Description

Technical Field

[0001] The present subject matter generally relates to segmented rotor blades for a wind turbine, and more particularly to a method of disassembling a segmented blade for a wind turbine, to a disassembly tool configured for disassembling a segmented blade for a wind turbine, and to a rotor blade assembly. Background Art

[0002] Wind energy is considered to be one of the cleanest and most environmentally friendly energy sources currently available, and for this reason, wind turbines have attracted increasing attention. Modern wind turbines typically include a tower, a generator, a gearbox, a nacelle, and one or more rotor blades. The rotor blades capture kinetic energy from the wind using the known airfoil principle, and the kinetic energy is transferred by rotation to turn a shaft that couples the rotor blades to a gearbox, or directly to a generator if a gearbox is not used. The generator then converts the mechanical energy into electrical energy that can be deployed to the utility grid.

[0003] The size of the rotor blades contributes to the energy efficiency of the wind turbine. Specifically, an increase in the size of the rotor blades can increase the energy output of the wind turbine. The economic benefits of increased wind turbine size or rotor blade size must be weighed against the corresponding costs of manufacturing, transporting, assembling or repairing the wind turbine. One strategy for reducing the cost of preforming, transporting and erecting a wind turbine with increased size rotor blades is to manufacture the rotor blades into blade segments. For example, after transporting the individual blade segments to the erection location, the blade segments can be assembled to form the rotor blade.

[0004] During the manufacture of the blade segments, and in particular before the blade segments are transported to the erection location, the blade segments may have been assembled at the blade manufacturing site (e.g. in a blade manufacturing workshop). For example, the blade segments may be assembled to perform finishing operations on the blade surface and / or to test the rotor blade or its components (such as joints between blade segments). However, moving the blade segments relative to each other at the manufacturing site may in particular entail a risk of injury to personnel operating at the manufacturing site and / or a risk of damaging the blade segments.

[0005] Therefore, the present disclosure is directed to a method of disassembling a segmented blade for a wind turbine, a disassembly tool and a rotor blade assembly which may provide for safe, fast and / or cost-effective disassembly of a segmented blade for a wind turbine.

[0021] Reference will now be made in detail to embodiments of the present invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of illustration of the present invention without limiting the present invention. In fact, it will be clear to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the present invention. For example, a feature shown or described as a part of an embodiment can be used in conjunction with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover such modifications and variations as fall within the scope of the appended claims and their equivalents.

[0022] Figure 1 A modern upwind wind turbine 2 is shown having a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor shaft. The rotor comprises a hub 8 and at least one rotor blade 10 extending radially from the hub 8, each blade 10 having a blade root 16 closest to the hub 8 and a blade tip 14 farthest from the hub 8. For example, Figure 1 As shown in FIG, the rotor may include three rotor blades 10 .

[0023] Figure 2A schematic diagram of a segmented blade 10 for a wind turbine 2 is shown in an assembled state of the segmented blade 10. The segmented blade 10 comprises a root region 24 closest to the hub 8, an airfoil region 28 farthest from the hub 8, and a transition region 26 between the root region 24 and the airfoil region 28. The blade 10 comprises a leading edge 18 facing the direction of rotation of the blade 10 when the blade 10 is mounted to the hub 8, and a trailing edge 20 facing in the opposite direction of the leading edge 18.

[0024] The airfoil region 28 (or profile region) has a blade shape for generating lift, while the root region 24 may have a substantially circular or elliptical cross section due to structural considerations, which, for example, makes it easier and safer to mount the blade 10 to the hub 8. The diameter (or chord) of the root region 24 may be substantially constant along the entire root region 24. The transition region 26 has a transition profile that gradually changes from the circular or elliptical shape of the root region 24 to the airfoil profile of the airfoil region 28. The chord length of the transition region 26 typically increases with increasing distance from the hub 8. The airfoil region 28 has an airfoil profile having a chord extending between the leading edge 18 and the trailing edge 20 of the blade 10. The width of the chord decreases with increasing distance from the hub 8. The shoulder 30 of the blade 10 is defined as the position where the blade 10 has its maximum chord length. The shoulder 30 is typically provided at the boundary between the transition region 26 and the airfoil region 28.

[0025] According to an embodiment of the present disclosure, the segmented blade 10 includes at least two segments, including a first segment 40 and a second segment 50. The segmented blade 10 may include exactly two segments. For example, Figure 2 The first segment 40 and the second segment 50 are shown joined at the segmentation line 32 of the segmented blade 10. In other embodiments, the segmented blade may include more than two segments, such as exactly three segments or exactly four segments. The segmented blade 10 may extend along the longitudinal axis 34 of the segmented blade 10 in the span direction from the blade root 16 of the segmented blade 10 to the blade tip 14 of the segmented blade 10.

