Abstract
The utility model discloses an air-reversing fire protection device for a mine belt transportation lane. The air-reversing fire protection device is characterized in that an air channel lane is arranged on the upper portion of the position between the belt transportation lane and a main mine air return lane, and a cross heading is arranged on the lower portion of the position between the belt transportation lane and the main mine air return lane; an air channel lane air door is arranged in the air channel lane; a cross heading air door and a safety monitoring device are arranged in the cross heading; a smoke transducer and an audible-visual alarm are arranged in the belt transportation lane; the air channel lane air door, the cross heading air door, the smoke transducer and the audile-visual alarm are connected with the safety monitoring device through wires. When fires occur in the belt transportation lane, the smoke transducer transmits signals to the safety monitoring device, the safety monitoring device sends out the signals to make the air door in the cross heading be opened and the air door in the air channel lane be closed, and reverse air is generated in the belt transportation lane below the cross heading, the air current of the belt transportation lane is made to be shorted, and therefore harmful gas directly enters the main mine air return lane and is prevented from entering a working face.
Description
Technical field
The utility model relates to a kind of inverted ventilation firebreak device, especially a kind of inverted ventilation fire protection device for mine belt transportation lane.
Background technology
The inverted ventilation firebreak device plays very important effect in mine production, it is not only for the putting out of flare, and prevents that a large amount of poison gas from spreading on work plane and all play great role, so the inverted ventilation firebreak device is not lack in mine production.And during existing mine produces, especially in the belt-conveying lane, because belt and fixture easily cause spark because rubbing, and cause fire, also there is no a set of energy inverted ventilation firebreak device, not only putting out of fire played to great role, and can prevent that toxic gas from spreading in mine.
The utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of inverted ventilation fire protection device for mine belt transportation lane.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of inverted ventilation fire protection device for mine belt transportation lane, and it is that top between belt-conveying lane and mine main return airway is provided with Xiang, bottom, air channel and is provided with connection roadway; In the lane, air channel, be provided with lane, air channel air door, in connection roadway, be provided with connection roadway air door and safety monitoring device, in the belt-conveying lane, be provided with Smoke Sensor and audible-visual annunciator; Lane, air channel air door, connection roadway air door, Smoke Sensor and audible-visual annunciator connect with safety monitoring device by wire.
The beneficial effects of the utility model are:
When the condition of a fire appears in the belt-conveying lane, Smoke Sensor is transferred to signal in safety monitoring device, safety monitoring device sends signal closes the door opening in connection roadway, the air door in the lane, air channel, make the belt-conveying lane below connection roadway produce reverse wind, make belt-conveying lane Air escape branch, make pernicious gas directly enter into mine main return lane, avoided entering into work plane.
The accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Marginal data, 1, the mine main return airway; 2, connection roadway; 3, connection roadway air door; 4, safety monitoring device; 5, belt-conveying lane; 6, Smoke Sensor; 7, audible-visual annunciator, 8, the lane, air channel, 9, lane, air channel air door.
The specific embodiment
Fig. 1 is an embodiment of the present utility model, inverted ventilation fire protection device for mine belt transportation lane as shown in the figure, and it is that top between belt-conveying lane 5 and mine main return airway 1 is provided with lane, air channel 8, bottom is provided with connection roadway 2; In lane, air channel 8, be provided with lane, air channel air door 9, in connection roadway 2, be provided with connection roadway air door 3 and safety monitoring device 4, in belt-conveying lane 5, be provided with Smoke Sensor 6 and audible-visual annunciator 7; Lane, air channel air door 9 connection roadway air doors 3, Smoke Sensor 6 and audible-visual annunciator 7 connect with safety monitoring device 4 by wire.
