    Tripping device of an extinguishing system
    The invention relates to a triggering device for a fast-fire extinguishing system for
    Explosion suppression, wherein the triggering device comprises a sliding bolt, wherein the triggering of the extinguishing system is caused by a movement of the sliding bolt from a locking position to a release position and wherein the sliding bolt in the locked position with a detent pressed against a latch edge of a jack body and held by this in the locked position is.
    Furthermore, the invention relates to an extinguishing system for explosion suppression with an extinguishing agent container, which is pressure-tight manner closed by a closure member, wherein the closure member by means of at least one locking element in the closed
    Lockable position.
    In a further aspect, the invention relates to a method for carrying out a
    Test triggering with an extinguishing system.
    In order to suppress explosion, rapidly triggering extinguishing systems are used, in particular powder extinguishers with soda powder and nitrogen having a system pressure of about 60 bar being used. As soon as pressure sensors detect an incipient explosion, a closure system of the extinguisher is opened, whereby due to the required short reaction times, the closure system is generally burst open with explosives. When triggered, it depends on a very high dynamics, with trigger times of less than 10 ms must be achieved.
    The explosives are in many ways a problem, especially the
    Costs, handling, storage, transport, spare part shipping, warehousing, import to different countries, the durability or the verifiability of each constitute their own problem areas.
    Attempting to replace these explosives with mechanical means presents numerous technical hurdles. In particular, with triggering systems of related technical
    Areas such as conventional fire extinguishing systems for the
    Explosion suppression required short tripping times unreachable. EP 1025878 A1 discloses a mechanical release mechanism for a powder extinguisher for explosion suppression, in which the release of a pawl via a rotary actuator with interposed rolling elements. This reduces system friction, which is essential for safe and fast opening. The rotary actuator is driven by a torque motor.
    Further, there is a need for tripping devices for rapid-fire extinguishing systems for explosion suppression, which are simple in construction and inexpensive to manufacture, and which have increased reliability and reduced maintenance. It is an object of the subject invention to provide such systems.
    These and other objects are achieved by a tripping device of the type mentioned, in which the latch body for releasing the engagement of the catch and the latch edge and for releasing the sliding bolt by means of at least one electromagnet is movable. This reduces the number of required moving parts of the triggering device.
    The size, geometry and winding of the electromagnet can be optimized for high dynamics and low energy consumption. It should be noted that the
    Triggering necessary energy must be stored at the extinguishing system, and off
    Safety reasons, certain amounts of energy in the capacitors may not be exceeded.
    Advantageously, the electromagnet can act directly on the jack body, which is the
    System friction minimized.
    In an advantageous embodiment, the latch body may be formed as a one-piece body, whereby the number of moving parts can be minimized.
    Advantageously, the latch body by means of a return spring in the direction of
    Engagement of the catch and latch edge be biased. The return spring serves not only the provision after a test release but also the security against vibrations and shocks and is dimensioned so that sufficient security against self-release exists even with the highest accelerations occurring.
    In a preferred embodiment of the invention, an air gap between the pawl body and the electromagnet may have a wedge-like tapered cross-section. This allows a higher force of the electromagnet on the
    Pawl body, while at the same time allowing for the release of the catch by the pawl movement.
    In a further advantageous embodiment of the invention, the latch body may be pivotally mounted about a pivot point. Due to an optimized arrangement of the
    Pivot point and the distances to the latch flank can be a highly dynamic and reliable triggering enabled. By adjusting the arrangement and shape of the jack body and the angle of the latch edge, the tripping behavior can be further optimized and made independent of the force acting on the sliding bolt.
    In an advantageous embodiment, the pivot point in an area between the
    Be arranged catch and a connecting head of the sliding bolt next to the sliding bolt, the pivot point is preferably vertically spaced apart at a distance of a maximum of 15mm from the bolt axis in particular. Thus, the forces required for triggering and the size can be minimized. The pivot point can be executed as a pivot bearing.
    The pivot point can be arranged in a further advantageous embodiment in an imaginary extension of the sliding bolt in a release direction behind the catch, wherein the pivot point is preferably vertically spaced in particular at a distance of a maximum of 15 mm from the bolt axis.
