Abstract: As the most important carrier of the floating photovoltaic power plant, the floating body and the connecting block floating body, their structural characteristics are directly related to the Whole poWer plant. Safe operation of the station. In this paper, a new scheme design of floating body and connecting block is proposed. The key points, difficulties and key problems in the design of floating body are analyzed. Through a series of detailed calculation and analysis such as modeling and simulation, the overall stability and reliability of the floating body are demonstrated. Through batch production and processing, it is successfully applied to a floating photovoltaic power station in Anhui Province to float on the water surface. The large-scale construction and use of floating power station has certain reference value.
