Abstract
Description
図1は、本実施形態に係る波力発電システム1の一例を示す正面図である。波力発電システム1は、岸の近傍に設置され、波エネルギーを電気エネルギーに変換することによって発電する。波力発電システム1は、岸に設けられた波消ブロックの近傍に設置される。波力発電システム1は、建屋2と、波受装置3と、発電装置4とを備える。
図2は、本実施形態に係る波受板100の一例を示す側面図である。図1及び図2に示すように、波受板100は、波力発電システム1において支持装置10に揺動可能に支持される。波受板100は、少なくとも一部に可撓板120を備える。
図3は、本実施形態に係る可撓板120を模式的に示す側断面図である。図3に示すように、第1可撓板121は、岸側(反射波側)を向く前面121Aと、沖側(入射波側)を向く後面121Bとを有する。第2可撓板122は、岸側(反射波側)を向く前面122Aと、沖側(入射波側)を向く後面122Bとを有する。第1可撓板121の後面121Bの少なくとも一部と第2可撓板122の前面122Aとは対向する。第1可撓板121と第2可撓板122とは接続されてなく、別々に撓むことができる。
図7及び図8は、本実施形態に係る可撓板120の動作を模式的に示す図である。図7(A)は、第1の波高の入射波が波受板100に作用したときの可撓板120の動作を模式的に示す図であり、図7(B)は、第1の波高の入射波に基づく反射波が波受板100に作用したときの可撓板120の動作を模式的に示す図である。図8(A)は、第1の波高よりも高い第2の波高の入射波が波受板100に作用したときの可撓板120の動作を模式的に示す図であり、図8(B)は、第2の波高の入射波に基づく反射波が波受板100に作用したときの可撓板120の動作を模式的に示す図である。
以上説明したように、本実施形態によれば、波受板100の少なくとも一部が可撓板120なので、過度な波エネルギーが波受板100に作用したとき、可撓板120が撓む。可撓板120が撓むことにより、波面に対する波受板100の面積(投影面積)が小さくなるため、過度な波エネルギーが波受板100に作用することを抑制することができる。したがって、波受板100又は発電装置4が故障したり破損したりすることが抑制される。機械装置を一切使用せず、波受板100の面積を受動的に変化させることができるため、波受板100の耐久性を低コストで向上することができ、波受板100及び波力発電システム1の性能の低下を抑制することができる。
なお、上述の実施形態においては、可撓板120(第1可撓板121、第2可撓板122)が、前面ゴム板41及び後面ゴム板42を有することとした。前面ゴム板41及び後面ゴム板42の少なくとも一方が省略されてもよい。また、補強材50が省略されてもよい。すなわち、可撓板120は、単層構造でもよい。
