Description
Technical field
The non-pneumatic shell of stealthy submarine is can be applied to the present invention relates to submarine parts, more particularly to one kind
Can roll over and (tear open) on body or similar plate submarine composite access patch device, to improve submarine
The combination property such as Sound stealth.
Background technology
Access patch is the necessary devices on the non-pressure hull of Modern submarine, is mainly used in personnel and goes out
Enter the closing of hull passage and open system, device and the normal of equipment between the side of a ship to use and examine
Repair.Modern submarine is laid mostly for the purpose of Sound stealth on the non-pressure hull of superstructure
With noise elimination tile structure, but because access patch device is movable part, it is not easy to lay sound eliminating tile,
Therefore, steel reinforcement access patch structure type is at present, can folding door use steel leaf hinge
It is connected with the non-pressure hull of submarine.The access patch of steel stiffened panel structure, to external world active sound
Detectable signal will appear as total reflection feature；And for the vibration radiation inside hull, steel knot
Structure is poor due to damping characteristic, can not carry out effective absorbing or vibration isolation, while when fastening connects
After fitting connection relaxation, access patch will also produce vibration radiation noise, be unfavorable for the overall sound of submarine
The raising of Stealth Fighter.Meanwhile, steel access patch installation weight is larger, and steel loose-leaf is cut with scissors
Chain attachment structure is during the long-term military service of submarine, easy corrosion, is not easy to open and normal
Use.
The content of the invention
The invention aims to overcome the shortcomings of that above-mentioned background technology is present, a kind of energy is proposed
Effectively absorb active acoustic detection signal under water, block internal radiation noise to external diffusion, simultaneously
Also it can effectively mitigate structure overall weight, improve the submarine composite wood of the decay resistance of structure
Expect access patch device.
The present invention is adopted the following technical scheme that to achieve the above object：Submarine composite can be rolled over
Panel assembly, by access patch, hinge webs and is fastenedly connected part and constitutes, the access patch
It is hinged by hinge webs with frame, and frame is fixed in by being fastenedly connected part
On, it is characterized in that the access patch uses core filled composite material plate, the core filled composite material plate table
Layer is acoustic window material, and core is using sound absorption macromolecular material, and the acoustic window material is fiber reinforcement
Laminate, also referred to as FRP；It is described sound absorption macromolecular material be interpenetrating net polymer (IPN) or
Butadiene-styrene rubber, the part that is fastenedly connected door bolt 11 and not is inserted by fiberglass arcuate groove 10, fiberglass
Rust steel sunk screw 12 is constituted, and the fiberglass arcuate groove 10 is located at access patch edge, with that can roll over
The edge of plate is connected, in the horizontal direction of fiberglass arcuate groove 10, i.e., parallel with access patch surface
Direction, which is provided with, inserts latch aperture, and fiberglass is inserted door bolt 11 and is placed in slotting latch aperture, and inserting door bolt 11 in fiberglass is located at
Part in fiberglass arcuate groove 10 is provided with inserts 11 axially vertical screws of door bolt with fiberglass, stainless
Steel sunk screw 12 is engaged with the screw, and the hinge webs are by bearing pin and loose-leaf group
Into loose-leaf is connected with frame and access patch respectively, is set between bearing pin and loose-leaf contact interface
With wear-resistant, corrosion-resistant, and with self-lubricating property liner.
The screw being arranged in the slotting door bolt 11 of fiberglass can be by embedding internal thread stainless steel
Set 13 is constituted.
Access patch of the present invention uses core filled composite material plate structure, and it can be made to expire
The need for sufficient structural strength, can also have preferable sound absorbing capabilities to underwateracoustic detectable signal, together
When construction weight can also effectively be reduced.Because the bearing pin in hinge webs and loose-leaf connect
Being used between tactile interface has wear-resistant, anti-corrosion layer, and with self-lubricating property liner, makes
The etching problem of kinematic coupling portion will be solved effectively, so that the device effectively improved
Service life, is easy to use.Part is being fastenedly connected using the glass with stainless steel sunk screw
Steel inserts door bolt structure, can both ensure the reliability of attachment structure, and steel connection is significantly reduced again
The weight of structure.
The beneficial effects of the invention are as follows can use the same of functional requirement meeting access patch device
When, structure is possessed Sound stealth function, while reducing the weight of structure, improve the corrosion resistant of structure
Corrosion energy.
