The working process and principle of the invention are as follows:
the core principle is as follows: the distance between the two hinges on the long sides of the movable long rod 5, the movable long rod 6 and the clamping block 2 and the distance between the two connecting pieces 11 of the movable fan wing 12 are respectively taken as four sides to form a four-rod structure, two ends of the spring 13 are fixed on the movable long rod 5 and the movable short rod 6 and are always in a stretching state, when wind force is enough, due to the centrifugal force, the movable long rod 5 and the movable short rod 6 overcome the action of the centrifugal force to move in the directions away from each other, the spring 13 is further stretched, the tension is increased, after the wind speed is reduced, the centrifugal force is reduced, the tension of the spring 13 enables the two rods to be close again, and the movable fan wing 12 moves in the horizontal plane to form resistance with the fixed fan wing 4.
Resistance morphology:

Due to the tension of the spring 13 in the resistance mode, when the rotating speed of the movable wing 12 reaches the requirement of entering the transition state, the actual centrifugal force is far greater than the requirement of free unfolding, thereby ensuring the transient transition process and the rapid switching of the modes
Lift morphology:
corresponding to the lift force form at high wind speed, the fundamental purpose is to improve the utilization efficiency of the vertical axis device to wind energy at high wind speed. In accordance with the design purpose, the four wings in the lifting mode are connected with the clamping block 2 through the movable long rod 5 and the movable short rod 6 in the unfolding mode by taking the central rotating shaft 1 as a core. Because the device is started at low wind speed, after the device enters a lifting mode, the device keeps rotating at high speed and drives the whole device to do circular motion by four wings.
The lift profile reverts to the drag profile:
