Abstract

The utility model discloses a submarine hidden cover, which comprises a cover body, a floating ball and a stone weight, wherein the cover body is made of comparatively loose chemical fiber net cloth, the floating ball is made by wrapping a plastic hollow ball by the chemical fiber net cloth; the stone weight is made by wrapping cobble stones by the chemical fiber net cloth; the floating ball and the stone weight are fixed onto the cover body and irregularly distributed in order to enable the surface of the cover body to form an irregular concave-convex shape to enhance a disguise effect. The submarine hidden cover enhances the disguise effect, and is simple and convenient in operation when in use, capable of increasing secrecy and safety of a submarine and adaptable to all submarines.

Description

Submarine concealing shade

Technical field the utility model relates to a kind of concealing shade, in particular for the concealing shade of hidden submarine.

The background technology disguise is a big feature of submarine.Because the shell of submarine is by the metal manufacturing, smooth and reflective sound wave, even if thereby after adding sound eliminating tile, submarine is still found by active sonar easily.Therefore, if can when eliminating the dry sound of submarine self vibration, absorb, then help improving the disguise of submarine from exterior sound wave.Particularly be at submarine and mourn in silence when hiding, concealed height is directly connected to the latent time and the safety of submarine.

Chinese patent CN1376615 number disclosed " skin-movable indistinctly finding submarine " patent (application number: 00122069.1), its appearance exactly likes animal skin, deck store reaches up and down and loads onto sound absorbent rubber covering deck store surface on the wall, the electricity of storage battery (or electrical generator) offers the electric control dish, resupply noiseless electromagnetic motive device, little slowspeed machine are installed, after the tail of a pair of active section joint activity, the submarine skin plates one deck elasticity skin at the submarine deck store; Submarine clocklike swings by " skin " of whole body movable tail and advances; Do not have propelling unit, steering rudder, fin, noise is little, does not have changeless echo.The weak point of this patent is: submarine clocklike swings by " skin " of whole body movable tail and advances, can't lifting; Therefore tail swing and the ship body is motionless still has echo.

The summary of the invention the purpose of this utility model is exactly that a kind of submarine concealing shade simple in structure will be provided, and submarine being in mourning in silence increases disguise when hiding, and improves latent time and safety.

In order to achieve the above object, the submarine concealing shade that the utility model provides is weighed down by cover body, ball float, stone to be formed, and wherein, cover body is by making than the pory chemical fiber mesh cloth; Ball float is wrapped up in the plastic hollow bag with chemical fiber mesh cloth and is made; Stone weighs down with chemical fiber mesh cloth makes the pebbles parcel; Ball float and stone weigh down and are fixed on the cover body, are irregular distribution, make the surface formation fitfull of cover body concavo-convex, increase camouflage effectiveness.When the utility model uses, cover body is laid on the submarine top gets final product.

The submarine concealing shade that the utility model provides has positive effect: simple in structure, form by cover body, ball float, stone bob, and wherein, cover body is by making than the pory chemical fiber mesh cloth; Ball float is wrapped up in the plastic hollow bag with chemical fiber mesh cloth and is made; Stone weighs down with chemical fiber mesh cloth makes the pebbles parcel; Ball float and stone weigh down and are fixed on the cover body, are irregular distribution, make the surface formation fitfull of cover body concavo-convex, increase camouflage effectiveness.During use cover body is laid on the submarine top and gets final product, easy and simple to handle; On the one hand, the dry sound of submarine self vibration can a quilt cover bulk absorption part, on the other hand, the sound wave that transmits from enemy's active sonar can a quilt cover bulk absorption part, and the sound wave that penetrates cover body is striking the submarine front end when returning, a quilt cover bulk absorption part again, therefore the disguise and the safety that can improve submarine is applicable to all submarines.

Description of drawings the utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:

Accompanying drawing 1 expression scheme drawing of the present utility model.

Structure shown in the accompanying drawing 1 comprises: cover body 1, and ball float 2, stone weighs down 3, submarine 4, seabed 5.

The submarine concealing shade that specific embodiment the utility model provides weighs down 3 by cover body 1, ball float 2, stone to be formed, and wherein, cover body 1 is by making than the pory chemical fiber mesh cloth; Ball float 2 usefulness chemical fiber mesh cloth are wrapped up in the plastic hollow bag and are made; Stone weighs down 3 usefulness chemical fiber mesh cloth the pebbles parcel is made; Ball float 2 and stone weigh down 3 and are fixed on the cover body 1, are irregular distribution, make the surface formation fitfull of cover body 1 concavo-convex, increase camouflage effectiveness.When the utility model uses, cover body 1 is laid on submarine 4 tops gets final product.

The utility model protection domain relates to all changes form recited above.
