Claims (2)
- 流体の流れの中に壁を用いて水路を作り、その水路において、取水口より断面積を徐々に小さくし、且つ、その先に水力発電機の水車を設け、また、水力発電用の水路の壁の外側に新たな壁を設けて水路を作るが、その水路も取水口より断面積を徐々に小さくし、且つ、その水路における流体の圧力は各部分で、水力発電機へ流れる水路の流体の圧力より低く、また、新たな壁の外側を流れる流体の圧力より高くなるように作られた段階減圧式水路型集水型水力発電装置。
- 四角形状の取水口において、対面する2辺より取水口前方に向けて、三角柱をなすように網の面を張り、網の面にはそれぞれ、流体の流入量を調整する開閉幕を複数以上設け、三角柱の2つの底面に防水幕を設けた請求項1の段階減圧式水路型集水型水力発電装置。
