METHOD AND DEVICE FOR CLEANING OF UNDERWATER SURFACES Russian patent published in 2013 - IPC B08B3/02 B63B59/08 

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning of underwater surfaces. Proposed method is implemented with the help of washing tool composed of carcass structure with washing appliances intended for spraying cleaning fluid. Said washing tool is shaped to bowl with built-in fluid feed nozzles arranged along bowl edges and central outlet atop said bowl to suck in fluid and contaminant. Note here that cleaning is performed as follows: structure is brought to surface to be cleaned so that bowl rim edge is located at a distance from said surface to set low dynamic fluid pressure at bowl outlet. To suck in water from ambient medium under said edge inside bowl and upward via outlet, fluid is sprayed via nozzles to cause bowl revolution and loosen contaminant at the surface. Note here that the mix of contaminant and water flows in settled water flow toward the center and upward to bowl inside top part to carry contaminant and water for further treatment.

EFFECT: efficient cleaning.
