Abstract
The present invention relates to a method for locating and/or extinguishing fires, wherein the method is mainly intended for fighting violent and large-scale fires in relatively inaccessible areas. This method comprises applying a combined action directly onto the fire region using a fine-dispersion air cloud (4) of a flame-retardant composition, an air shock wave (5) and a rapid air and detonation-product head which are all generated by the explosion of a dispersion load (15) in a fire-extinguishing device (1) when the latter approaches the burning region. The fire-extinguishing device (1) comprises a vessel made of an ecologically clean material that is filled with a flame-retardant composition. The vessel is fitted with a dispersion charge and a sensor for a given parameter, such as altitude, said sensor being set at a given parameter (altitude) value. When the fire-extinguishing device (1) approaches the burning region and when the value is reached, the dispersion load (15) explodes in a given fire sector. The dimensions and locations of the sectors where the fire must be extinguished are selected according to the type of fire and to the dimensions of the fine-dispersion cloud (4) of flame-retardant composition which is to be created.
Description
The present invention relates to environmental ecology, fire extinguishing means, or rather, the method and apparatus that relates to limitation and/or stamp out a fire, can be used for putting out effectively large-scale and strong fire, comprising forest fire and forest-prairie fire, and no matter be that ungetable area (the precipitous mountain ridge, the virgin forest of no road geographically takes place, matto) fire, or the fire of dangerous matter sources (explosive, high temperature) is approached in the position.
Press Combined extinguishing effect the best way for using air-shock wave, it be cause with explosive and advance towards burning things which may cause a fire disaster or along the burning things which may cause a fire disaster forward.
Putting out of known limitation mainly is that the method for Forset and glassland fire is to set up the gas air cloud before the burning forward, it is dissipation gas shape propylene oxide to the combustion zone drift in air, and blast under the effect in thermal pulse when arriving combustion zone (SU No.1111 292).
Because the effect of air-shock wave makes the flame fragmentation, make little combustion debris and burning and the material that glows is transferred to combustion zone inside by the burning forward, and dispose the lip-deep combustible material before the burning forward.In addition, temporarily stopping oxygen because the non-flammable gases that the blast of gas air cloud forms makes rarefaction of air spreads to combustion zone.
Under the high situation of the probability of blasting, might reach the whole above-mentioned effect of air-shock wave.Yet the gas air cloud will burn under situation preferably, rather than blast, because freely drift about of cloud mainly is upwards to carry out before the fire forward, forms the loss of cloud, thereby has reduced the concentration of explosive substance, and gets rid of the generation of exploding.
Known a kind of device (FRNo.2643820) that the fire of dangerous matter sources is approached in the unattainable geographically area of generation or position that limits to and put out.
Known a kind of fire extinguisher plant that is called as the water bomb uses aircraft or heavy helicopter to transport, and throws in to burning things which may cause a fire disaster.The characteristics of this water bomb are to have the cylindrical container made from sheet steel with holes, are used for filling extinguishing fluid and air-out, and this basin has half the breach that the degree of depth equals steel plate thickness on its whole sidewall.Can make water, infiltrate and carbon dioxide as extinguishing fluid.The water bomb is thrown in the back makes the water bomb cracked owing to metal has to weaken in advance to distinguish when contacting with ground, and extinguishing fluid is spread across on the burning things which may cause a fire disaster.
The shortcoming of this known fire extinguisher plant is that the cylinder basin is cracked in advance with being positioned at obstacle bump before the fire zone probably, for example with thick branch bump, has so just reduced the fire extinguishing effect.
In addition, the extinguishing fluid of shedding spills after housing clashed into and be cracked at the fire zone skewness.
This device does not also stipulate to use other extinguish materials except above-mentioned, thereby has limited its field of application greatly.
In order to put out forest fire (top or comprehensive), be extensive use of to set up the method for fire-proof curtain, promptly utilize the system of confined explosion and spray the time-delay combined action that extinguish material combines.
Known a kind of method of limiting to and stamping out a fire be by portable salvo firepower grenade instrumentation transport fire extinguisher plant (SU, No.1789232).
The fire extinguisher plant of realizing this method is made the bullet by the portable grenade instrumentation emission of ground or space base.
Above-mentioned bullet is equipped with the housing of being made up of two half blocks, and when the dynamite container explosion time that is positioned at the warhead axis center, two half blocks are opened, and explosive detonates by the signal of the thermal transmitter that is in the bullet front portion.Arranged the group system of the element bundle form of band explosive and extinguish material along the center dynamite container, and element bundle itself along an axis with the form of bale packing serial arrangement each other.Whole elements of group system have sensor heat or inertia of oneself.Two half blocks of housing are equipped with brake equipment (parachute) with the assurance safe landing, and in the bullet bottom jet engine are housed.
