EXTINGUISHING DEVICE AND METHOD OF USING THE EXTINGUISHING DEVICE

WHY

Field of invention

[0001] This invention relates to an extinguishing device comprising an extinguishing fluid source, an outlet for supplying extinguishing fluid, a movable punch and a mounting arrangement for attaching the extinguishing device to a surface.

Description of the prior art

[0002] It is known to use various automated extinguishing systems in various closed spaces, for example in transport and storage spaces for goods, in order to contain or extinguish fires that break out. These known extinguishing systems are typically based on feeding an extinguishing agent, such as water, into the space in question through a nozzle system arranged inside it. In this case, the extinguishing system is typically connected to a wider system outside the space, for example to supply the extinguishing agent or the electric current required for the extinguishing system's operation to the extinguishing system.

[0003] Due to these characteristics, the problem of the extinguishing systems in question is the laborious installation method they require, whereby, for example, in order to connect the extinguishing system to an external system, it is often necessary to make different penetrations in the target space. On the other hand, such extinguishing systems also require a continuous connection to an external system in order to function. Due to the reasons mentioned, these known fire extinguishing systems are particularly poorly suited for firefighting in spaces intended to be moved, for example marine vessels used in the transport of goods

N 25 roads, in the case of which switching the extinguishing system to an external one

N to the system, or making pass-throughs or other changes inside space 3 is out of the question. In these cases, even going to the target space 2 is often not possible.

I

E Summary of the invention

S 30 [0004] The purpose of this invention is to solve the problems explained above and to provide an extinguishing device that enables fire protection

In confined spaces without laborious installation steps or connection to external systems of the extinguishing device. This goal is achieved with the extinguishing device according to independent claim 1 and the method according to independent claim 15.

[0005] By forming the extinguishing device to be attached to the surface and further in such a way that it comprises a source of extinguishing fluid, an outlet for supplying extinguishing fluid from the extinguishing device and a movably arranged diagonal, an extinguishing device that is easy to install and works without external systems or changes to the target space is obtained.

Brief description of patterns

[0006] The invention is explained below by way of example in more detail with reference to the attached figures, of which:

[0007] Figure 1 shows a surface-mounted extinguishing device viewed obliquely from above,

[0008] Figure 2 shows a cross-section of the diagonal arm of the extinguishing device of Figure 1, viewed directly from the side,

[0009] Figure 3 shows another embodiment of a surface-mounted extinguishing device, and

[0010] Figure 4 shows the third embodiment of the extinguishing device attached to the surface.

Description of at least one embodiment

[0011] In the example of Figure 1, the extinguishing device 1 is shown in a position corresponding to one of its possible installation methods. In the figure, however, the orientation of the extinguishing device and its mounting surface 6 has only been chosen to present the structure of the extinguishing device as clearly as possible, and the representation of the figure therefore does not aim to describe their actual orientation in the operating mode. The presentation of Figure 1

N 25 including some non-critical or irrelevant for the operation of the device

N parts, for example the cover part possibly related to the extinguishing device and one 3 wall part, have been omitted for clarity. Also, the attachment surface 6 is only partially shown in the figure 2 and dashed to show the continuity of its outer edges z outside the figure. so 30 [0012] The extinguishing device according to the example in question comprises the same

The extinguishing fluid source 2, the outlet 3 for supplying the extinguishing fluid from the extinguishing device, and the diagonal 4 arranged movably to the extinguishing device 1. Ky-

In the example, the six parts are arranged inside the frame 100, which defines the outer surfaces of the extinguishing device and consists of interconnected walls. In this case, the extinguishing device 1 is arranged to be installed at its intended use so that the bottom wall 101 of the frame is placed against the surface 6, and an opening 102 is arranged in the bottom wall, through which the surface 6 is in contact with the inside of the extinguishing device defined by the frame 100. The surface 6 in question is a preferably vertical surface included in the target of use of the extinguishing device, which delimits the space to which the extinguishing fluid of the extinguishing device is supplied.

