Abstract
The utility model discloses an air curtain barrier device of a mine-used lifesaving cabin. The air curtain barrier device comprises a pipeline, wherein the pipeline is arranged around the inner side edge of a doorframe of a transition cabin and is provided with a plurality of small air outlet holes. The pipeline is connected with a control valve through an air inlet pipe, the control valve is arranged on a fixed base on the outer side edge of the doorframe, and a valve rod penetrates through the fixed base and is connected with an elastic clamp on the fixed base. The air curtain barrier device of the mine-used lifesaving cabin can effectively prevent outside toxic and harmful pollutant from entering the cabin, and has the advantage of good safety protection property.
Description
Technical field
The utility model relates to a kind of mining survival capsule, is specifically related to a kind of air curtain baffling device of mining survival capsule.
Background technology
Incident mining accident takes place frequently in the coal production process, and cause a tremendous loss of lives is the safety problem that perplexs coal industry in recent years always.Owing to coal mining accident exists that destructive power is big, reason is complicated and is prone to cause characteristics such as Secondary cases accident, make mine disaster that the external world, back take place and in time to launch rescue.So in the mine underground work face place possess resistance to compression, gas defence, waterproof, heat insulation and can provide the escape capsule of essential life condition to be very important.Mine rescue capsule is the safe confined space that a kind of miner that can't in time withdraw after having an accident for mine provides; Externally can resist blast impulse, high-temperature flue gas; Isolated toxic and harmful; Internally can remove toxic and harmful, win long life span for stranded miner provides oxygen, food and water.Simultaneously, trapped personnel can also be through communication monitoring equipment in the cabin, the extraneous rescue of guiding.Therefore, all drop into a large amount of man power and materials both at home and abroad mine rescue capsule is used development.
Mining survival capsule can be divided into fixed and portable two types.Owing to portable survival capsule can move along with the transition of operation place, can change decorating position as required, have convenient, flexible characteristics, so use extensive day by day.Fixed or portable mining survival capsule all is made up of transfer chamber, accommodation basically.Transfer chamber is that the hedging personnel remove the important cabin body that the health pollutant gets into accommodation; But because the transition hatch door of present mining survival capsule is not provided with the device that effectively stops extraneous poisonous and harmful substance; Pollutant is prone to get into transfer chamber and accommodation with opening of hatch door, thereby influences the healthy of hedging personnel.
Summary of the invention
The utility model technical problem to be solved provides a kind of air curtain baffling device that can effectively stop environmental contaminants, mining survival capsule that the security protection performance is good.
For solving the problems of the technologies described above; The technical scheme that the air curtain baffling device of the mining survival capsule of the utility model is adopted is: it comprises the pipeline that is provided with many little ventholes that is installed in around the transfer chamber doorframe inner side edge; This pipeline is connected with control valve through air inlet pipe, and control valve is installed on the holder of doorframe outer side edges, its valve rod passes holder and be connected with elastic clip on the holder.
The aperture of described venthole is towards outdoors, and the aperture face is not more than 45 ° with the angle of door vertical plane.
Because technique scheme is installed the pipeline that is provided with many little ventholes around the doorframe inner side edge, when opening the transition hatch door, elastic clip is upspring; Place the pressure-air in the cabin to get into pipeline through control valve; And from many little ventholes, blow out, thereby form air curtain, therefore; The utility model can stop effectively that extraneous hazardous contaminant gets in the cabin, has the good characteristics of security protection performance.
Description of drawings

Fig. 2 is the structural representation of the control valve in the embodiment shown in Figure 1;
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Visible by Fig. 1, Fig. 2 and Fig. 3; The air curtain baffling device of the mining survival capsule of the utility model comprises the pipeline that is provided with many little ventholes 12 that is installed in around the transfer chamber doorframe inner side edge; This pipeline 2 is connected with control valve 4 through air inlet pipe 3, and control valve 4 is installed on the holder 5 of doorframe outer side edges, its valve rod passes holder 5 and be connected with elastic clip 6 on the holder 5.
The aperture of venthole 1 is towards outdoors, and the aperture face is not more than 45 ° with the angle of door vertical plane.
When opening the transition hatch door, elastic clip 6 is upspring, and pulls out control valve 4 valve rods; Open valve, place the high pressure empty bottle inner high voltage gas in the cabin to get into pipeline 2, and from little venthole 1, blow out through air inlet pipe 3, control valve 4; Formation have certain pressure towards outdoors air curtain; The hedging personnel can get into, and pollutants such as extraneous toxic and harmful, dust effectively are blocked in out of my cabin, have the good characteristics of security protection performance.
