Among them, the beam structure is the main load-bearing structure of the wind turbine blade. At present, pultruded beams are usually used as the beam structure of wind turbine blades. Pultruded beams have strong bending and torsion resistance and can meet the strength requirements of wind turbine blades.

[0003] However, pultruded beams also have certain defects. Since the beam structure of a pultruded beam is made of multiple pultruded plates stacked together, the misalignment between different pultruded plates will cause steps on the side of the beam structure and a certain angle between the side and bottom of the beam structure. After the skin layer is laid, the beam structure of the pultruded beam will also change the beam edge angle and step depth, thereby affecting the matching of the beam edge core material and the pultruded beam edge angle, and further affecting the overall strength of the pultruded beam.

[0039] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0040] In the manufacture of wind turbine blades, pultruded beams are usually used as the beam structure of wind turbine blades. While pultruded beams can meet the strength requirements of wind turbine blades, they also have certain defects. Since the beam structure of the pultruded beam is made of multiple pultruded plates stacked together, the misalignment between different pultruded plates will cause steps on the side of the beam structure, and will also cause a certain beam edge angle between the side and bottom of the beam structure, thereby affecting the matching of the beam edge core material and the pultruded beam edge angle, resulting in the resin-rich defect of the beam edge, which affects the bending and torsional performance of the blade.

[0041] In addition, after the pultruded beam structure is formed, it is necessary to lay a skin on its upper or lower surface.

[0042] After the skin is laid on one side of the beam structure, the beam edge angle and step depth will also change, thus affecting the matching of the beam edge core material and the pultruded beam edge angle, and further affecting the overall strength of the pultruded beam.

[0043] In order to ensure the production quality of the pultruded beam, it is necessary to measure the beam edge angle and step depth of the beam structure before and after laying the skin to observe the data fluctuation. At present, angle measuring devices and depth measuring devices are usually used for measurement respectively, but this measurement method requires multiple measuring tools to cooperate with the measurement, and multiple measurements are required. The measurement cycle is long and the overall measurement efficiency is low. In addition, the common measuring device cannot accurately measure the beam structure before and after laying the skin. In addition, after the skin is laid on the surface of the beam structure, the overall area of ​​the skin is larger than the upper and lower surface areas of the beam structure. When measuring the beam edge angle and step depth of the beam structure after laying the skin, it will be affected by the skin, so that accurate measurement cannot be performed. In response to the above problems, the embodiment of the present application provides a pultruded beam measurement device, which can synchronously measure the beam edge angle and step depth of the pultruded beam, and can accurately measure the beam edge angle and step depth of the beam structure before and after laying the skin, thereby improving the measurement efficiency and measurement accuracy.

[0044] like Figures 1 to 5 As shown, an embodiment of the present application provides a pultruded beam measuring device, which includes a first measuring piece 10 having a preset length; a second measuring piece 20, rotatably connected to the first measuring piece 10, the second measuring piece 20 having a first supporting surface 21 adapted to the first surface 111 of the piece to be measured 100; a rotating measuring piece 30, arranged at the rotational connection between the first measuring piece 10 and the second measuring piece 20, the rotating measuring piece 30 is used to detect the rotation angle of the second measuring piece 20; a depth measuring piece 40, movably mounted on the first measuring piece 10, for measuring the piece to be measured 100 in the length direction of the first measuring piece 10 and in its orthogonal direction; an auxiliary measuring piece 50, detachably mounted on the second measuring piece 20, having a second supporting surface 51 adapted to the second surface 121 of the piece to be measured 100.

[0045] It should be noted that the test piece 100 in the embodiment of the present application can be divided into two states: before laying the skin and after laying the skin. Before laying the skin, Figure 1 and Figure 4 As shown, the test piece 100 only includes a main body structure 110, which is a beam structure. The main body structure 110 has a first surface 111 and a side surface 112. The first surface 111 is the top or bottom surface of the main body structure 110. Since the main body structure 110 is made of a plurality of pultruded plates stacked together, a plurality of steps 113 with different depths are formed on the side surface 112. The depth direction of the step 113 is the direction from the side surface 112 to the inside of the main body structure 110. After laying the skin, as shown in FIG. Figure 4As shown, the test piece 100 includes a main body structure 110 and a protective structure 120. The protective structure 120 is a skin laid on the top surface or the bottom surface of the main body structure 110. The second surface 121 is the surface of the protective structure 120 facing the main body structure 110. Since the overall area of ​​the protective structure 120 is large, most of the second surface 121 does not overlap with the main body structure 110.

