Description

Die Erfindung betrifft eine Ver- und Entsorgungsvorrichtung für eine Sanitäreinrichtung in Fahrzeugen, umfassend einen Fundamentschacht, der sich im Einbauzustand von einem auf oder oberhalb der Terrainoberfläche angeordneten oberen Schachtende zu einem unterhalb der Terrainoberfläche angeordneten unteren Schachtende erstreckt, eine in dem Fundamentschacht verlaufende Frischwasserleitung, die im Bereich des unteren Schachtendes einen Frischwasseranschluss für eine Frischwassererdleitung aufweist.The invention relates to a supply and disposal device for a sanitary facility in vehicles, comprising a foundation shaft which, when installed, extends from an upper shaft end arranged on or above the terrain surface to a lower shaft end arranged below the terrain surface, a fresh water line running in the foundation shaft, which has a fresh water connection for a fresh water underground pipe in the area of the lower end of the shaft.

Versorgungseinrichtungen dieser Art werden dazu eingesetzt, um Fahrzeuge, die mit einer Sanitäreinrichtung ausgerüstet sind, mit Frisch- oder Trinkwasser zu versorgen und deren Abwasser zu entsorgen. Solche Fahrzeuge mit Sanitäreinrichtungen können beispielsweise Reisebusse, gleisgebundene Fahrzeuge oder Luftfahrzeuge sein.Supply facilities of this type are used to supply vehicles that are equipped with a sanitary facility with fresh or drinking water and to dispose of their waste water. Such vehicles with sanitary facilities can be, for example, coaches, track-bound vehicles or aircraft.

Auf Grund der hohen Mengen an bereitzustellendem Frischwasser und aufzunehmendem Abwasser sind mobile, also bewegliche, Versorgungseinrichtungen mit entsprechenden Flüssigkeitsbehältern nicht praktikabel und gut geeignet, obwohl durch solche mobilen Versorgungseinrichtungen sowohl die Zuordnung als auch die Variabilität solcher Versorgungseinrichtungen zu einem Fahrzeug vereinfacht würde und häufig Rangierbedarf, der demgegenüber bei stationären Versorgungsstationen notwendig ist, vermieden werden kann.Due to the large amounts of fresh water to be provided and waste water to be collected, mobile, i.e. mobile, supply facilities with corresponding liquid containers are not practicable and well suited, although such mobile supply facilities would simplify both the assignment and the variability of such supply facilities to a vehicle and often require shunting, which, on the other hand, is necessary in the case of stationary supply stations, can be avoided.

Stationäre Versorgungseinrichtungen können direkt an lokale Frischwasserleitungen und Abwasserleitungen angeschlossen werden und benötigen daher keinen Behälter zur Speicherung von Frischwasser und keinen Behälter zur Speicherung von Abwasser. Allerdings müssen, beispielsweise zur parallelen und effizienten Versorgung von mehreren gleisgebundenen Fahrzeugen, dann auch entsprechend mehrere stationäre Versorgungstationen bereitgestellt werden, die in entsprechender Beabstandung angeordnet sind, um die effiziente und parallele Versorgung durchführen zu können. Die Notwendigkeit, mehrere solche Versorgungsstationen bereitstellen zu müssen, übt grundsätzlich einen Kostendruck aus, der sich sowohl auf die Versorgungsvorrichtung an sich als auch auf deren Einrichtung, Installation und die laufenden Betriebskosten bezieht.Stationary utilities can be connected directly to local fresh water and sewer lines and therefore do not require a fresh water storage tank or a waste water storage tank. However, for example, for the parallel and efficient supply of several rail-bound vehicles, a corresponding number of stationary supply stations must then also be provided, which are arranged at an appropriate distance in order to be able to carry out the efficient and parallel supply. The necessity of having to provide several such supply stations basically exerts a cost pressure, which relates both to the supply device itself and to its set-up, installation and ongoing operating costs.

Für eine sichere Versorgung von Fahrzeugen mit Sanitäreinrichtungen ist ein ganzjähriger Betrieb der Versorgungsvorrichtung notwendig und folglich entsprechend zu gewährleisten. Insbesondere, weil mit der Versorgungsvorrichtung Frischwasser zugeführt und Abwasser abgeführt wird, besteht bei kalten Umgebungstemperaturen die Gefahr, dass der sichere Betrieb durch Eisbildung gestört oder verhindert wird oder dass infolge von Eisbildung Beschädigungen auftreten, welche den sicheren Betrieb stören oder verhindern kann.For a safe supply of vehicles with sanitary facilities, year-round operation of the supply device is necessary and must therefore be guaranteed accordingly. In particular, because the supply device is used to supply fresh water and drain waste water, there is a risk at cold ambient temperatures that safe operation will be disrupted or prevented by ice formation or that damage will occur as a result of ice formation, which could disrupt or prevent safe operation.

Die Wasserbefüllvorrichtung zeichnet sich dadurch aus, dass eine Spülaufnahmeöffnung bereitgestellt ist, welche zur Aufnahme des Wasserausgangsanschlusses ausgebildet und mit einer Spülwasserausgangsöffnung in Fluidverbindung steht, und dass die Steuerungseinheit ausgebildet ist, um die Ventilantriebsvorrichtung nach Ablauf eines vorbestimmten ersten Zeitintervalls anzusteuern zum Schalten des Absperrventils aus der geschlossenen in die geöffnete Stellung und die Ventilantriebsvorrichtung nach Ablauf eines an das erste Zeitintervall anschließenden zweiten Zeitintervalls anzusteuern zum Schalten des Absperrventils aus der geöffneten in die geschlossene Stellung.Out of DE 20 2014 003 274 U1 a water filling device for sanitary facilities in vehicles is known, comprising a water inlet connection, a water outlet connection, a connecting line that connects the water inlet connection to the water outlet connection for water passage, a shut-off valve, which is inserted into the connecting line, and can be switched between an open position and a closed position can, a valve drive device for actuating the shut-off valve from the open position to the closed position and vice versa, and a control unit which is coupled to the valve drive device in terms of signals and is designed to control the valve drive device. The water filling device is characterized in that a rinsing receiving opening is provided, which is designed to receive the water outlet connection and is in fluid communication with a rinsing water outlet opening, and that the control unit is designed to activate the valve drive device after a predetermined first time interval has elapsed in order to switch the shut-off valve out of the closed to the open position and to control the valve drive device after a second time interval following the first time interval to switch the shut-off valve from the open to the closed position.

