[0002] Ship is a general term for various vessels. Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performance, equipment and structural types according to different usage requirements.

[0003] A ship is a man-made means of transportation that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats, which are collectively called ships or boats. The interior mainly includes accommodating space, supporting structures and drainage structures, and has a propulsion system that utilizes external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly updated with the advancement of science and technology. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly steel, aluminum, fiberglass, acrylic and various composite materials. Due to the diversity of ship types, larger areas of large ships require temporary partitions, and the maintenance areas of small ships have a market demand for coamings. In response to the continuous updating of market requirements, the market demand for coamings has been derived.

[0004] The existing Chinese patent with publication number CN115007989A discloses a ship-use ultra-thin large-size titanium steel metal composite plate and its preparation method, which belongs to the field of metal material technology. The technical problem solved by the present invention is to provide an ultra-thin large-size titanium steel metal composite plate suitable for ship hulls and decks and its preparation method. The ship-use ultra-thin large-size titanium steel metal composite plate of the present invention is prepared by composite titanium plate and steel plate; the thickness of the titanium plate is 0.5mm-2mm, the length of the titanium plate and the steel plate is 8000mm-10000mm, and the thickness of the steel plate is ≥10mm. The present invention realizes the metallurgical bonding of 8000mm-10000mm ultra-thin titanium material and steel plate for the first time, saving a large amount of titanium material and greatly reducing the application cost of titanium plate.

However, in actual ships, application limitations are often encountered, especially when the inspection area is particularly large or scattered. However, in order to ensure the stability, the existing metal composite panels have more inner layer structures and are fixedly installed on the ship. The surface needs to be cut and processed to achieve the inspection hole to achieve the inspection effect, which increases the amount of engineering work, and processing on the ship takes a lot of time. Depending on the processing scenario, many inconveniences are added, and the metal plates commonly used in ships are prone to corrosion and rust, which reduces their service life.

[0018] Furthermore, a flip clamping hole is provided on the top of the flip rod, and the clamping pin is docked and installed with the flip clamping hole.

[0019] Furthermore, a buffer device is provided on the rear side of the metal composite plate flip plate, and the buffer device includes a fixed block, and the fixed blocks are fixedly installed on the upper and lower sides of the rear side of the metal composite plate flip plate, the inner side of the fixed block is fixedly connected with a sliding rod, and the upper and lower sides of the sliding rod surface are slidably connected with sliders, the rear side of the slider is movably connected with a movable rod, the inner side of the slider is movably connected with a hard spring, and the rear side of the movable rod is movably connected with a fixed rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] First, in the present invention, the main board of the metal composite plate includes a composite plate body, and the outer part of the composite plate body is coated with a titanium alloy coating layer. Titanium is a metal with a strong passivation tendency. It can quickly generate a stable oxidizing protective film in the air and in an oxidizing or neutral aqueous solution. Even if the film is damaged for some reason, it can quickly recover automatically. Therefore, titanium has excellent corrosion resistance in oxidizing and neutral media. Therefore, metal composite plates used in ships are generally prone to rust due to long-term use at sea and contact with air with high humidity. Titanium also has corrosion resistance and fatigue stability, which greatly prolongs the service life of metal composite plates. The titanium alloy coating layer is sprayed with an antibacterial topcoat layer on the outside, and the antibacterial topcoat layer is sprayed with an inorganic thermal infrared coating layer on the outside. The antibacterial topcoat layer has antibacterial and antibacterial properties, which can avoid environmental pollution caused by the reproduction of bacteria and molds. The inorganic thermal infrared coating layer adopts an irregular spraying method to spray it on the surface of the metal composite plate in different thicknesses, forming different infrared emissivity of the plate surface, improving the thermal infrared segmentation characteristics, and adding special flaky micron-grade silicon-coated aluminum powder to the thermal infrared inorganic coating to improve the thermal infrared emissivity, effectively preventing infrared detection, and is suitable for ship operations with high confidentiality requirements;

[0022] Secondly, in the present invention, the metal composite plate main board and the metal composite plate flip plate are flipped through the flip rod and the flip auxiliary block, and the clamping pin and the flip clamping hole are docked and installed and clamped and fixed. When the metal composite plate is used, it is spliced, and the metal composite plate flip plate is flipped at the position where the inspection hole needs to be opened to achieve the effect of leaving the inspection hole, and the limit screw that is installed through the through hole at the position of the threaded installation groove to be disassembled to control the flipping activity of the flip rod, so as to achieve the flipping effect at the required flipping position, and ensure the stability of the metal composite plate main board at the position where flipping is not required, so as to increase its convenience in use, and the metal composite plate flip plate at the position where maintenance is required is flipped, so as to avoid on-site hole opening processing on the surface of the metal composite plate, increase the difficulty of processing on the ship, and affect the normal shipping of the ship, and also avoid the processing on the ship to cause wood chips and dust pollution on the ship and some sea areas.

