A marine fouling biological cleaning robot on the bottom of a ship

Abstract

The invention discloses a marine fouling biological cleaning robot at the bottom of a ship, which comprises a body, walking devices arranged on both sides of the body, an adsorption device arranged at the bottom of the body, a cleaning device, a control device and a driving device arranged on the body. The cleaning device is used to remove organisms attached to the surface of the hull, the walking device is used to drive the body to advance and turn, the adsorption device is used to adsorb the body on the surface of the hull, and the driving device is used to drive the walking device. The control device described above is used to control the robot’s movement, steering, and cleaning of the attached organisms on the hull. The entire cleaning process can be completed intermittently when the ship calls at the port, and does not need to be carried out in the dock, which shortens the cleaning cycle of the ship’s exterior and reduces the cost of cleaning Low cost, simple structure, wide source of raw materials, convenient operation and strong practicability.

Description

technical field [0001] The invention relates to the technical field of marine biological cleaning on the surface of ship hulls, in particular to a marine fouling biological cleaning robot at the bottom of a ship. Background technique [0002] After a long-term operation of the ship, a large number of marine organisms such as seaweed and shellfish are often attached to the bottom of the ship, which increases the quality of the ship. Most of the ship's decontamination work needs to be carried out in the dock, but the number of large docks in China is insufficient, the docking time is long, and the cost is expensive, which is easy to cause the loss of stoppage and increase the transportation cost. Greenhouse gases produced by fouling organisms that reduce the navigational performance of ships account for 9%-12% of the global fleet's greenhouse gas emissions. [0003] At present, the underwater cleaning and repairing hull technology has been approved by various parties such as ...

AI Technical Summary

Problems solved by technology

[0004] Existing methods for cleaning the bottom of a ship include high-pressure water gun scouring, chemical reagents, and cavitation water jet robots. Among them, the use of high-pressure water guns to wash the surface of the hull often requires manual diving under the ship. This method has the disadvantages of high labor intensity and low efficiency. ;Using chemical reagents to act on the bottom of the ship can achieve the effect of non-destructive shedding, but it will cause serious environmental pollution; although the cavitation water jet robot reduces labor intensity, high efficiency and no pollution, but due to the air bubbles in the cleaning process Uncontrollable, it will inevitably cause damage to the bottom protective layer and steel plate, thus aggravating the corrosion of the bottom of the ship
