Definitions
- the invention relates to a device according to the preamble of the claim 1 and uses of this device according to claims 7 and 8.
- PCT / CH 01/00319 contains a storage tank that is filled or can be filled with an active ingredient described.
- the device had a pyrotechnic propellant in one first end region of the storage tank.
- the nozzle was in line with the longitudinal axis of the storage tank arranged.
- the device served mainly as a self-defense weapon, but should also be a variant for automatic fire fighting can be used.
- GB-A 937 023 describes one to be used as a flamethrower or fire extinguisher three-part storage unit described.
- the unit had a U-shaped tank with a screwed-on outlet nozzle on one of the two leg ends.
- the outflow direction of the active ingredient from the nozzle was in the longitudinal axis direction.
- an exchangeable gas generation tank was screwed on.
- This U-leg was only partially filled with active liquid in such a way that up to Leg space left a free space.
- the liquid was elastic towards the free space Ball or other similarly acting elements closed.
- a fire-fighting device is described in US Pat. No. 5,660,236. This device had a storage tank filled or capable of being filled with an active ingredient (3) .
- the active substance could be expelled from the storage tank head by means of a sabot moved by a pyrotechnic propellant.
- a room was nebulized around the storage tank head, in the jacket of which radial wall openings were arranged.
- the object of the invention is to provide a compact, inexpensive device, with which a room area can be automatically misted.
- the device can serve to prevent unauthorized persons like burglars, vandals, ... to keep away from an object or by using a Fire protection means to protect the object against fire.
- an irritant liquid or an irritant gas can be used as the storage tank charge (active ingredient) be used; however, powdery substances can also be used. With powdery However, fabrics must be provided with guide elements, so that they are guided around bends is guaranteed around.
- liquid active substances can, for example, be used as liquid active substances be used:
- Capsaicin is an extract from the chilli pepper plant, which is usually with a Concentration between 1% and 4% is dissolved in alcohol. Capsaicin leads to sudden, temporary inflammation of all mucous membranes with which it comes into contact (e.g. eyes, respiratory tract). Capsaicin works in both humans and animals. in the In contrast to the Lacrimonium listed below, it leads to the involuntary Closing eyes.
- a CS solution can be used as an additional liquid charge (active ingredient).
- CS is a tearful lacrimonium. A strong effect is created as an additional effect Itching on the skin. CS only works in humans.
- CN solutions can also be used. CN causes nausea. It works however slower than a CS or capsaicin solution.
- Stink secretions can also be used as liquid charges. Most Smelly secretions also lead to nausea.
- CS and CN can also be used in gaseous form instead of a liquid charge.
- Capsaicin It is z. B. Gels. Dyes can also be added later Identification or marking of a perpetrator can be used.
- the device is particularly well suited for fire protection in closed rooms, for example in an engine or cargo hold.
- water can be used as the active ingredient.
- a dense water mist consisting of tiny water droplets (aerosol) is then expelled from the nozzles of the vaporizing tube of the device under high pressure in a fraction of a second.
- This water mist spreads very quickly in the burning engine or cargo hold and extinguishes the fire on the one hand by deoxygenation (suffocation) and on the other hand by cooling the source of the fire.
- the fine water droplets form a very large surface and thus draw a lot of heat energy from the fire, which quickly cools the source of the fire.
- About 1.5 m 3 of water vapor is produced from one liter of water.
- the nebulization nozzles need not be directed directly at the source of the fire.
- the water vapor generated by the fire spreads quickly in the closed room and indirectly extinguishes the fire.
- the installation can have a second arrangement of devices.
- the device according to the invention is or a system with several of these devices no longer connected to an extinguishing agent pipe network connected.
- the extinguishing agent is in the device with a predetermined Volume.
- a sprinkler system also only has the network pressure available, the device according to the invention, however, has a pyrotechnic propellant charge explosively builds up gas pressure to expel the extinguishing agent after ignition, so that the discharge can take place in about 20 ms. Since the device according to the invention is independent of a pipe network, it can be independent of location, such as used in vehicles, containers, containers, shipping boxes, ... Also results significantly better room fogging thanks to the fog units shown below than with conventional sprinkler systems.
