Marine garbage not only affects the health of marine ecology and hinders the waterway, but also seriously restricts the development of tourism and aquaculture in coastal cities, causing huge social and economic losses. However, the current marine garbage salvage and treatment technology is still not mature enough, and there are pain points such as complex mechanical structure and single function, low intelligence, low efficiency, and high energy consumption. This work has designed an integrated equipment ship for marine environmental management based on multi-sensor fusion. It realizes functional integration through visual self-positioning, efficient gathering and salvage, step-by-step dehydration and corrosion prevention, and automatic monitoring and storage. It can salvage about 1200-1400kg of marine garbage per hour, which greatly improves the work efficiency compared with the existing equipment. In view of the characteristics of some marine garbage such as large water content, perishable and broken, as well as the separation of fishing and dewatering processes, low working efficiency and incomplete fishing and further pollution of the environment, this equipment can carry out efficient and rapid fishing and real-time compression dewatering, thus greatly improving the fishing efficiency of marine garbage. Dehydrated marine garbage is light and non-perishable, thus increasing the loading capacity of the equipment hull and saving the energy consumption of hull, also conducive to the production and utilization of Enteromorpha prolifera. The equipment is integrated into the concept of "digital and intelligent", and the salvage system is automatically identified through machine vision, which improves work efficiency, saves manpower and material resources, and effectively improves my country's emergency response capabilities in marine environmental protection and safety neighborhoods. In addition, the equipment nylon fiber salvage mesh plate and conveyor belt combination technology can be extended to marine garbage salvage management and other problems.
