Description

Technical Field

[0001] The present invention relates to the technical field of wind power equipment, and particularly relates to a floating wind power foundation and a wind power equipment. Background Art

[0002] Wind power energy is a pollution-free and renewable clean energy. Compared with onshore areas, deep-sea wind power generation is more stable and has a larger power generation capacity. In deep-sea areas, the construction of traditional fixed wind power foundations is difficult and costly, and is no longer applicable. Generally, floating wind power foundations are used. In order to reduce the swaying and heaving of the wind power foundation under wind and waves, some wind power foundations are provided with a number of anti-sway plates to reduce the swaying and heaving amplitudes and improve the stability. However, the existing structure and arrangement of the anti-sway plates have limited effects on reducing swaying and heaving, and the anti-overturning effect needs to be improved. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a floating wind power foundation that can effectively reduce the swaying and heaving amplitudes of the wind power foundation, improve the stability of the wind power foundation, and has a better anti-overturning effect.

[0004] The present invention also provides a wind power equipment having the above floating wind power foundation.

[0005] The floating wind power foundation according to the first aspect embodiment of the present invention includes at least one floating body unit. The floating body unit includes an annular floating body and an anti-sway plate assembly. The anti-sway plate assembly includes at least two anti-sway plates arranged vertically. The anti-sway plate is provided with a plurality of first spoiler holes that penetrate the anti-sway plate along the thickness direction of the anti-sway plate. The first spoiler holes of two adjacent anti-sway plates are vertically offset. The uppermost anti-sway plate is connected to the annular floating body, and an accommodation groove is formed between the upper surface of the uppermost anti-sway plate and the inner peripheral wall of the annular floating body.

[0006] The floating wind power foundation according to the embodiment of the present invention has at least the following beneficial effects: In this application, the floating body unit includes at least two anti-rolling plates arranged vertically one above the other, which impose greater damping on seawater. Moreover, each anti-rolling plate is provided with a first spoiler hole, and the first spoiler holes of two adjacent anti-rolling plates are vertically offset. In this way, when the seawater causes heaving on the wind power foundation, part of the seawater will flow through the first spoiler holes of multiple anti-rolling plates in sequence, thereby changing the flow direction of the seawater, making the seawater flow in multiple directions, increasing the flow path, effectively disturbing the vertical flow of the seawater, imposing greater additional damping on the heaving motion of the wind power foundation, and reducing the heaving motion amplitude and motion frequency of the wind power foundation. In addition, a receiving groove is formed by enclosing between the upper surface of the uppermost anti-rolling plate and the inner peripheral wall of the annular floating body. When part of the annular floating body sinks into the sea, the seawater will enter the receiving groove through the first spoiler holes. When the wind power foundation sways and heaves, the seawater in the receiving groove cannot quickly flow out of the first spoiler holes. Therefore, the seawater in the receiving groove can also play a certain ballast role, reducing the swaying and heaving amplitudes of the wind power foundation. In addition, when the wind power foundation heaves upward, the seawater in the receiving groove will flow out of the first spoiler holes in the reverse direction, thereby providing a certain amount of damping and further reducing the heaving amplitude of the wind power foundation, thus further improving the stability of the wind power foundation and having a better anti-overturning effect.

[0024] Reference is made below to Figures 1 to 9 describe a floating wind power foundation and a wind power device according to an embodiment of the present invention.

[0025] Reference Figures 1 to 9 As shown, the floating wind power foundation according to the first aspect embodiment of the present invention includes at least one floating body unit 100. Specifically, it may include one, two, three, six or other appropriate numbers of floating body units 100, which are determined according to the power, weight, etc. of the wind turbine 500. For example, when a small-power wind turbine 500 is used, only one floating body unit 100 may be provided, and when a large-power wind turbine 500 is used, multiple floating body units 100 may be provided. The floating body unit 100 includes an annular floating body 110 and a heave plate assembly 120.

