Description

Support structure for underwater vehicles

The present invention relates to a support structure for an underwater vehicle.

The hull of an underwater vehicle that navigates underwater has a tubular shape to withstand water pressure. Deck and various devices are placed inside the ship. Such an arrangement is supported by a support structure inside the ship.

For example, Patent Document 1 discloses a support structure that supports the deck inside the ship. This support structure supports the deck from below and includes vibration damping means and shock absorbing means arranged in series. The vibration damping means damps the vibration transmitted from the deck to the hull (referred to as a pressure hull in Patent Document 1), and the impact damping means reduces the force transmitted from the hull to the deck. ..

It is sectional drawing of the support part which provided the displacement absorption member and the shock absorption member on an object. FIG. 5 is a cross-sectional view of a support portion in which a displacement absorbing member is provided on an object and a shock absorbing member is provided on a hull.

FIG. 1 shows an underwater vehicle in which the support structure 1 according to the embodiment of the present invention is adopted. The underwater vehicle includes a tubular hull 2 extending in a direction orthogonal to the paper surface of FIG. 1, an object 3 arranged in the hull 2, and a support structure 1 for supporting the object 3 in the hull 2.

In the present embodiment, the object 3 is a heating element unit in which a cooling liquid is stored in a housing 30 and at least one heating element 35 is immersed in the cooling liquid. For example, the heating element 35 may be a battery or various devices. On the upper surface of the housing 30, a supply pipe 31 for supplying the cooling liquid into the housing 30 and a discharge pipe 32 for discharging the cooling liquid from the housing 30 are provided. However, the object 3 may be a battery or various devices themselves, or may be a deck.

The support structure 1 includes a plurality of support portions 11 to 13 provided so as to be distributed in the circumferential direction of the hull 2. In such a configuration, a large object 3 can be supported. However, the number of support portions included in the support structure 1 may be one depending on the size of the object 3.

More specifically, two first support portions 11 are provided below the object 3, and two second support portions 12 are provided diagonally below the object 3, and both sides of the object 3 are provided. Is provided with two third support portions 13.

As shown in FIGS. 2 and 3, each of the first to third support portions 11 to 13 is a target on the side of the displacement absorbing member 5 interposed between the hull 2 and the object 3 and the displacement absorbing member 5. It includes a plurality of (eight in the example) shock absorbing members 6 that are separated from the object 3.

In the present embodiment, the displacement absorbing member 5 is provided on the hull 2 via the support base 4, and the shock absorbing member 6 is provided on the support base 4. The shape of the support base 4 differs depending on the positions of the first to third support portions 11 to 13, but in FIG. 2, the shape of the support base 4 is simply drawn as a substantially rectangular shape. However, the displacement absorbing member 5 may be provided directly on the hull 2 without going through the support base 4. In this case, the shock absorbing member 6 is also provided on the hull 2.

In each of the first to third support portions 11 to 13, the displacement absorbing member 5 elastically deforms the displacement of the object 3 caused by the increase in water pressure and the contraction of the hull 2 and the displacement due to the own weight of the object 3. Absorb. In the present embodiment, the displacement absorbing member 5 has a substantially cylindrical shape in which the diameter on the object 3 side is slightly smaller than the diameter on the hull 2 side. The displacement absorbing member 5 includes a fixing plate 53 fixed to the support base 4 by a bolt or the like shown in the drawing, a fixing plate 51 fixed to the object 3 by a bolt or the like shown in the drawing, and these fixing

plates

51 and 53. The elastic body 52 sandwiched between them is included. For example, the elastic body 52 is made of rubber, but various elastic bodies such as springs can be applied.

The shock absorbing member 6 is arranged so as to surround the displacement absorbing member 5. In the present embodiment, each shock absorbing member 6 has a columnar shape smaller than that of the displacement absorbing member 5. Each shock absorbing member 6 absorbs a shock by plastic deformation when the shock absorbing member 6 collides with an object 3 such as when a strong shock is applied to the hull 2 from the outside. For example, each shock absorbing member 6 may be a honeycomb structure, a porous body, a tubular body, or the like, or may be a combination thereof. Further, the material of each shock absorbing member 6 may be any of metal, fiber reinforced plastic, and resin.

