<p>A wind power generation device comprises a generator (10), a rotating shaft (20) connected to the generator rotatably, multiple blade sets (30) which are disposed on the rotating shaft respectively, and multiple stop members (50) which are connected to the rotating shaft and correspond to the multiple blade sets respectively to limit the rotating angle of the blade sets. Two adjacent sets of blades are arranged in an interlaced form. Each set of blades includes a rod, a first blade (34) and a second blade (36). The rod passes through the rotating shaft along its radial direction, and the both ends of the rod are exposed from the rotating shaft to form a first portion and a second portion. The first blade is fixed on the first portion, and the second blade is fixed on the second portion. The first blade is at such an angle with the second blade that the first blade when rotating can drive the second blade to rotate synchronously by the rod.</p> |
