Ship propeller underwater cleaning device and cleaning method thereof

Abstract

The invention provides a ship propeller underwater cleaning device. A clamping and positioning jaw mechanism is mounted on the bottom surface of a horizontal mounting plate, a cleaning module moving mechanism is mounted on the plate surface of a front mounting plate, and a control system hardware mechanism is mounted on the plate surface of a rear mounting plate; a horizontal propeller assembly ishorizontally arranged around the whole formed by the front mounting plate and the rear mounting plate, the front mounting plate and a control system hardware mechanism are connected with the horizontal propeller assembly, and a vertical propeller assembly is installed on the upper portion of the rear mounting plate; and a distance measuring sensor assembly is mounted on the upper surface of the horizontal mounting plate at the front part of the front mounting plate. The invention further provides a cleaning method of the cleaning device. Efficient propeller underwater cleaning operation is achieved, the clamping position of the cleaning device can be rapidly and automatically positioned, the optimal cleaning path is planned before cleaning, and therefore the cleaning efficiency and the automation and intelligence degree are further improved.

Description

Technical field [0001] The present invention relates to the field of ship propeller cleaning techniques, and more particularly to a ship propeller underwater cleaning device and a cleaning method thereof. Background technique [0002] As the core component of the ship as a ship, it has good hydromine performance and efficient advance efficiency, but because the ship's sailing propeller is attached to marine creatures such as a vinegy, seaweed, thereby increasing the ship's sailing fuel loss, and Shorten the operating life of the blade, causing huge economic losses, therefore requires regular cleaning of the propeller. [0003] At present, the propeller cleaning is mostly cleaning the water cleaning equipment with professional diver, but the artificial underwater operation is affected and constrained by the conditions such as water, ocean flow, marine life, and sub-conditions, resulting in traditional artificial cleaning operations that cannot be satisfied. Requirements for constr...

Problems solved by technology

[0004] None of the existing cleaning methods for marine propeller underwater cleaning devices can solve the problem well. For example, a propeller underwater cavitation cleaning device and its use method described in patent ZL201810920885.5 drive the front end by controlling the movement of the mechanical arm The installed cavitation cleaning disc cleans the surface of the blade, but the mechanical structure of the device lacks stable positioning during the cleaning process, and only relies on the interaction of the propeller to maintain the relative position in the water, which is greatly disturbed by ocean current fluctuations; and As described in the patent ZL201810921297.3, a three-point positioning propeller underwater cleaning device improves the positioning stability when cleaning the blade surface, but the cleaning area after each positioning is limited, and the cleaning process needs to be constantly changed. The position is positioned to ensure the complete cleaning of the blades, and the cleaning repetition rate is high; another example is an underwater hull cleaning robot described in patent ZL201510593564. The clamping part cannot be cleaned, and the clamping position needs to be changed several times to complete the overall cleaning, which greatly affects the cleaning efficiency of the propeller
