Description

The invention relates to a rail vehicle with a fresh water connection and a sewerage system connection, the hinged lid being located in front of the fresh water connection so that it locks it in the closed position and unlocks it in the open position.

In passenger rail vehicles that bring fresh water for people to use, such as boiling, washing, showering, etc., must carry hygiene regulations to ensure water quality. For this, along with the requirements for the storage and dispensing of fresh water, water bypass is also regulated from stationary drinking water installations to mobile devices for storage and dispensing. This includes, along with the technical minimum requirements for the mobile unit and its condition, among other things, also instructions for filling fresh water tanks.

The purpose of the requirements for action is to prevent contamination and contamination of fresh water and fresh water installations both on the vehicle and on-board. In particular, contaminants that could have occurred when connecting the suction device to the sewer system of the train, as well as during the suction process itself, should be excluded. This, for example, splashes and droplets from the sewage zone of connections to it.

To protect the quality of fresh water in trains, for example, methods are clearly shown in figures 1 to 5.

FIG. 1 shows an example of the arrangement of a device for filling a fresh water tank and a device for emptying a wastewater tank of a rail vehicle. The vehicle connection 2 to the sewage system and the vehicle connection 1 for fresh water located on the vehicle are located on the same side of the rail vehicle, however, at a great distance from each other. Due to the spatial separation, the possibility of contamination of the connection 1 for fresh water with droplets or splashes from the sewer area and the connections to it is reduced.

The arrangement of FIG. 2 vehicle connection 2 to the sewerage system and vehicle connection 1 for fresh water on different surfaces or sides of the rail vehicle serves the same purpose of preventing the contamination caused by the mutual connection.

FIG. 3 to 5 show the connection 1 of fresh water and connection 2 to the sewage system with hinged lids 4a and 4b and the interaction when closing. Access to connections 1 and 2 is controlled by hinged covers 4a and 4b, and only one hinged cover 4a or 4b can always be opened. Accordingly, the other hinged lid is then closed. FIG. 3 shows the open hinged lid 4b, before connecting 2 to the sewage system, which in this position releases connection 2 to the sewage system. On the contrary, the hinged cover 4a is closed before the fresh water connection, and thus completely blocks the connection for fresh water. If the hinged lid 4a nevertheless opens, as is clearly shown in FIG. 4, the hinged lid 4b closes automatically. The hinged lids 4a and 4b are mutually connected. In FIG. 5, the hinged lid 4a is now open and unlocks before connecting 1 for fresh water, and the hinged lid 4b is closed and blocks the connection to the sewage system.

Common to all these devices is that during the suction process and the corresponding actions, infection of the fresh water area is prevented.

The utility model is based on the task of proposing a device for a simple and reliable supply of fresh water for a rail vehicle.

The problem is solved using the subject of independent paragraph 1 of the utility model formula. Improved variants and variants of the utility model are contained in the features of the dependent claims of the utility model.

The rail vehicle proposed in accordance with the utility model includes a connection for fresh water, a connection to a sewage system and a hinged lid that is located in front of the connection for fresh water so that it locks it in the closed position and unlocks it in the open position.

In addition, the rail vehicle proposed in accordance with the utility model includes a recognition unit for detecting the position of the hinged lid and an actuator. The actuator is connected to the recognition unit in such a way and is located on the connection to the sewage system so that the actuator blocks the full connection of the station connecting fitting to the connection to the sewer system or the opening of the shut-off element for connecting to the sewage system to lock or regulate the flow through the connection to the sewage system, if the hinged lid is in the open position.

In particular, the actuator in the first position makes it possible to fully connect the station connecting fitting or open the shutoff member to connect to the sewage system if the hinged lid is in its closed position. The position of the actuator depends on the position of the hinged cover. The recognition unit is used to register the position of the hinged lid and thus, at least indirectly, in relation to the position of the actuator. For this, the recognition unit and the actuator are appropriately connected to each other.

The connection of the actuator with the recognition unit is carried out, for example, mechanically, electrically, pneumatically or hydraulically. In this case, the actuator is connected to the recognition unit mechanically, electrically, pneumatically or hydraulically. The connection between the recognition unit and the actuator serves to transmit a signal, - effort and / or energy, and is formed accordingly.

