Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
Embodiment one
Such as Fig. 1-Fig. 3, the embodiment of the present invention provides a kind of wind-light combined power generation system, including power generation column 1, the power generation column
1 tower body 1 is multilayer architecture, and at least partly tower layer is collection stratification of wind；In the present embodiment, such as Fig. 1,1 third layer of power generation column
And more than third layer it is collection stratification of wind；First layer can be used for being arranged equipment room, between repair, spare unit library etc., top can between repair
Hoisting mechanism is set；The second layer can be used for that control room and lobby etc. is arranged.By using tower structure, electricity generation system can be reduced
Floor space, more conventional photovoltaic, wind power station can reduce cost.
Such as Fig. 2, wind power generation unit 4 and multi-panel air guiding wall 102, the wind-power electricity generation list are equipped in each collection stratification of wind
Member 4 is set to the corresponding collection stratification of wind center, and 102 vertical seat of each air guiding wall is set to the laminate of the corresponding collection stratification of wind
On 101, and extended about from the adjacent wind power generation unit 4 to 101 outer rim of the laminate；In each collection stratification of wind, phase
Adjacent two air guiding walls 102, which enclose, to be set to form the air dam that an outside and inside are open, and each air dam is outer lateral from it
Its interior direction gradually tapers up.Wherein, each air guiding wall 102 is both preferably framework between adjacent two-ply 101, i.e., each wind-guiding
The top of wall 102 is connected with the top (i.e. the laminate 101 of the collection stratification of wind last layer) of corresponding collection stratification of wind, and one side wind effect is more
It is good, on the other hand play the role of supporting walls.It is each collection stratification of wind outer peripheral edge with 1 external space open communication of tower body, i.e., each collection
Stratification of wind is without side wall, to facilitate the collection of wind energy；To which the tower body 1 of third layer of the power generation column 1 or more is by corresponding each
Laminate 101 and corresponding each air guiding wall 102 build composition.Have one between each air guiding wall 102 and adjacent wind power generation unit 4
Fixed gap, and every layer of each air guiding wall 102 and the gap between corresponding wind power generation unit 4 are preferably identical, thus
A distinguished and admirable road 5 for being convenient for wind flow is formed between each air guiding wall 102 and wind power generation unit 4, is conducive to the rotation of wind power generation unit 4
Turn acting；In the present embodiment, for ensure wind have sufficient free air space, above-mentioned distinguished and admirable road 5 width control not less than
0.5m.In each collection stratification of wind, each air guiding wall 102 is radial to corresponding laminate 101 relative to corresponding wind power generation unit 4
Periphery extends；The outer openings of each air dam are formed as its distinguished and admirable entrance, the distinguished and admirable entrance and 1 external space open communication of tower body,
Inside outlet is formed as its distinguished and admirable outlet, and the distinguished and admirable outlet face wind power generation unit 4, wind enters air dam via distinguished and admirable entrance
It is interior, then enter in distinguished and admirable road 5 via distinguished and admirable outlet, driving wind power generation unit 4 does work, and is discharged via the air dam of the other side
Outside tower body 1.Since each air dam is in gradually-reducing shape, two air dams, which match, may make up a Venturi tube structure so that wind is collecting
Wind speed can be improved when wind intrastratal flow because of Venturi effect, and wind power generation unit 4 is located at corresponding Venturi tube structure
Aditus laryngis portion, thus generating efficiency can be effectively improved.Meanwhile entering the direction of tower body 1 corresponding to wind, wind can produce at 1 back side of tower body
Raw vortex, the presence of the vortex make the pressure drop bigger across the wind of tower body 1, and thus, it is possible to quickly improve wind power generation unit 4
Blade rotation.
In the present embodiment, above-mentioned wind power generation unit 4 preferably uses vertical shaft maglev wind power generator 4, vertical axis
Magnetic suspending wind turbine generator 4 uses magnetic levitation technology, the magnetic force of combining super magnet that electrical-coil is suspended in certain sky
Between, in the case of no any mechanical friction, alternating current is sent out by the rotation of Wind power propelling motor and cutting magnetic line, and store up
It is stored in battery.For conventional flat axle type wind driven generator, it the advantage is that：
First, by the wind, threshold wind velocity is lower for multi-panel；Conventional flat axle type wind driven generator carries empennage, it is necessary to box haul
Variation rotation windmill；Vertical shaft maglev wind power generator 4 is rotated by the gyroscope type wind wing, and not box haul variation changes axle center.
Second, conventional flat axle type wind driven generator noise is big, the shake that indefinite wind direction can not be overcome to bring, motor, leaf
Piece is easy to fall off, and must replace an accessory within 3 years；And the operating of vertical shaft maglev wind power generator 4 is stablized, noiseless, various machines
Part long lifespan, it is not easily to fall off, it can continuous work 20 years or more.
Third, conventional flat axle type wind driven generator require spacious unsheltered large space；And vertical shaft maglev wind-force
