Abstract
The utility model provides an underground movable gas drainage pump for a coal mine, and the underground movable gas drainage pump can be used for overcoming the problems of an existing gas drainage pump that the use noises are great, the movement is inconvenient, the existing gas drainage pump cannot be automatically controlled to be opened and closed, the wind power is not enough and the like. The underground movable gas drainage pump for the coal mine provided by the utility model comprises a shell, wherein a wind collection pipe is connected with the front end of the shell; a motor is mounted in the middle of the shell; the underground movable gas drainage pump is characterized in that the motor is connected with a fan shaft by a reversing driving device; impeller assemblies are mounted on the two sides of the fan shaft respectively; the shell is provided with a gas sensor; the gas sensor is connected with the motor by a controller. The underground movable gas drainage pump for the coal mine provided by the utility model is used for discharging gas under the coal mine.
Description
Technical field:
The utility model relates to ventilation equipment under a kind of coal mine, is specifically related to the portable gas suction pump of a kind of underground mine use.
Background technology:
Usually need gas suction pump is installed under the coal mine that the pernicious gases such as methane, carbon monoxide are arranged, at the diffuser port of export, a flexible conduit is housed, do exhaust, with ventilation fan, support the use, effectively upgrade mine gas.Prevent the blast that exceeds standard and cause because of methane, guarantee personnel in the pit's safety.Gas suction pump is prevention underground coal and Gas Outburst, basic goal and the measure that gas is administered in colliery, namely only have the extraction by gas pump to be only the root that obtains gas control, what no person was simple is the effect that impossible obtain essence by the wind gas-removing, and the extraction by gas pump is also faster to administer Gas Disaster.
Existing gas suction pump exists and uses noise large, and is mobile inconvenient, can not automatically control unlatching, close, the problems such as wind-force deficiency.
Summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of underground mine use portable gas suction pump, facilitate the timely firedamp drainage gas in down-hole, avoid down-hole that Gas Disaster occurs, simultaneously the utility model conveniently moving, can automatically control unlatching, close, wind-force is large.
