[0047] As used herein, "a plurality" means two or more (including two).

[0048] Referring to Figures 1 to 10 As shown, the embodiments of the present application provide a manufacturing method of a wind turbine blade, which comprises: providing a wind turbine blade mold 10, comprising a windward surface mold 1 and a leeward surface mold 2; The windward surface mold 1 is in an open state relative to the leeward surface mold 2, a first shell 11 with a windward surface is arranged on the windward surface mold 1, and a second shell 21 with a leeward surface is arranged on the leeward surface mold 2; providing a web flanging tool 3, comprising a flanging body 31 and a plate surface positioning piece 32, which are slidably connected along the width direction of the flanging body 31; The web flanging tool 3 is arranged on the inner wall of the first shell 11 and the inner wall of the second shell 21 respectively along the length direction Z of the wind turbine blade, and the length direction of the flanging body 31 is the same as the length direction Z of the wind turbine blade; Measuring a first inclination angle K1 of the flanging body 31 located in the first shell 11, and a second inclination angle K2 of the flanging body 31 located in the inner wall of the second shell 21, the first inclination angle K1 and the second inclination angle K2 are acute angles formed between the flanging body 31 and the direction of gravity Y; The windward surface mold 1 is turned over and closed with the leeward surface mold 2 along the direction of gravity Y, and the plate surface positioning piece 32 located in the first shell 11 is arranged corresponding to the plate surface positioning piece 32 located in the second shell 21 along the direction of gravity Y; Measuring the vertical distance between the plate surface positioning piece 32 of the first shell 11 and the plate surface positioning piece 32 of the second shell 21 along the direction of gravity Y; Manufacturing a web mold 4 according to the width S1 of the flanging body, the first inclination angle K1, the second inclination angle K2 and the vertical distance; Manufacturing a web 7 using the web mold 4, the flange 72 of the web 7 matches the width S1 of the flanging body, the first inclination angle K1 and the second inclination angle K2, and the height of the plate surface 71 of the web 7 matches the vertical distance.

[0049] In some realizable ways, the inner wall of the first shell 11 and the inner wall of the second shell 21 are both provided with a web bonding area (not shown in the figure).

[0050] The windward mold 1 is controlled to be in a fully open state relative to the leeward mold 2, the first shell 11 is formed and cured in the windward mold 1, and the second shell 21 is formed and cured in the leeward mold 2. After the first shell 11 and the second shell 21 are cured, all auxiliary materials and irrelevant articles on the inner skin of the first shell 11 and the second shell 21 are removed, and the adhesive area of the web plate is completely exposed and clean.

[0051] The adhesive area of the web plate in the inner wall of the first shell 11 and the second shell 21 is positioned and marked along the length direction Z of the wind power blade. The profile-adhesive placement of all web plate flanging tools 3 is sequentially completed from the root to the tip along the length direction Z of the wind power blade, ensuring that the length direction of the flanging body 31 is the same as the length direction Z of the wind power blade. After the adhesive placement, the web plate flanging tool 3 is continuously numbered (1, 2, 3…n) and the position of the plate positioning piece 32 is adjusted, so that the relative position of the flanging body 31 meets the relative relationship between the plate surface 71 of the web plate 7 and the flanging 72 of the web plate 7.

[0052] The coordinate system is unified, the chord direction X of the wind power blade is the X axis, the gravity direction Y is the Y axis, and the length direction Z of the wind power blade is the Z axis. The first inclination angle K1 of each flanging body 31 in the first shell 11 and the second inclination angle K2 of each flanging body 31 in the second shell 21 are measured by using an angle measuring tool.

