Title:
A WAVE ENERGY PROPULSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/052440
Kind Code:
A1
Abstract:
A wave energy propulsion device for converting wave energy into mechanical energy may
be utilized for electricity generation, booster propulsion or seawater desalination.
The wave energy propulsion device includes a float (1; 10; 1000), a lift connecting-rod
mechanism (2) and a propeller (3; 30; 3000), the float (1; 10; 1000) and the propeller
(3; 30; 3000) are provided respectively on the upper and lower ends of the lift
connecting-rod mechanism (2), the propeller (3; 30; 3000) includes a boxlike
main body which is composed of left and right side walls (31, 32; 301) and cross
links (30; 302) between them, the horizontal projections of the left and right
side walls (31, 32; 301) are linear, the cross link (30; 302) is spanned fixedly
between the left and right side walls (31, 32; 301), the main body has a forward
opening (A), a rearward opening (B), an upward opening (C) and a downward opening
(D), several tilting blades (33; 303) are pivotally installed on the main body,
the tilting blades (33; 303) are composed of foils (331) and horizontal axes(332;
304), the axes (332; 304) are spanned between the left and right side walls (31,
32; 301), the foils (331) tilt up and down around the axes (332; 304), each blade
(33; 303) is equipped with a limitation mechanism for limiting the upper and lower
tilting amplitude (H1, H2) of the back end of the tilting blade (33; 303) to make
the upper and lower tilting amplitude (H1, H2) less than the end tilting length
(L1) of the tilting blade (33; 303). Preferably the lift connecting-rod mechanism
(2) includes two connecting rods (20; 2000) perpendicular to the horizontal plane
and a transmission mechanism. Further preferably the transmission mechanism includes
a front linkage (4000) and a rear linkage (5000), one end of the front linkage (4000)
is fixed on the front end of the float (1000), the other end of that is fixed on the
front end of the main body of the propeller (3000), whereas one end of the rear linkage
(5000) is fixed on the rear end of the float (1000), the other end of that is fixed
on the rear end of the main body of the propeller (3000).
