PROBLEM TO BE SOLVED: To provide a lower layer water circulation device for circulating seawater or lake water or river water in lower layer water circulation means having a lower water discharge opening on a water surface in one end upper part and a resource recovery opening for mining an organic substance resource or an inorganic substance resource in the other end lower part.SOLUTION: A lower layer water circulation device comprises an internal member smaller than water in specific gravity of closing a water discharge opening when an inside water surface is the same as a water surface outside lower layer water circulation means by penetrating through the inside of the lower layer water circulation means. Also, upper air in the lower layer water circulation means is exhausted, and an upper water surface in the lower layer water circulation means is moved to an upper part than the water surface outside the lower layer water circulation means, and the internal member is moved to an upper part in the lower layer water circulation means, and closing of the water discharge opening is made dischargeable. Thereby, seawater or lake water or river water is discharged to the outside of the lower layer water circulation means from the water discharge opening, and lower layer water of the seawater or the lake water or the river water in the lower layer water circulation means is gradually moved to the upper part, and the lower layer water of the seawater or the lake water or the river water in the lower layer water circulation means is circulated.SELECTED DRAWING: None

    【課題】一端の上部に水面上の下部の水排出用開口と、有機物資源又は無機物資源を採掘する資源回収開口を他端の下部に具備する下層水循環手段内の海水又は湖水或いは川水を循環する下層水循環装置を提供する。【解決手段】下層水循環手段の内部を貫通し内部の水面が前記下層水循環手段外の水面と同じである際、水排出用開口を閉鎖する比重が水より小さな内部部材を備え、前記下層水循環手段内の上部の空気を排気し前記下層水循環手段内上部の水面を前記下層水循環手段外の水面より上部に移動させることにより前記内部部材を前記下層水循環手段内の上部に移動させて前記水排出用開口の閉鎖を放出可能にすることにより前記水排出用開口より海水又は湖水或いは川水を前記下層水循環手段の外に放出して前記下層水循環手段内の海水又は湖水或いは川水の下層水を徐々に上部に移動させ前記下層水循環手段内の海水又は湖水或いは川水の下層水を循環する。【選択図】なし
