Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade production, and in particular to a modular wind turbine blade trailing edge component bonding profile retaining device and a working method. Background Art

[0002] Wind turbine blades are an important part of wind turbines. Their design and manufacturing have a vital impact on the efficiency and performance of wind turbines. Blades are usually made of composite materials to achieve a combination of high strength and low weight. Modular wind turbine blades divide long blades into several independent modules, which are spliced ​​and assembled on site to solve the difficulties encountered in transporting and installing extra-long blades. The structural design of the blades includes leading edge components, trailing edge components, box components, main beams, etc.

[0003] like Figure 1 As shown, before the rear edge component and the box body component are spliced, adhesive needs to be applied to the bonding area, and then the rear edge component is moved chordally to bond with the box body component. During the bonding process, in order to ensure the bonding quality and control the thickness of the glue layer (the thickness affects the mechanical properties of the glue), a large external force needs to be applied to combine the two.

[0004] like Figure 2 As shown, since the trailing edge component is in the form of an opening and the bonding area is relatively weak, it is easy to cause deformation, affecting the outer contour of the blade. The force diagram of the specific area of ​​the trailing edge component includes the bonding area, the weak area and the cavity area. In order to effectively protect each area, it is necessary to constrain its surface to prevent it from deformation; the external constraint is relatively easy to achieve on the assembly tool (pressing down), but for the internal surface constraint, due to the particularity of the structure of the trailing edge component of the blade, the space inside the cavity of the trailing edge component is relatively small. After the trailing edge component is bonded to the box component, the surface constraint set inside the trailing edge component, such as the top extension / limiting mechanism, cannot be manually removed, which brings difficulties to the splicing of the trailing edge component and the box component.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0006] The present invention provides a modular wind turbine blade trailing edge component bonding profile retaining device and a working method, thereby effectively solving the problems pointed out in the background technology.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A modular wind turbine blade trailing edge component bonding profile retaining device, comprising: internal profile constraint modules sequentially arranged at intervals along the axial direction of the trailing edge component;

[0009] The internal profile constraint module is arranged in the cavity area of ​​the trailing edge component, and is used to support the bonding area, the weak area and the cavity area of ​​the trailing edge component;

[0010] The internal profile constraint module comprises two aligned support plates and a control assembly for controlling the folding of the two support plates; a hinge is provided between the two support plates, and the control assembly drives the two support plates to rotate along the hinge, and the appearance of the two support plates in the unfolded state is adapted to the cavity area of ​​the trailing edge component;

[0011] The control assembly includes a fixed rod, an elastic member, a slider, a support rod and a force-applying end, wherein the fixed rod is vertically arranged with the support plate in the expanded state, an elastic member and the slider are arranged on a side of the fixed rod away from the support plate, the slider slides along the fixed rod, and the elastic member is used for resetting the slider;

[0012] The two support rods are symmetrically arranged along the length direction of the fixed rod, one end of the support rod is hinged to the support plate, and the other end is hinged to the slider;

[0013] The force-applying end is arranged on a side of the fixing rod away from the support plate. The force-applying end is subjected to force to cause the slider to slide along the fixing rod, and the two support rods respectively drive the two support plates to rotate along the hinge to the side away from the control component; when the force-applying end is cancelled, the elastic member drives the slider to return to its original position, thereby driving the two support plates to return to their original position.

[0014] Furthermore, it also includes an adjustment ring, which is arranged on the fixing rod, and the adjustment ring is arranged at one end of the elastic member away from the slider. The adjustment ring moves on the fixing rod and is fixed at any position of the fixing rod to change the distance between the adjustment ring and the slider.

[0015] Furthermore, the adjusting ring is radially provided with a locking piece for limiting the position of the adjusting ring on the fixing rod.

[0016] Furthermore, the adjusting ring is threadedly connected to the fixing rod, and the position of the adjusting ring on the fixing rod is changed by rotating the adjusting ring.

