Technical Field

[0001] The present application relates to the field of marine engineering technology, and in particular to a quadrilateral floating platform. Background Art

[0002] As a crucial marine engineering facility, floating platforms play a vital role in offshore oil extraction, wind power generation, and other fields. Traditional floating platforms, due to their ruggedness and durability, provide reliable buoyancy and stability, ensuring the safety and efficiency of offshore operations.

[0003] The construction of existing floating platforms mainly focuses on the following aspects: first, optimizing the design by improving the platform structure to reduce the amount of steel used, thereby reducing costs; second, using advanced construction technology and equipment, such as large crane ships and self-elevating platforms, to improve construction efficiency and safety.

[0004] However, existing floating platforms, due to their large size and complex construction processes, require large cranes to transport them both onshore and offshore, increasing transportation difficulty and costs. Therefore, improving the transportability of floating platforms has become a key issue that needs to be addressed. Utility Model Content

[0005] In order to address the deficiencies in the prior art, the present application provides a quadrilateral structured floating platform that facilitates the transportation of transport equipment both on shore and on sea.

[0006] This application provides a quadrilateral floating platform adopting the following technical solutions:

[0007] A quadrilateral floating platform includes a floating platform, which includes a first floating body module, a second floating body module, and a third floating body module. The two ends of the first floating body module are fixedly connected to the second floating body module and the third floating body module through bending modules. A first buoy is provided on the top of the floating platform, and the floating platform is provided with a pulling body. The pulling body and the floating platform are fixedly connected to form a quadrilateral structure.

[0008] By adopting the above technical solution, before being dropped into the sea, the first floating module, the second floating module, the third floating module and the bending module can be transported separately, and then the basic construction, assembly, debugging and installation of the wind turbine can be carried out at the dock. There is no need to pre-assemble them into a huge whole before transportation. After assembly, the interior is hollow. When the transportation equipment is able to tow the towing body, water can flow freely through the hollow part, reducing the resistance of the water flow to the floating platform. The hydrodynamic performance is good, and it is convenient for the floating platform to be deployed in the predetermined sea area.

[0009] The present application further provides: the pulling body includes a second pontoon, and two second pontoons are provided, one second pontoon is provided at the top of one end of the second pontoon module away from the bending module, and the other second pontoon is provided at the top of one end of the third pontoon module away from the bending module, the first pontoon is provided at the center of the top of the first pontoon module, and a crossbeam is provided between the tops of the two second pontoons.

[0010] By adopting the above technical solution, the transportation equipment can be fixed to the crossbeam on the sea surface using a pulling component, and the crossbeam can be pulled to drag the floating platform to move on the sea surface, and the contact area with the water is reduced, so that the water resistance of the transportation equipment during pulling is reduced, making it easier to transport.

[0011] The present application further provides that: a reinforcement piece is provided between the two ends of the cross beam and the top of each second buoy, and the reinforcement piece, the cross beam and a second buoy form a triangular structure.

[0012] By adopting the above technical solution, the connection strength between the beam and the second pontoon is enhanced, and the stress dispersion range of the transport equipment when towing the beam is expanded, thereby minimizing the risk of the beam breaking due to stress concentration.

[0013] The present application further provides that: the first floating module, the second floating module and the third floating module are spliced ​​together from several floating module units, and the two ends of the bending module are fixedly connected to the first floating module, the second floating module and the third floating module close to one end of the bending module.

[0014] By adopting the above technical solution, the specifications of the floating module units are small, which is convenient for transportation on shore, and the same floating module units can be freely spliced ​​into floating platforms of any size.

[0015] The present application further provides: the pulling body includes a fourth float module, the two ends of the fourth float module are fixedly connected to the second float module and one end of the third float module away from the first float module through a bending module, and there are three first floats, two of which are arranged at the top of the bending modules at both ends of the fourth float module, and one first float is arranged at the center of the top of the first float module.

