Description

Technical Field

[0001] This utility model relates to the field of water platform technology, specifically to a composite material pontoon and a multifunctional floating structure. Background Technology

[0002] Currently, most floating platforms (floating valves) are built using pontoons. In existing technologies, pontoons are mostly made of synthetic foam, HDPE, and other materials, offering versatility and flexibility, and can meet basic aquaculture and operational needs in calm waters such as lakes, shallow seas, and ponds. However, in deep-sea or open-ocean environments, the intrinsic properties of these synthetic foam or HDPE pontoons (low modulus, low strength) are incompatible with the extreme marine environment (typhoons, high currents, corrosion). HDPE's strength is only 1 / 10 that of steel, and its low bending stiffness makes it prone to deformation under dynamic loads. This not only leads to large undulations and swaying of the pontoon platform when personnel walk or equipment operates, resulting in a lack of safety, but also makes it susceptible to fatigue fracture under long-term wave impact. Furthermore, it exhibits poor resistance to currents in high-velocity bays and weak typhoon resistance. These shortcomings limit the application of foam or HDPE pontoons in marine aquaculture and offshore platform construction.

[0003] Therefore, please refer to Chinese Utility Model Patent Application Publication No. CN103895829A, which discloses a continuous pontoon composite material floating structure system. The pontoons are made of fiber-reinforced resin-based composite materials, which, compared to synthetic foam and HDPE, have higher bending and deformation resistance, and can withstand the impact of typhoons and waves. However, because the main structure of the pontoons is cylindrical, even though the pontoon connecting units are equipped with pontoon connecting units for installing the bridge deck structure system, and the top surface of the pontoon connecting units is designed as a plane, the top surface area of ​​the pontoon connecting units is very small, and the number of pontoon connecting units is also limited. Therefore, for the entire floating structure system, the installation support area of ​​the bridge deck structure system is still very limited, resulting in poor load-bearing capacity of the bridge deck structure system, which restricts its application and promotion. Utility Model Content

[0004] In view of this, the present invention provides a composite material pontoon and a multifunctional floating structure.

[0005] The technical solution is as follows:

[0006] The first aspect of this application relates to a composite material pontoon, comprising a pontoon body formed of fiber-reinforced material, the pontoon body being a cylindrical structure extending in a horizontal direction, the interior of the cylindrical body forming a pontoon cavity with a sealed chamber structure, the top of the pontoon body forming a planar mounting plane, the mounting plane extending along the length direction to both ends of the pontoon body, and the mounting plane protruding on both sides along the width direction of the pontoon body to form mounting flanges.

[0007] The use of the above composite material pontoons, with the entire top surface of the pontoon body being a planar installation surface, not only facilitates the assembly and connection with the superstructure, but also allows all the installation surfaces and flanges to support the superstructure, thus providing a huge support area for the superstructure. This significantly improves the load-bearing capacity and stability of the superstructure, thereby greatly increasing the application scenarios and enhancing its versatility.

[0008] The second aspect of this application relates to a multifunctional floating structure, including at least two sets of pipe connection assemblies arranged side by side and at least two of the aforementioned composite material pontoons. Each pontoon body is arranged side by side, and each pipe connection assembly includes at least one connecting support pipe arranged side by side. Each connecting support pipe is vertically arranged on the mounting plane of all pontoon bodies and is locked to all mounting flanges of all pontoon bodies by several sets of pontoon fasteners and pontoon fastener locking elements. Spacing is left between adjacent pipe connection assemblies and between adjacent pontoon bodies, thereby forming multiple operating ports distributed along a planar array.

[0009] The above-mentioned multi-functional floating structure not only possesses all the advantages of the composite material pontoons, but also can be used as various water platforms, with good versatility, high structural strength, and good weather resistance. At the same time, the floating structure can be modularly expanded to have operating ports distributed along a planar array, making it particularly suitable for use in aquaculture.

