Description

Technical Field

[0001] The invention relates to the field of wind power, and in particular to a foundation structure for a wind turbine generator set and a wind turbine generator set. Background Art

[0002] Traditional offshore jacket foundation structures, such as suction bucket foundations and steel pipe pile foundations, have been widely used in shallow waters and areas with relatively simple geological conditions. However, there are still many challenges when expanding to deeper waters and areas with more complex seabed geological structures.

[0003] Although the suction bucket foundation exhibits good bearing capacity and stability in shallow waters, its long-term stability is greatly affected by seabed scouring and geological changes in sea areas with increased water depth, faster current speed and complex seabed geological conditions.

[0004] Steel pipe pile foundations provide support by driving them into the seabed to a certain depth, but in deep soft soil or rock layers, the difficulty and cost of driving piles increase significantly.

[0005] With the advancement of offshore wind power technology, deep sea areas have become an important direction for future wind power development. However, the deeper water and more complex seabed geological structure in deep sea areas put forward higher requirements on the bearing capacity, stability and construction convenience of wind power foundation structures.

[0011] According to some embodiments of the present invention, the connecting component extends obliquely from the top surface of the suction bucket away from the pile sleeve, and the extending direction of the connecting component is parallel to the extending direction of the pile sleeve.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In related technologies, with the advancement of offshore wind power technology, deep sea areas have become an important direction for future wind power development. However, the water depth in deep sea areas is deeper and the seabed geological structure is more complex, which puts higher requirements on the bearing capacity, stability and construction convenience of wind power foundation structures.

[0039] Reference below Figure 1-Figure 6 A basic structure 1 according to an embodiment of the present invention is described.

[0040] like Figure 1-Figure 6 As shown, the foundation structure 1 according to the present invention is used for a wind turbine generator set, and the foundation structure 1 includes a suction bucket 11, a connecting component 12 and a piling component 13. A pressure regulating chamber is formed in the suction bucket 11; the connecting component 12 is fixedly arranged on the top surface of the suction bucket 11 and is suitable for being connected with the guide tube frame 3; the piling component 13 is arranged on one side of the suction bucket 11 and is formed with a piling channel suitable for the pipe pile 2 to pass through.

[0041] According to the foundation structure 1 of the present invention, the suction bucket 11 is generally cylindrical or similar in shape, and is used to be inserted and fixed in the soil on the seabed. A pressure regulating chamber is formed inside the suction bucket 11, which allows the foundation structure 1 to sink by adjusting the pressure difference between the inside and outside of the chamber. By draining or pumping air to reduce the pressure in the pressure regulating chamber, the pressure outside the suction bucket 11 will be greater than the pressure inside the pressure regulating chamber, and a negative pressure will be generated between the wall of the suction bucket 11 and the surrounding soil, pushing the foundation structure 1 to sink automatically, thereby simplifying the construction process. The connecting component 12 is fixedly arranged on the top surface of the suction bucket 11 to provide a stable connection point so as to connect the conductor frame 3 with the foundation structure 1. The piling component 13 is arranged on one side of the suction bucket 11 to provide a piling channel, which allows the pipe pile 2 to pass through and be driven into a deeper soil layer. The piling channel needs to ensure that the pipe pile 2 can pass smoothly and be accurately positioned without affecting the function of the connecting component 12. By driving the pipe pile 2 around the foundation structure 1, the stability and bearing capacity of the entire foundation structure 1 can be further increased. The pipe piles 2 are able to reach firmer ground, thereby providing additional support.

[0042] Therefore, the foundation structure 1 according to the present invention can significantly improve the construction convenience of wind power development in deep sea areas, the bearing capacity and stability of the foundation structure 1, and through the negative pressure sinking mechanism of the suction bucket 11 and the reinforced support of the piling component 13, it can effectively cope with complex seabed geological conditions and promote the development of offshore wind power technology to the deep sea.

[0043] According to some embodiments of the present invention, Figure 1 and Figure 2As shown, the pile driving component 13 includes a mud entry sleeve 131 and a pile sleeve 132. The mud entry sleeve 131 is arranged on one side of the suction barrel 11 and connected to the suction barrel 11, so that the mud entry sleeve 131 can sink driven by the suction barrel 11, and the bottom surface of the mud entry sleeve 131 is in contact with the soil. The top surface of the mud entry sleeve 131 is coplanar with the top surface of the suction barrel 11, so that the top surface of the mud entry sleeve 131 and the top surface of the suction barrel 11 have a smooth transition, which reduces the stress concentration phenomenon caused by the height difference and enhances the structural strength. The pile sleeve 132 is fixedly arranged on the top surface of the mud entry sleeve 131, and the pile sleeve 132 and the mud entry sleeve 131 together form a pile driving channel. The pile driving channel runs through the entire pile driving component 13, and the pipe pile 2 can pass through smoothly and unimpeded and penetrate into the ground until it reaches a predetermined depth. The pile sleeve 132 can provide necessary support and guidance during the driving process of the pipe pile 2.

