Description
Technical Field
The invention relates to the technical field of fire fighting, in particular to a pipe-belt type fire extinguisher and a fire extinguishing method.
Background
At present, the main method for fighting the forest fire is to shoot the fire directly by cutting fresh branches and binding them into broom or binding them on a wooden stick with wet hemp bags. The second is a covering soil fire-extinguishing method, which mainly uses a shovel to shovel soil to extinguish fire. Thirdly, the wind fire-extinguishing method utilizes a wind fire extinguisher to directly extinguish fire. Fourthly, the isolation zone method is used for cutting trees off in order to protect the large forest and select favorable conditions such as rivers, roads, wet hollow lands in the forest and the like. The width is generally more than twice the height of the tree, and all combustible materials are removed in the isolation belt. However, these methods require direct access to the fire, which makes fire fighting difficult and causes loss of the fire fighters during the process of fighting the fire.
Disclosure of Invention
Aiming at the current situations that fire is difficult to extinguish and fire personnel are injured and killed when fire fighting is carried out in large-area areas such as forests, mountains and the like, the invention discloses a pipe-belt type fire extinguisher which can extinguish mountain fire in a remote throwing mode without personnel entering a fire scene, and adopts the technical scheme that:
the utility model provides a pipe belt fire extinguishing apparatus, includes the first pipe area that both ends are sealed, length is not limited, first pipe in-band cover is established rather than length proximity, both ends confined second pipe area, fill the explosive in the cavity in second pipe area and bury more than one ignition underground, the second pipe area with the cavity between the first pipe area is filled dry powder extinguishing agent.
Compared with the prior art, the explosion-proof explosive breaks through the tradition, when the explosive tube is exploded, a large strip-shaped area filled with carbon dioxide can be formed to isolate oxygen, so that mountain fire is immediately extinguished without burning, meanwhile, the explosion enables the dry powder extinguishing agent to form a large strip-shaped atomized powder flow, the atomized powder flow is emitted to flame, sodium bicarbonate in the dry powder is decomposed under the action of high temperature, the reaction is endothermic, a large amount of carbon dioxide and water are released by the reaction, and the water is heated to be changed into water vapor and absorb a large amount of heat, so that the effects of cooling and diluting combustible gas are achieved; after the dry powder enters the flame, the heat radiation of the flame is reduced due to the absorption and scattering effects of the dry powder, and the spread of the fire to adjacent trees is reduced. The blasting agent and the fire extinguishing agent supplement each other and act synergistically to achieve the fire extinguishing effect that one plus one is far more than two.
Further, the first pipe belt and/or the second pipe belt are flexible, waterproof and airtight flame-retardant pipe belts, thick-walled pipe belts made of organic polymer materials added with flame retardants or composite pipe belts formed by at least a waterproof layer, a braided fabric reinforcing layer and a heat-insulating flame-retardant layer.
Furthermore, the explosive is a high explosive in powder or slurry state, the detonation velocity is more than 5000 meters per second, and the explosive cannot be directly detonated by open fire and a fire rope.
Further, the detonation device comprises a digital electronic detonator, and the digital electronic detonator can be detonated by a remote detonation controller.
Furthermore, the dry powder extinguishing agent is an ultrafine dry powder extinguishing agent. The superfine powder has large specific surface area, high activity, high decomposition speed under heating, high free radical trapping capacity and high fire extinguishing efficiency, and forms stable aerosol suspended in air. The literature is documented as follows: british KIDD company develops a potassium bicarbonate superfine dry powder extinguishing agent with the particle size of less than 5 mu m, and the full-submerged extinguishing experiment shows that: the fire extinguishing efficiency is 10 times of that of the common fire extinguishing agent. Zhang Wei et al successfully prepare the ultrafine ammonium phosphate dry powder extinguishing agent with the particle size of 100-500 nm by adopting a water phase synthesis method, taking ammonium dihydrogen phosphate as a main material and adding talcum powder, mica powder, activated clay, silicone oil, white carbon black, sodium silicate and other auxiliary materials. The dry powder extinguishing agent has low price and good extinguishing effect, and can generate great economic benefit and social benefit.
The invention also discloses a fire extinguishing method of the pipe belt type fire extinguishing apparatus, and the first method is that in a critical area of fire, a plurality of pipe belt type fire extinguishing apparatuses are arranged end to end in an intersecting way, and the fire is suppressed by simultaneously and remotely detonating through a detonating controller.
The other method is that an airplane or an unmanned aerial vehicle is used for flying to the upper air of a fire scene, the pipe belt type fire extinguishing devices are airdropped to a fire area one by one, and after falling to the ground, the pipe belt type fire extinguishing devices are remotely detonated one by one through the detonation controller to extinguish the mountain fire.
The pipe belt type fire extinguishing apparatus can be thrown to a fire area one by using a thrower, and after the pipe belt type fire extinguishing apparatus falls to the ground, the pipe belt type fire extinguishing apparatus is detonated remotely one by the detonation controller to extinguish the mountain fire.

Detailed Description
The utility model provides a pipe belt fire extinguishing apparatus, includes length 20 m's first pipe area 1, first pipe area 1 is from outer to interior compound pipe area that includes thermal-insulated fire-retardant layer, waterproof layer, knitting enhancement layer inlayer barrier layer formation in proper order, paints sealed glue behind the both ends binding port, then seals through steel wire clamp chucking. The second pipe belt 2 with the diameter of 19.8m is sleeved in the first pipe belt 1, the second pipe belt 1 is a thick-wall pipe made of organic high polymer materials added with flame retardants, and two ends of the thick-wall pipe are sealed through hot melting. The cavity of the second pipe belt 2 is filled with TNT powder explosives 3, two ends of the second pipe belt are respectively embedded with an ignition device 4, the ignition devices 4 are digital electronic detonators which are connected in series and can be simultaneously ignited by a remote ignition controller, the cavity between the second pipe belt 2 and the first pipe belt 1 is filled with an ultrafine dry powder extinguishing agent 5 which mainly comprises an active fire extinguishing component, a hydrophobic component and an inert filler, the hydrophobic component mainly comprises silicone oil and hydrophobic white carbon black, the inert filler is various in types, and the functions of preventing compaction and agglomeration, improving the motion performance of dry powder, catalyzing the polymerization of the dry powder silicone oil, improving the capacity of the dry powder extinguishing agent and the like are achieved.
