The utility model relates to the technical field of ocean environmental protection. The utility model relates to a layered sampling device, in particular to a shipborne micro-plastic layered samplingdevice. The device comprises a water pumping device and a sampler, the water pumping device is connected with the sampler through a connecting pipeline; a gate valve, a pressure gauge, a flow meter and a check valve are sequentially arranged on the connecting pipeline; the sampler comprises a plurality of sampling units; each sampling unit corresponds to one sampling water layer; wherein the sampling unit is provided with a water filtering unit, the water filtering unit is sequentially provided with an inner coarse filtering net, a fine filtering part and an outer coarse filtering piece from inside to outside, the outer coarse filtering piece comprises a first coarse filtering net and a second coarse filtering net, the fine filtering part is arranged between the inner coarse filtering netand the first coarse filtering net, and the second coarse filtering net is arranged at the outermost end. According to the utility model, direct extraction of a multi-water-layer micro-plastic samplecan be realized, the blank of a micro-plastic sampling technology is filled up, and the sampling precision is high.
