WATER CURRENT TURBINE ROTOR COMPRISING AT LEAST ONE BLADE THAT CAN ROTATE ABOUT A RADIAL AXIS AND MEANS FOR LIMITING THE ROTATIONAL MOVEMENT OF SAID BLADE, AND WATER CURRENT TURBINE COMPRISING SUCH A ROTOR

摘要

The invention relates to a rotor for a water current turbine, which can be rotated by a stream of liquid. The rotor comprises an inner ring, an outer ring and at least one blade (24) that extends between the inner ring and the outer ring along a radial direction (R), said inner and outer rings being centred on a single longitudinal axis (X). The rotor comprises at least one radial shaft (26) extending radially between the inner ring and the outer ring, and at least one blade (24) can rotate about its corresponding radial shaft (26). The rotor (14) also comprises means (28) for limiting the rotational movement of said at least one blade (24) about its corresponding radial shaft (26).
