Description

The invention relates to a container, in particular a roll-off container, settling container or ISO container, for holding flammable hazardous goods, for example electrical storage units or damaged vehicles, in particular electric vehicles, with a container bottom and several side walls that define a receiving area for the hazardous goods, at least one fluid-tight closable container opening as access to the receiving area, and a number of connections for introducing and / or discharging coolant or extinguishing agent into or out of the container.

Such a container is used, for example, to transfer hazardous goods, among other things in the form of a damaged vehicle that may have caught on fire, into the receiving area of the container and, after closing the container opening, to bring the fire under control by introducing an extinguishing agent into the interior of the container to delete. After the extinguishing process has taken place, the extinguishing agent is usually removed from the container again in order to be able to transport the container with the damaged vehicle or dangerous goods.

Out DE 10 2016 211 854 B3 For example, a container for recovering damaged vehicles is known by the present applicant.

The extinguishing agent brought into contact with the vehicle inside the container is sometimes carried along with it, for example by substances escaping from the damaged vehicle contaminated additional pollutants. The leaking substances include, for example, classic vehicle equipment, as well as the chemical components of the electrical storage cells of a vehicle battery or the thermal decomposition products that arise in the course of combustion, which would additionally pollute the environment. The ability of the container to be able to effectively fight fires inside the container and to protect the contaminated extinguishing agent in the container from escaping is therefore of the highest importance.

The invention was based on the object of providing a container for holding dangerous goods which improves the aforementioned aspects as far as possible. In particular, the invention was based on the object of specifying a container and a method for fighting fires with which the safety when handling dangerous goods, in particular while avoiding contamination of the environment, is further improved. Furthermore, the invention was based in particular on the object of further improving the fire fighting suitability of the container.

The invention achieves the object on which it is based in a container for receiving dangerous goods in a first aspect with the features according to claim 1.

In particular, it is proposed that an extinguishing agent tank be provided within the container, the extinguishing agent tank and the receiving area being connected by means of a fluid line for introducing extinguishing agent into the receiving area, a shut-off device for releasing or blocking the fluid line being arranged between the extinguishing agent tank and the receiving area. According to the invention, the approach pursued here is to enable the receiving area for the hazardous goods to be supplied with extinguishing agent from a container reservoir by means of the extinguishing agent tank integrated in the container. Instead of an external extinguishing agent supply via any connections arranged on the container, to which supply hoses have to be connected before a hazardous material is deleted in the receiving area, an independent supply of the receiving area with extinguishing agent is achieved. The transfer of the extinguishing agent from the tank into the receiving area takes place via one or more fluid lines connected to the extinguishing agent tank. At least one shut-off device is provided within the fluid line, by means of which the fluid flow of extinguishing agent in the fluid line is permitted or interrupted.

A further development of the container according to the invention provides that the receiving area has a drain opening on the bottom side and one with the drain opening Has fluid-connected pump for delivering extinguishing agent from the receiving area. After the extinguishing process has taken place, the extinguishing agent can be discharged from the receiving area via the bottom-side drain opening and, if necessary, discharged from the container via a connection for discharging coolant or extinguishing agent. A targeted removal of the extinguishing agent, which may be contaminated with harmful substances, is effected via the pump. The pump is preferably coupled to the outlet opening on the receiving area via a further fluid line, within which a shut-off device is preferably arranged for releasing or blocking the fluid line. A valve or a slide, for example, can be used as the shut-off device.

The pump can preferably be connected to the extinguishing agent tank in a fluid-conducting manner and is designed to convey the extinguishing agent from the receiving area back into the extinguishing agent tank in a fluid-conducting connection with the extinguishing agent tank. Instead of pumping the extinguishing agent out of the container after the extinguishing process, the extinguishing agent used can be fed back into the extinguishing agent tank. In particular, after the extinguishing agent has been returned to the extinguishing agent tank, the container according to the invention with the dangerous goods disposed therein can be transported away immediately. This further improves the possible uses of a container designed according to the invention in this way. In order to introduce the extinguishing agent conveyed away from the extinguishing agent tank, the pump is connected on the outlet side to an inlet opening of the extinguishing agent tank in a fluid-conducting manner.