[0044] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the connecting member 12 extends obliquely from the top surface of the suction barrel 11 away from the pile sleeve 132. The oblique extension of the connecting member 12 means that the connecting member 12 does not extend perpendicularly to the top surface of the suction barrel 11, and the direction of the oblique extension of the connecting member 12 is toward the side away from the pile sleeve 132, while the pipe pile 2 penetrates into the soil through the pile sleeve 132 and is located on the side of the connecting member 12 away from the conductor frame 3. The extension direction of the connecting member 12 is parallel to the extension direction of the pile sleeve 132, so that the pipe pile 2 surrounds the conductor frame 3 without interfering with each other, and the two can operate freely within their respective functional ranges, and the efficiency or safety will not be reduced due to physical contact or influence between each other, so that the foundation structure 1 can maintain higher stability and reliability.

[0045] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the foundation structure 1 also includes a connecting plate 14, which is connected between the connecting component 12 and the pile sleeve 132 to transfer loads between the connecting component 12 and the pile sleeve 132, thereby enhancing the integrity and stability of the structure. A first connecting portion 141 is formed at one end of the connecting plate 14, and the first connecting portion 141 surrounds and is connected to the outer peripheral surface of the connecting component 12. The surrounding connection method not only increases the connection area, improves the strength and stability of the connection, but also can effectively disperse the stress between the connecting component 12 and the connecting plate 14. A second connecting portion 142 is formed at the other end of the connecting plate 14, and the second connecting portion 142 surrounds and is connected to the outer peripheral surface of the pile sleeve 132. Therefore, the second connecting portion 142 has the same advantages as the first connecting portion 141, namely, increasing the connection area, improving the connection strength and stability, and dispersing the stress.

[0046] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the connecting plates 14 are constructed in multiple configurations and are spaced apart in the extending direction of the connecting member 12. By increasing the number of connecting plates 14 and arranging them in the extending direction of the connecting member 12, the connection strength between the connecting member 12 and the pile sleeve 132 can be significantly enhanced. Each connecting plate 14 bears a part of the connecting force, and the multiple connecting plates 14 work together to make the overall connection more stable and reliable. The load transmitted between the connecting member 12 and the pile sleeve 132 will generate stress. By using multiple spaced connecting plates 14, the stress can be dispersed to a larger area, thereby reducing the risk of local stress concentration and improving the durability of the structure.

[0047] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, a guide portion 133 is formed at the free end of the pile sleeve 132. The guide portion 133 is used to assist and guide the pipe pile 2 to smoothly enter the pile sleeve 132 during the piling process, and ensure that the pipe pile 2 can accurately sink along the predetermined path and direction. A guide channel is formed in the guide portion 133, and the guide channel is connected to the piling channel. When the pipe pile 2 is driven into the soil, it needs to pass through the guide channel first and then enter the piling channel. The guide channel is open in the direction away from the pile sleeve 132, so that the pipe pile 2 can smoothly enter the guide channel and sink along the direction of the channel. The cross-section of the guide portion 133 is configured as an ellipse. The ellipse cross-section has a guiding property, which can better guide the pipe pile 2 to enter the guide channel and sink along the predetermined path. The cross-sectional area of ​​the guide portion 133 gradually increases in the direction away from the pile sleeve 132. The guide channel is relatively narrow at the entrance and relatively wide at the exit, allowing the pipe pile 2 to have a certain deviation or misalignment when entering the guide channel. However, as the pipe pile 2 sinks, the pipe pile 2 will gradually be adjusted and corrected to the correct position by the guide channel, thereby improving the fault tolerance of the piling process.

[0048] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, a plurality of reinforcing ribs 111 are formed on the top surface of the suction bucket 11, and the reinforcing ribs 111 are used to enhance the structural strength and rigidity. By providing the reinforcing ribs 111 on the top surface of the suction bucket 11, the bearing capacity and stability can be effectively improved. The plurality of reinforcing ribs 111 are connected to the connecting component 12, which can further reinforce the connecting component 12, help it to bear the load, and effectively transfer the load to other parts of the base structure 1. The plurality of reinforcing ribs 111 are radially arranged around the connecting component 12 at intervals, so that each reinforcing rib 111 can transfer the load at an optimal angle and path, avoiding stress concentration and lengthy transfer paths. At the same time, the interval arrangement method can prevent the reinforcing ribs 111 from interfering with each other, and each can exert the maximum reinforcement effect.

[0049] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the piling components 13 are constructed in multiple configurations and are arranged at intervals around the suction barrel 11 on one side of the connecting component 12, so that the foundation structure 1 can provide a piling channel for multiple pipe piles 2, thereby allowing stable anchoring in a wider area. Multiple piling components 13 are located on one side of the connecting component 12, so that the multiple piling components 13 do not interfere with the conductor frame 3. Multiple piling components 13 are arranged at intervals around the suction barrel 11, so that after the connecting component 12 is connected to the conductor frame 3, a stable and balanced support system can be formed, which reduces the pressure on a single piling component 13 by dispersing the load, and improves the durability of the overall structure.

[0050] According to the following Figure 3-Figure 6 The wind turbine according to the present invention is briefly described.

