TOOL FOR UNDERWATER HYDRODYNAMIC CLEANING OF SURFACES

FIELD: protection of underwater surfaces of ship's hulls and water-development works against biological fouling designing of cleaning tools. SUBSTANCE: tool has floating body made in form of disk with working nozzle for forming the jet of water and device for compensation of its reaction mounted on this disk. Working nozzle and compensation device are connected with water pump by means of common hydraulic passage and hose. Header consisting of two parts is mounted in lower portion of housing along its axis. Fixed part is located on lower plane of disk and is secured on it; rotatable part of header is located under this plane and holds the working nozzle. Device for compensation of water jet reaction is made in form of second working nozzle also mounted on this part of header. Reaction rotor is formed together with rotatable part of header and first working nozzle through skew-symmetric mounted on both nozzles relative to axis of holder. Fixed part of header is connected with common hydraulic passage. Axis of wheel undercarriage secured on lower plane of housing coincides with axis of rotation of rotor. Diameter of housing is equal to diameter of circle formed by intersection of axes of working nozzles with plane of support of undercarriage wheels during rotation of rotor. EFFECT: intensification of cleaning process and ease in use. 5 cl, 4 dwg
