Abstract:
Disclosed is a wind power self-adaption louver, comprising a window frame (2) and further comprising a plurality of blades (1) arranged one above the other and connected to the window frame (2) through cross shafts (4) respectively, each of the blades (1) being of a linkage structure. The included angle between the lateral side of the blade (1) and the vertical direction is in the range of 0-45°, and a gravity drive piece (3) rotating together with the blade (1) is provided on the cross shaft (4) on at least one end of each of the blades (1). The gravity drive piece (3) is of a structure capable of providing the blade (1) with a torque enabling the blade to rotate in a horizontal direction, and the blade (1) is of a structure capable of being pushed by the outdoor wind power to rotate in a vertical direction. According to the wind power self-adaption louver, the rotation of the blades does not need to be controlled by electric power and can automatically adapt to the rotation angles of the blades under the combined action of the gravity drive pieces and the outdoor wind power.
