Description

Bullet throwing and separating device of accurate guidance fire extinguishing bomb

Technical Field

The utility model belongs to the shrapnel of fire extinguishing bomb field of shedding, concretely relates to accurate guidance fire extinguishing bomb's bullet shedding separator.

Background

The fire extinguishing bomb with accurate guidance has high efficiency and accurate striking, and can be widely applied to oil depot fire, chemical plant fire, high-rise fire, forest fire rescue and the like. The fire extinguishing efficiency of the accurate guidance fire extinguishing shrapnel is more efficient, and in practical application, the shrapnel carries out large-area coverage fire extinguishing with the advantage of the number of the bullets. In this process, the technique of throwing the fire extinguishing bullet is particularly critical. The existing sub-ammunition throwing technology is divided into three forms according to a throwing power source: inertial kinetic energy throwing, mechanical force separation throwing and medicine throwing and gas spreading pushing. The throwing mode is not practical in low-altitude or ultra-low-altitude throwing because no additional power source is used for providing power; the mechanical force separation projection is that in the process of projecting a bullet, component force for separating the bullet from a mother bullet is given under the action of the weight of the bullet and mechanisms such as a guide rod spring or a poking spring, and the like, so that the structure is complex, the cost is high, and the elastic-price ratio of the fire extinguishing son-mother is too low; the propellant powder throwing gas pushing mode is that high-temperature and high-pressure gas released by burning gunpowder or explosive pushes the bullet to throw away from the parent body, so that high bullet throwing speed and controllable throwing and spreading can be obtained, and the propellant powder throwing gas pushing mode is a widely used throwing mode for the conventional shrapnel. According to different mediums of gas action, the propelling mode of the fuel gas for spreading the fire-extinguishing agent can be divided into a central pipe explosion mode, a piston type mode, a corrugated pipe mode, a gas bag type mode and the like, the spreading method is more, and a device suitable for spreading the fire-extinguishing shrapnel needs to be further explored.