[0013] The extinguishing device according to the example in Figure 1 further comprises a fastening arrangement 5 for attaching the extinguishing device 1 to the surface 6. The fastening arrangement can, for example, depending on the intended use of the extinguishing device, comprise, for example, one or more magnetic elements placed in the body of the extinguishing device 100, in which case the extinguishing device can be easily and quickly attached to a fer on a surface 6 made of a romagnetic substance. Arranged in this way, the fastening arrangement 5 is particularly suitable for use in connection with sea containers, for example. In other embodiments of the extinguishing device, the fixing arrangement 5 may instead of magnetic elements or in addition to them also include some other arrangement, for example the capabilities for fixing the extinguishing device 1 with separate fasteners, such as screws.

[0014] In the solution according to the example in Figure 1, the extinguishing device 1 is arranged in response to its triggering to move the piercer 4 in order to bring it into contact with the surface 6, and to rotate the piercer to create an opening in the surface 6. The opening in question is then intended to be created by the movement of the piercer 4 according to the description through the extinguishing fluid fed from the outlet 3. for what. The piercer 4 is thus advantageously designed to function like a drill bit. Extinguishing fluid can then be fed into the space defined by surface 6 through the created opening in order to extinguish or contain a strong temperature rise or fire observed in the space. More precisely sa-

N taken, in the example in question, the extinguishing device 1 is provided with a movable

S corresponding diagonal arm 7 for moving the diagonal 4, whereby the diagonal 4 extends

A from the diagonal arm. From the diagonal of the diagonal arm to the 4th end, there is an order-? ted articulation 9 to connect the diagonal arm 7 to the extinguishing device 1. In this case

S 30 — that is, the diagonal arm 7 is arranged to be moved to the extinguishing device by articulation

Through E 9, when the movement of the diagonal arm causes the movement of the diagonal 4 at the same time. La-

The diagonal 4 is then conveniently arranged close to the free end of the diagonal arm 7. 5 However, in some embodiments of the extinguishing device, the movement of the diagonal 4 can be

N also implemented in some other way than with the help of the diagonal arm 7, in which case the

The movement of the N 35 can be based, for example, on a force pushing towards the surface 6 in a straight line, such as a spring force or a pneumatic force.

[0015] The extinguishing device 1 according to the example in Figure 1 is arranged to supply extinguishing fluid to the extinguishing fluid source 2 in response to the triggering of the extinguishing fluid supply. The extinguishing fluid supply in question can then be arranged to be triggered as a result of one or more events detected by the extinguishing device 1, which can be internal or external events of the extinguishing device. In one favorable embodiment of the extinguishing device, the extinguishing device 1 is arranged to trigger the extinguishing fluid supply in response to the displacement of the diagonal arm 7 to a predetermined position. In this case, the predetermined position of the diagonal arm 7 favorably corresponds to the position near the range of motion of the other extreme end of the diagonal arm, which the diagonal arm reaches after piercing the surface 6 as a result of the extinguishing device 1 being fired. In other words, in this case, the extinguishing fluid supply is arranged to be triggered at the stage when an opening has been created in the surface 6 as a result of the rotation of the diagonal 4 against the surface, whereby the diagonal arm 7 moves as a result of the creation of the opening - above the predetermined limit towards the surface 6.

[0016] Said diagonal arm / predetermined position can be, for example, a certain angular position of the diagonal arm with respect to other parts of the extinguishing device 1, or for example a position determined by the point reached by the diagonal arm / free end. The extinguishing fluid supply can then be triggered by the trigger 103, which can be a mechanical trigger according to the example in Figure 1, or an electrical trigger. The electric current needed by the electric trigger can then come from, for example, a power source arranged in connection with the extinguishing device or a thermoelectric generator element. The electric current sources in question can also be included, for example, in a fire detector arranged in connection with the extinguishing device. When the trigger 103 is a mechanical trigger, it can be of FIG. 1

Corresponding to N examples, the diagonal arm 7 should be arranged near the diagonal arm 4, so that

S loi's extinguishing fluid supply can be triggered when the trigger comes into contact

A with the surface 6 or the bottom wall 101 of the extinguishing device. Alternatively, the triggering of the extinguishing fluid supply 7 can also be arranged to occur, e.g.