[0053] After the windward mold 1 is turned over, the windward mold 1 and the leeward mold 2 are closed along the gravity direction Y, and the plate positioning piece 32 of the first shell 11 and the plate positioning piece 32 of the second shell 21 are correspondingly arranged along the gravity direction Y. The vertical distance between the plate positioning piece 32 of the first shell 11 and the plate positioning piece 32 of the second shell 21 along the gravity direction Y is measured and calculated. The web plate mold 4 is manufactured according to the width S1 of the flanging body, the first inclination angle K1 and the second inclination angle K2 measured and the vertical distance calculated. The web plate 7 is manufactured by using the web plate mold 4, ensuring that the flanging 72 of the web plate 7 matches the width S1 of the flanging body, the first inclination angle K1 and the second inclination angle K2, and the height of the plate surface 71 of the web plate 7 matches the vertical distance. The web plate 7 manufactured by the web plate mold 4 is used to be fixed and adhered to the first shell 11 and the second shell 21.

[0054] In some examples, the angle measuring tool can be, but is not limited to, an inclinometer.

[0055] The wind turbine blade manufacturing method of this application embodiment, by setting up a web flange tooling 3, the web flange tooling 3 includes a flange body 31 and a plate surface positioning component 32. The flange body 31 and the plate surface positioning component 32 are slidably connected along the width direction of the flange body 31. By combining the measurement of the first tilt angle K1 and the second tilt angle K2 and the detection of the vertical distance after mold closing, the relevant parameters of the flange 72 of the web 7 and the height matching data of the plate surface 71 can be accurately obtained. There is no need to make complex processes such as web manufacturing and pressing samples. It can directly assist the manufacturing of the web mold 4. Then, the web 7 actually used is manufactured through the web mold 4, realizing the precise adaptation of the web 7 with the first shell 11 and the second shell 21. This reduces the resource waste caused by repeated mold debugging, improves the manufacturing efficiency and forming accuracy of wind turbine blades, and ensures the stability of the mechanical properties of wind turbine blades.

[0056] In some feasible ways, such as Figure 8 As shown, the plate positioning component 32 includes a connected positioning component (not shown in the figure) and a base (not shown in the figure). An adjustment track 311 is provided on the side wall of the flange body 31, extending along the width direction of the flange body 31. The base is slidably connected to the adjustment track 311. By adjusting the relative position S4 between the plate positioning component and the flange body, the relative position of the plate surface 71 and the flange 72 of the actual web 7 can be simulated. For example, when the plate positioning component 32 is located at the edge of the flange body 31, it can simulate that the actual web 7 is an L-shaped web. When the plate positioning component 32 is located in the middle area of ​​the flange body 31, it can simulate that the actual web 7 is an "I"-shaped web.

[0057] In some examples, the positioning element can be, but is not limited to, a laser tracker target ball.

[0058] In some feasible ways, the flange body 31 may be made of, but is not limited to, a non-elastic lightweight material. In some examples, the flange body 31 may be made of, but is not limited to, high-density polyethylene.

[0059] In some feasible ways, such as Figure 9 and Figure 10 As shown, the web mold 4 includes a horizontal plate template 41 and a flange template 42. The flange template 42 is provided on both sides of the horizontal plate template 41. The flange template 42 matches the width S1, the first inclination angle K1, and the second inclination angle K2 of the flange body. The horizontal plate template 41 is used to manufacture the plate surface that matches the vertical spacing, and the flange template 42 is used to manufacture the flange.

[0060] The web plate mold 4 consists of a horizontal plate template 41 and a flange template 42. The flange template 42 is precisely matched with the width S1, the first tilt angle K1, and the second tilt angle K2 of the flange body. The horizontal plate template 41 is adapted to the vertical spacing, and the flange template 42 is adapted to the flange structure. This enables the precise modular manufacturing of the flange 72 structure and the height of the plate 71 of the web plate 7, further improving the dimensional accuracy of the web plate 7. It also ensures that the adhesive layer 8 is of uniform thickness and the adhesive area is precise when the web plate 7 is bonded to the first shell 11 and the second shell 21, thereby enhancing the overall structural stability of the blade.

