La presente invención se refiere a un colector, destinado a formar parte de una instalación de evacuación de aguas residuales, concretamente constituyendo el terminal de Ia parte de Ia instalación correspondiente al usuario o cliente, es decir como elemento de conexión de dicha red particular a Ia red general del alcantarillado público.The present invention relates to a collector, intended to be part of a wastewater evacuation installation, specifically constituting the terminal of the part of the installation corresponding to the user or customer, that is, as a connection element of said particular network to the general public sewer network.
El objeto de Ia invención es conseguir un colector antiparasitario, que ofreciendo una óptimas prestaciones como tal elemento colector, es decir en Io que a Ia evacuación de aguas residuales se refiere, actúe además como elemento antiparasitario, estableciendo una barrera a cucarachas y cualquier otro tipo de insectos, a roedores, etc.The object of the invention is to achieve an antiparasitic collector, which offers optimum performance as such a collector element, that is to say that in which the wastewater evacuation is referred to, it also acts as an antiparasitic element, establishing a barrier to cockroaches and any other type from insects, to rodents, etc.
El colector ofrece las dimensiones de cualquier colector convencional, de manera que puede ser fácilmente instalado en una red de eliminación de aguas residuales, por cuanto que se ajusta dimensionalmente a las medidas estandarizadas en este ámbito.The collector offers the dimensions of any conventional collector, so that it can be easily installed in a sewage disposal network, since it adjusts dimensionally to the standardized measures in this area.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, Ia red de alcantarillado público de cualquier ciudad constituye un habitat muy particular en el que viven diferentes tipos de insectos, en particular cucarachas, así como roedores y otros animales.As is known, the public sewer network of any city constitutes a very particular habitat in which different types live of insects, particularly cockroaches, as well as rodents and other animals.
El problema radica fundamentalmente en que dichos animales, en especial las cucarachas, llegan con facilidad a las viviendas u otros edificios conectados a dicha red de alcantarillado, utilizando para ello las propias tuberías de Ia red particular en los momentos en los que no circula agua por las mismas.The problem lies mainly in the fact that said animals, especially cockroaches, easily reach homes or other buildings connected to said sewerage network, using the pipes of the particular network at that time when water does not circulate through the same.
Hasta el momento actual Ia solución a esta problema consiste en Ia utilización de venenos insecticidas, Io que además de no conseguirUntil now the solution to this problem consists in the use of insecticidal poisons, which in addition to not getting
Ia erradicación de los mismos, supone una contaminación del medio ambiente, actuando dichos venenos de forma no selectiva, es decir afectando a otros animales que no son nocivos para el hombre, como por ejemplo las especies que habitan las aguas a las que finalmente van a desembocar los residuos contaminados, a pesar de haber sido tratados en depuradoras, donde se consigue Ia descomposición de Ia materia orgánica, pero no Ia eliminación de tales venenos.The eradication of the same, implies a contamination of the environment, acting these poisons in a non-selective way, that is to say affecting other animals that are not harmful to man, such as for example the species that inhabit the waters to which they will finally drain contaminated waste, despite having been treated in treatment plants, where the decomposition of organic matter is achieved, but not the elimination of such poisons.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El colector antiparasitario que Ia invención propone resuelve de forma plenamente satisfactoria Ia problemática anteriormente expuesta, permitiendo conseguir unos resultados mucho mas efectivos y selectivos.The antiparasitic collector that the invention proposes solves in a fully satisfactory way the problem described above, allowing to achieve much more effective and selective results.
Para ello y de forma mas concreta dicho colector basa su funcionalidad en Ia muerte de dichos parásitos por electrocutación, estableciendo en el punto de conexión entre Ia red de alcantarillado y cada instalación particular que desemboca en la misma, una alta tensión eléctrica, del orden de varios miles de voltios, de manera que cualquier parásito de los citados, como por ejemplo una cucaracha o un ratón, cuando pasa a través del colector sufre una descarga eléctrica que provoca su muerte instantánea.For this, and more specifically, said collector bases its functionality on the death of said parasites by electrocution, establishing at the connection point between the sewer network and each particular installation that flows into it, a high electrical voltage, of the order of several thousand volts, so that any parasite of those mentioned, such as a cockroach or a mouse, when it passes through the collector it suffers an electric shock that causes its instant death.
