Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hull structure for a submersible, and more particularly to a submersible with an integrated skin structure.

The hull structure of conventional submersibles is as shown in Figures 1 and 2. As shown in Figure 1, the hull structure consists of an outer skin 1 that matches the outer shape of the submersible and reinforcing members 2 attached to the inside of the outer skin 1. As shown in FIG. 2, the reinforced plastic outer shell structure member is configured to be attached to the outer surface of the metal frame structure member 3 with machine screws or the like.

Further, a buoyancy member 4 is attached to the frame structure member 3 with a band, a small screw, or the like.

However, in the hull structure of such a conventional submarine, it is necessary to create a box shape for each divided block in order to form the outer skin 1, and a large number of reinforcing materials 2 are separately manufactured and these are inserted inside the outer skin 1. There is a problem in that the number of steps required for installation is increased, leading to a significant increase in overall costs.

Furthermore, the frame structure material 3 where the outer skin 1 is attached
Materials such as titanium, which have high strength relative to their weight, are used for these, but there is a problem in that advanced processing techniques are required to shape the material to match the external shape of the hull.

In addition, since the outer skin 1 and the buoyancy member 4 are attached to the frame structure member 3 separately, the number of man-hours increases, and
Another problem is that there is a void immediately inside the outer skin 1 that is difficult to utilize effectively.

The present invention attempts to solve the above-mentioned problems in the hull structure of a submersible, and provides a submersible having an integrated skin structure that is easy to construct and allows for effective use of space inside the ship. The purpose is to

For this reason, a submersible equipped with the integrated skin structure of the present invention is a submersible that has a skin structure outside the frame structure, and the skin structure has a buoyant surface that corresponds to the external shape of the hull. and a reinforced plastic material laminated on the surface of the buoyancy material, and the frame structure member is formed into a polygonal shape by straight members, and is provided with a structure that covers the outer periphery of the frame structure member. It is characterized by being attached.

Below, a submersible equipped with an integrated skin structure as an embodiment of the present invention will be explained with reference to the drawings. Figure 3 is an explanatory diagram showing the manufacturing procedure of the skin structure, and Figure 4 is the skin of Figure 3. 1 is a partial perspective view showing a cross section of a submersible equipped with structural members; FIG.

As shown in FIG. 3, when manufacturing the integrated skin structural material S used for the submersible of the present invention, first, a surface 11a corresponding to the external shape of the hull is formed on the buoyancy material 11, such as a hard foamed resin. Then, cutting is performed while matching the planar mold 12, and the reinforced plastic material 13 is laminated on the surface 11a of the buoyancy material 11 thus obtained.

Such buoyancy material 11 and reinforced plastic material 1
In parallel with the process of manufacturing a large number of blocks of the outer skin structure material S integrally formed with 3, assembling work of the metal framework structure material 14 made of straight members is carried out as shown in FIG. A skin structure member S is attached to the outside of the frame structure member 14 as shown in FIG. As a means for attaching the skin structure material S to the frame structure material 14, appropriate means such as attachment pieces or adhesives are used.

In this way, according to the submersible equipped with the integrated skin structure S of the present invention, external forces due to waves and fluids can be withstood with sufficient strength due to the integrated structure of the reinforced plastic material 13 and the buoyancy material 11, and Layer of reinforced plastic material 13 as outer skin and frame structure material 1
4 can be effectively used as a buoyancy material space, which has the advantage of ensuring the required buoyancy.

In addition, the buoyancy material 11 can be easily molded using a flat mold 12 without the need for a box mold, and the processing can be easily corrected by cutting off the convex portions or filling the concave portions with resin, etc. There are also advantages to being able to do so.

The effects and advantages of the submersible equipped with the integral skin structure of the present invention are listed below.

(1) The outer shape of the reinforced plastic material 13 is determined simply by laminating it on the surface 11a of the molded buoyancy material 11.

(2) Since the layer of reinforced plastic material 13 as an outer skin and the buoyancy material 11 are integrated, there is no need to attach them separately to the frame structure material 14, and it is not necessary to attach them separately to the frame structure material 14, and it is not necessary to attach them to the frame structure material 14 separately. ) is no longer necessary, greatly simplifying the work and man-hours.

(3) It becomes possible to use all the frame structural members 14 as straight members, which contributes to simplifying the work and reducing the number of man-hours.

(4) Frame structural members, which were conventionally made up of curved members and could not be counted as effective strength members, can now be used as effective strength members by being made into truss structures made of straight members.

(5) The space between the outer skin and the frame structure material can be effectively used as a space for buoyancy material to balance the weight and buoyancy of the submersible, and by protecting the necessary buoyancy, the submersible can be made smaller. It is something.
