USSR №395303, MCL. VS 9/02. Rescue boat. Application No. 1498218/27-11 from 14.12.70, publ. 28.08.73. Bull. No. 35). Device to ensure its progress may be a steam generator with a working injector and a starting mechanism, the steam-engine propeller and trossoblochnoy management system, and to improve the efficiency and duration to paragaster through pneumatic valve with a valve is connected the supply tank with the reagent, and the nozzle of parageneratorov connected with the valve through a throttle valve and the supply line of the reagent installed in the hydraulic accumulator and the hydraulic pump, kinematically connected with a drive motor (see A.S. USSR №288580, MCL. VS 9/02. The emergency turn lifeboats. Application No. 1318081/27-11 from 07.04.69, publ. 03.12.70. Bull. No. 36).

The disadvantage of this boat is the complexity and the limited time of operation of the device to ensure its progress.

Also known synchronous generator of electric current in which the stator consists of the frame, coils, cores, windings and panel findings and housing - welded cast steel. Packages of the stator core is assembled from separate electrical steel sheets coated with an insulating varnish, all three phases of the stator winding and zero point are displayed on the bus. Salient-pole generator rotor consists of a shaft, frame and cores, which are winding and soothing. The core of the rotor is assembled from individual steel sheets, sealed in package. Traverse slip rings mounted on the flange bearing shield with roller and ball bearing, a fan; an edge for lifting; pole and the rotor of the generator initial start-up or other excitation system - independent, with self-excitation or mixed (see the book: Lakin B.C. Marine electric stations and systems. - M.: Transport, 1982, s-26).

The disadvantage of this generator is the need for an external drive that requires additional energy, which limits its ability to ensure the progress of the Autonomous floating tools.

The exclusion of external drive and constant production of electric power by the generator due to the energy of the waves when you swing them floating means in the displacement forces of gravity freely suspended statically unbalanced rotor or stator relative to the paired them is the commutator and the rotor is the main task of this patent application.

In the proposed application for the invention the problem is solved by equipping the boats with generators of new designs and variants of their installation, in which the generator containing a rotor and a stator with a common longitudinal axis located horizontally, and having a core, the coil, the excitation system and removal of the received electric current, is freely mounted a rotor or suspended on its axis stator, whose centers of mass are made eccentric offset relative to the longitudinal axis of their rotation, and to increase the eccentricity of the rotor or the stator may be an additional cargo and/or grooves and/or holes, which can be introduced material with a density greater than the surrounding material, or one or some of the coils and their cores can be excluded, or cores with coils placed asymmetrically or odd number greater than three, and pair them with a rotor or a stator fixed in the boat, with the possibility of oscillations waves, the generators can be installed in the front rows or coaxial to each other and to the perception of fluctuations in the waves acting on the boat in mutually perpendicular directions, such generators can be installed front and coaxial, including staggered, or frontal and axial rows in the distinctions of the different combinations, including in a checkerboard pattern, and to allow vibrations in three mutually planes rotors or stators can be mounted or suspended from the horizontal rotary platform, placed in the boat with the possibility of free rotation around its vertical axis, while on the platform and the adjacent portions of the boat can be performed cores with coils and excitation system, which ensure the generation of electric current, and the rotors and stators can be mounted or suspended from the platform in several rows and tiers, while indirect use of boats associated with the possibility of its generators of electric power in the course and swing on the waves of the vessel on which it is installed, to which the generator or associated battery pack supplied with current deflecting devices are protected from the ingress of moisture.

The structural design of the proposed generators, their variants and their positioning on the floating tool shown in the drawings.

Figure 1 shows the boat 1 with the device to ensure its progress, consisting of the lead screw 2, and a drive motor 3 with the battery pack 4 and the generator of electric current 5 containing the stator 6 and the rotor (armature) 7 with the General longitudinal axis of the O_inlocated horizontally. This state is attached to the plate 8 to the boat, while the rotor is in it is free from the drive device, with the ability to swing around its axis at an angle of ±α from acting on the boat waves, for which the center of mass About_mmade eccentric offset from the axis of rotation, and to increase the eccentricity e_pon the shaft 9 of the rotor fixed additional cargo 10, which may be a rechargeable battery. Thus, the generator produces an electric current forward and reverse directions, which can be either divided into flows with mixing them to the same phase and to ensure the battery used to drive movement of a drive motor, and/or heating, or cooling and lighting boat, or bypassing the battery, follow these steps directly, if the frequency of change of flow direction (the natural frequency of the pulses) will be multiplied semiconductor or other devices.

