[0048] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0049] See also Figure 1-Figure 7 , shows a modular floating foundation platform according to a preferred embodiment of the present invention, comprising:

[0050] a plurality of floating body modules 1; and

[0051] A plurality of connectors 2 are provided, each connector 2 being disposed between two adjacent floating modules 1 and connecting the two adjacent floating modules 1 together.

[0052] The modular floating basic platform of the present invention comprises a plurality of floating modules 1 and a plurality of connectors 2. Two adjacent floating modules 1 are connected together by the connectors 2 to form a modular floating basic platform. Since the structural standard of the floating module 1, that is, the shape and size of the floating module 1 are standardized, the standardized production and batch manufacturing of the floating module 1 can be realized, which can reduce the manufacturing cost, that is, effectively reduce the cost of the modular floating basic platform; secondly, the modular design of the floating module 1 can reduce the workload of on-site construction, reduce the construction cost and time; thirdly, since the floating module 1 is small in size, the smaller floating The module 1 can be transported to the installation site by ship or other means of transportation, and then quickly assembled through the pre-set connector 2, making the transportation and installation of the floating module 1 more convenient and reducing the complexity and risk during the transportation and installation process; in addition, the design of the modular floating foundation platform is more flexible, and the number and arrangement of the floating modules 1 can be adjusted according to specific needs to meet different engineering requirements. This flexibility is particularly important when dealing with different water depths, wind conditions and geological conditions, so that the modular floating foundation platform can adapt to different sea conditions and environmental conditions, and can improve the operating reliability and safety of the floating wind turbine.

[0053] In one embodiment, the cross-sectional shape of the floating module 1 can be any one of circular, square, elliptical and polygonal, wherein the elliptical streamlined design helps to reduce the resistance generated when water flows around the structure.

[0054] In one embodiment, the buoyancy module 1 is constructed of steel, high-strength concrete, lightweight concrete, fiber-reinforced polymer (FRP) concrete, or other composite materials to ensure buoyancy and durability. The use of FRP in key locations can enhance structural strength and durability, particularly under high loads and harsh environments.

[0055] See also Figure 3-Figure 4 , in one embodiment, the plurality of floating modules 1 each have a buoyancy compartment 11;

[0056] The modular floating foundation platform also includes:

[0057] Multiple buoyancy regulating devices 3, each of which is provided on a corresponding float module 1, and each of which is used to adjust the ballast of the corresponding buoyancy compartment 11;

[0058] Multiple monitoring sensors (not shown in the figure), each of which is provided on a corresponding floating module 1 and is used to monitor the working status and environmental conditions of the corresponding floating module 1;

[0059] The control system (not shown in the figure) is electrically connected to the buoyancy regulating device 3 and the monitoring sensor. The control system is used to control the opening and closing of the corresponding buoyancy regulating device 3 according to the feedback information of the monitoring sensor. In this way, when the monitoring sensor detects that the working status and environmental conditions of the corresponding floating module 1 do not meet the set requirements, the control system controls the buoyancy adjustment device 3 on the corresponding floating module 1 to open according to the feedback information of the monitoring sensor, and adds or reduces the fluid to the corresponding buoyancy tank 11 through the buoyancy adjustment device 3 (it can be understood that the fluid can be liquid or gas), thereby increasing or decreasing the ballast of the corresponding floating module 1, so that the multiple floating modules 1 maintain stability, thereby keeping the modular floating foundation platform in the optimal posture, reducing the inclination angle of the wind turbine 6 during operation, and making the wind turbine 6 operate more stably. In addition, the combined setting of the buoyancy tank 11, the buoyancy adjustment device 3, the monitoring sensor and the control system enables the modular floating foundation platform to cope with different ocean conditions. Whether it is waves, tides or wind load changes, the buoyancy can be adjusted in real time to ensure the stability of the modular floating foundation platform. This flexibility enables the modular floating foundation platform to maintain long-term safe and efficient operation in harsh offshore environments, and is suitable for the application of large-scale floating wind farms.

[0060] See also Figure 4 In one embodiment, in order to improve the buoyancy adjustment accuracy of each floating module 1, each floating module 1 has multiple buoyancy compartments 11, and the multiple buoyancy compartments 11 on each floating module 1 are arranged horizontally. Each buoyancy compartment 11 is provided with a buoyancy adjustment device 3, and each buoyancy compartment 11 is monitored by a monitoring sensor, so that each buoyancy compartment 11 can be monitored in real time through each monitoring sensor and each buoyancy compartment 11 can be ballast-adjusted through each buoyancy adjustment device 3.

