When the deck carrier is required to transport cargo, the hull 1 is first controlled to sail to the side of the cargo to be loaded, and then the hull 1 is gradually submerged and the distance between the main deck 3 and the water surface is gradually reduced by filling ballast water into the ballast water tank 5. When the main deck 3 is level with the cargo floor, the cargo is initially carried onto the main deck 3. During the handling of the cargo, the amount of ballast water in the ballast water tank 5 is constantly adjusted to ensure that the main deck 3 is always in a level state. When the goods move to the main deck 3, the limiting device is welded to the main deck 3 through the electric welding machine, and the limiting device abuts against the goods. After which part of the ballast water inside the ballast water tank 5 is discharged so that the hull 1 floats up and the distance between the main deck 3 and the water surface gradually increases.

As shown in fig. 4, the hull 1 is also internally provided with a platform deck 7, and the platform deck 7 is located directly below the main deck 3. The platform deck 7 is parallel to the main deck 3 and a dry bay 8 is formed between the platform deck 7 and the main deck 3. When the limiting device is welded on the main deck 3, the high-temperature welding gun cannot contact with fuel in the oil tank 4 and ignite the fuel in the oil tank 4, so that the oil tank 4 is not easy to explode, and the safety coefficient of the welding process of the limiting device is improved to a certain extent. The top surface of the platform deck 7 is provided with a plurality of rib plates 9 connected with the main deck 3, and the rib plates 9 are vertical to the platform deck 7. In this way, the rib plates 9 can provide supporting force for the main deck 3 when goods are placed on the main deck 3, so that the main deck 3 is not easy to deform due to compression.

As shown in fig. 1 and 2, the superstructure 2 is a surrounding building extending from one side of the hull 1 to the other side of the hull 1 above the main deck 3 of the hull 1. The various enclosure structures above the main deck 3 may be collectively referred to as superstructures 2 if not strictly distinguished. A concave cavity 10 is arranged on one side of the superstructure 2 close to the hull 1, and the concave cavity 10 transversely penetrates through the side wall of the superstructure 2, which faces the tail of the hull 1.

The length direction of the guide vane 11 is staggered with the length direction of the side pipe 62 and the end of the guide vane 11 away from the side pipe 62 extends towards the side away from the sealing end 612. When the ballast water tank 5 is filled with ballast water, air in the ballast water tank 5 enters the side pipes 62. When the air inside the side pipe 62 flows toward the main pipe 61 side and contacts the baffle 11, the flow direction of the air changes and faces the side facing away from the seal end 612. The air flowing from the side pipe 62 into the main pipe 61 is directed to the side away from the sealing end 612, so that the air inside the ventilation pipeline 6 flows smoothly and quickly. And after the guide vane 11 is disposed in the main pipe 61, the orifice of the main pipe 61 is reduced, so that the flow velocity of the air in the main pipe 61 is increased when the air flows through the guide vane 11, and the air in the main pipe 61 is smoother and faster.

The driving member 134 is disposed on the outer ring 131 and is used for driving the outer ring 131 to rotate around its own axis.

The driving member 134 includes a connection post 1341, a connection rod 1342, and a fan blade 1343. The cross-sectional shape of the connection post 1341 is circular, the connection post 1341 is located inside the outer ring 131, and the axis of the connection post 1341 coincides with the axis of the outer ring 131. The connecting rod 1342 has one end connected to the inner side wall of the outer ring 131 and the other end connected to the outer side wall of the connecting post 1341, and the connecting rod 1342 extends radially along the connecting post 1341. The number of the connecting rods 1342 is several and the connecting rods 1342 are distributed in a circumferential array with the axis of the connecting column 1341 as the center.

As shown in fig. 3, 5, and 6, when ballast water is filled into the ballast tank 5, air in the main pipe 61 flows toward the side facing away from the seal end 612. During the air flow, the air contacts the side wall of the fan blade 1343 facing the mouth end 612, so that the fan blade 1343 drives the connecting post 1341 and the outer ring 131 to rotate. At the same time, the connecting block 133 slides inside the sliding groove 12 and drives the outer ring 131 to move away from the sealing end 612. In the process of moving the outer ring 131, the bristles 132 on the outer side wall of the outer ring 131 and the inner pipe wall of the main pipe 61 move relatively, and the bristles 132 remove impurities attached to the inner pipe wall of the main pipe 61.

The connecting post 1341 has a cavity 14 disposed therein and the cavity 14 is opposite the fan blade 1343. The end of the fan blade 1343 close to the connecting post 1341 is fixedly connected with a cylindrical connecting rod 15, the connecting rod 15 extends along the radial direction of the connecting post 1341, and the end of the connecting rod 15 far away from the fan blade 1343 protrudes out of the inner side wall of the cavity 14.

When the fan blades 1343 rotate a certain angle, and the air flowing inside the main pipe 61 can drive the outer ring 131 to rotate reversely, the outer ring 131 moves toward the sealing end 612. When the first travel switch 19 is separated from the inner sidewall of the slide groove 12 facing away from the closing end 612, the servo motor 17 stops operating. When the outer ring 131 moves to the position where the second travel switch 20 abuts against the inner groove wall of the sliding groove 12 toward the seal end 612, the second travel switch 20 sends an electric signal to the servo motor 17, so that the servo motor 17 rotates reversely. When the servo motor 17 rotates in the reverse direction, the drive bevel gear 18 provided on the output shaft of the servo motor 17 rotates in the circumferential direction, and the rotational angular velocity of the drive bevel gear 18 is the same as the rotational angular velocity of the output shaft of the servo motor 17.
