Description
Technical field:
The utility model relates to ship domain, relates in particular to a kind of diesel engine for boats and anti-for shaft generator combined power system.
Background technology:
The basic propulsion system of existing boats and ships is main frame, adopts diesel engine or electrical motor single power source to drive more, and its emergency speed and maximum towing tension are all definite when design, and the corresponding power of diesel engine is also definite thus.For high-power diesel engine, the amount of fuel of its corresponding consumption is inevitable higher.And boats and ships often can run into the situation of the low speed of a ship or plane in when navigation, due to this moment the diesel engine horsepower output lower, main frame decrease in efficiency, and the burnup of boats and ships is still very high, can't satisfy the economical and energy saving requirement of boats and ships.
Summary of the invention:
The purpose of this utility model is to provide a kind of diesel engine for boats and anti-for shaft generator combined power system.It has improved the main frame efficient of boats and ships under low operating mode, has reduced waste of fuel.
A kind of diesel engine for boats described in the utility model and anti-technical scheme for shaft generator combined power system are achieved in that
A kind of diesel engine for boats and anti-for shaft generator combined power system, it comprises larboard diesel engine, larboard gear case, starboard diesel engine, starboard gear case, the larboard diesel engine drives respectively a larboard shaft generator and a larboard screw propeller by the larboard gear case, the starboard diesel engine drives respectively a starboard shaft generator and a starboard propeller by the starboard gear case, it is characterized in that: be provided with a power distribution system between the shaft generator of described two sides of a ship, the shaft generator of a side of a ship is another side of a ship shaft generator power supply by described power distribution system; Make this another side of a ship shaft generator operate in electric motor state, and drive corresponding screw propeller by the gear case with its driving.
A kind of diesel engine for boats described in the utility model and anti-compared with prior art have following advantage for shaft generator combined power system:
1. when the low operating mode navigation of boats and ships, by the electric energy counter shaft generator of supplying with the be operated in electric motor state of another side of a ship of power distribution system with the shaft generator generation of a side of a ship, make this shaft generator by the driving of gear case, side of a ship screw propeller same with it done manual work.Reach a diesel main engine and drive simultaneously two side of a ship screw propellers by two shaft generators, the purpose that another diesel main engine is out of service, because a diesel engine drives two side of a ship screw propellers simultaneously, strengthened the horsepower output of this main frame, it is operated under high work condition state, improve the work efficiency of this main frame, reduced the fuel oil waste.
2. the engineering staff can freely control any side of a ship diesel engine running, be operated in the electrical generator state with this diesel engine with the shaft generator of the side of a ship, the shaft generator of another side of a ship is operated in electric motor state, drive with this and be in the electric motor state shaft generator with the screw propeller motion of the side of a ship, so that the engineering staff overhauls or maintaining out-of-work diesel engine.
Power distribution system described above comprises a main switchboard and a PMS power management system.
Larboard screw propeller described above and starboard propeller are controllable pitch propeller.
A kind of diesel engine for boats described above and anti-also comprise the power station for shaft generator combined power system, the power station can be consumer power supply on ship by power distribution system, or to being in shaft generator under electric motor state for electrical alignment.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in detail:
Fig. 1 is described a kind of diesel engine for boats and anti-structural representation for shaft generator combined power system.
The specific embodiment:
a kind of diesel engine for boats as described in Figure 1 and anti-for shaft generator combined power system, the main frame of boats and ships adopts diesel engine, this system comprises larboard diesel engine 1, larboard gear case 2, starboard diesel engine 1 ', starboard gear case 2 ', larboard diesel engine 1 drives respectively a larboard shaft generator 3 and a larboard screw propeller 4 by larboard gear case 2, starboard diesel engine 1 ' drives respectively a starboard shaft generator 3 ' and a starboard propeller 4 ' by starboard gear case 2 ', be provided with an electrical panel between the shaft generator of described two sides of a ship, electrical panel is provided with the PMS power management system.
described two side of a ship shaft generators all can be operated in electric motor state, when boats and ships are in low work condition state lower time, larboard diesel engine 1 drives larboard shaft generator 3 by larboard gear case 2 and is operated in the electrical generator state, larboard shaft generator 3 outputs to starboard shaft generator 3 ' by electrical panel 8 and PMS power management system 6, make starboard shaft generator 3 ' be operated in electric motor state, starboard shaft generator 3 ' does work to starboard propeller 4 ' by starboard gear case 2 ', the throw-out-of clutch starboard diesel engine 1 ' of starboard gear case 2 ', close simultaneously starboard diesel engine 1 ', complete the monochord diesel engine and drive simultaneously two side of a ship screw propellers promotion vessel motions, make one-sided diesel engine still can be in the state of high operating mode work when the low operating mode navigation of boats and ships.
Equally, the system of the present embodiment also can adopt and close larboard diesel engine 1, and the mode that drives two side of a ship screw propellers promotion vessel motions with starboard diesel engine 1 ' improves fuel utilization ratio and main frame efficient.
Described two side of a ship screw propellers of the present embodiment are controllable pitch propeller; system comprises that also a power station 7 is 5 power supplies of consumer on ship by main switchboard 8; or the shaft generator that is under electric motor state is supplied electrical alignment, a safety guard arranges 6 on described main switchboard.
Be a kind of embodiment that provides in conjunction with particular content as mentioned above, do not assert that concrete enforcement of the present utility model is confined to these explanations.All approximate, identical with the utility model method, structure etc., or for making some technology deduction or replace under utility model design prerequisite, all should be considered as protection domain of the present utility model.
