Description

Technical Field

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

[0002] Please refer to Chinese utility model patent application CN103895829A, which discloses a continuous pontoon composite material floating structure system. The pontoons are made of fiber-reinforced resin-based composite material, which, compared to synthetic foam and HDPE, has higher bending and deformation resistance, and can withstand the impact of typhoons and waves.

[0003] However, the ends of the pontoons require an integrally formed flange structure, which cannot be continuously formed using the pultrusion process, resulting in low manufacturing efficiency and high production costs. Furthermore, because the main structure of the pontoons is cylindrical, even though the pontoon connection units are equipped with pontoon connection units for installing the bridge deck structure system, and the top surface of the pontoon connection units is designed as a plane, the top surface area of ​​the pontoon connection units is very small, and the number of pontoon connection 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 and limiting its application and promotion.

[0004] Solving these problems is now a top priority. Utility Model Content

[0005] In view of this, the present invention provides a composite material shell, a spliced ​​pontoon and a floating structure.

[0006] The technical solution is as follows:

[0007] The first aspect of this application relates to a composite material cylindrical shell, comprising a cylindrical shell body continuously formed by pultrusion process using fiber reinforced material. The cylindrical shell body is a cylindrical structure extending in a horizontal direction, and has mounting openings at both ends in the length direction. The top of the cylindrical shell body has a planar mounting plane, which extends along the length direction to both ends of the cylindrical shell body. The mounting plane has mounting flanges protruding on both sides in the width direction of the cylindrical shell body.

[0008] The use of the above composite material shell, with its completely uniform structure along the length, is highly conducive to continuous molding of fiber-reinforced materials through pultrusion. This not only reduces the difficulty of the process but also increases molding efficiency, thereby lowering the production cost of the composite material shell. Furthermore, since the entire top surface of the shell is a planar mounting surface, it not only facilitates assembly and connection with the upper structure but also allows all mounting surfaces and flanges to support the upper structure, providing a large support area and significantly improving the load-bearing capacity and stability of the upper structure. This, in turn, greatly expands the application scenarios and enhances versatility.

[0009] The second aspect of this application relates to a splicing pontoon, comprising at least two of the aforementioned composite material shells and one more splicing plug than the number of composite material shells, wherein each shell body is arranged in a straight line along the length direction, thereby placing each mounting plane on the same plane.

[0010] The splicing plug includes a sealing partition, on both sides of which are integrally formed with plugs adapted to the installation opening. Adjacent shell bodies are connected by two plugs of a splicing plug embedded in the corresponding installation opening to form a sealed connection. The installation openings at the outer ends of the shell bodies at both ends are sealed by the plugs of a splicing plug, so that each shell body and the splicing plugs at both ends enclose a float cavity with a sealed chamber structure.

[0011] The above-mentioned modular pontoons not only possess all the advantages of the composite material hulls, but also allow for convenient and flexible assembly to obtain the required length of modular pontoons according to actual needs, further improving the versatility and ease of use of modular pontoons. At the same time, the assembly operation is simple and the assembly efficiency is high.

[0012] The third aspect of this application relates to a floating structure, including at least two sets of pipe connection assemblies arranged side by side and at least two sets of the above-mentioned spliced ​​pontoons. Each spliced ​​pontoon 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 spliced ​​pontoons and is locked to all mounting flanges of all spliced ​​pontoons by several sets of pontoon fasteners and pontoon fastener locking elements. There are gaps between adjacent pipe connection assemblies and between adjacent spliced ​​pontoons, thereby forming multiple operating ports distributed along a planar array.

[0013] The above-mentioned floating structure not only possesses all the advantages of the spliced ​​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.

[0014] The fourth aspect of this application relates to a floating structure, including at least two sets of pipe connection assemblies arranged side by side and at least two sets of the above-mentioned spliced ​​pontoons. Each spliced ​​pontoon is arranged side by side, and adjacent spliced ​​pontoons abut against each other through the outer edge of the mounting flange. Each pipe connection assembly includes a connecting plate perpendicular to the spliced ​​pontoon. Each connecting plate is fitted on the mounting plane of all spliced ​​pontoons and locked to all mounting flanges of all spliced ​​pontoons by a number of connecting plate locking members.

