Abstract
The present invention is a kind of sound eliminating tile for realizing the conversion of noise electric energy, to reduce the noise characteristic of submersible and infrared signature, and the acoustic energy of noise is converted into electric energy, so that submersible utilizes.The novelty of the present invention is be encapsulated in piezoelectric ceramics vulcanization in synthetic rubber and sound eliminating tile be made, one group of via corresponds to a piece of piezoelectric ceramics.The one side for having via is connected with submersible housing during laying.Using the acoustic-electric conversion function of piezoelectric ceramics and the inverted trapezoidal structure of via, the acoustic energy for entering sound eliminating tile is converted into electric energy, is recycled after processing for submersible.This special construction of via can greatly improve acoustic-electric transfer efficiency, thereby reduce the conversion between acoustic and thermal, reduce the infrared signature of submersible.
Description
Technical field
The present invention is a kind of sound eliminating tile for realizing noise-electric energy conversion, reduces noise applied to submersible and carries out sound-electric
Conversion.Belong to electroacoustic switch technology field.
Background technology
When submersible navigates by water under water, due to mechanical oscillation, higher noise is inevitably resulted from, so as to make diving
The concealment and battlefield survival of device substantially reduce.The general way in the world is that sound eliminating tile is laid on submersible to drop at present
Low noise.Its working mechanism is exactly that impedance matching is generated between seawater and hull so that and sound wave can enter in sound eliminating tile, by
In the damping action of sound eliminating tile material and the effect of watt internal cavity or filler, convert acoustic waveform, acoustic energy is converted to
Thermal energy is consumed, and so as to which the acoustic wave energy for making return substantially reduces, achievees the purpose that reduce active sonar detection range.It is lacked
Putting is：Although the noise characteristic of submersible can effectively be reduced by doing so, for the submersible of finite energy, it is not only one kind
Energy loss, and the infrared signature of submersible is converted to after thermal energy and increases, increase the possibility being detected.
Invention content
A kind of sound eliminating tile for realizing noise-electric energy conversion.Submersible can be converted into due to the noise that mechanical movement generates
Electric energy stores, and to give power supply for electrical equipment, can also effectively reduce the noise characteristic and infrared signature of submersible.Solve the present invention
The technical issues of used scheme be：First according to submersible shape, the pressure of design and manufacture with definite shape and thickness
Piezoelectric ceramics vulcanization is packaged in synthetic rubber block by electroceramics, and thickness is between 50-200mm, according to the difference of submersible
It is laid in submersible surface by location and shape with epoxy resin.Sound eliminating tile not only can significantly drop made of the piezoelectric ceramics
Acoustic energy can be also converted to electric energy to be supplied to electrical equipment by the sound wave reflected intensity of low active sonar and submersible self-noise
Electricity.According to the density of piezoelectric ceramics surface charge this basic principle directly proportional to suffered pressure, sent out when active sonar
The vibrations and noise contributions of sound wave or submersible itself generation can generate pressure to piezoelectric ceramics, be allowed to produce when the sound eliminating tile
Raw deformation, the opposite charge of both ends meeting polarization, electric current is formed by circuit.It boosts through oversampling circuit, convert can be to latent
The accumulator charging of hydrophone.
The beneficial effects of the invention are as follows：Piezoelectric material vulcanization is packaged in the synthetic rubber block system on the submersible surface that is laid in
Into sound eliminating tile in, using its sound-electric transformation, the acoustic wave energy for entering sound eliminating tile is converted into electric energy, is not only reduced
The possibility that submersible is detected by active and passive sonar also reduces the infrared signature of submersible, and the electric energy of conversion is by processing
Also the accumulator of submersible can be given to charge afterwards.
Description of the drawings
Fig. 1 is the structure diagram of sound eliminating tile part of the present invention.
Fig. 2 is the connection block diagram of circuit part of the present invention.
Specific implementation method
The present invention is described in further detail with reference to the accompanying drawings and detailed description：
The present invention is that piezoelectric ceramics vulcanization is packaged in synthetic rubber block.As shown in Figure 1, each group of via and one piece of piezoelectricity are made pottery
Porcelain corresponds to, and the size and the depth of via are related with the frequency of sound source, and with conducting wire that piezoelectric ceramics and voltage transformation and processing is electric
Road is connected.There to be via to be laid in submersible surface on one side.When the sound wave or submersible itself that other side's active sonar is sent out produce
Raw vibrations and noise contributions can generate pressure when the sound eliminating tile to the piezoelectric ceramics of its inside, be allowed to generate deformation, and two
The opposite charge of end meeting polarization, electric current is formed by circuit.After voltage transformation and processing circuit boosting, transformation
It charges to the accumulator of submersible.According to the frequency range of noise, diameter optional Φ=2 of via, 2.5,3.Shape is upper handle
Big inverted trapezoidal structure.After incident acoustic wave enters via, due to the special shape of via, understand in cavity floor impact several times,
Sound-electric transfer efficiency is improved, ideally, piezoelectric ceramic piece should be made to generate resonance with sound source, improves conversion effect to greatest extent
Rate.
In order to make present invention work relatively reliable, can also increase in voltage transformation and processing module and battery section
Necessary peripheral module.As charging voltage detection module, charge control module, charging current detection module, charging instruction module,
Abnormality detection module, battery temperature detection module etc..
The sound eliminating tile made of present principles can not only significantly reduce the reflected intensity of active sonar sound wave, inhibit submersible
Acoustic energy, can be also converted into electric energy so that submersible is utilized by the vibration and noise, the infrared signature for reducing submersible that itself is generated.
