Crash type fire-fighting grenade

Abstract

The invention relates to a crash type fire-fighting grenade. The crash type fire-fighting grenade comprises a grenade body and an ignition device, the ignition device is arranged at the top of the grenade body, a permanent magnet and a protruding type inner cavity are formed in the ignition device, a conductor rolling ball, an insurance pull ring and two electrode fixed contacts are arranged in the inner cavity, one ends of the two electrode fixed contacts are fixed to the ignition device, the other ends of the two electrode fixed contacts point to the center point of the inner cavity, and thegrenade body is provided with a main shell, an initiator and superfine dry powder. The crash type fire-fighting grenade is composed of the shell, the superfine dry powder, the insurance pull ring andthe contact type initiator. Insurance is opened during using, the insurance is violently threw to a fire source, compared with an existing product, the contact type initiator is adopted, so that thecrash type fire-fighting grenade is ignition while in contact; the superfine dry powder is adopted, relative volume and weight are reduced, and throwing is facilitated; and no fragment damage of a plastic shell exists.

Description

technical field [0001] The invention relates to a fire extinguishing equipment, in particular to a collision type fire extinguishing grenade. Background technique [0002] Most of the existing fire extinguishers are composed of high-pressure fire extinguisher tanks and rubber or plastic hoses. When extinguishing fires, manual or portable fire extinguishing gas tanks are required. Hand-held hoses are used to spray fire sources at close range. The operation is inconvenient and dangerous. If the distance is relatively short, firefighters will be exposed to the danger of sudden explosion and high-temperature air burning, and it is difficult to rush into the effective distance for fire extinguishing when the fire flame is large. [0003] The principle of the existing fire extinguishing grenade is the same as that of the military grenade. It needs to be opened for 5-10 seconds before the fire extinguishing agent is detonated and sprayed to extinguish the fire. Fire, after throwin...

[0002] Most of the existing fire extinguishers are composed of high-pressure fire extinguisher tanks and rubber or plastic hoses. When extinguishing fires, manual or portable fire extinguishing gas tanks are required. Hand-held hoses are used to spray fire sources at close range. The operation is inconvenient and dangerous. If the distance is relatively short, the firefighters will be exposed to the danger of sudden explosion and high-temperature air burning, and it is difficult to rush to the effective distance for fire extinguishing when the fire flame is large

[0003] The principle of the existing fire extinguishing grenade is the same as that of the military grenade. It needs to be opened for 5-10 seconds before the fire extinguishing agent is detonated and sprayed to extinguish the fire. Fire, after throwing a fire extinguishing grenade, it will roll to a long distance, so it cannot effectively deal with this kind of fire
