Settlement cups are sleeved on the central tube, and two adjacent settlement cups are inserted together. A multi-rib separating bowl is embedded in the settlement cup. The settlement cup is crown shape. The bottom of the settlement cup is formed with multiple ribs. An angle is formed between the convex rib of the bottom of the settlement cup and the horizontal line. The top edge of the settlement cup is sawtooth shape corresponding to the shape of the cup bottom. An annular space is formed between the cup base of the settlement cup and the central tube. The central tube corresponding to the annular space is provided with a fluid inlet. The shape of the multi-rib separating bowl is identical to that of the bottom of settlement cup, and the multi-rib separating bowl is provided with a fluid passage. The downhole device solves the effective separation of oil and water.
