Definitions

  • the present invention relates to a fire protection system comprising a container being filled with a fire extinguishant and containing a detonator, and at least a fuse for guiding activating energy to the detonator, which fuse is arranged at the external side of the container such that the fuse divides said external side in more than two portions as seen in at least one circumferential direction of the container.
  • Such a system is known in the art, wherein a plurality of fuses are mounted onto the outer wall of the container. Each of the fuses extends from the upper side of the container along a side wall to the bottom side thereof. At the bottom side the end portions of the fuses are joint and fixed to the bottom side of the container.
  • the fuses divide the external side of the container in more than two portions as seen in circumferential direction at a location in longitudinal direction of the container.
  • Such a configuration of fuses at the external side of the container increases the probability of contact of one of the fuses with a fire and shortens the delay time between the approach of a fire to the system and the moment of explosion thereof.
  • the prior art system requires a rather complicated manufacturing method.
  • the present invention aims to provide a fire protection system which is simpler to assemble.
  • the fuse is a single fuse wound around the external side of the container.
  • the advantage of this feature is that only a single fuse is necessary to achieve the effect of dividing the external side of the container in more than two portions, hence creating a high fuse density at the external side of the container with only a single fuse. Therefore, it is no longer necessary to separately mount different fuses against the external side of the container in order to achieve that result.
  • the fuse has the function of guiding activating energy to the detonator. In practice this may be a conventional fuse, which burns away such that a flamelet propagates along the path of the fuse towards the detonator, but an alternative guiding member is conceivable.
  • the fuse is wound around the container such that the container is provided with more than one fuse windings, which at least partly follow different paths on the external side of the container, because this can be achieved by a further simplified manufacturing method.
  • several windings may be applied so as to cover a large portion of the external side of the container with the fuse.
  • the distance between the windings is substantially evenly distributed in circumferential direction of the container.
  • the external side of the container may be provided with at least a recess for receiving at least a part of the fuse.
  • This has the advantage that the fuse may submerge at least partly in the recess such that the risk of damaging the fuse is reduced in the case of collision of the container against another object.
  • the fuse when the fuse lies in a recess it is retained on its path around the container, hence minimizing the risk of displacement of the fuse with respect to the container during use of the system.
  • the fuse comprises a moisture-resistant cover which is arranged on the longitudinal outer wall thereof and has a first end portion and a second end portion, between which end portions the fuse is wound around the container, wherein the first end portion communicates with the detonator and projects from the container at a distance from a bottom side of the container, wherein the second end portion ends up at a distance from the bottom side.
  • the moisture-resistant cover is made of a material which is removable by fire and/or has heat conducting properties so as to avoid obstruction of the functioning of the system.
  • the material of the cover may be a plastic, for example, which easily burns away in the case of a fire such that the fire can quickly reach the fuse in order to ignite the detonator.
  • the second end portion ends up near the location where the first end portion projects from the container, because it provides the opportunity to cover both the location where the first end portion projects from the container and the second end portion together, for example against wetting.
  • the fuse has two end portions, between which end portions the fuse is wound around the container, and at least one of these end portions is connectable to the detonator.
  • the fuse may comprise a moisture-resistant cover which is arranged on the longitudinal outer wall thereof, wherein the container has a bottom side, and the end portions of the fuse end up at a distance from the bottom side.
  • At least one of the end portions is provided with a connector part which fits to a counter connector part of an internal fuse communicating with the detonator, because this simplifies the operation for activating the system by the user.
  • both end portions are provided with a connector part, one of those may be used for connecting it to something else, for example to another fuse so as to create a longer fuse which extends from the system to a remote igniter or to one or more other fire protection systems.
  • the counter connector part may end up near the end portions of the fuse. This provides the opportunity to cover both the counter connector part and the first and second end portions together, for example against wetting.
  • the system may comprise connecting means for connecting the fuse to the detonator so as to activate the system, such as described in the European patent application having application number 07100864.3 of the same applicant as the current application. Therefore, the mentioned application is incorporated herein by reference thereto. A second co-pending European patent application of the same effective date as the current application is incorporated herein, as well.
  • EP 0 483 901 B1 discloses a fire protection system including a fuse which is mounted on the external side of the container.
  • the fuse For manufacturing this prior art system the fuse must be put through holes in lugs which are located on the outer wall of the container. It may be clear to the skilled person that this is a time-consuming assembly operation.
  • Fig. 1 and 2 show an embodiment of a fire protection system 1 according to the invention.
  • the embodiment comprises a container 2 which is filled with a fire extinguishant 3.
  • the container 2 also contains a detonator (not shown), which is preferably placed in the middle of the container 2.
