Embodiment

Follow the tracks of the device of solar irradiation, it mainly is made up of battery grillage 1, warp-wise tracking section and broadwise tracking section.Described broadwise tracking section is made up of the circular orbit 6 that has negative slope, orbit centre axle 5 and coaster 3; Described warp-wise tracking section is fixed on the coaster 3 by pin joint 2 by the bottom of battery grillage 1 and forms.

Described broadwise tracking section also comprises damped cylinder 7 that is fixed on the coaster 3 and the working face of fixing annular damping curve 8 in orbit; Described warp-wise tracking section also comprises crank 9 and rocking bar 10; One end hinged securement of described rocking bar 10 is in the chute of crank 9, and the other end is articulated on the battery grillage 1, and control battery grillage 1 makes its normal direction point to the direction of the sun all the time, is used for the illumination of the real-time tracking sun.

The course of work of this device:

1, according to changes of seasons, adjust position in the chute of rocking bar on crank (during summer slightly away from the central point of crank, during winter near central point) adjust battery grillage 1 every day angle of pitch ∠ θ the amplitude of oscillation, with the variation of the sun altitude that adapts to Various Seasonal every day.

2, before dawn every day, fill up the working media in the damped cylinder, open orifice valve, adjust damping coefficient.

3, slide rail one end with coaster is adjusted to the height that is lower than starting point, as the position of terminal point.

4, open the broadwise retaining device of coaster, adjust damping coefficient or track grade at any time, coaster is advanced slowly at the effect lower edge of self gravitation track, the illumination of the velocity of rotation and the sun is synchronous, sets until the sun.

5, remove the broadwise damping action.

6, coaster resets, and makes the coaster that is loaded with the battery grillage get back to original position.Availablely reset jack a bit, coaster is slipped get back to starting point (reduction point) in order to working on tomorrow with the terminal point lifting of track.
