Abstract:

Based on summary of advantages and disadvantages of common safety inspection methods, technology and equipment of underwater safety inspection are studied and some solutions are proposed, such as miniaturized high-power ROV, multi-beam combined ROV and intelligent unmanned ships. These solutions have addressed challenges of underwater inspection in complex environment such as deep-buried large-diameter long diversion tunnel, high-head multi-bend penstock and high-flow open water area. Moreover, these technologies have been successfully applied to cascade hydropower stations in the Yalong river basin, which is worthy of reference for similar projects.

Key words: hydraulic structure, safety inspection, ROV, intelligent unmanned ship

摘要: 在总结常用安全检查方法优劣势基础上,重点研究了水工建筑物水下安全检查技术与装备,提出了小型化强动力水下机器人、多波束联合水下机器人、智能无人船等水下检查技术方案,解决了深埋大直径长引水隧洞、高水头多弯段压力管道、高流速开阔水域等复杂环境水下检查难题,并在雅砻江流域梯级电站成功应用。
