Description

Indoor fire early warning and extinguishing device

Technical Field

The utility model belongs to the technical field of the fire control facility field specifically is an indoor fire early warning and extinguishing device.

Background

Since the human being can use and apply the fire freely, the fire has been one of the main disasters threatening public safety and social development most often and generally. In order to cope with the disasters, various early warning and fire extinguishing devices are continuously invented and created, the most common early warning equipment is a smoke alarm at present, and the most common fire extinguishing device is a conventional fire extinguisher. The fire extinguishing mode is different according to different burning substances or burning places, but the four basic fire extinguishing modes, namely an isolation method, cannot be distinguished: isolating or removing the place or object on fire from the surrounding combustibles, the combustion will stop due to the lack of combustibles; asphyxia method: preventing air from flowing into the combustion area or diluting the air with non-combustible substances, so that the combustion products can not obtain enough oxygen to extinguish; a cooling method: spraying a fire extinguishing agent directly onto the combustion products; to reduce the temperature of the combustion products. When the temperature of the combustion products drops below the ignition point of the products, combustion is stopped; chemical suppression fire extinguishing method: the chemical fire suppressant is injected into the combustion zone to participate in the chemical reaction of combustion, thereby stopping combustion. The selection of fire suppression is different according to different needs. Although a fire alarm system is provided in a room, particularly a warehouse, when a fire breaks out, the fire is difficult to be splashed out in time, which often causes a great amount of money loss, and small fire extinguishers are difficult to be splashed out for a large fire which is already burnt in order.
