On the one hand, the blades of high-power wind turbine generators will become longer and longer. The wind turbine blade mainly consists of a shell and a web. The shell is composed of two half-shells, namely the windward shell and the leeward shell. The hollow space between the two half-shells is supported by the web in the extending direction of the blade.

[0003] The web is an important component of the wind turbine blade. After the web is demolded from the mold by a lifting beam, it needs to be stored. However, the web is a special-shaped and curved sheet, and the angles of the storage support points required for each section of the web are different. The bottom of the existing web storage device is fixedly arranged and cannot be flexibly adjusted to adapt to webs of different shapes and sizes, resulting in the bottom of the web not fitting the bottom of the storage device. It may slide or collapse due to gravity or other external forces, causing damage to the web or personnel and increasing potential safety hazards.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] As Figures 1 to 6 shown: A modular blade web storage device includes a plurality of support modules 1 arranged in sequence along the length direction of the web 01 (refer to Figure 1 ).

[0033] The support module 1 includes a base 11 and a moving frame 12. An elevating assembly 15 is provided between the moving frame 12 and the base 11 for driving the moving frame 12 to approach or move away from the base 11.

[0034] The moving frame 12 includes a base 121, vertical rods 122, and inclined rods 123. A plurality of vertical rods 122 are perpendicularly arranged with respect to the base 121, and both ends of the inclined rod 123 are respectively arranged on the base 121 and the vertical rod 122; a stable triangular structure is formed between each inclined rod 123, vertical rod 122, and base 121 to increase the stability of the moving frame 12.

[0035] A moving seat 14 and a telescopic assembly 13 are provided between adjacent two vertical rods 122. A first rotating shaft 144 is provided between one end of the moving seat 14 and the vertical rod 122, and the other end is hinged to the output end of the telescopic assembly 13. The telescopic assembly 13 makes a lifting movement to drive the moving seat 14 to rotate along the first rotating shaft 144, thereby driving the angle change of the top surface of the moving seat 14.

[0036] As shown in Figure 2 , 3 the position of the moving frame 12 is adjusted by the lifting component 15, so that the moving seat 14 matches the height change at different positions of the web 01 in the height direction. Moreover, by setting the telescopic component 13 in each support module 1, the angle of the top surface of the moving seat 14 can be flexibly adjusted to adapt to the support angles required by different parts of the web 01, so as to precisely match the shape change of the web 01. This precise matching not only improves the storage stability of the web 01, but also reduces the risk of damage caused by improper support, ensures that there is a tight fit between the bottom of the web 01 and the storage device, avoids damage and instability caused by angle mismatch, and improves the storage safety and protection effect of the web 01.

[0037] Since there is a lifting component 15 between the moving frame 12 and the base 11, the moving frame 12 can be lifted, which is convenient for adjusting and supporting the height of the web 01 corresponding to the abnormally curved sheet at different positions. Generally, for the abnormally curved sheet with a narrowing shape from the end to the tail of the web 01, the moving seat 14 on the support module 1 from the end to the tail needs to be gradually raised. By using the lifting component 15 to lift the entire moving frame 12 as a whole, the moving seat 14 can be lifted to different heights corresponding to different positions of the web 01, so as to precisely match the shape change of the web 01. This precise matching not only improves the storage stability of the web 01, but also reduces the risk of damage caused by improper support.

[0038] The support module 1 has a simple structure, which minimizes the size of the storage tooling and saves costs; the automatic control of the lifting component 15 and the telescopic component 13 enables the operator to easily adjust the position and angle of the support point without manually moving or adjusting the web 01, which not only simplifies the operation process, but also reduces the labor intensity and improves the work efficiency.

[0039] The modular design enables the storage device to be freely combined and increased or decreased according to actual needs, so as to flexibly adapt to the webs 01 with different sizes and shapes. This not only improves the utilization rate of the storage space, but also enables the storage device to be applicable to a wider range of production scenarios of wind turbine blades.

[0040] As shown in Figure 5As shown in the figure, as a specific implementation of the moving seat 14, the moving seat 14 includes a first template 141 and a second template 142 symmetrically arranged on both sides of the vertical rod 122 in the thickness direction. The tops of the first template 141 and the second template 142 are provided with inclined surface segments 141a. Specifically, during use, the web 01 is placed on the inclined surface segments 141a. By adjusting the sizes of the inclined surfaces on each moving seat 14 to fit different positions of the web 01, the inclined surface segments 141a can gradually guide the web 01 and enable it to be stably placed on the support points, reducing the stress and deformation risks caused by shape mismatch. However, there are only inclined surface segments 141a on the first template 141 and the second template 142, and the web 01 is likely to slide along the inclined surface segments 141a to one side and contact the vertical rod 122, which is likely to damage the web 01. Therefore, we have made the following improvements;

[0041] As Figure 6 As shown in the figure, as another specific implementation of the moving seat 14, the moving seat 14 includes a first template 141 and a second template 142 symmetrically arranged on both sides of the vertical rod 122 in the thickness direction. The tops of the first template 141 and the second template 142 are provided with inclined surface segments 141a in the middle and straight surface segments 141b on both sides. Specifically, on the one hand, the added straight surface segments 141b on both sides provide a stable support boundary for the web 01. When the web 01 is placed on the moving seat 14, the straight surface segments 141b can prevent the web 01 from sliding excessively along the inclined surface segments 141a, ensuring that the web 01 always remains in the correct position and avoiding direct contact and potential damage between the web 01 and the vertical rod 122; on the other hand, the added straight surface segments 141b on both sides provide a stable support boundary for the web 01; when the web 01 is placed on the moving seat 14, the straight surface segments 141b can prevent the web 01 from sliding excessively along the inclined surface segments 141a, ensuring that the web 01 always remains in the correct position and avoiding direct contact and potential damage between the web 01 and the vertical rod 122.

