Foundation structure for integrated hoisting of wind turbine

Abstract

This invention relates to a foundation structure for the integral hoisting of a wind turbine, comprising a jacket foundation, a docking structure, multiple buffer components, and a main structural component. During integral hoisting, the wind turbine is connected to the upper end of the main structural component. A floating crane is used to lift the main structural component, thereby hoisting the entire wind turbine. The wind turbine, along with its integrally hoisted main structural component, is then hoisted onto the jacket foundation. Since the buffer component is an LMU sandbox, the locator of the main structural component can be aligned with the conical receiver of the buffer component. The locator is then slowly lowered into the corresponding conical receiver to achieve a soft landing of the wind turbine. The sand in the LMU sandbox is then released, allowing the bottom flange of the wind turbine to fully rest on the top flange of the foundation. Finally, the bottom flange of the wind turbine is connected to the top flange of the foundation according to the wind turbine installation manual. This simple integral hoisting foundation structure allows for the rapid completion of the integral hoisting of the wind turbine.

Description

Technical Field

[0001] This invention relates to the field of offshore wind power engineering technology, and in particular to a foundation structure suitable for the integral hoisting of wind turbines. Background Technology

[0002] With the development of China's offshore wind power industry, two technical solutions have emerged for offshore wind turbine installation: split-unit installation and integral installation. Integral installation utilizes floating crane vessels, unaffected by deep water conditions or seabed geological conditions. However, the floating crane vessels used in integral installation are subject to up-and-down movement due to waves and other factors during offshore operations. The challenge of integral installation lies in achieving a smooth connection between the wind turbine and foundation without damaging the turbine or foundation, and ensuring precise alignment of the bolt holes on the bottom flange of the wind turbine tower with the bolt holes on the top flange of the foundation after connection, thus completing the bolted connection installation.

[0003] With the large-scale development of offshore wind farms in deep-sea areas in China, the foundations for wind turbines will mainly be jacket foundations. The integrated hoisting technology for wind turbines can solve the problem of limited water depth for self-elevating wind turbine installation platform vessels, and can provide an effective solution for the hoisting of high-power wind turbines in deep-sea areas.

[0004] The buffer alignment process described in patent document CN215486378U involves using multiple jacks and multiple hydraulic push rods with axial through holes for positioning. The buffer alignment process described in patent document CN202558447U involves six buffer following cylinders and three booms for initial positioning, followed by two pin holes and four cylinders for final positioning. Both of these existing technical solutions and devices suffer from the problem of being unsuitable for the foundation of integral wind turbine hoisting due to the complex structure of the buffer alignment device. Summary of the Invention

[0005] Therefore, it is necessary to provide a foundation structure for the overall hoisting of wind turbines, addressing the problem that existing buffer alignment technology solutions and devices are difficult to apply to the foundation due to the complex structure of the buffer alignment device.

[0006] A foundation structure for an integral hoisting system of a wind turbine, characterized in that the foundation structure for the integral hoisting system of the wind turbine comprises:

[0007] Jacket frame foundation;

[0008] A docking structure is provided on top of the jacket foundation. The docking structure includes a foundation top flange and at least three load-bearing columns. The at least three load-bearing columns are evenly arranged around the foundation top flange and connected to the foundation top flange. The foundation top flange is used to connect to the flange at the bottom of the wind turbine.

[0009] Multiple buffer components, the bottom of which is connected to the top of the supporting column in a corresponding manner, wherein the buffer component is an LMU sandbox; and

[0010] The main structural component has multiple positioners at its lower end, each corresponding to a plurality of buffer components. The positioners are used to position and cooperate with the corresponding buffer components. The upper end of the main structural component is used to connect to the fan.

[0011] Furthermore, the basic structure for the integral hoisting of the wind turbine includes: multiple three-dimensional adjustment components, each of which corresponds to a supporting column;

[0012] The three-dimensional adjustment component includes:

[0013] An adjusting component, wherein the top of the supporting column is connected to the bottom of the adjusting component of the corresponding three-dimensional adjusting assembly;

[0014] A carrier member, the top of which is connected to the bottom of the buffer assembly, and the bottom of which is connected to the top of the adjusting member, so that the adjusting member can adjust the position of the carrier member in a first direction, a second direction, and a third direction; wherein the first direction, the second direction, and the third direction are mutually perpendicular, and the third direction is a vertical direction.

[0015] Furthermore, the top of the supporting column is connected to a first top flange, and the bottom of the adjusting component is connected to a first bottom flange, wherein the first top flange and the first bottom flange are detachably connected.

[0016] Furthermore, the top of the carrier is connected to a second top flange, and the bottom of the buffer assembly is connected to a second bottom flange, with the second top flange and the second bottom flange being detachably connected.

