When environmental conditions are poor, the cable-stayed wind system cannot effectively control the movement of the blades, resulting in poor alignment accuracy and low construction efficiency. Furthermore, in offshore wind power construction with harsh environmental conditions and limited construction space, this method has a short construction window and often fails to meet project schedule requirements.

[0057] Currently, the mainstream installation method for offshore wind power is the single-blade method. The single-blade method refers to lifting the blade using hoisting equipment and special blade lifting tools after the nacelle and hub are installed, using wind to restrict the movement of the blade, and adjusting the crane to achieve the alignment and installation of the blade and hub.

[0058] This blade installation method is significantly limited by environmental conditions. When environmental conditions are poor, the cable-stayed wind system cannot effectively control the movement of the blades, resulting in poor alignment accuracy and low construction efficiency. Furthermore, in offshore wind power construction with harsh environmental conditions and limited construction space, this method has a short construction window and often fails to meet project schedule requirements.

[0059] To address the aforementioned problems, this invention proposes a wind turbine blade installation device and a wind turbine blade alignment and installation method, aiming to provide a wind turbine blade installation device and a wind turbine blade alignment and installation method that can improve the installation alignment accuracy between the blade and the hub. Figures 1 to 8 This is a schematic diagram of an embodiment of the wind turbine blade installation device of the present invention.

[0060] Please refer to Figures 1 to 2 This invention proposes a wind turbine blade installation device 1000, including a fixing part 1 and an alignment device 2. The fixing part 1 is detachably installed onto the tower, facilitating repeated assembly and disassembly of the wind turbine blade installation device 1000. The alignment device 2 includes a clamping part 21, a driving part 22, and a supporting part 23. The clamping part 21 clamps and secures the blade root, restricting its movement and preventing swaying during blade hoisting in extreme weather conditions, thus ensuring the blade root aligns with the tower. The hub is aligned and installed. In addition, the support part 23 is connected to the fixing part 1, and the clamping part 21 is movably installed relative to the support part 23 to facilitate subsequent movement of the clamping part 21. The driving part 22 is used to drive the clamping part 21 to move, so as to realize the alignment and installation of the blade root and the hub. The solution of the present invention, through the cooperation of the fixing part 1 and the alignment device 2, can realize the accurate alignment of the blade root and the hub, and can operate in offshore wind power construction with harsh environmental conditions and limited construction space.

[0061] Specifically, please refer to Figure 3 The fixing part 1 includes a clamping structure 11, which comprises two half-hoops 111. One end of each half-hoop 111 is hinged to the other, and the other end is inserted into each other to define a clamping space for clamping the tower. In some other embodiments, the fixing part 1 may also include a cylindrical mechanism that is inserted into the tower. In this application, the clamping structure 11 is used, and the insertion between the two half-hoops 111 achieves the limiting and clamping effect. Its advantages are that it does not damage the original tower structure, and the clamping force of the clamp is good, providing excellent support and effectively fixing the alignment device 2. Furthermore, the clamping structure 11 is easy to assemble and disassemble, has a robust structure, and can be reused repeatedly.

