Description

Technical Field

[0001] This invention belongs to the field of non-metallic composite material wind turbine blade hoisting technology, specifically relating to a wind turbine blade hoisting anti-clamping deformation tool and its usage method. Background Technology

[0002] In recent years, grid parity for large-megawatt wind turbines has become a development trend in the wind power industry. Wind turbine blade suppliers are focusing on lightweight blade design through blade structure optimization and the selection of new materials. Currently, during the installation of large-megawatt wind turbine blades in wind farms, special lifting fixtures are often used to clamp the blades at the two sides of the blade's center of gravity. The clamping force of the lifting fixtures acts directly on the main beam area of ​​the blade's lifting points. The PS and SS main beams of the wind turbine blade are connected by a web. When the clamps of the lifting fixtures hold the main beams of the wind turbine blade, they often cause deformation of the blade's web, resulting in structural damage. Therefore, during the blade structure design process, it is necessary to structurally reinforce the web of the wind turbine blade in the lifting point area to resist the clamping force of the lifting fixtures. The structural reinforcement of the web in the lifting point area of ​​large-megawatt blades can reach 100kg to 200kg, leading to an increase in blade weight and material costs, which is not conducive to reducing the cost of wind turbine blades. Summary of the Invention

[0003] To address the aforementioned technical problems of blade deformation caused by clamping of wind turbine blades by blade hoisting fixtures and excessive weight increase caused by reinforcement of the web structure in the hoisting point area of ​​large-megawatt wind turbine blades, this invention provides a wind turbine blade hoisting anti-clamping deformation fixture and its usage method.

[0004] The objective of this invention is achieved through the following technical solution. A wind turbine blade hoisting anti-clamping deformation fixture according to this invention includes a PS surface component, an SS surface component, and a main component for matching with the web of the wind turbine blade. The PS surface component and the SS surface component are respectively hinged to both sides of the main component. The side of the PS surface component away from the main component matches the inner wall of the PS surface main beam in the wind turbine blade, and the side of the SS surface component away from the main component matches the inner wall of the SS surface main beam in the wind turbine blade.

[0005] Furthermore, the PS surface component, SS surface component, and main component are all flat plate structures made of composite materials or metal materials.

[0006] Furthermore, the bottom of the PS surface component that matches the main component is provided with a PS serrated portion, which includes multiple serrations spaced apart along the length direction. A PS through hole is provided on the PS serrated portion, penetrating each serration and extending along the length direction. The side of the main component near the PS surface component is an upper serrated portion, which includes multiple serrations spaced apart along the length direction. An upper through hole is provided on the upper serrated portion, penetrating each serration and extending along the length direction. The PS serrated portion on the PS surface component and the upper serrated portion on the main component mesh with each other, and the PS through hole and the upper through hole are aligned and connected, and a fixing rod is inserted at the same time. A gap is left between the fixing rod and the PS through hole and the upper through hole.

[0007] Furthermore, the top of the SS surface component that matches the main component is provided with an SS serrated portion. The SS serrated portion includes multiple serrations spaced apart along the length direction. The SS serrated portion is provided with an SS through hole that penetrates each serration and extends along the length direction. The side of the main component near the SS surface component is a lower serrated portion. The lower serrated portion includes multiple serrations spaced apart along the length direction. The lower serrated portion is provided with a lower through hole that penetrates each serration and extends along the length direction. The SS serrated portion of the SS surface component and the lower serrated portion on the main component mesh with each other. The SS through hole and the lower through hole are aligned and connected, and a fixing rod is inserted through them. A gap is left between the fixing rod and the SS through hole and the lower through hole.

[0008] Furthermore, the fixing rod is a cylindrical metal rod, and the through hole where the fixing rod is located is 0.2 to 0.6 mm larger than the diameter of the fixing rod.

[0009] Furthermore, a magnetic fixing block is provided on the outer surface of the main component.

[0010] A method for using a wind turbine blade hoisting anti-clamping deformation fixture includes the following steps:

[0011] The various components of the wind turbine blade hoisting anti-clamping deformation tooling are transported into the wind turbine blade.

[0012] Assemble and attach the anti-clamping deformation tooling for wind turbine blade hoisting to the sides of each web plate in the corresponding hoisting point area;

[0013] After the blades are hoisted, the anti-clamping deformation jigs for the wind turbine blades are removed, and then the hoisted wind turbine blades are transported out.

[0014] Furthermore, when installing the anti-clamping deformation tooling for wind turbine blade hoisting, first place the SS surface component on the SS surface shell of the wind turbine blade, then install the main component and PS surface component in sequence, so that each component fits against the web surface, and the PS surface component abuts against the inner wall of the shell in the corresponding area of ​​the PS surface main beam, and the SS surface component abuts against the inner wall of the shell in the corresponding area of ​​the SS surface main beam. Finally, hinge each component together.

