[0019] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0021] As people become increasingly aware of environmental protection, clean energy is receiving more and more attention. Wind energy, as a clean energy source, has garnered particular interest. To fully utilize wind energy, wind turbine generators are being used more and more widely.

[0022] As components that directly interact with wind power, wind turbine blades are crucial for wind turbine generators. With the increasing size of wind turbine generators, the dimensions of wind turbine blades are also constantly increasing, as are the number of components such as the web. Since the placement of these components affects the structural strength of the wind turbine blade, accurately positioning them at predetermined locations within the blade is of paramount importance for improving its quality and is attracting increasing attention from those skilled in the art.

[0023] Currently, in the production process of wind turbine blades, workers typically use traditional spirit levels and plumb lines to determine the placement of components such as the web within the blade mold, ensuring accurate positioning of these components. This method requires constant monitoring of levelness, suffers from poor stability, and is prone to errors in determining the placement of components like the web within the mold. This results in insufficient positioning accuracy for the web and other components, negatively impacting the overall quality of the wind turbine blades.

[0024] Some embodiments of this application provide a positioning device for wind turbine blade production. This device includes a crossbar, a leveling device, an indicating component, and two leveling adjustment components connected to the crossbar. The crossbar extends along a first direction and has a starting mark. The crossbar is positioned on the blade mold and spans the opening of the mold's inner cavity. The leveling device is connected to the crossbar and measures the tilt angle between the crossbar and the horizontal plane. The two leveling adjustment components are spaced apart relative to each other along the first direction and are respectively connected to both sides of the blade mold in the first direction. The starting mark is located between the two leveling adjustment components and is aligned with the edge of the blade mold's inner cavity in the first direction. The two leveling adjustment components are connected to the crossbar and adjust the tilt angle between the crossbar and the horizontal plane. The indicating component is located between the two leveling adjustment components and includes a laser pointer and a first distance measuring device. The laser pointer is movably connected to the crossbar along the first direction, and the laser pointer's emitting end is perpendicular to the first direction. The laser pointer is used to indicate a positioning mark on the blade mold, and the first distance measuring device measures the distance of the laser pointer from the starting mark along the first direction. With the above structure, the positioning device for the wind turbine blade production process can adjust the tilt angle between the crossbar and the horizontal plane through two horizontal adjustment components, so that the crossbar is parallel to the horizontal plane. The operator can use the positioning mark shown by the laser pointer in the indicator component to position the blade mold at a preset distance from the starting mark along the first direction. This makes it convenient for the operator to set or form the components in the wind turbine blade at this location, so that the components in the wind turbine blade can be accurately positioned in the wind turbine blade, which improves the positioning accuracy of each component in the wind turbine blade and helps to improve the quality of the wind turbine blade.

[0025] The positioning device and positioning method for the wind turbine blade production process provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This application provides a positioning device for the wind turbine blade manufacturing process, referenced... Figures 1-4The positioning device for the wind turbine blade production process includes a crossbar 1, a leveling device 2, an indicating component 4, and two leveling adjustment components 3 connected to the crossbar 1. The crossbar 1 extends along a first direction X and is provided with a starting mark 11. The crossbar 1 is used to be placed on the blade mold 100 and spans the opening of the inner cavity of the blade mold 100. The leveling device 2 is connected to the crossbar 1 and is used to measure the tilt angle of the crossbar 1 with respect to the horizontal plane. The two leveling adjustment components 3 are arranged at intervals along the first direction X and are respectively connected to both sides of the blade mold 100 in the first direction X. The starting mark 11 is located between the two leveling adjustment components 3 and is used to connect with the blade mold 100. The inner cavity of the blade mold 100 is aligned with the edge in the first direction X. Two horizontal adjustment components 3 are connected to the crossbar 1 and are used to adjust the tilt angle of the crossbar 1 with respect to the horizontal plane. An indicator component 4 is disposed between the two horizontal adjustment components 3. The indicator component 4 includes a laser indicator 41 and a first distance measuring device 42. The laser indicator 41 is movably connected to the crossbar 1 along the first direction X. The direction of the laser indicator 41's emission end is perpendicular to the first direction X. The laser indicator 41 is used to indicate a positioning mark on the blade mold 100. The first distance measuring device 42 is used to measure the distance of the laser indicator 41 from the starting mark 11 along the first direction X.

