Abstract: Aiming at the problems of low strength, poor durability, poor wind wave resistance and high maintenance cost of traditional floating structures such as polyethylene and polyvinyl chloride, a floating structure of composite materials for water solar photovoltaic power generation is proposed in this paper. The structure includes the main beam and secondary beam of the floating body made by vacuum induction molding process, and the vertical support made by pultrusion molding process. In this paper, static buoyancy, wind force analysis, wave buoyancy calculation and strength check of floating body system are carried out. The results show that when the maximum water depth of the river is less than 5.06 m, the maximum upward wave buoyancy pressure on the main beam of the floating body is 50 kPa, the main beam of the composite floating body system meets the requirements of the bearing capacity under the wave load, and the floating body system has the ability to resist the wave damage, which provides a reference for the future application of the composite floating body structure in the floating photovoltaic power station.
