Description

A device for removing attachments on the surface of a hydrofoil structure

technical field

The invention relates to the field of hydrofoil cleaning, in particular to a device for removing attachments on the surface of a hydrofoil structure.

Background technique

After the ship is launched for a period of time, due to the strong corrosion of seawater and the tenacious adhesion of marine organisms, not only a large number of barnacles and rust spots will adhere to the surface of the hull, but also a large amount of attachments will adhere to the surface of the hydrofoil used to drive the ship. Their existence not only accelerates the corrosion of the hydrofoil, but also increases the resistance of the ship, increasing unnecessary power loss. As far as the current technology is concerned, although it is effective to inhibit the adhesion of marine organisms by coating, the pollution of the marine environment is very serious and the cost is extremely high; at the same time, regular repairs in the dock are expensive in terms of time and funds huge. Adopting the underwater clearing device can make use of the underwater clearing of the hydrofoil at any time during the berthing of the ship, without affecting the normal navigation of the ship, and can also save considerable time and money.