[0061] In some examples, the thickness of the flange template 42 may be, but is not limited to, 300 mm.

[0062] In some feasible ways, the web mold 4 can be an "I" type web template or an L type web template, wherein the horizontal plate template 41 has flange templates 42 on both sides.

[0063] In some examples, such as Figure 9 As shown, when the web plate mold 4 is an L-shaped web plate template, the fiberglass cloth is directly laid on the horizontal plate template 41 and the flange template 42 of the web plate mold 4. After the laying is completed, the laid fiberglass cloth is injected with resin. After the resin is cured and formed, the formed web plate 7 is demolded from the web plate mold 4 to complete the preparation of the L-shaped web plate.

[0064] In some examples, such as Figure 10 As shown, the web plate mold 4 is a "I" type web plate template. The web plate mold 4 also includes a first auxiliary component 61 and a second auxiliary component 62. The first auxiliary component 61 is fixedly connected to the horizontal plate template 41, and the second auxiliary component 62 is detachably spliced ​​to the horizontal plate template 41. A laying gap 621 is provided between the second auxiliary component 62 and the flange template 42. Fiberglass cloth is laid, with a portion of the laid fiberglass cloth located within the laying gap 621 between the second auxiliary component 62 and the flange template 42. A portion of the fiberglass cloth covers the first auxiliary component 61, the second auxiliary component 62, and the portion of the flange template 42 that extends beyond the second auxiliary component 62. After laying, resin is injected into the laid fiberglass cloth. After the resin has cured and formed, the formed web plate 7 is demolded from the web plate mold 4, completing the preparation of the "I" type web plate.

[0065] For example, the second auxiliary component 62 can be connected to the horizontal panel template 41 and the flange template 42 by means of splicing.

[0066] For example, the first auxiliary component 61 may be made of steel plate material, but is not limited to. The second auxiliary component 62 may be made of silicone material, but is not limited to.

[0067] In some feasible ways, such as Figure 5 , Figure 6As shown, multiple web flanges 3 are provided. The multiple web flanges 3 are sequentially arranged on the inner wall of the first housing 11 and the inner wall of the second housing 21 along the length direction Z of the wind turbine blade.

[0068] Multiple web flange fixtures 3 are set along the length direction Z of the wind turbine blade, which can fully cover the matching requirements of the web 7 at different axial positions of the blade, obtain accurate first tilt angle K1, second tilt angle K2 and vertical spacing data of each section, reduce the possibility of local error caused by measurement of a single web flange fixture 3, and at the same time, by setting multiple web flange fixtures 3, the web flange fixtures 3 can be better fitted to the shape of the first shell 11 and the second shell 21.

[0069] In some feasible ways, the length S2 of each flange body can be, but is not limited to, 20 centimeters.

[0070] In some feasible ways, such as Figure 9 and Figure 10 As shown, multiple flange templates 42 are sequentially connected to the surface of one end of the horizontal plate template 41. Each flange template 42 matches the width S1 and the first tilt angle K1 of each flange body set in the first housing 11. Adjacent flange templates 42 are connected and fixed to each other.

[0071] Multiple flange templates 42 are sequentially connected to the other end of the horizontal plate template 41. Each flange template 42 matches the width S1 and the second tilt angle K2 of each flange body set in the second housing 21. Adjacent flange templates 42 are connected and fixed to each other.

[0072] By connecting multiple flange templates 42 sequentially to the horizontal plate template 41 and fixing adjacent flange templates 42, each flange template 42 forms a continuous and flat structure. This not only matches the width S1 and the first tilt angle K1 and the second tilt angle K2 of the flange body 31 at each axial position, but also ensures a smooth transition of the flange templates 42, reducing the possibility of adhesive stress concentration caused by splicing defects of the flange templates 42. At the same time, it simplifies the assembly process of the web plate mold 4 and improves the efficiency of web plate mold 4 manufacturing and web plate 7 production.

