Description

Extinguishing arrangement and method for extinguishing or cooling a parked or parked vehicle

The invention relates to an extinguishing arrangement, which can also be referred to as an extinguishing agent retention arrangement, particularly outdoors, in buildings, multi-storey car parks, underground car parks, garages, tunnels, under bridges or underpasses, ships, ferries, trains or on parking areas or other areas or in other areas, for example parked or abandoned or evacuated vehicles or vehicles involved in an accident, in particular electric vehicles, with an extinguishing arrangement or extinguishing agent retention arrangement surrounding the vehicle at least laterally. For the sake of simplicity, only extinguishing arrangement is used below for extinguishing arrangement or extinguishing agent retention arrangement.

The invention also includes a method for extinguishing or cooling a parked or parked vehicle.

The invention is intended in particular to ensure that when extinguishing fires on and/or in vehicles, the respective vehicle or at least the source of the fire is surrounded as completely as possible by the extinguishing agent and, if necessary, the vehicle or the respective energy storage device is or can be flooded with the extinguishing agent and in doing so the extinguishing agent is restrained from uncontrolled spread.

At present, electromobility is increasing rapidly, leading to a change in transportation. New problems arise due to the increased occurrence of parked or parked electric vehicles, particularly in underground car parks or also on other surfaces or in other areas. The safety specialists have great safety concerns when there is a battery fire in an electric vehicle. A possible solution for extinguishing or cooling a burning electric vehicle is to store the electric vehicle in a container filled with a suitable extinguishing agent for more than 48 hours.

In the event of an electric vehicle fire in an underground car park or in buildings such as tunnels, under bridges or underpasses, especially without a pre-installed extinguishing system, new solutions are urgently needed. It is not the rescue workers and the fire brigade possible to intervene if a battery fire occurs. The reason is that when the battery burns, a high temperature is generated, which endangers the building fabric and static weaknesses can occur. The reinforcing steel in the concrete support structure of the underground car park can fail. It is currently forbidden for rescue workers and the fire brigade to intervene in these parking garages and underground car parks in the event of fire. In extreme cases, a building can collapse.

DE 102019 003 289 A1 discloses an extinguishing device for extinguishing a motor vehicle fire, the extinguishing device comprising a device base for parking a motor vehicle and a device wall which is connected to the device base. When the device wall is in use, it forms a container together with the device base, the container interior of which is designed to accommodate the motor vehicle and to accommodate extinguishing medium for extinguishing the motor vehicle fire, the device wall being expandable from a non-usable state to a used state by introducing the extinguishing medium. Furthermore, the extinguishing device comprises a nozzle element which is arranged on the device wall and is designed to guide the extinguishing medium from the interior of the wall into the interior of the container.

JPH0679010A discloses different barriers for vehicles parked in a parking facility. For example, roller shutters are provided that seal off the burning vehicle in the event of a fire or enclose the parking area of the vehicle. Likewise, a shutter can be lowered or a sideways sliding curtain can be provided to enclose the parking area of the vehicle.

WO2018222046A1 discloses a device for extinguishing fires in energy storage devices of electrically powered vehicles, whereby walls are placed around the vehicle to form a basin that can be filled with water to cool down the temperature in the batteries, the thermal runaway to stop and extinguish the fire. The device also keeps the waste extinguishing agent containing toxic substances and electricity safely away from rescue workers during firefighting and provides the opportunity to subsequently contain the waste extinguishing agent for proper disposal. Known from WO 2020253 909 A1 is a fitting for fighting fires and/or for cooling burning objects, which is pushed or arranged under the vehicle or electric vehicle and sprinkles water on the respective vehicle from below, thus extinguishing a burning battery or a battery that is on fire may be advised to cool.

DE 202017 002 156 U1 discloses a surface sprinkler pipe for fire fighting.

DE 202020 103 375 Ul a discharge container into which the vehicle to be discharged is to be pulled. A disadvantage is the complex construction, which, if necessary, is also difficult to transport to the fire site.

The object of the present invention is to provide an extinguishing arrangement for a vehicle that, in the event of a fire or if necessary, surrounds the respective vehicle or electric vehicle in such a way that extinguishing agents are used directly and only in a limited space, while the vehicle and thus the source of the fire are used as required completely surrounded or flooded with extinguishing agent and also prevent any or uncontrolled outflow of the extinguishing agent and at the same time hardly restrict parking.

The object of the invention is achieved in that an extinguishing arrangement is created for stationary, for example parked or parked vehicles, in particular for electric vehicles, with the respective vehicle standing or being able to be parked on a parking space, with a wall arrangement around the vehicle on the parking space at least in certain areas or sections can be erected, which are designed to surround or enclose the vehicle at least on the sides, i.e. at least in front, behind, right and left in relation to the vehicle, in order to accommodate an extinguishing agent at least in the enclosed area or in the area surrounding the vehicle and/or and to surround and/or flood the vehicle with the extinguishing agent at least in certain areas. The wall arrangement is designed to enclose the vehicle at least laterally, starting from a ready position in a required position, the wall arrangement according to the invention in the ready position being at least partially or partially sunk into the parking space or laterally below the parking space is arranged and can be pushed, pulled, rolled out and/or folded out vertically or upwards into the required position by means of an adjusting device or by filling from the storage area or to the side of the storage area.

Advantageously, the wall arrangement is designed to enclose the vehicle at least laterally, starting from a ready position in a required position.

This can be done or triggered manually or automatically by means of an adjusting device. Areas can be constructively provided and designed accordingly. A movement path can also be determined at least approximately on the basis of the ready position and the required position, so that it is possible for the wall arrangement to be moved easily from the ready position to the required position without the movement of the wall arrangement being disturbed by the vehicle or the wall arrangement collides with the vehicle or with parts of the vehicle when moving. In addition, it is possible to specify when and how a vehicle can or should be parked on the parking area.

