Abstract

The utility model relates to a slideway type wind blade system of a vertical wind power generator, which relates to a wind blade system of a vertical wind power generator. The present invention aims to solve the problem of large starting dead angle and large reversing dead angle in the starting and rotating motion of the existing fan blade, and the problem that the airfoil fan blade has a small wind-receiving area and is difficult to increase the capacity. Scheme 1 is a single-layer fan blade system. There are three single fan blades connected between the connecting flanges of the two shaft fan blades. The three single fan blades are ring-shaped around the compound shaft. The body blades are arranged at an angle of 120 degrees. The upper and lower ends of the three single blades are fixedly connected by a triangular blade fixing frame, and a blade pulley is installed at the lower end of each single blade. The blade annular slideway is fixedly installed on the frame beam, and the fan blade pulley slides on the slideway. The difference between Scheme 2 and Scheme 1 is that it is a double-layer fan blade system. The difference between Scheme 3 and Scheme 1 is that it is a multi-layer fan blade system. The invention is used in wind power generation.

Description

technical field [0001] The invention relates to a wind blade system of a vertical wind power generator, in particular to a slideway type wind blade system of a vertical wind power generator, which belongs to the technical field of wind power generation. Background technique [0002] With the development of the world's energy crisis, the use of wind kinetic energy as a new energy source for the development of modern society has become a hot spot in social development. The traditional three-blade wind turbine has no wind collection and protection system, the utilization rate of wind power is low, the volume of the wind turbine is large, and the long blades are difficult to transport, install and maintain, and are easily damaged. The blades of the existing vertical wind turbines have the problem of large start-up dead angle and large reversing dead angle during startup and rotation. , There is a commutation dead angle in the rotary motion, and it is difficult to increase the c...
