[0037] Wind turbine blades are the core components of wind turbines, used to capture wind energy and convert it into mechanical energy, which is then converted into electrical energy through the generator in the wind turbine. Wind turbine blades usually include a shell and a main beam inside the shell. With the iteration of wind turbine blades, the main beam has gradually developed into a pultruded main beam formed by combining pultruded plates. After the pultruded main beam is formed, it is placed in the shell and poured as a whole.

[0038] In order to transport the formed pultruded main beam into the shell, a follower and a binding belt are usually used. After the binding belt passes around the bottom of the pultruded main beam, the follower is used to tighten the binding belt to achieve the binding of the follower and the binding belt to the pultruded main beam, and then the pultruded main beam is transported by the lifting equipment. However, the above binding method is prone to cause the pultruded plates to stack and misalign during the lifting process, resulting in damage to the pultruded main beam, which in turn affects the reliability of the formed blades.

[0039] In view of this, the tensioning device of the main beam of the wind turbine blade provided in the present application is used for bundling the pultruded main beam of the wind turbine blade, and the tensioning device includes a follow-up mechanism, a supporting assembly and an adjusting mechanism. The follow-up mechanism has a predetermined length, and the supporting assembly is arranged on the follow-up mechanism and enclosed with the follow-up mechanism to form a fixed cavity. By setting the fixed cavity, the pultruded main beam is placed between the follow-up mechanism and the supporting assembly. The supporting assembly includes a rigid supporting member and a first connecting member, and the rigid supporting member is rotatably connected to the first end of the follow-up mechanism through the first connecting member. The rigid supporting member is located below the pultruded main beam to achieve rigid support for the pultruded main beam. By manipulating the adjusting mechanism, the rigid supporting member is driven to move relative to the follow-up mechanism to achieve the adjustment of the fixed cavity volume, and then the follow-up mechanism and the rigid supporting member are bundled with the pultruded main beam. In this way, in the process of lifting and transporting the pultruded main beam, the rigid supporting member supports the pultruded main beam, so as to avoid stacking and dislocation between the pultruded plates, so as to avoid damage to the pultruded main beam.

[0040] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] See also Figures 1 to 5 The present application provides a tensioning device for a main beam of a wind turbine blade, which is used for bundling the pultruded main beam of a wind turbine blade. The tensioning device may include a conforming mechanism 100, a supporting assembly 200 and an adjusting mechanism 400.

[0042] The form-fitting mechanism 100 has a predetermined length, and the form-fitting mechanism 100 has a first end 110 and a second end 120 opposite to each other along its length direction X. The supporting assembly 200 is arranged on the form-fitting mechanism 100 and encloses the form-fitting mechanism 100 to form a fixed cavity 300, and the fixed cavity 300 is used to accommodate the pultruded main beam. The supporting assembly 200 includes a rigid supporting member 210 and a first connecting member 220. In the length direction X, one end of the rigid supporting member 210 is rotatably connected to the first end 110 through the first connecting member 220, and the other end of the rigid supporting member 210 and the second end 120 are detachably arranged to open or close the fixed cavity 300.

[0043] The rigid supporting member 210 may be made of a material having a tensile strength between 173-244 MPa and a hardness between 120-160 HB. Optionally, the rigid supporting member 210 may include an aluminum alloy supporting plate.

[0044] The follower mechanism 100 has a predetermined length. In a specific implementation, the length of the follower mechanism 100 in the length direction X can be set according to the width of the pultruded main beam to meet the requirements of pultruded main beams of different sizes. Along the length direction X, the follower mechanism 100 has a first end 110 and a second end 120 opposite to each other. The first end 110 and the second end 120 provide a basis for the connection between the follower mechanism 100 and the supporting assembly 200.

[0045] The adaptable mechanism 100 may include a solid plate structure, or a hollow frame structure. Optionally, the adaptable mechanism 100 may include an arc structure. In addition, the material of the adaptable mechanism 100 may include at least one of steel, aluminum alloy, and titanium alloy, so that the adaptable mechanism 100 has sufficient rigidity and strength to bear the weight of the pultruded main beam during the lifting process.

