Photovoltaic power generation is a green and clean renewable energy source, and is expected to become an important way for replacing fossil energy in the future in China. The distributed photovoltaic power station is built in a mode that a user side automatically uses electricity and residual electricity is on line, and the distributed photovoltaic power station is a photovoltaic power station form which is widely applied due to the flexible operation mode. Distributed photovoltaic power plants are usually built by relying on roof surfaces of large complexes, warehouses, plants, houses and the like, and photovoltaic systems are arranged on the roof surfaces. The photovoltaic system comprises a photovoltaic assembly and a photovoltaic bracket, wherein the photovoltaic bracket comprises a rod-shaped or plate-shaped base, a vertical rod bracket which is vertically fixed on the base, and an inclined rod bracket of which one end is connected with the base and the other end is connected with the upper end part of a vertical rod; the photovoltaic module is arranged on the diagonal rod bracket. The photovoltaic system has the characteristics of light dead weight and large windward area, so that wind load becomes the main external load of the photovoltaic system; in addition, in order to make the photovoltaic board can receive the biggest illumination radiation, photovoltaic module generally need be equipped with certain contained angle with the horizontal plane, has certain contained angle between down tube support and the base promptly, and this kind of arrangement form has further increased the effect of wind load.

The existing photovoltaic support is divided into a fixed type and a movable type. Fixed photovoltaic support generally can not change the use scene after the installation, so usually adopt the concrete briquetting as the counter weight or through chemical bar planting or expansion bolts mode with the base be connected with original roofing. The movable photovoltaic support needs to be provided with universal wheels under the base (or directly at the lower end part of the support), but the support system has light dead weight, does not have wind resistance, is difficult to resist the wind load, and is only suitable for the environmental condition with small wind load. Fixed photovoltaic support also can remove when adopting concrete buttress structure as the counter weight, when needing to remove photovoltaic support, removes concrete buttress earlier and adjusts the support position again. However, the concrete buttress counter weight has the following defects: 1. the concrete buttress needs the steps of formwork erecting, reinforcing steel bar binding, pouring maintenance and the like, and is time-consuming and labor-consuming; 2. the concrete buttress is heavy in self weight and inconvenient to carry for the second time; 3. because the configuration of the photovoltaic support is mostly according to the wind load technology under the specific condition, the condition changes after the movement, which may cause the lack of the counter weight, but the counter weight cannot be adjusted at the moment, so that the structural system of the photovoltaic support is more unsafe.
