Description
Technical field:
The utility model relates to a kind of jet-propelled marine propuision system, is used for the propulsion of ship technical field.
Background technology:
In the prior art, propeller propulsion system is adopted in the propelling of boats and ships more, its energy transfer process is: the chemical power of fuel changes heat energy into by burning, heat energy changes mechanical energy output into by driving engine, is delivered to screw propeller by change-speed box, changes the mechanical energy of screw propeller into, propeller-driven water flows and changes the kinetic energy of water into, the efficient low (having only about 30%) of transfer route length, driving engine and screw propeller, power utilization is not high, and speed of the ship in meters per second is not increased.Therefore, how improving the propulsion system of boats and ships, thereby improve the dynamic property and the manoevreability of boats and ships, is technical problem to be solved in the utility model.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of jet-propelled marine propuision system, has speed height, characteristics that energy utilization rate is high.
For achieving the above object, the utility model adopts following technical scheme: a kind of jet-propelled marine propuision system, include hull, it is characterized in that: be provided with combustion chamber in hull, air pump, electric-controlled injection oil pump link to each other with combustion chamber respectively, air filter links to each other with air pump, fuel tank links to each other with the electric-controlled injection oil pump, and turbo-machine links to each other with combustion chamber, and electrical generator links to each other with turbo-machine, air nozzle is located at the afterbody of hull under water, and is connected with the exhausr port of combustion chamber.
Principle of work of the present utility model is as follows:
During work, fuel oil and air are ejected into the combustion chamber internal combustion by electric-controlled injection oil pump and air pump with it respectively, and the high temperature and high pressure gas of generation directly ejects from the air nozzle under water of hull afterbody, air-flow that ejects and water generates antagonistic force promote hull and advance.On the other hand, a part of kinetic energy of combustion chamber is supplied with to auxiliary turbo-machine and electrical generator, offers the electric power and the supply of power of hull interior.
The beneficial effects of the utility model are: the utility model is because driving engine, change-speed box, the propeller system in the middle of not having, efficient greatly improves, energy utilization rate also greatly improves, emitted dose, change airshed and speed by changing electric-controlled injection oil pump and air pump change speed of the ship in meters per second.Have speed of the ship in meters per second height, characteristics that energy utilization rate is high.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of jet-propelled marine propuision system includes hull 8, is provided with combustion chamber 5 in hull 8, air pump 2, electric-controlled injection oil pump 4 link to each other with combustion chamber 5 respectively, air filter 1 links to each other with air pump 2, and fuel tank 3 links to each other with electric-controlled injection oil pump 4, and turbo-machine 6 links to each other with combustion chamber 5, and by combustion chamber 5 drivings, electrical generator 7 links to each other with turbo-machine 6, and air nozzle 9 is located at the afterbody of hull 8 under water, and is connected with the exhausr port of combustion chamber 5.
Principle of work of the present utility model is as follows: during work, fuel oil and air, by electric-controlled injection oil pump 4 and air pump 2 it is ejected into combustion chamber 5 internal combustion respectively, the high temperature and high pressure gas that produces directly ejects from the air nozzle under water 9 of hull 8 afterbodys, air-flow that ejects and water 10 produce antagonistic force, promote hull 8 and advance.The utility model is not owing to have middle driving engine, change-speed box, propeller system, and efficient greatly improves, and energy utilization rate also greatly improves, and emitted dose, change airshed and speed by changing electric-controlled injection oil pump 4 and air pump 2 change speed of the ship in meters per second.On the other hand, a part of kinetic energy of combustion chamber 5 is supplied with to auxiliary turbo-machine 6 and electrical generator 7, offers hull 8 in-to-in electric power and supply of power.