[0046] In specific implementation, the pultruded beam measuring device of the embodiment of the present application includes a first measuring piece 10, a second measuring piece 20, a rotating measuring piece 30, a depth measuring piece 40 and an auxiliary measuring piece 50. The second measuring piece 20 is rotatably connected to the first measuring piece 10 with a preset length. When measuring the beam structure waiting to be measured piece 100, the first surface 111 of the piece to be measured 100 is attached to the first supporting surface 21 of the second measuring piece 20, and the side surface 112 of the piece to be measured 100 is attached to the first measuring piece 10. At this time, the piece to be measured 100 is arranged as a whole between the angle between the first measuring piece 10 and the second measuring piece 20. The rotating measuring piece 30 can measure the angle generated by the rotation between the first measuring piece 10 and the second measuring piece 20, so as to obtain the beam side angle of the piece to be measured 100, and at the same time, the depth of multiple steps of the piece to be measured 100 can be measured by moving the depth measuring piece 40 on the first measuring piece 10.

[0047] like Figure 4 As shown, after the test piece 100 is covered with a skin, it has a second surface 121. The auxiliary measuring piece 50 with a second supporting surface 51 can be installed on the second measuring piece 20, and the overall structure of the second measuring piece 20 and the auxiliary measuring piece 50 can be rotated so that the second measuring piece 20 and the auxiliary measuring piece 50 are located on the other side of the first measuring piece 10 as a whole. At this time, the second supporting surface 51 can fit on the second surface 121 of the protective structure 120, and the side surface 112 of the test piece 100 can fit on the first measuring piece 10. At this time, the test piece 100 with the skin is disposed as a whole between the angle between the first measuring piece 10 and the second measuring piece 20. The rotating measuring piece 30 and the depth measuring piece 40 can respectively measure the beam edge angle and step depth of the test piece 100 with the skin. Therefore, the pultruded beam measuring device of the present application can perform angle measurement and depth measurement at the same time, so that the beam edge angle and step depth of the pultruded beam can be synchronously measured, and the beam edge angle and step depth of the beam structure before and after laying the skin can be accurately measured, thereby improving the measurement efficiency and measurement accuracy.

[0048] like Figure 1 As shown, when measuring the test piece 100 before laying the skin, the rotation angle between the first measuring piece 10 and the second measuring piece 20 measured by the rotating measuring piece 30 is the angle between the first surface 111 and the side surface 112 of the main body structure 110, that is, the beam edge angle of the test piece 100; Figure 4As shown, when measuring the test piece 100 with a skin, the rotation angle between the first measuring piece 10 and the second measuring piece 20 measured by the rotating measuring piece 30 is the angle between the second surface 121 of the protective structure 120 and the side surface 112 of the main body structure 110. This angle is actually complementary to the beam edge angle. After the measurement, this angle needs to be calculated and processed to obtain the accurate beam edge angle.

[0049] like Figure 1 and Figure 3 As shown, a pultruded beam measuring device according to an embodiment of the present application is provided, wherein a rotating measuring member 30 is sequentially inserted through the end of a first measuring member 10 and the end of a second measuring member 20 , and the rotating measuring member 30 is rotationally connected to at least one of the first measuring member 10 and the second measuring member 20 .

[0050] When the rotating measuring member 30 rotates between the first measuring member 10 and the second measuring member 20 , the rotating measuring member 30 can measure the rotation angle of the two, thereby measuring the angle generated between the two.

[0051] In addition, the rotating measuring piece 30 is sequentially inserted into the end of the first measuring piece 10 and the end of the second measuring piece 20, that is, the end of the first measuring piece 10 is rotationally connected to the end of the second measuring piece 20. When measuring the beam edge angle of the piece to be measured 100 after laying the skin, it can avoid the end of the first measuring piece 10 protruding from the second supporting surface 51 of the second measuring piece 20, so that the second supporting surface 51 can be completely attached to the second surface 121 of the piece to be measured 100, thereby ensuring the accurate measurement of the beam edge angle.

