Description

Technical Field

[0001] This invention relates to the field of marine floating body technology, and in particular to a marine floating body system and an adaptive adjustment method. Background Technology

[0002] Currently, with the increasing development and utilization of the ocean, the application of offshore floating body systems is becoming more and more widespread, such as offshore wind power platforms, marine ranches, and floating production storage and offloading vessels. These offshore floating bodies require reliable connection devices to ensure the stability and safety of the entire system, while also being able to adapt to the complex marine environmental conditions, such as the movement and deformation of the floating bodies caused by waves, currents, wind, and other factors.

[0003] Traditional offshore floating hulls mainly employ rigid connections or fixed-length flexible connections. While rigid connections provide high structural rigidity, they are prone to stress concentration at the connection points under dynamic forces such as waves, increasing the risk of structural fatigue damage and resulting in low safety for the floating hull system. On the other hand, fixed-length flexible connections are difficult to adapt to changes in the relative positions of the floating hulls. When sea conditions change, excessive tension or slack may occur, affecting the normal operation of the system and leading to poor safety for the floating hull system. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a marine floating body system and an adaptive adjustment method, aiming to improve the safety of the marine floating body system.

[0005] The technical solution adopted in this invention is: a marine floating body system, including a floating body unit, an adjustment mechanism, a connecting component, and a mooring component; There are at least two floating body units, which are arranged at circumferential intervals around the outer periphery of the adjustment mechanism; A connection area is formed between two adjacent floating body units, and a set of connecting components is configured in the connection area between two adjacent floating body units; a connecting plate is fixedly connected along the entire length of the side of the floating body unit closest to the connection area; The connecting assembly includes an adjustment cable. One end of the adjustment cable is connected to the adjustment mechanism and fixedly connected to the adjustment mechanism. The other end starts from the connecting plate at the edge of any one of the two adjacent float units, passes through the connecting plates respectively provided at the edges of the two float units in sequence, and then returns to the connecting plate of the starting float unit and is fixed. The adjustment mechanism changes the distance between two adjacent float units by scaling the adjustment cable. The adjustment mechanism and the bottom of each floating unit are respectively used to connect to the seabed via mooring components.

[0006] According to the above scheme, the adjustment mechanism includes a rotating body and a driving component; the driving end of the driving component is connected to the rotating body, driving the rotating body to rotate around its own axis; the rotating body is connected to one end of the adjustment cable.

[0007] According to the above scheme, the connecting plate has multiple cable-passing holes spaced apart along its length. The adjustment cable is sequentially passed through the cable-passing holes on the connecting plates of two adjacent float units, and one end of the adjustment cable is connected to the rotating body.

[0008] According to the above scheme, the mooring assembly includes mooring cables and mooring chains; wherein, multiple mooring cables are provided, with their upper ends respectively connected to the bottom of the floating body unit or the adjustment mechanism, and their lower ends connected to the mooring chains; the lower end of the mooring chains is connected to the mooring foundation laid on the seabed.

[0009] According to the above scheme, a guide is installed in the cable hole of the connecting plate.

[0010] According to the above scheme, the guide component is a roller.

[0011] According to the above scheme, the marine floating body system also includes a control component, which includes a sensor and a controller. The sensor is connected to the controller and is used to acquire environmental operating condition data and real-time status data of the floating body unit in real time, and send the data to the controller. The controller is connected to the drive component of the adjustment mechanism. The controller receives the data information sent by the sensor and controls the drive component to drive the rotating body to rotate according to the data information, thereby adjusting the distance between adjacent floating body units.

[0012] According to the above scheme, the sensor includes a tension sensor and a wave sensor. The tension sensor is used to detect the dynamic tension data of the regulating cable in real time; the wave sensor is used to detect the wave height of the ocean waves in real time.

[0013] This invention also discloses an adaptive adjustment method for a marine floating body system, the method being: When the sea is calm, or during equipment installation / maintenance, activate the tightening mode: The controller controls the driving component of the adjustment mechanism to drive the rotating body to rotate and wind up the adjustment cable. The adjustment cable is crisscrossed in the connecting plate, dragging adjacent float units closer to each other and reducing the distance between the float units. Under normal sea conditions, the controller automatically adjusts the regulating cable according to the range of wave height variation via the adjustment mechanism. When in rough seas, the relaxation mode is activated: the controller controls the drive components to rotate the rotating body in the opposite direction, releasing the adjustment cable to the preset maximum allowable length, so that the spacing between the floating body units reaches the design limit, forming a buffer space.

