The present invention compares the good effect that is produced with background technology:

1, can defend the territorial sky effectively.

Fig. 1 is a system construction drawing of the present invention.

Fig. 2 is the constructional drawing of gas furnace 5 among Fig. 1.

Fig. 3 is the constructional drawing of Fuel Tank 8 among Fig. 1.

Fig. 4 is the constructional drawing of Fig. 1 hollow thunder 13.

Below in conjunction with accompanying drawing, the present invention is done to describe further:

Referring to accompanying drawing, fire balloon 1, combustion gas material 5, Fuel Tank 8 and empty thunder 13 quaternities are stacked in rocket shrapnel, the shell shrapnel, and every suit air defence mine is equivalent to a bullet unit, and the big female bullet of a developed country can be loaded onto several, tens air defence mines.Fire balloon 1 is in female bullet the time, lanyard 37 on the pull igniter 21 is in relaxed state, at this moment, unlatching rope 32 on the valve switch 31 also is to be in relaxed state, and valve switch 31 is again the state of killing that is in, so, no matter be at ordinary times, during still female bullet emission or in the ballistic flight, pull igniter 21 can not got angry automatically, valve switch 31 can not opened yet.Even the cas fortuit that pull igniter 21 is got angry takes place, cover because of its hot gas ball cover that does not have source of the gas and pull igniter 21 to be made by fire proofing, the problem of fire can not take place yet, fire balloon 1 still is in a safe condition.

Empty thunder 13 is at ordinary times, and the core bar of spark electric detonator 53 (electrode) is connected with the housing (another electrode) of electric detonator 53 by the conduction spring 54 that is in impaction state, four elastic claws of conductive sleeve 55, makes electric detonator 53 be in the short circuit safe condition all the time.The negative pole of ring piezoelectric crystal 44 is communicated with the positive pole of ring piezoelectric crystal 44 by piezoelectric ring 12, screw 49, conductive shield 60, conductive sleeve 55, the housing of electric detonator 53, detonator seat 9, detonator marshall springs 52, thunder body 38, makes the positive and negative electrode of close-up crystal unit 44 also be in the short circuit safe condition.Because the bottom of detonator seat 9 is thicker, the metal of the fuze body 42 around detonator 53 is also thicker, so electric detonator 53 is to be in the flame proof position.On this position, in case electric detonator 53 self-destructions, the explosive in the empty thunder 13 can not be detonated yet.

When the emission of female bullet, the inertia tube 47 in the empty thunder 13 overcomes following of the drag of inertia spring 48 under the effect of linear inertia power, thus release steel ball 50.Steel ball 50 rolls in the hole of inertia tube 47 along the inclined hole of fuze body 42.When the force of inertia of female bullet emission disappears, inertia tube 47 carries steel ball 50 rises to the hole under the effect of inertia spring 48 summit, the inertia insurance of this space-time thunder 13 is freed, but detonator seat 9 is blocked by Fuel Tank 8, above being pressed in tightly by detonator marshall springs 52 again, make the conduction spring 54 more much smaller than its drag be in impaction state, electric detonator 53 still is in short circuit, flame proof position, ring piezoelectric crystal 44 also is in short-circuit condition, so the incomplete arm of empty thunder 13.When female bullet is launched, also stressed following of backing pin push pedal 57, but do not go owing to being blocked down by the circular groove of detonator seat 9, therefore before the fuse arm, backing pin push pedal 57 is blocked lock all the time and is protected pin 58, make its circular groove that can not enter detonator seat 9 under the effect of shell fragment 56, lock is protected pin 58 and is placed on middle opening in fuze body 42 holes of T type groove, also can not descend seat.Ring piezoelectric crystal 44 also can be stressed, limits and inactive but be insulated ring second 36, and insulating collar second 36 and insulating collar first 23 all are glued together with thunder body 38.

