A kind of boat-carrying locating and tracking system electric supply installation

Technical field

The utility model belongs to ship electronic applied technical field, is specifically related to a kind of boat-carrying locating and tracking system for Denso Put, follow the tracks of system power supply for ship's fix.

Background technology

Ship's fix is followed the tracks of system and is widely used on ship for civil use, be the navigation safety of boats and ships, in time rescue, And the search etc. after lost contact provides sound assurance.But, existing locating and tracking system is all based on engine and powers , occurring that accident makes engine and whole power system lose efficacy once boats and ships, it is due that locating and tracking system is lost it Function.Additionally, existing locating and tracking system is all external, shipwreck cannot normally work when intaking, boats and ships are illegal After molecule is kidnapped, alignment system is also easily closed or destroys.Therefore, for guaranteeing that ship-positioning system works safely and reliably, need The small power supply of energy-autarchic to be developed, in order to integrated with alignment system and installed by secret.

Content of the invention

Monitor, for spot ship, some problems that system uses and power supply aspect exists, the utility model proposes a kind of ship Carry locating and tracking system electric supply installation.The utility model adopted implementation scheme is that be designed with on the sidewall of upper casing left and right upper ear plate, The end of front-rear side walls is designed with two upper limit planes, lower casing left and right sidewall is designed with lower ear plate, front-rear side walls end all Being provided with two lower limit planes, the length of upper lower casing inner chamber left and right directions and the width of fore-and-aft direction are equal, on upper casing diapire respectively It is provided with the circuit board of transmitter unit through screw；Upper lower ear plate connects through screw, between the upper lower ear plate of the left and right sides respectively Being crimped with cantilever beam type metal substrate, the both sides up and down of metal substrate free end are separately installed with magnet one and coil one, metal The substrate piezoelectric chip bonding with its upper and lower both sides institute constitutes piezoelectric vibrator；Metal substrate width more than upper lower casing lumen width, Piezoelectric chip width is less than upper lower casing lumen width；T-shaped fork is installed on lower casing diapire, fork is cased with from bottom to top successively Balancing spring, magnet two and limit spring, magnet two and magnet one like pole are near installation；On upper lower casing diapire all symmetrical and Being provided with one group of equal coil of quantity two in uniform way, the described coil two that is placed on lower casing diapire with fork center line is all Balanced configuration center.

Repulsive force during inoperative, between the magnet one of piezoelectric vibrator free end and the gravity of coil one and magnet one and two Equal, piezoelectric vibrator does not occurs bending and deformation；When occurring extensional vibration in environment, piezoelectric vibrator is at its end magnets one and line Produce flexural deformation under the effect enclosing an inertia force, vibrational energy is converted into electric energy；Meanwhile, magnet two is at himself inertia force Also up-down vibration under effect；Piezoelectric vibrator flexural deformation and magnet two up-down vibration change magnet one and magnet two and coil one and The position relationship of coil two, makes coil one and coil two cutting magnetic line and produces electric current；During the vibration of other directions, magnet two Inertia force forces fork to produce flexural deformation, changes the distance between magnet two and magnet one and adjacent windings one and coil two, from And make piezoelectric vibrator flexural deformation generating, coil one and the generating of coil two cutting magnetic line；The electric energy being generated is through wire transmission To circuit board, powering for signal transmitter unit after converted process, signal transmitter unit presses set time interval by boats and ships Positional information launch.

During above-mentioned piezoelectric vibrator flexural deformation generating, when ambient vibration intensity is bigger, metal substrate will bear against On upper limit plane or lower limit plane, damage so that it is guaranteed that piezoelectric chip is unlikely because suffered stress is excessive.It in the utility model, is Improve the generating capacity of piezoelectric vibrator and reliability, piezoelectric chip be the PZT4 of 0.2mm, metal substrate be beryllium-bronze, Metal Substrate Plate is 1～2.5 with the ratio of the thickness of piezoelectric chip, now the generating capacity of piezoelectric vibrator compared with strong, energy comparison is big；Energy ratio is Refer to variant thickness than the piezoelectric vibrator first order buckling produced electric energy of deformation and the ratio of maximum therein；For this practicality The novel piezoelectric vibrator utilizing PZT4 and beryllium-bronze substrate to constitute, the reasonable radius of curvature of bound plane isWherein α=h_m/h_pFor thickness ratio, h_mAnd h_pIt is respectively metal substrate and piezo crystals The thickness of piece.

In the utility model, magnet one and coil one that piezoelectric vibrator and its free end are installed constitute single-degree-of-freedom longitudinal vibration System, magnet two constitutes the single-freedom vibration system of any direction with balancing spring, limit spring and fork, due to magnet one And the coupling between magnet two, when fork is bent in any direction deformation, piezoelectric vibrator all produces buckling vibration；Magnet Coupling between one and magnet two makes TRT become two degree freedom system on longitudinal vibration direction, therefore there are two excitation frequencies Rate makes the amplitude of piezoelectric vibrator and magnet two peak value occur.

Advantage and characteristic: when electric supply installation of the present utility model can collect ship's navigation, any direction jolts and vibrational energy Amount, adaptive capacity to environment is strong, effective band width；Piezoelectricity is big with electromagnetic unit synchronous generator, energy force density, piezoelectric vibrator reliability High；Hull recesses can be embedded in as individual components, safe and reliable.
