a) Parabolically curved rotating sectors (t) Figs. 1-2-4-5 on which are fixed reflecting material panels (C1), with the same parabolic shape Fig.4. The above said sectors (t) are linked to the carrying structure (T) of the paraboloid (C) by the axes (A) & (a) around which they can rotate:
The rotating sectors (t), as well as being subject to the traction of (m), are also halted by the stops (Ts), placed in a way so that said sectors can rotate only in one direction, when hit by the wind that wins the resistance of (m) Fig. 2a TAV.2.
b) Carrying structure (T) supporting the rotating sectors (t) Figs. 1-2-2a-3-5.
c) Tie rod system (m), Figs 2-5, whose ends are linked steadily: on one side to the carrying structure (T) and on the other one to the rotating sector (t); the above said systems (m), in the absence of strong wind, provide to the systems (t) the initial configuration of the parabolic concentrator (C) Fig.3, for the concentration of the solar rays in the focus zone of the same;
In the presence of strong wind the systems (t) carry out a rotation around the axes (A) & (a) to make the wind flow away so as to reduce the impact with the carrying structure (T); When the strong wind ceases, the tie rod systems (m), force the rotating sectors (t) to return to the starting position, Figs. 2-2a-5.
d) The hinge system (n) Fig.5, can be proposed as an alternative to the axes (A) & (a) on which occurs the rotation of the sectors (t) Figs.1-2-4, so as to claim a).
The ends of the hinge (n) are steadily linked: on one side to the carrying structure (T) and on the other one to the rotating sector (t), Fig.5, so that it can rotate in both ways, around the hinges axes; with this arrangement, the ends of the rod system (m) Figs. 2-5 must be linked differently, between the carrying structure (T) and the one of the sector (t), so as to force the rotating sector (t), in absence of strong wind, to return to the starting position of the parabolic concentrator (C) Fig.3.
