Description
Technical field
The utility model relates to underwater sound equipment technical field, especially a kind of protective device of underwater acoustic transducer.
Background technology
Underwater acoustic transducer and a battle array cable thereof are the current topmost technological means of undersea detection of carrying out, and deep-sea Underwater Detection must rely on transducer and battle array cable thereof that can deep water work.
The transducer long-term work that deep water uses is in deepwater environment; sufficiently high hydrostatic pressing must can be tolerated; needed to make the structure of transducer to possess good sound translative performance and both ensured that underwater acoustic transducer can effectively be worked; this brings a difficult problem just to the resistance to hydrostatic pressure design of transducer; the resistance to deep water performance of deep water transducer can not realize by the mechanical strength of strengthening transducer architecture simply, generally will be equipped with corresponding protective device to underwater acoustic transducer.
Conventionally underwater acoustic transducer is positioned in a stiff case, due to the demand of transducer entrant sound, this stiff case needs the area of some contact aqueous medium to be designed to entrant sound window, sound transmitting window is metallic film structure or the rubber sealant of seal welding normally, the mechanical strength of sound transmitting window structure itself is held the unidirectional hydrostatic pressure from transducer sound transparent layer outside while can't stand the work of transducer deep water conventionally, damaged by deep water hydrostatic pressing for fear of weak sound transmitting window position, conventionally fill the good fluid oil of insulation property in the seal chamber inside of deep water transducer.Like this, when transducer is in the time that deep water uses, the inside and outside pressure of its saturating window is balance, and the structural strength of sound passing membrane requires also just to greatly reduce.
Although above-mentioned protective device can solve entrant sound and the withstand voltage protection problem of transducer in deepwater environment to a certain extent, also come with some shortcomings, mainly:
1, very high to the seal request of cavity, if there is small hole, the liquid oil in housing will successively be overflowed and water will synchronously infiltrate, and cause the fatal destruction to transducer insulation property;
2, requiring of vacuumizing while filling with oil is high, because oil flows, disperse remaining micro-bubble in oil also moves about, if vacuumize not thorough while filling with oil, when after transducer long-term storage, these remaining gases will be condensed into bubble, if the movable acoustical behavior that will affect transducer to the sensitive area of transducer.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of protective device of underwater acoustic transducer, can effectively improve the water-stop effect of underwater acoustic transducer, and does not affect the susceptibility of underwater acoustic transducer.
In order to solve the problems of the technologies described above, the utility model comprises the stiff case for placing underwater acoustic transducer, is provided with entrant sound window on described housing, and the acoustic window material with water sealing property is set in described entrant sound window, it is characterized in that, described enclosure interior is also filled with silicon gel.
Further, on described housing, be also provided with gum-injecting port and exhaust outlet, on described gum-injecting port and exhaust outlet, be provided with sealing device.
The silicon gel that enclosure interior is filled not only has excellent insulation property, sound translative performance, acoustical coupling performance and chemical stability; and possesses the necessary isotropism pressure of deep-water pressure compensative material transmission characteristic; this material is gel state after filling and solidifying; enough soft; deformation arbitrarily under external force; make the pressure of its protective device inside and pressure transmission and liquid basic identical, therefore the utility model can provide better mechanical protection effect
The silicon gel of enclosure interior does not flow substantially, firmly firm with the accurate adhesion of each structural member in closed chamber, thereby residual gas can the agglomerating variation that causes transducer performance of aggegation, like this no matter how the state of transducer changes, the performance base of transducer originally can remain unchanged, and significantly promotes job stability and the reliability of deep water transducer and battle array cable.
The silicon gel of enclosure interior has good hydrophobic and water resistance, even if there is Seepage in the seal chamber of transducer, the sensitive structure of transducer is still wrapped up by silicon gel body, water is still difficult to permeate near transducer electrode, thereby affect the dielectric strength of transducer, transducer still can continue to use in principle.
Although the silicon gel of enclosure interior is solid-state, but possesses good self-reparing capability, after material is torn and comes and again contact, can possess and again be bonded into the ability being integrated, so when transducer is subject to unexpected injury, after the structure of packing material is damaged, this material can digest damage to a great extent voluntarily, rebuild pressure compensation structure adaptively realizes self-regeneration.
The chemical analysis of silicon gel of enclosure interior own is comparatively pure, chemical property stable; also completely cut off other chemical substances flowing in cavity as solid; so the inner sensing unit of transducer can obtain reliably protecting, oil-filled transducer often there will be the problems such as the impure corrosion transducer of oil plant sensing unit.
In sum, the utility model, as the protective device of underwater acoustic transducer, will be significantly improved the reliability and stability of underwater acoustic transducer, and this is significant for being worth high deep water underwater sound equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The embodiment that the utility model is cited; just for helping to understand the utility model; should not be construed as the restriction to the utility model protection range; for those skilled in the art; do not departing under the prerequisite of the utility model thought; can also the utility model be improved and be modified, these improvement and modification also fall in the scope of the utility model claim protection.
As shown in Figure 1, the utility model comprises the stiff case 2 for placing underwater acoustic transducer 1, on described housing 2, be provided with entrant sound window 3, the interior setting of described entrant sound window 3 has the acoustic window material 4 of water sealing property, and described housing 2 inside are also filled with silicon gel 5.
For the convenient silicon gel 5 that injects, on described housing 2, be also provided with gum-injecting port 6 and exhaust outlet 7, on described gum-injecting port 6 and exhaust outlet 7, be provided with sealing device.
While using the utility model; open steam vent and the hole for injecting glue of protective device closed chamber, inject the good silicon gel 5 of auxiliary tone from hole for injecting glue, should be according to inner structural features when perfusion glue; the attitude of rationally adjusting protective device, makes glue can be full of the inside die cavity of whole protective device.
As required the protective device after encapsulating is carried out to Fruit storage, gas remaining in perfusion glue is further got rid of clean.During due to vacuum degassing, bubble overflows with bubble and takes away part glue, needs to arrange in time to supplement glue in degasification process, makes the protective device inside cavity after degassed still be full of glue.Then adopt mechanical seal or chemical means by hole for injecting glue and steam vent encapsulation process.Then,, according to the solidifying requirements of the silicon gel of selecting, the transducer after encapsulating is cured to processing.Finally, with gasoline, comprehensive clean is carried out in the surface of the transducer after encapsulating.
