Abstract

The utility model relates to a fire extinguishing cannonball which can achieve the object of extinguishing fire as dry ice is sublimated to carbon dioxide gas that has temperature reduction effect and does not support combustion after the cannonball exploding, and the cannonball can extinguish the fire in the far distance or tall buildings. A cannonball case is made of ceramics and takes a shape of a column streamline body; the main body of the cannonball is divided into an upper part and a lower part which are connected by using a screw-socket and the two parts are screwed tightly after the interior of the cannonball is filled up with the dry ice and the kneck is sheathed with an asbestos gasket; the cannonball is sealed between inside and outside thereof and does not leak air; a detonator, explosive, a detonation cord and an igniting fuze of an explosive device are one integration which is inserted into a concave barrel at the head of the cannonball; a propellant tube is inserted into a tail tube; the explosive device and the propellant tube can be taken out from the cannonball; and the tail of the cannonball is provided with fins. The fire extinguishing cannonball is launched to the fields with accidental fire by a trench mortar or a rocket launcher so as to extinguish fire.

Description

Extinguishing cannonball

Technical field

The utility model relates to a kind of extinguishing cannonball of fire-fighting fire extinguishing.

Background technology

The patent No. is that the weak point of 98237448 extinguishing cannonball is that shell is a paper, and paper easily so is unfavorable for fire extinguishing, the fire extinguishing in the bullet be the easy contaminated environment of chemical substance.

Summary of the invention

The utility model provides a kind of extinguishing cannonball in order to overcome the deficiency described in the background technology, and the low cost of manufacture that has solved shell is nonflammable again, and the filler in the bullet has not to be supported to burn and the duplex of lower the temperature is imitated the problem free from environmental pollution again of putting out a fire.

The technical scheme that its technical problem that solves the utility model adopts is: the shell of extinguishing cannonball 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, 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; Extinguishing cannonball 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.

The utility model is shellbursted the back dry ice sublimation and is become carbon dioxide to have cooling effect not support burning again, reach the purpose of fire extinguishing, in the time can not fire-fighting by water, be used for putting out a fire, or skyscraper is put out a fire with rocket launcher emission extinguishing cannonball, or remote fire extinguishing can launch extinguishing cannonball with mortar, or closely puts out a fire and throw three kinds of modes and put out a fire with the hand heap that warms oneself in front of a fire.

Description of drawings

Fig. 1 is the extinguishing cannonball cutaway view.

Fig. 2 is that bullet draws sudden and violent device.

Fig. 3 is the propellant pipe view of shell tail.

The specific embodiment

Among Fig. 1 shell 1. shell be that pottery is made, the shell shell is divided into upper and lower two parts.The head of shell draws sudden and violent device 2. impacting type fuse igniter, 3. fuse cord, 4. detonator links to each other with explosive, what other spaces in the shell were adorned is dry ice, the apparatus to cause bursting of dry ice and bullet and the propellant of projectile tail are isolated in shell, drawing sudden and violent device is to insert in the recessed tube of shells head, the recessed tube and the shell of shell are overall structures, the effect of detonator and explosive is fried the falling apart of shell, it can dry ice let go half through being 4 meters: the fuse igniter, fuse cord, detonator and explosive and dry ice are isolated, shell has 5. empennage, when being shell flight, effect keeps balance, 6. be the tail pipe of putting propellant, the inside dress propellant, propellant can take out.

Pack into the tail pipe of shell of propellant, land time of blast of the shell of mortar emission is 0.5 second during with mortar, rocket launcher emission extinguishing cannonball.The bullet of the shell of rocket launcher emission also can take out destructor, has just crashed because the shell of pottery is run into wall.

If drop a bomb with hand, take out propellant, bullet is knocked on the ground throws again, from bullet knock to the time of shellbursting be 5 seconds, be safety for the people that drops a bomb.

Extinguishing cannonball is stored in-80 degrees centigrade the refrigerating chamber, and the railway carriage temperature when transportation also is-80 degrees centigrade, and each piece extinguishing cannonball is being adorned by a hot box.

Claims

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.