According to a preferred development, at least one extinguishing line is provided on the container for discharging extinguishing agent into the receiving area, preferably from the roof area of the receiving area and / or from the container bottom, the pump preferably being connectable to the extinguishing line in a fluid-conducting manner and being set up to deliver extinguishing agent into the extinguishing line to promote. With the help of the one or more extinguishing lines arranged inside the container in the receiving area, a targeted introduction of extinguishing agent into the receiving area is possible. The extinguishing line has at least one outlet opening through which the extinguishing agent is introduced into the receiving area. Extinguishing lines of different lengths are preferably provided, the outlet openings of which open into different areas of the receiving area. This improves the targeted supply of extinguishing agent to hazardous goods received within the receptacle.

In a preferred embodiment, two extinguishing lines are provided in the roof area of the container, which run essentially parallel along the longitudinal side walls of the container at a distance from the edge of the roof area. The one or several extinguishing lines on the container base run preferably parallel to the longitudinal axis above the container base. In a further embodiment of the invention, the extinguishing line can be integrated into the container bottom with the top of the container bottom without a step. In this way, the extinguishing line arranged on the floor does not form an obstacle on the floor.

According to a further development of the container according to the invention, the pump is set up to recirculate extinguishing agent from the receiving area via at least the extinguishing line into the receiving area. By means of the constant conveyance of the extinguishing agent in a circuit, the extinguishing effect on the container according to the invention is improved and, furthermore, the required amount of coolant or extinguishing agent can advantageously be reduced. A saving in extinguishing agent to be introduced into the container according to the invention is thus achieved. The extinguishing agent is preferably discharged from the receiving area via the drain opening into a collecting area corresponding to the receiving area, similar to a pump sump. The pump is or can be connected in a fluid-conducting manner to the collecting area, from which the pump introduces the extinguishing agent into the extinguishing line connected to it and again into the receiving area.

The extinguishing agent tank is preferably arranged in the front wall of the container and preferably has an extinguishing agent volume of 2000 m ³ or more, more preferably 2500 m ³ or more, particularly preferably 3000 m ³ or more. By means of the existing volume of extinguishing agent, a safe fire fighting of a hazardous material arranged within the receiving area is effected.

According to a further embodiment of the container according to the invention, the extinguishing agent tank is a first extinguishing agent tank, and the container also has a second extinguishing agent tank, which is arranged below the receiving area. The second extinguishing agent tank preferably has an extinguishing agent volume which is equal to or greater than the extinguishing agent volume of the first extinguishing agent container. The second extinguishing agent container further preferably has an extinguishing agent volume of 3000 m ³ or more, particularly preferably of 3500 m ³ or more.

The volumes of the receiving area and the extinguishing agent tank (s) are matched to one another such that a minimum height of extinguishing agent of about 60 cm or more is achieved by flooding the receiving area from preferably one of the extinguishing agent tanks within the receiving area. A hazardous material located in the receiving area, such as a vehicle battery installed in a vehicle with an electric drive, thus comes into direct contact with the coolant or extinguishing agent. The container preferably has an inlet on its end wall delimiting the receiving area on the inside, which inlet can be connected in a fluid-conducting manner via the pump to the first and / or second extinguishing agent tank for flooding the receiving area.

The pump can preferably be connected in a fluid-conducting manner to the second extinguishing agent tank and is designed to convey extinguishing agent back and forth between the first extinguishing agent tank and the second extinguishing agent tank. Thus, the introduction of extinguishing agent into the receiving area or the discharge of the extinguishing agent from the receiving area into the extinguishing agent tanks and the possibly necessary distribution of the extinguishing agent between the first and second extinguishing agent tanks is possible with just a single pump. In addition, only a single inlet is preferably provided for flooding the receiving area with extinguishing agent and only one outlet opening for the extinguishing agent on the receiving area.

According to a preferred development of the container according to the invention, the pump is a first pump and the container furthermore comprises a second pump which can be connected to the second extinguishing agent tank in a fluid-conducting manner and is configured to convey extinguishing agent back and forth between the first extinguishing agent tank and the second extinguishing agent tank. The use of two pumps enables efficient operation of the container according to the invention, since with the synchronous operation of the two pumps, various work steps, such as introducing extinguishing agent into the receiving area and diverting the extinguishing agent from one extinguishing agent tank to the other, can be carried out at the same time.

