    DESCRIPTION

    ENERGY RECOVERY SYSTEM
    OBJECT OF THE INVENTION 5

    The present invention relates to a system for recovering the energy generated in pedaling, whose obvious purpose is to take advantage of the energy produced in the pedaling activity of an exercise bike, or of a normal bicycle arranged on a support static, so that energy can be harnessed by transforming into electrical energy. 10

    More specifically, the object of the invention is to recover the energy lost in exercise bicycles, when performing physical exercise by users, as well as promoting citizen awareness and awareness about the energy demand of our daily activities, all without having to use batteries or electrical storage means 15.

    The field or technical sector in which the invention is applicable, is the production and generation of energy, as well as the final consumption of this, etc.
     twenty BACKGROUND OF THE INVENTION

    Nowadays, the concern for the environment, sport and of course the cost of energy is growing, so it would be very useful and desirable to be able to use the energy lost in certain physical activities, specifically in the one produced 25 for pedaling on exercise bikes.

    Although the inclusion of alternators or dynamos on bicycles for the generation of electrical energy is known, this solution is applied to the electrical elements that participate in them, so that it cannot be used for other applications or external areas. 30

    Today there are facilities in which several static bicycles equipped with the aforementioned equipment are grouped in a circuit, which feed a set of batteries or accumulators, in order to take advantage of said generated energy.
     35
    The problem with this type of installation is that the batteries to be used are expensive, bulky and need constant maintenance, so it would be desirable to have other means to take advantage of such generated energy.
    DESCRIPTION OF THE INVENTION 5

    The system that is recommended, part of the structure known and previously referred to, in which a series of stationary bicycles established in a specific place or place participate, in which said bicycles are combined to drive corresponding motors / generators, so that the energy generated electricity can be used for external uses, so that the system aims to create a space where leisure, awareness about energy efficiency, solidarity and physical activity are combined, exploring the use of one's own energy produced by pedaling, motivated by leisure activities, or to obtain the economic performance of our pedaling, even being able to invest it in social projects associated with the project. fifteen

    Obviously, the creation of a space in which, through exercise bicycles, energy is generated, motivates users to perform a physical activity based on pedaling so that the user himself is the engine and generator of energy, accounting for this and taking advantage directly in the own electrical installation of the gym or premises in which 20 bicycles are installed.

    It is evident that the benefit generated, for example, in a company in which the system of the invention is applicable, reverts to the users through different forms created, both for the awareness of energy saving and production, and for the support economic to 25 social projects proposed, both by the promoters and by the user.

    In addition to the use of stationary bicycles, the system allows the use of normal bicycles arranged on a fixed support, which allows to always take advantage of an existing product in the market for power generation, accounting for its use as a data bank to perform consumption and production statistics.

    From this conventional structuring, the invention focuses on the use of asynchronous motors / generators of friction rings, associated with the axis of rotation of the bicycle cranks, so that by using this type of motors / generators, no se 35
    require energy storage circuits, with their corresponding accumulators or batteries, so that the energy can be used directly in the facility where the bicycles are established.

    The asynchronous motor is used as a generator connected to the alternating current electrical network, 5 injecting a voltage through its friction rings, from a variable frequency oscillator controlled in voltage, such that, when rotating due to pedaling, it functions as an asynchronous generator . The speed of rotation of the motor shaft and the vectors of voltage and intensity in the asynchronous motor are also measured. Known, in this way, the power generated and the speed of rotation the resistant torque is obtained. Said resistant torque is compared with the torque setpoint given by a potentiometer or the like. The error signal obtained varies the frequency of the voltage injected into the friction rings, so that the resistant torque is determined by the setpoint.

    The regulation task is entrusted to a microcontroller. It obtains the power generated from the measurement of the vectors of network voltage and intensity generated. The speed is deduced from a measuring device in solidarity with the motor shaft.

    The output is an electrical signal that is applied to the variable frequency generator.
     twenty
    In this way, the motor acts as a generator, so that the energy generated by pedaling is alternating current and in phase with the grid voltage. That is, by forcing the motor to spin through pedaling, this instead of receiving alternating current by the stator, will generate current through it and to the electrical installation of the system site, so that at the end the The effect would be that a part of the electricity expense of the place would cease to be consumed from the conventional electricity grid.

    In short, the system of the invention establishes or offers an innovative space, different from the transformation of human energy into electrical energy, achieving an awareness environment that also enables the financing of the project, as well as a personal economic benefit, in addition to the already received in the form of health, all in a way that does not necessarily result in greater savings by creating more efficient devices, but by making users more aware of their consumption, and this can be seen in campaigns such as water saving , which tries to raise awareness through numbers and statistics to consumers so that they become aware of the implications of their 35
    Actions.