[0073] In some feasible methods, when installing and adjusting the web mold 4, a leveling and testing instrument is first used to detect the height difference of the horizontal plate template 41. The web mold 4 is then adjusted according to the height difference detection data. After all the horizontal plate templates 41 are at the same elevation, the horizontal plate templates 41 are fixed. Subsequently, the flange template 42 is prepared, and the flange template 42 is matched with the width S1, the first inclination angle K1, and the second inclination angle K2 of the flange body.

[0074] Next, according to the numbering order of each web flange tooling 3 from the blade root to the blade tip, the multiple flange templates 42 corresponding to each web flange tooling 3 on the windward mold 1 are sequentially connected to the plate surface of one end of the horizontal plate template 41; then the multiple flange templates 42 corresponding to each web flange tooling 3 on the leeward mold 2 are sequentially connected to the plate surface of the other end of the horizontal plate template 41.

[0075] In some feasible ways, the leveling instrument can be, but is not limited to, a level or spirit level.

[0076] In some feasible ways, the flange template 42 and the horizontal panel template 41 may be made of stainless steel, but are not limited to.

[0077] In some feasible ways, the flange template 42 can be connected to the horizontal plate template 41 and the flange template 42 by welding, but not limited to welding.

[0078] In some feasible ways, such as Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, when the windward mold 1 is closed relative to the leeward mold, the chordal direction X of the wind turbine blade is the X-axis, the gravity direction Y is the Y-axis, and the length direction Z of the wind turbine blade is the Z-axis.

[0079] Measure the three-dimensional coordinates of each plate positioning element 32 located on the first housing 11. : where i is 1, 2, 3...n Measure the three-dimensional coordinates of each plate positioning element 32 located on the second housing 21. : where i is 1, 2, 3...n Vertical spacing equal and The difference between them, that is, , where i is 1, 2, 3...n.

[0080] With a defined coordinate system as the reference, the chord direction X of the wind turbine blade is the X-axis, the gravity direction Y is the Y-axis, and the length direction Z of the wind turbine blade is the Z-axis. The vertical spacing is directly calculated by measuring the three-dimensional coordinates of the plate positioning parts 32 of the first shell 11 and the plate positioning parts 32 of the second shell 21. This makes the vertical spacing data more accurate and quantifiable, reduces the possibility of subjective errors caused by manual measurement, improves the dimensional accuracy of the height of the plate surface 71 of the web plate 7, and enables the web plate 7 manufactured using the web plate mold 4 to be highly compatible with the first shell 11 and the second shell 21.

[0081] In some feasible ways, the three-dimensional coordinates of the respective plate positioning elements 32 of the first housing 11 and the second housing 21 can be measured using coordinate measuring tools.

[0082] In some examples, the coordinate measuring tool can be, but is not limited to, a laser tracker.

[0083] In some feasible methods, the windward mold 1 is rotated 180° relative to the leeward mold and is positioned directly above the leeward mold in a mold-closing state. The three-dimensional coordinates of the positioning elements 32 on each plate surface of the first housing 11 are measured. : where i is 1, 2, 3...n Select marker points on the windward mold 1, corresponding to the area positioned on the plate surface, and measure the three-dimensional coordinates of the marker points. : where i is 1, 2, 3...n Then, the windward mold 1 descends along the gravity direction Y and merges with the leeward mold, and the three-dimensional coordinates of the marker point are measured again. : i is 1, 2, 3...n The coordinates of the positioning components on each plate surface of the first shell along the gravitational direction Y are calculated when the windward mold is closed relative to the leeward mold. : .

[0084] By measuring the three-dimensional coordinates of the marker points after the windward mold 1 is flipped and in the mold-closed state, the Y-axis coordinate of the plate positioning part 32 of the first shell 11 is corrected, and the height deviation in the gravity direction Y during the mold flipping and mold-closing process is compensated, ensuring that the height of the plate surface 71 of the web plate 7 is fully matched with the actual assembly requirements, and reducing the possibility of abnormal assembly gaps or adhesive layer 8 thickness caused by mold movement errors.

