| 摘要 |
The invention relates to a system for generating electrical energy from water currents, such as in particular tidal currents, comprising at least one elongate unit (10) with at least three floating bodies (12, 13a, 13b) provided beside each other and parallel to each other in a row so as to enable the system to float on a water surface of a water reservoir such as a sea, an ocean, a river or the like. The system further comprises a frame (1 1) extending along the length of the elongate unit, of which the at least three floating bodies form part or to which they are at least connected, at least two turbine units to be driven by water currents, each comprising at least one rotor body (32), connecting means (34; 134) for mechanically connecting each one of the at least two turbine units to at least one of the at least three floating bodies and/or to the frame, such that the rotor bodies are positioned completely under the water surface and, viewed from above, between two adjacent floating bodies, connecting means (38; 44) for connecting the system to at least one anchoring means (40) that is connected to the bottom of the water reservoir, the connection being such that the at least one unit can move along with movements of the water surface such as for example caused by wave motion and tidal movement. The system comprises a number of interconnected units arranged in line with each other. The invention also relates to a bridge comprising such a system. |
