The invention provides a sampling device for a sampling ship to collect the ocean micro-surface layer. The sampling device comprises a cylindrical shell, the shell comprises a side wall and a bottom wall, a funnel-shaped collector is arranged in the shell, a small hole is formed in the bottom of the collector along the central axis of the collector, the large-caliber edge of the collector is the same as the inner diameter of the shell, and the collector is fixed in the side wall of the shell; the collector divides the interior of the shell into a sampling bin and a collecting bin; the sampling bin is located at the upper part of the collecting bin, a plurality of partition plates with the same size are accommodated in the sampling bin, the sampling bin is divided into a plurality of fan-shaped subareas by the partition plates, the partition plates can be removed from the top of the sampling bin, and the partition plates can rotate relative to the sampling bin when being placed in the sampling bin; the top end