[0015] Furthermore, when fixing the wind turbine blade hoisting anti-clamping deformation fixture onto the web plate, fixing blocks are attached to the outer surface of the wind turbine blade hoisting anti-clamping deformation fixture, and the fixing blocks of the wind turbine blade hoisting anti-clamping deformation fixture on both sides of the same web plate are symmetrically arranged.

[0016] Furthermore, when removing each anti-deformation fixture, first remove the fixing block from the anti-deformation fixture, then release the hinge relationship between the PS surface component, the main component, and the SS surface component, and finally remove the PS surface component, the main component, and the SS surface component in sequence.

[0017] Compared with the prior art, the advantages of the present invention are: the anti-deformation tooling has a simple structure, low cost, and strong versatility, and can be used for different types of wind turbine blades to resist web deformation; the anti-deformation tooling helps to eliminate the need for web structure reinforcement at blade suspension points, reduce the amount of wind turbine blade material, save costs and reduce blade weight, while preventing web deformation.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] An example embodiment of the wind turbine blade hoisting anti-clamping deformation tool of the present invention Figures 3 to 4 As shown, hereinafter referred to as anti-deformation fixture 3.

[0035] Anti-deformation tooling 3 is used for, for example Figures 1a to 1b The wind turbine blade 1 shown has a blade center of gravity marker 13 on its outer surface to mark the position of the center of gravity of the wind turbine blade 1, and anti-deformation fixture 3 is installed on both sides of the center of gravity of the wind turbine blade 1.

[0036] The wind turbine blade 1 comprises a shell, a main beam, and a web. The shell includes a PS-surface shell 101 and an SS-surface shell 102. The main beam includes a PS-surface main beam 111 and an SS-surface main beam 112, both mounted on the shell. The PS-surface main beam 111 is located on the PS-surface shell 101, and the SS-surface main beam 112 is located on the SS-surface shell 102. The web 12 includes a trailing edge web 121 and a leading edge web 122. The web 12 is located between the PS-surface shell 101 and the SS-surface shell 102 and is bonded to the main beam.

[0037] The basic structure of hoisting fixture 2 is as follows: Figure 2a As shown, it is used to clamp and lift the wind turbine blade 1, such as Figures 2b to 2c As shown. The hoisting fixture 2 includes a main fixture frame 21, a center-of-gravity root clamp 22 and a center-of-gravity tip clamp 23 mounted on the main fixture frame 21.

[0038] When clamping the wind turbine blade 1, the center of gravity root clamp 22 is located in the center of gravity root side lifting point area 14 on the side of the wind turbine blade's center of gravity close to the root. The center of gravity root clamp 22 is provided with PS surface clamping plate 221 and SS surface clamping plate 222, which are respectively clamped on the outside of the PS surface main beam 111 and SS surface main beam 112 of the center of gravity root side lifting point area 14 of the wind turbine blade 1.

[0039] When clamping the wind turbine blade 1, the center-of-gravity tip clamp 23 is located in the center-of-gravity tip side lifting point area 15 on the side of the wind turbine blade's center of gravity close to the tip. The center-of-gravity tip clamp 23 is provided with a PS surface clamping plate 231 and an SS surface clamping plate 232, which are respectively clamped on the outside of the PS surface main beam 111 and the SS surface main beam 112 of the center-of-gravity tip side lifting point area 15 of the wind turbine blade 1.

[0040] The structure and assembly process of the anti-deformation tooling 3 are as follows: Figure 3 As shown, the anti-deformation fixture 3 is fitted onto the web surface of the lifting point area (including the lifting point area 14 at the root of the center of gravity and the lifting point area 15 at the tip of the center of gravity) during use. The anti-deformation fixture 3 includes a PS surface component 31, an SS surface component 32, and a main component 33. All three components are flat plate structures made of composite materials or metal. The PS surface component 31 and the SS surface component 32 are hinged to both sides of the main component 33. After adjusting the relative positions of the PS surface component 31, the SS surface component 32, and the main component 33, the two sides of the anti-deformation fixture 3 can be made flat, facilitating its fit onto the web inside the wind turbine blade 1.

[0041] In this embodiment, the PS surface component 31 and the SS surface component 32 have mutually matching structures with the main component 33, and the mutually matching structures are provided with mutually aligned through holes. Fixing rods 34 are inserted through the mutually aligned through holes on the matching structures of the PS surface component 31, the SS surface component 32 and the main component 33. A gap is left between the outer wall of the fixing rod 34 and the inner wall of the above-mentioned through hole, so that the PS surface component 31, the SS surface component 32 and the main component 33 can rotate relative to each other.

