[0033] This embodiment provides a wind power foundation mold, see reference. Figures 1-5 As shown, the structure includes two semi-circular base plates 1. The upper surfaces of the semi-circular base plates 1 are respectively provided with a first fixing post 11 and a second fixing post 12. The first fixing post 11 is used to be inserted into the perforated plate 2. The two ends of the perforated plate 2 are respectively provided with a first insertion hole 21. The second fixing post 12 is used to be inserted into the second insertion hole 31 at the bottom end of the first side wall plate 3. The first side wall plate 3 surrounds the upper ends of the two semi-circular base plates 1 to form a casting cavity. A reserved hole 13 is opened at the center of the two semi-circular base plates 1, and a pile hole pipe 4 is inserted into the reserved hole 13.

[0034] In the above embodiment, the bottom of the mold is formed by connecting two semi-circular bottom plates 1, and the upper end surface of the semi-circular bottom plates 1 is respectively provided with a first fixing post 11 and a second fixing post 12. The two ends of the perforated plate 2 are respectively provided with a first insertion hole 21. When connecting the two semi-circular bottom plates 1, the first insertion holes 21 at both ends of the perforated plate 2 are respectively fitted with the first fixing posts 11 adjacent to the two semi-circular bottom plates 1, so that the two semi-circular bottom plates 1 are connected through the perforated plate 2 to form a whole mold bottom plate. Compared with a complete mold bottom plate, splicing two semi-circular bottom plates 1 reduces the volume of the bottom plate when the mold is transported, making the bottom plate of the mold easier to transport and improving the transport efficiency of the mold. The second fixing column 12 is used to connect with the second insertion hole 31 at the bottom of the first side wall plate 3. Multiple first side wall plates 3 are inserted into the upper surface of the two connected semi-circular bottom plates 1 through the second fixing column 12 to form a casting cavity. Concrete can be poured into the casting cavity. On the one hand, the concrete is pressed tightly against the bottom surface of the mold under the action of gravity, which improves the stability of the bottom of the mold. Moreover, the casting mold is assembled from multiple components, which reduces the space occupied by the mold during transportation compared with the one-piece casting mold, making it easier to transport and assemble, and improving the transfer efficiency of the mold. On the other hand, the mold can be mass-produced in fixed sizes, so that the shape and size of the concrete after pouring can be accurately controlled when pouring the wind power foundation in the mold. This reduces the operational errors of manual excavation of the foundation pit for pouring, avoids rework and repair costs caused by construction quality problems, ensures the actual foundation pouring quality, and ensures that the shape, size and surface quality of the wind power foundation structure meet the design requirements. This is beneficial to improving the stability of the wind turbine in later operation. The mold can be mass-produced, which enables the batch pouring construction of wind power foundations, helps to shorten the construction period and reduce construction costs. In addition, a reserved hole 13 is provided at the center of the two semi-circular bottom plates 1, and a pile hole pipe 4 is inserted into the reserved hole 13. This allows the pile hole pipe 4 to leave a pile hole in the center of the pouring process in the mold cavity, which is used for the later installation of the support piles of the wind turbine. This eliminates the need to drill holes in the wind turbine foundation after pouring, thereby improving the installation efficiency of the wind turbine.

[0037] In one embodiment of the present application, referring to Figure 3 As shown in the figure, the side edge of the connecting plate 5 is provided with an arc panel 52.

[0038] In the above embodiment, the arc panel 52 provided on the side edge of the connecting plate 5 is in contact with the side wall of the pile hole pipe 4 for supporting the pile hole pipe 4, preventing the pile hole pipe 4 from being pushed and tilted by the impact of the concrete during the pouring of the pouring cavity, and being beneficial to improve the stability of the mold during pouring.

[0039] In one embodiment of the present application, referring to Figure 4 As shown in the figure, the upper end surface of the connecting plate 5 is provided with a plurality of mounting holes 53.

[0040] In the above embodiment, a plurality of mounting holes 53 are provided between the third insertion holes 51 at the two ends of the connecting plate 5, and the mounting holes 53 are used for providing mounting points for the vibrating rod, which vibrates the concrete in the pouring cavity, so that the components of the concrete are more evenly distributed, the compactness of the concrete is improved, and the forming quality of the concrete is improved.

[0041] In one embodiment of the present application, referring to Figure 2 As shown in the figure, the bottom surface of the semicircular bottom plate 1 is provided with a ground pile 6.

[0042] In the above embodiment, the ground pile 6 is pre-buried underground, which is used for providing upward support for the semicircular bottom plate 1 to prevent the poured concrete from pressing the bottom plate and causing the bottom plate to sink, thereby causing the mold to tilt, and improving the stability of the mold during pouring.

[0043] In one embodiment of the present application, referring to Figure 3 As shown in the figure, the side surface of the ground pile 6 is connected with an inclined plate 61.
