Abstract
The invention discloses a method for preventing aquatic organisms from being parasitized on a ship bottom shell. The bionic scaly hull material is manufactured by a novel process, the density of scaly protrusions is 15000-2000 pieces per square meter, and barb type scaly polymeric protrusions are arranged at intervals of 1.5mm at the scaly protrusions to prevent the attachment of larger parasitic organisms. By using the process to build the bottom case, harmful marine parasites such as barnacles can be effectively prevented from being attached, and the maintenance cost of the ship is reduced.
Description
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.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the bionics of this design reference is the pellagoid skin of shark, and the pellagoid biological characteristics are divided into spinous process and basal plate, wherein the spinous process corresponds to the barb-shaped spinous process of the own ship structure, and the basal plate corresponds to the squash-shaped protrusion, as is well known, the difference in skin microstructure between shark and other marine organisms makes the shark unable to parasitize barnacles and other shellfish organisms, and the most important factor except for the fast swimming speed is the pellagoid skin structure of shark, whose surface is rough and extends over the tiny spinous processes, so that marine organisms have no parasitism.
Referring to fig. 2, the bionic fish scale structure and the densely paved scale-like protrusions have a structure in which the number of scale-like protrusions per square meter can reach 15000-.