Use the extinguishing method of above-mentioned bullet as follows.When bullet flew to the fire forward, the center dynamite container detonated by the signal of the thermal transmitter of front portion, and two also concerted actions of half block of housing hit the silk subsequently, discharged the element bundle simultaneously, and this element bundle freely falls, and arrives fire zone.Part element is used to put out the bottom fire, and they are equipped with inertial sensor, and concerted action takes place when making impact with the ground.Another part element is started by the thermal transmitter that is adjusted to the different temperatures system at the tree crown place.Can infer that the time-delay combined action that utilizes system of confined explosion and sprinkling extinguish material to combine can guarantee to stamp out a fire effectively.
This method and realize that the device of this method has a series of shortcomings reduces its validity greatly and increases loss in its implementation process.Have two types composition element (extinguish material of center dynamite container and band explosive) and their sequence starting has limited air-shock wave and extinguish material disperses according to place that fire is worked and time.May impel the individual areas resume combustion like this and make fire continue to spread, because only smashed flame in these zones, and burning things which may cause a fire disaster is not isolated, and is not cooled off by extinguish material yet.
Use salvo firepower system to transport the effect that composition element to fire zone also reduces said method, because fixedly must have necessary auxiliary device (driving engine, housing are opened with center dynamite container, parachute) under the bore condition at rocket and bullet.The packing factor of the used instrument that transports is that load (extinguish material and filling explosive) is low with the ratio that transports the instrument total weight, the loss when having increased fire extinguishing greatly.
In addition, press area and implement aiming when using salvo firepower system, this may be bad to the effect of limitation fire, because at this moment must at first stop advancing of fire forward (live wire), rather than suppresses flame on the area of fire spread.
The significant drawback of above-mentioned known method be surrounding environment by gross pollution and destruction, promptly a large amount of fragment that forms by usually with metal housing and composition element concerted action the time pollutes.
It also is no small danger that fire zone is buried land mine by the composition element of the filling explosive of concerted action not, because said apparatus is not equipped with the sensor of the backup that causes that element is ignited when arriving ground.
Another is mainly used in the limitation of forest and the known method that stamps out a fire uses air-shock wave before also being based on the fire forward, to set up the higher-pressure region (SU, No.1834 667) of extending along the width of height.
Above-mentioned known method is to arrange a large amount of fire extinguisher plant and detonating charge on the tree crown of following the tracks of fire forward approach.First fire extinguisher plant loaded with liquid fuel also is equipped with the disperse explosive.Instruction by the operator is ignited the disperse explosive with the sequence starting fire extinguisher plant by control signal near the fire forward, at this moment form the fuel-air cloud of thin disperse.Then, through tens of milliseconds of clocks, make above-mentioned air cloud blast by detonating charge, at this moment the forward of the air-shock wave of Xing Chenging can destroy easy firing thing, tiny branch, dried leaf, thick grass and bottom flame, forms fire guard.
Used fire extinguisher plant is made the form of container, and its inner disperse explosive of placing is liquid hydrocarbon fuels (for example, ethylene oxide) around it, and disperse explosive initiation device connects with the control signal circuit that is positioned at the instruction point.This circuit also can send the control signal of detonating charge.
This method only is used to set up the insulation strip on the bottom fire approach that hangs down earthquake intensity.This method is used to limit to prairie fire and the bushes fire is the most effective.At this moment fire is only limited to, rather than is pressed, and more is not extinguished.
Above-mentioned known method and realize the basic shortcoming of the device of this method is fuel-air cloud to take place before detonating charge detonates not have the possibility of control spontaneous combustion high.
The reason that causes this situation is particularly to have eventuality in the thermal drop and the windstream speed of zone of origin in fire zone, and this just hinders the formation of the fuel-air cloud of chemical equivalent composition, and is difficult to determine the functioning delay of detonating charge.
Under situation preferably, be to produce uncomplete explosion, and be the burning that fuel-air mixture takes place mostly, so just cause artificial fire, and caused fire to continue to strengthen.
In addition, when the successful blast of thin dispersion fuel-air cloud and formation air-shock wave, owing to not using extinguish material to make the effect of air-shock wave can not get the additional cooling of fire zone and the support of isolation.Therefore be accompanied by fire and promote fire spread and the process of diffusion (overheated, oven dry, pyrolysis) can not stop, thereby greatly reduce the effect of this method.
One of major defect that the restriction said method uses is that it can not be used for difficult arrival area and puts out large-scale fire.
