Description

Technical Field

[0001] The present application relates to the field of offshore floating platform equipment, and in particular to a triangular structure floating platform. Background Art

[0002] As a key facility for marine resource development and offshore wind power industry, the installation convenience, economy and adaptability of offshore floating platforms have always been important considerations in engineering design and construction.

[0003] Traditional offshore floating platforms lack design flexibility, making them difficult to adapt to the specific conditions of different sea areas. They also often lack scalability, making them unable to meet the future development needs of industries like offshore wind power. Therefore, developing a new floating structure to improve the installation convenience, adaptability, and scalability of offshore floating platforms has become a pressing issue in the field of marine engineering. Utility Model Content

[0004] In order to improve the problem that existing offshore floating platforms are difficult to assemble, the present application provides a triangular structure floating platform.

[0005] The triangular structure floating platform provided in this application adopts the following technical solutions:

[0006] A triangular structure floating platform comprising

[0007] The floating platform comprises a bending portion and two extension portions, wherein the two extension portions are symmetrically arranged on the bending portion via a symmetry axis;

[0008] There are three buoys, all of which are arranged on the top of the floating platform, one of which is arranged on the bending portion, and the other two buoys are symmetrically arranged on one end of the two extensions away from the bending portion through the symmetry axis.

[0009] By adopting the above technical solution, the triangular structure floating platform can be installed in a wider water depth range and can be assembled in the port and towed by a tugboat. For example, the bending portion and the two extension portions can be transported to the dock, and the corresponding buoys are first installed on the bending portion and the two extension portions, and then the floating platform is assembled. After the assembly of the floating platform is completed, it can be placed in the sea to complete the assembly; or after all the components of the triangular structure floating platform are transported to the location, the corresponding buoys are installed on the bending portion and the two extension portions, and then the floating platform is assembled. After the assembly of the floating platform is completed, it can be placed in the sea to complete the assembly; the modular setting of the triangular structure floating platform installation improves the problem that the existing offshore floating platform is inconvenient to assemble.

[0010] Preferably, the extension portion includes several concrete cylinder sections.

[0011] By adopting the above technical solution, the modular design of the concrete cylinder sections allows them to be assembled at a port or dock, and then towed as a whole to the offshore installation site and placed into the sea after forming a whole, further improving the problem of inconvenient assembly of existing offshore floating platforms.

[0012] Preferably, each concrete cylinder segment is connected to the adjacent concrete cylinder segment via a steel strand.

[0013] By adopting the above technical solution, several concrete cylinder sections can be quickly connected using steel strands.

[0014] Preferably, the concrete cylinder section is made by casting UHPC high-performance concrete.

[0015] By adopting these technical solutions, UHPC high-performance concrete achieves higher compressive, tensile, and flexural strength than conventional concrete, enabling it to withstand the extreme loads and stresses found in marine environments. Furthermore, UHPC high-performance concrete is extremely durable, resisting chloride ion penetration, sulfate attack, and freeze-thaw cycles, effectively extending the service life of concrete cylinder segments.

[0016] Preferably, the bending portion is made by casting UHPC high-performance concrete, and both ends of the bending portion are respectively connected to one end of the two extension portions away from the corresponding buoys.

[0017] By adopting this technical solution, UHPC high-performance concrete possesses higher compressive, tensile, and flexural strength than traditional concrete, capable of withstanding the extreme loads and stresses found in marine environments. Furthermore, UHPC high-performance concrete is extremely durable, resisting chloride ion penetration, sulfate attack, and freeze-thaw cycles, effectively extending the service life of the bend. The bend and extension, when connected, form a stable triangular structure, ensuring the triangular floating platform's balance on the sea surface and facilitating the transmission and dispersion of forces generated by wind turbines, as well as external forces caused by waves, wind, and other environmental factors.

[0018] Preferably, the three buoys have the same specifications, and one end of the buoy arranged at the bent portion away from the floating platform is connected to the bottom of the fan.

