Example 6:
the invention relates to a three gorges filling-in-the-air ship type, which is matched with the existing standard ship type of 110m multiplied by 15.2m, fills up the waste of the existing standard ship type of 110m multiplied by 17.2m to the lock chamber passing rate of the three gorges, has obvious potential for improving the navigation capacity of the three gorges, and has the most obvious potential effect of filling cargo of about 5000t under the condition of 4.3m of draft of the ship type of the embodiment, and can reach ten thousand tons when two 5000t of filling of one lock, and related departments are recommended to guide to release the main pipe.
The disadvantage of this embodiment is that the width of the ship is small and the ship stability is not suitable for loading the cargo with high center of gravity such as container and the cargo with large stowage factor, but only suitable for loading the cargo with small stowage factor such as sand, stone, iron ore steel and the like. In this respect, in the present embodiment, the inflatable rubber back-up ball 1 is additionally disposed on the port and starboard sides, and the inflatable rubber back-up ball 1 is inflated sufficiently to have a corresponding buoyancy during self-propulsion, and is mounted at a position suitable for a distance of about 150m from the lowest edge of the back-up ball to the full-load water surface, and the ship's topsides are most suitably formed to have a height corresponding to the diameter of the flat shape 2/3 of the "back-up ball". The height of the ship can prevent the ship from forming water surface resistance in navigation, but the ship has additional buoyancy and has anti-tilting effect when being tilted under the action of external force. Also, on the way of navigation, the inflatable rubber leaning ball 1 is lifted to a proper height from the water surface by adopting a lifting device, and the suspension arm 2 of the inflatable rubber leaning ball 1 is fixed by adopting a positioning pin.
