Description

Underwater cleaning device and underwater cleaning system
Technical Field
The embodiment of the application relates to the technical field of underwater cleaning, in particular to an underwater cleaning device and an underwater cleaning system.
Background
Because a large number of shipping companies and shippers have no cargo source, the ships can only wait for voyage orders at the anchor. Because the ship is sailed or anchored in the marine environment with strong corrosiveness and strong adhesive force for a long time, normal maintenance is difficult to carry out, so that the parts below the waterline of the ship body are adhered with barnacles, oysters, bryozoans, huperzia serrata, lime worms, seaweed and other marine organisms, some rusts, rusty spots and the like which are difficult to remove. Thus, the smoothness of the hull surface is greatly affected, the resistance is obviously increased when the ship advances in water, the ship speed is reduced, the fuel consumption is obviously increased, and the carbon dioxide emission is increased. It is estimated that the fuel consumption of the hull increases with the increase of the surface roughness due to the attachment of marine organisms, and the performance of the ship decreases. In addition, the marine attachment consumes 40% more fuel as soon as the ship speed is reduced by 10%. In addition, marine attachments can influence the safe operation of ships and even cause accidents because of being attached to parts such as a propeller, a sonar, a propeller shaft and the like. Therefore, the removal of marine attachments plays an important role in the safe operation of ships and the reduction of energy consumption. The cost of cleaning marine attachments per year spent on the global marine vessels, offshore drilling platforms and other offshore facilities is statistically high in the hundreds of billions of dollars, and huge market demands exist.
Most of the existing technologies for cleaning underwater polluted garbage are manually cleaned by using a physical friction mode or high-pressure water mixed gravel, and cannot cope with complex cleaning working conditions and complex surface conditions, such as a 3D special-shaped curved surface structure, so that the cleaning efficiency is greatly reduced and even the cleaning effect cannot be achieved.
