[0003] With the transformation of the global energy structure and the rapid development of renewable energy, highways, as important transportation infrastructure, are spread all over the country. The idle areas on the slopes of highways show unique advantages in the deployment of photovoltaic industries. The slopes of highways can be used as ideal places for the installation of photovoltaic modules without occupying additional land resources, making the slopes of highways a renewable energy development model that efficiently utilizes existing space resources, helping to alleviate land shortages and achieve a win-win situation for green development and space optimization.

[0004] The existing highway slope photovoltaic brackets have the defects of poor wind resistance and poor ability to resist slope rain erosion. In strong wind weather, traditional highway slope photovoltaic brackets may be deformed or even damaged due to uneven force, thus affecting the safety and power generation efficiency of the photovoltaic system; in heavy rainfall weather, the highway slopes have complex terrain and loose soil. Heavy rainfall can easily lead to soil erosion in the highway slope area, posing a threat to the foundation stability of the highway slope photovoltaic brackets. The highway slope photovoltaic brackets are easily overturned by slope rain, increasing maintenance costs and safety hazards. Summary of the invention

At the same time, the two adjacent cables are connected by the support brackets to strengthen the lateral connection between cables in different rows, thereby enhancing the integrity and stability of the photovoltaic bracket.

[0009] Furthermore, the base includes a concrete base and a base top plate arranged on the top of the concrete base, and a plurality of reinforcing ribs are fixedly arranged on the top of the base top plate. The contact area between the middle column bracket, the mid-span bracket and the lower end of the anchor assembly and the soil can be increased by the concrete base and the reinforcing ribs, thereby preventing the photovoltaic bracket from being overturned by rainwater on the high-speed slope surface in heavy rainfall weather.

[0017] Furthermore, the photovoltaic panel is fixed on the support bracket and the cable by gluing, and the purpose of installing the photovoltaic panel on the support bracket and the cable is achieved by the action of the glue.

[0018] Through the above technical solution, the beneficial effects of the present invention are: 1. The present invention has a reasonable structure and good use effect, which effectively improves the wind resistance stability of the photovoltaic bracket, can effectively avoid the stress concentration caused by vibration, avoid deformation or even damage due to uneven force, and extend the service life of the photovoltaic bracket; at the same time, it improves the ability to resist rain erosion on the slope, avoids being overturned by rain on the slope surface in heavy rainfall, improves the anti-overturning ability, and reduces maintenance costs and safety hazards.

[0019] 2. The present invention achieves the effect of improving the wind resistance stability of the photovoltaic bracket by installing a mid-span bracket at the mid-span position and installing an oblique support assembly on the mid-span bracket; when the photovoltaic bracket is subjected to strong wind loads acting on the surface of the photovoltaic panel and the photovoltaic bracket vibrates, the bending moment and deformation at the mid-span position of the photovoltaic bracket are the largest, and the damper of the oblique support assembly can effectively absorb the energy generated by the vibration of the photovoltaic assembly, reduce the amplitude of the vibration of the photovoltaic bracket, effectively control the overall torsional vibration and vertical vibration of the photovoltaic bracket, and improve the wind resistance stability of the photovoltaic bracket.

[0020] 3. The support bracket between two adjacent cables of the present invention plays the role of a transverse connection system, which connects the two adjacent cables, strengthens the transverse connection between cables in different rows, and improves the integrity and stability of the photovoltaic bracket. After the photovoltaic bracket vibrates, due to the action of the transverse connection system of the support bracket, the photovoltaic bracket has an equalizing effect on the vibration, so that the vibration amplitude of each part of the photovoltaic bracket is roughly the same, thereby achieving the effect of avoiding stress concentration caused by vibration, avoiding deformation and damage of the photovoltaic bracket due to uneven force, and further improving the wind resistance and stability of the photovoltaic bracket.

[0021] 4. The support bracket of the present invention is composed of two triangular brackets connected to each other, and the triangular bracket is connected to two adjacent cables. The photovoltaic panel can be placed on the support bracket and the cables, and the photovoltaic panel is supported by the support bracket and the cables at the same time. The support bracket increases the contact area between the photovoltaic panel and the photovoltaic bracket, and improves the overall stability of the photovoltaic bracket.

[0022] 5. The present invention installs the base at the lower end of the middle column, the end column and the mid-span column, and by consolidating and burying the base underground, the stability of the middle column bracket, the mid-span bracket and the anchoring assembly can be improved, thereby enhancing the overall stability of the photovoltaic bracket, and further resisting the slope scouring caused by high-speed slope rainwater, ensuring that the photovoltaic bracket is not overturned by slope rainwater during heavy rainfall; the concrete base and reinforced ribs of the base can increase the contact area with the soil, providing better grip for the photovoltaic bracket, so that the photovoltaic bracket can better cope with the hidden dangers of being blown over and the scouring of the photovoltaic bracket by the surface water on the slope in windy weather, thereby improving the anti-overturning ability of the photovoltaic bracket.

[0023] 6. The cross-sections of the center column, end column and mid-span column of the present invention are all square. When the center column, end column and mid-span column are arranged on the highway slope, one of the right-angled sides of the center column, end column and mid-span column can be made to face the slope, so that the two sides of the right-angled side are inclined downward at 45°. When the accumulated water on the surface of the highway slope washes the photovoltaic bracket downward along the slope, the accumulated water will first contact the right-angled sides of the center column, end column and mid-span column. The right-angled sides of the center column, end column and mid-span column will divert the water flow, causing the water to flow along the right-angled sides inclined downward on both sides, thereby further improving the ability of the photovoltaic bracket to resist slope rain erosion.
