Abstract
Description
本発明は、水塊上の表面の波に存在する機械的エネルギを有用なエネルギに変換すること、特にそのような機能を実施する最近開発された装置の改良に関する。
本発明の好適な実施形態では、細長く中立的またはわずかな浮力を示す部材が、水塊の平均水位の下方の選択深さにほぼ直立向きに配置される。細長い部材は中空であり、閉鎖上端部及び開放底端部を有する。その部材は、中空部材内に配置されたフロートに、それに対して垂直方向に移動可能な関係に取り付けられている。部材は、機械的エネルギトランスジューサ、たとえば、油圧シリンダにも固定されて、それにより、通過表面波に応じた部材の垂直移動を有用なエネルギに変換することができる。
本発明に従った装置の全体図が図1に示されている。装置の一定の詳細が、図2及び図3により明白に示されている。図1及び図2は、閉鎖上端部12(図2)及び開放底端部14を有する細長い中空管10が示されている。使用の際、管10は、風で生じる表面波を有する水塊、たとえば海洋内に直立向きに(後述するように)完全に水没する。
