Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ship, in particular, by lowering the center of gravity of the hull to suppress swaying due to waves and stabilizing it, and by flattening the bottom of the ship, it is difficult for grounding to occur, and even if the grounding occurs, damage to the hull may occur. It also relates to a ship with a hull structure that keeps against minimal flooding.

[0002]

[Prior art and its problems]

 In general, the hull of a ship has a convex shape whose bottom end, which is parallel to the longitudinal direction along the traveling direction, cuts waves, and is formed into a curved surface along both side faces of the hull from this bottom end. Because of this, it was excellent in the action of cutting waves in the course direction, but this bottom shape did not make it economically navigable.

[0003] Furthermore, a ship having a ship bottom of such a shape is apt to be aground in a shallow seabed or a coral reef sea, so that it has been impossible to navigate when it is very difficult to navigate.

Further, in the case of a ship having a ship bottom having the above-described shape, when it is housed in a dock and fixed, it cannot be sufficiently stabilized unless it is a fixing base that matches the shape of the ship bottom.

[0005]

[The purpose of the device]

 The present invention has been made in view of the above-mentioned problems of the prior art, in which the bottom of the ship is formed in a flat shape to reduce the resistance of waves when navigating and it is possible to navigate with a small amount of power. The enclosure surrounding the room is made of a waterproof material to prevent water intrusion even if the hull is damaged, and the center of gravity of the hull is low, making it difficult to capsize.Furthermore, the ship is docked and fixed. Even if it is carried out, it is an object of the present invention to provide a ship that can be sufficiently stabilized if the surface that hits the bottom is a flat surface even if it is not a fixed base of a fixed shape because it is a straight bottom.

[0006]

[Key points of the device]

 According to the present invention, according to the present invention, in the hull of a ship, the bottom end surface which is the outer bottom of the ship and the back surface of the bow are formed in a flat shape, and the bow is sharply angled from the back surface of the bow toward the tip of the bow. The inner side surface along the vicinity of the waterline of the ship is partitioned by a plate-like material to form a partition part, and the partition part is filled with a housing formed of a waterproof material, and the partition is defined as described above. This is accomplished by providing a hull structure for a vessel configured to keep the compartments sealed.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic side view showing a hull structure of a ship according to the present invention.

In the figure, the hull structure 1 of a ship is formed with partition sections 4 that are partitioned into appropriate dimensions along the vicinity of the water line from the bow 2 side to the stern 3 side as shown by the broken lines in a rectangular line. It is being touched. The partition 4 is made of a material that forms the hull structure and is formed integrally with the hull, or is formed by fixing a plate material along the side surface inside the hull with an adhesive or the like. Is packed so that the inside surrounded by the plate material is filled with a case made of glass fiber which is a waterproof material. Then, by sealing the compartment 4 in which the housing is packed with a lid (not shown), for example, when the ship is damaged or damaged from the outside to the inside of the side surface of the hull due to external force such as collision or stranding. In such a case, only the occurrence of water in the compartment 4 at the damaged portion does not cause any damage to the entire hull, and the degree of water infiltration is due to the case being filled in the compartment 4. The volume of the body does not submerge.

FIG. 2 is a schematic plan view showing the hull structure of the ship of the present invention. In the same figure, the hull structure 1 of a ship is provided with the above-mentioned partition sections 4 along both side walls 5 of the hull from the bow 2 toward the stern 3 as in the above. In particular, the area around the stern 3 is spread over the entire floor area. Then, as described above, the partition sections 4 are formed so as to be lined up near the waterline of the hull. The situation near the bottom of the ship is shown in Figs. 3 (a) and 3 (b). From the center of the hull to the bow 2, it is formed on the side of the hull at an intermediate position between the bottom and the deck as shown in Fig. 3 (a). The stern 3 of the hull has partition sections 4 formed on both sides of the hull and in the center of the hull as shown in FIG.

FIG. 4 is a schematic rear view showing the hull structure of the ship of the present invention. In the figure, the bottom 6 of the hull structure 1 of the ship has a flat bottom at its bottom end, and lateral sides are formed horizontally from both sides of the hull toward the center, and further downward from the end of the horizontally formed side. The ship bottom 6 is formed to be convex. The ship bottom 6 is formed in a flat shape, and the contour shape of a cross section taken in a direction perpendicular to the bow 2 toward the stern 3 appears linearly.

The ship bottom 6 is formed to be long in the traveling direction from the bow 2 to the stern 3 with respect to the entire hull. A bottom 6 is continuously formed from the bow 2, but the bottom 6 is cut off near the stern 3 on the way to the stern 3. Next, regarding the side surface shape of the bottom 6 of the ship, the hull is formed at a predetermined distance from the side surface 5 of the hull in a direction substantially perpendicular to the lower surface of the hull. The vertical distance of the ship bottom 6 is formed to have a predetermined length as shown in FIG. At a portion of the bottom 6 that ends near the stern 3, a shaft 7 protrudes from the inside of the ship to the outside of the ship, and a screw 8 is attached thereto. The screw 8 is attached to the stern 3 along the central axis (rotational axis) of the screw 8. 9 are configured.

FIG. 5 is a perspective view of the hull structure 1 of the ship having the above-mentioned structure. The upper half of the hull is no different from the conventional hull, but the shape of the bottom 6 is linear. It looks like a ski or a sled. The cruising condition of this ship at an increased speed is to make the bow 2 slightly face up and push the bottom 6 side of the stern 3 into the sea to sail on the waves. For this reason, since the weight of the hull is supported by the lift force of the bottom surface 6 in the sailing state, the propulsive force is small and it is economical.

Further, for example, when navigating in a shallow water or navigating a sea with coral reefs, the bottom 6 is flat, so that the risk of riding on the seabed or agrounding is avoided. Further, with this hull structure, even when it is housed and fixed in the dock, it is not necessary to use a fixed base having a curved surface, and therefore it can be easily fixed.

Further, since the engine room is provided inside the ship bottom 6 formed from the hull in a direction substantially perpendicular to the lower surface of the hull at a predetermined distance from the side surface of the hull, the hull is provided. It has a low center of gravity, has very little effect on transverse waves, and has excellent stability.

[0015]

[Effect of the device]

 As described in detail above, according to the present invention, the resistance at the time of navigation is small, so it is economical and excellent in stability because of its low center of gravity. It is extremely small and can be easily housed and fixed in the dock, and even if the hull is damaged due to a grounding or the like that occurred during navigation, the interior of the hull is finely divided to prevent flooding over the entire hull and avoid danger. It has become possible to provide a hull structure for a ship that is capable of operating.