[0016] By adopting the above technical solution, when pulling the center of the fourth floating module having two first pontoons on the top, more gravity can be provided to help stabilize the pulling part, and the first pontoon in the center of the first floating module can stabilize the center of gravity of the center of the first floating module, reducing the risk of capsizing due to pulling.

[0017] The present application further provides that: the fourth floating body module is formed by splicing together a plurality of floating body module units, and both ends of the fourth floating body module are fixedly connected to an end of the bending module close to the fourth floating body module.

[0018] By adopting the above technical solution, the floating module unit has a smaller specification, which is convenient for transportation on shore, and the fourth floating module and the floating platform use the same floating module unit, which simplifies the manufacturing process and can be freely spliced.

[0019] The present application further provides that: the outer bending part of the bending module is set to be a rounded corner.

[0020] By adopting the above technical solution, when the floating platform is towed at sea, the rounded corners can guide the water flow more smoothly, reduce the resistance of the water flow to the structure, and thus reduce the force required for towing.

[0021] The present application further provides that: the bending part of the outer side of the bending module is set to a plane, and the angle formed between the plane and the outer side of the first floating module, the second floating module, the third floating module and the fourth floating module is an obtuse angle.

[0022] By adopting the above technical solution, the bending module with a flat surface at the bend can distribute the impact force when it is hit at the bend, and the obtuse-angled surface helps to smooth the water flow, reduce eddy currents, and lower hydrodynamic resistance.

[0023] The present application further provides that: the floating platform and the bending module can be made of solid buoyancy materials and / or metal materials according to actual needs.

[0024] By adopting the above technical solution, different solid buoyancy materials and / or metal materials are selected to make the floating platform and bending modules according to the actual environment, construction and other requirements, which can adapt to different usage scenarios.

[0025] The present application is further configured to include a submarine anchor chain, one end of which is fixedly connected to the floating platform, and the other end of which is fixedly connected to the seabed.

[0026] By adopting the above technical solution, the submarine anchor chain can fix the floating platform and the seabed, and try to avoid the displacement of the floating platform caused by natural forces such as wind and waves.

[0027] In summary, this application has the following beneficial effects:

[0028] When the present application is transported on shore, the first floating module, the second floating module, the third floating module and the bending module can be transported separately. After arriving at the dock on the coast, the floating platform can be constructed, assembled, debugged, and the wind turbine installed. There is no need to assemble them into a huge whole for transportation in advance. When transported on the sea, they are towed by traction equipment. The interior of the quadrilateral formed by the first floating module, the second floating module, the third floating module and the bending module is hollow, which facilitates the deployment of the floating platform in the predetermined sea area.

DETAILED DESCRIPTION

[0035] The following is combined with Figures 1 to 5 This application is described in further detail.

[0036] Example 1:

[0037] refer to Figure 1 and Figure 2 A quadrilateral floating platform includes a floating platform 1, a first pontoon 2 and a pulling body 4. The floating platform 1 includes a first floating module 11, a second floating module 12 and a third floating module 13. The two ends of the first floating module 11 are fixedly connected to the second floating module 12 and the third floating module 13 through a bending module 14.

[0038] The first buoy 2 is fixedly connected to the top of the floating platform 1. The fan 3 is inserted into the first buoy 2, which floats in the water and can maintain a balanced state to overcome the shaking effect of sea water on the foundation of the fan 3.

[0039] In this embodiment, the total length of the first floating module 11 and the bending modules 14 fixedly connected at both ends is 115m, the total length of the second floating module 12 and the bending modules 14 fixedly connected thereto, and the total length of the third floating module 13 and the bending modules 14 fixedly connected thereto are both 95m.

[0040] Before being put into the sea, the first floating module 11, the second floating module 12, the third floating module 13 and the bending module 14 can be transported to the shore separately to facilitate transportation of transportation equipment. The floating platform can be constructed, assembled, debugged and the wind turbine installed on land before being put into the sea, without the need to pre-assemble them into a huge whole.