Hierzu befindet sich eine Absaugeinrichtung in einem Schacht, der so zu einem Auslassstutzen des Tanks angeordnet ist, dass herabtropfende Flüssigkeit aufgefangen wird. Die Absaugeinrichtung selbst wird zum Absaugen aus dem Schacht herausgefahren, um sodann durch horizontales Verschieben mit dem Anschlussstutzen verbunden zu werden.Further revealed EP 0 404 170 A1 a device for sucking liquids from a tank located in a vehicle.

For this purpose, there is a suction device in a shaft which is arranged in relation to an outlet connection of the tank in such a way that dripping liquid is caught. The suction device itself is moved out of the shaft for suction, in order to then be connected to the connecting piece by moving it horizontally.

Vor dem Hintergrund besteht ein Bedarf für eine Versorgungsvorrichtung, welche eine ganzjährige Ver- und Entsorgung von Fahrzeugen mit Sanitäreinrichtungen gewährleistet, ohne hierbei die damit verbundenen Kosten für die Einrichtung, Herstellung und den Betrieb der Versorgungsvorrichtung in unwirtschaftlicher Weise zu erhöhen.Against this background, there is a need for a supply device that ensures year-round supply and disposal of vehicles with sanitary facilities without uneconomically increasing the associated costs for setting up, manufacturing and operating the supply device.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Versorgungsvorrichtung nach Anspruch 1.This object is achieved according to the invention by a supply device according to claim 1.

Erfindungsgemäß wird eine Versorgungsvorrichtung vorgeschlagen, die stationär installiert ist. Die Versorgungsvorrichtung weist einen Fundamentschacht auf, der als Fundamentrohr ausgebildet sein kann. Dieser Fundamentschacht dient einerseits der Aufnahme einer Frischwasserleitung und einer Abwasserleitung, kann darüber hinaus aber auch Fundamentierungsaufgaben übernehmen, beispielsweise um einen Mast, an dem die aus dem Fundamentschacht herauslaufenden Frischwasserleitungen und Abwasserleitungen geführt oder aufgehängt sind, beispielsweise als entsprechender Schlauch, stabil zu verankern. Der Fundamentschacht kann auch als Schutzrohr oder dergleichen ausgebildet sein und in oder an zusätzlichen, im Erdbereich vorbereiteten Fundamentierungskomponenten befestigt werden, beispielsweise kann ein zusätzlicher Betonring bereitgestellt werden, der die Verankerung und damit den sicheren Stand oberirdisch angeordneter Komponenten der Versorgungsvorrichtung erhöht.According to the invention, a supply device is proposed which is installed in a stationary manner. The supply device has a foundation shaft that can be designed as a foundation pipe. On the one hand, this foundation shaft serves to accommodate a fresh water line and a waste water line, but it can also take on foundation tasks, for example to stably anchor a mast on which the fresh water lines and waste water lines running out of the foundation shaft are guided or suspended, for example as a corresponding hose. The foundation shaft can also be designed as a protective tube or the like and fastened in or on additional foundation components prepared in the ground area, for example an additional concrete ring can be provided which increases the anchoring and thus the secure footing of components of the supply device arranged above ground.

Grundsätzlich weist die Versorgungvorrichtung eine Frischwasserleitung und eine Abwasserleitung auf. Diese Frischwasserleitung und Abwasserleitung können als Schlauchleitungen ausgeführt sein, ebenso sind Lösungen vorteilhaft, bei denen die Frischwasserleitung und die Abwasserleitung oder eine der beiden durch eine teilweise starre Rohrleitung und eine damit verbundene Schlauchleitung ausgeführt sind. Die Schlauchleitung verläuft dabei vollständig oder teilweise oberirdisch und dient insbesondere dazu, den Anschluss der Frischwasserleitung bzw. der Abwasserleitung an den Frischwasseranschluss bzw. den Abwasseranschluss des Fahrzeugs herzustellen. Es ist insbesondere bevorzugt, wenn die Frischwasserleitung und die Abwasserleitung einen oberirdisch als Schlauch ausgeführten Abschnitt jeweils aufweisen, der an einem Mast geführt ist, beispielsweise solcher Art, dass dieser als Schlauch ausgeführte Abschnitt mittels eines Zugelementes, das an dem Mast umgelenkt ist, befestigt ist und durch ein an dem Zugelement befestigtes Gegengewicht in eine eingezogene, kompakte Position gezogen wird und aus dieser Position zum Anschluss an einen Frischwasseranschluss bzw. Abwasseranschluss eines Fahrzeugs in eine operative Stellung ausgezogen werden kann.Basically, the supply device has a fresh water line and a waste water line. This fresh water line and waste water line can be designed as hose lines, solutions are also advantageous in which the fresh water line and the waste water line or one of the two are made of a partially rigid pipeline and a hose line connected to it. The hose line runs completely or partially above ground and is used in particular to connect the fresh water line or the waste water line to the fresh water connection or the waste water connection of the vehicle. It is particularly preferred if the fresh water line and the waste water line each have a section designed above ground as a hose, which is guided on a mast, for example in such a way that this section designed as a hose is fastened by means of a pulling element that is deflected on the mast and is drawn to a stowed, compact position by a counterweight attached to the tension member and can be extended from that position to an operative position for connection to a vehicle fresh water and waste water supply, respectively.

Erfindungsgemäß ist der Frischwasseranschluss, mit dem die Frischwasserleitung an eine Frischwassererdleitung angeschlossen werden kann, über eine Ventilvorrichtung bereitgestellt. Dies bedeutet, dass im Bereich des unteren Endes des Fundamentschachtes eine Ventilvorrichtung angeordnet ist, die vom Frischwasser durchströmt wird. Die Ventilvorrichtung kann über die an ihr ausgebildeten Anschlüsse direkt mit der Frischwassererdleitung und der Frischwasserleitung verbunden sein, jedoch können auch separate Verbindungsleitungsabschnitte vorgesehen sein, welche eine Verbindung zwischen der Ventilvorrichtung und der Frischwassererdleitung und/oder einer Verbindung zwischen der Ventilvorrichtung und der Frischwasserleitung herstellen.According to the invention, the fresh water connection, with which the fresh water line can be connected to a fresh water underground line, is provided via a valve device. This means that a valve device through which fresh water flows is arranged in the area of the lower end of the foundation shaft. The valve device can be connected directly to the fresh water ground line and the fresh water line via the connections formed on it, but separate connecting line sections can also be provided which establish a connection between the valve device and the fresh water ground line and/or a connection between the valve device and the fresh water line.