[0026] In an embodiment, the first segment 40 is a root-side segment of the segmented blade 10, and the second segment 50 is a tip-side segment of the segmented blade 10. Specifically, the second segment 50 may be coupled to the first segment 40 such that the second segment 50 extends from the first segment 40 toward the blade tip 14 of the segmented blade 10. In some embodiments, the first segment 40 is a root segment of the segmented blade 10. Specifically, the first segment 40 may include the blade root 16 of the segmented blade 10. The first segment 40 may be configured to be connected to the rotor hub 8. In some embodiments, the second segment 50 is a tip segment including the blade tip 14. For example, Figure 2 The first segment 40 is shown as a root segment, and the second segment 50 is shown as a tip segment.

[0027] According to an embodiment, the first segment 40 and the second segment 50 may be connected via a blade joint to provide a segmented blade 10 in an assembled state. The second segment 50 includes a connecting part 54, which extends into the first segment 40 in the assembled state of the segmented blade 10. In the assembled state, the first shell 42 of the first segment 40 may at least substantially surround at least a portion of the connecting part 54 in a circumferential direction around the longitudinal axis 34. The first shell 42 of the first segment 40 may in particular provide an outer skin of the first segment 40. The second shell 52 of the second segment 50 may provide an outer skin of the second segment 50. In the airfoil region 28 of the segmented blade 10, the first shell 42 and the second shell 52 together may in particular provide an aerodynamic surface of the segmented blade 10 to generate lift. For example, Figure 2 As shown in FIG. 1 , in the assembled state, the first shell 42 and the second shell 52 may abut at the dividing line 32. In the disassembled state of the segmented blade 10, the connecting member 54 may extend beyond the second shell 52, in particular in the direction along the longitudinal axis 34, more particularly in the direction toward the blade root 16.

[0028] In some embodiments, the first segment 40 includes a receiver 44. The receiver 44 may include a receiving space 45 for receiving the connecting member 54 of the second segment 50. The receiver 44 may be disposed within the first shell 42 of the first segment 40.

[0029] According to an embodiment, the connecting member 54 comprises a beam extending in the direction of the longitudinal axis 34. In particular, the connecting member 54 may comprise an extension of a structural member of the second segment 50 beyond the second shell 52. The connecting member 54 may in particular comprise an extension of a spar cap of the second segment 50 and / or an extension of a shear web of the second segment 50. For example, the connecting member 54 may be an extended spar beam of the second segment 50, the spar beam in particular comprising an extended spar cap and an extended shear web. In an embodiment, the connecting member 54 is configured to be inserted into the receiving space 45 of the receiver 44 of the first segment 40.

[0030] According to some embodiments, the first segment 40 and the second segment 50 may be connected via a pin joint. Specifically, each of the connecting member 54 and the receiver 44 may include one or more pin holes. In the assembled state, the connecting member 54 may be locked relative to the receiver 44 via a pin 48 passing through the pin holes of the connecting member 54 and the receiver.

[0031] For example, Figure 3A and 3B Schematically shows an assembly state ( Figure 3A ) and disassembly state ( Figure 3B ) in which the longitudinal axis 34 and the chord-wise direction 36 are located Figure 3A and 3B in the plane. Figure 3A and 3B The joint components of the segmented blade 10 are particularly shown, while other blade components are not shown for the sake of clarity. In the assembled state, the second shell 52 of the second segment 50 is adjacent to the first shell 42 of the first segment 40. The connecting member 54 of the second segment 50 (at Figure 3A and 3B The extended spar cross beam of the second segment 50 in the figure extends into the receiving space 45 of the receiver 44 of the first segment 40. Figure 3A In the embodiment, the first segment 40 and the second segment 50 are locked in place by a pin 48 inserted through the pin hole 46 of the receiver 44 and through the pin hole 56 of the connecting member 54. Alternatively or in addition, in other embodiments, the first segment and the second segment may be locked in place by a connection other than a pin joint, such as via a flange connection or a bolt connection. In still other embodiments, the second segment may include more than one connecting member extending into the first segment in the assembled state of the segmented blade.

