Description

Curtain device for wireless remote control and signal feedback and its reel

The invention relates to a curtain device for wireless remote control and signal feedback and a reel thereof, in particular to a retractable and decentralized action of a wireless remote control curtain, and sends a feedback signal when an abnormality occurs in the reeling and lowering of the curtain. Curtain device and its reel.

According to the existing high-rise buildings, most of the buildings will be equipped with curtains for fire prevention and fire protection in the elevators or at the passages of the floors. In the event of a fire, the fire will be separated from the fire. The smoke curtains are usually unused. At the time, the system is retracted in the chassis, and when the fire occurs, the curtain will be started to fall from the chassis. In order to ensure that the smoke-proof fire curtain can be smoothly raised and lowered to the position during use, it is necessary to carry out regular inspections to avoid the failure of the curtain to be damaged and to lift smoothly, and to lose the effect of blocking the spread of smoke.
