The device comprises a vibrating plate which can absorb the noise sound wave and vibration wave, wherein a piezoelectric ceramic chip which is connected on a basic supporting frame is vertically arranged near the vibrating plate, one side of the vibrating plate is connected with the piezoelectric ceramic chip through a drive rod which points at the piezoelectric ceramic chip, and the piezoelectric ceramic chip is connected with a steel ball through a spring. The device not only can utilize noise or vibration to carry out self power generation, saves energy and protects the environment, but also has simple structure.
Description
Technical field
The utility model relates to the application in new energy development and environmental protection field of physics and electronic technology, particularly a kind of device that utilizes noise sound wave or vibration energy to carry out self power generation.
Background technology
On the highway of ground or bridge floor, particularly at some traffic intersections, when motor vehicle by or meet red light etc. and bide one's time, the vibration meeting that engine operation drives vehicle body forms strong vibrations to ground, particularly at vehicle flowrate too big or wagon flow is smooth, during the jogging of motor vehicle idling, this vibrations will be more obvious.Also will inevitably produce a lot of noises in these processes, this has caused very serious noise pollution to environment on every side.If can be used to these vibrations or noise acoustic wave energy, as being converted to electric energy and storing, use or supply with the cell phone charging station at crossing with the traffic lights of supplying with the crossing, is very useful for the development that promotes whole society's energy-conserving and environment-protective cause.
Summary of the invention
The purpose of this utility model provides a kind of piezoelectric type noise vibration self-generating device, and this device not only can utilize noise or vibrations to carry out self power generation, energy-conserving and environment-protective, and also simple in structure.
The purpose of this utility model is achieved in that this piezoelectric type noise vibration self-generating device, comprise the vibrating reed that can absorb noise sound wave or vibration wave, the perpendicular piezoelectric ceramic piece that is connected on the base rack that is provided with of described vibrating reed side, the drive link that piezoelectric ceramic piece is pointed in described vibrating reed one side one is connected with piezoelectric ceramic piece, is connected with a steel ball through a spring on the described piezoelectric ceramic piece.
Distinguishing feature of the present utility model is the structural design by integral body, the billboard at roadside or crossing is combined with the noise vibration energy collecting device, utilize billboard to increase the noise receiving area, to improve energy conversion efficiency, so both can generate electricity, as the cell phone charging station of supplying with the traffic lights at crossing or crossing uses, can effectively reduce the influence of motor vehicle noise to surrounding enviroment, energy-saving and emission-reduction, environmental protection again.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment monomer.
Fig. 2 is the view that is used in combination of the utility model embodiment.
Embodiment
Piezoelectric type noise vibration self-generating device of the present utility model, comprise the vibrating reed 1 that can absorb noise sound wave or vibration wave, the perpendicular piezoelectric ceramic piece 3 that is connected on the base rack 2 that is provided with of described vibrating reed 1 side, the drive link 4 that piezoelectric ceramic piece 3 is pointed in described vibrating reed 1 one sides one is connected with piezoelectric ceramic piece 3, is connected with a steel ball 6 through a spring 5 on the described piezoelectric ceramic piece 3.
Above-mentioned vibrating reed 1 is the billboard at roadside or crossing, to increase the noise receiving area, to improve energy conversion efficiency.
In order to absorb the energy of noise substantially, be horizontally set with several horizontal supports 7 on the above-mentioned base rack 2 from top to bottom, be connected with piezoelectric ceramic piece 3 lower ends respectively on described each horizontal support 7.
During application, adopt highway side or traffic intersection billboard as vibrating reed 1, the noise sound wave that advertising sign face receiver motor-car produces, the noise sound wave causes that advertising sign face produces vibration, by drive link 4, vibration is transmitted on the piezoelectric ceramic piece 3, and mechanical deformation takes place piezoelectric ceramic piece 3, utilize the direct piezoelectric effect of piezoelectric ceramic, thereby produce alternating voltage output.
Several piezoelectric type noise vibration self-generating device combination of monomers are lined up an array, place the back of billboard, billboard is connected with piezoelectric ceramic piece 3 through drive link, some the sound waves that the motor car engine noise sends, form different corrugateds, promote different point on the billboard, give each piezoelectric ceramic piece 3 in the array by drive link 4 with its energy delivery, make piezoelectric ceramic piece 3 that mechanical deformation take place, produce voltage output thus, several piezoelectric type noise vibration self-generating device monomers are formed array, and the energy of output superposes, and just can increase the gross energy of collection.
Be arranged at the steel ball 6 on the piezoelectric ceramic piece 3, can utilize the vibrations of motor vehicle simultaneously, promotion piezoelectric ceramic vibration, it is stressed when crooked to have a certain thickness piezoelectric ceramic, is elongation in the one side, opposite side is compression, inside, piezoelectric ceramic piece 3 both sides will produce the different electric charges of symbol this moment, and upper and lower surface tape symbol opposite charges is when the phase place of vibration signal changes, therefore the electric charge sign inversion of piezoelectric ceramic piece 3 both sides can obtain alternating voltage output.
