Definitions
- the invention relates to a safety cabinet, in particular a fire protection cabinet for receiving hazardous substances, preferably a battery cabinet for receiving and storing high-performance batteries such as lithium-ion batteries, with a cabinet body and at least one swing door connected to the cabinet body, furthermore with at least one locking element on the swing door and / or on the cabinet body, and with at least one fuse, in particular a fuse, wherein the fuse holds the locking element, which is designed as a locking element that is not accessible from the outside, in the unlocked position and only releases it in the event of a fire to assume its locked position.
- a safety cabinet in particular a fire protection cabinet for receiving hazardous substances
- a battery cabinet for receiving and storing high-performance batteries such as lithium-ion batteries
- Safety cabinets and other fire protection cabinets are typically used to hold hazardous substances such as liquid and flammable chemicals. However, gas bottles or solid hazardous substances can also be stored inside, for example.
- the safety cabinets or fire cabinets In order to protect the hazardous substances from possible external sources of fire, the safety cabinets or fire cabinets have a specified fire resistance, which corresponds to different fire resistance periods.
- the fire protection cabinets in question are usually classified according to the regulation DIN EN 14470. A total of four levels of fire resistance duration of 15 minutes, 30 minutes, 60 minutes and finally 90 minutes are distinguished, as exemplified in the utility model DE 20 2014 101 935 U1 the applicant is described.
- the WO 2012/126664 A1 deals with a cabinet and in particular a gas bottle cabinet, in which the two cabinet doors have an espagnolette lock and a tab lock by means of a common rotary latch are simultaneously unlockable / lockable. This allows both locking and unlocking as well as problem-free and quick door opening.
- the spring acts on the locking element in the direction of the locking position. As soon as the swing door goes into the closed position, a mechanical lock releases the locking element, which is acted upon by the spring and transferred into the locked position. To unlock the known swing door, it is only necessary to unlock the locking element with the aid of a handle. This has generally proven itself.
- the outer source of the fire ensures that the fuse operates and the swing door is closed automatically by spring force.
- the swing door in the generic state of the art according to the US 6 250 015 B1 additionally locked.
- the safety cabinet can be unlocked using the outer handle and the swing door opened.
- the safety cabinet in question is preferably a battery cabinet.
- DE 101 14 960 C1 are already role models that provide a heat transfer device for temperature control of the interior of the housing in such a battery cabinet to a predetermined temperature level.
- the interior of the housing is to be kept in a predetermined temperature range even in the event of large temperature fluctuations outside the housing.
- the heat transfer device can be thermally conductively connected to a heat exchanger provided on the outside of the housing, which is structurally complex.
- the invention is based on the technical problem of further developing a safety cabinet of the construction described above and the associated configuration in such a way that sources of fire, in particular in the interior of the cabinet, are controlled.
- the invention proposes in a generic safety cabinet and preferably a battery cabinet for receiving and storing high-performance batteries that two fuses are provided which are arranged in series and are connected to one another by means of a connecting element and to the locking element.
- the locking element is designed as a handle-free door catch.
- the swing door is positively closed in the locked position of the locking element with respect to the cabinet body. As part of this forced closure, the swing door is forced into its closed position. In this positively closed position of the swing door in relation to the cabinet body and in the locked position of the locking element, the swing door can only be opened after an emergency release.
- this locking element is designed as a locking element.
- the locking element cannot be acted on from the outside, that is, from outside the safety cabinet. Consequently, the locking element is designed to be free of handling. This is preferably a door catch and, as a rule, a handling-free door catch.
- the locking element is provided on the inside of the swing door and / or the cabinet body. The procedure is usually that the locking element is connected to an inside of the swing door.
- the fuse or fuse now ensures according to the invention that the locking element in question and designed as a latching element is held in its unlocked position throughout.
- the fuse or fuse only releases the locking element in the event of a fire. This allows the locking element to assume its locked position. This usually happens through the force of a spring. That is to say that the locking element is typically equipped with at least one spring which, after its release by the fuse or fuse, transfers the locking element from the unlocked position previously assumed to the locked position.
- the fuse actually holds the locking element in the unlocked position against the force of the tensioned spring.
- the locked position of the locking element is taken in the event of a fire, regardless of whether the swing door is open or closed at this time.
- the swing door is positively closed in the locked position of the locking element with respect to the cabinet body, provided that it is open in the event of a fire. Since it is Locking element is a latching element and in particular a handling-free door snapper, the previously opened and in the event of fire force-closed swing door can easily occur. Because here the door catch is pushed back against the force of its spring for a short time and then snaps back into the locked position. The swing door is now in its positively closed position opposite the cabinet body and the locking element assumes its locked position.
- the swing door can only be unlocked emergency.
- This emergency release may only be carried out by specially trained personnel, such as the fire brigade.
- one can proceed for the emergency release for example, in such a way that the locking element is transferred from the assumed locked position into the unlocked position by a special emergency release lever or emergency release button. Only then can the swing door be opened (again).
- the emergency release lever or button in question can be attached, for example, to an inaccessible point in the safety cabinet.
- the locking element is designed as a locking pin which, in its locked position, engages in a pin receptacle on an adjacent swing door and / or in the cabinet body.
- the first variant corresponds to the fact that the safety cabinet according to the invention is equipped with two swing doors which are each articulated and pivotably connected to the cabinet body. With the help of the locking element the two swing doors are now locked against each other after their forced closing. Since the locking element is designed as a locking element that is not accessible from the outside or handling-free door snapper, the two swing doors cannot be opened from the outside in their positively closed position and when the locking element is in the locked position. Rather, the previously described emergency release is required for this again.
- the locking element is equipped with at least one spring.
- the locking pin can be moved against the force of the spring from the locked and exposed position to the unlocked and retracted position.
- the safety fuse holds the locking element or the locking pin in the relevant unlocked position against the force of the spring under tension.
- two fuses and in particular two fuses are provided. These two fuses can be designed, for example, as internal and external security.
- the interior fuse may be arranged in the interior of the cabinet, while an exterior fuse is placed on an outer surface of the cabinet body.
- possible sources of fire in the interior of the cabinet can be detected with the aid of the internal security, while the external security typically reacts to sources of fire outside the security cabinet.
- the respective fuse or fuse is triggered and breaks in the event of a fire.
- the fuse or fuse is advantageously a fusible link or filament that breaks at temperatures above 50 ° C and in particular at 70 ° C and more.
- the fuse can also be a thermocouple.
- a glass cartridge filled with liquid may be used.
- the liquid is deflagrated and the glass cartridge bursts (also referred to as “backdraft”).
- the fuse can (no longer) hold the locking element in the unlocked position, so that the locking element assumes its locked position. This is ensured by the spring of the locking element.
- a first fuse and a second fuse can be distributed in the interior of the cabinet.
- the invention is based on the knowledge that, in particular when batteries and preferably high-performance batteries such as lithium-ion batteries are stored, locally limited sources of fire can arise inside the relevant safety cabinet. For example, it is conceivable that a battery placed on the bottom catches fire. So that such a locally limited source of fire reliably triggers the fuse and in particular the fuse, the previously described distributed arrangement of the first and the second fuse in the interior of the cabinet is recommended.
- the two fuses are arranged in series and coupled to one another.
- the row arrangement achieves an OR link in the sense that it is sufficient if only one of the two fuses trips in the event of a fire.
- both fuses can also trip.
- the series connection and coupling of the fuses ensures that both in the event of a fire inside the safety cabinet and outside, the locking element previously held in the unlocked position reliably assumes its locked position.
- the connecting element can be a connecting cable. If an internal safety device and an external safety device are implemented, the connecting element or connecting cable in question can be passed through an opening in the cabinet body, in order to couple the external safety device through the opening to the internal safety device in the example.
