Description

Technical Field

[0001] This application relates to the field of underwater platform construction technology, and in particular to underwater modular underwater balance pontoon. Background Technology

[0002] As marine engineering expands into deep-sea areas, floating wind power has become a key technology for developing deep-sea wind energy resources. Among these technologies, semi-submersible foundations are highly favored due to their relatively mature technology. To reduce reliance on large dry docks and lifting equipment, and to minimize costly offshore operations and risks, onshore assembly technology has emerged. This technology involves dividing a large semi-submersible platform into several modules, constructing them separately on shore, and then transporting them to a designated location at sea for overall docking.

[0003] However, a fundamental prerequisite for the successful implementation of existing water-based assembly technology is that each module can float completely horizontally on the water surface. Each module is typically regular in shape, has a uniform mass distribution, and can precisely adjust its draft and attitude using its own ballast system to achieve horizontal floating.

[0004] For certain floating structures, such as the four-post semi-submersible platforms used in some floating wind power projects, some of the disassembled sub-modules are irregularly shaped and have uneven mass distribution. Especially when some smaller modules are unloaded into the water, their irregular shapes and off-center centers of gravity immediately cause them to tilt or become unstable, making it impossible to maintain the required level position. This fundamental problem prevents subsequent precise wet towing and docking, severely limiting the application of modular floating docking technology on such irregular, unballasted platforms. Existing technologies typically rely on large lifting equipment or modifying modules to add permanent ballast systems, but this significantly increases costs and operational complexity. Utility Model Content

[0005] Based on this, an underwater module with underwater buoyancy is provided to solve the problem that irregular underwater modules cannot maintain horizontal floating independently.

[0006] Embodiments of this application propose an underwater modular underwater balancing pontoon, comprising:

[0007] A support frame for connecting to the underwater module;

[0008] A buoyancy mechanism, used to provide additional buoyancy, is disposed on the supporting frame;

[0009] A buoyancy adjustment mechanism, connected to the buoyancy mechanism, is used to adjust the additional buoyancy of the buoyancy mechanism so that the underwater module remains horizontally floating.

[0010] In one embodiment, the support frame is detachably connected to the underwater module.

[0011] In one embodiment, the underwater module's underwater balance float also includes a detachable connection mechanism, which includes multiple detachable flanges and detachable bolts. The detachable flanges are pre-installed at multiple locations on the underwater module and on the support frame, and the detachable bolts connect the detachable flanges.

[0012] In one embodiment, the buoyancy mechanism includes a plurality of inflatable air bladders;

[0013] The buoyancy adjustment mechanism adjusts the additional buoyancy by inflating or deflating the inflatable airbag.

[0014] In one embodiment, the buoyancy adjustment mechanism includes:

[0015] Gas source;

[0016] A pipeline connecting the air source and the inflatable airbag, and a valve is provided on the pipeline;

[0019] Several rods; and

[0020] A plurality of splicing connectors, wherein the splicing connectors are used to detachably connect two of the rods;

[0021] The rods and connectors are arranged to form several placement cavities, which are used to place the buoyancy mechanism.

[0022] In one embodiment, the splicing connector includes a plurality of splicing flanges and splicing bolts, the splicing flanges being disposed on the rod, and the splicing bolts connecting the splicing flanges.

[0023] In one embodiment, the underwater module's underwater balance float also includes a fixing member, through which the buoyancy mechanism is fixed to the support frame.

[0024] In one embodiment, the fastener includes a strap.

[0025] In one embodiment, multiple straps are provided, and the multiple straps are cross-shaped and fixed to the support frame.