[0052] Specifically, the rotating measuring piece 30 is a cylindrical structure, the second measuring piece 20 is fixedly connected to one end of the rotating measuring piece 30, and the first measuring piece 10 is rotatably mounted on the outer circumference of the rotating measuring piece 30. When angle measurement is required, the rotating measuring piece 30 is rotated to drive the second measuring piece 20 to rotate together. During the rotation process, the rotating measuring piece 30 can perform real-time angle measurement and calculation, thereby realizing the measurement of the beam edge angle.

[0053] Optionally, the first measuring piece 10 can be fixedly connected to one end of the rotating measuring piece 30, and the second measuring piece 20 can be rotatably mounted on the outer circumference of the rotating measuring piece 30; or both the first measuring piece 10 and the second measuring piece 20 can be rotatably mounted on the outer circumference of the rotating measuring piece 30, and the rotating measuring piece 30 can simultaneously detect the rotation angles of the first measuring piece 10 and the second measuring piece 20.

[0054] like Figure 1 and Figure 2As shown, the pultruded beam measuring device further includes a display 60, which is communicatively connected with the rotating measuring member 30 and is used to display the angle between the first measuring member 10 and the second measuring member 20. The display 60 is installed at the end of the first measuring member 10 away from the second measuring member 20. After measuring and calculating the angle between the first measuring member 10 and the second measuring member 20, the rotating measuring member 30 can transmit the angle to the display 60 and display the effect on the display 60, so as to facilitate the user to read the angle of the beam edge.

[0055] The pultruded beam measuring device of the embodiment of the present application, wherein the auxiliary measuring piece 50 has a snap-in groove 52, which is recessed on the surface opposite to the second supporting surface 51, and the second measuring piece 20 is snap-connected with the auxiliary measuring piece 50 through the snap-in groove 52; wherein, when the second measuring piece 20 and the auxiliary measuring piece 50 are assembled, the first supporting surface 21 of the second measuring piece 20 is abutted against the bottom of the snap-in groove 52, and the second supporting surface 51 is in contact with the second surface 121 of the piece to be measured 100.

[0056] During specific implementation, a portion of the second measuring piece 20 can be snapped into the inside of the snap-in groove 52 of the auxiliary measuring piece 50, so that the auxiliary measuring piece 50 is installed on the second measuring piece 20, and the snap-in groove 52 is recessed on the surface opposite to the second supporting surface 51, so that when the second measuring piece 20 and the auxiliary measuring piece 50 are assembled, the second measuring piece 20 is assembled on the surface opposite to the second supporting surface 51, and its first supporting surface 21 is abutted against the bottom of the snap-in groove 52, which will not affect the fit between the second supporting surface 51 and the second surface 121, thereby ensuring the measurement accuracy of the pultruded beam measuring device for the beam edge angle.

[0057] Optionally, the second measuring piece 20 may include a protrusion whose shape matches the snap-fit ​​groove 52, and the first supporting surface 21 may be the top surface of the protrusion. The second measuring piece 20 is snap-fitted with the snap-fit ​​groove 52 through its protrusion to ensure the connection stability between the second measuring piece 20 and the auxiliary measuring piece 50, thereby avoiding relative movement between the second measuring piece 20 and the auxiliary measuring piece 50 during the measurement process, which would affect the measurement accuracy of the beam edge angle.

[0058] Another embodiment of the present application is a pultruded beam measuring device, wherein the auxiliary measuring piece 50 has a plug-in portion, which is provided at the end of the auxiliary measuring piece 50, and the auxiliary measuring piece 50 is plug-in-matched with the end of the second measuring piece 20 away from the first measuring piece 10 through the plug-in portion; wherein, when the second measuring piece 20 and the auxiliary measuring piece 50 are assembled, the first supporting surface 21 is spaced apart from the second surface 121 of the piece to be measured 100, and the second supporting surface 51 is in contact with the second surface 121 of the piece to be measured 100.

[0059] During specific implementation, the plug-in portion of the auxiliary measuring piece 50 is plugged into the end of the second measuring piece 20, and the plug-in fit can ensure both the connection stability and the assembly efficiency between the two.

[0060] In this embodiment, the overall thickness of the auxiliary measuring piece 50 needs to be greater than the overall thickness of the second measuring piece 20. When the two are assembled, the first supporting surface 21 can be spaced apart from the second surface 121 of the piece to be measured 100, and the second supporting surface 51 can be in contact with the second surface 121 of the piece to be measured 100, thereby avoiding the first supporting surface 21 from being in contact with the second surface 121 of the piece to be measured 100 during the measurement process, thereby affecting the measurement accuracy of the beam edge angle.

