Description

Technical Field

[0001] The utility model relates to the field of offshore wind power generation, in particular to a support assembly for a floating wind power foundation and a floating wind power foundation. Background Art

[0002] The main construction material of the current floating wind power foundation is steel, and the construction cost is relatively high. As offshore wind turbines are becoming increasingly large, the steel consumption of the floating wind power foundation has gradually increased, which further increases the construction and installation costs of the floating wind power foundation. Considering factors such as sea use resources, installation and transportation, and the maturity of floating wind power development technology, semi-submersible floating foundations are generally adopted in China as carriers for high-power wind turbines to provide better platform motion performance. The current structural form of the semi-submersible wind power foundation is composed of support structures in different directions connected to each other. Especially for the upper support structure, complex connection structures and numerous mutual supports are mostly adopted to improve stability. However, the dense and complex support structures not only make the cost of the wind power foundation high, but also increase the number of node positions that need to be inspected for safety, thereby increasing the operation and maintenance difficulties. However, directly reducing the number of connection structures on the existing support structure is difficult to meet the strength requirements of the wind power foundation, and the stability is poor.

[0003] It can be seen that the existing technology has problems in that it is difficult to balance the construction cost, operation and maintenance difficulties, and structural strength requirements of the wind power foundation. Summary of the Utility Model

[0004] The utility model provides a support assembly for a floating wind power foundation and a floating wind power foundation, which solves the problems in the existing technology that it is difficult to balance the construction cost, operation and maintenance difficulties, and structural strength requirements.

[0006] The reinforcing member is connected to the corner of the A-shaped support frame and is in the same plane as the A-shaped support frame.

[0007] The support assembly of the floating wind power foundation of the present utility model utilizes an A-shaped support frame to construct a triangular stable support structure, and strengthens the structural strength of the support assembly by arranging strengthening members at the corners. The overall structure of the support assembly is simple, which not only reduces the connection stress points between the connection structures, effectively reduces the risk of structural fatigue, but also reduces the steel consumption and the construction cost. In addition, for floating foundations with mooring points above or near the waterline, the A-shaped support frame constructs an outward-expanded avoidance space with two protruding ends, enabling a relatively large open space in the upper part of the floating wind power foundation, facilitating the maintenance mother ship to avoid structures such as mooring anchor chains, and making the maintenance operation safer and more convenient.

[0008] Optionally, the A-shaped support frame includes a first strut, a second strut, and a third strut;

[0009] The first end of the first strut is connected to the first end of the second strut to form the tip of the A-shaped support frame, and both ends of the third strut are respectively connected to the first strut and the second strut, so that: the second end of the first strut and the second end of the second strut serve as two protruding ends.

[0014] In the embodiment of the present utility model, by designing the first strut and / or the second strut into a variable cross-section shape, the structural strength of the first strut and / or the second strut at the stress concentration position is improved, the risk of structural fatigue at the stress point is further reduced, and the structural strength and stability of the support assembly of the floating wind power foundation are improved.

[0015] Optionally, there are multiple strengthening members, and the multiple strengthening members include a first strengthening member, a second strengthening member, and a third strengthening member. There are a first corner, a second corner, and a third corner of the A-shaped support frame within the triangular area enclosed by the first strut, the second strut, and the third strut.

[0016] The two ends of the first reinforcing member are respectively connected to the first strut and the second strut and are located at the first corner. The two ends of the second reinforcing member are respectively connected to the second strut and the third strut and are located at the second corner. The two ends of the third reinforcing member are respectively connected to the first strut and the third strut and are located at the third corner.

[0017] In the embodiment of the present utility model, multiple triangular structures are constructed within the A-shaped support frame by multiple reinforcing members, improving the buckling resistance of the support assembly of the floating wind power foundation, and thus being beneficial to improving the structural strength and stability of the floating wind power foundation.

[0018] Optionally, the reinforcing member is a strut or a gusset plate.

[0020] Optionally, the A-shaped support frame is an axisymmetric structure, and the axis of symmetry of the A-shaped support frame passes through the tip of the A-shaped support frame and the midpoints of the two protruding ends.

[0021] Adopting the above structure can enable the support assembly of the floating wind power foundation to have better balance on the sea surface, contributing to the safe operation of the offshore wind turbine equipment.

