Description
Technical Field
The invention relates to an intelligent forest fire extinguishing system, and belongs to the technical field of forest fire extinguishment.
Background
In the field of forest and grassland fire extinguishment, a method for extinguishing forest fires is taken as an example:
The method for putting out forest fire includes manual putting out, soil fire extinguishing, water fire extinguishing, gas fire extinguishing, fire extinguishing with fire, fire prevention line opening to prevent fire spreading, artificial rainfall, wind fire extinguishing, chemical fire extinguishing, explosion fire extinguishing, aviation fire extinguishing and the like.
The fire extinguishing equipment is mainly provided with a tool for extinguishing open fire, afterfire and starting fire line. Including wind-powered fire extinguisher, hand-thrown fire extinguishing bullet, small water pump, water gun, forest fire sprinkler, hacking knife, shovel, hoe and brush cutter, chain saw, axe, hoe, etc.
The fire extinguishing mode is a direct fire extinguishing method, and fire extinguishing machines are used for directly intersecting fire to stop burning. This method is generally suitable for weak and moderate surface fires (people can get close to extinguishing fires), and is not suitable for strong fire or crown fires. The direct fire extinguishing method adopts a plurality of machines and tools, and can use mechanical fire extinguishing tools, chemical fire extinguishing agents, water and soil. The second is indirect fire extinguishing method, which mainly establishes fireproof isolation belts, such as fire line opening, fireproof ditch digging, fire attack by fire, etc. It is mainly suitable for strong burning surface fire, crown fire and underground fire which is difficult to extinguish.
According to the occurrence rule and fire extinguishing characteristics of forest fires, the forest fires must be extinguished in stages according to the procedure of controlling and then extinguishing and then consolidating.
However, the existing fire extinguishing technology and fire extinguishing equipment have limited corresponding effects, almost mainly comprise forest fire fighting sprinkler cars, but have the defects of large water consumption and low fire extinguishing efficiency; in particular, the adhesion of water on the surface of the combustion object is very large, a large amount of water is vaporized and evaporated, and the fire extinguishing effect is not obviously exerted.
If the unmanned plane is used for remotely throwing the fire extinguishing bomb to extinguish the fire, firstly, if the fire extinguishing medium (such as dry powder, fire extinguishing liquid and the like) in the fire extinguishing bomb has a general fire extinguishing effect, if the fire extinguishing bomb is exploded by utilizing the impact force generated by high-altitude throwing, the explosion radius of the fire extinguishing bomb is limited, and the fire extinguishing area is limited; in the case of fire extinguishing fluids, the current commercially available fire extinguishing fluids (e.g., foam extinguishing agents) have the difficulty of generating a large amount of foam during remote control. If the foam extinguishing agent with high multiple is prepared in advance, the unmanned aerial vehicle cannot be used for mass transportation; if concentrate the stoste to inside the fire extinguishing bomb, then utilize the mode of follow-up watering to make the foam, the technical difficulty is very big, because there is not stirring foaming process, the foaming volume is very little, and the fire extinguishing effect is limited. If the foaming agent is arranged on the unmanned aerial vehicle, foam generated by the foaming agent on the unmanned aerial vehicle is introduced into a fire scene through a pipeline, the effect of the method is limited, the problem of a water source cannot be solved, meanwhile, the problem of how to accurately adopt foam covering operation to the fire scene is difficult, and the accurate foam paving operation cannot be performed because of strong smoke in the fire scene.
Based on this, the present invention has been proposed.

Further, the cover layer 12 is made of benzoxazine resin, the medicine storage tank 13 is made of polyarylsulfone, and the spherical shell 100 is made of aluminum alloy.
Wherein, the spring 17 is provided with three, and the embedded thermosensitive initiating mechanism is provided with six groups.
The binding nail is provided with four sharp claws, one of the four sharp claws is thrown, the other sharp claw is propped against the ground, and the other sharp claw is upright; the upper tip is pushed down, and the lower tip is raised again; always, there is always one tip vertically upwards, and three tips are symmetrically supported on the ground.
Therefore, after the fire extinguishing bomb is thrown from the high altitude, three supporting feet 20 are always supported on the ground, and the fourth supporting foot 20 is vertically upwards.
Due to the arrangement of the conical heads 24, the conical heads 24 of the three supporting legs 20 below are easy to prick into the soil, and on one hand, the projectile body 10 can be separated from the ground for a certain distance, so that the subsequent explosion is convenient; on the other hand, when the supporting leg 20 explodes, it generates more earth, thereby covering the combustibles within the explosion radius, isolating the air, and achieving the purpose of extinguishing fire.
