Description

Technical Field

[0001] This application relates to the field of wind power generation technology, and in particular to a tooling for measuring the width of the web assembly of a wind turbine blade and a wind turbine blade. Background Technology

[0002] In the field of modern wind power technology, wind turbine blades are a key component, and many adopt a double-web structure, meaning two webs are spaced apart along the blade width and extend along the blade length. Accurately measuring the distance between the web pairs (the outer sides of the two webs) is crucial during blade manufacturing and installation, and this distance must meet certain dimensional standards. In actual measurement, the distance between the two webs needs to be measured at regular intervals. Workers typically attempt to measure from above the webs using measuring tools. However, because the cross-section of the webs is I-shaped, existing measuring tools are ill-suited to this unique shape, making effective and accurate measurement impossible. Therefore, currently, simple measurements are commonly performed manually using a measuring tape. This method, due to human factors and limitations of measuring tools, suffers from significant measurement errors and cannot meet the high-precision manufacturing and installation requirements of wind turbine blades. Utility Model Content

[0003] To address at least one of the problems mentioned in the background art, this application provides a tooling for measuring the width of the web assembly of a wind turbine blade and a wind turbine blade, which can improve measurement accuracy.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] In a first aspect, this application provides a tooling for measuring the width of the web assembly of a wind turbine blade, including a tooling body, an abutment plate and a push rod. The tooling body has a C-shaped frame structure, and the opening of the C-shaped frame structure of the tooling body includes a first end and a second end opposite to each other.

[0006] The contact plate is fixedly connected to the first end, and the push rod is slidably connected to the second end. The push rod has a scale that indicates the amount of displacement of the push rod relative to the contact plate. The width of the web plate assembly can be measured by adjusting the distance between the first end of the push rod and the contact plate.

[0007] As an optional implementation, an adjusting block is also included, which is movably disposed at the second end of the tooling body, and the push rod is slidably connected to the adjusting block.

[0008] As an optional implementation, a guide cylinder is also included, which is mounted on the adjusting block, and the push rod passes through the guide cylinder.

[0009] As an optional implementation, a handle is also included, which is disposed at the second end of the push rod.

[0010] As an optional implementation, a limiting flange is also included, which is disposed at the first end of the push rod.

[0011] As an optional implementation, a preload spring is also included, which is sleeved on the first end of the push rod, and the two ends of the preload spring elastically abut against the ends of the limiting flange and the guide cylinder, respectively.

[0012] As an optional implementation, both the surface of the contact plate and the end face of the first end of the push rod have anti-slip textures.

[0013] As an alternative implementation, the push rod cross-section is circular or square.

[0014] As an optional implementation, the tooling body, the contact plate, and the push rod are all made of carbon fiber composite material.

[0015] Secondly, this application also provides a wind turbine blade, including the wind turbine blade web assembly width measuring fixture described in the first aspect.

[0016] The wind turbine blade web assembly width measuring fixture provided in this application includes a fixture body, a contact plate, and a push rod. The fixture body has a C-shaped frame structure, and the opening of the C-shaped frame structure of the fixture body includes a first end and a second end opposite to each other. The contact plate is fixedly connected to the first end, and the push rod is slidably connected to the second end. The push rod has a scale, which is used to indicate the displacement of the push rod relative to the contact plate, so as to measure the width of the web assembly by adjusting the distance between the first end of the push rod and the contact plate.

[0017] The wind turbine blade web assembly width measuring fixture provided in this application allows for the measurement of web assembly width by first inserting the C-shaped opening of the fixture body between the two webs from above, with the contact plate abutting against the outer side of one web. Then, by controlling a push rod, one end of the push rod gradually approaches and conforms to the outer side of the other web. At this point, the scale on the push rod clearly and accurately displays the displacement of the push rod relative to the contact plate, which is the distance between the two webs. Compared with existing technologies, this measurement method avoids measurement deviations caused by inaccurate positioning and reading errors when manually pulling a measuring tape, greatly improving measurement accuracy. Furthermore, the fixture has a simple structure, is easy to operate, and can quickly measure the web spacing, effectively improving work efficiency and reducing measurement costs.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0037] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0040] Accurately measuring the distance between the web assembly (the outer sides of the two webs) is crucial during blade manufacturing and installation, and this distance must meet certain dimensional standards. In practice, the distance between the two webs needs to be measured at regular intervals. Workers typically attempt to measure this distance from above the webs using measuring tools. However, due to the I-shaped cross-section of the webs, existing measuring tools are ill-suited to this unique shape, making effective and precise measurement impossible. Therefore, currently, a simple measurement method using a measuring tape is commonly used. This method, however, is susceptible to significant measurement errors due to human factors and limitations of the measuring tools.

