Claims (3)
- ダム湖等の湖底に係留されて、湖底付近の層の水をエアーレーションにより循環させる曝気装置であって、
前記曝気装置の曝気本体は、外筒と内筒とを備え、下端開口に供給されたエアーレーションとともに内筒内を上昇流が上昇し、上端開口で反転して、外筒との間の下降流路を下降する下降流が出口から排水される構成であり、
前記外筒の頂部と内筒の上端部との間にエアー溜め室が形成されて、前記外筒の頂部には、エアー溜め室の余剰エアーを水中に散気するための散気口が設けられている一方、
上下方向に撓み可能な筒状膜部材を設けて、この筒状膜部材の下端開口縁は、前記散気口を取り囲むように、前記曝気本体の頂部に固定するとともに、前記筒状膜部材の上端開口縁に開口形状保持枠を設けて、水面上に浮上するフロートに設置したウインチを前記開口形状保持枠に連結して、ウインチで開口形状保持枠を上下動させることで、筒状膜部材を開口形状保持枠と曝気本体との間で上下方向に撓ませるようにしたことを特徴とする曝気装置。 - 前記筒状膜部材に内向き折り返し部を形成して、この内向き折り返し部の内部に、筒状膜部材の上下方向の弛みを取るようにテンションを付与する可動式ウエイトを設けたことを特徴とする請求項1に記載の曝気装置。
- 前記フロートは、曝気本体のほぼ真上に位置するように湖底から係留していることを特徴とする請求項1または2に記載の曝気装置。