[0026] According to the underwater module buoyancy tank of this application embodiment, the supporting frame is firmly connected to the target underwater module on one hand, and supports and fixes the buoyancy mechanism on the other hand, providing an installation foundation for the entire device. The buoyancy mechanism is installed on the supporting frame and, through its own buoyancy, provides additional upward lifting force to the underwater module, counteracting the sinking or tilting tendency caused by the module's irregular shape and center of gravity shift. The buoyancy adjustment mechanism can actively adjust the magnitude of the additional buoyancy generated by the buoyancy mechanism, and through dynamic adjustment, counteract the center of gravity shift of the underwater module, ultimately allowing the module to remain stably floating horizontally. The underwater module leveling does not rely on its own ballast system or external lifting equipment; horizontal floating can be achieved solely through the underwater module buoyancy tank, reducing reliance on large equipment and special facilities and reducing operating costs.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0058] See Figure 1 , Figure 2 and Figure 3 At least one embodiment of this application provides an underwater module underwater balance float 100, which includes a support frame 110, a buoyancy mechanism 120 and a buoyancy adjustment mechanism 130. The support frame 110 is used to connect with the underwater module 200; the buoyancy mechanism 120 is used to provide additional buoyancy and is disposed on the support frame 110; the buoyancy adjustment mechanism 130 is connected to the buoyancy mechanism 120 and is used to adjust the additional buoyancy of the buoyancy mechanism 120 so that the underwater module 200 remains horizontally floating.

[0059] According to the embodiment of this application, the underwater module buoy 100 has a supporting frame 110 that is firmly connected to the target underwater module 200 and supports and fixes the buoyancy mechanism 120, providing an installation foundation for the entire device. The buoyancy mechanism 120 is mounted on the supporting frame 110 and, through its own buoyancy, provides additional upward lifting force to the underwater module 200, counteracting the sinking or tilting tendency caused by the module's irregular shape and center of gravity shift. The buoyancy adjustment mechanism 130 can actively adjust the magnitude of the additional buoyancy generated by the buoyancy mechanism 120. Through dynamic adjustment, it counteracts the center of gravity shift of the underwater module 200, ultimately allowing the module to maintain stable horizontal floating. The leveling of the underwater module 200 does not rely on its own ballast system or external lifting equipment; horizontal floating can be achieved solely through the underwater module buoy 100, reducing reliance on large equipment and special facilities, reducing operating costs, and solving the problem that irregular underwater modules 200 cannot maintain horizontal floating autonomously.

[0060] See Figure 2 and Figure 4In some embodiments, the support frame 110 is detachably connected to the underwater module 200, flexibly adapting to different scenarios and the underwater module 200. Specifically, the underwater balance float 100 of the underwater module also includes a detachable connection mechanism 140, which includes multiple detachable flanges 141 and detachable bolts 142. The detachable flanges 141 are pre-installed at multiple positions on the underwater module 200 and on the support frame 110, respectively, and the detachable bolts 142 connect the detachable flanges 141. When it is necessary to provide balancing buoyancy to a certain underwater module 200, the support frame 110 can be connected to the module; after the module completes horizontal floating, transfer, or closure, the support frame 110 can be disassembled and reused for other modules, improving equipment utilization.

[0061] See Figure 3 and Figure 4 In some embodiments, the buoyancy mechanism 120 includes a plurality of inflatable airbags 121; the buoyancy adjustment mechanism 130 adjusts the additional buoyancy by inflating or deflating the inflatable airbags 121. Specifically, the inflatable airbags 121 are provided with inflation ports 122, through which gas is inflated and deflated.

[0062] In some embodiments, the buoyancy adjustment mechanism 130 includes an air source 131, a pipeline 132, and a control module 133. The pipeline 132 connects the air source 131 to the inflatable airbag 121. A valve 1321 is installed on the pipeline 132. The control module 133 is communicatively connected to the valve 1321 and adjusts the additional buoyancy by controlling the valve 1321. Specifically, the air source 131 can be configured as an air compressor. When the underwater module 200 tilts, the control module 133 receives a tilt signal, which may be a command input after manual observation or automatic detection by a sensor. The control module 133 sends a command to the valve 1321 of the corresponding pipeline 132 according to the tilt situation. When the module is adjusted to a horizontal state, the control module 133 sends a closing command to the valve 1321, the air stops flowing in and out, the buoyancy of the inflatable airbag 121 remains stable, and the underwater module 200 remains horizontal. The buoyancy adjustment mechanism 130 enables precise adjustment of buoyancy, which can quickly counteract the shift of the module's center of gravity, allowing the module to reach and maintain a horizontal state with high leveling accuracy and fast response speed.

