CLAIMS 1) Parabolic concentrator (C ) Fig.l formed by a paraboloid divided in rotating sectors (t) parabolically curved Figures 1-2-4-5 covered by reflecting material (CI) Fig. 4 for the captation and the reflection of the solar rays, comprising: a) - parabolically curved rotating sectors (t)Figures l-2-4-5on which are fixed reflecting material panels (CI), 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 axes (A) (a) Figures 1-2-4 are fixed on the sectors (t) in an eccentric way and parallel to the symmetry axes of the same sectors. b) - carrying structure (T) supporting the rotating sectors (t) Figures 1-2- 3-5, so as to claim a). c) - Tie rod system (m), Figures 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, Figures 2-5. 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) Fig: 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) Figures 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 the absence of strong wind, to return to the starting position of the parabolic concentrator (C ) Fig. 3. |
DESCRIPTION TEXT
The parabolic concentrator with parabolically curved rotating sectors (C) Fig. 1, object of the invention, allows to realize concentrators of great dimensions without any reduction of steadiness of the same in the presence of strong wind, and, consequently, the carrying and the movement structures shall be lighter and more economic. The above said concentrators can have a wide application field, especially in those sectors where are needed high temperatures that start from 1000° K to 1300° , for the production of electric power, hydrogen, drinking water and thermoelectric power, adopting respectively: hybrid Stirling motor, fuel cells, steam reformer, desalinators and co-generation systems. Other features are the construction and assembly simplicity of each sector (t); carrying easiness because the concentrator is reducible in sectors.
The invention is described referring to the designs enclosed, Figures 1-2-3-4-5 Tables 1-2 that explain a particular realization of the parabolic concentrator (C) whose components are:
a) parabolically curved rotating sectors (t) Figures 1-2-4-5 on which are fixed reflecting material panels of the same shape and dimension (CI) Fig. 4 Table 2;
b) carrying structure (T) supporting the rotating sectors (t) Figures 1-2-3-5 Tables 1-2;
c) tie rod system (m) (hydraulic and spring...) Figures 2-5 whose ends are linked: on one side to the paraboloid's carrying structure (T); on the other side to the rotating sector (t).
The systems (m) in the absence of strong wind provide to the rotating sectors (t) Fig. 1 the initial configuration of the parabolic concentrator (C) Fig. 3 for the concentration of the solar rays in the focus zone (F) of the same.
In the presence of strong wind, the sectors (t) carry out a rotation around the axes (A) (a) fixed on the same ones in an eccentric mode to make the wind flow away so as to reduce the impact with the plant's structure; when the strong wind ceases the tie rod systems (m) force the rotating sectors (t) to return to the initial position, Figures 2-5 resetting the configuration of the parabolic concentrator (C).
As an alternative to the adoption of the axes (A) (a) for the opening of the sectors (t) can be adopted binges (n) fixed laterally to the same ones Fig. 5, so as in the presence of strong wind, the said sectors (t) can rotate in both ways around the axes of the same hinges (n) by means of a different placing of the tie rod (m) (hydraulic or helical spring...).
STATE OF TECHNOLOGY
To the writers opinion, no parabolic concentrator with parabolically curved rotating sectors with the same technological characteristics has been verified in the present state of technology.
