Description

Technical Field

[0001] The present invention relates in particular to a watertight transverse bulkhead and a cruise ship hub containing the same. Background Technology

[0002] A cruise ship hub is a super-large mothership capable of accommodating two cruise ships, typically exceeding 500 meters in length. Because ample space must be left on both sides of the hull for berthing vessels, the transverse and longitudinal bulkheads are the most crucial supports for the hull beams, in addition to the main deck and outer plating. Currently, ships lack such a large scale, and aside from the longitudinal bulkheads, they already possess sufficient strong transverse structural members for support. However, the main body of a hub ship is concave in the middle of its beam direction and needs to accommodate ballast tanks and activity space, leaving insufficient space for a sufficiently strong transverse frame. Therefore, a transverse bulkhead design of sufficient strength is required to meet the overall structural strength requirements of the ship. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiency of insufficient strength of the transverse bulkhead structure in the prior art, and to provide a watertight transverse bulkhead and a cruise ship hub including the same.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A watertight transverse bulkhead, wherein the watertight transverse bulkhead is disposed between the main deck and the inner bottom plate, the watertight transverse bulkhead comprising:

[0006] A first support portion is disposed between the main deck and the inner bottom plate. The first support portion extends from the main deck to the inner bottom plate and is perpendicular to the main deck and the inner bottom plate. The cross-sectional width of the area of ​​the first support portion near the main deck is smaller than the cross-sectional width of the area of ​​the first support portion away from the main deck.

[0007] A connecting part is provided, which is perpendicularly connected to the first support part, and multiple connecting parts are provided along the direction from the main deck to the inner bottom plate.

[0008] In this design, a first support section is constructed to form the main body of the transverse bulkhead and effectively support the space between the main deck and the inner bottom plate. The cross-sectional width of the first support section near the main deck is smaller than that of the section away from the main deck, which can effectively transfer the non-uniformly distributed load transmitted from different areas of the main deck. In addition, it can reduce the still water bending moment of the hull beams, reduce the overall structural weight of the ship, and effectively control the deformation of the hull beams.

[0009] Preferably, five first support portions are provided, and the five first support portions are arranged side by side and fit together with each other;

[0010] Or five of the first support parts are arranged side by side and spaced apart from each other.

[0011] In this design, the torsional strength of the transverse bulkhead is improved by increasing the number of first support components as described above. Furthermore, whether the first support components are fitted together or spaced apart, the structural strength of the transverse bulkhead can be guaranteed.

[0012] Preferably, the cross-sectional width of the first support gradually increases from the main deck to the inner bottom plate.

[0013] In this scheme, the above-mentioned arrangement enhances the structural strength of the middle area of ​​the first support section, thereby overcoming the problem that the hub station with an inwardly concave trend in the middle has ballast tanks and activity space in the direction of the ship's width but no space to arrange a strong transverse frame with strong support, thus improving the structural strength of the transverse bulkhead.

[0014] Preferably, in the direction from the main deck to the inner bottom plate, the cross-sectional width of the end of the first support near the main deck and the end of the first support near the inner bottom plate is smaller than the cross-sectional width of the middle region of the first support.

[0015] In this scheme, by setting the cross-sectional width at both ends of the first support, i.e., the area near the main deck and the inner bottom plate, smaller than the cross-sectional width of the middle area of ​​the first support, it can also overcome the problem that the hub station with the concave trend in the middle has ballast tanks and activity space in the direction of the ship's width but no space to arrange a strong transverse frame with strong support, thereby improving the strength of the transverse bulkhead structure.

[0016] Preferably, the number of the connecting portions gradually increases and the spacing between the connecting portions gradually decreases from the direction from the main deck to the inner bottom plate.

[0017] In this scheme, by gradually increasing the number of connecting parts through the above-mentioned arrangement, the center of gravity of the transverse bulkhead is kept in an appropriate position, avoiding a high center of gravity.

[0018] Preferably, the connecting portion includes a web, the height of which gradually increases from the main deck to the inner bottom plate.

