In the wind-driven generator, the complex structure of horizontal axial type wind-driven generator, generating efficiency is high; Perpendicular axis type wind-driven generator simple in structure, generating efficiency is lower, and the modal situation that affects generating efficiency is that wind blows to simultaneously symmetrical two wind acanthus leafs and causes wind-force to offset in perpendicular axis type wind-driven generator.
The model utility content
Technical problem to be solved in the utility model provides the vertical shaft type wind power generation device that a kind of wind only blows to half wind acanthus leaf.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of wind generating unit, support post is the hollow cylinder body structure, three support posts are fixedly mounted on ground, generator support is comprised of three cylindrical bars that are parallel to ground, one end of each cylindrical bar connects support post, the other end connects generator, and the rotor shaft of generator extends to beyond the generator;
A fan blade base plate is installed on three above-mentioned support post tops, the fan blade base plate is the cylindrical body platy structure, through hole is offered at fan blade base plate center, bearing is installed in the through hole hole wall, blade shaft passes this bearing and extends to the fan blade floor below, is connected by coupling with the rotor shaft of generator at blade shaft;
The part of blade shaft more than the fan blade base plate installed mutually perpendicular two wind acanthus leafs, and wind acanthus leaf is the cuboid platy structure, and wind acanthus leaf is divided into four little wind acanthus leafs centered by blade shaft, and every adjacent two wind acanthus leaf angles are 90 degree;
This wind generating unit also is equipped with a barge board, the cross section of barge board is quadrant annular shape, barge board is installed in the edge of fan blade base plate, be installed in the both sides of fan blade base plate with the diagonal symmetry, the height of barge board is more than or equal to the height of wind acanthus leaf, and barge board is extended to another wind acanthus leaf that is adjacent by a wind acanthus leaf.
Further be: above-mentioned barge board is removable to be installed on the described fan blade base plate.
The beneficial effects of the utility model are:
The utility model wind generating unit by the setting of barge board, has avoided wind to blow to simultaneously the phenomenon that symmetrical two little wind acanthus leafs cause wind-force to offset, and has improved the generating efficiency of perpendicular axis type wind-driven generator.And above-mentioned barge board can take off when wind-force is larger, reduces the fan blade rotating speed, whole device has been played the effect of protection.

Embodiment
Below in conjunction with drawings and Examples the utility model embodiment is described:
Fig. 1,2 shows the utility model one embodiment's structure, as shown in the figure, in the utility model, support post 1 is the hollow cylinder body structure, three support posts 1 are fixedly mounted on ground, and generator support 4 is comprised of three cylindrical bars that are parallel to ground, and an end of each cylindrical bar connects support post 1, the other end connects generator 3, and the rotor shaft 2 of generator 3 extends to beyond the generator.A fan blade base plate 9 is installed on three above-mentioned support post 1 tops, fan blade base plate 9 is the cylindrical body platy structure, through hole is offered at fan blade base plate 9 centers, bearing is installed in the through hole hole wall, blade shaft 5 passes this bearing and extends to fan blade base plate 9 belows, is connected by coupling at the rotor shaft 2 of blade shaft 5 and generator 3.Blade shaft 5 is installed mutually perpendicular two wind acanthus leafs 6 in the part of fan blade base plate more than 9, and wind acanthus leaf 6 is the cuboid platy structure, and wind acanthus leaf 6 is divided into four little wind acanthus leafs centered by blade shaft 5, and every adjacent two wind acanthus leaf angles are 90 degree.As shown in Figure 1, above-mentioned wind generating unit also is equipped with a barge board 8, the cross section of barge board 8 is quadrant annular shape, barge board 8 is installed in the edge of fan blade base plate 9, be installed in the both sides of fan blade base plate 9 with the diagonal symmetry, the height of barge board 8 is more than or equal to the height of wind acanthus leaf 6, and barge board 8 is extended to another wind acanthus leaf that is adjacent by a wind acanthus leaf.