[0017] Furthermore, the adjusting component is a three-dimensional jack, which is equipped with an X cylinder, a Y cylinder, and a Z cylinder to move the bearing component along the first direction, the second direction, and the third direction, respectively.

[0018] Furthermore, multiple three-dimensional adjustment components are connected to the control system so that the control system can adjust the multiple three-dimensional adjustment components in a coordinated manner.

[0019] Furthermore, the jacket foundation includes:

[0020] At least three supporting uprights, each corresponding to a load-bearing column;

[0021] Multiple structural rods, wherein at least three supporting uprights are connected and supported by the multiple structural rods.

[0022] Furthermore, the at least three supporting uprights are detachably connected to the plurality of structural rods, the supporting uprights are detachably connected to the corresponding load-bearing columns, and the load-bearing columns are detachably connected to the corresponding foundation top flange.

[0023] Furthermore, there are four supporting poles.

[0024] Furthermore, the lower end of the foundation top flange is used to connect to a monopile foundation.

[0025] The aforementioned foundation structure for the integral hoisting of the wind turbine involves connecting the wind turbine to the upper end of the main structural component during the integral hoisting process. A floating crane is used to lift the main structural component, thereby hoisting the wind turbine. Subsequently, the wind turbine, along with its integrally hoisted main structural component, is hoisted onto the jacket foundation. Since the buffer assembly is an LMU sandbox, the locator of the main structural component can be aligned with the conical receiver of the buffer assembly. The locator is then slowly lowered into the corresponding receiver to achieve a soft landing of the wind turbine. The sand in the LMU sandbox is released, allowing the receiver of the main structural component, supported by the locator, to slowly descend into the LMU sandbox with the flowing sand until the main structural component contacts the outer sleeve of the LMU sandbox. This ensures that the bottom flange of the wind turbine is fully positioned on the top flange of the foundation. The connection between the bottom flange of the wind turbine and the top flange of the foundation is performed according to the requirements of the wind turbine installation manual. Therefore, the aforementioned foundation structure for the integral hoisting of the wind turbine achieves rapid wind turbine hoisting through a simple structural design. Attached Figure Description

[0051] An embodiment of the present invention provides a basic structure for the integral hoisting of a wind turbine, including a jacket foundation 120, a docking structure 110, multiple buffer components 150, and a main structural component 130.

[0052] The docking structure 110 is located on top of the jacket foundation 120. The docking structure 110 includes a foundation top flange 112 and at least three load-bearing columns 111. The at least three load-bearing columns 111 are evenly arranged around the foundation top flange 112 and connected to it. The foundation top flange 112 is used to connect to the flange at the bottom of the fan 210. The bottom of each buffer assembly 150 is connected to the top of one of the load-bearing columns 111. The buffer assembly 150 is an LMU sandbox. The lower end of the main structural member 130 is provided with multiple positioners 160, each corresponding to one of the buffer assemblies 150. The positioners 160 are used for positioning and engaging with their respective buffer assemblies 150. The upper end of the main structural member 130 is used to connect to the fan 210.

[0053] In actual use, the aforementioned integrated wind turbine mounting foundation structure has a jacket-type foundation 120 positioned at the pre-installation location of the wind turbine 210. Since the docking structure 110 is located on top of the jacket-type foundation 120, the jacket-type foundation 120 can support the docking structure 110. Because the docking structure 110 includes a top flange 112 for connection to the flange at the bottom of the wind turbine 210, the docking structure 110 can also support the wind turbine 210.

[0054] Since the docking structure 110 includes at least three supporting columns 111, which are evenly arranged around and connected to the base top flange 112, the pressure from the fan 210 on the base top flange 112 can be evenly transmitted to each supporting column 111. This results in a uniform distribution of the supporting force on the base top flange 112, thus stably supporting the fan 210 structure connected to it. The bottom of the buffer assembly 150 is connected to the top of the supporting column 111, and the upper end of the main structural member 130 is used to connect to the fan 210. Since the lower end of the main structural member 130 is provided with multiple positioners 160 corresponding to the multiple buffer assemblies 150, when the fan 210 is installed to the docking structure, the positioners 160 are positioned and engaged with the corresponding buffer assembly 150, so that the fan 210 is accurately docked with the docking structure 110. Since the buffer assembly 150 is an LMU sandbox, the receiver 151 at the top of the LMU sandbox can cooperate with its corresponding locator 160 to achieve positioning during the docking process of the wind turbine 210. Moreover, the lateral elastic buffer pads (not shown) and vertical elastic buffer pads (not shown) inside the LMU sandbox buffer the impact force during the docking of the wind turbine 210.

