- 堰堤の下部に形成された取水口の上方位置に、堰堤の前方で水面に浮かぶフロートまたは水面よりも上方で堰堤よりも前方に突出するデッキが設置されて、このフロートまたはデッキのほぼ真下に、所定の上下間隔で保持可能なフレームが多段で設けられ、この各フレームには、上側の遮水膜の下端が下側の遮水膜の上端にオーバーラップして取水口の周囲を遮水可能な遮水膜が吊下げられるとともに、最上部のフレームの上方に、蓋付きフレームでなる整流板が配置され、この整流板と最上部のフレームとが一定長さの連結具で連結されることで、整流板と最上部のフレームとの間に取水開口が形成され、この整流板に、上記フロートまたはデッキに取付けられた昇降機のワイヤーが連結されて、昇降機の駆動によって、整流板とともに移動する最上部のフレームとの間の取水開口を所定の取水層内に昇降させることを特徴とする遮水膜昇降式選択取水設備。
- 上記堰堤に、各フレームの端部との間の側部隙間を塞ぐ側部遮水カバーが設けられている請求項1記載の遮水膜昇降式選択取水設備。
- 上記整流板のフレームに、蓋部分と堰堤との間の上部隙間を塞ぐ上部遮水カバーが設けられている請求項1または2記載の遮水膜昇降式選択取水設備。
- 上記整流板のフレームに、蓋部分と堰堤との間の上部隙間を塞ぐ上部遮水カバーが設けられ、この上部遮水カバーは、堰堤の傾斜に倣うようヒンジ結合されて、その自由端部に、堰堤に接触するローラが取付けられている請求項1または2記載の遮水膜昇降式選択取水設備。
