Underwater vehicle in Xia Shui, dive, deep water navigation, sit the end, float to water surface process, select to have the liaison work that the transducer of different directional properties keeps lash ship and underwater vehicle according to the operating mode different needs.For example water needs to select omnidirectional transducer work to the operating mode of the water surface with floating under underwater vehicle, and under other operating modes, needs to select directional transducer work.At least need two transducers so under existing situation, keep underwater vehicle to communicate by letter with lash ship.
The utility model content
The utility model provides a kind of deep water to use underwater acoustic transducer, and this underwater acoustic transducer compressive property is good, and sound translative performance is good, and has the different sensing of complete, directed combined type, and is simple in structure, be beneficial to Project Realization.
Concrete technical scheme is following:
The said underwater acoustic transducer of the utility model comprises sound passing membrane, extensional vibration compound bar oscillator, pieces together structural members such as edge circle-ring vibrator, annular installing plate, base plate and pipe.Extensional vibration compound bar oscillator comprises base, screw rod and piezoelectric ceramic piece, and it produces one 80 vertical directivity about degree.With screw rod piezoelectric ceramic piece, electrode slice are linked together, be pressed on the base.Piece together the edge circle-ring vibrator and be made up of piezoelectric ceramics bar and electrode strip, it is non-directive in a circumferential direction, can be at all directions sending and receiving signal.The faying face of piezoelectric ceramics bar and electrode strip is coated with epoxy resin bonding and constitutes an annulus together.Piece together the edge circle-ring vibrator and be fixed on the base plate, inside is useful on the pipe that annular installing plate is installed.Extensional vibration compound bar oscillator is fixed on the annular installing plate.Sound passing membrane covers on extensional vibration compound bar oscillator and pieces together edge circle-ring vibrator outside and be tightly connected with base plate.Since extensional vibration compound bar oscillator with piece together to inlay circle-ring vibrator and can satisfy this requirement that possesses different directional properties when the sending and receiving acoustic signals respectively; They are combined; Outside sound passing membrane sealing; Inner perfusion sonar oil has promptly constituted complete, a directed combined type underwater acoustic transducer that ability is worked at the deep-sea.
Further, sound passing membrane is formed through high temperature vulcanized by sound transmitting rubber, and quality is tight, even, and in order to reduce the influence to sound translative performance to greatest extent, sound passing membrane adopts whole sulfurization technology, and outside surface does not have the combination line, and thickness is 2-4mm.
Further, the annular seal groove is arranged on the base plate, the sealing surface of sound passing membrane and ring-shaped groove coupling, the sealing surface of sound passing membrane and the sealed groove face on the base plate carry out butt-end packing, and annular pressing plate is pressed on the ring surface of sound passing membrane in the sealed groove.
Further, piece together perforate on the pipe circumference that edge circle-ring vibrator inside is used for fixing annular installing plate and be beneficial to overflowing of bubble in the sonar oil.
The beneficial effect of the utility model is: the transducer sealing is reliable, can the inside and outside high hydraulic pressure of active balance transducer.Extensional vibration compound bar oscillator is inlayed the circle-ring vibrator parallel connection with piecing together, and can satisfy underwater vehicle requirement to different directive property under different operating modes.Also can according to circumstances use extensional vibration compound bar oscillator to improve sound source level separately, increase communication distance; And can (being not less than 8000 meters) normal reliable work under the big degree of depth.