Die Ventilvorrichtung dient dazu, eine sichere Vermeidung von Frostschäden in der Frischwasserleitung zu erreichen. Zu diesem Zweck ist die Ventilvorrichtung in der Tiefe des Fundamentschachts angeordnet und kann dadurch in einem frostsicheren Bereich angeordnet werden. Die Ventilvorrichtung ermöglicht einerseits die Frischwasserzufuhr aus der Frischwassererdleitung in die Frischwasserleitung und damit die Befüllung eines Frischwassertanks eines Fahrzeugs mit Wasser, das über die Frischwassererdleitung der Versorgungsvorrichtung zugeführt wird. Neben dieser Funktion in einer Zuflussventilstellung ermöglicht die Ventilvorrichtung weiterhin die Entwässerung oder Belüftung der Frischwasserleitung in einer anderen Stellung, der Entwässerungsventilstellung. In dieser Entwässerungsventilstellung wird das Wasser, welches sich in der Frischwasserleitung befindet, über einen Frischwasserablaufanschluss abgeführt. Wenn die Entwässerungsventilstellung geschaltet ist, fließt somit Wasser aus der Frischwasserleitung entgegen der Richtung ab, mit der das Frischwasser bei Befüllung eines Frischwassertanks durch die Frischwasserleitung fließt. Die hierdurch erreichte Entfernung des Frischwassers bewirkt, dass keine Frostgefahr für die Frischwasserleitung besteht.The valve device serves to achieve reliable avoidance of frost damage in the fresh water line. For this purpose, the valve device is arranged in the depth of the foundation shaft and can thus be arranged in a frost-proof area. On the one hand, the valve device enables fresh water to be supplied from the fresh water underground line into the fresh water line and thus the filling of a fresh water tank of a vehicle with water that is supplied to the supply device via the fresh water underground line. In addition to this function in an inflow valve position, the valve device also allows the fresh water line to be drained or aerated in another position, the drain valve position. In this drainage valve position, the water that is in the fresh water line is discharged via a fresh water drain connection. When the drainage valve position is switched, water thus flows out of the fresh water line in the opposite direction to the direction in which the fresh water flows through the fresh water line when a fresh water tank is being filled. The removal of the fresh water achieved in this way means that there is no risk of frost for the fresh water line.

Das Frischwasser, welches in der Entwässerungsventilstellung abgeführt wird, kann einer speziell hierfür zusätzlich bereitgestellten zusätzlichen Entwässerungs-Abwassererdleitung zugeführt werden, es kann auch der Abwasserleitung oder der Abwassererdleitung zugeführt werden und es kann auch im Fundamentschacht selbst frei austreten und dort versickern.The fresh water, which is discharged in the drainage valve position, can be fed to an additional drainage underground sewage pipe provided especially for this purpose, it can also be fed to the sewage pipe or the sewage underground pipe and it can also escape freely in the foundation shaft itself and seep away there.

Durch die Anordnung der Ventilvorrichtung im unteren Bereich des Schachtes und die Möglichkeit, die Frischwasserleitung zu entwässern, wird die Gefahr einer Vereisung und von Frostschäden somit verhindert, ohne dass hierdurch nennenswerte zusätzliche Kosten im Betrieb, der Installation oder Herstellung der Versorgungsvorrichtung auftreten.By arranging the valve device in the lower area of the shaft and the possibility of draining the fresh water line, the risk of icing and frost damage is thus prevented without significant additional costs arising in the operation, installation or manufacture of the supply device.

Gemäß einer ersten bevorzugten Ausführungsform wird die Versorgungsvorrichtung fortgebildet durch ein mit der Ventilvorrichtung verbundenes mechanisches Betätigungselement, welches sich von der Ventilvorrichtung aus in Richtung des oberen Schachtendes erstreckt und einen Betätigungsabschnitt zur manuellen Betätigung der Ventilvorrichtung aufweist. Ein solches mechanische Betätigungselement ermöglicht die Betätigung der Ventilvorrichtung durch manuelle Betätigung, d.h. ohne zugeführte Energie, sondern durch reine Benutzerkraft. Das mechanische Betätigungselement kann zu diesem Zweck beispielsweise als Welle, Hebel, Zugstange oder Druckstange ausgeführt ein, um durch eine entsprechende Betätigung in Form einer Rotation, Verschwenkung, einer Zugkraft und/oder einer Druckkraft die Verstellung des Ventils von der Zuflussventilstellung in die Entwässerungsventilstellung und ggf. umgekehrt zu bewirken. Das mechanische Betätigungselement erstreckt sich zu diesem Zweck von der Ventilvorrichtung aus nach oben. Es kann insbesondere über die Terrainoberfläche hinaus sich erstrecken, um eine bequeme Betätigung an einem oberirdisch angeordneten Betätigungsabschnitt zu ermöglichen. Jedoch sind auch Lösungen anwendbar, bei denen sich das Betätigungselement unter der Terrainoberfläche befindet. Das Betätigungselement kann aus dem Fundamentschacht herausragen, beispielsweise nach oben hinaus sich über den Fundamentschacht hinaus erstrecken oder sich seitlich aus dem Fundamentschacht heraus erstrecken, um eine einfache Zugänglichkeit des Betätigungsabschnitts zu ermöglichen, der dann außerhalb des Fundamentschachts angeordnet sein kann. Grundsätzlich ist zu verstehen, dass das Betätigungselement durch eine einstückige Komponente gebildet sein kann, ebenso aber auch durch zwei oder mehr Komponenten, beispielsweise eine Welle, die über ein Winkelgetriebe mit einem Betätigungshandrad verbunden ist, oder dergleichen, gebildet werden kann.According to a first preferred embodiment, the supply device is developed by a mechanical actuating element connected to the valve device, which extends from the valve device in the direction of the upper shaft end and has an actuating section for manual actuation of the valve device. Such a mechanical actuating element enables the valve device to be actuated by manual actuation, ie without any energy being supplied, but by pure user power. For this purpose, the mechanical actuating element can be designed, for example, as a shaft, lever, pull rod or push rod, in order to be activated by a corresponding actuation in the form of rotation, pivoting, a tensile force and/or a compressive force to bring about the adjustment of the valve from the inflow valve position to the drain valve position and, if necessary, vice versa. For this purpose, the mechanical actuating element extends upwards from the valve device. In particular, it can extend beyond the terrain surface in order to enable convenient operation on an above-ground operating section. However, solutions are also applicable in which the actuating element is below the terrain surface. The actuating element can protrude from the foundation shaft, for example extend upwards beyond the foundation shaft or extend laterally out of the foundation shaft to enable easy access to the actuating section, which can then be arranged outside the foundation shaft. In principle, it should be understood that the actuating element can be formed by a one-piece component, but can also be formed by two or more components, for example a shaft that is connected to an actuating hand wheel via an angular gear, or the like.

