DEVICE USING THE DRIVING FORCE OF VORTEX-INDUCED VIBRATIONS (VIV) EXERCISED ON A WIND-FACING CIRCULAR SECTION PRISM TO TRANSFORM WIND ENERGY INTO ELECTRICITY

摘要

The invention relates to a device using the vertical oscillations undergone by a prism of circular section in an air flow to generate electricity. It consists of a mast (1) in which is inserted an axis (2) on which is fixed a plate (3) which pivots in a horizontal plane. On the plate (3) is fixed the cradle (4), which will support horizontally using four springs (5) the prism of circular section (6). The springs (5) are fixed on one side to the cradle (4), and on the other on the perimeter of the outer faces of the prism of circular section (6). In the center of these two faces are arranged two magnets (8) and opposite these magnets, two rows of three or more copper coils (9), intended to generate electricity. The coils (9) are attached to the uprights of the cradle (4). In order to improve the efficiency of the device, behind the prism of circular section (6) is arranged a prism of rectangular, horizontal and fixed section (10). Finally, fixed to the plate (3) and also to the prism of fixed rectangular section (10), two fins (11) make it possible to orient the entire device facing the wind. The device according to the invention is particularly intended for transforming wind energy and kinetic energy and into electricity.