The flexible wall arrangement, for example, is stored in the ready position, for example in or on the edge of the storage area or in a box arranged accordingly in or under the storage area, rolled up or folded up and, if necessary, is, for example, by a corresponding positioning device on the side of the storage area to fulfill its function for example brought into the required position.

At least one linear drive, a toothed rack or a spindle drive, a hydraulic cylinder, a pneumatic cylinder, a cable pull, a chain, a telescopic rod or a movable scissor mechanism and combinations can be considered as the actuating device. Likewise, the adjusting device can be used, for example, as or with a preloaded spring.

Advantageously, the corresponding wall arrangement can be moved manually or automatically by means of the actuating device or can only be triggered if the wall arrangement independently encloses or can enclose the vehicle. Automatic triggering and movement is particularly advantageous for unattended areas. The positioning device, which is coupled to a sensor system, allows the wall arrangement to be moved quickly from the ready position to the required position if required.

The source of the fire or potential source of the fire and the outflow of the extinguishing agent can advantageously be prevented by rapid, preferably sensor-controlled and thus automatic or automatable erection of the wall arrangement enclosing the vehicle. In this way, the fire can be contained quickly, the spread of the fire to other vehicles or the surrounding area or a building as well as the influence on the building and the surrounding area can be prevented or at least reduced. In addition, damage to them can be prevented or at least minimized.

Alternatively, as a mobile variant, the wall arrangement comprises at least two modules, with the modules each having a floor profile that rests directly on the storage area and the at least two modules extending upwards from the floor profile like a wall and being pre-assembled, with the at least two modules moving from the ready position laterally around the Vehicle can be moved or lifted into the required position on the parking area and can be deducted and connected to one another on the parking area. In the standby position, for example, the at least two modules that have been prepared or set up in advance at the place of use are away from or at a safe distance from the vehicle, while in the required position, for example, the at least two modules are arranged around the vehicle.

The floor profile can be designed in several parts and can be assembled.

A module of the mobile variant can have a foldable or swiveling wall section. Vehicles can also be moved in or out without having to dismantle or remove the wall arrangement as a mobile variant.

In this way, the extinguishing arrangement can be used around a vehicle at almost any accessible location, even outside of buildings, with little effort. Due to a multi-part design in modules, the modules can be easily arranged laterally around the vehicle without having to lift them over the vehicle, for example. The vehicle can be a small vehicle, such as a single-track vehicle, or a commercial vehicle, such as a truck. The frame and the wall arrangement and the connections are to be designed accordingly. For example, two U-shaped modules or two or four L-shaped modules or mixed forms are possible in use, or corresponding U-shaped and/or L-shaped modules are provided or prepared, which when arranged result in an extinguishing arrangement enclosing the respective vehicle.

This reliably encloses the vehicle at the side. Extinguishing agent cannot or only slightly escape. In this case, the wall arrangement is connected or at least in contact with the storage area by at least touching or bumping into each other. This also includes fastening or anchoring or a non-positive or positive connection of the wall arrangement to or with the storage area.

Storage space is understood to mean all surfaces or areas with a floor, such as not exclusively outdoors, in buildings, multi-storey car parks, underground garages, garages, tunnels, under bridges or underpasses, in or on ships,

Ferries, trains or in parking lots or other areas or other areas in or on which vehicles are or may be parked or left parked. For example, these may be vehicles that have not been parked, abandoned, broken down, had an accident, or have been evacuated.

In the event of a fire or if necessary, an at least partially movable wall arrangement surrounding at least the side of the vehicle can be placed. The wall arrangement can be formed in one piece or from a plurality of sections or modules that can therefore be moved or moved separately. The wall arrangement or the sections or modules can thus be moved around the vehicle, which has been driven onto the parking area or parked or left standing for any reason, this area or place or space being understood as a parking area, in the event of a fire or in case of need or be driven. In the event of a fire or if necessary, the vehicle is enclosed at least laterally up to a floor, for example that of the parking area, by the wall arrangement, so that the extinguishing agent cannot flow out. The parking area is thus the reference area or permissible parking area for the vehicle, for the use of the respective wall arrangement and/or in order not to impair the use of the respective wall arrangement. Smoke development or heat development or a gas detection indicating an impending or developing fire is understood as a case of need.

Provision can be made for the wall arrangement to form an enclosure, ie it is also closed on the side above the vehicle. Likewise, with an appropriate parking space, the wall arrangement as a housing can enclose the vehicle on all sides.

Depending on the wall arrangement, it is advantageous that there is a seal to the storage area. Depending on the wall arrangement and configuration or structural design, a seal or sealing effect can be formed directly or indirectly during use.

The wall arrangement surrounding the vehicle on the side prevents the extinguishing agent used from running off to the side in the event of a fire or if necessary. Accordingly, the extinguishing agent is held back by the wall arrangement, so that the vehicle remains surrounded by the extinguishing agent as completely as possible and, if necessary, can also be flooded with the extinguishing agent.

The wall arrangement designed to be movable at least in sections makes it possible to provide the entire wall arrangement or the separately movable sections in such a way that the vehicle can access the parking area and, if necessary, comfortably get in and out. For example, three sections can be permanently installed as wall sections of the wall arrangement of the extinguishing arrangement and a movable section according to the invention can be arranged as a wall section in the area of the driveway/exit. The wall arrangement or the separately moveable sections can thus change from a position allowing vehicle access to a position where there is a need to retain the extinguishing agent.

