Problems solved by technology

However, the driving method using lead wires has certain limitations. For example, it must be fire-proof and moisture-proof during storage, and the lead wires should also be prevented from falling off. At the same time, when the lead wires are accidentally burned, there is a certain danger when the driving medium expands and ruptures.

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0020] Including a sphere 1, the sphere 1 adopts a hollow structure, and a spherical frame 3 is glued inside the sphere 1. In a preferred embodiment of the present invention, the sphere 1 and the spherical frame 3 are all made of metals with good thermal conductivity such as aluminum and copper. Material.

[0021] The outer surface of the sphere 1 is symmetrically provided with two extensions 2 around the ring surrounded by the injection channel 10, and the extensions 2 are arched. The setting of the extensions 2 on both sides plays a role of limiting, so that the ball 1 can only roll along the ring circle surrounded by the injection channel 10, so as to facilitate t...

Abstract

The invention discloses a self-jetting type fire extinguishing ball, and relates to the technical field of firefighting equipment. The self-jetting type fire extinguishing ball comprises a ball body.The ball body is of a hollow structure, and a spherical frame is glued in the ball body. The spherical framework is of a spherical structure, a ball center is arranged in the middle of the spherical frame, multiple jetting channels pointing to the ball center are annularly formed in the spherical frame at equal intervals, and openings are formed in the positions, corresponding to the jetting channels, of the ball body to enable the ball body to communicate with the exterior. The characteristic that a foaming agent is heated to be decomposed is utilized, decomposed carbon dioxide gas can support thin films, when the thin films are broken, the ball body is driven to pop up through counter acting force of the thin films, sodium bicarbonate and carbon dioxide in the ball body are jetted out, then the fire extinguishing ball has the prominent characteristics that no lead or other danger trigger mechanisms are needed, jetting fire extinguishing is achieved through heat decomposition of the foaming agent, meanwhile, compared with a traditional lead structure, storage is better facilitated, the jetted carbon dioxide and other decomposers are harmless, and higher environmental protection isachieved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a self-spraying fire extinguishing ball. Background technique [0002] Fire extinguishing ball, when a fire occurs, roll the ball into the fire or hang the fire extinguishing ball in a place prone to fire. The fire extinguishing ball will automatically spray dry powder after encountering an open fire to achieve the effect of automatic fire extinguishing. The fire extinguishing ball device consists of a foam shell, a built-in dry powder drive device, and ABC dry powder fire extinguishing agent. The outside of the fire extinguishing ball device is wound with a cross-shaped lead wire. When the external lead wire is ignited, the driving medium is activated, and the inside of the shell expands and ruptures rapidly. It is extinguished under the dual action of physics and chemistry of dry powder fire extinguishing agent. However, the drive method using lead wires has c...