[0027] In the process of producing wind turbine blades using blade mold 100, the opening of the inner cavity of blade mold 100 needs to be set vertically upward so that the air and resin-encased air bubbles in the inner cavity of blade mold 100 can float upward along the direction of gravity and eventually gather at the top opening of the inner cavity of blade mold 100.

[0028] The crossbar 1 can be the basic structure in the positioning device for the wind turbine blade production process, used to support or set other components in the device. By extending the crossbar 1 along the first direction X, making it a rod-shaped structure with a certain length in the first direction X, when the crossbar 1 is placed on the blade mold 100, it can span the opening of the inner cavity of the blade mold 100 along the first direction X. This allows the various devices connected to the crossbar 1 to determine the placement position of the components in the wind turbine blade within the entire inner cavity of the blade mold 100, enabling the positioning device for the wind turbine blade production process to position all components in the wind turbine blade. The first direction X is set to be perpendicular to the extension direction of the blade mold 100.

[0029] The leveling device 2 can be a device used to measure the inclination angle of the crossbar 1 with the horizontal plane. The inclination angle of the crossbar 1 with the horizontal plane can indicate whether the crossbar 1 is placed horizontally. The connection of the leveling device 2 to the crossbar 1 can mean that the leveling device 2 is connected to the portion of the crossbar 1 located in the opening of the inner cavity of the blade mold 100. In some embodiments, the leveling device 2 can be connected to the crossbar 1 by connecting bolts, rivets, or other connecting parts 31.

[0030] For example, the leveling device 2 may include an electronic horizontal tilt sensor, enabling the leveling device 2 to output the tilt angle of the crossbar 1 relative to the horizontal plane in real time.

[0031] The horizontal adjustment assembly 3 can be a set of devices used to adjust the tilt angle between the horizontal bar 1 and the horizontal plane. By adjusting the tilt angle between the horizontal bar 1 and the horizontal plane through the horizontal adjustment assembly 3, the tilt angle between the horizontal bar 1 and the horizontal plane is made within a preset range, so that the horizontal bar 1 can be placed in a horizontal position.

[0032] The two horizontal adjustment components 3 are arranged at a relative interval along the first direction X. This means that there are two horizontal adjustment components 3, which are arranged at a relative interval along the first direction X, so that the two horizontal adjustment components 3 can be located on both sides of the opening of the inner cavity of the blade mold 100 in the first direction X.

[0033] Two horizontal adjustment components 3 are respectively connected to the blade mold 100 on both sides of the first direction X. This means that the two horizontal adjustment components 3 located on both sides of the opening of the inner cavity of the blade mold 100 in the first direction X are respectively connected to the opening of the inner cavity of the blade mold 100 in the first direction X, so that the wind turbine blade production process positioning device can be connected to the blade mold 100 and fixed on the blade mold 100.

[0034] The starting mark 11 can be a mark provided on the crossbar 1 to indicate the position where the crossbar 1 is directly opposite the opening of the inner cavity of the blade mold 100. The starting mark 11 is located between the two horizontal adjustment components 3, which means that the starting mark 11 is provided on the part of the crossbar 1 located between the two horizontal adjustment components 3, so that when the two horizontal adjustment components 3 are connected to the blade mold 100 on both sides of the opening of the inner cavity of the blade mold 100 in the first direction X, the starting mark 11 can be located on the crossbar 1 corresponding to the opening of the inner cavity of the blade mold 100, so as to facilitate the alignment of the starting mark 11 with the edge of the inner cavity of the blade mold 100 in the first direction X.

[0035] By aligning the starting mark 11 with the edge of the inner cavity of the blade mold 100 in the first direction X when the crossbar 1 is connected to the blade mold 100, the relative position of the crossbar 1 and the blade mold 100 can be positioned more accurately.