[0010] The third aspect of this application relates to a multifunctional floating structure, including at least two sets of pipe connection assemblies arranged side by side and at least two of the aforementioned composite material pontoons. Each pontoon body is arranged side by side, and adjacent pontoon bodies abut against each other through the outer edge of the mounting flange. Each pipe connection assembly includes a connecting plate perpendicular to the pontoon body. Each connecting plate is fitted onto the mounting plane of all pontoon bodies and locked to all mounting flanges of all pontoon bodies by a number of connecting plate locking members.

[0011] The above-mentioned multi-functional floating hull structure not only possesses all the advantages of the composite material pontoons, but also can be used as various water platforms, with good versatility, high structural strength, and good weather resistance. At the same time, the top surface of the floating hull structure is relatively flat, which is conducive to the movement of operators. Furthermore, it can be modularly expanded, making it particularly suitable as a water operation platform.

[0012] The fourth aspect of this application relates to a multifunctional floating structure, comprising at least two of the aforementioned composite material pontoons, each pontoon body being arranged side by side, and one mounting flange between adjacent pontoon bodies pressing against another mounting flange, and all being locked together as one unit by a plurality of flange locking members.

[0013] The above-mentioned multi-functional floating hull structure not only possesses all the advantages of the composite material pontoons, but also has a completely flat top surface, which is particularly conducive to the movement of operators. Furthermore, the floating hull structure can be used as various water platforms, with excellent versatility, high structural strength, and good weather resistance. At the same time, the floating hull structure can be modularly expanded, making it particularly suitable as a water operation platform. In addition, apart from the composite material pontoons, only one component, the flange locking component, is needed for the overall assembly, which greatly reduces the difficulty of component management and improves the assembly efficiency of the multi-functional floating hull structure.

[0014] The fifth aspect of this application relates to a multifunctional floating structure, comprising multiple composite material pontoons as described above. Each pontoon body is spliced ​​together by several tee connectors and several four-way connectors to form a grid-like frame structure, thereby collectively constituting multiple operating ports distributed along a planar array.

[0015] The above-mentioned multi-functional floating structure not only possesses all the advantages of the composite material pontoons, but also can be used as various water platforms, with good versatility, high structural strength, and good weather resistance. At the same time, the floating structure can be easily modularized and expanded to form as many operating ports as possible, making it particularly suitable for use in aquaculture.

[0016] The sixth aspect of this application relates to a multifunctional floating pontoon structure, including a top frame and multiple composite material pontoons as described above. The top frame is formed by multiple splicing pipes locked together by several sets of splicing pipe fasteners and splicing pipe fastener locking elements, and spliced ​​to form a grid-like frame structure. The frame structure has multiple operating ports distributed in a planar array. Each pontoon body is staggered from each operating port and arrayed at the bottom of the frame structure. All mounting flanges of all pontoon bodies are locked to at least two corresponding splicing pipes by several sets of pontoon fasteners and pontoon fastener locking elements, so that the mounting plane of each pontoon body abuts against the bottom surface of the corresponding splicing pipe.

[0017] The above-mentioned multi-functional floating structure not only possesses all the advantages of the composite material pontoons, but also can be used as various floating platforms, with good versatility, high structural strength, and good weather resistance. In addition, the floating structure can be expanded to form an ultra-large floating structure, which is particularly suitable as a large-scale aquaculture platform. Attached Figure Description

[0028] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0029] Example 1:

[0030] like Figures 1-3 as well as Figure 5 As shown, a composite material pontoon mainly includes a pontoon body 1, which is formed by fiber-reinforced material. Compared with synthetic foam and HDPE material, composite material has higher bending and deformation resistance and can withstand the impact of typhoons and waves.

[0031] The float body 1 is a cylindrical structure extending in the horizontal direction. Inside the float body 1, a float cavity 1a with a sealed chamber structure is formed. The float cavity 1a is a chamber with excellent airtightness. The float cavity 1a can be filled with air or a lighter inert gas such as helium, so that the float body 1 can serve as an excellent buoyancy-providing device.