[0014] According to the above scheme, when the wave height is less than 0.1m, it is determined to be calm sea conditions and the tightening mode is activated; when the wave height is 0.1~3m, it is determined to be normal sea conditions and the normal mode is activated; when the wave height is more than 3m, it is determined to be giant wave sea conditions and the relaxation mode is activated.

[0015] The beneficial effects of this invention are as follows: 1. The spacing between floating body units directly affects their overall buoyancy distribution and wave response performance. This invention designs a connecting component and an adjustment mechanism. The connecting component connects two adjacent floating body units, and the adjustment mechanism adjusts the connecting component to adjust the spacing between adjacent floating body units. This adjustment method improves the overall stability and shock resistance of the system, effectively adapts to complex marine environmental conditions, and enhances the stability and safety of the marine floating body system. For example, when facing large waves, increasing the spacing between two adjacent floating body units allows the floating body units to increase their relative motion space within a controllable range, which is equivalent to providing a buffer for impact energy and reducing the overall wave resistance and overturning moment.

[0016] 2. The connecting components in this invention utilize adjustment cables, simplifying assembly and maintenance. Furthermore, the adjustment cables enable rapid fine-tuning of the float layout without disassembling the system, improving operational efficiency and reducing offshore maintenance costs.

[0017] 3. The present invention designs a mooring assembly, in which the adjustment mechanism and the floating body unit are fixed to the seabed by the mooring assembly, thereby maintaining positional stability in the overall structure, while allowing a certain degree of relative movement.

[0018] 4. This invention supports the connection of multiple floating units and can precisely control the layout relationship of adjacent units through the adjustment mechanism, which facilitates modular deployment and subsequent expansion. It has broad application prospects in marine engineering, offshore platforms, floating photovoltaics, power station pontoons and other fields. Attached Figure Description

[0028] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] like Figure 1 , 2 A marine floating body system, as shown in Figures 6 and 7, includes a floating body unit 1, an adjustment mechanism 3, a connecting assembly 2, and a mooring assembly 100. There are at least two floating body units 1, which are arranged at intervals around the outer periphery of the adjustment mechanism 3 along the circumferential direction; A connection area is formed between two adjacent floating body units 1, and a set of connecting components 2 is arranged in the connection area between two adjacent floating body units 1; a connecting plate 4 is fixedly connected along the entire length of the side of the floating body unit 1 closest to the connection area. The connecting component 2 includes an adjustment cable 21. One end of the adjustment cable 21 is connected to the adjustment mechanism 3 and fixedly connected to the adjustment mechanism 3. The other end starts from the connecting plate 4 on the side of any one of the two adjacent float units 1, passes through the connecting plates 4 respectively provided on the sides of the two float units 1 in sequence, and then returns to the connecting plate 4 of the starting float unit 1 and is fixed. The adjustment mechanism 3 changes the distance between two adjacent float units 1 by scaling the adjustment cable 21. The adjustment mechanism 3 and the bottom of each floating unit 1 are respectively used to connect to the seabed 200 through the mooring assembly 100 to achieve the overall system's marine positioning.

[0030] Preferably, the adjustment mechanism 3 includes a rotating body 31 and a driving member 32; the driving end of the driving member 32 is connected to the rotating body 31; the rotating body 31 is connected to one end of the adjustment cable 21; when the driving member 32 drives the rotating body 31 to rotate around its own axis, one end of the adjustment cable 21 is wound up or released with the rotation of the rotating body 31, and the length of the adjustment cable 21 changes accordingly, decreasing when wound up and increasing when released.

[0031] Preferably, such as Figures 2-5 As shown, the connecting plate 4 has multiple cable holes 41 spaced apart along its length. The adjusting cable 21 is sequentially passed through the cable holes 41 on the connecting plate 4 of two adjacent float units 1, and one end of the adjusting cable 21 is connected to the rotating body 31. The rotating body 31 is driven to rotate by the driving component 32, and the adjusting cable 21 is tightened and released synchronously with the rotation of the rotating body 31, thereby adjusting the distance between adjacent float units 1.

