Description

INSTALACIÓN PARA LA PRODUCCIÓN DE ENERGÍA ELÉCTRICA A PARTIR  INSTALLATION FOR THE PRODUCTION OF ELECTRICAL ENERGY FROM
DE ANIMALES DE TIRO  OF SHOT ANIMALS
La presente invención se refiere a una instalación para la producción continua y estable de energía eléctrica a partir de animales de tiro. The present invention relates to an installation for the continuous and stable production of electrical energy from draft animals.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Son conocidas instalaciones para la producción de energía eléctrica a partir de animales de tiro que comprenden un generador para la producción de energía eléctrica y medios de accionamiento de dicho generador a partir de la fuerza procedente de dichos animales de tiro. Installations for the production of electrical energy from draft animals comprising a generator for the production of electrical energy and means for actuating said generator from the force from said draft animals are known.
La patente EP1416615 describe una de dichas instalaciones en la que los medios de accionamiento de dicho generador incluyen un mecanismo de tracción asociado a dichos animales de tiro que comprende unos brazos de arrastre que actúan sobre el rotor del generador eléctrico a través de un dispositivo convertidor/multiplicador que adapta el par del mecanismo de tracción al giro del rotor del generador eléctrico.  The patent EP1416615 describes one of said installations in which the driving means of said generator include a traction mechanism associated with said draft animals comprising drag arms that act on the rotor of the electric generator through a converter device / multiplier that adapts the torque of the traction mechanism to the rotation of the rotor of the electric generator.
Las instalaciones como la descrita en la patente EP1416615 son particularmente interesantes para la producción de energía eléctrica en áreas rurales del tercer mundo que carecen de suministro a través de red eléctrica.  Installations such as that described in patent EP1416615 are particularly interesting for the production of electrical energy in rural areas of the third world that lack supply through an electrical network.
Sin embargo, se ha observado que dichas instalaciones presentan el inconveniente de que no proporcionan una energía eléctrica continua y estable, ya que la velocidad a la que se desplazan los animales de tiro nunca es continua ni regular. Por este motivo, estas instalaciones deben emplear baterías y/o inversores que adecúen la electricidad para su consumo con la consiguiente pérdida de rendimiento que ello supone, además del incremento en costes, mantenimiento y reciclaje de baterías.  However, it has been observed that these installations have the disadvantage that they do not provide a continuous and stable electric energy, since the speed at which the draft animals move is never continuous or regular. For this reason, these facilities must use batteries and / or inverters that adapt the electricity for consumption with the consequent loss of performance that this entails, in addition to the increase in costs, maintenance and recycling of batteries.
Otro inconveniente que presentan las instalaciones conocidas hasta el momento reside en el hecho de que, para hacer funcionar el rotor del generador eléctrico a partir de las bajas revoluciones de los animales de tiro, incluyen dispositivos mecánicos convertidores y/o multiplicadores que están sometidos a unas elevadas fuerzas de tracción que los hacen muy sensibles a los paros bruscos o cambios de velocidad de los animales de tiro. Por otro lado, la utilización de excesivos componentes mecánicos también supone una pérdida de energía por rozamiento, así como un coste de mantenimiento elevado. DESCRIPCIÓN DE LA INVENCIÓN Another drawback presented by the facilities known so far lies in the fact that, to operate the rotor of the electric generator from the low revolutions of the draft animals, they include mechanical converting devices and / or multipliers that are subjected to high tensile forces that make them very sensitive to sudden stops or speed changes of draft animals. On the other hand, the use of excessive mechanical components also involves a loss of energy due to friction, as well as a high maintenance cost. DESCRIPTION OF THE INVENTION
El objetivo de la presente invención es resolver los inconvenientes mencionados, desarrollando una instalación para la producción de energía eléctrica a partir de animales de tiro que presenta la ventaja de que posibilita una obtención continua y estable de energía eléctrica, lista para el consumo directo, y de que tiene un bajo coste de mantenimiento y una larga vida útil. The objective of the present invention is to solve the aforementioned drawbacks, developing an installation for the production of electric energy from draft animals that has the advantage that it allows a continuous and stable obtaining of electric energy, ready for direct consumption, and It has a low maintenance cost and a long service life.
