The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises a Smoke Sensor 1, and it is arranged on the top in tunnel 2 in the mine, near Smoke Sensor 1 audible-visual annunciator 3 is set.2 bottom or sidewall are arranged with an air bag Storage Box 4 in the tunnel, and Storage Box 4 tops articulate a lid 5.Be provided with an air bag 6 in Storage Box 4, air bag 6 is connected with the gas circuit control device 8 that is arranged between 2 one side apparatus of tunnel in 7 by pipeline.In air bag 6 bottoms one normally closed outlet valve 9 should be set, 2 top and sidewall are provided with 1～3 pressure sensor 10 in the tunnel.One circuit controller 11 is set in equipment room 7, and circuit controller 11 is electrically connected with Smoke Sensor 1, alarm 3, pressure sensor 10, gas circuit control device 8 and outlet valve 9.The tunnel opposite side relative with equipment room 7 is arranged with a by-pass 12, and the import of by-pass 12 is positioned at the front of air bag 6 near the production face end, and the outlet of by-pass 12 is positioned at the back of air bag 6 near the tunnel entrance point.Be provided with 1～3 road barrier 13 in the by-pass 12, be provided with the hermatic door of opening to production face 14 on by-pass 12 and the barrier 13, hermatic door 14 can be closed automatically.Like this after the people ran hermatic door 14, no matter the hermatic door of closing automatically 14 under what pressure condition, all can paste tighter and tighter, and can not allow toxic and harmful pass through.In the import of by-pass 12 and by-pass 12, be provided with light and show direction board 15, to guide the direction of flurried people's escape.
In the foregoing description, the shape of air bag 6 can be various, as long as can stop up whole tunnel after its swollen opening, stops circulation of air to get final product.The set-up mode of air bag 6 can be various; can be without Storage Box 4; and place it in other container; or directly be hung in the pit of tunnel sidewall, but it is interior more safe and reliable to be arranged on a Storage Box 4, and lid 5 protections are arranged; cracky not at ordinary times; when needing, the pressure that air bag 6 swells can open lid 5, and is very easy to use.
In the foregoing description Smoke Sensor 1 and audible-visual annunciator 3 operated by rotary motion in the tunnel 2 top, the two can be set together, and also can divide to be arranged.Pressure sensor 10 can divide top and the sidewall that is located at tunnel 2, and to survey the blowing pressure of air bag 6 from different directions, in case pressure arrives predetermined value, circuit controller 11 just can be controlled gas circuit control device 8 and stop inflation.Above-mentioned Smoke Sensor 1, audible-visual annunciator 3 and pressure sensor 10 have off-the-shelf, can choose according to different needs.
Gas circuit control device 8 comprises air pump and control valve in the foregoing description, and a valve is set on Storage Box 4, and the inner end connects air bag 6 outer ends and connects a tracheae, and the tracheae other end connects air pump, and a control valve is set between air pump and circuit controller.The outlet valve 9 that is arranged on air bag 6 bottoms can make air bag 6 use repeatedly, or inflates experiment, and outlet valve 9 also can manual unlocking.Gas circuit control device 8 such as air pump, control valve and outlet valve 9 can be bought and be connected as required.Equipment room 7 is general at the rear of Storage Box 6, after getting rid of with the accident that swells at air bag 6, opens equipment room 7 and operates.
Above-mentioned by-pass 12 can make in aggregates, also can be that the on-the-spot installation of loose mail is in aggregates, and its side near air bag 6 has anti-air pressure ability, is not damaged by pressure when air bag 6 swells.The by-pass 12 inside and outside hermatic doors of installing 14 can adopt the touch hermatic door of prior art, to prevent to can not find in the dark door handle.
When the utility model uses,, each parts is installed in the tunnel 2 at first according to designing requirement, and along with the interim reach of the reach of production face is installed.In case harmful gas concentration takes place to exceed standard, or gas explosion takes place in indivedual tunnels, gas spreads rapidly, Smoke Sensor 1 just can send signal, and circuit controller 11 guide sound light crossing-signals 3 are reported to the police, and it is air bag 6 inflations that gas circuit control device 8 starts, under the effect that air bag 6 expands rapidly, the loam cake 5 of Storage Box 4 is opened, and air bag 6 trails rapidly the tunnel shutoff in the tunnel, and pernicious gas is blocked isolation.After air bag 6 is filled, contact pressure sensor 10, and signal feedback is arrived circuit controller 11, the air pump of gas circuit control device 8 just is closed, and stops to air bag 6 inflations.The miner who is trapped in the tunnel 2 just can show under the guide of direction board 15 at light, 12 hermatic door 14 enters from the by-pass fast, through by-pass 12, come out to escape relievedly from the rear portion of air bag 6, and needn't worry the invasion and attack of toxic and harmful, thereby avoid miners to suffocate or poison effectively and die, reduced the disaster loss significantly.Simultaneously owing to completely cut off air by air bag 6, the gas explosion of also having avoided airborne comburant oxygen and having taken place once more.
After the careful follow-up in the tunnel is finished, the outlet valve 9 that operating personnel can manually or electronic will be arranged on the air bag 6 is opened venting, return to original state after, close outlet valve 9, close the loam cake 5 of Storage Box 4, promptly finished the entire work process of down-hole smog spacer assembly.
In order to make smog spacer assembly safety, sensitivity, reliable, effectively, should regularly air bag carries out the safety and effectiveness experiment to installing particularly.In gas circuit control device 8, a manual switch 12 can be set, give air bag 6 inflations with booster air pump; Manually boot outlet valve 9 then, give air bag 6 exhausts.
