Description

Technical Field

[0001] The present invention belongs to the technical field of ships, and particularly relates to a design method for a curved bulkhead and a curved bulkhead. Background Art

[0002] During the ship design process, in order to pursue a larger internal space, aesthetic appearance, and design artistry, it is usually inclined to arrange some curved bulkheads. Such bulkheads usually appear on the periphery of the superstructure or inside the cabins. Therefore, a relatively large number of installation holes are usually arranged on the bulkheads according to usage requirements for installing windows or ventilation devices such as ventilation grilles. However, when opening installation holes in the existing curved bulkheads, the following problems are faced. When there are a large number of installation holes, due to the irregular shape of the curved bulkhead, the shape of each installation hole is basically different, which in turn leads to different shapes of the windows or ventilation grilles installed in the installation holes. Basically, there are as many shapes as there are windows. The existing curved bulkheads cannot open the same installation holes. On the other hand, it will significantly increase the production cycle and production cost of the windows or ventilation grilles because they have different shapes and cannot be produced with a set of drawings and molds. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a design method for a curved bulkhead.

[0004] The present invention provides a design method for a curved bulkhead, which includes the following steps:

[0005] Form a bulkhead model to be perforated according to requirements. The bulkhead model to be perforated is formed by rotating the quadrilateral ABCD around the rotation axis OO1 by an angle α to A1B1C1D1, where AB∥CD, AB = CD, and AB and CD are respectively perpendicular to OO1. AC is closer to OO1 than BD, and the distance from A to OO1 is not equal to the distance from C to OO1;

[0006] According to the perforation requirements, divide the bulkhead model to be perforated into n parts to be perforated areas at intervals of (α / n) angles. The to-be-perforated areas are provided with installation holes that penetrate the inner and outer surfaces of the bulkhead model to be perforated and have the same shape and size. The installation holes and the to-be-perforated areas are similar figures. One installation hole is opened in each to-be-perforated area. The upper surfaces of each installation hole are on the same plane, the lower surfaces of each installation hole are on the same plane, and the upper and lower surfaces of each installation hole are respectively parallel to the ABA1B1 plane;

[0007] The target bulkhead is formed by opening the installation holes in the bulkhead model to be perforated, where the length of AB is the thickness of the target bulkhead. The planes ABCD and A1B1C1D1 are respectively the left end face and the right end face of the target bulkhead. The quadrilaterals ABA1B1 and CDC1D1 are respectively the lower end face and the upper end face of the target bulkhead. The curved surfaces ACA1C1 and BDB1D1 are respectively the inner wall curved surface and the outer wall curved surface of the target bulkhead.

[0008] Preferably, the cross-sections of the installation holes and the areas to be perforated are both trapezoidal. The center of the installation hole is located at the center of the area to be perforated. The area to be perforated also forms a reinforcing installation frame, and the reinforcing installation frame is located on the outer periphery of the installation hole.

[0009] Preferably, when forming the bulkhead model to be perforated according to requirements, the bulkhead model to be perforated is formed by the upper edge line, the lower edge line, the left edge line and the right edge line of the bulkhead.

[0010] When according to the perforation requirements, according to the total area of the perforations and the total area of the strong installation ends, the bulkhead model to be perforated is equally divided into n areas to be perforated at intervals of (α / n) angles.

[0011] Preferably, multiple bulkhead models to be perforated are formed according to requirements. According to the perforation requirements, each bulkhead model to be perforated is equally divided into n areas to be perforated at intervals of (α / n) angles. The target bulkhead is formed by combining multiple bulkhead models to be perforated.

[0012] Preferably, the distance from A to OO1 is greater than the distance from C to OO1.

[0013] On the other hand, the present application provides a curved bulkhead. The curved bulkhead includes a target bulkhead formed by the design method of the above-mentioned curved bulkhead, and the target bulkhead is provided with installation holes.

[0014] Preferably, the curved bulkhead further includes a reinforcing installation frame formed on the target bulkhead and reinforcing ribs connected to the reinforcing installation frame. The reinforcing installation frame is located on the outer periphery of the installation hole. The installation hole is used for installing windows and ventilation devices. One end of the reinforcing rib far away from the reinforcing installation frame is connected to the hull, and the reinforcing rib is used to support the curved bulkhead.

[0015] The design method of the curved bulkhead and the curved bulkhead provided by the present invention. Since the curved ship wall of the present application is a part of a cone and has the characteristics of a conical curved surface, the target bulkhead can be evenly divided into multiple areas to be perforated. Each area to be perforated can be provided with an installation hole, and the sizes and shapes of the installation holes are the same. Furthermore, it is ensured that the windows or ventilation grilles on the bulkhead can achieve the same specifications, thereby greatly reducing the production cost and cycle of the windows or ventilation grilles. At the same time, using a similar conical curved surface can have the aesthetic degree of its complex curved surface. Description of the Drawings

[0023] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element at the same time. The terms "mounted", "one end", "the other end", and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this technology belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] The present invention provides a design method for a curved bulkhead, which includes the following steps:

