<p>PROBLEM TO BE SOLVED: To activate the circulation of water up and down in the whole of a lake by forming a funnel-shaped body protruding on the lake surface by a float, installing a pipe of length of reaching the lake bottom on the small diameter side of the body, and using an anchor and fixing the funnel-shaped body on the lake bottom so that the body is not dropped. SOLUTION: A funnel-shaped body 1 is fixed on the lake bed B by an anchor 4 in a manner of setting a large diameter section of the body facing upward by a float 2 so that the body is set a little higher than the lake surface A. When waves C run over the large diameter section and water is infiltrated therein, the funnel-shaped body 1 is sunk downward by the external pressure, passed through the inside of a pipe 3 and sunk down gradually to the lake bottom B. Water is infiltrated into the funnel-shaped body 1 when the waves are risen, and the body is sunk to the lake bottom B. Lake water can be circulated easily by repeating the above-mentioned operation almost without any running cost thereof.</p> |
