Fire-fighting smoke exhaust window
The fire-fighting smoke exhaust window comprises cross-flow fans, an outer window frame and an inner window frame, the outer window frame and the inner window frame are arranged on the outer side and the inner side of a reserved window of a building correspondingly, the four cross-flow fans are arranged between the outer window frame and the outer wall of the building in a circle, and air inlets are formed in the cylindrical surfaces of one sides of the cross-flow fans; an air inlet is formed in one side of the cross-flow fan, an air outlet is formed in the cylindrical surface, perpendicular to the side provided with the air inlet, of the cross-flow fan, and the other side, opposite to the side face provided with the air outlet, of the cross-flow fan is fixedly connected with the outer wall face of the building. The air ejection effect is triggered by air viscosity and the Bernoulli principle, air in the building can be actively exhausted outwards under the condition that the air in the building is not connected or sucked in, structural damage or motor overheating caused by contact with smoke or hot airflow can be avoided when a fire occurs, the smoke exhaust time is prolonged to the maximum extent, and fire loss is reduced.
本发明公开了一种消防排烟窗，它包括贯流风机、外窗框和内窗框，外窗框和内窗框分别设置于建筑物预留窗口的外侧和内侧，其中外窗框与建筑物外墙之间环绕一周设置4个贯流风机，贯流风机一侧柱面设置进气口，贯流风机与设有进气口一侧垂直的柱面设置排气口，贯流风机设有排气口侧面相对的另一侧与建筑物外墙面固定连接设置，本发明与现有技术相比的优点在于：本装置具备多个向建筑物外侧吹风的风机，并且安装于建筑物外墙，靠空气黏性和伯努利原理引发空气引射效应，可做到在不接和吸入触建筑物内空气的情况下主动将建筑物内空气向外排放，当火灾发生时可避免与烟雾或热气流接触而造成结构损坏或电机过热，最大限度增加排烟时间，降低火灾损失。
