    FIELD OF THE INVENTION The invention relates to an extinguishing system comprising a housing, an extinguishing unit containing at least two extinguishing agents and an activator for at least one extinguishing unit responsive to a rise in temperature, the extinguishing units and the activator (s) being inside the housing. Background Art - Most autonomous fire extinguishing systems on the market today are fixed, mains-operated or other power supply systems. In confined spaces, installing fixed systems is slow and cumbersome. Fixed installations and dismantling are expensive and require special expertise.
    - Sea containers used for cargo transportation are particularly challenging fire protection sites. Cargo carried in sea containers may contain substances or equipment which may catch fire during handling or transport of the container. Particularly flammable cargo is various chemicals and electrical appliances in which the power supply is in place. Extinguishing a fire in a sea container is particularly difficult because - the burning container may be located far on the deck of a ship at sea, surrounded tightly by other containers.
    Cargo ships have their own extinguishing systems, which usually use water as the extinguishing agent. Cargo ship extinguishing systems are out-of-container systems that are often difficult to extend into individual containers in stacks of containers. S 25 - In addition, the use of water as an extinguishing agent is insufficient if the combustible cargo contains oil, chemicals or batteries.
    LO v CN 210205660 U, US 2017/0120089 A1 and CN 209529941 U describe extinguishing systems permanently mounted on E transport containers. Such equipment - is expensive and cumbersome to install and also reduces the amount of space reserved for the container's cargo. Also, fixed fire extinguishers cannot be easily removed from the container, so that they N are practically useless in the container when the cargo carried in the container is not flammable or flammable. US 2008/0314602 A1 discloses a portable fire extinguishing device with a housing containing a container containing a fire extinguishing agent. The outer surface of the housing has nozzles projecting from the surface of the housing. The outer surface of the device has permanently mounted magnets that allow the extinguisher to attach to the ferromagnetic material. CN 204655839 describes an automatic fire extinguishing device comprising an extinguishing aerosol placed inside a closed housing. One wall of the housing has an adhesive surface that allows the housing to be attached to the desired destination. From individual extinguishing devices, a system comprising several extinguishing devices can be built in an enclosed space, for example in a sea container, but the installation of such a system in a container during cargo unloading and unloading from the container after transporting the cargo is laborious and slow.
    - The object of the invention is to provide a shutdown system with which the programs related to the prior art can be reduced. The objects of the invention are achieved by an extinguishing system which is characterized by what is stated in the independent claim. Some preferred embodiments of the invention are set out in the dependent claims.
    BRIEF SUMMARY OF THE INVENTION The invention relates to an extinguishing system comprising a housing, an extinguishing unit containing at least two extinguishing agents and an activator for at least one extinguishing unit responsive to a rise in temperature, the extinguishing units and the activator (s) being inside the housing. The housing is elongate in shape and the extinguishing units are spaced apart inside the housing. Preferably, the housing is a tube having a substantially rigid wall. Alternatively, the housing may be a hose or a sock with a flexible wall. Furthermore, the housing may comprise both rigid tubular wall portions and flexible tubular wall portions.
    o In a preferred embodiment of the extinguishing system according to the invention, the wall of the O 25 housing has holes for the discharge of the extinguishing agent.
    S In another preferred embodiment of the extinguishing system according to the invention, the activators are in a housing in the space between the extinguishing units.
    In a third preferred embodiment of the extinguishing system according to the invention, said activator is an electric pulse trigger operating without external energy. The electrical impulse trigger stores mechanical energy that is released when the activator is triggered and produces an electrical impulse that triggers the shutdown unit.
    Yet another preferred embodiment of the extinguishing system according to the invention comprises a plurality of activators which are connected in series by cables to trigger all the activators simultaneously.
    In another preferred embodiment of the extinguishing system according to the invention, the at least one extinguishing unit contains a quenching chemical in a solid state. The quenching chemical in the solid state is converted to a gaseous aerosol when the quenching unit is activated by the activator.
