[0056] Referring to Figures 1-21 The embodiment provides a hydrophone array unfolding support which comprises a mounting seat and a plurality of supports which are circumferentially connected to the mounting seat; one end of each support is rotationally connected to the mounting seat, and the other end is a free end to which a hydrophone 10 is connected; when all the supports are unfolded, the free ends of the supports are away from the mounting seat, and all the hydrophones mounted on the supports form a hydrophone 10 array.

[0057] In the embodiment, the hydrophone 10 is directly fixedly connected to the free end of the support, in use, all the supports are directly unfolded, the free ends of the supports and the hydrophones 10 thereon are away from the mounting seat, a hydrophone 10 array is formed, and then the hydrophone 10 array can be laid out, so that the laying efficiency of the hydrophone 10 array is improved; in addition, all the supports can be accommodated, the occupied space is reduced, and transportation or storage is facilitated.

[0058] Embodiment one
