Technical problem to be solved in the utility model is at above the deficiencies in the prior art, provide that a kind of simulation wind-power electricity generation is effective, security performance is high, can as the teachers ' teaching demonstration with the simulation aerogenerator demonstrator that can allow the student start personally again to put into practice.
For addressing the above problem, the utility model provides a kind of simulation aerogenerator demonstrator, comprise generator, the light emitting diode that is connected with first fan blade, the motor that is connected with second fan blade, box body, be linked to be the closed-loop path with lead between generator and the light emitting diode, the motor two ends are connected with low-voltage dc power supply with lead, first fan blade and second fan blade are oppositely arranged, and generator, light emitting diode and motor are fixed on the box body.
After adopting above structure, the utility model compared with prior art, have the following advantages: the utility model simulation aerogenerator demonstrator comprises generator, the light emitting diode that is connected with first fan blade, the motor that is connected with second fan blade, box body, generator, light emitting diode and motor are fixed on the box body, so whole simulation aerogenerator demonstrator is as a whole, is convenient to move; And this simulation aerogenerator demonstrator adopts low-voltage dc power supply to expedite the emergence of wind-power electricity generation, the security performance height, thus can not only be as the usefulness of teachers ' teaching demonstration, also can allow student's hands-on practice, deepen the impression of imparting knowledge to students.Because first fan blade of this simulation aerogenerator demonstrator and be oppositely arranged with second fan blade, position relative fixed and spacing are suitable, thus with this simulation aerogenerator demonstrator simulate wind-power electricity generation success ratio height, to simulate wind-power electricity generation effective.Be connected with generator, the light emitting diode of first fan blade, the parts such as motor that are connected with second fan blade be positioned at intuitively can observable box body on, this makes the effect of simulation wind-power electricity generation directly perceived, the student understands easily.
Described generator, light emitting diode and motor are positioned at cartridge upper surface.Critical pieces such as generator, light emitting diode, motor are arranged on the same box body surface, make experiment effect directly perceived, the student understands easily.
Described low-voltage dc power supply adopts the form of external power interface configuration power supply adaptor, is connected with power switch with lead in the circuit that motor and external power interface are linked to be, and external power interface and power switch are fixed in cartridge upper surface.The external power interface is used to connect power supply adaptor, power supply adaptor is a 4.5V 6V direct supply, power switch is used to control the Push And Release of the circuit that motor and external power interface is linked to be, after power supply adaptor connected, control the rotation of the fan that is connected with motor, safer and power saving with power switch.
Described light emitting diode two ends are connected with voltage table with lead, and voltage table is fixed in cartridge upper surface.Voltage table is used to test the light emitting diode two ends no-voltage existence, makes the wind-power electricity generation effect more directly perceived.
Described lead is installed on box body inside, and cartridge upper surface is decorated with the line that the expression lead connects.Lead is installed on box body inside, makes surface ratio, and can not touch lead in the experimentation, avoided lead is damaged than neatly and orderly; And with the method for setting-out lead is marked at cartridge upper surface, make the structure of whole simulation aerogenerator demonstrator more directly perceived, be easy to the student and understand.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
As shown in Figure 1 and Figure 2, the utility model simulation aerogenerator demonstrator comprises generator 2, the light emitting diode 3 that is connected with first fan blade 1, the motor 5 that is connected with second fan blade 4, box body 6.
First fan blade 1 and second fan blade 4 are oppositely arranged, and first fan blade 1 and second fan blade, 4 stationkeeping and spacing are suitable, so one of them fan blade rotates, just can drive the another one fan blade and also rotate.
The circuit diagram of this simulation aerogenerator demonstrator as shown in Figure 3.
The process of simulating wind-power electricity generation with this simulation aerogenerator demonstrator is: power supply adaptor is connected in external power interface 7, controlling power switch 8 then makes motor 5 place circuits be closure state, motor 5 will drive second fan blade 4 and rotates like this, second fan blade 4 rotates drive first fan blade 1 and also rotates, the wind energy that generator 2 utilizes first fan blade 1 to rotate is carried out wind-power electricity generation, generating makes light emitting diode 3 lamps of generator 2 place circuits bright, and the voltage table 9 at light emitting diode 3 two ends has reading to show, this explanation light emitting diode 3 has electric current to pass through, and there is voltage in light emitting diode 3 two ends.
For the effect that makes experiment more directly perceived, the student is more readily understood, also can between first fan blade 1 and second fan blade 4, assign a deep bead, when such second fan blade 4 rotates, first fan blade 1 can not rotate owing to being blocked just by deep bead, this time, light emitting diode 3 lamp did not work, and voltage table 9 does not have reading to show yet.Then deep bead is taken out, second fan blade 4 just drives first fan blade 1 and rotates, and this time, light emitting diode 3 lamp brightened, and voltage table 9 also has reading to show, this explanation is that the rotation of first fan blade 1 has caused the circuit at light emitting diode 3 places to have electric current to exist, and is the result of wind-power electricity generation.
Above embodiment is to explanation of the present utility model and further explains, rather than to restriction of the present utility model, any modification of being done in interest field of the present utility model all falls into protection domain of the present utility model.
