Device for automatically attaching and detaching a towed sonar transmitter to and from an active-sonar tow line

摘要

The present invention relates to the handling, the attaching to a drag line and the putting to sea of a submersible craft, dragged by a surface vessel. The invention includes a system for automatically attaching and handling submersible craft towed by a tow line, comprising an automatic attaching device for carrying out the mechanical attaching of the submersible craft to the drag line and the linking of the submersible craft to the structure conveying the signals and the energy in this same line. The system according to the invention also includes an automatic device for handling the submersible craft, on which device the submersible craft is positioned when it is not attached to the drag line and from which it is separated after attachment, and which makes it possible to automatically position the submersible craft with respect to the drag line in such a way that the attaching and detaching can likewise be done automatically. The invention applies to towed active sonars in which the transmission antenna is integrated into a submersible craft and the reception antenna includes a linear antenna (streamer) towed behind the submersible craft.
