| 摘要 |
The subject of the invention relates to a water flow energy converter (40) having a blade wheel (42) suitable for mounting in water flow (W), characterised in that at least two blade systems (82) are arranged on the blade wheel (42), each blade system comprises at least two blade pieces (88) arranged in series, and the at least two blade pieces (88) are mounted on rotation axles (89) that are parallel with the shaft (44) of the blade wheel (42) and are spaced from the blade wheel (42) shaft (44) by different distances such as to allow rotation of the blade pieces (88) around the rotation axles (89) in a first rotation direction (i) with respect to an initial position (A) and to block counter rotation in a second counter rotation direction (j). The invention also relates to such a blade wheel (42). |
