Description

Technical Field

[0001] This invention relates to the field of wind turbine tower foundation technology, and particularly to an adaptive tower foundation for wind turbines. Background Technology

[0002] The installation sites for wind turbine generators often require favorable wind resource conditions, which forces many wind power projects to be built in areas with complex geological conditions. Among these, soft soil geological environments are one of the most challenging geological conditions encountered in wind power construction.

[0003] However, in soft soil geological conditions, the lack of solid rock layers as anchoring foundations makes traditional anchor foundation solutions ineffective. The low bearing capacity of soft soil layers necessitates a significant increase in the size of conventional gravity foundations to meet load-bearing requirements. This not only greatly increases project costs but may also create difficulties in construction and transportation due to the excessively large foundations. Furthermore, the high compressibility of soft soil layers easily leads to uneven foundation settlement, affecting the verticality and operational safety of wind turbine towers. Summary of the Invention

[0004] The main objective of this invention is to propose an adaptive foundation for wind turbine towers, aiming to solve the technical problems of insufficient bearing capacity and poor stability of wind turbine tower foundations under soft soil geological conditions.

[0005] To achieve the above objectives, the present invention proposes an adaptive foundation for wind turbine towers, comprising:

[0006] A connecting seat is embedded in a soft soil layer, and the tower of the wind turbine generator is installed on the connecting seat. The top of the connecting seat extends upward out of the surface of the soft soil layer to form an adaptive end.

[0007] An adaptive adjustment mechanism is provided, which is disposed outside the connecting seat;

[0008] A support structure is provided, which surrounds the connecting seat and is positioned between the adaptive adjustment mechanism and the connecting seat. The support structure is inclined upward from the connecting seat toward the adaptive adjustment mechanism. The bottom end of the support structure is connected to the adaptive end. The output end of the adaptive adjustment mechanism is connected to the top end of the support structure and is used to tension the top end of the support structure downward, so that the bottom end of the support structure supports the connecting seat in the soft soil layer.

[0009] In one embodiment, the support structure includes a support ring and a plurality of hinge structures. The support ring is sleeved outside the connecting seat. The support ring and the plurality of hinge structures are all disposed between the adaptive adjustment mechanism and the connecting seat. The plurality of hinge seats are spaced apart along the outer edge of the connecting seat on the support ring. Each hinge structure is inclined upward from the connecting seat toward the adaptive adjustment mechanism. The bottom end of each hinge structure is connected to the adaptive end. The output end of the adaptive adjustment mechanism is connected to the top end of each hinge structure and is used to tension the top end of the hinge structure downward, so that the bottom end of the hinge structure lifts the connecting seat into the soft soil layer.

[0010] In one embodiment, the hinge structure includes a hinge seat, a rotating shaft, and a support rod. The hinge seat is connected to the top of the support ring, the support rod extends radially along the support ring, the rotating shaft extends horizontally, the support rod is hinged to the hinge seat via the rotating shaft, the support rod is inclined upward from the connecting seat toward the adaptive adjustment mechanism, the bottom end of the support rod is hinged to the adaptive end, and the output end of the adaptive adjustment mechanism is hinged to the top end of the support rod.

[0011] In one embodiment, the distance between the top end of the support rod and the rotating shaft is D1, and the distance between the bottom end of the support rod and the rotating shaft is D2, where D1 > D2.

[0012] In one embodiment, the support structure further includes a plurality of first lugs and a plurality of first steel cables. The number of first lugs is the same as the number of first steel cables and they are arranged in a one-to-one correspondence. The plurality of first lugs are spaced apart and connected to the top of the support ring along the outer edge of the connecting seat. Each first lug is connected to the external soil through a corresponding first steel cable. Each first steel cable is used to tension the corresponding first lug, so that the support ring is supported on the soft soil layer.

[0013] In one embodiment, the adaptive adjustment mechanism includes a support ring and a plurality of drive mechanisms. The support ring is sleeved outside the support structure. The plurality of drive mechanisms are installed at intervals on the top of the support ring along the periphery of the wind turbine tower. The output ends of the plurality of drive mechanisms are connected to the top end of the support structure and are used to tension the top end of the support structure downward, so that the bottom end of the support structure lifts the connecting seat into the soft soil layer.

[0014] In one embodiment, the driving mechanism includes a connecting component and a driving member. The driving member is mounted on the top of the support ring, and the connecting component is sleeved on the top of the support structure. The output end of the driving member is connected to the connecting component and is used to drive the connecting component to move downward, thereby causing the top of the support structure to be tensioned downward, so that the bottom end of the support structure lifts the connecting seat into the soft soil layer.

[0015] In one embodiment, the connecting assembly includes a connecting cable and a connecting sleeve, one end of the connecting cable being connected to the output end of the drive component, and the other end of the connecting cable being connected to the connecting sleeve, which is fitted onto the top of the support structure.

[0016] In one embodiment, the adaptive adjustment mechanism further includes a plurality of second lugs and a plurality of second steel cables. The number of second lugs is the same as the number of second steel cables and they are arranged in a one-to-one correspondence. The plurality of second lugs are spaced apart and connected to the top of the support ring along the outer edge of the connecting seat. Each second lug is connected to the external soil through a corresponding second steel cable. Each second steel cable is used to tension the corresponding second lug, so that the support ring is supported on the soft soil layer.

[0017] In one embodiment, the connecting seat includes a steel sleeve and a plurality of vertical ribs. The steel sleeve is a hollow sleeve with an open top. The steel sleeve is embedded in the soft soil layer. The top end of the steel sleeve extends upward beyond the surface of the soft soil layer to form the adaptive end. The adaptive end has a plurality of connecting holes. The bottom end of the supporting structure is connected to the adaptive end through the plurality of connecting holes. The plurality of vertical ribs are spaced apart along the circumference of the wind turbine tower inside the steel sleeve. The wind turbine tower is installed on the plurality of vertical ribs through flanges.

[0018] The technical solution of this invention utilizes a structural arrangement where the supporting structure is tilted upwards from the connecting seat towards the adaptive adjustment mechanism. This allows the downward tension force applied by the adaptive adjustment mechanism to be converted into an upward lifting force at the bottom of the supporting structure. Since it avoids complex foundation treatment or a significant increase in foundation size, it effectively avoids the increased engineering costs and construction and transportation difficulties caused by excessively large foundations in soft soil layers, as is common with traditional gravity foundations. This maintains the economic efficiency and construction feasibility of the foundation structure, simplifies the foundation construction process under soft soil geological conditions, and reduces the requirements for construction technology. Furthermore, when dealing with long-term settlement or dynamic load changes in soft soil layers, frequent foundation reinforcement or modification is no longer necessary. The connecting seat can obtain adjustable lifting support through the active tensioning of the adaptive adjustment mechanism, reducing the risk of foundation failure due to soft soil layer deformation.

[0030] The installation sites for wind turbine generators often require favorable wind resource conditions, which forces many wind power projects to be built in areas with complex geological conditions. Among these, soft soil geological environments are one of the most challenging geological conditions encountered in wind power construction.

[0031] Soft soil refers to fine-grained soils with high natural water content, high compressibility, and low shear strength, mainly including silt, silty soil, and peat. These soil layers are characterized by high water content, large void ratio, high compressibility coefficient, low permeability coefficient, and high sensitivity, exhibiting unfavorable properties in engineering construction such as low bearing capacity, high compressibility, and poor stability.

[0032] In traditional wind turbine foundation design, when encountering hard rock strata, anchor foundations are typically used. This involves anchoring prestressed anchors deep into the rock strata, utilizing the high strength and stability of the rock to provide reliable support for the wind turbine tower. This foundation type offers advantages such as relatively simple construction, lower cost, and high load-bearing capacity, and has been widely used in rocky foundation conditions.

