Wind detection apparatus which comprises: a fixed support structure (2) provided with a support rod (3) to which a rotatable frame (4) is pivoted in an idle manner; a signaling body (8) with tubular form fixed to the rotatable frame (4) and on which the wind is susceptible of acting in order to rotate the rotatable frame (4) until the signaling body (8) is aligned with the direction of the wind; an illuminating device (17) fixed to the rotatable frame (4) and actuatable to illuminate the signaling body (8); at least one transformer (19), which comprises a primary winding (21) fixed to the support rod (3) and a secondary winding (23) fixed to the rotatable frame (4), and is adapted to transfer the electrical energy between power supply means (18) fixed to the support structure (2) and control means (20) mounted on the rotatable frame (4) and adapted to control the operation of the illuminating device (17). |