[0023] Thirdly, in the present invention, the metal composite plate flip plate is connected to the metal composite plate main board through multiple groups of limit blocks and limit slots on the outside of the metal composite plate flip plate, and the limit downward limit block portion and the limit upward limit block portion provided at the bottom and top of the limit block are connected to the limit upward limit portion and the limit downward limit portion provided at the bottom and top of the limit slot, respectively. According to the characteristics of the limit downward limit block portion and the limit upward limit block portion, the metal composite plate flip plate and the metal composite plate main board are flipped in only one direction, which ensures that the metal composite plate is flipped in only one direction when in use, avoids the metal composite plate flip plate flipping back and forth to affect the maintenance of the inside of the metal composite plate main board, and reduces the collision between the inside and the outside.

[0024] Fourthly, in the present invention, by installing two groups of longitudinal mounting blocks on the top of the metal composite board main board, longitudinal mounting holes for docking installation are provided on the longitudinal mounting blocks, two groups of longitudinal mounting openings for docking with the longitudinal mounting blocks are provided on the bottom of the metal composite board main board, and longitudinal docking holes for docking with the longitudinal mounting holes are provided on the metal composite board main board at the positions of the longitudinal mounting openings, so that the metal composite board main board is fixedly installed in both the top and bottom directions, thereby ensuring the stability of the metal composite board when used as a whole.

[0025] Fifth, in the present invention, when the fixed plate moves inwardly by the extrusion force, the movable rod flips outward and pushes the slider to move to both sides. At this time, the hard spring is deformed due to the action of the force, and pulls the slider back to the initial position through its own tension. The horizontal extrusion force is converted into vertical pressure through the cooperation of the slider and the movable rod, and the spring is used for buffering, thereby avoiding excessive force when opening and closing the metal composite plate flip plate, and the metal composite plate flip plate directly touches other walls or objects and produces collisions, resulting in scratches on the surface of the metal composite plate flip plate.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following layers will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0039] Reference Figure 1-2 and Fig. 9 As shown, a metal composite plate for a ship comprises a metal composite plate main board 1, wherein the metal composite plate main board 1 comprises a composite plate body A, the composite plate body A is coated with a titanium alloy coating layer B in a circle, the titanium alloy coating layer B is sprayed with an antibacterial topcoat layer C on the outside, and the antibacterial topcoat layer C is sprayed with an inorganic thermal infrared coating layer D on the outside;

[0040] Titanium is a metal with a strong tendency to passivate. It can quickly form a stable oxidizing protective film in the air and in oxidizing or neutral aqueous solutions. Even if the film is damaged for some reason, it can quickly recover automatically. Therefore, titanium has excellent corrosion resistance in oxidizing and neutral media. Due to the great passivation performance of titanium, in many cases, when it comes into contact with dissimilar metals, it does not accelerate corrosion, but may accelerate the corrosion of dissimilar metals. For example, in low-concentration non-oxidizing acids, if Pb, Sn, Cu or monel alloy is in contact with titanium to form a galvanic couple, the corrosion of these materials will accelerate, while titanium will not be affected. In hydrochloric acid, when titanium comes into contact with low-carbon steel, the new hydrogen generated on the titanium surface destroys the titanium oxide film, which not only causes hydrogen embrittlement of titanium, but also accelerates the corrosion of titanium. This may be due to the high activity of titanium to hydrogen. The iron content in titanium affects the corrosion resistance in certain media. In addition to the reasons for the increase in iron, the reason is often that the contaminated iron penetrates into the weld during welding, which increases the local iron content in the weld. At this time, the corrosion has an uneven nature. When using iron parts to support titanium equipment, iron contamination on the iron-titanium contact surface is almost inevitable. Corrosion is accelerated in the iron contaminated area, especially in the presence of hydrogen. When the titanium oxide film on the contaminated surface is mechanically damaged, hydrogen penetrates into the metal. Depending on the temperature, pressure and other conditions, hydrogen diffuses accordingly, which causes titanium to produce varying degrees of hydrogen embrittlement. Therefore, titanium should be used to avoid surface iron contamination in medium temperature, medium pressure and hydrogen-containing systems. Under normal circumstances, titanium will not suffer from pitting corrosion. Titanium also has anti-corrosion fatigue stability. The titanium alloy coating layer B is sprayed with an antibacterial topcoat layer C on the outside, and the antibacterial topcoat layer C is sprayed with an inorganic thermal infrared coating layer D on the outside. The antibacterial topcoat layer C has antibacterial and antibacterial properties, which can avoid environmental pollution caused by the growth of bacteria and molds. The inorganic thermal infrared coating layer D adopts an irregular spraying method to spray it on the surface of the metal composite plate in different thicknesses, forming different infrared emissivity of the plate surface, improving the thermal infrared segmentation characteristics, and adding special flaky micron-level silicon-coated aluminum powder to the thermal infrared inorganic coating to improve the thermal infrared emissivity, effectively preventing infrared detection, and is suitable for ship operations with high confidentiality requirements;

[0043] Reference Figure 3 , 6 -8, the metal composite plate flip plate 2 is snap-fitted and installed on the metal composite plate main board 1, and is used for flipping so that the metal composite plate main board 1 flips out an opening. The metal composite plate flip plate 2 includes a plurality of groups of limit blocks 23 and a limit slot 22 on the outer circle, an auxiliary bottom plate 24 installed on the metal composite plate flip plate 2, and a flip rod 21 for flipping that runs through one side of the metal composite plate flip plate 2.

