Abstract

The invention discloses an antifouling system for a ship propeller, which comprises a shore-based mobile seawater electrolysis chlorine making device, an underwater automatic positioning device, and an on-line residual chlorine monitoring unit for measuring and monitoring the concentration of residual chlorine around a propeller blade. The invention also discloses an antifouling method for the ship propeller, which comprises the following steps of: introducing seawater to the shore-based mobile seawater electrolysis chlorine making device; positioning the underwater automatic positioning device to the periphery of the propeller blade; measuring and monitoring the concentration of the residual chlorine around the propeller blade by using the on-line residual chlorine monitoring unit; feeding the measured and monitored signals back to the shore-based mobile seawater electrolysis chlorine making device; and injecting a proper amount of sodium hypochlorite solution to the periphery of the propeller blade according to the feedback information. The system has small volume and can move freely; the method has low operating cost, and is safe and effective; and the system and the method are particularly applicable to ships with low voyage rate.

Description

technical field [0001] The invention relates to an antifouling of ship propellers, in particular to a system and method for antifouling of ship propellers. Background technique [0002] At present, a variety of methods to prevent marine biofouling have been researched and developed at home and abroad, and the most commonly used and most common method is the antifouling coating method. Other methods include ultrasonic method, radiochemical method and physical method. In addition, some people have used antifouling methods such as low frequency acoustic method, protease antifouling method and copper-based coating by adding tetracycline. However, the antifouling effect of these methods is not very satisfactory, so it is difficult to promote the use. [0003] Antifouling paint is currently the most popular and applicable antifouling method. Ship antifouling coatings are mainly divided into two categories: metallic coatings and non-metallic coatings, and some of them are used to...