[0032] In this embodiment, a planar mounting surface 111 is formed on the top of the float body 1. The mounting surface 111 extends along the length direction to both ends of the float body 1. Mounting flanges 112 are formed on both sides of the mounting surface 111 along the width direction of the float body 1. The two mounting flanges 112 are installed in the following two ways:

[0033] Two installation methods for the flange: 1. Please refer to [link / reference]. Figure 3 The top surfaces of both mounting flanges 112 are flush with the mounting plane 111, meaning that the entire top surface of the pontoon body 1 is a planar structure. This not only facilitates the assembly and connection with the superstructure, but also ensures that all mounting planes 111 and mounting flanges 112 can support the superstructure, thus providing a huge support area for the superstructure. This significantly improves the load-bearing capacity and stability of the superstructure, thereby greatly increasing the application scenarios and enhancing its versatility.

[0034] Installation method 2 for two types of flanged installations: Please refer to [link / reference]. Figure 4 One of the mounting flanges 112 has its top surface flush with the mounting plane 111, while the top surface of the other mounting flange 112 is lower than the mounting plane 111. The height difference between the top surface of the mounting flange 112 lower than the mounting plane 111 and the mounting plane 111 is equal to the thickness of the mounting flange 112 flush with the mounting plane 111. This allows multiple composite material pontoons to be directly assembled into one piece, forming a completely flat platform on their top surface. For details, please refer to Embodiment 4.

[0035] Please see Figures 1-5 Furthermore, the pontoon body 1 includes a cylindrical shell 11 with a cylindrical structure. The mounting plane 111 and the mounting flange 112 are both formed on the top of the cylindrical shell 11. At least one end of the cylindrical shell 11 in the length direction is provided with a mounting opening 113. If both ends of the cylindrical shell 11 in the length direction are provided with mounting openings 113, the structure of the cylindrical shell 11 in the length direction will be completely consistent. This is very beneficial for continuous molding of fiber-reinforced materials through pultrusion process. Not only is the process difficult, but the molding efficiency is also high, which reduces the production cost of the cylindrical shell 11.

[0036] All openings 113 are sealed with plugs 12, which are made of fiber-reinforced material, specifically through a molding process. Compared to synthetic foam and HDPE, this composite material has higher resistance to bending and deformation. At least one sealed inner liner 13 is installed in the float cavity 1a. This allows for easy installation and removal of the sealed inner liner 13 by removing and installing the plugs 12. Furthermore, by adding the sealed inner liner 13, effective buoyancy is still provided even if the shell 11 leaks, providing a double safety measure.

[0037] Similarly, the sealed inner liner 13 can be filled with air or a lighter inert gas such as helium, so that the float body 1 can serve as an excellent buoyancy-providing device.

[0038] The plug 12 includes a plug baffle 121, on the inner side of which a plug 122 is integrally formed to fit the installation opening 113. The plug 122 is embedded in the installation opening 113, thereby achieving a sealing of the installation opening 113.

[0039] Furthermore, the inner side of the plug baffle 121 is integrally formed with an annular outer baffle 123 surrounding the plug 122. An annular fitting gap 124 is formed between the annular outer baffle 123 and the plug 122, which is adapted to the end of the cylindrical shell 11. The ends of the cylindrical shell 11 are respectively embedded in the annular fitting gap 124. That is, the thickness of each position of the end of the cylindrical shell 11 matches the width of each position of the annular fitting gap 124, which can effectively improve the sealing performance of the installation.

[0040] Furthermore, the plugs 122 are all annular thin-walled structures, thereby achieving a lightweight design for the plugs 12 and improving the buoyancy of the pontoon body 1.

[0041] Furthermore, since the plug 12 may need to be disassembled and reassembled frequently, in order to ensure the reliability of the plug 12 installation and the airtightness of the inside of the float body 1, the plug 122 is integrally formed with reinforcing ribs 122a on the inner wall at its corners, which ensures the structural strength of the plug 122 and makes it less prone to deformation.

