Description

Technical Field

[0001] This utility model relates to the field of underwater robot technology, and in particular to the field of underwater cleaning robots. Background Technology

[0002] Currently, underwater cleaning of ship hulls mainly employs two methods: manual divers and traditional mechanical cleaning. Manual divers rely on underwater manual operation, resulting in low efficiency and significant impact from environmental factors such as underwater visibility and current speed. Workers face safety risks including drowning and decompression sickness. Furthermore, the manual cleaning force is difficult to control precisely, easily causing scratches to the hull coating. Traditional mechanical cleaning devices typically have fixed brushes that cannot adapt to the curved contours of the ship's hull, leading to issues such as poor fit and numerous blind spots. Moreover, the single mechanical brushing function is insufficient to effectively remove stubborn marine organisms, leaving residues after cleaning, thus failing to meet the needs of efficient ship cleaning and protection.

[0003] Furthermore, existing underwater cleaning devices generally suffer from insufficient corrosion resistance, susceptibility to entanglement and jamming by marine organisms or impurities, and limited cleaning modes, making them unsuitable for the complex underwater operating environment and diverse cleaning needs of ships. As the shipping industry moves towards high efficiency, energy conservation, and environmental protection, higher demands are placed on the automation, intelligence, high adaptability, and low-damage cleaning capabilities of underwater cleaning devices. Therefore, developing an underwater cleaning device brush that can adapt to the curved surfaces of ships, achieve high cleaning efficiency, possess excellent corrosion resistance, and avoid damage to the hull coating is crucial for addressing current pain points in underwater ship cleaning and promoting the upgrading of ship maintenance technology, possessing significant engineering application value and market prospects.