[0062] It is understood that each of the semi-hoops 111 includes an upper hoop plate 111a, a lower hoop plate 111b, and a plurality of vertical supports 111c connecting the upper hoop plate 111a and the lower hoop plate 111b. The presence of the upper hoop plate 111a and the lower hoop plate 111b in each semi-hoop 111 provides simultaneous support and fixation in both vertical and horizontal directions. In other embodiments, each semi-hoop 111 may also include multiple hoop plates. In this application, for practical application and cost considerations, the upper hoop plate 111a is selected. 11a and the lower hoop plate 111b also provide a good fixing effect. Furthermore, a vertical brace 111c is provided between the upper hoop plate 111a and the lower hoop plate 111b. The vertical brace 111c serves two purposes: firstly, it connects the upper and lower hoop plates 111b; secondly, it increases the strength of the semi-hoop body 111. In embodiments of the present invention, multiple vertical braces 111c are provided to enhance the connection strength between the upper hoop plate 111a and the lower hoop plate 111b, thereby strengthening the fixing strength of the hoop structure 11. Additionally, please refer to... Figure 3 The fixing part 1 further includes a plug-in mating structure 12, which includes a plug-in protrusion and a plug-in recess that plug into each other. A connecting hole is provided in the vertical direction on both the plug-in protrusion and the plug-in recess. A pin 121 is provided in the connecting hole, and the pin 121 is used to fix each of the half-clamps. It is well known that clamps are generally fixed by screws. However, in this application, a rotating shaft is used to fix one end of the half-clamp, and the pin 121 fixes the other end of the half-clamp. This allows for quick assembly and disassembly of the wind turbine blade installation equipment 1000 after the pin 121 is removed, thereby improving construction efficiency and meeting project schedule requirements.

[0063] In addition, to further enhance the fixing effect of the clamping structure 11, the clamping structure 11 also includes a gasket 112. The gasket 112 is disposed on the inner side of the clamping space to fit the tower cylinder. Specifically, the gasket 112 is made of an elastic material, including thermoplastic plastic or rubber. In the actual manufacturing process, the gasket 112 is set with a certain limit of interference fit to increase the friction between the inner side of the clamping structure 11 and the tower cylinder. On the one hand, it can achieve a certain anti-slip effect, and on the other hand, it can also enhance the clamping force of the clamping structure 11 on the tower cylinder, that is, enhance the fixing effect of the clamping system and prevent it from slipping. Furthermore, while improving the fixing effect, the gasket 112 can also play a certain flexible buffering role to avoid damage to the clamping system and the tower cylinder structure.

[0064] Furthermore, the two semi-hoops 111 include an upper hoop plate 111a positioned close to the hub and a lower hoop plate 111b positioned away from the hub. The arc length of the upper hoop plate 111a is less than the arc length of the lower hoop plate 111b. In other words, the arc length enclosed by the upper hoop plate 111a positioned close to the hub is less than the arc length enclosed by the lower hoop plate 111b. This arrangement is to match the shape of the tower, which is narrower at the top and wider at the bottom, so as to achieve a better fixing effect of the clamp structure 11.

[0065] In the embodiments of the present invention, please refer to Figure 4 The clamping part 21 includes a supporting body 211, two clamping teeth 212, and a first linear drive device 214. The supporting body 211 is curved and extended to fit against and support the root of the blade. A rotating shaft is also connected to the supporting body 211, and the rotating shaft is connected to the drive part 22, serving to connect the supporting body 211 and the drive part 22. It is understood that in some embodiments, a gasket 112 is also provided on the side of the supporting body 211 closest to the root of the blade to provide a flexible abutment effect, protecting the blade and the supporting body 211. Furthermore, each clamping tooth 212 is movably disposed at both ends of the supporting body 211 via the clamping rotating shaft, and each clamping tooth 212 has a stroke that moves closer and further away from each other to clamp the root of the blade. Alternatively, it can provide clearance space to allow the blade to detach. The engagement of each clamping tooth 212 can achieve a fastening effect at the root of the blade, preventing the blade from moving during installation. The first linear drive device 214 has a first fixed part and a first movable part that can move relative to each other along a straight line. One of the first fixed part and the first movable part is connected to the support body 211, and the other is connected to the clamping teeth 212 to drive each clamping tooth 212 to move. In an embodiment of the present invention, the first linear drive device 214 is configured as a hydraulic rod. One end of the hydraulic rod is connected to the clamping teeth 212, and the other end of the hydraulic rod is connected to the support body 211. The hydraulic rod can extend and retract to drive the clamping teeth 212 to clamp or release the root of the blade.