Particularly preferably, the second pump can be connected to the extinguishing line in a fluid-conducting manner and is configured to convey extinguishing agent from the second extinguishing agent tank into the extinguishing line and further preferably to convey extinguishing agent from the receiving area via at least the extinguishing line back into the receiving area in the circuit. The supply of extinguishing agent from, for example, the extinguishing line and the receiving area is thus possible independently of one another from both extinguishing agent tanks. The extinguishing agent is preferably introduced via an inlet line and the extinguishing agent is discharged from the receiving area via a discharge line, which are each connected to the first and second extinguishing agent tanks via corresponding connecting lines. The fluid flow can be released or interrupted by means of corresponding shut-off devices arranged in the connecting lines.

The container according to the invention is also characterized by a sensor unit for detecting fire parameters in the interior of the receiving area, the Sensor unit is preferably set up to output an alarm when a fire parameter is detected. In particular in the case of electric vehicles that are contained within the container as hazardous goods, there is the possibility of re-ignition, which is detected by the sensor unit. When corresponding fire parameters are detected within the recording area, an alarm is output in the form of at least one electrical signal. With the aid of the electrical signal, for example, a signal transmitter can be controlled, which for example outputs an optical or an acoustic signal as a warning message.

According to a preferred development, the container comprises a control device, which is connected to the sensor unit and to the pump or, in the case of several pumps, for example 2 pumps, to the first and / or second pump in a signal-conducting manner and is set up to respond when a fire parameter is detected by the sensor unit, which To control the pump or pumps for pumping extinguishing agent into the receiving area of the container. In particular, after a first extinguishing process and the return of the extinguishing agent to the extinguishing agent tank, the extinguishing agent that has already been used can be reintroduced from the extinguishing agent tank into the receptacle area of the container when a re-ignition of the dangerous goods still in the receiving area is detected. The extinguishing agent is introduced, for example, by flooding the receiving area and / or conveying the extinguishing agent in the circuit from the receiving area via the pump into the one or more extinguishing lines that are fluidly connected to the pump on the outlet side again into the receiving area.

According to a preferred development, a number of connections are provided on the container for introducing and / or discharging coolant or extinguishing agent into or out of the container, with one or more connections for feeding and discharging extinguishing agent into or from the receiving area, preferably. the first tank and / or the second tank are provided. With the help of the connections on the outside of the container according to the invention, extinguishing agent can be introduced externally into the container, preferably its extinguishing agent tank, for the first filling of the container, and extinguishing agent already used can be discharged from the container for proper disposal. In one version, extinguishing agent is introduced directly into the extinguishing lines via one or more connections. The connections for discharge are preferably arranged close to the bottom of the container. The connections for introducing the extinguishing agent are approximately halfway up the container. All connections for introducing and / or discharging extinguishing agent into or out of the container are preferably equipped with Storz couplings. According to a development of the container according to the invention, at least one plug-in bulkhead is preferably provided within the receiving area, which is designed to be inserted in a fluid-tight manner into a plug-in location, preferably parallel to the opening plane of the container opening. By means of the plug-in bulkhead, a sealing function can be achieved within the receiving area in addition to the closable container opening. The escape of extinguishing agent from the receiving area of the container according to the invention is prevented even when the container opening is open. The plug-in bulkhead preferably runs parallel to the opening plane of the container opening. In one embodiment of the container with a container opening on one end face, the plug-in bulkhead extends essentially transversely to the longitudinal axis of the container. In a further embodiment with a container opening on one longitudinal side, which is preferably aligned parallel to the container longitudinal axis, such a plug-in bulkhead extends parallel to the container longitudinal axis. In the present case, the longitudinal axis of the container is to be understood as the central axis of the container, which runs essentially between the long side walls of the container.

According to a preferred embodiment of the container according to the invention, a plurality of slots for the plug-in bulkhead, which subdivide the receiving area in the longitudinal direction of the container into partial areas, are provided within the receiving area. The plug-in bulkhead can thus preferably be arranged at different positions within the receiving area and the receiving area can be divided into several sub-areas. In the separate areas of the receiving area, different hazardous goods can be stored whose contact with one another is to be avoided. In addition, by dividing the receiving area into several partial areas, there is the possibility of introducing the extinguishing agent in a targeted manner into only a certain partial area of the receiving area. The slot adjacent to the container opening is arranged such that the door or flap sealing the container opening can also be closed when the plug-in bulkhead is inserted.