[0019] By adopting the above technical solution, the three buoys have the same specifications, ensuring that the buoyancy is evenly distributed at the three corners of the triangular structure floating platform, helping to maintain the horizontal balance of the triangular structure floating platform and reducing the risk of the triangular structure floating platform tilting or capsizing.

[0020] Preferably, a connecting beam is further included, with two ends of the connecting beam respectively connected to two buoys arranged on the two extension parts to increase the stability of the floating platform.

[0021] By adopting the above technical solution, the connecting beam connects the pontoons on the two extension parts to form a more stable structural frame, which helps to resist the swaying and tilting caused by environmental factors such as waves and wind, and enhances the stability of the overall structure.

[0022] Preferably, the connecting beam is further provided with a support rod, and two support rods are provided. The two support rods are respectively connected to the connecting beam and the corresponding buoy to enhance the bending resistance and torsional resistance of the connecting beam.

[0023] By adopting the above technical solution, the support rods are connected to the connecting beams and the corresponding pontoons to form a more robust structure, which significantly improves the strength of the connecting beams. This helps to provide additional support force when the connecting beams are subjected to bending moments, reduces the bending deformation of the beams, and helps to resist possible torsion of the connecting beams, thereby enhancing the torsional stability of the entire structure.

[0024] Preferably, it further comprises a seabed anchor chain, which is connected to the floating platform and is used to connect the floating platform and the seabed to limit the position of the floating platform.

[0025] By adopting the above technical solution, the submarine anchor chain firmly connects the floating platform to the seabed, ensuring the stability of the floating platform in the predetermined position and preventing displacement caused by natural forces such as wind and waves; and the submarine anchor chain can limit the horizontal and vertical movement of the triangular structure floating platform, significantly improving the stability of the triangular structure floating platform and enabling it to withstand the impact of harsh marine environments.

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a triangular structure floating platform.

[0037] Example 1

[0038] Reference Figure 1 The triangular structure floating platform includes a floating platform 2, a pontoon 3 and a connecting beam 4, and a wind turbine 1 is provided on the triangular structure floating platform.

[0039] like Figure 2 and Figure 3 As shown, the floating platform 2 includes a bending portion 21 and two extension portions 22. The bending portion 21 and the two extension portions 22 are both made of UHPC high-performance concrete. The two extension portions 22 are symmetrically arranged at both ends of the bending portion 21 through the symmetry axis 9. The two ends of the bending portion 21 are respectively connected to one end of the two extension portions 22. Since the floating platform 2 adopts a modular combination of the bending portion 21 and the two extension portions 22, the staff can assemble the floating platform 2 at different positions according to actual needs, which improves the problem that the existing offshore floating platforms are inconvenient to assemble.

[0040] For example, if the triangular structure floating platform needs to be assembled and / or debugged at a dock or port, the user can transport the bent portion 21 and two extensions 22 to the dock or port for assembly. Compared to existing offshore floating platforms that require direct transportation of the entire floating platform 2, the modular combination of the bent portion 21 and two extensions 22 allows the bent portion 21 and the extensions 22 to be transported separately, thus reducing reliance on large transportation vehicles and lowering overall transportation costs.

[0041] Furthermore, modular transportation reduces the risk of damage to large components like Floating Platform 2 during transport, and also mitigates the risk of project delays due to transportation issues. Assembly at a dock or port can utilize existing port facilities and machinery, simplifying the assembly process and accelerating construction. Furthermore, assembly work on land is safer and more convenient than offshore, minimizing the potential inconveniences workers may experience in the marine environment when assembling the triangular floating platform, such as rough seas or extreme weather conditions, thus addressing the difficulty of assembling existing offshore floating platforms.

