Abstract

The present application is about a mechanical device that recovers kinetic energy in order to power up machines, being especially applicable to electric energy's generators, and it is comprised by an electric engine (1), that powers up a flywheel with specific characteristics (2) which will power up another similar flywheel (3) by the use of sprockets between them. That allows the development and accumulation of kinetic energy that after being converted to mechanical energy will enable its axis to obtain the necessary torque to power up an electric generator (4) when engaged or coupled.

Description

DESCRIPTION

MECHANICAL DEVICE TO RECOVER KINETIC ENERGY IN ORDER TO POWER UP MACHINES

Technical area of the invention

Currently there is a strong disposition towards the production of electricity through renewable energies using various systems of resources' captation that renew themselves constantly in a sustainable way.

The flywheels are the oldest form of energy storage technology, without however being a way to obtain sustainable renewable energy and directly responsible for its exploitation .

Status of technique

The flywheels are elements that are used in most motors that maintain movement, by use of inertia, when there is variation of the engine torque that moves them. Currently there is energy storage's systems that rely on magnetically levitated flywheels, in which the energy is stored under the form of the flywheel's rotation kinetic energy. These flywheels are used in situations in which there is variation in the search of short term's electric energy and with immediate answer, whereby, the flywheel rapidly loses speed and consequently energy, demonstrating a lack of sustainability .

Summary of the invention

The present invention is about a mechanical device that recovers kinetic energy and converts it in mechanical energy in order to power up machines, being especially applicable to electric energy's generators, whose behaviour is based on flywheels that by turning through the use of an electric motor capable of beating inertia and acting continuously allows specific acceleration and kinetic energy development that after being converted to mechanical energy can power up an electric generator with sustainable output.

The device of the present invention includes two flywheels that are supported in shafts, that are connected in parallel between one another with sprockets. One of them is powered up by an electric engine that supports in its shaft a flywheel and a sprocket, which engages in another wheel that spins the shaft of a second flywheel, providing it with its rotation and torque and allowing it to develop and amass kinetic energy. After being converted to mechanical energy, it can give away part of its energy, even if it compromises some speed, and so, giving away continuously its torque, that can be taken advantaged by a machine or an electric energy's generator .

Through this, it is possible to multiply the torque of the electric engine's shaft and generate kinetic energy that after being converted to mechanical energy can be used as a source of sustainable renewable energy.

So, the object device of the present invention is characterized in that it is a mechanical device for recovering kinetic energy and converting it into mechanical energy, being especially applicable to power up electric generators .

The present invention is next described in detail, without limitation and by way of example, in a form of preferred embodiment, represented in the attached drawings, in which:

- fig. 1.1 is a simplified and schematic representation of an embodiment of the device according to the invention.

- fig. 1.2 is a schematic cut of the mentioned device from fig. 1.1. Description of the preferred embodiment

By making reference to the figures, the preferred embodiment of the invention will now be described, in which the device is consisted of a set of organs represented in the mentioned figures, assembled as described below.

The support structure (5) includes two flywheels (2, 3), connected in parallel between one another by two sprockets (8, 9) . The flywheel (2) is powered up by an electric engine (1) that will also tangentially transmit its movement through the sprockets (8, 9) to another flywheel (3) that is supported in the shaft (7) , which is part of the power shaft that allows to power up an electric generator (4) . The flywheels (2, 3) are similar and possess a hollow and cylindrical shape that supports in its interior a conical recipient (10) that has its vertex pointing downwards vertically. The conical recipient (10) contains a granulated liquid or solid mass (11) that moves freely and conditioned to the inner surface of the recipient.

The operation of this equipment is based on the rotation movement of an electric engine (1) of residual power required to overcome the inertia at rest, that can be powered with a battery (not represented) that is recharged with the device own output or by exterior power. It powers up a flywheel (2) with specific characteristics that will allow to develop kinetic energy and increase the torque on its axis, which in its turn due to the tangential gear of sprockets (8, 9) will transmit a certain rotation and torque to another flywheel (3) with similar characteristics, supported in the shaft (7) . Then, it will also develop a certain kinetic energy and increase the torque of its shaft (7) , which is part of the power shaft that will power up the generator (4) . The hollow and cylindrical shape of these flywheels contribute to their performance, supporting in their interior a conical recipient with its vertex pointing downwards vertically that contains a granulated liquid or solid mass which moves freely and conditioned to the inner surface of the interior. That allows that when in rotation, the mass rises causing a levitation force on the flywheel attenuating its weight and, on the other hand, allowing the increase of the mean radius of its mass, which allows the development of more kinetic energy on the flywheels (2, 3) .

The possibility of modification and setting of all of these parameters allows this device to be scalable, when it comes to size and to the use of more similar flywheels (2, 3), supported in new shafts and with the respective sprockets geared to one of the already existing sprockets.
