In the wind-driven generator, the complex structure of horizontal shaft 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 influences generating efficiency is that wind blows to symmetrical two wind acanthus leafs simultaneously and causes wind-force to offset in perpendicular axis type wind-driven generator.
Summary of the invention
Technical problem to be solved by this invention provides the vertical shaft type wind power generation device that a kind of wind only blows to half wind acanthus leaf.
The technical solution adopted for the present invention to solve the technical problems is: a kind of wind generating unit; Support post is the hollow cylinder body structure; Three support posts are fixedly mounted on ground, and generator support is made up of three cylindrical bars that are parallel to ground, and an 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, and blade shaft passes this bearing and extends to the fan blade floor below, is connected through 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 that the center is divided into four little wind acanthus leafs with the 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 a 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 invention has the beneficial effects as follows:
Wind generating unit of the present invention through the setting of barge board, has avoided wind to blow to the phenomenon that symmetrical two little wind acanthus leafs cause wind-force to offset simultaneously, has improved the generating efficiency of perpendicular axis type wind-driven generator.And above-mentioned barge board can take off when wind-force is big, reduces the fan blade rotating speed, whole device has been played the effect of protection.

Embodiment
Below in conjunction with accompanying drawing and embodiment the specific embodiment of the invention is described:
Fig. 1,2 shows the structure of one embodiment of the invention, and is as shown in the figure, among the present invention; Support post 1 is the hollow cylinder body structure; Three support posts 1 are fixedly mounted on ground, and generator support 4 is made up 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, and blade shaft 5 passes this bearing and extends to fan blade base plate 9 belows, is connected through coupling at the rotor shaft of blade shaft 5 and generator 32.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 that the center is divided into four little wind acanthus leafs with 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 a quadrant annular shape, and barge board 8 is installed in the edge of fan blade base plate 9, is 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.
Above-mentioned wind generating unit; As shown in Figure 2, the arrow direction is represented wind direction, when wind comes; Because the effect of barge board 8 is arranged; Wind only blows to the little wind acanthus leaf that does not have barge board 8 one sides, drives wind acanthus leaf along a direction stable operation, can not occur that wind blows symmetrical two wind acanthus leafs simultaneously and the phenomenon that causes wind-force to cancel each other.Improve the utilization ratio of wind, increased generating efficiency.
Aforesaid wind generating unit, when making wind-force big, whole system is in the running state than the self-protection of low-rotate speed; Above-mentioned barge board 8 is a reassembling type arbitrarily, that is, barge board 8 can be by freely taking off or load onto on the fan blade base plate 9; When taking off, wind blows symmetrical wind acanthus leaf simultaneously, causes wind-force to offset; Whole fan blade does not rotate or to rotate than low rate, whole device has been played protective action.