Específicamente el colector consiste en una especie de manguito dotado de cuellos de conexión debidamente normalizados, manguito en cuyo interior se establece al menos un electrodo anular, al que se va a aplicar Ia citada alta tensión, alimentado por un microprocesador, asistido por una fuente de alimentación y que controla un circuito de pulsos que, a través de un transformador, convierte Ia tensión de red primero en baja tensión (de 12 a 24 V), para dotar al dispositivo de Ia debida seguridad, y posteriormente a una tensión del orden de 3.500 V en los electrodos, para electrocutación de los parásitos.Specifically, the collector consists of a kind of sleeve provided with duly standardized connection necks, sleeve inside which at least one annular electrode is established, to which the said high voltage is to be applied, fed by a microprocessor, assisted by a source of supply and that controls a pulse circuit that, through a transformer, converts the mains voltage first to low voltage (from 12 to 24 V), to provide the device with adequate safety, and then to a voltage of the order of 3,500 V on the electrodes, for electrocution of parasites.
De acuerdo con otra de las características de Ia invención, el o los electrodos anulares de alta tensión quedan enmarcados por un anillo de entrada y un anillo de salida, ambos conectados a tierra, actuantes como elementos de seguridad.According to another of the characteristics of the invention, the high voltage annular electrode (s) are framed by an input ring and an output ring, both connected to ground, acting as safety elements.
Se ha previsto también Ia existencia de un sensor de presencia de agua a Ia entrada del colector, de manera que el electrodo anular de alta tensión resulte inoperante mientras se produce una descarga de agua en Ia instalación particular, para evitar derivaciones indeseadas.The existence of a water presence sensor at the collector inlet is also provided, so that the high voltage annular electrode is inoperative while a water discharge occurs in the particular installation, to avoid unwanted shunts.
La correspondiente unidad de control se encuentra alojada en una caja de mecanismos, exterior al colector propiamente dicho y debidamente fijada al mismo, caja en Ia que se establece también un interruptor de encendido para puesta en funcionamiento del aparato.The corresponding control unit is housed in a mechanism box, outside the collector itself and duly attached to it, a box in which an ignition switch is also established to put the device into operation.
Se consigue de esta manera una barrera eléctrica al paso de insectos y roedores, que prácticamente no consume energía mas que cuando se produce Ia descarga sobre alguno de estos animales, y con un consumo, prácticamente despreciable, de diodos led que señalizan tanto Ia situación operativa correcta del circuito como algún fallo en el mismo, así como también las descargas de alta tensión cuando éstas se producen.In this way, an electrical barrier to the passage of insects and rodents is achieved, which practically does not consume energy more than when the discharge occurs on any of these animals, and with a practically negligible consumption of LEDs that signal both The correct operating situation of the circuit as a fault in it, as well as high voltage discharges when they occur.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A Ia vista de las figuras reseñadas, y en especial de Ia figura 1 , puede observarse como el colector antiparasitario que se preconiza está constituido a partir de un manguito o colector propiamente dicho (1), a base de tres piezas, una intermedia y cilindrica que se corresponde con Ia propia referencia (1), y otras dos extremas (2-2'), que se acoplan y fijan de manera estanca a Ia pieza intermedia (1) y que constituyen estrangulaciones rematadas en cuellos (3) de dimensiones normalizadas, para su intercalación en Ia conducción de agua residual de que se trate, siendo todas estas piezas de PVC u otro material similar, definiéndose en Ia zona media del colector un ensanchamiento para Ia ubicación de al menos un electrodo anular (4), que va a estar sometido a alta tensión, y que al paso de uno de los parásitos citados va a provocar Ia descarga que provoque Ia muerte del mismo, o al menos un rechazo que haga imposible su acceso a Ia zona protegida.In view of the figures outlined, and in particular of Figure 1, it can be seen how the recommended antiparasitic manifold is constituted from a sleeve or manifold proper (1), based on three pieces, an intermediate and cylindrical which corresponds to the reference itself (1), and two other extremes (2-2 '), which are tightly attached and fixed to the intermediate piece (1) and that constitute strangulations topped on necks (3) of standardized dimensions , for its intercalation in the conduction of wastewater in question, all these pieces of PVC or other similar material being defined, in the middle area of the collector defining a widening for the location of at least one annular electrode (4), which is going to be subject to high voltage, and that the passage of one of the parasites mentioned will cause the discharge that causes the death of the same, or at least a rejection that makes it impossible to access the protected area.
