Abstract
There is a variable pitch screw (4) that is fixed at the stern part of the ship behind the rudder (3), which is supported upon a supporting base (5) and is given motion by of the dead water created by the propeller of the ship (2); it transmits the motion by means of axles and gears (6) (10) to the generator (7) which is connected to an electric panel (9), which by means of a hydraulic system of moving the screw adjusts and controls the production of electric power depending on the needs of the ship.
Description
PROPELLER DRIVEN GENERATOR FOR SAVING ELECTRIC POWER ON SHIPS
DESCRIPTION
It is a system for saving electric power on ships (a propeller generator for producing electricity).
This invention has to do with the production of electricity in order to save electric power on a ship during the voyage. The purpose of the invention is to produce electricity for the needs of the ship more economically.
The invention under consideration has to do with a variable pitch screw, which is fixed next to the propeller and the rudder of the ship, in order to take advantage of the hydrodynamics of the dead water created by the propeller of the ship. So far, this hydrodynamics of the dead water created by the propeller of a ship during its sailing was unexploited.
The advantages of this invention include exactly the fact that we take advantage of the hydrodynamics of the dead water created by the propeller of a ship in order to produce electricity for the necessary consumption of the ship at a low cost.
According to this invention, this is achieved by fixing a variable pitch screw next to the rudder of the ship, where the dead water created by its propeller give thrust to the blades of the variable pitch screw and, by means of axles, cause the revolving of the generator producing electricity.
The above mentioned invention is described below with the aid of an example and with reference to the attached drawing. The drawing (1) shows the stern part of a ship. The drawing (2) shows the propeller of the ship, whereas the drawing (3) shows the rudder of the ship. The drawing (4) presents the variable pitch screw, which is fixed next to the rudder of the ship and is supported upon a supporting base, drawing (5), the blades of which are given thrust by the dead water created by the propeller of the ship and, by means of axles and gears, drawing (6), transmit the motion to the generator, drawing (7).
The moving of the blades of the screw, drawing (4), is done by means of a hydraulic mechanism, drawing (8), depending on the necessary electricity consumption. Drawing (5) shows the supporting base inside which there are fixed the vertical axle transmitting the motion from the variable pitch screw to the generator, drawing (7), as well as the tubes of the hydraulic system, drawing (8), for changing the incline of the screw blades, drawing (4).
In drawing (6), the purpose of the gears is to increase the rotation from the vertical axle so that the size of the generator can be decreased, drawing (7).
In drawing (7), one can see the electricity producing generator, where motion is transmitted by means of gears and axles, drawing (6), of the variable pitch screw, drawing (4); this generator is connected to the electric panel, drawing (9), by means of cables.
5
In drawing (9), one can see the electric panel that includes control instruments and a safety device and has the purpose of connecting the generator, drawing (7), to the areas of the ship where electricity is consumed. Additionally, it is connected to the hydraulic mechanism, ιo drawing (8), so that the motion of the blades of the variable pitch screw, drawing (4), is adjusted according to the necessary electricity consumption. During the operation of this system, the blades of the screw, drawing (4), remain at a vertical position so that they do not influence the function of the ship.
4.5
Drawing (10) includes the horizontal axle, the gears that transmit the motion to the vertical axle, drawing (6), and the hydraulic mechanism for changing the position of the screw blades, drawing (4).
20 This invention is being used and produces results when the ship is moving during the voyage.
Claims
It is a system for saving electricity on a ship (a propeller driven generator for producing electricity) which is made up of a variable pitch screw (4) that is fixed at the stern part of the ship behind the rudder in the same straight line, and is supported upon a supporting base (5) and is revolved by of the dead water created by the propeller; by means of axles and gears (6) and (10) as well as of the hydraulic mechanism (8) it transmits the motion to the generator (7) which produces electric power without consuming any fuel, and the adjustment of the electricity produced, and as a result the variability of the pitch, is accomplished by means of an electric panel (9) and a hydraulic mechanism (8) depending on the given necessary electricity consumption of the ship.
