Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a water filling device for sanitary facilities in vehicles 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.
  • EP 0 404 170 A1 a device for sucking liquids from a tank located in a vehicle. The liquid is sucked out by vacuum.
  • 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.
  • a supply device which is installed in a stationary manner.
  • the supply device has a foundation shaft that can be designed as a foundation pipe.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the valve device serves to achieve reliable avoidance of frost damage in the fresh water line.
  • the valve device is arranged in the depth of the foundation shaft and can thus be arranged in a frost-proof area.
  • 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.
  • 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.
  • 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.
  • valve device 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • valve device is a 3/2-way valve.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the vacuum-loaded suction dewaters the sewage pipe and thus reduces the risk of frost immanently, thereby ensuring operational safety at cold outside temperatures.
  • 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
  • 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.
  • 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.
  • 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.
  • the end of the sewage line is arranged with a connection coupling to the vehicle.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • valve device can be operated manually from above the terrain surface and is free of electrical, pneumatic and hydraulic power supply.
  • 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.
  • a supply device 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.
  • a flushing water line which is used to flush the waste water tank of the vehicle after it has been emptied.