[0032] exist Figure 3B , the segmented blade 10 is shown in a disassembled state, wherein the second segment 50 is completely removed from the first segment 40. In particular, the second segment 50 is removed from the first segment 40 in an axial direction. The term "axial" as used herein refers in particular to the longitudinal axis 34 of the segmented blade.

[0033] During the manufacture of the segmented blade, the first segment and the second segment may be assembled, for example, to test the joint between the first segment and the second segment, or, for example, to finish the skin of the segmented blade at the segmented blade's dividing line. Before transporting the segmented blade, the segmented blade may be disassembled again by separating the first segment and the second segment. Specifically, the second segment may be moved in an axial direction relative to the first segment to remove the connecting component from the first segment. When separating the first segment and the second segment, one or both segments may swing relative to the other segment, especially when a crane (such as a bridge crane in a manufacturing workshop) is used to separate the segments. The swinging of one or more segments may damage the segments or cause personal injury. Manual intervention by an operator may reduce or prevent the swinging, however, this may put the operator at risk of injury. Therefore, it may be beneficial to reduce or avoid manual intervention when removing the connecting component to reduce the risk of personal injury and / or reduce the risk of damage to equipment or blade segments during the disassembly of the segmented blade. In addition, in particular considering the demand for cranes and space at the manufacturing site, it may be necessary to perform the disassembly in a fast and / or cost-effective manner.

[0034] Methods and disassembly tools according to embodiments of the present disclosure may in particular reduce the mobility of the second segment of a segmented blade during disassembly of the segmented blade, for example to reduce the risk of injury and / or risk of damage to the blade segment or equipment.

[0035] Figure 4 A flow chart of a method 100 for disassembling a segmented blade 10 for a wind turbine 2 is shown. According to an embodiment, the method 100 comprises providing (block 110) a segmented blade 10 in an assembled state. The segmented blade 10 may be constructed according to the embodiments described herein. In the assembled state, the connecting part 54 of the second segment 50 extends into the first segment 40. The first segment 40 and the second segment 50 may be manufactured separately before assembling the segmented blade 10. The segmented blade 10 may be provided in an assembled state at a manufacturing site, in particular before transporting the first segment 40 and the second segment 50 to an erection site of the wind turbine 2.

[0036] According to some embodiments, the segmented blade 10 may be provided in an at least substantially horizontal orientation in an assembled state. In particular, the longitudinal axis 34 of the segmented blade 10 may be oriented at least substantially horizontally. The terms "horizontal", "vertical", "up", "down", "above", "below", "top" or "bottom" should be understood in particular with respect to gravity. In some embodiments, the chord of the segmented blade 10 may be oriented at least substantially vertically. For example, the leading edge 18 may point in a downward direction, and the trailing edge 20 may point in an upward direction.

[0037] In an embodiment, providing the segmented blade 10 includes holding the segmented blade 10 using one or more holding devices. The one or more holding devices may be configured to move a segment of the segmented blade 10 relative to another segment. Specifically, a first holding device 98 (such as a blade support vehicle) may be used to hold the first segment 40. A second holding device 96 may be used to hold the second segment 50. For example, the second holding device 96 may include a crane, such as a bridge crane at a manufacturing site, particularly a bridge crane at a manufacturing shop. The second holding device 96 may include a connecting device to connect the second segment 50 to a crane hook of the bridge crane.

[0038] According to an embodiment, the method 100 includes partially removing the connection member 54 from the first segment 40 (block 120). Specifically, the second segment 50 may be moved relative to the first segment 40, in particular, away from the first segment 40 in an axial direction. For example, the second holding device 96, such as a bridge crane, may be used to move the second segment 50. In an embodiment, removing the connection member 54 includes exposing a first region 58 of the connection member 54. The first region 58 may be exposed such that the first region 58 is accessible from the outside of the segmented blade 10. The first region 58 may be exposed such that the first region 58 is accessible axially between the first shell 42 of the first segment 40 and the second shell 52 of the second segment 50. The first region 58 may be an axial region of the connection member 54.

[0039] According to an embodiment of the present disclosure, a disassembly tool 60 configured for disassembling the segmented blade 10 is provided. In an embodiment, the disassembly tool 60 includes a tool base 66, which is positioned below the connecting member 54 while the connecting member 54 is removed from the first segment 40, particularly after the connecting member 54 has been partially removed from the first segment 40 and before the connecting member 54 is completely removed from the first segment 40.

