摘要
鉴于传统水面光伏电站用塑料浮体结构具有强度低、耐久性差、易沉没等缺陷和不足,本文提出了一种面向水面漂浮式光伏电站的复合材料浮体结构。在UPVC塑料圆管外侧缠绕成型玻璃纤维增强复合材料,设计并制造出了一种新型UPVC-FRP复合圆管浮体,对其制造安装流程进行了介绍,并进行了静载浮力分析。运用流固耦合数值分析方法,研究了复合圆管浮体结构因风、浪、流作用引起的水动力特性。结果表明,最大吃水深度为0.346 m,满足浮体对荷载组合下静载的浮力要求,且复合圆管浮体结构方阵具备抵御风、浪、流破坏作用的能力。
In view of the defects and shortcomings of the traditional plastic floating system,such as low strength,poor durability,and easy to sink,etc,this paper presented a new type of composite floating system for photovoltaic power station.A new type of UPVC-FRP composite tube floating system was designed and manufactured by using glass fiber reinforced composite material and UPVC plastic tube combined with hand paste forming process.At the same time,the process of manufacturing and installation was produced,and the buoyancy of static load was analyzed.By adopting fluid-solid coupling FEM,the hydrodynamic characteristics of UPVC-FRP composite tube floating system caused by wind,wave and current were studied.The reliability of the FEM in this paper was verified.The results showed that the maximum draft depth was 0.346 m,which meet the buoyancy requirements of floating body under static load combination.In addition,the composite tube floating system square array can greatly improve the effect of the floating system against wind,wave and flow damage.