[0046] In order to effectively support and fix the pultruded main beam, the tensioning device is provided with a supporting assembly 200. The supporting assembly 200 and the follow-up mechanism 100 together enclose a fixed cavity 300, and the fixed cavity 300 is used to accommodate and fix the pultruded main beam. Specifically, the supporting assembly 200 may include a rigid supporting member 210 and a first connecting member 220. In the length direction X, one end of the rigid supporting member 210 is rotatably connected to the follow-up mechanism 100, and the other end is detachably connected to the follow-up mechanism 100. This arrangement allows the staff to open or close the fixed cavity 300 by manipulating the rigid supporting member 210, so as to facilitate the placement and removal of the pultruded main beam.

[0047] The first connecting member 220 may include one of a hook, a hinge, and a rotating sleeve.

[0048] A groove may be provided on one of the conformable mechanism 100 and the supporting assembly 200, and when the two cooperate, they can enclose a fixed cavity. Of course, in some implementations, grooves may also be provided on both the conformable mechanism 100 and the supporting assembly 200, and when the two cooperate, they can enclose a fixed cavity to ensure that the fixed cavity 300 is used to accommodate and fix the pultruded main beam.

[0049] In order to achieve effective tensioning of the pultruded main beam in the fixed cavity 300, the tensioning device is further provided with an adjustment mechanism 400. The adjustment mechanism 400 is connected to the follower mechanism 100 and at least a part of the rigid support member 210, and through the driving action, the rigid support member 210 is prompted to move relative to the follower mechanism 100, thereby adjusting the volume of the fixed cavity 300, and can also be accurately adjusted according to the actual size and tensioning requirements of the pultruded main beam, thereby ensuring the shape of the pultruded main beam while ensuring the binding of the follower mechanism 100 and the rigid support member 210 to the pultruded main beam.

[0050] The adjustment mechanism 400 may include one of a tensioner, an electric push rod, and an electric lift.

[0051] For example, when bundling the pultruded main beam, the staff can first place the follow-up mechanism 100 on top of the pultruded main beam, and then rotate the rigid supporting member 210 so that the pultruded main beam is located in the fixed cavity 300 enclosed by the rigid supporting member 210 and the follow-up mechanism 100, and then operate the adjusting mechanism 400 to adjust the volume of the fixed cavity 300, that is, to enable the follow-up mechanism 100 and the rigid supporting member 210 to bundle the pultruded main beam together. In this way, in the process of lifting and transporting the pultruded main beam, compared with the soft support formed by bundling the pultruded main beam with a binding belt in the related art, the rigid support of the pultruded main beam by the rigid supporting member 210 can avoid stacking and misalignment between the pultruded plates, thereby avoiding damage to the pultruded main beam.

[0052] In actual use, multiple tensioning devices can be used to bind the pultruded main beam together. Optionally, the spacing between each tensioning device can be set to 2m to 4m to enhance the binding effect of the pultruded main beam and avoid stacking and misalignment between the pultruded plates.

[0053] See also Figure 1 and Figure 2 In some embodiments, an open groove 130 is provided on the side of the profile-adapting mechanism 100 facing the rigid supporting member 210. Along the length direction X, the groove width of the open groove 130 is greater than the length of the rigid supporting member 210. The rigid supporting member 210 can extend into the open groove 130. The adjustment mechanism 400 drives the rigid supporting member 210 to move along the groove depth direction Z of the open groove 130, and the groove depth direction Z intersects with the length direction X.

[0054] When the staff places the follow-up mechanism 100 on the pultrusion main beam, the pultrusion main beam slides into the open groove 130 to abut against the side of the follow-up mechanism 100 facing the rigid supporting member 210. By setting the open groove 130 to limit the two sides of the pultrusion main beam in the width direction, the follow-up mechanism 100 and the pultrusion main beam can be prevented from sliding against each other.

