Intelligent multi-direction jet spherical fire-extinguishing apparatus

Abstract

The invention relates to the technical field of fire control, in particular to a spherical fire-extinguishing apparatus. The intelligent multi-direction jet spherical fire-extinguishing apparatus comprises a spherical shell, an intelligent trigger controller, a dry powder extinguishing agent and a gas generation agent; jet holes are evenly formed in the spherical shell and sealed through aluminumfoil; the intelligent trigger controller is installed on the spherical shell and comprises a fire behavior detection sensor and a micro-control chip connected with the fire behavior detection sensor;the micro-control chip judges whether or not a fire occurs according to a transmission signal of the fire behavior detection sensor; the gas generation agent is located in the sphere center position of the spherical shell; the dry powder extinguishing agent fills the spherical shell and is separated from the gas generation agent; and the micro-control chip in the intelligent trigger controller isconnected with the gas generation agent through an electric ignition wire, and triggers the electric ignition wire to ignite the gas generation agent when judging that the fire occurs. The intelligentmulti-direction jet spherical fire-extinguishing apparatus puts out the fire in a total-flooding mode, thereby having good dispersity, high dispersivity and high fire-extinguishing efficacy.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a spherical fire extinguishing device. Background technique [0002] The spherical fire extinguishing device is suitable for fire situations where personnel are difficult to access, and has the characteristics of simple and safe fire extinguishing. Though existing spherical fire extinguishing device kind is many at present, mainly there are following problems: [0003] (1) The spherical fire extinguishing device usually uses ordinary dry powder fire extinguishing agent, which has a large particle size (average particle size 30-50 microns), poor dispersion (easy to fall after injection), and slow injection speed, so it is difficult to cover the entire area instantly after blasting. In the fire scene, the surface coverage of the burning object is discontinuous, and the fire extinguishing efficiency is not high. [0004] (2) Most of the injection ports...

AI Technical Summary

Problems solved by technology

[0003] (1) The spherical fire extinguishing device usually uses ordinary dry powder fire extinguishing agent, which has a large particle size (average particle size 30-50 microns), poor dispersion (easy to fall after injection), and slow injection speed, so it is difficult to cover the entire area instantly after blasting. In the fire field, the surface coverage of the burning object is discontinuous, and the fire extinguishing efficiency is not high

[0004] (2) The injection port of the spherical fire extinguishing device is mostly one injection port, which causes the dry powder fire extinguishing agent to be sprayed in a single direction

With delay triggering, the fire extinguishing effect is extremely unstable. If the fire extinguishing distance changes, the corresponding delay time cannot be changed flexibly, and the fire extinguishing device will throw fire extinguishing agent in advance or lag behind the best explosion area, and the fire extinguishing agent cannot be effective. cover

With the impact trigger, the fire extinguishing device can only detonate after reaching the landing point, and the area covered by the fire extinguishing agent is limited by factors such as terrain and explosive environment, and it can only act on an extremely limited area of ​​the fire scene.
