Background technology
Usually, boats and ships or warship etc. are divided into oar ship, sailing boat (wind-force), motor boat (mechanical force being fuel with coal, oil), atomic powered ship (mechanical force by atomic fuel) according to the prime power moved it, existing motor boat is not considered kind and refers to the Power Vessel by the propelling of all mechanical powers, the motor boat of narrow sense refers to the ship moving back and forth driving engine or steam turbine engines had by steam action, have engine petrol, aspirated engine, hot bulb engine, diesel motor motor ship be then called motor vessel.
Except above-mentioned two kinds, also have electric boat, it is divided into diesel-electric boat and the electric boat of turbine two kinds according to electrical generator.Atomic powered ship be existing use atomic fuel to produce steam, and by the motor boat of this steam rotary steam turbine.High temperature and high pressure gas is used to replace the gas-turbine ship of steam except the special ship of high speed of a part, also not yet universal.According to propelling unit, initial motor boat is the paddle steamer of Waterwheel-type, and mainly uses screw propeller ship now.
In small boat, the fin of spiral propeller is 3, and in general ship, the fin of spiral propeller is 4, but in nearest large-scale 1 axle ship, main use fin is the spiral propeller of 5.According to the quantity of the axle of spiral propeller, there are 1 axle ship, 2 axle ships, 3 axle ships, 4 axle ships.In the past, be that a propelling unit has an axle in principle, but also have the situation of two propelling units axle.Small boat also has the screw propeller ship of variable spacing, and it by angle of rake hand of rotation is decided to be equidirectional, and changes the angle of fin, thus changes the pitch of spiral propeller, and can make ship advance, stopping and retreating.
Spiral propeller (screwpropeller) is generally the propelling unit with 3 ~ 7 fins, the flat of thread of fin pushes water open, ship receives the thrust utilizing the reaction force produced when pushing water open to produce and advances, the constant pitch propelling unit (FPP:FixedPitchPropeller) of single spiral propeller is had as the propelling of common warship and boats and ships and direction-changing device, first rotatable propeller (CRP) of adjustable pitch propelling unit (CPP:ControllablePitchPropeller) and compound propulsion device (compoundpropeller), the propelling units such as tandem propeller (Tandempropeller).
The spiral propeller of the propelling unit of existing warship described above and boats and ships is according to the high speed of warship and boats and ships and large scale development, but produce vibration and noise due to the cavitation (Cavitation) produced when warship and shipping high speed travel, described cavitation (Cavitation) refers to, the phenomenon that load high spiral propeller produces when rotating with the rotating speed exceeding certain rotation number, change sentence, be at a certain temperature, reduce pressure and the bubble the phenomenon making it grow of being filled by water vapour or air can be seen.
The spiral propeller of the propelling unit of described existing common warship and boats and ships; easily produce cavitation when load height and reduce propulsion coefficient; cause vibration and the noise of warship and boats and ships; due to the erosion of fin and bending and affect the navigation of warship and boats and ships; and, in order to reorganize and outfit propelling unit, even if under crisis situation; need reorganize and outfit under the state of warship and vessel berth, therefore operating efficiency reduces.
And, when being 35.0 nautical miles/hour for ship's speed upper limit during spiral propeller, when ship's speed more than 35.0 nautical miles/constantly little, vibration and noise can be increased, therefore, except emergency, navigate by water hardly.
Therefore, when the warships such as fast steamer, fire fighting ship, ambulance ship, guard ship and tour ship and boats and ships need rapidity and manoevreability etc. in an emergency situation, the various functions of warship and boats and ships can not be played owing to producing cavitation.And, existing spiral warship and boats and ships on travel direction close to occur collide object time, be difficult to fast rotational and suddenly stop, when capital ship or boats and ships rest in harbour, due to compared to the little warship of radius of rotation and boats and ships very large, therefore, need to rely on the relatively little boats and ships (guiding ship) of radius of rotation just can berth.
In order to solve the marine propulsion that described problem proposed to be improved by No. 10-0956719th, Korean granted patent.
But described marine propulsion, owing to passing through bearings ship screw in guiding tube inside, therefore there is the load acting on guiding tube to increase the weight of, and the problem that the Stability Analysis of Structures of guiding tube reduces greatly, for obtaining direction conversion and the propulsive force of boats and ships, guiding tube one end is incorporated into the steering pipe rotatably combined in the bottom of boats and ships, and with the morphosis of hanging, curling state is formed by bearing at guiding tube internal helicoid propeller screw oar and the 3rd axle, curling state is formed according to bearing at guiding tube internal helicoid propeller screw oar and the 3rd axle, therefore the load acting on described guiding tube entirety can increase the weight of.Therefore, the connecting portion that there is described guiding tube and steering pipe easily deforms or damaged and cause structural shortcoming, and due at the long-time accumulated fatigue load of guiding tube, greatly can reduce the serious problems of the stability of structure.
In order to solve described problem, the marine propulsion improved by No. 10-0956719th, Korean granted patent was proposed.
But described marine propulsion, because the rotation of guiding tube is limited, therefore, when boats and ships will be fallen back, need the screw propeller opposite spin making spiral propeller, therefore need to possess gear shift device in addition, so, there is complex structure and be difficult to maintenance and the problem such as expend.