[0042] In this embodiment, multiple sealed inner liner 13 are preferably installed in the float cavity 1a, so that even if one or more of the sealed inner liner 13 leaks or is damaged, the remaining sealed inner liner 13 can still enable the float body 1 to provide sufficient buoyancy.

[0043] Furthermore, at least the sealed inner liner 13 closest to the installation opening 113 can be detachably installed in the float cavity 1a. This design allows for easy removal of the sealed inner liner 13 closest to the installation opening 113, enabling the float (floating platform) to remain suspended and sink into the sea during extreme weather conditions such as typhoons by partially removing the sealed inner liner 13, thus preventing damage. Once the weather conditions improve, the removed sealed inner liner 13 can be reinstalled, allowing the float (floating platform) to float again on the water.

[0044] Furthermore, the sealing liner 13 is preferably made of PE material through blow molding. Specifically, the blow-molded sealing liner 13 is inflated and fits the cavity within the mold, achieving a seamless welded structure. Compared to spliced ​​liner types, this completely eliminates the risk of leakage at seams, improving sealing performance by over 200%. Simultaneously, the high-density PE molecular chains are dense, resulting in a water vapor permeability as low as 0.1–0.5 g·mm / (m²). 2 (day), far lower than PVC (5–20) g·mm / (m 2 ·day) and rubber (3–15) g·mm / (m 2 It has excellent long-term waterproof stability (day).

[0045] Furthermore, to improve operational convenience, at least the sealed inner liner 13 closest to the installation opening 113 is equipped with an air valve for inflation and deflation. This allows the float (floating platform) to be suspended and sunk into the sea by deflation, preventing damage. Once the weather conditions improve, each deflated sealed inner liner 13 can be inflated, allowing the float (floating platform) to float back to the surface.

[0046] Furthermore, the outer side of the plug baffle 121 forms an outwardly protruding flow guide structure 121a, which is used to guide and transport water when moving in water, and to overcome water flow resistance.

[0047] Example 2:

[0048] Please see Figure 6 A multifunctional floating buoy structure includes at least two sets of pipe connection assemblies 2 arranged side by side and at least two composite material buoys of Embodiment 1. Each buoy body 1 is arranged side by side. Each pipe connection assembly 2 includes at least one connecting support pipe 21 arranged side by side. Each connecting support pipe 21 is vertically arranged on the mounting plane 111 of all buoy bodies 1 and is locked to all mounting flanges 112 of all buoy bodies 1 by several sets of buoy fasteners 22 and buoy fastener locking parts 23, thereby forming a stable and reliable floating buoy structure.

[0049] Specifically, the float fastener 22 is a "U"-shaped fastener, and the float fastener locking part 23 can be a bolt and nut kit or a rivet, so that the float fastener 22 can be locked to the float body 1 in a very convenient and efficient manner.

[0050] Furthermore, the connecting support pipe 21 is continuously formed using a pultrusion process with fiber-reinforced material. This not only reduces the difficulty of the process but also increases the molding efficiency, thereby lowering the production cost of the connecting support pipe 21. The pontoon fastener 22 and the pontoon fastener locking element 23 are preferably formed using fiber-reinforced material, specifically, using a molding process. Compared to synthetic foam and HDPE materials, composite materials have higher bending and deformation resistance. To reduce costs, the pontoon fastener locking element 23 can also be made of stainless steel with good corrosion resistance.

[0051] In this embodiment, there are gaps between adjacent pipe connection components 2 and between adjacent float bodies 1, which together form multiple operation ports 3 distributed along a planar array. Therefore, the operation ports 3 can be modularly expanded, making them particularly suitable for use in aquaculture.

[0052] Furthermore, each of the outermost pipe connection assemblies 2 is equipped with two connecting support pipes 21. The two connecting support pipes 21 of the outermost pipe connection assembly 2 are connected by several pedal connectors (not shown in the figure) to multiple pedals 24 evenly distributed between each adjacent buoy body 1. This facilitates the movement of personnel on the buoy.