[0036] Two horizontal adjustment components 3 are connected to the crossbar 1 and used to adjust the tilt angle between the crossbar 1 and the horizontal plane. This means that the horizontal adjustment components 3 connected to both sides of the opening of the inner cavity of the blade mold 100 can adjust the tilt angle between the crossbar 1 and the horizontal plane by adjusting the height of the two ends of the crossbar 1 relative to the blade mold 100.

[0037] The indicator component 4 can be a set of devices used to accurately indicate the position of components in the wind turbine blade at a preset position on the blade mold 100. It should be noted that the setting position of components such as the web in the wind turbine blade is determined by the distance from the inner edge of the blade mold 100.

[0038] By placing the indicator component 4 between the two horizontal adjustment components 3, the indicator component 4 is able to indicate the position within the cavity of the blade mold 100.

[0039] The laser pointer 41 can be a device capable of emitting a spot or beam of light to indicate a positioning mark on the inner cavity of the blade mold 100. The first distance measuring device 42 can be a device for measuring the distance of the laser pointer 41 from the starting mark 11 along the first direction X. In the aforementioned scheme, since the starting mark 11 is aligned with the edge of the inner cavity of the blade mold 100 in the first direction X, the distance of the laser pointer 41 from the starting mark 11 along the first direction X measured by the first distance measuring device 42 is the distance of the laser pointer 41 from the edge of the inner cavity of the blade mold 100 along the first direction X.

[0040] Alternatively, the first distance measuring device 42 can be a laser rangefinder, which is positioned at the starting mark 11. After the laser pointer 41 moves to a preset position, the first distance measuring device 42 can measure the distance of the laser pointer 41 from the starting mark 11 along the first direction X. Alternatively, the first distance measuring device 42 can be connected to the laser pointer 41 and move synchronously. The first distance measuring device 42 measures the distance of the laser pointer 41 from the starting mark 11 along the first direction X by measuring the distance the laser pointer 41 moves relative to the starting mark 11.

[0041] The laser pointer 41 is movably connected to the crossbar 1 along the first direction X. This means that the laser pointer 41 can move along the extension direction of the crossbar 1 so that the laser pointer 41 can indicate different positions in the inner cavity of the blade mold 100.

[0042] The orientation of the laser pointer 41's emitting end is perpendicular to the first direction X. This means that the light emitted by the laser pointer 41 is perpendicular to the first direction X. This makes the distance of the light spot or light ray formed by the light emitted by the laser pointer 41 as a positioning mark from the starting mark 11 in the first direction X equal to the distance of the laser pointer 41 from the starting mark 11 along the first direction X measured by the first distance measuring device 42.

[0043] With the above structure, the positioning device in the wind turbine blade production process can adjust the tilt angle between the crossbar 1 and the horizontal plane through two horizontal adjustment components 3, so that the crossbar 1 is parallel to the horizontal plane. The operator can use the positioning mark shown by the laser indicator 41 in the indicator component 4 to position the blade mold 100 at a preset distance from the starting mark 11 along the first direction X. This makes it convenient for the operator to set or form the components in the wind turbine blade at this location, so that the components in the wind turbine blade can be accurately positioned in the wind turbine blade, which improves the positioning accuracy of each component in the wind turbine blade and helps to improve the quality of the wind turbine blade.

[0044] In some embodiments, the horizontal adjustment assembly 3 includes a connector 31 and an adjustment member 32. The connector 31 is used to connect with the blade mold 100, and the adjustment member 32 is movably connected to the connector 31 along a second direction Y and connected to the crossbar 1. The second direction Y is intersected with the first direction X, and the crossbar 1 is connected to the adjustment member 32.

[0045] The connector 31 may be a component in the leveling assembly 3 used for connecting to the blade mold 100. Exemplarily, the connector 31 may be connected to the blade mold 100 by connecting bolts, by clips, or by connecting hooks. Those skilled in the art may choose the type of connector 31 according to the actual situation.

[0046] The second direction Y can be a direction perpendicular to both the first direction X and the extension direction of the blade mold 100. The adjusting member 32 can drive the end of the crossbar 1 to move in the second direction Y, so as to change the inclination angle of the crossbar 1 with the horizontal plane.

