Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine engineering materials technology, specifically to a high-strength outfitting plate that can withstand extreme marine environments. Background Technology
[0002] Outfitting plates are crucial in shipbuilding. They are used for outfitting operations such as interior decoration and equipment installation. In extreme marine environments, whether facing long-term corrosion from high-salinity seawater or the impact and vibration caused by strong winds and waves, these high-strength outfitting plates exhibit excellent resistance. Their surface undergoes special protective treatment to form a dense and strong anti-corrosion coating, which effectively blocks seawater erosion, ensures long-term structural stability, and provides a solid guarantee for the normal operation and long service life of the ship.
[0003] Application No. 202321172386.5 discloses a foamed aluminum outfitting panel, "including a shell, grooves on both sides of the shell, buttons installed in the grooves, a slot at the top of the shell, an outfitting panel inside the slot, movable grooves on both sides of the outfitting panel, a first spring on one side of the movable groove, a limiting plate on one side of the first spring, and a rectangular clamping plate on one side of the limiting plate." While the above uses buttons, grooves, movable grooves, a first spring, a limiting plate, and a rectangular clamping plate to a certain extent to achieve the function of installing and fixing the outfitting panel, the above-mentioned design utilizes buttons, grooves, movable grooves, a first spring, a limiting plate, and a rectangular clamping plate to achieve the function of installing and fixing the outfitting panel to a certain extent. Yes, it is possible. However, outfitting plates are generally composed of a face plate, a core layer, and a back plate. When faced with seawater erosion and micro-damage caused by complex stress, they lack an active repair mechanism. Once a small crack or damage occurs, it is difficult to deal with it in time. In the harsh marine environment, seawater continues to erode and complex stresses are repeatedly applied. These micro-damages cannot be repaired and continue to accumulate, causing a serious decline in the reliability and durability of the outfitting plates. After long-term use, the continuous accumulation of potential damage is very likely to pose a safety hazard to ship navigation and threaten the safe operation of the ship. Utility Model Content
[0004] The purpose of this invention is to provide a high-strength outfitting plate that can withstand extreme marine environments, in order to overcome the aforementioned shortcomings in the technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength outfitting plate resistant to extreme marine environments, comprising a plate body, the plate body comprising a front panel, a core layer, and a back panel arranged sequentially from the outside to the inside, wherein a foam layer is provided in the pre-reserved cavity inside the core layer, which can significantly improve the bending stiffness and impact resistance of the outfitting plate without significantly increasing the weight, while also providing certain heat insulation and sound insulation effects, which helps to improve the working and living environment inside the ship. The outer walls of the back panel and the front panel are provided with an anti-corrosion coating, which can form a dense protective film on the surface of the outfitting plate to prevent seawater, salt spray, etc. from corroding the metal materials. Inserts are fixedly connected to the outer wall of the plate body, and slots are opened on the outer wall of the plate body opposite to the position of the inserts. The slots match the inserts, and the assembly of each outfitting plate can be realized through the cooperation of the slots and the inserts.
[0006] Preferably, shape memory alloy sheets are provided on both outer sides of the foam layer.
[0007] Specifically, when the outfitting plate deforms due to external impact, the built-in shape memory alloy sheet can accurately restore its original shape by virtue of its memory properties. This not only provides an immediate repair effect on the deformed outfitting plate but also simultaneously strengthens the outfitting plate structure, effectively improving its overall strength. At the same time, the shape memory alloy sheet can also generate additional stress as needed through convenient methods such as thermal activation, which can flexibly and accurately adjust the stress state of the outfitting plate under complex working conditions. This greatly enhances the outfitting plate's ability to resist deformation, enabling it to maintain a stable and reliable working state even when facing harsh environments such as strong winds and giant waves. This comprehensively ensures the safe navigation and efficient operation of the ship, safeguarding the ship throughout its entire life cycle.
[0008] Preferably, the plate body has a repair structure inside, the repair structure includes two substrate layers symmetrically arranged outside the core layer, the two substrate layers are equidistantly and uniformly embedded with a plurality of microcapsules, and the two substrate layers are respectively provided with a catalyst layer on the side away from the core layer, the substrate layers being located on the side of the shape memory alloy sheet away from the core layer.
