Description

The invention relates to a tank container for the delivery of fuel to rail vehicles. The tank container can be used as a temporary filling station at all locations of the rail network, which can be reached with a truck with container semi-trailer. By remote monitoring of the level data as well as the safety components, with which the tightness of the device is supervised, the tank container fulfills the water protection regulations, without that specially trained specialized personnel must be used permanently on site.

Deutsche Bahn AG has a network of tank systems for supplying rail vehicles with diesel fuel. During construction work on the railway network, it sometimes happens that tank systems are temporarily unavailable. For the customers of the unavailable tank plants, this means a disproportionately high effort to drive to the next stationary fueling system. The same applies to the period of renovations or major modifications to the tank facilities themselves. Therefore, the refueling of rail vehicles in such cases must be realized by means of emergency refueling. In the case of emergency refueling, the rail vehicles are refueled by qualified personnel in compliance with the laws and regulations relevant to water protection by means of transportable tank systems or directly from the tanker vehicles. This requires a very high amount of personnel, preparatory work and time and again instructions from the employees involved. In addition, there remains a residual risk in compliance with the protection of water during self-refueling by the customers.

For this reason, it is desirable to reduce the expense of refueling rail vehicles using flexibly deployable, non-stationary refueling devices. In doing so, it must be ensured that the specifications of water protection are complied with even if no specially trained specialist personnel carries out the refueling. From the DE 101 39 353 B4 is a portable, completely prefabricated tank system for the delivery of fuel known. Here, a tank container is used, which consists of a built-in an ISO container fuel tank, which is separated by an all-tightly welded partition from an operating room, the inner wall of the container is formed by a shell that between the outer walls, the bottom wall and Roof wall divides a monitoring space, which is connected to a leakage protection device.

Disadvantages of this tank container are that the tank container area is not accessible because the leakage monitoring space is not sufficiently dimensioned to be able to catch a significant portion of the tank contents in case of a leak in the fuel tank area if necessary. If a leak occurs on the tank, it is necessary to open the interstitial space and thus a high outlay for repair.

From the DE 103 52 306 B4 For example, a container for transporting a combustible fluid is known, which is provided with sidewalls, a floor, a ceiling, a storage room, an operating space separated by a partition wall, a plurality of double-walled fluid tanks and an encapsulated generator for generating the energy for the operating room. Again, there are problems with a leak on a tank. Although the interstitial space is accessible from the outside via side doors, it can not be opened in the event of a leak without fuel escaping into the environment. Thus, a high effort for repair is required here.

Furthermore, in the case of both tank containers, it is not guaranteed that the requirements of water protection legislation will be complied with when refueling rail vehicles in the track area. The operation of these tank containers is therefore only possible where permanently qualified specialist personnel are on site.

It is an object of the invention to provide a mobile tank container that can be produced and maintained on the one hand with little effort, and on the other hand can be used for refueling rail vehicles in the track area. At the same time refueling should be possible without additional specialist personnel, solely by instructed customers.

The object is achieved by means of a device according to claim 1.

Claim 1 describes an easily manufactured tank container that can be transported to any place that is accessible to a truck with container trailer. To ensure that the tank container can also be used in remote areas without the presence of qualified personnel, it must be ensured that no fuel can penetrate the soil in the event of leakage. Therefore, the storage tank is placed in a collection room in the container, which can hold up to 100% of the tank contents. The catchment area is created by the fact that an upwardly open partition tightly seals an area in the container by welding it to the bottom plate and the side walls of the container. Since the partition wall is open at the top, the tank container is accessible in the interstitial space, so that service personnel have access to the tank container without great effort when a leak occurs. To prevent fuel from leaking out of the container even in the event of leaks at the pump, it is also mounted in the catchment area. So that the pump does not come into contact with the escaping fuel during a leak, it stands on a pedestal in the collecting area. Furthermore, a remote monitoring device is installed, with the permanent filling and discharge quantities and the installed safety devices are monitored to monitor the tightness of the system.

Thus, it is always known at a central remote monitoring station whether the tank container is properly available or there is a need for maintenance. A specially trained specialist on site is only required for filling the storage tank or during maintenance.