E found the space bounded by the surface based on the temperature information.

LO [0017] The example of Figure 2 shows the extinguishing device of Figure 1

S cross-section of the diagonal arm 7 of the end closer to the diagonal arm piercer 4

N eel. The structure of the diagonal arm 7 shown in Figure 2 corresponds to the same later

N 35 of the structure of the diagonal arm of the extinguishing device embodiments described in Figures 3 and 4. In the example in question, the outlet 3 is arranged on the diagonal arm 7, and the diagonal arm 4 extends from the diagonal arm 7 around the outlet 3 in its opening direction. In other words, the diagonal 4 according to the example in Figures 1 and 2 is arranged in a circular shape, whereby the diagonal defines the space in the middle where the outlet 3 opens. In this case, the diameter of the outer center 5 of the diagonal 4 determines the diameter of the opening made in the surface 6 at the same time. The arrangement in question enables the output 3 to be automatically placed in a favorable position in terms of feeding the extinguishing fluid through the opening created on the surface 6. More precisely, when the outlet 3 is arranged in a position and orientation corresponding to the location and orientation of the diagonal 4, the outlet 3 can be oriented without additional work steps towards the opening created by the diagonal 4 on the surface 6. In this case, the diagonal 4 can also act as an element controlling the supply of extinguishing fluid to the surface 6 through the opening created, whereby the walls extending from the diagonal arm 7 of the diagonal form a tubular structure between the outlet 3 and the opening.

[0018] In the example of Figures 1 and 2, the diagonal arm 7 is arranged in connection with the extinguishing fluid source 2 and comprises a channel 8 for transporting the extinguishing fluid from the extinguishing fluid source 2 to the outlet 3. More precisely, in the example in question, the diagonal arm is connected to the extinguishing fluid source via the joint 9, whereby the channel 8 extends through the joint. and from there — along the diagonal arm 7 to the outlet 3. The flow direction of the fluid inside the channel 8 is shown in figure 2 with visible arrow markings. In the example in question, the extinguishing fluid source comprises two pressure tanks 10 for storing the extinguishing fluid, so the extinguishing fluid they contain is advantageously pressurized gas, liquid or aerosol. In this case, the extinguishing fluid can be arranged to travel along the channel 8 from the extinguishing fluid source 2 to the outlet 3 by means of its own fluid pressure,

N in which case the extinguishing fluid supply can be controlled, for example, by the extinguishing fluid outlet

By means of a valve system connected to channel 2 or channel 8. Alternatively,

A extinguishing fluid can comprise, for example, the extinguishing fluid supply in connection with the triggering of where, as a result of the combustion reaction to be started, high-pressure gas or

S 30 aerosol forming fluid. In the arrangement according to the example in Figure 1, the

The reservoirs 10 are arranged on both sides of the diagonal arm 7, where they connect

O for articulation 9 symmetrically on its different sides. 5 [0019] In other embodiments of the extinguishing device, the extinguishing

N fluid source 2 can also be arranged differently from the example in Figure 1,

N 35, in which case it can comprise, for example, a space for storing extinguishing agent in solid form. = In such a case, the solid extinguishing agent in question can also be changed into a fluid form, for example as a result of the combustion reaction started when the extinguishing fluid supply is triggered, in order to create and feed the extinguishing fluid from the extinguishing fluid source 2. When the extinguishing fluid is stored directly in fluid form, the number of pressure tanks 10 close to the extinguishing fluid can also differ from the example in Figure 1 - from the chest, in which case there is at least one of them favorably. In applications where connecting the extinguishing device 1 to external systems is possible, the extinguishing fluid source 2 can also comprise a permanently arranged extinguishing fluid supply to the extinguishing device 1 from its outside.

