Description

Technical Field

[0001] This invention relates to the field of floating marine structure technology, and in particular to a floating platform mooring device and mooring system. Background Technology

[0002] With the rapid advancement of marine new energy and integrated water development projects, these projects have developed rapidly, leading to the large-scale promotion of floating structures such as floating photovoltaic arrays, floating wind power foundations, and offshore floating work platforms. Floating structures operate in complex marine environments, subjected to multiple loads from sea winds, waves, currents, and tides. They typically rely on mooring systems to maintain positioning, control the drift and torsion of the floating body, and ensure the stable operation of the onboard equipment.

[0003] In existing technologies, most mooring systems use metal anchor chains with excellent wear resistance and UV aging resistance as the core load-bearing components. These metal anchor chains can transfer the load between the floating platform and the underwater anchor foundation. However, metal anchor chains lack elastic buffering performance. When wind and waves generate instantaneous impact loads, the impact stress is directly concentrated at the floating connection nodes and the underwater anchor foundation, which can easily cause deformation of the floating body and fatigue failure of mooring components. In addition, the metal anchor chains have a large self-weight, which will form a continuous vertical additional load at the edge of the floating body, exacerbating the local pressure on the floating body, leading to stress imbalance of the floating body, and causing problems such as platform tilting and insufficient anchoring stability.

[0004] Therefore, there is an urgent need for a floating platform mooring device and mooring system to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a mooring device and system for a floating platform, which can buffer impact loads through adaptive movement, effectively prevent deformation of the floating platform, effectively reduce the consumption of buoyancy by its own weight, and improve the force balance and dwelling stability of the floating platform.

[0006] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, a mooring device for a floating platform is provided, which floats on the sea surface and is disposed at the corner of a floating platform. The mooring device for the floating platform includes: The connecting assembly includes two truss connectors, which are arranged at an angle and connected to the two sides of the corner of the floating platform in a corresponding manner. The two truss connectors are hinged to each other to form a hinge node. The tensioning assembly includes a first tensioning member and two second tensioning members. One end of each of the two second tensioning members is connected to one of the two truss connectors. The other end of each of the two second tensioning members is connected to the first end of the first tensioning member. The second end of the first tensioning member is hinged to the hinge node. The first end of the first tensioning member can be connected to the anchor foundation. A hollow buoyancy-enhancing component is installed in the first tensioning component to increase the buoyancy of the first tensioning component.

[0007] Optionally, the first tension piece has a recessed area, and the hollow float-enhancing piece is set in the recessed area.

[0008] Optionally, the hollow buoyancy enhancer includes multiple hollow sections, which are arranged symmetrically about the axis of the first tensioning member.

[0009] Optionally, the truss connector includes a hinged connection and a truss body. The hinged node is formed at one end of the hinged connection, and the other end of the hinged connection is connected to the truss body. The truss body is connected to the corresponding second tension member and the corresponding side.

[0010] Optionally, the cross-sectional shape of the truss body is triangular, and the truss body is provided with a first connecting part, a second connecting part and a third connecting part arranged in a triangular pattern. The first connecting part is connected to the corresponding side, and the second connecting part and the third connecting part are both connected to the corresponding second tension member.

[0011] Optionally, the second tension member includes a first tension cable and a second tension cable. One end of the first tension cable is connected to the second connecting part, and the other end is connected to the first end of the first tension member. One end of the second tension cable is connected to the third connecting part, and the other end is connected to the first end of the first tension member.

[0012] Optionally, the connecting assembly also includes an elastic connecting cable, one end of which is connected to the first connecting part and the other end of which is connected to the floating platform.

[0013] Optionally, the floating platform mooring device also includes a mooring cable, one end of which can be connected to the anchor foundation and the other end of which is connected to the first end of the first tensioning member.

[0014] Optionally, the first end of the first tension member is provided with a connecting shaft, which passes through the two truss connectors and is rotatably engaged with both truss connectors.

