Electric-control skylight capable of being automatically opened under power failure

Abstract

The invention discloses an electric-control skylight capable of being automatically opened under power failure. The electric-control skylight comprises a window frame and louvers which are rotatably connected in the window frame, wherein the left sides of the louvers are rotatably connected with the inner side of the left side wall of the window frame through pin rolls; distances between the pin rolls and the rear side walls of the louvers are greater than those between the pin rolls and the front side walls of the louvers; the upper end surface of the right side wall of the window frame is fixedly equipped with a linear motor; a connecting mechanism for connecting the louvers for enabling the louvers to rotate in the window frame around the pin rolls is mounted on a secondary stage of thelinear motor; and an electromagnetic lock for locking the louvers when the louvers are closed is arranged on the upper end surface of the rear side wall of the window frame. Compared with the prior art, the electric-control skylight has the advantages that a power supply is accessed, the linear motor acts, the skylight is automatically closed and is stopped at a closed position for a long time, and the linear motor does not consume power continuously by interrupting the power supply after the skylight is closed. When a fire disaster occurs to cause power interruption, the skylight must be opened automatically, so that the energy-saving and environment-friendly purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of skylights, in particular to an electric adjustable skylight that automatically opens when power is off. Background technique [0002] IDC computer rooms are now being built in large numbers, and more and more advanced micro-modules are used. The skylight is an important component of the cold aisle of the micro-module. It is usually closed to prevent the loss of cold air in the aisle, so as to cool down the equipment in the cabinet and save energy. When a fire breaks out, the skylight is required to be opened automatically, even if the power is cut off, it must be opened automatically, so that the fire extinguishing material can smoothly enter the passage to achieve the purpose of extinguishing the fire. In the past, the skylights were generally closed manually (some also have electric closing). When closing, the window leaf was strongly sucked by the magnetic lock to make it airtight. Open. Due to the ...

Problems solved by technology

Due to the large number and high power of the magnetic lock, it needs to be powered on for a long time, which consumes a lot of power and has a short life, which does not meet the concept of energy saving and environmental protection.