[0061] See also Figure 1 and Figure 2 In one embodiment, multiple floating modules 1 are arranged in sequence along the vertical direction to form a floating module. The number of floating modules can be one or more. When the number of floating modules is multiple, the multiple floating modules are connected through multiple floating modules 1 arranged horizontally, and the multiple floating modules are arranged at intervals around the wind turbine 6.

[0062] It is understood that the buoyancy adjustment of the present invention is specifically implemented in the following manner:

[0063] The working status and environmental conditions of the float module 1 include the inclination angle, draft, and fluid pressure in the buoyancy compartment 11 of the float module 1, that is, the monitoring sensor monitors the inclination angle, draft, and fluid pressure in the buoyancy compartment 11 of the corresponding float module 1 in real time. The data collected by the monitoring sensor is transmitted wirelessly to the control system. The control system uses a data analysis algorithm to process and analyze the data monitored by the monitoring sensor, identify the working status and environmental changes of the float module 1, and analyze the real-time data to determine whether the buoyancy of each float module 1 needs to be adjusted. If adjustment is required, the buoyancy amount that needs to be adjusted is calculated, and it is determined which buoyancy compartments 11 should be filled with water (or inflated with air) or drained (or exhausted).

[0064] For example, when the wind and waves increase (such as a typhoon), the tilt angle of the modular floating foundation platform may exceed the tilt angle threshold of the structural stability (beyond the safety range). At this time, the buoyancy distribution is changed by adjusting the amount of water or air in the buoyancy tanks 11 in front and behind the float module 1 to reduce the tilt angle of the platform and maintain the balance of the platform. At this time, the control system sends an instruction to the buoyancy adjustment device 3 to fill water (or air) or drain water (or exhaust) to the designated buoyancy tank 11. The buoyancy adjustment device 3 injects or discharges fluid into or out of the buoyancy tank 11 to change the buoyancy distribution of the modular floating foundation platform. Among them, the operating speed and the amount of fluid injected or discharged of the buoyancy adjustment device 3 are precisely controlled by the control system, so that the buoyancy of the float module 1 is automatically adjusted by controlling the opening and closing of the buoyancy adjustment device 3.

[0065] Taking the example of adding or removing water from the buoyancy chamber 11, the buoyancy adjustment is calculated by calculating the difference between the net buoyancy experienced by the float module 1 and the required equilibrium buoyancy. Assuming the monitoring sensor detects an increase in the draft of the float module 1, causing the float module 1 to sink, the ballast water volume ΔV in the buoyancy chamber 11 needs to be reduced to allow the float module 1 to float upward. Based on Archimedes' principle of buoyancy, the required buoyancy adjustment ΔF and the volume of water to be removed ΔV can be calculated as:

[0066] ΔF=ρ w gΔV

[0067] Where ΔF is the buoyancy difference, ρ w is the density of water, g is the acceleration due to gravity, and ΔV is the volume change of water in the buoyancy chamber 11.

[0068] For example, if 5000N of buoyancy is required to float the floating module 1, calculate ΔV:

[0069]

[0070] That is, about 0.5 cubic meters of water needs to be discharged from the buoyancy chamber 11 to achieve the target buoyancy.

[0071] Similarly, the basic principle of regulating the inclination angle of the floating module 1 is to restore the floating module 1 to a horizontal or near-balanced state by adjusting the buoyancy of different areas of the floating module 1. For example, in the case where the modular floating base platform tilts forward and backward, the buoyancy distribution can be changed by adjusting the amount of water in the front and rear buoyancy tanks 11 of the modular floating base platform. For example, if the front end of the modular floating base platform sinks, water can be drained from the front buoyancy tanks 11 and water can be added to the rear buoyancy tanks 11 to restore the floating module 1 to balance. Adjust the required buoyancy ΔF tilt It can be calculated by the following formula:

[0072]

[0073] Wherein: W is the gravity of the floating module 1; L is the distance from the center of mass of the floating module 1 to the buoyancy chamber 11; GM is the metacentric height, that is, the distance between the center of gravity and the metacentric; θ is the inclination angle of the floating body.