    On the other hand, it is possible to say in relation to the environmental impact, that the underlying idea of the energy generation project through the exercise of pedaling, not because of the volume of it, but because of the activity used in the generation, still carries a Human physical activity 5 that allows us to reflect on the management of energy sources and the processes of energy training at a global level, so that the savings of consumer awareness is comparable to the energy, environmental and economic savings It has been caused in the garbage bag industry, since awareness campaigns cause people to realize the impact of their poor management, allowing a decrease in production costs and waste management in unparalleled percentages of media in the improvement in the manufacturing or recycling process of the bags themselves.

    The project in which the system of the invention will materialize, will in turn act as a center 15 for environmental awareness and as a starting point and shuttle for common base projects.

    Finally, to say that the service offered based on the system of the invention intends to create a new market for itself, which corresponds to the exploration of the use of human energy originated in pedaling to enjoy its applications and dedicate its production to different purposes, so that the public arises, although not exclusively, from the growing social awareness about the importance of the environment, sport and the user as a consumer in our social and collective well-being.
     25
    In short, an efficient, simple installation is achieved, without the need for energy storage means, or constant maintenance, in which motors / generators of lower cost than DC motors participate, and in which the best use is made of energy, since it should not be transformed into alternating current for use, contrary to what happens with DC motors. 30
    DESCRIPTION OF THE DRAWINGS

    In order to complement the description that is going to be carried out below and in order to help a better understanding of the characteristics of the invention, the present report is attached 35
    Descriptive, forming an integral part of it, a single sheet of plans where illustrative and not limiting, the following has been represented:

    Figure 1.- Corresponds to a group of exercise bikes to whose bottom axles an alternator is connected whose output is connected to a common electrical point for electrical use 5.

    Figure 2.- Shows a block diagram of the elements that participate in the electrical system, including the motor / generator.
     10 PREFERRED EMBODIMENT OF THE INVENTION

    As can be seen in Figure 1, the system of the invention starts from the use of a plurality of static bicycles (1), so that the corresponding bottom bracket (2) of such a bicycle (1) is associated with a generator of electrical energy, so that the energy produced in the pedaling by a person is connected to the electrical network (4) of the installation, through the corresponding wiring (3), without the use of batteries or elements of accumulation

    To do this, more specifically, according to the concept presented above, as can be seen in Figure 2, the generator that is associated with the bottom bracket of each bicycle is materialized specifically in an asynchronous motor of friction rings (5 ), in which the stator (6) is connected to the mains (4) directly.
    For its part, the motor shaft and consequently its rotor (7) is connected by means of the corresponding transmission to the bicycle's bottom bracket. 25

    To said rotor (7), specifically to the friction ring system, a variable frequency oscillator (8) is connected around the grid frequency, which allows to vary the electric motor slip, irrespective of the mechanical speed and therefore the power generated by the engine. 30

    The microcontroller (9) measures the voltage and intensity vectors, by means of two devices (in the drawing, materialized as 10 and 11 respectively). From them and from the speed measurement, device materialized in the drawing as 12, the resistant torque is obtained. From its comparison with the desired one, set by a potentiometer or similar, the 35
    signal that attacking the variable frequency oscillator makes the resistant torque equal to the desired one.

    The information collected by this controller would be stored in a centralized database to be able to perform generation statistics, in addition to offering all types of applications to the user.

    The concept of the asynchronous friction ring generator is innovative because the energy generated by pedaling is generated in the form of alternating current and in phase with the energy received by the stator. That is, by forcing the motor to spin by pedaling, 10 instead of receiving alternating current through the stator, it would generate current through it and to the electrical installation of the room. The effect in the end would be that a part of the room's electrical expenditure would cease to be consumed from the conventional electricity grid since the electrical installation of the room would be injected with the generated energy.
     fifteen
    From this structuring an additional circuit is necessary that prevents the balance of generated energy from becoming positive. For this purpose, a switched resistive load managed by a microcontroller (12) is used, as indicated in the figure, according to the following process:
     twenty
    The switched load is represented as (15). The microcontroller (12) measures the voltage through the device (14) and the intensity through the device (13). Calculate with them the balance of generated power and act on the switched resistive load (15), so that said balance is always zero.
     25
    The same applies to the reactive power of which the engine is a consumer. This is supplied analogously by the switched capacitor (16). As a side effect, the device achieves a cos  = 1, (null consumption or reagent generation) with the consequent improvement in the electricity bill.