[0051] The wind turbine generator set according to the present invention comprises a foundation structure 1 and a jacket 3 in any one of the above embodiments, and the jacket 3 is connected to the connection component 12 of the foundation structure 1. Since the wind turbine generator set according to the present invention comprises the jacket 3 in any one of the above embodiments, the wind turbine generator set according to the present invention can significantly improve the installation efficiency, operation stability and carrying capacity in deep sea areas, and promote the development of offshore wind power technology to a larger scale and deeper sea areas.

[0052] According to some embodiments of the present invention, Figure 3-Figure 6 As shown, the foundation structure 1 is constructed in multiple ways, so that multiple foundation structures 1 can provide support together, thereby enhancing stability and bearing capacity. Not only does it disperse the weight and load from the upper structure, but it also improves the overall stiffness of the structure through the synergy of multiple support points. And each foundation structure 1 can be installed with at least one pipe pile 2. The pipe pile 2 is a component that penetrates deep into the soil and provides the main bearing capacity. Its number, position and depth can be adjusted according to specific geological conditions and design requirements. By installing one or more pipe piles 2 on each foundation structure 1, the bearing performance and stability can be further optimized.

[0053] Multiple foundation structures 1 are arranged at intervals around the conductor frame 3 and connected to the conductor frame 3. Not only does it achieve coordinated support between the foundation structures 1, but it also uses the conductor frame 3 as the central connection point to tightly connect the various foundation structures 1 into a whole. The surrounding and spaced arrangement ensures balanced force in all directions, thereby effectively resisting impact and further enhancing stability. In addition, multiple pipe piles 2 can be arranged in accordance with multiple foundation structures 1 to achieve spaced arrangement around the conductor frame 3, which can better adapt to geological conditions and evenly transfer the upper load to the soil below, so that each pipe pile 2 can give full play to its bearing capacity.

[0054] The following describes the construction process for the wind turbine generator system according to the present invention.

[0055] First, the floating crane vessel and the self-propelled deck barge are precisely positioned at the predetermined construction location. Subsequently, the crane vessel moves its crane to the top of the conductor frame 3 to be installed, and the lifting point on the top of the conductor frame 3 is firmly connected to the main hook of the crane through rigging. After confirming that the connection is stable, the crane is started to lift the conductor frame 3 to a certain height to provide sufficient space for the subsequent lowering operation. Subsequently, the conductor frame 3 is slowly lowered so that the suction bucket 11 part gradually enters the water until it reaches the depth specified in the design, at which time the sinking process of the conductor frame 3 begins. As the suction bucket 11 continues to enter the soil, its side friction resistance gradually increases until the foundation structure 1 stops sinking naturally due to excessive resistance. At this time, the pumping and drainage operation of the pressure regulating chamber is started, and the conductor frame 3 and the suction bucket 11 are prompted to continue to sink by increasing the pressure difference between the inside and outside of the pressure regulating chamber. During the sinking process, by finely adjusting the drainage speed of the pressure regulating chamber, the verticality of the foundation structure 1 entering the mud is effectively controlled to ensure construction accuracy. When the top cover of the suction bucket 11 contacts the mud surface on the seabed, the pumping operation is continued to form a significant negative pressure environment in the pressure regulating chamber. The negative pressure will cause the soil in the suction bucket 11 to compress and consolidate, thereby significantly improving the bearing capacity and stability of the foundation, and providing a solid guarantee for the long-term safe operation of wind power equipment. After the sinking and consolidation of the conductor frame 3 and the suction bucket 11 are completed, according to the design requirements, appropriate pile driving equipment is used to drive the pipe piles 2 through the pile driving channel reserved in the conductor frame 3 and into deeper strata to further enhance the stability and bearing capacity of the entire foundation structure 1.

[0056] After the conductor frame 3 sinks and reaches the predetermined position, the pile sinking stage of the pipe pile 2 is immediately entered. The crane ship uses special pile lifting equipment to accurately lift the pipe pile 2 and lift it into the preset fixed position of the piling channel. The pipe pile 2 is accurately positioned through the guiding effect of the guide channel. Subsequently, the pipe pile 2 is slowly lowered to the predetermined depth to ensure that the pile body is vertical and the position is accurate. The pile sinking process of direct sleeve driving with a hydraulic impact hammer is used to sink the pipe pile 2. During the pile sinking process, the hydraulic impact hammer generates a strong impact force to overcome the resistance of the soil layer and bedrock, and gradually drives the pipe pile 2 into the ground. When the lifting ears and clamps of the pipe pile 2 have completed their mission, they need to be cut off. Subsequently, the crane ship carries its own hydraulic impact hammer, rotates the boom to the top of the pile to be sunk, performs pile and sleeve operations, and continues the pile sinking operation until the steel pipe pile 2 is sunk to the unevenly weathered bedrock surface. During the pile driving process, if isolated rocks or uneven weathering are encountered, there is no need to cut the piles and the pile driving operation can continue, thus effectively adapting to the complex situation of large height differences and uneven bedrock surfaces.