[0055] In specific implementation, the opening groove 130 extends along the length direction X of the profile-adapting mechanism 100, and the groove width of the opening groove 130 is set to be greater than the length of the rigid supporting member 210. This arrangement ensures that the rigid supporting member 210 can extend into the opening groove 130 without hindrance, and under the drive of the adjustment mechanism 400, it can flexibly move along the groove depth direction Z of the opening groove 130, thereby more effectively adjusting the volume of the fixed cavity 300 and ensuring that the main beam always maintains a stable posture and stress state during the pultrusion process.

[0056] Optionally, the intersection angle between the groove depth direction Z and the length direction X can be selected to be 90°, that is, they can be selected to be perpendicular to each other.

[0057] See also Figure 2In some embodiments, the side of the rigid supporting member 210 facing the flexible mechanism 100 includes a first arcuate surface 211 , and the first arcuate surface 211 is recessed in a direction away from the fixing cavity 300 .

[0058] It should be noted that, by providing the first curved surface 211 , the rigid supporting member 210 can better fit with the pultruded main beam during actual use, thereby ensuring that the rigid supporting member 210 provides stable support to the pultruded main beam.

[0059] In addition, the first arc surface 211 is concave in the direction away from the fixing cavity 300, which increases the contact area between the rigid support member 210 and the pultruded main beam to a certain extent. Such a configuration helps to disperse stress and improve the overall bearing capacity and stability of the rigid support member 210. At the same time, it also provides a more uniform and reliable support for the pultruded main beam, which helps to improve the performance and reliability of the tensioning device.

[0060] Optionally, the curvature of the first curved surface 211 can be set according to actual requirements of the pultruded main beam, and the present application is not limited thereto.

[0061] It can be understood that the side of the conformable mechanism 100 facing the rigid supporting member 210 may include a second curved surface 180, and the second curved surface 180 may be protruded toward the fixed cavity 300. In this way, in actual use, the conformable mechanism 100 and the rigid supporting member 210 may fit more closely with the pultruded main beam, which helps to improve the binding effect of the tensioning device on the pultruded main beam.

[0062] See also Figure 1 In some embodiments, the first end portion 110 is provided with a second connecting member 111, the first connecting member 220 is detachably connected to the second connecting member 111, and the first connecting member 220 and the rigid supporting member 210 are rotatably connected to each other.

[0063] The connection between the first connecting member 220 and the second connecting member 111 is designed to be detachable, so that the rigid supporting member 210 and the flexible mechanism 100 can be quickly assembled or disassembled when needed, thereby improving the convenience and flexibility of operation.

[0064] Matching with the first connecting member 220, the second connecting member 111 may include one of a hanging rod, a hinge seat, and a rotating shaft.

[0065] It can be understood that the first connecting member 220 and the rigid supporting member 210 are rotatably connected to each other, so that the rigid supporting member 210 can rotate freely within a certain range, thereby being able to better adapt to different angle requirements, thereby improving the flexibility and adaptability of the rigid supporting member 210 to better support the pultruded main beam.

[0066] The first connecting member 220 and the rigid supporting member 210 may include a hinge connection to achieve the rotation between the first connecting member 220 and the rigid supporting member 210, which is not limited in the present application.

[0067] See also Figure 1 In some embodiments, the attachable mechanism 100 includes a support member 140, a first attachable plate 150 and a second attachable plate 160, the first attachable plate 150 and the second attachable plate 160 are arranged opposite to each other in a first direction Y, the first attachable plate 150 and the second attachable plate 160 are fixedly connected by the support member 140, the first attachable plate 150 and the second attachable plate 160 include a first end 110 and a second end 120, and a second connecting member 111 is connected between the first attachable plate 150 and the second attachable plate 160; wherein the first direction Y intersects with the length direction X.

[0068] The first direction Y can be selected as the width direction of the conforming mechanism 100, and can also be understood as the length direction X of the pultruded main beam.

[0069] It should be noted that the first conformal plate 150 and the second conformal plate 160 are arranged relative to each other in the first direction Y, and a predetermined spacing can be set between the first conformal plate 150 and the second conformal plate 160. In this way, it is ensured that the first conformal plate 150 and the second conformal plate 160 can work together to tighten the pultruded main beam together with the rigid supporting member 210, thereby further avoiding stacking and misalignment between the pultruded plates.

