Description

Technical Field

[0001] The utility model relates to the field of wind power, in particular to a transition section structure for a tower barrel and a tower column. Background Art

[0002] The tower-to-column transition section connects the wind turbine tower to the lower support structure, ensuring the stability and safety of the entire wind turbine. The transition section effectively transfers forces and moments in the wind turbine superstructure from the tower base to the lower support structure, enhancing the connection stiffness and overall stability of the entire structure.

[0003] Existing towers require frequent maintenance. Workers generally climb from the bottom of the tower column to the top using a fall prevention device, and then enter the tower through the tower manhole to perform maintenance. However, the tower column is generally equipped with multiple safety nodes. When entering the tower from the top of the tower column, the transition section structure is small, making it difficult for workers to step safely, which is prone to safety accidents. At the same time, there are no safety nodes on the tower column, making it difficult to hang the fall prevention device on the safety node. Climbing from the top of the tower column to the transition section platform is also prone to safety accidents. To this end, we propose a transition section structure between the tower and the tower column to solve the above problems. Utility Model Content
