Coal mine safety disaster-resistant type automatic main drainage system

The invention relates to a mine safety automatic water discharge system, which can realize the normal discharge of mine and recover the water discharge after disaster. The inventive system is formed by a full-automatic ground remote detecting controlling system, a multistage eccentric water pump, and a water-cooling/separating wind-cooling waterproof explosion-proof motor. The full-automatic ground remote detecting controlling system can real time remotely detect the water level and the device condition, to realize remote stopping and starting the machine, and the switch of electric valve of discharge network of under-well main pump, while it is formed by a control switch, a sensor, a data line, data display and process hardware and relative software. The water pump is a general multistage eccentric discharge pump, driven by the motor. The motor is a water-cooling or separating wind-cooling waterproof explosion-proof motor with automatic control.
