<p>A power station for utilising the energy in a flow of water (3) flowing mainly horizontally. During operation, the power station is functioning by means of a rotor (2;16) completely or partly submerged and in form of a shaft (6;18) having a number of projecting blades (7;19) and disposed rotatably around a rotation axis mainly transversely to the flow direction. The power station comprises a blade guide (8;20) for each blade extending mainly radially and serving for displaceably accommodating the respective blade (7;19), and means for displacing the blade (7;19) in such a way in its blade guide (8;20) that its peripheral outer edge will describe an enveloping face (12;27) during every rotation of the rotor (2;16) said face having a minimum distance from the rotation axis (1;15) in an intersection line (28) between this face (12;27) and a symmetry plane (29) extending transversely to the direction of flow. Thereby, a simple structure is obtained that is able to optimally utilise the energy in a flow of water. The power station functions effectively in submerged state in a horizontally flowing flow of water (3) whether the flow is coming from one side or the other of the rotor (2;16).</p> |