Noch weiter ist es bevorzugt, wenn die Ventilvorrichtung ein 3/2-Wegeventil ist. Bei dieser Ausgestaltung weist die Ventilvorrichtung ein einziges Ventil auf, das über drei Anschlüsse verfügt und zwei explizite Ventilstellungen aufweist. Hiermit wird genau die Minimalfunktion, die die erfindungsgemäße Ventilvorrichtung aufweisen muss, erfüllt. Diese kompakte Ausgestaltung der Ventilvorrichtung ist bevorzugt, wenngleich auch andere Ausführungsformen, wie beispielsweise eine Ventilvorrichtung, die aus zwei 2/2-Wegeventile zusammengesetzt ist, die erfindungsgemäße Funktion erfüllen können. Grundsätzlich ist zu verstehen, dass die Ventilvorrichtung auch über zusätzliche Funktionalität verfügen kann, beispielsweise kann eine zusätzliche Ventilstellung oder ein zusätzlicher Ventilanschluss bereitgestellt sein, um zusätzliche Funktionen und Anschlussmöglichkeiten bereitzustellen.It is even more preferred if the valve device is a 3/2-way valve. In this configuration, the valve device has a single valve that has three connections and two explicit valve positions. In this way, the minimum function that the valve device according to the invention must have is fulfilled. This compact design of the valve device is preferred, although other embodiments, such as a valve device composed of two 2/2-way valves, can also fulfill the function according to the invention. In principle, it should be understood that the valve device can also have additional functionality, for example an additional valve position or an additional valve connection can be provided in order to provide additional functions and connection options.

Noch weiter ist es bevorzugt, wenn der Frischwasserablaufanschluss zur Verbindung mit einer zweiten Abwassererdleitung ausgebildet ist. Die zweite Abwassererdleitung ist hierbei neben der Abwassererdleitung, welche eingangs beschrieben wurde, bereitgestellt und kann beispielsweise zur schwerkraftbedingten Ableitung des Entwässerungsvolumens aus der Frischwasserleitung dienen. Die Bereitstellung einer getrennten, zweiten Abwassererdleitung weist den Vorteil auf, dass diese zweite Abwassererdleitung separat und getrennt von dem Abwasserleitungsnetz bereitgestellt werden kann, mit dem die Entsorgung des Abwassers über die Versorgungsvorrichtung ausgeführt wird. Dies ist in vielen Anwendungsfällen vorteilhaft, da hierdurch eine direkte Ankopplung der Frischwassererdleitung über die Ventilvorrichtung an die Abwasserleitung, die mit Schwarzwasser beaufschlagt ist, vermieden wird und hierdurch Hygienevorschriften erfüllt werden können, die andernfalls, wenn die Ventilvorrichtung direkt an eine schwarzwasserführende Abwasserleitung angeschlossen wäre, um das Entwässerungsvolumen aus Frischwasserleitung da herein abzuführen, gesonderte Sperrvorrichtungen benötigen würde, um eine Verkeimung des Frischwassernetzes zuverlässig zu verhindern.It is even more preferred if the fresh water drain connection is designed for connection to a second underground sewage pipe. The second underground sewage pipe is provided next to the underground sewage pipe, which was described at the outset, and can be used, for example, to divert the drainage volume from the fresh water pipe by gravity. The provision of a separate, second underground sewage pipe has the advantage that this second underground sewage pipe can be provided separately and separately from the sewage pipe network with which the disposal of the sewage is carried out via the supply device. This is advantageous in many applications, as this allows direct coupling of the fresh water underground line via the valve device to the waste water line, which is charged with black water. is avoided and thereby hygiene regulations can be met, which would otherwise require separate blocking devices to reliably prevent contamination of the fresh water network if the valve device were connected directly to a black water-carrying sewage pipe in order to drain the drainage volume from the fresh water pipe into it.

Noch weiter ist es bevorzugt, wenn die Abwasserleitung und der Anschluss an die Erdwasserleitung zur Absaugung des Abwassers mittels eines Unterdrucks ausgebildet sind. Gemäß dieser Ausführungsform sind die Abwasserleitungen und die Erdwasserleitung sowie der entsprechende Anschluss zwischen Abwasserleitung und Erdwasserleitung unterdruckfest ausgeführt, sodass eine Absaugung des Abwassers aus der Sanitäreinheit des Fahrzeugs mittels Unterdruck ermöglicht wird. Eine solche Absaugung, die über die Abwasserleitung und die Abwassererdleitung erfolgt, ist aus verschiedenen Gründen vorteilhaft. Zum einen wird die variable Einsetzbarkeit der Versorgungsvorrichtung erhöht, indem neben der Entfernung des Abwassers durch eine untere Öffnung des Abwassertanks auch eine Entfernung des Abwassers durch eine obere Öffnung des Abwassertanks möglich wird. Des Weiteren wird durch die unterdruckbeaufschlagte Absaugung eine Entwässerung der Abwasserleitung und somit eine Reduktion der Frostgefahr immanent bewirkt und hierdurch die Betriebssicherheit bei kalten Außentemperaturen gewährleistet. Grundsätzlich ist es vorteilhaft, die Abwassererdleitung mit einem Gefälle in Ablaufrichtung des Abwassers zu verlegen, auch wenn das Abwasser unterdruckbeaufschlagt abgeführt wird. Grundsätzlich ermöglicht die unterdruckbeaufschlagte Abfuhr des Abwassers über die Abwassererdleitung eine horizontale oder sogar in Förderrichtung ansteigende Verlegung der Abwassererdleitung und kann somit die zwingende Verlegung der Abwassererdleitung in einem Gefälle vermeiden, wie dies bei schwerkraftbetätigter Abfuhr des Wassers notwendig wäre. Dies ist insbesondere für die Anordnung von mehreren Versorgungsvorrichtungen in beabstandeter Weise vorteilhaft, da diese insgesamt an eine gemeinsame Abwassererdleitung angeschlossen werden können und die Abfuhr des Abwassers ohne Bereitstellung von Hebevorrichtungen oder dergleichen durchgeführt werden könneIt is even more preferred if the waste water pipe and the connection to the underground water pipe are designed for sucking off the waste water by means of a negative pressure. According to this embodiment, the waste water pipes and the ground water pipe as well as the corresponding connection between the waste water pipe and the ground water pipe are designed to be vacuum-resistant, so that the waste water can be suctioned off from the sanitary unit of the vehicle by means of a vacuum. Such a suction, which takes place via the sewage pipe and the sewage underground pipe, is advantageous for various reasons. On the one hand, the variable usability of the supply device is increased in that, in addition to removing the waste water through a lower opening of the waste water tank, it is also possible to remove the waste water through an upper opening of the waste water tank. Furthermore, the vacuum-loaded suction dewaters the sewage pipe and thus reduces the risk of frost immanently, thereby ensuring operational safety at cold outside temperatures. In principle, it is advantageous to lay the underground sewage pipe with a gradient in the direction of discharge of the sewage, even if the sewage is discharged with negative pressure. In principle, the negative pressure discharge of the waste water via the underground sewage pipe allows the underground sewage pipe to be laid horizontally or even uphill in the conveying direction and can thus avoid the mandatory laying of the underground sewage pipe in a gradient, as would be necessary with gravity-driven drainage of the water. This is particularly advantageous for arranging a plurality of supply devices at a distance from one another, since these can all be connected to a common underground sewage pipe and the sewage can be removed without the provision of lifting devices or the like

