Abstract
The utility model provides a wind-driven power generator, which comprises an upper inner blade, outer blades, a magnetic suspension power generator, a lower inner blade, a fan fixing seat and an outer blade fixing frame. The upper inner blade is arranged on the upper side of the outer blade fixing frame, the lower inner blade is arranged on the lower side of the outer blade fixing frame, the lower side of the lower inner blade is provided with the fan fixing seat, the magnetic suspension power generator is arranged between the upper inner blade and the lower inner blade, and the outer blades are connected with the outer blade fixing frame. Since the blades of the wind-driven power generator comprise the outer blades and the inner blades and the outer blades are arranged in the middle of the wind-driven power generator on the outer blade fixing frame between the two inner blades, the magnetic suspension power generator can be well driven for power generation. Since the magnetic suspension power generator is arranged in the middle, the wind on the blades of the whole wind-driven power generator can become more uniform, the balance of the wind-driven power generator can be more stabilized, the output power of the wind-driven power generator can be improved more effectively, and the service life of the wind-driven power generator can be further prolonged.
Description
Technical field
The utility model relates to a kind of wind-driven generator, belongs to technical field of wind power generation.
Background technique
The wind energy clean environment firendly belongs to renewable energy sources.People utilize the with a long history of wind energy, are used for generating at present more, but the natural wind force size and Orientation is changing at any time; Existing wind-driven generator its to start needed wind speed bigger; Minimum is 2m/S, but local mostly for China, does not many times reach such wind speed; The slatterning in vain so that the wind energy of low speed can not be utilized; How people make the wind of low speed start wind-driven generator in research, use so that be fit to the place of low wind speed, or let its life of generator prolong more.
In the existing wind-driven generator; Impeller generally places a side of generator, makes generator receive the downward action of gravity of impeller and bearing is produced non axial active force, makes shaft strength unbalanced; Adding that rotating shaft self has weight; Therefore produce bigger frictional force, and cause need be very big wind-force could starter-generator, wind-driven generator has overcome the resistance of its inner each position friction at work and the power of output has also been reduced greatly.
Summary of the invention
The purpose of the utility model is for solving in the existing wind-driven generator; Impeller generally places a side of generator, makes generator receive the downward action of gravity of impeller and bearing is produced non axial active force, makes shaft strength unbalanced; Adding that rotating shaft self has weight; Therefore produce bigger frictional force, and cause the problem of wind-force ability starter-generator that need be very big, and then a kind of wind-driven generator is provided.
The purpose of the utility model realizes through following technological scheme:
The utility model comprises: fan blade, external wind wheel, magnetic suspension generator, down interior fan blade, blower fan fixed base and external wind wheel fixing frame in going up; Fan blade is arranged on the upside of external wind wheel fixing frame in going up; Fan blade is arranged on the downside of external wind wheel fixing frame down; The downside of fan blade is provided with the blower fan fixed base down, and between fan blade and the down interior fan blade, external wind wheel was connected with the external wind wheel fixing frame in magnetic suspension generator was arranged on.
Can be found out by technique scheme: the fan blade of the utility model is made up of external wind wheel and interior fan blade two-part; External wind wheel is installed in the intermediate portion of wind-driven generator on the external wind wheel fixing frame in the middle of the fan blade in two groups, can better drives magnetic suspension generator and generate electricity.The interior air blade of the utility model is made up of up and down two groups of blades; Its magnetic suspension generator is installed in the intermediate portion of two groups of interior air blades up and down; Make its composition that is installed in series, just can let in the middle of being installed in the dynamics of blade of wind-driven generator wind-engaging of integral body more even magnetic suspension generator, make its balance can be more firm; Let wind-driven generator more effectively improve the output power of generator, the life-span of its wind-driven generator is prolonged more.Wind-force also can start less than 2m/S.
Description of drawings
Fig. 1 is the structural representation of the wind-driven generator that provides of the utility model mode of execution;
Fig. 2 is the component distribution schematic diagram of wind-driven generator.
Embodiment
To combine accompanying drawing that the utility model is done further detailed description below: present embodiment provided detailed mode of execution, but the protection domain of the utility model is not limited to following embodiment being to implement under the prerequisite with the utility model technological scheme.
As depicted in figs. 1 and 2; A kind of wind-driven generator that present embodiment is related; Comprise: fan blade 1, external wind wheel 2, magnetic suspension generator 3, down interior fan blade 4, blower fan fixed base 5 and external wind wheel fixing frame 6 in going up; Fan blade 1 is arranged on the upside of external wind wheel fixing frame 6 upward, and down interior fan blade 4 is arranged on the downside of external wind wheel fixing frame 6, and the downside of down interior fan blade 4 is provided with blower fan fixed base 5; Between fan blade 1 and the down interior fan blade 4, external wind wheel 2 was connected with external wind wheel fixing frame 6 in magnetic suspension generator 3 was arranged on.
Further, said external wind wheel 2 is formed by three, and three external wind wheels 2 are scalene and distribute, on one side wherein trigonometric form is the semicircle camber.
Concrete; External wind wheel 2 comprises two exogenous wind blade 2-1, two external wind wheel support 2-2 and two external wind wheel connecting sheet 2-3; Two external wind wheel connecting sheet 2-3 connect as one two exogenous wind blade 2-1, and two external wind wheel support 2-2 are fixedly connected two exogenous wind blade 2-1 respectively with external wind wheel fixing frame 6.
Said exogenous wind blade 2-1 is a hollow-core construction, and the material of said exogenous wind blade 2-1 is a light alloy.
The leg-of-mutton long air blade of being processed by light alloy of hollow inequality is processed the hollow more weight reduction of blade that just can make with the exogenous wind blade, reaches the optimum efficiency of load.Wind-driven generator exogenous wind blade is three optimum efficiencies that can realize the wind-driven generator wind-engaging.
Make the interior fan blade of generator be in up/down state; With the work that is together in series up and down of magnetic suspension generator and blade, and magnetic suspension generator is positioned over intra vane two groups centre up and down, is together in series; The gravity that just can overcome impeller and axle tilts; Just can make the equilibrant of this wind-driven generator obtain better effect, thereby reduce friction resistance, just can realize low wind speed starter-generator.