The claims 2 to 17 describe advantageous embodiments of the main claim.

According to claim 2, the tightness of the storage tank is advantageously monitored by an oil-water warning device, the probe is installed at the bottom of the collecting space. As soon as fuel escapes through a leak in the storage tank or in other components installed in the sump, it collects at the bottom of the sump. There he is detected by the oil-water warning device. If this happens during a refill or refueling, these operations are automatically stopped.

Since it can also come in the operating range to a leakage of fuel, there is advantageously installed according to claim 3 on the floor covered with a grid collecting space. A probe of an oil-water warning device is installed in the catchment room and monitors the operating area.

According to claim 4 double wall hoses are installed both for filling and for refueling, which are equipped with a warning system. A monitoring circuit automatically shuts off the filling or refueling operation when the warning system detects a leak in a double-walled hose. This also ensures that leaks outside the catchment area are reliably detected and contamination of the soil is avoided.

According to claim 5, a level gauge measures the level of the storage tank and displays this on a display in the service room.

According to claim 6, a limit sensor monitors the filling of the storage tank. Once the storage tank is filled to a predetermined volume, this is detected by the limit sensor and forwarded to a tanker associated limit switch circuit, which terminates the filling automatically.

According to claim 7, a tear-off is mounted on the filling hose for the storage tank. It prevents fuel from escaping if the filling hose breaks off at the coupling point to the tanker.

According to claim 8, a ball valve and a check valve are installed on the filling line. The non-return flap prevents backflow of accumulated fuel to the tanker truck coupling. The ball valve allows tight sealing of the filling line for repair purposes or as additional security.

According to claim 9, the dispenser is equipped with a limit switch circuit. It automatically interrupts the refueling process when the tank to be refueled has been sufficiently filled. This prevents overflow of the fuel from the tank to be refueled.

According to claim 10, a so-called deadman switch is installed on the dispensing hose. A deadman circuit monitors whether the deadman switch is pressed. Only when this is the case does the dead man's circuit allow refueling. This prevents refueling of the tank end from the fuel nozzle and unattended fuel is discharged, which could go unnoticed in the environment.

In accordance with claim 11, a tear-off is installed between the nozzle and double-walled dispensing hose. It prevents fuel from leaking when the dispensing valve is torn off from the dispensing hose due to external influences, for example due to a fall or departure of the refueling end.

According to claim 12 of the dispensing hose is equipped either with a self-tapping nozzle or a full hose dry clutch. A self-tapping nozzle closes automatically when the liquid level in the tank to be filled reaches the maximum level. In the case of refueling a vehicle fleet equipped with dry clutches, it is possible to use a dispensing hose instead of a Dispensing valve mounted a dry clutch. This allows absolutely leak-free refueling.

According to claim 13, all messages of the installed safety and monitoring devices converge in a fault message module. The fault message module receives and processes the data. The relevant data is transmitted from the safety devices to so-called reporting lines. When a safety device triggers, the associated signal line triggers. This means that the mobile tank container is automatically disturbed, filling and refueling operations are no longer possible.

According to claim 14, a fuel terminal detects the tank data. This is all current data such as date, time, amount of fuel tapped, product and vehicle at the time of refueling. Furthermore, the fuel terminal ensures that the dispenser is only released for authorized customers. This prevents unauthorized persons from taking fuel. At the same time, all data is collected for the automated billing of the customer.

According to claim 15, the fuel terminal of claim 14 is equipped with a transponder reader. With a transponder, the characteristics of the customer can be transferred to the automatic teller machine in a particularly convenient and advantageous manner.

In accordance with claim 16, a remote data transmission transmits the messages of the fault message module, the operating state and the filling and dispensing quantities determined by the filling level probe to a central monitoring point. This can be done by call or automatically. With the help of this data, the central monitoring station is informed about all relevant operating parameters of the tank container. It can be prompted a required filling of the storage tank. In the event of malfunction of the operating state, maintenance personnel can be made to examine the tank container. If in spite of all security measures If a leak occurs, an emergency service can be alerted immediately so that pollution of the environment is avoided or minimized.