However, it can also be provided that the wall arrangement is sunk in the parking area circumferentially or continuously laterally, i.e. at least at the front, rear, right and left in relation to the vehicle, or is arranged laterally below the parking area and vertically from the parking area or to the side of the parking area or pushed up, pulled, rolled out and/or folded out Due to the retention of the extinguishing agent that is possible with the device according to the invention, the fire can be fought effectively and locally, in particular the vehicle or the source of the fire can be quickly surrounded by the extinguishing agent. This also very effectively counteracts the spread of the fire and reduces damage to nearby vehicles or the respective building or structure or the environment or the fire brigade. At the same time, the suppressed outflow saves on extinguishing agents and the respective surroundings and the environment as well as the fire brigade are less affected and the cleaning effort is reduced.

In order to achieve the object of the invention, the invention also provides a method for extinguishing or cooling a parked or parked vehicle, in particular an electric vehicle, with the respective vehicle being parked on a parking space.

The method can advantageously be carried out using the extinguishing arrangement according to the invention.

In the process, upon detection of a fire or a

Exceeding the temperature or smoke development or a gas detection indicating an imminent or developing fire around the vehicle standing on the parking area erected or positioned a wall arrangement at least in some areas and enclosed the vehicle at least laterally. The area enclosed by the wall arrangement is flooded with an extinguishing agent and the extinguishing agent at least partially surrounds the vehicle and/or floods the vehicle, flooding, the wall arrangement being moved at least in sections from a ready position to a required position and the vehicle being enclosed at least laterally.

According to the invention, the wall arrangement is pushed, pulled, rolled out and/or folded out vertically or upwards from the ready position at least in certain areas or sections by means of an adjusting device or by filling from the storage area or from the side below the storage area. Alternatively, according to the invention, at least two modules of the wall arrangement as a mobile variant are moved or lifted from the standby position onto the parking area from different directions on or around the vehicle into the required position, thereby enclosing the vehicle at the side, and are placed on the parking area and connected to one another.

With regard to electric vehicles in particular, all battery-operated vehicles or hybrid battery-operated vehicles are understood. This includes all single-track, dual-track and three-track battery-powered or hybrid battery-powered vehicles. For example, these include electric cars, electric commercial vehicles, electric trucks, electric bicycles, electric motorcycles, electric scooters, electric mopeds and electric tricycles.

The extinguishing arrangement must be dimensioned and/or designed according to the vehicle type or size. Depending on the need, the different versions can be scaled and adapted to the specific vehicle.

Although the focus is on electric vehicles, this does not exclude all other vehicles or vehicles powered in other ways.

The extinguishing arrangement is also suitable for the other vehicles with a different or alternative energy source or an energy carrier for the drive or for vehicles driven in a different way. This also includes vehicles with as yet unknown drives or energy sources.

In simplified terms, vehicles are therefore spoken of in a generalized manner.

Suitable extinguishing agents and/or coolants are water, foam and/or sand or other well-distributing extinguishing agents. Furthermore, additives are conceivable which qualify unsuitable extinguishing agents so that they can be used afterwards. An additive is, for example, a wetting agent that is added to the extinguishing water and this is then suitable for extinguishing fires from or on lithium-ion batteries or other electrical energy sources or accumulators. Likewise, different extinguishing agents can be combined if the situation or the environment requires or allows it. To put it simply, different variants or combinations are recorded under extinguishing agents, one To extinguish the fire or to cool the fire or the electric vehicle and, if necessary, the surrounding area.

Advantageous developments of the invention are specified in the dependent claims.

The wall arrangement is advantageously in one part or in several parts and comprises wall sections or a housing or a curtain or a hose or a foil bag or a foil, so that extinguishing arrangements for different locations,

Storage areas or static requirements, constructive features or different fire classes can be created. The construction can also be adapted to the needs and resilience of the wall arrangement. Likewise, different versions of the wall arrangement can be combined or a version made up of several parts. The design of several parts can be isolated or put together directly or via connecting elements.

For example, wall sections can be combined to form a multi-part wall arrangement and connected in a flexible, rigid, fixed or detachable manner.

In an advantageous development, wall sections of the wall arrangement can be coupled or connected via profiles in which the wall sections are guided or can be guided or arranged. The transition between the respective wall section and the respective profile also forms a seal. The profiles can be arranged in corners of a square or a polygon. These profiles extend at least into or onto the shelf or are arranged in or on the shelf.

In an advantageous embodiment of the invention, it is provided that an additional wall arrangement, at least in certain areas or sections, for example as individual or connected wall sections, from above, i.e. from or from a ceiling or holder or a frame arranged above the storage area, vertically downwards or downwards or can be pulled out or rolled down, dropped down, folded out and/or folded out down to or into the floor. A wall arrangement, for example made of flexible material, is rolled up in the ready position, for example on the ceiling above the storage area in a box arranged there, folded or collapsed or folded up and, if necessary, is moved to the side of the storage area by a corresponding adjusting device Fulfilling its function in the required position by being guided, for example, up to the wall arrangement coming from or from the side of the storage area or up to the floor or advantageously for sealing in a groove arranged in the floor.

According to a further advantageous development, the wall arrangement is designed to be extendable or rollable, foldable and/or foldable, at least in certain areas or sections, for example as individual or connected wall sections, laterally or horizontally around the vehicle. Accordingly, the vertically arranged wall arrangement can be moved laterally or horizontally by means of an adjusting device in such a way that the wall arrangement is guided around the vehicle down to the floor and the flow of the extinguishing agent is thus advantageously prevented.

According to a further advantageous development, the wall arrangement can be pulled out, rolled out, unfolded and/or folded out at least in certain areas or sections above the vehicle, so that the vehicle can be closed at the top and the fire can be spatially limited.