[0033] However, in soft soil geological conditions, the lack of solid rock layers as anchoring foundations makes traditional anchor foundation solutions ineffective. The low bearing capacity of soft soil layers necessitates a significant increase in the size of conventional gravity foundations to meet load-bearing requirements. This not only greatly increases project costs but may also create difficulties in construction and transportation due to the excessively large foundations. Furthermore, the high compressibility of soft soil layers easily leads to uneven foundation settlement, affecting the verticality and operational safety of wind turbine towers.

[0034] In existing technologies, the following solutions are mainly used for wind turbine foundations in soft soil layers:

[0035] First, there's the enlarged foundation scheme, which reduces soil stress by increasing the foundation's base area. However, this scheme requires a large amount of concrete and steel reinforcement, resulting in high costs, and even then, long-term stability is difficult to guarantee when the soft soil layer is thick. Second, there are deep foundation schemes, such as pile foundations, which transfer the load to deeper, better soil layers or bedrock through the piles. However, in cases of thick soft soil layers without a good bearing stratum, pile foundations are difficult to design and construct, and are costly. Third, there are foundation treatment schemes, which improve the engineering properties of soft soil layers through methods such as replacement, dynamic compaction, and chemical hardening. However, the treatment effect is often limited, and the depth and scope of treatment are restricted.

[0036] The aforementioned existing technical solutions all have certain limitations: high cost, complex construction, limited applicability, and a lack of proactive adaptation to soft soil deformation. Especially in geological conditions where the soft soil layer is thick and there is no good bearing layer, existing technologies struggle to provide an economical and effective solution. Furthermore, wind turbine generators generate complex dynamic loads during operation, including wind loads and turbine vibration loads. The transmission and dissipation mechanisms of these dynamic loads in soft soil layers are complex, and existing foundation designs often struggle to effectively address the impact of these dynamic effects on foundation stability. More importantly, the engineering properties of soft soil layers change over time and with varying environmental conditions, such as the continuous development of consolidation settlement, changes in groundwater levels, and cumulative deformation under cyclic loads. These changes all affect the long-term stability of the foundation. Most existing foundation designs are static, lacking the ability to proactively adapt to and adjust to these long-term changes, making it difficult to guarantee the safe and stable operation of wind turbine generators throughout their design life.

[0037] To address this technical problem, this invention proposes an adaptive foundation for the tower of a wind turbine generator set.

[0038] Please see Figures 1 to 4In one embodiment of the present invention, the adaptive foundation of the wind turbine tower includes a connecting seat 100, an adaptive adjustment mechanism 200, and a support structure 300. The connecting seat 100 is embedded in a soft soil layer, and the wind turbine tower is installed on the connecting seat 100. The top end of the connecting seat 100 extends upward beyond the surface of the soft soil layer to form an adaptive end 101. The adaptive adjustment mechanism 200 is arranged around the connecting seat 100. The support structure 300 is arranged around the connecting seat 100 and between the adaptive adjustment mechanism 200 and the connecting seat 100. The support structure 300 is inclined upward from the connecting seat 100 toward the adaptive adjustment mechanism 200. The bottom end of the support structure 300 is connected to the adaptive end 101. The output end of the adaptive adjustment mechanism 200 is connected to the top end of the support structure 300 and is used to tension the top end of the support structure 300 downward so that the bottom end of the support structure 300 lifts the connecting seat 100 into the soft soil layer.

[0039] Specifically, when the adaptive foundation of the wind turbine tower of this application operates under soft soil geological conditions, the connecting seat 100, as the main load-bearing component, is embedded in the soft soil layer and bears all the load from the wind turbine tower. To address the technical problem of insufficient bearing capacity in the soft soil layer, the top of the connecting seat 100 extends upwards beyond the surface of the soft soil layer to form an adaptive end 101. This adaptive end 101 provides both an installation platform for the tower and a bottom connection position for the support structure 300. The adaptive adjustment mechanism 200 surrounds the connecting seat 100, maintaining a radial distance from the connecting seat 100 to form a ring arrangement. The support structure 300 is located within the ring space between the adaptive adjustment mechanism 200 and the connecting seat 100, and is inclined upwards from the connecting seat 100 towards the adaptive adjustment mechanism 200, forming an inclined posture that is lower on the inside and higher on the outside.

[0040] More specifically, when the output end of the adaptive adjustment mechanism 200 applies a downward tension force to the top of the support structure 300, this downward tension force is transmitted along the inclination direction of the support structure 300. According to the principle of force decomposition, the downward tension force is decomposed at the bottom of the support structure 300 into an upward lifting force component and an inward horizontal force component. The upward lifting force component acts directly on the adaptive end 101 of the connecting seat 100, generating an upward lifting effect on the connecting seat 100. Since the support structures 300 surround the connecting seat 100 and are distributed circumferentially, the upward lifting forces generated at the bottom of each support structure 300 work together to form a uniform circumferential lifting effect on the connecting seat 100, enabling the connecting seat 100 to obtain an upward active support force in the soft soil layer, effectively counteracting the sinking tendency of the connecting seat 100 caused by bearing the tower load.

[0041] The adaptive foundation for the wind turbine tower of this application adopts an inclined arrangement of the support structure 300, which can effectively solve the technical problem of insufficient foundation bearing capacity under soft soil geological conditions. The upward inclination of the support structure 300 allows the downward tension force applied by the adaptive adjustment mechanism 200 to be converted into an upward lifting force at the bottom of the support structure 300. This lifting force directly acts on the connecting seat 100, compensating for the insufficient bearing capacity of the connecting seat 100 in soft soil. Compared with the traditional gravity foundation, which requires a significant increase in foundation size, this application achieves active support for the connecting seat 100 through the inclined arrangement of the support structure 300 and the active tensioning of the adaptive adjustment mechanism 200. This significantly improves the foundation bearing capacity without increasing the foundation bottom area, avoiding increased engineering costs and construction and transportation difficulties caused by an excessively large foundation.

[0042] Moreover, compared to other static foundation types, this application employs an adaptive adjustment mechanism 200 to adjust the downward tension of the top of the support structure 300, and the upward lifting force generated at the bottom of the support structure 300 can be dynamically adjusted according to actual working conditions. When the soft soil layer slowly settles due to long-term load or consolidation process, the adaptive adjustment mechanism 200 can increase the tension force on the support structure 300, correspondingly increasing the lifting force at the bottom of the support structure 300, actively compensating for the settlement of the connecting seat 100, and maintaining the stability of the connecting seat 100 position. This ensures the verticality and operational safety of the wind turbine tower in soft soil environments and avoids the risk of affecting the normal operation of the unit due to foundation settlement.

[0043] As an optional implementation, the support structure 300 is a frustoconical annular support body. The bottom inner edge of the annular support body is connected to the adaptive end 101, and the top outer edge is connected to the output end of the adaptive adjustment mechanism 200. The annular support body is arranged in a continuous upward inclination along the radial direction, forming a complete annular inclined support surface. When the adaptive adjustment mechanism 200 applies a downward tension force to the top outer edge of the annular support body, the tension force is uniformly transmitted along the inclined surface of the annular support body, generating a continuous and uniform upward lifting force at the bottom inner edge of the annular support body. This lifting force continuously acts on the entire periphery of the adaptive end 101 of the connecting seat 100, realizing continuous circumferential lifting support for the connecting seat 100 and improving the uniformity and continuity of the lifting force distribution.

