Description

The invention relates to the field of energy engineering, in particular to energy drives, and can be used as a power unit for water or rail transport.

Known power plant electric drive [1], which contains a synchronous motor with a rotatable working mechanism, as well as a control system.

The disadvantage of [1] is that it performs one executive function for one mechanism it brings.

Known multifunctional power plant [2], which consists of a complex: internal combustion engine (ICE) with a gearbox for switching the speed of the driven working mechanism on the shaft.

The disadvantage of [2] is that there is no possibility of multifunctionality of the rotational parameters for the executive mechanical unit.

The closest to the essence of the claimed invention, the prototype is a multifunctional power plant [3], which consists of a complex: an internal combustion engine (ICE) with a drive on the shaft of an electric machine used as an electric energy generator and electric heat pump and also a control system .

The disadvantage of the prototype [3] is the lack of interchangeability and complementarity of the functions of the components of the power unit.

A device [D1] of an energy drive is known, consisting of an electric motor with a coupling, which is supplemented by a second mover and an engine.

A device [D2] is known, in which the electric motor is connected to the actuator by a clutch and the second engine is an internal combustion engine. However, D1 and D2 are not without drawbacks.

The aim of the invention is the multifunctionality of the parameters and the complementarity of the functions of the power components of the energy drive.

The goal is achieved in that the energy drive device consists of an electric motor connected by a coupling to the first actuator, supplemented by a second internal combustion engine (ICE) and a second actuator, the motor shaft with a clutch and a first actuator and a shaft of a second internal combustion engine and a second actuator are located on the same axis, while the motor shaft is made with a hollow space, and the shaft of the second internal combustion engine is placed in an removed hollow space of the shaft of the first electric motor, equipped with bearings at the ends, the clutch of the first electric motor located on the side of its actuator consists of the first and second coupling halves, which consist of a gear pair of gears, the first coupling half is located on the outer circumference of the hollow shaft, and the second coupling half for coupling the actuator also consists of a gear, while the aforementioned first and second coupling halves of the gear pair are located They are located in an oil tank on an additional support stand, which in turn also contains a support bearing on an additional extension of the shaft of the second engine in the direction of its actuator.

The essence of the invention is illustrated in the drawing, where: 1 - the first actuator; 2 - electric motor; 3 - second actuator; 4 - ICE; 5 - a hollow shaft of an electric motor coupled to a first actuator; 6 - an additional support column with an oil tank, containing a coupling sleeve from a first and second gear pair of coupling halves, a bearing for the shaft; 7 - the shaft of the second actuator associated with the internal combustion engine; 8 - support stand; 9 - coupling.

The device operates as follows: the energy drive device consists of two actuators with different rotational parameters.

The first actuator 1 is driven by the first electric motor 2 (for example, a synchronous motor with frequency control of revolutions), the second actuator 3 is driven by the second motor 4, which can be an internal combustion engine (ICE). Engines 2 and 4, respectively, their actuators 1 and 3, are placed on the same axis, which becomes possible, since the hollow shaft 5 of the electric motor 2, the coupling with the aforementioned shaft of the electric motor 2 and its thrust bearings on an additional support column 6, as well as the shaft of the actuator 1 are made with a hollow space in which the shaft of the second actuator 7 is placed with several extensions and with bearings at the ends of each extension, at the outputs of the shafts 5 and 7, inside the actuator 1, pre 8 will provide the second support strut respectively with bearings for the shafts 5 and 7, for withdrawing from it (5) is connected to the shaft 7, the shaft of the second actuator 3 through the connecting sleeve 9 that is also provided for connection of the output shaft 7 of the second 4 engine.

Engines 2 and 4 can be controlled both from one command post and from an individual command post of each engine, and it is controlled both by the number of revolutions and by their direction, exclusive for each individually.

The technical and economic effect of using the proposed solution lies in the fact that the location in one axis of the engines, mainly for use on surface and submarines to drive propellers in one axis, as well as the drive of mechanical units located on railway vehicles. Moreover, choosing the parameters of the phase shift from one actuator relative to another, a decrease in the resulting emitted sound from the operation of the whole power plant is achieved, due to the diffraction of sound waves emitted from the first and second, or vice versa, actuators. At the same time, the executive functions of the mechanical unit increase from the variety of combinations of the parameters of the first relative to the second actuators.

An example of the multifunctionality of an energy drive is a situation when it is necessary to accelerate the acceleration (speed) of the rotational moment of the energy unit or abruptly stop it, which is achieved by a combination, combination, of rotational parameters acting in one axis from each installation. And in an emergency situation with power supply in the power unit (in the object of using a technical solution), for example, in a submarine, the first electric motor 2, the synchronous electric motor is switched to electric generator mode, while taking part of the mechanical energy from the second engine 4, through mechanical gears - couplings, from shaft 7 to shaft 5, with most of the energy remaining on the shaft of the engine 4 to fulfill its direct function - to preserve the buoyancy of the vessel.

In the described case, the proposed technical solution allows providing consumers with emergency armor with electric power and preserving the buoyancy of the vessel in emergency mode.