The ignition point 341 ℃ of the general polyethylene is lower, and the polyethylene is easy to ignite in a general fire scene, so that the peak boss IV 222, the loop pipe IV 223, the loop pipe V224, the loop pipe VI 225, the peak boss V226 and the like can be burnt and broken firstly, the magnesium particles filled in the polyethylene are ignited, and when the magnesium particles which are severely burnt are burnt, the polyether-ether-ketone film on the inner barrel 2211 can be burnt and broken; the polyether-ether-ketone has higher glass transition temperature 143 ℃ and melting point 343 ℃, the load thermal deformation temperature is up to 316 ℃, the instantaneous use temperature can be up to 300 ℃, and the polyether-ether-ketone has self-extinguishing property, and can reach the 94V-0 grade of UL standard even if no flame retardant is added. Therefore, only the high temperature generated by the severe combustion of magnesium particles can easily break them. When polyethylene burns at a constant speed, the polyethylene can be burnt for a period of time, and the polyethylene is equivalent to the protection of thermite in the polyethylene, so that the polyethylene can only be broken from a magnesium particle burning place, then the thermite in the outer cylinder 2210 is ignited to generate thermite reaction, and severe combustion is performed to cause explosion, so that the shell-and-tube heat-sensitive detonating mechanism 22 is exploded, and the metal tube 21 is exploded along with the thermite; on one hand, the thermite is used very little, the total amount of the thermite is less than 1% of the gel type fire extinguishing liquid, and the thermite is mainly used for preventing excessive consumption from aggravating the combustion degree nearby; in addition, the use amount is small, so that the heat-sensitive primer can be conveniently stored in the raised structures of the shell-and-tube heat-sensitive primer mechanism 22; it should be noted that, because of the installation position of the thermite, the structures of the crest convex portion 212, the collar portion 213, the taper pipe portion 214, the three crest convex portions 216, the taper pipe portion 218, the collar portion 219 and the like must be provided, so that the shell-and-tube type thermosensitive initiating mechanism 22 can generate larger downward thrust when detonating, thereby frying larger pits, and the earth covering radius generated by explosion is larger.
Since a part of the explosive force generated when the three supporting legs 20 incline pushes the projectile body 10 upward, and the downward pushing force generated when the fourth supporting legs 20 explode can mostly act on the projectile body 10, the projectile body 10 is restrained and prevented from being exploded too high.
The aluminothermic reaction time is short, and on one hand, under the coverage of the covering soil, the aluminothermic reaction can be extinguished quickly; secondly, under the coverage of gel formula fire extinguishing fluid, can improve the effect of coverage, cooperate the forest fire control watering lorry to carry out many rounds of watering to the region of taking place the conflagration and put out a fire, can cover earth, hydrogel or water film etc. on the burning thing surface, the adhesive force is strong to effectively prevent that the burning thing from re-burning. Even if a trace amount of scattered aluminothermic reaction products are not covered and extinguished by soil at first, the extinguishing bomb must have open fire to be burnt in an explosion way, which means that even if a small amount of new fire is generated in the fire scene, the whole fire scene is not greatly influenced. The main function of the fire extinguishing bomb is to prevent the re-combustion of nearby combustion products.
The application range of the invention is as follows: when a fire disaster occurs in forests and grasslands, the unmanned aerial vehicle is controlled to mount the fire extinguishing bomb, and the fire disaster is controlled by the double isolation of the combustibles through the earth covering by explosion and the release of gel-type fire extinguishing liquid, so that the spread and development of the fire disaster are prevented. By adopting a mode of mounting the fire extinguishing bomb by an unmanned plane, combining explosion earthing and gel type fire extinguishing liquid to synergistically improve the adhesive force of attachments on the surface of a combustion object, and the afterburning can be effectively prevented; the fire extinguishing technology solves the technical problem of difficult fire extinguishment caused by complex terrain in forest and grassland fires, has the advantages of high-efficiency fire extinguishment, convenient implementation and the like, also avoids the problem of secondary disasters caused by explosion fire extinguishment, and achieves the purposes of reducing water consumption and improving fire extinguishing efficiency.
