Abstract
【解決手段】棒状の永久磁石2aを有するシャフト部2の下端に連結シャフト10を介してフロート7を接続し、このシャフト部2をフロート7の波動Wによる上下動によって、護岸12から張り出して固定された導電性のコイルを内蔵したコイル部6の中央中空部を挿通して繰り返し上下移動させ、発電装置1のシャフト部2の繰り返し上下移動に対する固有周期Toを発電装置1を設置する海域での所定期間に出現する波の周期、振幅および出現率のデータに基づいて発電量が最大となる周期帯に設定して、電磁誘導によって波動Wの上下動を直接的に電力に変換する。

Claims (2)
- 棒状の永久磁石を有するシャフト部と、該シャフト部が長手方向に移動自在に挿通する導電性のコイルとを備え、前記シャフト部と前記コイルのいずれか一方にフロートを接続して、該フロートの波動による上下動によって前記シャフト部と前記コイルとを相対的に前記シャフト部の長手方向に繰り返し往復移動させて発電する波力発電装置であって、この波力発電装置の前記繰り返し往復移動に対する固有周期が、波力発電装置を設置する海域での所定期間に出現する波の周期、振幅および出現率のデータに基づいて前記波力発電装置による発電量が最大となる周期帯に設定されていることを特徴とする波力発電装置。
- 両端部を開口した筒状体を下端開口部を海中に、上端開口部を海上に位置するように配置し、該筒状体の内部に前記フロートを上下移動自在に浮遊させるとともに、波動による前記筒状体内部の海面の振幅が前記筒状体外部の海面の振幅よりも大きくなる位置に前記筒状体の下端開口部から海面までの浸水長さを設定して固定する請求項1に記載の波力発電装置。
