Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of transmitting transducer and receiving transducer to close the high-frequency transducer that is placed in one.
The object of the invention is to complete by following technical solution, the integral type element of transducer that it is comprised of receiving transducer and transmitting transducer, and receiving transducer is placed in the centre position of transmitting transducer; This integral type element of transducer is placed on metallic support pedestal, and metallic support pedestal below is connected with quad.
As preferably, described transmitting transducer is that two annular PZT4 ceramic components not of uniform size form, and the mode that adopts the little ring of big ring sleeve by two PZT4 ceramic components combinations together.
As preferably, described receiving transducer is circular PZT5 ceramic component, and this circle PZT5 ceramic component adopts inhomogeneous decile cutting, and is spelled and inlayed conglobate receiving transducer by decoupling rubber.
As preferably, between described transmitting transducer and receiving transducer, be coated with one deck sponge rubber.
As preferably, the surface sulfide of described metallic support pedestal has one deck vibration isolation rubber, between this metallic support pedestal and integral type element of transducer, is filled with one deck polyurethane rubber; Integral type element of transducer is placed on metallic support pedestal and the skin being connected as a single entity is coated entirely by polyurethane rubber.
As preferably, the outer of described metallic support pedestal is greater than the size of transmitting transducer outer.
Beneficial effect of the present invention is: 1, the design compressive resistance of high-frequency transducer is 5.5MPa, and transmitting transducer and receiving transducer close and be placed in one, conserve space, whole complete coated polyurethane rubber, vibration and noise reducing; 2, integrated design need be considered structure and the performance of transmitting transducer and receiving transducer simultaneously, comprise whole spatial design simultaneously, utilize Apparent elasticity method and Finite Element to carry out dimensionally-optimised design to ceramic component, effectively suppress the coupling of ceramic component radial vibration mode and longitudinal vibration mode, and utilize the mode of secondary pouring, make integral type element of transducer and metallic support pedestal without being directly rigidly connected, between integral type element of transducer and metallic support pedestal, fill polyurethane rubber, played good vibration isolation effect; 3, whole transducer is entirely coated by polyurethane rubber, without being rigidly connected, has guaranteed the vibration and noise reducing performance of transducer with installed part; 4, transducer inside is without cavity, and there is metallic support pedestal inside, and the outer of metallic support pedestal is greater than the size of transmitting transducer, guaranteed that transducer can work under high hydrostatic pressure.
Accompanying drawing explanation
Fig. 1 is transducer cross-sectional view of the present invention.
Fig. 2 is integral type element of transducer structural representation of the present invention.
Label in accompanying drawing is respectively: 1, receiving transducer, 2, transmitting transducer, 3, metallic support pedestal, 4, quad, 5, sponge rubber, 6, polyurethane rubber, 7, integral type element of transducer, 11, PZT5 ceramic component, 12, decoupling rubber, 21, PZT4 ceramic component, 31, vibration isolation rubber.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done to detailed introduction: as shown in accompanying drawing 1,2, the integral type element of transducer 7 that the present invention is comprised of receiving transducer 1 and transmitting transducer 2, and receiving transducer 1 is placed in the centre position of transmitting transducer 2; This integral type element of transducer 7 is placed on metallic support pedestal 3, and metallic support pedestal 3 belows are connected with quad 4.The outer of described metallic support pedestal 3 is greater than the size of transmitting transducer 2 outers, has guaranteed that transducer can work under high hydrostatic pressure.
Described transmitting transducer 2 is that two annular PZT4 ceramic components not of uniform size 21 form, and adopts the mode of the little ring of big ring sleeve that two PZT4 ceramic components 21 are combined together; PZT4 ceramic component 21, through dimensionally-optimised design, suppresses the coupling of PZT4 ceramic component 21 radial vibration modes and longitudinal vibration mode effectively, has improved emission effciency.Described receiving transducer 1 is circular PZT5 ceramic component 11, PZT5 ceramic component 11 is carried out to inhomogeneous decile cutting, then spell the conglobate receiving transducer 1 of edge by decoupling rubber 12, improved the thickness vibration performance of transducer, avoid horizontal coupled vibrations, widened bandwidth of operation.1 of described transmitting transducer 2 and receiving transducer are coated with one deck sponge rubber 5.
The surface sulfide of described metallic support pedestal 3 has one deck vibration isolation rubber 31, and 7 nothings of this metallic support pedestal 3 and integral type element of transducer are directly rigidly connected, and are filled with one deck polyurethane rubber 6 between the two, have played good vibration isolation effect.Integral type element of transducer 7 be placed on metallic support pedestal 3 and the skin being connected as a single entity entirely coated by polyurethane rubber 6, with installed part without being rigidly connected.Described transducer adopts and first pours into dorsal part, then the mode of overall perfusion, has guaranteed reliability.
High-frequency transducer is divided into following step and is made:
1, metallic support pedestal 3 is processed, and at metallic support pedestal 3 surface sulfide one deck vibration isolation rubbers 31;
