Accompanying drawing explanation
Fig. 1 is the structural representation of staged piezoelectric generator.
Embodiment
Below in conjunction with concrete accompanying drawing, further illustrate the utility model, this embodiment is implemented take technical solutions of the utility model under prerequisite, should understand these modes and only for the utility model is described, be not used in restriction scope of the present utility model.
As shown in Figure 1, staged piezoelectric generator, main structural components comprises the first end cap 1, the second end cap 2, cylindrical shell 3, axle 4, axle pedestal 5, ladder fixedly piezoelectric bimorph pedestal 6, rotation ladder cam 7, piezoelectric bimorph 8 and lead-in wire 9.The first end cap 1 and the second end cap 2 are located at respectively the two ends of cylindrical shell 3 correspondences, are together to form generator body; At generator body inner bottom part, establish axle pedestal 5, axle 4 one end are connected with axle pedestal 5 by a bearing, and the other end, is connected with outside power mechanism (utilizing elemental impeller, Mechanical Driven etc.) through the second end cap 2 by another bearing; On axle 4, establish rotation ladder cam 7, in generator body, establish fixedly piezoelectric bimorph pedestal 6 of ladder, at the fixing piezoelectric bimorph pedestal 6 and rotate between ladder cam 7 and establish a plurality of piezoelectric bimorphs 8 of ladder; In one end of piezoelectric bimorph 8, establish lead-in wire 9, for being connected with rectification circuit.Piezoelectric bimorph 8 one end and ladder fixedly piezoelectric bimorph pedestal 6 are connected, the other end is that the free end of piezoelectric bimorph 8 contacts with rotation ladder cam 7, by the rotation of rotation ladder cam, realize and stir piezoelectric bimorph, make the generating of piezoelectric bimorph bending tablet.Wherein, piezoelectric bimorph is pressed stepped construction and is arranged, and every group is no less than 2 layers.
In order to guarantee the efficiency operation of Changshou life, except adopting high performance piezoelectric ceramic, also can be by two ceramic bondings on composite material (this composite material can be carbon fiber), make pottery and composite material one each other after bonding, become piezoelectric bimorph 8.So both can increase the intensity of potsherd, and make piezoelectric ceramic not easily broken, improve again the piezoelectric ceramic power generating device life-span.
Adopt stepped construction mainly to consider, under same volume, can improve energy output.Rotation ladder cam staged piezoelectric generator and ladder fixedly piezoelectric bimorph are corresponding one by one, the every rotation of rotation ladder cam one week, and each organizes piezoelectric ceramic power generating device, all can produce electric charge by stress deformation.
Natural force promotes staged piezo-electric generating arbor by wind-force or current and rotates, and then stirs the generating of piezoelectric ceramic power generating device.Also can rotate by rotating machinery, by driven pulley band moving axis on staged piezo-electric generating arbor, pass on the object of generating.