[0015] Secondly, a mooring system is provided, including a plurality of floating platform mooring devices according to the first aspect. The floating platform includes a plurality of corners, and the plurality of floating platform mooring devices are respectively disposed at the plurality of corners of the floating platform.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a mooring device and system for a floating platform. The load of the floating platform is applied to the anchor foundation sequentially through truss connectors, a second tension member, and a first tension member, thus achieving positioning constraints on the floating platform. The two truss connectors are hinged to each other, and the first tension member is hinged to the hinge joints of the two truss connectors. This gives the floating platform mooring device the ability to deflect angles, allowing it to absorb impact loads through adaptive movement under the instantaneous impact of wind and waves, preventing platform deformation and extending its service life. The truss connectors utilize a truss structure. On one hand, compared to solid structures, truss structures have lower self-weight, effectively reducing the buoyancy loss due to their weight. On the other hand, the truss structure allows for multi-point load distribution, reducing localized pressure on the floating platform, balancing stress, and improving the stability of the floating platform while ensuring positioning constraints. The hollow buoyancy-enhancing component, with its hollow structure, increases the volume of seawater occupied by the first tensioning component while not significantly increasing the weight of the floating platform mooring device. This increases the buoyancy of the first tensioning component, improving the stress balance and stability of the floating platform. Furthermore, by incorporating the truss connector and the hollow buoyancy-enhancing component, the self-weight of the floating platform mooring device significantly reduces the buoyancy loss, allowing it to float on the sea surface at the same level as the floating platform. This further enhances the rationality and effectiveness of load transfer between the floating platform mooring device and the floating platform. Attached Figure Description

Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0023] Example 1 like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a floating platform mooring device 20, which can buffer impact loads through adaptive movement, effectively prevent deformation of the floating platform 10, and effectively reduce the consumption of buoyancy by its own weight, thereby improving the force balance and mooring stability of the floating platform 10.

[0024] See Figure 1 The floating platform mooring device 20 floats on the sea surface and is located at the corner of the floating platform 10. The floating platform mooring device 20 includes a connecting assembly 100, a tensioning assembly 200, and a hollow buoyancy-enhancing component 300. The connecting assembly 100 includes two truss connectors 110, which are arranged at an included angle and connected to the two sides of the corner of the floating platform 10 respectively. The two truss connectors 110 are hinged to each other to form a hinged node. The tensioning assembly 200 includes... The first tension member 210 and two second tension members 220 are connected at one end to two truss connectors 110 respectively, and at the other end of each of the two second tension members 220 is connected to the first end of the first tension member 210. The second end of the first tension member 210 is hinged to the hinge node, and the first end of the first tension member 210 can be connected to the anchor foundation. The hollow buoyancy-enhancing component 300 is provided on the first tension member 210 to increase the buoyancy of the first tension member 210.

[0025] The first end and the second end are the two ends of the first tensioning member 210 along its extension direction, respectively.

[0026] The floating platform mooring device 20 provided in this embodiment allows the load of the floating platform 10 to be applied to the anchorage foundation sequentially through the truss connector 110, the second tension member 220, and the first tension member 210, thus achieving positioning constraints on the floating platform 10. The two truss connectors 110 are hinged to each other, and the first tension member 210 is hinged to the hinge joints of the two truss connectors 110. This gives the floating platform mooring device 20 the ability to deflect angles, allowing it to absorb impact loads through adaptive movement under the instantaneous impact of wind and waves, preventing deformation of the floating platform 10 and extending its service life. The truss connector 110 adopts a truss structure. On the one hand, compared with a solid structure, the truss structure has a smaller self-weight, which can effectively reduce the consumption of buoyancy by the self-weight of the truss connector 110. On the other hand, the truss structure can realize the multi-point distribution of the load of the floating platform 10, reduce the local pressure on the floating platform 10, and balance the force on the floating platform 10. While ensuring the safety of positioning constraints, it improves the stability of the floating platform 10's stay. The hollow buoyancy-enhancing component 300 is a hollow structure. It can increase the volume of seawater occupied by the first tensioning component 210 without significantly increasing the weight of the floating platform mooring device 20, thereby increasing the buoyancy of the first tensioning component 210 and improving the force balance and stay stability of the floating platform 10. Furthermore, by setting the truss connector 110 and the hollow buoyancy-enhancing component 300, the consumption of buoyancy by the self-weight of the floating platform mooring device 20 in this embodiment can be significantly reduced, enabling the floating platform mooring device 20 in this embodiment to float on the sea surface and be at the same level as the floating platform 10. This helps to further improve the rationality and effectiveness of load transfer between the floating platform mooring device 20 and the floating platform 10 in this embodiment.

