Lateral pushing device

The invention provides a side pushing device. The side pushing device comprises a barrel and a side pushing device body. The cylinder body is transversely connected to a ship body, and the cylinder body is provided with a cylinder body internal cavity; the cylinder body comprises an inner cylinder body and an outer cylinder body; the outer cylinder body sleeves the inner cylinder body to form a double-layer structure, and the two ends of the outer cylinder body are plugged through plugging structures, so that a closed interlayer cavity is formed between the inner cylinder body and the outer cylinder body, and the interlayer cavity is filled with a sound insulation medium; the lateral thruster is arranged in the inner cavity of the column body, and the flow direction of fluid generated by a propeller of the lateral thruster is the same as the axial direction of the inner cavity of the column body. By arranging the barrel with the interlayer cavity, vibration is reduced, and the technical problem that in the pr
