Abstract
The utility model discloses a multi-radiating head water acoustic transducer, belonging to the underwater piezoelectric acoustic sensors. The utility model mainly includes a quality block 2, a number of piezoelectric ceramics reactors 3 and a radiating head 1 are connected through a stress screw 4 and the quality block 2. Through adopting the structure that a compound rod composed of the radiating head, the piezoelectric ceramics reactors and the stress screw is fixed on a polygon cylindrical-shaped quality block, the utility model can supply fine sound cylindrical array for middle-or-long-range detection with high-power launch, great depth, high sensitivity receiving, and horizontal non-directional quality in the range of 1 kHz-50kHz frequency.
Description
Technical field
The utility model relates to a kind of transducer, particularly a kind of be used for water electrical signal conversion for to water-borne sound wave or acoustic signals is converted to the piezo-electric acoustical transducer of the signal of telecommunication.
Background technology
Up to now, sound wave is the most effective electric information carrier in the water.Therefore underwater acoustic transducer is to realize important senser element in the military, civilian sonar such as is detected in hydrospace detection, navigation, communication, seabed, also is referred to as to call " ear, the order " of sonar.Present to exist power capacity by single extensional vibration composite bar energy converter little, and horizontal directivity is not strong, and the electroacoustic transfer ratio is lower, the shortcoming that working depth is limited.
Summary of the invention
The purpose of this utility model provide a kind of can for frequency in the 1kHz-50kHz frequency range, high-power emission, the big degree of depth, high sensitivity receive, level non-direction in, remote probe provides many radiation heads underwater acoustic transducer of good garden post acoustic array.
The purpose of this utility model is achieved in that a kind of many radiation heads underwater acoustic transducer, comprises mass 2, and a plurality of piezoelectric ceramic piece heaps 3 and radiation head 1 are connected with mass 2 by stress screw rod 4.Mass 2 is polygon cylinders of band centre bore.Piezoelectric ceramic piece heap 3 is to be formed by the high-temp epoxy glue bond by center piezoelectric ceramic piece with holes, adopts on each piezoelectric ceramic piece electricity to be connected in parallel.
Many radiation heads underwater acoustic transducer provided by the utility model, adopt a plurality of compound bar that constitute by radiation head, piezoelectric ceramic piece heap, stress screw rod to be fixed on structure on the columned mass of polygon, can for frequency in the 1kHz-50kHz frequency range, high-power emission, the big degree of depth, high sensitivity receive, level non-direction in, remote probe provides good garden post acoustic array.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model adopts following structure: a kind of many radiation heads underwater acoustic transducer, comprise mass 2, and a plurality of piezoelectric ceramic piece heaps 3 and radiation head 1 are connected with mass 2 by stress screw rod 4.Mass 2 is polygon cylinders of band centre bore.Piezoelectric ceramic piece heap 3 is to be formed by the high-temp epoxy glue bond by center piezoelectric ceramic piece with holes, adopts on each piezoelectric ceramic piece electricity to be connected in parallel.
When the utility model is made, piezoelectric ceramic piece heap 3 passes through the high-temp epoxy glue bond by the porose piezoelectric ceramic in center, on electricity, potsherd all is connected in parallel, radiation head 1 generally is made of light metal, also be by epoxy glue and piezoelectric pile 3 bondings, finally pass through stress screw rod 4, be connected on the side of polygon Cylinder mass 2 radiation head 1, piezoelectric pile 3.Then all oscillators are adopted in parallel the binding on electricity, draw "+,-" two polar conductors, and put into baking oven, 80 ℃ are incubated 4 hours, drop to room temperature naturally and get final product.
