双浮移动离船检测平台的研究及应用

Research and application on the double-floating off-ship detection platform

通航船舶超吃水问题是影响内河航运安全的主要威胁之一,针对困扰内河航运管理的吃水检测难题,创新开发了国内外首套双浮移动离船检测平台并得到了成功应用.本文介绍了双浮移动离船检测平台的总体布置和主要组成;设计了浮式平台支承下保持姿态平稳的刚柔结合的结构型式;通过水下载荷有限元计算和涡激振动仿真,计算出最优化的横杆截面;经过技术对比,研发了基于多个单波束超声波阵列的吃水检测系统;探索了干扰数据修正和误差补偿的数据处理技术.该检测平台实现了通航船舶吃水深度的精确、高效检测,可对通航船舶吃水情况进行实时监控和管理,航运管理部门一旦收到超吃水预警信息,立刻采取措施限制超吃水船舶的通行,保证了内河航运的安全和通畅.

The problem of ships’s ultra-draft is one of the main threats to the safety of inland navigation channel.Focus on the difficulty of draft detection,the first double-floating off-ship detection platform has been developed and applied successfully.This paper mainly introduces the general layout,major components and key technologies of the detection platform.A rigid-flexible supporting structure is designed to keep the stability of detection frame under two floating platforms.The optimum cross section of the detection frame is selected by analysis of loads and vortex-excited vibration simulation,.A draft detection system based on single-beam ultrasonic array is designed.The data processing techniques of interfering data and error compensation are explored.The detection platform can detect the draft depth of ships accurately and efficiently,and can monitor and manage the ships constantly.Once the shipping management department receives the warning information of ultra-draft,it immediately takes measures to restrict the passage of ultra-draft,thus ensuring the safety and smooth flow of inland river traffic.