- a tension spring is usually also provided.
- the fuse or fuse or the two fuses or fuses ensure that the tension spring in question is kept in a tensioned state. If there is a fire, one or both fuses are triggered. The fuse breaks so that the tension spring changes from its tensioned to the relaxed state. Since the locking element or the locking pin is connected to the tension spring, the relaxing tension spring ensures that the locking element or the locking pin changes from the previously taken unlocked to the locked position. in principle the tension spring in question is also dispensable because the locking element in turn has the spring which has already been explained and integrated, as it were.
- the one spring or the two springs ie the spring in the locking element and the tension spring, are tensioned in the unlocked position of the locking element.
- the fuse or fuse breaks (in the event of a fire)
- one spring or the two springs are released.
- the locking element assumes its unlocked position.
- a particularly compact and functional design of the invention is realized in the event that the fuse or fuse not only holds the locking element in the unlocked position, but the fuse may additionally ensure that a protective flap assigned to an opening in the cabinet body is also kept in the open position becomes.
- This protective flap can be a locking slide which is adjusted linearly and thereby closes the opening in question in its closed position.
- the fuse or fusible link can also hold the swing door in the open position.
- an additional spring assigned to the swing door and previously tensioned or the tension spring already mentioned may ensure that the swing door is moved from its open position to the closed position. This is the previously closed position of the swing door with respect to the cabinet body, as previously described. Since the locking element also assumes its locked position during this process, the questionable can The swing door in this function position can no longer be opened from the outside. Rather, the previously described emergency release is required to be able to open the swing door again.
- the fuse or fuse In the event of a fire, the fuse or fuse not only releases the locking element for assuming its locked position. Instead, the protective flap for closing the opening can also be released. As an alternative or in addition, the safety device or fusible device can also release the swing door to assume its closed position. In this way, the safety cabinet according to the invention is able to react both to an internal source of fire and to one which is observed outside and is detected with the aid of the fuse or fuse.
- the breakage of the fuse or fusible link means that any opening in the cabinet body is closed.
- This opening may be a supply air / exhaust air opening.
- the swing door or the two swing doors are positively closed.
- the locking element assigned to the respective swing door and not accessible from the outside and designed as a locking element assumes its locked position. In this locked position, the one swing door or the two swing doors are locked against each other or against the cabinet body, without this locking being released with a handle or otherwise from the outside.
- the swing door in question can usually only be unlocked and then opened by qualified personnel. This is particularly important in that the handling of one that arises in the interior of the cabinet internal fire source may require special knowledge and special precautionary measures.
- the safety cabinet in question is hermetically or almost hermetically sealed when such an internal source of fire occurs because the opening for ventilation is blocked off with the aid of the protective flap or the locking slide and additionally one or the two swing doors are positively closed. In principle, this means that the source of the fire that arises inside is "suffocated".
- the source of the fire in question can still glow. If an unprepared person then opens the swing door, this can lead to a deflagration and a flare up again.
- the invention consequently provides for emergency unlocking, which typically may only be carried out by qualified personnel. The personnel in question has been informed in advance of the contents of the safety cabinet so that appropriate safety measures and precautions can be taken when the emergency release and opening of the swing door are opened.
- the safety cabinet according to the invention is particularly predestined for the storage and storage of high-performance batteries with the specific problems described above. Any danger to the operating personnel is reliably excluded. All of this is possible taking into account a compact and at the same time inexpensive structure. The main advantages can be seen here.
- the safety cabinet can be a fire protection cabinet to hold hazardous substances such as liquid chemicals.
- the design of the safety cabinet in question and to be described in more detail below as a battery cabinet is very particularly preferred.
- the battery cabinet in question functions to hold and store high-performance batteries such as lithium-ion batteries.
- the safety cabinet has a cabinet body 1.
- each two swing doors 2 pivotally connected.
- the two swing doors 2 can be opened and closed, as shown by two double arrows in the Fig. 1 suggest.
- the cabinet in question is still equipped with a fuse 3, 4.
- the fuse 3, 4 is a fuse 3, 4.
- an inner fuse 3 and an outer fuse 4 are implemented in this context.
- the interior fuse 3 takes place itself in the interior of the cabinet or inside the cabinet body 1, while the external fuse 4 is provided on an outer surface of the cabinet body 1. This is shown by a dashed line in the Fig. 1 and 2 indicated.
- the respective fuse 3, 4 is designed as a fuse or fusible link. As soon as a temperature or melting temperature of 50 C and in particular 70 C and more is reached in the cabinet interior or outside the cabinet, this melting temperature leads to the fuse or fuse 3, 4 in question breaking.
- the two fuses 3, 4 are arranged in series and coupled together.
- a connecting element 5 is provided.
- the connecting element 5 is a connecting cable.
- the connecting element or connecting cable 5 can be passed through an opening 6 in the cabinet body 1 for coupling the external fuse 4 to the internal fuse 3, as shown in FIG Fig. 2 shown and in the Fig. 1 is indicated.
- a tension spring 7 is also realized.
- the tension spring 7 connects the two fuses 3, 4 and two locking elements 8 to one another. This is ensured by the connecting element or the connecting cable 5.
- two locking elements 8 are provided on the associated swing door 2.
- Each swing door 2 has an associated locking element 8.
- the locking element 8 is connected to an inside of the respective swing door 2.
- the respective locking element 8 is designed as a locking element that is inaccessible from the outside.
- the locking element 8 is in each case a handling-free one Door catch 8, as shown in the detail sections in the illustration according to the 3A and 3B becomes clear.
- the Fig. 3 shows, in contrast, the locked position of the door catch 8.
- the unlocked position of the locking element or door catch 8 is in each of the Fig. 1 and 2 shown in the drawing.
- the transition from the unlocked position of the relevant door catch 8 into its locked position is in the Fig. 1 indicated by corresponding arrows.
- the fuse or fuse 3, 4 now ensures that the respective locking element or the respective door catch 8 in its in the Figure 3A Unlocked position shown is held. In addition, the fuse or fuse 3, 4 releases the locking element 8 in question only in the event of a fire. Because in the event of a fire, the locking element or the door catch 8 takes its place in the Figure 3B locked position shown a. This corresponds to a movement of the door catch 8 in the direction of the respective arrows in FIG Fig. 1 ,
- the fuse 3, 4 or fuse keeps the tension spring 7 in question in the tensioned state. As soon as one of the two fuses 3, 4 breaks, the tension spring 7 can relax. As a result, the respective locking element 8 changes from the unlocked position to the locked position. This is additionally ensured by a spring 9.
- the locking element 8 is in each case equipped with at least one spring 9. The spring 9 (in connection with the tension spring 7) ensures that the locking element 8 passes into the exposed and locked position when there is no tension on the connection element 5 and consequently when the fuse 3, 4 is broken (cf. Figure 3B ).
- the swing door 2 in question can no longer be opened.
- the locking element or the door catch 8 is designed to be unmanageable, so it cannot be unlocked, for example, by a handle that can be actuated from the outside.
- the two swing doors 2 may each be equipped with a pressure snap as a handle, as in the utility model DE 20 2012 102 233 U1 the applicant is described in this context.
- an espagnolette lock with handle is of course similar to that WO 2012/126664 A1 conceivable.
- the respective swing door 2 must be unlocked in this state. Only specially qualified personnel are able to do this for security reasons. This is because the described fire and the triggering of one or the two fuses 3, 4 can lead to injuries to the operator and / or deflagration and / or flare-up if the swing door 2 opens uncontrolled, which is expressly prevented according to the invention. This is because the need for emergency unlocking inevitably requires awareness and special security and precautionary measures.