By use in the track area, it is also particularly advantageous if, according to claim 17, the track at the point where the railed vehicle to be refueled is refueled against possibly dripping from the fuel nozzle fuel is secured. This is done by means of drip traps for the attachment of drip rates, which are installed at the interface vehicle tank - nozzle on the track.

• Figur 1 zeigt einen erfindungsgemäßen Tankcontainer in der Draufsicht, der zur Anschauung sowohl gerade von einem Tankkraftwagen (10) befüllt wird, als auch zum Betanken eines Schienenfahrzeugs (11) an einem Gleis verwendet wird.
• Figur 2 zeigt eine Seitenansicht des Tankcontainers.

An advantageous embodiment of the invention will be described below with reference to an embodiment and the FIGS. 1 and 2 described in more detail:

• FIG. 1 shows a tank container according to the invention in plan view, which is for the sake of both just a tanker (10) is filled, as well as for refueling a rail vehicle (11) is used on a track.
• FIG. 2 shows a side view of the tank container.

The tank container consists of a 20ft steel container, measuring 6058 mm x 2438 mm x 2590 mm, and has an empty mass of 4600 kg. In the steel container is a single-walled storage tank (1), with a capacity of 10000 liters, e.g. with a diameter of 2000 mm and a length of 3650 mm. The storage tank is mounted on a support frame (22) and contains diesel fuel for refueling rail vehicles (11).

The tank container can be closed with doors (12).

Transport is by truck with container trailer.

The tank container is placed horizontally, with the front side (doors) to the track.

The storage tank (1) is located in the container in a collecting space (4) which is sealed by a welded to the outer wall of the container partition (20). The partition (20) has a height of about 89 cm. With a width of approx. 233 cm and with a depth of approx. 515 cm this forms in the container a collecting space (4) of about 10000 l.

In order to be able to use the tank container even in remote areas without the presence of qualified personnel, a remote monitoring device is installed, with which the filling and discharge quantities as well as the installed safety devices are permanently monitored. For this purpose, a fault message module is mounted in the control cabinet (7) of the tank container. This fault message module detects and processes the signals of the installed safety devices. The relevant data is transmitted from the safety devices to so-called reporting lines. When a safety device triggers, the associated signal line triggers. That is, the mobile tank container is automatically disturbed, filling and refueling operations are no longer possible and are remotely located via a remote communication installed in the fault reporting module, e.g. a radio modem, the central service center is informed about the process and skilled personnel requested.

Leakage of the storage tank or other leaks are detected by a probe in the collecting chamber (4), which reports the occurrence of a leakage to the fault reporting module via an oil-water warning device. At the same time, the oil-water warning device also gives an optical and acoustic alarm in the event of leakage. Furthermore, all refueling operations are blocked in the event of a leak. In addition, a leak detector is used to monitor whether the double-walled refueling hose (19) is tight.

• Kommunikationseinrichtung aktiv
• NOT ― STOPP betätigt
• Spannungsausfall
• Alarm Leckanzeigegerät für die doppelwandigen Befüll ― und Betankungsleitungen
• Alarm Öl-Wasser-Warngerät
• Füllstand Tank Minimum
• Eigenüberwachung Störmeldemodul

All fault messages are forwarded by the fault message module (in FIG. 7) to a communication device (in FIG. 6), which are then transmitted via the radio network to the central service point. The following messages are planned for this purpose:

• Communication device active
• EMERGENCY STOP pressed
• power failure
• Alarm leak detector for the double - walled filling and refueling lines
• Alarm oil-water warning device
• Level tank minimum
• Self-monitoring fault message module

Outside of the catchment area (4), but still inside the container, the operating area (23) of the tank container accessible to the tank customers is. Here are both the operating units required for the operation as well as the associated electrical system, which is mounted in a small cabinet (7), which is located in the left side of the figure on the left.

The operating range (23) is advantageously monitored with an oil-water warning device. For this purpose, a grate-covered collecting space (8) is installed on the floor, in which a probe of an oil-water warning device is mounted.

