Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0033] In order to reduce the increased navigation energy consumption and cost caused by untimely cleaning of the ship, we have developed a high-voltage pulse discharge hull surface cleaning method and device carried by an underwater robot, which can be efficient, energy-saving, and automatically clean the surface of the hull without docking. Removed attachments. The equipment of the device is one-time investment, low operating cost, no environmental pollution, and has good application prospects at home and abroad.
[0034] Such as figure 1 , figure 2 As shown, a high-voltage pulse discharge hull surface cleaning device carried by an underwater robot includes an information acquisition unit...

Abstract
The invention discloses a device and a method for cleaning the surface of a high-voltage pulse discharge ship body carried by an underwater robot, and belongs to the field of machinery. The device ischaracterized in that an underwater high-voltage discharge technology is applied, a plasma effect, a cavitation cleaning effect, a shock wave effect and a hotspot effect during discharge are utilized,and timely and efficient automatic cleaning of ship body attachments is realized; and the device comprises a high-voltage pulse power supply, an information acquisition unit, a control unit, a foaming cleaning unit and an umbilical cord. The device and the method have the following beneficial effects that 1, the mode of high-voltage pulse discharge foaming can fully utilize the shock wave effectduring cavitation bubble generation as well as the cavitation jet effect and the shock wave effect during cavitation bubble collapse, and the device has no requirement for the cleaning medium; 2, thedevice is light and exquisite and can be used for carrying an underwater robot, and additional mechanical power is not needed; 3, docking is not needed for underwater cleaning of the surface of the ship body, and automatic cleaning can be achieved at sea; and 4, the middle steps of draining the water of the ship body are omitted, and the cleaning cost is reduced.
Description
technical field [0001] The invention relates to a method and a device for cleaning the hull surface of a high-voltage pulse discharge carried by an underwater robot, belonging to the field of machinery. Background technique [0002] The number of ships worldwide reaches hundreds of thousands, and China is the largest ship-owner country in the world, with 5,206 ships. Ships have been navigating in the environment of strong corrosive seawater and strong adhesion of marine organisms for a long time, and a variety of microorganisms that are difficult to remove adhere to the part below the waterline, which will increase navigation resistance, increase fuel consumption, and increase exhaust emissions. [0003] However, the existing hull cleaning technology has a series of disadvantages. The low efficiency of manual cleaning and the lack of docks make it impossible to clean the ship in time, which greatly increases the transportation cost. Contents of the invention [0004] Aimi...