- the locking element 8 in question is nevertheless transferred to its locked position. Subsequently or simultaneously, the swing door 2 is brought into its positively closed position with respect to the cabinet body 1. This can be done via one or the two fuses 3, 4.
- Fig. 2 be proceeded so that with the help of one or the two fuses 3, 4, a carrier element 10 of the two swing doors 2 from its in the Fig. 2 shown solid and open position in a likewise in the Fig. 2 shown dashed closed position is transferred.
- this transition does not take place with the aid of the two fuses 3, 4, but with the use of an additional and further fusible link 18.
- the swing door 2 located in the positively closed position in relation to the cabinet body 1 and with the locking element 8 located in the locked position can only be opened after the emergency release.
- This emergency release is usually flanked by additional security measures, so that a flare-up of the source of the fire in the interior of the cabinet as well as injuries to the operator are avoided.
- the locking element 8 is designed as a locking pin 8 which, in its locked position, corresponds to the illustration in FIG Figure 3B engages in an associated pin receptacle 11.
- the pin receptacle 11 in question can be formed in the adjacent swing door 2.
- the pin receptacle 11 is formed in the cabinet body 1 if the locking element 8 is attached to an edge of the swing door 2 on the cabinet side.
- the interpretation is such that the relevant locking element 8 is placed on a door-side edge of the associated swing door 2.
- the fuse or fuse 3, 4 not only holds the locking element or the locking pin 8 in the unlocked position, namely against the force of the spring 9, which is consequently tensioned in this unlocked position. Instead, the fuse 3, 4 additionally ensures that a protective flap 12 does not cover an opening 13, 14 in the cabinet body 1 in its open position.
- the two openings 13, 14 are, on the one hand, a supply air opening 13 and, on the other hand, an exhaust air opening 14.
- the fuse 3, 4 can ensure that the swing door 2 in question remains in the open position, but this is not shown. Rather, this is ensured by the additional fuse 18.
- the fusible link 3, 4 in question not only releases the locking element or the respective locking pin 8 to assume its locked position, as shown by two arrows in FIG Fig. 1 suggest. Instead, in this case, the protective flap 12 assigned to the two openings 13, 14 is additionally and additionally acted upon to assume the closed position. Because triggering the concerned Fusible link 3, 4 causes the tension spring 7 to relax and consequently the protective flap 12 acted upon by it can no longer hold back. Consequently, the protective flap 12 follows the tension spring 7 and closes the two openings 13, 14.
- the protective flap 12 in the exemplary embodiment is a non-restrictive locking slide.
- the fuse 18 ensures in the event of a fire that the respectively opened swing door 2 or the two opened swing doors 2 assume their closed position. Because when the fuse 18 is triggered, the associated spring 19, which is only indicated and is assigned to the two swing doors 2, is relaxed. As a result, the spring 19 takes the carrier element 10 coupling the two swing doors 2 along along a guide 15, so that the respectively opened swing door 2 is positively closed.
- the temperature sensor 16 may be provided in the interior of the cabinet or in the interior of the cabinet body 1. According to the Fig. 1 the temperature sensor 16 is connected to a control unit 17 or a network (not shown in more detail). As a result, the temperatures in the interior of the cabinet detected by the temperature sensor 16 can be transmitted to a remote control center. A message is generated in this control center depending on the temperatures detected by the temperature sensor 16 and consequently depending on a fire in the interior of the cabinet. At the same time, this message can be interpreted and implemented in such a way that the emergency unlocking of the safety locker described above becomes necessary.
Description
Die Erfindung betrifft einen Sicherheitsschrank, insbesondere Brandschutzschrank zur Aufnahme von Gefahrstoffen, vorzugsweise einen Batterieschrank zur Aufnahme und Lagerung von Hochleistungsbatterien wie Lithium-Ionen-Batterien, mit einem Schrankkorpus sowie zumindest einer an den Schranckorpus angeschlossenen Drehflügeltür, ferner mit wenigstens einem Verriegelungselement an der Drehflügeltür und/oder am Schrankkorpus, und mit zumindest einer Sicherung, insbesondere Schmelzsicherung, wobei die Sicherung das als von außen nicht zugängliches Rastelement ausgebildete Verriegelungselement in entriegelter Position hält und lediglich im Brandfall zur Einnahme seiner verriegelten Position freigibt.The invention relates to a safety cabinet, in particular a fire protection cabinet for receiving hazardous substances, preferably a battery cabinet for receiving and storing high-performance batteries such as lithium-ion batteries, with a cabinet body and at least one swing door connected to the cabinet body, furthermore with at least one locking element on the swing door and / or on the cabinet body, and with at least one fuse, in particular a fuse, wherein the fuse holds the locking element, which is designed as a locking element that is not accessible from the outside, in the unlocked position and only releases it in the event of a fire to assume its locked position.
Sicherheitsschränke und andere Brandschutzschränke dienen typischerweise zur Aufnahme von Gefahrstoffen wie flüssigen und brennbaren Chemikalien. Es können aber auch beispielsweise Gasflaschen oder feste Gefahrstoffe im Innern bevorratet werden. Um die Gefahrstoffe vor etwaigen äußeren Brandherden zu schützen, verfügen die Sicherheitsschränke bzw. Brandschutzschränke über eine vorgegebene Feuerwiderstandsfähigkeit, die zu unterschiedlichen Feuerwiderstandsdauern korrespondiert. Tatsächlich werden die fraglichen Brandschutzschränke üblicherweise entsprechend der Vorschrift DIN EN 14470 klassifiziert. Insgesamt werden hierbei vier Stufen an Feuerwiderstandsdauer von 15 min, 30 min, 60 min und schließlich 90 min unterschieden, wie dies beispielhaft im Gebrauchsmuster

Die Feder beaufschlagt das Verriegelungselement in Richtung der Verriegelungsposition. Sobald die Drehflügeltür in die geschlossene Stellung übergeht, gibt eine mechanische Sperre das Verriegelungselement frei, welches beaufschlagt von der Feder in die verriegelte Position überführt wird. Zur Entriegelung der bekannten Drehflügeltür ist es lediglich erforderlich, mit Hilfe einer Handhabe das Verriegelungselement zu entriegeln. Das hat sich grundsätzlich bewährt.The spring acts on the locking element in the direction of the locking position. As soon as the swing door goes into the closed position, a mechanical lock releases the locking element, which is acted upon by the spring and transferred into the locked position. To unlock the known swing door, it is only necessary to unlock the locking element with the aid of a handle. This has generally proven itself.

Im Stand der Technik werden praktisch ausschließlich Situationen betrachtet, bei denen die Gefahr besteht, dass ein außerhalb des Sicherheitsschrankes entstehender Brandherd die Gefahrstoffe im Innern erfasst. Um dies zu verhindern, wird der fragliche Sicherheitsschrank im Regelfall verschlossen.In the prior art, situations are considered practically exclusively in which there is a risk that a source of fire outside the safety cabinet will detect the hazardous substances inside. In order to prevent this, the security cabinet in question is usually locked.
Tatsächlich sorgt der äußere Brandherd dafür, dass die Schmelzsicherung anspricht und die Drehflügeltür automatisch per Federkraft geschlossen wird. Bei diesem Vorgang wird die Drehflügeltür im gattungsbildenden Stand der Technik nach der
In neuerer Zeit werden Sicherheitsschränke zunehmend auch zur Lagerung von Batterien und insbesondere Hochleistungsbatterien wie Lithium-Ionen-Batterien eingesetzt. Das heißt, bei dem betreffenden Sicherheitsschrank handelt es sich bevorzugt um einen Batterieschrank. Hier gibt es im Stand der Technik entsprechend der
Die Handhabung von Batterien und insbesondere Hochleistungsbatterien wie Lithium-Ionen-Batterien ist nicht unproblematisch. Das lässt sich im Kern darauf zurückführen, dass solche Batterien beim Ladevorgang und selbst bei der Lagerung einen Kurzschluss in einer oder mehreren Batteriezellen aufweisen können. Tatsächlich werden typischerweise mehrere Lithium-Ionen-Batteriezellen zu einem Batteriemodul verschaltet.The handling of batteries and especially high-performance batteries such as lithium-ion batteries is not without problems. In essence, this can be attributed to the fact that such batteries can have a short circuit in one or more battery cells during charging and even during storage. In fact, several lithium-ion battery cells are typically connected to form a battery module.
