微风发电树装置及风机叶片

本发明公开了一种风机叶片，包括底座和固定在所述底座上的两片弧形的扇叶，每片所述扇叶包括靠近所述底座的中心的内端和朝所述底座的径向伸出的外端，两片所述扇叶的内端的内表面朝向彼此且间隔设置，两片所述扇叶的外端的内表面的朝向相反，两片所述扇叶围成S形的气流通道。本发明还公开了一种微风发电树装置。本发明的风机叶片的扇叶围成可供气流进出的气流通道，在微风环境下即可运转，通过将数量较多的这样的风机叶片布置到微风发电树上后，在各种风向环境下都可以持续供电，而且占地面积小，结构简单，还保证了发电的持续性和稳定性。同时，微风发电树还可以作为城市绿化行道景观树、智慧灯杆等实现多功能的用途。

The invention discloses a wind turbine blade comprising a base and two arc-shaped blade bodies fixed to the base, each blade body comprises an inner end close to the center of the base and an outer end extending in the radial direction of the base, the inner surfaces of the inner ends of the two blade bodies face each other and are arranged in a spaced mode, the directions of the inner surfaces of the outer ends of the two blade bodies are opposite, and an S-shaped airflow channel is defined by the two blade bodies The invention further discloses a breeze power generation tree device. The blade bodies of the wind turbine blade define the airflow channel allowing airflow to enter and exit, the wind turbine blade can operate in a breeze environment, and after a large number of wind turbine blades like this are arranged on a breeze power generation tree, power can be continuously supplied in various wind direction and environments; and besides, the occupied area is small, the structure is simple, and the continuity and stability of power generation are guaranteed. Meanwhile, the breeze power generation tree can also be used as an urban landscaping street landscape tree, an intelligent lamp post and the like to achieve multiple purposes.