These aforementioned further developments for wall arrangements can be combined as desired, as a result of which the respective vehicles can be enclosed more reliably and the extinguishing agent can also be held back more reliably. For example, a wall arrangement can be provided from above and from below, which meet or overlap away from the ceiling and the shelf.

Thus, these aforementioned developments for wall arrangements can be designed in combination as a combined, one-piece or complex wall arrangement, which in turn encloses the respective vehicle accordingly. Thus, channel-like, tube-like or hose-like wall arrangements come into consideration.

For multi-part combined wall arrangements, seals or connecting elements are used at the joints or connection points or overlapping points of the respective wall arrangements for reliable and automatic sealing and connection. Thus, one-way elements come into consideration as seals or connecting elements, which may be opened in a destructive manner to recover the vehicle after extinguishing or fighting the fire, as well if necessary, the wall arrangement has to be replaced or repaired due to the fire.

According to an advantageous embodiment of the invention, the wall arrangement is rigid or rigid or foldable or foldable. This includes the fact that it comprises individual rigid or stiff wall sections which are connected to one another in a hinged or foldable manner, for example by means of hinges or via flexible transitions. Seals are advantageously present at the joints and towards the floor.

For example, metal plates or plates made of suitable plastics or flat or plate-like composite materials come into consideration as a rigid or stiff wall arrangement, which in addition to mechanical resistance also have thermal resistance.

However, the wall arrangement can also be flexible or foldable or coilable. The wall arrangement can be single-walled or at least double-walled or have at least one internal hollow chamber. A single wall arrangement allows for a simple and lightweight construction. Due to the double-walled wall arrangement, the stability of the wall arrangement and, depending on the design of the wall arrangement, the tightness to one another and to the storage area can be improved or increased by means of a filling. Different fillings can be provided by inner chambers. For example, extinguishing agents, water, sand and/or compressed air or another gas or an extinguishing gas can be considered as filling.

This double-walled design of the wall elements, which is realized with flexible wall material, is advantageously designed with internal hollow chambers that are connected to one another. Water or an extinguishing agent can be poured into the hollow chambers between the two outer walls of the double-walled, flexible wall material. The weight of these tube-like or sack-like wall arrangement elements is thus pulled downwards and pressed against or into the ground, thus promoting sealing to the ground.

For example, foils or tarpaulins or flat composite materials can be considered as flexible wall material, which, in addition to mechanical resistance or strength, also have thermal resistance. In addition, the films or Tarpaulins or composite materials, for example, have coatings or integral or superimposed reinforcements, such as metal mesh, which favor mechanical resistance as well as thermal resistance.

Alternatively and additionally, the wall arrangement has support structures, reinforcements or stiffeners or coatings, as a result of which the stability and strength are increased. The flexible wall material can thus advantageously be made of a reinforced composite material or reinforcements/stiffeners can be arranged on the outside of the flexible wall material. The reinforcement can be designed, for example, as a fabric material or fiber material or as metal wires or metal meshes integrated into the wall material in the direction of the greatest stress.

Support structures, for example in the form of struts or rods, and reinforcements, for example in the form of lattice structures or load-bearing structures, can also be provided in or on the wall arrangement.

A separate reinforcement or reinforcement, which is arranged outside of the sealing flexible wall material and absorbs the compressive forces, can also be advantageously used here.

Alternatively and additionally, there are support structures, reinforcements or stiffeners that are independent of the wall arrangement and that indirectly support and/or stabilize the wall arrangement separately and/or outside of the flexible wall material that seals, for example, and absorb pressure forces.

Due to the flexibility of the wall material, a good adaptation to the floor and a corresponding sealing to the floor is possible. A rubberized or silicone-coated fabric, for example, or a mineral fiber fabric or a reinforced foil, for example metal fabric-reinforced, can be used as the material here. In addition to the preferred mechanical resistance, fabric and film are preferably also fireproof or at least flame-retardant or highly heat-resistant. Depending on the application, the mechanical resistance or the flame-retardant or highly heat-resistant property can prevail. In addition, flexible wall material can be easily folded or rolled up or collapsed or folded and thus stowed away in a very space-saving manner in the ready position.

According to an advantageous embodiment of the invention, it is provided that the shelf has a groove-like depression, a pedestal and/or at least in some areas a double floor, with the upward pull-out, roll-out, fold-out and/or fold-out wall arrangement is provided and/or the wall arrangement that can be pulled out, roll-out, fold-out and/or fold-out or drop-out can be fastened, fixed or guided, for example from above or to the side or horizontally. By accommodating the wall arrangement in the required position in the floor, this advantageous embodiment enables anchoring or guidance and, thanks to the additional form fit, better sealing of the wall arrangement with respect to the floor. Furthermore, the flexibly designed wall arrangement can advantageously be stowed in the ready position below the parking area of the vehicle, for example under the pedestal or in the false floor or in the groove-like depression.

Furthermore, it is advantageously provided that a ramp leading to the storage area is present, it being possible for the ramp to be independent of the storage area or part of the wall arrangement. A ramp is necessary in particular when the parking area of the vehicle is designed as a pedestal, ie elevated, or when a groove has to be driven over in order to be able to drive onto the parking area. The ramp can be designed in the manner of a flap and thus advantageously at the same time as a wall section of the wall arrangement. Driving onto or over the wall arrangement can advantageously be prevented in order to avoid damage to the wall arrangement.

