Problems solved by technology

At present, by adding an effective degradable coating to the bottom shell of the ship, the attachment of marine fouling organisms can be significantly inhibited, and there is no pollution. However, the biggest problem is that the effective degradable coating is very easy to degrade and lasts for a short time. Longer ships cannot guarantee anti-fouling effects throughout the voyage
[0006] At the same time, the coating will increase the weight of the ship, which will increase the resistance of navigation, which will lead to an increase in fuel consumption.

Abstract

The invention relates to the technical field of ships, in particular to a ship protection structure and a construction method. The ship comprises a ship body, and the ship protection structure comprises a protection layer arranged on the outer surface below a waterline of the ship body; and magnetic blocks for generating a magnetic field are distributed in the protective layer. According to the invention, the magnetic blocks capable of generating the magnetic field are distributed in the protective layer; the magnetic field generated by magnetism and diamagnetism generated by water under the action of the magnetic field are utilized; however, due to the interaction of forces, the reaction force (lifting force) can be generated on the ship and the sailing resistance of the ship can be further reduced; meanwhile, the main composition of the marine fouling organisms is also organic matters and the organic matters also have diamagnetism, so that the magnetic blocks of the magnetic field generated by the protective layer can greatly reduce the attachment of marine fouling organisms and ensure the navigation effect, and the interaction between the magnetic blocks and water can further reduce the navigation resistance of the ship and improve the transportation capacity of the ship.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship protection structure and a construction method. Background technique [0002] Marine fouling organisms, also known as marine fouling organisms, are animals, plants or microorganisms that attach to the bottom of the hull and various equipment in the ocean, such as diatoms, barnacles, oysters, mussels, etc. [0003] The bottom of a ship without special protection soaked in seawater for a long time usually gathers a large number of marine organisms. The researchers call this phenomenon marine biofouling, and these organisms that grow or attach to the hull of the bottom of the ship are marine fouling organisms. Every year, marine biofouling at home and abroad will lead to major losses. For example, marine biofouling will greatly increase the navigation resistance of the hull and sharply reduce the navigation speed, thereby greatly prolonging the cargo transit period and the dock...
