Abstract
The invention discloses a compressed air curtain device of a coal mine underground emergency system. The compressed air curtain device of the coal mine underground emergency system comprises a rectangular spraying pipe mounted on the peripheral frame of the master door of the emergency system, the inner side of the spraying pipe is provided with spraying holes which can spray opposite to one another, the spraying pipe is provided with a switching valve, the master door is provided with an interlocking system, which is interlocked with the switching valve and can open the switching valve when the master door is opened to automatically start an air curtain as well as close the switching valve when the master door is closed to automatically stop the air curtain. By means of the structure above, when miners enter the coal mine underground emergency system and open the master door, due to the open-close linkage of the switching valve of the spraying pipe, the switching valve can control the air curtain to be started automatically after the master door is opened and to be stopped automatically after the master door is closed. The compressed air curtain device of the coal mine underground emergency system can insulate the coal mine underground emergency system from toxic and harmful gas, is simple in structure and reliable in usage and can effectively prevent the external toxic and harmful gas from entering the master cabin of the emergency system and guarantee the health security of personnel in emergency.
Description
Technical field
The present invention relates to a kind of device that enters act of rescue system under coal mine for intercepting toxic and harmful, specifically act of rescue system compresses air curtain device under a kind of coal mine.
Background technology
In recent years, accident of mine disaster took place frequently, and under coal mine, urgent danger prevention guard system is equipped as coal mine safety emergency rescue, and disaster can provide an airtight living space for withdrawing in time the personnel that lock in mine of mine while occurring.Wherein, under coal mine, act of rescue internal system living environment has very important effect for the safety that guarantees miner's life, yet under existing coal mine in urgent danger prevention guard system without any safeguard procedures, therefore tend to make toxic and harmful to enter into urgent danger prevention guard system and jeopardize the healthy and safe of hedging personnel.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of toxic and harmful that can effectively intercept and enters under coal mine act of rescue system compresses air curtain device under the coal mine in act of rescue system.
In order to solve the problems of the technologies described above, act of rescue system compresses air curtain device under coal mine of the present invention, comprise the rectangle spray piping being arranged on main hatch door surrounding frame, spray piping inner side is provided with the spray orifice spraying towards offside, is provided with switch valve on spray piping, is provided with switch valve and carries out chain locking system on main hatch door, when main hatch door is opened, switch valve is opened, automatically move air curtain, while closing main hatch door, switch valve cuts out simultaneously, and air curtain stops automatically.
Described spray piping is made by stainless steel tube, and on spray piping, being provided with switch valve is mechanical switch valve.
Adopt after above-mentioned structure, due to the spray piping with spray orifice arranging, on main hatch door, be provided with the switch valve of spray piping and carry out chain locking system, when miner enters under coal mine act of rescue system, while opening main hatch door, due to the startup and main hatch door phase interlock of the switch valve of spray piping, make after main hatch door is opened, switch valve is controlled air curtain and is started voluntarily, and at closing time, air curtain stops voluntarily.Thereby can deaden toxic and harmful and bring act of rescue system under coal mine into, arrange thus, simple in structure, use reliably, effectively completely cut off outside toxic and harmful and entered in main cabin, guaranteed that hedging personnel's is healthy and safe.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of act of rescue system compresses air curtain device under coal mine of the present invention;
Fig. 2 is the plan structure schematic diagram of act of rescue system compresses air curtain device under coal mine of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, act of rescue system compresses air curtain device under coal mine of the present invention is described in further detail.
As shown in the figure, act of rescue system compresses air curtain device under coal mine of the present invention, comprise the rectangle spray piping 2 being arranged on main hatch door surrounding frame, rectangle spray piping 2 arranges as a whole, spray piping 2 inner sides are provided with the spray orifice 1 spraying towards offside, the quantity of spray orifice 1 can need to be set to a plurality of according to use, on spray piping 2, be provided with switch valve 3, on main hatch door, be provided with switch valve 3 and carry out chain locking system, when main hatch door is opened, switch valve 3 is opened, automatically move air curtain, while closing main hatch door, switch valve 3 cuts out simultaneously, air curtain stops automatically.
In the present invention, spray piping 2 can also be arranged to four air inlet pipelines, be distributed in the surrounding of protective door, on air inlet pipeline, be drilled with according to actual needs the circular hole of some, compressed air is extruded formation air curtain from circular hole, guarantee that compressed air curtain should cover whole main hatch door, thereby intercepted act of rescue system under toxic and harmful invasion and attack coal mine.
Wherein above-mentioned spray piping 2 is made by stainless steel tube, on spray piping 2, be provided with switch valve 3 for mechanical switch valve, on main hatch door, be provided with switch valve 3 and carry out chain locking system, make thus mechanical switch valve and main hatch door form link gear, the unlatching of act of rescue system compresses air curtain device under coal mine of the present invention is realized by mechanical switch valve, when main hatch door is opened, switch valve 3 is opened, in the spray orifice 1 of compressed air from spray piping 2, extrude formation air curtain, thereby guarantee that compressed air curtain covers the main hatch door of act of rescue system under whole coal mine, isolated outside toxic and harmful, it is simple in structure, realized entering under coal mine in act of rescue system of toxic and harmful when intercepting escape personnel and entering escape system, make the inner air that keeps of escape system keep clean, for the normal operation of escape system provides assurance.
