Fireproof window automatic closing device in archive room
The invention discloses a fireproof window automatic closing device in an archive room. The fireproof window automatic closing device in the archive room comprises a window frame; a taking cavity which penetrates through front and back is formed in the window frame; a curtain falling device which can close the taking cavity is arranged on the window frame; and the curtain walling device comprisesan accommodating cavity which is positioned on an inner wall of the upper end of the taking cavity in a penetrating manner. According to the fireproof window automatic closing device in the archive room, hot fuse breaks after encountering fire by tightening and fixing the hot fuse to limit the rotation of a shaft with a fireproof curtain by utilizing that the hot fuse may break after being heatedand the melting point is at about 60 DEG C; the shaft rotates to fall the curtain automatically; in addition, an extendable fireproof part communicates with a water flow pipeline, so that the gap between the fireproof curtain and the window frame is filled and wetted to prevent a fire source from entering the archive room; and moreover, a smoke ventilating opening which is opened synchronously through a gear pair is arranged in the upper end so as to prevent smoke dust from entering.
本发明公开的一种档案室内的防火窗自动闭合装置，包括窗户架，所述窗户架内设有前后贯通的拿取腔，所述窗户架上设有可将所述拿取腔封闭的落幕装置，所述落幕装置包括贯通位于所述拿取腔上端内壁上的收纳腔，本发明利用热熔丝受热会断，且熔点在六十度左右，将热熔丝绷紧固定限制带有防火幕布的轴旋转，遇火后热熔丝断裂，轴旋转将防火幕布自动放下，另外，通过可延展的防火部分与水流管道接通，将防火幕布与窗户架边缘缝隙填补打湿，放置火源进入档案室内，另外上端设有通过齿轮副同步开启的通烟口，放置烟尘的进入。