[0063] See Figure 4 , Figure 5 and Figure 6In some embodiments, the supporting frame 110 is configured as a truss structure, which includes a plurality of rods 111 and a plurality of splicing connectors 112. The splicing connectors 112 are used to detachably connect two rods 111. The plurality of rods 111 and splicing connectors 112 enclose a plurality of placement cavities 101, which are used to place the buoyancy mechanism 120. The underwater module's underwater balance float 100 adopts a detachable splicing truss structure. The specifications of the rods 111 and the size of the inflatable airbags 121 can be flexibly adjusted to adapt to irregular underwater modules 200 of different sizes and shapes.

[0064] In some embodiments, the pipe fittings may be selected as steel pipes. In addition to steel pipes, the rods 111 may also be made of lightweight and high-strength materials such as aluminum alloy pipes and fiberglass reinforced plastic pipes, which are suitable for scenarios with strict requirements on the self-weight of the pontoon. In addition to disassembling the flanges 141 and disassembling the bolts 142, the splicing connectors 112 may also adopt quick snaps, pin connections and other methods to improve the splicing efficiency of the load-bearing frame 110, which are suitable for emergency operations or frequent disassembly and assembly scenarios.

[0065] In some embodiments, the splicing connector 112 includes a plurality of splicing flanges 1121 and splicing bolts 1122. The splicing flanges 1121 are disposed on the rods 111, and the splicing bolts 1122 connect the splicing flanges 1121. Specifically, before production or assembly, the splicing flanges 1121 are first fixed to the ends of each rod 111. When it is necessary to connect two rods 111, the flange faces of the first rod 111 and the flange faces of the second rod 111 are precisely fitted together to ensure that the holes on the two flanges are completely aligned and the splicing bolts 1122 can pass through smoothly. The splicing bolts 1122 are passed through the two aligned flange holes, and then the nuts are tightened at the other end of the splicing bolts 1122. Through the tightening force of the splicing bolts 1122, the two splicing flanges 1121 are pressed tightly together, and finally a stable connection of the two rods 111 is achieved. When it is necessary to adjust the size of the load-bearing frame 110 or disassemble the frame, simply unscrew the bolts to separate the two rods 111. Both the splicing flange 1121 and the rods 111 can be reused to adapt to different scenarios.

[0066] See Figure 7 In some embodiments, the underwater module's underwater balance float 100 further includes a fixing member 150, and the buoyancy mechanism 120 is fixed to the support frame 110 via the fixing member 150; the fixing member 150 includes straps. The firm connection between the support frame 110 and the underwater module 200 and the stable fixation of the inflatable airbag 121 ensure the stability of the module during the floating and transfer process, providing a guarantee for precise closure.

[0067] In some embodiments, multiple straps are provided, and the multiple straps are cross-shaped and fixed to the support frame 110. Specifically, a set of straps is first wrapped laterally along the support frame 110, crossing the inflatable airbag 121 and the frame rod 111; then another set of straps is wrapped longitudinally, forming an intersection with the first set of straps, and finally forming a cross-shaped constraint structure in the placement cavity 101. The intersection point must be aligned with the center area of ​​the inflatable airbag 121 to ensure that the constraint force of the straps is evenly applied to the surface of the inflatable airbag 121, avoiding excessive local stress that could cause deformation of the inflatable airbag 121; both ends of the straps must be firmly fixed to the rod 111 of the support frame 110, and the tightness of the straps can be adjusted by means of buckle locking, bolt tightening, etc., so that the inflatable airbag 121 fits tightly against the inner wall of the placement cavity 101 without any loose gaps. Furthermore, if the inflatable airbag 121 is large in size, multiple sets of straps can be added to the cross-shaped structure, such as in a star shape, to further enhance the fixing strength and cope with extreme situations such as strong water flow and module tilting.