[0044] As an alternative implementation, the support structure 300 includes multiple support rods 323, which are circumferentially spaced along the outer edge of the connecting seat 100. Each support rod 323 extends upwardly from the connecting seat 100 toward the adaptive adjustment mechanism 200. The bottom end of each support rod 323 is connected to the adaptive end 101, and the top end of each support rod 323 is connected to the output end of the adaptive adjustment mechanism 200. When the adaptive adjustment mechanism 200 applies a downward tension force to the top end of each support rod 323, each support rod 323 is subjected to pressure along its axial direction. This pressure is decomposed at the bottom end of each support rod 323 to generate an upward lifting force component. The upward lifting force components of multiple support rods 323 act together on the adaptive end 101 of the connecting seat 100, forming a multi-point lifting support. Compared with a continuous annular support, the discrete arrangement of multiple support rods 323 has the advantages of simple structure and convenient construction. At the same time, the number and arrangement angle of the support rods 323 can be adjusted according to specific engineering needs, providing flexible structural adaptability.

[0045] In the technical solution provided by this invention, the supporting structure 300 is arranged so that the downward tension force applied by the adaptive adjustment mechanism 200 can be converted into an upward lifting force at the bottom of the supporting structure 300 by means of an upward tilting arrangement of the connecting seat 100 towards the adaptive adjustment mechanism 200. Since this does not involve complex foundation treatment or a significant increase in foundation size, it effectively avoids the increased engineering costs and construction and transportation difficulties caused by excessively large foundations in soft soil layers, thus maintaining the economy and construction feasibility of the foundation structure. Furthermore, it simplifies the foundation construction process under soft soil geological conditions and reduces the requirements for construction technology. In addition, when it is necessary to cope with long-term settlement or dynamic load changes in soft soil layers, frequent foundation reinforcement or modification is no longer required. The connecting seat 100 can obtain adjustable lifting support through the active tensioning of the adaptive adjustment mechanism 200, reducing the risk of foundation failure due to soft soil layer deformation.

[0046] Please continue reading. Figure 2 In an embodiment of the present invention, the support structure 300 includes a support ring 310 and a plurality of hinge structures 320. The support ring 310 is sleeved outside the connecting seat 100. The support ring 310 and the plurality of hinge structures 320 are all disposed between the adaptive adjustment mechanism 200 and the connecting seat 100. The plurality of hinge seats 321 are spaced apart on the support ring 310 along the outer edge of the connecting seat 100. Each hinge structure 320 is inclined upward from the connecting seat 100 toward the adaptive adjustment mechanism 200. The bottom end of each hinge structure 320 is connected to the adaptive end 101. The output end of the adaptive adjustment mechanism 200 is connected to the top end of each hinge structure 320 and is used to tension the top end of the hinge structure 320 downward so that the bottom end of the hinge structure 320 lifts the connecting seat 100 into the soft soil layer.

[0047] Specifically, the connecting seat 100 is embedded in the soft soil layer, and the support ring 310 is sleeved around the connecting seat 100, maintaining a radial distance between the support ring 310 and the connecting seat 100. The support ring 310 is located in the annular space between the adaptive adjustment mechanism 200 and the connecting seat 100. The support ring 310 can be connected to the connecting seat 100 and the adaptive adjustment mechanism 200 through a hinge structure 320. Multiple hinge structures 320 are spaced apart on the support ring 310 along the outer edge of the connecting seat 100. The hinge structures 320 are hinged to the support ring 310, allowing the hinge structures 320 to be angularly adjusted relative to the support ring 310. Each hinge structure 320 is inclined upwards from the connecting seat 100 towards the adaptive adjustment mechanism 200, forming an inclined posture with a lower inner slope and a higher outer slope. The inclination angle of the hinge structure 320 can be adjusted according to the soft soil layer conditions and load requirements. The bottom end of each hinge structure 320 is connected to the adaptive end 101 of the connecting seat 100, achieving a reliable connection between the hinge structure 320 and the connecting seat 100. The output end of the adaptive adjustment mechanism 200 is connected to the top end of each hinge structure 320, enabling the adaptive adjustment mechanism 200 to apply a downward tension force to each hinge structure 320. Understandably, the wind turbine tower is mounted on the connecting seat 100, and the support ring 310 forms a stable triangular support structure with the connecting seat 100 and the adaptive adjustment mechanism 200 through multiple hinge structures 320. Each hinge structure 320 is connected to the adaptive end 101 of the connecting seat 100, meaning the bottom end of each hinge structure 320 is connected to the adaptive end 101, thereby achieving the supporting function of the support structure 300. This allows the adaptive adjustment mechanism 200 to provide support to the connecting seat 100 through the hinge structures 320, resulting in a reasonable and effective structural arrangement.

[0048] More specifically, when the output end of the adaptive adjustment mechanism 200 applies a downward tension force to the top of each hinge structure 320, this downward tension force is transmitted along the tilt direction of each hinge structure 320. Since the hinge structures 320 are arranged at an upward tilt, the downward tension force is decomposed at the bottom of each hinge structure 320 into an upward lifting force component and an inward horizontal force component. The upward lifting force component acts directly on the adaptive end 101 of the connecting seat 100, and the upward lifting forces generated at the bottom of multiple hinge structures 320 work together to form multi-point support for the connecting seat 100. The support ring 310 provides intermediate support and a positioning reference for the multiple hinge structures 320, enabling each hinge structure 320 to maintain a stable tilt angle and uniform spacing, avoiding structural instability or uneven stress that may occur due to individual arrangement.

[0049] This application achieves further optimization of the load-bearing capacity and stability of the support structure 300 through the coordinated arrangement of the support ring 310 and multiple hinged structures 320. The support ring 310, as an intermediate load-bearing component, connects multiple discrete hinged structures 320 into a unified support system, improving the overall stiffness and stability of the entire support structure 300. The spaced arrangement of the multiple hinged structures 320 allows the lifting force to be evenly distributed around the adaptive end 101 of the connecting seat 100, avoiding local stress concentration and improving the uniformity of the load-bearing capacity of the connecting seat 100 in the soft soil layer. The hinged connection between the hinged structure 320 and the support ring 310 allows the hinged structure 320 to undergo slight angle adjustments during stress, adapting to the deformation and settlement of the soft soil layer, maintaining an effective connection between the support structure 300, the connecting seat 100, and the adaptive adjustment mechanism 200, and improving the foundation system's adaptability to soft soil layer deformation.

[0050] Please continue reading. Figure 2 and Figure 3 In an embodiment of the present invention, the hinge structure 320 includes a hinge seat 321, a rotating shaft 322, and a support rod 323. The hinge seat 321 is connected to the top of the support ring 310. The support rod 323 extends radially along the support ring 310. The rotating shaft 322 extends horizontally. The support rod 323 is hinged to the hinge seat 321 through the rotating shaft 322. The support rod 323 is inclined upward from the connecting seat 100 toward the adaptive adjustment mechanism 200. The bottom end of the support rod 323 is hinged to the adaptive end 101. The output end of the adaptive adjustment mechanism 200 is hinged to the top end of the support rod 323.