[0015] The above-mentioned floating hull structure not only possesses all the advantages of the aforementioned modular pontoons, but also can be used as various water platforms, offering excellent versatility, high structural strength, and good weather resistance. Furthermore, the floating hull structure can be modularly expanded, making it particularly suitable as a water operation platform.

[0016] The fifth aspect of this application relates to a floating structure comprising at least two sets of the aforementioned spliced ​​buoys, wherein each spliced ​​buoy is arranged side by side, and one row of mounting flanges between adjacent spliced ​​buoys presses against another row of mounting flanges, and all are locked together as one unit by a plurality of flange locking members.

[0017] The above-mentioned floating hull structure not only possesses all the advantages of the aforementioned modular pontoons, but also allows the floating hull structure to be used as various water platforms, offering excellent versatility, high structural strength, and good weather resistance. Furthermore, the floating hull structure can be modularly expanded, making it particularly suitable as a water operation platform. In addition, apart from the modular pontoons, the overall assembly only requires one component: the flange locking part, which significantly reduces the difficulty of component management and improves the assembly efficiency of the floating hull structure.

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

[0029] Example 1:

[0030] like Figure 1 As shown, a composite material cylindrical shell mainly includes a cylindrical shell body 11, which is a cylindrical structure extending in the horizontal direction. The cylindrical shell body 11 has installation openings 113 at both ends in the length direction. The structure of the cylindrical shell body 11 in the length direction is completely consistent. Therefore, the cylindrical shell body 11 is made of fiber reinforced material and continuously formed by pultrusion process, which not only has low process difficulty, but also high molding efficiency, thus reducing the production cost of the cylindrical shell body 11.

[0031] In this embodiment, a planar mounting surface 111 is formed on the top of the cylindrical shell body 11. The mounting surface 111 extends along the length direction to both ends of the cylindrical shell body 11. Mounting flanges 112 are formed on both sides of the mounting surface 111 along the width direction of the cylindrical shell body 11. Furthermore, the top surfaces of the two mounting flanges 112 in this embodiment are flush with the mounting surface 111. That is, the entire top surface of the float body 1 is a planar structure, which not only facilitates the assembly and connection with the upper structure, but also allows all the mounting surfaces 111 and mounting flanges 112 to support the upper structure, thereby providing a huge support area for the upper structure, greatly improving the load-bearing capacity and load-bearing stability of the upper structure, and thus greatly increasing the application scenarios and improving versatility.

[0032] Example 2:

[0033] like Figure 2 As shown, a composite material shell has the same main structure as in Example 1, except that the installation heights of the two mounting flanges 112 are different.

[0034] Specifically, the top surface of one mounting flange 112 is 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 shells to be directly assembled into one piece, forming an almost completely flat platform on its top surface, which is conducive to personnel movement. Please refer to Example 7 for details.

[0035] Example 3:

[0036] Please see Figures 1-6 A modular pontoon includes at least two composite material shells of Embodiment 1 or Embodiment 2, and one more splicing plug 12 than the number of composite material shells. Each shell body 11 is connected end-to-end via the splicing plug 12, thereby arranging the shell bodies 11 in a straight line along their length, and ensuring that all mounting surfaces 111 are on the same plane. Therefore, the modular pontoon of this embodiment can be easily and flexibly assembled to obtain a modular pontoon of the required length according to actual needs, further improving the versatility and ease of use of the modular pontoon. Simultaneously, the splicing operation is simple and the splicing efficiency is high.

[0037] The splicing plug 12 is made of fiber-reinforced material, specifically, it is made by molding process. Compared with synthetic foam and HDPE material, composite material has higher bending and deformation resistance.

[0038] Specifically, the splicing plug 12 includes a sealing partition 121. Both sides of the sealing partition 121 are integrally formed with plugs 122 that are adapted to the installation openings 113. Adjacent cylindrical bodies 11 are connected by two plugs 122 of a splicing plug 12 embedded in the corresponding installation openings 113 to form a sealed connection. The installation openings 113 at the outer ends of the cylindrical bodies 11 at both ends are sealed by plugs 122 of a splicing plug 12. Thus, each cylindrical body 11 and the splicing plugs 12 at both ends form a float cavity 1a with a sealed chamber structure. 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 splicing float can serve as an excellent buoyancy-providing device.