[0041] In view of this, this application provides a tooling for measuring the width of wind turbine blade web assembly, including a tooling body, a contact plate, and a push rod. The tooling body has a C-shaped frame structure, and the opening of the C-shaped frame structure includes a first end and a second end facing each other. The contact plate is fixedly connected to the first end, and the push rod is slidably connected to the second end. The push rod has a scale indicating the displacement of the push rod relative to the contact plate. When measuring the width of the web assembly, the C-shaped opening of the tooling body can be first inserted between the two webs from above, so that the contact plate abuts against the outside of one of the webs. Then, by controlling the push rod, one end of the push rod gradually approaches and fits against the outside of the other web. At this time, the scale on the push rod can intuitively and accurately display the displacement of the push rod relative to the contact plate, that is, the distance between the two webs. Compared with the prior art, this measurement method avoids the measurement deviation caused by human factors such as inaccurate positioning and reading errors when manually pulling a measuring tape, and greatly improves the measurement accuracy.

[0042] Figure 1 This is a first schematic diagram of a tooling for measuring the width of a wind turbine blade web assembly provided in an embodiment of this application. Figure 2 This is a second schematic diagram of the wind turbine blade web assembly width measuring fixture provided in the embodiments of this application; Figure 3 This is a schematic diagram of the wind turbine blade web assembly width measuring fixture provided in this application embodiment when measuring the width of the web assembly.

[0043] You can refer to this. Figures 1 to 3 This application provides a tooling 100 for measuring the width of a pair of web plates 200 of a wind turbine blade, including a tooling body 110, a contact plate 120, and a push rod 130. The tooling body 110 has a C-shaped frame structure, and the opening 111 of the C-shaped frame structure of the tooling body 110 includes a first end and a second end opposite to each other. The contact plate 120 is fixedly connected to the first end, and the push rod 130 is slidably connected to the second end. The push rod 130 has a scale, which is used to indicate the displacement of the push rod 130 relative to the contact plate 120, so that the width of the pair of web plates 200 can be measured by adjusting the distance between the first end of the push rod 130 and the contact plate 120.

[0044] The wind turbine blade web 200 pair width measuring fixture 100 provided in this application embodiment can measure the pair width of the web 200 by first inserting the C-shaped opening 111 of the fixture body 110 into the two webs 200 from above, so that the contact plate 120 abuts against the outside of one of the webs 200. Then, by controlling the push rod 130, one end of the push rod 130 gradually approaches and fits against the outside of the other web 200. At this time, the scale on the push rod 130 can intuitively and accurately display the displacement of the push rod 130 relative to the contact plate 120, that is, the distance between the two webs 200. Compared with the prior art, this measurement method avoids the measurement deviation caused by human factors such as inaccurate positioning and reading errors when manually pulling a measuring tape, and greatly improves the measurement accuracy. Moreover, the fixture has a simple structure, is easy to operate, and can quickly measure the distance between the webs 200, effectively improving work efficiency and reducing measurement costs.

[0045] In the above embodiments, an adjusting block 140 may also be included. The adjusting block 140 is movably disposed at the second end of the tooling body 110, and the push rod 130 is slidably connected to the adjusting block 140. It can be understood that the adjusting block 140 being movably disposed at the second end of the tooling body 110 and the push rod 130 being slidably connected to the adjusting block 140 allows the tooling to adjust the distance between the adjusting block 140 and the web 200 as the initial distance. Since the push rod 130 itself has a limited adjustment range, by pre-adjusting the initial distance, the tooling can adapt to a wider range of web types 200. For example, when encountering webs 200 with large spacing, the adjusting block 140 can be moved to a suitable position to increase the initial distance, and then the push rod 130 can be used for fine-tuning and measurement, thereby overcoming the limitation of the push rod 130's own adjustment range and meeting the measurement needs of webs 200 of different specifications. After reasonably setting the initial distance, the push rod 130 performs relative movement measurement on the adjusting block 140. This design allows the movement of the push rod 130 to be more targeted and precise. The initial distance provides an adjusted base position for measurement. Subsequent push rods 130 only need to be precisely adjusted within a small range, reducing the error accumulation that may occur due to large-range adjustments and helping to improve the final measurement accuracy.