[0085] In some feasible ways, such as Figure 5 and Figure 6 As shown, with the windward mold 1 in the open state relative to the leeward mold 2, the three-dimensional coordinates of the positioning parts 32 on each plate surface of the first housing 11 are measured. : where i is 1, 2, 3...n The wind turbine blade mold 10 also includes a plurality of tilting arms 5 spaced apart along its length. The tilting arms 5 connect the windward mold 1 and the leeward mold 2. The windward mold 1 tilts relative to the leeward mold 2 along the tilting axis of the tilting arms 5. Measure the three-dimensional coordinates of the projection points of the positioning components 32 on each plate surface of the first housing 11 on the flip axis. :

[0086] , The three-dimensional coordinates of the positioning components 32 on each plate surface of the first housing are calculated to obtain the mold-closing state when the windward mold 1 is rotated 180° relative to the leeward mold 2 and is directly above the windward mold 2. : .

[0087] in, .

[0088] By calculating the projection point of the plate positioning component 32 of the first housing 11 on the flipping axis, the coordinates after flipping 180° are derived, and the actual position of the windward mold 1 after flipping is accurately simulated. This reduces the possibility of errors in the coordinate measurement of the plate positioning component 32 caused by the deviation of the flipping angle, and ensures the dimensional accuracy of the web mold 4 manufacturing and the web 7 production.

[0093] i is 1, 2, 3...n.

[0094] ,

[0095] i is 1, 2, 3...n.

[0096] The determination method of the flipping axis and the calculation method of the projection parameters are clarified. By measuring the three-dimensional coordinates of the midpoint of the flipping axis of the first flipping arm 5 and the last flipping arm 5, the straight line equation of the flipping axis is determined, and the projection parameters and projection point coordinates are obtained. This makes the calculation data of the projection point coordinates of the plate positioning part 32 of the first shell 11 more accurate, effectively reducing the possibility of coordinate derivation error caused by inaccurate positioning of the flipping axis, and ensuring the accuracy of the manufacturing of the quasi-web mold 4 and the production of the web 7 after the position of the plate positioning part 32 is simulated after flipping.

[0097] In some feasible ways, such as Figure 5 As shown, the wind turbine blade mold 10 includes 11 tilting arms 5, which connect the windward mold 1 and the leeward mold 2. Figure 5 The leftmost flip arm 5 is the first flip arm 5, and the 11th flip arm 5 is the last flip arm 5.

[0098] In some feasible ways, such as Figure 7 As shown, the flange 72 of the web plate 7 is bonded to the first shell 11 and the second shell 21 through the adhesive layer 8, and the thickness S3 of the flange body is equal to the thickness of the adhesive layer 8.

[0099] The thickness S3 of the flange body 31 is kept consistent with the thickness of the adhesive layer 8. While the flange body 31 simulates the flange structure of the actual web, the actual thickness requirement of the adhesive layer 8 is accurately reproduced. This reduces the possibility that the bonding strength between the flange 72 of the actual web 7 and the first shell 11 or the second shell 21 will be affected by the design deviation of the thickness of the adhesive layer 8. This ensures that the mechanical properties of the actual web 7 after bonding with the first shell 11 and the second shell 21 meet the design standards and improves the structural reliability of the blade during operation.

[0100] In some feasible ways, such as Figure 7 As shown, the thickness S3 of the flange body ranges from 2 mm to 8 mm.

[0101] The thickness S3 of the flange body is limited to a range of 2 mm to 8 mm to match the optimal thickness requirement of the adhesive layer 8 of the wind turbine blade. This ensures that the bonding strength meets the mechanical performance requirements of the blade while reducing the possibility of bonding defects caused by the adhesive layer 8 being too thick or too thin, thus balancing bonding quality and production feasibility.

[0102] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