Para Ia alimentación del electrodo (4), el colector incorpora un circuito alojado en una caja de mecanismos eléctricos (5), fijada lateralmente al casquillo (1) a Ia que acceden el cable (6) de alimentación eléctrica, con Ia tensión de red de 220 V en alterna, a través de un interruptor general de encendido (7), suministrándose así energía a una fuente de alimentación (8) capaz de transformar Ia tensión alterna de red en baja tensión continua, concretamente con salidas (9 y 10) respectivamente a 5 y 12 V.For the feeding of the electrode (4), the collector incorporates a circuit housed in an electrical mechanism box (5), fixed laterally to the socket (1) to which the power supply cable (6) accesses, with the mains voltage of 220 V in alternating, through a general ignition switch (7), thus supplying power to a power source (8) capable of transforming the alternating mains voltage into low continuous voltage, specifically with outputs (9 and 10) respectively at 5 and 12 V.
La salida (9) de 5 V se utiliza para alimentar (9') a un microprocesador (10), que controla a un circuito de pulsos (11) que a su vez recibe tensión (12) a través de Ia salida (12') de Ia fuente de alimentación (8), y convierte los 12 V suministrados por dicha fuente (8), con Ia colaboración de un transformador (13), en los 3.500 V previstos para el electrodo (4).The output (9) of 5 V is used to feed (9 ') to a microprocessor (10), which controls a pulse circuit (11) that in turn receives voltage (12) through the output (12' ) of the power supply (8), and converts the 12 V supplied by said source (8), with the collaboration of a transformer (13), into the 3,500 V provided for the electrode (4).
Dado que el cuerpo (1 , 2-2') del colector es de naturaleza plástica y consecuentemente es aislante, se ha previsto que el electrodo (4) quede enmarcado por dos anillos de puesta a tierra (14-14').Since the body (1, 2-2 ') of the collector is of a plastic nature and consequently is insulating, it is provided that the electrode (4) is framed by two earthing rings (14-14').
Como complemento de Ia estructura descrita y aguas arriba con respecto al electrodo (4) y a los anillos de puesta a tierra (14-14'), e! colector incorpora un sensor de agua (15), cuya función es anular funcionalmente el sistema cuando circula agua por el colector con el objeto de evitar que se produzca Ia descarga del electrodo (4) debido a Ia naturaleza electroconductora del agua.As a complement to the structure described and upstream with respect to the electrode (4) and the grounding rings (14-14 '), e! collector incorporates a water sensor (15), whose function is to functionally cancel the system when water circulates through the collector with the in order to avoid the discharge of the electrode (4) due to the electroconductive nature of the water.
Pues bien, este sensor (15) suministra información a un acondicionador (16), alimentado igualmente a través de Ia fuente (8) y que actúa sobre el microprocesador (10), para que éste provoque una situación de inoperancia para el circuito de pulsos (11) en tanto esté pasando agua a través del colector.Well, this sensor (15) provides information to a conditioner (16), also fed through the source (8) and acting on the microprocessor (10), so that it causes an inoperative situation for the pulse circuit (11) as long as water is passing through the collector.
Solo resta señalar por último Ia presencia de diodos luminiscentes señalizadores (17) alimentados también a expensas de las ordenes del microprocedsador (10), uno de color rojo señalizador de Ia existencia de un fallo en el sistema, otro de color verde que señaliza que el sistema opera correctamente, y finalmente un tercero blanco, que indica que se está produciendo una descarga de alta tensión en el electrodo (4). It only remains to indicate finally the presence of signaling light emitting diodes (17) also fed at the expense of the orders of the microprocessor (10), one red signaling the existence of a fault in the system, another of green color indicating that the The system operates correctly, and finally a white third, which indicates that a high voltage discharge is occurring in the electrode (4).