[0051] Specifically, the support ring 310 is sleeved outside the connecting seat 100, and the hinge seat 321 is connected to the top of the support ring 310. The hinge seat 321 and the support ring 310 are reliably assembled through a fixed connection. The support rod 323 extends radially along the support ring 310, meaning its extension direction is consistent with the radial direction of the support ring 310. The support rod 323 extends from the inside to the outside of the support ring 310. The rotating shaft 322 extends horizontally, and its axis is parallel to the horizontal plane. The rotating shaft 322 is installed inside the hinge seat 321. The support rod 323 is hinged to the hinge seat 321 via the rotating shaft 322, and the support rod 323 and the hinge seat 321 are hinged together via the rotating shaft 322, allowing the support rod 323 to rotate around the axis of the rotating shaft 322. The support rod 323 is inclined upwards from the connecting seat 100 toward the adaptive adjustment mechanism 200, forming an inclined posture with the inside lower than the outside. The inclination angle of the support rod 323 can be adjusted by the hinged connection of the rotating shaft 322. Understandably, the connecting seat 100 is buried in soft soil, and the support ring 310 forms a support system with the connecting seat 100 and the adaptive adjustment mechanism 200 through multiple hinged structures 320. The hinged seat 321 is connected to the top of the support ring 310, meaning the hinged seat 321 is located above the support ring 310. The bottom end of the support rod 323 is hinged to the adaptive end 101 of the connecting seat 100, and the top end of the support rod 323 is hinged to the output end of the adaptive adjustment mechanism 200, thereby realizing the connection function of the hinged structure 320 so that the adaptive adjustment mechanism 200 can provide support to the connecting seat 100 through the support rod 323.

[0052] More specifically, the hinge seat 321 serves as the connecting component between the support rod 323 and the support ring 310, providing a stable installation foundation and rotation fulcrum for the support rod 323. The hinge seat 321 is connected to the top of the support ring 310, allowing the support rod 323 to extend from the upper part of the support ring 310 towards the connecting seat 100 and the adaptive adjustment mechanism 200, forming a reasonable force transmission path. The horizontal arrangement of the rotating shaft 322 allows the support rod 323 to rotate around the rotating shaft 322 in a vertical plane. The inclination angle of the support rod 323 can be dynamically adjusted according to the soft soil conditions, load requirements, and the adjustment needs of the adaptive adjustment mechanism 200. When the adaptive adjustment mechanism 200 applies a downward tension force to the top of the support rod 323, the support rod 323 experiences a tensile force along its axial direction. This tensile force is transmitted through the support rod 323 to its bottom end, generating an upward lifting force component at the bottom end of the support rod 323, which acts on the adaptive end 101 of the connecting seat 100.

[0053] The bottom end of the support rod 323 is hinged to the adaptive end 101. This hinged connection allows the support rod 323 to make slight angular adjustments relative to the connecting seat 100 during the application of force, accommodating the slight displacement and rotation of the connecting seat 100 in the soft soil layer. The top end of the support rod 323 is hinged to the output end of the adaptive adjustment mechanism 200. This hinged connection allows the adaptive adjustment mechanism 200 to apply an adjustable tension force to the support rod 323, while also allowing the support rod 323 to make minor angular adjustments under the tension force, maintaining an effective connection between the support rod 323 and the adaptive adjustment mechanism 200. The hinged connections at both ends of the support rod 323 form a complete hinged force transmission chain, enabling the support rod 323 to adapt to the dynamic adjustment process of the foundation system while maintaining the connection.

[0054] This application achieves flexible adjustment and stable force transmission of the hinge structure 320 through the coordinated arrangement of the hinge seat 321, the rotating shaft 322, and the support rod 323. The horizontal arrangement of the rotating shaft 322 provides a standard rotation axis for the support rod 323, enabling precise angle adjustment of the support rod 323 in the vertical plane and avoiding unstable rotation or jamming caused by the misalignment of the rotation axis. The fixed connection of the hinge seat 321 ensures the stability of the position of the rotating shaft 322, providing a reliable fulcrum for the rotation of the support rod 323. The radial extension of the support rod 323 along the support ring 310 ensures that the force direction of the support rod 323 is consistent with the radial direction of the support ring 310, which is beneficial for the uniform transmission of load and the full utilization of the overall rigidity of the support ring 310.

[0055] In an embodiment of the present invention, the distance between the top end of the support rod 323 and the rotating shaft 322 is D1, and the distance between the bottom end of the support rod 323 and the rotating shaft 322 is D2, where D1 > D2.

[0056] Specifically, when the adaptive adjustment mechanism 200 applies a downward tension force to the top of the support rod 323, this tension force generates a rotational torque on the support rod 323 with the pivot shaft 322 as the fulcrum. Since D1 > D2, the top of the support rod 323 has a larger lever arm relative to the pivot shaft 322, allowing the same tension force to generate a larger rotational torque acting on the support rod 323. This rotational torque drives the support rod 323 to rotate around the pivot shaft 322, and the bottom end of the support rod 323 generates an upward lifting force on the adaptive end 101 of the connecting seat 100 during rotation. The distance relationship D1 > D2 creates a lever amplification effect, allowing the tension force applied by the adaptive adjustment mechanism 200 to be converted into a larger lifting force acting on the connecting seat 100 through the lever action of the support rod 323, thereby improving the force transmission efficiency and lifting effect.

[0057] More specifically, the asymmetrical distribution of the support rods 323 also affects their stability and adjustment accuracy. The configuration of D1 > D2 causes the center of gravity of the support rods 323 to be located above the rotating shaft 322. Under its own weight, the support rods 323 tend to rotate downwards, a tendency consistent with the downward tension of the adaptive adjustment mechanism 200, which helps maintain a stable stress state. When the soft soil layer settles or deforms, the support rods 323 can respond quickly under the tension adjustment of the adaptive adjustment mechanism 200, adjusting their angle through the rotation of the rotating shaft 322, thus maintaining an effective connection with the connecting seat 100 and the adaptive adjustment mechanism 200.

[0058] Please continue reading. Figure 1 and Figure 3 In an embodiment of the present invention, the support structure 300 further includes a plurality of first lugs 330 and a plurality of first steel cables 340. The number of first lugs 330 is the same as the number of first steel cables 340 and they are arranged in a one-to-one correspondence. The plurality of first lugs 330 are connected at intervals to the top of the support ring 310 along the outer edge of the connecting seat 100. Each first lug 330 is connected to the external soil through a corresponding first steel cable 340. Each first steel cable 340 is used to tension the corresponding first lug 330 so that the support ring 310 is supported on the soft soil layer.

[0059] Specifically, the support ring 310 is sleeved on the outside of the connecting seat 100. Multiple first lugs 330 are spaced apart and connected to the top of the support ring 310 along the outer edge of the connecting seat 100. The first lugs 330 and the support ring 310 are fixedly assembled by welding or bolts. The number of first lugs 330 corresponds to the number of first steel cables 340, and each first lug 330 is connected to a corresponding first steel cable 340. Each first lug 330 is connected to the external soil via its corresponding first steel cable 340. One end of each first steel cable 340 is connected to a first lug 330, and the other end extends into the stable soil outside the soft soil layer and is anchored. Each first steel cable 340 is used to tension the corresponding first lug 330. When tensioned, the first steel cable 340 applies an upward pulling force to the first lug 330, which is transmitted to the support ring 310 through the first lug 330. Understandably, the connecting seat 100 is embedded in the soft soil layer. The support ring 310 forms a support system with the connecting seat 100 and the adaptive adjustment mechanism 200 through multiple hinge structures 320. The first lug 330 is installed on the top of the support ring 310, that is, the first lug 330 is located on the upper surface of the support ring 310. The multiple first lugs 330 are respectively connected to the corresponding first steel cables 340. Each first steel cable 340 extends to the external soil and is anchored, thereby realizing the auxiliary support function of the support structure 300, so that the first steel cables 340 lift the support ring 310 through the first lugs 330.

[0060] More specifically, when each of the first steel cables 340 is in a taut state, the first steel cable 340 applies an upward tension force to the corresponding first lug 330, which acts directly on the top of the support ring 310. Multiple first lugs 330 are spaced apart along the outer edge of the connecting seat 100, ensuring that the tension force of each first steel cable 340 is evenly distributed around the periphery of the support ring 310, forming a multi-point support for the support ring 310. The tension of the first steel cables 340 maintains a relatively stable height position of the support ring 310 in the soft soil layer, preventing excessive sinking of the support ring 310 due to its own weight or load. The supported state of the support ring 310 provides a stable intermediate support foundation for multiple hinge structures 320, enabling each hinge structure 320 to maintain a predetermined tilt angle and stress state, ensuring the effective support of the connecting seat 100 by the adaptive adjustment mechanism 200 through the hinge structures 320.

