Description

Technical Field

[0001] The invention relates to the technical field of offshore power generation, and in particular to an offshore wind power tower docking mechanism. Background Art

[0002] The wind turbine tower is the tower of the wind turbine generator set. It mainly plays a supporting role and can also absorb the vibration of the generator set. It plays a vital role in the entire wind turbine generator set. The tower consists of multiple sections that are welded in sequence along the vertical direction. In order to facilitate transportation, the tower is generally assembled on site. However, due to the large overall height and weight of the tower, the tower also needs the assistance of a crane during installation. In this way, when the upper section lifted by the crane is welded with the lower section fixed on the ground, it is necessary to ensure that the edges of the two contact overlap; At present, most tower positioning devices use slots and clamping rings for positioning. Although this structure can improve the positioning accuracy between the upper and lower sections, it still needs to be maintained manually when the upper section is shaking stably. As a result, it takes a long time to connect the upper and lower sections. For workers, the long-term stable shaking of the upper section will increase the labor intensity of the workers and make it difficult to maintain. Summary of the invention
