Automatic fire-extinguishing device

Abstract

The invention discloses an automatic fire-extinguishing device, which comprises a fire-extinguishing agent storing cavity, a driving gas storing cavity, a cavity connector and a valve, wherein the fire-extinguishing agent storing cavity is used for storing starting gas and a fire-extinguishing agent; the driving gas storing cavity is used for storing driving gas; the cavity connector is provided with a gas charging valve; the valve is started automatically at the set temperature; the fire-extinguishing agent storing cavity is provided with two first openings; the driving gas storing cavity is provided with a second opening; one end of the cavity connector is connected with one first opening of the fire-extinguishing agent storing cavity by a quick-release type pressure difference check one-way valve, and the other end of the cavity connector is communicated with the second opening of the driving gas storing cavity; and the valve is arranged at the other first opening of the fire-extinguishing agent storing cavity, and is supported by a heated breakable glass bulb. According to the automatic fire-extinguishing device, due to arrangement of the double-cavity structure, the fire-extinguishing agent and the driving gas are isolated, so that not only is the installing height needed by the device reduced, and is the installing position of the device flexible, but also the automatic starting can be achieved when a fire occurs, and the incipient fire is extinguished.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to an automatic fire extinguishing device. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's livelihood and safety awareness, fire-fighting equipment has been widely used, and fire-fighting facilities and fire-extinguishing devices are also equipped in many occasions. At present, the fire extinguishing devices of the prior art cannot be installed in places with narrow space and limited height due to their large volume and capacity, and cannot be automatically activated at the first time when a fire occurs, and can extinguish early fires safely and effectively. Therefore, In some unattended occasions and places with small spaces and limited heights, such as automobiles, yacht engine compartments, luggage compartments, power distribution boxes, power switch cabinets, outdoor communication base stations and...

AI Technical Summary

Problems solved by technology

However, when a fire is caused by factors such as short circuit or current overload in places with live work such as power distribution boxes and power switch cabinets, ordinary personnel cannot use fire extinguishers or fire water to extinguish the fire on site.

Therefore, the fire extinguishing device of the prior art, once a fire breaks out, cannot be started in time, and effectively implements fire extinguishing, thus easily causes the serious consequences such as the spread of fire burnt area and direct economic loss
