Flexible dynamic capture system for underwater motion load

The invention discloses a flexible dynamic capture system for an underwater motion load. The flexible dynamic capture system comprises a shell, a front-end flexible guide device, at least one tail flexible hand clamping and fixing device and a bottom retracting and releasing device fixed in the shell, the front-end flexible guiding device comprises a plurality of flexible arms which are fixed to the first rigid base in a circumferential array mode, and the flexible arms can be bent towards the inner side and the outer side of the circumference when driven. Each tail flexible hand clamping and fixing device comprises a plurality of flexible paws, and the flexible paws are divided into two groups to be fixed on a second rigid base; when the flexible paws are driven, the two groups of flexible paws can be relatively bent and wound; the bottom retracting and releasing device achieves lifting of the front end flexible guiding device and the tail flexible hand clamping and fixing device.