The objective of the invention is to set up a kind of method and apparatus that limits to and/or stamp out a fire, effect when it changes thin disperse cloud and air-shock wave to combustion zone into by means of the fire extinguishing composition is instantaneous, and with high probability make fire extinguisher plant this zone in concerted action, by the fire scope extinguish material that farthest distributes, it can guarantee under the condition of tens of times of extinguish material surface density reductions the fire press belt to be enlarged manyfold, and can put out a fire and guarantee the safety of surrounding environment in unattainable area.
The method that achieves the above object is with the basis that act as of air-shock wave in limitation and/or the method that stamps out a fire, this shock wave is to produce by the fire extinguisher plant of band extending agent that is transported to fire zone and disperse dynamite container, described disperse dynamite container is ignited by control signal, according to the present invention, the extending agent of fire extinguisher plant uses extinguish material, select to transport the instrument of fire extinguisher plant in advance according to the characteristics of fire, the extinguish material kind of institute's filling, determine the section that needs fire extinguisher plant to start, transport instrument according to selected fire extinguisher plant then and determine parameter, when reaching specified value, this parameter guarantees the disperse explosive initiation by control signal, use the fire extinguisher plant of the sensor that is equipped with above-mentioned selected parameter, and with sensor adjustment to stipulating parameter value, when fire extinguisher plant just reaches the preassigned parameter value during near the above-mentioned predetermined segment of combustion zone, direct blast at fire zone generation disperse explosive, and form air-shock wave simultaneously, the fast ram pressure of air-explosion product, make extinguish material in this section fragmentation and form thin disperse cloud, and can be according to the extinguish material of fire kind and formation the scope and the position of the above-mentioned section of size Selection of thin disperse cloud.
So just guaranteed the commonality of fire extinguisher plant of the present invention and can under various fire condition, be extensive use of, for example forest fire, Urban Fires, made protected area avoid external fire, and the fire of fire and difficult arrival area on a large scale.And can reach following effect: extinguish material is transported to the fire zone free of losses, and extinguish material is evenly distributed on burning surface, and has additional fire extinguishing factor (overpressure, air-shock wave and fast ram pressure).
When putting out extensive fire; preferably use aircraft as the instrument that transports fire extinguisher plant; fire extinguisher plant is shed above the conflagration area that pre-determines and select according to the fire condition; and at this moment must select fire extinguisher plant to be positioned at height on the ground level as parameter; and use is equipped with the fire extinguisher plant of height sensor; described sensor is adjusted to the height of concerted action on the combustion zone ground level in advance according to the fire condition, the detonating of the control signal generation disperse explosive that sends by height sensor when fire extinguisher plant arrives this height.
Use aircraft to transport instrument and can guarantee that fire extinguisher plant arrives burning things which may cause a fire disaster with high probability, this point is very important to difficult arrival area on the geography, as the mountain ridge, and isolated area, virgin forest, matto, cross-country locality.This method can stamp out a fire in the place that explosion hazard, high temperature, the prestige fire fighter of association life are arranged.Can use simultaneously non-professionality aircraft and helicopter, military transportation airplane, and can by day or put out a fire night.
This method also is suitable for using ground instrument that fire extinguisher plant is transported to fire zone, it is arranged in approaches previously selected section before the fire forward, select temperature as parameter, at this moment fire extinguisher plant preferably is equipped with temperature sensor, and according to the fire condition it is adjusted to the temperature of concerted action in advance, detonating when the fire forward approaches the fire extinguisher plant present position by the control signal generation disperse explosive of temperature sensor.
Because air-shock wave and the cooling of extinguish material and the combined action of isolation effect have guaranteed reliably and promptly to limit to fire, and protected forest or area, grassland and be positioned at wherein valuable and/or dangerous target.
The also available following method of purpose of the present invention reaches, the fire extinguisher plant of implementing limitation and/or stamping out a fire has the container of band filler and disperse dynamite container, its explosive initiation device connects with the control signal circuit, according to the present invention, container is equipped with extinguish material as filler, and the control signal circuit is equipped with regulation to select the sensor of parameter, this sensor adjustment is to given parameter value, and electrically connect with the explosive initiation device, when fire extinguisher plant during near combustion zone above-mentioned parameter reach the given value of regulation, make the control signal that sends by sensor cause the self-cocking action of disperse explosive.

Fig. 4 is for by the circuit unit of control signal of the present invention and by the present invention, with them and the connecting of the firing device of disperse dynamite container.
Limitation of the present invention and/or the method that stamps out a fire are as follows.