Because the wall arrangement or the respective module or floor profile can be sealed off or is sealed off from the storage area or is connected to the storage area, retention of the extinguishing agent is promoted. This also reduces the need for extinguishing agents. Depending on the seal, the associated friction also promotes the positional stability of the wall arrangement. Because the wall arrangement or the respective module or the respective floor profile has a seal or is designed as a gravity seal or as a seal, the design and structural complexity of the wall arrangement and also of the storage area can be reduced. In addition, depending on the wall element, the sealing effect can be adjusted by filling for gravity sealing.

By filling the wall arrangement as a gravity seal or as a seal with an extinguishing agent and/or with a gas or gas mixture, the constructional and structural complexity of the wall arrangement can be reduced, at least with regard to adequate sealing, since additional structural or structural seals can or these can only be used at least in reduced form. In addition, depending on the environmental conditions, special static features can be addressed by using extinguishing agents and a gas or gas mixture arranged in sections or areas. In addition to air, extinguishing gases or other suitable, preferably non-combustible or fire-retardant gases or gas mixtures can also be used as the gas or gas mixture.

Advantageously, there is at least one sensor and/or at least one parking aid and/or at least one overflow arrangement or filling level monitor, so that the vehicle is parked accordingly by means of the at least one sensor and/or the parking aid and this can also be monitored in order to check the function of the extinguishing arrangement and so as not to impede the movement of the wall assembly or to collide with the wall assembly. Furthermore, the extinguishing agent consumption and/or loss of extinguishing agent can be recorded and/or recognized with the overflow arrangement or fill level control.

Furthermore, sensors can be provided which detect a fire or an excess of temperature or the development of smoke or carry out a gas detection indicative of overheating or combustion.

In this way, sensors from the respective building technology can be used or integrated and, if necessary, supplemented with additional sensors. In this way, existing detection gaps can be closed for monitoring of an imminent or incipient fire. Since the double-walled wall arrangement or the internal hollow chambers or the floor profile can be filled with the extinguishing agent or water, the design and structural complexity of the wall arrangement can be reduced, at least with regard to stabilization. Additional structural or constructive stabilization can be reduced or dispensed with.

By having openings in the area enclosed by the wall arrangement in the double-walled wall arrangement or in the internal hollow chambers or in the floor profile, an equalization or distribution of extinguishing agent between the wall arrangement and the area enclosed by the wall arrangement is promoted by both the wall arrangement upon reaching a certain filling level at which the openings are arranged, extinguishing agent enters the enclosed area or, conversely, extinguishing agent from the enclosed area passes through the openings into the wall arrangement and thus the wall arrangement continues to fill depending on the filling level in the enclosed area.

Furthermore, it is advantageously provided that the wall arrangement has at least one extinguishing agent inlet and/or at least one nozzle pointing towards the vehicle or at least one extinguishing agent outlet. Extinguishing agent, for example in the form of a hydro-shield for extinguishing or cooling, can be sprayed and/or flooding can begin when moving from the standby position to the required position. In addition, protected by the wall arrangement, the extinguishing hoses can be connected and flooding can be carried out more directly and at least with less loss.

By having an extinguishing agent supply, the extinguishing arrangement can be filled immediately or directly, or extinguishing or cooling can begin. In this way, hoses or the extinguishing agent inlet can be connected or laid with little effort and with a short length.

While the at least two modules of the wall arrangement are moved or lifted sideways around the vehicle as a mobile variant and placed on the parking area and connected to one another, the nozzles can already be used to spray extinguishing agent in the form of a hydroshield for extinguishing or cooling. Since the respective modules of the wall arrangement can be folded or pivoted in several parts or assembled together, the modules can be stowed and transported to save space when not in use and set up in advance at the place of use. Accordingly, the respective modules of the wall arrangement can be unfolded or pivoted apart for use and folded or pivoted or disassembled or disassembled again into a more compact or space-saving form after use. In addition, the modules can be adapted and combined to suit different vehicles or vehicle sizes.

By having rollers or wheels on the modules of the wall arrangement, for example, which can be adjusted in position or height, the modules can be moved easily and purposefully to the vehicle and enclose and align it on the side and then lower it, for example by raising the wheels or rollers or be pivoted away, whereby the modules of the wall assembly lower and sit on a surface as a shelf or rest or stand.

According to an advantageous embodiment of the invention, the at least two modules can be moved laterally around the vehicle, at least in certain areas or sections, manually or by means of a drive. This improves handling and personal protection.

According to an advantageous development of the method, the area enclosed by the wall arrangement is flooded at least from the parking area at least up to the upper edge of the vehicle wheels or up to the upper edge of the electronics or the batteries or accumulators or at least up to the source of the fire. In this way, electric fires can be counteracted effectively, purposefully and as needed, especially in electric vehicles.

According to an advantageous development of the method, the wall arrangement can be pulled out, unrolled, unfolded and/or dropped vertically downwards or down or down to or into the storage area, at least in certain areas or in sections, from or from a ceiling or from a frame or a holder. or unfolded, the respective vehicle can be enclosed from the ceiling to the parking area. According to a further advantageous development of the method, an additional wall arrangement is pulled, folded out, unrolled and/or unfolded at least in certain areas or sections laterally or horizontally around and/or over the vehicle, allowing the respective vehicle to be viewed from the side and from above enclose on all sides.

Since the at least two modules of the wall arrangement are moved or moved at least in regions or sections with one drive each, the process and arrangement is simplified and personal protection is improved.

According to an advantageous embodiment of the invention it is provided that after moving the wall arrangement into the required position, the space between a double-walled wall arrangement or internal hollow chambers or a gravity seal is filled or flooded with the extinguishing agent or with water. The sealing of the wall arrangement towards the floor is favored by the filling and the required stability of the wall arrangement is improved if necessary.

