Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a ship transverse channel and a manufacturing method thereof. Background Art

[0002] like Figure 1 As shown, the ship includes a U-shaped tank or a structure similar to the U-shaped tank. The U-shaped tank includes cabins 100' located on both sides and a transverse passage 200' connected between the cabins 100' on both sides. The heights of the cabins 100' on both sides are higher, and the height of the transverse passage 200' is lower. Once one side of the U-shaped tank is damaged, if the volume of water entering per unit time is large, it will take a certain amount of time for water to pass from the cabin 100' on one side through the transverse passage 200' into the cabin 100' on the other side, resulting in unequal volumes of water entering the cabins 100' on both sides per unit time, causing a very large roll during the water entering process, i.e., transverse water entering.

[0003] In the prior art, Figure 2-Figure 4 As shown, transverse passage 200' includes at least one passage 201' surrounded by wall panels 202'. Reinforcement ribs 300' made of flat iron 301' or bulb flat steel 302' are installed on the inner side of passage 201' to ensure structural strength. However, the reinforcement ribs 300' occupy the internal space of passage 201', reducing the net flow area of ​​passage 201' and lowering water flow efficiency, thereby increasing the roll of cabin 100' and poor transverse stability. Summary of the Invention

[0004] The purpose of the present invention is to provide a ship transverse channel and a manufacturing method thereof, so as to increase the flow area of ​​the channel to improve the water flow efficiency and enhance the transverse stability.

[0036] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0038] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0039] This embodiment provides a ship traversing channel, such as Figure 5-Figure 8 As shown, it includes a wall panel unit 1 and a reinforcing rib 2. The wall panel unit 1 includes a first side panel 11 and a side panel assembly 12. The end of the first side panel 11 is connected to the side panel assembly 12. The first side panel 11 and the side panel assembly 12 are arranged to form a channel 1A. The first side panel 11 includes a plurality of mounting plates 111. The plurality of mounting plates 111 are arranged along the length direction of the channel 1A; the reinforcing rib 2 includes a protruding portion 21 and a connecting portion 22. The connecting portion 22 connects two adjacent mounting plates 111. The end of the connecting portion 22 is connected to the side panel assembly 12, and the protruding portion 21 protrudes into the channel 1A.

[0040] The two ends of the reinforcing rib 2 are connected to the side panel assembly 12 and the two sides are connected to the mounting plate 111. In other words, the reinforcing rib 2 connects the mounting plate 111 and the side panel assembly 12, improving the stability and reliability of the connection. By positioning the connecting portion 22 between the two mounting plates 111, with only the protruding portion 21 located within the channel 1A, the reinforcing rib 2 reduces the space occupied by the channel 1A while meeting the structural strength requirements, increasing the net flow area of ​​the channel 1A, reducing water flow resistance, and improving water flow efficiency. In the event of cross-ingress of water, it reduces cabin roll and improves transverse stability.

[0041] In one embodiment, if Figure 5-Figure 8 As shown, two side panel assemblies 12 are provided, with a first side panel 11 disposed between the two side panel assemblies 12 to form two channels 1A. The reinforcing rib 2 includes two protrusions 21 disposed on either side of the connecting portion 22, with the two protrusions 21 disposed within the two channels 1A. The reinforcing rib 2 is disposed on the first side panel 11 shared by both channels 1A, eliminating the need to install the reinforcing rib 2 separately in each channel 1A, simplifying the structure and easing the assembly steps. Furthermore, compared to existing structures, while maintaining the same cross-sectional dimensions, the space occupied by the reinforcing rib 2 on a single channel 1A is further reduced, increasing the net flow area of ​​both channels 1A, thereby further improving the water flow efficiency within the channel 1A.

[0042] The cross-sectional shape of the channel 1A is not limited and can be set according to actual conditions.

[0043] In the first embodiment, the side panel assembly 12 can include only one plate, and the shapes of the first side panel 11 and the side panel assembly 12 themselves are not limited. One can be a flat plate and the other can be an arc-shaped plate, or both can be arc-shaped plates. It is sufficient to ensure that the side panel assembly 12 and the first side panel 11 can be enclosed to form the channel 1A. The reinforcement rib 2 can be adaptively set according to the shape of the first side panel 11, and both ends of the reinforcement rib 2 are connected to the side panel assembly 12.

[0044] In the second embodiment, the side panel assembly 12 includes a second side panel 121 and a third side panel 122 connected to the two ends of the first side panel 11. Similarly, the shapes of the first side panel 11, the second side panel 121 and the third side panel 122 are not limited, and the two ends of the reinforcing rib 2 are connected to the second side panel 121 and the third side panel 122.

