摘要
随着我国基础设施的不断完善,基建行业的工作重心向检测和养护转移,大批桥梁因长时间的运营和日益增加的交通量,需要进行定期检测以保证结构的使用安全。以水下无人机为载体,搭载摄像、声呐等设备进行水下作业装备的研究受到极大重视,为解决桥梁水下结构的检测问题提供了新的思路和方法。本文就水下机器人在桥梁水下结构检测中的应用进行了论证,阐述了典型应用场景和实例;同时,指出抗流性弱是限制水下机器人发展的一项关键技术瓶颈;并针对这一问题,以运动受力分析为切入点,从多方面展开具体分析,为提高水下机器人抗流性提供了一定的技术指导;最后,展望了强稳定性水下机器人研究和设计的主体方向。
With the constant development of the national Infrastructure construction,the focus of the civil industry has been shifting to the detection and maintenance of existing structures.Many bridges have been in service for a long time with the increased traffic volumes.So regular detection is required to ensure the safe operation of those structures.The multifunctional underwater vehicles equipped with cameras,sonars,and other attachments have paid great attention to underwater operations.Also,that provides a critical idea and method for detecting underwater bridge structures.This paper demonstrates the feasibility of a Remotely Operated Vehicle(ROV)in detecting underwater bridge structures,then expounds on typical application scenarios and examples.Furthermore,considering that the weak anti-current of ROV is the main restriction of its popularization and application,the research on how to improve the anti-current of ROV is discussed in detail based on the kinematic force analysis.Finally,the critical guidance of ROV anti-current technologies is concluded,and the research interests of the high-stability ROV have been prospected.