[0017] Furthermore, an arc corner is provided at one opposite end of the two support plates, and the arc corner is arranged away from a side of the control component.

[0018] Furthermore, a lock buckle is provided at one end of the fixing rod away from the supporting plate, and the lock buckle is used to be connected to the force applying end.

[0019] Furthermore, the hinged part is an adjustable nylon hinge.

[0020] The present invention also includes a working method of a modular wind turbine blade trailing edge component bonding profile retaining device, which is applicable to the modular wind turbine blade trailing edge component bonding profile retaining device as described above, and the method includes:

[0021] Pull the force-applying end, and the two support plates are flipped at an angle and installed into the cavity area of ​​the trailing edge component;

[0022] After the support plate reaches the area corresponding to the position of the external restraining tooling, the force-applying end is released, and under the action of the elastic member, the two support plates are reset to the supporting state to support the cavity area of ​​the trailing edge component;

[0023] Repeat the above steps to sequentially arrange a plurality of the internal profile constraint modules at intervals along the axial direction of the trailing edge component;

[0024] Apply glue to the bonding area, and drive the trailing edge component to move chordwise to bond with the box body component;

[0025] After the adhesive is cured, the force-applying end is pulled, and the two support plates are folded at an angle to pull out the internal profile constraint module.

[0026] Furthermore, the force-applying ends of the adjacent internal profile constraint modules are connected in sequence, and the force-applying ends of the internal profile constraint modules at the end are pulled to pull out the multiple internal profile constraint modules synchronously.

[0027] Furthermore, the force-applying end of each of the internal profile constraint modules is led out separately, and the force-applying end of each of the internal profile constraint modules is pulled respectively to pull out the multiple internal profile constraint modules one by one.

[0028] The technical solution of the present invention can achieve the following technical effects:

[0029] By sequentially arranging the internal profile constraint modules along the axial direction of the trailing edge component at intervals, the internal profile constraint module comprises two aligned support plates and a control assembly for controlling the folding of the two support plates; when the force-applying end is not subjected to force, the elastic member drives the slider to reset, thereby driving the two support plates to reset, at which time the two support plates are in an aligned expanded state, and are used to support the bonding area, weak area and cavity area of ​​the trailing edge component; preventing the external force applied during the bonding process from deforming the trailing edge component, thereby ensuring the flatness and bonding quality of the bonding area; after the bonding is completed, the force-applying end is pulled to make the slider slide along the fixed rod, and the two support rods respectively drive the two support plates to rotate along the hinge to the side away from the control assembly, at which time the two support plates are in a folded state, which is convenient for pulling the internal profile constraint module out of the cavity area of ​​the trailing edge component, and is easy to remove and simple to operate, thereby improving production efficiency and avoiding time waste and reduced efficiency caused by the difficulty in removing in traditional methods.

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0047] like Figures 3 to 7As shown: a modular wind turbine blade trailing edge component bonding profile retaining device, comprising: internal profile constraint modules 1 sequentially arranged at intervals along the axial direction of the trailing edge component 01; the number of the internal profile constraint modules 1 is flexibly configured according to the on-site internal profile constraint modules 1, suitable for the bonding requirements of trailing edge components 01 of different lengths and shapes, and has strong adaptability;

[0048] The internal profile constraint module 1 is disposed in the cavity area 013 of the trailing edge component 01, and is used to support the bonding area 011, the weak area 012 and the cavity area 013 of the trailing edge component 01;

[0049] The internal profile constraint module 1 includes two aligned support plates 11 and a control assembly 12 for controlling the folding of the two support plates 11; a hinge is provided between the two support plates 11, and the control assembly 12 drives the two support plates 11 to rotate along the hinge, and the appearance of the two support plates 11 in the unfolded state is adapted to the cavity area 013 of the trailing edge component 01; thereby supporting the bonding area 011, the weak area 012 and the cavity area 013 of the trailing edge component 01, preventing the deformation of the trailing edge component 01 caused by external forces during the bonding process, and ensuring the flatness and bonding quality of the bonding area 011;

[0050] The control assembly 12 includes a fixed rod 121, an elastic member 122, a slider 123, a support rod 124 and a force-applying end 125. The fixed rod 121 is vertically arranged with the support plate 11 in the expanded state. The elastic member 122 and the slider 123 are arranged on the side of the fixed rod 121 away from the support plate 11. The slider 123 slides along the fixed rod 121, and the elastic member 122 is used for resetting the slider 123.

