Description

Technical Field

[0001] This utility model relates to the field of anchor plate structure technology, specifically a high-strength wind turbine anchor plate structure. Background Technology

[0002] With the rapid development of clean energy, wind power generation, as an important renewable energy source, has been widely applied. The stable operation of wind turbines is crucial for power generation efficiency and safety, and the anchor plate structure, as a key component connecting the wind turbine foundation and the tower, directly affects the overall stability of the wind turbine.

[0003] Currently, existing wind turbine anchor plate structures have some shortcomings when facing high-intensity wind loads. On the one hand, the connection strength between the anchor plate and the foundation concrete is limited, and under long-term strong wind loads, the anchor plate is prone to detaching from the concrete, reducing the stability of the wind turbine. On the other hand, the existing anchor plate structure is not uniform in stress distribution, with some areas bearing greater stress, which can easily lead to localized damage to the anchor plate, shortening its service life, increasing maintenance costs, and posing safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a solution to the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength wind turbine anchor plate structure, comprising a circular anchor plate body, wherein multiple bolt holes for connecting to the tower are evenly distributed on the anchor plate body, a central hole is provided at the center of the anchor plate body, a reinforcing rib network is provided on the upper surface of the anchor plate body, multiple anti-slip protrusions are provided on the lower surface of the anchor plate body, an annular outer reinforcing flange is also provided at the edge of the anchor plate body, and an annular inner reinforcing flange is also provided at the edge of the central hole, wherein the height of the outer and inner reinforcing flanges is higher than the height of the anti-slip protrusions, and a reinforcing structure is provided on the outer side of the anchor plate body, the reinforcing structure comprising an annular reinforcing plate, a lower reinforcing plate and an upper reinforcing plate, wherein the lower reinforcing plate and the upper reinforcing plate are respectively located on both sides of the annular reinforcing plate.

[0006] Preferably, an annular reinforcing groove is provided on the outer side of the anchor plate body, and reinforcing plates are uniformly fixedly installed in the annular reinforcing groove with the center of the anchor plate body as the center. The outer side of the reinforcing plate is fixedly connected to the lower reinforcing plate and the upper reinforcing plate respectively.

[0007] Preferably, the inner wall of the bolt hole is provided with an internal thread, and a circular reinforcing pad is provided around the bolt hole, the reinforcing pad being welded and fixed to the anchor plate body.

[0008] Preferably, the reinforcing rib network is composed of transverse reinforcing ribs and longitudinal reinforcing ribs that are perpendicularly and intersecting each other, and both the transverse and longitudinal reinforcing ribs are integrally formed with the anchor plate body.

[0009] Preferably, the anti-slip protrusions are triangular prisms and are evenly distributed along the radial direction of the anchor plate body.

[0010] Preferably, the cross-sections of the transverse and longitudinal reinforcing ribs are trapezoidal, and the width of the upper base of the trapezoid is smaller than the width of the lower base.

[0011] Preferably, the annular reinforcing plate has a plurality of evenly distributed connecting holes on its sidewall, and anchoring steel bars are inserted through the connecting holes. One end of the anchoring steel bar is fixed to the annular reinforcing plate by welding, and the other end extends into the foundation concrete.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The outer and inner reinforcing flanges of this utility model not only enhance the strength of the anchor plate's edge and central area, but also optimize the stress distribution of the anchor plate, reduce local stress concentration, and extend the service life of the anchor plate.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a high-strength wind turbine anchor plate structure technical solution: it includes a circular anchor plate body 1, on which multiple bolt holes 2 for connecting to the tower are evenly opened, a central hole 3 is provided at the center of the anchor plate body 1, a reinforcing rib network 4 is provided on the upper surface of the anchor plate body 1, multiple anti-slip protrusions 5 are provided on the lower surface of the anchor plate body 1, an annular outer reinforcing flange 6 is also provided at the edge of the anchor plate body 1, and an annular inner reinforcing flange 7 is also provided at the edge of the central hole 3. The height of the outer reinforcing flange 6 and the inner reinforcing flange 7 is higher than the height of the anti-slip protrusions 5. A ring of reinforcing structure 8 is provided on the outer side of the anchor plate body 1. The reinforcing structure 8 includes an annular reinforcing plate 9, a lower reinforcing plate 10 and an upper reinforcing plate 11, with the lower reinforcing plate 10 and the upper reinforcing plate 11 located on both sides of the annular reinforcing plate 9.

