Ship hull descaling and flaw detection system

Abstract

The invention provides a warship hull descaling and flow detecting system which comprises a power supply system, a control system, a charging system, an energy storing system, a plasma shock wave generating mechanism, a flaw detection monitoring system, a surface flushing mechanism and an adsorbing and walking robot. When the system runs, probes of the plasma shock wave generating mechanism, the surface flushing mechanism, the adsorbing and walking robot and the flaw detection monitoring system are in underwater operation. Organisms attached to the surface of a warship hull are subjected to primary cleaning by the aid of strong sound shock waves generated from discharging of underwater plasmas, the organisms attached to the surface of the warship hull fall off or are loosened, and then the loosened attachments are cleaned by the aid of the surface flushing mechanism. The descaling effect can be detected through the flaw detecting system after descaling operation, and non-destructive detection can be performed on the surface of the warship hull.

Description

technical field [0001] The invention relates to marine engineering equipment, in particular to an automatic system for descaling and flaw detection of ship shells by using underwater plasma strong sound pulses. Background technique [0002] A large number of marine organisms are often attached to the waterline of the ship. After the marine organisms attach, the bottom of the ship will be rough and heavy, increasing frictional resistance, reducing speed, and increasing fuel consumption; blocking seawater pipes and submarine valves; generating noise that hinders sonar work, reducing Sonar properties; promotes corrosion, allowing wooden boats to be bored by shipworms or psyllids. If this kind of organisms are fixed on the ship, as time goes by, the number of reproduction will increase, and the area will continue to increase, and even cover the entire underwater part of the ship. Such fouling organisms will increase the weight and navigation of the ship. The resistance of the s...

Problems solved by technology

[0005] The device invented by the patent "Marine Attachment Removal Device" (Patent No. 01278370.6) is a floating frame that can remove organisms attached to offshore facilities at any time, but its structure is complex and its reliability is low, and the acid sprayed by the acid spray pipe The liquid may also have a corrosive effect on facilities and ships, which is not environmentally friendly

The patent "Electrochemical Method for Removing Biological Pollution from Marine Ships" (Patent No. 200610016914.2) proposes a method that uses the hull as the cathode and metal titanium or graphite as the anode, and uses the pulse current generated between the two poles by a pulse power supply to treat marine organisms. The disadvantage of the cleaning method is that only part of the hull can be cleaned each time, the maneuverability is poor, and the current intensity is small, so the cleaning effect is not thorough enough

Moreover, none of the above-mentioned patents has the flaw detection function for the hull of a ship.
