Offshore PV Cable Armor Winding and Spot Welding Against Loosening

The patent replaces manual welding operations with an automated welding robot system. The welding robot automatically performs welding at armor gaps, eliminating manual labor while ensuring consistent weld quality and security. This substitution resolves the contradiction by maintaining armor security through automated precision welding while dramatically improving labor efficiency.

The patent implements a self-adjusting armor winding system where the armor winding tension is automatically controlled through a PLC-based closed-loop control system. The system monitors and adjusts winding parameters in real-time, enabling self-service operation without manual intervention for tension control, thereby improving both security and productivity.

The patent applies preliminary reinforcement at armor cut positions by automatically welding reinforcing plates or additional armor segments before the main armor winding process. This preliminary action ensures that the armor maintains its strength at critical cut locations while still allowing the cable to be assembled and configured flexibly according to different installation requirements.

The patent implements localized armor reinforcement at specific cut and weld positions rather than uniformly increasing armor thickness throughout. The system identifies critical locations where armor is cut or welded and applies enhanced protection only at those specific points, maintaining overall armor strength while preserving cable assembly flexibility for different configurations.

The patent replaces traditional mechanical armor winding with an automated winding robot system controlled by PLC. This system precisely controls the winding tension, speed, and positioning, ensuring uniform and secure armor attachment that resists torsional forces. The automated system eliminates the variability and looseness associated with manual or traditional winding methods, maintaining cable protection while significantly improving torsional resistance.

The patent implements a closed-loop feedback control system for armor winding that continuously monitors winding tension, position, and uniformity. Sensors detect deviations from optimal winding parameters and automatically adjust the winding process in real-time, ensuring that the armor remains tightly secured and resistant to torsional forces throughout the entire winding process.