Das sogenannte Überladeverhalten solcher Lithium-Ionen-Batteriezellen bzw. der fertig verschalteten Lithium-Ionen-Batterie oder auch des Batteriemoduls hat sich in der Praxis als kritisch erwiesen. Denn ein Aufladevorgang über die maximal zulässige Spannung hinaus kann eine Schädigung der Batteriezelle bis zu einem sogenannten "Durchgehen" der Batteriezellen hervorrufen. Als Folge hiervon kann eine Explosion der Batteriezelle eintreten. Durch diesen Kurzschluss kann es je nach Spannungsniveau außerdem zu einem Lichtbogen und folglich Brand kommen. Das ist selbst bei aufgeladenen Lithium-Ionen-Batterien im Lagerungszustand und ohne zusätzlichen Ladevorgang möglich.The so-called overcharging behavior of such lithium-ion battery cells or the fully connected lithium-ion battery or the battery module has proven to be critical in practice. Because a charging process beyond the maximum permissible voltage can damage the battery cell up to a so-called "runaway" of the battery cells. As a result, the battery cell may explode. Depending on the voltage level, this short circuit can also lead to an arc and consequently fire. This is possible even with charged lithium-ion batteries in the stored state and without an additional charging process.

Aus diesem Grund hat man im Stand der Technik beispielsweise nach der
Der Erfindung liegt das technische Problem zugrunde, einen Sicherheitsschrank des eingangs beschriebenen Aufbaues und der zugehörigen Ausprägung so weiter zu entwickeln, dass insbesondere im Schrankinnenraum entstehende Brandherde beherrscht werden.The invention is based on the technical problem of further developing a safety cabinet of the construction described above and the associated configuration in such a way that sources of fire, in particular in the interior of the cabinet, are controlled.
Zur Lösung dieser technischen Problemstellung schlägt die Erfindung bei einem gattungsgemäßen Sicherheitsschrank und vorzugsweise Batterieschrank zur Aufnahme und Lagerung von Hochleistungsbatterien vor, dass zwei Sicherungen vorgesehen sind, die in Reihe angeordnet und miteinander mittels eines Verbindungselementes und mit dem Verriegelungselement verbunden sind.To solve this technical problem, the invention proposes in a generic safety cabinet and preferably a battery cabinet for receiving and storing high-performance batteries that two fuses are provided which are arranged in series and are connected to one another by means of a connecting element and to the locking element.
Nach vorteilhafter Ausgestaltung ist das Verriegelungselement als handhabungsfreier Türschnapper ausgebildet.According to an advantageous embodiment, the locking element is designed as a handle-free door catch.
Außerdem ist vorgesehen, dass die Drehflügeltür in verriegelter Position des Verriegelungselementes gegenüber dem Schrankkorpus zwangsgeschlossen wird. Im Rahmen dieser Zwangsschließung wird die Drehflügeltür zwangsweise in ihre Schließstellung überführt. In dieser zwangsgeschlossenen Stellung der Drehflügeltür gegenüber dem Schrankkorpus sowie in verriegelter Position des Verriegelungselementes kann die Drehflügeltür lediglich nach einer Notentriegelung geöffnet werden.It is also provided that the swing door is positively closed in the locked position of the locking element with respect to the cabinet body. As part of this forced closure, the swing door is forced into its closed position. In this positively closed position of the swing door in relation to the cabinet body and in the locked position of the locking element, the swing door can only be opened after an emergency release.
Im Rahmen der Erfindung kommt also zunächst einmal ein spezielles Verriegelungselement zum Einsatz. Tatsächlich ist dieses Verriegelungselement als Rastelement ausgebildet. Das Rastelement lässt sich von außen, das heißt, von außerhalb des Sicherheitsschrankes, nicht beaufschlagen. Folgerichtig ist das Verriegelungselement handhabungsfrei ausgebildet. Vorzugsweise handelt es sich hierbei um einen Türschnapper und im Regelfall um einen handhabungsfreien Türschnapper. Außerdem ist das Verriegelungselement innenseitig der Drehflügeltür und/oder des Schrankkorpus vorgesehen. Meistens wird so vorgegangen, dass das Verriegelungselement an eine Innenseite der Drehflügeltür angeschlossen ist.In the context of the invention, therefore, a special locking element is used first of all. In fact, this locking element is designed as a locking element. The locking element cannot be acted on from the outside, that is, from outside the safety cabinet. Consequently, the locking element is designed to be free of handling. This is preferably a door catch and, as a rule, a handling-free door catch. In addition, the locking element is provided on the inside of the swing door and / or the cabinet body. The procedure is usually that the locking element is connected to an inside of the swing door.
Auf diese Weise ist sichergestellt, dass das fragliche Verriegelungselement bzw. Rastelement nach Einnahme seiner verriegelten Position von außen nicht in die entriegelte Position überführt werden kann. Befindet sich folglich das Verriegelungselement in der besagten verriegelten Position, so kann die (geschlossene) Drehflügeltür nicht (mehr) geöffnet werden. Auch eine etwaige Handhabe, die beispielsweise mit einer Treibstangenverriegelung ähnlich der Lehre nach der
Die Sicherung bzw. Schmelzsicherung sorgt nun erfindungsgemäß dafür, dass das fragliche und als Rastelement ausgebildete Verriegelungselement durchweg in seiner entriegelten Position gehalten wird. Nur und ausschließlich im Brandfall gibt die Sicherung bzw. Schmelzsicherung das Verriegelungselement frei. Dadurch kann das Verriegelungselement seine verriegelte Position einnehmen. Das geschieht meistens durch die Kraft einer Feder. Das heißt, das Verriegelungselement ist typischerweise mit wenigstens einer Feder ausgerüstet, welche das Verriegelungselement nach seiner Freigabe durch die Sicherung bzw. Schmelzsicherung von der zuvor eingenommenen entriegelten in die verriegelte Position überführt. Tatsächlich hält die Schmelzsicherung das Verriegelungselement in entriegelter Position gegen die Kraft der gespannten Feder.The fuse or fuse now ensures according to the invention that the locking element in question and designed as a latching element is held in its unlocked position throughout. The fuse or fuse only releases the locking element in the event of a fire. This allows the locking element to assume its locked position. This usually happens through the force of a spring. That is to say that the locking element is typically equipped with at least one spring which, after its release by the fuse or fuse, transfers the locking element from the unlocked position previously assumed to the locked position. The fuse actually holds the locking element in the unlocked position against the force of the tensioned spring.
