Background

Wind power is an early power utilized by human beings and can be used for pumping water, generating electricity and the like. The wind power plant used is, for example, an early windmill or a current wind power plant.

The existing wind power device mainly has a horizontal shaft type and a vertical shaft type.

The longer the paddle arm of the horizontal axis type wind power device is, the more easily the horizontal axis type wind power device is damaged by wind, the slower the rotating speed is, and the like.

The vertical shaft type wind power device has obvious advantages of no limitation of wind direction, no need of high tower, large wind surface expansibility, convenient speed increase and the like. However, the wind-driven generator has a congenital disadvantage that the vertical axis is used as a boundary, the downwind surface and the upwind surface respectively occupy half of the circumference, and the resistance on the upwind surface cannot be effectively eliminated under the condition of balanced stress on the downwind surface and the upwind surface, so that the proper effect of the downwind surface on wind cannot be exerted. In the prior art, for example, a Chinese utility model patent CN88214948.2 discloses a swing blade type wind turbine; also, as the windmill introduced in CN89219274.7, the blades of the windmill are asymmetric on both sides of the rotation shaft, and the wide side has a large wind-receiving area and the narrow side has a small upwind surface, so as to reduce the resistance on the windward and upwind interfaces. Utility model patent application No. 91103531.1 also discloses a "universal wind generating set of valve" has used parts such as axis of rotation, activity air door, movable pulley, ring rail, and its activity air door can adapt to the wind direction and change, can receive not equidirectional wind-force at any time. However, the technology still has narrow-side upwind surfaces, and the problem of upwind resistance is inevitable. Moreover, these dampers are side-mounted, rotating about a vertical axis, and may fail to close during the switching process, thereby interfering with operation. Therefore, the vertical shaft type wind power device in the prior art can only adapt to small-scale wind power generation, can not adapt to large-scale wind power generation, and has a complex structure.

In order to adapt vertical axis wind power plants to large wind power plants, the applicant has developed a stackable self-controlled windsurfing board windmill (CN 03118024.8).

However, there are also problems: the area of the blade (sailboard) is too large, the blade is difficult to control, the inertia is large, and the blade is easy to damage; when the blades are opened, the wind resistance is large, and the efficiency is low.

Other prior art blades (windsurfing boards) suffer similar drawbacks to varying degrees.