Noch weiter ist es bevorzugt, wenn die Ventilvorrichtung ausgebildet ist, um einen Übertritt von Flüssigkeit aus dem dritten Ventilanschluss in den zweiten Ventilanschluss in der Zuflussventilstellung, in der Entwässerungsventilstellung und in jeder Ventilstellung zwischen der Zuflussventilstellung und der Entwässerungsventilstellung zu verhindern. Gemäß dieser Ausführungsform ist die Ventilvorrichtung ausgebildet, um eine Verkeimung der Frischwassererdleitung zuverlässig zu verhindern, indem ein Übertritt von Flüssigkeit aus dem dritten Ventilanschluss, also dem zu der Abwasserseite weisenden Ventilanschluss in den zweiten Ventilanschluss, also den mit der Frischwassererdleitung in Verbindung stehenden Ventilanschluss, unterbunden wird. Dies kann zum Beispiel durch eine in der Ventilvorrichtung realisierte bauliche Trennung erfolgen, indem der Auslass des Ventils frei ausgeführt wird, z.B. in einem Auffangtrichter o.ä. der dann an die Abwasserleitung angeschlossen ist. Noch weiter ist es bevorzugt, wenn die Abwasserleitung eine Abwasserrohrleitung und einen Absaugschlauch umfasst und sich von dem unteren Ende zu endseitigen Öffnung des Absaugschlauchs erstreckt und an der endseitigen Öffnung eine Anschlusskupplung für einen gegenüber der Umgebung fluiddichten Anschluss an einen Absauganschluss an dem Fahrzeug angeordnet ist. Gemäß dieser Ausführungsform ist das Ende der Abwasserleitung, mit einer Anschlusskupplung dem Fahrzeug angeordnet ist. Gemäß dieser Ausführungsform ist das Ende der Abwasserleitung, mit einer Anschlusskupplung verbunden, die mit dem Fahrzeug verbunden wird und einen fluiddichten Anschluss an einen Anschluss am Fahrzeug ermöglicht. Diese Anschlusskupplung kann beispielsweise als Bajonettkupplung, Schraubflanschverbindung, Steckverbindung oder dergleichen ausgeführt sein. Die Anschlusskupplung kann über einen Absaugschlauch mit der Abwasserleitung verbunden sein. Hierdurch wird eine flexibel verlegbare Leitung zur Absaugung des Abwassers aus dem Sanitärbereich des Fahrzeugs ermöglicht, was eine hygienische Durchführung des Abwasserabsaugvorgangs erreicht.It is even further preferred if the valve device is designed to prevent liquid from transferring from the third valve port into the second valve port in the inflow valve position, in the drain valve position and in any valve position between the inflow valve position and the drain valve position. According to this embodiment, the valve device is designed to reliably prevent microbial contamination of the fresh water underground pipe by allowing liquid to pass out of the third valve connection, ie the valve connection pointing to the waste water side, into the second valve connection, ie the valve connection connected to the fresh water ground line, is prevented. This can be done, for example, by a structural separation realized in the valve device, in that the outlet of the valve is designed freely, for example in a collecting funnel or the like, which is then connected to the waste water pipe. It is even more preferred if the waste water line comprises a waste water pipeline and a suction hose and extends from the lower end to the end opening of the suction hose and a connection coupling for a fluid-tight connection with respect to the environment to a suction connection on the vehicle is arranged at the end opening. According to this embodiment, the end of the sewage line is arranged with a connection coupling to the vehicle. According to this embodiment, the end of the waste water line is connected to a connection coupling, which is connected to the vehicle and enables a fluid-tight connection to a connection on the vehicle. This connection coupling can be designed, for example, as a bayonet coupling, screw flange connection, plug connection or the like. The connection coupling can be connected to the waste water pipe via a suction hose. This enables a flexibly layable line for sucking off the waste water from the sanitary area of the vehicle, which achieves a hygienic implementation of the waste water suction process.

