The cross bar 311 is arranged on the top of the fan blade 313, so that the fan blade Under the action of a small wind force or no wind, it maintains a vertical initial state, and starts to rotate from the initial state after being stressed, without turbulent rotation. The fan blades 313 at both ends of the first connecting rod 32 are arranged perpendicular to each other, and the two fan blades 313 are respectively located on both sides of the limit shaft 2. When each group of fan blade rotating units 3 rotates clockwise or counterclockwise, the The limiting shaft 2 can block one of the first blade assemblies 31 , while the other first blade assembly 31 remains parallel to the direction of the wind force, and the pressure difference on both sides of this group of blade rotating units 3 is the largest.

Blocking is used to limit the blade 313 to maintain a vertical direction after being stressed.

A keel frame 312 is fixedly connected to the fan blade 313. When the blade 313 is made of a hard material, the keel frame 312 is used to reinforce the fan blade so that the limiting shaft 2 can effectively prevent the blade 313 from being vertical and then turn over; When the blade 313 is made of a flexible material (such as skin), it is suitable for a working environment with a high wind force level, so as to avoid damage to the wind blade when the wind is strong. The dragon skeleton 312 can increase the force-bearing area of the wind blade 313 , play the role of supporting the blade.

When the fan blade 313 at one end is perpendicular to the wind direction, the lower part of the fan blade 313 is limited by the limit shaft 2 to rotate and remain vertical. At this time, the fan blade 313 The force-bearing area of the windshield is the largest, and the pressure is the largest; meanwhile, the fan blade 313 at the other end is parallel to the wind direction, and the force-bearing area is the smallest. At this time, the pressure difference between the blades 313 on both sides of the group of blade rotating units 3 is the largest, and the highest rotational speed can be obtained instantaneously, thereby driving the vertical axis generator to rotate and maximizing the conversion of wind energy into electrical energy.
