Description
Technical field
The present invention relates to ship equipment technical field more particularly to a kind of pod propulsion full circle swinging watercraft electric propulsion systems.
Background technique
Podded propulsion system, full name are " full circle swinging of magneto pod propulsion are without rudder paddle electric propulsion system ".It
Propulsion electric machine not in hull but under water, be made of one with propeller, also without rudder for ship.Entire podded propeller can
It is rotated by 360 ° with horizontal direction, just as modern military aircraft engine using vector spout, rotation gondola can be passed through
Direction is navigated by water to adjust in direction, can not only advance freely, retreat, additionally it is possible to it is various to complete " traversing " and " cast " etc.
" exceedingly difficult movements " greatly improve the maneuverability and mobility of ship.This propulsion mode is due to no any mechanical biography
Dynamic energy loss, so energy conversion efficiency is very high.In addition, there are also several big benefits for this propulsion system, for example save cabin
Strong, vibration noise that ship can be substantially reduced of space, maneuverability and controllability etc..Eliminate tailing axle, stern thruster,
Steering gear system etc. is not required to special cooling system, to save volume of compartment, simplifies installation.Space configuration is flexible, can be in machine
Three-dimensional arrangement, not only convenient, flexible in the entire space in cabin, but also takes full advantage of cabin volume of compartment, be vessel designs, especially stern and
The design of central station of floating dock part provides great flexibility.From the aspect of fire-fighting and safety, generator can also be divided into
Several groups (in the case that such as full ship shares 6 generators, being segmented into 31 group) are arranged in different cabins.As needed certainly
Surely the generator number of units being connected to the grid, makes every unit that can work under more satisfactory load, so not only to diesel engine
Good combustion and beneficial using heavy oil, and maintenance can be reduced and reduce spare part expense.Pod propulsion electric power
Propulsion system can be using the mode of " the double paddles of two-shipper ", and on the quarter lower section, is filled with two sets of podded propellers side by side.It is most
Big benefit is that ship manipulation is got up very flexibly, while safety is also more preferable, if one of propeller is broken, can also use
Another works.
202320761 U of CN discloses a kind of Podded ship electric propulsion system device comprising drives platform, by machine

Above-mentioned Podded ship electric propulsion system is flexibly connected motor and propulsion device, realization is facilitated to load
The adjustment of revolving speed, torque avoids vibration transmitting, noise superposition, improves the service life of component, reduce system maintenance cost, protect
Card system even running.Compared with the propeller of common rudder paddle structure, just because of many excellent of podded propulsion system
More property, podded electric propulsion mode are with a wide range of applications, therefore in terms of marine electric power propulsion field, have been in
Leading position becomes the main R&D direction in one, marine electric power propulsion field, no matter technically or in terms of market,
All become one of the developing direction of Ship Propeling.
But no matter podded propeller or common rudder paddle propeller, have one at present and insurmountable ask
Topic is exactly the cavitation of blade and podded propeller under different situations, and when propeller operates, the pressure oscillation of generation will be led
Cause more air pocket cavitation pittings.Inside 20 DEG C of seawater, if part occurs being lower than the low pressure of 2338.8pa, seawater will
It boils and generates bubble, be exactly vacuole.Liquid at high speed flowing of propeller when rotation around drive, because of positive liquid
Body is thrown out by propeller, and since a large amount of liquid is thrown out from front, the liquid of surrounding, which has little time to be supplemented in, to be come, so
Certain vacuum is just formed at the back side of propeller, the air at this moment contained in liquid, which just overflows, to be come, and overleaf forms bubble, again
Due to the extruding of followed by liquid, bubble is crashed to pieces, so being formed cavitation damage, cavitation damage is not only easy to produce strongly
Cavitation erosion, to blade cause it is serious degrade, when serious, propeller can be enabled to be broken, but also will affect propeller
Propulsive efficiency, seriously affect the use quality of propeller.For the generation for reducing cavitation phenomena as far as possible, propeller mainly adds at present
Anti-cavitation tunnel is filled, such as CN1440346A discloses a kind of anti-cavitation tunnel for marine propeller.The technical value must agree
It is fixed, lift can be generated when water flow flows through socket, improve the thrust transmission efficiency of engine.But the generation of vacuole
Principle is the flow at high speed of liquid moment, and liquid at high speed flowing is the high-speed rotation bring by propeller, therefore, to solve
Vacuole problem, it is necessary to reduce the critical speed that vacuole occurs for propeller, but the problem of this is contradiction, revolution speed of propeller is low
The speed of a ship or plane needed for ship is just not achieved, revolving speed is high just not to can avoid generation cavitation phenomena.Since propeller is uneven after ship
It working in flow field, the non-uniform flow field of seawater results in thrust caused by propeller and torque meeting generating period pulsation,
That is it is not a constant power that this pulsating force, which acts on blade, therefore using can disclosed in 105620728 A of CN
Be capable of the propeller of variable pitch diameter disclosed in the propeller of variable pitch diameter pitch and 104943853 A of CN, according to blade itself from
Mental and physical efforts size controls the two technical solutions of the paddle diameter size of propeller, can not be real by the mode that centrifugal force is produced from driving
Now propeller variable diameter truly, can not obtain stable propulsive force, can not also solve to compensate by changing paddle diameter
The excessively high bring vacuole problem of revolving speed.Therefore, this problem is always to restrict shipbuilding industry development on military and ship for civil use
A great problem.