Die Einnahme der verriegelten Position des Verriegelungselementes im Brandfall erfolgt unabhängig davon, ob zu diesem Zeitpunkt die Drehflügeltür geöffnet oder geschlossen ist. Tatsächlich wird die Drehflügeltür in verriegelter Position des Verriegelungselementes gegenüber dem Schrankkorpus zwangsgeschlossen, sofern sie im Brandfall geöffnet ist. Da es sich bei dem Verriegelungselement um ein Rastelement und insbesondere einen handhabungsfreien Türschnapper handelt, kann die zuvor geöffnete und im Brandfall zwangsgeschlossene Drehflügeltür problemlos einfallen. Denn hierbei wird der Türschnapper gegen die Kraft seiner Feder kurzfristig zurückgeschoben und schnappt dann wieder in die verriegelte Position ein. Jetzt befindet sich die Drehflügeltür in ihrer zwangsgeschlossenen Stellung gegenüber dem Schrankkorpus und nimmt das Verriegelungselement seine verriegelte Position ein.The locked position of the locking element is taken in the event of a fire, regardless of whether the swing door is open or closed at this time. In fact, the swing door is positively closed in the locked position of the locking element with respect to the cabinet body, provided that it is open in the event of a fire. Since it is Locking element is a latching element and in particular a handling-free door snapper, the previously opened and in the event of fire force-closed swing door can easily occur. Because here the door catch is pushed back against the force of its spring for a short time and then snaps back into the locked position. The swing door is now in its positively closed position opposite the cabinet body and the locking element assumes its locked position.
In dieser Funktionsstellung kann die Drehflügeltür lediglich notentriegelt werden. Diese Notentriegelung mag nur von speziell geschultem Personal, beispielsweise der Feuerwehr, vorgenommen werden. Tatsächlich kann für die Notentriegelung beispielsweise so vorgegangen werden, dass das Verriegelungselement durch einen speziellen Notentriegelungshebel oder Notentriegelungsknopf von der eingenommenen verriegelten Position in die entriegelte Stellung überführt wird. Erst dann lässt sich die Drehflügeltür (wieder) öffnen. Der fragliche Notentriegelungshebel oder Notentriegelungsknopf kann beispielsweise an einer unzugänglichen Stelle des Sicherheitsschrankes angebracht sein. Es ist aber auch möglich, dass lediglich das zuvor angesprochene geschulte Personal über den Notentriegelungshebel bzw. Notentriegelungsknopf verfügt und diesen zur Bedienung des Verriegelungselementes am Schrankkorpus ansetzt.In this function position, the swing door can only be unlocked emergency. This emergency release may only be carried out by specially trained personnel, such as the fire brigade. In fact, one can proceed for the emergency release, for example, in such a way that the locking element is transferred from the assumed locked position into the unlocked position by a special emergency release lever or emergency release button. Only then can the swing door be opened (again). The emergency release lever or button in question can be attached, for example, to an inaccessible point in the safety cabinet. However, it is also possible for only the previously mentioned trained personnel to have the emergency release lever or emergency release button and use it to operate the locking element on the cabinet body.
Im Allgemeinen ist das Verriegelungselement als Verriegelungszapfen ausgebildet, welcher in seiner verriegelten Position in eine Zapfenaufnahme an einer benachbarten Drehflügeltür und/oder im Schrankkorpus eingreift. Die erste Variante korrespondiert dazu, dass der erfindungsgemäße Sicherheitsschrank mit zwei Drehflügeltüren ausgerüstet ist, die jeweils gelenkig und schwenkbar an den Schrankkorpus angeschlossen sind. Mit Hilfe des Verriegelungselementes werden nun die beiden Drehflügeltüren nach ihrer Zwangsschließung gegeneinander verriegelt. Da das Verriegelungselement als von außen her nicht zugängliches Rastelement bzw. handhabungsfreier Türschnapper ausgebildet ist, können die beiden Drehflügeltüren in ihrer zwangsgeschlossenen Stellung und bei in verriegelter Position befindlichem Verriegelungselement von außen her nicht (mehr) geöffnet werden. Vielmehr ist hierzu erneut zunächst die zuvor beschriebene Notentriegelung erforderlich.In general, the locking element is designed as a locking pin which, in its locked position, engages in a pin receptacle on an adjacent swing door and / or in the cabinet body. The first variant corresponds to the fact that the safety cabinet according to the invention is equipped with two swing doors which are each articulated and pivotably connected to the cabinet body. With the help of the locking element the two swing doors are now locked against each other after their forced closing. Since the locking element is designed as a locking element that is not accessible from the outside or handling-free door snapper, the two swing doors cannot be opened from the outside in their positively closed position and when the locking element is in the locked position. Rather, the previously described emergency release is required for this again.
Wie bereits erläutert, ist das Verriegelungselement mit wenigstens einer Feder ausgerüstet. Der Verriegelungszapfen kann gegen die Kraft der Feder von der verriegelten und exponierten Position in die entriegelte und eingezogene Stellung überführt werden. Die Schmelzsicherung hält das Verriegelungselement bzw. den Verriegelungszapfen in der betreffenden entriegelten Position gegen die Kraft der hierbei gespannten Feder.As already explained, the locking element is equipped with at least one spring. The locking pin can be moved against the force of the spring from the locked and exposed position to the unlocked and retracted position. The safety fuse holds the locking element or the locking pin in the relevant unlocked position against the force of the spring under tension.
Im Rahmen der Erfindung sind zwei Sicherungen und insbesondere zwei Schmelzsicherungen vorgesehen. Diese beiden Sicherungen können beispielsweise als Innensicherung und Außensicherung ausgelegt sein. Die Innensicherung mag dabei im Schrankinnenraum angeordnet werden, während eine Außensicherung eine Platzierung an einer Außenoberfläche des Schrankkorpus erfährt. Auf diese Weise lassen sich mit Hilfe der Innensicherung etwaige Brandherde im Schrankinnenraum erfassen, während die Außensicherung typischerweise auf Brandherde außerhalb des Sicherheitsschrankes reagiert. In beiden Fällen wird die jeweilige Sicherung bzw. Schmelzsicherung im Brandfall ausgelöst und bricht.In the context of the invention, two fuses and in particular two fuses are provided. These two fuses can be designed, for example, as internal and external security. The interior fuse may be arranged in the interior of the cabinet, while an exterior fuse is placed on an outer surface of the cabinet body. In this way, possible sources of fire in the interior of the cabinet can be detected with the aid of the internal security, while the external security typically reacts to sources of fire outside the security cabinet. In both cases, the respective fuse or fuse is triggered and breaks in the event of a fire.
Tatsächlich handelt es sich bei der Sicherung bzw. Schmelzsicherung vorteilhaft um ein Schmelzlot oder einen Schmelzfaden, welcher bei Temperaturen oberhalb von 50°C und insbesondere bei 70°C und mehr bricht.In fact, the fuse or fuse is advantageously a fusible link or filament that breaks at temperatures above 50 ° C and in particular at 70 ° C and more.
Alternativ oder zusätzlich kann es sich bei der Schmelzsicherung auch um ein Thermoelement handeln. Hierbei mag eine mit Flüssigkeit gefüllte Glaspatrone zum Einsatz kommen. Bei einer vorgegebenen Schmelztemperatur, beispielsweise einer Temperatur oberhalb von 50°C und insbesondere bei 70°C und mehr, kommt es hierbei zur Verpuffung der Flüssigkeit und damit zum Bersten der Glaspatrone (auch als "backdraft") bezeichnet. Als Folge hiervon kann die Sicherung das Verriegelungselement (nicht) mehr in der entriegelten Position halten, so dass das Verriegelungselement seine verriegelte Position einnimmt. Hierfür sorgt die Feder des Verriegelungselementes.Alternatively or additionally, the fuse can also be a thermocouple. Here, a glass cartridge filled with liquid may be used. At a predetermined melting temperature, for example a temperature above 50 ° C. and in particular at 70 ° C. and more, the liquid is deflagrated and the glass cartridge bursts (also referred to as “backdraft”). As a result, the fuse can (no longer) hold the locking element in the unlocked position, so that the locking element assumes its locked position. This is ensured by the spring of the locking element.
