Abstract
The utility model relates to a blade device of a wind power generator. When the wind is blown to blades of the wind power generator, the wind is divided into power wind and resistance wind. A wind shield stops the resistance wind, so that the power generating efficiency of the generator can be improved; the blade device is provided with a skeleton and a supporting column, so that the capacity of the blade for resisting the heavy typhoon can be improved; and the arc blades can make the wind be concentrated to the middle part of the blades.
Description
Technical field
The utility model belongs to wind-power electricity generation, is specifically related to a kind of fan blade device of wind-driven generator.
Background technique
Wind-driven generator is of a great variety at present; Like Chinese utility model patent number: ZL201020298538.2; August 20 2010 applying date, publication number CN201810484U, open day on April 27th, 2011; A kind of " vertical wind driven generator that has barge board " of IPC classification number F03D9/00:F03D7/06:F03D3/04:F03D3/06, this power-driven generator leaf sheet periphery are provided with an intelligent arrow type barge board.When wind-force blows to the fan blade of this wind-driven generator, just be divided into power wind and resistance wind, the wind-force that blows to fan blade upper half part is power wind, the wind-force that blows to fan blade lower half portion is resistance wind.This intelligence arrow type barge board is to keep off in the middle of fan blade, does not therefore block resistance wind.
Summary of the invention
For the barge board that overcomes existing technology can not block the deficiency of resistance wind, the utility model provides a kind of fan blade device that can block the wind-driven generator of resistance wind.
In order to reach above purpose; The utility model is realized through following technological scheme: a kind of fan blade device of wind-driven generator, form by air blade and barge board, and it is characterized in that; Barge board is a circular arc; Barge board is arranged on the cambered surface of 45 degree of fan blade lower half portion, and the behind of fan blade is provided with skeleton and pillar, and the fulcrum of pillar is to be fixed on the skeleton and the front of back a slice fan blade.
The effect of barge board is to have blocked the resistance wind that blows to fan blade, has therefore improved the power benefit of wind-driven generator, and fan blade is provided with after skeleton and the pillar, has improved the ability of the anti-violent typhoon of fan blade.
As preferably, the shape of fan blade is a circular arc.
The shape of fan blade is arranged to circular arc, can make wind concentration blow the centre to fan blade, and wind-force is scatter.
Beneficial effect is: barge board has blocked the resistance wind that blows to fan blade, has improved power benefit, is provided with on the fan blade after skeleton and the pillar, has improved the ability of the anti-violent typhoon of fan blade, and the air blade of circular arc can make wind concentration blow the centre to fan blade.
