Description
Technical Field
The invention relates to the technical field of emergency technical research, in particular to a reusable non-explosive fire extinguishing bomb and a fire extinguishing system.
Background
Forest fire extinguishing bomb is used as an emerging fire extinguishing means, and is gradually accepted by countries around the world due to the advantages of safety, high efficiency and the like, so that the forest fire extinguishing bomb becomes the main forest fire extinguishing equipment at present.
Fire types are different, and fire extinguishing modes and means are also different. The existing fire extinguishing modes can be divided into contact fire extinguishing and non-contact fire extinguishing, such as: the fire extinguisher is directly used for entering a fire scene to extinguish the fire, and the fire extinguishing device is thrown into the fire scene to extinguish the fire through long-distance projection to extinguish the fire. At present, most forest fire extinguishing bombs adopt military cannonball technology to release fire extinguishing agents, namely, gunpowder is filled in a bomb body, and the bomb is detonated after being launched to a fire scene, and the fire extinguishing agents are thrown into the fire scene to extinguish the fire. The fire extinguishing bomb can form spherical powder cloud after explosion, is influenced by airflow in a fire scene, and cannot be completely thrown to a fire source, so that the fire extinguishing bomb has low fire extinguishing efficiency, and meanwhile, the bomb body is a disposable consumable part and cannot meet the environmental protection and economic principles proposed by the current country.
The fire extinguishing bomb is mainly launched in two modes, namely a military mortar throwing mode and an aircraft-supported aerial throwing mode. The effective throwing distance of the throwing mode is smaller, the characteristic that the spreading speed of the forest fire scene is fast cannot be dealt with, and the safety cannot be guaranteed. The aerial throwing mode is limited by factors such as cost, system and the like, and an effective system cannot be formed;
meanwhile, most of the current fire extinguishing bombs adopt self-explosion type, although the fire extinguishing bombs have a certain fire extinguishing effect, the inside of the bomb body adopts a pipe explosion mode to explode, namely, a flame detonator and a pipe explosion are arranged in the bomb body, the flame pipe is utilized to explode explosive or black powder in the pipe explosion, so that the bomb body is exploded, and the fire extinguishing agent is scattered to a fire place to realize fire extinguishing, and the explosive or black powder has strong explosion impact force, so that the fire extinguishing bomb has double fire extinguishing effects of explosion shock waves and fire extinguishing agents. But has strong blasting capability and high potential danger and danger coefficient.
In view of the lack of fire retarding capabilities of dry powder and foam extinguishing bombs themselves, the extinguished combustibles will also be ignited again. Therefore, how to select the fire extinguishing agent of the fire extinguishing bomb and ensure even spraying becomes the key for solving the problem. The conventional dry powder extinguishing agent is affected by the airflow of a fire scene, so that the problem that the fire source cannot be effectively covered due to uneven spraying is solved, and the problem that the colloidal foam extinguishing agent is precipitated due to water insoluble matters is difficult to generate enough colloidal substances and gas required by foam generation, so that the extinguishing capability is poor.
