Document Type and Number:
WIPO Patent Application WO/2018/049826
Kind Code:
A1
Abstract:
A shielding blade supporting piece type vertical axis wind turbine, comprising a wind wheel rotating around a vertical rotation axis and a bearing body (3) determining the vertical rotation axis. The wind wheel comprises a wheel frame (1) and blades (2) distributed on the periphery of the wheel frame (1), the wheel frame (1) being rotatably connected to the bearing body (3); the upper portion and the lower portion of the wheel frame (1) are respectively provided with a group of blade supporting pieces, a baffle (P) being separately connected to the tail section or the tail end of each blade supporting piece distant from the vertical rotation axis; the baffle (P) is located between the tail section of the corresponding blade supporting piece and the corresponding blade (2), or the edge of the baffle (P) and the tail end of the corresponding blade supporting piece are integrally formed; the baffle (P) at the upper portion of the wheel frame (1) corresponds to the baffle (P) at the lower portion of the wheel frame (1) up and down, and the corresponding blades (2) are connected between the corresponding baffles (P); two ends of the blade (2) are connected to the corresponding baffles (P) directly or by means of a connecting piece. By improving the structure of the wind wheel, especially the mounting structure of the blades (2), the driving force of the blades (2) and the wind energy utilization efficiency can be improved.
