AI Technical Summary

Technical Problem

Bird droppings and other dirt accumulate on the surface of buoys in the marine environment, affecting the vividness of the buoy's paint and the efficiency of solar charging. Furthermore, existing cleaning methods are not efficient or environmentally friendly.

Method used

Design an in-situ cleaning device for marine buoys. Utilize an elastic membrane and a tightening rope to form a sealed interface. Combine high-pressure jet rinsing and water jet rinsing, and achieve automated cleaning through a drive mechanism. The cleaning water is recycled to prevent detergent from being discharged into the ocean.

Benefits of technology

It achieves efficient and environmentally friendly buoy cleaning, improves cleanliness and cleaning efficiency, reduces manual labor intensity and environmental pollution, and protects marine ecology.

Abstract

The application provides a kind of offshore buoy in-situ cleaning device, cleaning ship and cleaning method, belongs to the technical field of navigation mark cleaning, for solving the problem that the surface of buoy will gather bird droppings and other dirt, affecting the navigation function of buoy. Among them, the cleaning device covers and cleans the buoy from top to bottom, including connecting base, cleaning barrel and tightening rope; the cleaning barrel is rotatably connected to the lower side of the connecting base and can be driven to rotate by the driving mechanism; the cleaning barrel has no barrel bottom, the barrel shell is provided with first reinforcing structure and second reinforcing structure along the generatrix and circumferential direction respectively, the inner side of the barrel shell is provided with first cleaning structure, the bottom of the barrel shell is rotatably connected with barrel bottom ring, the barrel bottom ring includes two layers of barrel bottom ring shell and elastic membrane, and the elastic membrane is located on the inner side; the tightening rope is arranged in the interlayer between the barrel bottom ring shell and the elastic membrane, after the cleaning barrel covers the buoy, the tightening rope is tightened, and the elastic membrane is tied around the outer periphery of the buoy. The device combined with the matching method has superior cleaning effect and significant environmental protection significance.