    The pivot may be formed, for example, by an outer edge of the latch body mounted in an inner edge of a housing. This reduces the one hand
    System friction, on the other hand, the complexity and error rate of the mechanics is minimized.
    Advantageously, the pivot point may be positioned at a distance of between 10mm and 50mm from the electromagnet.
    In a further advantageous embodiment, a pawl sensor may be provided for monitoring the position of the pawl body. This allows to remotely monitor the blocking state of the triggering device.
    The invention further includes an extinguishing system of the type mentioned, which has the tripping device according to the invention, wherein the tripping device acts on the locking element of the extinguishing system.
    In an advantageous manner, the locking element can be blocked by means of an electromechanical actuator in the locking member locking position. Blocking of the locking element is necessary in particular for maintenance purposes when triggering of the extinguishing system must be avoided for safety reasons. With the electromechanical actuator, the lock can directly via a central
    Control system done. The interlocking signal can be sent via a bus cable to the affected extinguishers and locking takes place by means of an electromechanical actuator.
    In an advantageous embodiment, an actuator sensor for monitoring the position of the actuator can be provided. As a result, the reaching of the locking position can be monitored remotely. Only after reaching the locking position is a corresponding signal sent to the control system. Particularly with exposed plant parts, such as high silos, such a monitorable remote locking is a great asset.
    Advantageously, according to the invention, at least the actuator sensor, the latch sensor, the actuator and the electromagnet can be connected to a control system. This makes it possible to perform a fully or partially automatic test triggering centrally controlled, which minimizes the cost of maintenance and inspection of the system.
    According to the invention, a test release can be carried out with the extinguishing system according to a method comprising the following steps: blocking the locking element in the position locking the closure element by means of the actuator, checking the blocking by means of the actuator sensor, releasing the
    Sliding bolt by releasing the jack body by means of the electromagnet, Checking the successful test release by means of the jack sensor, Resetting the jack body, Checking the position of the jack body, releasing the locking element by means of the actuator. These steps can be performed fully automatically by the control system without the need for manual intervention in the extinguishing system.
    The subject invention will be explained in more detail below with reference to Figures 1 to 3, which by way of example, schematically and not restrictive advantageous
    Embodiments of the invention show. It shows
    1 shows an inventive extinguishing system in a sectional view,
    Fig. 2 shows a tripping device according to the invention according to a first embodiment in a sectional view and
    Fig. 3 shows a tripping device according to the invention according to a second embodiment in a sectional view.
    Fig. 1 shows the extinguishing system 11 according to the invention in a cross section. In known manner, an extinguishing agent container 12 is designed with a flap
    Closing member 13 closed. The extinguishing agent container 12 is pressurized and filled with an extinguishing agent. As extinguishing agent, for example, a powder containing soda powder can be used, wherein the extinguishing agent container with nitrogen on a
    System pressure of about 60 bar is brought. The closure member 13 is locked with a lever-like locking element 14. It expresses that
    Locking element 14 with a locking surface 19 against a pressure surface 20 of the
    Closure member 13.
    The dimensions and relative arrangement of the contact plane between locking surface 19 and
    Pressure surface 20, the center of rotation of a pivot bearing 21 of the closure member 13 and the center of rotation of a lever bearing 22 of the locking member 14, and the dimensions of the closure member 13 and the locking member 14 can be optimized to ensure on the one hand a secure pressure-tight locking of the extinguishing agent container 12 by the closure member 13 and on the other hand, when the extinguishing system 11 is triggered, a sufficiently fast unlocking of the
    Locking element 13 and opening the closure member 13 to ensure.
    The lock is released by moving an actuating end 23 of the locking element 14 spaced from the lever bearing 22 in a release direction 24. For this purpose, the locking element 14 is at the operating end 23 with a connecting head 8 of a
    Sliding bolt 2 connected to a triggering device 1, which is described in more detail below. Optionally, the operating end of
    Locking element 14 also act directly on the sliding bolt 2 (without a
    Connecting head 8). The shorter the required movement of the actuating end 23, in order to cause unlocking of the closure member 13, the faster a release of the extinguishing system 11 can take place. On the other hand, the movement is not arbitrarily minimized, since a secure closure of the extinguishing agent container 12 must be ensured.
