Definitions

  • the invention relates to an extinguishing water barrier with a mechanical locking mechanism.
  • Fire water barriers serve as leakage protection on gates or doors in hazardous goods warehouses.
  • the extinguishing water barriers are lowered and seal the doors and gates near the ground, so that a closed system stands, which extinguishing water,,, holds in the hall. This is especially necessary with contaminated extinguishing water to avoid damage to nature and the environment.
  • the object of the invention is to provide an extinguishing water barrier, which can reliably close the floor-near openings in a hall or a restricted area up to a predetermined height, so that extinguishing water can not run out of the hall or the restricted area and a lesser Susceptible to failure in the event of a fault. Furthermore, the sealing of the barrier sheets without supply of external energy and without human intervention is to be made possible (semi-automatic system).
  • An extinguishing water barrier according to the invention for floor-level openings in halls, rooms or demarcated areas comprises a fastening device for securing the extinguishing water barrier barrier on the floor or on the wall and for holding at least one barrier sheet, wherein the barrier sheet mounted pivotably on the fastening device and on the underside with a Sealing is provided, and a stop which is fastened by means of a second fastening device to the floor or on the wall and against which the pivoted dam barrier strikes, wherein the extinguishing water barrier comprises a locking device attached to the at least one dam blade, wherein the locking device is a biasing unit, a mechanical Locking element and a holding and releasing mechanism comprises, and wherein the mechanical locking element is held by the holding mechanism in an open position, from the biasing unit in a closed Position is urged and the mechanical locking element by the release mechanism from the open position is solvable.
  • the mechanical locking device ensures that the dam barrier is firmly anchored to the ground without additional electrical or pneumatic systems.
  • the susceptibility to failure in case of failure is greatly reduced, since there are only mechanical elements that can not be damaged by the accident, such as electrical malfunction.
  • Floor-level openings designate all entrances and exits, but also windows through which extinguishing water from the hall or the areas delimited by walls can flow into the environment.
  • the solution according to the invention does not use the BGR Rule 232 - Power-operated doors and gates, which allows considerable savings in terms of procurement, production, installation and maintenance.
  • the stop for the barrier blade may be a static stop that is firmly and immovably anchored, but may also be formed as the end of a second barrier blade.
  • the extinguishing water barrier may further comprise a barrier device which prevents the locking device from opening after the extinguishing water barrier has been triggered.
  • the locking means comprises a slider which cooperates with a stop on the locking element.
  • the mechanical locking element is preferably formed pivotable. As a result, a leverage is generated around the pivot point, with which the clamping unit can better bring the force on the locking element.
  • the locking element is formed with a pivotable about a fixed Drehpol transverse lever and a downwardly extending and pivotable about the transverse lever hook element and the biasing unit is connected to the transverse lever.
  • the retaining element is preferably designed as a hook and stop. This design of the retaining element is less error-prone and can be easily solved by a mechanical actuator.
  • the locking device is preferably modular.
  • the location on the dam barrier to which the locking device is mounted can be freely selected.
  • the locking device further comprises a base plate on which all elements are mounted, wherein the base plate preferably has elongated mounting slots.
  • the locking device may further comprise an interface, for example a plug connection for a removable lever extension.
  • an interface for example a plug connection for a removable lever extension.
  • a lever for example, be added to the locking mechanism and so a much larger force can be applied to the locking mechanism.
  • the "loading" of the locking device is therefore easy to do.
  • Such a lever extension may, for example, be at least 0.5 m, or at least 1 m.
  • the actuating element may preferably comprise an inclined projection which displaces the mechanical locking element in cooperation with a stop. This design allows a nearly error-free operation of the locking element, so that it reliably closes the extinguishing water barrier when folded down without external influence.
  • the locking mechanism preferably further includes a side guide for the locking mechanism.
  • the side guide is plate-shaped and in particular formed as a metal plate and protruding on an L-piece fixed laterally to the base plate, wherein the side guide is formed parallel to the base plate (the directions in which the plate extends).
  • an extinguishing water barrier 10 is shown in an isometric view and in an open or even "loaded” state.
  • the extinguishing water barrier 10 comprises a fastening device 12, a barrier blade 14 and a locking device 20.
  • a fastening device 12 for example, a bolt, a barrier blade, and a locking device 20.
  • a barrier blade 14 for example, a barrier blade, a barrier blade, and a locking device 20.
  • the bottom latching elements 16 are provided, which cooperate with the locking mechanism 20 as will be described later.
  • the fastening device 12 is anchored, for example, by means of screws in the ground and then the dam barrier 14 is pivotally attached to the fastening device 12.
  • the fastening device 12 has a connection to an adjacent one Wall on, so that in any application, the water can get around the fixture 12 around and flows past the extinguishing water barrier.