De acuerdo con este objetivo, la presente invención proporciona instalación para la producción de energía eléctrica a partir de animales de tiro, que comprende un generador para la producción de energía eléctrica y medios de accionamiento de dicho generador a partir de la fuerza procedente de dichos animales de tiro, y se caracteriza por el hecho de que dichos medios de accionamiento comprenden un sistema hidráulico que incluye un motor hidráulico que acciona dicho generador y un grupo de presión configurado para proporcionar a dicho motor hidráulico un caudal y una presión de fluido sustancialmente constantes, incluyendo dicho grupo de presión una bomba hidráulica que es accionada por un mecanismo de tracción asociado a dichos animales de tiro.  In accordance with this objective, the present invention provides installation for the production of electrical energy from draft animals, which comprises a generator for the production of electrical energy and actuation means of said generator from the force from said animals. drawing, and is characterized by the fact that said drive means comprise a hydraulic system that includes a hydraulic motor that drives said generator and a pressure group configured to provide said hydraulic motor with a substantially constant flow rate and fluid pressure, said pressure group including a hydraulic pump that is driven by a traction mechanism associated with said draft animals.
Al ser accionado el rotor del generador a través de un sistema hidráulico, la velocidad y la fuerza final que recibe el rotor de dicho generador puede ser controlada de un modo muy fácil y eficaz, sin necesidad de recurrir a un mecanismo de tracción provisto de dispositivos convertidores y/o multiplicadores complejos que dificultan el funcionamiento y el mantenimiento de la instalación.  When the generator rotor is driven through a hydraulic system, the speed and final force that the rotor of said generator receives can be controlled in a very easy and efficient way, without the need for a traction mechanism provided with devices complex converters and / or multipliers that hinder the operation and maintenance of the installation.
En la presente invención, el mecanismo de tracción es tan sólo responsable de accionar la bomba hidráulica del grupo de presión que está configurado para proporcionar a dicho motor hidráulico un caudal y una presión de fluido sustancialmente constante, por lo que dicho mecanismo de tracción puede tener un diseño muy simple y un número muy reducido de componentes.  In the present invention, the traction mechanism is solely responsible for driving the hydraulic pump of the pressure group that is configured to provide said hydraulic motor with a substantially constant flow and fluid pressure, whereby said traction mechanism can have a very simple design and a very small number of components.
Por otro lado, al ser accionado el generador eléctrico por un motor hidráulico que recibe una caudal y una presión de fluido sustancialmente constantes, la energía eléctrica que produce el generador es estable y continua, no siendo necesario emplear ningún tipo de baterías y/o conversores para adaptar la electricidad producida al consumo directo.  On the other hand, when the electric generator is driven by a hydraulic motor that receives a substantially constant flow and fluid pressure, the electric energy produced by the generator is stable and continuous, and it is not necessary to use any type of batteries and / or converters to adapt the electricity produced to direct consumption.
Preferiblemente, dicha bomba hidráulica es una bomba configurada para trabajar a un régimen de revoluciones igual o inferior a 50 revoluciones por minuto (rpm), por ejemplo, una bomba configurada para trabajar a un régimen de revoluciones comprendido entre 10 y 45 revoluciones por minuto (rpm). A estas revoluciones, la bomba deberá ser capaz de suministrar la presión y caudal de fluido necesario para alimentar a un acumulador que a su vez suministra el fluido hidráulico estable, tanto en presión como en caudal, al motor hidráulico que mueve el alternador produciendo energía eléctrica apta para el consumo directo. Preferably, said hydraulic pump is a pump configured to work at a speed of less than 50 revolutions per minute (rpm), for example, a pump configured to work at a speed between 10 and 45 revolutions per minute (rpm). At these revolutions, the pump must be able to supply the pressure and fluid flow necessary to feed an accumulator that in turn supplies the stable hydraulic fluid, both in pressure and in flow, to the hydraulic motor that moves the alternator producing electrical energy Suitable for direct consumption.
