    BACKGROUND OF THE INVENTION The invention further relates to a method for arranging an automatic shut-off system in a space. BACKGROUND OF THE INVENTION Many shipping containers are used to transport cargo. The containers are locked during transport, when the cargo is closed for several days and even weeks. 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 with a power supply 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 by other containers. Cargo ships have their own extinguishing systems, which usually use water as the extinguishing agent. These extinguishing systems often find it difficult to extend into individual containers in stacks of containers. In addition, the use of water as an extinguishing agent is insufficient if the combustible cargo contains oil, chemicals or batteries.
    O O 25 - CN210205660U, US 2017/0120089 A1 and CN209529941U describe fire extinguishers permanently installed in ro transport containers. Such equipment K is expensive and cumbersome to install and also reduces the space reserved for the container's cargo. Also, fixed fire extinguishers cannot be easily removed from the container, so they are practically useless in the container when the cargo carried in the container is not palletized or flammable. S US 2008/0314602 A1 discloses a portable fire extinguishing device with an N housing containing a container containing a fire extinguishing agent. The outer surface of the housing has nozzles projecting from the surface of the housing. Outside the housing is a heat-sensitive valve which, when heated, opens the extinguishing agent flow path from the tank to the nozzles. The outer surface of the device has permanently mounted magnets that allow the fire extinguisher to attach to the ferromagnetic material. The fire extinguisher described in the publication is intended to be installed in the kitchen above a stove or oven. The heat-sensitive valve located outside the housing and the nozzles protruding from the housing surface make it susceptible to breakage, making the device unsuitable for use in confined spaces. 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 a desired object. In the event of a fire, the heat will melt the perforation in the wall of the housing, releasing the extinguishing aerosol into the surrounding space. The mechanism of release of the extinguishing aerosol based on the bursting of the housing is uncertain. The object of the invention is to provide an extinguishing device and a method by which programs related to the prior art can be reduced. The objects according to the invention are achieved by an extinguishing device and a method which are characterized by what is stated in the independent claims. Some preferred embodiments of the invention are set out in the dependent claims. BRIEF SUMMARY OF THE INVENTION The invention relates to a portable extinguishing device comprising a housing comprising - a wall, an extinguishing unit containing an extinguishing agent inside the housing, an activator for a temperature-extinguishing extinguishing unit and at least one extinguishing agent discharge pipe from inside the housing to the outside of the housing. Said activator is inside the housing and the housing has a flow channel for directing air outside the housing to the activator.

    In another preferred embodiment of the extinguishing device according to the invention, there is a hub connection for connection to an external device, such as an external tripping device. 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 device according to the invention can be connected in series with at least one other extinguishing device. Connection to the series can be done via a hub connection. All extinguishing devices connected in series may be arranged to trip simultaneously or sequentially when one of the extinguishing devices connected in series trips.
    The method according to the invention for arranging an automatic extinguishing system in the space comprises an extinguishing unit containing an extinguishing agent, an activator of the extinguishing unit reacting to a rise in temperature and at least one extinguishing agent discharge pipe controlling the release of the extinguishing agent. In the method, at least one extinguishing device as described above is installed inside the space.
    In a preferred embodiment of the method according to the invention, said extinguishing device is installed in a mobile transport space, such as a sea transport container, a train carriage or a truck trailer. Preferably, said extinguishing device is installed in the mobile transport space during the transport of the cargo and said extinguishing device is removed from the sea container after the transport of the cargo.
    In another preferred embodiment of the method according to the invention, said extinguishing device is installed in a mobile passenger compartment or vehicle, such as a construction site or a caravan.

    N S 30 - 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 top view of a fire extinguishing device according to the invention and Figure 2 shows an exemplary fire extinguishing device according to the invention attached to a surface. 5 - Detailed Description of the Invention Figure 1 shows an exemplary top view of an extinguishing device according to the invention.
    The extinguishing device has a rectangular housing 10 with an openable lid.
    In Figure 1, the housing cover is removed to better illustrate the structure of the device.
    The housing has a base 15, first and second side walls 11a, 11b and first and second end walls 13a, 13b.
    The housing is made of moisture, shock, fire and corrosion resistant material, such as a suitable plastic material or composite material.
    Preferably, the housing is made of a metal such as aluminum.
    Inside the housing there is a protective chamber with a cylindrical wall.
    The wall of the protective chamber joins the bottom from its first edge and its second edge rests against a cover to be installed, not shown in the figure.
    Inside the protective chamber there is a fire extinguishing unit 12 containing an extinguishing aerosol and a switching branch extending through the wall of the protective chamber.
    The extinguishing unit comprises a metallic tank containing a special chemical in a solid state. - Preferably the special chemical contains potassium nitrate.
    An activator generating an electrical impulse that causes the extinguishing unit to trip is connected to the switching branch.
    When the activator trips the extinguishing unit, the special chemical in the solid state is converted in the chemical reaction into an extinguishing aerosol, which is discharged from the tank into the protective chamber, from where it spreads along the discharge pipes outside the housing.
    O 25 Preferably, the extinguishing aerosol comprises powdered potassium carbonate, nitrogen gas, carbon dioxide and water vapor.
    S There are four holes in the wall of the protective chamber, to each of which a discharge E-tube 16 is connected so that the first end of the discharge tube opens into the protective chamber and the second end of the + discharge tube opens outside the housing.
    In the self-destructing device shown in Fig. 1, one end of the discharge tubes opens into the side walls 11a, 11b of the housing so that the other ends are substantially flush with the outer surface N of the side walls.
