波浪荷载作用下水上太阳能复合材料浮体系统受力分析

Force analysis of underwater solar composite floating body system under wave load

针对传统聚乙烯、聚氯乙烯等浮体结构强度低、耐久性差、抗风浪能力差、后期维护成本高等问题,该文提出一种水上太阳能光伏发电复合材料浮体结构。该结构包括采用真空导入成型工艺制备的浮体主梁、次梁以及采用拉挤成型工艺制备的竖向支撑等构件。该文对结构进行了静载浮力、风力受力分析、浮体结构波浪浮力计算以及浮体系统强度校核。结果表明,河流最大水深在5.06 m以内时,浮体主梁所受最大向上波浪浮力压强为50 kPa,复合材料浮体系统主梁满足波浪荷载作用下的承载力要求,且浮体系统具有抵抗波浪破坏的能力,这为之后复合材料浮体结构应用于漂浮式光伏电站提供了参考。

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.