Furthermore, located in the operating area (23) on the right inner wall of a fuel terminal (6) with the communication device for remote data transmission. The fuel terminal (6) is equipped with a transponder reading unit, which ensures that the dispenser (5) is only released for customers who have a valid transponder. The fuel terminal (6) records all tank data such as date, time, amount of fuel tapped, product and vehicle at the time of refueling and transmits them via the communications network to a central service point.

Under the control cabinet (7) are located in the operating area (23) a writing desk and a mailbox for delivery notes and to fill out tank receipts. Furthermore, there is the display unit of the level measuring device attached. This display unit is connected to a level probe, which measures the level in the storage tank (1).

The operating area can be closed with the outer doors (12) of the tank container.

In the collection room, the dispenser (5) is mounted on a pedestal. A 5 m long double wall hose (¾ "-1¼") (19) leads from the pump via strain reliefs (13), which is attached to the upper wall, to a breakaway coupling (24) with the nozzle. The nozzle is self-tapping. Alternatively, a full hose dry clutch could be mounted. The self-tapping nozzle closes automatically when the liquid level in the tank to be filled reaches the maximum level. In the case of refueling a vehicle fleet equipped with dry clutches, a dry clutch can be mounted on the dispensing hose instead of a dispensing valve. This allows absolutely leak-free refueling.

The double wall hose (19) is connected to a leakage warning device, which in turn is connected to the fault reporting module (in Fig. 7).

A limit switch cable (14) with plug and a deadman button (15) are mounted on the dispensing hose (19). The refueling of the rail vehicles can only be done by means of infected limit switch plug (16) on the tank to be filled. The deadman button (15) must be kept pressed during the entire refueling process. When the deadman button is released, the fueling pump in the petrol pump (5) is switched off. Furthermore, an EMERGENCY-STOP button is installed in the tank container, which interrupts the use of the tank container when actuated. In the operating area (23) is still a container in which oil binder is kept. An approved waste container also serves to take up used, oily equipment. Two fire extinguishers PG 6 are used for fire protection

On the inside of a door leaf a showcase is mounted, in which e.g. Alarm and emergency plans, licenses, emergency numbers, accident and fire data sheets and EUK notices are shown.

On the front side of the storage tank is a dome cover to which a connection for the suction line (25) of the dispenser (5) is attached. The storage tank (1) is filled via a filling line made of steel (21), which is inserted from above into the storage tank (1). Likewise, a limit switch, a level probe and a vent line (18) for the storage tank (1) are inserted from above into the storage tank (1). The limit switch serves as a filling protection. Upon reaching the maximum level of 9500 liters in the storage tank (1), which corresponds to 95% of the maximum capacity, the filling process is automatically interrupted by immersion of the level sensor in the liquid. The change in the intrinsic resistance of the limit sensor causes the shutdown of the filling pump via the aggregate control of the filling tanker.

The filling pipe of the storage tank is designed in the collecting space inside the container as a single-walled, visible steel pipe (21), DN 80, to the rear wall. In the collecting chamber (4) is the coupling point (2) with gate valve and check valve for a double-walled, 5 m long hose line (3), DN 50 - DN 75, which is used for connection to the tanker when filling. In the collecting space (4) has a shelf on which the double wall pipe (3) is stored after filling or during transport of the system.

If the container is converted during transport, the hose line (3) can be uncoupled and stored in the collecting space of the storage tank inside the container. The coupling point (2) in the collecting chamber (4) consists of an MK 80 and VK 80 coupling. The double wall duct (3) is connected to a leak detector with visual and audible alarm, which is also connected to the fault signaling module (in 7) via two floating outputs is.

The grounding of the system can be done by means of earth spike or by means of a clamp on the track.

To increase the water protection, two sumps (9) with the respective dimensions of 1000 mm x 550 mm are placed on the track for the nozzle - vehicle tank interface. The drip pans (9) are covered with walk-on gratings. They are bolted together and placed on the ground. Ableitbleche fix the trays (9) to the rails. The drip pans (9) each contain a fleece, which can hold up to 21 liters of mineral oil per drip pan and simultaneously repels precipitation water from lateral processes. Contaminated fleece discolors and can be replaced. All these installed safety devices ensure safe operation and compliance with water protection regulations.
