Abstract
This study focuses on a key hydraulic structure in China - the sluice gate - and explores the application of underwater robots equipped with optical imaging technology in safety monitoring. Given that the underwater structure of sluice gates is constantly exposed to water, making them susceptible to corrosion and erosion, the study underscores the necessity of regular safety inspections. The technology of underwater robots utilized in this research effectively addresses disturbances caused by water flow and conducts thorough analysis using high-definition video and image data. The findings reveal that this technology can accurately identify a range of structural defects such as sedimentation, concrete erosion, and cracks, even in low-visibility underwater environments. This discovery confirms the significant potential of underwater robots in enhancing the efficiency of safety monitoring for sluice gates. Overall, the study not only proves the practicality of underwater robots in inspecting the structure of sluice gates but also provides profound insights into the advancement of underwater detection technology and the maintenance and safety assessment of hydraulic facilities.