[0042] It should be noted that UHPC high-performance concrete has higher compressive, tensile, and flexural strength than traditional concrete, and can withstand the extreme loads and stresses in marine environments. Furthermore, UHPC high-performance concrete is extremely durable, resisting chloride ion penetration, sulfate attack, and freeze-thaw cycles, effectively extending the service life of the bend 21 and extension 22. The connection between the bend 21 and extension 22 forms a stable "V" shape, ensuring the balance of the triangular floating platform on the sea surface and facilitating the transmission and dispersion of the forces generated by the wind turbine 1, as well as external forces caused by waves, wind, and other environmental factors.

[0043] Optionally, the bending portion 21 and the extending portion 22 can be made of solid buoyancy materials and / or metal materials according to actual construction requirements.

[0044] like Figure 3 and Figure 4 As shown, the extension 22 is constructed by connecting several concrete segments 23. Each concrete segment 23 is connected to its adjacent concrete segment 23 via steel strands. The connected extension 22 is then connected to the bent portion 21 via steel strands, forming a complete floating platform 2. The modular design of the concrete segments 23 allows the floating platform 2 to be assembled at a port or dock and then transported as a single unit, simplifying the construction process and reducing the risks of offshore operations.

[0045] Optionally, flanges are pre-buried at both ends of each concrete cylinder segment 23 , and the flanges of each concrete cylinder segment 23 can be welded to the flanges of adjacent concrete cylinder segments 23 to ensure the structural strength of the floating platform 2 .

[0046] Compared with the existing offshore floating platform 2, smaller modules such as the concrete barrel section 23 and the bend section 21 can be prefabricated in different factories, enabling the parallel manufacturing of multiple modules of the floating platform 2, significantly shortening the construction period of the entire project; the concrete barrel section 23 and the bend section 21 can also be selected from a wider range of transportation routes and methods, including roads, railways and smaller ships, which improves transportation flexibility.

[0047] In this embodiment, the cross-sectional width of the concrete cylinder segment 23 is 13m, the height of the concrete cylinder segment 23 is 6.5m, the wall thickness around the cross-sectional area is 60cm, and the thickness of the middle wing wall is 40cm, thereby improving the durability and shear resistance of the concrete cylinder segment 23. The surface of the concrete cylinder segment 23 is smooth, and the cross-sectional area of ​​the concrete cylinder segment 23 is rectangular with rounded corners.

[0048] like Figure 3 As shown, the three pontoons 3 have the same specifications, and the bottoms of the three pontoons 3 are connected to the top of the floating platform 2. The three pontoons 3 are respectively located at the bending portion 21 and the two extension portions 22 at one end away from the bending portion 21, so as to ensure that the buoyancy is evenly distributed at the three corners of the triangular structure floating platform, which helps to maintain the horizontal balance of the triangular structure floating platform and reduce the risk of the triangular structure floating platform tilting or capsizing.

[0049] The bottom of the wind turbine 1 is connected to the top of the pontoon 3 located on the bend 21. The ends of the connecting beam 4 are connected to the two pontoons 3 located on the two extensions 22. This ensures that the weight of the floating platform 2 is properly distributed and reduces structural stress caused by uneven weight. Furthermore, the floating platform 2, the two pontoons 3, and the connecting beam 4 form a stable triangular framework, significantly improving overall stability. The modular design allows the wind turbine 1, connecting beam 4, and pontoons 3 of the triangular floating platform to be pre-assembled at the port. After the triangular floating platform is assembled, it can be moved by tugboat, simplifying the offshore construction process.

[0050] Optionally, the bent portion 21 may be made of solid buoyancy material and / or metal material according to actual construction requirements to further provide buoyancy for the wind turbine 1 .