[0068] Compared to single-direction strap fixation, the cross-shaped layout creates three-dimensional constraints in both the horizontal and vertical dimensions. This prevents the inflatable airbag 121 from sliding along the frame members 111 under water flow impact, and also prevents the inflatable airbag 121 from shifting up and down due to changes in buoyancy or module tilt. This ensures that the buoyancy mechanism 120 remains in the preset placement cavity 101 position, guaranteeing precise buoyancy application. The cross-shaped straps evenly distribute the weight, buoyancy, and water flow impact force of the inflatable airbag 121 across multiple members 111 of the supporting frame 110, preventing concentrated tension on certain straps that could damage the inflatable airbag 121. It also reduces the load on individual straps, improving the overall durability of the fixing structure.

[0069] The underwater module buoy 100 provided in this application uses pipe fittings of corresponding specifications selected according to the size, shape and center of gravity of the irregular module. The pipe fittings are assembled on-site to form a load-bearing frame through splicing connectors 112. The load-bearing frame 110 is fixedly connected to the underwater module 200. The inflatable airbag 121 is installed inside the load-bearing frame through fasteners 150 and connected to the buoyancy adjustment mechanism 130. The buoyancy adjustment mechanism 130 inflates the inflatable airbag 121. According to the horizontal state of the underwater module 200, the amount of gas in the inflatable airbag 121 is adjusted. The buoyancy generated by the inflatable airbag 121 is used to counteract the center of gravity shift of the module, so that the underwater module 200 gradually reaches a horizontal floating state. If the underwater module 200 tilts, the buoyancy distribution is adjusted by inflating or deflating the corresponding side inflatable airbag 121 to maintain the horizontal state of the underwater module 200.

[0070] See Figure 8 At least one embodiment of this application proposes a method for balancing and closing on water, which includes the following steps:

[0071] Step S100: Divide the irregular underwater platform into multiple underwater modules 200;

[0072] In step S200, the transport carrier 300 transports multiple underwater modules 200 to the preset closure sea area;

[0073] In step S300, the transport carrier 300 sinks, causing the underwater module 200 to detach from the transport carrier 300.

[0074] Step S400: Transfer all underwater modules 200 to the merging carrier 500;

[0075] Step S500: Complete the underwater assembly of the underwater module 200.

[0076] The procedure further includes the following steps before transferring all underwater modules 200 to the assembly carrier 500 and / or before completing the underwater assembly of the underwater modules 200, i.e. before step S400 and / or step S500:

[0077] The underwater module buoy 100 in any of the above embodiments is connected to a portion of the underwater module 200, and the buoyancy adjustment mechanism 130 adjusts the additional buoyancy of the buoyancy mechanism 120 so that the underwater module 200 remains horizontally floating.

[0078] Specifically, before transferring all the underwater modules 200 to the merging carrier 500, i.e. before step S400, the underwater modules 200 have just detached from the transport carrier 300 and have not yet begun to be transferred to the merging carrier 500. The purpose of inserting the pontoon and leveling the module is to first adjust the underwater modules 200 to a horizontal floating state through the pontoon before wet towing, so as to avoid uneven traction force and water flow impact affecting the attitude due to the tilt of the underwater modules 200 during the transfer process, and to ensure a smooth transfer process.

[0079] Before the underwater modules 200 are assembled on the water, i.e., before step S500, some or all of the underwater modules 200 have been transferred to the assembly carrier 500, but the splicing and assembly between the underwater modules 200 has not yet been completed. The purpose of inserting the auxiliary box and leveling the module is to recalibrate the horizontal attitude of the underwater modules 200 before splicing, to avoid tilting of the underwater modules 200 due to slight offsets during the transfer process, and to ensure that the splicing surfaces of different underwater modules 200 are accurately aligned, thus providing conditions for subsequent assembly.

