Abstract
The utility model discloses a submarine camouflage umbrella, which is arranged on the front end of a submarine and comprises a main rod, an umbrella rib, an umbrella skirt and a support rod. The main rod and the umbrella rib are made of plastics, the front end of the main rod is provided with the umbrella rib and the umbrella skirt, the rear end of the main rod is inserted in the front end hole of a submarine; the umbrella skirt is made of loose chemical fiber cloth; the support rod is made of elastic plastics, one end of the support rod is connected with the umbrella rib on the edge of the umbrella skirt, and the other end of the support rod is inserted in the front end hole of the submarine. The utility model has a simple structure. When the utility model is used, the umbrella skirt is unfolded to block the submarine and to filter the vibration noise of the submarine and the external acoustics waves, thereby improving the concealment of the submarine. The utility model is applicable to all submarines.
Description
Technical field the utility model relates to a kind of umbrella, the camouflage umbrella net that especially uses on 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.
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 camouflage umbrella simple in structure will be provided, and makes it can filter the dry sound of submarine self vibration and from exterior sound wave, improves the disguise of submarine.
In order to achieve the above object, the submarine camouflage umbrella that the utility model provides is placed in the submarine front end, camouflage umbrella net is except being made up of mobile jib, umbrella frame, full skirt, also has strut, wherein, mobile jib and umbrella frame are made of plastics, and the front end of mobile jib connects umbrella frame and full skirt, and insert in the submarine front aperture rear end of mobile jib; Full skirt is by making than the pory chemical fiber fabric; Strut is made by having flexible plastics, and an end of strut is connected on the umbrella frame at full skirt edge, and the other end of strut inserts in the submarine front aperture.The concrete type of attachment of mobile jib, umbrella frame, full skirt is a prior art, repeats no more here.When the utility model uses, earlier the umbrella body is stretched out from the submarine front end, again mobile jib is pulled back in submarine, make the strut bending, full skirt launches; Not the time spent mobile jib is extrapolated to submarine, strut is stretched, full skirt shrinks, and the umbrella body is regained from the submarine front end again.
The submarine camouflage umbrella that the utility model provides has positive effect: be placed in the submarine front end, camouflage umbrella net is except being made up of mobile jib, umbrella frame, full skirt, also has strut, wherein, mobile jib and umbrella frame are made of plastics, the front end of mobile jib connects umbrella frame and full skirt, and insert in the submarine front aperture rear end of mobile jib; Full skirt is by making than the pory chemical fiber fabric; Strut is made by having flexible plastics, and an end of strut is connected on the umbrella frame at full skirt edge, and the other end of strut inserts in the submarine front aperture, and is simple in structure.Full skirt launches during use, and submarine is sheltered from, and on the one hand, the dry sound of submarine self vibration can be absorbed a part by full skirt; On the other hand, the sound wave that transmits from enemy's active sonar can be absorbed a part by full skirt, and the sound wave that penetrates full skirt is striking the submarine front end when returning, and is absorbed a part by full skirt again, therefore can improve the disguise of 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: submarine front end 1, strut 2, mobile jib 3, umbrella frame 4, full skirt 5.
The submarine camouflage umbrella that specific embodiment the utility model provides is placed in submarine front end 1, camouflage umbrella net is except being made up of mobile jib 3, umbrella frame 4, full skirt 5, also has strut 2, wherein, mobile jib 3 and umbrella frame 4 are made of plastics, the front end of mobile jib 3 connects umbrella frame 4 and full skirt 5, and insert in submarine front end 1 hole rear end of mobile jib 3; Full skirt 5 is by making than the pory chemical fiber fabric; Strut 2 is made by having flexible plastics, one end of strut 2 is connected on the umbrella frame 4 at full skirt 5 edges, the other end of strut 2 inserts in submarine front end 1 hole. and the concrete type of attachment of mobile jib 3, umbrella frame 4, full skirt 5 is a prior art, here repeat no more. when the utility model uses, earlier the umbrella body is stretched out from submarine front end 1, mobile jib 3 is pulled back in submarine again, make strut 2 bendings, full skirt 5 launches; Not the time spent mobile jib 3 is extrapolated to submarine, strut 2 is stretched, full skirt 5 shrinks, and the umbrella body is regained from submarine front end 1 again.
The utility model protection domain relates to all changes form recited above.