  • the detonator is ignited by a fuse 4 for guiding activating energy to the detonator, which fuse comprises a single fuse 4 in this embodiment.
  • the fuse 4 has such a length that it is wound several times around the container 2.
  • the fuse 4 is a so-called fast fuse comprising powder or gunpowder, but may be another type of guiding member for guiding activating energy to the detonator so as to ignite the detonator when the fuse 4 comes into contact with a fire.
  • Fig. 1 shows that the fuse 4 forms three windings around the container 2.
  • the windings of the fuse 4 follow different paths on the external side of the container 2. Due to this winding configuration the fuse 4 divides the external side of the container 2 in six portions as seen in circumferential direction of a side wall of the container 2.
  • the fuse 4 is received in recesses 7 which are provided at the outer side of the container 2.
  • the fuse 4 is guided once through six recesses 7. More windings per recess as well as more recesses 7 are also conceivable.
  • An advantage of the recesses 7 is that the fuse 4 is retained in the desired place on the external side of the container 2, whereas the risk of damage to the fuse 4 is minimized.
  • the embodiment also comprises an internal fuse 5, which extends from the detonator in outward direction of the container 3.
  • the internal fuse 5 projects from the container 2 at an upper side 11 thereof, which upper side 11 is opposite to a bottom side 12 of the container.
  • the fuse 4 has two end portions 8, between which end portions 8 the fuse 4 is wound around the container 2. Both end portions 8 are provided with connector parts 9 which fit to a counter connector part 10 of the internal fuse 5. At least one of these end portions 8 is connectable to the detonator via connector parts 9 and the counter connector part 10. In this way the user can activate or de-activate the system.
  • the fuse 4 comprises a moisture-resistant cover which covers the longitudinal outer wall thereof, and the end portions 8 of the fuse 4 end up at a distance from the bottom side 12. This has the advantage that a core of the fuse 4 is not wetted when the container 2 is put with its bottom side 12 on a wet floor or the like.
  • the counter connector part 10 on the internal fuse 5 ends up near the end portions 8 of the fuse 4 near the upper side 11 of the container 2. Due to this configuration the container 2 can be covered by a container cover 13, such as shown in Fig. 2 . This prevents the end portions 8 of the fuse 4 and the internal fuse 5 from becoming wet when a liquid falls from above onto the container cover 13.
  • Figure 1 shows that the end portions 8 of the fuse 4 are fixed to the container 2 by a tape 14.
  • the end portions 8 are not fixed to the container 2.
  • the moisture-resistant cover may be a coating which is made of a material which is removable by fire and/or has heat conducting characteristics, because it should not obstruct the functioning of the system 1 in the case that it is necessary to extinguish a fire.
  • the coating material may, for example, melt or evaporate quickly when it is in contact with a fire.
  • one of the end portions 8 of the fuse directly communicate with the detonator without a connector to activate or de-activate the system (not shown).
  • the fuse 4 projects from the container 2 at the upper side 11 of the container 2.
  • the other end portion of the fuse which is a loose end in that case, may end up near the location where the fuse projects from the container 2. In that way the upper side of the system 1 can be covered by the container cover 13 such as shown in Fig. 2 .
  • Fig. 3 shows still another alternative embodiment, which differs from that shown in Fig. 1 in that the manner of winding and the location of connector parts 9 is different.
  • One of the connector parts 9 of the fuse 4 is connectable to the counter connector part 10 which is located within a tubular member 15 in this embodiment.
  • the tubular member 15 projects into the container 2, and the detonator and the internal fuse 5 are disposed within the tubular member 15.
  • the tubular member 15 projects outwardly from the container 2 and forms a collar-shaped projection.
  • Fig. 3 shows the situation that the connector part 9 and the counter connector part 10 are connected to each other.
  • the portion of the fuse 4 projecting outwardly from the tubular member 15 is wound from A around the container to B, then wound around at least a portion of the collar-shaped projection to C, from where the fuse 4 is wound around the container 2 to D. Again the fuse 4 is wound around at least a portion of the collar-shaped projection and then the fuse is wound from E to F around the container 2.
  • the invention provides a fire protection system, which can be manufactured relatively simple.
  • the invention is not limited to the embodiment shown in the drawings and described hereinbefore, which may be varied in different manners within the scope of the claims and their technical equivalents.
  • the number of windings is a whole number.
  • the fuse may also follow a non-linear path on the external side of the container to obtain a desired distribution of the fuse around the container.
  • the external side of the container will be covered at least partly by a label or the like further protecting and positioning the fuse and hiding it from sight.