[0070] In order to stably connect the first conformable plate 150 and the second conformable plate 160 , the conformable mechanism 100 may include a support member 140 . The support member 140 not only serves as a bridge connecting the first conformable plate 150 and the second conformable plate 160 , but also provides necessary support force for the entire conformable mechanism 100 .

[0071] The support member 140 may include a support block, a support rod, a support frame and other structural forms. The number of the support members 140 may be one or more. When there are more than one support members 140, the multiple support members may be distributed along the length direction.

[0072] It can be understood that the second connecting member 111 is connected between the first conformal plate 150 and the second conformal plate 160, which not only facilitates the connection between the first connecting member 220 and the second connecting member 111, but also enhances the connection strength between the first conformal plate 150 and the second conformal plate 160. Figure 1 In some embodiments, the first conforming plate 150 and the second conforming plate 160 are respectively provided with limiting portions 170 at both ends in the length direction X, and the limiting portions 170 are located on the side of the first conforming plate 150 and the second conforming plate 160 facing the rigid supporting member 210 .

[0073] Exemplarily, the limiting portion 170 may include at least one of structures such as a limiting baffle and a limiting column.

[0074] By setting the limiting part 170, the pultruded main beam can be limited in the length direction X of the conforming mechanism 100. During the lifting and transportation process, the pultruded main beam can be prevented from sliding relative to the conforming mechanism 100, thereby ensuring the structural integrity of the pultruded main beam.

[0075] See also Figure 1 , Figure 4 and Figure 5 In some embodiments, the adjustment mechanism 400 includes a tensioning component 410 and a binding member 420. The tensioning component 410 is disposed on the flexible mechanism 100. The tensioning component 410 is connected to the binding member 420 and can retract and release the binding member 420. The binding member 420 is wrapped around the side of the flexible mechanism 100 and the rigid supporting member 210 that are away from each other.

[0076] In actual operation, when the relative position or tension between the conformable mechanism 100 and the rigid support member 210 needs to be adjusted, the tensioning assembly 410 will start and drive the binding member 420 to perform the corresponding retraction and extension action. By accurately controlling the retraction and extension of the binding member 420, the tensioning assembly 410 can effectively adjust the volume of the fixed cavity 300 between the conformable mechanism 100 and the rigid support member 210 to achieve the binding and relaxation of the pultruded main beam.

[0077] The tensioning assembly 410 may include one of a hydraulic tensioner, a ratchet 412 tensioner, and a pneumatic tensioner. The binding member 420 may include a binding belt.

[0078] See also Figure 1 and Figure 2 In some embodiments, the tensioning assembly 410 includes a rotating shaft 411, a ratchet 412 and a stopper 413, wherein the rotating shaft 411 is rotatably connected to the first conformal plate 150 and the second conformal plate 160 in sequence along the first direction Y; the ratchet 412 is sleeved on the rotating shaft 411, and the stopper 413 is connected to the first conformal plate 150, and the stopper 413 is used to abut against the tooth groove of the ratchet 412, wherein the ratchet 412 and the stopper 413 are both located on the side of the first conformal plate 150 away from the second conformal plate 160.

[0079] It should be noted that when the rotating shaft 411 is operated to rotate in the direction of tightening the binding member 420, the ratchet 412 can rotate synchronously with the rotation of the rotating shaft 411. The tooth groove of the ratchet 412 cooperates with the stopper 413, so that the ratchet 412 rotates in one direction in the direction of tightening the binding member 420 and is locked in the opposite direction, effectively preventing the rotating shaft 411 from rotating in the reverse direction, and ensuring the durability of the tightening effect.

