The rain shielding device comprises a driving rotating shaft 3, a driving blade 4 fixedly connected with the driving rotating shaft and a driven blade 5 hinged with the driving rotating shaft; when the driving rotating shaft rotates, the driving blade can be driven to synchronously rotate. And the driven blade is hinged on the driving rotating shaft, so that the driven blade cannot be influenced when the driving rotating shaft rotates.

When the driving rotating shaft rotates, the driven rotating shaft can be driven to rotate in the opposite direction. One end of the driving rotating shaft is connected with an output shaft of the motor 8 in a transmission way, so that the motor provides rotating power for the driving rotating shaft.
The teeth of the driving rotating shaft are positioned in the middle of the driving rotating shaft; the connecting points of the driving rotating shaft and the driving movable blade are positioned on two sides of the teeth; connecting shafts are fixed at both ends of the driving rotating shaft; the connecting shaft is fixed on the bracket through a bearing; the driven movable vane is sleeved on the connecting shaft through a bearing arranged on the supporting leg, so that the driven movable vane can rotate relative to the driving rotating shaft.
