion is an important aspect of coal mine safety accidents. In essence, a gas explosion is a violent oxidation reaction between a certain concentration of methane and oxygen in the air at a certain temperature. The conditions for a gas explosion are a certain concentration of gas, the existence of a high-temperature fire source, and sufficient oxygen. [0003] In the actual production process, it is necessary to take many measures to prevent gas ignition, such as prohibiting the use of naked flames within 20m around the wellhead room, gas drainage station and m...