[0055] The LMU (Leg Mating Unit) sandbox has a sleeve structure. The outermost layer is a steel pipe, and the interior includes a conical receiver 151, a sandbox, vertical buffer pads, and elastic buffer pads. The conical receiver 151 acts as a guide, capturing the movement of the locator 160 and ensuring that the locator 160 accurately aligns with the conical receiver 151 and falls smoothly into it, achieving load transfer. The vertical and horizontal buffer pads respectively buffer the loads during vertical and horizontal collisions. The LMU sandbox not only avoids rigid collisions when the main structural member 130 and the supporting column 111 are joined, but also allows for sand discharge to adjust the relative positions of the main structural member 130 and the supporting column 111 if necessary. The specific structure of the LMU sandbox is based on existing technology.

[0056] See Figure 7 , Figure 9 ,and Figure 10During the overall hoisting of the wind turbine 210, the wind turbine is connected to the upper end of the main structural component 130. A floating crane is used to lift the main structural component 130, thereby lifting the wind turbine 210. Subsequently, the wind turbine, along with its overall hoisted main structural component 130, is hoisted above the jacket foundation 120. Since the buffer assembly 150 is an LMU sandbox, the positioner 160 of the main structural component 130 can be aligned with the conical receiver 151 of the buffer assembly 150. The positioner 160 is then slowly lowered into the corresponding receiver 151 to complete the soft landing of the wind turbine. The sand in the LMU sandbox is released, allowing the receiver 151, which is supported by the positioner 160, to slowly descend into the LMU sandbox as the sand flows out, until the main structural component 130 contacts the outer sleeve of the LMU sandbox, thereby allowing the bottom flange of the wind turbine to completely fall onto the top flange 112 of the foundation. Connect the flange at the bottom of the fan (not shown in the figure) to the top flange 112 of the foundation according to the requirements of the fan installation manual. It can be seen that the foundation structure for the above-mentioned integral fan hoisting achieves rapid hoisting of the fan 210 through a simple structural design.

[0057] In one embodiment, the number of supporting columns 111 is four.

[0058] In other embodiments, the supporting columns 111 may be three, five, six, etc.

[0059] In one embodiment, the top flange 112 of the foundation is provided with bolt holes, and the flange at the bottom of the fan is provided with bolt holes. The bolt holes of the top flange 112 of the foundation correspond one-to-one with the bolt holes of the flange at the bottom of the fan, and the top flange 112 of the foundation is connected to the flange at the bottom of the fan by bolts.

[0060] In one embodiment, the foundation structure for the integral hoisting of the wind turbine includes multiple three-dimensional adjustment components 140, each corresponding to a supporting column 111. Each three-dimensional adjustment component 140 includes an adjustment element 142 and a supporting element 141. The top of the supporting column 111 is connected to the bottom of the corresponding adjustment element 142 of the three-dimensional adjustment component 140. The top of the supporting element 141 is connected to the bottom of a buffer component 150, and the bottom of the supporting element 141 is connected to the top of the adjustment element 142, so that the adjustment element 142 adjusts the position of the supporting element 141 in a first direction XX', a second direction YY', and a third direction ZZ'. The first direction XX', the second direction YY', and the third direction ZZ' are all perpendicular to each other, with the third direction ZZ' being a vertical direction.

[0061] Because the top of the supporting column 111 is connected to the bottom of the adjusting component 142 of the corresponding three-dimensional adjusting component 140, and the top of the supporting component 141 is connected to the bottom of the buffer component 150, and the bottom of the supporting component 141 is connected to the top of the adjusting component 142, after the bottom flange of the fan is completely placed on the top flange of the foundation 112, the corresponding buffer components 150 can be lifted along the third direction ZZ' by multiple three-dimensional adjusting components 140, thereby lifting the fan 210. Then, according to the deviation between the bolt holes of the bottom flange of the fan 210 and the bolt holes of the top flange of the foundation 112, the position of the fan 210 is adjusted along the first direction XX' and the second direction YY' by the three-dimensional adjusting components 140, so that the bolt holes of the bottom flange of the fan and the bolt holes of the top flange of the foundation 112 are aligned. Then, the bolt holes of the top flange of the foundation 112 can be matched one by one with the bolt holes of the bottom flange of the fan, and the bottom flange of the fan can be connected to the top flange of the foundation 112 by bolts, thereby completing the hoisting of the fan 210.

[0062] In one embodiment, the top of the supporting column 111 is connected to a first top flange 113, and the bottom of the adjusting member 142 is connected to a first bottom flange 143. The first top flange 113 and the first bottom flange 143 are detachably connected, so that the supporting column 111 and the bottom of the adjusting member 142 can be detachably connected. This allows the adjusting member 142 to be moved horizontally relative to the supporting column 111, so that the three-dimensional adjusting assembly 140 can be disassembled, facilitating the reuse of the three-dimensional adjusting assembly 140.

