Automatic control extinguishing device for fast sucking, discharging and spraying water

Abstract

An automatic control extinguishing device for fast sucking, discharging and spraying water belongs to an indoor automatic extinguishing device. An air change frame blade is installed indoors. The frame blade unfolds outwards by the operation of the opener. An ionization type smoke detector, a water valve and a sprayer head are installed in frame blade. A choke valve high pressure positive blower is equipped outside the floor and connected with the frame blade by an iron sheet tube. Under normal condition, the fan blade veers for ventilation and air change. When occurring the fire smoke, the ionic smoke detector sends out instructions to ask an opener motor to work, support the frame blade outwards, open the water valve to spray water for extinguishing; meanwhile, the pressure plate choke valve heavy pressure fan reverses for air suction to make the frame blade in the normal room closed automatically, independently fast sucking the harmful smoke and flame in the fire room, thus preventing the smoke and flame from spreading to the other rooms and relief passage for automatic extinguishing.

Description

Technical field [0001] The invention relates to an indoor automatic fire extinguishing device, in particular to a fire extinguishing device which uses an ion-sensing smoke sensor to command a pressure plate choke valve high-pressure fan to automatically absorb smoke and spray water indoors. Background technique [0002] When a fire breaks out indoors, chemical fiber plastic products such as interior decoration and furniture and clothes will produce extremely harmful gases after burning. Many parties will open the windows first because of panic. Because the emergency corridors of high-rise buildings lead directly to the roof, once a fire occurs, the corridors are like chimneys. When the smoke and flame are absorbed outward, the fire spreads rapidly, so that the residents on the upper floors who caught fire cannot escape to the corridor with dense smoke, and are thus suffocated to death by the harmful smoke. Contents of the invention [0003] In order to overcome the deficie...