[0020] In the example of figures 1 and 2, the rotational movement of the diagonal 4 is organized by means of the pneumatic device 13 arranged on the diagonal arm 7, which operates with fluid pressure. The pneumatic device can comprise, for example, a turbine according to the example in question, in which case the flow of the pressurized fluid arriving at the pneumatic device 13 causes the rotation of the turbine and at the same time the rotation of the diagonal 4 connected to the pneumatic device in relation to their common central axis. The extinguishing fluid of the extinguishing fluid source 2 can then be used as the operating fluid that transmits the driving force to the pneumatic device in question, for example, according to the example in Figures 1 and 2, in which case the extinguishing fluid source 2 functions as the operating fluid source at the same time. In this case, for the extinguishing fluid flowing to the diagonal 4, a second channel 15 is arranged in the diagonal arm 7 to receive and deliver the extinguishing fluid to the pneumatic device 13. In the example of Figure 2, the pneumatic device is also provided with a passageway at its central axis to allow the passage of the extinguishing fluid to outlet 3. The example of Figure 3, on the other hand, shows the extinguishing device another embodiment, in which the extinguishing device 1 comprises a separate — operating fluid source 12, in which case the rotation of the diagonal 4 takes place from the

N by means of the fluid pressure of the operating fluid obtained from the tablet source. In this case, the operating fluid can

S correspond in its composition, state and properties to extinguishing

A fluid or deviate from it, in which case, for example, the pressure of the operating fluid 7 arriving at the pneumatic device 13 can be arranged to be higher or lower than the pressure of the extinguishing fluid © 30.

E [0021] In the example of Figures 1 to 3, the movement of the diagonal arm 7 is arranged

O by means of the trigger spring 11 arranged in it. In this case, with the extinguishing device 1 5 ready to be triggered, the trigger spring 11 is advantageously arranged in an energized

to the N position, when the tripping of the extinguishing device causes the excitation to discharge

N 35 Senja thus moves the diagonal arm 7 by means of the spring force of the release spring 11. In this case, the spring force in question also produces a force pressing the punch 4 against the surface 6 after the free movement of the punch arm 7. The arrangement of the trigger spring 11 on the diagonal arm 7 means in this context that the trigger spring is arranged in contact with it in order to transmit the spring force to the diagonal arm.

The triggering of the trigger spring 11 can take place, for example, by means of a simple mechanical latch arrangement, whereby the release of the latch in connection with the triggering of the extinguishing device releases the movement of the trigger spring 11. The latch arrangement in question can then be arranged, for example, in connection with the joint 9, in which case, when the extinguishing device is ready for use, it prevents the jointed surfaces from moving relative to each other. In this case, the latch arrangement can be arranged to be released, for example, by means of the fluid pressure of the extinguishing or operating fluid when the extinguishing device is triggered.

[0022] The example of Figure 4 shows a third embodiment of the extinguishing device, which comprises an alternative arrangement to the example of Figures 1 to 3 for organizing the movement of the diagonal arm 7. In the example in question, the extinguishing device 1 comprises an operating fluid source 12, corresponding to the example in Figure 3, and a second pneumatic device 14 is arranged on the diagonal arm. In this case, the movement of the diagonal arm 7 takes place via the second pneumatic device in question by means of the fluid pressure of the operating fluid. The arrangement of the second pneumatic device 14 on the diagonal arm 7 means in this context that the second pneumatic device is arranged in contact with it in order to further transmit the force transmitted by the fluid pressure to the diagonal arm. The triggering of the second pneumatic device 14 can take place, for example, by controlling the flow of the operating fluid, in which case the pressure of the operating fluid automatically causes the movement of the diagonal arm 7 when the operating fluid arrives at the pneumatic device 14. The second pneumatic device 14 can, in some embodiments of the extinguishing device, be arranged to also act as an extinguishing fluid fluid

With the help of N dipressure, a separate operating fluid source is not needed.

S [0023] In the examples of both figures 3 and 4, the diagonal arm / is

A arranged in connection with the operating fluid source 12, and comprises a second channel 15 ? for receiving the operating fluid from the operating fluid source 12. The second ka-

The S 30 hub 15 is then arranged to transport the operating fluid from the operating fluid source 12

E for the pneumatic device or devices using it in each embodiment

O 13, 14. In the example of Figures 1 and 2, where the operating fluid is the extinguishing fluid of source 2, the second channel 15 is arranged correspondingly for extinguishing

N for receiving the extinguishing fluid from the extinguishing fluid source 2 and transporting it