[0032] Specifically, the regulating cable 21 is threaded through the corresponding connecting plates 4 of two adjacent floating body units 1 to connect them. The length of the regulating cable 21 is adjusted by the regulating mechanism 3 through the retraction and extension actions, thereby controlling the spacing between the floating body units 1: the regulating mechanism 3 actively tightens the regulating cable 21, and the regulating cable 21 drags the adjacent floating body units 1 closer to each other, so that the spacing between them decreases synchronously; the regulating mechanism 3 releases the regulating cable 21 to reserve a length margin. Under the impact of the waves, the adjacent floating body units 1 generate relative movement and the regulating cable 21 gradually loosens. During this process, the relative distance between them increases synchronously with the degree of cable loosening, so as to achieve adaptive adjustment of the spacing.

[0033] Preferably, a guide is provided in the cable hole 41 of the connecting plate 4 to guide the sliding of the adjusting cable 21 and reduce friction. In this invention, the guide is a roller.

[0034] In this invention, the floating body unit 1 can be an offshore wind power platform unit, etc., which is a mature structure in the industry and is not the main improvement point of this application, so it will not be described in detail here.

[0035] Preferably, the mooring assembly 100 includes mooring cables 102 and mooring chains 101; wherein, multiple mooring cables 102 are provided, the upper ends of which are respectively connected to the bottom of the floating body unit 1 or the adjustment mechanism 3, and the lower ends are connected to the mooring chains 101; the lower end of the mooring chains 101 is respectively connected to the mooring foundation laid on the seabed 200, so as to realize the stable positioning of the floating body system and the seabed 200.

[0036] In this invention, the mooring assembly 100 adopts a common configuration in the field of marine engineering. Its specific structural selection and installation process are conventional technical means in this field and will not be described in detail here.

[0037] Preferably, the marine floating body system further includes a control component, which includes a sensor and a controller. The sensor is connected to the controller and is used to acquire environmental operating condition data and real-time status data of the floating body unit 1 in real time, and send the data to the controller. The controller is connected to the drive component 32 of the adjustment mechanism 3. The controller receives the data information sent by the sensor and controls the drive component 32 to drive the rotating body 31 to rotate according to the data information, thereby adjusting the spacing between adjacent floating body units 1.

[0038] In this invention, the sensor includes a tension sensor and a wave sensor, wherein the tension sensor is used to detect the dynamic tension data of the regulating cable 21 in real time; and the wave sensor is used to detect the wave height of the ocean waves in real time.

[0039] In this invention, the sensors also include a GPS positioning sensor and an attitude sensor. The GPS positioning sensor is used to collect the position information of the floating body unit 1 and the adjustment mechanism 3 and send the position information to the controller. The controller obtains the position information of the floating body unit 1 and calculates the distance between it and the adjustment mechanism 3. If the real-time position information of the floating body unit 1 is detected to deviate from the set range, the controller controls the adjustment mechanism 3 to adjust the length of the adjustment cable 21 until the distance between the floating body unit 1 and the adjustment mechanism 3 is within the set range. The attitude sensor can be a three-axis gyroscope, used to detect and obtain the real-time attitude angle of the floating body unit 1 in real time, reflecting the degree and direction of the floating body unit 1 deviating from the equilibrium state. If the real-time attitude angle data of the floating body unit 1 is detected to deviate from the set range, the controller adjusts it by controlling the damper in the floating body unit 1 (this is prior art and not the main improvement point of this application, so it will not be described in detail here) until the real-time attitude angle of the floating body unit 1 is within the set range.

[0040] In this invention, the attitude sensor, tension sensor, and wave sensor are all integrated into the float unit 1. The tension sensor is used to detect the tension of the regulating cable 21 and is installed at the connection between the regulating cable 21 and the connecting plate 4 or the regulating mechanism 3; GPS positioning sensors are installed in the float unit 1 and the regulating mechanism 3 respectively.

[0041] The sensor is used to collect the positioning information and real-time status information of the float. At the same time, the adjustment mechanism 3 integrates a GPS positioning sensor. Through algorithm analysis, it can determine whether the current array is in a preset safe, stable or working mode, and determine the relative position of the float unit 1 and the adjustment mechanism 3. Once it deviates from the set parameter range, the control component can quickly issue an adjustment command.

