Technical Field

The invention discloses a method for preventing aquatic organisms from being parasitized by a ship bottom shell, which is characterized in that a special ship bottom shell with a bionic scale structure is produced by a manufacturing process, and super-hydrophobic coating is sprayed for reducing drag, so that the parasitism of organisms such as barnacles, mussels, oyster and the like can be effectively prevented, the sailing water resistance of a ship can be reduced, and the integral sailing speed is improved.

Background

In the use process of the ship, a large amount of aquatic organisms are attracted to attach no matter in static berthing or dynamic navigation, the attachment of the attached organisms is obviously different according to different water immersion parts of the ship, the waterline parts mainly comprise algae and barnacles, and the attachment speed is higher. The bottom part of the ship mainly comprises shells and mollusks. Mollusks often attach themselves when the seawater temperature is low.

The attachment of marine organisms can cause immeasurable loss to the ship, the ship body and the lower drainage pipe of the ship are integrally influenced, and a large amount of marine organisms attached to the ship bottom can obviously increase the navigation resistance, reduce the navigation speed and increase the fuel consumption.

At present, the general prevention and removal mode is ship docking, tools, a high-pressure cleaning water gun and the like are used for removing, and then antifouling paint is coated before the ship is launched, so that the work is extremely complicated, and a factory, a coating station, a monitoring and repairing room and the like perform cooperative work and waste a large amount of time.

Disclosure of Invention

The invention relates to a novel specially-made bottom shell, which is characterized in that the surface structure of the bottom shell is improved and processed by using a bionic theory, and the specific mode is as follows:

the manufacturing process of the spike-shaped structure on the surface of the hull bottom shell comprises the steps of firstly manufacturing a titanium alloy plate of the whole hull bottom, modeling closely-paved scale spikes and barb-shaped spikes required by the hull bottom through pre-3D modeling software, and setting the work of a welding and guiding machine

Furthermore, the micro-finishing welding is carried out through a welding and guiding machine, and the two bionic spikes are welded on the bottom shell plate material at extremely high density.

Further, cleaning the surface of the newly-made ship bottom shell, spraying low-surface-energy coating, and making a surface super-hydrophobic coating layer.
