Abstract
Wave energy conversion device (WEC) comprising a means for damping the reactionary motion of a wave energy conversion device to wave motion, which is a cylindrical bellowed elastomeric member that acts under axial compression.
Claims12
A wave energy conversion device comprising:
- (a) a first member capable of movement in response to a wave;
- (b) a second member capable of relative motion with respect to the first member under the influence of a wave;
- (c) a linkage comprising a power take-off device and connecting the first member to the second member and;
- (d) a stabilizing member comprising
- a substantially rigid outer ring arranged substantially concentrically around the first member, and
- a substantially rigid half ring attached at either end to the outer ring and passing over the first member;
- (e) at least one damping means capable of damping the relative motion between the first member and the second member under conditions of extreme waves;
- (f) at least one connecting member connecting the stabilizing member to the damping means;
- wherein the damping means is a cylindrical bellowed elastomeric member which acts under axial compression;
- and
- wherein the apparatus converts the relative motion of the first member and the second member into electrical energy.