[0063] In one embodiment, the top of the carrier 141 is connected to a second top flange 144, and the bottom of the buffer assembly 150 is connected to a second bottom flange 152. The second top flange 144 and the second bottom flange 152 are detachably connected, so the buffer assembly 150 can be detachably connected to the top of the carrier 141. This allows the buffer assembly 150 to be moved horizontally relative to the carrier 141, so that the buffer assembly 150 can be disassembled and reused.

[0064] Since the adjusting component 142 can be moved horizontally relative to the supporting column 111 and the buffer component 150 can be moved horizontally relative to the supporting component 141, the three-dimensional adjusting component 140 can be moved and disassembled horizontally after the wind turbine 210 is hoisted, thereby making room for the buffer component 150 to move along the third direction ZZ', so that the three-dimensional adjusting component 140 and the buffer component 150 can be reused after disassembly, thereby reducing the hoisting cost of the wind turbine 210.

[0065] In one embodiment, the adjusting member 142 is a three-dimensional jack, which is equipped with an X cylinder 145, a Y cylinder 146, and a Z cylinder 147. This allows the bearing member 141 to be detachably connected to the Z cylinder 147, so that the bearing member 141 can move along the first direction XX', the second direction YY', and the third direction ZZ', respectively. After the fan is in place, the fan 210 is lifted by the Z cylinder 147, and the bottom flange bolt holes of the fan 210 and the top flange bolt holes of the foundation are aligned by the X cylinder 145 and the Y cylinder 146.

[0066] In other embodiments, the adjustment member 142 can also be other structures in the prior art, as long as it can adjust the carrier member 141 connected to the top of the adjustment member 142 in the first direction XX', the second direction YY', and the third direction ZZ'.

[0067] In one embodiment, multiple three-dimensional adjustment components 140 are connected to the control system so that the control system can adjust the multiple three-dimensional adjustment components 140 in a coordinated manner, thereby eliminating the need for manual alignment of the bolt holes of the bottom flange of the wind turbine and the bolt holes of the top flange 112 of the foundation, as well as manual operation of the three-dimensional adjustment components 140, reducing working hours and lowering costs.

[0068] The control system can adopt an existing electronic control operating system.

[0069] In another embodiment, the multiple three-dimensional adjustment components 140 are independent of each other, so that any one of the three-dimensional adjustment components 140 can be adjusted individually to ensure that the foundation top flange 112 is accurately aligned with the bottom of the fan.

[0070] In one embodiment, the jacket foundation 120 includes at least three support columns 121 and multiple structural rods 122. The support columns 121 correspond one-to-one with the load-bearing columns 111, thereby providing stable support for the connecting structure 110. The at least three support columns 121 are connected and supported by multiple structural rods 122, thereby increasing the support strength of the jacket foundation 120 and thus stably supporting the wind turbine 210.

[0071] In one embodiment, at least three support poles 121 are detachably connected to multiple structural poles 122, the support poles 121 are detachably connected to the corresponding load-bearing columns 111, and the load-bearing columns 111 are detachably connected to the corresponding foundation top flanges 112. This allows the support poles 121, structural poles 122, load-bearing columns 111, and foundation top flanges 112 to be detachable, facilitating the recycling and reuse of each structure and reducing the cost of hoisting the wind turbine 210.

[0072] In one embodiment, there are four support poles 121, so that the support poles 121 and their corresponding three-dimensional adjustment components 140 form a square, thereby facilitating the establishment of a coordinate system for adjustment in the first direction XX' and the second direction YY' based on the positions of the multiple three-dimensional adjustment components 140, and thus facilitating the alignment of the bolt holes of the bottom flange of the fan and the bolt holes of the top flange 112 of the foundation.

[0073] In one embodiment, the lower end of the foundation top flange 112 is used to connect to the monopile foundation. Therefore, the foundation top flange 112 in the foundation structure for the integral hoisting of the wind turbine can be connected to the monopile foundation before the wind turbine is hoisted as a whole. Since at least three support poles 121 are detachably connected to multiple structural poles 122, the support poles 121 are detachably connected to the corresponding bearing columns 111, and the bearing columns 111 are detachably connected to the corresponding foundation top flange 112, after the hoisting is completed, the buffer assembly 150 and the three-dimensional adjustment assembly 140 are disassembled, the bearing columns 111 and the foundation top flange 112 are disassembled, and the support poles 121 are disassembled. Subsequently, the support poles 121 and the structural poles 122 are disassembled, and finally the foundation top flange 112 is supported by the monopile foundation, and the foundation top flange 112 supports the wind turbine 210. The lower end of the foundation top flange 112 is used to connect to the monopile foundation, which not only allows the foundation structure of the wind turbine integral hoisting to be used for wind turbine installation supported by monopile foundation, but also allows the support pole 121, structural pole 122 and bearing column 111 to be disassembled and reused after the wind turbine 210 is hoisted, further reducing the hoisting cost of the wind turbine 210.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
