Air-supply type fire-fighting smoke extractor

Abstract

The invention discloses an air-supplying type fire-fighting smoke extractor. The structure of the smoke extractor comprises bases, a ventilation protection filter screen, a smoke extractor, a controller, an electric quantity display screen, a switch indicating lamp, a switch key and a connecting wire, the number of the bases is four and are all arranged below the smoke extractor, the top surface of the bases are welded with the bottom surface of the smoke extractor, the ventilation protection filter screen is arranged on the left side of the smoke extractor and is in an integrated structure with the smoke extractor, the controller is arranged on the right side of the top surface of the smoke extractor, and the bottom surface of the controller is welded with the top surface of the smoke extractor, one side of the controller is provided with a connecting wire, and one end of the controller is welded with one end of the connecting wire. Through the combination of the above components, dueto the fact that the pull rod, the crow plate and the like are added, the smoke extractor is enabled to be in use, the vibration force generated can be reduced by the smoke extractor during working,the device is not prone to toppling when being used, and the stability performance can be improved.

Description

technical field [0001] The invention is an air-supply type fire-fighting smoke exhauster, which belongs to the field of fire-fighting equipment. Background technique [0002] The fire smoke exhaust machine is one of the smoke prevention facilities of high-rise buildings. The smoke prevention facilities of high-rise buildings create favorable conditions for safe evacuation and fire fighting during fires, and control the spread of fire. It is used for smoke exhaust in high-rise buildings. Its function is to make the smoke exhaust of the internal walkway or basement of the building without natural windows and the length of more than 20 meters. Once a fire breaks out in a high-rise building, indoor combustibles, building materials, decoration materials, combustible furniture, clothing and other combustible items will produce a large amount of toxic smoke and heat during the combustion process. People are suffocated, poisoned and still die. In order to prevent the lives of peop...