By introducing or spraying extinguishing agents while the wall arrangement is being moved at least in sections from a standby position to a required position and the vehicle is surrounded at least on the side, the vehicle can be cooled and, if necessary, a fire can be prevented or, in the event of a fire, the fire and its surroundings can be cooled.

Furthermore, extinguishing agent can already be sprayed and the environment can be cooled while moving the respective modules of the wall arrangement, which is advantageous for personal protection and firefighting.

Figures 1a and 1b show an extinguishing arrangement according to the invention, which comprises a circular, generally movable wall arrangement 3 made of flexible, double-walled wall material 3a, which is arranged folded up in the ready position in a groove-like recess 6 let into the storage area 2. Cable winches 10 are arranged as adjusting device 10 on a ceiling 13 or a frame (not shown) above the installation area 2 and are connected to the double-walled, flexible, movable wall arrangement 3 by means of cables 10a. The wall arrangement 3 can be pulled upwards via the cable winches 10 as the adjusting device 10 and the cables 10a.

FIG. 1b shows a perspective view of the wall arrangement 3 made of flexible, double-walled wall material 3a, which has been pulled up into the required position. The raised, double-walled, flexible wall material 3a thus forms a kind of foil bag and thus a double-walled, flexible, movable wall arrangement 3. The Intermediate space 5 within the double-walled, flexible, movable wall arrangement 3a, 3a is filled with water 4 or extinguishing agent 4 if necessary.

Due to the weight resulting from the filling, the double-walled, flexible, movable wall arrangement 3 is pressed against the bottom of the groove-like depression 6 and against the radially lateral inner walls or inner sides in the groove-like depression 6 or on the shelf 2, so that the seal 11 to the Storage space 2 and / or the groove-like recess 6 takes place. This double-walled, flexible, movable wall arrangement 3 is connected to one another all the way around or is made all the way around as a double-walled wall material 3a, for example as a foil bag, so that the movable wall arrangement 3 can be filled with water 4 or another extinguishing agent 4 .

In an improved embodiment, the double-walled, flexible, movable wall arrangement 3 can have openings (not shown) at a certain height on the side facing the storage area 2, so that from this level the extinguishing agent 3 can flow out of the intermediate space 5 into the space enclosed by the movable wall arrangement 3a Space with the vehicle 1 can flow.

The double-walled, flexible, movable wall arrangement 3 is pulled upwards or vertically to the intended height by means of the adjusting device 10 designed as a cable winch 10 and the cables 10a. The intermediate space 5 within the double-walled, flexible, movable wall arrangement 3 is then filled with water 4 or extinguishing agent 4 and the space within the double-walled, flexible, movable wall arrangement 3 is then filled with extinguishing agent 4 .

By arranging the double-walled, flexible, movable wall arrangement 3 in the groove-like depression 6, as shown in Figure 2, a contact pressure 23 is exerted on the inner walls or inner sides of the groove-like depression 6 in the required position due to the filling, and thus an improved seal 11 for groove-like recess 6 and the shelf 2 realized.

In Figure 3, a movable wall arrangement 3 made of flexible wall material 3a, such as a film 3a, is shown as a extinguishing arrangement Ready position in a double floor 24 folded under the shelf 2 housed. In the storage area 2 there is a circumferential groove-like depression 6 through which the wall arrangement 3 can be pushed from the ready position into the required position and encloses the vehicle 1 laterally.

The movable and peripheral wall arrangement 3 made of flexible wall material 3a as a foil bag wall can be filled with extinguishing agent 4 and seals off the storage area 2 as a gravity seal 11 . Accordingly, the wall arrangement 3 can be filled and thus raised to such an extent that extinguishing agent 4 for fire-fighting can be filled within the flexible wall material 3a at a suitable height. Inside and outside of the wall assembly 3, the shelf 2 is at the same level.

In Figure 4a to 4c an extinguishing arrangement with a movable wall arrangement 3 made of flexible wall material 3a, such as a foil 3a, is shown in the required position provides, kept folded next to or around the designed as a pedestal 16 shelf 2 in the ready position.

Ramps 15 leading to the pedestal 16 are provided for entering or driving in or parking or parking. A groove-like recess 6 is formed between the platform 16 and the ramp 15, in which the folded film 3ad wall arrangement 3 is arranged. This compact design of the wall arrangement 3 is therefore also well suited as a retrofit. The movable wall arrangement 3 made of flexible wall material 3a can be moved upward into the required position by means of a scissor mechanism 19 and/or by means of a telescopic hydraulic cylinder 20, as shown in FIGS. 4a and 4c. The movable and peripheral wall arrangement 3 made of flexible wall material 3a as a foil bag wall can accordingly be raised to such an extent that extinguishing agent 4 for firefighting can be filled within the flexible wall material 3a at a suitable height.

Alternatively, the movable wall arrangement 3 can also be double-walled and thus fillable.

In the figures 5a to 5d an extinguishing arrangement is shown, in which the wall arrangement 3 is let into the storage area 2 in a groove-like depression 6. Here, as shown in Figure 5d, four telescopic rods 20 are used as the adjusting device 10 distributed over the corners as a lifting system with hydraulic or pneumatic cylinders or with a spindle drive. When retracted, the telescopic rods 20 are sunk into the storage area 2 . The flexible wall material 3a of the wall arrangement 3 comprises a plastic film which, as shown in FIG. However, it can also lie folded up in the groove-like depression 6 on the bottom thereof. As shown in FIG. 5c, the four supports are extended via the lifting system until the end position is reached. This pulls the flexible wall material 3a of the wall arrangement 3 upwards into the required position and thus tightens it. Inside the plastic film, as shown schematically in FIG. 5a, there is a steel grid as a support structure 30, which gives the wall the necessary strength. When the end position or required position is reached, the area enclosed by the wall arrangement 3 is filled with extinguishing agent 4 up to the maximum required height. The fire protection system regulates the extinguishing agent level until an authorized person assesses the situation and initiates further steps.