[0042] An adaptive adjustment method for a marine floating body system, specifically an adaptive adjustment method for the spacing of floating body units 1 in a marine floating body system, the method being as follows: When the sea is calm, or during equipment installation / maintenance, activate the tightening mode: The controller controls the drive unit 32 of the adjustment mechanism 3 to drive the rotating body 31 to rotate and wind up the adjustment cable 21. The adjustment cable 21 is crossed in the cable hole 41 of the connecting plate 4, directly dragging the adjacent float units 1 closer to each other, thereby reducing the distance between the float units 1 (the controller controls the adjustment cable 21 to be tightened to a set length, and judges whether the adjustment cable 21 is tightened according to the tension sensor), and improves the overall structural rigidity. Under normal sea conditions, the controller automatically adjusts the regulating cable 21 via the adjusting mechanism 3 according to the range of wave height variation. When in rough seas, the relaxation mode is activated: the controller controls the drive unit 32 to drive the rotating body 31 to rotate in the opposite direction, releasing the adjustment cable 21 to the preset maximum allowable length, so that the spacing between the floating body units 1 reaches the design limit, forming a buffer space.

[0043] In this invention, the wave sensor of the floating body unit 1 detects the wave height. When the detected wave height is less than 0.1m, it is determined to be a calm sea state, and the tightening mode is activated; when the detected wave height is 0.1~3m, it is determined to be a normal sea state, and the normal mode is activated; when the detected wave height exceeds 3m, it is determined to be a very rough sea state, and the loosening mode is activated. Simultaneously, equipment installation / maintenance needs to be carried out under high-rigidity conditions, therefore, the spacing of the floating body units 1 also needs to be tightened under these conditions.

[0044] In this invention, in the tightening mode, the controller controls the drive component 32 to drive the rotating body 31 to rotate and tighten the adjusting cable 21, reducing the spacing between the float units 1. (The controller controls the adjusting cable 21 to tighten to a set length and determines whether the adjusting cable 21 is taut based on the tension sensor.) At the same time, the tension sensor determines whether the adjusting cable 21 between the float units 1 is taut: the tension sensor collects the dynamic tension data of the adjusting cable 21 in real time and feeds it back to the controller. The controller presets a tension judgment threshold range based on the rated breaking force of the adjusting cable 21. The controller compares the real-time tension value collected by the tension sensor with the preset threshold range. If the real-time tension value falls into the judgment range, it is determined that the adjusting cable 21 is taut, and then instructs the drive component 32 to stop running, terminating the operation of reducing the spacing between the float units 1. If the real-time tension value does not reach the lower limit of the judgment threshold, the drive component 32 continues to run, continuing to reduce the spacing between the float units 1 until the tension value detected by the tension sensor reaches the standard.

[0045] In this invention, under normal sea conditions, the regulating cable 21 is automatically scaled according to the range of wave height variation. Specifically, when the sea conditions are in a preset normal range, the adjustment distance of the regulating mechanism 3 corresponds to a linear variation range: as the wave height increases, the length of the regulating cable 21 driven by the regulating mechanism 3 increases linearly until it reaches a preset maximum value. The linear variation range of this adjustment distance is bound to a preset tension threshold. The system determines whether the current adjustment distance is within the preset adjustment range by real-time detection of the matching relationship between the actual tension value of the regulating cable 21 and the preset tension threshold, thereby achieving control of the length of the regulating cable 21.

[0046] In this invention, the relaxation mode is activated under conditions of large waves. The control component releases the regulating cable 21 to its maximum permissible length. At this time, the spacing between the float units 1 is at its maximum, forming a buffer space to resist the impact of large waves. The maximum permissible length of the regulating cable 21 is designed according to actual conditions.

[0047] In this invention, the real-time state differences between each floating body unit 1 can be ignored. Compared with the marine environment, this floating body system can be simplified to a single point. Since the relative positions of the floating bodies are relatively consistent, the circumferential rotation of the rotating body 31 has a negligible impact on the attitude of the floating body system. The adjustment cable 21 has a perforated design, and there are specific trajectories to limit the displacement of the adjustment cable 21 when it is extended or retracted. At the same time, it is scaled in a coordinated manner when scaling, which avoids the tangling and knotting between the adjustment cables 21.