[0026] Among them, the annular floating body 110 is annular. The projection of the outer peripheral wall of the annular floating body 110 in the vertical direction may be triangular, and the projection of the inner peripheral wall of the annular floating body 110 in the vertical direction may also be triangular. In this case, the annular floating body 110 may include three rectangular floating boxes connected end to end. Of course, in some other embodiments of the present invention, the annular floating body 110 may also be circular, etc., which will not be elaborated here.

[0027] The heave plate assembly 120 includes at least two heave plates 121 arranged one above the other. Specifically, it may include two, three, four or other appropriate numbers of heave plates 121. For example, it may be two heave plates 121. The plate surface of the heave plate 121 may be horizontally arranged, that is, the thickness direction of the heave plate 121 is the vertical direction. The heave plate 121 may be made of fiberglass, that is, made of FRP material. Fiberglass has high strength and stiffness, is light in texture, and has good corrosion resistance. Of course, the heave plate 121 may also be made of other appropriate materials, such as steel, etc., which will not be elaborated here.

[0028] The heave plate 121 is provided with a plurality of first spoiler holes 122, and the first spoiler holes 122 penetrate the heave plate 121 along the thickness direction of the heave plate 121. Reference is made to Figure 6As shown, the first spoiler holes 122 of two adjacent damping plates 121 are vertically offset, that is, the projections of the first spoiler holes 122 of two adjacent damping plates 121 in the vertical direction do not overlap. The uppermost damping plate 121 is connected to the annular floating body 110. For example, the outer peripheral wall of the uppermost damping plate 121 can be connected to the bottom end of the inner peripheral wall of the annular floating body 110, or the edge of the upper surface of the uppermost damping plate 121 can be connected to the bottom surface of the annular floating body 110. An accommodation groove 123 is formed by enclosing between the upper surface of the damping plate 121 and the inner peripheral wall of the annular floating body 110. The first spoiler hole 122 of the uppermost damping plate 121 communicates with the accommodation groove 123.

[0029] In this application, the floating body unit 100 includes at least two damping plates 121 arranged vertically. Compared with a single damping plate 121, it exerts a greater damping on seawater. Moreover, each damping plate 121 is provided with a first spoiler hole 122, and the first spoiler holes 122 of two adjacent damping plates 121 are vertically offset. In this way, when the seawater causes heaving to the wind power foundation, part of the seawater will flow through the first spoiler holes 122 of multiple damping plates 121 in sequence, thereby changing the flow direction of the seawater, making the seawater flow in multiple directions instead of completely flowing vertically, and also increasing the flow path, effectively disturbing the vertical flow of the seawater, exerting a greater additional damping on the heaving motion of the wind power foundation, and reducing the heaving motion amplitude and motion frequency of the wind power foundation.

[0030] In addition, the uppermost damping plate 121 is connected to the annular floating body 110, and an accommodation groove 123 is formed by enclosing between the uppermost damping plate 121 and the inner peripheral wall of the annular floating body 110. When the annular floating body 110 is partially submerged in the sea, seawater will enter the accommodation groove 123 through the first spoiler hole 122. When the wind power foundation shakes and heaves, the seawater in the accommodation groove 123 cannot quickly flow out from the first spoiler hole 122. Therefore, the seawater in the accommodation groove 123 can also play a certain ballast role, reducing the shaking and heaving amplitude of the wind power foundation. In addition, when the wind power foundation heaves upward, the seawater in the accommodation groove 123 will flow out of the first spoiler hole 122 in the reverse direction, thereby being able to exert a certain damping and further reducing the heaving amplitude of the wind power foundation, so as to further improve the stability of the wind power foundation and have a better anti-overturning effect.

