Abstract

(57)【要約】 【目的】従来の波力発電は周波数が安定して無かった。
いったん海水を山上の貯水池に揚水することで、周波数
の安定した発電を可能にした。 【構成】波が上がる時に海水を広い取水口で集めて細い
揚水管に送る。波が下がる時に、海水を弁で押さえ、空
気で圧力を抜く。発電そのものはダムによる水力発電と
なんら変わりは無い。

Description

【発明の詳細な説明】 この発明はいわゆる波力発電に関するものである。従来
の波力発電は波の力で直接に発電しているので発電周波
数が安定していない。しかし本発明においては、いった
ん海水を山上の貯水池に揚水するので、発電そのもの
は、従来のダムによる水力発電と、なんら変わりは無
い。具体的に海水を揚水する方法は極めて簡単である。
波が寄せる時に、海水を広い取水口で集めて細い揚水管
に送る。波が下がる時に、弁で海水を押さえ、空気で圧
力を抜く。各ユニットを直列に防波堤状に並べ山上に揚
水する。たったこれだけのことで、我が国の電力は永久
に確保されるのである。
【図面の簡単な説明】
【図１】波が寄せる時である。
【図２】波が寄せる時の正面から見た弁の動きである。
【図３】波が引く時である。
【図４】波が引く時の正面から見た弁の動きである。
【図５】１ユニットの正面図である。