[0019] In this solution, the above settings are used to lower the center of gravity while ensuring torsional strength.

[0020] Preferably, the watertight transverse bulkhead further includes a second support portion, which is disposed on the side of the connection between the first support portion and the inner bottom plate and is connected to the first support portion and the inner bottom plate. The second support portion has a triangular structure.

[0021] In this solution, the above-mentioned settings are used to improve the stability of the connection between the first support and the inner bottom plate, and to prevent the first support from tilting under stress.

[0022] Preferably, the watertight transverse bulkhead further includes a third support portion, which is disposed on the side of the connection between the first support portion and the main deck and is connected to the first support portion and the main deck. The third support portion has a triangular structure.

[0023] In this solution, the above-mentioned settings are used to improve the stability of the connection between the first support and the main deck, and to prevent the first support from tilting under stress.

[0024] Preferably, the third support portion has a weight-reducing hole, which is located away from the connection between the first support portion and the main deck.

[0025] In this scheme, the above-mentioned arrangement is used to reduce the weight of the third support and reduce the weight of the transverse bulkhead structure while ensuring the stability of the connection between the first support and the main deck.

[0026] A cruise ship hub, the cruise ship hub including the watertight transverse bulkheads as described above.

[0027] In this design, the cruise ship hub includes the aforementioned watertight transverse bulkheads to reduce the static bending moment of the hull beams, reduce the overall structural weight of the ship, and effectively control the deformation of the hull beams. In the case of limited space where it is not possible to install strong transverse frames with strong supports, the structural strength requirements of the entire ship structure and the transverse bulkheads are met.

[0028] The positive and progressive effects of this invention are as follows: By setting a first support part, the invention forms the main body of the transverse bulkhead and effectively supports the space between the main deck and the inner bottom plate. The cross-sectional width of the first support part near the main deck is smaller than the cross-sectional width of the first support part away from the main deck, which can effectively transfer the non-uniformly distributed load transmitted from different areas of the main deck. In addition, it can reduce the still water bending moment of the hull beams, reduce the overall structural weight of the ship, and effectively control the deformation of the hull beams.

[0040] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0041] This embodiment provides a watertight transverse bulkhead, the specific structure of which is as follows: Figure 1 , Figure 2 and Figure 3 As shown, a watertight transverse bulkhead is located between the main deck 1 and the inner bottom plate 2, and the watertight transverse bulkhead includes:

[0042] The first support part 3 is disposed between the main deck 1 and the inner bottom plate 2. The first support part 3 extends from the main deck 1 to the inner bottom plate 2 and is perpendicular to the main deck 1 and the inner bottom plate 2. The cross-sectional width of the area of ​​the first support part 3 near the main deck 1 is smaller than the cross-sectional width of the area of ​​the first support part 3 away from the main deck 1.

[0043] The connecting part 4 is vertically connected to the first support part 3, and multiple connecting parts 4 are provided along the direction from the main deck 1 to the inner bottom plate 2.

[0044] Specifically, the first support part 3 is a square steel column in the prior art, and the connecting part 4 is a horizontal truss in the prior art. The direction from the main deck 1 to the inner bottom plate 2 is the height direction of the transverse bulkhead. In this embodiment, the first support part 3 extends along the height direction of the transverse bulkhead. One end of the first support part 3 is vertically connected to the bottom of the main deck 1, and the other end of the first support part 3 is vertically connected to the inner bottom plate 2. The first support part 3 is used to construct the main body of the transverse bulkhead and effectively support the space between the main deck 1 and the inner bottom plate 2. The connecting part 4 is connected to the first support part 3 along the height direction perpendicular to the transverse bulkhead. The connecting part 4 is used to adjust the height of the center of gravity of the first support part 3 and to improve the load-bearing capacity of the first support part 3 in the height direction perpendicular to the transverse bulkhead.

