Embodiment
With reference to Fig. 1~Fig. 6, the utility model is a kind of wind-force disturbance formula piezoelectric generator, comprises a fixed pivot axis 1 and is fixedly installed in a fixed pivot axis 1 a slice or multi-disc fan blade 2 all around, all is covered with piezoelectric element 3 on a side of each fan blade 2 or two sides.
The piezoelectric generator of this wind-force disturbance formula has been installed multi-disc fan blade 2 on an a fixed pivot axis 1; Disturbance through fan blade 2 under wind makes that being covered on the fan blade 2 piezoelectric element on one or two sides 3 produces piezoelectric effects and generate electricity; This piezoelectric generator can generate electricity when the gentle breeze disturbance; Help realizing effective utilization, save the cost that adopts wind-power electricity generation simultaneously wind energy.
Improvement as the utility model technological scheme; Be installed with some minutes poles 4 around a fixed pivot axis 1; End away from a fixed pivot axis 1 on each minute pole 4 is equipped with fan blade installation shaft 5, all is installed with a slice or multi-disc fan blade 2 around each fan blade installation shaft 5.
The piezoelectric generator of this wind-force disturbance formula can have multiple way of realization to the installation of fan blade 2; Around a fixed pivot axis 1, a plurality of minutes poles 4 are installed, and can continue on minute pole 4, to set up more minute pole 4, in the scope that can bear; Fan blade 2 as much as possible is installed; Thereby more piezoelectric element 3 can be installed, also reach interior among a small circle bigger generator, reach the utilization ratio bigger wind energy.
This piezoelectric generator piezoelectric element 3 in power generation process does not have the vibration of macroscopic view; And only under the fan blade agitation, carry out the vibration of high frequency microcosmic; Any installation way of realization of fan blade 2; Only need satisfy piezoelectric element 3 and under the wind-force disturbance, carry out the high frequency microscopic vibration and generate electricity, then all in protection scope of the present invention.
As the improvement of the utility model technological scheme, fan blade 2 is rectangle with piezoelectric element 3, and the length of fan blade 2 and width are not less than the length and the width of piezoelectric element 3 respectively.
As the improvement of the utility model technological scheme, fan blade 2 is oval or arbitrary plane figure, and piezoelectric element 3 full wafers all paste on a side or bi-side of fan blade 2.
As the improvement of the utility model technological scheme, fan blade 2 comprises that the piezoelectric element that is used to paste piezoelectric element 3 pastes district 21 and the disturbance enhancement region 22 that strengthens fan blade 2 disturbances.
As the improvement of the utility model technological scheme, disturbance enhancement region 22 and piezoelectric element paste district 21 and are coupled to each other into an integral body, and disturbance enhancement region 22 and piezoelectric element paste district 21 and be respectively through number of various materials and form.
Fan blade 2 on the wind-driven generator of this disturbance formula also can be by multiple way of realization; The integral body that only needs to guarantee piezoelectric element 3 all pastes on fan blade 2; Thereby the part that exceeds piezoelectric element 3 is arranged on the fan blade 2, can play frequency reducing and the effect that increases disturbing force the vibration of piezoelectric element 3.