[0066] To achieve flexible and precise driving of the clamping part 21 in all directions, the alignment device 2 further includes a first connecting seat 24, a second connecting seat 25, and a third connecting seat 26. The first connecting seat 24 is movably mounted to the support part 23 along a first direction; the second connecting seat 25 is movably mounted to the first connecting seat 24 along a second direction; and the third connecting seat 26 is movably mounted to the second connecting seat 25 along a third direction. The first, second, and third directions are arranged perpendicularly to each other. (Please refer to...) Figure 5 In an embodiment of the present invention, one of the first connecting seat 24, the second connecting seat 25, and the third connecting seat 26 is configured as a movable body, and correspondingly, one of the support part 23, the first connecting seat 24, and the second connecting seat 25 is configured as a fixed body. That is, when the first connecting seat 24 moves relative to the support part 23 along a first direction, the first connecting seat 24 is a movable body and the support seat is a fixed body. When the second connecting seat 25 moves relative to the first connecting seat 24 along a second direction, the second connecting seat 25 is a movable body and the first connecting seat 24 is a fixed body, and so on. The third connecting seat 26 is a movable body and the second connecting seat 25 is a fixed body. It can be understood that the third connecting seat 26 can move relative to the support part 23 along the first direction, the second direction, and the third direction. The clamping part 21 is installed at the third connecting seat 26, thereby realizing a high degree of freedom of movement of the clamping part 21, i.e., the root of the blade.

[0067] Continue to refer to Figure 5 It is understood that the first connecting seat 24 and the support part 23 are connected by a sleeve, and the second connecting seat 25 and the first connecting seat 24 are also connected by a sleeve. With the support part 23 and the first connecting seat 24 as the track, the driving direction can be strictly and precisely controlled, and the connection effect of each connecting platform can be better supported, avoiding slippage during operation and ensuring the sturdiness of the device.

[0068] Furthermore, the drive unit 22 includes a plurality of second linear drive devices 221. Each second linear drive device 221 has a second fixed part and a second movable part that are movable relative to each other along a straight line. One of the second fixed part and the second movable part is connected to the fixed body, and the other is connected to the movable body. In an embodiment of the present invention, the second linear drive device 221 is configured as a hydraulic rod. One end of the hydraulic rod is fixedly disposed at the support part 23 and drives the first connecting seat 24 to move along the first direction. Another hydraulic rod is fixedly disposed at the first connecting seat 24 and drives the second connecting seat 25 to move along the second direction. The other hydraulic rods are fixedly disposed at the second connecting seat 25 and drive the third connecting seat 26 to move along the third direction, thereby realizing a high degree of freedom of movement of the clamping part 21, i.e., the root of the blade.

[0069] Furthermore, a rotating seat 261 is provided at the third connecting seat 26. The rotating seat 261 is rotatably mounted on the third connecting seat 26 along a third-direction extending axis. The clamping part 21 is mounted to the rotating seat 261, that is, the clamping part 21 can be driven by the rotating seat 261 to rotate, thereby achieving high-degree-of-freedom movement control from three directions with corresponding rotation angles. This can effectively improve the alignment accuracy during blade installation, thereby increasing construction efficiency. In addition, the driving part 22 includes a third rotary driving device 222. 22 has a third fixed part and a third movable part that are rotatable along a third-direction axis. One of the third fixed part and the third movable part is connected to the third connecting seat 26, and the other is connected to the rotating seat 261. It should be noted that, in the embodiment of the present invention, the rotating seat 261 is also provided with a bracket, and the bracket is provided with a bearing and a rotating shaft. The clamping part 21 is connected to the bracket through the rotating shaft to maintain a certain degree of freedom of the clamping part 21 and avoid damage to the blade when moving the blade due to the clamping part 21 being fixed and locked.

