Description
Technical field:
The invention belongs to vibration utilization, collection of energy, clean energy resource field.Relate in particular to a kind of generator that utilizes single pendulum and piezoelectric effect generating.
Background technology:
Extensively there is reproducible clean energy resource in the natural environment, like wind energy, solar energy etc.Along with the development of low power dissipation electron technology, utilize the generating of vibration recuperated energy to have potential using value.
Up to the present, the vibrational energy retracting device that utilizes vibration to generate electricity, promptly vibrating electricity generator is mainly based on three kinds of mechanism: electromagnetic induction, piezoelectric effect and electrostatic effect.The electric current that induction vibrating electricity generator produces is big and voltage is little, and piezoelectric effect formula voltage is big and electric current is little, and electrostatic voltage and current is all less.For piezoelectric generator, novel piezoelectric material and novel electricity generator structure all are to study focus at present.
Summary of the invention:
The purpose of this invention is to provide a kind of generator that utilizes single pendulum and piezoelectric effect generating.
A kind of mono-pendulum type piezoelectric generator is characterized in that: by pedestal, be connected in pedestal below the single pendulum parts, be installed on the cantilever beam piezoelectric part that evenly is arranged on the pedestal around the single pendulum parts and form; Above-mentioned single pendulum parts are made up of cycloid and pendulum; Above-mentioned each cantilever beam piezoelectric part is formed by cantilever beam and the piezoelectric patches that is attached on the cantilever beam.
Above-mentioned mono-pendulum type piezoelectric generator is characterized in that: the cross section of said base can be circular or polygon.
Single pendulum hangs on and connects the base bottom center.The cantilever beam that multi-disc is posted piezoelectric patches is around being installed in around the single pendulum.Cause the cantilever beam vibration when single pendulum knocks cantilever beam during at the dynamic excitation lower swing, the piezoelectric patches that is installed in simultaneously on the cantilever beam produces distortion, and produces electric charge on the positive and negative surface of piezoelectric patches.The piezoelectric patches both positive and negative polarity is connected with load with lead, and electric current, voltage and power that just can sensing lead be perhaps with the charge-trapping utilization.Owing to install around single pendulum when cantilever beam is installed, therefore when any direction is swung, can knock cantilever beam when single pendulum, thereby improve generating efficiency, and can be in occurring in nature use complicated and changeable.
The present invention innovates and has proposed a kind of novel electricity generator structure of utilizing single pendulum and piezoelectric effect generating; This electric generator structure is simple; Convenient use at natural environment complicated and changeable, the environmental energy that can collect various ways especially can be used for collecting low-frequency vibration energy.

Embodiment:
Be elaborated below in conjunction with the technical scheme of accompanying drawing to invention:
Generator among the present invention is by single pendulum, cantilever beam 3 array components, and piezoelectric patches 4 is formed with pedestal 5.The cantilever beam that posts piezoelectric patches 3 arrays are installed on the pedestal 5 around single pendulum.When single pendulum during at the dynamic excitation lower swing, pendulum knocks cantilever beam 3 and causes vibration, and the piezoelectric patches 4 that is installed in simultaneously on the cantilever beam produces distortion, and produces electric charges on piezoelectric patches 4 positive and negative surfaces, again through external circuitry with the charge-trapping utilization.
Embodiment one
In this instance pedestal 5 is designed to a hexa-prism, after sticking piezoelectric ceramic on the cantilever beam (3), is fixed in a wherein side of six prisms again, like Fig. 1.Single pendulum hangs on pedestal 5 bottom centre positions, and is parallel to cantilever beam, like Fig. 2.The cantilever beam that posts piezoelectric ceramic 3 symmetries are fixed on six prismatic six faces, form cantilever array.Fig. 3 is the schematic three dimensional views of enforcement one.Fig. 4 is the bottom view profile of embodiment one.When generator rocked under external influence, inner single pendulum swing pendulum will knock cantilever beam 3, thereby makes the piezoelectric ceramic distortion produce the electric charge generating.Because whole generating machine structural symmetry, when single pendulum can knock cantilever beam when any direction swing, thereby improved generating efficiency, and can be in changeable occurring in nature use.