FIGS. 6a and 6b show a movable wall arrangement 3 made of flexible wall material 3a, the flexible wall material 3a being double-walled. The wall arrangement 3 is arranged around the shelf 2 here. The parking area 2 forms a pedestal 16, with ramps 15 being available for driving on.

The wall arrangement 3 can be folded out or pushed out upwards with an internal positioning device (not shown). The wall arrangement 3 has a seal 11 for the storage area 2 . In addition, reinforcements (not shown) can be provided which straighten up when unfolded or pushed out.

The wall arrangement 3 can also be pushed up into the required position by filling an internal hollow chamber (not shown) with water 4 or extinguishing agent 4 or another filling material, as shown in FIG. 6b. A gravity seal 11 to the floor 12 is realized by the filling weight.

FIG. 7 shows an extinguishing arrangement according to the invention, which comprises a circular, generally movable wall arrangement 3 made of flexible wall material 3a which, in the ready position, is embedded in a shelf 2 annular groove 6 (not shown) is arranged folded. Distributed in the storage area 2 outside of the wall arrangement 3 as a positioning device 10 are telescopic rods 20 with hydraulic or pneumatic cylinders or with a spindle drive as a lifting system. The wall arrangement 3 can be pulled upwards into the required position via the lifting system.

A seal 11 is present between the wall arrangement 3 and the groove-like recess 6 or the shelf 2 .

Figure 8 shows an extinguishing arrangement according to the invention as a sectional view in which the wall arrangement 3 comprises four modules 12, for example as a mobile variant, which are each arranged from the ready position to a square in the required position and can be connected and/or connected at the corners and enclose the vehicle 1, The modules 12 each have a floor profile 17 resting on the storage area 2 as a ballast trough 18 which is connected to the wall arrangement 3 or merges into it, the ballast trough 18 being arranged within the area enclosed by the wall arrangement 3 . Seals 11 (not shown) are present between the modules 12 at the corners. The ballast trough 18 is advantageously flooded first and after it overflows or parallel thereto the area with the vehicle l. The ballast pan 18 forms a gravity seal 11. In addition, a seal 11 can also be provided on its underside. The four modules 12 extend like a wall from the floor profile 17 upwards and are preassembled, the at least two modules 12 being able to be moved or lifted laterally around the vehicle 1 and placed on the parking area 2 and connected to one another.

Another extinguishing arrangement according to the invention as a mobile variant for parked vehicles 1, in particular for electric vehicles, and details thereof are shown in FIGS. 9 to 13.

A wall arrangement 3 can be erected around the respective vehicle 1 parked on a parking area 2, which is designed to surround or enclose the vehicle 1 at least laterally in such a way that at least in the enclosed area, an extinguishing agent 4 can be accommodated and/or retained and the vehicle 1 to be surrounded and/or flooded with the extinguishing agent 4 at least in certain areas. The wall assembly 3 is formed, starting from a ready position in a Demand position to enclose the vehicle 1 at least laterally. The wall arrangement 3 as a mobile variant comprises two U-shaped modules 12 which each have a floor profile 17 resting on the storage area 2 . As shown in FIGS. 9 and 10, the two modules 12 extend upwards like a wall from the floor profile 17 and are preassembled.

As an alternative to the U-shape, the modules 12 can also be L-shaped, which, when assembled or arranged, also result in a U-shape or an essentially rectangular shape, which forms the extinguishing arrangement that encloses the respective vehicle 1 .

The floor profile 17 is oriented outwards, outside the area enclosed by the wall arrangement 3 . As shown in FIG. 11, the bottom profile 17 is made up of several parts and has a continuous seal 11 for each module 12 . In the connecting area 22 or contact area 22 of the two modules 12 arranged one on top of the other, the seal 11 is designed longer or protruding. The seals 11 can be arranged next to one another in an overlapping manner. For a secure position and sealing effect, the bottom profile 17 has a connecting profile 27 with a guide 25 for the seals 11. The connecting profile 27 of the bottom profile 17 with the guide 25 is shown in FIG. 12a and viewed from below in FIG. 12b.

The two U-shaped modules 12 can be lifted laterally from the ready position, for example in the direction of the arrow around the vehicle 1 into the required position, and can be placed on the parking area 2 and connected to one another. Accordingly, the modules 12 can be removed from the vehicle 1 again in the opposite direction of the arrow.

Accordingly, two or four L-shaped modules 12 can also be lifted or moved or moved laterally around the vehicle 1 from the ready position into the required position and can be set down on the parking area 2 and connected to one another.

Likewise, mixed forms of U-shaped and L-shaped modules 12 can form the extinguishing arrangement. FIG. 10 shows a single module 12 of the wall arrangement 3 according to FIG. At the edges in the connection area 22 or contact area 22 to a module 12 that can be arranged thereon, there is a seal 11 at least in the area of the wall arrangement 3 that extends upward like a wall.

The wall arrangement 3 has a flexible wall material 3a reinforced with a metal mesh (not shown), which has additional reinforcements and reinforcements (not shown) particularly at the upper edge and in the corner areas.

The modules 12 can be reliably connected via fastening means 26 or locking devices 26, as shown for example in FIGS. A further connection is realized via the connecting profile 27 of the base profile 17 .

Additional fasteners 26 or latches 26 may also be present. For this purpose, the wall arrangement 3 preferably has further reinforcements (not shown) in this area.