N 35 for the pneumatic device 13. Both in the situation where the operating fluid source 12 is the extinguishing fluid source 2 and in the situation where the extinguishing device 1 comprises a separate operating fluid source 12, the supply of the operating fluid can be controlled, for example, by means of another valve system connected to the operating fluid source 12 or another channel 15, whereby the supply of the operating fluid can be arranged to occur, for example, as an immediate response to the triggering of the extinguishing device 1. In some embodiments of the extinguishing device, moving the diagonal arm 7 and rotating the diagonal 4 can also be arranged to occur at different times, for example as a timed response to the triggering of the extinguishing device 1. In the examples of Figures 1 to 4, the diagonal arm is additionally provided with an outlet 105 for removing the operating fluid bypassed by the pneumatic device 13 from the diagonal arm.

[0024] In the example of Figure 1, the extinguishing device 1 is additionally provided with a signal input 16 for receiving the triggering signal of the extinguishing device.

The signal input in question can comprise, for example, an electronic signal receiver for receiving a trigger signal transmitted wirelessly or by means of a data cable. In this case, the electric signal in question can originate, for example, directly from a fire detector arranged in the space bounded by the mounting surface 6 of the extinguishing device, or possibly from a control unit controlling a larger entity formed by numerous fire detectors and extinguishing devices 1. In some embodiments of the fire detector, something other than an electrical signal can also act as a trigger signal, for example a heat signal transmitted by a fire or filament. In some embodiments of the fire extinguisher, the fire detector 104 can also be arranged as a direct part of the structure of the fire extinguisher, as shown in the examples of Figures 3 and 4, in which case it can comprise, for example, a sensor detecting the rise in temperature of the surface 6.

[0025] In a method corresponding to the favorable way of using the extinguishing device according to the examples in Figures 1 to 4, the extinguishing device 1 is attached

N for surface 6. The surface 6 in question is then included in the use of the extinguishing device

A flat, preferably vertical surface that delimits the space subject to the supply of the extinguishing fluid of the extinguishing device. After this, depending on the situation? the type of trigger signal used in the operating situation and the location of the fire detector

From S 30, the extinguishing device can be immediately ready to receive the trip signal

E nail. Alternatively, the extinguishing device 1 can be connected to an electrical signal or

LO, for example for receiving a heat signal, for example a fire detector

To the S sim or the control unit, the wire intended for transmitting the signals in question

With the help of N tea. Regardless of the type of trigger signal, receiving it in the same

N 35 to the extinguishing device 1, for example, as a result of a fire detected in the space subject to the supply of extinguishing fluid, causes the diagonal 4 to move into contact with the surface 6. Simultaneously with the movement of the diagonal 4 in question, or alternatively after this, the rotation of the diagonal 4 begins to create an opening in the surface 6. When the opening in question has been created with the movement according to the description, extinguishing fluid is fed into it with the extinguishing device. More precisely, the extinguishing device 1 is then arranged to supply extinguishing fluid through the opening in question to the space to be supplied, in order to extinguish or limit the fire detected in that space. All method steps according to the description can be carried out with an extinguishing device using the structural components of the extinguishing device mentioned above.

[0026] In the extinguishing device according to the description, a pressurized fluid, such as NOVEC 1230 fire extinguishing agent, can be used as an extinguishing fluid. Alternatively, an extinguishing agent in solid or condensed form can be used in the extinguishing device, for example

Stat-X aerosol, whereby the extinguishing fluid required for the operation of the extinguishing device is obtained as a result of the combustion reaction of the extinguishing agent in question.

In those embodiments of the extinguishing device that comprise a separate operating fluid source for moving the parts of the extinguishing device according to the previous description, the operating fluid can be used as the operating fluid, in addition to the above-mentioned substances acting as extinguishing fluid, for example gases generated through the combustion reaction of various solid reactive substances, such as gunpowder or magnesium powder. In this case, for example, membrane foam liquid can also be used as extinguishing fluid.

It should be understood that the above explanation and related figures are only intended to illustrate the present invention. It will be apparent to those skilled in the art that the invention can be modified and

N also changes in other ways without deviating from the protection scope of the invention.
