Description

Cut-explosion mixed reaction fire-fighting bomb for launching or throwing

Technical Field

The utility model relates to a fire control bullet especially relates to a fire control bullet is exploded to surely of transmission or throwing usefulness and is reacted in mixture belongs to fire-fighting equipment technical field.

Background

Fire emergency rescue often requires throwing or launching fire bombs from a long distance. The fire extinguishing principle of the fire-fighting bomb is that after the fire-fighting bomb is launched or thrown to a fire scene, the fire-fighting bomb is burst in a certain mode, and the sprayed fire-fighting material produces a fire extinguishing effect.

The existing fire-fighting bombs comprise the following components:

firstly, distinguishing according to the mode that fire extinguishing materials are sprayed after fire extinguishing bombs are thrown to a fire scene:

1. bursting fire-fighting bomb.

1.1 a small amount of blasting gunpowder (explosive body) is placed in the fire-fighting bomb, and the fire-fighting bomb is burst through the explosion of the gunpowder, so that the sprayed fire-fighting material has a fire-fighting effect.

The explosive body detonates the fire-fighting bomb, which can be divided into two kinds of fire-fighting bombs of electronic control detonation and gunpowder lead combustion control detonation.

An electronic control fire-fighting bomb is provided with an electronic trigger for triggering the explosion of the gunpowder. The mode is generally used on the large-scale fire control bullet that the cost is very high, is fit for the perpendicular mode of puting in.

The powder lead burns to control the explosion. The explosive body in the fire bomb is connected by the powder lead on the surface of the fire bomb. After the fire control bullet is thrown, the lead of the fire control bullet is ignited to detonate the fire control bullet when meeting fire, so that the purpose of fire extinguishing is achieved, and the mode is widely used at present.

1.2 impact or fire burst fire bombs, which are now in the early stages and are currently in less use. Is a fire-fighting projectile with the simplest structure. The basic principle is that the fire-fighting bomb is thrown, after the fire-fighting bomb reaches a fire scene, the brittle material bomb body is damaged by impacting an object or utilizing high-temperature combustion of the fire scene, and the fire-fighting material wrapped by the brittle material bomb body is sprayed and scattered, so that the fire-fighting effect is achieved.

2. Complicated structure and high cost

The series of structural designs of loading an explosive body in the fire-fighting bomb, placing an ignition electronic trigger or an ignition fuse and the like make the construction of the fire-fighting bomb complicated and increase the cost.

3. The fire extinguishing agent has single component

The fire extinguishing agents filled in the existing fire extinguishing bomb are single, one type is powder, and the other type is single fire extinguishing liquid. In order to improve the fire extinguishing effect, the method can fully exert a plurality of effective fire extinguishing materials to achieve better fire extinguishing effect through common reaction.