[0022] The present utility model also provides a floating wind power foundation, including the support assembly of the floating wind power foundation involved in the above embodiments and possible implementation manners, and further including a first column, a second column, a third column, and a floating body assembly. The first column, the second column, and the third column are distributed in a triangle, and the offshore wind turbine equipment is arranged on the first column;

A stable triangular support structure is constructed by using the A-shaped support frame, and the structural strength of the support assembly of the floating wind power foundation is increased by arranging reinforcing members at the corners. The overall structure of the support assembly is simple, which not only reduces the connection stress points of each connection structure, effectively reduces the risk of structural fatigue, but also reduces the steel consumption and the construction cost. In addition, for floating foundations with mooring points above or near the waterline, since the support assembly of the floating wind power foundation of the embodiment of the present utility model constructs an outward-expanded avoidance space by using the two protruding ends, a relatively large open space can be provided in the upper part of the floating wind power foundation, facilitating the maintenance mother ship to avoid structures such as mooring anchor chains, making the maintenance operation safer and more convenient.

This embodiment is implemented on the premise of the technical solution of the present utility model, and the detailed implementation method and specific operation process are given, but the protection scope of the present utility model is not limited to the following embodiments.

[0043] In the description of this embodiment, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific situations.

[0044] To make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0045] Please refer to Figures 1 to 2 , the present utility model provides a support assembly 1 for a floating wind power foundation (as shown by the solid lines in Figure 1 and Figure 2 ), which includes an A-shaped support frame 30 and a reinforcing member. The A-shaped support frame 30 has a tip 34 and two protruding ends, the protruding end 35 and the protruding end 36. The tip 34 and the two protruding ends (the protruding end 35 and the protruding end 36) of the A-shaped support frame 30 are respectively fixed to the top side wall of a column of the floating wind power foundation 2. The reinforcing member (such as the first reinforcing member 41, the second reinforcing member 42, and the third reinforcing member 43) is connected to the corner of the A-shaped support frame 30 and is in the same plane as the A-shaped support frame 30.

[0046] With the above structure, a triangular stable support structure is constructed by using the A-shaped support frame 30, and the structural strength of the support assembly is increased by arranging the reinforcing member at the corner. The overall structure of the support assembly is simple, which not only reduces the connection stress points of each support structure, effectively reduces the risk of structural fatigue, but also reduces the steel consumption and the construction cost. In addition, for a floating foundation with a mooring point above or near the water line, the A-shaped support frame 30 constructs an outwardly expanding avoidance space by using the two protruding ends (such as the protruding end 35 and the protruding end 36), which can make the upper part of the floating wind power foundation have a larger open space, facilitating the maintenance mother ship to avoid structures such as mooring anchor chains, making the maintenance operation safer and more convenient.

[0047] Among them, the tip 34, the protruding end 35, and the protruding end 36 of the A-shaped support frame 30 are respectively fixed to a column of the floating wind power foundation 2 or it can be understood that the tip 34, the protruding end 35, and the protruding end 36 are fixed to different columns. Those skilled in the art can understand that the number of columns of the floating wind power foundation 2 is not limited. As shown in Figure 1 and Figure 2 , it can be three, or more than three. As long as the tip 34, the protruding end 35, and the protruding end 36 of the A-shaped support frame 30 are fixed to three different columns, it does not deviate from the scope of the embodiments of the present application.

[0048] In one embodiment, the A-shaped support frame 30 can be an integral structure formed by opening holes in a plate-like structure. In other alternative embodiments, it can be formed by splicing a plurality of strip-like structures. Specifically, for example, as shown in Figure 1 and Figure 2 , the A-shaped support frame 30 includes a first strut 31, a second strut 32, and a third strut 33.

[0049] The first end of the first strut 31 is connected to the first end of the second strut 32 to form the tip 34 of the A-shaped support frame. The two ends of the third strut 33 are respectively connected to the first strut 31 and the second strut 32, such that: the second end of the first strut 31 and the second end of the second strut 32 serve as two protruding ends (the protruding end 35 and the protruding end 36).

[0050] Wherein, the tip 34 can be formed by directly connecting the first end of the first strut 31 and the first end of the second strut 32 together, or can be formed by indirectly connecting them together. For example Figure 1 and Figure 2 as shown, the first end of the first strut 31 and the second end of the second strut 32 are both connected to the column, and thus jointly form the tip 34 with a partial side wall of the column.

[0051] The A-shaped support frame 30 is formed by the ingenious arrangement of the first strut 31, the second strut 32 and the third strut 33 into an A-shaped structure, which reduces the span between the first strut 31 and the second strut 32, improves the buckling resistance of the support assembly of the floating wind power foundation, and improves the stability and anti-interference ability (such as sea breeze and sea waves, etc.). Moreover, since the third strut 33 avoids directly connecting to the column carrying the offshore wind turbine equipment, it reduces the complexity of the connection between the entire floating wind power foundation and the disturbance end, and reduces the risk of structural failure.

[0052] Furthermore, those skilled in the art can understand that the corner of the A-shaped support frame 30 can be the interior angle of the triangular area formed by the first strut 31, the second strut 32 and the third strut 33, or can be the exterior angle of this triangular area. For example, the angle at the intersection of the third strut 33 and the first strut 31 and located outside this triangular area, and the angle at the intersection of the third strut 33 and the second strut 32 and located outside this triangular area. The reinforcing member can be provided at any of the above corners.