[0021] Furthermore, an annular reinforcing groove 12 is provided on the outer side of the anchor plate body 1, and reinforcing plates 13 are uniformly fixedly installed in the annular reinforcing groove 12 with the center of the anchor plate body 1 as the center. The outer side of the reinforcing plates 13 is fixedly connected to the lower reinforcing plate 10 and the upper reinforcing plate 11 respectively.

[0022] Furthermore, the inner wall of the bolt hole 2 is provided with an internal thread, and a circular reinforcing pad 14 is provided around the bolt hole 2. The reinforcing pad 14 is welded and fixed to the anchor plate body 1. By providing the reinforcing pad 14, the stress-bearing area during bolt connection can be increased, the stress concentration around the bolt hole can be reduced, and the reliability of the connection between the anchor plate and the tower can be further improved.

[0023] Furthermore, the reinforcing rib network 4 is composed of transverse reinforcing ribs 15 and longitudinal reinforcing ribs 16 that are perpendicularly and intersecting each other, and both the transverse reinforcing ribs 15 and the longitudinal reinforcing ribs 16 are integrally formed with the anchor plate body 1.

[0024] Furthermore, the anti-slip protrusions 5 are triangular prisms and are evenly distributed along the radial direction of the anchor plate body 1, which enables the anti-slip protrusions to be better embedded in the concrete, enhances the friction and interlocking force between the anchor plate and the concrete, and effectively prevents the anchor plate from sliding in the concrete.

[0025] Furthermore, the cross sections of the transverse reinforcing rib 15 and the longitudinal reinforcing rib 16 are both trapezoidal, and the width of the upper base of the trapezoid is smaller than the width of the lower base. The trapezoidal cross section design enables the reinforcing rib to better distribute the force to the anchor plate body when it is under stress, thereby improving the load-bearing capacity and stability of the reinforcing rib.

[0026] Furthermore, the annular reinforcing plate 9 has a plurality of evenly distributed connecting holes 17 on its sidewall. Anchor steel bars 18 are inserted through the connecting holes 17. One end of the anchor steel bar 18 is fixed to the annular reinforcing plate 9 by welding, and the other end is inserted into the foundation concrete.

[0027] Furthermore, in this embodiment, by setting anchoring steel bars 18, the annular reinforcing plate 9 is firmly connected to the foundation concrete, thereby further improving the connection strength between the anchor plate and the foundation concrete.

[0028] Working principle: During use, the wind turbine tower is connected and fixed to the anchor plate body 1 via bolts and bolt holes 2. The reinforcing rib network 4 on the upper surface of the anchor plate body 1 consists of transverse reinforcing ribs 15 and longitudinal reinforcing ribs 16, which can effectively improve the overall strength and rigidity of the anchor plate body 1 and prevent the anchor plate from deforming under wind loads. At the same time, the reinforcing rib network 4 is integrally formed with the anchor plate body 1, ensuring a firm connection between the reinforcing ribs and the anchor plate body, and avoiding the risk of the reinforcing ribs falling off or breaking.

[0029] The anti-slip protrusions 5 on the lower surface of the anchor plate body 1 increase the friction between the anchor plate and the foundation concrete, preventing the anchor plate from sliding within the concrete. The anti-slip protrusions 5 are triangular prisms, evenly distributed radially along the anchor plate body 1. This design allows the anti-slip protrusions to embed better into the concrete, further improving the connection strength between the anchor plate and the concrete. The annular outer reinforcing flange 6 at the edge of the anchor plate body 1 and the annular inner reinforcing flange 7 at the edge of the central hole 3 increase the strength of the anchor plate's edge and central area, preventing cracking or breakage under wind loads. The height of the outer reinforcing flange 6 and the inner reinforcing flange 7 is higher than the height of the anti-slip protrusions 5. This design allows the anchor plate to better distribute force across the entire anchor plate under load, improving its load-bearing capacity and stability.

[0030] The reinforcing structure 8, located on the outer side of the anchor plate body 1, includes a ring-shaped reinforcing plate 9, a lower reinforcing plate 10, and an upper reinforcing plate 11, which further enhances the overall strength and rigidity of the anchor plate. The reinforcing structure 8 is firmly connected to the anchor plate body 1 through welding or other methods, ensuring the connection strength between the reinforcing structure and the anchor plate body. Simultaneously, the design of the reinforcing structure 8 allows the anchor plate to better distribute force across the entire anchor plate when subjected to wind loads, further improving the stability and safety of the anchor plate.
