Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described with embodiment.
As shown in Figure 1 and Figure 2, sets forth the structural representation of the fire control shell of the present invention and sectional view, its by body 1, rear cylinder body 3, conveyor front barrel 4, explosive 5, fin 6, ignition charge, time delay lead-in wire 8, immediately going between 9, pushing igniter and being positioned at the igniter of front end forms, shown body 1 is made up of fire-fighting material, the inside of body 1 is central cavity 2, rear cylinder body 3, conveyor front barrel 4 are individually fixed in rear end and the front end of body 1, and all communicate with central cavity 2. The quantity of fin 6 is multiple, and multiple fins 6 are uniformly distributed in the periphery of rear cylinder body 3, is conducive to strengthening the stability of shell flight course and extending flying distance. Explosive 5 is arranged in central cavity 2, after explosive 5 is detonated, for by fire-fighting substance splash in the surface of the object that catches fire, the object that catches fire is fire-retardant, to realize fire-fighting fire extinguishing.
Being filled with ignition charge 7 in the end of shown rear cylinder body 3, ignition charge 7 is connected with explosive 5 by time delay lead-in wire 8. Push igniter to be made up of base plate 14, connecting plate 15, piston 16, back-moving spring 18, base plate 14 is circular, the number of connecting plate 15 is equal with fin 6 or doubles, and the rear end of connecting plate 15 is fixed on base plate 14, and by connecting, steel wire 17 is fixing with corresponding fin 6 to be connected in front end.Piston 16 is fixed on the central authorities of base plate 14, and corresponding with the internal cavities of rear cylinder body 3, and the front end of ignition charge 7 is provided with dividing plate 20, and the central authorities of dividing plate 20 are through hole. When piston 16 moves towards ignition charge 7, due to the stop of dividing plate 20, it is produced extruding and ignites.
Back-moving spring is arranged between base plate 14 and fin 6 or rear cylinder body 3, under the effect that base plate 14 is not subject to ectosome, is used for ensureing to remain certain distance between piston 16 and ignition charge 7, it is ensured that explosive 5 is not ignited. Meanwhile, the connection steel wire 17 before connecting plate 15 and fin 6 plays further safety effect, it is to avoid piston 16 and ignition charge 7 come in contact. In order to ensure that the ignition charge 7 in rear cylinder body 3 is ignited, piston 16 offers the air-vent 19 communicated with the external world, in order to ignition charge 7 communicates with extraneous fuel gas, is ignited smoothly.
Being provided with igniter on described conveyor front barrel 4, igniter is made up of ignition charge 7, retainer ring 10, piston 11, arc cap 12 and back-moving spring 13, and ignition charge 7 is arranged in conveyor front barrel 4, and ignition charge 7 is connected with explosive 5 by instant lead-in wire 9. Retainer ring 10 is matched by the inwall of screw thread with conveyor front barrel 4, and piston 11 is through the internal cavities of retainer ring 10, and towards ignition charge 7. Arc cap 12 is fixed on the outer end of conveyor front barrel 4, and back-moving spring 13 is arranged between arc cap 12 and retainer ring 10, it is ensured that when arc cap 12 does not contact with external object, and piston 11 and ignition charge 7 exist a determining deviation, and will not ignite ignition charge 7. Shown conveyor front barrel 4 is provided through the insurance locking bolt 21 in piston 11, artificially opens in use, more ensure that safety when not using.
The fire control shell work process of the present invention is as follows: in air flue under the thrust of gas, base plate 14 advance the puck, while back-moving spring 18 is compressed, the connection steel wire 17 that connecting plate 15 and fin 6 fix disconnects, ignition charge 7 in rear cylinder body 3 is lighted by piston 16, fin 6 and cylinder 3 are produced thrust by dividing plate 20 and base plate 14 by piston 16 simultaneously, and under the combined effect of this thrust and gas, body assembly flies out. Advancing assembly (14,16,18,15) to separate with body assembly, after going out thorax, speed falls again respectively respectively.
In the process that fire control shell flies out, time delay lead-in wire 8 constantly burns. After fire control shell drops down onto fire area, time delay lead-in wire 8 burns totally and the explosive 5 that ignites, and is come by the fire-fighting substance splash in body 1 under the effect of explosive 5, it is achieved fire extinguishing. Even if time delay lead-in wire 8 fails to ignite explosive 5, after the arc cap 12 of body 1 front end contacts with ground or other objects, by piston 16, the ignition charge 7 in conveyor front barrel 4 is ignited, and then lead to explosive 5 is lighted.
