The action process of the invention: when the wind direction is blown from 6 o ' clock to 12 o ' clock, taking one wind film 2 as an example when the rotating shaft 1 rotates anticlockwise, when the wind film is positioned in the 6 o ' clock direction, the corresponding wind film frame 10 is attached to the bearing net 7 along the wind direction, namely, the wind film frame 10 is always attached to the bearing net 7 along with the rotation of the wind film frame 10 from the 6 o ' clock direction to the 12 o ' clock direction, the wind film 2 expands along with wind along with the rotation of the wind film frame 10 from the 12 o ' clock direction to the 6 o ' clock direction, the wind film frame 10 leaves the bearing net 7 along with the wind film 2, and the wind film 2 dynamically changes along with the wind direction due to the existence of the free edge of the wind film 2, so that the wind film frame 10 keeps consistent with the wind direction, and the resistance is reduced; along with the rotation of the wind film frame 10 to the direction of 6 o' clock, the wind film frame 10 is attached to the bearing net 7 again, a circle of circulation is completed, and the like, and under the continuous action of wind force, the rotating shaft 1 continuously performs circular motion to drive the load to do work.