[0061] The connection between the first steel cable 340 and the external soil provides additional load-bearing support to the supporting structure 300. This support force originates from the stable soil outside the soft soil layer and does not depend on the bearing capacity of the soft soil layer itself. When the soft soil layer settles or deforms, the tension of the first steel cable 340 can limit the sinking of the support ring 310 and maintain the relative positional relationship between the support ring 310 and the connecting seat 100. The one-to-one correspondence between the first lug 330 and the first steel cable 340 ensures the uniform distribution and transmission of tension force, avoiding tilting of the support ring 310 or local stress concentration caused by uneven force distribution.

[0062] This application, through the coordinated arrangement of multiple first lugs 330 and multiple first steel cables 340, further enhances the load-bearing capacity and stability of the supporting structure 300. The external anchoring of the first steel cables 340 provides the supporting structure 300 with a support force source independent of the soft soil layer, effectively compensating for the insufficient bearing capacity of the soft soil layer. The spaced distribution of the multiple first lugs 330 ensures that the tension force of the first steel cables 340 is evenly applied to the supporting ring 310, avoiding structural deformation or damage caused by excessive local stress. The one-to-one correspondence between the first lugs 330 and the first steel cables 340 simplifies the transmission path of the tension force, improving the force transmission efficiency and the overall reliability of the system.

[0063] Compared to the scheme where the support structure 300 relies solely on the adaptive adjustment mechanism 200 for lifting force, the first lug 330 and the first steel cable 340 added in this application provide auxiliary lifting support for the support structure 300. Even if the adaptive adjustment mechanism 200 malfunctions or its adjustment capacity is insufficient, the first steel cable 340 can still maintain the basic lifting state of the support ring 310, improving the safety and reliability of the foundation system. Furthermore, compared to other complex auxiliary support devices, this application uses a simple combination of the first lug 330 and the first steel cable 340. The tension adjustment of the first steel cable 340 can be achieved through conventional steel cable tensioning equipment, without the need for complex control systems or power devices. While providing effective auxiliary support, it maintains the simplicity and economy of the structure, further enhancing the applicability and engineering practicality of the foundation system in soft soil environments.

[0064] Please continue reading. Figure 1 and Figure 3 In an embodiment of the present invention, the adaptive adjustment mechanism 200 includes a support ring 210 and a plurality of drive mechanisms 220. The support ring 210 is sleeved on the outside of the support structure 300. The plurality of drive mechanisms 220 are installed at intervals on the top of the support ring 210 along the periphery of the wind turbine tower. The output ends of the plurality of drive mechanisms 220 are connected to the top end of the support structure 300 and are used to tension the top end of the support structure 300 downward, so that the bottom end of the support structure 300 lifts the connecting seat 100 into the soft soil layer.

[0065] Specifically, the wind turbine tower is mounted on the connecting seat 100, and the support ring 210 is sleeved on the support structure 300, maintaining a radial distance between the support ring 210 and the support structure 300. Multiple drive mechanisms 220 are spaced apart at the top of the support ring 210 along the periphery of the wind turbine tower, and the drive mechanisms 220 are reliably assembled with the support ring 210 through a fixed connection. The drive mechanism 220 can be an actuator with adjustable output force, such as a hydraulic cylinder, pneumatic cylinder, or electric push rod. The output ends of the multiple drive mechanisms 220 are connected to the top of the support structure 300, and the connection between the output ends of the drive mechanisms 220 and the top of the support structure 300 is achieved through connectors. The drive mechanisms 220 are used to tension the top of the support structure 300 downwards; in the working state, the drive mechanisms 220 apply a downward tension force to the top of the support structure 300. Understandably, the connecting seat 100 is embedded in the soft soil layer, and the supporting structure 300 is connected to the connecting seat 100 through multiple hinged structures 320. The adaptive adjustment mechanism 200 applies an adjustment force to the supporting structure 300 through the support ring 210 and multiple drive mechanisms 220. The multiple drive mechanisms 220 are respectively connected to the top end of the supporting structure 300, and each drive mechanism 220 applies a downward tension force to the supporting structure 300, thereby realizing the adjustment function of the adaptive adjustment mechanism 200, so that the bottom end of the supporting structure 300 lifts the connecting seat 100 into the soft soil layer through the hinged structures 320.

[0066] More specifically, when multiple drive mechanisms 220 apply a downward tension force to the top of the support structure 300, this tension force is transmitted through the support structure 300 to each hinge structure 320. The support structure 300 includes a support ring 310 and multiple hinge structures 320, each hinge structure 320 being inclined upwards from the connecting seat 100 towards the adaptive adjustment mechanism 200, with its top end connected to the output end of the adaptive adjustment mechanism 200. The downward tension force of the drive mechanism 220 acts on the top of each hinge structure 320 and is transmitted along the inclination direction of each hinge structure 320 to its bottom end. Since the hinge structures 320 are arranged in an upward inclination, the downward tension force is decomposed at the bottom end of each hinge structure 320 into an upward lifting force component and an inward horizontal force component. The upward lifting force component acts directly on the connecting seat 100, providing support for the connecting seat 100.

[0067] The arrangement of the support ring 210 provides a unified installation foundation and positioning reference for multiple drive mechanisms 220, enabling each drive mechanism 220 to be evenly distributed around the support structure 300 and maintain a stable installation position. The spaced installation of multiple drive mechanisms 220 along the periphery of the tower ensures a uniform distribution of tension force, avoiding problems of excessive or uneven localized stress caused by concentrated arrangement of drive mechanisms 220. Each drive mechanism 220 can independently adjust its output force according to the deformation state of the soft soil layer and the settlement of the connecting seat 100, achieving differentiated tension adjustment of the support structure 300 and adapting to the uneven deformation characteristics of the soft soil layer.

[0068] The positional relationship between the support ring 210 and the tower allows the adaptive adjustment mechanism 200 to fully utilize the structural stiffness and stability of the tower. The support ring 210 obtains a stable support foundation through its connection with the tower. Multiple drive mechanisms 220 are installed on top of the support ring 210. The working state of the drive mechanisms 220 is not directly affected by the deformation of the soft soil layer, ensuring the stability and controllability of the output force of the drive mechanisms 220. The connection between the output end of the drive mechanism 220 and the top of the support structure 300 forms a complete force transmission path, enabling the adjustment force of the drive mechanism 220 to be effectively transmitted to the support structure 300 and ultimately act on the connecting seat 100.

[0069] This application achieves precise control and efficient adjustment of the adaptive adjustment mechanism 200 through the coordinated arrangement of the support ring 210 and multiple drive mechanisms 220. The annular structure of the support ring 210 provides continuous installation space for the multiple drive mechanisms 220, allowing them to be arranged around the entire circumference of the support structure 300, forming a comprehensive adjustment coverage. The independent control of the multiple drive mechanisms 220 allows the adaptive adjustment mechanism 200 to make differentiated adjustments according to the soil deformation in different directions, improving the accuracy and specificity of the adjustment. The distribution of the drive mechanisms 220 along the periphery of the tower utilizes the circular cross-sectional characteristics of the tower, ensuring that the adjustment force is applied evenly to the support structure 300, avoiding [missing information].

