Description

Dangerous goods containers and procedures The present invention relates to a hazardous goods container having a roof and a base-side collecting trough that are connected to one another by side walls that are fixed to a frame. At least one sliding gate, pretensioned toward a closed position, is movably mounted on the hazardous goods container for opening and closing an opening on at least one side. The hazardous goods container also has at least one drive train comprising an electric drive and a gear, by means of which the at least one sliding gate on the hazardous goods container can be moved into an open position and into a closed position. Furthermore, the present invention relates to a method for operating a sliding gate. DE 10 2020 117 328 A1 discloses a hazardous goods container with a bottom-mounted collecting trough, a roof, and side walls connecting the collecting trough and the roof, which are fixed to a frame. The hazardous goods container has at least one sliding door to allow the container to be opened and closed in a space-saving manner. The disadvantage of the state-of-the-art hazardous goods container is that the sliding gate can only be moved by manual force. It is therefore an object of the present invention to provide an improved dangerous goods container whose sliding gate can be moved particularly easily and reliably. The present invention solves this problem with a dangerous goods container having the features of claim 1 and a method having the features of claim 16. According to the invention, the hazardous goods container has a roof and a bottom-side collecting trough which are connected to one another by means of side walls which are fixed to a frame, wherein at least one sliding gate pre-tensioned in the direction of a closed position for opening and closing an opening on at least one side is movably mounted on the hazardous goods container and the hazardous goods container also has at least one drive train which comprises an electric drive and a gear, by means of which the at least one sliding gate on the hazardous goods container can be moved into an opening position and into the The at least one drive train comprises a detachable coupling by means of which the drive and the gear can be uncoupled, and the at least one sliding gate automatically moves into the closed position when the coupling is released. This enables simple separation between the drive and the sliding gate and thus simple operation of the sliding gate both with and without the electric drive, particularly in cases where the drive fails or cannot be used, since it does not prevent the sliding door from moving automatically when uncoupled. The hazardous goods container is preferably used for the safe storage of hazardous substances, especially flammable, explosive, or environmentally hazardous substances, such as hazardous liquids or battery storage units. The coupling is released particularly when a hazardous situation exists or arises that requires the hazardous substances to be shielded by closing at least one sliding gate. The hazardous goods container preferably comprises at least one spring element and / or, for a simple design, particularly preferably a hanging weight, by means of which the at least one sliding gate is pretensioned into the closed position and moves into the closed position when the coupling is released. This allows the sliding gate to be pretensioned into the closed position particularly easily and reliably, in particular even in the event of a fire in or around the hazardous goods container. In one embodiment, the weight can comprise a holder into which at least one weight disc is inserted, so that the weight can be adapted to a mass of the sliding gate and / or a desired pretensioning force of the sliding gate in the direction of the closed position and can therefore be used particularly flexibly for hazardous goods containers of different sizes. Particularly preferably, the coupling is a magnetic coupling, in particular an electromagnetic coupling, for particularly simple and reliable decoupling of the electric drive and the transmission, for particularly versatile use. The electric drive is in particular an electric motor and has a power supply, which can be a local power supply and / or a grid or power grid. For a simple design of the clutch, the electric drive preferably comprises a first clutch partner and the transmission comprises a second clutch partner, wherein at least one of the clutch partners is displaceably mounted. More preferably, one or both coupling partners comprise teeth and / or claws which, in a coupled state of the coupling, engage with each other in particular to enable particularly effective and reliable power transmission between the drive and the transmission. In particular, the drive train comprises a control system by means of which the clutch can be placed in the coupled state, in which the clutch partners are engaged with one another, and in a released state, in which the clutch partners are disengaged from one another. Particularly preferably, the control system controls an electromagnet of the clutch that can be electrically switched on and off. This makes it particularly easy to release the clutch. Preferably, when the electromagnet is switched on or off by the control system, at least one of the clutch partners moves so that they are engaged or disengaged. In the released state, the drive and the transmission are uncoupled. Preferably, the control system can switch back and forth between the coupled and released states, in particular by means of the electromagnet. Preferably, the clutch is in the released state when the electromagnet is off. This allows the sliding gate to move even in the event of a power failure, meaning it can be closed simply by disengaging the clutch. The control system preferably comprises a monitoring device that monitors a protected area, which is an area in and / or around the hazardous goods container, and deactivates the electromagnet when a signal is detected, thereby disengaging the coupling. The monitoring device can preferably detect the signal in the event of a hazardous situation, in particular a fire or smoke or heat development in the protected area. Thus, in the event of a fire, the gear is decoupled from the drive, i.e. separated, and the sliding gate automatically moves into the closed position. If the monitoring device detects heat development, the container can, under certain circumstances, be closed even before a fire breaks out, which is particularly advantageous when storing highly flammable or explosive hazardous substances.A fire can even be extinguished by closing at least one sliding door early, especially if the hazardous goods container is airtight. For particularly reliable, simple, and cost-effective signal detection, the monitoring device can have at least one detection device for the signal, which can be an electromagnetic signal and / or a temperature change. The detection device comprises, in particular, a radar and / or a LiDAR and / or a time-of-flight system, a temperature sensor, a smoke detector, and / or an infrared camera. This also allows more than one signal to be detected, which is helpful for detecting a dangerous situation. The hazardous goods container can also have at least one sensor, which is in particular an inductive sensor and / or a light barrier, by means of which the position of the at least one sliding gate can be detected. This allows for particularly simple, computer-controlled, and remote monitoring of the position of the at least one sliding gate and whether it is closed in a situation requiring it. In a particularly preferred embodiment, the magnetic coupling can be electrically remotely switched, so that it can also be released by manual input, i.e., without triggering the monitoring device. In one variant, the coupling can also be released by applying force. The hazardous goods container optionally has a locking device comprising a linear drive, by means of which the at least one sliding door can be locked in the closed state or unlocked from this state. This advantageously allows the hazardous goods container to be locked. In particular, the magnetic coupling, the electric drive and / or the locking device can be switched by means of a radio signal, which leads to particularly versatile use and simple placement of the dangerous goods container, which in this case preferably only needs to be wired to a power supply. The at least one sliding gate preferably has a mass of 150 kg to 750 kg, and more preferably of 250 kg to 500 kg, making the hazardous goods container particularly robust. The weight, or rather the sum of the weight plates, is sufficiently high that it can still move the sliding gate. In particular, the weight is connected to at least one sliding gate via a cable pull. The side walls are preferably formed from panels having a core made of non-combustible or fire-retardant material, for example corresponding to building material class A1, and on both sides of the core, in particular sheets are provided for covering. For adjusting the closing speed of the at least one sliding gate, the drive preferably comprises at least one mechanical closing speed regulator, in particular a rotary damper, by means of which the at least one sliding gate can be moved in a controlled manner. In one embodiment, the drip tray is made of metal, but it is particularly made of a material that is resistant to the stored hazardous substances and / or heat development. At least one grating can be arranged on the drip tray, on which the hazardous substances are stored. In another embodiment, the hazardous substances container also has several levels stacked one above the other, allowing the hazardous substances to be stored in a particularly space-saving manner. A guide of the at least one sliding gate can preferably be designed as described in DE 10 2020 117 328 A1 in paragraphs