[0061] like Figure 5 As shown, the pultruded beam measuring device of an embodiment of the present application, wherein the auxiliary measuring piece 50 also has a recessed portion 53, the recessed portion 53 is arranged at the end of the auxiliary measuring piece 50, the surface of the recessed portion 53 is a recessed arc surface, and the arc surface is adapted to the shape of the outer peripheral surface of the rotating measuring piece 30.

[0062] In a specific implementation, when the engaging groove 52 of the auxiliary measuring piece 50 is engaged with the second measuring piece 20, the recessed portion 53 of the arc-shaped surface can avoid the rotating measuring piece 30, so that when the overall structure of the auxiliary measuring piece 50 and the second measuring piece 20 is rotated, there is no interference between the auxiliary measuring piece 50 and the rotating measuring piece 30, thereby ensuring the measurement efficiency and measurement accuracy of the pultruded beam measuring device.

[0063] like Figure 1 and Figure 2 As shown, a pultruded beam measuring device according to an embodiment of the present application is provided with a slide rail 11 and a scale 12 on the first measuring piece 10, and the extension directions of the slide rail 11 and the scale 12 are the same as the extension direction of the first measuring piece 10; the depth measuring piece 40 includes a connected mounting seat 41 and a measuring scale 42, the mounting seat 41 can be slidably mounted on the slide rail 11, and the extension direction of the measuring scale 42 is perpendicular to the extension direction of the first measuring piece 10.

[0064] During specific implementation, the mounting seat 41 can slide in the extension direction of the slide rail 11 to measure the position of different steps to measure the depth of the step 113, and the sliding position of the mounting seat 41 can be judged by the scale 12 parallel to the slide rail 11, so as to determine whether the measuring ruler 42 connected to the mounting seat 41 has reached the position of the step 113 to be measured. The measuring ruler 42 also has a scale. When measuring the depth of the step 113, the specific depth value of the step 113 can also be obtained by reading the scale value of the measuring ruler 42.

[0065] like Figure 2As shown, a pultruded beam measuring device according to an embodiment of the present application has a sliding hole 411 extending therethrough inside the mounting seat 41, the opening direction of the sliding hole 411 is perpendicular to the extension direction of the first measuring piece 10, and the measuring ruler 42 is slidably installed in the sliding hole 411.

[0066] In a specific implementation, the measuring ruler 42 can be slidably installed in the sliding hole 411. Since the opening direction of the sliding hole 411 is perpendicular to the extension direction of the first measuring member 10, the measuring ruler 42 can slide along its extension direction. When measuring the depth of the step 113, the measuring ruler 42 can be slid until its end abuts against the side of the step 113, thereby facilitating stable reading of the measuring ruler 42 to ensure the measurement accuracy of the depth of the step 113.

[0067] like Figure 6 As shown, the embodiment of the present application further provides a pultruded beam measurement method, wherein the measurement method performs a measurement operation through the pultruded beam measurement device described above, including:

[0068] S110, attaching the side surface 112 of the main structure 110 of the test piece 100 to the first test piece 10;

[0069] Since a plurality of steps 113 are formed on the side surface 112 of the main body structure 110, the side surface 112 is an inclined surface as a whole. When the side surface 112 is entirely attached to the measuring surface of the first measuring member 10, the side surface 112 can be parallel to the extending direction of the first measuring member 10.

[0070] S120, rotating the second measuring member 20 until the first supporting surface 21 thereof is in contact with the first surface 111 of the main body structure 110, and reading the first angle detected by the rotating measuring member 30;

[0071] According to the position of the first surface 111 of the main body structure 110, the second measuring piece 20 is rotated so that the first supporting surface 21 of the second measuring piece 20 can be completely attached to the first surface 111. At this time, the first angle between the second measuring piece 20 and the first measuring piece 10 is the same as the angle between the side surface 112 of the main body structure 110 and the first surface 111. Therefore, by reading the first angle detected by the rotating measuring piece 30, the beam edge angle of the unskinned piece 100 to be tested can be directly obtained.

