Description

Technical Field

[0001] This utility model relates to the field of ship technology, specifically to a ship hull. Background Technology

[0002] With the increasing demand for longer voyages, aluminum alloy hulls are gradually replacing steel hulls. Since the hull is a hollow structure, the material properties are put to a great strain. To address this, stiffeners are added to the bulkheads. However, these stiffeners are perpendicular to the hull's length (longitudinal direction) and extend in the same direction as the hull's width (transverse direction). Therefore, the hull cannot be directly manufactured by extruding aluminum. Typically, hulls are produced by transversely extruding stiffened plates and then welding them together with extruded aluminum flat plates. This method increases the welding process, the number of welds, and the number of steps, thus impacting production time and efficiency. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is combined Figures 1 to 3 The hull 1000 of this utility model embodiment is described below.

[0026] like Figures 1 to 3As shown, the hull 1000 of this embodiment includes a hull shell 1 and a reinforcing structure 2. The hull shell 1 is a one-piece molded metal part, meaning the hull 1000 is directly processed from metal profiles, such as by direct extrusion molding, into a one-piece molded part. This eliminates the need for welding, reducing weld seams on the hull 1000, and also facilitates processing, resulting in fast processing speed and high efficiency. However, the hull shell 1 lacks a ribbed structure, and its strength may not meet design strength requirements.

[0027] The reinforcing structure 2 is a friction stir additive component deposited on the inner surface of the hull 1. That is, the reinforcing structure 2 is directly deposited on the inner surface of the hull 1 using the friction stir additive method. On the one hand, it enhances the overall structural strength of the hull 1000 and can meet the design strength requirements. On the other hand, it does not require welding, reducing the number of welds on the hull 1000. Furthermore, it is easy to process, fast to process, and has high processing efficiency.

[0028] The hull 1000 of this utility model embodiment has the following advantages: the overall structural strength of the hull 1000 is high, which can meet the design strength requirements; the welding process is reduced, and there are fewer welds; it is easy to process, the processing speed is fast, the processing efficiency is high, and the application prospects are broad.

[0029] In some embodiments, the hull 1 is an integrally extruded part. That is, the hull 1 is obtained by extrusion molding, which does not require welding, is convenient to process, fast to process, and has high processing efficiency.

[0030] In some embodiments, the hull 1 is an aluminum alloy hull. That is, the hull 1 is directly extruded from aluminum alloy profiles, and this aluminum alloy hull is the hull 1. However, this hull 1 does not have a ribbed structure, has low strength, and does not meet the design strength requirements. The hull 1 is obtained by extruding aluminum alloy profiles, which eliminates the need for welding, reducing welds on the hull 1000, and also facilitates processing, with fast processing speed and high processing efficiency.

[0031] In some embodiments, the hull 1 is formed by connecting multiple flat plates. For example, the bottom flat plate of the hull 1 is connected to each of the side flat plates, and the side flat plates are connected end to end in sequence. In this way, it can be formed by extrusion molding using metal profiles. On the one hand, welding is not required, reducing the number of welds on the hull 1000. On the other hand, it is easy to process, fast to process, and has high processing efficiency. However, the hull 1 does not have a ribbed structure, and its strength may not meet the design strength requirements.

[0032] In some embodiments, the reinforcing structure 2 is a reinforcing rib. The reinforcing rib can improve the overall structural strength of the hull 1000, enabling the overall structural strength of the hull 1000 to meet the design requirements; and the reinforcing rib can be directly deposited on the surface of the hull 1 by friction stirring additive manufacturing, without the need for additional welding processes, reducing the number of welds on the hull 1000, and resulting in high processing efficiency.

[0033] In some embodiments, the stiffener is a stiffening plate. The stiffening plate can effectively improve the overall structural strength of the hull 1000, enabling the overall structural strength of the hull 1000 to meet the design requirements; and the stiffening plate can be directly deposited on the surface of the hull 1 by friction stirring additive manufacturing, without the need for additional welding processes, reducing the number of welds on the hull 1000, and resulting in high processing efficiency.

[0034] In some embodiments, the stiffeners include transverse stiffeners 201, which extend along the width direction of the hull 1. The transverse stiffeners 201 can effectively improve the overall structural strength of the hull 1000, ensuring that the overall structural strength of the hull 1000 meets the design requirements; moreover, the transverse stiffeners 201 can be directly deposited on the surface of the hull 1 by friction stir additive manufacturing, eliminating the need for additional welding processes, reducing welds on the hull 1000, and resulting in high processing efficiency.

[0035] In some embodiments, the two ends of the transverse stiffeners 201 extend to the upper ends of both sides of the hull 1. This can better improve the overall structural strength of the hull 1000.

[0036] In some embodiments, there are one or more transverse stiffeners 201, wherein the transverse stiffeners 201 are spaced apart. The number of transverse stiffeners 201 can be determined according to actual needs.

[0037] In some embodiments, the widths of the plurality of transverse stiffeners 201 may be the same or different, and the thicknesses of the plurality of transverse stiffeners 201 may be the same or different. The width and thickness of the plurality of transverse stiffeners 201 can be determined according to actual needs.

[0038] In some embodiments, in addition to transverse stiffeners 201, stiffeners may also include non-transverse stiffeners 201, such as longitudinal stiffeners, or stiffeners in other directions, with the main purpose of further improving the structural strength of the hull 1000.

[0039] like Figures 2 to 3 As shown, the following is a method for manufacturing the hull 1000 according to an embodiment of this utility model. The specific steps are as follows:

[0040] S1: As Figure 2 As shown, the hull is first extruded directly from aluminum alloy profiles.

[0041] In step S1, the hull 1 is obtained by extrusion molding, which eliminates the need for welding, reducing the number of welds on the hull 1000, and is easy to process, fast to process, and has high processing efficiency; however, the hull 1 does not have a rib structure and has low strength.

[0042] S2: As Figure 3 As shown, a transverse stiffener 201 is deposited on the inner surface of the ship's hull 1 using a friction stir additive manufacturing spindle 3. The material of the transverse stiffener 201 is a metallic material. Because the material produced by friction stir additive manufacturing has high strength, it can be used directly. However, for special industries where it is necessary to further increase the strength of aluminum alloy, a heat treatment device 4 that moves in the same direction can be added after the friction stir additive manufacturing spindle 3. This allows for simultaneous deposition of the aluminum alloy transverse stiffener 201 and heat treatment of the newly deposited aluminum alloy transverse stiffener 201, thus achieving timely heat treatment of the newly deposited aluminum alloy transverse stiffener 201 and further increasing its strength. The heat treatment apparatus 4 includes a heating module 401 and a cooling module 402. The heating module 401 is arranged adjacent to the rear of the friction stir additive manufacturing spindle 3, and the cooling module 402 is arranged adjacent to the rear of the heating module 401. The heating method of the heating module 401 can be flame heating, high-frequency heating, electric arc heating, or laser heating, while the cooling method of the cooling module 402 can be water cooling, oil cooling, liquid nitrogen cooling, or other media cooling. For different heat treatment parameters of the aluminum alloy transverse stiffeners 201, the number of heating modules 401 and cooling modules 402 can be increased to verify the time and effect of solution treatment and aging.

[0043] In step S2, the transverse stiffener 201 is directly deposited on the inner surface of the hull 1 using friction stir additive manufacturing. This enhances the overall structural strength of the hull 1000 and meets the design strength requirements. Furthermore, it eliminates the need for welding, reducing the number of welds on the hull 1000. Additionally, it is easy to process, fast to process, and has high processing efficiency.
