DEVICE AND METHOD FOR PROTECTING A WIND GENERATOR IN THE EVENT OF VIOLENT WINDS AND WIND GENERATOR PROVIDED WITH SUCH A DEVICE

摘要

A device making it possible considerably and remotely to reduce the diameter of the rotor of a wind generator (1) includes a connecting piece (5) connecting the blade (6) to the hub (4) of the wind generator (1), the central axes (B1-B2) of the respective ends (5.1-5.2) of which components form a certain angle (α), the end (5.1) is able to rotate about its central axis (B1) causing the blade (6) to pivot and once the blade has pivoted it is inclined toward the nacelle (3). When the blade (6) is inclined in this way, the connecting piece (5) and the rotor are immobilized, forming the position in which the wind generator (1) is protected. The device is intended to allow optimum and safe operation of the wind generators in regions subjected to violent winds.