According to a first improved embodiment of the utility model, the actuator and the recognition unit are connected using a Bowden cable. Alternatively, the actuator and the recognition unit can be connected to each other via a hydraulic connection. It is further possible that the actuator connection includes an electric actuator as an actuator, and the recognition unit has a sensor that converts the registered position of the hinged lid into an electrical signal suitable for further processing, and the actuator and recognition unit are connected to each other by an electrical connection. Another improved variant of the utility model thus provides for an electrical connection between the actuator and the recognition unit. Thus, by means of an electrical connection, an actuator is controlled.

The actuator itself is located in the area of the fitting of the sewage system, in particular, directly on the fitting of the sewage system, and includes, for example, a bolt or an annular plate. The bolt or ring plate in the second position of the actuator is so offset in the direction of connection to the sewage system that they act as a stop for the station connecting fitting to block the complete connection of the station connecting fitting. In the first position of the actuating device, they are opposite offset away from the fitting of the sewer system, so that they no longer act as a stop for the station connecting fitting and release the connection to the sewer system to fully connect the connecting fitting. The bolt or annular plate can also be displaced in the second position of the actuator so that they act as a stop for a particularly manually actuated, switching lever of the locking member to open and close the locking member in order to block the opening of the locking member.

In its first position, the actuator allows full connection of the connecting fitting of the station pipeline of the sewage system to the connection to the sewage system of the rail vehicle. In the second position, on the contrary, it blocks the full connection of the station connecting fitting to the connection to the sewage system. The connection of the actuator with the recognition unit ensures that the actuator is in the first position if the recognition unit registers that the hinged lid is in the closed position. On the contrary, the connection ensures that the actuator is in the second position if the recognition unit registers that the hinged lid is in the open position.

In an improved embodiment, the actuator with the recognition unit is connected so that, in particular, the movement of the hinged lid from the closed position to the open position leads to the movement of the actuator from the first position to the second position. Likewise, it translates, in particular, the movement of the hinged cover from open to closed position to the movement of the actuator from the second position to the first position.

Similarly to actuating the actuator with a hinged lid, the actuator could be connected by the recognition unit as an alternative or additionally, thus the connection could be formed appropriately in such a way that the translation, in particular the movement, of the actuator from the first position to the second position would lead to the transfer, in particular to the movement, of the hinged lid from the closed to the open position, and / or that the translation, in particular, the movement, use The filling device from the second position to the first position would lead, in particular, to the movement of the hinged lid from the open position to the closed position. In the latter case, in this way the hinged lid closes when the station connecting fitting is planted.

Likewise, the hinged lid may close when the locking element is opened.

By the complete connection of the station connecting nipple to the connection to the sewage system, we mean the landing of the connecting nipple for connection to the sewage system up to the final position, fixing and thus the associated seal of the connecting nozzle with respect to the connection to the sewage system. In this case, the station connecting fitting, in particular, is formed complementary to the connection to the sewage system. The connection to the sewage system and the connecting nipple form complementary nipple connections with each other.

Typically, a connection to a sewage system has, in particular, a shut-off element, for example a ball valve, to be manually actuated. The actuating device can thus be located in the area of connection to the sewage system and, depending on the position of the hinged lid registered by the recognition unit, is set so that it prevents the opening of the locking member of the connection to the sewage system if the hinged lid is not completely closed. In particular, the manual opening of the locking element is mechanically blocked by an actuator, as already described above, for example, with a bolt.

In the case of a rail vehicle, it is, for example, a locomotive or a rail vehicle for passenger communication.

The fresh water connection, sometimes also called the filling nozzle, is used to connect the station fresh water pipeline to fill the fresh water tank of the rail vehicle with fresh water. The connection to the sewage system therefore serves to connect the station sewer pipe to empty the drain tank of the rail vehicle.

The hinged cover before connecting to fresh water in its closed position protects it from environmental influences, in particular, from splashes or droplets when draining the wastewater of a rail vehicle from being connected to the sewage system. In its open position, it unlocks it to connect the fresh water pipeline.

Therefore, the connection to the sewage system can be located in the immediate vicinity of the connection for fresh water, in particular also on the same side of the rail vehicle. The risk of contamination of fresh water with splashes or droplets of wastewater is minimized using the utility model.

The connection to the sewage system is preferably located externally on the vehicle, in particular with free access. It is not covered by a lid. Even in the second position of the actuating element, the connection to the sewage system is freely accessible and not covered by a lid. The actuating element prevents only the complete connection of the station connecting fitting to the connection to the sewer system or the opening of the shut-off member for connecting to the sewer system. Also, the fresh water connection is preferably located externally on the vehicle. Both the connection to the sewage system and the connection for fresh water are made appropriately in order to be able to connect respectively normalized filling devices and / or suction devices. Their geometry corresponds, for example, to the requirements of TSI RST HS (Technical Specifications for the Interoperability of Rolling Stock Subsystems), chapter 4. 2. 9. 3.

