Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
As shown in the figure, this broadband underwater acoustic transducer of anti-deep water mainly comprises 1,30 primitives 2 of base array rack and bearing plate 3, and the respective outer side edges at each position is compact; Simplicity of design is reliable, and primitive 2 is installed in the base array rack 1, and each primitive 2 all is a transmit-receive sharing type transducer; The below of base array rack 1 is provided with bearing plate 3, and bearing plate 3 is a metal material, has strengthened the rigidity of whole energy transducer; Bearing plate 3 is connected with base array rack 1 through screw 4, and bearing plate 3 is provided with extension line hole 5, and each primitive 2 is provided with independent extension line 6 and passes extension line hole 5; What walk from top to bottom is straight line, and such structure makes that overall height dimension is minimum, and the most reliable.Base array rack 1, primitive 2 and bearing plate 3 adopt urethane rubber to carry out integral body sulfuration and encapsulation, and urethane rubber has certain elasticity, and bonding firm, is applicable to the encapsulation of transducer under the high pressure.
Primitive is single matching layer extensional vibration type transducer; Mainly form by matching layer 7, front shroud 8, ceramic component 9 and back shroud 10; The top and the bottom of ceramic component 9 are provided with front shroud 8 and back shroud 10, and the top of front shroud 8 is provided with matching layer 7, and extension line 6 is drawn from ceramic component 9.Primitive 2 adopts the matching layer technology to expand bandwidth; The matching layer material is confirmed in adjustment through multiple material and different proportionings, and the adjustment different height is to confirm optimum matching layer design, and this structural design is simple; Reliability is high, and crushing resistance is strong and acoustic performance is superior.