Select the instrument that transports (Fig. 1) of fire extinguisher plant according to the characteristics of fire.In the accompanying drawings this to transport instrument be helicopter 2, its below, bottom is hanging the freight container 3 that has dozens of fire extinguisher plant 1.Filling is according to the extinguish material of fire condition and kind selection in the fire extinguisher plant 1.
Analytic combustion characteristics in advance, and the definite zone that need shed fire extinguisher plant 1 are drawn the figure in these zones.The servo-actuated parameter of the concerted action of fire extinguisher plant 1 is carried out in selection then.Paint in the scheme at Fig. 1, this parameter is for being positioned at position height above the ground level shedding the fire extinguisher plant 1 that falls above the combustion zone.In addition, can also to be fire extinguisher plant 1 shed to arriving this highly required time on this zone ground level by beginning this selection parameter.When shedding by freight container 3, the fire extinguisher plant 1 of height sensor is equipped with in use, according to the height of fire condition enactment concerted action above the combustion zone ground level, the control signal by height sensor when arriving this height produces detonating of disperse explosive to described sensor in advance.The result directly forms the thin disperse cloud 4 of extinguish material in fire zone, and forms the air-shock wave 5 with explosion product and air pressure head simultaneously.Can select fire extinguisher plant 1 the work scope and the position in zone according to the kind of fire and the size that forms this thin disperse cloud 4, fire extinguisher plant 1 usefulness that are placed on when using helicopter 2 in the freight container 3 can be fixed it by the lock pin of shedding signal release fire extinguisher plant 1.
Fig. 2 illustrates this method makes the protection object avoid another embodiment of external fire infringement, has used the ground of fire extinguisher plant 1 to transport instrument here, and fire extinguisher plant is put into predetermined fire forward presumptive area before.
In this scheme of implementing this method, basic purpose is that external fire (as forest fire or prairie fire) is avoided in the protection area.Often there are military target, resident villages and small towns, Forest Park, oil well, gasser and other civilian economy engineering items in the certain areas that are positioned at forest or grassland, and these areas prevent that the method for external fire is as follows.
At the high duration of risk of the probability of presence of fire (for example May～September at Russia middle part); along protected regional 7 periphery 6 (can only on adventurous direction) the high fire extinguisher plant 1 apart from ground 1.5～2m is set, its spacing equals the diameter of 1 fire extinguisher plant 1 sphere of action.Fire extinguisher plant 1 is equipped with temperature sensor 8 and for example is adjusted to temperature t=250～300 ℃.This value depends on the composition of protected regional internal combustion material.When fire the place ahead is approached to certain distance, make near fire extinguisher plant 1 temperature reach this value, just send control signal the disperse dynamite container is detonated.This kind method can be mended and be established circuit, is sent the concerted action signal of fire extinguisher plant 1 by this circuit by the operator.This programme is suitable for protecting the area (arsenal, military base, oil well, gasser and their warehouse) of standing valuable or risk object.
Stamp out a fire and form boundary belt around the area and also can and be attended by air and the forward of the air-shock wave of the fast ram pressure of explosion product 5 carries out by means of the combined action of the thin disperse cloud 4 of extinguish material.
The fire extinguisher plant 1 that introduce to propose below and be used to put out the working example of forest fire.
Putting out forest fire remote or unattainable area; and put out when the area of woods of catching fire reaches hundreds of square kilometres extensive fire and preferably use aircraft to transport fire extinguisher plant 1; as shown in Figure 1; above-mentioned fire extinguisher plant 1 is placed in the delivery container 3 that helicopter 2 hangs below, is transported to fire zone.When putting out forest fire, importantly prevent its forward and make it not extend to other areas, just make the fire localization.Fire extinguisher plant 1 is shed along the fire forward for this reason, the time gap of shedding depends on the speed of helicopter 2 and the sphere of action scope of 1 fire extinguisher plant 1, for example, when helicopter speed is that the effect dispersive region diameter of 55m/s (about 200km/h) and 1 fire extinguisher plant is when being 15m, shedding time gap is 0.27S, and when helicopter speed be that 42m/s (about 150km/h) sheds during with identical dispersive region diameter and is spaced apart 0.36S.
The formation that fire extinguisher plant 1 (Fig. 3) is made container, it has the housing 10 of band cylinder side wall, and wherein the filling extinguish material 11, for example silica-based water and minerals suspending fluid.
In addition, can use various special powder, solution and water as extinguish material.
Container can be made with the ecological material of going up cleaning (for example through the waterproof dip treating or be coated with the crash-resistant pressed paper of water-reducible finish).
This material falls back decomposition rapidly in the environment around.