[0046] During actual measurement, operators can flexibly adjust the position of the adjusting block 140 according to the specific conditions of the web 200 to determine the appropriate initial distance. Compared to relying solely on the push rod 130 to adjust the measurement range, this method of first coarsely adjusting the initial distance and then finely adjusting the push rod 130 is simpler and faster. Operators can more intuitively prepare for measurements based on different web 200 conditions, improving the overall efficiency of the measurement work. This design enhances the adaptability of the tooling to different working conditions and the structure of the web 200. Whether facing a new blade model or measuring in a complex installation site, the initial distance can be flexibly changed through the adjusting block 140, allowing the tooling to quickly adapt to new measurement tasks. This reduces the need to change different measuring tools due to differences in the web 200, lowers measurement costs, and improves the versatility and practicality of the tooling.

[0047] In the above embodiments, a guide cylinder 150 may also be included. The guide cylinder 150 is mounted on the adjusting block 140, and the push rod 130 passes through the guide cylinder 150. The guide cylinder 150, mounted on the adjusting block 140 and through which the push rod 130 passes, provides a fixed guiding path for the sliding of the push rod 130. This strictly limits the direction of movement of the push rod 130, ensuring that the push rod 130 always slides smoothly in a direction perpendicular to the end face of the contact plate 120. This avoids problems such as offset or tilting of the push rod 130 during measurement, structurally ensuring the consistency of the measurement reference and solving the measurement error caused by the deviation of the sliding direction of the push rod 130 when there is no guiding structure. The guide cylinder 150 and the push rod 130 form a suitable sliding fit, reducing the frictional resistance when the push rod 130 slides, and avoiding wear or jamming caused by direct contact between the push rod 130 and the adjusting block 140, making the movement of the push rod 130 smoother and more stable. This design ensures that the push rod 130 can move at a constant speed when it is in contact with the outer side of the web 200, avoiding problems such as loose contact and inaccurate readings caused by sliding and jamming, and further improving the smoothness and reliability of the measurement operation.

[0048] In addition, the guide cylinder 150 also serves as an isolation and protection mechanism, preventing direct friction and collision between the push rod 130 and the adjusting block 140, reducing the wear on both, and extending the service life of the push rod 130 and the adjusting block 140. At the same time, the structural design of the guide cylinder 150 ensures that the tooling maintains stable guiding performance and sliding accuracy even after long-term repeated use, reducing the problem of decreased tooling accuracy due to component wear, and improving the overall durability and ease of maintenance of the tooling.

[0049] In the above embodiments, a handle 160 may also be included, which is disposed at the second end of the push rod 130. It is understood that the handle 160, disposed at the second end of the push rod 130, provides the operator with a clear and comfortable point of force application. Compared to directly pushing the end of the push rod 130, the force applied by hand is more concentrated and less strenuous. When repeatedly measuring along the blade length direction, the operator does not need to repeatedly search for the point of force application; they can quickly grasp the handle 160 to push or pull the push rod 130, achieving precise contact and repositioning of the push rod 130 with the outer side of the web 200, significantly improving the efficiency of the measurement operation and reducing hand fatigue caused by prolonged measurement. By controlling the moving speed and stroke of the push rod 130 through the handle 160, fine-tuning of the push rod 130 can be achieved. The staff can sense the contact force between the push rod 130 and the outer side of the web plate 200 through the handle 160, avoiding excessive force or insufficient contact caused by directly operating the push rod 130. This ensures that the push rod 130 stops moving when it is just in contact with the outer side of the web plate 200, making the scale reading closer to the actual distance and further optimizing the accuracy of the measurement.

[0050] In the above embodiments, a limiting flange 170 may also be included, which is disposed at the first end of the push rod 130. It is understood that the diameter of the limiting flange 170 is larger than the inner diameter of the guide cylinder 150 (or the sliding hole diameter of the adjusting block 140), forming a mechanical limiting structure. This effectively prevents the push rod 130 from detaching from the guide cylinder 150 or the adjusting block 140 during sliding adjustment due to improper operation (such as excessive pulling), avoiding the scattering or damage of tooling components. It also prevents measurement interruptions or safety hazards caused by the push rod detaching, improving the reliability and safety of the tooling. The limiting flange 170, disposed at the first end of the push rod 130, increases the contact area between the push rod 130 and the outer side of the web 200. Compared to the push rod 130 being directly attached to its end, it can more smoothly and tightly abut against the outer wall of the web 200, making the measurement reference of the push rod 130 more stable, and thus making the correspondence between the scale reading and the actual distance of the web 200 more accurate.

