Tower drum segment, tower drum, segmentation method and wind turbine generator set

Abstract

The present invention relates to a tower drum segment, a tower drum, a segmentation method and a wind turbine generator set. The tower drum segment comprises an annular body with two opposite end faces in the axial direction thereof, wherein the annular body is formed by splicing a plurality of tower drum sheets, and a receiving slot extending along the axial direction is arranged between two adjacent tower drum sheets; and connecting pieces, by which two adjacent tower drum sheets are connected with each other, wherein the connecting pieces comprise first connecting pieces and second connecting pieces which can be detachably connected with each other; sides of the first connecting pieces, far away from the second connecting pieces, are fixedly connected to the inner annular surface and outer annular surface of one of two adjacent tower drum sheets; and sides of the second connecting pieces, far away from the first connecting pieces, are fixedly connected to the inner annular surface and outer annular surface of the other of two adjacent tower drum sheets. According to the tower drum segment, the tower drum, the segmentation method and the wind turbine generator set, the tower drumsheets are simply connected when being spliced with each other, and a small splicing gap between the tower drum sheets is present, and thus the load bearing capacity of the tower drum can be ensured.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a tower section, a tower, a division method and a wind power generating set. Background technique [0002] Tower is an important structural form of towering structures, and it is widely used in transmission towers, TV towers, cooling towers and other fields. Especially in the field of wind power generation, the tower can be used to support parts such as the upper impeller and the generator set. As the power of the wind turbine increases, the diameter of the impeller becomes larger, and the height of the corresponding tower is also higher and the cross-sectional size is also larger. [0003] In order to meet the requirements of the transportation height limit, the large-diameter tower is usually divided into pieces to form multiple tower pieces for transportation. After arriving at the installation site of the tower, the pieced tower pieces are assembled Rebuild the tower. H...

Problems solved by technology

However, in the prior art, the connectors used to connect the tower segments are unreasonably set up, resulting in greater damage to the tower segments when they are connected to the corresponding tower segments, so that the tower segments are spliced ​​with each other. When the connection is difficult and gaps are likely to appear, it will affect the ability of the tower to bear the load
