DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates one application on the ground according to the present invention. There are a sun 11, a solar panel 12 and a holder 14 in FIG. 1.
When the sun move from position P1 to P2, the solar panel 12 will turns from angle A1 to A2 so as to track the sun and maximize the energy collecting from the sun.
FIG. 2 and FIG. 3 illustrate the mounting structure for solar panel according to the present invention. There are a frame 31, two long opening 311,312, a circular opening 313 (showed in FIG. 3), three gears 321,322,323, two bars 341,342, three holders 351,352,353, where the three holders 351,352, and 353 is adjustable.
The frame 31 can fix a solar panel thereon. When the frame turns, the solar panel will turn thereby. The frame has two long openings 311,312 and one circular opening 313. The bar 341 connected to gear 321 works in the long opening 311, and the bar 342 connected to gear 322 works in the long opening 312. The axel of the gear 323 works in the circular opening 313.
FIG. 4 and FIG. 5 illustrate another mounting structure for solar panel according to the present invention. There are a frame 31, two long opening 311,312, a circular opening 313 (showed in FIG. 5), three gears 321,322,323, two disks 331,332, two bars 341,342, three holders 351,352,353, where the three holders 351,352, and 353 is adjustable.
The frame 31 can fix a solar panel thereon. When the frame turns, the solar panel will turn thereby. The frame has two long openings 311,312 and one circular opening 313. The bar 341 connected to disk 331 works in the long opening 311, and the bar 342 connected to disk 332 works in the long opening 312. The axel of the gear 323 works in the circular opening 313. The gears 321, 322 connect to disks 331, 332 respectively. The disks 331, 332 can make a large slope degree to track the sun.
When the gear 323 turns with counterclockwise, the gears 331 and 332 will turn with clockwise so as to seesaw the frame. Certainly, the movement is driven by an AC motor or DC motor. The motor can rotate to turn the gear 323, and then make the gear 321 and 322 turn so as to seesaw the solar panel and track the sun easily. The motor can be set with rotation frequency and rotation clock to meet the tracking requirement. As long as the clockwise turning and the counterclockwise turning are controlled in each 12 hours respectively, the solar panel can produce the maximum performance.
FIGS. 6(A)(B)(C)(D) illustrate the solar panel turns by the gears according to the present invention. The dotted line shows the frame seesaws by the gears 321,322,323.