[0053] In one embodiment, as Figure 1 and Figure 2As shown in the figure, there are multiple reinforcing members, and the multiple reinforcing members include a first reinforcing member 41, a second reinforcing member 42, and a third reinforcing member 43. Within the triangular region formed by enclosing the first strut 31, the second strut 32, and the third strut 33, there are a first corner 301, a second corner 302, and a third corner 303 of the A-shaped support frame 30. Two ends of the first reinforcing member 41 are respectively connected to the first strut 31 and the second strut 32 and are located at the first corner 301. Two ends of the second reinforcing member 42 are respectively connected to the second strut 32 and the third strut 33 and are located at the second corner 302. Two ends of the third reinforcing member 43 are respectively connected to the first strut 31 and the third strut 33 and are located at the third corner 303. Through the above structure, multiple reinforcing members construct multiple triangular structures within the A-shaped support frame 30, improving the buckling resistance of the A-shaped support frame 30, and further improving the structural strength and stability of the support assembly 1 of the floating wind power foundation.

[0054] In the embodiment of the present utility model, the shape of the reinforcing member is not limited. In one embodiment, as Figure 1 shown, the reinforcing member is a strut, and it can be connected to two adjacent struts in a chamfered connection manner. In other alternative embodiments, as Figure 2 shown, the reinforcing member is a gusset plate. The gusset plate can be, for example, triangular. In one embodiment, the free edge of the gusset plate can be, for example, arc-shaped. Further, the material of the reinforcing member can be a metal material, such as steel, or it can also be a composite beam, such as a transverse load-bearing material formed by combining a steel beam and a concrete slab.

[0055] Further, in the embodiment of the present utility model, the shape of each of the above struts is not limited. In one embodiment, as Figure 3 shown, the cross-sectional shapes of the first strut 31, the second strut 32, and the third strut 33 are all rectangular. In one embodiment, as Figure 4 shown, the cross-sectional shapes of the first strut 31, the second strut 32, and the third strut 33 are all circular. In one embodiment, at least part of the A-shaped support frame 30 is a variable cross-section structure. For example, as Figure 5 shown, the first strut 31 includes a first strut main body section 311 and two first strut end sections 312 connected together. The first strut main body section 311 is located between the two first strut end sections 312, and the cross-sectional area of the first strut end section 312 is larger than the cross-sectional area of the first strut main body section 311. For example, the second strut 32 includes a second strut main body section 321 and two second strut end sections 322 connected together.

[0056] The second strut main body section 321 is located between the two second strut end sections 322, and the cross-sectional area of the second strut end section 322 is larger than the cross-sectional area of the second strut main body section 321.

[0057] Among them, the cross-sectional shapes of the first strut end segment 312 and the second strut end segment 322 can be, for example, circular, rectangular, rectangular with chamfers, and so on.

[0058] With the above structure, by designing the first strut 31 and / or the second strut 32 to have a variable cross-sectional shape, the structural strength of the first strut 31 and / or the second strut 32 at the stress concentration position is improved, the risk of structural fatigue at the stress point is further reduced, and the structural strength and stability of the support assembly of the floating wind power foundation are improved.

[0059] Further, please refer to Figures 6 to 8 , in the embodiment of the present utility model, the specific connection positions of the third strut 33 with the first strut 31 and the second strut 32 are not limited, and can be any position within the length ranges of the first strut 31 and the second strut 32. Or it can be understood that the distance between the third strut 33 and the tip 34 of the A-shaped support frame 30 is not limited. In one embodiment, as Figure 6 shown, the third strut 33 is arranged close to the tip 34 of the A-shaped support frame 30 to construct a relatively large outward expansion avoidance space for the operation of the maintenance mother ship. In other alternative embodiments, as Figure 8 shown, the third strut 33 can also be arranged relatively far from the tip 34 of the A-shaped support frame 30.

[0060] In one embodiment, as Figure 7 shown, the third strut 33 is arranged at the middle position between the first strut 31 and the second strut 32. For example, the triangular area formed by enclosing the first strut 31, the second strut 32, and the third strut 33 is an equilateral triangle. In other alternative embodiments, this triangular area can also be an isosceles triangle. Further, in one embodiment, the A-shaped support frame 30 is an axisymmetric structure, and the axis of symmetry of the A-shaped support frame 30 passes through the tip 34 of the A-shaped support frame 30 and the midpoints of the two protruding ends (the protruding end 35 and the protruding end 36). Adopting such a structure can enable the support assembly 1 of the floating wind power foundation to have better balance on the sea surface, which is helpful for the safe operation of the offshore wind turbine equipment.