Figure 2 shows ways to increase eccentric offset e_pthe weight of the rotor, which is possible when performing in his skeleton 11 holes 12 and/or groove 13 in the shaft 9 and/or the frame 11 (version 1), and for the further increase of the eccentricity e_p(version 2) - make the holes and/or grooves on the opposite side of the rotor along the longitudinal and radial axes and fill their heavier material (i.e. higher density), with the exception of one of the field windings 14 (version 3), including core 15 together (version 4), or run odd number of cores with windings (version 5), or fasten inside the housing on the shaft instead of the fan (because the heat mode of operation of the generator does not require its use) asymmetric load 16 (version 6) and other

Figure 3 shows the development of options for the installation of generators 5 by increasing their number, placed along the axis of the boat 1 front rows and perceiving motion from the bow to the stern (version 1) and/or in series to each other and perceiving rolling (version 2), and to reduce the total length of the shafts 9 are attached to each other using couplings or clamps 17 with the installation of the stator 6 in the boat 1 on a common plate 18. In this interim generators excitation winding of the rotor is replaced by a total of 19, which in subsequent shafts of the generators are through holes for cable routing, and the ends of the shafts 9 can be cut or shortened. For all these rotor shaft can be made General, and for reducing the overall length of the Assembly intermediate bearing shields 20 and the fan 21 can be excluded. You may also combine the front and coaxial installations for the perception of pitch in two directions.

Figure 4 shows the boat 1 with a device to enable it to move the, consisting of lead screw 2, and a drive motor 3 with the battery pack 4 and the generator of electric current 5 containing the stator 6 and the rotor (armature) 7 with the General longitudinal axis of the O_inlocated horizontally. When the rotor 7 secured to the uprights 22 of the plate 23 to the boat, to its shaft 9 is freely suspended from the stator 6 with the ability to swing around its axis at an angle of ±α from the action on the boat waves, for which the center of mass About_mmade eccentric offset from the axis of rotation due to the asymmetric shape of the housing 24 and to increase the eccentricity e_cit may be additionally secured cargo, which can be a battery pack, and to limit the sector's swing stator can be made the stops 25. Thus, the generator produces an electric current forward and reverse directions, which can be either divided into flows with mixing them to the same phase and to ensure the battery life of the batteries used to drive movement of a drive motor and/or for heating or cooling and lighting boat, or bypassing the battery, follow these steps directly, if the frequency of change of flow direction (the natural frequency of the pulses of electric current produced by the generator) will be multiplied semiconductor or other devices

Figure 5 shows the options for increasing the eccentric offset e_cthe mass of the stator due to the performance in the case of 24 holes 26 and/or grooves 27 in the longitudinal (version 1) and/or radial direction, and to further enhance the e_with- make holes and grooves on the opposite side of the bed stator and filling them heavier (i.e. with a large proportion) material (2), and/or the housing 24 asymmetric thickness (version 3), and/or when the frame 27 asymmetric thickness (version 4).

Figure 6 shows the development of options for the installation of generators 5 due to the increase of their number to be placed on the boat 1 front rows on the rack 22 on a common frame 28 along its axis and perceiving rocking the boat from the bow to the stern (version 1) and/or on the racks 22 and the common core 28 in a row one behind the other, and perceiving aft rocking (version 2), and to reduce the total length of the shaft 9 of the rotor are connected to each other by couplings or clamps 17. In this case, all intermediate generators excitation replaced by a total of 19, which in subsequent shafts are made through holes for cable routing, and the ends of the shafts 9 can be removed or shortened. For all these rotor shaft 7 can be made General, and for reducing the total length of the construction of the intermediate bearing shields 0 and the fan 21 can be excluded. To limit the sector's swing stator 6 can be performed by the stops 25. It is also possible any combination of front and coaxial installations of generators, including rows of staggered, for the perception of the pitching of the boat in both directions.

Further development of the structures of the devices to ensure the progress of the boats and their positioning is associated with perceptual pitching of the boat in different directions.

Figure 7 shows the further development of the proposed installations of generators for any of the above versions.

Their distinctive feature is the placement of the generators 5, which is freely suspended statically unbalanced rotor 7 or stators 6 on the horizontal rotary platform 29 installed in the boat 1 (version 1, 2) or suspended from the roof 30 (versions 3 and 4), the thrust bearings 31, which further ensures their turn from the action of waves in the direction of the more massive parts of the generators. While the platform itself and the adjacent part of the boat may have a winding rotor 32 and the stator 33 types. All other structural and support elements 22 generators are similar to the previous versions, is shown in figure 1...6. This design provides the ability to turn generators and removal of current from the motion of its rotors and stators when the action is under the waves on the boat at any angle.

On Fig shows the development of the previous designs of the generator and how to install them in the boat due to its multi-tiered layout.

Their main difference is the placement of 2 or more generators 5 with freely suspended statically unbalanced rotor 7 and/or the stator 6 on the horizontal rotary platform 29 is installed on the ceiling 34 of the thrust bearings 31 on the top and bottom (version 1), while both these platforms and the adjacent part of the boat may have a winding rotor 32 and the stator 33 types and systems of their excitement and removing the produced electric current. Tiered layout generators possible on supports 22 on top of each other (version 2) and/or their combinations with the previous version, including a checkerboard pattern. The same options of a multi-level layout and their combinations are available for all of the generators 5 and their positioning.