[0070] Please continue reading. Figure 1 and Figure 3 In an embodiment of the present invention, the driving mechanism 220 includes a connecting component 221 and a driving component 222. The driving component 222 is installed on the top of the support ring 210, and the connecting component 221 is sleeved on the top of the support structure 300. The output end of the driving component 222 is connected to the connecting component 221 and is used to drive the connecting component 221 to move downward, so as to drive the top of the support structure 300 to be tensioned downward, so that the bottom end of the support structure 300 lifts the connecting seat 100 into the soft soil layer.

[0071] Specifically, multiple drive mechanisms 220 are installed at intervals on the top of the support ring 210 along the periphery of the wind turbine tower. Drive components 222 are installed on the top of the support ring 210, and are fixedly assembled with the support ring 210 by bolts or welding. A connecting assembly 221 is sleeved on the top of the support structure 300. The inner diameter of the connecting assembly 221 matches the outer diameter of the support structure 300, and the connecting assembly 221 is connected to the top of the support structure 300 by sleeve. The output end of the drive component 222 is connected to the connecting assembly 221. The drive component 222 can be a hydraulic cylinder, pneumatic cylinder, or electric push rod, with its piston rod or push rod serving as the output end connected to the connecting assembly 221. The drive component 222 drives the connecting assembly 221 to move downwards. In operation, the drive component 222 pushes the connecting assembly 221 downwards along the axial direction of the support structure 300. Understandably, the adaptive adjustment mechanism 200 applies an adjustment force to the support structure 300 through the support ring 210 and multiple drive mechanisms 220. The drive component 222 is mounted on the support ring 210, and the connecting assembly 221 is connected to the top of the support structure 300. The drive component 222 applies tension to the support structure 300 through the connecting assembly 221. The downward movement of the connecting assembly 221 causes the top of the support structure 300 to be tensioned downward, thereby realizing the tension adjustment function of the drive mechanism 220, so that the bottom of the support structure 300 lifts the connecting seat 100 into the soft soil layer through the hinge structures 320.

[0072] More specifically, when the driving component 222 drives the connecting assembly 221 to move downward, the connecting assembly 221 applies a downward tension force to the top of the support structure 300. The support structure 300 includes a support ring 310 and multiple hinge structures 320. Each hinge structure 320 is hinged to the support ring 310 via a pivot 322, and the top of each hinge structure 320 is connected to the adaptive adjustment mechanism 200. The downward tension force of the connecting assembly 221 is transmitted to each hinge structure 320 through the support structure 300, causing each hinge structure 320 to be subjected to a tensile force along its axial direction. Since each hinge structure 320 is inclined upward from the connecting seat 100 toward the adaptive adjustment mechanism 200, the downward tension force is decomposed into an upward lifting force component at the bottom end of each hinge structure 320. This lifting force component directly acts on the adaptive end 101 of the connecting seat 100, thereby providing support for the connecting seat 100.

[0073] The sleeved connection of the connecting component 221 ensures that the output force of the driving component 222 is evenly distributed across the entire top section of the supporting structure 300, avoiding stress concentration or structural deformation caused by localized stress. The sleeved fit between the connecting component 221 and the supporting structure 300 allows the connecting component 221 to undergo axial displacement relative to the supporting structure 300 during tensioning, while maintaining a reliable connection between the two. The adjustable output characteristics of the driving component 222 allow the downward movement of the connecting component 221 and the tensioning force to be adjusted according to the deformation state of the soft soil layer and the support requirements of the connecting seat 100.

[0074] The driving component 222 is installed on top of the support ring 210. The working state of the driving component 222 is not directly affected by the deformation of the soft soil layer, ensuring the stability and controllability of the output force of the driving component 222. The connection between the output end of the driving component 222 and the connecting assembly 221 forms a clear force transmission path, allowing the thrust of the driving component 222 to be directly converted into the downward tension force of the connecting assembly 221. The connecting assembly 221, as the force transmission component between the driving component 222 and the support structure 300, undertakes the function of force transmission and distribution, ensuring that the output force of the driving component 222 can effectively act on the top of the support structure 300.

[0075] Please continue reading. Figure 1 and Figure 3 In an embodiment of the present invention, the connecting component 221 includes a connecting cable 223 and a connecting sleeve 224. One end of the connecting cable 223 is connected to the output end of the drive component 222, and the other end of the connecting cable 223 is connected to the connecting sleeve 224. The connecting sleeve 224 is fitted onto the top of the support structure 300.

[0076] Specifically, the driving component 222 is installed on the top of the support ring 210. One end of the connecting steel cable 223 is connected to the output end of the driving component 222, which can be a piston rod or a push rod. The connecting steel cable 223 is fixedly connected to the output end of the driving component 222 through a connector or clamp. The other end of the connecting steel cable 223 is connected to the connecting sleeve 224. The connecting steel cable 223 is firmly connected to the connecting sleeve 224 through crimping, welding, or threaded connection. The connecting sleeve 224 is fitted onto the top of the support structure 300. The inner diameter of the connecting sleeve 224 matches the outer diameter of the top of the support structure 300, and the connecting sleeve 224 covers the outer surface of the top of the support structure 300 by fitting. The connecting sleeve 224 and the support structure 300 can be fixedly assembled through friction fit, key connection, or threaded connection. Understandably, the drive mechanism 220 includes a connecting assembly 221 and a drive member 222. The connecting assembly 221 connects the drive member 222 to the support structure 300 via a combination of a connecting cable 223 and a connecting sleeve 224. The output end of the drive member 222 is connected to the connecting sleeve 224 via the connecting cable 223. The connecting cable 223, as a force transmission component, transmits the output force of the drive member 222 to the connecting sleeve 224. The connecting sleeve 224, as a force relay component, applies the transmitted force to the top of the support structure 300, thereby realizing the force transmission function of the connecting assembly 221, so that the drive member 222 applies a tension adjustment force to the support structure 300 through the connecting assembly 221.

[0077] More specifically, when the driving component 222 applies a downward pulling force to the connecting steel cable 223, the connecting steel cable 223 transmits this pulling force to the connecting sleeve 224, which then applies the pulling force to the top of the supporting structure 300. The connecting steel cable 223 has good tensile strength and flexibility, capable of withstanding the tension applied by the driving component 222 and maintaining stable force transmission performance. The flexibility of the connecting steel cable 223 allows for a certain degree of adaptability in the connection between the driving component 222 and the supporting structure 300. When the supporting structure 300 undergoes slight displacement or angle adjustment due to deformation of the soft soil layer, the connecting steel cable 223 can adapt to this deformation without generating excessive additional stress. The sleeve structure of the connecting sleeve 224 ensures that the tension force is evenly distributed around the periphery of the top of the supporting structure 300, avoiding stress concentration caused by localized force.

[0078] The connection between the connecting steel cable 223 and the output end of the drive component 222 provides a flexible force transmission method for the drive mechanism 220. The length of the connecting steel cable 223 can be adjusted according to the distance between the drive component 222 and the support structure 300 to adapt to different installation space requirements. The tensile properties of the connecting steel cable 223 enable the drive component 222 to apply a stable tension force to the support structure 300, while the connecting steel cable 223 itself will not undergo significant deformation or slack due to tension. The connection between the connecting sleeve 224 and the connecting steel cable 223 forms a reliable force transmission node. The annular structure of the connecting sleeve 224 can distribute the concentrated force transmitted by the connecting steel cable 223 to the entire top section of the support structure 300.