    One discharge tube is cut off from the portion between the first and second ends of the discharge tube.
    The cutting point has a heat detector chamber 20 so that the cut ends of the discharge tube open into the heat detector chamber.
    The heat detector chamber has a cylindrical wall which joins the bottom at its first edge and the second edge of which rests against the cover to be installed.
    Because the heat detector chamber is connected to the outside of the housing through a severed discharge tube, the temperature in the heat detector chamber and outside the housing is substantially the same.
    Inside the housing 10, an activator 14 of the extinguishing unit is attached to the base 15. The activator 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 an electrical impulse that triggers the extinguishing unit.
    The electric pulse trigger is triggered when the heat-sensitive element 17 at its tip heats up above the trigger temperature of the trigger.
    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 extends through a hole in the wall of the heat detector chamber inside the heat detector chamber.
    Preferably, the electrical pulse trigger can be a TAG pulse device marketed by Salgrom Technologies Oy.
    The electrical impulse device is connected by a first cable 19a to a connection housing 32, which in turn is connected by a second cable 19) to the connection branch of the shut-off unit 12.
    In connection with the connection box, there is a hub connector 30, by means of which the extinguishing device can be connected to an external device, such as an external tripping device.
    With the help of the hub connector, several extinguishing devices can be connected in series so that all extinguishing devices connected in series are triggered substantially simultaneously or in series when the electrical impulse trigger of one extinguishing device trips.
    In addition, there are two mounting magnets 26 inside the housing, by means of which the extinguishing device is intended to be mounted on a ferromagnetic surface.
    The mounting magnets are S 25 polygonal pieces with several flat surfaces.
    The mounting magnets N are attached to the end walls of the housing by a handle 28 having a first portion extending inside the housing and securing to the mounting magnet S and a second portion extending outside the housing S.
    The mounting magnets have holes 18 in the bottom.
    S The gripping surface of the mounting magnet in this position may grip the surface of a piece of ferromagnetic material on the outside of the housing, such as the wall of a shipping container.
    Correspondingly, by turning the handle, the mounting magnets can be turned to another position in which the gripping surface of the mounting magnet bends at an angle from the plane of the base, whereby the mounting magnet detaches from the ferromagnetic surface.
    Inside the housing, there is also a box inside which the wireless communication means 24. The communication means comprise an antenna and a transmitter / receiver which can operate in a wireless communication network, such as a 4G or 5G mobile network, WLAN, NB-lot, Zigbee , On a LoRa or Bluetooth network.
    Inside the box is a battery for storing the electrical power needed by the communication media.
    Fig. 2 shows an exemplary side view of the extinguishing device shown in Fig. 1 attached to a ferromagnetic surface 100.
    The extinguishing device according to the invention is a continuously operational device, all functional parts of which are housed inside a housing 10 provided with an openable lid 21.
    The housing has no handles 28 except for any protruding parts.
    The extinguishing device is attached by mounting magnets to a ferromagnetic surface, for example a steel plate, by placing the housing base 15 against the ferromagnetic surface and turning the mounting magnets 26 by turning the handles so that the gripping surfaces of the mounting magnets protrude slightly from the bottom holes.
    Immediately after installation, the fire extinguisher is in working order.
    If the need for extinguishing ceases or changes, the extinguishing device can be easily removed by turning the handles 28 so that the mounting magnets detach from the ferromagnetic surface.
    If there is no ferromagnetic surface in the space where the extinguishing device is installed, the extinguishing device can be secured in place with cloths, ropes, straps, hanging hooks or screw fastening.
    The extinguishing device does not necessarily have to be fixed at all, but can simply be placed on a level or floor, for example.
    S 25 - The outer surface of the housing wall has a heat-activated label 36 that changes color N or appearance when the temperature of the label exceeds the tripping temperature of the extinguisher. re The lamp-deactivable label thus acts as an indicator means to tell the user of the device whether S the extinguishing device is in working order or whether the extinguishing device contained therein has tripped.
    A tripped shut-off device can be restored to operation by replacing it with a new activator and shut-off unit.
    By means of the extinguishing device according to the invention, an automatic N extinguishing system can be formed in any space simply by placing the state N one or more extinguishing devices.
    The extinguishing devices placed in the space can operate independently or they can be connected in series by means of a hub connection.
    An alternative to serial connection via a hub connection is to place the extinguishing devices in a space such that
    that the hot gas jet discharged from one triggering fire extinguishing device is directed to the discharge pipe leading to the heat detector chamber of the adjacent second extinguishing device. In this case, the tripping of the first extinguishing device causes the adjacent extinguishing device to trip faster than would occur due to an increase in the general temperature of the room. Em. The firing of the extinguishing device carried out in this way is called hot gas ignition. The extinguishing device in particular can be used to create an automatic extinguishing system in an enclosed space, such as a sea container, a train wagon, a truck trailer or a construction site. Inside a shipping container, trailer or construction site - attach at least one fire extinguisher so that in the event of a fire, the extinguishing agent can spread from the fire extinguisher to the entire interior of the space. The fire extinguisher can be mounted on the walls, ceiling, door or floor of the room. The fire extinguisher may be attached to a container during the carriage of flammable or flammable cargo in a sea container or trailer and may be removed from the container or wagon after the carriage has been carried. The extinguishing device in particular is suitable for creating an automatic extinguishing system for containers and wagons carrying cargo containing charged batteries, such as electric cars. Some preferred embodiments of the portable extinguishing device and method 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
