Abstract

Disclosed is an added noise elimination, anti-winding and accelerating device for a Chinese submarine propeller. In the position of the propeller of a submarine, or an aircraft carrier or a warship of the Chinese navy, a conical pipe is designed to cover the propeller. The conical pipe wall can be composed of seven layers or nine layers or more. The innermost layer and the outermost layer are made of metal materials, and all the middle layers are made of noise elimination materials so that noise can be eliminated. A plurality of holes are uniformly distributed in the front end of the conical pipe. A plurality of sharp automatic cutting knives are arranged outside the holes to protect water inlets against being blocked and prevent long and large sundries from entering so that anti-winding can be achieved. The innermost layer and the outermost layer of the tail end of the conical pipe have no holes so that water can be sprayed intensively to form columns to strengthen thrust, and accordingly accelerating can be achieved. The integrated three-function device is innovatively designed for the tail portions of submarines, aircraft carriers and warships of the Chinese navy.

Description

It is the newly-increased anti-tangle speeder of noise elimination of Chinese submarine propeller

Art；

It is the newly-increased anti-tangle speeder of eliminating the noise of Chinese submarine propeller the present invention relates to reformed AHP at my army's submarine, aircraft carrier, warship propeller, belongs to my warship ship class field.

Background technology；

At present,Known all submarines,Aircraft carrier,Naval vessels,Ship is advanced by the rotation driving of propeller high speed,The sound wave that propeller and main frame are sent under water can be transmitted to far,Other side just can measure and find the azimuth-range even rank that sound wave source sends by sonar,Naturally weedy and artificial fishing net is intricate under water,Propeller is directly exposed very dangerous outside storehouse,Once there is the thing of weeds fishnet winding screw oar,It is exposed in submarine,Aircraft carrier,The thrust produced by propeller rotation outside warship storehouse not only spreads backward but also to around round,It is likely to the thrust of loss 1/6th or 1/5th,If as jet plane does not have taper air jet pipe in tail end,The air-flow for being sprayed is exactly scattered not concentrate,Being lost from many thrusts makes its pace not reach most preferably,I thinks submarine in water,Aircraft carrier,Also patibhaga-nimitta is same for the airscrew thrust principle of warship,3 aspect problems have carried out Improvement innovation to more than,Do not know can be my army's submarine,Aircraft carrier,Warship plays corresponding protection facilitation,So in my army's submarine,Aircraft carrier,The energy device of anti-tangle speedup one three of eliminating the noise is installed necessary in warship storehouse by main frame and at the external spiral oar of storehouse.

The content of the invention；

The technical solution adopted for the present invention to solve the technical problems is；At my army's submarine, aircraft carrier, the propeller of warship; design taper long tube is covered with propeller; taper long tube can design 7 layers 9 layers or more than 9 layers; innermost layer and outermost layer metal material; middle each layer can just be eliminated the noise with sound insulation deadener; taper long tube front end is uniformly porous; have outside hole and several automatic cut thing knife and protect inlet opening not block up sharp; preventing bigger material long from entering just can be anti-tangle; taper long tube tail end most in outermost layer it is non-porous, delivery port and it is small make it produce water spray to be concentrated into post enhancing thrust just can speedup.

The beneficial effects of the invention are as follows；For my submarine aircraft carrier warship afterbody innovation is escorted, break 1.852 law speedups.

Brief description of the drawings；

With reference to the accompanying drawings and examples, the invention will be further described；

Fig. 1 is the anti-tangle speeder structural representation of submarine propeller noise elimination of the invention.

In Fig. 1；1st, submarine, 2, it is automatic cut thing knife, 3, the anti-tangle inlet opening of Taper Pipe, 4, propeller, 5, Taper Pipe eliminate the noise anti-tangle speedup cover, 6, Taper Pipe afterbody water jet, 7, submarine rudder, 8, XS sections, (9) fixing bolt.

Specific embodiment；

After only ratifying through naval of China scientist and military strategist's research demonstration accreditation general assembly Central Military Commission, could be in my army's submarine, aircraft carrier, warship afterbody implements the present invention, in the case of submarine (1) internal structure is not changed, the Taper Pipe anti-tangle speedup cover (5) of noise elimination is designed with reference to propeller (4) size, the anti-tangle inlet opening of Taper Pipe (3) redesign is manufactured and has installed and cut thing knife (2) automatically in the eliminate the noise Front-end Design of anti-tangle speedup cover (5) of Taper Pipe, Taper Pipe anti-tangle speedup cover (5) of eliminating the noise is fixed on submarine (1) afterbody covered with propeller (4) with fixing bolt (9), submarine rudder (7) is installed again, through after the assay was approved, submarine (1) main frame can be started, Taper Pipe afterbody water jet (6) can just spray water and be concentrated into post enhancing thrust；On eliminate the noise will be between the anti-tangle inlet opening of Taper Pipe (3) and Taper Pipe afterbody water jet (6) XS sections (8) in it is several layers of it is middle install sound insulation deadeners, sound insulation deadener is similarly installed around main frame in storehouse and can be only achieved optimal soundproof effect, also many substantial amounts of research and design experiment works will be done, arduous distinguished naval's scientists, certainly；My army's submarine already has more advanced more scientific more sophisticated more practical noise elimination technique, and this energy device of one three is that love China prevents powerful opening one's minds and wish.

Claims

1. a kind of can be the newly-increased anti-tangle speeder of eliminating the noise of Chinese submarine propeller, it is characterized in that；1st, submarine, 2, it is automatic cut thing knife, 3, the anti-tangle inlet opening of Taper Pipe, 4, propeller, 5, Taper Pipe eliminate the noise anti-tangle speedup cover, 6, Taper Pipe afterbody water jet, 7, submarine rudder, 8, XS section, 9, fixing bolt connection constitutes.
