Embodiment Construction

[0021] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0022] Such as Figure 1-4As shown, the treatment method includes the following steps: 1) When the main engine of the ship is started, use a heating device to heat the outer surface of the hull to make it difficult for marine organisms to attach to the hull, and the heating device is arranged on the inner surface from the bottom of the ship to the draft of the hull; 2 ) When the ship starts running, a movable hydrofoil structure 2 is arranged on the bottom of the ship, and the hydrofoil structure is initially located on the front side of the bottom of the ship, and the hydrofoil structure includes a hydrofoil plate 2.1, a movable connecting rod 2.2 and a hydraulic dr...

Abstract

The invention relates to a treatment method for preventing fouling on the surface of the hull. Aiming at different biological attachments attached to different draft parts of the hull, different treatment methods are adopted at different parts of the hull, that is, the cabin is used from the bottom of the hull to below the waterline of the hull. The internal main engine and boiler exhaust heat the outermost bulkhead of the hull, making it difficult for marine organisms to attach in a high-temperature environment; and below the waterline, by setting sliding hydrofoils, the hydrofoils slide from the bow to the stern before the ship moves. , to remove marine organisms under the bottom of the ship; the hull surface fouling treatment method adopts different treatment methods for the attachment methods of different parts of the hull, which greatly improves the treatment efficiency and reduces the maintenance time of the ship's docking and undocking, so as to ensure that the Clean up the attachments on the hull in real time during driving.

Description

technical field [0001] The invention relates to the field of removal of marine biological attachments on ship hulls, in particular to a treatment method for preventing fouling on the surface of ship hulls. Background technique [0002] When a ship sails at sea, a large number of marine organisms tend to attach to the hull. If it is not cleaned up in time, it will cause a large amount of marine organisms to accumulate, which will greatly increase the water flow resistance of the hull when the ship is sailing, and the fuel consumption will also increase significantly. The flexibility of the ship is also greatly weakened, and these sea creatures will also accelerate the corrosion rate of the hull. In addition, there are currently three ways to remove attachments from the hull. One is repaired in the dock; the other is by setting a conductive layer or heating layer on the surface of the hull; the third is cleaned by underwater robots. And the above method also has great disadv...
