Using method of intelligent ventilation device on coal face

Abstract

The invention discloses an intelligent ventilation device on a coal face. The intelligent ventilation device comprises a detection mechanism, a main control mechanism, a frequency conversion mechanism and a pumping and draining mechanism, and the detection mechanism, the main control mechanism, the frequency conversion mechanism and the pumping and draining mechanism are electrically connected in sequence; the detection mechanism comprises a plurality of CO sensors and methane sensors, the main control mechanism comprises a main control box, a main control circuit board and a concentration display screen, the CO sensors and the methane sensors are electrically connected with the main control circuit board, and the concentration display screen is electrically connected with the main control circuit board; the frequency conversion mechanism comprises a frequency conversion box, an auxiliary control circuit board and a transformer, the main control circuit board is electrically connected with the auxiliary control circuit board, and the auxiliary control circuit board is electrically connected with the transformer; and the pumping and draining mechanism comprises an air suction barrel, an exhaust pipeline and an air suction pipe, a variable frequency motor is fixedly connected into the air suction barrel and electrically connected with the auxiliary control circuit board, and fan blades are fixedly connected to the variable frequency motor. The problem that in the prior art, gas explosion is prone to being caused due to the fact that harmful gas is accumulated at the upper corner position can be solved.

Description

technical field [0001] The invention relates to the technical field of coal mining safety, in particular to a method for using an intelligent ventilation device on a coal mining face. Background technique [0002] In the process of coal mining, the upper corner of the working face will not be well ventilated due to the law of wind flow. In addition, the top corner of the upper corner is relatively high, which will cause harmful gases such as CO and methane to accumulate in the upper corner of the goaf over time. It is easy to cause danger such as gas explosion. If these harmful gases can be detected in time and relevant measures are taken to discharge them into the return air alley, the occurrence of gas explosions can be greatly reduced. Contents of the invention [0003] The purpose of the present invention is to provide a method for using an intelligent ventilation device on a coal mining face, so as to solve the problem in the prior art that harmful gases such as CO a...
