Description
креплен ролик 9. На вибраторе 2 укреплена пластина 10 с фигурным вырезом 11, а ролик 9 размещен в этом вырезе. Форма выреза 11 оТ1редел ётс расчетным путем в соответствии с требуемой последовательностью (законом) поворота вибратора 2 (см. фиг. 3). Полость 12 между мембраной 7 и поршнем 5 заполнена несжимаемой жидкостью, например маслом. При различной глубине h хода трала 13 и длине L вытравленных ваеров излучение вибратора 2 должно быть посто нно направлено на судно 14 (или буксируемый приемник , не показанный на чертеже). В соотESelrCtBHir с этим в зависимости от указанных параметров должен мен тьс и угол а. Происходит это следующим образом. С изменением глубины h измен етс .гидростатическое давление, действующее на мембрану 7, и соотЬетственно перемещение порщн 5 в цилиндре 4. Это вызывает поворот вибратора 2, причем форма выреза 11 обеспечивает поворот вибратора 2 на угол, соответствующий графику на фиг. 3. Предлагаемое изобретение позвол ет обеспечить устойчивую гидроакустическуюroller 9 is fastened. On the vibrator 2, plate 10 with a figured notch 11 is fixed, and roller 9 is placed in this notch. The shape of the notch 11 oT1 is determined by calculation in accordance with the required sequence (law) of the rotation of the vibrator 2 (see Fig. 3). The cavity 12 between the membrane 7 and the piston 5 is filled with an incompressible fluid, such as oil. At different depths h of the trawl 13 and the length L of etched wafers, the radiation of the vibrator 2 must be constantly directed to the vessel 14 (or the towed receiver, not shown in the drawing). According to ESelrCtBHir, the angle a should also vary depending on the parameters indicated. It happens as follows. With a change in depth h, the hydrostatic pressure acting on the membrane 7 changes and, accordingly, the displacement of the pressure 5 in the cylinder 4. This causes the rotation of the vibrator 2, and the shape of the cut 11 ensures the rotation of the vibrator 2 by the angle corresponding to the graph in FIG. 3. The present invention allows to provide a stable hydroacoustic
