Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The spherical body 1 is of a hollow structure, a spherical frame 3 is glued in the spherical body 1, and in a preferred embodiment of the invention, the spherical body 1 and the spherical frame 3 are made of metal materials with good heat conductivity, such as aluminum and copper.
The outer surface of the ball body 1 is symmetrically provided with two extending parts 2 by taking a ring shape surrounded by the injection channel 10 as a center, and the extending parts 2 are arched. The arrangement of the extending parts 2 at two sides plays a role in limiting, so that the ball body 1 can only roll along the ring shape enclosed by the injection channel 10, and the triggering is convenient.
The ball-shaped frame 3 is of a ball-shaped structure, the middle part of the ball-shaped frame 3 is a ball center 6, a plurality of injection channels 10 pointing to the ball center 6 are annularly arranged on the ball-shaped frame 3 at equal distances, openings are arranged on the ball 1 corresponding to the injection channels 10 to enable the ball to be communicated with the outside, and at least one needle body 8 is arranged at the opening of each injection channel 10;
an air cavity 5 is formed in the side wall of the injection channel 10, one side of the air cavity 5 is communicated with one side, close to the inside, of the injection channel 10, the other side of the air cavity 5 is communicated with a material cavity 4, one side of the material cavity 4 is attached to the arc surface of the sphere 1, and foaming agents are filled in the material cavity;
the lowest reaction thermal decomposition temperature of the foaming agent is 50 ℃, the foaming agent and the fire extinguishing dry powder both adopt sodium bicarbonate, the sodium bicarbonate is gradually decomposed into carbon dioxide and water at the temperature of more than 50 ℃, wherein the carbon dioxide can drive the film 9 to expand on one hand and extinguish fire on the other hand.
A film 9 is glued at the joint of the air cavity 5 and the spraying channel 10, and the inner side of the film 9 is filled with fire extinguishing dry powder.
Two stop dogs 7 are symmetrically arranged at the joint of the air cavity 5 and the injection channel 10, the stop dogs 7 are of fan-shaped structures, one side close to the air cavity 5 is an arc surface, the arc surface is convenient for the film 9 to be arranged along the arc surface, and on the other hand, the gas can enter along the arc surface.
The gas that decomposes when the foamer reaches minimum thermal decomposition temperature drives film 9 inflation, and film 9 is continuous constantly to be increased in spraying passageway 10, and when its surface bumps and touches needle body 8, all power concentrate on the discontinuity of needle body 8 for film 9 breaks, and cracked in the twinkling of an eye, the gas and the baking soda that use carbon dioxide as the owner in film 9 spray and go out, and spheroid 1 bounces at gaseous reaction force simultaneously, makes and sprays the scope of putting out a fire grow, and the baking soda that sprays then decomposes into carbon dioxide and makes flame suffocate. Because the quantity of the material cavity 4 and the spraying channel 10 is multiple, the material cavity can be sprayed for multiple times, and the problem of incomplete fire extinguishing on one side is avoided.
