Description

Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to a wind power foundation flange that is easy to construct. Background Technology

[0002] The wind turbine support flange is installed on the foundation and connected to the wind turbine's support flange by bolts. To improve wind resistance, a large number of bolts are installed on the wind turbine support flange. Moreover, to prevent the bolts from rotating, they need to be welded to the wind turbine support flange, resulting in a large amount of on-site construction work and poor consistency in the quality of welding.

[0003] In addition, to improve the stability of the wind turbine foundation flange on the foundation, it can be fixed to the wind turbine foundation flange by welding with steel bars in the foundation, using the steel bars to limit the position of the wind turbine foundation flange. However, because the outer wall of the wind turbine foundation flange is smooth and the contact area with the steel bars is small, it is not conducive to the positioning of the steel bars and welding construction, which affects the reliability of the connection and needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a wind turbine foundation flange that is easy to construct, improves assembly convenience, and facilitates connection with the reinforcing steel in the foundation.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A wind turbine foundation flange that is easy to construct includes: a flange, a first bolt, and a support ring. The flange has a concentrically arranged downward extending cylinder at its bottom edge. The cylinder has a ring array of rebar positioning holes, the axial direction of which extends radially along the cylinder. The support ring is located at the bottom of the flange and inside the cylinder. The first bolt is arranged in a ring array on the support ring and extends upward through the flange.

[0007] The flange is provided with through holes that correspond one-to-one with the first screw.

[0008] The top of the retaining ring is recessed and has a positioning groove corresponding to the head of the first screw.

[0009] The positioning groove is a hexagonal groove.

[0010] The flange and the cylinder are integrated into one structure.

[0011] The support ring is provided with a second screw for connection to the flange.

[0012] The flange has a first reinforcing ring and a second reinforcing ring arranged concentrically on its outer circumference, with the two rings spaced at intervals.

[0013] A stiffening plate is provided between the first reinforcing ring and the second reinforcing ring.

[0014] The beneficial effects of this utility model are as follows: A wind power foundation flange that is easy to construct features a specially designed support ring that can limit the first screw. The positioning groove prevents the first screw from rotating, eliminating the need for welding the first screw and improving the assembly convenience of the first screw. Furthermore, the positioning holes for the reinforcing bars on the cylinder are used to position the reinforcing bars in the foundation, improving the convenience and reliability of welding construction. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model;

[0016] Figure 2 yes Figure 1 Top view. Detailed Implementation

[0017] The following is combined with Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0018] like Figure 1 The wind turbine foundation flange shown is easy to construct and includes: flange 1, first screw 2 and support ring 3. The bottom edge of the flange 1 is concentrically provided with a downwardly extending cylinder 10. In this embodiment, the flange 1 and the cylinder 10 adopt an integrated structure and can be made of steel in one piece, resulting in high structural strength.

[0019] A rebar positioning hole 9 is arranged in a ring array on the cylinder 10. The axial direction of the rebar positioning hole 9 extends radially along the cylinder 10. The rebar positioning hole 9 is used to position the rebar in the foundation, thereby improving the convenience and reliability of welding the rebar to the cylinder 10.

[0020] The support ring 3 is positioned at the bottom of the flange 1 and inside the cylinder 10. The first screws 2 are arranged in a ring array on the support ring 3 and extend upward through the flange 1, as shown below. Figure 2 As shown, the flange 1 is provided with through holes 11 corresponding to the first screws 2 one by one, which facilitates assembly. The large number of through holes 11 can accommodate a large number of first screws 2, and there is no need to weld the first screws 2 on the construction site, which improves the speed of wind power outdoor construction.

[0021] like Figure 1 As shown, the support ring 3 can be used to limit the bottom of the first screw 2, preventing it from sinking. In this embodiment, the support ring 3 is provided with a second screw 4 that connects to the flange 1, resulting in a stable structure.

[0022] Furthermore, a positioning groove 5 corresponding to the head of the first screw 2 is recessed in the top of the retainer 3 to position and conceal the head of the first screw 2. In this embodiment, the positioning groove 5 is a hexagonal groove to prevent the head of the first screw 2 from twisting, thereby improving the stability of the first screw 2.

[0023] To enhance the structural strength of flange 1, a first reinforcing ring 6 and a second reinforcing ring 8 are concentrically arranged on the outer circle of flange 1 at intervals. The first reinforcing ring 6 and the second reinforcing ring 8 are welded and fixed to the outer circle of flange 1, thereby expanding the effective diameter and increasing the contact area with the concrete in the foundation.

[0024] In this embodiment, a stiffening plate 7 is provided between the first reinforcing ring 6 and the second reinforcing ring 8. The stiffening plate 7 is welded and fixed to the outer wall of the flange 1, the surface of the first reinforcing ring 6 and the second reinforcing ring 8, thereby improving the overall structural strength.

[0025] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