La bomba de bajas revoluciones presenta la ventaja de que se adapta a la velocidad de trabajo de los animales de tiro, lo que confiere estabilidad al sistema hidráulico que acciona el generador.  The low speed pump has the advantage that it adapts to the working speed of draft animals, which gives stability to the hydraulic system that drives the generator.
Otra vez preferiblemente, dicho grupo de presión incluye un acumulador hidráulico configurado para almacenar una determinada cantidad de fluido a presión procedente de dicha bomba hidráulica.  Again preferably, said pressure group includes a hydraulic accumulator configured to store a certain amount of pressurized fluid from said hydraulic pump.
Este acumulador actúa como reserva de energía, permitiendo que el sistema hidráulico funcione durante un tiempo determinado sin recibir la fuerza motriz animal. Por ejemplo, el acumulador puede configurarse para actuar como reserva de energía durante un tiempo de trabajo superior a 30 segundos.  This accumulator acts as an energy reserve, allowing the hydraulic system to run for a certain time without receiving the animal motive force. For example, the accumulator can be configured to act as a power reserve for a working time exceeding 30 seconds.
De este modo, se consigue un proceso de trabajo cómodo de los animales y del operario que lo controla, ya que dichos animales pueden parar, por ejemplo, para descansar, o reducir su velocidad de desplazamiento.  In this way, a comfortable working process of the animals and the operator controlling it is achieved, since said animals can stop, for example, to rest, or reduce their travel speed.
Ventajosamente, dicho acumulador incluye un detector de presión provisto de un sistema de aviso acústico y/o luminoso.  Advantageously, said accumulator includes a pressure detector provided with an acoustic and / or luminous warning system.
De este modo, el operario puede controlar eficazmente la velocidad de los animales, posibilitando en todo momento un ritmo de trabajo que mantenga una presión suficiente dentro del acumulador que garantice el caudal y presión constantes al motor hidráulico.  In this way, the operator can effectively control the speed of the animals, allowing at all times a working rhythm that maintains sufficient pressure inside the accumulator that guarantees constant flow and pressure to the hydraulic motor.
Otra vez ventajosamente, dicho grupo de presión incluye un regulador de presión y caudal de fluido procedente de dicho acumulador hidráulico, estando configurado dicho regulador para proporcionar a dicho motor hidráulico un caudal y presión de fluido sustancialmente constantes.  Again advantageously, said pressure group includes a fluid pressure and flow regulator from said hydraulic accumulator, said regulator being configured to provide said hydraulic motor with a substantially constant fluid flow and pressure.
El regulador de presión y caudal es un elemento imprescindible del sistema hidráulico que dosificará el flujo que necesita el motor a la presión prefijada para garantizar que el alternador o generador trabaje a revoluciones sustancialmente constantes que permitan la producción estable y continua de energía eléctrica lista para el consumo directo.  The pressure and flow regulator is an essential element of the hydraulic system that will dose the flow that the engine needs at the preset pressure to ensure that the alternator or generator works at substantially constant revolutions that allow the stable and continuous production of electrical energy ready for direct consumption
Según una realización preferida, dicho mecanismo de tracción incluye una rueda motriz y una pluralidad de brazos de arrastre de dicha rueda, siendo accionados dichos brazos de arrastre por la fuerza de tracción de dichos animales. According to a preferred embodiment, said traction mechanism includes a driving wheel and a plurality of driving arms of said wheel, being driven said trailing arms by the tensile force of said animals.
Dicha rueda motriz y dichos brazos de arrastre configuran un mecanismo a modo de noria de tiro que tiene como característica principal la tenencia de una gran fuerza de empuje.  Said driving wheel and said trailing arms form a mechanism as a ferris wheel that has as its main feature the possession of a large thrust force.
Preferiblemente, dicho mecanismo de tracción incluye un dispositivo multiplicador/conversor mecánico para elevar las revoluciones de dicha rueda motriz a las revoluciones de trabajo de la bomba hidráulica.  Preferably, said traction mechanism includes a mechanical multiplier / converter device for raising the revolutions of said driving wheel to the working revolutions of the hydraulic pump.
A diferencia de las instalaciones del estado de la técnica, este dispositivo multiplicador/conversor es muy simple ya que tan sólo es necesario que se adapte a las revoluciones de la bomba hidráulica.  Unlike the installations of the state of the art, this multiplier / converter device is very simple since it only needs to adapt to the revolutions of the hydraulic pump.