[0079] The connecting sleeve 224 is fitted onto the top of the support structure 300, and the fit between the connecting sleeve 224 and the support structure 300 ensures the effective transmission of tension force. The inner surface of the connecting sleeve 224 forms a tight fit with the outer surface of the top of the support structure 300. When the connecting sleeve 224 is subjected to a downward pulling force from the connecting cable 223, this force is transmitted to the support structure 300 through the contact surface between the connecting sleeve 224 and the support structure 300. The annular structure of the connecting sleeve 224 allows the tension force to be evenly distributed along the periphery of the support structure 300, ensuring the uniformity and stability of force transmission.

[0080] The driving component 222 applies a downward pulling force to the connecting sleeve 224 via the connecting steel cable 223. The connecting sleeve 224 transmits this pulling force to the top of the support structure 300, causing the entire support structure 300 to be subjected to downward tension. The support structure 300 includes a support ring 310 and multiple hinge structures 320. The top of each hinge structure 320 is connected to the adaptive adjustment mechanism 200. When the top of the support structure 300 is subjected to downward tension, this force is transmitted to the bottom of each hinge structure 320 through each hinge structure 320. Since each hinge structure 320 is inclined upward from the connecting seat 100 toward the adaptive adjustment mechanism 200, the downward tension generates an upward lifting force component at the bottom of each hinge structure 320. This lifting force component acts on the connecting seat 100, achieving support and lifting of the connecting seat 100.

[0081] This application optimizes the structure and improves the function of the connecting assembly 221 through the combined configuration of the connecting steel cable 223 and the connecting sleeve 224. The flexible force transmission characteristics of the connecting steel cable 223 provide a highly adaptable connection method for the drive mechanism 220, capable of adapting to minor displacements and angular changes in the supporting structure 300 during operation, maintaining the stability and reliability of the connection. The sleeve connection method of the connecting sleeve 224 ensures the uniform distribution and effective transmission of tension force, avoiding structural deformation or connection failure caused by localized stress. The division of labor and cooperation between the connecting steel cable 223 and the connecting sleeve 224 gives the connecting assembly 221 good force transmission performance and structural adaptability.

[0082] Compared to the rigid connecting rod directly connecting the drive component 222 and the support structure 300, this application adopts a flexible connection method using a connecting steel cable 223. The connecting steel cable 223 can adapt to the displacement changes of the support structure 300 during adjustment, avoiding additional bending moments or shear forces caused by rigid connections, thus improving the reliability and durability of the connection. Moreover, compared to other complex force transmission devices, this application uses a simple combination of connecting steel cable 223 and connecting sleeve 224. The tensile characteristics of the connecting steel cable 223 and the sleeve structure of the connecting sleeve 224 form an efficient force transmission path, simplifying the structural complexity, reducing manufacturing costs and installation difficulty while ensuring the force transmission effect. This further improves the practicality and economy of the connecting component 221 and enhances the applicability and reliability of the drive mechanism 220 in soft soil foundation engineering.

[0083] Please continue reading. Figure 1 and Figure 3 In an embodiment of the present invention, the adaptive adjustment mechanism 200 further includes a plurality of second lugs 230 and a plurality of second steel cables 240. The number of second lugs 230 is the same as the number of second steel cables 240 and they are arranged in a one-to-one correspondence. The plurality of second lugs 230 are connected at intervals to the top of the support ring 210 along the outer edge of the connecting seat 100. Each second lug 230 is connected to the external soil through a corresponding second steel cable 240. Each second steel cable 240 is used to tension the corresponding second lug 230 so that the support ring 210 is supported on the soft soil layer. The second lugs 230 and the first lugs 330 are arranged alternately.

[0084] Specifically, the support ring 210 is sleeved on the outside of the support structure 300. Multiple second lugs 230 are spaced apart and connected to the top of the support ring 210 along the outer edge of the connecting seat 100. The second lugs 230 are securely connected to the top of the support ring 210 by welding, bolting, or other fixing methods. The number of second lugs 230 corresponds to the number of second steel cables 240, with each second lug 230 equipped with a corresponding second steel cable 240, forming a one-to-one pairing relationship. Each second lug 230 is connected to the external soil via a corresponding second steel cable 240. One end of the second steel cable 240 is connected to the second lug 230, and the other end extends into the external soil and connects to the soil anchoring structure. The second steel cable 240 is used to tension the corresponding second lug 230, applying an outward pulling force to the second lug 230 when under tension. Understandably, the adaptive adjustment mechanism 200 includes a support ring 210 and multiple drive mechanisms 220. The support ring 210 is connected to the external soil through multiple second lugs 230 and multiple second steel cables 240. The second lugs 230 are installed on the support ring 210 as connection nodes, and the second steel cables 240 connect the support ring 210 to the external soil as force transmission components. Each second steel cable 240 applies tension to the corresponding second lug 230, so that the support ring 210 is supported on the soft soil layer by the combined action of the second lugs 230 and the second steel cables 240.

[0085] More specifically, the second lug 230 and the first lug 330 are staggered, and the second lug 230 and the first lug 330 are distributed at intervals on the periphery of the support ring 210, maintaining a certain angular distance between the two types of lugs. The first lug 330 is connected to the support ring 210 and to relevant components of the support structure 300, while the second lug 230 is connected to the support ring 210 and to the external soil. The staggered arrangement of the first lug 330 and the second lug 230 allows the support ring 210 to simultaneously withstand multi-directional forces from the support structure 300 and the external soil. The spaced connections of the second lugs 230 are distributed along the outer edge of the connecting seat 100, and the positions of the second lugs 230 correspond to the radial positions of the connecting seat 100, so that the tension of the second steel cable 240 can effectively balance the stress state of the connecting seat 100 in the soft soil layer.

[0086] When each of the second steel cables 240 is tensioned to its corresponding second lug 230, the second steel cable 240 applies an outward tension to the second lug 230, which is transmitted to the support ring 210 through the second lug 230. The distribution of multiple second lugs 230 along the periphery of the support ring 210 results in a uniform radial tension distribution of the tension of each second steel cable 240 on the support ring 210. The resultant force of all radial tensions forms an upward lifting force at the center of the support ring 210. Under the action of the tension of the second steel cables 240, the support ring 210 remains in a stable suspended state, supported and lifted above the soft soil layer by the combination of the second lugs 230 and the second steel cables 240.

[0087] The connection between the second steel cable 240 and the external soil provides stable external support for the support ring 210. The second steel cable 240 can be reliably connected to the external soil through soil anchors, ground anchors, or other soil anchoring devices. The bearing capacity and stability of the external soil provide reliable reaction support for the second steel cable 240, enabling it to withstand the weight of the support ring 210 and the transmitted load. The tension adjustment of the second steel cable 240 allows for precise control of the tension according to the deformation state of the soft soil layer and the lifting requirements of the support ring 210.

[0088] The staggered arrangement of the second lug 230 and the first lug 330 achieves a uniform distribution of forces on the support ring 210 and a stable structural balance. The first lug 330 bears the force from the supporting structure 300, while the second lug 230 bears the reaction force from the external soil. The staggered arrangement of the two lugs ensures that various forces form a balanced stress state on the support ring 210. The number and position of the second lug 230 are coordinated with the first lug 330 to ensure that the support ring 210 maintains a stable working state under various load conditions.

[0089] This application achieves a complete and enhanced support system for the adaptive adjustment mechanism 200 through the coordinated configuration of multiple second lugs 230 and multiple second steel cables 240. The one-to-one correspondence between the second lugs 230 and the second steel cables 240 ensures that each connection point has an independent force transmission path and adjustment capability, improving the reliability and adjustment accuracy of the support system. The spaced distribution of the second lugs 230 along the outer edge of the connecting seat 100 allows the support ring 210 to uniformly bear the support force of the external soil, avoiding uneven deformation or stress concentration caused by localized stress.

