Abstract
There is provided a free standing tidal power plant without a dam structure set to take up kinetic energy from a water flow. The tidal power plant includes a propeller-shaped water turbine in horizontal rotor configuration with rotor blades, the rotor blades having bidirectional profiles, wherein the rotor blades are fastened to a revolving unit, which defines a rotational plane, and an electric generator at least indirectly driven by the water turbine. Each rotor blade is associated with a first swivel axis and a second swivel axis, the first axis and the second swivel axis extending substantially along a longitudinal axes of a first coupling element and a second coupling element, respectively. The revolving unit includes a planar guide region having a sliding apparatus, a first guide groove and a second guide groove, the sliding apparatus connected to the rotor blade to transmit rotor blade forces.