[0031] Reference Figure 4 and Figure 5As shown, in some embodiments of the present invention, a plurality of rib plates 124 are provided between two adjacent anti-rolling plates 121. The rib plates 124 are provided with a plurality of second spoiler holes 125, and the second spoiler holes 125 penetrate the rib plates 124 along the thickness direction of the rib plates 124. For example, the plate surface of the rib plate 124 can be vertically arranged, that is, the thickness direction of the rib plate 124 is the horizontal direction. The rib plate 124 can be prepared from fiberglass, that is, prepared from FRP material. Of course, the rib plate 124 can also be prepared from other suitable materials, such as steel, which will not be elaborated here.

[0032] In this embodiment, a plurality of rib plates 124 are provided between two adjacent anti-rolling plates 121. In this way, not only can the structural strength of the anti-rolling plate assembly 120 be improved, the stiffness and overall stability of the anti-rolling plate assembly 120 be increased, but also additional damping can be applied to the lateral and longitudinal flows of seawater. At the same time, the rib plates 124 are provided with a plurality of second spoiler holes 125, so that the lateral and longitudinal flow modes of seawater can be changed, enabling seawater to flow in multiple directions instead of completely flowing in the lateral and longitudinal directions, and also increasing the flow path. Furthermore, the lateral and longitudinal flows of seawater can be effectively disturbed, a greater additional damping can be applied to the rolling and pitching motions of the wind power foundation, and the amplitudes and motion frequencies during the rolling and pitching of the wind power foundation can be reduced, comprehensively improving the stability of the wind power foundation.

[0033] Reference Figure 4 As shown, in some embodiments of the present invention, the plurality of rib plates 124 are divided into two groups. The rib plates 124 in the same group are parallel to each other, and the rib plates 124 in different groups are cross-connected, and the thickness directions of the rib plates 124 in different groups can be perpendicular to each other. The rib plates 124 in the same group can include two, three, four or other appropriate numbers of rib plates 124. For example, the same group can include two rib plates 124.

[0034] In this embodiment, with such a setting, not only can the structural strength of the anti-rolling plate assembly 120 be further improved, the stiffness and overall stability of the anti-rolling plate assembly 120 be further increased, but also the lateral and longitudinal flows of seawater can be further disturbed, a greater additional damping can be applied to the rolling and pitching motions of the wind power foundation, and the motion amplitudes and motion frequencies of the rolling and pitching of the wind power foundation can be further reduced.

[0035] In some embodiments of the present invention, among the rib plates 124 in the same group, the second spoiler holes 125 of two adjacent rib plates 124 are arranged in a staggered manner along the thickness direction of the rib plates 124 in this group. In this embodiment, with such a setting, when the lateral and longitudinal flows of seawater cause rolling and pitching of the wind power foundation, the spoiler effect on the lateral and longitudinal flows of seawater is better, the rolling and pitching amplitudes can be further reduced, and the stability is better.

[0036] Reference Figure 2As shown, in some embodiments of the present invention, the annular floating body 110 includes an annular outer pipe 111, an annular inner pipe 112, and a first concrete layer 113. The annular inner pipe 112 is disposed inside the annular outer pipe 111 and extends along the length direction of the annular outer pipe 111. The first concrete layer 113 is filled between the annular outer pipe 111 and the annular inner pipe 112.

[0037] In this embodiment, the annular floating body 110 adopts a composite structure combining the annular outer pipe 111, the first concrete layer 113, and the annular inner pipe 112. The annular outer pipe 111 and the annular inner pipe 112 can effectively restrain and protect the first concrete layer 113, reducing the loosening and corrosion of the first concrete layer 113. Moreover, the annular outer pipe 111 and the annular inner pipe 112 are supported by the first concrete layer 113, and when subjected to the impact of seawater, they can reduce deformation and fracture. In addition, the annular inner pipe 112 is covered by the first concrete layer 113 and will not be exposed outside, with higher fatigue strength and longer fatigue life. Therefore, the annular floating body 110 of the present application has excellent strength, stiffness, and service life, and compared with all-steel structures, it uses less steel and has lower costs.

