Improved vertical axis water turbine, called hydro-turby.

摘要

The invention relates to an improved vertical axis wind turbine (1), called Hydro-Turby, for, in an inventive and simple way, converting flow energy of water in a stream, river, tide channel and such into electric power, in which the water turbine (1) has at least one vertically shaped rotor body consisting of helix-shaped blades with wing-­shaped cross-section (10) which are located at a constant distance R from the vertical rotation axis (2), in which the rotation axis (2) in its turn drives the generator (3) for generating the electric power, in which the generator (3) is connected to the user by means of a cable, in which the mentioned water turbines (1) can also be used in combination above or below each other for creating more electric power, in which the mentioned water turbines (1) are surrounded by mesh-shaped cage constructions for protection against floating objects in the mentioned water flow.
