Abstract
A wind generator has a post, a rail mounted on the post and a blade assembly mounted rotatably on a top of the post. The blade assembly includes multiple blades radially formed around a base. Each blade has multiple vents, a slat and multiple relief valves. The slat is controllable mounted to open or close the vents, so as to adjust a force of wind applied to the blades. The relief valves are mounted pivotally to selectively cover valve holes formed through the blades to prevent the wind resistance force applied to the blades. Therefore, the wind generator can work in both turbulent and with a low wind force without breaking.
