Description

A kind of fire-extinguishing mine for fire extinguishing shrapnel

Technical field

The utility model relates to a kind of fire-extinguishing mine for fire extinguishing shrapnel, belongs to civilian fire extinguisher bomb field.

Background technology

The tradition fire extinguishing, at present on the pattern of putting out a fire to save life and property, still generally adopting by single manpower fire extinguishing, manpower fire extinguishing is main with mechanization fire extinguishing, the fire extinguishing shell for mortar mode of combining, fire extinguishing shell for mortar commonly used on the market, the general monoblock type that adopts fills the extinguishing chemical mode more, yet there is following shortcoming in the fire extinguisher bomb of this structure:

At first, the fire-fighting area of monoblock type single-shot fire extinguisher bomb is less, and be bullet and land trigger-type, can only be to ground fire effect, but forest fire and miscellaneous cause are very different, and flame will be altered and be burnt the above height of 10m, and center intensity of a fire temperature can reach degree more than 1000, be aloft to burn after particularly trees catch fire in the forest, it is not obvious to the treatment effect of forest fire that present integral body is landed the trigger-type fire extinguisher bomb.

Secondly, such fire extinguisher bomb does not possess self-destroying function, because special circumstances fail to do the time spent, the people and animals around the pick-up point is caused potential safety hazard when fire extinguisher bomb.

Global warming in recent years, forest fire has the trend of obvious rising, and the forest extinguishing situation is sternly pretty, has a great responsibility, and accounts for to be of great significance in national economy; Therefore develop the civilian fire extinguisher bomb that is applicable to the forest fire environment and seem more urgent.

The utility model content

The purpose of this utility model is to land the trigger-type fire extinguisher bomb in order to solve tradition, and fire-fighting area is less, and bullet lands the fire-fighting mode that triggers and can not satisfy the problem of forest fire needs, and a kind of fire-extinguishing mine for fire extinguishing shrapnel is provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of fire-extinguishing mine for fire extinguishing shrapnel of the present utility model comprises drag parachute, umbrella cover, umbrella rope, fire-extinguishing mine housing, extinguishing chemical, temperature-sensitive contact fuze;

Fill extinguishing chemical in the fire-extinguishing mine housing, the lower end of the fire-extinguishing mine housing temperature-sensitive contact fuze that is threaded, make temperature-sensitive contact fuze head-end ignition device be positioned at the fire-extinguishing mine enclosure interior and contact with extinguishing chemical, the heat-sensitive line of temperature-sensitive contact fuze rear end exposes outside the fire-extinguishing mine housing; Fire-extinguishing mine housing upper end processing umbrella Connection Block, the umbrella Connection Block links to each other with drag parachute by the umbrella rope, and the drag parachute overcoat has the umbrella cover, and fire-extinguishing mine is placed in the fire-extinguishing mine cabin body of fire extinguishing shrapnel.

The umbrella cover of each fire-extinguishing mine and the fire-extinguishing mine rear end of front end are fixed, and the umbrella cover of fire-extinguishing mine and front end blast cap are fixed foremost.

Extinguishing chemical adopts the super powder extinguishing agent of carbon dioxide.

Fire-extinguishing mine housing lower end also is connected with the time-delay self-destruction-type fuze, and this time-delay self-destruction-type fuze is connected with self-destruction control circuit wire on the big gun, forms fire-extinguishing mine time-delay self-destruction-type fuze bookbinding circuit.

The course of work

During the emission fire extinguishing shrapnel, the self-destruction control circuit is at first to the bookbinding of delaying time of the self-destruction-type fuze of each fire-extinguishing mine in the body of fire-extinguishing mine cabin on the big gun, after the time-delay of the buster fuse of body rear end, fire-extinguishing mine cabin reaches the scheduled time, start the buster igniter, and then the impelling medicine box that ignites, under the gas-flow effect, fire-extinguishing mine is dished out in the body of fire-extinguishing mine cabin successively, the umbrella of fire-extinguishing mine covers on lower being extracted of blast cap traction stretching foremost, its drag parachute is opened, this fire-extinguishing mine is extracted the umbrella cover of a rear fire-extinguishing mine again, and its drag parachute is opened, and then finishes the parachute-opening of dishing out of all fire-extinguishing mines; Fire-extinguishing mine under the effect of drag parachute, fall into the overhead flame zone in the scene of a fire after, ignite fire-extinguishing mine by heat-sensitive line, in the flame footprint territory, finish aerial or ground stereoscopic intersects fire extinguishing; To not acting on fire-extinguishing mine or not falling into the fire-extinguishing mine in the scene of a fire, according to the fire-extinguishing mine self-destruction time that sets before the emission, fire-extinguishing mine is finished self-destruction after the time, avoids potential safety hazard to occur.

Beneficial effect:

(1) fire-extinguishing mine of the present utility model has been realized the shrapnel filling form of fire extinguisher bomb, has obviously promoted the fire extinguishing effect of extensive forest the scene of a fire, carries out in advance cloth fire-extinguishing mine, opens up the isolation strip, and blocking-up intensity of a fire large tracts of land spreads expansion;

(2) fire-extinguishing mine is self-contained a drag parachute, by self heat-sensitive line, fire-extinguishing mine is slowly fallen in the sky, the scene of a fire, aerial or ground fire-putting-out have been realized in the flame footprint territory, finishing, and guarantee that fire-extinguishing mine reliably lands from high-altitude safe, improve the serviceability of its long-range crossings on different level fire extinguishing;

(3) fire-extinguishing mine self band self-destruction-type fuze has been realized can carrying out self-destruction according to the self-destruction time that sets in advance when normally effect or do not fall into the scene of a fire of fire-extinguishing mine, has improved the fire-extinguishing mine safety in utilization.
