[0002] As society's demand for energy continues to increase, wind energy, as an important clean and renewable energy source, accounts for an increasing proportion of wind power generation. As the capacity of wind turbines continues to increase, ultra-high towers have become a trend. As the supporting structure of the entire wind turbine, the tower is subject to increasing loads. In order to meet the requirements for safe operation of wind turbines, the tower design diameter needs to be increased. The integral large-diameter tower is difficult to transport, while the segmented tower solves the problem of transportation difficulties.

[0039] The core of the utility model is to provide a segmented tower, which is assembled in a segmented splicing manner, and can be conveniently transported and installed.

[0040] In order to enable those skilled in the art to better understand the technical solution of the utility model, the segmented tower of the utility model will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Combination Figure 1 , Figure 2 As shown, the utility model provides a segmented tower, which includes a plurality of cylinder segments 1 and a plurality of platform segments 2, at least three cylinder segments 1 can be combined to form a cylinder, and a cylinder is a complete annular cylindrical structure; Figure 1 As shown therein, a cylinder is formed by three cylinder segments 1, each cylinder segment 1 is a section of arc-shaped surface, and the shape of the entire wind turbine tower is a cylindrical surface or a conical surface. The size of its cross-section will change along the height direction of the tower. The outer surface of the tower is formed by splicing several cylinders, and each cylinder is consistent with the shape of the tower where it is located.

[0042] More than three cylinder segments 1 are arranged around the cylinder, and the length of the cross section of each cylinder segment 1 is smaller than the diameter of the entire cylinder, which is convenient for transfer and transportation. Usually, each cylinder segment 1 is arranged symmetrically, and each cylinder segment 1 has the same structure, which can be easily processed and produced.

[0043] At least three platform segments 2 can be combined to form a continuous flange platform for people to walk on; each layer is provided with more than three platform segments 2, combined with Figure 2 , Figure 8 , Fig. 9 As shown, three platform segments 2 are provided as an example. The platform segments 2 are spliced ​​to form a platform structure with a hollow middle area, which can be used for people to walk, and operators can stand on the platform to perform assembly operations; the hollow area in the middle of the platform can be used for equipment hoisting, and the weight of the platform is reduced; the platform formed by splicing several platform segments 2 is a discontinuous annular structure with a notch, and the notch is used to avoid the ladder set on the inner wall of the cylinder.

[0044] At least one platform segment 2 is arranged corresponding to each cylinder segment 1. Generally, the cylinder segments 1 and the platform segments 2 are arranged one to one, and each platform segment 2 is fixed to one cylinder segment 1; however, the utility model does not exclude the arrangement of one cylinder segment 1 corresponding to two platform segments 2, or the installation of three platform segments 2 corresponding to two spliced ​​cylinder segments 1.

[0045] The cylinder segment 1 and the corresponding platform segment 2 can be independently fixed and spliced ​​to form an installation splicing section. Before assembling to form a tower, the cylinder segment 1 and the corresponding platform segment 2 are first connected and fixed relative to each other, and then the various installation splicing sections are spliced ​​and fixed to each other to finally form a section of the tower structure. Multiple sections of the tower are spliced ​​and fixed one by one, stacked layer by layer, and finally form the entire tower.

[0046] Combination Figure 8 , Fig. 9As shown, the platform segment 2 includes a platform beam 21 and a platform plate 22. The platform beam 21 is a frame structure. The platform plate 22 is installed on the platform beam 21. The platform beam 21 is used to support the platform plate 22. The platform plate 22 is used for people to stand and walk. The platform beam 21 is fixed to the inner surface of the cylinder segment 1 through the support 3, and the platform beam 21 plays the main function of bearing the force. Among the platform plates 22 of the same platform segment 2, the adjacent platform plates 22 are relatively fixedly connected. Since the platform plates 22 are connected to each other as a whole, the gravity borne by one platform plate 22 is shared to other platform beams 21. That is to say, when the operator stands on a certain platform plate 22, the gravity generated by it is not only borne by the platform beam 21 directly below it, but also transmitted to other platform beams 21 through the platform plates 22 that are connected to each other, so as to achieve a better support effect. The platform beams 21 can be relatively fixed or independently set.

[0047] The utility model adopts the segmented splicing method with the advantage of stacking and transportation. The segmented structure can be assembled separately and synchronously on site, shortening the installation period. The installation convenience of the flange platform is improved, and the gravity of one platform segment can be shared by other platform segment beams, improving the support strength. When installing the cylinder segment 1 and the platform segment 2, there is no need to stand them up, eliminating the tooling required for the erection and installation of the tower body, reducing the tooling cost of the entire tower.

The first support portion 31 and the second support portion 32 can be fixedly connected by splicing bolts 33 to achieve relative connection, and the first support portion 31 supports the second support portion 32 and the platform segment 2 above it.