[0072] S130, moving the depth measuring member 40 on the first measuring member 10 to measure a first height and a first depth of each step 113 on the side surface 112;

[0073] In this step, the first height and the first depth of each step 113 measured are the height and the depth of the step 113 of the test piece 100 without skinning, wherein the height direction is perpendicular to the depth direction;

[0074] S140, installing the auxiliary measuring member 50 on the second measuring member 20;

[0075] During the installation of the auxiliary measuring member 50 on the second measuring member 20, it is necessary to insert the side of the second measuring member 20 having the first supporting surface 21 into the clamping groove 52 of the auxiliary measuring member 50, and make the first supporting surface 21 abut against the bottom of the clamping groove 52, so as to complete the installation of the auxiliary measuring member 50 and avoid the auxiliary measuring member 50 and the second measuring member 20 from being separated during the measurement process.

[0076] S150, moving and rotating the second measuring member 20 until the second supporting surface 51 of the auxiliary measuring member 50 is in contact with the second surface 121 of the protective structure 120 of the object to be measured 100, and reading the second angle detected by the rotating measuring member 30;

[0077] This step includes:

[0078] S151, rotating the second measuring member 20 until the second measuring member 20 and the main body structure 110 are located at opposite sides of the first measuring member 10;

[0079] After the test piece 100 is covered with a skin, that is, after the test piece 100 has a main body structure 110 and a protective structure 120, the second surface 121 of the protective structure 120 is in contact with the first surface 111 of the main body structure 110, and the overall area of ​​the second surface 121 is larger than the first surface 111. The second measuring piece 20 cannot be in contact with the first surface 111 to directly measure the beam side angle of the main body structure 110. Therefore, the second measuring piece 20 needs to be rotated to the other side of the first measuring piece 10 to measure the angle between the protective structure 120 and the main body structure 110, so as to calculate the beam side angle of the main body structure 110.

[0080] S152, moving the pultruded beam measuring device to make the first measuring piece 10 fit the side surface 112 of the piece to be measured 100;

[0081] S153, rotating the second measuring member 20 again, so that the second supporting surface 51 is in contact with the second surface 121 of the protection structure 120;

[0082] The first measuring piece 10 is attached to the side surface 112 of the object to be measured 100, and the second measuring piece 20 is rotated until its second supporting surface 51 is attached to the second surface 121 of the protective structure 120, so that the second angle between the first measuring piece 10 and the second measuring piece 20 is equal to the angle between the side surface 112 of the object to be measured 100 and the second surface 121 of the protective structure 120. At this time, the second angle detected by the rotating measuring piece 30 is read, and the complementary angle of the beam side angle of the main structure 110 can be obtained. Through further complementary calculation, the accurate beam side angle can be obtained.

[0083] S160, moving the depth measuring member 40 on the first measuring member 10 to measure the second height and the second depth of each step 113 on the side surface 112;

[0084] In this step, the second height and the second depth of each step 113 measured are the height and the depth of the step 113 of the test piece 100 after the skin is laid, wherein the height direction is perpendicular to the depth direction.

[0085] The pultruded beam measurement method of the embodiment of the present application, wherein the step of moving the depth measuring member 40 on the first measuring member 10 specifically includes:

[0086] The mounting seat 41 of the depth measuring member 40 is moved along the extension direction of the slide rail 11 of the first measuring member 10, so that the measuring ruler 42 mounted on the mounting seat 41 is opposite to the step 113 to be measured in the extension direction of the first measuring member 10, and the first height or the second height of the step 113 is measured;

[0087] By moving the mounting seat 41 of the depth measuring member 40, the measuring ruler 42 can be moved together with the mounting seat 41, so that it reaches the position of the step 113 to be measured in the extension direction of the first measuring member 10. Therefore, the sliding setting of the mounting seat 41 facilitates the position adjustment of the measuring ruler 42 in the extension direction of the first measuring member 10.

[0088] Slide the measuring ruler 42 in the sliding hole 411 of the mounting seat 41 along the orthogonal direction of the first measuring member 10 to complete the measurement of the first depth or the second depth of the step 113;

[0089] By providing the sliding hole 411, the measuring ruler 42 can be easily slid in its extension direction. When measuring the first depth or the second depth of the step 113, the measuring ruler 42 can be slid until its end abuts against the side surface of the step 113, thereby facilitating stable reading of the measuring ruler 42 to ensure the measurement accuracy of the depth of the step 113.
