三峡电站“体检”用上高科技

Modernization Overview - The annual maintenance of the Three Gorges Dam, referred to as "yearly inspection," is a significant engineering task that involves checking everything from core components to the dam structure and navigation locks [1] - The maintenance process has evolved from relying on experienced technicians to utilizing advanced technologies, including 3D scanners and intelligent equipment for precise repairs [1] - New technologies enable the maintenance team to ensure that repairs are necessary and executed effectively, keeping the dam in optimal condition [1] Technological Advancements - The use of 3D scanning technology allows for the detection of millimeter-level differences in equipment wear [1] - Intelligent equipment can perform precise repairs on large turbine components without the need for disassembly [1] - Robots capable of automatic path planning are now employed for labor-intensive tasks such as cleaning generator rotors [1] Inspection and Maintenance Equipment - Mobile "aerial work platforms" are utilized for inspecting the dam's flood discharge deep hole channels [3] - Detection robots equipped with laser ranging and ultrasonic flaw detection are deployed inside pressure pipes for maintenance tasks [4] - Remote-controlled tracked inspection robots are prepared to operate in the dam's drainage tunnels [4]
