[0003] Offshore photovoltaic brackets and photovoltaic power generation component systems are in a marine environment with high humidity, high salinity and long sunshine for a long time, which will cause marine corrosion. In addition, in the marine environment, waves and currents work together to form eddies near the underwater piles and pile legs. The movement of the water body entrains the mud near the pile legs, causing the mud surface to be scoured and the pile legs to be exposed. This causes scour in a larger range and depth near the pile foundation, seriously affecting the stability of the pile foundation, causing the pile body to be eroded faster, and ultimately shortening the service life of the offshore photovoltaic brackets and photovoltaic power generation component systems, and greatly increasing investment and operation and maintenance costs.