Another development of the invention provides that a plug-in bulkhead can be assembled from a plurality of wall elements in the slot, with at least one sealing element preferably being arranged between two wall elements. The plug bulkhead according to the invention is thus variable in height. In addition, a plug-in bulkhead made of several composable wall elements has the advantage over a one-piece plug-in bulkhead that it is easier to handle during assembly inside the container. The plug-in bulkhead is formed from two, three, four, five or more wall elements. The plug-in bulkhead preferably extends over at least 1/3 of the total height of the container, with a smaller height due to the multiple wall elements that can be assembled is possible. A completely assembled plug-in bulkhead preferably has a height of approximately half the total height of the container.

The wall elements preferably have at least mutually corresponding form-locking elements on their longitudinal sides that can be brought into contact with one another. With the aid of the form-fit elements, the wall elements are mechanically coupled to one another, as a result of which the bulkhead composed of the wall elements has increased rigidity in its plane and thus an improved resistance to the active extinguishing agent pressure.

In a preferred embodiment of the container, the slot has two inserts for the plug-in bulkhead, which are arranged on opposite side walls of the container. The inserts extend in a substantially vertical direction to the container bottom. The slots of the slot are designed like rails and have one or more sealing elements for laterally sealing the wall elements in the slots.

A hold-down device for locking the plug-in partition within a slot is preferably assigned to each plug-in bulkhead. This causes a sealing contact between the lower edge of the plug-in bulkhead, which has a sealing element, and the upper side of the container bottom and the adjacent wall elements with one another.

The extinguishing line preferably has a plurality of outlet openings arranged distributed along the line. With the aid of the outlet openings formed on the extinguishing line, extinguishing agent is discharged within the receiving area or a partial area of the receiving area over the largest possible volume of space. The outlet openings are preferably set up to generate a spray mist which causes the hazardous goods received in the container to be wetted as evenly as possible. In a preferred embodiment, the outlet openings are designed with a metallic pipe as an extinguishing pipe as bores in the wall of the pipe. In a further embodiment, the outlet openings are designed as extinguishing nozzles which are arranged in the wall of the extinguishing line.

The preferred embodiments of the container according to the first aspect described above are also preferred embodiments of the second aspect and vice versa. In this regard, to avoid repetition, reference is made to the above statements.

With the aid of the loading ramp, the difference in height between the container floor and the ground outside the container is preferably bridged and thus the loading of hazardous goods into the receiving area of the container is simplified. The reversibly mountable loading ramp is to be understood as a loading ramp which can preferably be attached to the container as often as desired in the area of the container opening.

A holder for coupling the loading ramp to the container is preferably provided in the region of the container opening. In a preferred embodiment of the invention, the loading ramp is formed from two loading rails that can be positioned at a distance from one another on the container opening. The loading ramp, in particular the two loading rails, are preferably suspended in a form-fitting manner in holding rails formed on the container. One end of the loading ramp or each of the loading rails preferably has a hook part which engages in the holding rails on the container. To During the loading process, the loading ramp or the loading rails can easily be separated from one another by releasing the form fit between the retaining rail and the hook part on the loading ramp / the loading rails.

According to a further development of the container according to the invention, the container has receptacles for the loading ramp, which are formed on the double doors that can be closed off the container opening or on the underside of the container. In this way, the loading ramp can preferably be carried along with the container, so that the loading ramp can always be mounted in the area of the container opening when it is required for loading hazardous goods in the receiving area of the container. The two loading rails are arranged via their hook parts on the insides of the two wing doors closing the container opening and are preferably fixed to them. In an optional or alternative embodiment, the receptacle for the loading ramp, which consists, for example, of two loading rails, is formed on the underside of the container. The receptacle for the loading ramp preferably has openings on the underside of the container that are accessible from its longitudinal sides for removing and / or introducing the loading ramp. The receptacles extend in particular transversely to the longitudinal axis of the container. This prevents the loading ramp from being inadvertently moved out of the receptacle when the container is picked up or set down.