    In a further preferred embodiment of the extinguishing system according to the invention, the at least one extinguishing unit contains a fire-extinguishing or cooling - gas, liquid or powder. The gas may contain argon, nitrogen and / or carbon dioxide. Yet another preferred embodiment of the extinguishing system according to the invention comprises detection means for indicating the tripping of the extinguishing unit. Preferably, said detector means comprise a heat-activated label on the wall of the housing. Alternatively or in addition, said detection means may comprise wireless communication means inside the housing.
    In a further preferred embodiment of the extinguishing system according to the invention, the housing has fastening means, such as a strap, a collar or a fastening magnet, for fastening to the structures of the space to be protected or to the object to be protected from fire.
    Another preferred embodiment of the extinguishing system according to the invention is arranged to operate without an external energy source. In this embodiment, the parts belonging to the device may be mechanical in principle, or the device may have its own power supply to which the device can operate independently for the planned operating time by means of the stored electric current.
    No. 25 - In another preferred embodiment of the extinguishing system according to the invention, there is a hub connection for connection to an external device, such as an external trip device I. The hub interface comprises at least one known communication port, e.g. a USB port, an Ethernet interface or a PCMCIA interface.
    Another preferred embodiment of the extinguishing system according to the invention is N 30 - connectable in series with at least one other extinguishing system. The connection to the N series can be made using a hub connection. All extinguishers connected in series may be arranged to trip simultaneously or sequentially when one of the extinguishers connected in series trips.
    The advantage of the invention is that it can be installed quickly and easily on an object to be protected. Disassembly of the extinguishing system from the site is also quick. In addition, the invention has the advantage that it is reliable and mechanically durable, since it operates without external energy and all the parts belonging to the device are located inside a wall which protects against mechanical stress. A further advantage of the invention is that it can be easily scaled to different sized spaces by varying the size and number of individual extinguishing units included in the system. BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in detail. In the description, reference is made to the accompanying drawings, in which Figure 1 shows an exemplary extinguishing system according to the invention, taken from above, and Figure 2 shows an exemplary embodiment of an extinguishing system of the invention, taken from above, by way of example. DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows by way of example an extinguishing system according to the invention, taken from above. The extinguishing system comprises an elongate housing 10 having a substantially rigid wall. The housing is thus a rigid-walled tube. The housing length S can be selected to design the extinguishing system according to the application. Preferably, the housing is 2-6 meters long. The housing wall has holes 24 which allow air to flow from the outside of the housing into the housing and the extinguishing agent from the inside of the housing to the outside of the housing, respectively, as described below. The ends of the housing can be closed or open. The housing can be made of plastic or metal, such as aluminum.
    W D There are 12 fire extinguishers inside the case. The distance between adjacent N extinguishing units can be 0.5-2.5 meters. The extinguishing unit comprises N metal tanks containing a special chemical in a solid state. The special chemical is in a normal state inside the tank in a stable state and at normal atmospheric pressure. Preferably, the specialty chemical contains potassium nitrate. Each extinguishing unit is connected by a fire-resistant cable 16 to an actuator 14 which triggers the extinguishing of the extinguishing unit. In Figure 1, each activator is connected to only one shutdown unit. However, each activator can be connected to more than one extinguishing unit, even so that each activator is connected to each extinguishing unit in the same housing 10. When the activator trips the extinguishing unit, the special chemical in the solid state is converted in the chemical reaction to an extinguishing aerosol which is discharged from the container into the housing, from where it flows through the holes 24 in the housing wall to the outside of the housing. Preferably, the quench aerosol contains powdered potassium carbonate, nitrogen gas, carbon dioxide and water vapor. The activator 14 of the extinguishing unit is an electromechanical electrical impulse trigger known per se. The electrical impulse trigger stores mechanical energy, which is released when the activator is triggered and produces a tripping - electrical impulse of the extinguishing unit. The electric pulse trigger is triggered when the heat-sensitive element at its tip heats up above the trigger temperature of the activator. The trigger temperature of the activator may be 70-110 ° C. The electric pulse trigger is placed in the housing so that the heat-sensitive element at its tip is in contact with the air inside the housing. Preferably, the electrical pulse trigger can be a MIL-TAG pulse device marketed by Salgrom Technologies Oy. At least one actuator has a hub connector 30 that allows the fire extinguisher system to be connected to an external device, such as an external trigger. By means of the hub connector, several extinguishing systems can be connected in series so that all extinguishing systems connected in series are triggered substantially simultaneously or sequentially when one extinguishing system activator is triggered.
