Underwater acoustic beacon device capable of being ejected and suspended

The invention provides an underwater acoustic beacon device capable of being ejected and suspended. The device mainly comprises a beacon main body, an ejection assembly, a detection module and a release mechanism. The beacon body is installed along the axis in the shell of the ejection assembly, and the ejection assembly is fixed to underwater equipment. And the beacon main body is connected with the release mechanism through the T-shaped rotating shaft. And the detection module is mounted in the release mechanism. And after the detection module transmits a release command, the release mechanism executes the rotation of the T-shaped rotating shaft, and the beacon main body is popped out under the action of the pretightening force of the ejection assembly. The beacon main body can suspend in a water depth range in which underwater acoustic signals can be detected under the action of the connecting assembly and the floating body of the beacon main body. According to the invention, underwater equipment falling on a rugged seabed and a heavy metal surrounding area can be searched and positioned, the problems that an underwater acoustic beacon signal is covered and interfered and the like are effectively solved, and the searching and positioning efficiency of an underwater target is improved.