[0038] It should be noted that both the annular outer pipe 111 and the annular inner pipe 112 can be made of fiberglass. Fiberglass has high strength and stiffness, is lightweight, and has good corrosion resistance. In addition, the fibers of fiberglass can more effectively restrain the first concrete layer 113. Of course, the annular outer pipe 111 and the annular inner pipe 112 can also be made of other materials, such as steel.

[0039] Reference Figure 2 As shown, in some embodiments of the present invention, a plurality of annular reinforcing pipes 114 are arranged side by side at the bottom end inside the first concrete layer 113. The annular reinforcing pipes 114 extend along the length direction of the annular outer pipe 111, and / or a plurality of spiral stirrups 115 are arranged side by side at the top end inside the first concrete layer 113. The spiral stirrups 115 extend along the length direction of the annular outer pipe 111.

[0040] For example, the cross-section in the length direction of the annular floating body 110 can be rectangular. The plurality of annular reinforcing pipes 114 can be arranged from the inside to the outside of the annular floating body 110. The annular reinforcing pipes 114 can be steel pipes or can be made of fiberglass. The plurality of spiral stirrups 115 can be arranged from the inside to the outside of the annular floating body 110. The spiral stirrups 115 can be connected end to end and extend along the length direction of the annular outer pipe 111. The spiral stirrups 115 are spiral in the length direction. The spiral stirrups 115 can be made of steel or fiberglass. The number and spacing of the annular reinforcing pipes 114, as well as the number and spacing of the spiral stirrups 115, can be designed and determined according to the force conditions.

[0041] During the operation of the annular floating body 110, it is subjected to the pressure of the column 200, the tower 400 and the wind turbine 500, as well as the buoyancy of seawater, and may bend downward. In this case, the top of the annular floating body 110 is compressed and the bottom is stretched. In this embodiment, a plurality of spiral steel bars 115 are arranged side by side at the top in the first concrete layer 113. The spiral steel bars 115 can further restrain the top of the first concrete layer 113, improving the anti-deformation ability and anti-fracture ability of the top of the first concrete layer 113. A plurality of annular strengthening pipes 114 are arranged side by side at the bottom in the first concrete layer 113. The annular strengthening pipes 114 have good ductility, can effectively share the tensile force received by the bottom of the first concrete layer 113 and improve the ductility of the bottom of the entire annular floating body 110. At the same time, they can also form a cavity in the first concrete layer 113, further reducing the self-weight of the annular floating body 110.

[0042] Reference Figure 1 、 Figure 3 and Figure 7 As shown in

[0043] In this embodiment, the column 200 adopts a composite structure combining the vertical outer pipe 210, the second concrete layer 230 and the vertical inner pipe 220 arranged in sequence from outside to inside. The vertical outer pipe 210 and the vertical inner pipe 220 can effectively restrain and protect the second concrete layer 230, reducing the loosening and corrosion of the second concrete layer 230. Moreover, the vertical outer pipe 210 and the vertical inner pipe 220 are supported by the second concrete layer 230, and can reduce deformation and fracture when subjected to the impact of sea breeze. In addition, the vertical inner pipe 220 is covered by the second concrete layer 230 and will not be exposed outside, with higher fatigue strength and longer fatigue life. Therefore, the column 200 of this application has excellent strength, stiffness and service life.

[0044] It should be noted that both the vertical outer pipe 210 and the vertical inner pipe 220 can be made of fiberglass. Fiberglass has high strength and stiffness, is light in texture, and has good corrosion resistance. In addition, the fibers of fiberglass can more effectively restrain the second concrete layer 230. Of course, the vertical outer pipe 210 and the vertical inner pipe 220 can also be made of other suitable materials, such as made of steel.

[0045] Reference Figure 2 As shown, in some embodiments of the present invention, the annular inner pipe 112 contains ballast water 116, and the vertical inner pipe 220 communicates with the annular inner pipe 112.

