Apparatus for converting wind energy into mechanical energy for generating electricity. A bladed wheel 7 is mounted freely rotatably on a pillar 1 and has a number of radial blades 8 which are positioned with interspaces along the circumference of the wheel. A turbine 9 is mounted on the pillar 1 and can rotate freely about the axis of the pillar. The turbine surrounds and is radially positioned at a distance from the pillar. The turbine has a number of blades 10 which are positioned with interspaces along the circumference and are arranged longitudinally in relation to the pillar. Preferably, an annular body 14 is supported by the pillar, and the body has an upper surface 17 with a shape which contributes to a laminar flow of the wind across the surface. Over an upper part of its length immediately below the bladed wheel 7, the pillar preferably has some spiral fins 4 positioned peripherally with a mutual spacing, so that they delimit passages 5, by means of which the wind is forced to flow upwards in the passages to form an eddy. Peripheral, spaced blades 16, which are suspended from the annular body 14, delimit, between adjacent blades, venturi inserts, by means of which the wind is directed towards the blades 10 in the turbine 9. The apparatus makes it possible to achieve better utilization of the wind, even during storms. <IMAGE> |