Noch weiter ist es bevorzugt, wenn die Abwasserleitung eine Abwasserrohrleitung und einen Absaugschlauch umfasst und sich von dem unteren Ende der Abwasserleitung über ein oberes Ende der Abwasserrohrleitung bis zu einer endseitigen Öffnung des Absaugschlauchs erstreckt und ein Absperrventil aufweist zum wahlweisen Sperren oder Freigeben der Abwasserleitung. Gemäß dieser Ausführungsform ist beispielsweise an dem oberen Ende der Abwasserleitung oder im Bereich der endseitigen Öffnung des Absaugschlauchs ein Absperrventil vorhanden, das insbesondere vorteilhaft ist, um bei einer Abwasserabsaugung einen unerwünschten Verlust von Unterdruck in der Abwasserleitung zu verhindern. Das Absperrventil kann grundsätzlich geschlossen sein und erst nach Anschluss der Abwasserleitung an ein Fahrzeug geöffnet werden, um den Absaugvorgang dann durchzuführen und nach erfolgtem Absaugvorgang wieder geschlossen werden.It is even more preferred if the waste water line comprises a waste water pipe and a suction hose and extends from the lower end of the waste water pipe via an upper end of the waste water pipe to an end opening of the suction hose and has a shut-off valve for selectively blocking or releasing the waste water line. According to this embodiment, a shut-off valve is provided, for example, at the upper end of the sewage line or in the area of the end opening of the suction hose, which is particularly advantageous for preventing an undesirable loss of negative pressure in the sewage line during sewage suction. In principle, the shut-off valve can be closed and only opened after the sewage line has been connected to a vehicle in order to then carry out the suction process and be closed again after the suction process has taken place.

Erfindungsgemäß umfasst die Abwasserleitung eine Abwasserrohrleitung, die sich von dem unteren Ende zu einem oberen Ende erstreckt, und wobei zwischen dem oberen Ende und dem unteren Ende ein Anschluss angeordnet ist, der ausgebildet ist, um eine endseitige Öffnung eines an das obere Ende der Abwasserrohrleitung angeschlossenen Abwasserschlauches aufzunehmen und der mittels eines Anschlussabsperrventils zum wahlweisen Sperren oder Freigeben einer Verbindung zwischen dem Anschluss und der Abwasserrohrleitung mit der Abwasserleitung verbunden ist. Gemäß dieser Fortbildung kann ein Abwasserschlauch, der an das obere Ende der Abwasserleitung angeschlossen ist, in einer Ruheposition so an einem Anschluss der Abwasserleitung platziert werden, dass aus dem Abwasserschlauch rücklaufendes Abwasser über diesen Anschluss der Abwasserleitung zugeführt wird und dadurch eine Verschmutzung der Umgebung vermieden wird. Der Anschluss ist mittels eines Anschlussabsperrventils absperrbar, um eine unerwünschte Absaugwirkung am Anschluss, beispielsweise während eines Absaugvorgang, bei dem der Absaugschlauch an einen Abwassertank und nicht an den Anschluss angeschlossen ist, zu verhindern. Das Anschlussabsperrventil kann ein manuell oder durch einen Aktuator gesteuert betätigbares Ventil sein, es kann aber auch ein automatisch durch den Unterdruck in der Abwasserleitung schließendes Ventil sein, dass durch das in den Anschluss eingesteckte beziehungsweise an den Anschluss angeschlossene Ende des Absaugschlauchs geöffnet wird. Der Anschluss kann zur abgedichteten Aufnahme der endseitigen Öffnung des Abwasserschlauchs ausgebildet sein. Dies kann beispielsweise durch eine entsprechende Anschlusskupplung am Anschluss ausgeführt sein, die mit einer dazu passenden Anschlusskupplung an der endseitigen Öffnung des Absaugschlauchs zusammenpasst, beispielsweise eine Camlock-Kupplungsverbindung.According to the invention, the sewage pipe comprises a sewage pipe which extends from the lower end to an upper end, and between the upper end and the lower end there is arranged a connector which is formed to form an end opening of a pipe connected to the upper end of the sewage pipe Waste water hose and which is connected to the waste water pipe by means of a connection shut-off valve for selectively blocking or releasing a connection between the connection and the waste water pipe. According to this training, a sewer hose connected to the upper end of the sewer line is to be placed in a rest position at a connection of the sewage pipe in such a way that waste water running back from the sewage hose is fed to the sewage pipe via this connection, thereby avoiding contamination of the environment. The connection can be shut off by means of a connection shut-off valve in order to prevent an undesired suction effect at the connection, for example during a suction process in which the suction hose is connected to a waste water tank and not to the connection. The connection shut-off valve can be a valve that can be actuated manually or controlled by an actuator, but it can also be a valve that closes automatically due to the negative pressure in the sewage line and that is opened by the end of the suction hose that is inserted into the connection or is connected to the connection. The connection can be designed to receive the end opening of the waste water hose in a sealed manner. This can be implemented, for example, by means of a corresponding connection coupling on the connection, which fits together with a matching connection coupling on the end opening of the suction hose, for example a camlock coupling connection.

Gemäß einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass die Abwasserleitung sich von dem unteren Ende zu einer endseitigen Öffnung zum Anschluss an einen Abwassertank erstreckt und zumindest teilweise als Abwasserschlauchleitung ausgeführt ist, und/oder die Frischwasserleitung sich von dem unteren Ende zu endseitigen Öffnung zum Anschluss an einen Frischwassertank erstreckt und zumindest teilweise als Frischwasserschlauchleitung ausgeführt ist. Gemäß dieser Ausführungsform ist die Abwasserleitung und die Frischwasserleitung oder eine der beiden teilweise als Schlauchleitungen ausgeführt, was die zuvor beschriebenen Vorteile beim Anschluss an ein Fahrzeug ergibt.According to a further preferred embodiment, it is provided that the waste water line extends from the lower end to an end opening for connection to a waste water tank and is at least partially designed as a waste water hose line, and/or the fresh water line extends from the lower end to an end opening for connection extends a fresh water tank and is at least partially designed as a fresh water hose line. According to this embodiment, the waste water line and the fresh water line or one of the two is partially designed as a hose line, which results in the advantages described above when connecting to a vehicle.

Noch weiter ist es bevorzugt, wenn die Ventilvorrichtung manuell von oberhalb der Terrainoberfläche bedienbar ist und frei von elektrischer, pneumatischer und hydraulischer Energiezufuhr ist. Gemäß dieser Ausführungsform ist die Ventilvorrichtung durch eine rein manuelle Betätigung umschaltbar und verzichtet folglich auf eine Energiezufuhr wie beispielsweise eine Zufuhr von elektrischer, pneumatischer oder hydraulischer Energie. Dies ermöglicht es, die Versorgungsvorrichtung unabhängig von einer solchen Energiezufuhr zu installieren und zu betreiben, was für viele Aufstellungsbedingungen vorteilhaft und kostengünstig ist.It is even further preferred if the valve device can be operated manually from above the terrain surface and is free of electrical, pneumatic and hydraulic power supply. According to this embodiment, the valve device can be switched over by purely manual actuation and consequently does not require an energy supply such as, for example, a supply of electrical, pneumatic or hydraulic energy. This makes it possible to install and operate the supply device independently of such an energy supply, which is advantageous and cost-effective for many installation conditions.

