横波の場合には船体が転覆する等の虞れがあった。The bottom surface of a conventional ship is
Normally, it is set in a flat state with some curvature. For this reason, when a longitudinal wave or a transverse wave is received, the navigation of the hull is not allowed to be unstable, and in the case of an extreme longitudinal wave or a transverse wave, the hull may be capsized.

事を特徴としている。In order to achieve this object, the ship of the present invention has the following structure. The ship is composed of a ship body and capsizing means arranged in a protruding shape on the bottom surface of the ship body. The capsizing means are arranged on both port sides in the longitudinal direction, and the front end surface and the rear end surface are open and constant. It is characterized by being a cylinder through which a certain amount of water can pass.

常の深さと変化はない。In a ship having such a structure, cylindrical bodies protruding downward from the bow to the stern are attached to the starboard side and the port side of the ship bottom, respectively. A front end face and a rear end face of each of the pair of cylinders are open. Therefore, when the ship navigates, the water in the cylinder is full. The water in the cylinder passes in the direction opposite to the traveling direction of the vessel, and the draft for safe navigation (the depth in the water of the vessel) does not change from the normal depth.

く横ゆれする虞れはない。When a longitudinal wave hits a ship, the bow and stern of the ship originally move up and down largely, but the full water in the cylinder is caused by the outer peripheral water pressure at the front and rear end opening surfaces of the cylinder. Since it is not discharged suddenly, the weight of the water filled in the cylinder stabilizes the ship, and it does not move up and down significantly. In addition, when a transverse wave hits a ship, the ship is supposed to roll in both directions, but since there are cylinders on both sides, in order to lift one cylinder, the As a result of requiring more force than the weight of water, there is no risk of the vessel swaying significantly.

には適所に補強リブ１２が設けてある。The ship comprises a ship body 2 and a capsizing prevention means 1 provided on the bottom surface 21 of the ship body 2 in a protruding manner. The ship main body 2 has a structure similar to that of a known ship, and a small carrier ship is shown in the embodiment. The feature of the present invention resides in that the rollover preventing means 1 is provided. The overturning prevention means 1 is cylindrical bodies 11 provided on both sides of the bottom surface 21 of the ship body 2. This cylinder 11 is
Each of them is arranged linearly in the longitudinal direction from the bow 2a of the ship body 2 to the stern 2b side. In the embodiment, the length of the cylinder 11 is set to about 6 m. Further, the cross-sectional area of the cylindrical body 11 is set to about 50 cm 2 . Further, both end surfaces of this tubular body 11 are open, and the bow-side open end surface 11
a is an inclined surface that descends and inclines toward the stern 2b side, and the stern-side opening end surface 11b is set to an inclined surface that descends and inclines toward the bow 2a side. Further, as shown in FIG. 2, reinforcing ribs 12 are provided at appropriate places inside the cylindrical body 11.

Cylinders 11 and 11 projecting downward from b are attached. A front end face and a rear end face of each of the pair of cylindrical bodies 11, 11 are open. Therefore, when a ship navigates
Water A in water is filled in the cylinders 11, 11. And
The filled water B in the tubular body 11 flows in the direction opposite to the traveling direction of the ship, and the draft for safe navigation (the depth in the water of the hull) does not change from the normal depth. Further, since the filled water B in the tubular body 11 flows in the direction opposite to the traveling direction of the ship, the traveling resistance is extremely small.

る。When a longitudinal wave hits the ship, the ship body 2
Originally, the bow 2a and the stern 2b would largely move up and down, but the filling water B in the tubular body 11 suddenly changes due to the outer peripheral water A pressure of the front and rear end opening surfaces 11a and 11b of the tubular body 11. Since the water is not discharged, the ship is stabilized by the weight of the filled water B in the tubular body 11 and does not move up and down largely. That is, in the embodiment, since the length of the tubular body 11 is 6 m and the cross-sectional area is 50 cm 2 , the weight of the tubular body 11 that stores the filled water B is 1.5.
The total weight of the pair of cylindrical bodies 11, 11 is 3 tons. Therefore, the amount of this becomes resistance to the lifting of the ship body 2, and the ship navigation against longitudinal waves can be stabilized.

Since the cylinders 11, 11 are provided on both port sides, in order to lift one cylinder 11, a force equivalent to the weight of the filled water B (force of 1.5 tons or more) is required. result,
There is no risk of the ship swaying significantly, and it is possible to stabilize the navigation of the ship against shear waves.