[0051] Two support rods 124 are symmetrically arranged along the length direction of the fixed rod 121, one end of the support rod 124 is hinged to the support plate 11, and the other end is hinged to the slider 123;

[0052] The force-applying end 125 is arranged on the side of the fixed rod 121 away from the support plate 11. The force-applying end 125 is subjected to force to cause the slider 123 to slide along the fixed rod 121, and the two support rods 124 respectively drive the two support plates 11 to rotate along the hinge to the side away from the control component 12; the force on the force-applying end 125 is cancelled, and the elastic member 122 drives the slider 123 to reset, thereby driving the two support plates 11 to reset, which simplifies the operation steps, helps to optimize the production process, shorten the production cycle, and improve the overall production efficiency.

[0053] The internal profile constraint module 1 is sequentially arranged along the axial interval of the trailing edge component 01, and the internal profile constraint module 1 includes two aligned support plates 11 and a control component 12 for controlling the folding of the two support plates 11; when the force-applying end 125 is not subjected to force, the elastic member 122 drives the slider 123 to reset, thereby driving the two support plates 11 to reset, such as Figure 3 , Figure 4 As shown, at this time, the two support plates 11 are in an aligned unfolded state, and are used to support the bonding area 011, the weak area 012 and the cavity area 013 of the rear edge component 01; prevent the external force applied during the bonding process from deforming the rear edge component 01, thereby ensuring the flatness and bonding quality of the bonding area 011; after the bonding is completed, pull the force-applying end 125 to make the slider 123 slide along the fixed rod 121, and the two support rods 124 respectively drive the two support plates 11 to rotate along the hinge to the side away from the control component 12, as shown in FIG. Figure 7 As shown, the two support plates 11 are in a folded state, which makes it easy to pull the internal surface constraint module 1 out of the cavity area 013 of the trailing edge component 01. The removal is convenient and the operation is simple, thereby improving production efficiency and avoiding time waste and reduced efficiency caused by the difficulty in removal in traditional methods.

[0054] After being pulled out, the internal profile constraint module 1 can be reused, which reduces material waste and cost expenditure in the production process and helps to improve economic benefits.

[0055] As a preferred embodiment of the above embodiment, the position of the internal profile constraint module 1 corresponds to the position of the external constraint tooling, so that the internal and external force points are consistent, ensuring that the rear edge component 01 is subjected to uniform force during the bonding process, effectively preventing local deformation, thereby ensuring the flatness and bonding quality of the bonding area 011, and improving the bonding strength and durability.

[0056] In this embodiment, a hinge seat 129 is provided on the support plate 11, and a rotating shaft 130 is provided between the hinge seat 129 and the support rod 124. The support rod 124 rotates along the rotating shaft 130, thereby causing the slider 123 to move along a fixed straight line, which is converted into a folding movement of the two support plates 11 along the hinge through the support rod 124 being hinged with the sliders 123 and the hinge seat 129 on both sides; in addition, the hinge seat 129 and the rotating shaft 130 facilitate separation of the control component 12 and the support plate 11, and the control component 12 can be used on support plates 11 of other shapes, which can reduce production costs and improve production efficiency.

[0057] Among them, the force-applying end 125 is a rope or a rod, that is, a soft nylon rope or a relatively hard rod can be used as the force-applying end 125, both of which are within the protection scope of the present application. Specifically, a nylon rope is used in this embodiment. The nylon rope has good flexibility and bendability, can better adapt to complex shapes and curved surfaces, and helps to achieve more uniform force transmission during the bonding process.

