Description
Technical field
This utility model relates to a kind of energy device, a kind of collection of energy based on piezoelectric ceramics and utilize device.
Background technology
Piezoceramic material has " forward and reverse transformation electrical effect ", is i.e. produced electric energy when piezoceramic material by mechanical force impact immediate set.Piezo-electric generating is a kind of new free of contamination energy utilization patterns, and being currently based on the TRT of piezoelectric ceramics is that the direct piezoelectric effect utilizing piezoelectric ceramics, i.e. stress deform upon generation electric energy thus carry out collection of energy utilization, and therefore, piezoelectric ceramics is generating core.Cause deformation excessive if piezoelectric ceramics stress is excessive, can damage and ineffective, therefore particularly important to the protective measure of piezoelectric ceramics.Prior art is all to protect piezoelectric ceramics in terms of stress, reduces stress the most as far as possible or arranged buffer unit before piezoelectric ceramics is under pressure: by arranging the supporting construction of force rod and elastic parts；By installing buffer unit, reduce the stress etc. of piezoelectric ceramics.But these are all to reduce stress as far as possible, it is impossible to thoroughly avoid piezoelectric ceramics stress to cross large deformation excessive.
Utility model content
The purpose of this utility model is provide a kind of collection of energy based on piezoelectric ceramics and utilize device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of collection of energy based on piezoelectric ceramics and utilize device, including power generator, energy collection module and energy-storage travelling wave tube, power generator connects energy collection module, and energy collection module connects energy-storage travelling wave tube；Described power generator includes pressing plate, buffer stopper, piezoelectric ceramics, amortisseur and shell, pressing plate is connected with buffer stopper by amortisseur, buffer stopper and piezoelectric ceramics with the use of, piezoelectric ceramics uses built on stilts process to lay in the enclosure, for built on stilts part below piezoelectric ceramics, the height of built on stilts part is 3mm, and amortisseur is positioned at piezoelectric ceramics both sides.
As further program of the utility model: buffer stopper and amortisseur all use the material that shock resistance is good to make.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, easy to operate；The deformation quantity of piezoelectric ceramics is controlled within 3mm, it is to avoid piezoelectric ceramics causes damaging because of overstress, reduces fault rate, remove from and frequently changing and the trouble of maintenance, extend service life, reduce cost.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-3, a kind of collection of energy based on piezoelectric ceramics and utilize device, including power generator 8, energy collection module 9 and energy-storage travelling wave tube 10, power generator 8 connects energy collection module 9, and energy collection module 9 connects energy-storage travelling wave tube 10；Described power generator 8 includes pressing plate 1, buffer stopper 2, piezoelectric ceramics 3, amortisseur 4 and shell 5, pressing plate 1 is connected with buffer stopper 2 by amortisseur 4, buffer stopper 2 and piezoelectric ceramics 3 with the use of, piezoelectric ceramics 3 uses built on stilts process to be placed in shell 5, for built on stilts part 7 below piezoelectric ceramics 3, the height of built on stilts part 7 is 3mm, and amortisseur 4 is positioned at piezoelectric ceramics 3 both sides.Buffer stopper 2 and amortisseur 4 all use the material that shock resistance is good to make.
Operation principle of the present utility model is: by consulting related data and experiment, the efficient deformation amount of piezoelectric ceramics 3 power generation part is 3mm.This device is put in the place that flow of the people is bigger, and power generator 8 is put on ground, and energy collection module 9 is placed somewhere, and the both positive and negative polarity of piezoelectric ceramics 3 is connected in energy collection module 9 by wire.The most invalid mechanical energy that people produces in walking is applied to pressing plate 1 and makes its deformation focused energy, deformation downwards drives buffer stopper 2 to make piezoelectric ceramics 3 deform upon generation electric energy, this time, amortisseur 4 played cushioning effect, alleviated piezoelectric ceramics 3 pressure experienced.When stress is less, piezoelectric ceramics 3 deformation quantity is less than 3mm, and piezoelectric ceramics 3 will not touch inner surface of outer cover 6, and now piezoelectric ceramics 3 deformation quantity is less than built on stilts distance；When stress is bigger; when the theoretical deformation quantity of piezoelectric ceramics 3 has exceeded 3mm; piezoelectric ceramics 3 lower surface will touch inner surface of outer cover 6; thus stop piezoelectric ceramics 3 to continue deformation; the largest deformation amount namely controlling piezoelectric ceramics 3 is 3mm; thus while ensureing maximum generating watt, protection piezoelectric ceramics 3 does not cause because of the stress excessive deformation of excessive generation damaging.The unstable energy that piezoelectric ceramics 3 deformation produces, after energy collection module 9 is collected, just can be changed into stable electrical power storage in energy-storage travelling wave tube 10, for people to use.This apparatus structure is simple, easy to operate；The deformation quantity of piezoelectric ceramics 3 is controlled within 3mm, it is to avoid piezoelectric ceramics 3 causes damaging because of overstress, reduces fault rate, remove from and frequently changing and the trouble of maintenance, extend service life, reduce cost.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
