Underwater drone for mine detection

摘要

The drone includes a connection line (22), pref. an optical fibre, for steering and control arrangements and a guide platform. The underwater drone (10) includes a metal detector and an antenna (26) connected to an electronic appts. (16). The antenna is movable between a rest position and a detecting position by a driving appts. (58).The antenna has a holder (60) for holding it fixed in the detecting position. A folding mechanism (28) has tandem antenna elements. In the rest position, the folding mechanism and the antenna tandem are held against the drone in a space-saving manner. The antennae are spread out for detection.