[0027] For example, the floating platform 10 has a polygonal cross-sectional shape and multiple corners. The floating platform mooring device 20 of this embodiment can be installed at any corner of the floating platform 10.

[0028] For example, the anchor foundation is fixed to the seabed or bottom, which can fix the floating platform mooring device 20 of this embodiment in a specific sea area to achieve positioning constraint on the floating platform 10.

[0029] In this embodiment, see Figure 1 The first end of the first tension member 210 is provided with a connecting shaft 211, which passes through the two truss connectors 110 and is rotatably engaged with both truss connectors 110. This arrangement realizes the hinged connection between the two truss connectors 110 and the rotatable connection between the first tension member 210 and the two truss connectors 110.

[0030] Specifically, the first end of the first tension member 210 is provided with a mounting groove, the connecting shaft 211 is disposed in the mounting groove, the end of the truss connector 110 is located in the mounting groove and is fitted or clearance-fitted with the groove wall of the mounting groove, the truss connector 110 is provided with a connecting hole, the connecting shaft 211 passes through the connecting hole of the two truss connectors 110 and is rotatably fitted with the connecting hole. The groove wall of the mounting groove can constrain the displacement of the end of the truss connector 110, so that the truss connector 110 can only rotate relative to the connecting shaft and cannot move along the axial direction of the connecting shaft, thereby improving the reliability of the connection between the truss connector 110 and the first tension member 210.

[0031] Optionally, see Figure 1 The first tension member 210 has a recess 213, and a hollow buoyancy enhancer 300 is disposed within the recess 213. The recess 213 reduces the overall weight of the first tension member 210, thus reducing the buoyancy loss due to its weight. Simultaneously, although the recess 213 reduces the volume of seawater occupied by the first tension member 210, the hollow buoyancy enhancer 300 within the recess 213 prevents seawater from entering, ensuring that the buoyancy of the first tension member 210 is not significantly reduced due to the recess 213. This embodiment reduces the buoyancy loss due to the weight of the first tension member 210 while simultaneously ensuring the buoyancy received by the first tension member 210, reducing local pressure on the floating platform 10, preventing the floating platform 10 from tilting, and improving the force balance and stability of the floating platform 10.

[0032] In this embodiment, the recessed position 213 includes, but is not limited to, grooves and holes.

[0033] Optionally, see Figure 1 The hollow buoyancy-enhancing component 300 includes multiple hollow portions 310, which are symmetrically arranged about the axis of the first tensioning component 210. The symmetrical arrangement of the multiple hollow portions 310 increases the buoyancy of the first tensioning component 210 while ensuring that the first tensioning component 210 is subjected to symmetrical forces, thereby improving the stability of the first tensioning component 210.

[0034] For example, the first tension member 210 is made of I-beam, and two grooves are formed between the web and the flange of the I-beam, which are symmetrically arranged about the web. The recess 213 includes two grooves. The hollow part 310 is made of pontoons, and multiple pontoons are provided in each groove. The multiple pontoons are spaced apart along the extension direction of the first tension member 210.