[0044] The limit block 16 is arranged between the metal composite plate flip plate 2 and the docking plate 14, and is used to install the flipping of the metal composite plate flip plate 2. Through holes are penetrated at the top and bottom of the limit block 16.

The pressing block 4 includes a flip auxiliary block 41 installed at the bottom, a clamping pin 42 installed at the bottom of the flip auxiliary block 41, and a flip clamping hole 211 is opened on the top of the flip rod 21. The clamping pin 42 is docked and installed with the flip clamping hole 211; in order to meet the needs of market development, the cabin metal composite plate has always been installed in a fixed manner, or an opening is cut on the fixed metal composite plate as an inspection hole, and then an inspection door is made and installed to be used in the inspection area. However, in actual ships, it is often encountered with limitations in use, especially when the maintenance area is particularly large or particularly scattered. However, in order to ensure the stability effect, the existing metal composite plate has more inner layer structures and is fixedly installed on the ship. It is necessary to cut and process its surface to achieve the maintenance effect of the maintenance hole, which increases the amount of engineering work, and it takes a lot of time to process on the ship. In addition, depending on the processing scene, many inconveniences are added.

When the metal composite plate is used, it is spliced, and the metal is fixed at the position where the maintenance hole needs to be opened. The composite plate flip plate 2 is flipped to achieve the effect of leaving an inspection port, and a limit screw that is installed through the through port 17 at the position of the threaded mounting groove 18 to jam the flip rod 21 is disassembled to control the flipping activity of the flip rod 21, thereby achieving a flipping effect at the required flipping position, and ensuring the stability of the metal composite plate main board 1 at the position where flipping is not required, thereby increasing its convenience in use, and the metal composite plate flip plate 2 at the position where maintenance is required is flipped, avoiding on-site hole opening processing on the surface of the metal composite plate, increasing the difficulty of processing on the ship, and affecting the normal shipping of the ship, while also avoiding processing on the ship. The pollution caused by wood chips and dust on the ship and some sea areas is also avoided.

[0046] Reference Fig.10As shown, a buffer device 5 is provided at the rear side of the metal composite plate flip plate 2, and the buffer device 5 includes a fixed block 501, and the fixed blocks 501 are fixedly installed on the upper and lower sides of the rear side of the metal composite plate flip plate 2, and the inner side of the fixed block 501 is fixedly connected with a slide bar 502, and the upper and lower sides of the surface of the slide bar 502 are slidably connected with a slider 503, and the rear side of the slider 503 is movably connected with a movable rod 504, and the inner side of the slider 503 is movably connected with a hard spring 505, and the rear side of the movable rod 504 is movably connected with a fixed rod 506, and the fixed plate 506 is pressed inward by the fixed plate 506.

The horizontal extrusion force is converted into vertical pressure through the cooperation of the slider 503 and the movable rod 504, and the spring is used for buffering, thereby avoiding excessive force when opening and closing the metal composite plate flip plate 2, and the metal composite plate flip plate 2 directly touches other walls or objects and produces collisions, so that scratches appear on the surface of the metal composite plate flip plate 2.

When the metal composite panels for ships are in use, an opening needs to be cut on the fixed metal composite panels as an inspection hole for the inspection area. The longitudinal mounting block 31 on the top of the metal composite panel main board 1 is docked with the longitudinal mounting opening 33 at the bottom of the metal composite panel main board 1, and the longitudinal docking hole 34 is fixedly installed with the longitudinal mounting hole 32 by screws, and the two sides of the metal composite panel main board 1 are clamped at the docking groove 13, and the docking hole 11 is installed through the fixing bolts. For fixed installation, at the position where a hole needs to be opened, a limit screw that is installed at the position of the threaded installation groove 18 and that is stuck with the flip rod 21 is disassembled so that it controls the flipping activity of the flip rod 21, thereby achieving a flipping effect at the required flipping position, and ensuring the stability of the metal composite board main board 1 at the position where flipping is not required. At the position where flipping is required, a limit screw that is installed at the position of the threaded installation groove 18 and that is stuck with the flip rod 21 is spirally disassembled from the metal composite board main board 1 through the through-hole 17 and the threaded installation groove 18, and the flip auxiliary block 41 and the flip rod 21 cooperate to drive the metal composite board flip plate 2 to flip to reach the opening at this position.
