The electric initiator 4 is connected with a controller (not shown) arranged outside the tank body 1 through an electric wire 5, and when the current output to the electric initiator 4 by the controller reaches a preset value (for example, more than 0.55A), high temperature is generated, so that the explosive column 2 is ignited.
In order to improve the burning rate of the grain, the grain 1 of the embodiment can be formed by overlapping two tablets, a burning port 21 is arranged in the middle of each tablet, the thermosensitive wire 3 and/or the electric initiator 4 are arranged in the middle of the two tablets and are positioned at the burning port 21, thus, when the thermosensitive wire 3 and/or the electric initiator 4 generates heat, the two tablets can be simultaneously ignited, the tablets can be rapidly oxidized, a large amount of aerosol fire extinguishing agent is instantly generated, and the fire extinguishing efficiency is improved.
The fire extinguishing tank is characterized in that a plurality of nozzles 11 for releasing the fire extinguishing agent are arranged on the tank body 1, the tank body 1 is formed by joining an upper part and a lower part, and the nozzles 11 are arranged on the joint surfaces of the upper part and the lower part and are uniformly distributed around the tank body 1. When a fire is detected, the extinguishing agent discharged from the nozzle 11 can extinguish the fire from 360 degrees, thereby further improving the fire extinguishing efficiency.
The embodiment can further comprise a flame-retardant wire protecting sleeve 6, wherein the flame-retardant wire protecting sleeve 6 extends from the inside of the tank body 1 to the outside of the tank body 1 and is sleeved outside the thermosensitive wires and the electric wires to protect the thermosensitive wires and the electric wires from being damaged by high temperature. Correspondingly, the tank body is also provided with an interface 12, the thermosensitive wire and the electric wire extend out of the tank body through the interface 12, or the flame-retardant wire-protecting sleeve extends out of the tank body 1 through the interface 12, and the thermosensitive wire 3 and the electric wire 5 are arranged in the tank body in a penetrating manner.
