针对波浪能供电观测浮标的结构组成,分析其工作原理、运动特性、各系统处的海洋腐蚀环境,将浮标划分成多个海洋污损区域。基于目前的防腐方法和浮标复杂的海洋腐蚀环境,综合考虑成本及施工时效性,提出一种防腐油漆涂层加阴极保护双组合的防腐方法,并进行外加电流阴极保护防腐系统及关键参数的设计。通过数值模拟,确定该系统布置在浮标主浮体侧面可实现较好的防腐效果。最后,提出两种防腐系统位置布置方案。
Abstract
In this paper, a wave energy power observation buoy is divided into different fouling areas by analyzing its working principle, motion characteristics and corrosion environment of each system. Firstly, through considering the current anti-corrosion methods, the complex marine corrosion environment of buoys, cost and construction efficiency, a corrosion protection method combining anti-corrosion paint coating and catholic protection is proposed. Based on which, an anti-corrosion system with impressed current catholic protection and key parameters are designed. Furthermore, numerical simulations are carried out and reveal that better anti-corrosion effect can be achieved by setting the above anti-corrosion system along the flank of the main buoy.
