Tower section, tower, division method and wind turbine

Abstract

The invention relates to a tower section, a tower section, a division method, and a wind power generating set. The tower section includes: an annular body with two opposite end faces in the direction of its own axis, and the annular body is composed of a plurality of towers It is formed by splicing pieces, and accommodating grooves extending along the axis direction are arranged between two adjacent tower tube segments. Connecting pieces, two adjacent tower tube pieces are connected to each other through connecting pieces, and the connecting pieces include mutually detachable The connected first connecting piece and the second connecting piece, wherein, the side of the first connecting piece away from the second connecting piece is fixedly connected to the inner ring surface and the outer ring surface of one of two adjacent tower tube segments, the second The side of the two connecting pieces away from the first connecting piece is fixedly connected to the inner ring surface and the outer ring surface of the other of the two adjacent tower tube segments. The tower section, the tower, the division method and the wind power generation unit involved in the present invention, when the tower sections are spliced ​​with each other, the connection is simple and the splicing gap between them is small, which can ensure the load bearing capacity of the tower.

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