[0061] The present utility model also provides a floating wind power foundation 2. Please refer to Figure 1 and Figure 2 , which includes the support assembly 1 of the floating wind power foundation involved in the above-mentioned various embodiments and possible embodiments, and also includes a first column 11, a second column 12, a third column 13, and a floating body assembly (such as a first floating rod 21, a second floating rod 22, and a third floating rod 23). The first column 11, the second column 12, and the third column 13 are distributed in a triangular shape, and the offshore wind turbine equipment is arranged on the first column 11.

[0062] The floating body assembly (such as the first floating rod 21, the second floating rod 22, and the third floating rod 23) is connected to the first column 11, the second column 12, and the third column 13.

[0063] As Figure 1 and Figure 2 shown, the support assembly 1 of the floating body wind power foundation is located on the upper side of the floating body assembly along the buoyancy direction. The tip 34 is connected to the top side wall of the first column 11, and the protruding ends 35 and 36 are respectively connected to the top side walls of the second column 12 and the third column 13.

[0064] For the floating wind power foundation 2 of the present utility model, the conventional four-column type in the traditional technical solution is simplified to a three-column type. The A-shaped support frame 30 is used to construct a triangular stable support structure, and the structural strength of the support assembly 1 of the floating wind power foundation is increased by arranging reinforcing members at the corners. The overall structure of the support assembly is simple, which not only reduces the connection stress points of each connection structure, effectively reduces the risk of structural fatigue, but also reduces the steel consumption and the construction cost. In addition, for a floating foundation with a mooring point above or near the waterline, since the support assembly 1 of the floating wind power foundation in the embodiment of the present utility model constructs an outward-expanded avoidance space by using two protruding ends, the upper part of the floating wind power foundation 2 can have a relatively large open space, which is convenient for the maintenance mother ship to avoid structures such as mooring anchor chains, making the maintenance operation safer and more convenient.

[0065] In one embodiment, the two ends of the first strut 31 are respectively connected to the top side wall of the first column 11 and the top side wall of the second column 12, the two ends of the second strut 32 are respectively connected to the top side wall of the first column 11 and the top side wall of the third column 13, and the two ends of the third strut 33 are respectively connected to the first strut 31 and the second strut 32. Among them, please refer to as Figure 2 shown, the first end of the first strut 31, the first end of the second strut 32, and a part of the side wall of the first column 11 together serve as the tip 34 of the A-shaped support frame 30, the second end of the first strut 31 serves as the protruding end 35 of the A-shaped support frame 30, and the second end of the second strut 32 serves as the protruding end 36 of the A-shaped support frame 30.

[0066] Those skilled in the art can understand that the shape of the floating body assembly is not limited. For example, it can be a block structure, a plate structure, a columnar structure, etc. In one embodiment, as Figure 1 and Figure 2As shown, the floating body assembly of the floating wind power foundation 2 in the embodiment of the present utility model includes a first floating rod 21, a second floating rod 22, and a third floating rod 23 connected together. The first floating rod 21, the second floating rod 22, and the third floating rod 23 enclose a triangular structure, and the three top ends of the triangular structure are respectively connected to the bottom side walls of the first column 11, the second column 12, and the third column 13. The above three top ends can be understood as follows: the first end of the first floating rod 21 and the first end of the second floating rod 22 are connected together to form a first top end, the second end of the first floating rod 21 and the first end of the third floating rod 23 are connected together to form a second top end, and the second end of the second floating rod 22 and the second end of the third floating rod 23 are connected together to form a third top end. Further, in an implementation manner, the interiors of the first floating rod 21, the second floating rod 22, and the third floating rod 23 are all hollow and the cross-sectional shapes are all rectangular. Further, reinforcing ribs are also provided inside the first floating rod 21, the second floating rod 22, and the third floating rod 23, and the shapes of the reinforcing ribs can be, for example, T-shaped, X-shaped, V-shaped, grid-shaped, cross-shaped, etc. The arrangement of the reinforcing ribs can increase the structural strength of the floating body assembly, make the floating body assembly have better impact resistance, and further improve the stability of the floating wind power foundation.

[0067] In the embodiment of the present utility model, the hollow floating body assembly (including the first floating rod 21, the second floating rod 22, and the third floating rod 23) can provide a certain displacement, reduce the draft in the migration and out-of-dock states, improve the applicable range and flexibility of the water depth of the dock channel during the construction and transportation processes. Moreover, the structure with a rectangular cross-sectional shape of each floating rod (such as the first floating rod 21, the second floating rod 22, and the third floating rod 23) has higher stiffness than the circular structure under the same steel consumption, making the stability and safety of the entire floating wind power foundation 2 better.

[0068] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