[0053] Furthermore, the pedal 24 is made of fiber-reinforced material through a pultrusion process, which not only has low process difficulty but also high molding efficiency, thus reducing the production cost of the pedal 24.

[0054] The pedal connector is preferably fixed with fiber-reinforced cable ties or ropes, which is simple, reliable, and highly corrosion-resistant.

[0055] Example 3:

[0056] Please see Figure 7 A multifunctional floating structure includes at least two sets of pipe connection assemblies 2 arranged side by side and at least two composite material pontoons of Embodiment 1. Each pontoon body 1 is arranged side by side, and adjacent pontoon bodies 1 are abutted by the outer edge of the mounting flange 112. Each pipe connection assembly 2 includes a connecting plate 25 perpendicular to the pontoon body 1. Each connecting plate 25 is fitted on the mounting plane 111 of all pontoon bodies 1, and each connecting plate 25 is locked to all mounting flanges 112 of all pontoon bodies 1 by a number of connecting plate locking members 26.

[0057] The top surface of the multi-functional floating structure in this embodiment is relatively flat, with only the connecting plate 25 slightly protruding, which facilitates the movement of operators on it. At the same time, it can also be modularly expanded, making it particularly suitable as a floating work platform.

[0058] Furthermore, the connecting plate 25 is made of fiber-reinforced material through a pultrusion process, which not only has low process difficulty but also high molding efficiency, thus reducing the production cost of the connecting plate 25.

[0059] The connecting plate locking element 26 can be a bolt and nut kit or a rivet, preferably made of fiber-reinforced material, specifically, using a molding process. Compared to synthetic foam and HDPE, composite materials have higher bending and deformation resistance. To reduce costs, the connecting plate locking element 26 can also be made of stainless steel with good corrosion resistance.

[0060] Example 4:

[0061] Please see Figure 8 A multifunctional floating structure includes at least two composite material pontoons of Embodiment 1, with each pontoon body 1 arranged side by side, and the two mounting flanges 112 are installed in the same way as the two mounting flanges 2 of Embodiment 1.

[0062] Therefore, one mounting flange 112 between adjacent pontoon bodies 1 presses onto another mounting flange 112, and both are locked together as one unit by several flange locking parts 27. The top surface of the multi-functional floating structure in this embodiment is completely flat, which is particularly convenient for operators to move around. At the same time, it can be modularly expanded, making it particularly suitable as a floating operation platform. In addition, apart from the composite material pontoons, the overall assembly only requires one component, the flange locking part 27, which greatly reduces the difficulty of component management and improves the assembly efficiency of the multi-functional floating structure.

[0063] Furthermore, the flange locking component 27 can be a bolt and nut kit or a rivet, preferably molded from a fiber-reinforced material, specifically, manufactured using a molding process. Compared to synthetic foam and HDPE materials, composite materials have higher resistance to bending and deformation. To reduce costs, the flange locking component 27 can also be made of stainless steel with good corrosion resistance.

[0064] Example 5:

[0065] Please see Figure 9 A multifunctional floating structure includes multiple composite material floats of Embodiment 1. Each float body 1 is spliced ​​together by several two-way connectors 7, several three-way connectors 4 and several four-way connectors 5 to form a grid-like frame structure, thereby jointly constituting multiple operating ports 3 distributed along a planar array.

[0066] The multifunctional floating structure of this embodiment can be easily modularized and expanded to form as many operating ports as possible, making it particularly suitable for use in aquaculture.

[0067] Furthermore, the two-way connector 7, several three-way connectors 4, and several four-way connectors 5 are preferably made of fiber-reinforced materials, specifically, by molding. Compared to synthetic foam and HDPE materials, composite materials have higher bending and deformation resistance.