Preferiblemente, dicho dispositivo multiplicador/convertidor está unido al eje de la bomba hidráulica a través de un embrague que está configurado para acoplarse al eje de la bomba una vez que las revoluciones del eje de salida del dispositivo multiplicador hayan ascendido a un valor predeterminado para que los animales aprovechen la inercia de desplazamiento.  Preferably, said multiplier / converter device is attached to the axis of the hydraulic pump through a clutch that is configured to engage the pump shaft once the revolutions of the output shaft of the multiplier device have risen to a predetermined value so that Animals take advantage of the inertia of displacement.
De este modo, los animales pueden arrancar fácilmente hasta adquirir una inercia de desplazamiento.  In this way, animals can easily start up to acquire a displacement inertia.
Ventajosamente, dichos brazos de arrastre están unidos articulados, por uno de sus extremos, a dicha rueda motriz.  Advantageously, said trailing arms are connected articulated, by one of their ends, to said driving wheel.
De este modo, los brazos de arrastre pueden bascular con respecto a la rueda motriz para adaptarse a la altura de los animales de tiro.  In this way, the trailing arms can swing with respect to the driving wheel to adapt to the height of the draft animals.
Otra vez ventajosamente, dichos brazos de arrastre están unidos, por otro de sus extremos, a una rueda de apoyo provista de medios de regulación de altura.  Again advantageously, said drag arms are connected, at another end, to a support wheel provided with height adjustment means.
Esta rueda de apoyo proporciona una zona estable de anclaje para los animales que, además, puede adaptar-se en altura para garantizar que el gancho de tiro quede situado debajo del lomo y detrás del animal.  This support wheel provides a stable anchorage zone for animals that, in addition, can be adapted in height to ensure that the pull hook is located under the spine and behind the animal.

It is estimated that with this alternator model it is possible to produce electricity at 220 V and 50 Hz continuously, during approximate work cycles of between 3 and 5 hours.
Tal y como se ha comentado en la descripción de la invención, a diferencia de las instalaciones del estado de la técnica, en la presente instalación el mecanismo 1 de tracción es tan sólo responsable de accionar la bomba 5 hidráulica del grupo 6 de presión que está configurado para proporcionar al motor 7 hidráulico un caudal y presión de fluido sustancialmente constantes. Por lo tanto, dicho mecanismo 1 de tracción puede tener un diseño muy simple y un número muy reducido de componentes. As mentioned in the description of the invention, unlike the prior art installations, in the present installation the mechanism 1 traction is only responsible for driving the hydraulic pump 5 of the pressure group 6 which is configured to provide the hydraulic motor 7 with a substantially constant flow and fluid pressure. Therefore, said traction mechanism 1 can have a very simple design and a very small number of components.
En la realización que se describe, el mecanismo 1 de tracción incluye, además de la rueda 2 motriz y de los brazos 3 de arrastre de dicha rueda 2, un dispositivo 13 multiplicador/conversor mecánico (ver figura 5) para elevar las revoluciones de la rueda 2 motriz a las revoluciones de trabajo de la bomba 5. Este dispositivo 13 multiplicador/conversor recibe el movimiento de la rueda 2 motriz a través de un cable 14 o cadena de transmisión asociada a una segunda rueda o piñón conducido 15.  In the described embodiment, the traction mechanism 1 includes, in addition to the drive wheel 2 and the drive arms 3 of said wheel 2, a mechanical multiplier / converter device 13 (see figure 5) for raising the revolutions of the drive wheel 2 at the working revolutions of the pump 5. This multiplier / converter device 13 receives the movement of the drive wheel 2 through a cable 14 or transmission chain associated with a second driven wheel or pinion 15.
El mencionado dispositivo 13 se ha previsto con una relación de multiplicación aproximada de 1/10 que permitirá ascender hasta 20 rpm las 2 rpm que se estima dará la rueda 2 motriz al ser accionada por los animales 4, a través de unos brazos 3 de arrastre de aproximadamente 3 m de longitud.  The aforementioned device 13 is provided with an approximate multiplication ratio of 1/10 that will allow up to 20 rpm the 2 rpm that is estimated to give the driving wheel 2 when driven by the animals 4, through drag arms 3 about 3 m long.