[0009] Through the above technical solution:
[0010] When outfitting plates develop microcracks or damage due to complex stresses and seawater erosion in extreme marine environments, the microcapsules pre-distributed evenly within the substrate layer rupture, releasing a repair agent. This repair agent rapidly contacts the catalyst layer on the surface of the substrate layer, where it quickly undergoes a polymerization and curing reaction, precisely filling the cracks, preventing their expansion, and stabilizing the outfitting plate structure. This self-healing property enhances the reliability and durability of the outfitting plates under harsh conditions, significantly reduces maintenance costs, eliminates safety hazards, and ensures stable performance of the outfitting plates throughout the ship's service life, providing a guarantee for safe navigation.
[0011] Preferably, the insertion block is provided with a locking component, the locking component including a fixed block fixedly connected to the outer wall of the insertion block, a movable block connected to the lower end of the fixed block by a spring, a connecting block movably connected to the movable block, and a locking block fixedly connected to the lower end face of the movable block.
[0012] Preferably, one end of the connecting block is fixedly connected to the insert block, a spring piece is connected in a groove opened on the outer wall of the fixed block, and a short block that cooperates with the spring piece is fixedly connected to the outer wall of the movable block.
[0013] Preferably, the slot is provided with a connecting component for use with the locking component. The connecting component includes a groove formed on the outside of the slot and located on the inner wall of the plate body. A horizontal bar is fixedly connected inside the groove. The upper end face of the horizontal bar is provided with a slot that matches the locking block.
[0014] Through the above technical solution:
[0015] During the assembly of outfitting plates, as the insert block is inserted into the slot, the spring force causes the movable block to change from a horizontal to an inclined state. Simultaneously, the short block moves along the side wall of the spring piece. After insertion, the locking block engages with the slot opened in the horizontal block. This operation ensures reliable locking of the outfitting plates after insertion, effectively preventing accidental detachment of the insert block from the slot, improving the stability and robustness of the assembled outfitting plates. In complex conditions such as vibration and swaying during ship navigation, it ensures that each outfitting plate is tightly connected, maintaining the integrity of the overall structure, significantly reducing safety risks and maintenance costs caused by loose connections, eliminating structural displacement and component wear, avoiding potential connection failures, and laying a solid foundation for the safe and stable operation of ships in extreme marine environments.
[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0017] 1. By setting up a repair structure, when the outfitting plate develops microcracks or damage due to complex stresses and seawater erosion in extreme marine environments, the expansion of the cracks causes the microcapsules, which are pre-distributed evenly inside the substrate layer, to rupture. This releases the repair agent stored in the microcapsules, which can quickly contact the catalyst on the surface of the substrate layer. Under the efficient action of the catalyst, the repair agent rapidly undergoes a polymerization and solidification reaction, precisely filling the crack gaps and achieving perfect crack filling. This timely prevents further crack expansion and continuously stabilizes the structure of the outfitting plate. This self-healing property greatly enhances the reliability and durability of the outfitting plate under harsh marine conditions, significantly reduces maintenance costs, eliminates potential safety hazards, and ensures that the outfitting plate maintains stable and excellent performance throughout the entire service life of the ship, laying a solid foundation for the safe navigation of the ship.
[0018] 2. By setting up locking components, reliable locking can be achieved after the outfitting plates are inserted during the assembly operation. This effectively prevents the plugs from accidentally disengaging from the slots, significantly improving the stability and robustness of the assembled outfitting plates. During daily navigation, when facing complex marine conditions such as vibration and swaying, it can ensure that the outfitting plates always maintain a tight connection, maintaining the integrity of the overall structure. This not only greatly reduces the safety risks and maintenance costs caused by loose connections, but also eliminates adverse phenomena such as structural displacement and component wear, effectively avoiding safety hazards caused by connection failures, and providing a solid guarantee for the safe and stable operation of ships in extreme marine environments.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0030] This utility model provides, for example Figures 1-3 The high-strength outfitting panel shown is resistant to extreme marine environments and includes:
[0031] The plate body 1 includes a front panel 12, a core layer 11, and a back panel 13 arranged sequentially from the outside to the inside. The core layer 11 has a pre-reserved cavity with a foam layer 14, which can significantly improve the bending stiffness and impact resistance of the outfitting plate without significantly increasing the weight. At the same time, it can also provide a certain degree of heat insulation and sound insulation, which helps to improve the working and living environment inside the ship. The outer walls of the back panel 13 and the front panel 12 are provided with an anti-corrosion coating 15, which can form a dense protective film on the surface of the outfitting plate to prevent seawater, salt spray, etc. from corroding the metal materials. The outer wall of the plate body 1 is fixedly connected with a plug 2, and the outer wall of the plate body 1 and the plug 2 are provided with a slot 3 opposite to the position of the plug 2. The slot 3 matches the plug 2. Through the cooperation of the slot 3 and the plug 2, the outfitting plates can be assembled.