According to a preferred development of the invention, two drivable floor elevations are provided which are arranged adjacent to the container opening on the sides of the receiving area. When transferring, for example, a damaged vehicle into the receiving area of the container, the vehicle does not land in the area of the container opening with the underbody. This counteracts any possible hindrance to the recovery process of the vehicle. The raised areas extend, starting from the side walls, preferably over a third of the width of the container base and, starting from the container opening in the longitudinal direction of the container, over about a fifth of its length.

The raised floor areas are preferably designed as a kind of grid and are pivotably articulated in the transition to the side walls and are designed to be moved back and forth between a stowed position approximating the side walls of the container and an access position approximating the container base. The raised floors have a vertical orientation in the stowed position. In use, that is to say in their drive-on position, the raised floors have an essentially horizontal orientation. The raised floors, which are preferably several centimeters thick, can be locked in their vertical alignment with the aid of a safety device in the stowed position. According to a preferred development of the container, a roof extending along the side walls is provided, the roof preferably being designed as a fixed roof, as a reversibly detachable hard top, or as a reversibly detachable tarpaulin roof. With the solid design of the roof, the container has a corresponding fire resistance. In particular in the event of a fire inside the container, the escape of smoke gases from the receiving area of the container is significantly reduced. In a preferred embodiment, the roof is designed as a tarpaulin roof made of fire-resistant fabric. In a preferred embodiment, flat textile structures with a temperature resistance of preferably up to 1600 ° C. are used as the tarpaulin material for the tarpaulin roof.

In connection with a tarpaulin roof extending along the side walls of the container, a removable crosshead is provided in the area of the container opening, which simplifies the accessibility of the container by means of a forklift for bringing in the hazardous goods to be stored in the receiving area of the container.

A winch arranged on the container is preferably provided, in particular a cable winch, for bringing dangerous goods into the container. With the aid of the winch, for example, a damaged vehicle can be moved into the receiving area of the container via the container opening. The winch is preferably fastened directly to the inside of the side wall arranged opposite the container opening. The winch is preferably arranged at a distance of at least 1 m above the container bottom. In a further embodiment, the winch used has a degree of protection of at least IP56 (in accordance with DIN EN 60529) or higher to protect its electrical components.

According to a third aspect, which is at the same time an independent aspect of the invention and a preferred embodiment of the container according to the first and / or second aspect, the present invention relates to a container in which a container receiving hook is arranged on the outside of a side wall of the container, which in a recess is made in the side wall.

In other words, the third aspect relates to a container, in particular a roll-off container, settling container or ISO container, for holding flammable hazardous goods, for example electrical storage units or damaged vehicles, with a container base and several side walls that define a receiving area for the hazardous goods, at least one fluid-tight closable container opening as access to the receiving area, and a number of connections for introducing and / or Discharge of coolant or extinguishing agent into or out of the container, a container receiving hook being arranged on the outside of a side wall of the container, which hook is let into a recess in the side wall.

The preferred embodiments of the container according to the first and second aspects described above are at the same time preferred embodiments of the container according to the third aspect and vice versa, for which reason reference is made in this regard to the above statements to avoid repetition.

The container receiving hook preferably does not protrude beyond the outer dimensions of the container. This enables several such containers to be stacked or arranged one behind the other on a transport vehicle.

In a preferred development, the receiving hook can be reversibly pivoted back and forth between a working position and a rest position. With the help of the pivotable design of the container receiving hook, the recess on the outside of the side wall can be made smaller. As a result, the inside of the front side wall jumps back less into the receiving area of the container. The container receiving hook can be pivoted as often as desired from its rest position into its working position and back into its rest position. The container receiving hook can be locked in its working position and its rest position. Unintentional pivoting out of its working position into the rest position or in the opposite direction is thus avoided.

According to a fourth aspect of the present invention, which is at the same time a separate aspect of the invention and a preferred embodiment of the first three aspects, a container is provided in which, according to the invention, two or more rollers are provided on its container bottom for moving the container, the rollers folding or are designed to be pivotable on the underside of the container and can be moved back and forth between a working position and a rest position.

