A WAVE POWER APPARATUS HAVING AN ARM CARRYING A FLOAT, AND A PAIR OF BEARINGS FOR SUPPORTING THE ARM

摘要

A wave power apparatus has at least one arm (122), the arm being rotationally supported at one end by a pair of pre-stressed, essentially slack-free bearings (142) and carrying a float (124) at its other end, so that a translational movement of the float caused by a wave results in rotation of the arm. Power conversion means convert power transmitted from the wave to the arms into useful power. The bearing may comprise a flexible material (149) of flat spring (342; 352; 362; 372; 374) allowing rotation or wriggling of the arm (122) around a supporting shaft (126). The apparatus may comprise a plurality of arms, which are supported by individual pairs of bearings.