[0051] Specifically, the connecting beam 4 is connected to the two pontoons 3 to form a triangular door structure. The connecting beam 4 is also provided with two support rods 5, which are respectively connected to the connecting beam 4 and the corresponding pontoons 3, so that the connecting beam 4, the support rods 5 and the corresponding pontoons 3 form a triangular structure, which significantly improves the strength of the connecting beam 4, helps to provide additional support force when the connecting beam 4 is subjected to bending moment, reduces the bending deformation of the beam, and helps to resist the possible torsion of the connecting beam 4, thereby enhancing the torsional stability of the entire structure.

[0052] Optionally, the float 3 can be made of solid buoyancy materials and / or metal materials according to actual construction needs to further provide buoyancy for the wind turbine 1; connecting parts made of solid buoyancy materials and / or metal materials can be set on the outer wall of the float 3 according to actual construction needs to be connected to the connecting beam 4 through the connecting parts.

[0053] refer to Figure 1One end of the submarine anchor chain 6 is connected to the floating platform 2, and the other end of the submarine anchor chain 6 is provided with an anchor head 7. The user can fix the anchor head 7 on the seabed or insert it into the seabed, and realize the connection between the seabed or the seabed and the floating platform 2 through the submarine anchor chain 6, thereby ensuring the stability of the floating platform in a predetermined position and preventing displacement caused by natural forces such as wind and waves; and the submarine anchor chain 6 can limit the horizontal and vertical movement of the triangular structure floating platform, significantly improving the stability of the triangular structure floating platform, so that it can withstand the influence of harsh marine environment.

[0054] It should be noted that the specifications of the various components of the triangular structure floating platform in the present application need to be set according to actual conditions, and the present application does not impose any specific restrictions. For ease of understanding, the specifications of the triangular structure floating platform of Example 1 of the present application are exemplified below: In Example 1, the height of the pontoon 3 is 30m, and the projection shape of the pontoon 2 after being connected to the connecting beam 4 is approximately an equilateral triangle. The length of the connection between the central axes of the two pontoons 3 arranged in the extension part 22 is 94m, and the length of the connection between the central axes of the pontoon 3 arranged in the bending part 21 and one of the pontoons 3 arranged in the extension part 22 is 94m. The length of the concrete barrel section 23 is 20m. The concrete barrel section 23 can be obtained by prefabricated components to meet the required length of the triangular structure floating platform.

[0058] It should be noted that the specifications of the various components of the triangular structure floating platform in the present application need to be set according to actual conditions, and the present application does not impose any specific restrictions. For ease of understanding, the specifications of the triangular structure floating platform of Example 2 of the present application are exemplified below: the height of the pontoon 3 is 25m, and the projection shape of the pontoon 2 after being connected to the connecting beam 4 is approximately an isosceles triangle. The length of the connection between the central axes of the two pontoons 3 arranged in the extension part 22 is 108m, and the length of the connection between the central axes of the pontoon 3 arranged in the bending part 21 and one of the pontoons 3 arranged in the extension part 22 is 105m. The length of the concrete barrel section 23 is 15m. The concrete barrel section 23 can be obtained by prefabricated components to meet the required length of the triangular structure floating platform.

[0059] Example 3

[0060] Reference Figure 8 The difference between this embodiment and embodiment 1 is that there are three extension parts 22 and three bending parts 21, and the three extension parts 22 are connected to adjacent extension parts 22 through corresponding bending parts 21; and, embodiment 3 is not provided with connecting beams 4 and support rods 5, and three pontoons 3 are respectively provided on the corresponding bending parts 21, and each pontoon 3 is provided with a crash shell 8.

[0061] It should be noted that the specifications of the various components of the triangular structure floating platform in this application need to be set according to actual conditions, and this application does not impose specific restrictions. For ease of understanding, the specifications of the triangular structure floating platform of Example 3 of this application are given as an example below: the height of the pontoon 3 is 25m, the length of the central axis connection of the two pontoons 3 arranged at the bending portion 21 is 108~112m, and the length of the concrete barrel section 23 is 10m. The concrete barrel section 23 can be obtained in the form of prefabricated components to meet the required length of the triangular structure floating platform.
