Description

Technical Field

[0001] This invention mainly relates to the technical field of shipbuilding engineering, specifically a modular structure for cruise ship cabins. Background Technology

[0002] Currently, the construction cycle of luxury cruise ships is generally quite long. This involves a large number of cabin units, and their installation typically requires the completion of the hull structure, outfitting, airtightness, and insulation works before the cabin construction phase can begin. This type of work is mostly concentrated in the dock or marina stage, significantly extending the overall construction cycle and impacting project delivery schedules. Furthermore, the complex and variable construction environment on board places higher demands on the construction quality and process management of cabin units, making on-site operations challenging and quality control difficult to guarantee.

[0003] Although some luxury cruise ships have adopted modular prefabrication technology for cabins, existing technologies still suffer from problems such as complex connection structures, low on-site assembly efficiency, and insufficient sealing and structural stability. Most prefabricated units require perforation or welding of the rods during connection, affecting structural integrity and hindering rapid disassembly and maintenance. Therefore, there is an urgent need to develop a modular cruise cabin structure that is structurally sound, easy to install, reliably connected, and possesses good sealing performance. This would enable rapid prefabrication, efficient assembly, and overall hoisting of cabin units, significantly shortening the construction cycle, reducing labor and material costs, and improving construction quality. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. Specifically, the present invention mainly provides a modular structure for cruise ship cabins to solve the technical problems mentioned in the background.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A modular structure for cruise ship cabins includes a cabin unit body and a protective structure disposed outside the cabin unit body. The protective structure includes a top plate, a bottom plate, and several side plates. Each plate is connected to an integral connecting rod, and several connecting rods are connected together by a connecting structure. The connection structure includes a base, three locking units, and three pins fixed to the three sides of the base respectively. The end of the connecting rod is provided with an inner protrusion. The pins are inserted into the end of the connecting rod, and the locking units push the inner protrusion against the side wall of the base from the connecting rod. The end of the connecting rod is fixed with four inner protrusions, which are located in the middle of the four inner walls of the connecting rod. The inner protrusions are provided with limiting holes that extend through the length of the connecting rod. The pin includes four support posts, which correspond to the four inner wall edges of the connecting rod. The support posts are misaligned with the inner protrusions. When the pin is inserted into the end of the connecting rod, the inner protrusions are located between two adjacent support posts.

[0006] Preferably, the locking unit includes: A locking rod is provided, and the base has a through hole for the locking rod to pass through; The slide has a threaded hole that mates with the locking rod, and four push blocks, each corresponding to one of the four support columns, are fixed on the slide. The push block is equipped with two clamping mechanisms. When the slide moves toward the pin, the clamping mechanism abuts against the inner protrusion.

[0007] Preferably, the clamping mechanism includes: The clamping block has a first guide slope at one end near the support column; A support block is fixed to the other side of the abutment block. The end of the support block away from the abutment block is provided with a second guide slope, and the support block is slidably mounted on the push block. The support column is provided with a third guide slope that cooperates with the first guide slope at one end near the push block, and the push block is provided with a fourth guide slope that cooperates with the second guide slope. When the slide moves toward the pin, causing the third guide slope to abut against the first guide slope and the fourth guide slope to abut against the second guide slope, the abutting block and the support block move toward the adjacent push block, thereby causing the abutting block to abut against the inner protrusion.

[0008] Preferably, the push block has a groove parallel to the fourth guide slope, the support block has a slider that is slidably installed in the groove, and the push block has a push wall that cooperates with the end of the support block. When the second guide slope slides to the end of the fourth guide slope, the end of the support block abuts against the push wall.

[0009] Preferably, the clamping blocks of the two corresponding clamping mechanisms on the two adjacent push blocks cooperate to abut the inner protrusion and form support for the two adjacent support columns.

[0010] Preferably, a limiting pin is fixed on the abutting block, a receiving groove for accommodating the limiting pin is provided on the support column, and a blind hole that cooperates with the limiting pin is provided on the base; when the abutting block abuts against the inner protrusion, the limiting pin passes through the limiting hole and is inserted into the blind hole.

[0011] Preferably, a hexagonal head is fixed at one end of the locking rod inside the base, and a sealing ring is fitted on the locking rod between the hexagonal head and the side wall of the base.

[0012] Preferably, a sealing gasket is provided between the base and the connecting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By setting up modular connecting rods and multi-directional connection structures, this invention enables rapid positioning and assembly of cabin units, significantly improving the construction efficiency and quality of cruise ship cabins. The connection structure adopts an internal locking mechanism, eliminating the need for perforation or welding on the outer wall of the connecting rod, thus maintaining the integrity and aesthetics of the rod structure, while also possessing excellent sealing and corrosion resistance.

