The present invention essentially consists of a turbine that has rotary concave blades (11) and can be mounted in the stream of a river bed for producing energy. The system can comprise maximum six hexagonal helices, which is the most suitable shape for better capturing the force of the current of the river stream, such that the movement of the helix does not hinder turbine rotation, increasing on the contrary the speed of rotation when immersed into or emerging from the water. The helices are mounted on a rotation shaft having at the ends thereof a male pinion (12) that is connected to a female pinion (13) arranged inside a speed reduction gearbox. Multiple turbines can be provided, depending on the motive force of each water stream, and can be connected to two current generators arranged one on each side, ensuring that the force impinging on the turbine is regular and balanced. |