[0040] According to an embodiment, the removal tool 60 includes a guide device 80 connected to the tool base 66. The guide device 80 may include a top portion 82 configured to be positioned above the connecting member 54. The top portion 82 may be positioned above the connecting member 54 to limit the mobility of the connecting member 54 while the connecting member 54 is removed from the first segment 40, particularly to limit the mobility of the connecting member 54 in an upward direction.

[0041] In an embodiment, the disassembly tool 60 is configured to move on a support surface 12, such as a floor, for example, a floor of a manufacturing workshop. For example, the disassembly tool 60 may include wheels 72 for moving the disassembly tool 60, the wheels 72 being particularly connected to the tool base 66, particularly at the bottom of the tool base 66. The disassembly tool 60 may further include a brake for braking the wheels. The guide device 80 may be positioned on top of the tool base 66.

[0042] In an embodiment, the method 100 includes positioning (block 130) the disassembly tool 60, particularly after the connection member 54 is partially removed from the first segment 40. The tool base 66 may be positioned below the connection member 54. The top portion 82 of the guide device 80 is positioned in the first zone 58 and above the connection member 54 to limit the mobility of the connection member 54, particularly to limit the mobility of the connection member 54 in the vertical direction and more particularly in the upward direction. More specifically, the top portion 82 of the guide device 80 may be positioned vertically directly above the connection member 54. The top portion 82 may be positioned in a vertical zone between the connection member 54 and the upper end of the first shell 42. In some embodiments, the top portion 82 may contact the upper surface of the connection member 54.

[0043] According to some embodiments, the guide device 80 includes a lateral portion 86. The lateral portion 86 may connect the tool base 66 and the top portion 82 of the guide device 80. Specifically, the lateral portion 86 may be arranged in a vertical region from the top portion 82 to the tool base 66. The lateral portion 86 may be connected to each of the top portion 82 and the tool base 66. In an embodiment, the lateral portion 86 is configured to be laterally positioned relative to the connecting member 54 while the connecting member 54 is removed from the first segment 40. The lateral portion 86 may be configured to limit the mobility of the connecting member 54 in a horizontal direction perpendicular to the longitudinal axis 34 of the segmented blade 10.

[0044] In an embodiment, the disassembly tool 60 has a first horizontal axis 62, wherein in particular, when the disassembly tool 60 is positioned, the first horizontal axis 62 is aligned with the longitudinal axis 34 of the segmented blade. The disassembly tool 60 may have a second horizontal axis 64 that is perpendicular to the first horizontal axis 62. The lateral portion 86 may be offset relative to the center of the top portion 82 in the direction of the second horizontal axis 64. Positioning the disassembly tool 60 may include positioning the lateral portion 86 in the first region 58 of the connection member 54 and laterally relative to the connection member 54.

[0045] In some embodiments, the guide device 80 includes a bottom portion 84 that is positioned below the connecting member 54 while the connecting member 54 is removed from the first segment 40. The bottom portion 84 can be particularly configured to limit the mobility of the connecting member 54 in a downward direction while removing the connecting member 54. Positioning the removal tool 60 can include positioning the bottom portion 84 of the guide device 80 in the first region of the connecting member 54 and below the connecting member 54.

[0046] In some embodiments, positioning the removal tool 60 comprises immobilizing the removal tool 60, in particular after positioning the tool base 66 and / or the guide 80. The removal tool 60 may be immobilized in particular by braking the wheels 72 of the removal tool 60, in particular using brakes for the wheels 72 of the removal tool 60.

[0047] Figure 5A -B shows a schematic diagram of an embodiment of a disassembly tool 60 for disassembling a segmented blade 10, comprising a first segment 40 (particularly a root segment) and a second segment 50 (particularly a tip segment). The first segment 40 and the second segment 50 are held by a holding device (not shown) as described herein. Figure 5A -B shows the segmented blade 10 after the connecting member 54 has been partially removed (block 120) from the first segment 40 and after the disassembly tool 60 has been positioned (block 130). More specifically, Figure 5A A view on one of the pressure side or the suction side of a segmented blade 10 is shown. Figure 5B A view along the longitudinal axis 34 toward the blade tip 14 is shown, wherein the first segment 40 is not shown for clarity. Figure 5A , the second segment 50 is positioned relative to the first segment 40 so that the connecting member 54 is partially removed from the first segment 40 and the first region 58 of the connecting member 54 is exposed. The disassembly tool 60 includes a tool base 66, which is positioned below the connecting member 54 and on the support surface 12, in particular, the floor of the manufacturing site. The disassembly tool 60 is further positioned so that a guide device 80 of the disassembly tool 60 is positioned in the first region 58. Specifically, a top portion 82 of the guide device 80 is positioned above the connecting member 54, a bottom portion 84 is positioned below the connecting member 54, and a lateral portion 86 is positioned laterally relative to the connecting member 54. The guide device 80 limits the mobility of the connecting member 54 in the upward direction, in the downward direction, and in the lateral direction.

