<p>The mechanism of solar tracking mechanism is employed in relation with a solar energy captivation system. The captivation system includes a light reflective cover, with a shape to focus solar radiation over a segment of radiation absorption from a tube that carries a heat transference fluid. The cover is mounted by pivot over a support structure. An actuator mounted between the support structure and the cover moves in a rotatory way the cover. A solar sensor mounted inside a visor tube fixed to the cover, so that the visual line through the visor tube is at least parallel to the optic axis of the cover. The solar sensor generates a sensor signal used as a control inlet for a control system of the actuator. Limiting switches generate end thrust block signals when the cover reaches maximum angular positions. The actuator control system generates fluid flows in the actuator according to the solar sensor signal and to the end thrust block signals. The sun tracking method includes providin g an arrangement of solar cells, actuating the solar captivation system when the solar radiation that illuminates the arrangement surpasses a predetermined threshold value, providing a solar sensor protected against solar radiation, except from direct radiation, aligned, turning with pivot the cover to the west, according to the signal of the solar sensor, stopping the cover in maximum angular positions and turning the cover to the west if the cover does not reach the maximum angular orientation to the west, during a predetermined period of daylight. The solar energy captivation can also be configured to include a bisected cover joined by means of hinges. The cover halves can be folded one against the other to protect the light reflective surface and the radiation absorption segment, of the tube that carries the heat transference fluid. The most representative figure of the present invention is figure number 1.</p> |
