Fire extinguishing device and automatic fire extinguishing isolation belt with fire extinguishing device

Abstract

The invention discloses a fire extinguishing device. The fire extinguishing device comprises a barrel body and an exploder. A through hole is formed in the bottom of the barrel body, the exploder is fixed to the position of the through hole in a sealed manner through an elastic silica gel sealing ring, a fire extinguishing agent is sealed in the barrel body, the exploder is used for exploding andbreaking when heated or subjected to flame attacks, and the fire extinguishing agent flows out after the through hole is opened. A temperature control powder exploder is adopted as the exploder, and powder violently expanding when encountering high temperature is sealed in the exploder. 4,4'-oxydibenzenesulfonyl hydrazide is adopted as the powder. The fire extinguishing device further comprises anouter shell body. A through hole opposite to the exploder is formed in a bottom panel of the outer shell body. The invention further discloses an automatic fire extinguishing isolation belt with thefire extinguishing device. The fire extinguishing device is arranged below the fireproof isolation belt, the situation that when a heat insulating material on the lower face catches fire, the exploderexplodes, and the fire extinguishing agent in the barrel body flows out to the heat insulating material catching fire is achieved, the effect of isolating oxygen and reducing the temperature is achieved, fire behaviors are prevented from spreading upwards rapidly, enough time is conveniently gained for fire extinguishing and crowd evacuating, and the life and property safety of people is protected.

Description

technical field [0001] The invention relates to the field of fire fighting, in particular to a fire extinguishing device and an automatic fire extinguishing barrier including the fire extinguishing device. Background technique [0002] In recent years, under the impetus of national building energy-saving policies and regulations, external thermal insulation technology of high-rise building exterior walls has been widely used. However, there has always been a great hidden danger to the fire safety of the outer insulation layer. [0003] For fires in high-rise buildings, studies have found that the vast majority of fires start from a room inside the building and escape from the window to the outside of the building. The fire spreads rapidly along the outside of the building and quickly reaches the roof, and then passes through the window glass on the upper floor. It was burned and then ignited inside the building, or it was originally ignited from the outside, causing the fla...

AI Technical Summary

Problems solved by technology

This grade A thermal insulation material has good fire resistance performance, and has a certain resistance to the rising flame fire, but its effect is limited, and it still cannot control the flame rising well, so as to win more escape time for people.

[0004] This shows that above-mentioned existing fire protection barrier still has deficiency and defect, and urgently needs to be further improved