[0039] Furthermore, since the modular pontoon has multiple pontoon cavities 1a, even if one or more pontoon cavities 1a are damaged by air leakage, the remaining pontoon cavities 1a can still provide sufficient buoyancy for the modular pontoon.

[0040] Furthermore, both sides of the sealing baffle 121 are integrally formed with annular outer baffles 123 surrounding the corresponding plugs 122. Each annular outer baffle 123 forms an annular fitting gap 124 with the corresponding plug 122 that is adapted to the end of the cylindrical shell body 11. The end of each cylindrical shell body 11 is embedded in the corresponding annular fitting gap 124. That is, the thickness of each position of the end of the cylindrical shell body 11 matches the width of each position of the annular fitting gap 124, which can effectively improve the sealing performance of the installation.

[0041] Furthermore, all plugs 122 are thin-walled annular structures, thus achieving a lightweight design for the spliced ​​plugs 12 and improving the buoyancy of the spliced ​​pontoons.

[0042] Furthermore, since the splicing plug 12 may need to be disassembled and reassembled frequently, in order to ensure the reliability of the installation of the splicing plug 12 and the airtightness of the float cavity 1a, 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.

[0043] Furthermore, at least one sealed inner liner 13 is installed in the float cavity 1a, so that the sealed inner liner 13 can be easily disassembled and assembled by disassembling and assembling the splicing plug 12. At the same time, by adding the sealed inner liner 13, effective buoyancy can still be provided when the shell body 11 leaks, which plays a double insurance role.

[0044] Similarly, the sealed inner liner 13 can be filled with air or a lighter inert gas such as helium, thus enabling the modular pontoon to serve as an excellent buoyancy-providing device.

[0045] 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 spliced ​​float to provide sufficient buoyancy.

[0046] 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.

[0047] 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).

[0048] 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.

[0049] Example 4:

[0050] Please see Figure 7 A floating structure includes at least two sets of pipe connection assemblies 2 arranged side by side and at least two sets of spliced ​​pontoons of embodiment 3. Each spliced ​​pontoon 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 spliced ​​pontoons and is locked to all mounting flanges 112 of all spliced ​​pontoons by several sets of pontoon fasteners 22 and pontoon fastener locking parts 23, thereby forming a stable and reliable floating structure.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Example 5:

[0055] Please see Figure 8 A floating structure, whose main structure is exactly the same as that of Embodiment 4, the difference is that: the outermost pipe connection component 2 is provided with two connecting support pipes 21, and the two connecting support pipes 21 of the outermost pipe connection component 2 are connected by several pedal connectors to multiple pedals 24 evenly distributed between each adjacent spliced ​​float, so as to facilitate the movement of personnel on the floating raft.

[0056] 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.

[0057] The pedal connector is preferably fixed with fiber-reinforced cable ties or ropes, which is simple, reliable, and highly corrosion-resistant.

[0058] Example 6:

[0059] Please see Figure 9 A floating structure includes at least two sets of pipe connection assemblies 2 arranged side by side and at least two sets of spliced ​​pontoons of embodiment 3. The spliced ​​pontoons are arranged side by side, and adjacent spliced ​​pontoons abut against each other through the outer edge of mounting flange 112. Each pipe connection assembly 2 includes a connecting plate 25 perpendicular to the spliced ​​pontoon. Each connecting plate 25 is fitted on the mounting plane 111 of all spliced ​​pontoons. Furthermore, each connecting plate 25 is locked to all mounting flanges 112 of all spliced ​​pontoons by a plurality of connecting plate locking members 26.

[0060] The top surface of the 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 waterborne operation platform.

[0061] 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.

[0062] 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.

[0063] Example 7:

[0064] Please see Figure 10 A floating structure includes at least two sets of spliced ​​buoys as described in Embodiment 3, with each spliced ​​buoy arranged side by side, and the composite material shell adopting Embodiment 2.

[0065] Therefore, one row of mounting flanges 112 between adjacent spliced ​​pontoons presses onto another row of mounting flanges 112, and both are locked together as one unit by several flange locking parts 27. The top surface of the 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.

[0066] 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.

[0067] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
