Description
Technical field
The present invention relates to a kind of ship craft integrated energy resource system, by prime mover directly drive sea water pump it is comprehensive after form ship and move
Power master station send pressurized sea water to each cabin power distribution station through dual redundant power general pipeline, is based on hydraulic power principle, full ship institute
Available energy equipment is realized with the concentrated supply of energy and integrated management all by hydraulic drive, reduces energy conversion number, have vibration
The features such as moving noise is small, power density is high, overall efficiency is high.Be mainly used for scientific investigation ship, research vessel, underwater hiding-machine, marine worker ship with
And general ship etc..
Background technique
According to statistics, in all ends of ship with can be in equipment, 90% the above are mechanical energy form, as propeller, steering engine,
Windlass, loop wheel machine, blower and all kinds of pumpings etc., only less than 10% energy consumption form be electric energy, such as illumination, admittance, control system,
Part is with heat etc., and some crewman are less and end energy consumption that ocean engineering ship that Work machine is more is even less than 1%
For electric energy.
The energy-provision way of traditional ship is that powerful device is directly driven by prime mover, and low-power equipment is driven indirectly by electric energy
It is dynamic.Such as main thruster, side propeller, high power pumping are directly driven by diesel engine, gas turbine or steam turbine, and part is special
The high-power air compressor machine of kind of ship, winch, slush pump, sea water pump, Cargo Oil Pump etc. also take diesel engine prime movers to directly drive
Form, diesel engine up to ten several of equipment are directly operated alone on some ships；And small-power with can equipment then generally by
Prime mover driven generator power generation, is sent electric energy to each electrical equipment by power station, most of electrical equipment needs that motor is arranged
Converting electrical energy into mechanical energy could use, and if steering engine needs motor drive hydraulic pump, hydraulic pump again make by driving hydraulic cylinder
Dynamic device, anchor winch also need motor drive hydraulic pump, and hydraulic pump drives hydraulic motor again, and it is direct that other such as illuminate end
The equipment of electricity consumption and these equipment share a set of power station.It has the drawback that energy multiple conversions, need to add additional energy
Conversion equipment, maximum deficiency are shipment original machine powers much larger than equipment actual power, such as promote mainly into prime mover exist
Power margin cannot be used for the equipment such as power station, winch, crane when the operating conditions such as berthing, underload, same driving other equipment
Prime mover can not be used to drive propeller.
For such deficiency, combined power energy resource system is proposed in industry, also known as complete electric ship, i.e., all prime mover are used
In power generation, in addition to part directly heating equipment is by boiler energy supply, all devices are directly or indirectly driven by electric energy realization, are realized
The concentrated supply of the full ship energy and integrated management, with vibration noise is small, maneuverability is good, comprehensive energy utilization efficiency is relatively high
The characteristics of.Integrated power system is a kind of very promising ship energy supply form, to the insensitive luxury liner of cost, spy
Using more on kind operation ship, combat vessel.There are also born deficiencies for integrated power system, are mainly reflected in three sides
Face.First: energy conversion times are more, for the ship equipment that 90% or more terminal is mechanical energy with energy form, in end
Configuration motor is both needed to for converting electrical energy into mechanical energy, as the main propulsion motor of propulsion converts electrical energy into rotary motion
Mechanical energy, and most ship also needs to configure fluid coupling and reduces transmission shock and vibration, coaxiality deviation, realizes speed regulation
And the functions such as vehicle, clutch, that is, it needs that the mechanical energy of rotary motion is just converted to fluid dynamic energy by pumping, then pass through fluid horse
Up to the rotary machine energy for being converted to driving propeller, the driving to propeller is finally just realized；Second: it is with high costs, for pushing away
Into for the equipment such as device, steering engine, anchor winch, for which increase the generator of corresponding power and motor, and it is matched for it
The frequency conversion equipment of corresponding power, cost are high；Third: fuel oil overall efficiency is not high, and integrated power system biggest advantage is to use
In other use for the non-propulsion load and power station that the partially or completely electric energy of propulsion can be used for that ship full gear is not required to navigate by water
The partial load power of electric equipment can be used for promoting load, the former accounts for major part, i.e., host installation function in traditional propulsion system
Rate often has 20% or more not to be utilized under ship commonly economic running working condition, and integrated power system then solves this
The Utilizing question of 20% installed power more than needed, but the power consumption portion for simultaneously also directly driving prime mover under economic running working condition
Point change into electric power drives indirectly, and the efficiency of fuel oil does not reach maximization.It is most passed through in fact, hybrid power system is only
The marine propuision system of Ji property and reliability, usual optimal degree of mixing are 20% or so, that is, account for ship major part hours underway
Economic running working condition under energy consumption directly driven at full capacity by prime mover, the operating condition under full steam of only a few is auxiliary by electric power power-assisted
Help indirect driving.
Electrification transmission with Fluid-transmission be always transmission field strive long not certainly research topic, different field it is not equal
Scholar also holds different viewpoints, such as robot field, and Japan adheres to always the machine for walking the scheme of Electrified Transmission, and advanced in the world
Qi Ren company boston, U.S.A power then adheres to walking Fluid-transmission technology path always.The high power density of Fluid-transmission, speed regulation
Performance, the characteristics of naturally having revolution and moving back and forth actuator, to determine that it has always in certain special dimensions incomparable
The advantages of, and ship is exactly such a application field.
Ship craft integrated energy resource system based on Fluid-transmission not yet refers in pertinent literature and patent monograph.1973
Year, Britain used auxiliary propulsion plant of the hydraulic-driven as lowsteaming when, United States Patent (USP) in 2000 on one minesweeper
US6099367 proposes a kind of ship fluid power propulsion system, " the Hydraulic Drive in Vessel propulsion that the Wu uncle of University Of Ningbo in 2002 just delivers
Possibility research " in a text, the simple analysis of advantage and disadvantage carried out by the way of fluid power propulsion to Ship Propeling, 2003
United States Patent (USP) US7168997B2 proposes a kind of Hydraulic Drive in Vessel propulsion device of parallel running, Chinese patent in 2008
CN101249884 proposes a kind of ship craft integrated hydraulic propulsion method and device, these documents and patent are mostly for propeller
Load proposes to use the form of Fluid-transmission, no matter and practical in traditional ship promotion program or some electrical power propelling ship
On, majority is installed with fluid coupling, that is, there is this link of hydraulic power, these propulsion modes are referred to as fluid biography
Dynamic form.There is with ship craft integrated seawater energy system proposed by the invention difference substantially above.
This ship craft integrated seawater energy system, overcomes respectively the advantages of having merged Fluid-transmission and integrated power system
The shortcomings that, with total energy approach efficiency is easy compared with high, power to volume ratio is big, power collects, whole ship vibration noise is low, promotes
The low magnetic of system, the system integration is brief, redundancy is strong, energy converts the spies such as number is few, ship's manoeuverability is good, Arrangement of Engine-room is flexible
Point.