Alternativ zur Realisierung einer Innensicherung und einer Außensicherung oder auch zusätzlich hierzu ist es möglich, dass eine erste Sicherung und eine zweite Sicherung jeweils verteilt im Schrankinnenraum angeordnet sind. Hierbei geht die Erfindung von der Erkenntnis aus, dass insbesondere bei einer Bevorratung von Batterien und vorzugsweise Hochleistungsbatterien wie Lithium-Ionen-Batterien im Innern des betreffenden Sicherheitsschrankes lokal begrenzte Brandherde entstehen können. Beispielsweise ist es denkbar, dass eine bodenseitig platzierte Batterie Feuer fängt. Damit auch ein solcher lokal begrenzter Brandherd die Sicherung und insbesondere Schmelzsicherung zuverlässig auslöst, empfiehlt sich die zuvor bereits beschriebene verteilte Anordnung der ersten und der zweiten Sicherung im Schrankinnenraum.As an alternative to realizing an internal fuse and an external fuse, or in addition to this, it is also possible for a first fuse and a second fuse to be distributed in the interior of the cabinet. The invention is based on the knowledge that, in particular when batteries and preferably high-performance batteries such as lithium-ion batteries are stored, locally limited sources of fire can arise inside the relevant safety cabinet. For example, it is conceivable that a battery placed on the bottom catches fire. So that such a locally limited source of fire reliably triggers the fuse and in particular the fuse, the previously described distributed arrangement of the first and the second fuse in the interior of the cabinet is recommended.
Hierbei kann beispielsweise so vorgegangen werden, dass eine Sicherung dachseitig im Schrankinnenraum vorgesehen ist, während die andere Sicherung boden- oder fußseitig des Schrankinnenraumes eine Platzierung erfährt. Selbstverständlich können auch noch mehr Sicherungen zum Einsatz kommen. Außerdem lassen sich die eine bzw. die beiden Sicherungen im Schrankinnenraum selbstverständlich mit einer zusätzlichen Außensicherung an der Außenoberfläche des Schrankkorpus kombinieren.This can be done, for example, in such a way that one fuse is provided on the roof side in the cabinet interior, while the other fuse is placed on the floor or foot side of the cabinet interior. Of course, even more fuses can be used. In addition, one or the two fuses in the interior of the cabinet can of course be combined with an additional external fuse on the outer surface of the cabinet body.
In diesen sämtlichen Fällen sind die beiden Sicherungen in Reihe angeordnet und miteinander gekoppelt. Durch die Reihenanordnung wird eine ODER-Verknüpfung in dem Sinne erreicht, dass es ausreicht, wenn lediglich eine der beiden Sicherungen im Brandfall auslöst. Selbstverständlich können auch beide Sicherungen auslösen. Jedenfalls stellt die Reihenschaltung und Kopplung der Sicherungen miteinander sicher, dass sowohl bei einem auftretenden Brandherd im Innern des Sicherheitsschrankes als auch außerhalb das zuvor in entriegelter Position gehaltene Verriegelungselement zuverlässig seine verriegelte Position einnimmt.In all of these cases, the two fuses are arranged in series and coupled to one another. The row arrangement achieves an OR link in the sense that it is sufficient if only one of the two fuses trips in the event of a fire. Of course, both fuses can also trip. In any case, the series connection and coupling of the fuses ensures that both in the event of a fire inside the safety cabinet and outside, the locking element previously held in the unlocked position reliably assumes its locked position.
Zu Verbindung und Kopplung der beiden Sicherungen greift die Erfindung auf ein Verbindungselement zurück. Bei dem Verbindungselement kann es sich um ein Verbindungsseil handeln. Sind eine Innensicherung und eine Außensicherung realisiert, so lässt sich das fragliche Verbindungselement bzw. Verbindungsseil durch eine Öffnung im Schrankkorpus hindurchführen, um im Beispielfall die Außensicherung durch die Öffnung hindurch mit der Innensicherung zu koppeln.To connect and couple the two fuses, the invention uses a connecting element. The connecting element can be a connecting cable. If an internal safety device and an external safety device are implemented, the connecting element or connecting cable in question can be passed through an opening in the cabinet body, in order to couple the external safety device through the opening to the internal safety device in the example.
Zusätzlich ist meistens noch eine Zugfeder vorgesehen. Die Sicherung bzw. Schmelzsicherung bzw. die beiden Sicherungen respektive Schmelzsicherungen sorgen dafür, dass die betreffende Zugfeder in gespanntem Zustand gehalten wird. Kommt es nun zum Brandfall, so wird eine oder werden beide Sicherungen ausgelöst. Die Sicherung bricht, so dass die Zugfeder von ihrem gespannten in den entspannten Zustand übergeht. Da das Verriegelungselement bzw. der Verriegelungszapfen an die Zugfeder angeschlossen ist, sorgt die sich entspannende Zugfeder dafür, dass das Verriegelungselement bzw. der Verriegelungszapfen von der zuvor eingenommenen entriegelten in die verriegelte Position übergeht. Grundsätzlich ist die fragliche Zugfeder aber auch entbehrlich, weil das Verriegelungselement seinerseits über die zuvor bereits erläuterte und gleichsam integrierte Feder verfügt.In addition, a tension spring is usually also provided. The fuse or fuse or the two fuses or fuses ensure that the tension spring in question is kept in a tensioned state. If there is a fire, one or both fuses are triggered. The fuse breaks so that the tension spring changes from its tensioned to the relaxed state. Since the locking element or the locking pin is connected to the tension spring, the relaxing tension spring ensures that the locking element or the locking pin changes from the previously taken unlocked to the locked position. in principle the tension spring in question is also dispensable because the locking element in turn has the spring which has already been explained and integrated, as it were.
Jedenfalls werden die eine Feder bzw. die beiden Federn, das heißt die Feder im Verriegelungselement und die Zugfeder, in der entriegelten Position des Verriegelungselementes gespannt. Sobald die Sicherung bzw. Schmelzsicherung bricht (im Brandfall), wird die eine Feder bzw. werden die beiden Federn entspannt. Dadurch nimmt das Verriegelungselement seine entriegelte Position ein.In any case, the one spring or the two springs, ie the spring in the locking element and the tension spring, are tensioned in the unlocked position of the locking element. As soon as the fuse or fuse breaks (in the event of a fire), one spring or the two springs are released. As a result, the locking element assumes its unlocked position.
Eine besonders kompakte und funktionsgerechte Auslegung der Erfindung ist für den Fall realisiert, dass die Sicherung bzw. Schmelzsicherung nicht nur das Verriegelungselement in entriegelter Position hält, sondern die Sicherung mag zusätzlich dafür sorgen, dass auch eine einer Öffnung im Schrankkorpus zugeordnete Schutzklappe in geöffneter Position gehalten wird. Bei dieser Schutzklappe kann es sich um einen Verriegelungsschieber handeln, welcher linear verstellt wird und hierbei die fragliche Öffnung in seiner geschlossenen Position verschließt. Zusätzlich oder alternativ zu der fraglichen Schutzklappe bzw. dem Verriegelungsschieber kann die Sicherung respektive Schmelzsicherung auch die Drehflügeltür in Offenstellung halten.A particularly compact and functional design of the invention is realized in the event that the fuse or fuse not only holds the locking element in the unlocked position, but the fuse may additionally ensure that a protective flap assigned to an opening in the cabinet body is also kept in the open position becomes. This protective flap can be a locking slide which is adjusted linearly and thereby closes the opening in question in its closed position. In addition or as an alternative to the protective flap in question or the locking slide, the fuse or fusible link can also hold the swing door in the open position.