[0080] The waterborne assembly and balancing method according to the embodiments of this application addresses the issue of loading and transportation efficiency by focusing on five core aspects: disassembly, transportation, floating and leveling, and transfer and assembly of irregular modules. Compared with overall transport, the modular floating transport of the module 200 in the water allows for the loading of more cargo per voyage, resulting in greater cost savings on ocean voyages. It also solves the problem of unloading modules in the water, which previously required wet towing from the transport carrier 300 to the assembly carrier 500 in a horizontal state. In cases where the ballast of the module 200 itself cannot be adjusted in the water, there is no need to rely on cranes or other equipment to ensure the module's horizontal position. The waterborne assembly and balancing method provided in this application offers a new approach for wet towing and assembly of irregularly shaped floating platforms in the future.

[0081] See Figure 9 , Figure 10 and Figure 11 In some embodiments, the irregular underwater platform is configured as a four-column floating semi-submersible wind power platform. This platform is divided into a first module 210 and a second module 220. The second module 220 is an irregular module, and a water balance buoy 100 of the underwater module is connected to it. The first module 210 includes three columns and can maintain its underwater balance by adjusting its own ballast water for wet towing. Due to its irregular shape and high center of gravity, the second module 220 maintains its balance by adding auxiliary buoyancy to the water balance buoy 100 for wet towing. The modular transportation of the four-column floating semi-submersible wind power platform, along with its on-water assembly scheme, can save significant shipping costs.

[0082] Specifically, in some embodiments, a method for achieving balancing on water includes:

[0083] The transport vehicle 300 is configured as a semi-submersible vessel. Two semi-submersible vessels transport the first module 210 and the second module 220 of the four-pillar floating wind power semi-submersible platform to the preset closure sea area, respectively.

[0084] The semi-submersible vessel then sank, and the first module 210 was adjusted to a horizontal ballast level and towed away from the semi-submersible vessel. For the second module 220, an underwater module buoy 100 was installed to increase its buoyancy and resolve the eccentricity issue, ultimately allowing the second module 220 to float horizontally and be towed away from the semi-submersible vessel.

[0085] See Figure 11 In some embodiments, a method for balancing and merging on water also includes providing a temporary support structure 600, which is detachably mounted on the underwater module 200, such as the first module 210 and / or the second module 220, to enhance the rigidity of the first module 210 and / or the second module 220. This is particularly important for the irregularly shaped second module 220 of the four-column floating semi-submersible wind power platform, ensuring its structural stability during transportation and merging.

[0086] In some embodiments, step S400, transferring all underwater modules 200 to the merging carrier 500, specifically includes:

[0087] Connect the underwater module's underwater balance float 100 to a portion of the underwater module 200;

[0088] The underwater module 200 is transferred from the transport carrier 300 to the assembling carrier 500 using a wet towing device 400, during which the underwater module 200 remains horizontally floating.

[0089] With the above setup, the underwater module 200 always floats in the water, not lifted off the surface, but partially or fully submerged, with its bottom in contact with or close to the water surface, relying on buoyancy to support its own weight. Utilizing the buoyancy of the underwater module 200 and the traction force of the wet towing device 400, the module moves by floating on the water surface, from the position of the transport carrier 300 to the designated area of ​​the merging carrier.

[0090] See Figure 11 and Figure 12 In some embodiments, the assembly carrier 500 is configured as a semi-submersible barge or a semi-submersible transport vessel. The semi-submersible barge can achieve a semi-submersible state by adjusting its ballast water, with most of the hull submerged and the deck near the water surface. This allows the transferred underwater modules 200 to float smoothly onto the deck. Ballast adjustment then raises the hull, lifting the modules off the water and securing them for subsequent assembly. The semi-submersible transport vessel also has a semi-submersible adjustment function, and with a large deck area and strong load-bearing capacity, it can simultaneously accommodate multiple disassembled underwater modules 200. After transfer, assembly can be performed directly on the vessel, reducing the need for secondary module transfers and improving operational efficiency.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