[0058] As a preferred embodiment of the above, Figure 5As shown, it also includes an adjusting ring 127, which is arranged on the fixing rod 121. The adjusting ring 127 is arranged at one end of the elastic member 122 away from the slider 123. The adjusting ring 127 moves on the fixing rod 121 and is fixed at any position of the fixing rod 121 to change the distance between the adjusting ring 127 and the slider 123; thereby changing the compression amount of the elastic member 122, thereby adjusting the elastic force when the support plate 11 is reset, so that the elastic force can be accurately adjusted according to actual needs, ensuring that the support plate 11 can be accurately reset, and improving the operating accuracy of the device.

[0059] An implementation of the adjusting ring 127 is as follows: the adjusting ring 127 is radially provided with a locking piece for limiting the position of the adjusting ring 127 on the fixing rod 121, so that the distance between the adjusting ring 127 and the slider 123 can be accurately controlled during the adjustment process, thereby accurately adjusting the compression amount of the elastic member 122, thereby improving the accuracy of the adjustment and the controllability of the operation.

[0060] Another implementation of the adjustment ring 127 is: the adjustment ring 127 and the fixed rod 121 are threadedly connected, and the position of the adjustment ring 127 on the fixed rod 121 is changed by rotating the adjustment ring 127, so as to accurately adjust the compression amount of the elastic member 122, thereby improving the accuracy of adjustment and the controllability of operation, and the operation is simple and quick.

[0061] In this embodiment, if Figure 6 As shown, an arc angle 111 is provided at one opposite end of the two support plates 11, and the arc angle 111 is arranged away from the side of the control component 12. When the force-applying end 125 is subjected to force, the two support plates 11 are in a folded state along the hinge. On the one hand, the arc angles 111 of the two support plates 11 are tangent to each other and support each other to form a uniform support surface, which can more evenly bear the force applied to the support plates 11, reduce local stress concentration, and improve the stability and bearing capacity of the device; on the other hand, it can ensure that the two support plates 11 maintain good alignment in the folded state, prevent deformation caused by misalignment or mutual extrusion of the support plates 11, and ensure the stability and accuracy of the device during use; in addition, the design of the arc angle 111 enables the support plates 11 to better cooperate with each other in the folded state, thereby improving the overall stability and reliability of the device.

[0062] Among them, reference Figure 5 A lock buckle 128 is provided at one end of the fixing rod 121 away from the supporting plate 11, and the lock buckle 128 is used to connect with the force-applying end 125. On the one hand, the design of the lock buckle 128 makes the connection and disconnection operations simpler and faster, which can effectively save the operation time of the device and improve the operation efficiency; on the other hand, the lock buckle 128 can ensure that the fixing rod 121 is firmly connected to the force-applying end 125, preventing loosening or falling off due to loose connection during use, thereby improving the safety and reliability of the device.

[0063] As a preferred embodiment of the above, refer to Figure 3 The hinge is an adjustable nylon hinge 126; specifically, the adjustable nylon hinge 126 controls its folding position. One implementation method is to set an adjusting screw or nut in the hinge, and the opening angle or opening force of the hinge can be changed by rotating the adjusting screw or nut, thereby controlling the position state of the hinge when folding; that is, the folding position state can be controlled, so that the hinge has a certain degree of adjustability during use, and can be adjusted according to actual needs, thereby ensuring the smoothness and controllability of the folding process and avoiding adverse conditions caused by sudden loosening or clamping.