[0045] In this embodiment, the cross-sectional width of the first support part 3 is not uniform. The cross-sectional width is smaller near the main deck 1, meaning the end of the first support part 3 connecting to the main deck 1 has a smaller cross-sectional dimension, while the cross-sectional dimension of the first support part 3 further away from the main deck 1 is larger than the end of the first support part 3 connecting to the main deck 1. This allows the first support part 3 to effectively transfer the non-uniformly distributed load transmitted from different areas of the main deck 1. When using transverse bulkheads for cruise ship hubs, since the ship's beam direction is concave towards the center, the non-uniform cross-sectional width of the first support part 3 overcomes the deficiency of not having space to install transverse reinforcing frames. Furthermore, the first support part 3 in this embodiment can reduce the still water bending moment of the hull beams in the cruise ship hub, reduce the overall structural weight of the ship, and effectively control the deformation of the hull beams.

[0046] In this embodiment, five first support parts 3 are provided, and the five first support parts 3 are arranged side by side and fit together.

[0047] Specifically, the five first support parts 3 arranged side by side fit together, and multiple connecting parts 4 are vertically connected to the five first support parts 3 in sequence, so as to connect the five first support parts 3 arranged side by side through the connecting parts 4 to form an integral structure, thereby increasing the torsional strength of the transverse bulkhead by increasing the number of first support parts 3.

[0048] In another embodiment, five first support parts 3 are arranged side by side and spaced apart from each other, and the spaced arrangement can also ensure the structural strength of the transverse bulkhead.

[0049] In this embodiment, the cross-sectional width of the first support portion 3 gradually increases in the direction from the autonomous deck 1 to the inner bottom plate 2.

[0050] Specifically, along the height direction of the transverse bulkhead, the cross-sectional width of the first support part 3 closest to the main deck 1 is the smallest, while the cross-sectional width of the first support part 3 away from the main deck 1 and towards the inner bottom plate 2 gradually increases from top to bottom. This enhances the structural strength of the middle area of ​​the first support part 3, overcomes the problem that the hub station with the concave trend in the middle has ballast tanks and activity space in the direction of the ship's width but no space to arrange a strong transverse frame, and thus improves the structural strength of the transverse bulkhead.

[0051] In another embodiment, in the direction from the main deck 1 to the inner bottom plate 2, the cross-sectional width of the first support portion 3 near the end of the main deck 1 and the end of the first support portion 3 near the inner bottom plate 2 is smaller than the cross-sectional width of the middle region of the first support portion 3.

[0052] Specifically, along the height direction of the transverse bulkhead, the cross-sectional width of the first support part 3 near the main deck 1 and the cross-sectional width of the first support part 3 near the inner bottom plate 2 are the smallest, while the cross-sectional width of the middle area of ​​the first support part 3 is the largest, forming a "small-large-small" pattern from top to bottom. That is, the cross-sectional width at both ends of the first support part 3 is set smaller than the cross-sectional width of the middle area of ​​the first support part 3. This can also overcome the problem that the hub station with an inward trend in the middle has ballast tanks and activity space in the direction of the ship's beam, but there is no space to arrange a strong transverse frame with strong support, thereby improving the structural strength of the transverse bulkhead.

[0053] It is understandable that the cross-sectional width of the first support part 3 near the inner bottom plate 2 can be greater than the cross-sectional width of the first support part 3 near the main deck 1. At the same time, the cross-sectional width of the first support part 3 near the inner bottom plate 2 is smaller than the cross-sectional width of the middle area of ​​the first support part 3.

[0054] In this embodiment, the number of connecting parts 4 gradually increases and the spacing between the connecting parts 4 gradually decreases in the direction from the autonomous deck 1 to the inner bottom plate 2.

