Abstract

The utility model relates to long-range fire-extinguishing equipment, in particular to a rocket fire-extinguishing bomb, which mainly consists of a rocket and a fire extinguisher. The fire extinguisher is arranged in the rocket; the outer casing of the fire extinguisher is spherical; the inside of the outer casing is fixedly provided with a spherical gas nozzle; the spherical outer wall of the gas nozzle is provided with a plurality of jet holes; the jet holes adopt the shape with the inner part contracted and the outer part expanded; the gas nozzle is filled with propellant, an ignition tube, a delay device and a temperature control device; the delay device and the temperature control device are controlled by an integrated block; and fire extinguishing agent is filled between the fire extinguisher and the gas nozzle. Because of the rocket device, the fire-extinguishing bomb can be fired to the fire site tens meters or even dozens of kilometers away. Because the rocket is equipped with the special fire extinguisher, the gas nozzle has powerful jetting capability, thereby leading to the fire extinguishing capability about 10 times of the ordinary fire-extinguishing bomb. With the ignition tube, the delay device and the temperature control device, the latter two of which are controlled by the integrated circuit board, the utility model can effectively control the fire extinguishing time and the blasting temperature.

Description

Rocket fire-extinguishing bullet

Technical field

The utility model relates to a kind of extinguishing device, specifically a kind of long-range rocket fire-fighting equipment.

Background technology

Fire is the formidable enemy of grassland, forest, high buildings and large mansions, is the killer of life, property safety and environmental protection.Usually, closely the fire of Fa Shenging is easier to put out, and for large tracts of land, remote fire, because the fire fighter can not feel simply helpless people near point of origin or zone on fire in face of fire.At present, to the fire extinguishing measure of large tracts of land or remote fire, mainly adopt the method for airplane spray chemical to put out a fire in the world, have weak effect, shortcoming that cost is high.

Summary of the invention

The purpose of this utility model is at the difficult problem of the remote fire extinguishing of present existence, provide a kind of can be at a distance, large tracts of land effectively catches new device---the rocket fire-extinguishing bullet that delivery is launched of fire extinguishing calamity.

The utility model is achieved in that mainly to be made up of rocket and the fire extinguisher that is installed in the rocket, and the housing of fire extinguisher is a spheroidal; Fixing an exhaust gas nozzle in this spheroidal housing, having the spray orifice that contracts and extend out in a plurality of on the spherical housing of exhaust gas nozzle, its import throat opening area is d1: d2=3: 4-6 with the ratio of discharge area; Time-delay mechanism, temperature regulating device and the automatic ignition device of propellant powder, the control of ignition tube integrated package are housed in the exhaust gas nozzle.Between fire extinguisher and the exhaust gas nozzle extinguishing chemical is housed, this extinguishing chemical can be an ammonium phosphate powder extinguishing agent, also can be chemical.

Said fire extinguisher has 1-5, and the housing of fire extinguisher is that aluminosilicate material is made; Exhaust gas nozzle is that alloy steel material is made; Delay time is determined according to the distance between payload-release point and the fire; The control temperature that fires is 80 ± 5 ℃.Said automatic ignition device is by A integrated package, B integrated package, is controlling delay time respectively and is firing temperature.

The rocket fire-extinguishing bullet of the delivery of the utility model emission is owing to adopt rocket means, so fire extinguisher bomb can be transmitted into the scene of fire of tens of meters and even tens of kilometers; Because be equipped with special fire extinguisher in the rocket, its exhaust gas nozzle has powerful jet power, therefore the extinguishing ability that is better than about ten times of common fire extinguisher bombs is arranged; Owing to the time-delay mechanism and the temperature regulating device of ignition tube, surface-mounted integrated circuit control are arranged, thereby can effectively control the time of this facility fire extinguishing and the temperature that fires.

The specific embodiment

Below in conjunction with embodiment of the present utility model of accompanying drawing narration

Fig. 1 shows overall structure, and the housing of rocket 1 is made up of four lobes, and is axial in the rocket 1, and front and back are installed with the device of 3 fire extinguishers 2 and the operation of control rocket: automatic ignition device 5, solid powder column 4, emission jet pipe 3 etc.

Fig. 2 shows extinguisher structure, and the housing 6 of fire extinguisher 2 is a spheroidal, external diameter 200cm, and these spheroidal housing 6 usefulness aluminosilicate materials are made, and help anti-burning, anti-pollution.

Exhaust gas nozzle 8 is installed in the fire extinguisher 2 by fixture 7, and its shell 12 is a spherical, external diameter 100cm, wall thickness 10mm.Be uniform-distribution with 98 circular spray orifices 13 on the spherical housing 12 of exhaust gas nozzle, injection diameter 12mm is " in contract extend out " shape, and its import throat opening area is d1: d2=3 with the ratio of discharge area: 5, as shown in Figure 5.Spray orifice of " in contract extend out " shape like this, improved emissivities greatly---spray powerfully, spray distance, spray area is wide.

The automatic ignition device 11 that propellant powder 9, electric squib 10 is housed in the exhaust gas nozzle 8 and mainly controls by A integrated package 15, B integrated package 16.

Between fire extinguisher 2 and the exhaust gas nozzle 8, ammonium phosphate powder extinguishing agent 14 is housed.

The circuit of Fig. 3, Fig. 4 difference display delayed device and temperature regulating device, these two circuit are controlled the delay time of the chance ignition of catching fire respectively and are met 80 ± 1 ℃ of the fiery temperature that fires by A integrated package 15, B integrated package 16, in time open initiator 17.

After fire took place, the rocket that fire extinguisher is housed was launched into the scene of fire, and its time-delay is opened cap and shed mechanism and four housings of rocket are beaten dried, and fire extinguisher is deviate from from rocket.After the automaton in the fire extinguisher is sensed the information of fire temperature, cause and fire device, a large amount of inert gases that the ejecting extinguishing medicine produces are when exhaust gas nozzle, with the subsonic speed increase of further expanding, slow down in the contraction section supercharging, at the expansion segment decompressing speed-increasing, be kinetic energy through twice acceleration with more enthalpy change, the supersonic airstream that produces in the exhaust gas nozzle forces each spray orifice to spray the powerful air-flow of high pressure simultaneously.Owing to spray gas simultaneously between each spray orifice, under the effect of impacting mutually, repelling mutually, just produce a kind of special High Voltage strong contingent vortex air flow.Because the fire extinguisher housings close is tight---gas is produced bigger hoop Shu Li.Just in a flash at this, High Voltage strong contingent vortex air flow is rolled lift-off from ground burning things which may cause a fire disaster root with flame with the powerful vortex gas of dust cloud dirt that the ammonium phosphate salt extinguishing chemical is injected into mushroom cloud, disappear among the cloud and mist, cloud and mist state extinguishing chemical dust shrouds at the active gene that carries out chain reaction through pyrolytic in flame among the flame and sharply reduces, gas dispels cooling with the heat of comburant as far as possible simultaneously, the extinguishing chemical of cloud and mist covers the comburant crucible zone, in the infiltration solid hole, with " prevention resume combustion ", cooling, secluding air cause the flame anoxic to be extinguished.All that this moment takes place all are chemistry and the dual combined reaction of physics, realize the purpose of " sound fire goes out ".
