Apparatus for generating electric power using wind energy where each wind collecting blade has a movable auxilliary plate contained therein

摘要

An apparatus for generating electric power from wind energy is disclosed. The apparatus comprises: a base; a blade device; at least one blade unit; a generator; and a wind collecting unit mounted on the base. The blade device includes an upright rod extending vertically along a pivot axis and has a lower end disposed pivotally in the base. At least one blade unit has a plurality of upright blades connected directly and fixedly to the upright rod such that the blade device is rotatable relative to the base about the pivot axis so as to convert wind energy into a mechanical rotary power output. Each of the blades of the blade unit have opposite first and second side surfaces, and a plurality of first wind-collecting ribs extend vertically from the first side surface, spaced apart from each other such that a wind-collecting space is defined between any two adjacent ones of the first wind-collecting ribs. The wind collecting ribs have a thickness that increases gradually toward the first side surface where the first side surface of each of the blades of the blade unit face the second side surface of an adjacent one of the blades. The generator is disposed in the base and coupled to the lower end of the upright rod of the blade device to convert the mechanical rotary power output into electric power. The wind-collecting unit is mounted on the base and includes a plurality of upright plates angularly equidistant and disposed around the blade device where any two adjacent ones of the upright plates define an inwardly converging wind-guiding channel therebetween. The upright plates of the wind-collecting unit are non-flat so that wind is guided by the upright plates of the wind-collecting unit to blow onto the first side surfaces of the blades of the blade unit of the blade device via the wind-guiding channels in the wind-collecting unit.
