Abstract
The invention relates to the field of ships, in particular to a bi-motive-power propulsion system of a ship. The bi-motive-power propulsion system of the ship comprises a diesel engine, wherein the diesel engine drives an axle generator and a propeller through a gear case. The bi-motive power propulsion system of the ship further comprises a power distribution system. Pluralities of electric generators provide power for electric equipment on the ship through the power distribution system. The bi-motive-power propulsion system of the ship is characterized in that the power distribution system can output electric energy of the electric generator to the axle generator, and enables the axle generator to move in the state of an electromotor. The axle generator and the diesel engine provide motive power for the propeller together through the driving of the gear case. The bi-motive-power propulsion system of the ship takes full advantage of existing equipment resources on the ship, and improves the highest speed and maximum towing tension of the ship.
Description
Technical field:
The present invention relates to ship domain, relate in particular to the double dynamical propulsion system of boats and ships.
Background technology:
Existing boats and ships basic propulsion system be main frame, generally all be to be driven by single power sources such as diesel engine or electrical motors, because diesel engine or the corresponding power of electrical motor are definite when design, therefore the emergency speed of boats and ships and maximum towing tension are determined, when boats and ships towing tension or ship speed can't satisfy job requirements, if improve the boats and ships towing tension or increase ship speed, then need former basic propulsion system is replaced by more powerful diesel engine or electrical motor, this equates redesign emergency speed and maximum towing tension and reselect the main frame model.
Simultaneously, because high-performance diesel engine or electrical motor volume are more huge, for some medium and small-scale vessels, be subjected to the restriction of hull size, its emergency speed and maximum towing tension also are subject to the main frame restriction.
Summary of the invention:
The purpose of this invention is to provide the double dynamical propulsion system of boats and ships.It takes full advantage of existing equipments resources on the ship, has improved emergency speed and the maximum towing tension of boats and ships.
The technical scheme of the double dynamical propulsion system of boats and ships of the present invention is achieved in that
The double dynamical propulsion system of boats and ships, it comprises diesel engine and a generator set, diesel engine drives a shaft generator and a screw propeller by gear case, it is characterized in that: it also comprises a power distribution system, described power distribution system can output to the generator set electric energy on the shaft generator, make the shaft generator running at electric motor state, shaft generator and diesel engine drive by gear case and jointly provide power for screw propeller.
The double dynamical propulsion system of boats and ships of the present invention compared with prior art has following advantage:
1. by electrical generator shaft generator is powered, make shaft generator be operated in electric motor state, shaft generator and diesel engine are by the driving of gear case, two kinds of propulsions source are done manual work to screw propeller jointly, the propulsion of ship power range is strengthened, and then improve ship speed or strengthen the bitt towing tension;
2. for medium and small-scale vessel, can by diesel engine and shaft generator jointly for boats and ships provide power, improve emergency speed and the maximum towing tension of boats and ships;
3. can select during boats and ships to cooperate electrical motor jointly for boats and ships provide power than the main frame of small rated power in design, the main frame rating horsepower can be reduced to more excellent type number thus, and volume is also less, it is also little to take cabin space, arrangement convenience can be saved oil consumption, improves diesel engine configuration cost performance.
Power distribution system described above comprises a main switchboard and a PMS power management system.
Screw propeller described above is controllable pitch propeller.
The present invention is described in detail below in conjunction with accompanying drawing:
Fig. 1 is that existing diesel engine or electrical motor single power are as the structural representation of the marine system of main thruster;
Fig. 2 is the structural representation of the double dynamical propulsion system of boats and ships of the present invention.
The specific embodiment:
Be illustrated in figure 1 as existing diesel engine single power propulsion system; it comprises diesel engine 1; diesel engine 1 drives a shaft generator 3 and a screw propeller 4 by a gear case 2; it also comprises a power distribution system 8 and three diesel-engine generators 7 that are connected with power distribution system; described power distribution system comprises main switchboard 8 and the power management apparatus 9 and the safety guard 6 that are arranged on the main switchboard, and shaft generator 3 drives by diesel engine 1 electric power is flowed to consumer 5 on the ship by main switchboard 8.Use boats and ships maximum speed and the maximum towing tension of existing main thruster system to be restricted owing to the diesel engine maximum power.
Diesel engine as shown in Figure 2 and electric motor dual-power propulsion system; it is on the basis of Fig. 1; select the shaft generator 3 ' that can be operated under the electric motor state; when the required speed of a ship or plane of boats and ships or towing tension exceed the power supply ability of diesel engine 1 '; because it is more than needed that three diesel-engine generators 7 ' also have larger electric weight the consumer on storeship during ship design; electric weight more than needed can and be arranged at power management apparatus 9 ' on the main switchboard and the control of safety guard 6 ' outputs to shaft generator 3 ' by main switchboard 8 '; make shaft generator 3 ' be operated in electric motor state; the power of the power of shaft generator 3 ' output and diesel engine 1 ' output is by the driving of gear case 2 '; combined action is on screw propeller 4 '; be implemented under the prerequisite that does not change the marine diesel acc power, strengthen the purpose of ship speed and ship-lifting towing tension.
For making ship operation more flexible, screw propeller 4 ' needs to adopt controllable pitch propeller.
Be a kind of embodiment that provides in conjunction with particular content as mentioned above, can not assert that implementation of the present invention is confined to these explanations.As: the marine main engine type is not limited only to diesel engine, and electrical generator is not limited only to diesel-engine generator, and the quantity of electrical generator is not limited in three etc.All approximate, identical with the inventive method, structure etc., or for making some technology deduction or replace under the inventive concept prerequisite, all should be considered as protection scope of the present invention.
