Technical field
The utility model relates to a kind of energy collecting device, the piezoelectric energy gathering-device of the utilization vibrations harvest energy that is particularly useful for using on the mini-plant.
Background technology
Sensor network technique has in productive life widely and uses as a kind of emerging monitoring technology.For sensor network, radio sensing network especially, the energy supply is very big to its influence, generally adopts powered battery.Yet wireless sensor network node is owing to the monitoring location reason in the engineering, and the replacing of battery is very difficult sometimes, and the useful life of battery is limited.Therefore, in order to realize the permanently effective work of whole sensor network, the prolonging wireless sensor network application life with reduce cost, be that at first demand side is right for wireless sensor network provides enough, long-term energy.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, can convert the mechanical vibrational energy in the environment into electric energy.
For achieving the above object, the piezoelectric energy gathering-device of the utility model comprises housing, comprises housing; Housing is provided with a plurality of wire guides, is provided with mass in the housing, and the upper and lower side of mass is fixed with spring respectively; The other end and the housing roof and floor of spring of linking to each other with mass fixes; The both sides of spring are equipped with the opposite piezoelectric ceramic piece of polarised direction, all are welded with the lead that passes wire guide on the every piezoelectric ceramic piece, and lead leads to outside through the wire guide on the housing.
Described mass is 1～3; Described spring is a conductive metallic material
Beneficial effect: the utility model comprises spring and piezoelectric ceramic piece, under stress, produces electric charge, realizes the conversion of mechanical energy and electric energy; Because the camber of spring ability is stronger; The piezoelectric ceramic piece deformability that is fixed in one with spring increases, and is simple in structure, can effectively promote its generating capacity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-piezoelectric ceramic piece, 2-spring, 3-wire guide, 4-mass, 5-housing, 6-lead.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe:
As shown in Figure 1, the piezoelectric energy gathering-device of the utility model comprises piezoelectric ceramic piece 1, spring 2, wire guide 3, mass 4, housing 5 and lead 6 compositions.Be provided with a mass 4 in the housing 5; As required, mass 4 can be 2 or 3, and mass 4 upper and lower sides are connected with spring 2; Fix at the bottom of the top of the other end of spring 2 and housing 5; The both sides of spring 2 are equipped with piezoelectric ceramic piece 1, all are welded with lead 6 on the every piezoelectric ceramic piece 1, and lead 6 leads to housing 5 outsides through the wire guide on the housing 53.Spring 2 one ends and housing 5 hinged securement, the other end and mass 4 hinged securement.Housing 5 left and right sides have wire guide 3.Lead 6 one ends are welded on the piezoelectric ceramic piece 1, lead to housing 5 outsides through wire guide 3.Spring 2 adopts the beryllium-bronze material to process, and piezoelectric ceramic piece 1 adopts PZT-5H or other piezoelectrics.Piezoelectric ceramic piece 1 needs longitudinal polarization, and the polarised direction of the piezoelectric ceramic piece 1 of spring 2 left and right sides is opposite when bonding.
The course of work: during the work of piezoelectric energy gathering-device, housing 5 is fixed on the work mechanism, the vibration of operational environment makes whole device follow vibration; Because the motion of mass 4; Spring 2 is followed vibration, and piezoelectric ceramic piece 1 produces tension and compression deformation, surface aggregation electric charge; Produce electromotive force, realize the conversion of energy.Any time, the piezoelectric ceramic piece 1 of mass 4 upper ends was in the opposite direction with the piezoelectric ceramic piece 1 tension and compression deformation of mass 4 lower ends, was the differential type electrification structure.