[0051] In addition, the limiting flange 170 provides a clear indication of the end of the fit for the operator. When the flange end face is fully fitted with the outer side of the web 200, it can be determined that the push rod 130 has reached the measurement reference position, eliminating the need for additional judgment on the degree of fit and reducing the problem of excessively tight or loose fit caused by differences in operating experience. Especially when performing repeated measurements along the blade length, it ensures the consistency of operation at each measurement point, further guaranteeing the uniformity of multiple sets of measurement data.

[0052] In the above embodiments, a preload spring 180 may also be included. The preload spring 180 is sleeved on the first end of the push rod 130, and the two ends of the preload spring 180 elastically abut against the ends of the limiting flange and the guide cylinder 150, respectively. It can be understood that during measurement, pulling the push rod 130 causes the limiting flange 170 to conform to the outer side of the web 200. The preload spring 180 is compressed, generating a reverse elastic force. This force ensures that the limiting flange 170 always maintains a stable pressure against the surface of the web 200, avoiding problems of excessively loose or tight contact due to uneven manual force application. Stable contact pressure ensures consistent surface contact between the push rod 130 and the outer side of the web 200, reducing measurement errors caused by contact gaps or pressure fluctuations, and further guaranteeing measurement accuracy. Secondly, the elastic properties of the preload spring 180 can act as a buffer, preventing the limiting flange 170 from rigidly colliding with the surface of the web 200 when the push rod 130 is pushed to fit against the web 200. This reduces the risk of impact damage to the surface coating or body structure of the web 200. At the same time, it can also buffer the instantaneous force applied by the hand during operation, preventing the push rod 130 from excessively squeezing the web 200 or the tooling parts from being damaged due to excessive force. This balances measurement safety and component protection.

[0053] Furthermore, the preload spring 180 can cooperate with the limiting flange 170, and the spring force always pushes the limiting flange 170 away from the guide cylinder 150, ensuring that the limiting flange 170 will not accidentally move close to the guide cylinder 150 when not measuring, further enhancing the anti-disengagement function of the limiting flange 170. At the same time, the elastic constraint of the spring can also reduce the random sliding of the push rod 130 when not measuring, maintain the stability of the tooling structure, and avoid collision and wear between the push rod 130 and other components during transportation or when idle.

[0054] In the above embodiments, both the surface of the contact plate 120 and the end face of the first end of the push rod 130 can have anti-slip texture 190. The anti-slip texture of the contact plate 120 and the end face of the first end of the push rod 130 effectively increases the contact friction between them and the outer wall of the web 200, preventing relative sliding between the end faces of the contact plate 120 and the push rod 130 and the web 200 due to slight tool displacement, hand force fluctuations, or slight oil stains or smooth coatings on the surface of the web 200 during measurement. The increased friction ensures a stable fit between the tool and the web 200 during measurement, eliminating measurement errors caused by sliding deviation at the contact level. The anti-slip texture 190 increases the engagement during contact, allowing the end faces of the contact plate 120 and the push rod 130 to more firmly engage with the outer side of the web 200. Especially when measuring at different angles and positions along the blade length, the anti-slip texture 190 ensures that the contact position and force state are consistent each time the blade is fitted, making the correspondence between the displacement of the push rod 130 and the actual distance between the web plate 200 more accurate, and ensuring the consistency and reliability of multiple sets of measurement data.

[0055] Secondly, during measurement, after the operator pushes the push rod 130 to fit against the web plate 200, the stable friction provided by the anti-slip texture 190 reduces the reliance on continuous force. The tooling can maintain its contact without additional force, allowing the operator to focus on reading the scale values ​​and avoiding operational errors caused by simultaneously needing to fix the tooling and read the values. Furthermore, in complex measurement scenarios such as at heights or in confined spaces, the contact stability provided by the anti-slip texture 190 reduces the risk of the tooling accidentally slipping, improving operational safety.

[0056] In addition, the surface of the wind turbine blade web 200 may have slight unevenness or rough coating. The anti-slip texture 190 is designed to adapt to such complex surface conditions. The textured structure forms multiple points of contact with the web 200 surface. Even if the web 200 surface is uneven, the interlocking effect of the anti-slip texture 190 can ensure an effective contact area, avoiding problems of poor adhesion caused by differences in surface conditions, and enhancing the adaptability of the tooling in actual production scenarios.

