Embodiment 1

[0071] Such as Figure 4-6 It shows a schematic structural view of a sliced ​​fan tower 200 of the present invention, as Figure 4 Shown is the segmented fan tower 200 of the first embodiment. Such as Figure 5 and as Figure 6 As shown, the sliced ​​wind turbine tower 200 of the present embodiment 1 includes 4 longitudinal tower body pieces 22 of equal radian; Side edge; the adjacent longitudinal tower body pieces are fixedly connected by the connecting piece, and the fixed connecting piece in this embodiment is a bolt set. In the sliced ​​fan tower of the present invention, when the longitudinal tower body pieces are n pieces, the radian of each of the longitudinal tower body pieces is 360° / n, that is, in this embodiment, the longitudinal tower body When there are 4 pieces, the arc of each longitudinal tower body piece is 90°.

[0072] Further, the shape of the segmented fan tower is a cylinder, or the shape of the segmented fan tower is a cone. Such as Figure 4-6 As...

Embodiment 2

[0074] In Embodiment 2 of the present invention, the sliced ​​fan tower in Embodiment 2 is similarly consistent with n pieces of the longitudinal tower body, and the arc of each longitudinal tower body is 360° / n. condition. In Embodiment 2 of the present invention, the n of the longitudinal tower body pieces 22 is 3 pieces, so the radian of each of the longitudinal tower body pieces is 120°, except that different tower body pieces 22 are used, other The structures of the sliced ​​fan towers 200 in Embodiment 1 of the invention are basically the same.

Embodiment 3

[0076] Such as Figure 7-10 The manufacturing method of the sliced ​​fan tower is shown. Such as Figure 7 Shown, the manufacturing method of described sliced ​​fan tower, it comprises the following steps:

[0077] Step 300, steel plate rolling: roll the steel plate circumferentially into a tower body section, and fix the vertical connection seam on the tower body section by spot welding to form a vertical weld line;

[0078] Step 301, stacking tower body sections: stacking several tower body sections vertically, taking the vertical weld line of adjacent tower body sections as a reference, and the angle between adjacent tower body sections is k×360° / n;

[0079] Among them, k is an integer, 0, 1, 2, 3...

[0080] And, if the longitudinal tower body slices of the sliced ​​fan tower are designed as n slices, the arc of each slice is 360° / n;

[0081] Step 302, flange installation: install flanges on the top of the stacked top tower body section and the bottom end of the stac...

Abstract

The invention discloses a multi-sheet type fan tower and a manufacturing method and a transporting method thereof. The multi-sheet type fan tower comprises a plurality of longitudinal tower body sheets equal in radian and a plurality of connecting pieces which are fixedly arranged at the end edges of two sides of the longitudinal tower body sheets, wherein the adjacent longitudinal tower body sheets are fixedly connected through the connecting pieces. The radian of each of the n longitudinal tower body sheets is 360 degrees / n. The invention also discloses a manufacturing method and a transporting method of the multi-sheet type fan tower. According to the multi-sheet type fan tower, the welding workload is reduced, the non-destructive testing cost is lowered, and the welding quality risk isavoided; moreover, the butt weld quantity of the tower is reduced, and the damage of restraint intensity and stress concentration of the tower structure is alleviated, so that the service life of thetower is prolonged. In addition, the multi-sheet type structure brings hoisting and transporting convenience.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a sliced ​​wind turbine tower, a manufacturing method and a transportation method thereof. Background technique [0002] Wind energy is a renewable and clean energy, which has played a positive role in promoting energy conservation, emission reduction, environmental protection, and alleviating energy shortages. With the continuous development of wind power generation, it is a development trend to increase the power of a single unit. [0003] Such as figure 1 and figure 2 As shown, the tower 100 is an important component of the wind turbine, and is composed of a multi-section tower. The tower is assembled from a plurality of fan-shaped steel plates 11 rolled into a cylindrical section 13. The main process of manufacturing the tower is as follows : [0004] First, if figure 2 As shown, steel plates of different thicknesses are cut and blanked into fan-shaped st...
