Abstract
The invention discloses a kind of overflow-type flextensional transducer baffle grillages, mainly include rubber baffle and baffle frame, and rubber baffle is fixed on baffle frame using top platen, side press strip and intermediate fixed swivel nut, the fixed screw bushing structure in both ends.Between fixed plate of the present invention and reinforcing rib by the way of being spirally connected and jumping a queue weldering, while ensureing bonding strength between the two, the depth of parallelism of baffle frame ensure that.Swivel nut, the fixed swivel nut in both ends and end face press strip are fixed among increasing among baffle frame improves the fixation reliability between rubber baffle and baffle frame using acoustic baffles auxiliary fixing structures such as argon arc welding welding moldings between fixed swivel nut and fixed plate bottom outlet.The present invention solves baffle frame fixed plate and the reinforcing rib depth of parallelism is poor, at the phenomenon that in battle array installation process, baffle frame contacts with energy converter and causes rubber baffle to be detached from baffle frame because of the vibration that energy converter generates at work frequent occurrence.
Description
Technical field
The present invention relates to the fields of underwater sound baffle grillage, and in particular to a kind of overflow-type flextensional transducer baffle grillage.
Background technique
Overflow-type flextensional transducer structure is simple, small in size, light-weight, working frequency is low, can deep water work, tie substantially
Structure is to be embedded with ceramic vibrator in elliptical vibration shell, and ceramic vibrator pushes case vibration in the stretching vibration of long axis direction,
And amplify the displacement of long axis direction in short-axis direction, to obtain lower resonance frequency with lesser size.Overflow-type is curved
Energy converter inner cavity water-filling, mutually radiation effect is significant in shell when vibration, it is necessary to acoustic baffle be cooperated to use.Overflow-type flextensional transducing
Device hull vibration can generate biggish amplitude, and acoustic baffle installs fixation by the way that baffle grillage is opposite with energy converter, baffle frame with change
Energy device shell reserves corresponding distance between a period of time, when guaranteeing energy converter high power work, baffle frame will not be with energy converter shell
Body, a period of time generate contact, guarantee that energy converter works normally.
Overflow-type flextensional transducer baffle frame uses TC4 titanium alloy material.Fixed plate and reinforcing rib use groove filled weld
The mode connect, weld seam is longer, and heat output is larger, and speed of welding is difficult to control, and causes entire baffle frame along reinforcing rib direction
Buckling deformation occurs with perpendicular to reinforcing rib direction；Baffle frame fixed plate and the reinforcing rib depth of parallelism are poor, in battle array installation process,
The phenomenon that baffle frame and energy converter contact frequent occurrence, it is difficult to meet requirement.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of overflow-type flextensional transducer baffle
Grillage.
The object of the present invention is achieved by the following technical solutions: this overflow-type flextensional transducer baffle grillage,
It mainly include rubber baffle and baffle frame, baffle frame is mainly made of fixed plate, and the design of fixed plate two sides has reinforcing rib, fixed plate
It is spirally connected between reinforcing rib with screw, the design of reinforcing rib both ends bottom has fixing muscle, is equipped with two in fixed plate on the inside of reinforcing rib
Fixed swivel nut is held, fixed board ends are provided with top press strip, and intermediate fixed swivel nut, rubber are evenly distributed on fixed plate central axis
Glue baffle is fixed on baffle frame using top platen, side press strip and intermediate fixed swivel nut, the fixed screw bushing structure in both ends, both ends
Fixed swivel nut and both ends fixing screws are cooperatively connected, and the fixed swivel nut in centre and intermediate fixing screws are cooperatively connected, rubber baffle point
For both ends rubber baffle, intermediate rubber baffle two parts.
The fixed plate is connect in such a way that more screws are spirally connected and jump a queue weldering with reinforcing rib.
It is connected between the fixed swivel nut in the both ends, intermediate fixed swivel nut and fixed plate bottom outlet using argon arc welding.
The invention has the benefit that
1, using the weldering of jumping a queue that is spirally connected between fixed plate of the present invention and reinforcing rib, avoiding too long export with heat of weld seam causes
Deformation, and ensure that the bonding strength between fixed plate and reinforcing rib.The jump a queue mode of weldering of being spirally connected ensure that the flat of baffle frame
Row degree makes to be bonded closer between rubber baffle and baffle frame, has ensured the adhesive strength of both rubber baffle and baffle frame.
2, the fixation swivel nut among baffle frame of the present invention, the fixed swivel nut in both ends and end face press strip, in rubber baffle and barrier
When grillage is bonded, precompression is applied to bonding plane, improves the adhesive effect of adhesive；In actual use, by baffle frame
Between fixation swivel nut, the fixed swivel nut in both ends and end face press strip, compress rubber baffle and play auxiliary while being adhesively fixed
Fixed effect improves the fixation reliability between rubber baffle and baffle frame.
3, the present invention is referring to GJB.150.16A-2009, in amplitude 10mm, the cycling cycling vibration of frequency 10Hz, acceleration 5g by
Carry out vibration test under force mode, baffle frame reinforcing rib is bolted that the failures such as desoldering, bolt looseness, bolt fracture do not occur is existing
As.It after acoustic baffle Cheng Zhen, is tested through excessive power strike-machine, rubber baffle bonding plane well-tended appearance, non-loosening, obscission.