[0041] In this embodiment, the height of the first buoy 2 is 30 m, which can reduce the possibility of waves splashing onto the wind turbine 3 .

[0042] The floating platform 1 is fixedly connected to the pulling body 4. The fixed connection between the pulling body 4 and the floating platform 1 forms a quadrilateral structure. The pulling body 4 and the floating platform 1 are the four sides of the quadrilateral structure. The interior of the quadrilateral structure is hollow. When the transportation equipment tows the pulling body 4, the water flow can freely pass through the hollow part, reducing the resistance of the water flow to the floating platform 1. The hydrodynamic performance is good, which facilitates the deployment of the floating platform 1 in the predetermined sea area.

[0043] Furthermore, the pulling body 4 includes a second pontoon 41, and two second pontoons 41 are provided. One second pontoon 41 is fixedly connected to the top of the end of the second pontoon module 12 away from the bending module 14, and the other second pontoon 41 is fixedly connected to the top of the end of the third pontoon module 13 away from the bending module 14. The first pontoon 2 is fixedly connected to the top center of the first pontoon module 11, and a crossbeam 42 is fixedly connected between the tops of the two second pontoons 41. The transportation equipment can be fixed on the crossbeam 42 using a pulling assembly on the sea surface. The crossbeam 42 is pulled to drag the floating platform 1 to move on the sea surface, and the contact area with the water is reduced, so that the transportation equipment is subjected to less water resistance when being pulled, which helps to resist the longitudinal and lateral swaying and tilting caused by environmental factors such as waves and wind, enhances the stability of the overall structure, and is more convenient for transportation.

[0044] Furthermore, a reinforcement 43 is fixedly connected between the two ends of the beam 42 and the top of each second pontoon 41. The reinforcement 43, the beam 42 and a second pontoon 41 form a triangular structure. The triangle is stable. The reinforcement 43 can enhance the connection strength between the beam 42 and the second pontoon 41, and also expand the stress dispersion range of the transportation equipment when pulling the beam 42, reducing the risk of the beam 42 breaking due to stress concentration.

[0045] In addition, in this embodiment, the first floating module 11, the second floating module 12, and the third floating module 13 are formed by splicing together a plurality of floating module units. Preferably, the first floating module 11, the second floating module 12, and the third floating module 13 are formed by fixing the plurality of floating module units at the node couplings at both ends with steel strands. Each floating module unit is 13 meters long, 10 meters wide, and 6.5 meters high. The floating module units are relatively small, making them convenient for onshore transportation. The bending module 14 is fixedly connected at both ends to the first floating module 11, the second floating module 12, and the third floating module 13 near the bending module 14. Preferably, the node couplings at both ends of the bending module 14 are fixedly connected to the node couplings at the first floating module 11, the second floating module 12, and the third floating module 13 near the bending module 14 by steel strands.

[0046] In addition, in addition to being connected by steel strands, a circle of flanges is also pre-buried between the two ends of the floating modules. The floating modules are connected by welding between the flanges.

[0047] In addition, the bending part on the outside of the bending module 14 is set to a rounded corner. Therefore, when the floating platform 1 is towed on the sea, the rounded corner on the outside of the bending module 14 can guide the water flow more smoothly, reduce the resistance of the water flow to the floating platform 1, thereby reducing the force required by the transportation equipment when towing the floating platform 1, and making it easier for the transportation equipment to transport the floating platform 1 at sea level.

[0048] In this embodiment, the first floating module 11, the second floating module 12, the third floating module 13 and the bending module 14 can be made of solid buoyancy materials and / or metal materials according to actual needs. Specifically, they can be cast with UHPC performance concrete. The UHPC material components do not contain coarse aggregates, and the particle size is generally less than 1MM. Due to its high density, it has strength and durability. The compressive strength can reach more than 200MPA, and the material durability can reach more than 200 years. In addition, because the fine steel fibers dispersed in UHPC can greatly slow down the expansion of microcracks inside the material, the material exhibits excellent toughness and ductility, can withstand extreme loads and stresses in the marine environment, and can effectively resist the penetration of chloride ions, sulfate erosion and repeated freeze-thaw effects, thereby extending the service life of the concrete structure and improving the overall strength.

