摘　　要：传统水面光伏电站常采用塑料浮体结构,但其强度低、耐久性差、易沉没,因此该文提出了一种面向水面漂浮式光伏电站的复合材料浮体系统。该复合材料浮体圆管采用在UPVC塑料圆管外侧缠包玻璃纤维增强树脂基复合材料(FRP)制成,对其制造安装流程进行了详细介绍,并对其组成材料的力学性能以及UPVCFRP复合圆管的平压和弯曲性能进行了试验研究。综合考量其受力特性和经济性,优选出合理的复合浮体系统。进而,基于双向流固耦合数值模拟方法研究了该浮体系统因风、浪、流作用引起的水动力特性。结果表明,该复合圆管浮体方阵结构具备抵御风、浪、流作用的能力,结构安全可靠,为该浮体系统适用水域环境的选择提供参考。Considering the defects and shortcomings of traditional plastic floating systems such as low strength,poor durability and easy to sink, we present a new composite floating system for floating photovoltaic power stations. In the system, the composite floating tube is made of UPVC plastic tubes wrapped with glass fiber reinforced resin matrix composite(FRP) from outside. The manufacturing and installation process were introduced in detail. The mechanical properties of the materials as well as the flat compression and bending properties were experimentally investigated. The composite floating system was optimized by considering its mechanical properties and economy. Furthermore, the hydrodynamic characteristics of the floating system caused by wind, wave and flow were studied based on a fluid-solid coupling numerical simulation method. The results showed that the composite floating system can resist wind, wave and flow safely and reliably. The study provides reference to the choice of the water environment for the selection of applicable composite floating systems.
