| 摘要 |
The present invention concerns a structure for converting the energy of a fluid flow into another form of energy, such as a windmill for generating current, said structure comprising: a base, and at least one turbine platform comprising: a ring structure (20) mounted on the base and configured to rotate about an axis with respect to the base, at least two fluid turbines (30, 40) mounted on the platform, each turbine comprising a rotor configured to rotate about an axis perpendicular to the axis of rotation of the ring structure in response to a fluid flow over the rotor, braking means controllable to individually impede rotation of the rotors, the fluid turbines being arranged so that, when rotation of a rotor is impeded by the braking means, the turbine platform is caused to rotate by the force resulting from a fluid flow over the impeded rotor. |