[0048] In an embodiment, the method 100 includes completely removing the connection component 54 from the first segment 40 (block 140) after positioning the disassembly tool 60. The connection component 54 may be removed from the first segment 40 in an axial direction, specifically moving the connection component 54 outside the first segment 40. For example, the connection component 54 may be removed from the receiver 44 of the first segment 40 and / or from the first shell 42 of the first segment 40.

[0049] After the connection member 54 is completely removed from the first segment 40, the mobility of the connection member 54 is limited by the disassembly tool 60, in particular, by the guide device 80. The guide device 80 can guide the connection member 54 after the connection member 54 is removed from the first segment 40. In some embodiments, completely removing the connection member 54 from the first segment 40 includes sliding the connection member 54 along the top portion 82 of the guide device 80. In other embodiments, the connection member 54 can slide along the top portion 82, the bottom portion 84 and / or the side portion 86 of the guide device 80. The guide device 80 can avoid or reduce the swinging movement of the connection member 54 or the second segment 50. In particular, the guide device 80 can limit the upward movement, downward movement and / or side movement of the connection member 54. For example, when a crane is used as the second holding device 96 for holding and moving the second segment 50, the swinging movement may occur. Guiding the connection member 54 while separating the segments can particularly reduce the risk of injury or damage during blade disassembly.

[0050] According to some embodiments of the present disclosure, the disassembly tool 60 further includes a support device 90. The support device 90 may be configured to contact the first segment 40 of the segmented blade 10 while removing the connecting member 54 from the first segment 40. In an embodiment, the support device 90 is connected to the tool base 66. Specifically, the support device 90 may be positioned on the tool base 66 and offset relative to the guide device 80 along the first horizontal axis 62 of the disassembly tool 60. The support device 90 may be positioned on the tool base 66, offset relative to the guide device 80 in the vertical direction, in particular, below the guide device 80. The tool base 66 may extend in the direction of the first horizontal axis 62 of the disassembly tool 60 so as to support the guide device 80 and the support device 90.

[0051] In some embodiments, positioning (block 130) the removal tool 60 includes contacting the support device 90 with the first segment 40. Positioning the removal tool 60 may include positioning the support device 90 below the first segment 40 before contacting the support device 90 with the first segment 40. Contacting the support device 90 with the first segment 40 may include applying a force, particularly an upward force, to the first segment 40 using the support device 90. Applying a force to the first segment 40 may clamp the removal tool 60 between the first segment 40 and the support surface 12 on which the removal tool 60 is positioned, particularly for fixing or immobilizing the removal tool 60 relative to the first segment 40.

[0052] For example, Figure 6 A removal tool 60 is shown having a tool base 66 and a guide 80 positioned in the first region 58 of the connection component 54 to guide the connection component 54 during removal according to the embodiments described herein. Figure 6, the disassembly tool 60 further includes a support device 90, which is arranged offset relative to the guide device 80 along the first horizontal axis 62 of the disassembly tool 60 and is lower than the guide device 80. Specifically, the support device 90 is arranged so that during the removal of the connecting component 54 from the first segment 40, the support device 90 can contact the first segment 40 while the guide device 80 guides the connecting component 54.

[0053] Figure 7 Shown according to Figure 6 , but the segmented blade and the disassembly tool 60 after the connecting member 54 has been completely removed from the first segment 40. Figure 7 , the first segment 40 is held by a first holding device 98, in particular a blade bearing vehicle. The second segment 50 is held by a second holding device 96, in particular a bridge crane of a manufacturing workshop. After the connection component 54 is removed from the first segment 40 by moving the second segment 50 away from the first segment 40 in the axial direction, the connection component 54 is still guided by the guide device 80 of the disassembly tool 60. The connection component 54 can slide, for example, along the top portion 82 of the guide device 80, which limits the mobility of the connection component 54 in the upward direction. In particular, the connection component 54 can be prevented from swinging in one or more directions after leaving the first segment 40.

[0054] In an embodiment, the support device 90 includes a lifting device 94 and a contact member 92. The lifting device 94 may be connected to the tool base 66. Specifically, the lifting device 94 may be mounted on or in the tool base 66.