[0074] According to the adjusted buoyancy ΔF tilt , the water volume ΔV that needs to be adjusted can be calculated tilt

[0075]

[0076] For example, the weight of the floating module 1 is W = 500000N; the distance from the center of mass of the floating module 1 to the front and rear buoyancy chambers 11 is L1 = L2 = 20m, that is, the distance between the front and rear buoyancy chambers 11 of the floating module 1 is equal, GM = 5m; the pitch angle of the floating module 1 is θ = 5° = 0.0873rad; the density of water is ρ w =1025kg / m 3 Assuming that the change in pitch angle causes the front end of the floating module 1 to sink, it is necessary to reduce the water volume in the front buoyancy compartment 11 of the floating module 1 and increase the water volume in the rear buoyancy compartment 11 to restore balance. Calculate the buoyancy difference that needs to be adjusted:

[0077]

[0078] That is, to correct a pitch angle of 5°, the buoyancy difference between the front and rear buoyancy chambers 11 needs to be adjusted to approximately 10,900 N. The required discharge or injection volume is calculated as:

[0079]

[0080] The operating speed of the pump body in the buoyancy adjustment device 3 will be adjusted according to the degree of deviation from the target. The control system will set a target draft or equilibrium position and adjust it according to design requirements or real-time working conditions. When the floating module 1 deviates from the target position, the pump body needs to work to adjust the posture of the modular floating foundation platform. For example, the greater the tilt angle of the modular floating foundation platform, the more urgent the need to correct the modular floating foundation platform, and the faster the operating speed of the pump body will be, so as to discharge or inject enough water as soon as possible to adjust the posture of the modular floating foundation platform and ensure that the modular floating foundation platform can be restored to stability in time.

[0081] During the buoyancy adjustment process, the monitoring sensor continuously monitors the movement state and floating state changes of the float module 1, and the control system adjusts the operating speed of the buoyancy adjustment device 3 in real time according to the feedback data to achieve fine buoyancy adjustment.

[0082] When the modular floating foundation reaches the desired draft and equilibrium state, the control system stops buoyancy adjustment operations to maintain the stability of the modular floating foundation. The combination of buoyancy adjustment device 3, monitoring sensors, and control system can automatically control the modular floating foundation to maintain an optimal posture, thereby reducing the tilt angle of wind turbine 6 during operation.

[0083] In addition, to prevent the modular floating foundation platform from becoming unstable due to damage or leakage of the buoyancy compartments 11, the buoyancy compartments 11 are designed with independent isolation functions. When water enters a buoyancy compartment 11, the control system automatically isolates the buoyancy compartment 11 and adjusts the buoyancy of the remaining buoyancy compartments 11 to maintain the stability of the modular floating foundation platform. This can be achieved in the following ways:

[0084] Method 1: The independent isolation function of the buoyancy compartment 11 relies on the independent sealing structure 5 of each buoyancy compartment 11. The adjacent buoyancy compartments 11 are separated by a waterproof bulkhead 12. That is, each buoyancy compartment 11 is isolated from other buoyancy compartments 11 by the waterproof bulkhead 12. The waterproof bulkhead 12 has a waterproof function, ensuring that even if water enters one buoyancy compartment 11, the water will not penetrate into other buoyancy compartments 11.

[0085] Method 2: The control system monitors the pressure in the buoyancy chamber 11 through the pressure sensor 4 to determine whether the buoyancy chamber 11 is abnormally flooded. For example, the modular floating foundation platform further includes:

[0086] Multiple pressure sensors 4, each pressure sensor 4 is provided on a corresponding float module 1, and the pressure sensor 4 is used to monitor the pressure in the buoyancy compartment 11 on the corresponding float module 1;

[0087] The control system is electrically connected to the pressure sensor 4 and is also used to control the opening and closing of the buoyancy adjustment devices 3 on the remaining float modules 1 based on feedback information from the pressure sensor 4. Thus, when a buoyancy compartment 11 abnormally intrudes water, the pressure within the buoyancy compartment 11 will change significantly. The pressure sensor 4 within the corresponding buoyancy compartment 11 detects the sudden pressure change within that buoyancy compartment 11. The control system receives the feedback information from the pressure sensor 4 and responds promptly based on the feedback information. After isolating the damaged buoyancy compartment 11, the control system automatically adjusts the buoyancy of the remaining buoyancy compartments 11. By increasing or decreasing the amount of water in the remaining buoyancy compartments 11, the control system balances the buoyancy distribution of the entire modular floating foundation platform to compensate for the buoyancy loss of the flooded compartments and ensure the stability of the float.

