The invention relates to the techniques of hydrodynamic cleaning of underwater surfaces of various facilities. The invention makes it possible to improve the service performance of a nonreactive hydrodynamic surface cleaning tool. The inventive tool is comprised of a body with handle (1) containing channels (2) for feeding a working fluid. The barrel (3) is connected to the body with handle (1) and to a working jet (4). A protective bar (5) and a connector (6) are mounted on the body with handle (1). Said channels (2) communicate with a high-pressure source through said connector (6). The body with the handle (1) is provided with a working fluid flow regulator (8) which comprises a lever (9). The free end of the barrel (3) comprises a mouthpiece (10). The nozzle (4) is mounted on said mouthpiece (10). A high pressure chamber is mounted behind the face of the barrel (3). A nozzle mounted on the mouthpiece (10) comprises control openings. An ejector is formed by crossing channels made around the face of the barrel (3). The nozzle comprises an ejector regulator having the shape of a control ring, which includes openings interacting with the control openings of the nozzle. A support bracket is mounted on the ejector regulator. The axis (20) of the barrel (3) can follow a straight line or a curve.

L'invention relève des techniques de nettoyage hydrodynamique des surfaces sous-marines de différentes installations. L'invention permet d'améliorer la performance d'usage d'un outil hydrodynamique non réactif destiné au nettoyage de surfaces. L'outil de l'invention comporte un corps à poignée (1) comportant des canaux d'amenée de fluide actif (2). Le canon (3) est relié avec le corps à poignée (1) et la buse de travail (4). Une barre de protection (5) et un raccord (6) sont montés sur le corps à poignée (1). A travers le raccord (6), les canaux (2) communiquent avec une source haute pression. Le corps à poignée (1) est muni d'un régulateur (8) de débit du fluide actif comportant une manette (9). L'extrémité libre du canon (3) comporte un embout (10). La buse (4) est montée sur l'embout (10). Une chambre haute pression est installée derrière la tranche du canon (3). Un ajutage monté sur l'embout (10) comporte des orifices de réglage. Un éjecteur est formé par des canaux traversants faits autour de la tranche du canon (3). L'ajutage comporte un régulateur de l'éjecteur se présentant comme un anneau de réglage qui comprend des orifices interagissant avec les orifices de réglage de l'ajutage. Une ferrure de support est montée sur le régulateur de l'éjecteur. L'axe (20) du canon (3) peut suivre une ligne droite ou une courbe.
