Circular-arc automatic louver

Abstract

The invention discloses a circular-arc automatic louver. The circular-arc automatic louver comprises a steel structural frame, wherein the steel structural frame is connected with a motor; the motor is connected with a reduction box by virtue of a clutch; the reduction box is connected with one end of a drive shaft with a universal joint; the other end of the drive shaft with the universal joint is connected with a gear; the gear is engaged with an arc gear rack; the arc gear rack is connected to the bottom surface of an arc window sash; and the reduction box is connected with a damping device. In case of a fire hazard, a dormer window can be completely opened without occupying space. The circular-arc automatic louver has the characteristics of split sliding, self locking and wind countering, the opening of an arc louver body is not influenced no matter from which direction wind blows. A T-shaped beam is embedded in the arc window sash, and the penetration of rain, snow, dust and the like can be prevented better. The top space of a building is saved more, and an arc design is more attractive. Snow and rain are not easily accumulated on an arc surface, so the arc surface can bear higher pressure from rain and snow, and has higher structural strength. The circular-arc automatic louver is used for large-sized buildings, such as large-sized shopping centers, exhibition halls, gymnasiums, airports, railway stations, subways, natatoriums and the like.

Description

technical field [0001] The invention relates to an automatic skylight for the roof of a large building. Background technique [0002] The specification of Chinese patent 200920201256.3 discloses a sunroof that can be opened automatically. The sunroof includes a sunroof frame, a guide rod, a sliding wheel set, a running mechanism, and a fuse. The guide rod is fixed on the lower part of the skylight frame. Two sliding wheels are fixed on the sliding wheel supporting beam according to the linear arrangement of the slope, and the guide rod at the bottom of the sunroof frame matches the sliding wheels. The skylight occupies a large space, is prone to snow accumulation and rain, and has poor structural strength. Contents of the invention [0003] In order to overcome the defects that the known skylight occupies a large space, is prone to snow and rain, and has poor structural strength, the invention provides an arc-shaped automatic skylight, which occupies a small space and i...
