[0021] As Figure 2As shown, the free end of the support rod 5 is sleeved with a first torsion spring 10 and a second torsion spring 11, the bottom surface of the photovoltaic panel 6 is fixedly provided with a rotating lug 9, the rotating lugs 9 of the two photovoltaic panels 6 are sleeved side by side at the free end of the support rod 5 and between the first torsion spring 10 and the second torsion spring 11, one end of the first torsion spring 10 is fixedly connected to the support rod 5, the other end of the first torsion spring 10 abuts against the bottom surface of one photovoltaic panel 6, one end of the second torsion spring 11 is fixedly connected to the support rod 5, the other end of the second torsion spring 11 abuts against the bottom surface of the other photovoltaic panel 6, and the two photovoltaic panels 6 are flatly stretched in the free state of the first torsion spring 10 and the second torsion spring 11.

When the wind stops, the torsion spring drives the photovoltaic panel 6 to reset, and under the action of gravity, the rotating column 3 descends to the lower surface of the rotating column 3 coincides with the upper surface of the lamp post 1, so that the photovoltaic panel 6 faces south again.
