Embodiment 1

[0029] A forest and grassland fire extinguishing grenade, comprising an outer casing 2 and an explosive 1, the inside of the outer casing 2 is filled with fire extinguishing materials and heat-insulating and flame-retardant materials 3 sequentially from the inside to the outside, and the fire extinguishing materials include TNT5 and white phosphorus 4. The TNT5, white phosphorus 4, heat-insulating and flame-retardant material 3, and the outer casing 2 are all wrapped in a thin aluminum cylinder, and the TNT5 is placed in the center of the casing and communicated with the detonator 1.

[0030] Fire extinguishing principle: The main materials inside the fire extinguishing grenade from the inside to the outside: TNT5, white phosphorus 4, heat insulation and flame retardant material 3, outer shell 2; Composed of fuse 12 and safety buckle 13, one end of the detonator 11 is inserted into the TNT5, and the other end is connected to the fuse 12, the fuse 12 extends to the outside of th...

Embodiment 2

[0034] On the basis of Embodiment 1, the detonator 1 is made up of a detonator 11, a fuse 12 and a safety buckle 13, one end of the detonator 11 is inserted into the TNT5, and the other end is connected with a fuse 12, and the fuse 12 extends to Out of the outer shell 2, and buckled by a safety buckle 13, the fuse 12 includes but not limited to a crash fuse 12 and a time-delay fuse 12. Time-delay fuse 12 can be provided with fuse 12 combustion and detonation time exceeds the time of fire extinguishing grenade from throwing to the burning bottom layer, realizes burning at the bottom of the fire place, bottom impact.

Embodiment 3

[0036] On the basis of Embodiment 2, the outer casing 2 is made of soft, fragile, and non-harmful fiber material after explosion, such as thin aluminum, which is easy to manufacture and shape, and is not easy to cause casualties to firefighters after explosion.

Abstract

The invention discloses a forest grassland fire extinguishing grenade. The grenade comprises an outer shell and a detonator, wherein a fire extinguishing material and a heat insulation and flame retardant material sequentially fill the interior of the outer shell from inside to outside, the fire extinguishing material comprises TNT, white phosphorus, the TNT, the white phosphorus, the heat insulation and flame retardant material and the outer shell are wrapped in cylindrical thin aluminum, and the TNT is arranged in the center of the shell and communicates with the detonator. The fire extinguishing grenade solves, the problem that an existing fire extinguishing technology basically requires short-distance manual fire extinguishing by firefighters, and casualties are easily caused to the firefighters after the shell is exploded.

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. 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, so far, the existing fire extinguishing technologies are generally mainly traditional methods such as dry powder, water spray, high-pressure wind, and felling isolation belts. Basically, firefighters need to manually extinguish the fire at close range, and operate the fire extinguisher to eject the fire extinguishing material from the container. Spray to the fire area to exti...
