Description

Exercise item for a fire extinguishing process

The invention relates to an exercise for a fire extinguishing operation, which can be set by the controllable supply of fuel and its ignition in flames. The exercise item can be used as part of a fire extinguisher.

Fire fighting trainers are in many variants in use. An example of such a trainer is described in EP 0 561 534 B1. It is assumed that a fuel supply, for example a gas of a gas cylinder. This gas cylinder is connected via a hose line to a burner unit, on which various exercise items can be arranged. The control of the gas supply takes place in the coach according to EP 0561 534 Bl means of a control panel.

For practice purposes, an object to be ignited, for example a waste paper basket, a vehicle tire, an electric generator or the like, is placed on the burner unit. The gas supplied to the burner unit is ignited. The rising from the burner unit flames set the practice counterpart in flames. This is then done according to predetermined rules, the extinction of the burning exercise object with an extinguisher.

The disadvantage is that the fire is introduced from the outside into the subject of the exercise. The object of the exercise therefore burns from the outside and not from the inside out. This can lead to unrealistic results and conclusions for the deletion process.

It is an object of the invention to provide an exercise item that corresponds in its outline shape of the real object, but which is only simulated.

The object is achieved according to the invention by the subject matter of claim 1 and the fire extinguisher according to claim 1, wherein in the region of its outer wall, which simulates him in its outer contour shape, leaking fuel is flammable, and in which the fuel to be ignited emitted by outlets is located in the area of the outer wall / exterior walls.

The advantage of this structure is that the flames are formed on the outer wall of the object of practice and from there, in particular from the interior, flood to the outside. This achieves a very realistic burning process. The object of the exercise is almost completely on fire. In a first embodiment of the invention, it is provided that the outer contour of the simulated training object is a hollow body and that in and / or within the outer wall of this hollow body, the outlets are provided for the escape of the fuel to be ignited.

In a second embodiment of the invention, it is provided that a basic component is provided as a supporting framework of the simulated, outer outline shaping, from the spaced apart lamellae whose outer edges outline the simulated exercise object, wherein the outlets for the outflow of the fuel to be ignited in Interiors are located between the free-ending slats.

Furthermore, fuel lines for the fuel supply are provided within the interiors, which are provided with the outlets, which allow the fuel to escape preferably along the outer wall of the base member.

This exercise simulates a real practice item; he is not flammable himself. With the basic component and the lamellae, almost all desired exercise objects can be formed.

The arrangement of the outlets is of particular importance. It is beneficial for a uniform firing process when the fuel is radiated directly onto the surface (s) of the base member and ignited. In order to achieve this it is provided according to a further embodiment of the invention that the fuel lines, e.g. in the interior of the body, are arranged at a distance close to the outer wall of the base member and that the outlets are directed to the outer wall of the base member.

According to a further embodiment of the invention, it is provided that the fuel lines are inherently stiff in order to stabilize the basic component. It can be omitted in this case special supports. The fuel lines thus take over the fuel supply and the stabilization of the subject of the exercise. This is especially important if the exercise item has a special height.

According to a further embodiment of the invention it is provided that the subject of the exercise is releasably secured to the pedestal; he can then easily be exchanged for other exercises. The training object can also be used as an attachment module independently of its own pedestal. According to a further embodiment of the invention it is provided that the base member is a metal plate, are fixed to the metallic lamellae. Such a basic component is easy to manufacture. Of course, it can also consist of a hollow body or two profiled plates, which in turn can be used for fuel line.

The slats are inserted in slots and preferably also welded. With suitable production technology can be dispensed with the slots and welded directly.

According to a further embodiment of the invention, it is provided that the base member and the slats of refractory materials, such as ceramic or stainless steel, exist.

According to a further embodiment of the invention, it is provided that the object of the exercise in its simplest form is a straw bale in its simulated outlines. Such a straw bale burns quickly and must be extinguished quickly, with particular attention to fire nests.

According to a further embodiment of the invention, it is provided that the exercise item has the shape of a human in its simulated outlines.

According to a further embodiment of the invention, it is provided that the exercise item has the shape of a wheel in its simulated outlines.

These embodiments serve as examples. Other forms simulatable by the same principle can be used with equal advantage.