[0064] The present invention also includes a working method of a modular wind turbine blade trailing edge component bonding profile retaining device, which is applicable to the modular wind turbine blade trailing edge component bonding profile retaining device as described above. Figures 8 to 12 As shown, the method includes:

[0065] S10: Pull the force-applying end 125, and the two support plates 11 are flipped at an angle and installed into the cavity area 013 of the trailing edge component 01; in this step, the two support plates 11 are folded to reduce the space, and are installed into the cavity area 013 of the trailing edge component 01 from the opening of the trailing edge component 01;

[0066] S20: After the support plate 11 reaches the area corresponding to the external constraint tooling position, the force-applying end 125 is released, and under the action of the elastic member 122, the two support plates 11 are reset to the supporting state to support the cavity area 013 of the trailing edge component 01; this step is to unfold the support plate 11 in the area corresponding to the external constraint tooling position, so that the internal and external force points are consistent, and ensure that the trailing edge component 01 is uniformly stressed during the bonding process, effectively preventing local deformation, thereby ensuring the flatness and bonding quality of the bonding area 011, and improving the bonding strength and durability;

[0067] S30: Repeat the above steps S10 to S20. Figure 8 As shown, a plurality of internal profile constraint modules 1 are sequentially arranged at intervals along the axial direction of the trailing edge component 01; in this step, by arranging a plurality of internal profile constraint modules 1 at intervals along the axial direction of the trailing edge component 01, a large area of ​​bonding support can be completed quickly and efficiently, thereby improving production efficiency. The number of the internal profile constraint modules 1 is determined according to the length of the trailing edge component 01 on site;

[0068] S40: Fig. 9 , Fig.10 As shown, glue is applied to the bonding area 011, and the trailing edge component 01 is driven to move chordwise to bond with the box component 02; this step applies external force to the bonding area 011 to ensure the bonding quality and control the thickness of the glue layer, so as to ensure that the bonding area 011 has no quality defects such as hollowing and lack of glue;

[0069] S50: Fig.11 , Fig.12 As shown, after the adhesive is cured, the force-applying end 125 is pulled, and the two support plates 11 are folded at an angle to pull out the internal profile constraint module 1. The device can be dismantled, and the removal operation is simple and convenient.

[0070] After the adhesive is cured, the two support plates 11 can be folded at an angle by simply pulling the force-applying end 125, thereby pulling out the internal profile constraint module 1. The operation is simple and easy to execute, reducing the complex operation and time consumption during the removal process; the simple removal process can significantly improve production efficiency and reduce the time and labor required to remove the internal profile constraint module 1; due to the simple pulling operation, the potential damage to the bonding area and the trailing edge component 01 is reduced, ensuring the bonding quality and the integrity of the assembly; the removal process is simple, and the internal profile constraint module 1 can be quickly and easily taken out and used in the next production cycle, improving the reuse rate of the device and saving resources and costs.

[0071] As a preferred embodiment of the above, as an implementation method of dismantling the device in step S50, refer to Fig.11 The force-applying ends 125 of adjacent internal profile constraint modules 1 are connected in sequence, and the force-applying ends 125 of the end internal profile constraint modules 1 are pulled to pull out multiple internal profile constraint modules 1 synchronously; on the one hand, the operator only needs one operation to pull out multiple constraint modules synchronously, which significantly improves the efficiency of the dismantling process and reduces the dismantling time and labor intensity; on the other hand, synchronously pulling out multiple internal profile constraint modules 1 reduces the process of dismantling each module separately, saves time and labor costs, and improves the work efficiency of the overall production line; in addition, synchronous pulling out can ensure that each module is subjected to the same pulling force at the same time point, ensuring the uniformity of force on each module during the dismantling process, and avoiding deformation or damage of the bonding area 011 caused by uneven force during separate dismantling.

[0072] In this embodiment, as another implementation method for dismantling the device in step S50, the force-applying end 125 of each internal profile constraint module 1 is led out separately, and the force-applying end 125 of each internal profile constraint module 1 is pulled separately to pull out multiple internal profile constraint modules 1 one by one; dismantling the internal profile constraint modules 1 one by one can gradually monitor the status of each module, promptly discover and solve problems that may arise during the dismantling process, and reduce operational risks.

[0073] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
