Fire safety early warning device

Abstract

The invention provides a fire safety early warning device which comprises a mounting frame, an output port is formed in the top of the mounting frame, the bottom of the mounting frame is in a hollow state, a first exhaust pipe is fixedly inserted into the mounting frame, a first fan is fixedly mounted at the bottom of the first exhaust pipe, and a smoke monitoring head is rotatably mounted at a spoke at the bottom of the first fan. Under the action of the rubber curtain, after the rubber curtain is unfolded along the end opening, a circular-truncated-cone-shaped air inducing cover is formed, air is guided, compared with the prior art, air with dust penetrates through the sensing probe through the air suction effect of the first fan, and compared with slow diffusion of the dust air, the monitoring efficiency is higher; under the action of a second fan and a rubber curtain, gas with dust is exhausted to the outside through strong air draft, the smoke concentration in a fire room is reduced, and compared with a mode of extinguishing fire only through water spraying, guarantee is more effectively provided for the personal safety of trapped persons.

Description

technical field [0001] The invention relates to the field of fire safety, in particular to a fire safety early warning device. Background technique [0002] When a fire occurs, the smoke usually causes the trapped person to pass out using oxygen. The smoke alarm is a common sensing instrument in fire safety. It monitors the space by sensing the concentration of smoke in the air, and automatically when a fire occurs. Alarm. At present, most of the alarm system and fire extinguishing system in fire safety work separately. Simple fire extinguishing work is carried out through the alarm of the smoke alarm and the sprinkler of the fire sprinkler, but this method cannot solve the large amount of smoke generated by the fire in the room. , and only relying on fire sprinklers can not achieve rapid fire extinguishing in a short period of time, nor can it prevent the generation of smoke, and because the height of the room where the alarm is installed is different, the sensitivity to sm...

Problems solved by technology

[0002] When a fire occurs, the smoke usually causes the trapped person to faint with oxygen. The smoke alarm is a common sensor in fire safety. It monitors the space by sensing the concentration of smoke in the air. When a fire occurs, it automatically Alarm, at present, the alarm system and fire extinguishing system in the fire safety mostly work separately. The simple fire extinguishing work is carried out through the alarm of the smoke alarm and the sprinkler of the fire sprinkler, but this method cannot solve the large amount of smoke in the room due to the fire. , and in a short period of time only relying on fire sprinklers cannot achieve rapid fire extinguishing, nor can it prevent the generation of smoke, and because the room where the alarm is installed is different in height, the sensitivity to smoke monitoring is also different, so ordinary smoke alarms cannot be used in fires. The alarm can be called as soon as it happens. Once the fire is too large, the trapped people will lose the best time to escape.