According to a further embodiment of the invention, it is provided that an ignition device is arranged on the pedestal. In a variant, it is also possible that the ignition device is arranged on the object of practice.

According to a further embodiment of the invention, it is provided that the fuel lines are divided into line areas and that the line areas from which the fuel in an exercise for the purpose of ignition should flow, lead separately fuel or can be released for filling with fuel. This has the advantage that you can practice the deletion of certain areas of a practice item particularly. In another embodiment of the invention, it is provided that the fuel lines are divided into line areas, and that their outlets are adjustable so that they are always open only in the line areas from which the fuel is to flow in an exercise. Here, therefore, the fuel lines can all be filled and only the open outlets determine the inflamed line area.

According to a further embodiment of the invention, it is provided that the subject of the exercise can be moved during a deletion exercise. So a blotter can also practice erasing a runaway practice item.

According to a further embodiment of the invention, it is provided that a plurality of training objects are arranged on a pedestal.

According to a further embodiment of the invention it is provided that the hollow body serves as a fuel line to the outlets. It can be dispensed with in this case to concrete fuel lines in the hollow body. For the attachment of the outlets there is greater freedom.

As the fuel, any type of flammable compound, such as e.g. Hydrocarbons, used as far as they are transportable in lines. In addition to gases in particular, sprayable liquid fuels, such as diesel or gasoline, can also be used, for example.

A fire-fighting trainer always consists of parts or aggregates arranged as desired, with which a fire can be created and deleted for practice purposes. So there must be a fuel source and an exercise item. The fuel source is connected via fuel lines with some kind of burner / ignition unit. In this a fire is created, with which the practice object is set on fire. Control units are used to control the fuel flow.

The invention is concerned with a construction of exercise objects that burn brightly, are not unusable when burning and need no special burner unit; It uses all previously used parts and units of fire fighting trainers as known advance and assumes that in addition to separate burner units these parts or aggregates are also used for burning exercise materials according to the invention. The burner units conventional units have risen in the exercise or merged with him to form a unit.

Show it:

Fig. Ia, Fig. Ib and Fig. Ic in side view, front view and plan view of a pedestal of a fire extinguisher on which a training object is arranged, which mimics a straw bale. The imitated straw bale consists of a basic component and arranged on this lamellae, which release between them combustion chambers and form an overall outline in the form of a straw bale,

2 shows a detail of the basic component of the straw bale according to FIG. 1 with fuel lines extending laterally from both sides thereof, which have fuel outlets towards the basic component, FIG.

4 shows an exercise article with the shape of a standing human being, wherein a human figure arranged on a pedestal consists of a basic component and lamellae projecting from it, FIG.

Fig. 5 shows the basic component of the exercise article according to Figure 4 without pedestal. The basic component is viewed from the front, and at the front of the designated slats are attached,

6 shows a detail of the basic component with a fuel line arranged in front of it, which has fuel outlets to the outer wall of the basic component,

FIG. 7 shows the pedestal base arranged on a carriage in order in particular to be able to burn the simulated human figure,

FIG. 8 shows a simulated exercise object in the form of a vehicle tire which is arranged on a pedestal and consists of a basic component in the form of a rim ring and lamellae protruding from it; FIG. 9 is an illustration of the assignment of fuel line and rim ring,

Fig. 10 shows another Ausfülirungsform the subject of the exercise with a hollow body in the form of the simulated practice object and provided at it outlets for the escape of the fuel to be ignited.

FIGS. 1a, 1b and 1c show a simple demonstration model of such a subject G in the form of a straw bale 1a. This simulated straw bale Ia has a plate-like basic component 2 as the supporting framework. Slats 3 protrude perpendicularly from it. This can be seen particularly well from FIG. 1c. The lamellae 3 are preferably inserted into slots 4 (as in FIG. 5) and welded to the base component 2. The insertion in slots 4 can be dispensed with a suitable manufacturing method. The slats 3 have in their entirety an outer contour 3 a, which corresponds to the outer contour of a natural straw bale.

Both the basic component 2 used and the lamellae 3 are made of metal. If there are other materials with the appropriate properties, such as non-flammability, safe connectivity, for example, weldability, so these are of course applicable. It is especially to think of ceramics.