[0068] Furthermore, to improve the structural strength of the multi-functional floating buoy structure, the buoy bodies 1 are also locked together by several sets of connecting support pipes 21, sets of buoy fasteners 22 and buoy fastener locking parts 23. Specifically, each connecting support pipe 21 is locked to the corresponding mounting flange 112 of the buoy body 1 by several sets of buoy fasteners 22 and buoy fastener locking parts 23, thereby forming a stable and reliable floating buoy structure.

[0069] Specifically, the float fastener 22 is a "U"-shaped fastener, and the float fastener locking part 23 can be a bolt and nut kit or a rivet, so that the float fastener 22 can be locked to the float body 1 in a very convenient and efficient manner.

[0070] Furthermore, the connecting support pipe 21 is continuously formed using a pultrusion process with fiber-reinforced material. This not only reduces the difficulty of the process but also increases the molding efficiency, thereby lowering the production cost of the connecting support pipe 21. The pontoon fastener 22 and the pontoon fastener locking element 23 are preferably formed using fiber-reinforced material, specifically, using a molding process. Compared to synthetic foam and HDPE materials, composite materials have higher bending and deformation resistance. To reduce costs, the pontoon fastener locking element 23 can also be made of stainless steel with good corrosion resistance.

[0071] Example 6:

[0072] Please see Figure 10 A multifunctional floating structure includes a top frame 6 and composite material pontoons of Embodiment 1. The top frame 6 is formed by multiple splicing pipes 61 locked together by several sets of splicing pipe fasteners 62 and splicing pipe fastener locking elements 63, and spliced ​​to form a grid-like frame structure. The frame structure has multiple operating ports 3 distributed along a plane array. Each pontoon body 1 is staggered from each operating port 3 and is arrayed at the bottom of the frame structure. All mounting flanges 112 of all pontoon bodies 1 are locked to at least two corresponding splicing pipes 61 by several sets of pontoon fasteners 22 and pontoon fastener locking elements 23, so that the mounting plane 111 of each pontoon body 1 abuts against the bottom surface of the corresponding splicing pipe 61.

[0073] The multifunctional floating structure of this embodiment can be expanded into an ultra-large floating structure, which is particularly suitable as a large-scale aquaculture platform.

[0074] Specifically, the float fastener 22 is a "U"-shaped fastener, and the float fastener locking part 23 can be a bolt and nut kit or a rivet, so that the float fastener 22 can be locked to the float body 1 in a very convenient and efficient manner.

[0075] Furthermore, the float fastener 22 and the float fastener locking element 23 are preferably made of fiber-reinforced material, specifically, by molding. Compared to synthetic foam and HDPE, composite materials have higher resistance to bending and deformation. To reduce costs, the float fastener locking element 23 can also be made of stainless steel with good corrosion resistance.

[0076] Similarly, the splicing pipe fastener 62 is a "U"-shaped fastener, and the splicing pipe fastener locking part 63 can be a bolt and nut kit or a rivet, so that each splicing pipe 61 can be locked together as one piece in a very convenient and efficient manner.

[0077] Furthermore, the splicing pipe 61 is continuously molded using a pultrusion process with fiber-reinforced material. This not only reduces the complexity of the process but also increases molding efficiency, thereby lowering the production cost of the splicing pipe 61. The splicing pipe fastener 62 and the splicing pipe fastener locking element 63 are preferably molded using fiber-reinforced material, specifically, using a compression molding process. Compared to synthetic foam and HDPE materials, composite materials have higher bending and deformation resistance. To reduce costs, the splicing pipe fastener locking element 63 can also be made of stainless steel with good corrosion resistance.

[0078] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model.

Each pontoon body (1) is staggered from each operating port (3) and is arrayed at the bottom of the frame structure. All mounting flanges (112) of all pontoon bodies (1) are fastened to at least two corresponding splicing pipes (61) by several sets of pontoon fasteners (22) and pontoon fastener locking elements (23), so that the mounting plane (111) of each pontoon body (1) abuts against the bottom surface of the corresponding splicing pipe (61).