When mother flicked logical sequence, air defence mine was pushed away with buster by female bullet and is thrown in the air.During greater than air resistance, the fire balloon 1 of air defence mine, gas furnace 5, Fuel Tank 8, empty thunder 13 still are stacked together and move along directive as slinging force.When slinging force equals air resistance, 8 poles 20 of gas furnace 5 are launched around arm pin 19 outside upsets under the effect of torsion spring 24, the whereabouts air-flow begins to enter fire balloon 1, make it begin to charge into natural air, slowly heave, the groove of pull bar 2 this moment on the effect lower edge pole 20 that is connected stay cord 3 with fire balloon 1 done outside stretching routine.Much more more and more natural air pours in the balloon, makes it slow down the descending speed of fire balloon 1 and gas furnace 5 as parachute.But Fuel Tank 8 and empty thunder 13 are not obstructed, and descend with the speed of free-falling body, thereby make bonded assembly valve opening rope 32 between Fuel Tank 8 and the gas furnace 5, and the lanyard 37 of pull igniter 21 produces tensile force.Under the effect of this power, the valve switch 31 of Fuel Tank 8 rotates around the mandrel in the eccentric wheel type valve switch 31, and vent plug 29 is risen under the effect of spring 28.Autogas enters pressure maintaining valve 34, Gas Pipe 6, air blast nozzle 7, enters at last in the air cavity of combustion gas body of heater 16.Meanwhile, after the lanyard 37 of pull igniter 21 was pulled, pull igniter 21 flame was obliquely upward lighted blue gas.Flame makes fire balloon 1 produce buoyancy aloft at fire balloon 1 bottom fuel.The size of thermal current can regulate by gas quantity adjust bar 18 in advance.Hang time length depends on the volume size of Fuel Tank 8.In like manner, poor because of the descending speed between empty thunder 13 and the Fuel Tank 8, make the hanging mine rope 11 on the hanging mine ring 12 that is tied to Fuel Tank 8 begin to stretch, and under empty thunder 13 actions of gravity, detonator seat 9 overcome the drag of detonator spring 52 and rise under the effect of hanging mine rope 11.At this moment, conductive sleeve 55 still is pressed on conductive shield 60 position contacting motionless under the effect of elastic resistance of conduction spring 54, and electric detonator 53 breaks away from four elastic claws of conductive sleeve 55 in company with detonator seat 9 and rises, and goes straight up to when detonator marshall springs 52 spring coils kill state and ends.In detonator seat 9 uphill process, drive backing pin push pedal 57 along the T type groove upward movement on the fuze body 42, make it move to the restriction that breaks away from T type groove and fall in the cavity of fuze body 42 by the circular groove on it.Lock is protected pin 58 and is moved right under the effect of shell fragment 56, is against on the round wall of detonator seat 9.It is exactly that the position is freed in empty thunder fuse gravity insurance that detonator seat 9 rises to 55 4 elastic claw positions of electric detonator 53 tube walls disengaging conductive sleeve.When this position, the short circuit safety position of electric detonator 53, close-up crystal unit 44 is all destroyed, and simultaneously, the two poles of the earth of the two poles of the earth of electric detonator 53 and close-up crystal unit 44 are connected.Insulate by insulating collar the third 62, insulating cove 64, insulation spiral shell 65, insulating collar first 23 and second 36 between the two poles of the earth.Conductive shield 60 is fastened on respectively on thunder body 38 and the fuze body 42 by insulation screw first 61 and second 63.In the arm position, the hole wall of fuze body 42 is very thin, and electric detonator 53 is in the position of can detonate fully sky thunder powder column first 39, second 40.

When fire balloon 1, gas furnace 5, Fuel Tank 8 and the empty thunder 13 of air defence mine aloft launched, the interception net 15 that hangs on the fire balloon 1 also launched under lead sticks together 14 action of gravity.The bottom of net 15 is connected with four insulation screws 63 of four nylon wires below empty thunder 13.

