Document Type and Number:
WIPO Patent Application WO/2019/128052
Kind Code:
A1
Abstract:
A segmented blade, which comprises: a first blade segment (100) which has a first main beam (150), wherein the first blade segment (100) is at a side close to a blade root, and the first main beam (150) comprises a first body portion (130) disposed within the first blade segment (100) and a first engaging portion (140) extending from an end portion of the first body portion (130) toward a direction (D1) which is away from the blade root, the height of the first engaging portion (140) gradually decreasing along the direction (D1) away from the blade root; a second blade segment (200) which has a second main beam (250), wherein the second blade segment (200) is at a side close to a blade tip, and the second main beam (250) comprises a second body portion (230) disposed within the second blade segment (200) and a second engaging portion (240) extending from an end portion of the second body portion (230) toward a direction (D3) which approaches the blade root, the height of the second engaging portion (240) gradually increasing along the direction (D3) which approaches the blade root, wherein, and the second engaging portion (240) being engaged in the first engaging portion (140); and an outer skin (400), which covers a gap (G) between the first blade segment (100) and the second blade segment (200). The segmented blade fundamentally does not increase the weight of the blade and provides a highly reliable connection. Also provided are a method for connecting segmented blades and a wind power generator set.
