Description

Technical Field

[0002] Smoke exhaust skylights are smoke prevention and exhaust systems set up in accordance with fire protection requirements. They are set on the top of the building and can connect the inside and outside of the building when opened, thereby achieving smoke exhaust. There are currently many ways to classify smoke exhaust skylights, such as by the number of smoke exhaust windows on the window frame. A window frame with one smoke exhaust window is a single-opening smoke exhaust skylight, and a window frame with two smoke exhaust windows is a double-opening smoke exhaust skylight. Among them, a single-opening smoke exhaust skylight is prone to backflow problems if the wind direction is facing the smoke exhaust window after it is opened, which is not conducive to smoke exhaust. Double-opening smoke exhaust windows can solve this problem well, so they are more widely used.

[0003] The existing double-opening smoke exhaust skylight generally sets a driving system inside the window frame, and then drives the two smoke exhaust windows to open or close respectively; however, this structure will easily affect the smoke exhaust effect due to occupying a certain coverage area when the smoke exhaust window is open, and it is also easy to cause pollution and damage to the driving system during the long-term smoke exhaust process, thereby affecting the normal operation of the driving system.