[0048] Example 1 like Figures 1-6 As shown, this embodiment designs a marine floating body system, which, in addition to the above-mentioned structure, also includes the following design: the marine floating body system includes four floating body units 1, and is configured with four connecting components 2.

[0049] In this embodiment, the adjustment mechanism 3 and the floating body unit 1 do not float on the water surface separately, but are each connected to the seabed 200 through the mooring assembly 100, so as to maintain a stable position in the overall structure, while allowing a certain degree of relative movement.

[0050] In this embodiment, multiple cable-passing holes 41 are evenly spaced along the length of the outer side of the connecting plate 4. Each float unit 1 is connected to its adjacent counterpart through the connecting components 2 on both sides. Therefore, a connecting plate 4 is provided on each of the two connecting areas of each float unit 1. The adjusting cable 21 passes through the cable-passing holes 41 of the connecting plates 4 of two adjacent float units 1 in sequence, and one end of it is connected back to the adjusting mechanism 3, thus realizing the flexible interconnection between the float units 1.

[0051] In this embodiment, each connecting plate 4 is fixed to the side of the float unit 1 facing the adjacent float unit 1, allowing the regulating cable 2121 to be laid across the float and form a reliable connection. This avoids the structural stress concentration problem that may be caused by the regulating cable 21 being directly fixed to the shell of the float unit 1, thus improving the overall mechanical performance and long-term service reliability of the device. The connecting plate 4 is provided with multiple cable-passing holes 41 arranged at intervals along the extension direction, allowing the regulating cable 21 to be sequentially and crosswise passed through two adjacent connecting plates 4 according to a predetermined path, forming a staggered anchoring structure cable laying method. On the one hand, this structure enhances the binding effect between the regulating cable 21 and the connecting plate 4, improving the overall impact resistance and connection stability; on the other hand, this crosswise passing method helps to distribute the load when the regulating cable 21 is under force, avoiding excessive force at a single point, and effectively mitigating the risk of damage to the regulating cable 21 due to fatigue or corrosion.

[0052] In this embodiment, four floating body units 1 are centrally symmetrically arranged around the outer periphery of the adjustment mechanism 3. This arrangement not only helps improve the overall structural balance and stability but also significantly enhances the system's anti-overturning capability and load distribution capability under complex sea conditions, thereby achieving attitude self-adaptation and structural coordination during the operation of the offshore floating body system. This structural arrangement also places the adjustment mechanism 3 in the geometric center region of the system, facilitating multi-directional balanced control of the tension in the connecting cables, enhancing the symmetry and precision of the adjustment response, and avoiding local instability or stress concentration at the connection points between floating bodies caused by uneven loads. This further extends the overall service life of the system and improves the reliability and safety of its operation at sea.

[0053] In this embodiment, there are eight connecting plates 4. These eight connecting plates 4 are fixed to the two sides of each of the four floating units 1 facing the two adjacent floating units 1. Each floating unit 1 is connected to its two adjacent floating units 1 via two connecting plates 4. By setting connecting plates 4 on both sides of each floating unit 1 and connecting them to the two adjacent floating units 1 via adjusting cables 21, a closed, interlocking connection structure is formed. Compared to a connection with only one connection point, this double-sided connection structure significantly improves the structural rigidity and connection reliability between the floating units 1, better resisting the impact of external forces such as sea waves, and enhancing the overall anti-disturbance capability of the floating device. Since the connecting plates 4 are located on two opposite sides of the floating unit 1, and the adjusting cables 21 are crisscrossed between multiple connection points, stress concentration at each connection point can be effectively dispersed, reducing the risk of fatigue damage to the connecting components and improving the durability and service life of the device. This method of connecting each floating unit 1 to the two adjacent floating units 1 on both sides facilitates modular installation and combination, allowing for flexible adjustment of the number and arrangement of floating units as needed in practical applications. Meanwhile, the reasonable distribution of connection points facilitates the maintenance and replacement of individual floating units 1 without dismantling the overall structure, thus improving the efficiency and convenience of later operation and maintenance.