[0049] Furthermore, the arc-shaped sides of the first floating module 11 , the second floating module 12 and the third floating module 13 in the longitudinal direction reduce the resistance of the water flow to the first floating module 11 , the second floating module 12 and the third floating module 13 .

[0050] In addition, a quadrilateral floating platform also includes a submarine anchor chain, one end of which is fixedly connected to the floating platform 1, and the other end of which is fixedly connected to the seabed. After being pulled to a predetermined sea area, the submarine anchor chain can be fixed at one end to the seabed and at the other end to the floating platform 1, thereby reducing the displacement of the floating platform 1 caused by natural forces such as wind and waves.

[0051] The implementation principle of Example 1 of the present application is as follows: the first floating module 11, the second floating module 12, and the third floating module 13 can be spliced ​​on shore through several floating module units and fixedly connected to form a whole through steel strands, and then connected to the bending module 14 to achieve a structure that is easy to transport and assemble. At the same time, the wind turbine 3 can be inserted into the first buoy 2 on shore. The pulling body 4 and the floating platform 1 form a quadrilateral structure. The internal hollow design reduces water flow resistance and improves hydrodynamic performance. The floating platform 1 is made of UHPC high-performance concrete, which has high strength and durability and can resist erosion in the marine environment. The wind turbine 3 can be fixed by seabed anchor chains to reduce the displacement of the floating platform 1.

[0052] Example 2:

[0053] refer to Figures 3 to 5 , the difference between Example 2 and Example 1 in the present application lies in the setting method of the pulling body 4. In this embodiment, the pulling body 4 includes a fourth floating module 44, and the two ends of the fourth floating module 44 are fixedly connected to the second floating module 12 and the third floating module 13 at one end away from the first floating module 11 through the bending module 14. Three first pontoons 2 are provided, two first pontoons 2 are fixedly connected to the top of the bending modules 14 at both ends of the fourth floating module 44, and one first pontoon 2 is fixedly connected to the center of the top of the first floating module 11. When the fourth floating module 44 is towed by the transportation equipment, since the top of the bending modules 14 at both ends of the fourth floating module 44 have two first pontoons 2, more buoyancy can be provided to help stabilize the pulling part, and the first pontoon 2 of the first floating module 11 is located in the central part. The first pontoon 2 in the central part can stabilize the center of gravity of the center of the first floating module 11, and try to avoid overturning caused by the pulling of the transportation equipment.

[0054] Furthermore, the fourth float module 44 is formed by splicing together several float module units. Preferably, the fourth float module 44 is formed by fixing the several float module units together at the node couplings via steel strands. The node couplings at both ends of the fourth float module 44 are fixedly connected to the bending module 14 at one end near the fourth float module 44. Preferably, the node couplings at both ends of the fourth float module 44 are fixedly connected to the node couplings at the bending module 14 at one end near the fourth float module 44 via steel strands. The fourth float module 44 uses the same float module units as the first float module 11, the second float module 12, and the third float module 13, simplifying the manufacturing process. The smaller size of the float module units facilitates onshore transportation and splicing.

[0055] Furthermore, the bending part on the outside of the bending module 14 is set to a plane, and the angle formed between the plane and the outer side of the first floating module 11, the second floating module 12, the third floating module 13 and the fourth floating module 44 is an obtuse angle. In this embodiment, the obtuse angle formed by each plane and the outer side surface of each floating module is 135°. The plane of the bending module 14 can share the impact force when it is hit at the bending part, and when the transportation equipment pulls the fourth floating module 44 forward on the sea surface, the plane of the bending module 14 helps to smooth the water flow, reduce eddy currents and reduce hydrodynamic resistance.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