On the base member 2 5 fuel lines 6 are provided on both surfaces, which extend from a pedestal 7 in the subject of exercise G, in the straw bales Ia. There will be cases where a fuel line 6 on a surface 5 is sufficient. In this case, 5 fuel lines 6 are provided by way of example on both surfaces. The fuel lines 6 are connected in a manner not described in detail with a fuel source, not shown.

FIG. 1 b shows that the fuel lines 6 are arranged diverging from the pedestal 7. Also, the ignition unit 8 is shown, from which emerge a spark or a pilot flame and ignite the leaked straw in the straw bale I gas.

Fig. 2 shows an enlarged detail of the use of the fuel lines 6, which can set the straw bale Ia by the controllable supply of fuel and its ignition in flames. The fuel lines 6 are provided for this purpose with respect to the outer wall 5 of the base member 2 with outlets 9. As shown in FIG. 3 based on a shows even further magnification, the fuel passes through the outlets 9 in the direction of the outer wall 5 from the fuel line 6 and, as the arrows 10 show, along the outer wall 5 distributed. The spaces between the basic component 2 and the slats 3 are referred to as internal spaces 24, where the flames arise. From the transitions 27, where the free ends of the blades 3 end outside, the flames flood visible to the outside.

The fuel lines 6 are made of metal. Other materials are of course applicable, as long as they withstand the heat. The fuel lines 6 can also have a different cross section than the drawn square cross section. The fuel lines 6 enhance the stability of the base member 2 when they are rigid.

The fuel lines 6 need not rest on the base member 2; For example, they can also extend through holes in the slats 3. It is not mandatory to direct the outlets 9 to the basic component 2. The flame formation also works with other blow-out directions. Furthermore, it is not necessary that the fuel lines 6 are stiff; Flexible hoses can also be used.

FIG. 4 shows a further variant of the subject matter G. On the pedestal 7, the shape Ib of an upright person is attached. This human form Ib is again constructed as in Fig. 1 of straw bales Ia; it has as a supporting frame a basic component 20 with an outer contour 33a, which indicates a human shape. The base member 20 is inserted into the pedestal 7 and welded thereto. If the exercise item G is used as an attachment module, then the attachment to a pedestal 7 is eliminated.

As shown in FIG. 5, the basic component 20, as well as the basic component 2 of the straw bale 1 a according to FIGS. 1 a to 1 c have slots 4. These are not shown in FIGS. 1 a to 1 c. In the slots 4, the fins 33 are inserted. It can be seen from FIG. 4 that the lamellae 33 discharge differently or have different outer contours, in such a way that a human figure can also be seen in the side contour 33b.

The fins 33 are, as can be seen in FIG. 4, inserted one above the other from the front side 21 of the shape and once from the rear side 22 of the shape into the base component 20. From Fig. 5 it can be seen that one above the other is always an inserted Slat 33 and then slots 4 can be seen again. Where you see the slots 4, the fins 33 are inserted at the back 22. The fins 33 thus have larger distances and the flames can escape well to the outside. The slats can also be arranged circumferentially. The spaces between the base member 20 and the fins 33 are also referred to here as interiors 24, where the flames arise. Via the transitions 27, where the lamellae 33 terminate freely on the outside, the flames visibly emerge to the outside.

On the base member 20, fuel pipes 26a, 26b and 26c are arranged. Also in this subject G / Ib they serve the stabilization. The fuel lines 26a and 26b, into which the fuel from an unspecified fuel source is introduced, lead along the legs 27 from the pedestal 7 up to a control unit 26d. This control unit 26d resists the temperatures occurring.

Optionally, the fuel line 26c leading upwards from the control unit 26d may be additionally supplied with fuel. If appropriate, however, this fuel line 26c can also discharge the fuel via its outlets 29 alone. This applies to the case that the outlets 29 can be opened and closed, for example, by means of a control instruction.

In general, the fuel lines can be divided into line regions 26a, 26b, 26c. The fuel line sections 26a, 26b, 26c, from which the fuel is to flow during an exercise for the purpose of ignition, can then be released separately for filling with fuel.

It is also to be considered to make the outlets 29 adjustable so that they are always open only in the fuel line areas 26a, 26b, 26c from which the fuel is to flow in an exercise.

