Background technology
Ship's fix tracking system is widely used on ship for civil use, be ship navigation safety, in time rescue,
And search and rescue after lost contact etc. provide sound assurance.However, existing locating and tracking system is all based on engine power supply
, when ship accident occurs and engine and whole power system is failed, it is due that locating and tracking system is lost its
Function.In addition, existing locating and tracking system is all external, when shipwreck is intake can not normal work, ship it is illegal
Alignment system is also easily closed or destroyed after molecule is kidnapped.In recent years, to ensure that ship-positioning system safely and reliably works,
People have set about studying the self-power supply device based on piezoelectric, claim piezoelectric generator or piezoelectric harvester, so as to positioning
The system integration and by secret install.However, the ship's fix tracking system piezoelectric generator proposed at present is mostly directly sharp
Encouraged with the additional mass inertia force on piezoelectric vibrator, therefore the energy of a certain fixed direction of vibration can only be collected and resonant frequency can
Tonality is poor；Most critical is that two-way excitation is born in piezoelectric vibrator work, produces compound bending deformation, when ship vibrates in stormy waves
Or shake amplitude it is larger when, fragility piezoelectric is easily because institute's tension stress is excessive and broken.Therefore, to make piezoelectric generator in ship
Be used practically in oceangoing ship locating and tracking system, it is necessary first to the key issue of solution be improve its direction of vibration adaptability,
The adjustability of reliability and resonant frequency.
The content of the invention

Structure and yardstick can be adjusted by the rigidity of buffer spring, balance spring and return spring when determining, so as to realize and ship is run
Vibration frequency of winnowing with a dustpan matches；Meanwhile because the fundamental frequency of piezoelectric vibrator itself is far above the pitch frequency of ship, therefore piezoelectric vibrator
Always work under first-order modal, generating effect is preferable；In addition, piezoelectric vibrator work in be subjected only to driver unidirectional excitation,
The unidirectional deformation for making piezoelectric patches bear compression is only produced, reliability is high.
Advantage and characteristic：Jolting for any direction generates electricity with vibrational energy when collecting ship's navigation, adaptive capacity to environment
By force；Piezoelectric vibrator itself is high without additional mass, fundamental frequency, it can be ensured that is operated under first-order modal, generating effect is good, and system fundamental frequency
It is easy to be adjusted by each spring；Piezoelectric vibrator is subjected only to unidirectional excitation, produces bend in one direction deformation, piezoelectric chip in work
Compression is subjected only to, therefore reliability is high.
