Description
Technical field
The utility model belongs to technical field of generators, particularly a kind of wind-driven generator.
Background technique
Along with the development of MEMS, low power consumption and super low-power consumption electronic device product progressively obtain popularization, as the microsensor in wireless sensor network and the microdrive etc. in precision type instrument.Meanwhile, based on MEMS low power consumption characteristic, in the research field of micro electromechanical equipment, the research of self-power supply system becomes inevitable trend.Piezoelectric constant has the characteristic of data-collection, utilizes its direct piezoelectric effect that the mechanical vibrational energy in environment is converted into electric energy.Wind energy belongs to reproducible clean energy resource, has inexhaustible advantage, utilizes the wind energy in environment as the vibration source of piezoelectric device, piezoelectric constant can be encouraged to produce distortion, thus realize the conversion of mechanical energy to electric energy.
Wind generating unit before also not using piezoelectric constant as producing the material of electric energy, so also not by design that wind mill equipment combines with piezoelectric generating device.
Because MEMS application area is extensive especially, there is a lot of dispersion, unsociable and eccentric or be in the Micro Energy Lose electronic parts and components of dangerous situation, the energy that these Micro Energy Lose components and parts need is not high, but provides power very difficult to these Micro Energy Lose electronic parts and components, the manpower and materials of at substantial.This does not meet the modernization development trend of environmental protection and unmanned management yet.
Model utility content
Problem to be solved in the utility model is to provide a kind of piezoelectric constant wind-driven generator, can realize the self energizing of Micro Energy Lose electronic parts and components, solves the energy supply problem of Micro Energy Lose electronic parts and components.
Piezoelectric constant wind-driven generator disclosed in the utility model, is characterized in that: comprise base plate, the support that fixed installation two is relative on described base plate and some cantilever beam piezoelectric vibrators, and cantilever beam piezoelectric vibrators one end is all fixed on fixing rod; Install bent axle between two supports, windmill is arranged on bent axle one end, and one end of connecting rod is connected with bent axle, and the other end is enclosed within fixing rod.
As the further improvement of technique scheme, described windmill fixedly mounts air blade.
As the further improvement of technique scheme, be set with bearing at described crankshaft two end and fix bent axle 5.
Improving further again as technique scheme, that one end that described cantilever beam piezoelectric vibrators is fixed on fixing rod has hole, to be more firmly fixed on fixing rod.
Piezoelectric constant wind-driven generator of the present utility model has following beneficial effect:
1, wind energy common for occurring in nature can be combined with vibrational energy by this device effectively, and multiple piezoelectric vibrator can be forced to deform simultaneously, substantially increases piezo-electric generating efficiency, overcomes the shortcoming that piezo-electric generating amount is little.

3, this device can effectively for those dispersions of field, unsociable and eccentric Micro Energy Lose electronic parts and components provide electric energy, have structure simple, be easy to the many merits such as processing, cost is low, conversion ratio is high, environmental protection.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the piezoelectric constant wind-driven generator that the utility model proposes is described in detail.
As shown in Figure 1, piezoelectric constant wind-driven generator of the present utility model, comprises base plate 1, the support 7 that fixed installation two is relative on described base plate 1 and some cantilever beam piezoelectric vibrators 2.All cantilever beam piezoelectric vibrators 2 one end perforates, and be all fixed on fixing rod 3.Between two supports 7, install bent axle 5, bent axle 5 two ends are set with bearing 8, and bearing 8 is placed in the mounting hole on support 7, locates bent axle 5 by bearing 8.The windmill 6 being installed with air blade is arranged on bent axle 5 one end.One end of connecting rod 4 is connected with bent axle 5, and the other end is enclosed within fixing rod 3, and fixing rod 3 can rotate in this end of connecting rod 4.
Piezoelectric constant wind-driven generator working principle of the present utility model: from electromagnetic coupling generator, wind energy is converted into mechanical energy and drives generator to rotate to produce the different of electric energy, piezoelectric constant wind-driven generator of the present utility model provides one to force displacement to make it deform mainly to the free end of cantilever beam piezoelectric vibrators, thus produces electric charge on piezoelectric constant surface.To the conversion of this kind of energy, adopt the energy transferring mode of " bent axle-connecting rod ".The rotating band dynamic crankshaft of air blade rotates.Connecting rod is under the effect of bent axle, and rotation motion is done in one end, and the other end does reciprocal circular motion, reciprocal circular motion can make fixing rod seesaw, the motion of fixing rod drives cantilever beam piezoelectric vibrators group to seesaw, thus reaches the object that piezoelectric constant deforms, and finally produces electric energy.