[0035] Optionally, see Figure 1The truss connector 110 includes a hinged connection portion 111 and a truss body 112. The hinged node is formed at one end of the hinged connection portion 111, and the other end of the hinged connection portion 111 is connected to the truss body 112. The truss body 112 is connected to the corresponding second tension member 220 and the corresponding side. This configuration ensures that the truss body 112, which is only connected to the second tension member 220 and the side, is a truss structure, while the hinged connection portion 111 can be a solid structure. This balances the forces on the floating platform 10, reduces the buoyancy loss due to its own weight, and ensures the connection strength at the hinged connection of the truss connector 110, thereby improving the overall reliability of the floating platform mooring device 20.

[0036] For example, see Figure 1 The hinged connection 111 is made of steel plate, and the connecting shaft 211 on the first tension member 210 is rotatably inserted through the hinged connection 111.

[0037] In this embodiment, see Figure 1 and Figure 2 The truss body 112 has a triangular cross-sectional shape. A first connecting part 113, a second connecting part 114, and a third connecting part 115, arranged in a triangular pattern, are provided on the truss body 112. The first connecting part 113 connects to the corresponding side, and the second connecting part 114 and the third connecting part 115 both connect to the corresponding second tension member 220. The triangular cross-sectional structure of the truss body 112 improves the overall lateral stiffness and torsional resistance of the truss body 112, extending its service life. Furthermore, it allows for the reasonable distribution of loads within the truss body 112, balancing the forces on the floating platform 10, avoiding stress concentration, and improving the stability of the floating platform 10.

[0038] Specifically, the truss body 112 includes multiple chords and multiple web members. The first connection 113, the second connection 114 and the third connection 115 are provided at the connection between the chords and the web members, so that the external load can be directly transferred to each member from the intersection node, avoiding additional bending moment in the chord body, reducing local stress and improving the reliability of the structural connection.

[0039] The use of multiple chord members and multiple web members to form a truss structure with a triangular cross-section is an existing technology in this field and will not be described in detail here.

[0040] For example, both the chord members and the web members are made of hollow steel tubes. This arrangement helps to reduce the self-weight of the truss body 112, reduce the consumption of buoyancy by the self-weight of the truss body 112, and improve the stability of the floating platform 10 during its stay.

[0041] In some embodiments, see Figure 1 and Figure 2Multiple first connecting parts 113, second connecting parts 114, and third connecting parts 115 are provided. Multiple first connecting parts 113 are arranged at intervals along the extension direction of the truss main body 112 and correspond one-to-one with multiple second connecting parts 114. Multiple second connecting parts 114 correspond one-to-one with multiple third connecting parts 115. This arrangement allows for balanced multi-point load transfer between the floating platform 10 and the tensioning assembly 200, effectively avoiding stress concentration and improving the stability of the floating platform 10 during its stay.

[0042] In some embodiments, see Figure 1 and Figure 2 The second tension member 220 includes a first tension cable 221 and a second tension cable 222. One end of the first tension cable 221 is connected to the second connecting part 114, and the other end is connected to the first end of the first tension member 210. One end of the second tension cable 222 is connected to the third connecting part 115, and the other end is connected to the first end of the first tension member 210. This arrangement allows the truss body 112 to form a triangular structure with the first tension cable 221 and the second tension cable 222. The load can be distributed from multiple points on the triangular truss body 112 to the first tension member 210, balancing the force on the floating platform 10. This not only improves the overall strength of the floating platform mooring device 20 but also enhances the stability of the floating platform 10 during its stay.

[0043] The first cable 221 and the second cable 222 are used for tensioning and are both elastic, which enables the floating platform mooring device 20 of this embodiment to have flexible deformation capabilities. Thus, under the instantaneous impact of wind and waves, the floating platform mooring device 20 of this embodiment can buffer the impact load through adaptive movement, effectively avoid deformation of the floating platform 10, and extend the service life of the floating platform mooring device 20 of this embodiment.

[0044] For example, both the first cable 221 and the second cable 222 can be made of steel strand or cable.

[0045] For example, both the second connecting portion 114 and the third connecting portion 115 adopt connecting lugs.