[0047] In some embodiments, continue to refer to Figure 2 The adjusting member 32 includes a first adjusting bolt 321 and a second adjusting bolt 322. The first adjusting bolt 321 and the second adjusting bolt 322 are connected to the connecting member 31 by threads. The connecting member 31 extends along the second direction Y. The crossbar 1 is clamped between the first adjusting bolt 321 and the second adjusting bolt 322.

[0048] The first adjusting bolt 321 and the second adjusting bolt 322 are two adjusting bolts that are spaced apart from each other along the second direction Y. The first adjusting bolt 321 and the second adjusting bolt 322 are connected to the connecting member 31 by threads, and the connecting member 31 is configured to extend along the second direction Y, so that the first adjusting bolt 321 and the second adjusting bolt 322 can be moved along the second direction Y by screwing.

[0049] By clamping the crossbar 1 between the first adjusting bolt 321 and the second adjusting bolt 322, the movement of the first adjusting bolt 321 and the second adjusting bolt 322 on the connector 31 can drive the end of the crossbar 1 to move along the second direction Y, thereby changing the tilt angle of the crossbar 1 relative to the horizontal plane.

[0050] For example, the crossbar 1 is provided with a through hole extending along the second direction Y, the connector 31 passes through the through hole, and the first adjusting bolt 321 and the second adjusting bolt 322 clamp the crossbar 1 from both sides of the crossbar 1 in the second direction Y.

[0051] In some embodiments, continue to refer to Figure 3 The adjusting component 32 includes a clamping bolt 323, and the connecting component 31 includes a rod 311 and a connecting portion 312. The rod 311 extends along the second direction Y, and the connecting portion 312 is connected to the end of the rod 311. The connecting portion 312 is used to connect with the blade mold 100. The clamping bolt 323 is located on the side of the crossbar 1 away from the connecting portion 312 and is connected to the connecting component 31 by threads. The inner cavity of the blade mold 100 is provided with a boss 101 facing the opening of the inner cavity at the edge of the first direction X. The horizontal adjusting component 3 is provided on the outer side of the boss 101 away from the inner cavity. The clamping bolt 323 of one of the two horizontal adjusting components 3 can adjust the tilt angle of the crossbar 1 with the horizontal plane by pressing the part of the crossbar 1 away from the inner cavity in the first direction X.

[0052] The clamping bolt 323 can be a bolt used to press down the crossbar 1. The boss 101 can be a protruding structure that protrudes outward along the direction of the opening of the inner cavity of the blade mold 100 at the edge of the inner cavity in the first direction X. By providing a boss 101 that protrudes along the direction of the opening of the inner cavity at the edge of the inner cavity of the blade mold 100 in the first direction X, the boss 101 forms a fulcrum at the edge of the inner cavity of the blade mold 100 in the first direction X, so that when the crossbar 1 is located on the boss 101, one end can be pressed down by the clamping bolt 323 while the other end is raised, thereby realizing the adjustment of the tilt angle of the crossbar 1 with the horizontal plane.

[0053] The rod 311 can be the main structure of the connector 31, extending along the second direction Y. The connecting part 312 can be a structural part of the connector 31 for connecting with the blade mold 100, connected to the end of the rod 311, so that the end of the connector 31 in the second direction Y can be connected to the blade mold 100. By providing the clamping bolt 323 on the side of the crossbar 1 away from the connecting part 312 and connecting it to the connector 31 by threads, the clamping bolt 323 can be moved by rotation along the extending direction (second direction Y) of the connector 31.

[0054] By setting the horizontal adjustment component 3 on the outside of the inner cavity opening of the boss 101 away from the blade mold 100 in the first direction X, the clamping bolt 323 of one of the two horizontal adjustment components 3 can be used to lift the crossbar 1 by pressing the part of the crossbar 1 away from the inner cavity in the first direction X, thereby adjusting the tilt angle of the crossbar 1 with respect to the horizontal plane.

[0055] In some embodiments, the indicating component 4 further includes a base 43, which is movably connected to the crossbar 1 along a first direction X, and the laser indicator 41 and the first distance measuring device 42 are both connected to the base 43.