The fourth aspect thus relates to a container, in particular roll-off containers, settling containers or ISO containers, for receiving flammable hazardous goods, with a container base and several side walls that define a receiving area for the hazardous goods, at least one container opening that can be closed in a fluid-tight manner as access to the receiving area, and in the According to the invention, two or more rollers for moving the container are provided on its container underside, the rollers being designed to be foldable or pivotable on the container underside and being movable back and forth between a working position and a rest position.

The preferred embodiments of the first three aspects described above are at the same time preferred embodiments of the fourth aspect and vice versa, for which reason reference is made in this regard to the above statements to avoid repetition.

An otherwise usually stackable container, which is equipped by means of rollers designed according to the invention in this way, can be moved over the ground in a simplified manner with the aid of the container receiving hook. The rollers are preferably arranged at the end of the container opposite to the receiving hook. With the pivotable configuration, the rollers can be pivoted on the underside of the container in such a way that they do not protrude beyond the outer dimensions of the container, which is preferably designed as a 20 'ISO container. Thus, the loading and transportability of the container according to the invention on the other various common transport routes is not impaired. Such a container designed according to the invention is preferably also stackable on top of one another.

In a preferred embodiment of the container according to the invention it is provided that at least one electrical connection for the power supply of the winch and / or the pump is provided on one of the side walls. With the help of the electrical connection, the winch or the pump is preferably operated in the receiving area for the extinguishing agent. A plurality of electrical connections are preferably provided, one of which can be used to connect a remote control for controlling the winch arranged inside the container. A lockable control cabinet, within which the one or more electrical connections are arranged, is preferably arranged on the outside of the side wall having the container receiving hook.

According to a further development, the container according to the invention has an energy store, by means of which the winch or the pump can be operated independently for a predetermined period of time. In particular in the case of a container with an extinguishing agent tank integrated therein, which is parked with a hazardous material located in its receiving area, the extinguishing agent from the extinguishing agent tank can be repeatedly introduced into the receiving area in the event of a possible re-ignition of the hazardous material in the receiving area. An automatic extinguishing function can thus be implemented by means of the container according to the invention.

In a further aspect, the present invention relates to a method for fire-fighting dangerous goods in a container, in particular in a container according to one of the preceding claims.

The invention solves the problem identified at the outset with the following steps: bringing the hazardous goods into a receiving area in the interior of the container, and introducing extinguishing agent into the receiving area from an extinguishing agent tank arranged in the container. The invention makes use of the knowledge that, with the introduction of extinguishing agent from an extinguishing agent tank in the container, an autarkic supply of the container is achieved during the fire fighting of a hazardous material received in the receiving area at least over a predetermined period of time. Thus, such a container according to the invention is ready for use immediately after it has been set down at the place of use. In contrast to the container known from the prior art, no separate supply of extinguishing agent is required.

The method according to the invention is preferably developed further by the step of conveying the extinguishing agent away from the receiving area, preferably after the fire fighting has taken place, back into the extinguishing agent tank. After a successful extinguishing process, the extinguishing agent used is not discharged directly from the container, but is returned to the extinguishing agent tank and at least temporarily stored there. The extinguishing agent is conveyed away from the receiving area and introduced into the extinguishing agent tank by means of at least one pump.

According to a preferred development, the method comprises the step of: dispensing extinguishing agent into the receiving area by means of an extinguishing line arranged in the container, and preferably conveying extinguishing agent in the circuit from the receiving area via at least the extinguishing line back into the receiving area. By conveying the extinguishing agent in the circuit, a steady flow of extinguishing agent and contact of the extinguishing agent with the dangerous goods in the receiving area of the container is achieved. In particular, a spray mist can be generated within the receiving area via the extinguishing agent output via outlet openings on the extinguishing lines. The temperature in the receiving area is preferably cooled down by the spray mist. In addition, the efficient use of the extinguishing agent is achieved by conveying the extinguishing agent in the circuit within the container, which leads to a saving in the amount of extinguishing agent required in contrast to a container that is only supplied with extinguishing agent from outside.