Indirect use of all the variants of the boat is connected with the possibility of their generators of electric power in the course and rocking on the waves of the vessel on which they are installed, for which the generator or connected batteries supplied with current deflecting device 35 with a flanged connectors 36, protected from the ingress of moisture, through which boats are temporarily connected to the system is IU the supply vessel.

The remaining structural elements of the generators and their installation is similar to previous versions, is shown in figure 1...7.

The combination of these signs as shown in figure 1...8 performances boats with devices to ensure their progress and options installing the generators allows to characterize it as a technical solution, which is new and not obvious from the underlying technology. Their manufacturing is possible in real industrial production, as designs of boats similar to the known, and the generators are different from the base run only statically unbalanced rotors or stators by performing them in the slots and holes, or exclusion of the windings and cores, or the installation of additional cargo, or an asymmetric shape of the hull and the frame of the stator. More complex is the manufacture of boats with horizontally installed rotating platform generators with fixed stators or rotors of generators statically unbalanced paired them with rotors or stators, however, it is also possible in the conditions of modern industrial production. With all new designs of generators and their installation on boats are a development of the previous versions, consequential from each other, ensure that Ecevit the unity of purpose of the proposed application for the invention. Thus, it is possible to classify all proposed in this application of technical solutions as a device that meets all the features of the invention.

All of the proposed execution of the generators and their installation in the boat when the oscillation waves allow us to produce an electric current due to the motion of the rotors and stators relative to each other in one, two or three mutually perpendicular directions, which provides a positive effect from their use.

Real options offered generators are possible in any range develop capacity and standard sizes, which facilitates their selection, design and manufacture, however, the choice of the cross section of the conductors of the coils and windings is changed due to the decrease in the speed of rotors or stators, based on the actual number of oscillations of floating funds waves, usually constituting a value from 6 to 12 times per minute, when the sector oscillations α=±15° brings them to a conditional number 1...2 full rpm.

For example, for the original ship synchronous generator SG-200, which develops 200 kW when the number of revolutions per minute n=500, in the case of swings at angle α=±15° (1/12 of the total turnover) at an average frequency of side swings the boat 6 times per minute (ν=0.1 Hz) and 2 its reruns for one swing power and N_nso what will be the value (1)

However, you can change the parameters reproducing the electric current of the windings, in particular the cross section of their transaction and its length (number of coils), because the power of N_gthe generator is determined by the dependence (2)

where µ_about- magnetic constant,

μ is the relative magnetic permeability of the medium,

n is the number of coils per unit length of the winding,

I - electrical current,

V - volume of the excitation winding,

ν is the frequency of rotation.

Therefore, decreasing the rotor speed from 500 to 1 revolution per minute and under other equal conditions for parameters µ_about, µ, n, I, V providing the power required will depend on the number of turns n. Because they need to be put in the old section of the windings of the generator, then to the immutability of the original structure must be adequate reduction of the cross section of the conductor. But this way, at a constant electric field E leads to an increase of the current density j and limited electrical conductivity γ or resistivity ρ=1/γ of the conductor is determined by Ohm's law (3)

Thus, in the absence of the phenomenon of superconductivity in the windings of the generator, the current density will increase with decreasing cross-section of the conductor due to the behavior of the solutions of tension E, determined by the dependence (4):

where σ is the surface density of electric charges q on the conductor with an outer diameter d:

Then when the underlying value of the q and other conditions being equal, the reduction of diameter d will result in the same increase in density σ, and with it - the same increase in E and j, which are unfavorable for the operation of the generator.

To eliminate this drawback, the power rewound generator is advisable to increase from 0.4 to 20 kW, or 50 times, which is ensured by increasing the number of turns in 50 times and reduce them in section 7.07 times and with the same decrease in current in 7,07 time. Then provided constant q, d, σ and j that will not lead to the deterioration of working conditions of the generator, and the use of superconductivity increases its power. With this growing power of 20 kW is an acceptable value for the stroke of the lifeboats, because it is provided at its virtually unlimited range.

The achievement of technical and economic indicators for the proposed technical solution is not necessary, as it ensures the salvation of human lives, but the cost of producing them close to the cost of the equipment and rescue boats other power plants, such as diesel top is Yves to ensure their progress, and on the ship in the course enables you to replace at least one diesel generator, providing direct economic effect of exceptions on it costs, reduce fuel consumption, reduce the occupied volume and mass, which can be used for cargo or equipment of the vessel other devices. Although the magnitude of this effect depends on the specific conditions, but it can reach 10...100 thousand$ per year for each vessel. Given that such ships may be more than 100 thousand, the net effect will be from 1 to 10 billion$.

The above data confirms the feasibility of wide application of the proposed devices, their positioning and application.