Sobald die Sicherung im Brandfall bricht, mag eine der Drehflügeltür zugeordnete und zuvor gespannte zusätzliche Feder oder auch die bereits angesprochene Zugfeder dafür sorgen, dass die Drehflügeltür von ihrer Offenstellung in die Schließstellung überführt wird. Hierbei handelt es sich um die zuvor bereits beschriebene zwangsgeschlossene Stellung der Drehflügeltür gegenüber dem Schrankkorpus. Da bei diesem Vorgang außerdem das Verriegelungselement seine verriegelte Position einnimmt, kann die fragliche Drehflügeltür in dieser Funktionsstellung nicht (mehr) von außen geöffnet werden. Vielmehr ist die zuvor bereits erläuterte Notentriegelung erforderlich, um die Drehflügeltür wieder öffnen zu können.As soon as the fuse breaks in the event of a fire, an additional spring assigned to the swing door and previously tensioned or the tension spring already mentioned may ensure that the swing door is moved from its open position to the closed position. This is the previously closed position of the swing door with respect to the cabinet body, as previously described. Since the locking element also assumes its locked position during this process, the questionable can The swing door in this function position can no longer be opened from the outside. Rather, the previously described emergency release is required to be able to open the swing door again.
Die Sicherung bzw. Schmelzsicherung gibt im Brandfall nicht nur das Verriegelungselement zur Einnahme seiner verriegelten Position frei. Sondern es kann auch die Schutzklappe zum Verschluss der Öffnung freigegeben werden. Alternativ oder zusätzlich kann die Sicherung bzw. Schmelzsicherung auch die Drehflügeltür zur Einnahme ihrer Schließstellung freigeben. Auf diese Weise ist der erfindungsgemäße Sicherheitsschrank in der Lage, sowohl auf einen intern entstehenden Brandherd als auch auf einen solchen reagieren zu können, welcher außerhalb beobachtet und mit Hilfe der Sicherung bzw. Schmelzsicherung detektiert wird.In the event of a fire, the fuse or fuse not only releases the locking element for assuming its locked position. Instead, the protective flap for closing the opening can also be released. As an alternative or in addition, the safety device or fusible device can also release the swing door to assume its closed position. In this way, the safety cabinet according to the invention is able to react both to an internal source of fire and to one which is observed outside and is detected with the aid of the fuse or fuse.
In diesen sämtlichen Fällen führt der Bruch der Sicherung bzw. Schmelzsicherung dazu, dass eine etwaige Öffnung im Schrankkorpus verschlossen wird. Bei dieser Öffnung mag es sich um eine Zuluft/AbluftÖffnung handeln. Zugleich wird die Drehflügeltür bzw. werden die beiden Drehflügeltüren zwangsgeschlossen. Außerdem nimmt das der jeweiligen Drehflügeltür zugeordnete und von außen her nicht zugängliche sowie als Rastelement ausgebildete Verriegelungselement seine verriegelte Position ein. In dieser verriegelten Position ist die eine Drehflügeltür bzw. sind die beiden Drehflügeltüren gegeneinander bzw. gegenüber dem Schrankkorpus verriegelt, und zwar ohne dass diese Verriegelung mit einer Handhabe oder sonst wie von außen aufgehoben werden könnte.In all of these cases, the breakage of the fuse or fusible link means that any opening in the cabinet body is closed. This opening may be a supply air / exhaust air opening. At the same time, the swing door or the two swing doors are positively closed. In addition, the locking element assigned to the respective swing door and not accessible from the outside and designed as a locking element assumes its locked position. In this locked position, the one swing door or the two swing doors are locked against each other or against the cabinet body, without this locking being released with a handle or otherwise from the outside.
Vielmehr lässt sich die fragliche Drehflügeltür üblicherweise nur durch qualifiziertes Personal notentriegeln und dann öffnen. Das ist insofern von besonderer Bedeutung, als die Handhabung eines im Schrankinnenraum entstehenden internen Brandherdes unter Umständen besondere Kenntnis und spezielle Vorsichtsmaßnahmen erfordert.Rather, the swing door in question can usually only be unlocked and then opened by qualified personnel. This is particularly important in that the handling of one that arises in the interior of the cabinet internal fire source may require special knowledge and special precautionary measures.
Zwar wird der fragliche Sicherheitsschrank beim Auftreten eines solchen internen Brandherdes hermetisch oder nahezu hermetisch verschlossen, weil die Öffnung zur Be-/Entlüftung mit Hilfe der Schutzklappe respektive des Verriegelungsschiebers abgesperrt wird und zusätzlich die eine oder die beiden Drehflügeltüren zwangsgeschlossen werden. Hierdurch ist prinzipiell damit zu rechnen, dass der im Innern entstehende Brandherd "erstickt" wird.The safety cabinet in question is hermetically or almost hermetically sealed when such an internal source of fire occurs because the opening for ventilation is blocked off with the aid of the protective flap or the locking slide and additionally one or the two swing doors are positively closed. In principle, this means that the source of the fire that arises inside is "suffocated".
Bei der Lagerung von Hochleistungsbatterien in solchen Sicherheitsschränken kann es jedoch selbst bei hermetisch oder nahezu hermetisch geschlossenem Sicherheitsschrank dazu kommen, dass der fragliche Brandherd noch glimmt. Wenn dann eine unvorbereitete Person die Drehflügeltür öffnet, kann dies zu einer Verpuffung und einem erneuten Aufflammen führen. Folgerichtig sieht die Erfindung die Notentriegelung vor, welche typischerweise nur von qualifiziertem Personal vorgenommen werden darf. Das fragliche Personal ist vorher über den Inhalt des Sicherheitsschrankes informiert worden, so dass bei der Notentriegelung und Öffnung der Drehflügeltür entsprechende Sicherheitsmaßnahmen und Vorkehrungen getroffen werden können.When storing high-performance batteries in such safety cabinets, however, even with a hermetically or almost hermetically closed safety cabinet, the source of the fire in question can still glow. If an unprepared person then opens the swing door, this can lead to a deflagration and a flare up again. The invention consequently provides for emergency unlocking, which typically may only be carried out by qualified personnel. The personnel in question has been informed in advance of the contents of the safety cabinet so that appropriate safety measures and precautions can be taken when the emergency release and opening of the swing door are opened.
Jedenfalls ist der erfindungsgemäße Sicherheitsschrank für die Aufnahme und Bevorratung von Hochleistungsbatterien mit den zuvor geschilderten spezifischen Problemen besonders prädestiniert. Eine etwaige Gefährdung des Bedienpersonals wird zuverlässig ausgeschlossen. Das alles gelingt unter Berücksichtigung eines kompakten und zugleich kostengünstigen Aufbaues. Hierin sind die wesentlichen Vorteile zu sehen.In any case, the safety cabinet according to the invention is particularly predestined for the storage and storage of high-performance batteries with the specific problems described above. Any danger to the operating personnel is reliably excluded. All of this is possible taking into account a compact and at the same time inexpensive structure. The main advantages can be seen here.

In den Figuren ist ein Sicherheitsschrank dargestellt. Bei dem Sicherheitsschrank kann es sich um einen Brandschutzschrank zur Aufnahme von Gefahrstoffen wie beispielsweise flüssigen Chemikalien handeln. Ganz besonders bevorzugt ist die Auslegung des fraglichen und nachfolgend noch näher im Detail zu beschreibenden Sicherheitsschrankes als Batterieschrank. Tatsächlich fungiert der betreffende Batterieschrank zur Aufnahme und Lagerung von Hochleistungsbatterien wie Lithium-Ionen-Batterien.A safety cabinet is shown in the figures. The safety cabinet can be a fire protection cabinet to hold hazardous substances such as liquid chemicals. The design of the safety cabinet in question and to be described in more detail below as a battery cabinet is very particularly preferred. In fact, the battery cabinet in question functions to hold and store high-performance batteries such as lithium-ion batteries.
