DEVEROPMENT OF AIR INJECTION SYSTEM INTO SEA WATER WITH WAVE FORCE TURBINE AND LINEAR CRANK COMPRESSOR

This paper shows the new machine to generate compressed air automatically by water waves. First, the new hydraulic turbine is devised which is rotating toward only one way by wave forces going and returning with using two one-way ratchet gears. This turbine can work as well as a common water turbine for one way current. Then, a new compressor cylinder is shown having the new crank mechanism converting a rotating motion into a reciprocating motion through a connecting rod moving straightly by employing the hypo-cycloid technique. With installing this compressor cylinder to the devised turbine, compressed air can be generated by water waves. Finally the laboratory experiments have been done to examine how the compressed air can be generated and injected into water automatically by using this mechanical system. From the experimental results, we expect that this mechanism can be applied in fields to generate compressed air for abstraction of natural wave energy and air bubble curtain in sea water for improvements of coastal environment.
