Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 , figure 2 As shown, the structural representation and the sectional view of the fire-fighting shell of the present invention are provided respectively, and it is made of projectile body 1, rear cylinder body 3, front cylinder body 4, explosive 5, fin 6, ignition powder, time-delay lead wire 8, instant The lead wire 9, the push ignition device and the ignition device at the front end are composed. The projectile body 1 shown is composed of fire-fighting materials. The interior of the projectile body 1 is a central cavity 2. 1's rear end and front end, and both communicate with the central cavity 2. There are multiple fins 6, and the plurality of fins 6 are evenly distributed on the periphery of the rear barrel 3, which is beneficial to enhance the stability of the shell during flight and prolong the flight distance. The explo...

Abstract

The invention relates to a fire-fighting projectile. The fire-fighting projectile comprises a projectile body assembly and a propelling assembly, wherein the projectile body assembly comprises a projectile body, an explosive, a rear cylinder body, a front cylinder body and a plurality of fins, the projectile body consists of fire-fighting substances, a central cavity is formed in the projectile body, and the explosive is arranged in the central cavity. The fire-fighting projectile is characterized in that the propelling assembly comprises a base plate, a piston, a reset spring and a plurality of connecting plates; the rear ends of the connecting plates are uniformly fixed on the base plate, and the front ends of the connecting plates are fixed with the fins through connecting steel wires; and the tail end of the rear cylinder body is filled with an ignition charge, the ignition charge is connected with the explosive through a delay lead, the piston is fixed at the center of the base plate and is used for extruding and igniting the ignition charge, the reset spring is located between the base plate and the fins, plays a role of insurance and is used for separating the projectile body assembly from a propelling ignition assembly after the projectile is shot. The fire-fighting projectile plays a role of insurance by virtue of limitation of the reset spring and the connecting steel wires, and by virtue of thrust of the propelling assembly to the rear cylinder body and the fins, the firing range of the fire-fighting projectile is increased. The fire-fighting projectile has the advantages of being simple in structure, good in fire extinguishing effect, remarkably beneficial effects and suitable for being applied and popularized.

Description

technical field [0001] The invention relates to a fire-fighting shell, more specifically, to a fire-fighting shell capable of spraying fire-fighting substances on the surface of a burning object. Background technique [0002] As the saying goes, water and fire are ruthless, how to ensure the safety of people's lives and properties to the greatest extent in a fire is the main purpose of fire protection. However, with the construction of urbanization and the construction of factory buildings, when a fire occurs, the existing fire-fighting methods may not be able to achieve the fire-fighting effect. For example, when a high-rise building in a town is on fire, the existing fire extinguishing water guns may not be able to spray it; when a factory building with a risk of explosion is on fire, it is difficult to carry out fire extinguishing operations close to the fire area. To achieve a good fire extinguishing effect. For example, the patent No. is 2015109686317, and the inventi...