[0057] In the above embodiments, the cross-section of the push rod 130 can be circular or square. The circular cross-section push rod 130 has lower sliding resistance, fits the circular hole structure of the guide cylinder 150, allows for smooth rotational adjustment, and facilitates fine-tuning of the contact position. The circular cross-section push rod 130 experiences uniform force, exhibits excellent bending and torsional resistance, and is not easily deformed during long-term sliding use. The circular push rod 130 also allows for slight angle adjustments when holding the handle 160, adapting to different measurement postures. The square cross-section push rod 130 restricts circumferential rotation, preventing scale deviation caused by the push rod 130's self-rotation during measurement, ensuring consistent reading references. The square cross-section push rod 130 provides stronger contact stability when in contact with the web plate 200, distributing force and preventing component damage caused by localized stress concentration. Because the square push rod 130 has no risk of self-rotation, the scale markings remain clearly visible, facilitating quick reading of values ​​by operators. These two shapes adapt to different guide structures and usage requirements, broadening the applicability of the tooling. Furthermore, both circular and square shapes are conventional cross-sectional shapes, with mature processing technology and low cost. They are easy to precisely match with the guide cylinder 150 and the adjusting block 140, reducing the difficulty of tooling production and manufacturing. No complex positioning structure is required during assembly, and the push rod 130 can be quickly assembled with each component, improving tooling production efficiency.

[0058] In the above embodiments, the tooling body 110, the contact plate 120, and the push rod 130 can all be made of carbon fiber composite material. It is understood that carbon fiber composite material has a much lower density than traditional metal materials, significantly reducing the overall weight of the tooling. During measurement, workers can easily carry and frequently move the tooling, especially in scenarios involving multiple measurements along the blade length or high-altitude operations, greatly reducing hand fatigue and operational burden, and improving measurement flexibility and work efficiency. Furthermore, carbon fiber composite material possesses high strength and high rigidity, and its mechanical properties can meet the force requirements during measurement, preventing deformation of the tooling during pushing, fitting, and other operations. Even with long-term repeated use, it can maintain stable structural accuracy, ensuring that the measurement benchmark does not deviate and guaranteeing the consistency of measurement data. Secondly, carbon fiber composite material has excellent corrosion resistance and aging resistance, resisting the effects of environmental humidity and slight chemical media at the wind turbine blade manufacturing site, avoiding the problems of rust and corrosion common in traditional metal tooling. At the same time, its strong wear resistance reduces wear caused by friction between components, extending the overall service life of the tooling and reducing maintenance and replacement costs.

[0059] In addition, the material itself has a low coefficient of thermal expansion and is less affected by changes in ambient temperature. This can prevent slight deformation of the tooling dimensions due to temperature fluctuations, ensuring that the relative position accuracy of the contact plate 120 and the push rod 130 remains stable under different operating conditions. This further reduces measurement errors caused by environmental factors and meets the high precision requirements of wind turbine blade manufacturing.

[0060] Furthermore, this application embodiment also provides a wind turbine blade, including the wind turbine blade web 200 pair width measuring fixture 100 in the above embodiment. The wind turbine blade web 200 pair width measuring fixture 100 includes a fixture body 110, a contact plate 120, and a push rod 130. The fixture body 110 has a C-shaped frame structure, and the opening 111 of the C-shaped frame structure of the fixture body 110 includes a first end and a second end opposite to each other. The contact plate 120 is fixedly connected to the first end, and the push rod 130 is slidably connected to the second end. The push rod 130 has a scale, which is used to indicate the displacement of the push rod 130 relative to the contact plate 120. When measuring the width of the web plates 200, the C-shaped opening 111 of the fixture body 110 can be first inserted between the two web plates 200 from above, so that the contact plate 120 abuts against the outside of one of the web plates 200. Then, by controlling the push rod 130, one end of the push rod 130 is gradually moved closer to and fit against the outside of the other web plate 200. At this time, the scale on the push rod 130 can intuitively and accurately show the displacement of the push rod 130 relative to the contact plate 120, that is, the distance between the two web plates 200. Compared with the existing technology, this measurement method avoids the measurement deviation caused by human factors such as inaccurate positioning and reading errors when manually pulling a measuring tape, which greatly improves the measurement accuracy and the reliability of wind turbine blades.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
