Abstract

The utility model relates to a blade for a vertical axis wind generator, which is made up of a main fan blade 1, an accessory shaft 2, an auxiliary fan blade 3, a connecting bar 4, and a main shaft 5, wherein, one side of the rear wing part of the main fan blade 1 is vacant, the accessory shaft 2 is arranged at the rear wing vacant part of the main fan blade 1, the auxiliary fan blade 3 is added to the accessory shaft 2, the main fan blade 1 and the auxiliary fan blade 3 on the accessory shaft 2 are connected with the main shaft 5 through the connecting bar 4 to form a whole, the rear wing end of the main fan blade 1 is connected with the accessory shaft 2, and the auxiliary fan blade 3 is opened or closed around the accessory shaft 2. Beyond the advantages of simple structure and convenient use, the device enables the fan blades to make use of wind resistance and life force in reducing start-up wind speed and improving wind energy conversion efficiency.

Description

Vane of vertical shaft wind-driven generator
Technical field
The utility model relates to wind power generating set, and the blade structure relates in particular to a kind of blade that is used for vertical axis aerogenerator.
Background technique
Usually, the wind-power electricity generation blower fan divides horizontal axis blower fan and vertical shaft fan, for vertical shaft fan, known favourablely is used in the windage difference that produces on the blade and the resistance type blower fan that rotates and the lift that produces and the lift-type blower fan that rotates on blade; But mostly have fan starting wind speed height, the effective wind speed scope is little, causes shortcomings such as the wind energy conversion efficiency is low
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and a kind of vane of vertical shaft wind-driven generator is provided, and on the fan blade of vertical shaft fan, improved, can effectively reduce the startup wind speed, can be in efficient power generation in the wind speed zone on a large scale, thereby improved the wind energy conversion efficiency.
For realizing described purpose, the technical solution adopted in the utility model is: a kind of vane of vertical shaft wind-driven generator, and by main blade (1), noncoupled axle (2), auxiliary fan blade (3), connecting rod (4), main shaft (5) is formed; The rear wing position of main blade (1) is set to a side vacancy, is provided with noncoupled axle (2) in the rear wing vacancy portion of main blade (1), has installed auxiliary fan blade (3) on noncoupled axle (2) additional; Auxiliary fan blade (3) on main blade (1) and the noncoupled axle (2) thereof connects into integral body by connecting rod (4) and main shaft (5).
The back wing tip of described main blade (1) is connected with noncoupled axle (2).
Described auxiliary fan blade (3) is to open or closure around noncoupled axle (2).
The utlity model has following advantage:
1, simple in structure, easy to use;
2, the rear wing vacancy position of main blade installs auxiliary fan blade additional, makes fan blade utilize windage and lift simultaneously;
3, reduce the startup wind speed, improved the wind energy conversion efficiency;
Description of drawings
Fig. 1 is a structure connection diagram of the present utility model
Among the figure, 1-main blade, 2-noncoupled axle, the auxiliary fan blade of 3-, 4-connecting rod, 5-main shaft, A-windage, arrow → B, C, D-are wind direction;
Embodiment
Below in conjunction with drawings and Examples the utility model is further described
With reference to Fig. 1, a kind of vane of vertical shaft wind-driven generator is made up of main blade 1, noncoupled axle 2, auxiliary fan blade 3, connecting rod 4, main shaft 5; The rear wing position of main blade 1 is set to a side vacancy, is provided with noncoupled axle 2 in the rear wing vacancy portion of main blade 1, has installed auxiliary fan blade 3 on noncoupled axle 2 additional; Auxiliary fan blade 3 on main blade 1 and the noncoupled axle 2 thereof connects into integral body by connecting rod 4 and main shaft 5; Rotation by main shaft 5 drives generator for electricity generation.The back wing tip and the noncoupled axle 2 of described main blade 1 are bolted to connection; Described auxiliary fan blade 3 is opened or closure around noncoupled axle 2.
During work, when blower fan when wind is arranged, the auxiliary fan blade 3 on the resistance area main blade 1 will be opened around noncoupled axle 2, together with main blade 1 rear wing one side vacancy interruption-forming resistance area, by wind resistance main blade 1 is rotated by connecting rod 4 around main shaft 5, effectively improve and start wind speed.After main blade 1 whiz Resistance Level, auxiliary fan blade 3 is promptly closed because of windage, forms a complete combination fan blade with main blade 1, and the combination fan blade is by the lift rotation.This combination fan blade had both utilized windage like this, had utilized lift again, thereby had improved the wind energy conversion efficiency greatly.

Claims (3)

1, a kind of vane of vertical shaft wind-driven generator, by main blade (1), noncoupled axle (2), auxiliary fan blade (3), connecting rod (4), main shaft (5) is formed; It is characterized in that: the rear wing position of main blade (1) is set to a side vacancy, is provided with noncoupled axle (2) in the rear wing vacancy portion of main blade (1), has installed auxiliary fan blade (3) on noncoupled axle (2) additional; Auxiliary fan blade (3) on main blade (1) and the noncoupled axle (2) thereof connects into integral body by connecting rod (4) and main shaft (5).
