[0072] When the orientation of the photovoltaic panel 6034 needs to be deflected to the left, the first servo motor 705 is turned on to drive the winding adjustment rod 701 to rotate, and at the same time, the inner adjustment rod 708 winds up the inner adjustment steel strand 709 to shorten it, thereby driving the left end of the fixed inner frame 602 of the photovoltaic assembly 6 to descend, and the outer adjustment rod 707 loosens the outer adjustment steel strand 709 to lengthen it, so as to facilitate the rise of the right end of the fixed inner frame 602 of the photovoltaic assembly 6, thereby making the fixed inner frame 602 rotate to a suitable angle in the fixed outer frame 601, and the orientation of the photovoltaic panel 6034 deflects to the right;

[0073] When the orientation of the photovoltaic panel 6034 needs to be deflected to the right, the first servo motor 705 is turned on to drive the winding adjustment rod 701 to rotate, and at the same time, the outer adjustment rod 707 winds up the outer adjustment steel strand 709 to shorten it, thereby driving the right end of the fixed inner frame 602 of the photovoltaic assembly 6 to descend, and the inner adjustment rod 708 relaxes the inner adjustment steel strand 709 to lengthen it, so as to facilitate the rise of the left end of the fixed inner frame 602 of the photovoltaic assembly 6, thereby making the fixed inner frame 602 rotate to a suitable angle in the fixed outer frame 601, and the orientation of the photovoltaic panel 6034 is deflected to the right;

[0074] When the photovoltaic panel 6034 needs to be oriented to the left front, the photovoltaic panel 6034 is first adjusted to the left, and then the second servo motor 8010 is turned on to rotate in the opposite direction to engage the transmission wheel 804 on the front side, and the transmission wheel 804 drives the driven wheel 805 to rotate, and the driven wheel 805 rotates to drive the driven worm 806 to rotate, and the driven worm 806 rotates to engage the winding turbine 807, so that the winding turbine 807 drives the winding shaft 808 on the front side to rotate, and the two adjusting steel strands 709 on the front side are wound at the same time, so that the main steel strand 5 gives the slider 4 an oblique downward force, thereby driving the slider 4 to move along the arc track groove 3, so that the photovoltaic panel 6034 is adjusted to the left front.

[0075] When the photovoltaic panel 6034 needs to be oriented to the left rear, the photovoltaic panel 6034 is first adjusted to the left, and then the second servo motor 8010 is turned on to rotate forwardly to engage the transmission wheel 804 at the rear side, and the transmission wheel 804 drives the driven wheel 805 to rotate, and the driven wheel 805 rotates to drive the driven worm 806 to rotate, and the driven worm 806 rotates to engage the winding turbine 807, so that the winding turbine 807 drives the winding shaft 808 at the rear side to rotate, and the two adjusting steel strands 709 at the rear side are wound at the same time, so that the main steel strand 5 gives the slider 4 an oblique downward force, thereby driving the slider 4 to move along the arc track groove 3, so that the photovoltaic panel 6034 is adjusted to the left rear;

[0076] When the photovoltaic panel 6034 needs to be oriented to the right front, the photovoltaic panel 6034 is first adjusted to the right, and then the second servo motor 8010 is turned on to rotate in the opposite direction to engage the transmission wheel 804 on the front side, and the transmission wheel 804 drives the driven wheel 805 to rotate, and the driven wheel 805 rotates to drive the driven worm 806 to rotate, and the driven worm 806 rotates to engage the winding turbine 807, so that the winding turbine 807 drives the winding shaft 808 on the front side to rotate, and the two adjusting steel strands 709 on the front side are wound at the same time, so that the main steel strand 5 gives the slider 4 an oblique downward force, thereby driving the slider 4 to move along the arc track groove 3, so that the photovoltaic panel 6034 is adjusted to the right front.

[0077] When it is necessary to adjust the orientation of the photovoltaic panel 6034 to the right rear, first adjust the orientation of the photovoltaic panel 6034 to the right, and then turn on the second servo motor 8010 to make it rotate forward to engage the transmission wheel 804 on the rear side, and the transmission wheel 804 drives the driven wheel 805 to rotate, and the driven wheel 805 rotates to drive the driven worm 806 to rotate, and the driven worm 806 rotates to engage the winding turbine 807, so that the winding turbine 807 drives the winding shaft 808 on the rear side to rotate, and the two adjustment steel strands 709 on the rear side are wound at the same time, so that the main steel strand 5 gives the slider 4 an oblique downward force, thereby driving the slider 4 to move along the arc track groove 3, so that the orientation of the photovoltaic panel 6034 is adjusted to the right rear.

[0078] It should be further explained that the solar tracker is set as one, which is set on the photovoltaic component 6 in the middle position. The solar tracker is set on the photovoltaic component 6 so that the solar tracker can change direction as the angle of the photovoltaic component 6 changes, thereby making the tracking and monitoring of light more accurate; the solar tracker is connected to the first servo motor 705 and the second servo motor 8010 by wires.
