Since the area of the pressing sheet 10 is larger than that of the window breaking striker 8, better force can be applied to the window breaking striker 8 when the soft shell 7 is deformed. More preferably, the elastic property of the soft body shell 7 gradually increases from inside to outside along the radial direction, and the elastic property of the contact part of the soft body shell 7 and one end of the window breaking firing pin 8 is the smallest, so that the soft body shell 7 can better apply force to the window breaking firing pin 8 when being deformed. The soft shell 7 may be made of a deformable material, such as plastic, rubber, etc.
As shown in fig. 1 to 4, the rear end of the fire extinguishing bomb body is fixedly provided with the tail wings 11, the number of the tail wings 11 can be 4-6, and the tail wings 11 can be made of plastic or glass fiber reinforced plastic composite material or metal material. The arrangement of the tail wing 11 is beneficial to ensuring that the window breaking fire extinguishing bomb keeps stable flight in the flight process.
The fire extinguishing powder 6 can adopt a physical fire extinguishing powder 6 or a chemical fire extinguishing powder 6, the physical fire extinguishing powder 6 falls outside the surface of a combustible substance by means of dry powder, chemical reaction occurs, and a layer of glass-shaped covering layer is formed under the action of high temperature, so that oxygen is isolated, and fire is extinguished by suffocation, the physical fire extinguishing powder 6 can be selected from powder materials such as mineral powder, fly ash and cement, and the physical fire extinguishing powder 6 achieves the fire extinguishing effect mainly in a mode of isolating air through physical covering. The chemical fire-extinguishing powder 6 is produced by means of chemical inhibition and negative catalysis of the volatile decomposition product of inorganic salt in dry powder and the free radical or active radical produced in the burning process to interrupt the burning chain reaction and extinguish fire. The chemical fire extinguishing powder 6 can be selected from, but not limited to, ammonium phosphate and other powder materials. It should be noted that the physical fire extinguishing powder 6 and the chemical fire extinguishing powder 6 are only relative concepts, and the possible fire extinguishing powder 6 has both chemical and physical fire extinguishing functions, such as an ultra-fine dry powder fire extinguishing agent, which has small particle size, good fluidity, good anti-flammability, dispersibility and electrical insulation, and the fire extinguishing mechanism is mainly chemical fire extinguishing, and the flame can be extinguished through the chemical and physical fire extinguishing functions. Preferably, the fire extinguishing powder 6 is an ultrafine dry powder fire extinguishing agent, and the ultrafine dry powder fire extinguishing agent is a solid powder fire extinguishing agent with 90% of particle size less than or equal to 20 microns. The superfine dry powder extinguishing agent is proved to be one of the extinguishing agents found at home and abroad, the extinguishing concentration is lowest, the extinguishing efficiency is highest and the extinguishing speed is highest. The unit volume fire extinguishing efficiency is 2-3 times of that of a Halon fire extinguishing agent, 6-10 times of that of a common dry powder fire extinguishing agent, more than 10 times of that of a heptafluoropropane fire extinguishing agent and 15 times of that of carbon dioxide. The ozone depletion potential value ODP of the atmosphere is zero, the greenhouse effect potential value GWP is zero, and the ozone depletion potential value GWP has no stimulation to human skin, no corrosion to a protective object, and no toxicity or harm. The residues after fire extinguishing are easy to clean, and people in a fire scene can not be poisoned or suffocated to die. Meanwhile, the storage period can reach 3 years, and frequent replacement and maintenance are not needed. In the embodiment, the gas energy of the pyrotechnic composition 5 and the superfine dry powder extinguishing agent are used for double extinguishment, so that the A-type, B-type and C-type fire disasters can be instantly extinguished in a long distance.
In a preferred embodiment, as shown in fig. 4, the fire extinguishing bomb further comprises a firing cable 12, one end of the firing cable 12 is connected with the pyrotechnic composition 5, the other end of the firing cable 12 extends to the outside of the fire extinguishing bomb body, a channel for passing the firing cable 12 is formed between the fire extinguishing bomb body and the soft shell 7, or a channel for passing the firing cable 12 is formed in the shell 4 of the fire extinguishing bomb body. It is specifically optional, wrap around protecting the paper on the fuse 12, protect the paper and can be dampproofing tinfoil adhesive tape, protect the paper and can rub the fuse 12 and draw the protection, prevent that the 12 fast burning of fuse, cross fire and dampproofing. The arrangement of the firing cable 12 can play a role of double insurance, and even if the window breaking firing pin 8 does not detonate the pyrotechnic composition 5, the field flame can detonate the fire extinguishing bomb body through the firing cable 12.
Specifically, optionally, the shell 4 and the central tube 3 are both paper containers, so that the materials are environment-friendly and no secondary damage to environmental pollution and objects or people is caused; especially with keeping apart the scene of a fire to the scene of fire, the rescue of personnel that are enclosed in the scene of a fire clearance scene of being trapped has the special effect, is the sharp ware of opening the life passageway in the scene of a fire, and the material that the product adopted is paper class to guarantee not to produce sharp-pointed piece or bold hard thing when covering fire extinguishing powder 6, do not basically have the injury to the human body, relatively safe, therefore fire fighter can closely fight a fire. It should be noted that, when the shell 4 and the central tube 3 are both paper containers, the selected physical fire extinguishing powder 6 or chemical fire extinguishing powder 6 cannot react with the paper containers.
To sum up, the utility model discloses a fire control is with broken window fire extinguishing bomb, the surperficial interval of blasting head 1 is equipped with a plurality of broken window cutter bodies 2, and the central line of adjacent broken window cutter body 2 is not on same straight line, means that a plurality of broken window cutter bodies 2 can follow a plurality of directions and break the window, compares the broken window fire extinguishing bomb among the prior art, the utility model discloses a fire control is with broken window fire extinguishing bomb is more nimble in the use, can realize the ability that gets into the high-rise fire scene from the broken window of outdoor a plurality of directions, and the fire extinguishing bomb body that self carried can carry out effective control to indoor condition of a fire, realizes the indoor purpose of putting out a fire of high-rise building.
