A further object of the present invention is to provide apparatus which is adapted to utilize the motion of wave forms in the sea or other open bodies of water and to translate the potential energy in such wave motion into electrical power. It will also be appreciated that a plurality of mechanisms in accordance with the invention may be located close together (or spread over some distance), each generating system operating independently and feeding power into a common electrical grid.
Since in water shallower than twice wave height a wave will normally crest over, surf or break, instead of rising and falling as it does in deeper water, the aforementioned depth at which the frame 5 is located automatically avoids its encountering, and possibly being damaged by, wave cross sections steepened, to crest or surf as above mentioned, due to excessively shallow depth.
For the purposes of this specification the invention will be described with the apparatus located on land and the float in sea water at a location where wave motion is substantially constant. FIG. 2 is a diagramatic perspective view of the motion translation portion of the apparatus. FIG. 4b. Therefore, the accumulator 127 is arranged to store energy during the portion of the cycle b, c, d and f, g, h of FIG. 4b wherein an excess of hydraulic liquid is outputted from cylinder unit 17. The accumulator 127 releases thus accumulated hydraulic fluid to the constant flow valve 128 and the hydraulic motors 129,134 downstream thereof during the portion of the wave cycle wherein the float is stationary or essentially stationary (as at a, h and as at d, e, f).

The system works substantially in the same manner during a falling tide to lower the calm water position of the float 10a. More particularly, a fall in tide causes friction finger 164 to shift the contacts 163a-163c of tide switch downward out of the UP position shown in FIG. As previously stated, the fly wheel 36 is connected to an electrical generating system (not shown) to generate electricity as a result of the downwardly moving masses.

The power generating apparatus which is operated by the vertical movement of the float comprises a vertical elongate support structure 21 immovably fixed in position. The structure 21 carries vertically extending guideways 22 and 23 guiding and supporting a pair of spaced gear racks 24 and 26 which are adapted to move vertically in the respective guideways 22 and 23. Dolor de cabeza por contractura muscular . Each gear rack 24 and 26 is engaged by a gear wheel 27 and 28, mounted for rotation on shafts 32 and 29 on movement of the respective racks.