[0046] Specifically, the first tension cable 221 is connected to the upper end of the first tension member 210, and the second tension cable 222 is connected to the lower end of the first tension member 210, so that the first tension member 210 can be subjected to force evenly from top to bottom, avoid excessive local stress, and improve the overall stability of the tensioning assembly 200.

[0047] For example, see Figure 1 and Figure 3Anchors 214 are provided on both the upper and lower surfaces of the first tension member 210. The first tension cable 221 is anchored to the anchor 214 located on the upper surface of the first tension member 210, and the second tension cable 222 is anchored to the anchor 214 located on the lower surface of the first tension member 210.

[0048] In some embodiments, see Figure 1 The connecting component 100 also includes an elastic connecting cable 120, one end of which is connected to the first connecting portion 113, and the other end is connected to the floating platform 10. The elastic connecting cable 120 is elastic, enabling the floating platform mooring device 20 of this embodiment to have flexible deformation capabilities. Therefore, under the instantaneous impact of wind and waves, the floating platform mooring device 20 of this embodiment can buffer the impact load through adaptive movement, effectively preventing deformation of the floating platform 10 and extending the service life of the floating platform mooring device 20 of this embodiment.

[0049] For example, the resilient connecting cable 120 is made of steel strand or cable.

[0050] In some embodiments, see Figure 1 The cross-sectional area of ​​the end of the truss main body 112 connected to the hinged connection 111 is larger than the cross-sectional area of ​​the end of the truss main body 112 away from the hinged connection 111, and the cross-sectional area of ​​the truss main body 112 gradually decreases from the end connected to the hinged connection 111 to the end away from the hinged connection 111. In other words, the truss main body 112 in this embodiment is a variable cross-section structure, and the cross-sectional area gradually decreases along the direction away from the hinged connection 111. This design helps to reduce the overall self-weight of the truss connector 110, further reducing the consumption of buoyancy by self-weight, ensuring that the floating platform mooring device 20 can be on the same horizontal plane as the floating platform 10, and improving the rationality and effectiveness of load transfer between the two.

[0051] Optionally, see Figure 1 The floating platform mooring device 20 also includes a mooring cable 400, one end of which can be connected to the anchor foundation and the other end of which is connected to the first end of the first tension member 210, so that the floating platform mooring device 20 of this embodiment is fixed in a specific sea area, thereby improving the stability of the floating platform 10 floating at sea.

[0052] For example, the mooring cable 400 includes, but is not limited to, anchor chains, cables, and combinations of anchor chains and cables, as long as the mooring cable 400 has tension that reliably connects the connecting assembly 100 and the tensioning assembly 200 to the anchor foundation.

[0053] In this embodiment, see Figure 3The first end of the first tension member 210 is provided with a hanging part 215, and the mooring cable 400 is provided with a connecting ring 410. The connecting ring 410 is hung on the hanging part 215 to realize the connection between the mooring cable 400 and the first tension member 210.

[0054] For example, the mounting part 215 includes a mounting post, and the connecting ring 410 is fitted onto the mounting post.

[0055] Example 2 like Figures 1 to 4 As shown, this embodiment provides a mooring system, including multiple floating platform mooring devices 20 of Embodiment 1. The floating platform 10 includes multiple corners, and the multiple floating platform mooring devices 20 are respectively arranged at the multiple corners of the floating platform 10.

[0056] The mooring system provided in this embodiment can reliably position and constrain the floating platform 10 in a specific sea area, effectively control the drift and twisting of the floating platform 10, and improve the stability of the equipment carried on the floating platform 10.

[0057] For example, the floating platform 10 has a rectangular cross-sectional shape and includes four corners. The mooring system of this embodiment includes four floating platform mooring devices 20.

[0058] In this embodiment, see Figure 1 and Figure 4 The floating platform 10 includes multiple floating units 11, which are arranged in a matrix and are movably connected to each other to reduce the stress between adjacent floating units 11 and improve the reliability of the floating platform 10.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