The rail vehicle proposed in accordance with the utility model is operable using the following method steps:

- closing the hinged lid before connecting for fresh water;

- full connection of the station connecting fitting to the connection to the sewage system or the opening of the shut-off member connecting to the sewage system;

- emptying the tank with wastewater of a rail vehicle.

Emptying is carried out, in particular, by pumping wastewater. This is possible if the hinged lid is fully closed.

Alternatively, the open lid is closed by fully connecting the station connecting fitting to the connection to the sewer system or by opening the shut-off member of the connection to the sewer system due to the proposed connection between the actuator and the recognition unit.

On the contrary, to fill the tank for fresh water of the rail vehicle, the following steps of the method are performed:

- the complete disconnection of the station connecting fitting from the connection to the sewage system or the closure of the shut-off member of the connection to the sewage system;

- opening the hinged lid before connecting for fresh water;

- full connection of the station connecting fitting to the connection for fresh water;

- filling the tank for fresh water of the rail vehicle.

Filling is carried out, in particular, by pumping fresh water.

The utility model describes the design and location of the connection for fresh water and the connection to a sewage system for connecting to a fresh water station pipe or a sewage pipe on a rail vehicle in order to maintain the requirements regarding the operation by means of technical devices, and thus the purpose of the requirements in terms of actions, namely, to prevent the pollution and contamination of fresh water and the installation for fresh water both from the side of the train and from the station. This is realized by restricting access only in the connection area for fresh water using a hinged roof. Connection to the sewage system does not require any other cover. For this purpose, for example, a mechanism is installed that blocks the nozzle and seal of the station sewer device.

This is done, for example, by means of a stop depending on the position of the hinged lid before connecting to fresh water. This contributes to the fact that the normalized connecting fitting of the station sewer device cannot be pushed and fixed in the sealing position. Wastewater is discharged from a rail vehicle in the traditional way through connection to a sewage system using suction from a wastewater tank.

Additionally, when the connecting nipple is fully connected to the sewage system or when the shut-off element is opened, the hinged lid can be closed and held in the closed position before connecting to fresh water.

The utility model allows numerous forms of implementation. It is explained in more detail using the following figures, which respectively represent an example implementation. Identical elements in the figures are provided with the same reference position. The drawings show the following:

FIG. 12 - mechanical connection of the hinged cover recognition unit and the actuator.

In FIG. 6 shows a rail vehicle proposed in accordance with a utility model in an embodiment with a connection 1 for fresh water and a connection 2 to a sewage system.

Connection 1 for fresh water and connection 2 to the sewage system are located on the same side of the rail vehicle in close proximity to each other. This gives advantages in the arrangement of pipelines in a vehicle, as well as when filling with fresh water and pumping wastewater.

The hinged lid 4 is thus located in front of the fresh water connection 1 so that when the hinged lid 4 is closed, it is blocked by the hinged lid 4, and in the open position of the hinged lid 4 it is free.

In FIG. 7 hinged cover is presented in detail. A recognition unit 5 is provided for registering the position of the hinged lid 4, i.e. whether the hinged lid is open or closed.

Near the hinged lid, the connection 2 to the sewage system is schematically shown. Actuator 3 is located on it. Actuator 3, here with a Bowden cable 7, is connected to the recognition unit 5 so that the actuator 3 in the first position makes it possible to fully connect the station connecting fitting 8 to connection 2 to the sewage system only when hinged lid 4 is fully closed.

Similarly, the actuator 3 in the second position with at least partially open or at least not fully closed hinged lid, ensures that the full connection is blocked. The actuator 3 is installed respectively using the recognition device 5.

The recognition unit 5 installs an actuator 3. However, the opposite is also possible. When the connecting fitting 8 is fully seated at connection 2 to the sewage system, the hinged cover 4 closes. The recognition unit 5 and the actuator 3 are connected, for example, mechanically. Here, a Bowden cable 7 is provided for connection. The actuator 3 in this embodiment includes a bolt 9, which is fixed and mounted on the connection 2 to the sewage system with the possibility of movement along the longitudinal direction. The force for moving the bolt 9 is created using the hinged cover 4 and is transmitted through the recognition unit 5 and the Bowden cable 7 to the bolt 9.

