Abstract

A hydroelectric generator adapted to be installed in a water course, of the type having a semi-submerged rotor, including a fixed platform, rotor means for the conversion of kinetic energy of a fluid in electric energy, having adjusting means to adjust the position of the rotor means is disclosed. The adjusting means to adjust the position are constrained to the fixed platform and move, in a controlled way, the rotor means with respect to the fixed platform with at least one degree of freedom, to change at least the orientation of the axis (A) of the rotor with respect to the main flow direction (D) of the water.

Claims

1. A hydroelectric generator adapted to be installed in a water course, of the type having a semi-submerged rotor, comprising a fixed platform, rotor means for the conversion of kinetic energy of a fluid in electric energy, comprising adjusting means to adjust the position of the rotor means, said adjusting means to adjust the position being constrained to said fixed platform, and moving, in a controlled way, said rotor means with respect to said fixed platform with at least one degree of freedom, to change at least the orientation of the axis (A) of the rotor of said rotor means with respect to the main flow direction (D) of the water in said water course.

2. The hydroelectric generator according to claim 1, wherein said rotor means are provided with at least one blade having at least in part a spiral development profile along the axis (A) of said rotor means.

3. The hydroelectric generator according to claim 2, wherein said blade is made at least in part of a substantially flexible material.

4. The hydroelectric generator according to claim 1, wherein said fixed platform comprises means for its stable anchoring to the ground.

5. The hydroelectric generator according to claim 1, wherein said at least one degree of freedom comprises the distance of the rotor of said rotor means from said fixed platform.

6. The hydroelectric generator according to claim 1, wherein said at least one degree of freedom comprises the adjustment of the ratio between the volume of the rotor portion of said rotor means submerged in said fluid and the volume of the rotor portion not submerged in said fluid.

7. The hydroelectric generator according to claim 1, comprising adjusting means to adjust the height and/or inclination of said fixed platform with respect to the ground.

8. The hydroelectric generator according to claim 1, comprising adjusting means to adjust the position of said fixed platform in parallel to the main flow direction of the water in said water course.

9. A process for converting the kinetic energy of the water of a water course in electric energy, by means of a hydroelectric generator provided with rotor means for the conversion of kinetic energy of a fluid in electric energy that are moved, with at least one degree of freedom, by respective adjusting means to adjust the position with respect to a fixed platform to which said adjusting means to adjust the position are constrained, said process comprising the steps of:

a. stably installing said fixed platform;

b. adjusting, in a controlled way, the position of said rotor means of said hydroelectric generator at least for orienting the rotor axis of said rotor means with respect to the flowing water and for arranging said rotor means in a position semi-submerged with respect to said fluid.

10. The process according to claim 9, wherein said step of adjusting the position of said rotor means comprises adjusting the distance of said rotor from said fixed platform.

11. The process according to claim 9, wherein said step of adjusting the position of said rotor means comprises adjusting the ratio between the volume of the portion of said rotor submerged in said fluid and the volume of the rotor portion not submerged in said fluid.

12. The process according to claim 9, further comprising adjusting the height and/or inclination of said fixed platform with respect to the ground.

13. The process according to claim 9, further comprising adjusting the position of said fixed platform with respect to the main flow direction of the water in said water course.
