WAVE POWER GENERATING APPARATUS

摘要

The present invention relates to a wave power generating apparatus, and has the aim of increasing the efficiency of power generation to the maximum by efficiently using all of the kinetic energy of waves. To accomplish the aim, the wave power generating apparatus of the present invention comprises: a fixed frame (10) fixed in the sea; and one or more power generating units (20) including a movable frame (30) installed on the fixed frame such that the movable frame is movable in the upward and downward directions through the surface (B) of the sea, a buoy (40) mounted on the movable frame (30) in order to float the movable frame (30) on the surface (B) of the sea, an impeller (50) installed on the movable frame to rotate against the waves at the surface (B) of the sea, and a generator (80) which is connected to the impeller (50) to generate electrical energy through the rotating force applied by the impeller (50). The impeller (50) has an impeller shaft (52) arranged so as to be rotatable about a vertical axial line (l) with respect to the surface (B) of the sea; and a plurality of impeller blades (54) fixed along the outer circumference of the impeller shaft (52).