[0045] In a third embodiment, the side panel assembly 12 further includes a fourth side panel (not shown), the second side panel 121 and the third side panel 122 are disposed opposite each other, the first side panel 11 and the fourth side panel are disposed opposite each other, and the ends of the reinforcing rib 2 are connected to the second side panel 121 and the third side panel 122. Similarly, the shapes of the four side panels are not limited. Furthermore, the four side panels are all flat panels, and the first side panel 11, the second side panel 121, the third side panel 122, and the fourth side panel are connected to form a channel 1A having a rectangular cross-section.

[0046] According to the structural strength requirements of the channel 1A, reinforcing ribs 2 may also be provided on the side panel assembly 12 , without limitation.

[0047] In the prior art, the flat iron or bulb flat steel structure installed in the channel 1A is relatively abrupt, which has a significant impact on the water flow. Therefore, in one embodiment, the surface of the protrusion 21 is a smooth transition surface to ensure that the wall structure formed by the first side plate 11 and the reinforcing rib 2 is as smooth as possible, thereby helping to reduce the resistance to water flow and improve the efficiency of water flow. In one embodiment, the protrusion 21 is a hemispherical protrusion, an ellipsoidal protrusion, or a spherical crown protrusion, etc., without limitation. In one embodiment, as Figure 6 As shown, the reinforcing rib 2 is made of round steel. This is an existing structure. When two channels 1A share a common wall through the first side plate 11, the round steel can be directly applied between the two channels 1A, resulting in arc-shaped transitions on both sides, facilitating water flow. The round steel is centered with the mounting plate 111 for easy assembly. To meet the flexure requirements of the wall panel, based on the prior art section modulus of flat iron (specification FB100x10mm), a round steel size of D100, or 100mm in diameter, is calculated to meet the requirements. This shows that, while maintaining the same structural strength, the space occupied by the round steel in channel 1A is much smaller than that occupied by the flat iron.

[0048] In one embodiment, the diameter of the round steel is 100 mm to avoid the round steel being too large, which would affect water flow efficiency, and the round steel being too small, which would affect structural strength. In other embodiments, the round steel diameter can be calculated based on the equivalent module of other flat irons and can be set according to needs without limitation.

[0049] In other embodiments, the reinforcing rib 2 may also be made of elliptical steel, without limitation.

[0050] In one embodiment, if Figure 7 and Figure 8As shown, the ends of the reinforcing ribs 2 are formed into beveled structures 23. The thickness of the ends of the beveled structures 23 is the same as the thickness of the first side panel 11, the second side panel 121, and the third side panel 122, thereby reducing stress concentration after welding the reinforcing ribs 2 to the second and third side panels 121, 122. Furthermore, the beveled structures 23 have an inclination angle of 45°-60°, and can be 45°, 60°, or 50°, etc., without limitation. Furthermore, the beveled structures 23 are symmetrically arranged on both sides of the reinforcing ribs 2, and the two beveled structures 23 are arranged along the width direction of the channel 1A.

[0051] In one embodiment, if Figure 6 and Figure 7 As shown, the reinforcement rib 2 is welded to the wall panel unit 1, and round steel is used as the reinforcement rib 2. The two sides of the round steel are respectively corner-jointed with the mounting plate 111, and the welding is a common corner weld. The height of the weld leg 3 is 0.5 times the thickness of the first side plate 11.

[0052] This embodiment also provides a method for manufacturing the above-mentioned ship transverse passage, comprising:

[0053] S1, the end of the previous mounting plate 111 is welded to the side plate assembly 12;

[0054] S2 and the reinforcing rib 2 are welded to the side of the previous mounting plate 111 and the side plate assembly 12 respectively;

[0055] S3. The end of the rear mounting plate 111 is welded to the side plate assembly 12, and the side of the rear mounting plate 111 is welded to the reinforcing rib 2, so that the front mounting plate 111 and the rear mounting plate 111 are welded to both sides of the reinforcing rib 2.

[0056] The reinforcing ribs 2 and the mounting plate 111 are welded to the side panel assembly 12 in sequence to form a transverse channel for easy assembly.

[0057] When the side panel assembly 12 includes a second side panel 121 and a third side panel 122, the second side panel 121 can be used as the base for reverse manufacturing, with the mounting plate 111 and the reinforcing rib 2 welded to the second side panel 121 in sequence. After the mounting plate 111 and the reinforcing rib 2 form an integral wall panel, the third side panel 122 is welded to the end of the integral wall panel opposite the second side panel 121. Alternatively, the mounting plate 111 can be welded between the second side panel 121 and the third side panel 122, and the reinforcing rib 2 can be welded between the second side panel 121 and the third side panel 122, without limitation.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
