Description

A kind of surface vessel device

Technical field:

The utility model belongs to ship's fitting manufacturing technology field, relates to a kind of surface vessel device, and particularly a kind of lower housing portion on existing naval vessel installs navigation equipment in the water of multiple propulsive mechanism.

Background technology:

Along with the upgrading of world today's science and technology competition, the effect of various naval vessel in command of the sea and mastery of the air seems particular importance, is to build ocean power, right-safeguarding law enforcement, defendance maritime territory, and the demand of the fast speed ship of the high-caliber water surface is more outstanding; The screw propeller of the propulsive mechanism on current all naval vessels is almost all arranged on naval vessel afterbody, when turning in naval vessel, can only singlely realize by changing afterbody rudder, the shortcoming such as also exist that the naval vessel radius of gyration is large, maneuvering performance is poor, running velocity is slow, fuel oil consumption waves large, poor stability greatly, under water in large, the stormy waves of noise, its steel plate fatigue strength damage is simultaneously also large, naval vessel is short for service life, directly affects navigation and the using function on naval vessel.

The rudder and propeller of existing ship structure is all arranged on naval vessel rear end tails, existing defects comprises: one be naval vessel turn time, maneuvering performance is poor, very little for a rudder, transfer support, time turning in naval vessel, from afterbody to the naval vessel of the whole gravity of front head and very long distance, cause rudder to rotate sensitivity slowly, naval vessel maneuvering performance is poor; Two is be that the resistance that single rudder is subject to by screw propeller thrust power is especially big when turning in naval vessel, and the time is longer, makes the radius distance of rotation large; Three is when advancing on naval vessel, and in the gravity on whole naval vessel, water, resistance and wind-force only have 1-2 the screw propeller by afterbody to advance, and suffered resistance is too large, causes route speed too slow; Four is that diesel engine mainly leans in present ship power mechanism or steam engine generation dynamic vibration is large, noise is large, add resistance and wind-force in whole naval vessels gravity, water, only tail propeller produces thrust rearward, makes vibrations and noise larger, naval vessel sonar contact usefulness can be made poorer; Five is because rudder and propeller is arranged on naval vessel afterbody, and when naval vessel advances in stormy waves, make naval vessel wigwag motion large especially (without bearing force), stability is also poor; Six is that the rudder and propeller on existing naval vessel is arranged on rear afterbody, and be exposed to outside housing, naval vessel, when normal/cruise, is easy to be wound around by foreign material, makes ship power organ host destroyed and can not travel; Seven is because the gravity on naval vessel is large, navigates by water, depends merely on tail undercarriage and carry out, make naval vessel keel and steel plate produce distortion and fatigue damage, reduce the life-span in distance, the resistance be subject in water for a long time and stormy waves; Eight is because the weight in naval vessel own is large, and be subject to resistance and the wind-force of water, cause route speed slow (the general route speed in current naval vessel is on average at 12-28 joint), and dynamic host fuel consumption is large, during increase by joint nautical mile per hour, fuel consumption increases by more than 50%.

Summary of the invention:

The object of invention of the present utility model is the shortcoming overcoming prior art existence, seek to design that a kind of speed is fast, maneuvering performance strong, it is little to wave, stability good, that keel and steel plate produce the damage of flex fatigue degree is little, naval vessel operation life is long, noise is little under water, endurance is long, the surface vessel that consumption of fuel is low.

To achieve these goals, the agent structure of surface vessel device that the utility model relates to comprises original-pack rudder, original-pack screw propeller, screw propeller, housing, commander's synchro, anchor fitting, abdomen strutbeam, Housing Base, becomes accelerator, actuating unit, flap, circular hole eye, sound isolating layer, command set and naval vessel hold steel plate seat soon; Commander's synchro of an automation installed by the command set on existing naval vessel, and commander's synchro is connected to actuating unit, actuating unit with become accelerator snap ring type soon and be connected to one, and be secured by bolts on naval vessel hold steel plate seat; The both sides, bottom of the housing on existing naval vessel are shaped with screw propeller respectively in tandem, actuating unit is fixedly connected with each screw propeller respectively, the number of screw propeller is set to 2-12 according to naval vessel size and length setting in naval vessel bilateral symmetry, and the screw propeller as propulsive mechanism is fixed as one respectively by the abdomen strutbeam bottom anchor fitting and naval vessel and Housing Base; The outside locating the screw propeller arranged bottom naval vessel is fixedly shaped with the flap of arc-shaped supporting construction, flap and Housing Base are connected as a single entity, flap has circular hole eye, circular hole intraocular footpath is greater than circular hole eye external diameter, the sound wave produced during propeller works can be made to be gone back by the refraction of the inner hole surface of circular hole eye, and the sound conductively-closed that screw propeller is sent; Circular hole eye makes the water flow energy on flap remain unimpeded, fixes the sound isolating layer of snearing one deck elastomeric material in the inner side of flap, and sound isolating layer absorbs the sound that screw propeller produces, and sonar contact usefulness is improved, and strengthens the underwater attack effect on naval vessel.

When the surface vessel device that the utility model relates to advances, first opening power, pushes to commander's synchro, by actuating unit with becoming accelerator drives each propeller rotational soon; The common rotation of 2 ~ 12 screw propellers, make the integral power multiplication of promotion naval vessel, speed is increased to 1.35 ~ 2.2 times before reconstruction, realizes naval vessel and doubles fast to advance; When naval vessel turnon left, intend turning to some screw propellers in left side shut down or reverse, some screw propeller normal operations of opposite side, even realize turnon left rapidly in original place in minor radius; When naval vessel right-hand corner, some screw propellers on right side shut down or reverse, and several screw propeller normal operations of opposite side, even realize right-hand corner rapidly in original place in minor radius, reach the fast reserve effect turned to.

The utility model compared with prior art, its general structure design science, principle is reliable, manufacture and reconstruction cost low, safety performance is good, long operational time, navigating power foot, and consumption of fuel is low, adapts to off-lying sea navigation and comes about flexibly.
