Compound long-distance extinguishing method and device for forest fire

Abstract

The invention discloses a compound long-distance extinguishing method and a device for forest fires. In the invention, a launching vehicle is used for carrying fire extinguishing bombs, and a command and control system sends out a command to launch the fire extinguishing bombs to a fire scene in a long distance mode, wherein the fire extinguishing bombs are provided with proximity fuses and / or impact fuses based on conditions of the fire scene, the proximity fuses have an explosion height of 3-5 m and are mainly used for crowning fire, and the impact fuses are mainly used for surface fire. Because the launching vehicle is used for carrying the fire extinguishing bombs, the fire extinguishing bombs are launched by means of the command and control system to the fire scene in a long distance mode, and the fire extinguishing bombs can be optionally provided with two different fuses (proximity fuses and impact fuses) to form an all-dimensional three-dimensional extinguishing mode, and therefore, the invention can effectively extinguish surface fire and crowning fire, control fire behavior in time and prevent the overspread of the fire. By adopting the long-distance launching mode, the invention reduces casualties; the fire extinguishing bombs are provided with impellers, thereby achieving long firing range; and warheads of the fire extinguishing bombs are filled with superfine dry powder high-efficiency extinguishing agent, thereby having good extinguishing effect.

Description

Technical field [0001] The invention relates to a fire extinguishing method and device, in particular to a compound remote fire extinguishing method and device for forest fires. Background technique [0002] The current forest fire fighting mainly relies on simple equipment such as fire extinguishers, portable water guns, and wind extinguishers used by ground fire extinguishers. Although these equipment are simple in structure and portable, they can only extinguish low-intensity surface fires and are low in efficiency. At the same time, the current fire extinguishing agents used for forest fire fighting are mainly water, sometimes supplemented by chemical additives or chemical fire extinguishing agents. The fire extinguishing effect of water has a great relationship with its state in the fire scene. If water is directly sprayed or sprinkled on the fire site, due to the uneven distribution of water, the water droplets are too large, and most of the water will not have the effect ...

AI Technical Summary

Problems solved by technology

Therefore, in view of the insufficient performance of existing fire extinguishing equipment, it is necessary to study a forest fire extinguishing equipment that can be projected remotely and has high fire extinguishing efficiency.