  • the connection may for example be bricked or may consist of metal profiles, which are then anchored in the wall.
  • the barrier blade 14 in the present case consists of two dam beams with different heights.
  • the number of dam beams and the height of the individual dam beams is irrelevant, provided that the required height of the barrier blade 14 is reached.
  • the barrier blade 14 is pivotally mounted on the fastening device 12. Usually, it is held with an electromagnet 15 in the open position, which is turned off in the application, so that the barrier 14 pivots by its own weight on the ground. However, it is also possible to use a different type of fixture that will release the barrier sheet 14 when activated.
  • a damper 17 or a spring-damper system 17 controls the speed of folding down.
  • a stop on the outer end of the barrier blade 14 is provided on the other side of the hall opening.
  • This stop can be designed to be static, that is, as a receptacle or projection for the end of the barrier blade 14, which then abuts after folding down against the stop and forms a water-impermeable wall.
  • a seal 13 is provided at the end of the barrier blade 14 and on the underside of the barrier blade 14. This seal is compressed in the application to provide the required sealing performance by the later-described locking device 20 of the barrier blade 14 presses against the ground.
  • the stopper is also formed as a barrier sheet 14 ', whereby larger openings in a hall or a walled-in area can be closed.
  • the fastening device 12 ' is just like the fastening device 12 connected to the wall next to the opening, so that even on this side no water on the barrier sheet 14' can flow past.
  • the barrier sheet 14 ' is formed as well as the barrier sheet 14 and then serves as a stop. For this purpose, the two ends of the barrier sheets 14, 14 'formed opposite beveled, as clearly in FIG. 2 can be seen.
  • the brackets 15 ', 15 are triggered.
  • the bracket 15 ' is triggered a predetermined time earlier and releases the barrier blade 14'. For example, this can be done by turning off the power to an electromagnetically designed support and the solenoid has no magnetic force to hold the barrier blade 14 '.
  • the holder 15 ' triggers first, the barrier sheet 14', which is used as a stop which is used for the barrier sheet 14 by the inclination of the tail first in the end position, so that the end of the barrier sheet 14 'below the end of the barrier sheet fourteenth lies.
  • the bracket 15 releases and also causes the barrier blade 14 to pivot downwardly.
  • the locking mechanism 20, 20' closes in each case with the latching elements 16, 16 'anchored in the base.
  • the locking device 20 is a mechanism independent of external conditions. That is, it requires no electricity and no compressed air lines, but is operated purely mechanically and in particular independently by the triggering of the fire water barrier 10.
  • the locking device 20 'corresponds to the locking device 20.
  • the locking device 20 comprises a biasing unit 22, a mechanical locking element 24, an actuating element 26 and a holding and releasing mechanism 28, 26.
  • the locking device 20 is in particular modular, that is, there is a base plate 30, on which all elements of the locking device 20 are mounted. As a result, the locking device 20 can be mounted anywhere on the dam barrier 14, which means great flexibility for the latching elements 16, 16 'to be anchored in the ground.
  • screws 32 may be provided for fastening the base plate 30, for example. These fasten the base plate 30 then through holes in the dam barrier 14, in particular by means of a counter-plate 31 which is fixed on the opposite side of the barrier sheet 14.
  • the counter-plate serves for better fastening, since it assumes a function such as a washer and thus damage to the barrier blade 14 (eg. By tightened nuts or the like) can be avoided.
  • the holes 34 may preferably be formed as slots.
  • the biasing unit 22 is designed here as a spring, in particular as a compression spring. One end of this spring 22 is fastened to the base plate 30, the other to the mechanical locking element 24.
  • the mechanical locking element 24 comprises a transverse strut 25 and a vertically arranged hook element 27.
  • An interface 40 is preferably provided on the cross strut 25, on which a Lever extension (not shown) can be attached.
  • the lever extension may be a simple rod, which may be inserted, for example, in a form of a hollow pipe piece connector.
  • the lever extension is at least 0.5m, preferably at least 1m long.
  • the holding mechanism is formed by a holding element 28, which comprises a projection on the mechanical locking element 24 and a stop 29 on the base plate 30, the release mechanism is formed by an actuating element 26 which in the present case comprises a tapered projection 26 which then abuts against a stop 54 of the Einklinkelements 16 is moved.
  • the cross strut 25 rotates about a pivot 33, which is present on the hook member 27 opposite side of the biasing unit 22. It can also be used in principle a tension spring instead of a compression spring, then the rotational pole 33 and the hook member 27 are on the same side of the tension spring or then the rotational pole 33 is between the tension spring and the hook member 27. This ensures that when activated the Force the biasing unit, the hook member up and the dam barrier 14 is pressed against the ground (or pulled).
