An underwater automatic clean device for propeller and a cleaning method thereof

Abstract

An underwater automatic clean device for a propeller and a cleaning method thereof, includes a high-pressure water supply device positioned on the shore, The high-pressure water supply device is connected with the underwater robot through a communication cable of the underwater robot and a high-pressure water pipe, the output end of the underwater robot is provided with an underwater manipulator,the underwater manipulator is provided with a cavitation cleaning device through a connecting device, and the output port of the cavitation cleaning device is butted with the blade of the propeller. The underwater robot is equipped with an underwater robot hand, and the cavitation cleaning device is clamped by a connecting device, and the high-pressure water supplied by the high-pressure water supply device is injected to clean the propeller according to the cavitation principle. The three positioning rods of the underwater vehicle are positioned relative to the propeller by the lateral thrustforce generated by the self-propeller, An underwater manipulator clam that cavitation cleaning device to complete the partial area clean of the propeller blade surface, an underwater robot moves according to a preset path to clean the entire propeller blade surface, and rotate the propeller to complete all the blade surface cleaning of the propeller. The underwater vehicle clamps the cavitation cleaning device to complete the local area cleaning of the propeller blade surfaces.

Description

Technical field [0001] The invention relates to the technical field of mechanical automation devices, in particular to a propeller underwater automatic cleaning equipment and a cleaning method thereof. Background technique [0002] Propellers play an extremely important role in the navigation of ships. Long-term immersion of ships in seawater will adhere to marine organisms, reduce the mechanical efficiency of the ship's propulsion system, and increase fuel consumption. The marine organisms attached to the propeller reduce the effective power of the propeller by 20%. Regular cleaning of the hull and the surface of the propeller is of great significance for keeping the ship sailing efficiently. [0003] The propeller structure has the characteristics of complex spatial location, not easy to be automatically cleaned, and its material is relatively soft, which brings great difficulties to the cleaning work. [0004] At present, in the prior art, underwater cleaning methods mainly inclu...