- the device according to the invention has a substance filled or fillable storage tank and a pyrotechnic propellant charge in a first end area of the storage tank. Furthermore, the device has a sabot to expel the Active ingredient from the tank. The sabot is ignited by the propellant gases Propellant charge against the end of the tank, which is not identical to the position of the nozzles, movable. The nozzles are in a misting unit arranged at the tank end area arranged such that the active substance flow which can be set in motion by the sabot diverted in the second tank end area and then into the obstruction pipe is transferred. Furthermore, the device has at least one ignition command transmitter, preferably a sensor that serves to initiate the pyrotechnic propellant charge. Depending on Operating conditions of the device, the ignition command transmitter is selected. Through the The configuration described here is no longer vaporizing a room area limited the storage tank head end area. The area to be nebulized can now can be freely chosen.
- an ignition command device So-called fire alarm is used, which responds to temperature or smoke. Should the The device as object protection against burglars, vandals, ... is the ignition command a vibration sensor, proximity sensor, glass break sensor, .... In both In some cases, a non-automatic triggering can also take place. In this case e.g. television monitoring may be provided. The observer, who then via TV picture detects the application, then a manual release via a Make "ignition switch" as the ignition command transmitter.
- the inventive Device now a nebulizer tube with several outlet nozzles in the Pipe casing.
- the active ingredient is no longer sprayed in the direction of Attackers, opponents, ... Instead, a space area is nebulized.
- One of the ends of the nebulization tube is on a second, the first arranged facing away from the tank end area and extends from this. The The course of the vaporizing tube can thus take place in such a way that an optimal vaporizing of space.
- the outlet nozzles will preferably be designed in such a way that an active substance emerges not in the extension of the longitudinal axis of the storage tank.
- the drug was always released in such a way that it usually elongated storage tank was made at the top of the head. Here, however, is going straight the active ingredient leakage on the head side avoided. It’s even preferable to If there are several outlet nozzles, arrange them straight from the top.
- a room area should be well nebulized, the Arrange exhaust nozzles over a longitudinal area. When used against one Opponents may find it advantageous to direct the active ingredient against them. With one automatically working device, where the location of the opponent or fire is not known, it is advantageous to fog a room area. You have therefore consciously the outlet nozzles not placed in the immediate vicinity of the second tank end area (head side).
- the device is preferably no longer used alone, but in arrangements use multiple devices.
- the Devices are now designed in such a way that they are modular in such a way that they are problem-free in a "parallel connection" as well as in a series connection can.
- a series connection has the advantage that with only a single ignition command transmitter (Sensor) several devices can be "fired” one after the other. hereby there is a relatively inexpensive arrangement, as a rule Sensor is the most complex and therefore the most expensive element of the arrangement.
- the serial arrangement (Cascade row) of the devices is useful, for example, in a fire suppression arrangement in the cargo hold of a road train.
- the devices would one prefers to attach to the cargo hold ceiling.
- one to several rows of cascades are installed per cargo hold or trailer. The effort for the electrical contacting from the sensor is very low, since each only at one end of the cascade.
- the parallel arrangement of the devices can be displayed.
- the single ones Devices are installed separately and separately with one "Ignition cable" contacted from the sensor.
- the high flexibility in parallel installation requires more effort for the electrical connection with the sensor or sensors.
- Each storage tank is with one Storage tank cap closed.
- a first one Storage tank an electrically ignitable propellant.
- the cap of this storage tank is however removed and in its place a coupling piece is attached, with the a second storage tank can be flanged.
- This second storage tank then has none electrically ignitable propellant, but a mechanically ignitable, by a Impact of the sabot of the first device is ignited.
- a third, etc. device can then be flanged on.
- further device is in each case by the kinetic Energy of the sabot of the upstream device ignited.
- both the first and the second tank end area have a thread on that both a retaining cap for a pyrotechnic, in particular a electropyrotechnical propellant charge, as well as a coupling piece for coupling a first tank end area of another storage tank can be screwed on.
- the storage tank Since a room area is to be nebulized, the storage tank is stretched out long, in particular with a circular cylindrical cross-section, and form the atomizing tube Arrange along the storage tank jacket.
- the fogging tube can then run as a "bracket" outside the storage tank. But you can also "envelop” the storage tank with an outer tube, which then in its jacket the Exhaust nozzles.
- the storage tank has first and at the second tank end area a laterally protruding nozzle with a first flange and the "bracket tube at its tube ends each a second, to the first Flanges matching flange.