In the illustrated embodiment, the side walls 3 are arranged on three sides, while on a fourth side two sliding gates 6 and 7 are arranged, each covering an access opening to the interior of the hazardous goods container 1. Outside the hazardous goods container 1, an outer framework with vertical posts 5 is provided, which support a frame formed from profiles 4 on the roof 2. The side walls 3 are formed from panels having a core made of non-combustible or fire-retardant material, for example, corresponding to building material class A1, and metal sheets are provided on both sides of the core for covering. The drive train is concealed by a cover in Figure 1.A guide of the sliding gates 6, 7 can preferably be designed as described in DE 10 2020 117 328 A1. Figure 2 shows an internal frame 11 of the hazardous goods container 1, which is provided within the side walls 3 and the roof 2.

The weight 65 comprises a holder 652, which is displaceably guided on a guide rail 653, wherein at least one, here precisely one, weight disc 651 is inserted into the holder 651. The sliding gate 6 is connected to the weight 65 via the cable pull 68 by means of a cable shown in dashed lines, so that the sliding gate 6 is pretensioned into a closed position, in which it is shown. The cable pull 68 is designed in particular such that when the sliding gate 6 moves a certain distance, the weight 65 is offset by a correspondingly greater distance, so that when the sliding gate 6 is completely moved from an open to the closed position, the weight 65 is offset by the maximum possible distance or less. Conversely, this means that a possible offset of the weight can completely close the sliding gate if the coupling 61 is released.

Figure 4 shows an enlarged view of the drive 60 of the drive train of the hazardous goods container 1 from Figures 1 and 3, which here is coupled to the gear 67 via the clutch 61. The clutch 61 is a magnetic clutch and comprises an electromagnet 611, which is switched on in the illustrated case, so that the clutch 61 is in a coupled position. A first clutch partner 612, which is connected to the drive 60, is in engagement with a second clutch partner 613, which is connected to the gear 67, in particular to a first gear 671 of the gear 67. The first gear 671 actuates a second gear 672 via a flexible first deflection element 673, which is a belt here. The closing speed controller 66 is arranged on the second gear, by means of which a closing speed of the sliding gate 6 (not visible in Figure 3) is determined when the clutch 61 is released.The gear 67 also has a third gear 674, which is connected via a second flexible deflection element 675, here also a belt, by means of a movement mechanism not shown to the non-visible sliding gate 6 from Fig. 3 is connected, so that the sliding gate 6 can be moved by means of the drive 60 when the electromagnet 611 is switched on.
