Photovoltaic traffic light capable of guaranteeing generation power

The invention discloses a photovoltaic traffic light capable of guaranteeing generation power, including a support column, poles, a cross bar and a signal light. The poles are arranged at the two endsof the top of the support column. The cross bar is arranged between the tops of the two poles in a traversing manner. The signal light is installed to the side of the cross bar. A rotating device isarranged on the top of the cross bar. A fixed column III is arranged on the top of the rotating device, and the fixed column III is a cavity column. A fixed plate I and a fixed plate II are symmetrically arranged on the two sides in the fixed column III. Chutes are respectively arranged in one side of the fixed plate I and in one side of the fixed plate II. Arc chutes are respectively arranged inthe upper parts of the other side of the fixed plate I and the other side of the fixed plate II, and the bottoms of the arc chutes are respectively communicated with the middles of the sides of the chutes. A rotating shaft II a