- a release agent is arranged, which in the unignited state of the propellant charge prevents penetration of the active ingredient into the nebulizing tube and when ignited of the propellant charge due to the pressure build-up in the active ingredient breaking the active ingredient into the nebulizing tube allows to enter through the nozzles.
- the device 1 according to the invention shown in FIG . 1 has a storage tank 5 filled with an active ingredient 3 , an electrically ignitable pyrotechnic propellant charge 6 and, as a unit for atomizing the active ingredient 3, a nebulizing tube 7 .
- the storage tank 5 is designed here, for example, as a tube with a circular cylindrical cross section.
- the propellant charge 6 is arranged in a first end region 9 of the storage tank 5 .
- the propellant 6 is designed as an electrically ignitable pyrotechnic gas generator 10 and held in a retaining cap 12 screwed onto the end region 9 .
- the gas generator 10 is ignited via the two cables 11 . Furthermore, there is a sabot 13 which is driven away from the propellant 6 into the storage tank 6 against the active substance 3 by the gases arising after the ignition.
- the active ingredient 3 Due to the pressure of the gas acting on the active ingredient 3 , the active ingredient 3 is pressed into the nebulizing tube 7 with a deflection of the active ingredient flow and is pressed into an adjacent room area 14 through its outlet nozzles 15 arranged in the jacket, forming a nebulization.
- This process is indicated in FIG. 2 , the movement of the sabot 13 being indicated by the arrow 16 . Only through the deflection of the active substance flow, which is avoided in the prior art, and a corresponding arrangement of the outlet nozzles, is it possible to select the space area intended for nebulization.
- the outlet nozzles 15 are arranged here in a row, for example.
- the nozzle outlets are directed away from the longitudinal axis 5 of the storage tank 5 .
- One of the ends of the nebulization tube 7 is arranged on a second tank end region 19 facing away from the first 9 such that it extends from this.
- the outlet nozzles 15 are designed in such a way that an active substance does not escape in the extension of the longitudinal axis 17 of the storage tank.
- the outlet nozzles 15 are also not in the immediate vicinity of the second tank end 19.
- the device 1 shown in FIGS. 1 and 2 has a blind connector 21a with a flange connection 21b on the first storage tank end region 9 .
- the blind connector 21a has no connection to the interior 22 of the storage tank ; he only has a stop job.
- At the second storage tank end area 19, which lies opposite the first storage end area 9 there is also a further connection piece 23a with a connecting flange 23b . Both nozzles 21a and 23a point in the same direction and run parallel to one another.
- the connecting piece 23a opens into the storage tank interior 22.
- the vaporizing tube 7 is designed like a bow and has two connecting flanges 15a and 25b that match the connecting flanges 21b and 23b .
- the flanges 23b and 25a are screwed together in a fluid-tight manner by means of a sealing element (for example an O-ring).
- a so-called rupture disk 27 is clamped in between the flanges 23b and 25a , which prevents the active substance 3 from penetrating into the atomizing tube 7 .
- This rupture sheath 27 can also be used for sealing instead of the sealing element. Only when the propellant charge 6 has been ignited does the rupture disc 27 burst due to the pressure build-up in the active ingredient 3 through the sabot 13. Since the rupture disc 27 is firmly clamped at its edges between the flanges 23b and 25a , it remains in place and in the burst state Job. No pane parts are torn off, as a result of which the outlet nozzles 15 cannot be blocked.
- the second end region 19 is closed with a tank cap 29 .
- Both the first and the second tank end regions 9 and 19 have an identical external thread 31 and 32, respectively.
- the propellant charge 6 and the tank cap 29 also have the same internal threads 33 and 34 that match the threads 31 and 32. The advantage resulting from this is explained below.
- FIG. 3 shows a parallel connection of four devices 1a-1d , which are electrically connected to a sensor 35 as an ignition command transmitter via cables 11a-11d .
- sensor 35 instead of sensor 35 , only one ignition switch can be used. If the system is to be used as object protection against vandalism, burglary or other acts of violence, a proximity sensor, glass breakage sensor, vibration sensor, etc. is used as sensor 35a .
- the devices are then filled with a corresponding active ingredient, as mentioned at the beginning. Not all devices 1a-1d need to be filled with one and the same active ingredient; different fillings can also be used depending on the desired effect.
- devices 1a - 1d will be filled with water, CO 2 or another extinguishing agent.
