<p>The invention relates to a device for collecting and transforming solar energy into electric and thermal energy. According to the invention, the said device consists of a parabolic mirror (1), which has fixed, in its geometrical focal point, a solar collector (2), which consists of a spherically shaped metallic body, through which there is circulated a thermal medium and which is located inside another spherical emptied body (3) made of glass, the vapours generated in the solar collector (2) being circulated through a turbine (4) which actuates a direct or alternating electric current generator (5), an electric accumulator (6) and, optionally, an inverter (7), as well as a heat exchanger (15) and a pump (16) for pumping the condensed vapours into the solar collector (2), the heat exchanger (15) being, at the same time, a vapour source which drives another turbine (18) for actuating the generator (5), in connection with this turbine (18) there being mounted a condenser (20), and also another pump (19) for pumping the condensed vapours back into the heat exchanger (15), it being also provided with a system of electronic determination of the sun position, consisting of two pairs of photo-elements (8 and 9), located on the circumference of the mirror (1), in order to transmit the tension generated by the luminous flux to a comparator (10) connected to a processor (11) for controlling some servo-mechanisms (12 and 13), for orienting and positioning the mirror (1) so as to collect a maximum of solar energy.</p> |
