| 摘要 |
<p>The invention relates to a shaft power plant (1) for generating electricity by converting the energy of a flow between upper water (2) and lower water (6), comprising a vertical shaft (7), the shaft crown (10) of which forms an inlet plane (11), which is parallel to the bed and which extends under the water level (3) of the upper water, wherein the shaft (7) is open at the top and is closed at the lower end of the shaft by means of a bottom (9), a unit (15) comprising a turbine (16) and an electric machine (17), wherein the unit (15) is arranged completely under water in the shaft (7), and wherein the turbine (16) is arranged for vertical water passage, and a drain (24) connected to the turbine (16), said drain providing a closed flow channel and leading to the lower water (6) through a passage (28) in the shaft (7), wherein in a horizontal plane of a turbine rotor (19) of the turbine (16), a first cross-sectional area of the shaft (7) is substantially greater than a second cross-sectional area taken up by the turbine rotor (19).</p> |
