when the rotating rod is not provided with the counterweight ball, the upper surface of the floating body is just in a horizontal plane state;
when the counterweight ball is tied on the rotating rod, the counterweight ball on the sliding channel can cause the center of gravity on the floating body to shift because the sliding channel is positioned on the periphery side of the central line of the floating body, namely the upper surface of the floating body can incline to the position where the counterweight ball is positioned;
when the counterweight ball slides in the sliding channel, the gravity center of the floating body can also change along with the sliding of the counterweight ball, and the cycle is set to be one day, and the photovoltaic module on the upper surface of the floating body is just enabled to continuously keep facing the sun by setting the initial position in the morning; the counterweight ball can be made of metal, lead with high density in metal, iron with low cost, stainless steel which is difficult to rust and the like.
