Abstract
PURPOSE: To make it possible to open and close doors without using a drive means by making a floating-body doors hinged to the ship's slides open and close by their own weight and the buoyancy exerted thereon.
CONSTITUTION: When the ship is unloaded, only the lower end of floating-body door 18 is slightly dipped into the water. Since the buoyant force exerted on floating-body door 18 is smaller than its own weight W, floating-body door 18 is closed on the ship's body by its own weight W. When the ship is loaded with earth and sand to the full, almost all of floating-body door 18 submerges in the water; hence, the buoyant force exerted on floating-body door 18 becomes larger than its own weight W. Consequently, moment of the buoyant force F.l1, which tends to open floating-body door 18 becomes much greater than moment of the door's weight W, and further, the moment due to the pressure of earth and sand which tends to open the door operates. Hence, when sealing device 36 is unlocked, floating-body door 18 opens instantly.