    So that no additional clamping elements are required, the dimensions and
    Arrangements of closure member 13 and locking element 14 are preferably selected so that the actuating end 23 is biased in the release direction 24 alone due to the system pressure prevailing in the extinguishing agent container 12. The system pressure acts on the closure member 13, which exerts a force on the locking surface 19 of the locking member 14 via the pressure surface 20, which in turn causes a bias in the release direction 24.
    Due to the bias, the actuating end 23 exerts a pressure on the sliding bolt 2 of the triggering device 1 in the release direction 24. The sliding bolt 2 has, at a position spaced from the connecting head 8 in the release direction 24, a detent 3, which is held by a latch flank 4 of a latch body 5 against the biasing force. To trigger the extinguishing system, the catch 3 is released by a movement of the pawl body 5, so that the sliding bolt 2 moves in the release direction 24 in a release position. The on the connection head 8 or directly on the
    Sliding bolt 2 acting biasing force must therefore be sufficiently large to the
    System friction in the triggering device 1 and the sliding bolt 2 highly dynamic (i.e., sufficiently fast for the desired purpose of
    Explosion suppression) to move to the release position.
    Referring now to FIG. 2, an exemplary invention will now be described
    Embodiment of the triggering device 1 described in detail. The latch body 5 has a substantially hook-like shape and is pivotally mounted at a hinge point 7, wherein the pivot point 7 is arranged in the region between the connecting head 8 and the catch 3 above next to the sliding bolt 2. The shape of the
    Pawl body 5, the position of the pivot point 7 and the detent 3 (or the pawl edge 4) are coordinated so that act between latch 3 and latch edge 4 only low frictional forces. This can be achieved in particular by arranging the pivot point 7 close to the pin axis, preferably at a maximum distance of 15 mm from the pin axis.
    The pivot point 7 (or the latch body 5) may preferably be arranged vertically above or below the displacement bolt 2, but also laterally or at a different angle thereto. An arrangement vertically above or below, however, facilitates the consideration of the force acting on the jack body 5 gravity.
    The latch body 5 is additionally held by a return spring 9 in the locked position. The return spring 9 is not only the provision for a test triggering but also the security against vibration and shock and we dimensioned so that there is sufficient security against self-triggering even at the highest occurring accelerations.
    At the side facing away from the sliding bolt 2 of the pawl body 5, an electromagnet 6 is arranged at a small distance from the latch body 5. The pawl body has an anchor material (i.e., a material to which the electromagnetic field excited by the electromagnet 6 exerts an attraction force) so that it can be attracted by the activated electromagnet 6 against the return force of the return spring 9 and moved toward the electromagnet 6. Advantageously, the latch body 5 as a whole consist of the anchor material. The distance between the pawl body 5 and electromagnet 6 forms a thin air gap, which is just large enough to bring the pawl edge 4 out of engagement of the catch 3 when the electromagnet 6 is activated.
    By the pivotal movement of the pawl body 5 about the pivot point 7, the distance between the latch body 5 and electromagnet 6 in the vicinity of the anchor point 7 can be made smaller than in the region of the latch edge 4, where to release the
    Notch 3, the maximum deflection of the pawl body 5 is required. The air gap can thus have a tapering towards the anchor point 7, wedge-like course. As a result, the air gap in the region of the windings of the electromagnet 6, which is closer to the anchor point 7, is very narrow, which maximizes the effect of the electromagnet 6 on the latch body 7.
    The position of the latch body 5 can be electronically monitored via a latch sensor 10.
    The combination of the highly dynamic magnet designed as a solenoid 6 with the advantageous choice of the pivot point 7 and the dimensions of a highly dynamic and reliable release can be made possible. By adapting the
    Dimensions of the pawl body 5 and in particular the angle of the pawl edge 4, the tripping behavior further optimized and acting on the sliding bolt 2
    Preload can be made largely independent.