When the guided missile of airflight, opportunity of combat high-speed crash were to empty thunder 13, conductive shield 60 made it produce high-tension current at the pressurized place by piezoelectric ring 12 compression close-up crystal units 44.The positive pole of high-tension current extremely links to each other with the housing one of electric detonator 53 by thunder body 38, detonator marshall springs 52, detonator seat 9.The negative pole of high-tension current extremely links to each other with the core bar one of electric detonator 53 by piezoelectric ring 12, screw second 49, conductive shield 60, conductive sleeve 54, conduction spring 54.The two poles of the earth of electric detonator 53 produce electro spark under the effect of high-tension current, thereby detonate electric detonator 53 powder charges, ignite powder column first 39, second 40.After powder column 39, second 40 blasts, make annular arrangement cavity liner 41 that high-speed crash takes place on top, produce disk shape metal jet, play armor-penetrating effect attacking flyer; Make the steel ball that gives in the plastics steel ball sleeve of putting 46 all come target of attack in the bottom as injuring unit together with thunder body 38 fragmentations, close-up crystal unit 44, piezoelectric ring 12 fragments.Empty thunder 13 aloft explodes and is scattering into the effect of ground fragment owing to air resistance, and its kinetic energy is less.Damage effect is not strong.

Empty thunder 13 is intercept point just aloft, has added the interception face that just forms tens sq ms behind the interception net 15, no matter any position that target is run into net 15 all can be got rid of thunder band and be struck on the flyer, plays the effect of " drawing thunder is harmful to the health ".Attack on the border line of direction near enemy plane and dispense several ten thousand on the course line that may pass through, hundreds of thousands of sends out air defence mine, just can realize aerial defence effectively.

Because the electric detonator 53 of empty thunder fuse adopts the full-shield structure on empty thunder 13 structure designs, strengthened the safety in utilization of empty thunder 13.Again because empty thunder fuse adopts the detonate energy of close-up crystal unit 44 as electric detonator 53, when solving high-speed crash, parameters such as the voltage that detonates of piezoelectric modulus, electric capacity and electric detonator 53 that can be by regulating crystal 44 on designing, safety voltage must reliably send out point, the contradiction that can not get angry during low speed collision.Sky thunder 13 is aloft bumped against in twos, in dropping process, run into when trunk, wall and mal posture are run into ground and all can not explode.

When air defence mine landed, because the double action of air resistance and the less buoyancy of fire balloon, descending speed was slower.At first be sky thunder 13 first kiss the earths (water surface etc.), it is loose that hanging mine rope 11 is taken place, and detonator seat 9 returns to the safety position before the emission very soon under the effect of elastic resistance of detonator marshall springs 52.And lock is protected pin 58 and is inserted in the circular groove of detonator seat 9 under the elastic force effect of shell fragment 56, and detonator seat 9 is locked in safety position.At this moment, have staff lifting thunder rope 11 to get rid of immediately and swing, empty thunder 13 can arm yet, the safety after having guaranteed to land.As fire balloon 1 or interception net 15 that air defence mine occurs hang on the branch or on the electric pole, and empty thunder 13 is also not serious when being suspended in aerial sight, because of it insensitivity performance that possesses, can not explode as long as just impact fast without weight.Can be earlier with the stock object with empty thunder 13 to high 50 millimeter of pop-up, make detonator seat 9 be returned to safety position, and then take off and get final product.

The present invention can also adopt manpower to aerial directly mine-laying: allow the people that the bottom of fire balloon 1 is launched earlier, spur valve opening rope 32 and pull igniter rope 37 simultaneously with hand then, gas furnace 5 is lighted to fire balloon 1 filled hot gas, when treating that it rises, hand-held arm stay cord discharges its no pulling force earlier, waits to rise 50 meters later on again with sudden forces pulling stay cord 51, inertia tube 47 overcomes spring 48 drags and moves down under the manpower pulling, discharge steel ball 50.Fuse is comprehensive arm under empty thunder 13 actions of gravity.All the other processes are identical with the dispensing minelaying of female bullet with action principle.

The top of fire balloon 1 can be coated with camouflage color or khaki, side and following milky or the sky blue of then being coated with, on high-speed moving object, be difficult to find float forwardly than wisp, add just more difficult discovery behind the protective coloration, treat also to hide when finding not as good as.

Air defence mine can be repeatedly used, except changing pull igniter and again the aeration, most parts can directly repeat with or repair the back and use.The inertia insurance and the backing pin push pedal that are empty thunder 13 need manual reset, conduct a survey slightly after resetting and can reuse.