[0046] In this embodiment, the annular inner pipe 112 contains ballast water 116, and the ballast water 116 can play a ballast role, further reducing the heaving and swaying of the wind power foundation and improving the stability of the wind power foundation. In addition, the vertical inner pipe 220 communicates with the annular inner pipe 112, and the vertical inner pipe 220 can communicate with the outside. When the wind power foundation shakes, the ballast water 116 can flow, and the dynamic adjustment of the position of the ballast water 116 can be realized, so that the ballast stability effect is better. In addition, the ballast water 116 can also be supplemented into the annular inner pipe 112 through the vertical inner pipe 220, which is more convenient to use.

[0047] Reference Figure 1 and Figure 7 As shown, in some embodiments of the present invention, a cable 300 is provided between the vertical outer pipe 210 and the annular outer pipe 111. For example, the cable 300 can be made of fiberglass or steel wire rope. One end of the cable 300 can be connected to the upper end of the vertical outer pipe 210, and the other end can be connected to the side of the annular outer pipe 111 away from the vertical outer pipe 210. When there is only one floating body unit 100, the annular outer pipe 111 can be connected with two or more cables 300. When multiple floating body units 100 are provided, each floating body unit 100 can be correspondingly provided with only one cable 300, and the cable 300 can be located on the side where two adjacent floating body units 100 are close to each other.

[0048] In this embodiment, setting the cable 300 can improve the overall structural strength of the wind power foundation and reduce the bending and fracture of the column 200.

[0049] Reference Figure 3 As shown, in some embodiments of the present invention, a plurality of vertical strengthening pipes 240 are provided in the second concrete layer 230, and the plurality of vertical strengthening pipes 240 are arranged along the circumferential direction of the vertical outer pipe 210. For example, the vertical strengthening pipe 240 can be a steel pipe or made of fiberglass, and the vertical strengthening pipe 240 can extend vertically.

[0050] In this embodiment, a plurality of vertical strengthening pipes 240 are provided in the second concrete layer 230. In this way, not only can the structural strength of the column 200 be further improved and the bending or fracture of the column 200 be reduced, but also a cavity can be formed in the second concrete layer 230 to reduce the self-weight of the column 200.

[0051] Reference Figure 7 and Figure 8As shown, in some embodiments of the present invention, the floating body unit 100 includes a plurality of them. The annular floating bodies 110 of the plurality of floating body units 100 are arranged in a circular pattern. Among them, two adjacent annular floating bodies 110 are in contact with each other and detachably connected. For example, as Figure 7 and Figure 8 shown, the floating body unit 100 can be six. The six floating body units 100 are arranged in a circular pattern. The projection of the outer peripheral wall of the annular floating body 110 in the vertical direction can be approximately an equilateral triangle, and two adjacent floating body units 100 are in contact with each other. As Figure 1 shown, docking plates 118 can be provided on both sides of the floating body unit 100. The docking plates 118 can be made of fiberglass or other suitable materials. The docking plates 118 can be provided with connection holes. The docking plates 118 of two adjacent floating body units 100 are in contact, and fastening bolts can be installed in the corresponding connection holes.

[0052] In this embodiment, with such a setting, the anti-heave and anti-rocking effects of the wind power foundation are better, the stability is better, and it can be applied to wind turbines 500 with greater power and weight. In addition, two adjacent annular floating bodies 110 are detachably connected, so that assembly and handling are more convenient.

[0053] It should be noted that, as Figure 9 shown, in some other embodiments of the present invention, when the number of floating body units 100 is small, for example, three, two adjacent annular floating bodies 110 can be arranged at intervals. In this way, two adjacent annular floating bodies 110 can be detachably connected through a connecting portion 117. For example, the connecting portion 117 and the annular floating body 110 can be connected by fasteners or snapped together, etc. In this way, the overall structural strength of the wind power foundation is higher, the stability is also better, and the assembly and handling are also relatively convenient.

[0054] The floating body unit 100 of the present application can be used alone or in combination with multiple ones, which has extremely high flexibility, is convenient for standardized production and customized design, and reduces the production and manufacturing costs.
