[0028] The embodiments of the technical solutions of the present invention will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0029] Please refer to Figures 1 to 2 , the present invention provides a connected transition section, including a main cylinder 10, corner columns 20, connecting members and a horizontal bar 70.

There are four corner columns 20, and the four corner columns 20 are arranged at the four corners of the periphery of the main cylinder body 10. The connecting members include four main steel beams 40. Each corner column 20 is connected to the side wall of the main cylinder body 10 through a main steel beam 40, and the height of the cross-section of the main steel beam 40 gradually decreases from the main cylinder body 10 towards the corner column 20. Each adjacent two corner columns 20 are connected by a horizontal rod 70.

[0031] During installation, first pack all the parts together, noting that the length, width, and height dimensions of the outer packaging box should not exceed 5 meters. Subsequently, transport the packaged parts to the work site. Then, open the package and take out the corresponding parts. Next, weld and fix the four main steel beams 40 to the main cylinder body 10. Subsequently, initially connect the four corner columns 20 through the horizontal rod 70. Then, weld the four main steel beams 40 to the four corner columns 20. Finally, tighten the connection between the corner columns 20 and the horizontal rod 70.

[0032] For the above-mentioned connected transition section, since the entire transition section does not use concrete, the overall weight of the transition section can be greatly reduced. At the same time, since the parts can be disassembled and packaged for transportation, the size of the packaging box can be greatly reduced, thus facilitating transportation. At the same time, the assembly process of the entire transition section is simple, greatly improving the on-site assembly efficiency.

[0033] In this embodiment, the cross-section of the main steel beam 40 is an H shape, and the H-shaped steel beam has good bending and shear resistance capabilities.

[0034] As a preferred embodiment, the connecting members further include a first upper ring plate 30 and a first lower ring plate 50. The first upper ring plate 30 and the first lower ring plate 50 are respectively sleeved on the middle and bottom of the main cylinder body 10. The upper flange 42 and the lower flange 43 of the main steel beam 40 are respectively connected to the first upper ring plate 30 and the first lower ring plate 50. The connection method is preferably welding. The web plate 41 of the main steel beam 40 is connected to the main cylinder body 10, and the connection method is also preferably welding.

[0035] Through the first upper ring plate 30 and the first lower ring plate 50, the force transmission between the main steel beam 40 and the main cylinder body 10 can be made uniform. During specific implementation, it should be ensured that the widths of the first upper ring plate 30 and the first lower ring plate 50 are both greater than or equal to the width of the upper flange or / and the lower flange of the main steel beam 40. This can improve the uniform force transmission between the main cylinder body 10 and the corner columns 20.

The second upper ring plate 21 and the second lower ring plate 22 are respectively sleeved on the upper and lower ends of the corner column 20. The upper flange 42 and the lower flange 43 are respectively connected to the second upper ring plate 21 and the second lower ring plate 22. Similarly, through the second upper ring plate 21 and the second lower ring plate 22, the force transmission between the main steel beam 40 and the corner column 20 can be made uniform.

[0037] As a further preferred embodiment, this connected transition section further includes a short-leg H-shaped steel beam 80. The short-leg H-shaped steel beam 80 is connected between the second upper ring plate 21 and the second lower ring plate 22, and the web 81 of the short-leg H-shaped steel beam 80 is fixed to the side wall of the corner column 20. The upper flange 42 and the lower flange 43 at the upper and lower ends of the short-leg H-shaped steel beam 80 are respectively connected to the second upper ring plate 21 and the second lower ring plate 22. Through the short-leg H-shaped steel beam 80, it is convenient to connect with the main steel beam 40. In specific implementation, the main steel beam 40 and the short-leg H-shaped steel beam 80 are arranged at the same height, and the main steel beam 40 and the short-leg H-shaped steel beam 80 are connected through a connecting plate 60. The connection method can be through bolts 611.

[0038] In this embodiment, a gusset plate 23 is fixed to the side wall of the corner column 20. Plug plates 71 are arranged at both ends of the horizontal rod 70, and the plug plates 71 and the gusset plate 23 are connected through bolt assemblies 711.

[0039] By adopting the connection method of the plug plate 71 and the gusset plate 23, the two can be conveniently and quickly connected together.

[0040] In addition, the present utility model also provides a wind power tower. This wind power tower includes a lattice steel pipe truss, a tower barrel, and the above-mentioned connected transition section. The connected transition section is used to connect the lattice steel pipe truss and the tower barrel.

[0041] The assembly and use method of this transition section and the wind power tower is as follows:

[0042] Pack and transport all the components of this transition section in a disassembled state to the work site. Subsequently, weld and fix the two first upper ring plates 30 and the first lower ring plates 50 to the main cylinder 10, and then weld and fix one end of the four main steel beams 40 to the first upper ring plate 30, the first lower ring plate 50, and the main cylinder 10. Subsequently, weld and fix the second upper ring plate 21 and the second lower ring plate 22 to the corner column 20, then weld and fix the short-leg H-shaped steel beam 80 to the second upper ring plate 21, the second lower ring plate 22, and the side wall of the corner column 20. Then, pre-connect the plug plate 71 and the gusset plate 23. Then, connect the four main steel beams 40 and the web 81 of the short-leg H-shaped steel beam 80 through a connecting plate 60. Finally, pre-connect and fasten the horizontal rod 70 and the gusset plate 23, and the assembly of the main steel beam 40 outer ring plate connected transition section can be completed.

[0043] When the assembly of the main steel beam 40 outer ring plate connected transition section is completed, connect the lattice steel pipe truss to the four corner columns 20, and connect the tower barrel to the main cylinder 10, then the assembly of the wind power tower can be completed.

[0044] Adopting the above-mentioned main steel beam 40 outer ring plate connection type transition section and the wind power tower, since the whole transition section does not use concrete, the overall weight can be greatly reduced. At the same time, since the parts can be disassembled, packaged and transported, the size of the packing box can be greatly reduced, thus facilitating transportation. At the same time, the assembly process of the whole transition section is simple, greatly improving the on-site assembly efficiency.
