Wind power generation refers to converting the kinetic energy of wind into electrical energy. Utilizing wind power is very environmentally friendly and can generate a huge amount of electricity. As one of the clean energy sources with the best development prospects, wind power generation is widely promoted and applied. Wind power generation technology cannot function without the support of wind turbine units. Wind turbine blades are crucial components of wind turbine units used to capture wind energy; their manufacturing quality determines their operational performance, and consequently, the power generation of the wind turbine unit.

[0003] In the production of wind turbine blades, the web, as the main supporting component, plays a crucial role in the overall quality of the blade. The web bonding area is a core area of ​​the wind turbine blade, which is difficult and costly to repair. Problems there can lead to a decline in blade performance, essentially resulting in the blade being scrapped. Therefore, the quality of web assembly technology is extremely important for mitigating quality risks in wind turbine blades.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: the existing wind turbine blade web assembly lacks positioning fixtures, and due to the different bending angles of the blade root and web of different specifications of blades, the web is prone to tilting inward when bonding the web to the blade root, and there are problems of low precision and low work efficiency in web assembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning device for the web and root of a wind turbine blade. This solves the problems of the lack of positioning fixtures in the existing wind turbine blade web assembly, and the fact that due to the different bending angles of the root and web of blades of different specifications, the web is prone to tilting inward during the bonding work between the web and the root. Furthermore, the web assembly has low precision and low work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for the web and root of a wind turbine blade, comprising a base, the interior of which is provided with a square groove, a pair of limiting rods connected between the inner walls of the square groove, a bidirectional lead screw rotatably connected between the inner walls of the square groove, a third knob connected to one end of the bidirectional lead screw outside the base, a pair of moving blocks threadedly connected to the bidirectional lead screw, both of the moving blocks being slidably mounted on the pair of limiting rods, a pair of vertical plates provided at the upper ends of each pair of moving blocks, and a height adjustment mechanism provided within each pair of vertical plates. The height adjustment mechanism includes a first sliding groove formed in one side wall of the vertical plate, a first sliding rod connected between the upper and lower walls of the first sliding groove, a first threaded rod rotatably connected between the upper and lower walls of the first sliding groove, a first knob connected to the upper end of the first threaded rod outside the vertical plate, a first slider threadedly connected to the first threaded rod, the first slider being slidably mounted on the first sliding rod, and a pair of clamping components mounted on the side wall of the first slider.

[0007] Preferably, the clamping assembly includes a connecting plate mounted on the side wall of the first slider, a cylinder inside the connecting plate, a second threaded rod rotatably connected inside the cylinder, a second knob connected to one end of the second threaded rod, a sleeve rod movably inserted inside the cylinder, the sleeve rod being threadedly connected to the second threaded rod, a pair of second sliding grooves on the inner wall of the cylinder, a pair of second sliders on the side wall of the sleeve rod, the pair of second sliders being slidably mounted in the pair of second sliding grooves respectively, and a clamping plate hinged to the other end of the sleeve rod.

[0008] Preferably, the pair of clamping components connected to the sidewall of the first slider are arranged in a mirror-symmetrical manner.

[0009] Preferably, the walls of the clamping plates are provided with an anti-slip layer.

[0010] Preferably, each pair of the limiting rods is provided with a pair of limiting plates. Beneficial effects

[0011] This invention provides a positioning device for the web and root of a wind turbine blade. The device features a structure for fixing webs and blade roots with different curvatures. The web is placed between a pair of vertical plates, with the installation axis as a reference. Adjusting the first and second knobs moves each pair of clamping plates relative to each other, allowing them to adhere to the curvature of the web, thus fixing it in place. The blade root installation process is similar; manually turning the third knob brings the blade root into contact with the web for bonding. This device allows for multi-angle adjustment to fix webs and blade roots with different curvatures, aiding in bonding and demonstrating strong practicality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a positioning device for the web and root of a wind turbine blade, including a base 1. The base 1 has a square groove 2 inside. A pair of limiting rods 4 are connected between the inner walls of the square groove 2. A bidirectional lead screw 5 is rotatably connected between the inner walls of the square groove 2. One end of the bidirectional lead screw 5, located outside the base 1, is connected to a third knob 21. A pair of moving blocks 3 are threaded onto the bidirectional lead screw 5. Both moving blocks 3 are slidably mounted on the pair of limiting rods 4. A pair of vertical plates 6 are provided at the upper end of each pair of moving blocks 3. Each of the vertical plates 6 is provided with a height adjustment mechanism. The height adjustment mechanism includes a first sliding groove 7 formed in one side wall of the vertical plate 6. A first sliding rod 8 is connected between the upper and lower walls of the first sliding groove 7. A first threaded rod 9 is rotatably connected between the upper and lower walls of the first sliding groove 7. A first knob 11 is connected to the upper end of the first threaded rod 9 and located outside the vertical plate 6. A first slider 10 is threadedly connected to the first threaded rod 9. The first slider 10 is slidably mounted on the first sliding rod 8. A pair of clamping components are installed on the side wall of the first slider 10.

[0018] In this embodiment, the clamping assembly includes a connecting plate 12 installed on the side wall of the first slider 10. A cylinder 14 is provided inside the connecting plate 12. A second threaded rod 15 is rotatably connected inside the cylinder 14. One end of the second threaded rod 15 is connected to a second knob 13. A sleeve rod 18 is movably inserted inside the cylinder 14. The sleeve rod 18 is threadedly connected to the second threaded rod 15. A pair of second sliding grooves 17 are provided on the inner wall of the cylinder 14. A pair of second sliders 16 are provided on the side wall of the sleeve rod 18. The pair of second sliders 16 are slidably installed in the pair of second sliding grooves 17 respectively. A clamping plate 19 is hinged to the other end of the sleeve rod 18.

[0019] In this embodiment, the pair of clamping components connected to the side wall of the first slider 10 are arranged in a mirror-symmetrical manner.

[0020] In this embodiment, the clamping plate 19 is further configured to have an anti-slip layer on its wall surface.

[0021] In this embodiment, each pair of limiting rods 4 is provided with a pair of limiting plates 20.

[0022] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0023] Example: The unassembled blade root and web portions can be fixedly mounted on the moving block 3. The specific installation process is as follows: the web is placed between a pair of vertical plates 6, with the installation axis as the reference. The first knob 11 can be turned to rotate the first threaded rod 9. The rotation of the first threaded rod 9 causes the first slider 10 to slide on the first slide rod 8. Then, the second knob 13 is turned to rotate the second threaded rod 15. The rotation of the second threaded rod 15 causes the sleeve rod 18 to extend and retract. The second slider 16 always slides on the second slide groove 17, which has a limiting effect. The extension and retraction of the sleeve rod 18 causes the clamping plate 19 to move up and down. The clamping plate 19 rotates and the anti-slip layer on the wall contacts the web. By moving the two pairs of clamping plates 19 relative to each other and pressing against the curvature of the web, the web is fixed. The installation process of the blade root is the same. The third knob 21 is turned manually to rotate the bidirectional screw 5. The rotation of the bidirectional screw 5 causes a pair of moving blocks 3 to move relative to each other along the limiting rod 4. The blade root contacts the web portion for bonding.