Schließlich ist eine Versorgungsvorrichtung nach einer weiter fortgebildeten Ausführungsform gekennzeichnet durch eine in dem Fundamentschacht verlaufende Spülwasserleitung, die im Bereich des unteren Schachtendes einen Spülwasseranschluss aufweist, wobei der Spülwasseranschluss über eine am unteren Ende des Fundamentschachtes angeordnete Spülwasserventilvorrichtung bereitgestellt ist, die über einen ersten Ventilanschluss mit der Spülwasserleitung, über einen zweiten Ventilanschluss mit dem Spülwasseranschluss und über einen dritten Ventilanschluss mit einem Spülwasserablaufanschluss in Verbindung steht und in einer Spülwasserzuflussventilstellung den ersten und zweiten Ventilanschluss miteinander verbindet und den dritten Ventilanschluss sperrt, in einer Spülwasserentwässerungsventilstellung den ersten und dritten Ventilanschluss miteinander verbindet und den zweiten Ventilanschluss sperrt. Gemäß dieser Ausführungsform ist eine Spülwasserleitung vorhanden, die dazu dient, eine Spülung des Abwassertanks des Fahrzeugs nach dessen Entleerung vorzunehmen. Die Spülwasserleitung ist zusätzlich zur Frischwasserleitung vorgesehen, beispielsweise um zu vermeiden, dass die Frischwasserleitung für einen solchen Spülvorgang benutzt werden muss oder kann, was aus hygienischen Gründen oder zur Einsparung von Frischwasser vorteilhaft sein kann. Die Spülwasserleitung ist in gleicher Weise wie die Frischwasserleitung für eine Entwässerung ausgerüstet. Diesbezüglich wird Bezug auf die voranstehenden Erläuterungen für die funktionellen und konstruktiven Eigenschaften der Frischwasserleitung in Bezug auf deren Entwässerung genommen. Insbesondere kann die Entwässerung der Spülwasserleitung in gleicher Weise fortgebildet werden wie die zuvor beschriebene Entwässerung der Frischwasserleitung.Finally, a supply device according to a further developed embodiment is characterized by a flushing water line running in the foundation shaft, which has a flushing water connection in the area of the lower shaft end, the flushing water connection being provided via a flushing water valve device arranged at the lower end of the foundation shaft, which is connected via a first valve connection to the flushing water line, via a second valve connection to the flushing water connection and via a third valve connection to a flushing water outlet connection in is connected and in a rinsing water inflow valve position connects the first and second valve port and blocks the third valve port, in a rinsing water drainage valve position connects the first and third valve port and blocks the second valve port. According to this embodiment, there is a flushing water line which is used to flush the waste water tank of the vehicle after it has been emptied. The rinsing water line is provided in addition to the fresh water line, for example to avoid the fresh water line having to or being able to be used for such a rinsing process, which can be advantageous for hygienic reasons or for saving fresh water. The rinsing water line is equipped for drainage in the same way as the fresh water line. In this regard, reference is made to the above explanations for the functional and structural properties of the fresh water line with regard to its drainage. In particular, the drainage of the flushing water line can be developed in the same way as the drainage of the fresh water line described above.

Eine bevorzugte Ausführungsform der Erfindung wird anhand der beiliegenden Figur erläutert. Die Figur zeigt eine schematische Darstellung einer erfindungsgemäßen Versorgungsvorrichtung.A preferred embodiment of the invention is explained with reference to the attached figure. The figure shows a schematic representation of a supply device according to the invention.

Die Figur zeigt eine Ausführungsform der erfindungsgemäßen Versorgungsvorrichtung mit einem Trinkwasserschlauch 10 und einem Absaugschlauch 20, die jeweils Bestandteil einer Trinkwasserleitung und einer Abwasserleitung sind.The figure shows an embodiment of the supply device according to the invention with a drinking water hose 10 and a suction hose 20, which are each part of a drinking water line and a waste water line.

Der Trinkwasserschlauch 10 ist auf Höhe der Terrainoberfläche 100 mit einer Trinkwasserrohrleitung 11 verbunden, die ebenfalls Bestandteil der Trinkwasserleitung ist. Der Absaugschlauch 20 ist in gleicher Weise auf Höhe der Terrainoberfläche 100 mit einer Abwasserrohrleitung 21 verbunden, die Bestandteil der Abwasserleitung ist. Das Ende 12 des Trinkwasserschlauchs weist eine Trinkwasserkupplung auf, die zum Anschluss an eine entsprechende Kupplung am Fahrzeug ausgebildet ist. Der Trinkwasserschlauch ist mittels einer an einer Seilzugvorrichtung 15 befestigten Umlenkrolle 16 an einem in Form eines T ausgebildeten Haltemast 30 aufgehängt. Die Figur zeigt die Position in einer Ruhelage. Aus dieser Ruhelage kann der Trinkwasserschlauch 10 durch Ausziehen des Seilzugmechanismus 15 herausbewegt werden, um den Anschluss an ein Fahrzeug herzustellen.The drinking water hose 10 is connected at the level of the terrain surface 100 to a drinking water pipeline 11, which is also part of the drinking water line. The suction hose 20 is connected in the same way at the level of the terrain surface 100 to a waste water pipe 21 which is part of the waste water pipe. The end 12 of the drinking water hose has a drinking water coupling that is designed for connection to a corresponding coupling on the vehicle. The drinking water hose is suspended by means of a deflection roller 16 attached to a cable device 15 on a holding mast 30 designed in the shape of a T. The figure shows the position in a rest position. Out of From this rest position, the drinking water hose 10 can be moved out by pulling out the cable pull mechanism 15 in order to connect it to a vehicle.

Die Trinkwasserrohrleitung 11 und die Abwasserrohrleitung 21 verlaufen unterirdisch in einem Fundamentschacht 40. Der Fundamentschacht 40 erstreckt sich ausgehend von einer Fundamentschachtplatte 41 nach unten bis auf eine Tiefe, die so tief im Erdreich liegt, dass dort Frostsicherheit zu jeder Jahreszeit besteht.The drinking water pipeline 11 and the waste water pipeline 21 run underground in a foundation shaft 40. The foundation shaft 40 extends from a foundation shaft plate 41 down to a depth that is so deep in the ground that there is frost protection at any time of the year.

