Coal mine underground movable type gas drainage equipment

Abstract

The invention provides coal mine underground movable gas drainage equipment. The gas drainage equipment comprises a movable base, movable brake wheels, storage grooves, extraction equipment, connecting pipes, a first guide pipe, a rotatable fixing and sealing fixed-point air suction cover structure, a detachable automatic conveying pipe structure, a supportable pressing and covering protection frame structure, rotatable supporting and fixing rod structures, a suction ventilator, supporting plates, a control box, a PLC, a power switch and a display screen, the movable brake wheels are connected to the four corners of the lower end of the movable base through bolts correspondingly, and the storage grooves are formed in the four corners of the movable base correspondingly. According to the gas drainage equipment, through the arrangement of a metal hose, an air suction cover, a positioning pipe, a first fixing plate and a sleeving hole, the air suction cover can be driven to rotate by rotating the metal hose in the using process, the air suction cover is fixed to the inner wall of a mine through the first fixing plate, then the air suction cover corresponds to a proper position, and positioning extraction work can be conveniently carried out in the gas extraction process.

Description

technical field [0001] The invention belongs to the technical field of coal mine equipment, in particular to a mobile underground gas drainage equipment for coal mines. Background technique [0002] Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of ancient plants accumulating into coal. In a high-temperature, high-pressure environment, while coal is formed, due to physical and chemical effects, gas continues to be generated. It is a colorless, odorless gas, but sometimes you can smell an apple-like aroma. This is due to the simultaneous gushing of aromatic hydrocarbon gas and gas. The relative density of gas to air is 0.554. The density is 0.716kg / m3, and the permeability of gas is 1.6 times that of air. It is difficult to dissolve in water, does not support combustion and cannot maintain breathing. When it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and can burn or ex...
