Currently, pile foundations, such as cast-in-place piles or pipe piles, are commonly used in deserts as the photovoltaic foundation. As shown in fig. 1, taking a conventional 2×13 module arrangement scheme as an example, a photovoltaic foundation adopts a double-upright 5 span arrangement, and 10 pile foundations 300 are provided. Each pile foundation 300 ensures the pulling resistance and the sliding resistance requirements of the photovoltaic foundation through friction force between the pile foundation and the soil layer. Pile foundation 300 requires the cost of drilling and formwork during deployment. After the photovoltaic foundation is used for a period of time, vortex wind erosion is easy to form around the pile foundation 300, so that the depth of the pile foundation 300 embedded into a soil layer is reduced, the bearing capacity of the pile foundation 300 is reduced, and the photovoltaic support and the photovoltaic assembly are possibly damaged.

Through repeated thinking and verification, the inventor finds that if the photovoltaic foundation is arranged into a frame-shaped structure, the photovoltaic foundation meets the pulling resistance and the sliding resistance requirements through the gravity of the photovoltaic foundation, so that the bearing capacity of the photovoltaic foundation is not influenced by wind power, and the reliable operation of the photovoltaic bracket and the photovoltaic module can be ensured. Meanwhile, the cost of drilling and supporting the mold can be saved by using the photovoltaic foundation.

In view of the above, the present inventors have devised a photovoltaic bracket including a photovoltaic base and a plurality of frame bodies mounted on the photovoltaic base, the photovoltaic base being a frame-like structure formed of a first tube and a second tube. The photovoltaic foundation can meet the pulling-resistant and sliding-resistant requirements by filling the counterweight material into the first pipe and/or the second pipe.
