Abstract
The utility model relates to a dry ice fire extinguishing bomb, which belongs to fire fighting equipment. After gun powder inside an emission chamber of the utility model can be triggered or the utility model can be aerially delivered, the utility model can keeps a warhead downward under the condition that the utility model has the falling phenomenon because of the function of a tail fin. Sealing surfaces are separated because of inertia, and a movable lug is clamped by a groove. Dry ice inside a bomb body is in the environment with high pressure and high temperature, and thereby, gas CO2 which is evaporated can be used for extinguishing fire and cooling down temperature. The utility model is suitable for fire extinction in a long distance.
Description
The utility model belongs to fire-fighting equipment, is a kind of dry-ice fire extinguisher bullet.
Fire is to one of disaster of people's life and composition of estate significant threat, so people have designed many kinds of fire-fighting equipments, but they a common deficiency is all arranged is exactly that the fire extinguishing personnel must close on the scene of fire, therefore, life safety is had very big threat.
The inspiration that the utility model is forced to the shell emission produces: empennage keeps bullet to utilize the effect of inertia of body to open the extinguishing chemical outlet downwards in the time of can making the body tenesmus, and have movable lug to be stuck in to make it be held open state in the groove always, and dry ice only could keep its state under low temperature or high pressure, otherwise, will be evaporated to the gas dioxo gas, it is a kind of good extinguishing chemical, and its temperature is reduced to below-80 ℃ during dry ice evaporates, fire district temperature is reduced and destroys burning condition.
The utility model purpose just provides a kind of remote, and can discharge the fire distinguisher of low temperature, extinguishing chemical that extinguishing property is good.
The purpose of this utility model is achieved in that a kind of dry ice fire extinguisher bomb, comprises dry ice chamber (1), bay (2), empennage (3), body connection place (4), bullet top (5), sealing surface (6), groove (7), movable lug (8), bullet and seal connection place (9), gas CO
2Outlet (10), when it is characterized in that triggering interior gunpowder of bay (2) or the tenesmus of air-drop back body empennage (3) effect down bullet push up (5) and utilize inertia to make sealing surface (6) separation, gas CO straight down
2Outlet (10) evaporates CO
2Can realize remote fire extinguishing.
Adopt the utility model will obtain following effect:
1, because the fire extinguishing personnel needn't be secure to personal safety near burning things which may cause a fire disaster.
2, dry ice evaporates is gas CO
2The back is good extinguishing chemical, and absorbs a large amount of heat in its evaporation process, thereby reduces the fire zone temperature in case resume combustion.
3, CO
2Fire extinguishing adapts to wide.
The utility model is described in further detail below in conjunction with accompanying drawing, and accompanying drawing is the utility model generalized section:
As shown in the figure, when it is in stand-by state, because the pressure effect of dry ice makes sealing surface (6) closely contact movable lug (8) in groove (7) top.After after triggering bay (2), launching or dropping, when body drop,, when landing, utilize to make movable lug (8) move to the position of groove (7) under the inertia force effect, and be stuck because the effect of empennage (3) makes bullet top (5) maintenance straight down.This moment sealing surface (6) separation of C O
2Gas vent (10) is located pressure and is lower than dry ice chamber (1), and then dry ice is by CO
2Gas vent (10) evaporation.Groove (7) is gas CO
2An annular groove on outlet (10) road, movable lug (8) is a pair of triangle body.Can utilize the mortar emission, or utilize air-drop, can cast out bay (2), when fire is not serious, can be used as a kind of hand-held fire-extinguisher, at this moment can clash into bullet top (5), sealing surface (6) is separated, it is aimed at burning things which may cause a fire disaster if be used for air-drop.
Claims (2)
1. a dry ice fire extinguisher bomb comprises (5) sealing surface (6) groove (7) movable lug (8) bullet top, bullet top, dry ice chamber (1) bay (2) empennage (3) body connection place (4) and sealing surface connection place (9) atmospheric carbon dioxide outlet (10).It is characterized by to have designed in atmospheric carbon dioxide outlet (10) by bullet top (5) has a pair of movable lug (8) with bullet top (5) sealing surface (6) that sealing surface connection place (9) are associated at their middle parts, and a circle groove (7) is arranged on the gas vent wall.
2. dry ice fire extinguisher bomb according to claim 1 has a body connection place on its body.