[0032] Further, see Figure 2 As shown, shape memory alloy sheets 4 are provided on both sides of the outer surface of the foam layer 14.
[0033] Specifically, when the outfitting plate is deformed by external impact, the built-in shape memory alloy sheet 4 can accurately restore its original shape by virtue of its memory characteristics. This not only has an immediate repair effect on the deformed outfitting plate, but also simultaneously strengthens the outfitting plate structure, effectively improving its overall strength. At the same time, the shape memory alloy sheet 4 can also generate additional stress as needed through convenient methods such as thermal activation. This allows for flexible and precise adjustment of the stress state of the outfitting plate under complex working conditions, greatly enhancing the outfitting plate's ability to resist deformation. This enables it to maintain a stable and reliable working state even when facing harsh environments such as strong winds and giant waves, comprehensively ensuring the safe navigation and efficient operation of the ship, and safeguarding the ship throughout its entire life cycle.
[0034] This utility model provides, for example Figure 2 and Figure 3 The high-strength outfitting plate shown has a repair structure inside the plate body 1. The repair structure includes two substrate layers 5 symmetrically arranged on the outside of the core layer 11. Multiple microcapsules 6 are equidistantly and uniformly embedded in the interior of the two substrate layers 5. Catalyst layers 7 are provided on the side of the two substrate layers 5 away from the core layer 11. The substrate layers 5 are located on the side of the shape memory alloy sheet 4 away from the core layer 11.
[0035] Through the above technical solution:
[0036] When outfitting plates develop microcracks or damage due to complex stresses and seawater erosion in extreme marine environments, the microcapsules 6 pre-distributed evenly within the substrate layer 5 rupture, releasing a repair agent. The repair agent quickly contacts the catalyst layer 7 on the surface of the substrate layer 5, where it rapidly undergoes a polymerization and curing reaction, precisely filling the cracks, preventing their expansion, and stabilizing the outfitting plate structure. This self-healing property enhances the reliability and durability of the outfitting plates under harsh conditions, significantly reduces maintenance costs, eliminates safety hazards, and ensures stable performance of the outfitting plates throughout the ship's service life, providing a guarantee for safe navigation.
[0037] This utility model provides, for example Figure 1 , Figures 4-7 The high-strength outfitting plate shown is resistant to extreme marine environments. The insert 2 is provided with a locking component 8. The locking component 8 includes a fixing block 81 fixedly connected to the outer wall of the insert 2. The lower end of the fixing block 81 is connected to a movable block 82 by a spring. A connecting block 83 is movably connected to the movable block 82, and a locking block 84 is fixedly connected to the lower end face of the movable block 82.
[0038] One end of the connecting block 83 is fixedly connected to the insert block 2. A spring piece 85 is connected in the groove opened on the outer wall of the fixed block 81. A short block 86 that works with the spring piece 85 is fixedly connected to the outer wall of the movable block 82.
[0039] The slot 3 is equipped with a connecting component 9 that works with the locking component 8. The connecting component 9 includes a groove 91 that is opened on the outside of the slot 3 and located on the inner wall of the plate body 1. A horizontal bar block 92 is fixedly connected inside the groove 91. The upper end face of the horizontal bar block 92 is provided with a slot 93 that is adapted to the card block 84.
[0040] Through the above technical solution:
[0041] During the assembly of outfitting plates, as the insert 2 is inserted into the slot 3, the spring force causes the movable block 82 to change from a horizontal state to an inclined state. At the same time, the short block 86 moves on the side wall of the spring piece 85. After being inserted into place, the locking block 84 is engaged in the slot 93 opened in the horizontal block 92. This operation can reliably lock the outfitting plates after they are inserted, effectively preventing the insert 2 from accidentally disengaging from the slot 3, improving the stability and firmness of the outfitting plates after assembly. In complex working conditions such as vibration and swaying during ship navigation, it can ensure that each outfitting plate is tightly connected, maintain the integrity of the overall structure, significantly reduce the safety risks and maintenance costs caused by loose connections, eliminate structural displacement and component wear, avoid the hidden danger of connection failure, and lay a solid foundation for the safe and stable operation of the ship in extreme marine environments.
[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