The outlets 29 of the fuel lines 26a, 26b and 26c can be seen from Fig. 6. Through this to the outer wall 25 of the base member 20 facing outlets 29, the fuel gas to the base member 20 escape. It is deflected on the outer wall 25 in the direction of the arrows 10. The flames thus form along the outer wall 25 and migrate between the fins 33 to the outside. The orientation of the outlets 29 to the base member 20 is not mandatory. Another outlet direction of the outlets 29 is also possible. Fig. 7 shows a carriage track 32, along the pedestal 7, which is movable by means of a carriage 34. The method can be done on sliding surfaces or by means of wheels. It is also conceivable to pull the exercise object Ib alone through the terrain. The method of the pedestal 7 along the carriage track 32 is provided for practice purposes. Normally a burning person would run away. Here the extinguisher can practice what to do when the subject is in motion during the erase process.

FIG. 8 shows another exercise object G, namely a vehicle wheel Ic. The load-bearing framework of the simulated vehicle wheel Ic is the base component 40, which is a type of rim ring 40, on which, as described for the other exercise items G, fins 43 are fixed. The slats 43 extend in the drawing at an oblique angle to the rim ring 40. A vertical course can also be selected. The fins 43 have in the entirety of their outer edges an outer contour 43a. To the rim ring 40 extends an annular fuel line 46 which is provided with outlets 49. An orientation of the outlets 49 on the rim ring 40 is preferred. The fuel line 46 is connected in a known manner to a fuel source. The fuel supply is also controlled in a known manner and will not be described in more detail.

FIG. 9 shows in an enlarged view an outlet 49 with the flow arrows 10 of the flowing fuel deflected on the outer wall 45 of the rim ring 40. The spaces between the base member 40 and the fins 43 are referred to as interiors 24, where the flames arise. At the transitions 27, where the fins 43 terminate freely on the outside, the flames visibly protrude outwards.

It can be arranged on a pedestal 7 more exercises G objects.

The basic components 2, 20, 40 may be made of a flat sheet metal. Likewise, it is also possible to use double-walled hollow parts or to use specially provided for their stiffening ribs or the like. It will always be paid to the most appropriate for the individual case of a subject of practice suitable design.

According to the description of the individual subjects of practice G / Ia, Ib, Ic, it can be seen that a basic principle extends through all the subjects of practice G / Ia, Ib, Ic: On a basic component 2, 20, 40, lamellae 3, 33, 43 are fixed, which with their outer contours 3a, 33a ₅ 43a simulate the real exercise object G. This has the advantage that not all exercises must be used in realistic construction. A further uniform feature is that the fuel burns on the outer walls 5, 25, 45 of the exercise objects G / Ia, Ib, Ic itself and not outside of the exercise objects G / Ia, Ib, Ic. The burning process is very realistic.

Another variant of the exercise object G / 51 shown in FIG. 10 assumes that the basic component of the exercise object 51 consists of a hollow body 56 which simulates a human shape on the outer wall 61 with its contour formation 52. The hollow body 56 is composed for example of profile shells. The simulated practice object 51 stands on a pedestal 7. However, it can also be used without pedestal 7, for example as an add-on module. Outlets 54 or windows 54 are distributed over the outer wall 61 of the exercise object 51. From these occurs initially not flamed fuel. By means of a Zündaggregates 8, for example in the pedestal 7, the fuel is ignited on the outer wall 61. The flames simulate a full-fledged exercise object.

The fuel supply to the hollow body 56 via fuel lines 57. Within the direction indicated by the line 58 risers can be seen, the fuel lines 57.

The fuel supply can be wholly or partially via the hollow body 56, which then acts as a fuel line. There is then greater freedom in the arrangement of the passages 54

Forming as a human form is only an example. In all the subjects of the invention, the base member 2, 20, 40, be a hollow body, either with only outlets 54 on the outer wall 5, 25, 45, 61 or with outer fuel lines 6, 16, 46 and fins 3.33, 43 works.

Also, a flaming of the fuel inside the Hohlköpers 56 is conceivable. In this case, the flames would exit the outlets 54 and creep on the outer wall would set this outer wall 61 on fire.