[0042] The top shape of the PS surface component 31, away from the main component 33, matches the inner wall of the shell in the area where the PS main beam of the corresponding lifting point region is located, and its length is equal to the length of the corresponding lifting point region. In this embodiment, the bottom of the PS surface component 31 that matches the main component 33 is provided with a PS serrated portion 311. The PS serrated portion 311 includes a plurality of serrations spaced apart along the length direction, and the PS serrated portion 311 is provided with a PS through hole 313 that penetrates each serration and extends along the length direction.

[0043] The bottom shape of the SS surface component 32, away from the main component 33, matches the inner wall of the shell in the area where the SS main beam of the corresponding lifting point region is located, and its length is equal to the length of the corresponding lifting point region. In this embodiment, the top of the SS surface component 32 that matches the main component 33 is provided with an SS serrated portion 321. The SS serrated portion 321 includes a plurality of serrations spaced apart along the length direction, and the SS serrated portion 321 is provided with an SS through hole 324 that penetrates each serration and extends along the length direction.

[0044] In this embodiment, the side of the main component 33 near the PS surface component 31 is an upper serrated portion 331, which includes a plurality of serrations spaced apart along the length direction. An upper through hole 333 is provided on the upper serrated portion 331, penetrating each serration and extending along the length direction. The side of the main component 33 near the SS surface component 32 is a lower serrated portion 332, which includes a plurality of serrations spaced apart along the length direction. A lower through hole 334 is provided on the lower serrated portion 332, penetrating each serration and extending along the length direction. The PS serrated portion 311 on the PS surface component 31 meshes with the upper serrated portion 331 on the main component 33, and the PS through hole 313 is aligned and connected to the upper through hole 333. The SS serrated portion 321 on the SS surface component 32 meshes with the lower serrated portion 332 on the main component 33, and the SS through hole is aligned and connected to the lower through hole 334. The fixing rod 34 is a cylindrical metal rod. The PS through hole 313, upper through hole 333, SS through hole 324, and lower through hole 334 have the same diameter and are 0.2 to 0.6 mm larger than the diameter of the fixing rod 34. The two fixing rods 34 are respectively inserted into the PS through hole 313, upper through hole 333, SS through hole 324, and lower through hole 334, so that the PS surface component 31 and SS surface component 32 can rotate relative to the main component 33.

[0045] like Figure 4 As shown, before hoisting a wind turbine blade, eight sets of anti-deformation fixtures 3 need to be installed inside the wind turbine blade 1. Four sets of anti-deformation fixtures 3 are used in the root-side hoisting area 14 and the tip-side hoisting area 15 of the wind turbine blade 1. Each hoisting area includes a leading edge web 122 and a trailing edge web 121. One set of anti-deformation fixtures 3 is used on each side of the leading edge web 122 and each side of the trailing edge web 121.

[0046] The eight sets of anti-deformation fixtures 3 have the same structural form, and the anti-deformation fixtures 3 are fitted to the side of the web plate corresponding to the lifting point area. In this embodiment, the main components 33 of each set of anti-deformation fixtures 3 have the same structural dimensions, which facilitates mass production. The top shape of the PS surface component 31 away from the main component 33 is the same as and matches the airfoil of the inner wall of the shell in the area corresponding to the PS surface main beam. The bottom shape of the SS surface component 32 away from the main component 33 is the same as and matches the airfoil of the inner wall of the shell in the area corresponding to the SS surface main beam.

[0047] In each lifting point region, the total height of the anti-deformation fixture 3 used on the leading edge side of the leading edge web 122 is equal to the leading edge side height of the leading edge web 122; the total height of the anti-deformation fixture 3 used on the trailing edge side of the leading edge web 122 is equal to the trailing edge side height of the leading edge web 122. The total height of the anti-deformation fixture 3 used on the trailing edge side of the trailing edge web 121 is equal to the trailing edge side height of the trailing edge web 121; the total height of the anti-deformation fixture 3 used on the leading edge side of the trailing edge web 121 is equal to the leading edge side height of the trailing edge web 121.

[0048] Eight sets of anti-deformation lifting fixtures 3 are installed close to the surface of the corresponding web plates. During clamping and lifting, the eight sets of anti-deformation lifting fixtures 3 are respectively located between the PS surface clamping plate 221 and the SS surface clamping plate 222 at the root of the center of gravity, and between the PS surface clamping plate 231 and the SS surface clamping plate 232 at the tip of the center of gravity. When each PS surface clamping plate and SS surface clamping plate applies clamping force to the main beam and web plate, the anti-deformation fixtures 3 can share part of the clamping force and prevent the web plate from deforming. After the wind turbine blade is clamped and lifted, the anti-deformation fixtures are removed to reduce the weight of the wind turbine blade, and the anti-deformation fixtures can be reused.