[0014] (2) The connection structure designed in this invention includes a base, a pin, and a locking unit. The pin is inserted into the connecting rod body, and the locking unit abuts against the inner protrusion from the inside to form a stable three-dimensional connection node. This structure not only enables quick assembly and disassembly, but also ensures high rigidity and anti-loosening ability at the connection through multi-sloping guides and limiting pins, making it suitable for ship vibration environments.

[0015] (3) The clamping mechanism in the locking unit can simultaneously provide auxiliary support to the support column during the locking process, further enhancing the overall load-bearing capacity of the structure. The cooperation between the limiting pin and the blind hole further constrains the displacement of the inner protrusion, forming multiple locking mechanisms and improving the reliability of the connection.

[0016] (4) By setting a sealing ring and a sealing gasket, the present invention effectively prevents external moisture and humidity from entering the interior of the connection structure, avoids corrosion of metal parts, extends service life, and is particularly suitable for high humidity and high salt environment at sea.

[0017] (5) This structure supports the prefabrication and partial outfitting of the cabin unit on land, and then the whole unit is transported to the ship for hoisting and positioning, which greatly reduces the time and complexity of the ship's operation, improves construction safety, and is conducive to quality control and standardized production.

[0018] (6) This modular structure has good versatility and scalability, and can adapt to the layout requirements of different cruise ship cabins, promoting the development of cruise ship construction towards modularization, standardization and industrialization.

[0022] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intermediate element present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intermediate element present. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Example 1: Please refer to the appendix carefully. Figure 1 As shown, a modular structure for a cruise ship cabin includes a cabin unit body 3 and a protective structure 4 disposed outside the cabin unit body. The protective structure 4 includes a top plate, a bottom plate, and several side plates. Each plate is connected to an integral connecting rod 1, and several connecting rods 1 are connected by a connecting structure.

[0026] After the main body of the compartment unit 3 is completed, the prefabricated main body of the compartment unit 3 is first transported to the vicinity of the dock by flatbed truck. Then, the main body of the compartment unit 3 is transported to the required deck by the temporary compartment transport elevator on the ship. Then, the main body of the compartment unit 3 is lifted by ~30mm by tooling and transported to the corresponding area, realizing the assembly of the compartment on the ship and below the ship. Then, the whole thing is transported onto the ship, which greatly reduces the difficulty and workload of compartment construction and effectively ensures the quality of compartment construction and the cycle of ship construction.

[0027] Example 2: Based on Example 1, please refer to the appendix for details. Figure 1-10 As shown, the connection structure includes a base 21, three locking units 22, and three pins 23 respectively fixed to three sides of the base 21. The base 21 has clearance grooves on its three sides facing away from the pins 23 to facilitate adjustment of the locking units 22.

[0028] Each pin 23 includes four support posts 231, which correspond to the four inner wall edges of the connecting rod 1, respectively. The support posts 231 are offset from the inner protrusions 11. When the pin 23 is inserted into the end of the connecting rod 1, the support posts 231 and the inner protrusions 11 do not interfere with each other. Simultaneously, each inner protrusion 11 is located between two adjacent support posts 231. The three locking units 22 are also initially offset from the inner protrusions 11, allowing the locking units 22 to be inserted into the connecting rod 1.

[0029] The locking unit 22 includes a locking rod 221 and a slide 222. The slide 222 has a through threaded hole 2221, and the locking rod 221 has a thread that mates with the threaded hole 2221. One end of the locking rod 221 is fixed with a hexagonal head 2211, and the base 21 has a through hole 211 that mates with the locking rod 221. The locking rod 221 can pass through the through hole 211, and the slide 222 is sleeved on the locking rod 221. In the initial state, the slide 222 is located on the side of the support column 231 away from the base 21, and the hexagonal head 2211 is located on the side of the base 21 away from the support column 231. When the hexagonal head 2211 is rotated, the locking rod 221 rotates and drives the slide 222 to move towards the base 21 within the connecting rod body 1.

[0030] Four push blocks 2222 are fixed on the slide block 222, each corresponding to one of the four support columns 231. These push blocks 2222 are also offset from the inner protrusion 11. Figure 3 As shown, the four push blocks 2222 and the slide block 222 are misaligned with the inner protrusion 11 to facilitate insertion into the connecting rod body 1. Figure 10 As shown, each push block 2222 is equipped with two clamping mechanisms, which are located on two sides of the push block 2222. The inner wall of one side of the connecting rod 1 corresponds to two clamping mechanisms located on the two push blocks 2222 respectively. When the slide 222 moves towards the base 21, the clamping mechanism cooperates with the support column 231, gradually offsetting the support column 231 and abutting against the inner protrusion 11, thereby fixing the connecting rod 1 to the base 21.

