摘要:
The invention relates to a runner (2) for a tidal power plant, comprising a hub body (4) provided with openings (40) for receiving blades (10), individual rotating means (8) for rotating each blade with respect to the hub body, around an axis (Y10) that is perpendicular to a rotation axis (X2) of the runner. The rotating means (8) include at least one linear servomotor (14) or an electric motor (22) capable of rotating a corresponding blade (10) independently of the other blades, over an angle superior or equal to 180° around its axis (Y10).
摘要:
The present invention generally relates to hydro turbine. The runner unit according to the present invention allows adjusting the gap clearance downstream and between the runner end tip portion and the inner edge of the blades. This gap clearance may depend on the angular position of the runner blades.

The present invention generally relates to a runner unit (3) of a tidal power plant, and more particular to a device (1) for reversing a blade (2) of the runner unit. The device according to the invention is lighter and more efficient with respect to known solutions which involve articulated mechanisms as it is based on an auxiliary servomotor (6) including a reciprocating linear rack (61) which acts on the blade (2) to be reversed.
