Fire-fighting grenade for forest and grassland and application of fire-fighting grenade

Abstract

The invention discloses a fire-fighting grenade for the forest and grassland. The fire-fighting grenade comprises an outer shell and a detonator, the interior of the outer shell is filled with a fire-fighting substance and a thermal-insulation flame-retardance material from inside to outside in sequence, and the fire-fighting substance is arranged in the center of the shell, communicated with thedetonator and prepared from, by weight, 0.01-20 kg of TNT and 0.1-100 kg of white phosphorus. According to the fire-fighting grenade, the TNT is ignited to be exploded by the detonator of the fire-fighting grenade, after the TNT is detonated, the white phosphorus can be jetted with extremely large explosive power to be scattered to grass and trees in a mist shape, the white phosphorus is scatteredfor spontaneous combustion, oxygen is consumed through combustion to achieve fire extinguishment, and the huge air impact wave caused by TNT explosion can also achieve a fire extinguishment function.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a forest and grassland fire extinguishing grenade and its application. Background technique [0002] Forest fires, especially large-scale forest fires, are considered to be one of the world's major natural disasters, which have the characteristics of wide occurrence, strong suddenness, and difficulty in fighting. Once this type of fire spreads, it will cause heavy casualties of humans and animals, huge property losses, and damage to the ecological environment. [0003] In terms of forest fire extinguishing, especially in the case of large-scale fires and large-scale fires, so far, the existing fire extinguishing technologies are mainly traditional methods such as dry powder, water spray, high-pressure wind and cutting isolation belts, which basically require firefighters to be close To extinguish the fire manually, operate the fire extinguisher to spray the f...

Once this type of fire spreads, it will cause heavy casualties to humans and animals, huge property losses, and damage to the ecological environment.

[0003] In terms of forest fire extinguishing, especially in the case of large-scale fires and large-scale fires, so far, the existing fire extinguishing technologies are mainly traditional methods such as dry powder, water spray, high-pressure wind and cutting isolation belts, which basically require firefighters to be close To extinguish the fire manually, operate the fire extinguisher to spray the fire extinguishing material from the container to the fire area to extinguish the fire. If the fire is fierce, the human body is too close to the danger; the conventional forest fire extinguishing method cannot achieve fast and efficient fire extinguishing due to the influence of terrain and other environments , easy to re-ignite; at the same time, the firefighters are labor-intensive when operating the fire extinguisher, and it is easy to cause casualties to the firefighters when manually extinguishing the fire at a close distance