[0055] Specifically, multiple connecting parts 4 are arranged from top to bottom along the height direction of the transverse bulkhead. Each connecting part 4 is perpendicularly connected to five first support parts 3, and the spacing between the connecting parts 4 is not uniform. In the area of ​​the first support part 3 near the main deck 1, the spacing between adjacent connecting parts 4 is large and the number is small. In the middle area of ​​the first support part 3, the spacing between adjacent connecting parts 4 is small and the number increases. Simultaneously, in the area of ​​the first support part 3 near the inner bottom plate 2, the spacing between adjacent connecting parts 4 is even smaller and the number is the largest. This is smaller than the spacing between adjacent connecting parts 4 in the areas of the first support part 3 near the main deck 1 and in the middle area of ​​the first support part 3, but larger than the number of connecting parts 4 in the areas of the first support part 3 near the main deck 1 and in the middle area of ​​the first support part 3. This ensures that the center of gravity of the transverse bulkhead is maintained in an appropriate position, preventing it from being too high.

[0056] In this embodiment, the connecting part 4 includes a web (not shown in the figure), and the height of the web gradually increases in the direction from the main deck 1 to the inner bottom plate 2.

[0057] Specifically, as the web extends from the height of the transverse bulkhead, the number of connecting parts 4 gradually increases and the spacing between the connecting parts 4 gradually decreases from the main deck 1 to the inner bottom plate 2. In the area of ​​the first support 3 near the main deck 1, the height of the web is small, while in the middle area of ​​the first support 3, the height of the web is relatively high. At the same time, in the area of ​​the first support 3 near the inner bottom plate 2, the height of the web is the highest. This is to lower the center of gravity while ensuring the torsional strength of the transverse bulkhead.

[0058] In this embodiment, the watertight transverse bulkhead also includes a second support portion 5. The second support portion 5 is disposed on the side of the connection between the first support portion 3 and the inner bottom plate 2 and is connected to the first support portion 3 and the inner bottom plate 2. The second support portion 5 has a triangular structure.

[0059] Specifically, the second support 5 is an elbow plate, with one side of the elbow plate having a right-angle structure to tightly connect with the mutually perpendicular first support 3 and inner bottom plate 2. The side of the elbow plate away from the connection between the first support 3 and inner bottom plate 2 has an arc-shaped structure, which provides greater structural strength compared to the straight side of the elbow plate away from the connection between the first support 3 and inner bottom plate 2. Multiple second support 5s are provided and located around the periphery of the first support 3. By providing the second support 5s, the stability of the connection between the first support 3 and inner bottom plate 2 is improved, preventing the first support 3 from tilting under stress.

[0060] In this embodiment, the watertight transverse bulkhead also includes a third support portion 6, which is located on the side of the connection between the first support portion 3 and the main deck 1 and is connected to the first support portion 3 and the main deck 1. The third support portion 6 has a triangular structure.

[0061] Specifically, the third support 6 is an elbow plate, with one side of the elbow plate having a right-angle structure to be tightly connected to the mutually perpendicular first support 3 and main deck 1. The side of the elbow plate away from the connection between the first support 3 and the main deck 1 has a straight side. Multiple third support 6s are provided and located around the periphery of the first support 3. By providing the third support 6s, the stability of the connection between the first support 3 and the main deck 1 is improved, preventing the first support 3 from tilting under force.

[0062] Furthermore, in this embodiment, a weight-reducing hole 61 is provided on the third support part 6, and the weight-reducing hole 61 is located away from the connection between the first support part 3 and the main deck 1.

[0063] Specifically, the weight reduction hole 61 penetrates the third support part 6. By setting the weight reduction hole 61, the weight of the third support part 6 is reduced, thereby reducing the weight of the transverse bulkhead structure. In addition, the weight reduction hole 61 is set away from the connection between the first support part 3 and the main deck 1 to ensure the load-bearing performance of the third support part 6 near the connection between the first support part 3 and the main deck 1, as well as the stability of the connection between the first support part 3 and the main deck 1.

[0064] This embodiment also provides a cruise ship hub station, which includes the aforementioned watertight transverse bulkhead. The watertight transverse bulkhead has a simple structure, high safety, and flexible configuration. It can effectively reduce the static water bending moment of the hull beams, reduce the overall structural weight of the ship, and effectively control the deformation of the hull beams. In the case where a strong transverse frame with strong support cannot be set in a limited space, it can meet the structural strength requirements of the entire ship structure and the transverse bulkhead.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