- the devices Differentiate the devices to be used in a cascade arrangement only slightly different from those used in a parallel connection. Since the Devices are modular, the devices can be related to parallel or convert cascade arrangement into each other in a simple manner.
- FIG. 5 shows a cascade arrangement of two devices 1e and 1f arranged one behind the other.
- the device 1e largely corresponds to the device shown in FIGS. 1 and 2 .
- the same elements are therefore identified by the same reference numerals.
- To connect the two devices 1e and 1f only the tank cap 29 is replaced by a coupling piece 37 and a pyrotechnic propellant charge 39 which can be ignited by a mechanical impact of the sabot 13 of the device 1e .
- the propellant charge 39 consists of a holding element 40 in which a mechanically ignitable gas generator 41 is held.
- the holding element 40 is designed with a circular cylindrical cross section and can be inserted into the interior 22 of the device 1e at the second end region 19 until an annular end edge 43 rests on the end face 45 of the end region 19 .
- the outer casing 46 of the holding element 40 is sealed with two sealing rings 47a and 47, which lie in grooves 49a and 49b in the outer casing 46 , with respect to the inner surface 50 of the interior 22 .
- the holding element 40 has a central inner bore 51 which has a groove 53 for a sealing ring 54 in its end region facing away from the edge 43 .
- the holding element 40 also has two "secant bores" 55a and 55b running parallel to one another.
- the secant bores 55a and 55b extend from the outer casing 46 to the inner bore 51 on its inner surface approximately tangentially past back to the outer casing 46.
- a supporting pin is inserted 57a and 57b, which then engages the outer groove 59 to the gas generator 41, to hold it in the holding element 40 .
- the gas generator 41 also has a circular cylindrical cross section. It has an impact pin 61 on its end face 60 projecting into the interior 22 of the device 1e .
- the pyrotechnic gas generator 10 of the propellant charge 6 of the device 1e is electrically ignited by a signal from the sensor 35b , it sends explosive gas into the interior 63 of the sabot 13, whereby the gas generator 10 drives it in the direction of the arrow 16 in the manner of a bullet.
- the rupture disc 27 bursts, the active ingredient 3 shoots into the nebulization tube 7 and emerges vaporizingly from the outlet nozzles 15 .
- the end face 65 of the sabot 13 hits the impact pin 61 of the gas generator 41 of the propellant charge 39 of the device 1f , whereby this is ignited and gas now explodes into the interior 63 of the sabot 13 of the device 1f ( see Figure 7).
- This sabot 13 is now pressed like a bullet against the active substance 3 of the device 1f , whereby it is driven out analogously to that of the device 1e . This process is repeated until the active ingredient of the last device, here the device 1h, is expelled.
- the device 1h then has the tank cap 29 shown in FIGS. 1 and 3 .
- a pressure relief can be provided, as described in PCT / CH 01/00319 and shown in particular in FIG. 3 there .
- a relief region 67 which contains the nozzle 23a , of the storage tank 5 and is located in front of the second end region 19 is provided with an inner diameter which is larger than the outside diameter of the sabot 13 .
- the axial length of this relief area 67 is also greater by a tolerance than that of the sabot 13. If the sabot 13 now reaches the relief area 67 while the active ingredient 3 is being expelled, the propellant gas can flow into the vaporizing tube 7 between its outer wall and the inner wall of the area 67 and exit through the outlet nozzles 15 for complete pressure relief.
- the "secant holes” do not have to run parallel; they can enclose any angle with each other. There also need not be two secant holes and two support pins; more can also be provided. A clamping ring can also be used for mounting, which then snaps into the groove 59 .
- the embodiment described above has proven itself due to its simple manufacture and assembly.
- the atomizing tube 7 is described above as a tubular bracket. Such a design is advantageous with a robust design of the device. However, other designs can also be made.
- the nebulization tube can also be designed as a jacket tube around the storage tank 5 . But you can also design the Vebelebelungsrohr as a protruding tube, which is only attached to the end portion 19 .
- the fog tube does not have to have a circular cross-section; Any cross-sections, such as in the form of a square tube, an elliptical tube, ... are possible. If you choose a protruding pipe, it does not have to be protruding; it can be bent as desired.
- the storage tank 5 does not necessarily have to have a circular cylindrical cross section.
- the interior of the store only has to be designed in such a way that a sabot can be moved to expel the active substance. This means that elliptical and polygonal cross sections are possible by adapting the shape of the sabot.