[0054] In this embodiment, the two connecting plates 4 corresponding to each float unit 1 are manufactured using an integral molding process. By adopting an integral molding process, each float unit 1 and the two connecting plates 4 used to connect adjacent float units 1 are manufactured as a whole, avoiding the stress concentration problem at the connection points caused by welding or screwing in traditional splicing structures, thereby improving the overall strength and fatigue resistance of the connection structure. Integral molding also reduces assembly steps and manual operations in the manufacturing process, improving production efficiency and reducing manufacturing costs. Since the connecting plate 4 is an integral structure, the possibility of component misalignment is reduced during assembly, which is conducive to improving the installation accuracy and structural stability of the float device, further enhancing the reliability and service life of the entire device in complex marine environments.

[0055] In this embodiment, a guide is provided within the cable hole 41 of the connecting plate 4 to guide the sliding of the regulating cable 21 and reduce friction. By providing a guide within the cable hole 41 of the connecting plate 4 and using the guide to guide the sliding and positioning of the regulating cable 21, the guiding and sliding smoothness of the regulating cable 21 within the cable hole 41 can be effectively improved. On the one hand, the guide structurally limits and supports the regulating cable 21, keeping it stable and preventing it from swaying when passing between the connecting plates 4, which is beneficial to the stability of the system operation. On the other hand, the guide can be made of low-friction materials, such as nylon or polytetrafluoroethylene, thereby significantly reducing energy loss and cable wear caused by friction during the sliding of the regulating cable 21, extending the service life of the device. This is especially helpful in improving the overall system reliability and maintenance convenience in the harsh marine environment where the floating body system is exposed to moisture, corrosion, and violent shaking for extended periods.

[0056] Furthermore, the guide is a roller, which can provide rolling support when the adjusting cable 21 passes through the cable hole 41, thereby effectively reducing the frictional resistance between the adjusting cable 21 and the connecting plate 4, reducing cable wear, and improving adjustment efficiency and service life.

[0057] In this embodiment, the driving component 32 may be a motor. The rotating body 31 is disposed on the outer periphery of the driving component 32.

[0058] In this invention, the regulating cable 21 plays a crucial role in connecting and positioning the various float units 1. Changing the length of the regulating cable 21 directly alters the spacing between the float units 1, thereby controlling the structural form and mechanical response of the float array. Connecting one end of the regulating cable 21 to the rotating body 31 and rotating the rotating body 31 via the driving component 32 effectively creates a controllable cable winding and unwinding mechanism. The rotation direction and angle of the driving component 32 control the tightening or loosening length of the regulating cable 21, thus directly adjusting the spacing between adjacent float units 1.

[0059] In this embodiment, the controller determines whether the spacing between the floating body units 1 needs to be adjusted based on the collected data. When a change in operating conditions is detected, the controller sends a command to the drive unit 32, which rotates the rotating body 31 to wind up or release the adjustment cable 21, thereby reducing or expanding the spacing between the floating body units 11 to maintain the overall stability of the system and the shape control of the floating structure.

[0060] This embodiment designs a control component that enables the system to automatically adjust the relative positions of each floating body unit 1 in real time according to changes in operating conditions. This allows for intelligent deployment, dynamic adjustment, and precise control of the floating body system, effectively improving the stability, flexibility, and adaptability of the floating body array. It is particularly suitable for applications with complex sea conditions or diverse functions, such as marine monitoring platforms, floating solar power stations, and floating docks.

[0061] In this embodiment, the linkage between the control component and the drive component 32 enables the entire system to possess dynamic closed-loop control capabilities. For example, it can automatically loosen the cables to release the impact force when dealing with wave impacts, or automatically adjust the spacing of the floating body units 1 under the action of ocean currents to prevent the cables from breaking. These are all real-time responses and proactive adjustments. Compared with traditional passive adjustments or manual operations, this system significantly improves the automation and intelligence level of the floating body system. It can automatically change the array configuration according to environmental conditions or task requirements, and realize the rapid construction and switching of different functional areas, such as deformable floating platforms and retractable work areas.