The top of housing 10 connects with the stabiliser 13 with side otch 14 by adaptor union 12, and these stabiliser 13 usefulness pressed papers are made.Disperse dynamite container 15 is columniform liquefaction dynamite container, places container cylindrical shell 10 diad places.
The control signal circuit is placed in the sealed box 16,17, and one of them box is positioned at disperse dynamite container 15 following container bottoms, and for sensor usefulness, and another box is positioned near the firing device 18 on disperse dynamite container 15 sides on the top of container.Box 16,17 usefulness electric wires 19 connect.
In seal box 16, place height sensor 22 (Fig. 4) and contact pickup 23.The input end that sensor 22 and 23 control signal output ends and control signal are converted to the assembly 24 of carrying out signal of detonating connects.Transition components 24 is pressed widely used insurance-executive circuit manufacturing in the explosion technique, can prevent the control signal that any concerted action element detonates to form.
Can use the radiotelex sensor as height sensor, this sensor is pressed the manufacturing of known circuit principle, for example by amplitude and the comparator circuit of threshold value and the control signal that highly sends in the given concerted action of distance ground 2～5m scope internal fixation of the Doppler signal of ground return, the reliability of this height sensor under high disturbance rejection condition is 0.95～0.98.
When fire extinguisher plant 1 carries out concerted action by other selected parameters (Fig. 2), but serviceability temperature sensor 8 as parameter sensors, and the cancellation contact pickup 23, other parts of circuit diagram are identical with Fig. 4.
The mode of operation of fire extinguisher plant 1 (Fig. 1) is as follows.Send the concerted action signal of lock pin in the delivery container 3 according to the instruction of the operator in the helicopter cabin.After lock pin generation concerted action, fire extinguisher plant 1 is dished out, and strains braided wire 20 (Fig. 3) under the effect of whereabouts gravity, and pulls out contact ball 21 along the guide rail of freight container 3.Remove first order insurance simultaneously, and make sensor 22,23 (Fig. 4) energized.Through 3 seconds, leave helicopter and fall to after the safety distance after fire extinguisher plant 1 is dished out, remove second stage insurance, height sensor 22 (Fig. 4) is started working, and measures to ground-surface distance always.The signal of height sensor 22 is sent to the input end of converter assembly 24 when arriving assigned altitute, forms and send the execution signal of firing device 18 concerted actions, ignites disperse dynamite container 15 subsequently.When height sensor 22 et out of orders, send the execution signal when contacting to earth once more by contact pickup 23.
Blast wave that forms and explosion product make that pressure increases hundreds thousand of times in fire extinguisher plant 1 (Fig. 1) volume, and make housing 10 (Fig. 3) fragmentation, and shed extinguish material 11.Extinguish material 11 is tens of microns a droplet by fragmentation in motion process, has so just increased the interactive surfaces of extinguish material and incendiary material, has improved its result of use.The expansion of explosion product causes the formation (Fig. 1) of air-shock wave, and it moved with ultrasonic velocity before disperse fire extinguishing cloud 6.Fire-fighting principle is the effect to burning things which may cause a fire disaster time of air-shock wave, fast ram pressure and extinguish material.Preceding two factors are pulverized flame and are removed incendiary material, and extinguish material then cools off burning things which may cause a fire disaster and isolates incendiary material, thereby stop ambient medium pyrolysis and overheated.
The present invention can be used for the regional strong fire that puts out on a large scale and have explosion hazard and the continuous intensification of burning of difficult arrival effectively.
Use the extinguishing method and the device that propose can reduce tens of times of extinguish material surface densities, and reduce the wastage in bulk or weight of putting out and limiting to fire.Free of losses when transporting extinguish material to combustion zone, extinguish material is evenly distributed at burning surface, and the combined action of the thin disperse cloud of extinguish material, air-shock wave residual pressure and fast ram pressure all makes uses effect of the present invention to be better than known in the past method greatly.Experiment is determined, for the surface density of putting out the required fire extinguishing solutions of forest fire is 0.120～0.150Kg/m
2, and use spraying to need water 12～15kg/m
2When the volume of fire extinguisher plant 1 is for example 0.04m
3The time, the radius that puts out forest fire is 7～8m, like this, just can set up the fire extinguishing band of width 15～20m and length 600～800m when once loading 42 fire extinguisher plants.
One of preferential key factor of using of decision the present invention is its commonality; it both can also use under the condition in the open air in the city; avoid strong fire as the protection zone; put out forest and prairie fire; can use deprofessionalization aircraft, military transportation airplane and helicopter to transport, can also put out a fire round the clock.