[0056] The base 43 can be a structure in the indicating assembly 4 used to support and mount other devices. By connecting both the laser pointer 41 and the first distance measuring device 42 to the base 43, the first distance measuring device 42 and the laser pointer 41 can move synchronously.

[0057] The seat 43 is movably connected to the crossbar 1 along the first direction X, which means that the seat 43 is connected to the crossbar 1 and can move along the extension direction of the crossbar 1 (the first direction X).

[0058] For example, the first distance measuring device 42 includes a magnetic grating displacement sensor, which includes a magnetic strip disposed on the crossbar 1 and a reading head disposed on the seat 43. The reading head senses the periodic change of the magnetic field as it moves along the crossbar 1 with the seat 43, and the counting pulses are converted into walking displacement and cumulative distance.

[0059] In some embodiments, the movable connection between the seat 43 and the crossbar 1 can be achieved by having a rack on the crossbar 1 and a drive motor on the seat 43. The output end of the drive motor meshes with the rack through a gear. The operator controls the movement of the seat 43 on the crossbar 1 by controlling the rotation of the drive motor, so that the seat 43 and the laser pointer 41 connected to the seat 43 move along the crossbar 1.

[0060] In some embodiments, continue to refer to Figure 4 The seat 43 is slidably connected to the crossbar 1. The positioning device for the wind turbine blade production process also includes a drive assembly 5. The drive assembly 5 includes a drive pulley 51, a driven pulley 52, and a transmission belt 53. The transmission belt 53 is tractively connected to the drive pulley 51 and the driven pulley 52. ​​The transmission belt 53 is connected to the seat 43. The drive pulley 51 and the driven pulley 52 are rotatably connected to the crossbar 1 and are respectively located on both sides of the inner cavity opening in the first direction X. Under the drive of the drive pulley 51, the transmission belt 53 can drive the seat 43 to slide along the crossbar 1.

[0061] By sliding the seat 43 to the crossbar 1, the seat 43 can move along the crossbar 1 under the action of external force, so that a positioning mark can be shown at any position in the first direction X in the inner cavity of the blade mold 100.

[0062] The drive assembly 5 can be a set of devices for driving the seat 43 to slide along the crossbar 1. By rotatably connecting both the drive pulley 51 and the driven pulley 52 to the crossbar 1, and drivingly connecting the transmission belt 53 to the drive pulley 51 and the driven pulley 52, the drive pulley 51 can drive the transmission belt 53 to move, thereby driving the seat 43 connected to the transmission belt 53 to slide along the crossbar 1.

[0063] By setting the drive pulley 51 and the driven pulley 52 on both sides of the inner cavity opening in the first direction X, the seat 43 can pass through the inner cavity opening of the blade mold 100 along the first direction X under the drive of the transmission belt 53.

[0064] For example, the drive pulley 51 can be connected to the output end of the drive motor. The operator controls the movement of the seat 43 on the crossbar 1 by controlling the rotation of the drive motor, and then controls the laser indicator 41 to show the position of the positioning mark in the inner cavity of the blade mold 100.

[0065] In some embodiments, the indicating component 4 further includes a display 44, which is communicatively connected to the first distance measuring device 42 and displays the distance measured by the first distance measuring device 42. The drive pulley 51 is provided with a crank.

[0066] The display 44 can be a device for displaying the measurement results of the first distance measuring device 42. It is communicatively connected to the first distance measuring device 42 and can display the measurement results of the first distance measuring device 42 in real time. By providing a crank on the drive pulley 51, the operator can rotate the drive pulley 51 by cranking the crank, so that the seat 43 can move along the crossbar 1 under the manual drive of the operator.

[0067] Through the above scheme, the staff can adjust the position of the seat 43 on the crossbar 1 in a timely manner according to the measurement results of the first distance measuring device 42 displayed on the display 44, so that the laser indicator 41 on the seat 43 can accurately reach the preset position at a preset distance from the starting mark 11 in the first direction X, so as to show the positioning mark at the preset position in the inner cavity of the blade mold 100, so as to set the components in the wind turbine blade such as the web at that location.

