Connector, segmented tower, manufacturing method, tower and wind turbine

Abstract

The invention relates to a connection piece, an in-piece tower frame, a manufacturing method, a tower frame and a wind turbine generator system. The connection piece comprises a body portion which comprises a strip-shaped plate and a plurality of connection holes formed in the strip-shaped plate; the strip-shaped plate is provided with a first surface and a second surface which are oppositely arranged in the thickness direction of the strip-shaped itself; the plurality of connection holes are spaced in the length direction of the strip-shaped plate to be arranged; the portions, at the two endsin the length direction, of the body portion are each provided with a connection portion; each connection portion is provided with a first end face and a second end face opposite to each other in thethickness direction; each second end face a smooth curve; the first end face of each connection portion is connected with the first surface and the second end face of each connection portion is connected with the second surface; and in the thickness direction, each second end face at least partially protrudes out of the second surface. According to the connection piece, the in-piece tower frame,the manufacturing method, the tower frame and the wind turbine generator system, the splicing requirement between arc-shaped pieces can be met, the fatigue level of the in-piece tower frame formed dueto splicing can be guaranteed, and then the capacity of the tower frame for bearing the load is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a connector, a sliced ​​tower, a manufacturing method, a tower 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, towers can be used to support parts such as upper impellers and generator sets. 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 arc-shaped pieces for transportation. After arriving at the installation site of the tower, the divided arc-shaped pieces are connected b...

AI Technical Summary

Problems solved by technology

However, the structural design of the connectors used to connect the arc-shaped pieces in the prior art is unreasonable, resulting in a low fatigue level of the segmented tower formed by splicing, which affects the load-bearing capacity of the tower to which it is applied
