Specific embodiment
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 description, 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.
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
It and more than third layer is collection stratification of wind；First layer can be used for being arranged between equipment room, maintenance, spare unit library etc., and top can between maintenance
Hoisting mechanism is set；The second layer can be used for being arranged control room and lobby etc..By using tower structure, electricity generation system can be reduced
Occupied area can reduce cost compared with conventional photovoltaic, wind power station.
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 each vertical seat of air guiding wall 102 is set to the laminate of the corresponding collection stratification of wind
On 101, and extend 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. one layer of laminate 101 on the collection stratification of wind) 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 the gap between every layer of each air guiding wall 102 and corresponding wind power generation unit 4 is 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, conducive to the rotation of wind power generation unit 4
Turn acting；In the present embodiment, to guarantee that wind has sufficient free air space, the width control in above-mentioned distinguished and admirable road 5 is being 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
It can be improved wind speed 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 of the wind across tower body 1 bigger, 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, and electrical-coil is suspended in certain sky by the magnetic force of combining super magnet
Between, in the case where no any mechanical friction, by the rotation of Wind power propelling motor and cutting magnetic line issues alternating current, and stores up
It is stored in battery.For conventional flat axle type wind driven generator, the advantage is that:
First, by the wind, threshold wind velocity is lower for multi-panel；Conventional flat axle type wind driven generator has 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, indefinite wind direction bring can not be overcome to shake, motor, leaf
Piece is easy to fall off, 3 years must accessory of replacement；And the operating of vertical shaft maglev wind power generator 4 is stablized, noiseless, various machines
The part service life is long, not easily to fall off, can be 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
Generator 4 is low to space requirement；
4th, the power generation wind speed of vertical shaft maglev wind power generator 4 is lower.Conventional flat axle type wind driven generator starts wind
Speed at least 2.5m/s, and vertical shaft maglev wind power generator 4 only needs 1m/s wind speed that can start, wind speed is more than 40m/s can also
As usual it operates, and wind speed more high generation efficiency is higher, generated energy increases by 35% than the former.
5th, vertical shaft maglev wind power generator 4 uses optimal energy allocation technology, is risen in low wind speeds
Pressure, makes blower that can charge to battery when compared with the slow-speed of revolution；Output power is limited when high wind speed, in order to avoid damage battery.
In the present embodiment, preferably the vertical shaft maglev wind power generator 4 in each collection stratification of wind is disposed as modular
