Abstract
The utility model discloses an anti-sonar anechoic tile made of synthetic rubber. The technical scheme is that holes (1) are formed at the parts near a laying surface of a submarine and are communicated with a sound restraining bin (2) processed at the middle part; holes (3) which are independent spaces are formed at the peripheral part corresponding to the laying surface; the cross sections of the holes (1) and the holes (2) adopt the geometric figures of equilateral hexagons; and the holes (1), the sound restraining bin (2) and the holes (3) are closed and isolated from the outside. Due to the reasonable design, the utility model can not only absorb and lower the self noise of the submarine, but also absorb the sonar waves from the enemies; and sound energy can be converted into heat energy and consumed, thereby reducing the possibility of being detected by sonar and playing a role of soundproofing.
Description
Technical field
The anti-sonar sound eliminating tile of the utility model submarine belongs to the national defense and military fields product, laying facial position near submarine in, it is processed with the regular hexagon hole, the middle part is processed with Shu Yincang, hole communicates with Shu Yincang, and also is processed with the hole that does not communicate with Shu Yincang in the cooresponding peripheral position of the face that lays.The utility model is made by neoprene.
Background technology
From the eighties in last century, the submarine of various countries has all adopted and has laid sound eliminating tile in order to receive and to reduce the noise of submarine, reduce of the detection of hostile sonar to self ship, but style made in Germany in World War II all still follows to the manufacturing of sound eliminating tile in various countries, its principle of work is processed with difform hole at derby or rubber block inside exactly, utilize sound wave in cavity, to vibrate, reduce acoustic reflection intensity, reach sound-deadened purpose.Though this class sound eliminating tile has certain absorption, consumption to the sound wave of self submarine generation, but development along with the sonar detection technology, be not content with application under battle conditions, and because the shape of its inner hole, the design defect of layout, can not receive effectively with the sonar ripple and cut out the sound that produces beyond self ship.
Summary of the invention
The utility model is for improving quietness, the disguise of submarine, reducing to be made by sonar detection.It provides a kind of inside to be processed with the anti-sonar sound eliminating tile of submarine that many evenly distributed orthohexagonal holes and the Shu Yincang that consumes sound, the effect of sonar ripple are made by neoprene.One side cavities of laying (A face) near submarine all communicates with the Shu Yincang of sound eliminating tile middle part, in peripheral position of the present utility model, be processed with hole, its action principle is: when noise that sends when self ship and sonar ripple conduct in the hole, noise and sonar ripple will produce vibrations in hole, fall thereby convert thermal energy consumption to, reach sound-deadened effect by acoustic energy.
Hole near peripheral position does not communicate with Shu Yincang, is an independently space each other.
Description of drawings
Fig. 1 is the positive view of the anti-sonar sound eliminating tile of the utility model submarine.
Fig. 2 is the left cutaway view of the anti-sonar sound eliminating tile of the utility model submarine.
Concrete enforcement
The utility model is described in further detail below in conjunction with Figure of description.
The anti-sonar sound eliminating tile of the utility model submarine shown in Figure 1 lays face (A face) near submarine and is processed with hole 1 in an orderly manner, and its cross section geometric figure is an equilateral hexagon.
The middle part is processed with Shu Yincang 2 in the anti-sonar sound eliminating tile of the utility model submarine shown in Figure 2, and Shu Yincang 2 communicates with hole 1, be processed with hole 3 with laying face (A face) in the symmetrical peripheral position, hole 3 does not communicate with Shu Yincang 2, hole 3 all is space independently each other, hole 1 is all symmetrical on same point with hole 3, and its cross-sectional plane geometric figure is an equilateral hexagon.After treating that this sound eliminating tile inside holes 1, Shu Yincang 2, hole 3 all process, be integral with neoprene plate and finished surface melting welding, the inner space is airtight.
The utility model is owing to adopt the emulation principle, the Cross-section Design of hole 1, hole 2 is become equilateral hexagon, be honeycomb arrangement, can absorb and completely cut off the noise of self submarine, can absorb sonar ripple again from hostile sonar, convert acoustic energy to thermal energy consumption and fall, reduce the possibility that arrived by sonar detection, thereby play sound-deadened effect.
Claims (3)
1. anti-sonar sound eliminating tile of making by neoprene of submarine, it is characterized in that: sound eliminating tile lays in the position of face near submarine and is processed with hole (1), the Shu Yincang (2) of processing communicates in hole (1) and the sound eliminating tile middle part, and is processed with hole (3) in the corresponding peripheral position of the face that lays.
2. the anti-sonar sound eliminating tile of submarine according to claim 1 and 2 is characterized in that: hole (3) is a separate space, does not communicate with Shu Yincang (2), and hole (1) is symmetrical on same point with hole (3).
3. the anti-sonar sound eliminating tile of submarine according to claim 1 is characterized in that: inner space hole (1), Shu Yincang (2), hole (3) are isolated from the outside airtight.
