Background

In electric power and energy science, a wind wheel refers to a wind turbine component for converting wind energy into mechanical energy. Consists of blades and a hub. In traditional Chinese medicine, the wind wheel refers to a cornea part; wind wheels are diverse, but can be classified into two categories: a horizontal shaft wind wheel, the rotation axis of which is parallel to the wind direction; the rotation axis of the vertical axis wind wheel is vertical to the ground or the airflow direction. There are several types of vertical axis wind wheels that use resistance rotation, among which are wind wheels made of flat plates and quilts, which is a pure resistance device; the S-shaped wind wheel has partial lifting force, but is mainly a resistance device, and is a main competitor of the horizontal-axis wind wheel. Other forms of vertical axis wind wheels include magnus effect wind wheels and the like.

The existing wind wheel basic structure at least comprises a main shaft, a frame, a sub-shaft and blades. The main shaft is in the frame center, and the blades are generally integrally welded into a circumference distribution shape, and are generally installed with the hub and then fixed through bolts between the hub and the main shaft, so that when the blades need to be replaced, the hub can be detached only by unscrewing the bolts, and then the blades are integrally replaced, in the use process of the wind wheel, the blades can be worn due to impurities at the air inlet and the air outlet, if the worn blades need to be replaced, the blades need to be integrally replaced, one or more blades cannot be replaced independently, and therefore, more capital is consumed for maintenance.
