Description
本出願は、2015年10月22日出願の、「Hydroelectric Energy Systems, and Related Components and Methods」という名称の米国特許仮出願第62/244,846号の優先権を主張するものであり、これらの内容全体は、参照により本明細書に組み入れられる。
図1を参照して、本開示による水力発電エネルギーシステム100の一実施形態を示す。
水力発電エネルギーシステム100は、ステータ106の半径方向外側に配置されたロータ104 を含む。この配置において、一つ又はそれ以上のブレード(水中翼)101が半径方向内側及び/又は半径方向外側、すなわち回転軸Yに対して内側/外側、に延びることができる。例えば、実施形態の図1を参照すると、半径方向内側に延びるブレード部103と半径方向外側に延びるブレード部102とがある。両ブレード部102、103は流体の流れF(図1中に矢印で示す)内に配置され、それによってロータ104に、中心軸Yを中心とする、ステータ106周りの回転が引き起こされる。種々の実施形態では、複数のブレード101をロータ104の外周面の周りに、例えば外周に均一な間隔で、搭載することができる。
参照として組み入れたPCT/US2015/032948に記載されているように、ステータ106とロータ 104はプラントで製造することができ、製造プラントから設置場所へ、ブリッジ(不図示)及び/又は固定システム(不図示)によって輸送することができる。
