Abstract

A kind of fire extinguishing shell, after the shell explodes, the dry ice is sublimated into carbon dioxide gas, which has a cooling effect and does not support combustion. The shell shell is made of ceramics, and its shape is a cylindrical streamlined body. The main body of the shell is divided into upper and lower parts. These two parts are connected by screw ports. Tight, airtight seal between the inside and outside of the shell, the detonator, explosives, fuse, and ignition fuze of the detonating device are inserted into the recessed barrel of the shell head as a whole, and the propellant tube is inserted into the tail pipe, and the explosive device And the propellant tube can be removed from the shell, and the tail has fins. Fire extinguishing projectiles use mortars or rocket launchers to launch fire extinguishing to the fire scene.

Description

fire extinguishing shells

technical field

The utility model relates to a fire extinguishing artillery shell for fire fighting and extinguishing.

Background technique

The weak point of the fire extinguishing shell that the patent No. is 98237448 is that the shell is paper, and the paper is easily unfavorable for fire extinguishing, and the fire extinguishing in the shell is that the chemical substance easily pollutes the environment.

Contents of the invention

In order to overcome the shortcomings described in the background technology, the utility model provides a fire extinguishing projectile, which solves the problem that the manufacturing cost of the shell is low and it is not easy to burn. question.

The technical solution adopted by the utility model to solve its technical problems is: the shell of the fire-extinguishing shell is made of ceramics, but it is longer and thicker than the mortar shell, and has a launcher and an explosion device. The fire-extinguishing substance in the shell is dry ice, and the detonator of the warhead, Explosives, fuses, and ignition fuzes are a whole, which can be taken out. The gunpowder at the tail of the shell can be taken out from the tailpipe, and the fire-extinguishing shell can be launched from a launcher; the fire-extinguishing shell is composed of upper and lower parts, which are filled with dry ice and covered with asbestos The upper and lower parts of the gasket are connected by screw ports, and must be airtight.

The dry ice of the utility model is sublimated into carbon dioxide gas after the explosion of the shell, which has cooling effect and does not support combustion, so as to achieve the purpose of fire extinguishing. It can be used to extinguish fire when water cannot be extinguished, or high-rise buildings can be used for fire extinguishing by launching fire extinguishing shells with bazookas, or long-distance fire extinguishing can be used Fire extinguishing cannonballs are launched by mortars, or fire is extinguished in three ways by throwing hands to the fire pile for close-range fire extinguishing.

Detailed ways

Among Fig. 1, the shell 1. shell is made of ceramics, and the shell shell is divided into upper and lower two parts. The head detonating device of the shell has ② impact fuze igniter, ③ fuse, ④ detonator and explosives are connected, and other spaces in the shell are filled with dry ice. The center is isolated, and the detonator is inserted into the recessed barrel of the shell head. The recessed barrel and the shell of the shell are an integral structure. The role of the detonator and the explosive is to blow the shell to pieces. It can scatter the dry ice into half The length is 4 meters: the fuze igniter, fuse, detonator and explosives are isolated from the dry ice. The shell has ⑤ tail fins, which are used to maintain the balance of the shell during flight. Gunpowder can be removed.

When launching fire-extinguishing shells with mortars and bazookas, the tailpipes of launching gunpowder are packed into shells, and the shells launched by mortars touch the ground to the time of explosion is 0.5 seconds. The warhead of the projectile launched by the bazooka can also remove the explosive device, because the ceramic projectile shatters when it hits the wall.

If the bomb is thrown by hand, the propellant powder should be taken out, and the warhead should be knocked on the ground before throwing. The time from the warhead knocking to the ground to the explosion of the shell is 5 seconds, which is for the safety of the bomber.

The fire-fighting shells are stored in a freezer at -80 degrees Celsius, and the temperature of the car during transportation is also -80 degrees Celsius. Each fire-fighting shell is packed in an insulated box.

Claims (2)

1, a kind of extinguishing cannonball, it is characterized in that: shell is a pottery manufacturing, but it is longer and thick than mortar projectile, emitter and destructor are arranged, the extinguishing material of shell the inside is a dry ice, and the detonator of bullet, explosive, fuse cord, igniter fuse are an integral body, can take out, the propellant of shell tail can take out from tail pipe, the emission of extinguishing cannonball available transmission device.

2, extinguishing cannonball according to claim 1 is characterized in that shell is made up of upper and lower two parts, fill put asbestos washer behind the dry ice after upper and lower two parts link to each other with screw-socket, necessarily seal air tight.
