Definitions

  • the invention relates to a safety cabinet, in particular a fire protection cabinet for holding hazardous substances, preferably a battery cabinet for holding and storing high-performance batteries such as lithium-ion batteries, with a cabinet body and at least one cabinet door connected to or interacting with the cabinet body, and with at least one in the cabinet body arranged sensor whose sensor signals are evaluated by a control unit.
  • a safety cabinet in particular a fire protection cabinet for holding hazardous substances, preferably a battery cabinet for holding and storing high-performance batteries such as lithium-ion batteries, with a cabinet body and at least one cabinet door connected to or interacting with the cabinet body, and with at least one in the cabinet body arranged sensor whose sensor signals are evaluated by a control unit.
  • Safety cabinets and fire protection cabinets in general are typically used to hold hazardous substances such as liquid and flammable chemicals. But it can also be stored inside, for example, gas bottles or solid hazardous substances.
  • the safety cabinets or fire protection cabinets In order to protect the hazardous substances from any external sources of fire, the safety cabinets or fire protection cabinets have a specified fire resistance, which corresponds to different fire resistance periods.
  • the fire protection cabinets in question are usually classified according to DIN EN14470. A total of four levels of fire resistance periods of 15 minutes, 30 minutes, 60 minutes and finally 90 minutes are differentiated, as exemplified in the utility model DE 20 2014 101 935 U1 the applicant is described.
  • a fuse provided inside the safety cabinet ensures that the respective cabinet door or the multiple cabinet doors are automatically closed in the event of a fire. Because then she speaks Fuse and ensures the closure of the revolving door in question, as for example in the prior art according to the US 6,250,015 B1 is described.
  • a locking element on the swing door is transferred into its locked state.
  • the locking element is connected to a spring.
  • a door closing mechanism is then activated to press at least one door as soon as a temperature sensor detects an impermissible temperature increase near the safety cabinet.
  • the door closing mechanism is normally not coupled to the door and only ensures that it is activated as soon as the temperature sensor reacts.
  • an automatic locking system for fireproof cabinets is described.
  • This consists of an electromagnetically lockable door closer and an automatic locking mechanism.
  • the door closer pulls the door shut, at the end of which the automatic locking mechanism engages and locks the door.
  • the lock can be released again by hand using a locking mechanism.
  • the sensor for emitting and transmitting the sensor signals to the control unit is one that measures the amount of air flowing through an exhaust air line.
  • the amount of air extracted from the inside of the cabinet body can be controlled with the aid of the control unit.
  • a locking mechanism engages with a tension member on a door of the cabinet.
  • a power source for the tension member for closing the door can be locked with the aid of a magnetic clamp controlled by a signal.
  • the holding magnet can be triggered by a signal.
  • the power supply to the holding magnet can be interrupted via a smoke or fire sensor or some other hazard alarm. In this way, the power source or a gas spring becomes effective and ensures that the door is closed by the force of the gas spring.
  • safety cabinets have also increasingly been used to store batteries and, in particular, high-performance batteries such as lithium-ion batteries.
  • the safety cabinet in question is preferably a battery cabinet.
  • battery cabinets exist in the prior art according to DE 101 14 960 C1
  • the invention is based on the technical problem of further developing such a safety cabinet in such a way that sources of fire that arise in the cabinet interior in particular can be controlled easily and reliably.
  • a safety cabinet according to claim 1 is provided.
  • at least one electronic sensor arranged in the cabinet body is used first of all.
  • the sensor signals generated by the electronic sensor in question are evaluated by the control unit. Any mechanical solutions as in the prior art according to the DE 35 27 287 A1 or according to the EP 0 170 337 A1 are therefore expressly not implemented.
  • the control unit By resorting to the electronic sensor and the corresponding sensor signals generated by it, a very specific evaluation of the respective sensor signal can be carried out by the control unit.
  • the relevant sensor signal of the sensor can thus be evaluated to determine whether at least one threshold value is exceeded. If the sensor in question is, for example and advantageously, a temperature sensor, the threshold value in question corresponds to a limit temperature.
  • the control unit derives the locking signal as a result and this locking signal in turn ensures that the door of the cabinet body is closed or - if it is already closed - remains closed. In addition, the door may be locked.
  • the safety cabinet according to the invention and preferably the battery cabinet is closed or remains closed in any case if, for example, a fire develops inside, which in the present case corresponds to the sensor designed as a temperature sensor exceeding the previously set limit temperature .
  • threshold values can also be used at this point. That is, as soon as the sensor signal in question exceeds, for example, a first limit value and then a second limit value or a first limit temperature and then a second limit temperature, this is interpreted as a closing signal by the control unit.
  • This closing signal can be evaluated in such a way that the control unit acts on a door closing mechanism when the closing signal is present.
  • the door closing mechanism in turn ensures that the cabinet door or the multiple cabinet doors are closed. Of course, the door or cabinet door in question remains closed in the event that it has already assumed this state when the closing signal is present.
  • the door locking mechanism then practically ensures an additional locking of the door or the cabinet door.
  • the sensor signal in question or its increase over time in the example case described leads to the control unit from exceeding the limit value for the gradient (more than 20% increase in the sensor signal within 10 Seconds) derives the closing signal.
  • the control unit acts on the door closing mechanism as described.
  • the cabinet door assigned to the cabinet body is closed at an early stage and prevents a fire that develops inside the safety cabinet from spreading to the outside at all.
  • the fire can possibly also be "smothered" by closing the cabinet door.
  • the control unit when the closing signal is present, not only acts on the door closing mechanism, but optionally also on an exhaust air unit.