Am unteren Ende der Trinkwasserrohrleitung 11 ist diese mittels eines 3/2-Wegeventils 50 mit einer Trinkwassererdleitung 60 einerseits und einer Rücklaufleitung 70 andererseits verbunden. Das 3/2-Wegeventil 50 ermöglicht eine Ventilstellung, in der Trinkwasser aus der Trinkwassererdleitung 60 in die Trinkwasserrohrleitung 11 hindurchtritt und die Rücklaufleitung gesperrt ist und eine zweite Stellung, in der Trinkwasser aus der Trinkwasserrohrleitung 11 in die Rücklaufleitung 70 strömen kann und die Trinkwassererdleitung abgesperrt ist. Hierdurch wird einerseits die Zufuhr vom Trinkwasser in den Trinkwasserschlauch 10 aus der Trinkwassererdleitung ermöglicht und andererseits die Entwässerung des Trinkwasserschlauchs 10 nach Gebrauch in die Rücklaufleitung 70 ermöglicht. Dabei ist das 3/2-Wegeventil 50 rücklaufseitig mit einem Systemtrenner 51 verbunden, der solcher Art konstruiert ist, dass ein Übertritt von Keimen aus der Rücklaufleitung 70 in die Trinkwassererdleitung 60 oder die Trinkwasserrohrleitung 11 über das 3/2-Wegeventil nicht möglich ist.At the lower end of the drinking water pipeline 11, this is connected by means of a 3/2-way valve 50 to a drinking water underground pipe 60 on the one hand and a return pipe 70 on the other. The 3/2-way valve 50 enables a valve position in which drinking water can flow from the drinking water underground pipe 60 into the drinking water pipe 11 and the return pipe is blocked, and a second position in which drinking water can flow from the drinking water pipe 11 into the return pipe 70 and the drinking water underground pipe is blocked is. As a result, on the one hand, the supply of drinking water into the drinking water hose 10 from the drinking water underground line is made possible and, on the other hand, the drainage of the drinking water hose 10 into the return line 70 after use is made possible. The 3/2-way valve 50 is connected to a system separator 51 on the return side, which is constructed in such a way that germs cannot pass from the return line 70 into the drinking water underground line 60 or the drinking water pipeline 11 via the 3/2-way valve.

Der Absaugschlauch 20 ist durch eine Umlenkrolle 26 am oberen Ende des Haltemastes 30 umgelenkt, sodass die endseitige Öffnung des Absaugschlauchs in Richtung des Fundamentschachts 40 zurück umgelenkt ist. Die Umlenkrolle 26 ist beweglich an dem Haltemast befestigt und in eine obenliegende Position, wie abgebildet in den Figuren, vorgespannt. Diese Vorspannung kann beispielsweise durch ein mittels einer Seilzugvorrichtung 25 mit der Umlenkrolle verbundenes Gewicht oder durch ein elastisches Element wie eine mechanische Feder bewirkt werden. Der Absaugschlauch 20 kann aus der Ruheposition durch Ausziehen des Seilzugmechanismus 25 herausbewegt werden, um ihn mit einer entsprechenden Kupplung an einem Absaugstutzen eines Abwassertanks am Fahrzeug zu verbinden.The suction hose 20 is deflected by a deflection roller 26 at the upper end of the holding mast 30 so that the opening at the end of the suction hose is deflected back in the direction of the foundation shaft 40 . The idler pulley 26 is movably attached to the support pole and is biased to an overhead position as shown in the figures. This pretension can be brought about, for example, by a weight connected to the deflection roller by means of a cable pull device 25 or by an elastic element such as a mechanical spring. The suction hose 20 can be moved out of the rest position by pulling out the cable pull mechanism 25 in order to connect it to a corresponding coupling on a suction socket of a waste water tank on the vehicle.

Der Absaugschlauch 20 weist an seiner endseitigen Öffnung 22 eine Anschlusskupplung 80 mit Anschlusskupplungsabsperrventil 81 auf, die zur abgedichteten Verbindung mit dem Absaugstutzen des Abwassertanks an dem Schienenfahrzeug ausgebildet ist. Die Anschlusskupplung 80 kann beispielsweise eine Camlock-Kupplung sein. Im Bereich der Verbindung des Absaugschlauchs 20 mit der Absaugrohrleitung 21 ist ein Anschluss 85 mit einem Anschlussabsperrventil 86 vorgesehen. An diesen Anschluss 85 kann die Anschlusskupplung 80 in einer Ruheposition angeschlossen werden und dadurch aus dem Absaugschlauch rücklaufendes Abwasser zuverlässig in die Abwasserleitung aufgenommen werden. Durch das Anschlussabsperrventil 86 kann ein unerwünschter Unterdruckverlust zuverlässig verhindert werden, wenn die Anschlusskupplung 80 nicht an den Anschluss 85 angeschlossen ist.At its end opening 22, the suction hose 20 has a connection coupling 80 with a connection coupling shut-off valve 81, which is designed for a sealed connection to the suction socket of the waste water tank on the rail vehicle. The connection coupling 80 can be a camlock coupling, for example. A connection 85 with a connection shut-off valve 86 is provided in the area where the suction hose 20 is connected to the suction pipeline 21 . The connection coupling 80 can be connected to this connection 85 in a rest position, and as a result, waste water flowing back from the suction hose can be reliably taken up into the waste water line. The connection shut-off valve 86 can reliably prevent an undesired loss of vacuum when the connection coupling 80 is not connected to the connection 85 .

Die Abwassererdleitung 21 ist an eine unterirdisch verlegte Vakuumleitung 90 angeschlossen, in der ein Unterdruck anliegt, der durch Öffnen des Ventils 81 auf die Absaugschlauchöffnung am Ende des Absaugschlauchs einwirkt. Hierdurch wird eine Absaugung von Abwasser über die Absaugkupplung 80 des Absaugschlauchs in die Vakuumleitung 90 ermöglicht.The sewage underground line 21 is connected to an underground vacuum line 90 in which a negative pressure is present, which acts on the suction hose opening at the end of the suction hose by opening the valve 81 . This enables waste water to be suctioned off via the suction coupling 80 of the suction hose into the vacuum line 90 .
