Embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Please refer to Fig. 6 and Fig. 8, Fig. 6 is the solar tracking device heeling condition synoptic diagram that barycenter of the present invention overlaps with rotation center, and Fig. 8 is the solar tracking device horizontality synoptic diagram that barycenter of the present invention overlaps with rotation center.A kind of high-precision sun ability tracker; Comprise the whirligig 2 that is used to install solar cell; Be used to support the column 1 of whirligig 2; And be used for the adjusting mechanism 3 with column 1 fit adjustment whirligig 2, and column 1 is a rotation center 5 with the tie point of whirligig 2, rotation center 5 overlaps with the barycenter 4 of whirligig 2.
For rotation center 5 is overlapped with the barycenter 4 of the whirligig that solar cell is installed 2, a convexity can be set, on the bottom surface of whirligig 2 as the rotation center that is connected with column 1.With respect to the solar tracking device that the barycenter of existing rotating part separates with rotation center, adjusting gear only needs small driving force just can control whirligig to follow the tracks of the sun.
Adjusting mechanism 3 is telescopic linear push rods, and an end of adjusting mechanism is connected in column, and the other end is connected in rotating shaft.Through adjusting this adjusting mechanism, can adjust the anglec of rotation and the sense of rotation of whirligig.Because two-axis solar tracker requires whole whirligig on level and vertical direction, to move; The single-axis solar tracker requires whole whirligig to move in the horizontal direction; So the setting of adjusting mechanism 3 and the known technology that concrete structure is this area, the applicant repeats no more at this.
