Abstract

An explosion method for extinguishing the fire accident of forest features that the fire-extinguishing grenade, shell or bomb is thrown in the fire field, and the violent vibration and high-pressure and-speed air waves generated by explosion are used to extinguish the fire accident.

Description

Method and fire extinguisher bomb are put out in a kind of forest fire

Technical field

The present invention relates to a kind of forest fire and put out method and Fire extinguisher, especially relate to a kind of method and fire extinguisher bomb that utilizes explosion method to put out a forest fire.

Background technology

Forest fire, comprise virgin forest, inferior forest, the big fire on shrub and firewood forests, grassland and grassland, madness is wreaked havoc all over the world for many years, and state's many places occurrence of large-area forest fires such as the U.S., Mexico, Australia, Spain, Indonesia were only just arranged in 2003.China also has many places that forest fire takes place.Forest fire often causes huge resource and property loss and environmental pollution, even casualties, is big public hazards in fact.At present, the method that puts out a forest fire has following several: the things such as the instrument of swatting of hand-held branch or similar mop are swatted fire extinguishing; Carrying the minitype motivation wind fire-extinguisher on the body puts out a fire; Outside the fire district, cut down out an isolation strip, isolated+burning things which may cause a fire disaster, prevent propagation of flame; Artificial or airborne dispensing extinguishing chemical fire extinguishing; Helicopter and fire fighting truck fire extinguishing water etc., these extinguishing methods all have certain effect, but adopt the branch branch to swat or method fire extinguishing such as wind fire-extinguisher, and people and fire are zero distances, even among the encirclement of fire, the casualties of putting out a fire is difficult to avoid; Artificial or airborne dispensing extinguishing chemical fire extinguishing, methods such as helicopter and fire fighting truck fire extinguishing water, fire-fighting efficiency improves, and is also safer to the fire extinguishing personnel, but fire extinguishing cost height, for large-area forest fire, the fire extinguishing effect still owes desirable.

Summary of the invention

The object of the present invention is to provide a kind of safe and reliable, the fire extinguishing cost low, method and Fire extinguisher are put out in the forest fire of good extinguishing effect.

The objective of the invention is to be achieved through the following technical solutions: destructor is thrown in the scene of a fire, implement to ignite, utilize violent vibrations that the destructor blast forms and high pressure, high speed blast, put out a forest fire.

Blast is the process of discharging out huge energy moment towards periphery.In the time of blast, can produce violent vibrations, and the gas that expands rapidly to around expansion, extruding and to form huge blast be shock wave, violent vibrations and powerful shock wave can make the branches and leaves that burning come off, fray-out of flame, or lifted from the attachment and go out.

Described destructor can be common military grenade, shell, bomb etc., and to manufacture the fire extinguishing destructor that can not produce shell fragment be fire extinguisher bomb but the shell case of preferably manufacturing specially is non-cast iron materials.

The making of fire extinguisher bomb: the selection of (1) fire extinguisher bomb powder charge can be used civil blast materials such as ammonium nitrate and rock ammonpulver, but preferably use TNT powers such as (TNT) big, be convenient to the explosive that transports, make and launch; The powder charge equivalent, every piece of fire extinguisher bomb should be controlled between 0.5 kilogram-10 kilograms; (2) selection of shell case material is because of being the usefulness of fire extinguishing, not to be used to kill and wound enemy's effective strength, explosion time does not need to produce shell fragment, so needn't cylinder iron do shell case, as long as can make it in launch and flight, keep an integral body, when not launched the influence of HTHP just, therefore, can select for use sheet metal (for example sheet metal) or other suitably can not produce a large amount of shell fragments metal, nonmetallic materials manufacture shell case; (3) structural design can adopt and military grenade, shell, structure that bomb is identical, (is used to throw, with detonator, fuse cord, draw fire ring by explosive, shell case, priming device; Be used for cannon emission, use fuse) composition; For example, the fire extinguishing grenade is thrown with hand, gets angry when selling, and adopts time-delay (determining certain hour) blast mode, as common grenade, draws fire back 3-3.7 to explode second; The extinguishing cannonball that equivalent is big, bomb, generally with the cannon emission, aircraft is thrown in the air, and fuse then is installed, and explodes during contact target.

Described fire extinguisher bomb can be produced in batches by factory's typing.

The emission of fire extinguisher bomb and input: should be according to width and the definite emission of height of depth and flame or the destructor of input right quantity and explosive equivalent of the intensity of a fire, the explosive equivalent that every square metre of scene of a fire of average area is thrown in, be preferably TNT 40-50 gram, or ammonium nitrate or rock ammonpulver 70-90 gram---very few, be difficult to reach and put out effect, too much, can improve the fire extinguishing cost.Emission or input mode have multiple, for example, free-hand throwing, rifle grenade and rocket launcher emission, the mortar emission, helicopter input etc., above-mentioned several all in visual range, effect is the most directly perceived, does not generally need the emission of heavy caliber and long-range gun; If scene of a fire area is very big, can adopt the mode of rocket delivery mine to launch, or multiple mode and usefulness, a large amount of, multiple destructor " in full flourish " in the scene of a fire explodes in full preparation, can reach the effect of putting out the extensive forest fire rapidly; Multiple spot is thrown in, and point of impact should as far as possible evenly distribute.

Behind the big fire blackout, clear up and sweep the fragmentary and residual flame in the scene of a fire, available small-sized fire extinguisher bomb or wind fire-extinguisher are removed.

Because the moment blast shock wave that destructor blast of the present invention forms is more much bigger by force than the wind-force that wind fire-extinguisher produces, but also can produce violent vibrations, thereby the fire extinguishing effect is quick much more remarkable than wind fire-extinguisher.

Because explosive is with low cost, extinguishing device is simple for production, and the fire extinguishing effect is very significantly quick, and the fire extinguishing cost is lower.Calculate that according to experimental result the equipment cost that puts out one mu of forest scene of a fire is about 500 yuan.

Use the inventive method puts out a forest fire, and the personnel that put out the fire can keep being no less than 30 meters distance at least with the scene of a fire, therefore, are safe to the personnel of putting out the fire.

The specific embodiment

Experiment 1

With branch is that main dried firewood and leaf, cogongrass etc. pile 3.5 meters of diameters, thick 50 centimeters dried firewood and leaf, cogongrass heap, light, this moment, flare was up to more than 3 meters, to throw in the scene of a fire with the destructor that No. two rock an-tnt-oil explosives of 500 grams are made, implement to ignite, faggot and fiery ash flash, and flame extinguishes immediately, only remaining a small amount of obviously waning moon type ember band (about 70 centimeters of ember band the widest part) of decay.

Experiment 2

The scene of a fire is provided with experiment 1.To throw in the scene of a fire for 2 pieces with the destructor that No. two rock an-tnt-oil explosives of 300 grams are made, and implement to ignite, faggot and fiery ash flash, and flame all is extinguished immediately.

Experiment 3