  • a side guide 35 is provided to guide the hook element 27 laterally (in FIG. 4 one direction into the drawing plane).
  • the So Internallyhung 35 may be attached to the base plate, but can also be arranged on a bearing plate 36 described below, which can take over even more storage functions.
  • a lock 38 is provided by means of which the mechanical locking element 24 can be held in a locked position.
  • the locking device 38 is preferably designed as a slide, pin or bolt, which is biased by a spring in the direction of the mechanical locking element 24.
  • the spring is preferably disposed within the slider of the locking device 38. in FIG. 4 you can see the slider in the retracted position, in FIG. 6 in the locked.
  • the small finger lever 60 then serves to retract the pin of the lock 38.
  • the mechanical locking element 24 is a stop 39 which can cooperate with the locking device 38 and prevents even at a Malfunction of the spring loosens the hook member 27 and the seal 13 relaxes.
  • the locking lever may be fixed to the bearing plate 36, which extends perpendicular to the base plate 30 and secured thereto. In the present case, the bearing plate 36 is L-shaped and fastened with bores or drill slots on the base plate 30.
  • the locking device 20 In the standby state of the extinguishing water barrier 10, the locking device 20 is biased.
  • a preloaded locking device 20 is in the FIGS. 3 and 4 shown.
  • the cross brace 25 is pivotally mounted on the pivot 33 and the hook member 27 is pivotally mounted on the transverse strut 25 at a second pivot 31.
  • This biasing device 22 is biased in the closing direction of the mechanical locking device 24. In the present case, this is a direction that is mostly vertical, that is to say that the vertical part of the pretensioning device 22 must be larger than the horizontal part.
  • the angle ⁇ In the present embodiment with an elongated compression spring or tension spring 22, the angle ⁇ must be smaller than the angle ⁇ (see FIG. 4 ).
  • the lever extension is preferably attached to the interface 40 and the crossbar 25 is pressed down. Then, the hook member 27 is moved so that the holding member 28 abuts against the stopper 29 and held there (in FIG. 4 to the right). This can be done with a handle 43, for example.
  • the biasing means 22 is biased. This now presses the retaining element 28 against the stop 29, so that the mechanical locking device 24 can not move upwards.
  • the locking device 38 is pulled rearwardly and is biased by the spring in the interior of the slider in the direction of the hook member 27. You can, for example, the hook element 27 rest (see Fig. 4 ) and when the hook element 27 is moved upwards by the pretensioning unit, engage behind the stop 39 (see FIG Fig. 6 ).
  • the locking device 20 is then charged, that is biased and can self-close when the actuator 26 is triggered.
  • the compression spring 22 is compressed and pushes against the crossbar 25 upwards.
  • the holding element 28 is pressed against the stop 29 and the locking mechanism 24 is held in position.
  • the blocking element 38 is biased in the direction of the holding element 28, for example, can easily press on one side of the hook element.
  • the holding element 28 can be detached from the stop 29
  • the triggering of the extinguishing water barrier 10, as shown in the figures, will now be described below. If now the fire-extinguishing water barrier 10 is triggered, the barrier sheet e 14 falls with the locking device 20 down on the latching device 16.
  • the latching device 16 is embedded in the ground and essentially comprises a receiving space 50 for the hook element 27, which is bounded by encircling walls, in particular walls of metal and a hook pin which is adapted to hold the latching hook 45.
  • An upper edge of the receiving space 50 is used as a stop 54 for the actuator 26 in the present embodiment.
  • the distance d from the wall of the latching device to the latching pin 52 should be less than the distance h from the largest end of the projection 26 to the tip of the latching hook 23. This ensures that the pawl hook 45 is also pushed under the pawl pin 52 when the stopper 24 the inclined projection 26, but must not be less than the distance k, which corresponds to the width of the pawl hook 23 at its tip hook (see FIG. 4 ).
  • the downwards movement of the hook element 27 is generated by the dead weight of the barrier blade 14 pivoting downwards, the movement to the left by the movement of the hook element 27 to the left by the cooperation
  • the biasing element 22 presses the cross strut 25 upwards and also pulls the hook element 27 upward. Since the pawl hook 45 has been pushed under the pawl member 52, these two elements are engaged with each other as soon as the hook member 27 moves upward. This locked position is in the FIGS. 5 and 6 shown.
  • the biasing spring 22 pushes the cross strut 25 upwards and therefore pulls the hook member 27 against the pawl and the dam barrier 14 to the ground. As a result, the seal 13 is compressed under the barrier blade 14.
  • the locking member 38 slides under the stop 39. This prevents even in case of malfunction of the biasing member that loosens the hook element, since it can not move down.