[0090] Compared to traditional structures with a single support method, this application provides additional external support to the adaptive adjustment mechanism 200 through the connection between the second lug 230 and the second steel cable 240 and the external soil. The support ring 210 not only relies on its own structure for load-bearing capacity but also utilizes the load-bearing capacity of the external soil through the second steel cable 240, significantly improving the overall structural stability and load-bearing capacity. Moreover, compared to other complex multi-point support devices, this application uses a simple combination of the second lug 230 and the second steel cable 240. The connection function of the second lug 230 and the force transmission characteristics of the second steel cable 240 form a highly efficient external support system. While ensuring the support effect, it simplifies the structural complexity, reduces construction difficulty and maintenance costs, further improves the practicality and economy of the adaptive adjustment mechanism 200, and enhances the applicability and reliability of the overall structure in soft soil foundation engineering.

[0091] Please continue reading. Figure 1 , Figure 2 and Figure 4 In an embodiment of the present invention, the connecting seat 100 includes a steel sleeve 110 and a plurality of vertical ribs 120. The steel sleeve 110 is a hollow sleeve with an open top. The steel sleeve 110 is buried in a soft soil layer. The top end of the steel sleeve 110 extends upward out of the surface of the soft soil layer to form an adaptive end 101. The adaptive end 101 has a plurality of connecting holes 102. The bottom end of the support structure 300 is connected to the adaptive end 101 through the plurality of connecting holes 102. The plurality of vertical ribs 120 are arranged at intervals along the circumference of the wind turbine tower in the steel sleeve 110. The wind turbine tower is installed on the plurality of vertical ribs 120 through flanges.

[0092] Specifically, the steel sleeve 110 is embedded in the soft soil layer, with its main body located inside. The steel sleeve 110 is embedded by excavating pre-drilled holes or by direct pressing. The steel sleeve 110 is a hollow sleeve with an open top and a closed bottom, forming a hollow cavity inside. The top of the steel sleeve 110 extends upwards beyond the surface of the soft soil layer, forming an adaptive end 101. The adaptive end 101 is the portion of the steel sleeve 110 exposed above the soft soil layer surface, and its height can be adjusted according to the connection requirements of the supporting structure 300. The adaptive end 101 has multiple connecting holes 102, which are spaced along its periphery. The connecting holes 102 are circular holes or other shaped through holes. The bottom end of the support structure 300 is connected to the adaptive end 101 through multiple connecting holes 102. The support structure 300 includes a support ring 310 and multiple hinge structures 320. The bottom end of each hinge structure 320 is connected to the adaptive end 101 through bolts, pins, or other connecting parts passing through the connecting holes 102. Understandably, the connecting seat 100 is embedded in the soft soil layer through a steel sleeve 110, with the adaptive end 101 of the steel sleeve 110 exposed on the surface of the soft soil layer. The support structure 300 is connected to the adaptive end 101 through the connecting holes 102. The steel sleeve 110, as the main load-bearing structure of the connecting seat 100, bears various loads from the support structure 300. The adaptive end 101, as a connection interface, provides a connection point for the support structure 300, thereby realizing the load-bearing connection function of the connecting seat 100, enabling the support structure 300 to establish a stable support foundation in the soft soil layer through the connecting seat 100.

[0093] More specifically, multiple vertical ribs 120 are spaced apart circumferentially within the steel sleeve 110 along the tower of the wind turbine generator. The vertical ribs 120 are vertical steel bars or structural steel, and their number is determined based on the tower diameter and load requirements. The vertical ribs 120 are evenly distributed circumferentially within the steel sleeve 110, with their bottom ends fixed to the bottom of the sleeve and their top ends extending to the top opening of the sleeve. The wind turbine generator tower is mounted to the vertical ribs 120 via flanges. A bottom flange is provided at the bottom of the tower, and it is bolted to the top of each vertical rib 120, thus securing the tower to the ribs. The circumferential distribution of the vertical ribs 120 corresponds to the connection holes 102 of the bottom flange, ensuring stable installation of the tower on the vertical ribs 120.

[0094] When the support structure 300 applies a lifting force to the connecting seat 100 through the adaptive adjustment mechanism 200, the lifting force is transmitted to the adaptive end 101 through the connecting hole 102, and the adaptive end 101 transmits the lifting force to the steel sleeve 110. The steel sleeve 110, as the main structure of the connecting seat 100, bears the lifting force and distributes it to the surrounding soft soil layer. The embedment depth of the steel sleeve 110 and its contact area with the soft soil layer provide a sufficient bearing foundation for the lifting force. The hollow structure of the steel sleeve 110 reduces the self-weight of the connecting seat 100 and provides installation space for the vertical reinforcement 120.

[0095] Vertical ribs 120 are installed inside the steel sleeve 110, bearing the weight of the wind turbine tower and various loads such as wind loads. The vertical ribs 120 transfer the tower load to the bottom of the steel sleeve 110, which then transfers the load to the soft soil layer. The circumferential distribution of the vertical ribs 120 ensures that the tower load is evenly distributed to the steel sleeve 110, avoiding stress concentration or structural deformation caused by localized stress. The combination of the vertical ribs 120 and the steel sleeve 110 forms a stable load-bearing system, providing reliable foundation support for the wind turbine.

[0096] The connection holes 102 of the adaptive end 101 provide a flexible connection method for the support structure 300. The number and position of the connection holes 102 can be adjusted according to the configuration of the support structure 300. The spacing of the connection holes 102 ensures that each hinge structure 320 of the support structure 300 can be evenly connected to the adaptive end 101, guaranteeing the stability of the connection and the uniformity of load transfer. The configuration of the adaptive end 101 exposed on the surface of the soft soil layer facilitates the installation and adjustment of the support structure 300, while avoiding the direct impact of soft soil layer deformation on the connection part.

[0097] The embedded configuration of the steel sleeve 110 provides a stable foundation anchorage for the connecting seat 100. The friction and lateral earth pressure between the steel sleeve 110 and the soft soil layer provide the connecting seat 100 with pull-out and overturning resistance. The hollow structure of the steel sleeve 110 reduces material usage while ensuring load-bearing capacity, thus lowering the manufacturing cost of the connecting seat 100. The vertical ribs 120 inside the steel sleeve 110 enable effective transfer of tower load, and the circumferential distribution of the vertical ribs 120 ensures uniform load transfer and structural stability.

[0098] This application optimizes the structure and improves the function of the connecting seat 100 through the combined configuration of the steel sleeve 110 and the vertical rib 120. The embedded bearing of the steel sleeve 110 and the load transfer of the vertical rib 120 form a complete foundation support system, providing a stable connection foundation for the supporting structure 300 and reliable load-bearing support for the wind turbine generator. The configuration of the connecting hole 102 of the adaptive end 101 and the circumferential distribution of the vertical rib 120 enable the connecting seat 100 to simultaneously meet the connection requirements of the supporting structure 300 and the tower, realizing an integrated foundation solution.

[0099] Compared to traditional solutions with separate foundation structures, this application utilizes an integrated configuration with vertical reinforcement 120 within the steel sleeve 110. The connecting seat 100 simultaneously serves the dual functions of connecting the supporting structure 300 and supporting the tower, simplifying the complexity of the foundation structure, reducing construction procedures and material usage, and improving construction efficiency and economy. Moreover, compared to other complex foundation bearing devices, this application employs a simple combination of the steel sleeve 110 and vertical reinforcement 120. The embedded bearing of the steel sleeve 110 and the load transfer of the vertical reinforcement 120 form a highly efficient foundation support system. While ensuring load-bearing performance, it simplifies structural complexity, reduces construction difficulty and maintenance costs, further enhances the practicality and economy of the connecting seat 100, and strengthens the applicability and reliability of the overall foundation structure in soft soil engineering.
