Abstract
The utility model relates to a double-rotor wind generator, which is composed of an inner rotor 1, an outer rotor 2, a fixed axle 3 and a wind blade 4, wherein the inner rotor and the outer rotor are respectively arranged on the fixed axle. A multi-stage winding 1-1 of the inner rotor is arranged on the outer side of a supporting bracket of the inner rotor and a permanent-magnetic ring 2-1 of the outer rotor is arranged on the inner side of a supporting bracket of the outer rotor. The supporting brackets of the inner rotor and the outer rotor are respectively provided with wind blades 4-1, 4-2. The fixed axle is composed of two parts, one part is a solid axle and the other part is composed of an axle core 3-1, an outer sleeve 3-2 of the axle core and an insulating layer arranged between the axle core 3-1 and the outer sleeve 3-2 of the axle core for separation. The output end of a tap of the multi-stage winding is respectively communicated with a bearing 6, a solid axle and the outer sleeve of the axle core to output voltage positive and negative poles. Because the inner rotor and the outer rotor of the double-rotor wind generator simultaneously and mutually rotate in an opposite direction, the speed of the winding cutting magnetic lines is increased by one time. Thus, the electricity quantity generated by the generator is also increased by one time.
Description
Technical field
The utility model belongs to technical field of generators, exactly is a kind of portable dual-rotor wind power generation machine.
Background technique
At present, the wind-driven generator of every field extensive use, its rotor and stator opposite shell, stator is non-rotary, has only rotor in rotation, is a kind of wind-driven generator of single rotor, so the relative rotation speed of rotor and stator is limited, these all belong to traditional wind-driven generator.And traditional wind has only a grade blade, and blade connects rotor in rotation, and stator is non-rotary.Traditional wind since its structural design on restriction, do not make full use of wind energy, so the rotating speed of the generator amature that works together is on the low side, then output power, be that generated energy is also on the low side.
The model utility content
The purpose of this utility model is in order to overcome deficiency of the prior art, traditional wind to be carried out bigger improvement from structure, under same wind-force, compares with traditional wind, and its generated energy is doubled.
The utility model is to realize with following technical proposal: this dual-rotor wind power generation machine, it is made up of the stationary axle and the two-stage fan blade of internal rotor, external rotor, inner and outer rotors.Wherein internal rotor is to be made of multistage winding and carriage thereof, and multistage winding places the outside of carriage; External rotor is to be made of permanent-magnetic clamp and carriage thereof, and permanent-magnetic clamp places the inboard of carriage.Be respectively equipped with 2-6 sheet one-level fan blade, secondary fan blade on the carriage of inner and outer rotors, described stationary axle places on the pedestal.Stationary axle is made of two-part, and a part is a solid shaft, and another part is axle core and axle core overcoat, is provided with isolation layer between axle core and axle core overcoat, is provided with dead ring between axle core overcoat and the solid shaft and constitutes; Also can be that a complete solid shaft constitutes.Described inside and outside rotor places on the stationary axle by bearing respectively.By stationary axle output voltage both positive and negative polarity.
The utility model is compared with traditional single rotor, single-stage fan blade generator, and under weight, external dimension, the essentially identical situation of cost of production, its rotating speed is doubled, and generator power is doubled.Through the utility model (1000W generator) is carried out site test this point has been described: experiment one is that this generator external rotor is fixed, and under constant wind-force effect, has only the internal rotor rotation, and at this moment, the rated output power of generator is 500W; Experiment two is to allow external rotor and internal rotor rotate simultaneously, or same wind-force, and its rated output power is 1000W as a result.Evidence: the generator that inner and outer rotors rotates simultaneously, its output power will exceed more than one times than the output power of single rotor generator.
Description of drawings
Fig. 1 is the whole external and internal compositions connection diagram of the utility model.
Embodiment
In conjunction with the accompanying drawings external link structure and working principle in the integral body of the present utility model are specified: shown in Figure 1, described dual-rotor wind power generation machine is by internal rotor 1, external rotor 2, and inner and outer rotors stationary axle 3 and fan blade 4 are formed.Wherein internal rotor and external rotor are installed on the stationary axle 3 by bearing 6 respectively.Described internal rotor is made of multistage winding 1-1 and carriage 1-2 thereof; External rotor is made of magnetic rings 2-1 and carriage 2-2 thereof.Wherein magnetic rings 2-1 is embedded in the inboard of carriage 2-2, and multistage winding 1-1 is embedded in the outside of carriage 1-2, promptly between carriage 1-2 and the magnetic rings 2-1.The periphery device of carriage 1-2 has three fan blade 4-1, and the periphery of carriage 2-2 also device has three fan blade 4-2.Said stationary axle 3 is to be made of two-part, and a part is solid shaft part, and another part is provided with isolation layer by axle core 3-1 and axle core overcoat 3-2 between axle core and axle core overcoat, be provided with dead ring 3-3 between axle core overcoat and the solid shaft and constitute.Tap output terminal on the multistage winding is communicated with the output voltage both positive and negative polarity by bearing 6 with solid shaft, axle core overcoat respectively.Stationary axle 3 is installed on the pedestal 5.
The working principle of dual-rotor wind power generation machine: when working under the one-level fan blade of generator and of the effect of secondary fan blade, external rotor is turned clockwise, produce a magnetic field that turns clockwise at wind-force; Internal rotor is done and is rotated counterclockwise simultaneously, makes coil winding cut the magnetic line of force of external rotor rotating magnetic field relatively, and induce electromotive force on winding, and with this electromotive force output, electric energy produces thus by lighting outlet.Because inside and outside rotor is rotated simultaneously and mutually in the other direction, makes the speed of coil winding cutting magnetic line be doubled, so the electric power that produces also is doubled.