[0070] Please refer to Figure 6 The support part 23 includes: a support body 231, multiple connecting rods 232, and a lifting rod 233. It can be understood that the support body 231 is used to fix the multiple connecting rods 232. In this application, the support body 231 and the multiple connecting rods 232 are welded together to improve their connection strength. The multiple connecting rods 232 and the fixing part 1 are also connected by welding. In addition, the lifting rod 233 is bent and fixedly connected to the support body 231. In actual application, the bent part of the lifting rod 233 is used to connect with the hoisting structure to facilitate the connection of the hoisting structure and disassembly of the wind turbine blade installation equipment 1000.

[0071] The present invention also proposes a method for aligning and installing wind turbine blades, including the aforementioned wind turbine blade installation equipment 1000, the method comprising the following steps:

[0072] When the tower and the fixing part 1 have been installed in the preset position, the driving part 22 is controlled to drive the clamping part 21 to the open state.

[0073] When the blade approaches the clamping part 21, the driving part 22 is controlled to drive the clamping part 21 to a closed state to clamp the blade;

[0074] The drive unit 22 is controlled to move from its original position to a set position, so as to drive the root of the blade to move to the alignment position that mates with the hub;

[0075] After the blade is aligned and installed onto the hub, the drive unit 22 is controlled to drive the clamping unit 21 to the open state;

[0076] The drive unit 22 is controlled to return to its original position to provide clearance.

[0077] Control the hub to rotate, thereby causing the blades to rotate away from the alignment position, and repeat the above steps until all the blades are installed.

[0078] Specifically, in an embodiment of the present invention, the wind turbine blade alignment and installation method further includes the following steps:

[0079] When the tower and the fixing part 1 have been installed in the preset position, the first linear drive device 214 is controlled to drive each of the clamping teeth 212 to move in a direction away from each other.

[0080] When the blade is installed at the support body 211, the first linear drive device 214 is controlled to drive each of the clamping teeth 212 to move in a direction that approaches each other in order to clamp the blade.

[0081] The second linear drive device 221 and the third rotary drive device 222 are controlled to move from their original positions to a set position, so as to drive the root of the blade to move to the alignment position that mates with the hub;

[0082] After the blade is aligned and installed on the hub, the first linear drive device 214 is controlled to drive each of the clamping teeth 212 to move in a direction away from each other.

[0083] The second linear drive device 221 and the third rotary drive device 222 are controlled to return to their original positions to provide clearance space;

[0084] Control the hub to rotate, thereby causing the blades to rotate away from the alignment position, and repeat the above steps until all the blades are installed.

[0085] Specifically, in this application, the phrase "when the tower and the fixing part 1 have been installed in a preset position" specifically refers to closing the clamping structure 11 and fixing it to the tower along a third direction. At this time, the first linear drive device 214 is controlled to drive each of the clamping teeth 212 to move in a direction away from each other, so as to open the clamping teeth 212 and facilitate the installation of the blade root. Then, the blade is hoisted to the supporting body 211 by the hoisting equipment. At this time, the first linear drive device 214 is controlled to drive each of the clamping teeth 212 to move in a direction closer to each other, so as to clamp the root of the blade and fix the root of the blade. Then, the second linear drive device 221 is first controlled to drive the clamping part 21 to move the blade in three directions closer to the alignment position of the hub. Then, the third rotary drive device 221 is driven to move the clamping part 21 to move the blade closer to the alignment position of the hub. 22. Adjust the angle of the blade root to fit the hub and install the blade. Then, after the blade is aligned and installed on the hub, control the first linear drive device 214 to drive each clamping tooth 212 to move in a direction away from each other, so that the blade can disengage from the clamping part 21. Subsequently, control the second linear drive device 221 and the third rotary drive device 222 to return to their original positions to provide clearance space for the blade to rotate in a third direction. Specifically, the rotation angle is 120°, and rotate the part of the hub without blades to a suitable position to facilitate the subsequent installation of the blades. Repeat the above steps until all blades are installed. Then, remove the pin 121 using the hoisting equipment and connect the support part 23, and disassemble the wind turbine blade installation device 1000.

[0086] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