En la realización que se describe, el dispositivo 13 multiplicador está unido al eje de la bomba 5 hidráulica a través de un embrague (no representado) que está configurado para acoplarse al eje de la bomba 5 una vez que las revoluciones del eje de salida del dispositivo 13 multiplicador han ascendido a un valor predeterminado (por ejemplo, 7 a 10 rpm) en el que los animales ya llevan una inercia de desplazamiento. El mencionado embrague puede ser de tipo mecánico, o de tipo centrífugo, estando provisto en este último caso de una válvula de control para abrir progresivamente el circuito de fluido.  In the described embodiment, the multiplier device 13 is connected to the axis of the hydraulic pump 5 through a clutch (not shown) that is configured to engage the axis of the pump 5 once the output shaft revolutions of the 13 multiplier device has risen to a predetermined value (for example, 7 to 10 rpm) in which the animals already carry a displacement inertia. Said clutch can be of mechanical type, or of centrifugal type, in the latter case being provided with a control valve to progressively open the fluid circuit.
Volviendo ahora a la rueda 2 motriz y a los brazos 3 de arrastre del mecanismo 1 de tracción, estos elementos están dispuestos de modo que configuran un mecanismo a modo de noria de tiro que tiene como características principales la tenencia de una gran fuerza de empuje y un lento desplazamiento.  Turning now to the driving wheel 2 and the trailing arms 3 of the traction mechanism 1, these elements are arranged so that they configure a mechanism as a ferris wheel which has as main characteristics the possession of a large thrust force and a slow travel
Tal y como puede verse en las figuras 1 a 3, en este mecanismo de noria, la rueda 2 motriz ocupa una posición central y está reforzada por unos rodillos 16 que la centran. Los brazos 3 de arrastre están unidos articulados, por un extremo 3a, a la rueda 2 motriz y, por otro extremo 3b, a una rueda 17 de apoyo provista de un sistema 18 de regulación en altura. Los mismos brazos 3 poseen cada uno un gancho 19 al que está unido el animal 4 de tiro a través de un yugo 20 doble.  As can be seen in Figures 1 to 3, in this ferris wheel mechanism, the driving wheel 2 occupies a central position and is reinforced by rollers 16 that center it. The drive arms 3 are connected articulated, at one end 3a, to the driving wheel 2 and, at the other end 3b, to a support wheel 17 provided with a height adjustment system 18. The same arms 3 each have a hook 19 to which the draft animal 4 is attached through a double yoke 20.
La figura 4 muestra un detalle de un brazo 3 de arrastre en el que se aprecia la rueda 17 de apoyo y el sistema 18 de tuerca de unión roscada que permite regular la altura del brazo 3 para asegurar que el gancho 19 de tiro queda situado debajo del lomo del animal. Figure 4 shows a detail of a drag arm 3 in which it can be seen the support wheel 17 and the threaded union nut system 18 which allows the height of the arm 3 to be adjusted to ensure that the draw hook 19 is located under the animal's back.
El mencionado sistema 18 de tuerca de unión y la articulación de los brazos 3 de arrastre permite que la noria de tiro pueda adaptarse a varios tipos de animales de tiro, como por ejemplo, bueyes, caballos, camellos, etc ..  The aforementioned union nut system 18 and the articulation of the drag arms 3 allows the draft wheel to be adapted to various types of draft animals, such as oxen, horses, camels, etc.
En la realización que se describe, la rueda 2 motriz y todos los componentes del sistema 11 hidráulico están fijados sobre un chasis 21.  In the described embodiment, the drive wheel 2 and all the components of the hydraulic system 11 are fixed on a chassis 21.
A continuación se describe el proceso de producción de energía eléctrica mediante la instalación de la realización descrita.  Next, the process of producing electricity is described by installing the described embodiment.