[0031] The clamping mechanism specifically includes a clamping block 223, a support block 224, and a mounting groove formed on the push block 2222. Two sliding grooves 226 are formed on the bottom of the mounting groove. Two sliders are fixed to the bottom of the support block 224 and slidably installed in the sliding grooves 226, thus allowing the support block 224 to slide within the mounting groove. The clamping block 223 is fixed to one side of the support block 224 and extends beyond the mounting groove. A first guide slope 2231 is formed at the end of the clamping block 223 near the support column 231, and a second guide slope 2241 is formed at the end of the support block 224 away from the clamping block 223. A fourth guide slope 225, which mates with the second guide slope 2241, is formed on the wall of the mounting groove. A third guide slope 2311, which mates with the first guide slope 2231, is formed at the end of the support column 231 away from the base 21. The fourth guide slope 225 is parallel to the sliding grooves 226. The mounting groove is also provided with a push wall 227 that connects with the fourth guide slope 225. The push wall 227 is used to cooperate with the end of the support block 224.

[0032] In the initial state, the first guide slope 2231 of the clamping block 223 abuts against the third guide slope 2311 of the support column 231, and the second guide slope 2241 of the support block 224 abuts against the fourth guide slope 225 on the push block 2222. As the slide block 222 gradually moves towards the base 21, the third guide slope 2311 and the fourth guide slope 225 respectively push the first guide slope 2231 and the second guide slope 2241, causing the support block 224 to move along the slide groove 226. This causes the clamping block 223 to gradually shift away from the support column 231 and move towards the adjacent push block 2222 until the second guide slope 2241 slides to the end of the fourth guide slope 225. At this point, the end of the support block 224 abuts against the push wall 227, while the clamping block 223 is completely shifted away from the support column 231, and one side wall of the clamping block 223 adheres to one side wall of the support column 231. Two adjacent abutting blocks 223 on two adjacent push blocks 2222 will abut together and face the inner protrusion 11. When the slide block 222 moves further, the two abutting blocks 223 will eventually abut against the inner protrusion 11, and the two abutting blocks 223 will support the two adjacent support columns 231, so that the four support columns 231 and the eight abutting blocks 223 form a rectangular frame structure, further enhancing the structural strength of the pin 23. At the same time, the abutting blocks 223 can push the support columns 231 against the inner wall of the connecting rod 1, so that the support columns 231 and the inner wall of the connecting rod 1 are interference-fitted, further enhancing the connection strength.

[0033] When using, such as Figure 4 As shown, the locking unit 22 can be installed on the base 21 first, so that the slide 222 is away from the support column 231. Then, the connecting rod 1 is fitted onto the slide 222 and the support column 231. After that, the hexagonal head 2211 is rotated so that the base 21 moves towards the support column 231 inside the connecting rod 1. Finally, the abutment block 223 abuts against the inner protrusion 11 and the side wall of the support column 231, so as to achieve a stable connection between the base 21 and the connecting rod 1 and complete the assembly of the cabin unit.

[0034] Example 3: Based on Example 2, please refer to the appendix for details. Figure 1-10 As shown, a limiting pin 228 is fixed on the abutment block 223. A receiving groove 2312 for accommodating the limiting pin 228 is provided on the side of the support column 231.

[0035] The base 21 has a blind hole 212 that mates with the limiting pin 228. When the abutting block 223 abuts against the inner protrusion 11, two adjacent limiting pins 228 located on the two push blocks 2222 respectively pass through the limiting hole 111 on the inner protrusion 11 and are inserted into the same blind hole 212. Figure 7When viewed from the reference position, the clamping block 223 and the base 21 cooperate to form a lateral limit on the inner protrusion 11, while the limiting pin 228 forms a longitudinal limit on the inner protrusion 11, further enhancing the connection strength between the connecting rod body 1 and the corner connecting seat. At the same time, a protrusion 22221 is provided at the end of the push block 2222 near the support column 231, and an inner groove 2313 is provided on the support column 231. When the clamping block 223 abuts against the inner protrusion 11, the protrusion 22221 can be inserted into the inner groove 2313, enhancing the connection between the push block 2222 and the support column 231.

[0036] Example 4: Based on Example 3, please refer to the appendix for details. Figure 1-10 As shown, a sealing ring 2212 is fitted onto the locking rod 221 between the hexagonal head 2211 and the side wall of the base 21. The sealing ring 2212 prevents external moisture from entering the connecting rod body 1 through the through hole 211 of the base 21. A sealing gasket 213 is also provided between the base 21 and the connecting rod body 1, covering the four support columns 231 to prevent external moisture from entering the connecting body 1 through the connection between the connecting rod body 1 and the base 21. With the above settings, rainwater and moisture can be effectively prevented from entering the interior of the connecting rod body 1, protecting components such as the locking rod 221 and support columns 231, preventing internal corrosion, and extending the service life of the cabin unitization.