    In Fig. 3 is a further advantageous embodiment of the invention
    Tripping device 1 shown. The latch body 5 of the embodiment of Fig. 3 is in
    Essentially designed as a simple "plate", wherein the latch edge 4 is arranged on an edge of the latch body 5. One of the pawl edge 4 in the release direction opposite edge of the pawl body 5 forms the pivot point 7, said pivot point 7 is formed by the mounted in an inner edge 25 of a housing 26 outer edge 27 of the pawl body 5. Due to the substantially punctiform storage friction is minimized and there are no additional components required for storage. In particular, forces acting on the pawl body 5 from the sliding bolt 2 are absorbed at the pivot point 7 without appreciable friction moments, whereby the triggering force is hardly influenced by the upcoming preloading force.
    Another advantage of this embodiment is that the air gap between
    Pawl body 5 and electromagnet 6 with respect to that shown in Fig. 2
    Embodiment has been minimized again. The air gap is on one side very low, so that a high power and dynamics can be achieved with the electromagnet.
    The blade body 5 is pressed away from the electromagnet 6 by means of a return spring 9 and into an engagement of the latch flank 4 and catch 3. The return spring 9 may be inserted in a provided in the blade body 5 bore 28, which is a simple
    Assembly allows and minimizes the number of required mounting elements.
    The catch 3 of the sliding bolt 2 may be formed as a ring around the sliding bolt 2 extending surface, so that the sliding bolt 2 may be formed as a rotary body, which is easy to manufacture, and which can be installed in an arbitrarily rotated radial position, which simplifies the assembly. In order to ensure optimum attachment between latch edge 4 and 3 catch can in
    Pawl body 5 may be provided, for example, a groove-shaped recess 29, in which the sliding bolt 2 is fittingly received when he is in the after triggering in
    Release direction 24 moves.
    Thus, the latch body 5 may be formed as a simple, substantially block or block-shaped body in which only the bore 28 and the recess 29 are introduced. If necessary, individual edge surfaces, such as those on the
    Outer edge 27 subsequent short rear surface, be deviating from a cuboid shape.
    Also in this embodiment, the position of the jack body 5 via a
    Latch sensor 10 are electronically monitored.
    A bolt return spring 18 can press the sliding bolt 2 against the release direction 24, so that the locking element 14 is also pressed into a position locking the closure member 13 when, for example, no pressure is built up in the extinguishing agent container 12 before filling.
    Returning to FIG. 1, a further security feature of the extinguishing system 11 according to the invention will be described below.
    Adjacent to the locking element 14, an electromechanically actuable actuator 15 is arranged. For example, the actuator can essentially be embodied as a movable bolt (or a cam) which secures the locking element 14 in the position brought out against the locking element 14 in the position blocking the locking element 13 and secures the locking element 14 in a retracted position unlocking movement allows this and thus "unlocked". The actuator can be electromechanical, with or without gear, driven. Via an actuator sensor 16, the position of the actuator 15 can also be monitored remotely.
    The blocking of the locking element 14 by the actuator 15 can during the
    Transport or when carrying out service work on the containers to be protected.
    Both the actuator (not shown) of the actuator 15, as well as the actuator sensor 16, the
    Pawl sensor 10, the electromagnet 6, and optionally other sensors and
    Actuators may be connected to a central control system 17. As a result, the blocking or securing can take place centrally directly via the control system 17, wherein a plurality of extinguishing systems 11 can be connected in a system to the same control system 17. Preferably via a bus connection control signals can be sent to the affected extinguishers and the sensor signals are received.
    The blocking of the locking element 14 by the actuator 15 can thus from
    Control system 17 are triggered, reaching the blocking position with the
    Actuator sensor is monitored.
    In the blocked position it is possible to ensure the proper functioning of the
    Trigger device by a test trigger to check. In addition to the mobility, the dynamics can be determined via sensors and compared with stored values. This triggering verifiability represents another major difference to the explosive-equipped systems and can provide a much better SIL rating in a risk assessment.
    Automatic test procedures at specific intervals with documentation can be implemented in plants.
