Claims (3)

1. Способ подводной гидродинамической очистки корпусов судов, при котором на очищаемую поверхность воздействуют струей воды под давлением, вытекающей из рабочего органа, обеспечивая условие возникновения кавитации в зоне' очистки, отличающийся тем, что условие возникновения кавитации в зоне очистки обеспечивают одновременным воздействием на очищаемую поверхность струи воды и акустического излучения, получаемого от акустического генератора, размещенного внутри рабочего органа и работающего на энергии динамического напора самой струи.1. A method of underwater hydrodynamic cleaning of ship hulls, in which a cleaned surface is exposed to a jet of water under pressure flowing from a working body, providing a condition for the occurrence of cavitation in the cleaning zone, characterized in that the condition for cavitation in the cleaning zone provides a simultaneous effect on the surface being cleaned jets of water and acoustic radiation received from an acoustic generator located inside the working body and working on energy of the dynamic pressure of the jet itself . 2. Способ по п. 1, отличающийся тем, что воздействие на очищаемую поверхность корпуса судна струей воды осуществляют под углом, не превышающим 45o, и таким образом, что дальняя граница зоны очистки по оси рабочего органа лежит на очищаемой поверхности.2. The method according to p. 1, characterized in that the impact on the cleaned surface of the hull with a water jet is carried out at an angle not exceeding 45 o , and so that the distant border of the cleaning zone along the axis of the working body lies on the surface being cleaned. 3. Насадка для подводной гидродинамической очистки корпусов судов, включающая проточный канал с профилем, образованным соосно расположенными и последовательно сопряженными друг с другом входным конфузором, цилиндрической частью и выходной частью, отличающееся тем, что цилиндрическая часть выполнена в виде цилиндрической резонансной камеры, имеющей диаметр, больший, чем диаметры выходного отверстия конфузора и входного отверстия выходной части, выходная часть выполнена в виде рупора, а торцевые стенки резонансной камеры образуют вместе с выходным отверстием конфузора и входным отверстием рупора соответственно входное и выходное сопла резонансной камеры, которая в свою очередь вместе с соплами образует акустический генератор, при этом разница диаметров выходного и входного сопел составляет не более 0,3 от длины резонансной камеры, диаметр выходного отверстия рупора составляет не менее 0,04 от длины волны основной частоты резонансной камеры, а конфузор выполнен с углом конусности 10-20o.3. A nozzle for underwater hydrodynamic cleaning of ship hulls, including a flow channel with a profile formed coaxially arranged and serially connected to each other by an inlet confuser, a cylindrical part and an output part, characterized in that the cylindrical part is made in the form of a cylindrical resonant chamber having a diameter larger than the diameters of the outlet of the confuser and the inlet of the outlet, the outlet is made in the form of a horn, and the end walls of the resonance chamber form e with the outlet of the confuser and the inlet of the horn, respectively, the inlet and outlet nozzles of the resonant chamber, which in turn together with the nozzles forms an acoustic generator, while the difference in the diameters of the outlet and inlet nozzles is not more than 0.3 of the length of the resonant chamber, the diameter of the outlet the horn is at least 0.04 of the wavelength of the fundamental frequency of the resonance chamber, and the confuser is made with a taper angle of 10-20 o .