[0088] See also Figure 3 In one embodiment, the buoyancy regulating device 3 comprises:

[0089] a flow channel 31, a first end of the flow channel 31 being connected to the buoyancy chamber 11; and

[0090] a pump body (not shown), wherein the pump body outlet is connected to the second end of the flow channel 31, the pump body inlet is used to connect to the water supply device or the air supply device, and the pump body is electrically connected to the control system; and

[0091] Valve 32 is provided on flow channel 31. Valve 32 is used to control the opening and closing of flow channel 31. Valve 32 is electrically connected to a control system. Thus, when the amount of water in the buoyancy chamber 11 needs to be increased, the control system controls the pump body to open, allowing the liquid in the water supply device or the gas in the gas supply device to enter the corresponding buoyancy chamber 11 through flow channel 31 under the power provided by the pump body until the fluid in the buoyancy chamber 11 reaches the required amount. The control system then controls the pump body to close. When the amount of water in the buoyancy chamber 11 needs to be reduced, the control system controls the valve 32 to open, allowing the fluid in the buoyancy chamber 11 to be discharged to the outside through flow channel 31. When the fluid in the buoyancy chamber 11 reaches the required amount, the control system then controls the valve 32 to close. This structure is simple, practical, and low-cost.

[0092] It can be understood that the water supply device can be the ocean, and the air supply device can be the atmospheric environment.

[0093] See also Figure 5 In one embodiment, the connector 2 comprises:

[0094] A connecting flange 21 is provided at an end of the floating module 1 and is arranged around a center line of the floating module 1 in a first direction. The connecting flange 21 has a connecting hole;

[0095] Bolts 22, the heads of the bolts 22 abutting against the connection flange 21 of one of the two adjacent floating modules 1, and the stems of the bolts 22 sequentially passing through the connection holes on the connection flanges 21 of the two adjacent floating modules 1; and

[0096] Nut 23 is threadedly connected to the rod of bolt 22, and nut 23 abuts against the connection flange 21 of the other of the two adjacent floating modules 1. Bolts 22 allow for quick assembly, convenient construction, and improved connection efficiency of the floating modules 1. This connection method ensures a tight and secure connection of the floating modules 1, and allows for adjustment of connection strength according to varying sea conditions. Furthermore, this connection method facilitates assembly and disassembly, facilitating maintenance of each floating module 1 and reducing maintenance difficulty and cost.

[0097] See also Figure 5 In one embodiment, the modular floating foundation platform further comprises:

[0098] The sealing structure 5 is sandwiched between the two connecting flanges 21 between two adjacent floating modules 1 to seal the connection between the two adjacent floating modules 1, prevent seawater from entering the floating modules 1, and ensure the buoyancy and stability of the floating modules 1.

[0099] In one embodiment, the sealing structure 5 includes a sealing gasket, which is made of a corrosion-resistant and highly elastic material, such as chloroprene rubber (CR) or ethylene propylene diene monomer (EPDM), and the cross-section of the sealing gasket is "O"-shaped or "U"-shaped to enhance the sealing effect.

[0100] In one embodiment, the connecting flange 21 has a sealing groove, and the sealing groove and the sealing gasket are adapted to ensure that the sealing gasket is accurately positioned.

[0101] See also Figure 6 In other embodiments, when the float modules 1 are made of concrete, the connectors 2 include steel bars 24. Adjacent float modules 1 are connected using prestressed steel bars 24 grouting. Coaxially arranged steel bar 24 channels and grouting holes are reserved on the float modules 1. The grouting holes have a diameter larger than the steel bar 24 channels. Prestressed steel bars 24 are then arranged between two adjacent float modules 1. The prestressed steel bars 24 are passed through the steel bar 24 channels and secured at one end. The steel bars 24 are evenly arranged along the connection interface and passed through the steel bar 24 channels within the float modules 1. Prestressing equipment then applies prestress to the steel bars 24. Finally, grouting material is injected through the grouting holes, ensuring that the steel bar 24 channels are filled with grouting material. The grouting material is allowed to solidify, forming a strong connection. The grouting holes must be designed at the connection interface of the float modules 1 to ensure that the grouting material is fully filled and tightly bonded to the prestressed steel bars 24.

[0102] In one embodiment, the outer surface of the floating module 1 is provided with a drag-reducing coating (not shown in the figure) and an anti-fouling coating (not shown in the figure) to reduce the friction resistance of the floating module 1, extend the service life of the floating module 1, and thus extend the service life of the modular floating foundation.

Also, due to the structural standards of the floating module 1, the standardized production and batch manufacturing of the floating module 1 can be realized, which can reduce the manufacturing cost, that is, effectively reduce the cost of the modular floating foundation platform; secondly, the modular design of the floating module 1 can reduce the workload of on-site construction, reducing the construction cost and time; thirdly, since the floating module 1 is small in size, the smaller floating module 1 can be transported to the installation site by ship or other means of transportation, and then quickly assembled through the pre-set connector 2, making the transportation and installation of the floating module 1 more convenient, reducing the complexity and risk during the transportation and installation process; in addition, the design of the modular floating foundation platform is more flexible, and the number and arrangement of the floating modules 1 can be adjusted according to specific needs to meet different engineering requirements.