[0068] In some embodiments, the crossbar 1 is provided with a distance scale 12, which starts from the starting mark 11 and is located on the side of the starting mark 11 away from the horizontal adjustment component 3 along the first direction X.

[0069] The distance scale 12 can be a scale provided on the crossbar 1 to display the distance from the starting mark 11 along the first direction X. By starting the distance scale 12 at the starting mark 11 and setting the distance scale 12 on the side of the starting mark 11 away from the horizontal adjustment component 3 along the first direction X, the distance scale 12 can accurately show the distance from the starting mark 11 to the crossbar 1 located at the opening of the inner cavity of the blade mold 100.

[0070] Using the above method, the staff can compare the result measured by the first distance measuring device 42 with the distance from the laser indicator 41 to the starting mark 11 shown on the distance scale 12, so as to calibrate the first distance measuring device 42.

[0071] In some embodiments, the laser pointer 41 is provided with a distance measurement module, and the measuring end of the distance measurement module is oriented perpendicular to the first direction X.

[0072] The distance measurement module can be used to measure distances. By setting the orientation of the measuring end of the distance measurement module to be perpendicular to the first direction X, the distance measurement module is able to measure the distance of the positioning mark from the laser pointer 41 in the direction perpendicular to the first direction X.

[0073] By integrating a distance measurement module into the laser pointer 41, the laser pointer 41 is equipped with the function of measuring the distance of the positioning mark from the laser pointer 41 in the direction perpendicular to the first direction X. This enables the laser pointer 41 to monitor the dimensions of components such as the web set in the inner cavity of the blade mold 100 in the direction perpendicular to the first direction X, which helps to improve the quality of wind turbine blades.

[0074] This application also provides a positioning method for wind turbine blade manufacturing process. This method utilizes the positioning device provided by any of the above technical solutions to determine the placement of components within a wind turbine blade. The positioning method includes: S1. Install the crossbar 1, place the crossbar 1 on the blade mold 100 and span the opening of the inner cavity of the tablet mold, the crossbar 1 is connected to the blade mold 100 through the horizontal adjustment assembly 3, wherein the starting mark 11 of the crossbar 1 is aligned with the edge of the inner cavity of the blade mold 100 in the first direction X.

[0075] In step S1 above, by placing the crossbar 1 on the blade mold 100 and spanning the opening of the inner cavity of the tablet mold, the crossbar 1 is connected to the blade mold 100 through the horizontal adjustment component 3, and part of the crossbar 1 can be firmly positioned at the opening of the inner cavity of the tablet mold.

[0076] S2. Adjust the angle by adjusting the tilt angle between the horizontal bar 1 and the horizontal plane to the preset range using the horizontal adjustment component 3.

[0077] In step S2 above, the tilt angle between the horizontal bar 1 and the horizontal plane is adjusted to a preset range by the horizontal adjustment component 3, so that the horizontal bar 1 can be identified as being in a horizontal state, which helps to improve the accuracy of the subsequent positioning of components in the wind turbine blade.

[0078] For example, the preset range of the inclination angle A between the crossbar 1 and the horizontal plane can be -0.1°≤A≤0.1°.

[0079] S3. Positioning component: Move laser pointer 41 to first position along first direction X. First distance measuring device 42 measures that the distance from the first position to the starting mark 11 along first direction X reaches a preset distance. The positioning mark shown by laser pointer 41 on blade mold 100 is the setting position of component in wind turbine blade.

[0080] In step S3 above, by moving the laser pointer 41 to a first position at a distance of a preset distance from the starting mark 11 along the first direction X, the positioning mark shown by the laser pointer 41 at the first position in the inner cavity of the blade mold 100 is at a preset distance from the starting mark 11 along the first direction X. This allows components such as the web of the wind turbine blade to be accurately positioned at a preset distance from the opening edge of the inner cavity of the blade mold 100 along the first direction X by setting the positioning mark.

[0081] The above method enables the components in the wind turbine blade to be accurately positioned within the blade, improving the positioning accuracy of each component and contributing to the improvement of the quality of the wind turbine blade.
