Needle 45 heads are conical, on the taper seat below the conical head the oblique air inlet that is tilted to are arranged; Needle 45 taper seats are cylindrical with the lower part, on the excircle of column part caulking groove are arranged, and caulking groove is equipped with sealing ring; It is thread segment that needle 45 is positioned at the following stage casing of sealing caulking groove; The end section of needle 45 is external portions that external diameter strengthens.Needle 45 has axle center hole; This hole and head are obstructed, are communicated with oblique air inlet, are the silk hole in needle 45 bottoms, connect usefulness with external charger.The conical head of needle 45 is assemblied in axle center hole reducing place, the cooperation with it of introducing joint 46.The external thread section in needle 45 stage casings is assemblied on the internal thread of introducing joint 46 axle center hole bottoms.When needle 45 is in when upwards screwing, the head of needle 45 is closed with the filling channel at the axle center hole reducing place that introduces joint 46.When needle 45 is in when unscrewing downwards, the head of needle 45 is communicated with filling channel between the axle center hole reducing place that introduces joint 46.
Introduce joint 46 stage casings and pass pipe collar III (69) and introducing folder packing ring and sealing ring between the big lower semisection end face of joint 46 external diameters and the pipe collar III (69), push up through the lower end that sealing mat, needle 45 will be introduced joint 46 by the cover of inflatable cover assembly 47 and be fixed.Inflatable cover assembly 47 is by nut on the inflatable cover base plate 44 and the screw 70 fastening downsides that are connected in pipe 65 that are welded in pipe 65 downsides of adapter cavity assembly 6.
Operating principle: this device is fixed on the back by anchor pole.Form air-shock wave and spark sharp side when blast in the down-hole, shock Wave speed is far longer than the spread speed on spark sharp side.When shock wave arrives shock wave receiving system 1, be delivered to locking device 5 by push rod, trigger main body assembly 4 actions and cause the eruption of fire extinguishing powder.The result forms concentration in the tunnel be 80 grams/every cubic metre, the reliable fire extinguishing powder cloud layer of length above 30 meters.Fire extinguishing powder cloud layer can suspend in air 15 minutes, had made it time enough and had hindered and the sharp side of stamping out the flames, and the communication process of blast in the tunnel stopped, and stoped fire to continue to spread expansion, isolated and suppress blast minimizing explosion hazard effectively.
The realization of this device action depends on the triggering of the compressed air and the locking device 5 of 10 li of high pressure air cavity assemblies.Compressed air charges into the high pressure air cavity by aerating device 7, and its pressure should reach the regulation requirement, and the pressure size is shown by pressure meter 34.When shock wave arrives, the shock wave receiving system receives shock wave and impact energy is delivered on the hoop 51 of packing into of locking device 5 by push rod, promote sliding sleeve 52 axial displacement backward, the cavity of sliding sleeve 52 moves to steel ball hole Q place, steel ball 56 in radial hole Q by piston 57 back segment jack-up, make steel ball 56 no longer to 57 position-limiting actions of piston, piston 57 is removed the position of shutoff bleeder port X in high pressure air cavity compressed air pressure lower edge axial advancement.High pressure air cavity compressed air eight bleeder port X, adapter cavities on air jet pipe 54 enter outer cover assembly 9, make the fire fighting powder of outer cover assembly 9 spouting under compressed-air actuated effect, form fire extinguishing powder cloud layer in the tunnel.
