DETAILED DESCRIPTION​

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a wind turbine generator anchor plate: it includes an anchor plate body 1, which is a circular plate structure. A central through hole 2 is provided at the center of the anchor plate body 1. Multiple anchor bolt mounting holes 3 are evenly distributed along the edge of the anchor plate body 1. A reinforcing boss 4 is provided around each anchor bolt mounting hole 3. The reinforcing boss 4 is integrally formed with the anchor plate body 1. The upper and lower surfaces of the anchor plate body 1 are provided with crisscrossing reinforcing ribs 5. The reinforcing ribs 5 are integrally formed with the anchor plate body 1. A reinforcing part 6 is fixedly installed on the outer ring of the anchor plate body 1. Several groups of reinforcing parts 6 are evenly distributed on the outer ring of the anchor plate body 1. Each group of reinforcing parts 6 is provided with a sliding groove 7. A movable pressure block 8 is installed in the sliding groove 7. The movable pressure block 8 is slidably connected in the sliding groove 7. A fastening bolt 9 is installed on the movable pressure block 8. A lifting ring 10 is detachably installed on the outer ring of the anchor plate body 1.

[0022] Furthermore, the fastening bolt 9 is threadedly connected to the movable pressure block 8, and one end of the fastening bolt 9 is rotatably connected to the side wall of the slide groove 7.

[0023] Specifically, a pressure plate 11 is installed on the movable pressure block 8, and an anti-slip pad 12 is fixedly installed on one side of the pressure plate 11.

[0024] In this embodiment, when the fastening bolt 9 rotates, it will drive the movable pressure block 8 to move in the slide groove 7, so that the pressure plate 11 can contact the outer wall of the wind turbine tower, thereby improving the stability of the installation.

[0025] Furthermore, on the lower surface of the anchor plate body 1, with the central through hole 2 as the center, an annular positioning boss 13 is also provided, and the height of the positioning boss 13 is higher than the height of the reinforcing rib 5.

[0026] In this embodiment, the positioning boss 13 can accurately position the anchor plate body 1 during the installation process, ensuring that the connection position between the anchor plate body 1 and the foundation is accurate, thereby improving the installation accuracy and efficiency and reducing the installation difficulty.

[0027] Further, the height of the reinforcing boss 4 is 5-10mm, and the diameter of the reinforcing boss 4 is 10-20mm larger than the diameter of the anchor mounting hole 3, which can effectively enhance the strength of the connection between the anchor plate body 1 and the anchor.

[0028] In this embodiment, the reinforcing boss 4 can increase the contact area between the anchor and the anchor plate body 1, thereby improving the stability of the connection and reducing the possibility of loosening or uneven stress under long-term complex load.

[0029] Further, the outer ring of the anchor plate body 1 is provided with a threaded hole 14, and one end of the lifting ring 10 is installed in the threaded hole 14 by threaded connection.

[0030] Further, the height of the positioning boss 13 is 10-15mm, and the outer diameter of the positioning boss 13 is 50-100mm larger than the diameter of the center through hole 2, which facilitates quick and accurate positioning of the anchor plate during installation, improving installation efficiency and accuracy.

[0031] Further, the height of the reinforcing rib 5 is 3-8mm, and the width is 5-15mm, and the transversely staggered reinforcing ribs 5 can significantly improve the overall strength and deformation resistance of the anchor plate body 1.

[0032] Working principle: In use, the tower of the wind turbine generator is fixedly connected with the anchor plate body 1 through the anchor mounting hole 3. The reinforcing boss 4 can increase the contact area between the anchor and the anchor plate body 1, thereby improving the stability of the connection and reducing the possibility of loosening or uneven stress under long-term complex load. At the same time, the arrangement of the reinforcing rib 5 can further improve the overall strength and deformation resistance of the anchor plate body 1, so that it can better withstand various loads during operation of the wind turbine generator.

[0033] The positioning boss 13 can accurately position the anchor plate body 1 during installation, ensuring that the connection position of the anchor plate body 1 and the foundation is accurate, thereby improving the installation accuracy and efficiency and reducing the installation difficulty. The cooperation of the movable pressing block 8 and the fastening bolt 9 can further fix the tower of the wind turbine generator, enhancing the overall connection stability.

[0034] The arrangement of the lifting ring 10 facilitates hoisting of the anchor plate body 1 during transportation and installation, improving the operation convenience. The arrangement of the non-slip pad 12 can increase the friction between the pressing plate 11 and the contact surface, preventing sliding during tightening and further ensuring the stability of the connection.
