The storage tank 23 is used to temporarily store the sucked sea cucumber, after the storage tank 23 is filled, the end effector 02 is pulled back to the ship body 01 to collect the sea cucumber, so as to improve the working efficiency. The sea cucumber is caught by the suction device 24, which can effectively reduce the damage rate during the catching of the sea cucumber.
[0028] Optionally, the anti-backflow device is arranged in the guide pipe 22, and the anti-backflow device is used to prevent the sea cucumber sucked into the guide pipe 22 from falling back into the water due to gravity.

During fishing, the end effector 02 sometimes needs to move to the edge of the through hole 11 on the hull 01. The up and down movement of the pulley bracket 45 relative to the drive assembly bracket 44 can prevent collisions between the rope 03 and the hull 01.