Zu diesem Zweck verfügt der Sicherheitsschrank über einen Schrankkorpus 1. An den Schrankkorpus 1 sind im Ausführungsbeispiel nach den
Bei der Sicherung 3, 4 handelt es sich im Ausführungsbeispiel um eine Schmelzsicherung 3, 4. Tatsächlich sind in diesem Zusammenhang eine Innensicherung 3 und eine Außensicherung 4 realisiert. Die Innensicherung 3 findet sich im Schrankinnenraum bzw. im Innern des Schrankkorpus 1, während die Außensicherung 4 an einer Außenoberfläche des Schrankkorpus 1 vorgesehen ist. Das wird durch eine jeweils gestrichelte Darstellung in den
Die jeweilige Schmelzsicherung 3, 4 ist als Schmelzfaden oder Schmelzlot ausgebildet. Sobald im Schrankinnenraum oder außerhalb des Schrankes eine Temperatur bzw. Schmelztemperatur von 50 C und insbesondere 70 C und mehr erreicht wird, führt diese Schmelztemperatur dazu, dass die betreffende Sicherung respektive Schmelzsicherung 3, 4 bricht.The
Die beiden Sicherungen 3, 4 sind in Reihe angeordnet und miteinander gekoppelt. Dazu ist ein Verbindungselement 5 vorgesehen. Bei dem Verbindungselement 5 handelt sich um ein Verbindungsseil. Das Verbindungselement bzw. Verbindungsseil 5 kann zur Kopplung der Außensicherung 4 mit der Innensicherung 3 durch eine Öffnung 6 im Schrankkorpus 1 hindurchgeführt werden, wie dies in der
Außerdem ist noch eine Zugfeder 7 realisiert. Die Zugfeder 7 verbindet die beiden Sicherungen 3, 4 und zwei Verriegelungselemente 8 miteinander. Hierfür sorgt das Verbindungselement bzw. das Verbindungsseil 5. Tatsächlich sind beiden Verriegelungselemente 8 an der zugehörigen Drehflügeltür 2 vorgesehen. Dabei verfügt jede Drehflügeltür 2 über ein zugehöriges Verriegelungselement 8. Das Verriegelungselement 8 ist jeweils an eine Innenseite der betreffenden Drehflügeltür 2 angeschlossen.In addition, a
Erfindungsgemäß ist das jeweilige Verriegelungselement 8 als von außen her unzugängliches Rastelement ausgebildet. Tatsächlich handelt es sich im Ausführungsbeispiel bei dem Verriegelungselement 8 jeweils um einen handhabungsfreien Türschnapper 8, wie anhand der Detailausschnitte in der Darstellung nach den
Die Sicherung bzw. Schmelzsicherung 3, 4 sorgt nun dafür, dass das betreffende Verriegelungselement respektive der jeweilige Türschnapper 8 in seiner in der
Um dies im Detail zu erreichen, hält die Sicherung 3, 4 bzw. Schmelzsicherung die fragliche Zugfeder 7 in gespanntem Zustand. Sobald eine der beiden Schmelzsicherungen 3, 4 bricht, kann sich die Zugfeder 7 entspannen. Als Folge hiervon geht das jeweilige Verriegelungselement 8 von der entriegelten Position in die verriegelte Position über. Hierfür sorgt ergänzend eine Feder 9. Tatsächlich ist das Verriegelungselement 8 jeweils mit wenigstens einer Feder 9 ausgerüstet. Die Feder 9 (in Verbindung mit der Zugfeder 7) sorgt dafür, dass das Verriegelungselement 8 bei Wegfall einer Zugbeaufschlagung durch das Verbindungselement 5 und folglich bei gebrochener Schmelzsicherung 3, 4 in die exponierte und verriegelte Position übergeht (vgl.
Sofern die jeweilige Drehflügeltür 2 in der verriegelten Position des Verriegelungselementes 8 ihre geschlossene Stellung gegenüber dem Schranckorpus 1 einnimmt, kann die fragliche Drehflügeltür 2 nun nicht (mehr) geöffnet werden. Denn das Verriegelungselement bzw. der Türschnapper 8 ist handhabungsfrei ausgelegt, lässt sich also nicht beispielsweise durch eine von außen betätigbare Handhabe entriegeln. Beispielsweise mögen die beiden Drehflügeltüren 2 jeweils mit einem Druckschnapper als Handhabe ausgerüstet sein, wie er in dem Gebrauchsmuster
So oder so muss die jeweilige Drehflügeltür 2 in diesem Zustand notentriegelt werden. Hierzu ist lediglich besonders qualifiziertes Personal aus Sicherheitsgründen in der Lage. Denn der beschriebene Brandfall und das Auslösen der einen oder der beiden Schmelzsicherungen 3, 4 kann bei einer unkontrollierten Öffnung der Drehflügeltür 2 zu Verletzungen des Bedieners und/oder einer Verpuffung und/oder einem Aufflammen führen, was erfindungsgemäß ausdrücklich verhindert wird. Denn das Erfordernis der Notentriegelung fordert zwangsweise eine Sensibilisierung und spezielle Sicherungs- und Vorsichtsmaßnahmen.Either way, the
Sofern eine oder beide Drehflügeltüren 2 im geschilderten Brandfall geöffnet sind, wird das betreffende Verriegelungselement 8 dennoch in seine verriegelte Position überführt. Anschließend bzw. gleichzeitig wird die Drehflügeltür 2 in ihre zwangsgeschlossene Stellung gegenüber dem Schrankkorpus 1 verbracht. Das kann über die eine bzw. die beiden Schmelzsicherungen 3, 4 erfolgen.If one or both
Dabei mag ausweislich der
Kommt es zum Bruch dieser Schmelzsicherung 18, so entspannt sich hierbei die Feder 19 und nimmt das fragliche Trägerelement 10 von der durchgezogen dargestellten geöffneten Position (der Drehflügeltüren 2) in die gestrichelt gezeichnete Schließstellung mit. Befindet sich nun das Trägerelement 10 in der gestrichelten Position bzw. Schließstellung gemäß der
Wie bereits erläutert, lässt sich die jeweils in zwangsgeschlossener Stellung befindliche Drehflügeltür 2 gegenüber dem Schrankkorpus 1 sowie bei in verriegelter Position befindlichem Verriegelungselement 8 lediglich nach der Notentriegelung öffnen. Diese Notentriegelung ist meistens mit zusätzlichen Sicherungsmaßnahmen flankiert, so dass ein Wiederaufflammen des Brandherdes im Schrankinnenraum ebenso wie Verletzungen der Bedienpersonen vermieden wird.As already explained, the
Im Detail ist das Verriegelungselement 8 als Verriegelungszapfen 8 ausgebildet, welcher in seiner verriegelten Position entsprechend der Darstellung in der
Anhand der Darstellung in den
Kommt es jedoch zum Brandfall, so gibt die fragliche Schmelzsicherung 3, 4 nicht nur das Verriegelungselement bzw. den jeweiligen Verriegelungszapfen 8 zur Einnahme seiner verriegelten Position frei, wie dies zwei Pfeile in der
Darüber hinaus sorgt die Schmelzsicherung 18 im Brandfall dafür, dass die jeweils geöffnete Drehflügeltür 2 bzw. die beiden geöffneten Drehflügeltüren 2 ihre Schließstellung einnehmen. Denn beim Auslösen der Schmelzsicherung 18 wird die zugehörigen und lediglich angedeutete und den beiden Drehflügeltüren 2 zugeordnete Feder 19 entspannt. Dadurch nimmt die Feder 19 das die beiden Drehflügeltüren 2 koppelnde Trägerelement 10 entlang einer Führung 15 mit, so dass die jeweils geöffnete Drehflügeltür 2 zwangsgeschlossen wird.In addition, the fuse 18 ensures in the event of a fire that the respectively opened
