Problems solved by technology

However, this move is accompanied by marine pollution. As the environmental protection departments of various countries pay more attention to antifouling paints that cause marine pollution, antifouling paints are gradually being banned or restricted.
[0005] The traditional cleaning method is to hoist the ship after the ship enters the dock, clean it with chemicals or manually beat the corrosion scale with simple utensils. There are many shortcomings in this method: 1) only waiting for the ship to enter the dock The cle

Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] The present invention adopts a brand-new design idea from the system design. The system adopts the idea of ​​modular design, which divides the equipment into multiple modules, which greatly improves the reliability and easy maintenance of the system.

[0018] Such as figure 1 As shown, the underwater cleaning equipment for the large ship bottom is composed of three parts: the monitoring and control unit on the ship, the underwater cleaning unit and the connecting cable. The on-board monitoring and control unit is operated by the on-board staff. It is mainly composed of a display 3, a controller 2 and a key input module 4. It has image monitoring, underwater cleaning unit status monitoring and underwater cleaning unit control functions. The on-board monitoring and control unit controller 2 adopts the controller with Cortex...

Abstract

The invention provides a bottom underwater cleaner for large vessels. The bottom underwater cleaner for large vessels comprises an on-board monitoring and control unit, an underwater cleaning unit and a connecting cable. The on-board monitoring and control unit is capable of displaying operating states and acquired images of the underwater cleaning unit and controlling the underwater cleaning unit. The underwater cleaning unit is capable of cleaning marine organisms and dirt attaching to the bottom of a large vessel and acquiring bottom images. The connecting cable is used to power the underwater cleaning unit and also to communicate the on-board monitoring and control unit with the underwater cleaning unit.

Description

technical field [0001] The invention relates to underwater cleaning equipment for large ship bottoms, belonging to the technical field of navigation equipment. Background technique [0002] The harm that the bottom of the ship produces fouling (marine accretion) is great. Organisms in seawater, such as barnacles, oysters, limeworms, bryozoans, and algae, etc., attached to the ship will slow down the speed of the ship, and marine organisms attached to the bottom of the ship will easily produce batteries with poor oxygen concentration and cause pitting. At the same time, in addition to promoting corrosion, the excrement of marine organisms will also invade the coating film of the bottom of the ship as it accumulates, and accelerate the corrosion of the hull below the waterline, thereby destroying the coating film and causing serious consequences. [0003] According to statistics, every 10um increase in the average roughness of a ship's hull due to fouling will lead to an incr...
