Summary of the invention
The utility model object is to overcome prior art deficiency, provides the underwater acoustic transducer that one effectively defends sea life (being mainly barnacle) to adhere to.
The underwater acoustic transducer of a kind of effective defence sea life of the utility model attachment, it is characterized in that: be made up of acoustical-electrical transducer part (1), shell (2), packed layer (3), metal coupling unit (4), watertight cable (5), polytetrafluoroethylene floor (6) and circlip (7)
Wherein: acoustical-electrical transducer part (1) is placed in shell (2), acoustical-electrical transducer part (1) is connected with watertight cable (5) by metal coupling unit (4), filled up by packed layer (3) between acoustical-electrical transducer part (1) and shell (2), it is outer that described polytetrafluoroethylene floor (6) is sleeved on shell (2), the top of polytetrafluoroethylene floor (6) is fixedly connected on circlip (7), and circlip (7) is sleeved on metal coupling unit (4).
Described shell (2) is the ascending taper of internal diameter, and down, bigger diameter end upward for miner diameter end.
The taper coning angle of described shell (2) is not less than 3 °.
The surface roughness value of described shell (2) is not more than 1.6.
Described acoustical-electrical transducer part (1) is made up of the material of piezoelectric ceramics.
The underwater acoustic transducer of a kind of effective defence sea life attachment that the utility model provides, structure is simple, and it is convenient to assemble, and sealing is strong, and sound translative performance is good, and have extremely low surface energy, sea life not easily adhere to; This transducer face chemical stability is extremely strong, is not easily bondd by marine organism corrsion, and this transducer is having the occasion result of use of water impact better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the underwater acoustic transducer effectively defending sea life to adhere to.
In figure: 1-acoustical-electrical transducer part, 2-shell, 3-packed layer, 4-metal coupling unit, 5-watertight cable, 6-polytetrafluoroethylene floor, 7-circlip.
Embodiment
The utility model acoustical-electrical transducer part 1 is placed in shell 2, acoustical-electrical transducer part 1 is connected with watertight cable 5 by metal coupling unit 4, filled up by packed layer 3 between acoustical-electrical transducer part 1 and shell 2, it is outer that described polytetrafluoroethylene floor 6 is sleeved on shell 2, the top of polytetrafluoroethylene floor 6 is fixedly connected on circlip 7, circlip 7 is sleeved on metal coupling unit 4, and acoustical-electrical transducer part 1(is as piezoelectric ceramics etc.) for being acoustic energy by electric energy conversion, also acoustic energy can be converted to electric energy; Packed layer 3 for entrant sound, and can form the resonance of special frequency channel with polytetrafluoroethylene floor 6; Metal coupling unit 4 is for fixed sound power conversion device 1 and cable etc.; Watertight cable 5 is for transmission of electric signals; Circlip 7 is for fixing polytetrafluoroethylene floor 6, described shell 2 outside surface has one deck polytetrafluoroethylene floor 6 to wrap up, this layer of ptfe surface unusual light, and teflon has extremely strong chemical stability, sea life are not with good adherence of its surface, teflon has low-down surface energy, not easily bonds with other material, so sea life are difficult to attachment; Described shell 2 is the ascending taper of internal diameter, miner diameter end down, bigger diameter end upward, the entirety of underwater acoustic transducer is made to be pyramid type, what be unfavorable for that sea life stop comes off, do not have deposition, the surface roughness value of this shell 2 was not more than for 1.6 [surface roughness Ra (μm) value is not more than 1.6], and described acoustical-electrical transducer part 1 is made up of the material of piezoelectric ceramics.
embodiment 1:as shown in Figure 1, the underwater acoustic transducer of a kind of effective defence sea life attachment, by acoustical-electrical transducer part 1, shell 2, packed layer 3, metal coupling unit 4, watertight cable 5, polytetrafluoroethylene floor 6 and circlip 7 are formed, acoustical-electrical transducer part 1 is placed in shell 2, acoustical-electrical transducer part 1 is connected with watertight cable 5 by metal coupling unit 4, filled up by packed layer 3 between acoustical-electrical transducer part 1 and shell 2, it is outer that described polytetrafluoroethylene floor 6 is sleeved on shell 2, the top of polytetrafluoroethylene floor 6 is fixedly connected on circlip 7, circlip 7 is sleeved on metal coupling unit 4, described acoustical-electrical transducer part 1 is made up of the material of piezoelectric ceramics, described shell 2 is the ascending taper of internal diameter, coning angle is not less than 3 °, case surface roughness Ra (μm) value of cone is not more than 1.6, miner diameter end down, bigger diameter end upward, taper transducer should vertically be installed, packed layer 3 is for entrant sound, and the resonance of special frequency channel can be formed with polytetrafluoroethylene floor 6, metal coupling unit 4 is for fixed sound power conversion device 1 and cable etc., watertight cable 5 is for transmission of electric signals, circlip 7 is for fixing polytetrafluoroethylene floor 6, described shell 2 outside surface has one deck polytetrafluoroethylene floor 6 to wrap up, this layer of ptfe surface unusual light, and teflon has low-down surface energy, not easily bond with other material, so sea life are difficult to attachment.