In a preferred embodiment, the method according to the invention comprises the step or steps: Monitoring the hazardous goods in the receiving area for the occurrence of a fire by means of a detection of fire parameters, and in the case of detection of a fire parameter, output of an alarm signal and / or application of extinguishing agent into the receiving area by means of an extinguishing line arranged in the container or a fluid line for flooding the receiving container, and preferably conveying (or re-conveying) the extinguishing agent in the cycle. The detection of fire parameters within the receiving area has the advantage that a renewed ignition of the hazardous goods within the container is detected and appropriate countermeasures can be initiated. When a fire parameter is detected, an alarm signal, preferably in the form of an electrical signal, is output to, for example, a control device in the container. After such an alarm signal is detected, extinguishing agent is preferably discharged from the extinguishing tank into the receiving area of the container or introduced therein. The discharge or introduction takes place preferably by means of an extinguishing line arranged in the container or a fluid line for flooding the receiving area. The method preferably provides for the delivery or renewed delivery of the extinguishing agent in the circuit. The conveying in the circuit includes at least conveying the extinguishing agent from the receiving area via at least the extinguishing line in the container and introducing it again into the receiving area. With the aid of the method steps according to the invention, an automatic extinguishing function can be implemented with the container according to the invention.

In addition, the wall elements have on their longitudinal sides which can be brought into contact mutually corresponding tongue and groove connection. The lowermost wall element 20 is equipped with a seal that can be brought into contact with the container bottom 2 in a sealing manner.

Fig. 2 shows the container 1 according to the invention in section, whereby its further structure is illustrated in more detail. In the present embodiment, the container 1 has a plurality of slots 18 ', 18 "for the plug-in bulkhead 16, dividing the receiving area 12 in the longitudinal direction of the container 1 into partial areas. Three slots are shown here, the number of which, however, vary between a number between 1 and 5 Each slot 18, 18 ', 18 "has two inserts 22 for the plug-in bulkhead 16, which are arranged on opposite side walls of the container. The inserts 22 are designed as receiving rails with legs running parallel to one another, into which the wall elements 20, 20 'of the plug-in bulkhead are guided laterally in the vertical direction in a respective slot when inserted. Each insert 22 can also be equipped with one or more sealing elements.

As from the Fig. 1 and 2 Furthermore, it can be seen that extinguishing lines 24, 24 ', 26 are arranged in the receiving area 12 of the container 1, which conduct fluid with a connection 28 for introducing fluid into the container 1 ( Fig. 3 ) are coupled in a fluid-conducting manner. In one embodiment of the container according to the invention, the extinguishing fluid lines 24, 24 'run along the upper edge of the opposite side walls 4, 4'. At least one extinguishing line 26 is integrated into the container bottom 2 in such a way that it terminates with the top of the container bottom 2 without a step. In a further embodiment, not shown, one or more extinguishing fluid lines are arranged on the container bottom 2 and run in the longitudinal direction. The extinguishing fluid lines 24, 24 ′, 26 are coupled to a distributor line 30 to which the connection 28 is connected. The extinguishing fluid lines have a plurality of outlet openings 32 distributed along the line. The outlet openings 32 can be designed as bores in the extinguishing lines 24, 24 ', 26 or as nozzles mounted on the extinguishing line.

Like that Fig. 2 and 3 As can be seen, a plurality of connections 34, 34 'for extinguishing hose connections that can be coupled therewith are arranged in the receiving area 12 of the container 1, which are arranged adjacent to the front side wall 6 or at the ends of the extinguishing lines 24, 24'. By means of an actuatable shut-off element 35, the fluid flow in the direction of the connections 34, 34 'can be released or interrupted. Furthermore, in the area of the container opening, the container 1 comprises a reversibly mountable loading ramp 36 made up of two loading rails 38 over which hazardous goods 11, such as for example the vehicle shown ( Fig. 1 ) are transferred into the receiving area 12 of the container 1. To couple the loading ramp 36, holding rails 40 are mounted on the outside of the container in the region of the container opening, into which a respective loading rail 38 can be suspended.

Furthermore is how out Fig. 1 It can be seen, on the double doors 14 which can be closed the container opening 10, a receptacle 42 is provided for the loading rails 38 which can be suspended on the inside of the double doors 14. The loading ramp 36 can thus be transported away together with the container 1. In an embodiment not shown in detail, the receptacles for the loading ramp are arranged on the underside of the container floor.