[0042] As a preference of the above embodiment, a conforming thin plate 143 made of soft rubber is laid on the tops of the first template 141 and the second template 142. Specifically, on the one hand, the conforming thin plate 143 made of soft rubber has excellent buffering and shock absorption properties, which can effectively reduce the direct impact and friction between the web 01 and the moving seat 14, avoiding scratches on the surface of the web 01 caused by scraping and collision during storage and removal, and protecting the integrity and aesthetics of the web 01; on the other hand, the soft rubber material has good anti-slip properties, which can increase the friction between the web 01 and the conforming thin plate 143, preventing the web 01 from sliding due to vibration or external force during storage, helping to keep the web 01 in the correct position in the storage device, and improving the safety and reliability of storage.

[0043] In this embodiment, a fixing plate 131 is provided between two adjacent vertical rods 122 and at the bottom of the moving seat 14. The fixing plate 131 is used to fix the telescopic assembly 13. Specifically, the setting of the fixing plate 131 strengthens the connection between the telescopic assembly 13 and the vertical rod 122, making the structure of the entire storage device more stable, and helping to prevent shaking and tilting caused by vibration or external forces during the storage and movement of the web 01, improving the overall stability and safety of the storage device.

[0044] Among them, a second rotating shaft 145 is provided at one end of the first template 141 and the second template 142 away from the first rotating shaft 144. The second rotating shaft 145 and the telescopic assembly 13 are connected by a spherical plain bearing 132. Specifically, when the telescopic assembly 13 drives the moving seat 14 to rotate along the first rotating shaft 144, thereby adjusting the angle between the moving seat 14 and the bottom of the web 01, the design of the spherical plain bearing 132 allows a certain degree of swing freedom between the second rotating shaft 145 and the telescopic assembly 13. This flexibility enables the moving seat 14 to better adapt to adjustments at different angles and positions during the lifting process, and can reduce the risk of jamming or damage caused by rigid connection.

[0045] As a preference of the above embodiment, guiding openings 122a are provided on the opposite sides of the tops of two adjacent vertical rods 122. Specifically, the guiding openings 122a provide precise guidance for the hoisting process of the web 01. When the moving seat 14 or the web 01 moves between the vertical rods 122, the guiding openings 122a can ensure that they move along a predetermined trajectory, reducing errors caused by deviation or shaking, and improving the positioning accuracy of the storage device.

[0046] In this embodiment, the base 11 is provided with a plurality of guide sleeves 111, and the base 121 is provided with a plurality of guide posts 121a. A part of the guide posts 121a is arranged in the guide sleeves 111 for guiding the lifting of the moving frame 12. On the one hand, the combination of the guide sleeves 111 and the guide posts 121a provides stable guidance for the lifting of the moving frame 12, ensuring that the moving frame 12 moves along a predetermined vertical direction during the lifting process, reducing instability caused by deviation or shaking, and improving the safety of the entire storage device; on the other hand, the contact surface between the guide sleeves 111 and the guide posts 121a is usually designed to be relatively smooth to reduce friction, helping to reduce the resistance and noise during the lifting of the moving frame 12, and at the same time reducing wear caused by friction, extending the service life of the equipment.

[0047] Among them, the telescopic component 13 is one of a worm gear lift, an oil cylinder, and a cylinder, providing multiple options for the telescopic component 13, enabling the storage device to be flexibly configured according to specific application scenarios and requirements. In this embodiment, the telescopic component 13 can be a worm gear lift, and the telescopic component 13 can be manually driven or automatically driven. For example, a handwheel 133 can be provided outside the worm gear lift, or a motor can be provided in the worm gear lift. Rotating the handwheel 133 or the motor to control the slope of the top surface of the moving seat 14 is within the protection scope of this application and can be selected according to the actual on-site requirements.

[0048] As a preference of the above embodiment, floor plates 112 are provided at at least four corners of the bottom of the base 11. Each floor plate 112 at least partially extends out of the base 121, and through holes 112a for fixed installation are provided on the base 11. On the one hand, the design of the floor plates 112 increases the contact area between the base 11 and the ground, thereby improving the stability of the entire storage device. The floor plates 112 can provide better support and anti-slip effects, ensuring that the storage device will not shake or tip over during use; on the other hand, the through holes 112a provided on the base 11 facilitate fixed installation. The storage device can be firmly installed at a designated position through fasteners such as bolts and nuts, which not only enhances the stability of the storage device but also helps prevent displacement or tipping over caused by accidental collision or external force.