  • the closing signal is interpreted to the effect that not only a possible source of fire inside the safety cabinet has to be closed to the outside, but at the same time an additional exhaust air unit, if applicable, is activated in order to dissipate any vapors inside the safety cabinet. This can be done in addition to acting on the door locking mechanism.
  • the cabinet body is divided inside into at least two segments, each with an assigned sensor.
  • the respective segment can be a transverse segment.
  • transverse segmentation generally takes place, although longitudinal segmentation or both longitudinal and transverse segmentation of the cabinet interior or its cabinet body is of course also possible and encompassed by the invention.
  • the invention is based overall on the knowledge that a safety cabinet designed, for example, as a battery cabinet is typically equipped inside with several pull-out drawers and / or shelves in order to store or open the individual batteries, in particular lithium-ion batteries, in the relevant drawers to stock the shelves. So that a possible source of fire can be precisely determined in such a case, a respective sensor is assigned to each transverse segment in the example. If the sensor is a temperature sensor, it detects an increase in the temperature inside the cabinet body, specifically separately for the respective transverse segment.
  • the safety cabinet according to the invention can not only react in advance to future sources of fire that occur only locally, but the possible source of fire can also be localized in this way.
  • the sensor of which led to a closing signal from the control unit the source of the fire can be located locally inside the cabinet body and, for example, graphically displayed on a screen connected to the control unit.
  • the overall design is such that the control unit causes the door to close as soon as the sensor signals from just one of the sensors are interpreted as a closing signal by the control unit.
  • the control unit evaluates the individual sensor signals of the sensors assigned to the segments with regard to the exceeding of at least one threshold value and / or a limit value of temporal gradients in the sense of an "OR" link. As soon as at least one of the sensors or the sensor signals generated by it meet the criterion that the threshold value is exceeded and / or the predetermined limit value of temporal gradients of the sensor signal, this is interpreted by the control unit as a whole as a closing signal. As described above, when the relevant closing signal is present, the control unit acts on the door closing mechanism and possibly the exhaust air unit.
  • the "OR" link between the individual sensor signals from the sensors in the relevant segments ensures that, in the example, every local temperature excess leads to the door being closed. Of course, this is all the more true in the event that several local excess temperatures are recorded.
  • the sensors in question are advantageously each connected to the inside of the cabinet body.
  • the sensor is advantageously a temperature sensor.
  • the sensor can alternatively or additionally also be designed as a smoke, gas and / or steam sensor. In this case, excessive smoke, gas or steam development is detected by the sensor inside the cabinet body and - as with the temperature sensor - leads to a closing signal.
  • the senor can also be a leakage sensor.
  • the sensor includes any leaks, for example from hazardous material containers stored inside the cabinet body. As soon as the leakage exceeds a certain threshold value, this is again interpreted by the control unit as a closing signal and leads to the control unit acting on the door closing mechanism.
  • the sensor can also be designed as a door closing sensor. In this case, the sensor also monitors the functional state of the cabinet door, namely to determine whether it is open or closed with respect to the cabinet body.
  • the door closing mechanism is usually equipped with an automatic door closer.
  • the automatic door closer is triggered when a closing signal is present.
  • the door closing mechanism has at least one electromagnet acted upon by the control unit.
  • the electromagnet holds the cabinet door indirectly or directly against the force of a spring in the open position.
  • the door closing mechanism is advantageously also equipped with a locking element.
  • the locking element is kept in its unlocked position throughout.
  • the locking element only assumes its locked position when there is a closing signal. This can be done with the aid of a spring.
  • the result is a safety cabinet and, in particular, a battery cabinet that is predestined for storing lithium-ion batteries. This is because spontaneous ignition or fires associated with the storage of such batteries are controlled effectively and automatically.
  • the safety cabinet according to the invention evaluates signals from a single sensor or from several sensors and in particular temperature sensors present in the interior of the cabinet body.
  • the closing signal causes the control unit to act on a door closing mechanism.
  • a safety cabinet which is designed in the present and not restrictive as a battery cabinet and for storing only in the Fig. 1 indicated batteries.
  • the batteries 1 are on the one hand carried by a shelf 2 and on the other hand are held in a drawer 3.
  • the shelf 2 and the drawer 3 can each be pulled out of a cabinet body 4 with the doors 5 open, in order to take hold of individual batteries 1 located thereon or to put them down for storage.
  • the two doors or cabinet doors 5 are revolving doors or cabinet doors 5 which are rotatably connected to the cabinet body 4.
  • the two swing doors 5 are articulated to a common connecting element 7 via push rods 6. You can see that when you compare the Figures 1 and 3 .
  • the common connecting element 7 for the hinged doors 5 is guided in the interior of the cabinet body 4 with the aid of a rail 8.

  • the spring 9 is stretched.
  • a door locking mechanism 6, 7, 8, 9, 10, 12 is implemented at this point, which consists of the two push rods 6 for the cabinet doors 5, the common connecting element 7, the rail 8 for guiding the connecting element 7, the spring 9 and finally the one or the two electromagnets 10, which in turn are acted upon by the control unit 11.
  • the door locking mechanism 6, 7, 8, 9, 10, 12 within the scope of the exemplary embodiment is also assigned a locking element 12, which is kept in its unlocked position throughout and only assumes its locked position when there is a closing signal to be explained below.

Only when the control unit 11 generates a closing signal is the locking element 12 moved into its locked and exposed position with respect to the cabinet body 4. In the locked or exposed position, the locking element 12 or the locking pin engages in one or both cabinet doors 5 and ensures that these are locked with respect to the cabinet body 4 and cannot be opened.
  • An automatic door closer 7, 8, 9 is also implemented as part of the door closing mechanism 6, 7, 8, 9, 10, 12, which is triggered by the control unit 11 when the previously mentioned closing signal is received.