Further are how Fig. 2 illustrates, in the receiving area 12 of the container 1 adjacent to the container opening 10, raised areas 44 can be arranged at least in regions on the container floor. The raised floors 44 simplify the loading of vehicles with restricted ground clearance. The raised floors are designed as a type of grid and are pivotably articulated in the transition between the container wall 2 and the side walls 4, 4 '. The raised floor areas 44 can be moved from a stowed position approximated to the side wall, in which these have a vertical orientation, into the position shown in FIG Fig. 2 The approach position shown, approximating the container bottom 2, in which the latter are essentially horizontal, are moved.

How Fig. 3 clarified, a number of connections 28, 46, 46 'are arranged on the outside of the end wall, via which extinguishing agent can be introduced into the container and / or coolant or extinguishing agent can be discharged from the container 1. The connection 28 serves to supply extinguishing agent into the distribution or extinguishing lines 24, 24 ', 26, 30 arranged thereon. The connection 46 is used to introduce extinguishing agent directly into the receiving area 12 of the container 1, with which the receiving area can be flooded . The extinguishing agent can be discharged from the receiving area 12 of the container 1 by means of the connection 46 ′ at the level of the container bottom 2.

As from the Figures 3 and 4 As can be seen, a container receiving hook 48 is arranged on the outside of the end face of the container 1 and is let into a recess 50 in the side wall 6. The receiving hook 48 thus does not protrude on the outside of the front side wall 6. A container specified in this way can be used as an ISO container and is designed to be stackable with other containers via its standardized container corners 52.

For loading wrecked vehicles in particular, how Fig. 4 shows, a winch 53 is arranged in the receiving area on the inside of the side wall 6. With the aid of the cable winch 53, a vehicle or any other hazardous material 11 can be brought into the container 1. The container 1 also has how Figures 5a and b show, on the underside of the container, adjacent to the container opening 10, two rollers 54 for moving the container 1. The container 1 designed as an ISO container can thus also be used as a roll-off or deposit container. The rollers 54 are arranged on the underside of the container so that they can be folded or pivoted and, like Fig. 5 made clear to be moved reversibly back and forth between a working position and a rest position. The container 1 has a corresponding recess 56 in the container base 2 for the rollers 54 which are folded in in the rest position. The role 54 is, see Figure 5b , secured with the help of a manually operable locking pin 58 in the respective working or rest position.

The extinguishing agent is distributed with the aid of a pump 66, which can be coupled in a fluid-conducting manner directly to the extinguishing agent tanks 62, 64 or also to a collecting area 68 formed on the container bottom for the extinguishing agent released into the receiving area 12 for the hazardous material. The pump 66 is set up to discharge the extinguishing agent from the collecting area 68 in a manner To convey the extinguishing agent cycle again into the receiving area 12 via the extinguishing lines 24, 24 ', 26.

As from the Figures 6 to 8 furthermore, the receiving hook 48 is arranged on the outside of the side wall 6, via which the container 1 'can be picked up on its loading area by a transport vehicle, in particular a swap-loader vehicle, or set down at the place of use. In addition, the container 1 ′ also has a cable winch 53 arranged on the end wall 6 in the receiving area 12. Furthermore, the container 1 comprises a plurality of connections 28, 46, 46 ', 70 arranged on the outside of the end wall, via which the extinguishing agent is either introduced directly into the receiving area 12 or into the extinguishing lines 24, 24', into the extinguishing agent tanks 62, 64 or can be drained from the receiving area 12 or the extinguishing agent tanks 62, 64. Extinguishing agent is introduced externally into the receiving area 12 via the connection 46 and a fluid line 72 connected to it.

The pump 66 is a first pump which is set up to transfer extinguishing agent from one of the extinguishing agent tanks 62, 64 via a fluid line 74 via the extinguishing lines 24, 24 ′ into the receiving area 12. Furthermore, a fluid line 76 and a shut-off element 80 arranged in the fluid line 76 are provided on the container 1 ', via which extinguishing agent is introduced from the extinguishing agent tank 62 directly into the receiving area 12 of the container 1' and the receiving area 12 is thus flooded. How Fig. 8 As further illustrated, the extinguishing agent can be diverted from the extinguishing agent tank 64 in the bottom of the container 1 to the extinguishing agent tank 62 in the end wall of the container 1 'by means of a second pump 66' and a fluid line 78 connected on the outlet side.