    O> The outer surface of the housing wall has a heat-activated label that changes color or 7 when the temperature of the label exceeds the tripping temperature of the fire extinguisher. > The lamp-deactivated label thus acts as an indicator 20 which tells the user of the appliance = whether the extinguishing system is operational or whether the extinguishing units contained in it have been triggered. A tripped shut-off system can be restored to operation by replacing it with new activators and shut-off units.
    N N The outer surface of the housing is spaced apart by other fastening means 22 in the form of straps, by means of which the fire extinguisher system can be fastened or hung in the space or object to be protected.
    Wireless communication means 18 are housed within the housing. The communication means comprise an antenna and a transmitter / receiver capable of operating in a wireless communication network, such as a 4G or 5G mobile network, a WLAN, an NB-lot, a Zigbee, a LoR or a Bluetooth network.
    The communication means comprises a battery for storing the electrical current required by the communication means.
    The data transmission means are connected by wires to the activators 14 so that when the activator is triggered, the data transmission means sends information about the trip to a predetermined destination, for example a mobile telephone number or an IP address.
    Figure 2 shows by way of example a preferred embodiment of a fire extinguishing system according to the invention.
    In this embodiment, the housing 10a is a hose having a flexible wall with holes 24. The wall may be made of a fire-resistant fabric or some other flexible material.
    In other respects, the extinguishing system is similar to the system shown in Figure 1, i.e. it includes extinguishing units 12 housed inside the housing, which are connected by cables 16 to the actuators 14, the detector 20, the hub connector and the communication means 18. Thanks to the flexible housing it is easy to place in a confined space close to a fire-sensitive object.
    The housing has straps acting as fastening means 22 by means of which the extinguishing system can be hung in a space or object to be protected from fire.
    By means of the extinguishing system according to the invention, automatic fire protection can be established in any space simply by placing the one or more extinguishing systems.
    Spaced-out extinguishing systems can operate independently or be connected in series via a hub interface.
    An alternative to the series connection by means of a hub connection is to place the extinguishing systems partially parallel or intersecting so that the hot gas jet discharged from one triggering fire extinguishing system is directed to the adjacent other fire extinguishing system.
    In this case, the tripping of the first extinguishing system causes the adjacent N extinguishing system to trip faster than the general temperature of the room would happen.
    I The extinguishing device is particularly well designed to create an automatic extinguishing system for an enclosed space, such as a sea container, a train wagon, a truck trailer or a construction site.
    At least one extinguishing system is attached to the inside S of the shipping container, trailer or construction site so that in the event of a fire, the extinguishing agent can spread from the extinguishing system to the entire interior of the room.
    The extinguishing system can be installed on the walls, ceiling, door or floor of the room.
    The extinguishing system can also be installed outside the protected object or space.
    In this case, the extinguishing units can be triggered by means of external triggers connected to the activators and the extinguishing agent is led to the target via separate pipes or ducts. The extinguishing system may be attached to the container during the carriage of flammable or flammable cargo in a sea container or trailer and removed from the container or wagon after the carriage of the cargo. The fire-fighting system is particularly well suited to providing automatic fire protection for containers and wagons carrying cargo containing charged batteries, such as electric cars. Some preferred embodiments of the extinguishing system according to the invention have been described above. The invention is not limited to the solutions described above, but the inventive idea can be applied in various ways within the limits set by the claims. O OF O OF