[0080] Optionally, the stopper 413 may include a stop pin, and the stopper 413 may be arranged to be rotatably connected to the first follower plate 150. The first follower plate 150 may be provided with an anti-slipping member 151, and the stopper 413 is located between the first follower plate 150 and the anti-slipping member 151. When it is necessary to tighten the binding member 420, the anti-slipping member 151 is tightened to fix the stopper 413, so that the stopper 413 abuts against the ratchet 412 to prevent the ratchet 412 from rotating in the reverse direction. When it is necessary to loosen the binding member 420, the anti-slipping member 151 is loosened to allow the stopper 413 to rotate relative to the first follower plate 150, thereby releasing the abutment between the stopper 413 and the ratchet 412, so that the ratchet 412 and the rotating shaft 411 can rotate in the reverse direction, so as to realize the disassembly of the binding member 420. Compared with the related art of cutting off the binding member 420 to achieve the purpose of disassembling the binding member 420, the tensioning assembly 410 provided in the present application can realize the reuse of the binding member 420, thereby saving resources and reducing costs.

[0081] The anti-dropping member 151 may be a bolt threadedly connected to the first conforming plate 150 .

[0082] See also Figure 1 and Figure 4 In some embodiments, the tensioning components 410 are arranged in pairs, and the tensioning components 410 arranged in pairs are respectively located at both ends of the conformable mechanism 100 in the length direction X; the tensioning components 410 arranged in pairs each include a fixing portion 414, and the fixing portion 414 is arranged in a one-to-one correspondence with the rotating shaft 411, one of the two fixing portions 414 is arranged at one end of the rotating shaft 411 close to the first conformable plate 150, and the other is arranged at one end of the rotating shaft 411 close to the second conformable plate 160, and the fixing portion 414 is used to fix the end of the binding member 420.

[0083] By locating the tensioning components 410 at both ends of the conformable mechanism 100 in the length direction X, it is ensured that the conformable mechanism 100 can distribute stress more evenly when subjected to force, thereby avoiding damage to the conformable mechanism 100 caused by excessive force at a single point.

[0084] In a specific implementation, each of the tensioning components 410 arranged in pairs is provided with a fixing portion 414, so that the ends of the binding member 420 can be effectively and firmly fixed. In addition, the two fixing portions 414 are respectively arranged at one end of the rotating shaft 411 close to the first conforming plate 150 and the second conforming plate 160, which not only facilitates the installation and tensioning operation of the binding member 420, but also ensures that the binding member 420 can maintain a stable tension during the tensioning process without loosening or falling off.

[0085] Optionally, the fixing portion 414 may be a fixing groove provided on the rotating shaft 411 .

[0086] See also Figure 1 In some embodiments, the support assembly 200 further includes a handpiece 230 , which is fixedly connected to the rigid support member 210 .

[0087] The hand piece 230 provides a more convenient means of control for the staff. The hand piece 230 fixedly connected to the rigid support member 210 enables the staff to apply force through the hand piece 230 when carrying, adjusting or fixing the support assembly 200, thereby reducing the difficulty of operation and improving work efficiency.

[0088] The hand piece 230 is provided to enhance the stability and safety of the support assembly 200. The fixed connection between the hand piece 230 and the rigid support member 210 ensures that the support assembly 200 is not easy to slip during transportation or adjustment, thereby avoiding possible safety hazards.

[0089] It should be noted that the handpiece 230 can adopt a curved surface design that conforms to the contour of the hand, as well as a non-slip and wear-resistant material to ensure that the staff can maintain a comfortable feel and stable grip during operation.

[0090] See also Figure 1 In some embodiments, the tensioning device further includes a hoisting portion 500, which is connected to at least one of the conforming mechanism 100 and the adjusting mechanism 400, and the hoisting portion 500 is used to connect to the lifting equipment.

[0091] It can be understood that the hoisting portion 500 enhances the stability and safety of the tensioning device during transportation and installation.

[0092] Optionally, the lifting part 500 may include a hook rod arranged between the first conforming plate 150 and the second conforming plate 160 or on the rotating shaft 411, so that the hook of the lifting equipment is cooperated and connected with the hook rod to ensure that the tensioning device can remain stable during the lifting process and is not prone to shaking or falling off.