Similarly, for the elastomer 10, since the cover layer 12 is made of benzoxazine resin, the burning difficulty is greater than that of polyethylene, so that the first explosion occurs at the three supporting legs 20, which results in loosening of the soil in the explosion radius, and then the elastomer 10 explodes again, thereby enabling the creation of larger and deeper pits, and improving the explosion covering effect. The medicine storage tank 13 is made of polyarylsulfone, and after the magnesium strip 15 is ignited, the thermite is ignited to generate a severe thermite reaction. Usually, 1-2 embedded thermosensitive detonating mechanisms can be ignited for detonating, so that the quantity of thermite is strictly controlled, and the thermite reaction scale is limited.
The detonation method mainly depends on the high heat generated by aluminothermic reaction to cause the explosion of the closed cavity, and the radius of the earthing and the earthing quantity generated by explosion are improved to the greatest extent by the method of detonating the supporting feet 20 and then detonating the projectile body 10. Because the detonation and the like do not need any delay fuze, the effect of successive detonation is achieved by only depending on the open fire of a fire scene, and the explosion structure and the detonation structure are simple. Because of the complicated explosion structure and the delayed detonation structure, the high-speed falling is easy to fail, so that the detonation is impossible. The present invention can detonate even if the supporting legs 20 and the elastic body 10 burst due to the high drop, but the covered soil radius and the covered soil amount become small.
The arrangement of the lead ball 16 and the spring 17 ensures that the lead ball 16 continuously vibrates up and down in the projectile body 10 due to inertia after the fire extinguishing bullet falls down, which is beneficial to the supporting feet 20 being pricked into deeper soil layers in the initial stage, thereby effectively increasing the follow-up earthing radius and the earthing quantity.

JT1080 type super absorbent resin starch acrylate polymer of New materials limited in Junta in Buddha, the water absorption rate of the starch acrylate polymer can reach 730g/g. Therefore, the gel-type fire-extinguishing liquid containing the powdery acrylate polymer can be diluted by a large amount of water to obtain the diluted fire-extinguishing liquid, and the diluted fire-extinguishing liquid can still have a good fire-extinguishing effect. Taking 166.2g of gel-type fire extinguishing liquid as an example, diluting the gel-type fire extinguishing liquid with water by 35 times (adding 5817g of water), pouring the diluted fire extinguishing liquid into a watering pot to spray and extinguish fire on fully combusted wood blocks (the length is 30cm, the width is 10cm and the thickness is 2 cm), stopping spraying after the fire is extinguished, and spraying again after re-combustion until no re-combustion occurs.

Test method of fire extinguishing area and earthing radius
The unmanned aerial vehicle is utilized for high-altitude shooting, and then an image algorithm (such as a labeling algorithm based on binary image area segmentation and area calculation) is utilized to calculate the fire extinguishing area; the soil layer area covered by the surface of the combustion object is an effective covering soil area, namely the combustion object is completely covered, and a fire light cannot be seen during shooting. x=the explosion radius of the long diameter of the covering soil/2 times, and the long diameter of the covering soil is the maximum value between two points of the extreme edge of the soil layer covered by the surface of the combustion object; y=effective earth coverage area/explosion-affected area, which is a circular area with a radius equal to the explosion radius; λ=y/x, λ is the uniformity of the covering soil, and λ=1 is the most ideal state, the effective covering soil area can reach the maximum, and the covered soil layer is very uniform; because the soil layer covered by the surface of the combustion object is a very irregular circle, the outer edges are extremely unevenly distributed and are in spoke shapes, and larger gaps exist between adjacent spokes, if the effective soil covering area is required to be larger, the soil layer covered by the area close to the explosion center cannot be too thick, and more soil can be covered by the edge part, so that the gaps of the edge part are filled to the greatest extent.

Group B4: the magnesium particles/strips and thermite are replaced by TNT explosive, and if TNT explosive with the same mass is adopted, the TNT explosive has high power, and finally lambda=0.11 is measured. If the amount of TNT explosive is reduced until λ=0.53, the effective coverage area is reduced by 72% compared to that in group B1. This is because the TNT explosive of the present invention has high power, and the earth produced by explosion is very easy to splash and has high dispersion, which is not suitable for extinguishing a fire.
Group B5: the gel fire extinguishing liquid and tadpole-shaped glass tear drop are mixed according to the mass ratio of 1000:z, the z value is changed, the final lambda is measured, the graph is shown in figure 6, and the z is preferably 2.2; however, because the mass of the tadpole-shaped glass tear drops is different from one another to some extent, the use requirement can be met as long as the gel-type fire extinguishing liquid and the tadpole-shaped glass tear drops are met according to the mass ratio of 1000 (2.1-2.3).
