Split full-automatic disaster prevention device of coal mine

Abstract

The invention provides a split full-automatic disaster prevention device of a coal mine; the device mainly comprises a ground control device, a sensor control device, a grating door, a prevention door, a gutter hydraulic gate, a shutter device, an electro-hydraulic integrated cabinet, a grating and a prevention door auxiliary door frame. The split full-automatic disaster prevention device of the coal mine is arranged in one way or symmetrically in two ways below the coal mine. According to the split full-automatic disaster prevention device of the coal mine, the grating door can be closed before the whole device is turned off safely, so that impurities in water are intercepted, and the influence of impact wave produced in various explosion and the carried impurities on the closing of the prevention door and destructive impact are mitigated. Particularly the devices which are close to a door hinge and other structures are difficult to turn on or off when the use space of a narrower roadway, a chamber and the like is restricted, and the device can meet the requirement to intelligently, quickly and comprehensively block and prevent various disasters in one way or two ways. The grating door and the prevention door are provided with rescue doors.

Description

technical field [0001] The invention relates to a mine disaster blocking and preventing device, in particular to a split mine fully automatic disaster blocking and preventing device. Background technique [0002] At present, when disasters occur in mines involving fire, water, explosion, harmful gas, high-density coal dust, etc., it has not been found that the use of fully automatic energy to comprehensively block fire prevention, water, explosion, harmful gas, etc. High-density coal dust and devices to prevent, reduce or eliminate disasters and losses, especially in the case of narrow roadways, caverns, etc., where the use of space is limited, it cannot effectively clean the underground roadways, caverns, etc. And through disasters such as water inrush, water gushing, harmful gas exceeding the standard, high-density coal dust accumulation, gas and coal dust explosions, etc., intelligent, rapid, comprehensive blockage and prevention are realized. Serious accidents often occu...
