CHU XUANXUAN / LIU QINGCAO / QIAN HONGLIANG / WANG FUMING

The invention relates to an offshore wind generating set pile foundation scouring and corrosion monitoring system and method, the system comprises a data analysis platform and a laser radar arranged on an offshore wind generating set, the laser radar is located above the seawater surface where the offshore wind generating set is located, and the data analysis platform is arranged on the coast; the laser radar is used for detecting the elevation difference between a seabed around a pile foundation of the offshore wind turbine generator set and the surface of the pile foundation at different moments to obtain seabed point cloud data and pile foundation point cloud data at different moments; the data analysis platform analyzes the fluctuation form of the seabed by using the seabed point cloud data at different moments, and analyzes the dynamic evolution condition of the seabed by comparing the differences of the seabed point cloud data at different moments; and analyzing the corrosion condition of the surface of the pile foundation by comparing the difference of the point cloud data of the pile foundation at different moments. The laser radar is used for collecting point data, the laser radar is not corroded by seawater, and the service life of the system is prolonged.

本发明涉及一种海上风力发电机组桩基冲刷与腐蚀的监测系统及方法，其系统包括数据分析平台及设置在海上风力发电机组上的激光雷达，激光雷达位于海上风力发电机组所在的海水表面上方，数据分析平台设置在海岸上；激光雷达用于探测不同时刻海上风力发电机组的桩基周围的海床及桩基表面的高程差，得到不同时刻的海床点云数据及桩基点云数据；数据分析平台利用不同时刻的海床点云数据分析海床的起伏形态，通过对比不同时刻的海床点云数据的差异，分析海床的动态演变情况；以及通过对比不同时刻的桩基点云数据的差异，分析桩基表面的腐蚀情况；本发明通过利用激光雷达采集点位数据，其激光雷达不会受海水腐蚀，提高了系统的寿命。