At the moment of intense impact of the fire extinguishing bomb falling to the ground, a small amount of tadpole-shaped glass tear drops are exploded into particles and powder; during secondary explosion, a large amount of tadpole-shaped glass tear drops are exploded into particles and powder, and the gel-type fire extinguishing liquid can be distributed uniformly during splashing due to the dual effects, so that the earthing uniformity is effectively improved.
Group C1: if the metal tube 21 and the shell-and-tube type thermosensitive initiating mechanism 22 are all round tubes, the surfaces of the round tubes are provided with a plurality of round hollow convex rings, the hollow convex rings are filled with initiating explosive such as thermite, and the like, after the fence is internally exploded, fragments are collected, and the area is smaller than or equal to 2cm 2 The number of fragments exceeds 71.
Gold according to the inventionThe secondary tube 21 and the shell-and-tube heat sensitive primer 22 themselves have a "spring" like function, with a much better cushioning effect than the group C1. The metal tube 21 and the shell-and-tube thermal initiator 22 need to be burst to produce a burst vent that is ideally a tear vent, rather than bursting the metal tube 21 and the shell-and-tube thermal initiator 22 into a large number of tiny fragments, which meets the safety guidelines. After the metal tube 21, the shell-and-tube type thermosensitive initiating mechanism 22 and the elastomer 10 of the invention are exploded in the fence, fragments are collected, and the area is smaller than or equal to 2cm 2 Not exceeding 7.
Group C2: if the peak values of the two protruding parts 216 of the three peaks are equal, the rest are the same, the effective covering area of the obtained fire extinguishing bomb is reduced by 61% compared with the fire extinguishing bomb provided by the invention when the fire extinguishing bomb is finally exploded, and the area of the fragments after explosion is less than or equal to 2cm 2 Not more than 9 fragments.
Group C3: if the wave crest values of the five 226 wave crest convex parts are equal, the rest are the same, the effective earth coverage area of the obtained fire extinguishing bomb is reduced by 13% compared with the fire extinguishing bomb provided by the invention when the fire extinguishing bomb is finally exploded, and the area of the fragments after explosion is less than or equal to 2cm 2 The number of fragments exceeds 21.
Group C4: if the wave crest installation structures of the first wave crest convex part 212, the second wave crest convex part 216, the third wave crest convex part 2110, the fourth wave crest convex part 222 and the fifth wave crest convex part 226 are all circular ring structures, the rest are the same, and the obtained fire extinguishing bomb finally collects fragments when exploding, and the area is smaller than or equal to 2cm 2 The effective coverage area is increased by 2% compared with the fire extinguishing bomb according to the present invention by more than 49 fragments.
In the embodiment, the gel-type fire extinguishing liquid is dispersed on the surface of a combustion object along with the covering soil by the impact force of explosion, the gel-type fire extinguishing liquid can be further diluted by the water flow (usually only needs to be sprayed back and forth for 2-3 rounds of dilution), a layer of water film, a small amount of foam and a covering soil layer are finally formed on the surface of the combustion object, the surface of the combustion object is jointly sealed, the air is isolated, a three-phase heat insulation barrier (solid, liquid, gas or foam) is formed, the adhesive force is strong, choking effect is effectively generated on the combustion object, the continuation of combustion is prevented, the fire extinguishing effect is good, and the afterburning rate is low; can effectively extinguish the fire in forest, grassland and other forestry fields.
Conventional starch acrylate polymers are mixed with water and require a minimum of 3 minutes of agitation to form the fire suppressant. The fire extinguishing agent is uniformly sprayed on the solid combustion object, and can isolate air to extinguish fire although a covering film can be formed on the surface of the object; however, the fire extinguishing bomb cannot be filled with the fire extinguishing bomb, the fluidity is poor, even if the subsequent use of the water gun needs to continuously spray back and forth for 10 rounds (total 30 minutes) against the area covered by the fire extinguishing agent, no obvious dilution and diffusion of the fire extinguishing agent is found, only a part of the fire extinguishing agent is observed to be flung away by water flow, and the blocky trace is obvious, so that the fire extinguishing area is obviously limited; the fire extinguishing area is as follows: the fire extinguishing area of the fire extinguishing bomb filled with 1 kg of the fire extinguishing agent is at most 0.5 square meter.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
