Qinshan Nuclear Power Completes Overhaul Validation of Grille Cleaning Robotic Arm
The grille cleaning robotic arm, an integrated system of UAV-based intelligent inspection and robotic arm automatic cleaning independently developed by the Mechanical Team of the Fourth Maintenance Division at Qinshan Nuclear Power, recently completed on-site validation during the Unit 2 312 overhaul at Qinshan Phase II. Designed for seawater system intake grille cleaning scenarios, this equipment transforms the original manual operation requiring entry into deep wells into an unmanned operation conducted under ground-based remote monitoring. The intake grille serves as a critical barrier for the cooling water system of a nuclear power plant, and its unobstructed condition is directly related to the stable operation of the unit. In traditional cleaning methods, workers were required to enter narrow shafts more than twenty meters underground to perform inspection and cleaning in confined spaces, which involved high labor intensity, low efficiency, and safety risks such as falls from height...
