[0015] The beneficial effects of the utility model are:

[0016] The utility model discloses a raw bamboo photovoltaic bracket, which solves the structural strength and stability problems of raw bamboo materials in marine environments by developing a photovoltaic bracket made of raw bamboo. Traditional photovoltaic brackets usually use materials such as metal, concrete, and plastic, which may have corrosion and structural stability problems in marine environments.

[0017] Durability and anti-corrosion protection: Due to factors such as high salinity and humidity in the marine environment, photovoltaic brackets need to have certain durability and anti-corrosion protection capabilities. The present invention provides a feasible anti-corrosion protection technology, which enables photovoltaic brackets made of raw bamboo to have a longer service life in the marine environment.

[0018] Sustainability and environmental protection: The present invention uses raw bamboo as the main material. Raw bamboo has the characteristics of rapid growth and regeneration, and has relatively little impact on the environment. Under the background of the country's proposal of "replacing plastic with bamboo", the use of photovoltaic brackets constructed from raw bamboo can reduce dependence on traditional non-renewable materials and improve environmental protection.

[0019] Cost-effectiveness: The cost of traditional photovoltaic support materials is relatively high, while raw bamboo, as a common and cheap material, only needs to be processed and treated with corrosion protection before being transported to the site for direct installation. This can significantly reduce the manufacturing cost and raw material cost. The photovoltaic support made of raw bamboo provided by the present invention can achieve cost-effectiveness improvement.

[0020] Coordination of sustainable development: The present invention combines photovoltaic technology with sustainable resource raw bamboo, promoting the coordination of photovoltaic power generation technology and sustainable development. By applying the photovoltaic support of the present invention, the utilization of renewable energy and environmental protection can be better promoted.

[0021] Using raw bamboo to build offshore photovoltaic brackets has the advantages of being environmentally friendly, lightweight and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Specifically, see Figure 1As shown, the top assembly 4 and the bottom assembly 7 are connected via a connecting column, which means that the top assembly 4 and the bottom assembly 7 are connected via an inclined column 2 .

[0041] Specifically, see Figure 1 , Figure 3 , Figure 4 As shown, the upper and lower ends of the inclined column 2 are provided with openings, and the connecting bolts 17 pass through the holes and the openings of the barb bolts 18. The connecting bolts 17 fix the barb bolts 18 to the inclined column 2 through nuts, and the other end of the barb bolts 18 provided at the upper end of the inclined column 2 is connected to the top assembly 4, and the other end of the barb bolts 18 provided at the lower end of the inclined column 2 is connected to the bottom assembly 7.