The clearance around TSI RST HS normalized, chapter 4.2.9.3 or structurally identically connecting the nozzle 8 of the station suction device during use of the filling device by means of the bolt 9 is limited in general, so that the complete planting of the station connecting nozzle 8 to the end position is not possible.

In this case, the opening of the hinged lid 4 is recognized by the recognition unit 5. Based on this, the bolt 9 is moved forward with the Bowden cable 7 to a position that prevents the connecting fitting 8 of the suction pipe from completely connecting the vehicle 2 to the sewage system to the locked position, as well as fixing and sealing the eccentric quick coupler according to TSI RST HS , chapter 4.2.9.3 or structurally identical.

The complete connection of the connecting nozzle 8 to the connection 2 to the sewage system first of all means the mechanical closure between the connecting nozzle 8 and the connection 2 to the sewage system, for example, pushing the connecting nozzle 8 to the sealing position and, in this case, fixation in this position. The connection of the connecting fitting 8 to the connection 2 to the sewage system is most often carried out manually.

FIG. 8 clearly shows another embodiment of actuator 3. Instead of the bolt 9 of FIG. 7 here, an annular plate 10 serves as an abutment for the connecting nozzle 8. The annular plate 10, when the hinged lid is closed, is likewise mounted with the recognition unit in such a way that the full connection of the station connecting nozzle 8 is impossible. On the contrary, the actuator 3 with the annular plate 10 in its first position allows the full connection of the station connecting fitting. In this case, the hinged lid is in the closed position and the fresh water connection is completely blocked.

And here, with the help of Bowden cable 7, due to the landing of the station connecting fitting 8 on the vehicle’s connection to the sewage system and as a result of the actuation of the bolt or ring plate 10, the hinged lid can be folded to the closed position before connecting to fresh water from the open position.

In FIG. 9 and 10, the landing of the connecting nipple 8 to connect 2 to the sewage system is prevented or allowed by means of a pin 11 which is recessed in the connection to the sewage system 2 as a means of the actuator 3. The pin 11 is again installed using the recognition unit. In the image of FIG. 9, the pin 11 in the extended position blocks the fit of the connecting fitting of the pipe 8, in the image of FIG. 10 allows it thanks to the recessed pin 11.

In FIG. 11 shows another embodiment of a utility model. Here, the actuator 3 is here again connected with the Bowden cable 7 to the recognition unit 5 in such a way that the actuator 3 in the first position allows the opening of the locking element 6 of the connection 2 to the sewage system only if the hinged cover 4 is completely closed. Similarly, the actuator 3 in the second position with the at least not fully closed hinged lid ensures that the opening of the locking member 6 is blocked.

The locking member 6 from the closing position (indicated by the solid line) can be set to the opening position (indicated by the dashed line) if the hinged cover 4 from the open position (shown here) has moved to the closed position (shown by arrow). The opening of the hinged lid 4 is detected on the recognition unit 5. Through the connection, here is the Bowden cable 7, the actuator 3, if necessary, moves from the opening position to the closing position.

On the contrary, the action when opening the shut-off member 6 from the closed position to the open position can move the hinged lid 4 from the open position to the closed position and prevent the use of connection 1 for fresh water.

The actuator 3 includes here in a manner similar to the embodiment of FIG. 7, a bolt 9, which serves as a stop for the lever of the locking member 6. The actuator 3 can be located on the body of the vehicle and is firmly connected to it.

FIG. 12 is a schematic sketch of the principle of operation of the Bowden cable as a practical implementation of the connection of the recognition unit 5 and the actuator 3. In this case, the inner rod 12 (tensile force) and the outer rod 13 (compressive force) move relative to each other. A tensile force on the inner link 12 pushes the bolt 9 out of the housing 14 in which it is installed. The housing 14 is located, for example, on the connection 2 to the sewage system or on another fixed point of the vehicle. In this example, the recognition unit 5 consists mainly of attaching the inner link 12 to the hinged lid and the outer link 13 to the casing 14. When opening the hinged cover 4, a tensile force is applied to the inner link, the consequence of which is to pull the bolt 9 back.

In addition to the Bowden cable, other mechanical forces are possible between the recognition unit and the actuator. This mechanical transmission of forces is carried out, for example, by means of a rod, a gear wheel, cable traction or another.

An electrical signal transmission between the recognition unit and the actuator is also possible. When the electrical contact is opened on the controlled node, the actuator is activated. In addition, a hydraulic transmission of forces may be provided between the recognition unit and the actuator.
