Patent ID: 8624418

Claim:
A device for converting wave energy into electricity, comprising: a) a float ( 5 ); b) a guiding-accelerating wheel ( 2 ), the guiding-accelerating wheel ( 2 ) comprising a wheel body ( 201 ) comprising a casing ( 2010 ), a wheel center ( 2011 ), and a chamber ( 208 ); c) an impeller ( 1 ); and d) an electric generator ( 4 ), the electric generator ( 4 ) comprising a rotor ( 402 ); wherein the float ( 5 ) is upward and downward movable in accord with a movement of wave; the guiding-accelerating wheel ( 2 ) is connected to a lower part of the float ( 5 ); the wheel center ( 2011 ) is disposed inside the casing ( 2010 ); a plurality of deflectors ( 2012 ) is annularly arranged between the casing ( 2010 ) and the wheel body ( 201 ), and the deflectors ( 2012 ) are inclined to a same direction; water channels ( 202 ) are formed by the casing ( 2010 ), the wheel center ( 2011 ), and every two adjacent deflectors ( 2012 ), each water channel comprising a water outlet ( 2022 ); the impeller ( 1 ) is clamped on the guiding-accelerating wheel ( 2 ) at a position corresponding to the water outlet ( 2022 ) of the water channel ( 202 ), and the impeller ( 1 ) is movable in relation to the guiding-accelerating wheel ( 2 ); a plurality of blades ( 101 ) is annularly arranged on the impeller ( 1 ); the blades ( 101 ) cooperate with the water outlet ( 2022 ) to allow the water from the water outlet ( 2022 ) to collide with the blades ( 101 ) and drive the impeller ( 1 ) to rotate; the electric generator ( 4 ) is arranged inside the chamber ( 208 ); the rotor ( 402 ) is driven by the impeller ( 1 ); a plurality of vertical anti-rotating boards ( 205 ) is disposed on an outer side of the casing ( 2010 ); a vertical height of the vertical anti-rotating board ( 205 ) is larger than a thickness thereof; a plurality of anti-rotating ear-shaped plates ( 603 ) is disposed on an outer side of a downward pressurizing cylinder ( 6 ); and the vertical anti-rotating boards ( 205 ) are in rigid connection with the anti-rotating ear-shaped plates ( 603 ), respectively.