Una vez que los animales 4 están atados a los ganchos 19 de los brazos 3 de arrastre, un operario regulará el sistema 18 de tuerca de unión roscada para asegurar que dichos ganchos 19 quedan situados por debajo del lomo de los animales 4.  Once the animals 4 are attached to the hooks 19 of the drag arms 3, an operator will regulate the threaded joint nut system 18 to ensure that said hooks 19 are located below the back of the animals 4.
A continuación, el mismo operario se encargará de hacer mover a los animales 4 para accionar la rueda 2 motriz que está asociada al dispositivo 13 multiplicador/convertidor, a través del cable o cadena 14 y una segunda rueda o piñón 15.  Next, the same operator will be in charge of moving the animals 4 to drive the driving wheel 2 that is associated with the multiplier / converter device 13, through the cable or chain 14 and a second wheel or pinion 15.
Al inicio del desplazamiento y para facilitar el arranque de los animales 4, el eje de salida del dispositivo 13 multiplicador/convertidor estará desacoplado del eje de la bomba 5 hidráulica, gracias a un embrague asociado a dicho dispositivo 13 y a dicha bomba 5. Una vez que los animales adquieren la velocidad idónea de desplazamiento y las revoluciones del eje de salida del dispositivo 13 multiplicador/convertidor ascienden a un valor cercano a 10 rpm, el mencionado embrague acoplará el eje de salida de dicho dispositivo 13 al eje de la bomba 5 hidráulica para que dicha bomba 5 empiece a impulsar fluido a presión hacia los acumuladores 9 y hacia el motor 7 hidráulico que alimenta el generador 8 eléctrico.  At the beginning of the movement and to facilitate the starting of the animals 4, the output shaft of the multiplier / converter device 13 will be disengaged from the axis of the hydraulic pump 5, thanks to a clutch associated with said device 13 and said pump 5. Once that the animals acquire the ideal displacement speed and the revolutions of the output shaft of the multiplier / converter device 13 amount to a value close to 10 rpm, said clutch will couple the output shaft of said device 13 to the axis of the hydraulic pump 5 so that said pump 5 begins to drive pressurized fluid towards the accumulators 9 and towards the hydraulic motor 7 that feeds the electric generator 8.
En los acumuladores 9 se almacenará fluido a una presión comprendida entre 40 bar y 80 bar. Esta reserva de energía será suficiente para permitir que la instalación pueda funcionar durante unos segundos sin necesidad de que los animales trabajen. Esto es necesario para conseguir un proceso de trabajo cómodo de los animales 4 y del operario que los controla.  In the accumulators 9, fluid will be stored at a pressure between 40 bar and 80 bar. This reserve of energy will be sufficient to allow the installation to work for a few seconds without the need for animals to work. This is necessary to achieve a comfortable working process for animals 4 and the operator who controls them.
Tal y como se ha comentado en la descripción de la invención, al objeto de facilitar el control del proceso, la instalación incluirá un detector de presión de fluido de los acumuladores 9 provisto de un sistema de aviso acústico y/o luminoso. De este modo, el operario podrá verificar que la velocidad de los animales 4 se encuentra dentro del rango de trabajo de la instalación. As mentioned in the description of the invention, in order to facilitate process control, the installation will include a fluid pressure detector of the accumulators 9 provided with an acoustic and / or light warning system. In this way, the operator can verify that the speed of the animals 4 is within the working range of the installation.

Para conseguirlo, el motor 7 hidráulico recibirá una cantidad y presión de fluido constante que será controlada por un regulador 10 hidráulico que se ha diseñado para proporcionar unos 20 1/min de fluido a 40 bar. De este modo, se asegurará la producción continua y estable de energía eléctrica a 220 V y 50 Hz, lista para el consumo directo, sin necesidad de utilizar baterías o inversores.  The installation described is designed to be able to transmit a torque of 10.25 Nm, at 700 rpm, to a generation unit (0.75 kW alternator), uninterruptedly, during 3 and 5 hour work cycles . To achieve this, the hydraulic motor 7 will receive a constant amount and pressure of fluid that will be controlled by a hydraulic regulator 10 that is designed to provide about 20 1 / min of fluid at 40 bar. In this way, the continuous and stable production of electricity at 220 V and 50 Hz will be ensured, ready for direct consumption, without using batteries or inverters.
