power train for hydroacoustic transmitter as well as the use of the device for the transmission of hydroacoustic waves in a fluid

摘要

The invention refers to a driving device for hydroacoustic transmitters, including at least one actuating element (1), arranged to execute a reciprocating movement, wherein the movement of the actuating element (1) includes an increase and a decrease of the distance between two ends thereof, and at least one spring member (5, 27) which is connected to the actuating element (1) at said ends and which extends along a curved line between said ends, wherein the increase and the decrease of the distance between said ends result in a change of the curve of the spring member (5, 27) and thereby a movement of it. The device includes an element (12, 13, 28) for displacement of a mass, which displacement element (12, 13, 28) is connected to the spring member (5, 27) so that the movement of the latter is transmitted to the displacement element (12, 13, 28) and generates a displacement thereof, resulting in said mass displacement. Furthermore, the invention refers to the use of such a device for transmitting hydroacoustic waves in a liquid.