[0062] In this embodiment, the regulating cable 21 is a steel cable, typically composed of multiple strands of steel wire twisted together. Its tensile strength can reach over 1000 MPa, and the breaking strength of a single steel cable can range from several tons to tens of tons depending on its diameter, far exceeding that of general flexible materials. The steel cable, as the regulating cable 21, is used to connect and adjust the spacing between adjacent floating body units 1. It can effectively bear the tension between floating body structures under complex sea conditions such as strong winds, waves, and high currents, and also has good safety redundancy, avoiding structural instability caused by fatigue fracture. Although the steel cable is a metallic material, its twisted structure gives it a certain degree of flexibility. It can adapt to the dynamic tensile stress caused by the up-and-down movement and swaying of the floating body on the sea surface, and can quickly respond to tightening or loosening operations when controlled by the drive component 32, thereby achieving precise floating body distance adjustment. The steel cable can be treated with anti-corrosion processes such as galvanizing, stainless steel, or plastic coating, possessing good marine corrosion resistance and suitable for long-term use in marine environments with salt spray, high humidity, and high UV radiation, reducing maintenance costs and extending system lifespan. The regulating cable 21 is used in conjunction with the tension sensor to achieve real-time monitoring of the tension and the stress state of the float during the adjustment process, thereby improving the automation control capability and safety management level of the entire platform. Especially in large-scale floating body arrays at sea, it can further achieve balanced load distribution adjustment.

[0063] This embodiment is composed of several floating body units 1. Each floating body unit 1 is connected to the others by an adjustment cable 21. One or both ends of the adjustment cable 21 are fixed to a rotating body 31 located on the floating body unit 1. The rotating body 31 is controlled to rotate by a drive unit 32, and the drive unit 32 receives remote or local control commands through a control component to loosen or tighten the adjustment cable 21.

[0064] In this embodiment, an adjustment cable 21 is installed and connects two adjacent float units 1. Combined with an adjustment mechanism 3, the length of the adjustment cable 21 can be scaled, thereby enabling controllable adjustment of the relative distance between the float units 1. This structure allows the device to flexibly change the layout of the floats according to different sea conditions, load changes, or functional requirements such as equipment installation and dynamic response adjustments, exhibiting good adaptability and engineering adjustability.

[0065] In this embodiment, the spacing between the floating body units 1 directly affects their overall buoyancy distribution and wave response performance. Adjusting the spacing between the floating body units 1 via the adjusting cable 21 allows for optimization of the hydrodynamic characteristics of the structure according to operating conditions, thereby improving the overall stability and shock resistance of the system. When a giant wave violently impacts the system, if the spacing between the floating body units 1 is too small, adjacent floating body units 1 will collide violently due to large relative displacement, leading to structural damage such as deformation and cracking, or failure of connecting parts. By loosening the extended adjusting cable 21 via the adjusting mechanism 3, when a giant wave impacts the device, the force on adjacent floating body units 1 can be increased by the loosened adjusting cable 21, allowing the floating body units 1 to increase their relative motion space within a controllable range, effectively providing a buffer for the impact energy. Furthermore, waves can pass more smoothly through the spacing between the floating body units 1, reducing the wave resistance and overturning moment experienced by the overall system.

[0066] In this embodiment, the adjustment cable 21 serves as a connecting element, replacing traditional rigid connectors or multi-component connection methods, simplifying assembly and maintenance operations. Simultaneously, the adjustment cable 21 enables rapid fine-tuning of the float layout without disassembling the system, improving operational efficiency and reducing offshore maintenance costs. This technical solution supports the connection of multiple float units 1, and the layout relationship between adjacent units can be controlled through the adjustment mechanism 3, facilitating modular deployment and subsequent expansion. It has broad application prospects in marine engineering, offshore platforms, floating photovoltaic systems, and power station pontoons.

[0067] The adaptive adjustment method in this invention solves the stress concentration problem of traditional rigid connections: when the spacing is too small, the relaxation mode can avoid deformation or connector failure caused by collisions of the floating unit 1; at the same time, the increased gap allows waves to pass through efficiently, reducing overall wave resistance and capsizing moment. The optimized spacing directly improves hydrodynamic performance, and by adjusting buoyancy distribution and wave response characteristics, system stability is enhanced, making it particularly suitable for typhoon-prone sea areas. In addition, the adjustment cable 21, as the core connecting element, combined with the integrally molded connecting plate 4, simplifies the assembly process—maintenance does not require disassembling the system; layout fine-tuning can be completed solely through the adjustment mechanism 3, significantly reducing offshore operation costs.

[0068] Example 2 The difference between this embodiment and Embodiment 1 is that the rotating body 31 can be a bearing rotor structure.

[0069] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
