Problems solved by technology

The blades of the horizontal axis wind turbine generally need to face the wind direction to receive the wind. When facing the wind direction, the thrust of the wind force on the blades is an oblique thrust. In addition, the gap between the blades gives up part of the wind energy in vain, improving the utilization efficiency. It is relatively low, and cannot use 100% of the wind force within the effective range like a sail; and when a large

Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment.

[0019] like figure 1 , figure 2 As shown, the fan blade mechanism of the wind power generator of the present invention is mainly composed of a fixed bracket 1, a central shaft 2, a central pillar, six fixed blades 4 and movable blades 5 that are axially connected with the fixed bracket shaft 3, and the fixed bracket 1 It is composed of arc-shaped rods that are equicircumferential and radial, and there are two upper and lower ones. The fixed bracket shaft 3 is arranged at each radial end of each fixed bracket 1, and the fixed blade 4 is arranged between the central axis 2 and the fixed bracket shaft 3. The movable vane 5 takes the fixed support shaft 3 as the movable axis. The movable vane 5 is arc-shaped, and the outer end is provided with an outwardly curved wind guide edge 6; the inner side of the movable vane 5 protrudes slightly, and fits with the joint of the fixed vane 4; th...

Abstract

The invention discloses a fan blade mechanism of a wind driven generator, which is arranged on the upper part of a vertical shaft wind driven generator. The fan blade mechanism is characterized by mainly comprising fixed brackets, a center shaft, a center support column, a plurality of fixed blade plates and movable blade plates, wherein the fixed blade plates are connected with the fixed bracket shafts; the upper and lower fixed brackets or more than two fixed brackets are in equal circumferential radial structures; the fixed bracket shafts are arranged on the radial end of each fixed bracket; the fixed blade plates are arranged between the center shaft and the fixed bracket shafts; and the movable blade plates use the fixed bracket shafts as movable shafts and are attached to the connection positions of the fixed blade plates. The fan blade mechanism has simple structure, high wind energy utility ratio, and the like.

Description

technical field [0001] The invention belongs to the field of wind power generators, in particular to a fan blade mechanism suitable for wind power generators. Background technique [0002] Existing wind turbines are mainly divided into the following two types according to the different blade forms: the horizontal axis type is the main form of wind power generation because of its simple structure and is widely used; Higher than the horizontal axis wind turbine, no noise and steering mechanism, easy maintenance, more and more applications. The blades of the horizontal axis wind turbine generally need to face the wind direction to receive the wind. When facing the wind direction, the thrust of the wind force on the blades is an oblique thrust. In addition, the gap between the blades gives up part of the wind energy in vain, improving the utilization efficiency. It is relatively low, and cannot use 100% of the wind force within the effective range like a sail; and when a large ...
