Description

TECHNICAL FIELD

[0001] The utility model relates to a ship body cleaning equipment, especially to a ship body outer wall cleaning device. BACKGROUND

[0002] After a period of navigation, marine organisms will attach to the underwater part of the ship body, which will cause the navigation speed of the ship to slow down, the oil consumption to increase, and further increase the operation cost of the ship navigation.

[0003] Therefore, it is necessary to clean the attachments on the outer side of the ship bottom regularly. The traditional manual cleaning mode needs to move the ship to the dock, which has low cleaning efficiency, high risk coefficient and requirements for the use of the dock. Therefore, in recent years, an underwater ship body cleaning device that can directly clean the attachments on the outer side of the ship bottom has appeared in the market, such as the "underwater ship body cleaning robot" disclosed in Chinese patent CN110282092A. The cleaning robot includes a rack, a cleaning brush driven by a power mechanism is arranged on one side of the rack, a walking mechanism, a buoyancy structure and a propeller are further arranged on the rack, the propeller can generate an acting force to make the rack adhere to the bottom of the ship body, the propelling force of the propeller can be adjusted, and the attitude of the rack can also be adjusted. The rack walks along the ship body by using the walking mechanism, and the cleaning brush completes the cleaning of the outer side of the ship body in the walking process. The buoyancy structure is used to generate upward buoyancy to the rack to avoid sinking into the seabed.

[0004] The existing underwater ship body cleaning robot has the following problems: the buoyancy structure generally adopts a floating material design that is separated from the main body of the rack, such as a foam floating material or a floating bucket floating material, etc. Such buoyancy structure will occupy additional space of the machine body, and is easy to be damaged. When such floating material is used in seawater for a long time, due to the water absorption characteristics of the material, marine organisms will enter the gap between the material and produce a pungent smell.