[0027] According to requirements, a bulkhead model 100 to be perforated is formed. The bulkhead model 100 to be perforated is formed by rotating the quadrilateral ABCD around the rotation axis OO1 by an angle α to A1B1C1D1, where AB∥CD, AB = CD, and AB and CD are respectively perpendicular to OO1, AC is closer to OO1 than BD, and the distance from A to OO1 is not equal to the distance from C to OO1; according to the perforation requirements, the bulkhead model 100 to be perforated is equally divided into n parts of perforation regions at intervals of (α / n) angles. The perforation regions are provided with mounting holes 201 that penetrate the inner and outer surfaces of the bulkhead model 100 and have the same shape and size. The mounting holes 201 and the perforation regions are similar figures. One mounting hole 201 is provided in each perforation region. The upper surfaces of each mounting hole 201 are in the same plane, the lower surfaces of each mounting hole 201 are in the same plane, and the upper and lower surfaces of each mounting hole 201 are respectively parallel to the ABA1B1 plane; the target bulkhead 200 is formed by perforating the mounting holes 201 in the bulkhead model 100 to be perforated. The length of AB is the thickness of the target bulkhead 200. The planes ABCD and A1B1C1D1 are respectively the left and right end faces of the target bulkhead 200. The quadrilaterals ABA1B1 and CDC1D1 are respectively the lower and upper end faces of the target bulkhead 200. The curved surfaces ACA1C1 and BDB1D1 are respectively the inner wall curved surface and the outer wall curved surface of the target bulkhead 200.

[0028] When designing the target bulkhead 200, the bulkhead model 100 to be perforated is formed by calculating through the upper, lower, left, and right side lines of the bulkhead. Then, according to the total perforation area (the area referred to in this application is the area located on the curved surface BDB1D1) and the total area of the strong installation ends, the bulkhead model 100 to be perforated is equally divided into n parts of perforation regions at intervals of (α / n) angles. For example, by calculating that the total area of the required mounting holes 201 is 500 square meters and the total area of the strong installation ends is 100 square meters, and the area of each mounting hole 201 is 50 square meters, the bulkhead model 100 to be perforated is divided into 10 parts. When α = 100°, starting from the initial position, the quadrilateral ABCD rotates the bulkhead model 100 to separate a perforation region every 10°. Finally, the bulkhead model 100 to be perforated is separated into 10 identical perforation regions. Since these 10 perforation regions have the same shape and size and are all part of a cone, they have the characteristics of a cone and at the same time have the characteristics of a rotating body. When ensuring that the heights of the upper and lower ends are the same during the perforation of the mounting holes 201 in the perforation regions, the left and right ends of the mounting holes 201 are intercepted according to the ABCD rotation plane. When intercepted by the ABCD rotation plane and the rotation angles are the same, the shape and size of each mounting hole 201 are the same.

[0029] In a preferred embodiment, the cross-section of the mounting hole 201 and the cross-section of the area to be drilled are both trapezoidal. The center of the mounting hole 201 is located at the center of the area to be drilled. The area to be drilled further forms a reinforcing mounting frame 202, and the reinforcing mounting frame 202 is located on the outer periphery of the mounting hole 201. The center of the mounting hole 201 being located at the center of the area to be drilled is more conducive to generating processing. The reinforcing mounting frame 202 can strengthen the workpiece mounted in the mounting hole 201. The strong mounting frame is further used to connect the reinforcing ribs to strengthen and fix the curved bulkhead.

[0030] In a preferred embodiment, the target bulkhead 200 is formed by combining a plurality of bulkhead models 100 to be drilled. For example, two bulkhead models 100 to be drilled are spliced together. Please refer to Figure 1 , the target bulkhead 200 is formed by splicing two identical bulkhead models 100 to be drilled. When splicing, one of them is inverted so that its ABCD plane is connected to the other A1B1C1D1 plane; the mounting holes 201 opened between the two bulkhead models 100 to be drilled can be the same or different. Further, the distance from A to OO1 is greater than the distance from C to OO1.

[0031] On the other hand, the present application provides a curved bulkhead. The curved bulkhead includes the target bulkhead 200 formed by the design method of the above-mentioned curved bulkhead, and the target bulkhead 200 is provided with a mounting hole 201. Further, the curved bulkhead further includes a reinforcing mounting frame 202 formed on the target bulkhead 200 and a reinforcing rib connected to the reinforcing mounting frame 202. The reinforcing mounting frame 202 is located on the outer periphery of the mounting hole 201. The mounting hole 201 is used to install windows and ventilation devices. The end of the reinforcing rib away from the reinforcing mounting frame 202 is connected to the hull, and the reinforcing rib is used to support the curved bulkhead.

[0032] The design method of the curved bulkhead and the curved bulkhead provided by the present invention. Since the curved ship wall of the present application is a part of a cone and has the characteristics of a conical surface, the target bulkhead can be evenly divided into a plurality of areas to be drilled, and each area to be drilled can be provided with a mounting hole. The size and shape of the mounting holes are the same, thereby ensuring that the windows or ventilation grilles on the bulkhead can achieve the same specification, thus greatly reducing the production cost and cycle of the windows or ventilation grilles; at the same time, using a similar conical surface can have the aesthetic degree of its complex surface, and can avoid the poor aesthetic degree and dullness of a cylindrical surface. Another advantage of the present invention is that the conical surface is a single curved surface. Compared with other complex curved bulkhead plates, the processing and production of its bulkhead plates are simpler, and the stiffeners on the bulkhead are straight and do not need to be processed. Therefore, the production cost and cycle of the bulkhead are also lower.

[0033] In this application, unless otherwise clearly stipulated or limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the horizontal height of the first feature is less than that of the second feature.
