The working principle of the invention is as follows:

when the autonomous underwater robot needs to be autonomously recovered, the underwater robot sails to a water area where a recovery platform (such as an unmanned ship) is located through communication guide equipment; when the underwater robot reaches a designated water area, the capturing mechanism at the front end is opened, at the moment, the recovery device of the invention is started, and the slideway mechanism 4, the lead screw sliding table mechanism B2 and the clamping mechanism 3 work cooperatively.

First, the motor B13 in the screw sliding table mechanism B2 drives the screw B8 to rotate, and the sliding table a5, the sliding table B6 and the clamping mechanism 3 move together toward the rear end of the fixed frame 1. When the clamping mechanism 3 reaches the extreme edge of the tail end of the fixed frame 1, the motor B13 stops working; the underwater robot further approaches to the recovery device from the water surface, enters the interior of the clamping mechanism 3 under the guidance of the guide plate 17, contacts the head end limit plate 10, and is triggered by the position switch A9; at the moment, the screw sliding table mechanism A14 starts to move under the control of the control system, and the motor A drives the clamping frames 15 on two sides to clamp the underwater robot through the screw A, the sliding table C26 and the sliding table D27. After the underwater robot is clamped by the clamping frame 15, the position switches C20 on the clamping blocks 28 on the front side and the rear side of the clamping frame 15 are triggered, and the motor A in the screw rod sliding table mechanism A14 stops working; the control system controls a motor B13 in the lead screw sliding table mechanism B2 to start working, and the clamping mechanism 3 drives the underwater robot to move towards the inside of the fixed frame 1 on the roller 21 under the action of the lead screw sliding table mechanism B2. During the movement, the guide plate 17 rotates along the rotating shaft of the hinge 19 under the action of the hinge 19 and the fixed frame 1. When the underwater robot finishes recycling, the position switch B11 on the tail end limit plate 12 is triggered by the head end limit plate 10, the motor B13 in the screw rod sliding table mechanism B2 stops working, and the underwater robot finishes recycling.