The shape and layout of the displacement absorbing member 5 and the shock absorbing member 6 can be changed as appropriate. For example, as shown in FIG. 4, the number of shock absorbing members 6 may be reduced and the diameter may be increased. Alternatively, as shown in FIG. 5, each shock absorbing member 6 may be formed into a rectangular parallelepiped shape, or as shown in FIG. 6, each shock absorbing member 6 may be formed into an L shape in a plan view. Alternatively, although not shown, each of the first to third support portions 11 to 13 may have a plurality of displacement absorbing members 5 arranged so as to surround one shock absorbing member 6.

Returning to FIG. 2, in each of the first to third support portions 11 to 13, the gap H between each shock absorbing member 6 and the object 3 in the direction orthogonal to the upper surface of the shock absorbing member 6 is the following equation 1. Is set to meet.
H ≧ A + Bcos θ + C ... (Equation 1)
A: Maximum contraction amount of the hull 2 due to water pressure B: Initial contraction amount of the displacement absorbing member 5 in the vertical direction due to the weight of the object 3 C: With the center 50 of the displacement absorbing member 5 due to the navigation of the underwater vehicle (see FIG. 2) Maximum displacement of the object 3 on the virtual line (71 to 73 in FIG. 1) connecting the center 20 of the hull 2 θ: The vertical line 70 (see FIG. 1) passing through the center 20 of the hull 2 and the virtual line. Displacement angle (θ1 to θ3 in FIG. 1)

The maximum contraction amount A of the hull 2 due to water pressure is not the diameter but the radius contraction amount. The center 50 of the displacement absorbing member 5 is an intersection of the center line in the width direction and the center line in the height direction of the displacement absorbing member 5.

By setting the gap H between the shock absorbing member 6 and the object 3 so as to satisfy the equation 1, no matter where the shock absorbing member 6 is arranged on the inner peripheral surface of the hull 2, the hull 2 is exposed from the outside. The object 3 can be protected when a strong impact is applied.

As described above, in the support structure 1 of the present embodiment, the displacement absorbing member 5 is interposed between the hull 2 and the object 3, while the shock absorbing member 6 that is plastically deformed is separated from the object 3. , The deformation of the hull 2 due to the vibration of the object 3 and the water pressure is absorbed by the displacement absorbing member 5 as the displacement of the object 3. On the other hand, when a strong impact is applied to the hull 2 and the shock absorbing member 6 collides with the object 3, the impact is absorbed by the shock absorbing member 6. Since the shock absorbing member 6 is located on the side of the displacement absorbing member 5 in each of the first to third support portions 11 to 13, the distance from the hull 2 to the object 3 at each support position should be shortened. Can be done.

Moreover, when the shock absorbing member 6 is plastically deformed, the shock absorbing function of the support structure 1 can be restored simply by replacing the shock absorbing member 6.

(Modification example)
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

For example, the displacement absorbing member 5 and the shock absorbing member 6 do not necessarily have to be provided on the hull 2 via a common support base 4, and may be provided on the hull 2 via separate support bases. However, if the displacement absorbing member 5 and the shock absorbing member 6 are provided on the hull 2 via a common support base 4 as in the above embodiment, the support structure 1 can be simplified.

Further, the shock absorbing member 6 may be provided on the object 3 as shown in FIG. 7. Even in this case, the gap H between each shock absorbing member 6 and the support base 4 in the direction orthogonal to the upper surface of the shock absorbing member 6 (when the displacement absorbing member 5 is directly provided on the hull 2, each shock absorbing member 6 The gap H) between the hull and the hull 2 is set so as to satisfy the above equation 1.

Alternatively, as shown in FIG. 8, the displacement absorbing member 5 may be provided on the object 3 via the support base 4, or may be provided directly on the object 3 without the support base 4. .. When the displacement absorbing member 5 is provided on the object 3 via the support 4, the shock absorbing member 6 is provided on the support 4, and when the displacement absorbing member 5 is directly provided on the object 3, the shock absorbing member 6 is also provided on the object 3. Even in these cases, the gap H between each shock absorbing member 6 and the hull 2 in the direction orthogonal to the upper surface of the shock absorbing member 6 is set so as to satisfy the above-mentioned equation 1.

Further, as shown in FIG. 9, the displacement absorbing member 5 may be provided on the object 3 directly or via the support base 4, and the shock absorbing member 6 may be provided on the hull 2. Even in this case, the gap H between each shock absorbing member 6 and the support base 4 in the direction orthogonal to the upper surface of the shock absorbing member 6 (when the displacement absorbing member 5 is directly provided on the object 3, each shock absorbing member is provided. The gap H) between 6 and the object 3 is set so as to satisfy the above-mentioned equation 1.