[0049] After the anti-deformation fixture 3 is installed on the web, fixing blocks 4 are provided on the outer surfaces of the anti-deformation fixture 3 on both sides of the same web to ensure that the anti-deformation fixture 3 is fixed to the web. The fixing blocks 4 are made of magnetic material and are symmetrically arranged on both sides of the web. The two symmetrical fixing blocks 4 generate an attractive force to fix the anti-deformation fixture 3 to the web. In this embodiment, six fixing blocks 4 are provided on each anti-deformation fixture.

[0050] The fixing block 4 can also be pre-set on the main component 33. After the two main components 33 are attached to the same web, the main component 33 is fixed to the web by the suction of the fixing block 4, and then the PS surface component and SS surface component are fixed to the web.

[0051] Because the web height is relatively large at the locations of the center of gravity root side lifting point area 14 and the center of gravity tip side lifting point area 15, if the anti-deformation fixture 3 is a single piece, it may get stuck when being transported into the wind turbine blade, making transportation difficult. The anti-deformation fixture 3 of the present invention is set in three parts, which makes it easier to transport the components of the anti-deformation fixture 3 into the wind turbine blade, and then complete the assembly after transportation.

[0052] The PS surface component 31 and SS surface component 32, which are hinged on both sides of the anti-deformation fixture 3, have a certain tolerance. If the height of the web plate of the side lifting point area 14 at the root of the center of gravity and the side lifting point area 15 at the tip of the center of gravity is slightly lower than the height of the corresponding anti-deformation fixture 3, it is easy to get stuck when installing the anti-deformation fixture. The PS surface component 31 and SS surface component 32 can be deflected outward to reduce the overall height of the anti-deformation fixture and make the anti-deformation fixture install in place. At the same time, because there is a gap between the fixing rod and the corresponding through hole, it can float in the height direction to match the height of the web plate.

[0053] The detachable anti-deformation fixture 3 of this invention can reduce the reinforcement of the web plate in the lifting point area of ​​the wind turbine blade 1, thereby reducing the material usage of the wind turbine blade. The anti-clamping deformation fixture of this invention can be used to lift the wind turbine blade by clamping the main beam of the wind turbine blade without web reinforcement at the lifting point, while preventing web deformation. The anti-deformation fixture of this invention has a simple structure, low cost, and can be reused for the same type of wind turbine blade.

[0054] An embodiment of the method for using a wind turbine blade hoisting anti-clamping deformation fixture of the present invention, as follows: Figures 5 to 6 As shown, it includes the following steps:

[0055] 1. Transport all components of the eight sets of anti-deformation fixtures 3 to the corresponding web areas inside the wind turbine blades.

[0056] 2. Assemble the anti-deformation fixture 3 on the front edge of the rear edge web plate 121 of the lifting point area 14 at the root of the center of gravity: First, place the SS surface component 32 on the SS surface shell 102, and install the main component 33 and the PS surface component 31 in sequence, so that each component is attached to the surface of the web plate, and the PS surface component abuts against the inner wall of the shell in the corresponding area of ​​the PS surface main beam, and the SS surface component abuts against the inner wall of the shell in the corresponding area of ​​the SS surface main beam. Then, insert the fixing rod 34 into each through hole respectively.

[0057] 3. Repeat step 2 to complete the installation of the anti-deformation fixtures 3 on the rear edge side of the rear edge web plate 121 of the center of gravity root side lifting point area 14, both sides of the front edge web plate 122 of the center of gravity root side lifting point area 14, both sides of the rear edge web plate 121 of the center of gravity tip side lifting point area 15, and both sides of the front edge web plate 122 of the center of gravity tip side lifting point area 15.

[0058] 4. Six fixing blocks 4 are attached to the outer surface of each anti-deformation fixture 3. The fixing blocks 4 on the anti-deformation fixture 3 on both sides of the same web are symmetrically arranged to ensure that the anti-deformation fixture 3 will not fall off when the wind turbine blade 1 is clamped by the hoisting fixture 2.

[0059] 5. After the blade is hoisted, remove each anti-deformation fixture 3. When removing each anti-deformation fixture 3, first remove the fixing block 4 from the anti-deformation fixture 3, then take out the fixing rod 34, and remove the PS surface component 31, main component 33, and SS surface component 32 in sequence.

[0060] 6. After removing the eight sets of anti-deformation fixtures 3, transport out the wind turbine blades that have been hoisted, and then continue to use them for hoisting other wind turbine blades of the same model.

[0061] When using the anti-deformation fixture 3, the installation sequence can be adjusted according to the actual working conditions. For example, after installing the anti-deformation fixtures on both sides of the same web, immediately install fixing blocks 4 on the outer surface of the anti-deformation fixture 3 to fix it to the corresponding web. Then install the anti-deformation fixtures 3 on other webs to prevent them from falling off during installation, thus affecting installation efficiency. Alternatively, when removing the anti-deformation fixture, first remove all fixing blocks 4 from each web, then remove the anti-deformation fixture 3 to improve removal efficiency.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
