The invention discloses an intelligent normally-open type fireproof door which comprises a door frame, a door leaf is rotationally connected to the inner wall of the door frame through hinges, a hollow interlayer is formed in the side wall of the door leaf, a closing device for closing the door leaf when a fire occurs is arranged in the hollow interlayer, and the closing device comprises a plurality of air storage tanks and an air conveying pipe, namely an exhaust mechanism. The gas storage tank is filled with compressed carbon dioxide; the exhaust mechanism is used for exhausting compressed carbon dioxide in the gas storage tank and comprises an arc-shaped sealing plate, a memory alloy spring and a limiting plate. By arranging the exhaust mechanism, when the temperature rises to the deformation temperature of the memory alloy spring, the memory alloy spring extends and starts the exhaust mechanism, in this way, compressed carbon dioxide in the gas storage tank can be sprayed out at a high speed through the spraying holes, meanwhile, counter-acting force is provided for the door leaf, and therefore the fireproof door is closed to block fire spreading; and the sprayed carbon dioxide can effectively extinguish fire.
本发明公开了一种智能常开式防火门，包括门框，所述门框内壁上通过合页转动连接有门扇，所述门扇的侧壁开设有中空夹层，所述中空夹层内设有在火灾发生时关闭门扇的关闭装置，所述关闭装置包括多个储气罐、输气管即排气机构，所述储气罐内填充有压缩二氧化碳；所述排气机构用于排放储气罐内的压缩二氧化碳，所述排气机构包括弧形密封板、记忆合金弹簧及限位板。本发明通过设置排气机构，当温度上升至记忆合金弹簧的形变温度时，记忆合金弹簧伸长并启动排气机构，如此可将储气罐内的压缩二氧化碳通过喷射孔高速喷出，同时对门扇提供一个反作用力，从而将防火门关闭以阻隔火势蔓延，而且喷射出的二氧化碳还可有效进行灭火。