The module 12 shown in FIG. 13 can have a foldable or pivotable wall section 28 in a wall arrangement 3 as a mobile variant. In the closed state, the pivotable wall section 28 is sealed off from the stationary wall arrangement 3 by means of a seal 11 .

In the figures 14 to 19 another extinguishing arrangement according to the invention is shown as a mobile variant for parked vehicles 1, in particular for electric vehicles, as well as details.

In the case of the extinguishing arrangement according to the invention shown in FIG. 14 as a mobile variant for parked vehicles 1, a wall arrangement 3 can be erected around the respective vehicle 1 parked on a parking space 2. Vehicle 1 is surrounded or enclosed laterally in such a way that an extinguishing agent 4 is received and/or retained in the enclosed area formed thereby and the vehicle 1 is at least partially surrounded and/or flooded with the extinguishing agent 4 . The wall arrangement 3 can be moved around the vehicle 1 from a ready position away from the vehicle 1 into a required position and thus encloses the vehicle 1 laterally, ie from the front, rear right and left. The wall assembly 3 as a mobile variant includes two modules 12 in the specific example, each one on the Storage area 2 overlying bottom profile 17 with a supporting hollow profile 29 arranged thereon and seal 11 arranged on the bottom profile 17 . The floor profile 17, the hollow profile 29 and the seal 11 are arranged within the enclosed area or on the side of the wall arrangement 3 which faces the vehicle 1 .

The wall arrangement 3 of the respective modules 12 is designed in several parts and is foldable.

In the specific example, there are six wall sections 28 per module 12 , which are connected to one another via fastening means 26 and locks 26 . The fasteners 26 and latches 26 are designed to pivot accordingly.

The number of modules 12 can vary. In this way, four or six modules 12 can also be arranged and connected accordingly. Likewise, the modules 12 can include a different number of wall sections 28 .

The wall arrangement 3 or the wall sections 28 of the modules 12 extend like a wall upwards from the floor profile 17 and are preassembled. In the specific example, sheet metal is used as the material for the floor profiles 17 and wall sections 28 . In the area of vertical outer edges of the wall sections 28 31 profiles are present as reinforcements. From a ready position, the modules 12 , which have already been folded out and locked for this purpose, can be moved laterally around the vehicle 1 into the required position with the wheels 21 also folded out or lowered for this purpose. By folding up or folding in or lifting the wheels 21, the respective modules 12 can be placed on the storage area 2 and connected to one another. It is provided that either the modules 12 are connected to one another before the respective modules 12 are set down on the storage area 2 or that the respective modules 12 are first set down on the storage area 2 and then the modules 12 are connected to one another.

FIG. 14 shows that the wall arrangement is completely assembled in the required position, is set down on the parking area 2 and encloses a vehicle 1 .

Furthermore, an extinguishing agent feed is provided, which is guided to two extinguishing agent inlets 13 . An extinguishing agent inlet 13 is directly connected to an extinguishing agent outlet 14 which faces the vehicle 1 or the area enclosed by the wall arrangement 3 . A further extinguishing agent inlet 13 is guided to a nozzle 23 . By means of the nozzle 23, a hydro-shield can be set up when moving or lifting, which already cools the fire and thus already protects the environment and the emergency services.

The two modules 12 can be moved laterally from the ready position, for example in the arrow direction shown, around the vehicle 1 into the required position and can be set down on the parking area 2 and connected to one another. Accordingly, the modules 12 can be removed or driven away from the vehicle 1 in the opposite direction of the arrow.

Deviating from and supplementing the explanations for FIG. 14, FIG. 15 shows a single module 12 of a wall arrangement 3, in which the wheels 21 are folded out or lowered. Seals 11 are provided on the edges or the reinforcements 31 of the individual adjacent wall sections 28 and on the connection area 22 or contact area 22 to a further module 12 .

FIG. 16 shows a sectional view of the floor profile 17 with a supporting hollow profile 29 arranged thereon and the seal 11 arranged on the floor profile 17 . The floor profile 17 and the seal 11 lie on the shelf 2 . The wall section 28 of the wall arrangement 3 or of the module 12 extends upwards from the floor profile 17 like a wall. The hollow profile 29 can be filled with the extinguishing agent 4 or another ballast as part of the bottom profile 17 . Likewise, the seal 11 can be filled or pressurized from the inside.

FIGS. 17 and 18 show folded-up modules 12 of the wall arrangement 3, as can be accommodated, for example, in emergency services vehicles.

The individual wall sections 28 of the wall arrangement 3 or of the module 12 with the floor profiles 17 and the seals 11 on the edges or the reinforcements 31 are connected via pivotable fastening means 26 or locking means 26, so that the wall sections 28 can be folded out and in on the one hand and fixed on the other are.

FIG. 19 shows the plan view of an L-shaped module 12 comprising three wall sections 28 of the wall arrangement 3. A wall section 28 has two Extinguishing agent inlets 13, which are guided to an extinguishing agent outlet 14 and a nozzle 23 accordingly. Fastening means 26 or locking means 26 and seals 11 are present in the corner area of the corner area and in the area of the connecting area 22 of the two wall sections 28 arranged alongside one another. Likewise, 3 seals 11 are present at the connection areas 22 to further adjacent modules 12 with wall sections 28 of the wall arrangement.

When using this module 12, for example, four modules 12 are required to set up a wall arrangement 3 of the extinguishing arrangement enclosing the respective vehicle 1, which can be moved or lifted laterally around the vehicle 1 and placed on the parking area 2 and can be connected to one another.

The wheels 21 or also rollers 21 can also have a drive for moving the modules 12 .

All features of the designs shown and described can be combined with one another as far as possible or expedient.

In particular, the or all flexible wall arrangement 3 or the wall sections 28 can be single-walled or double-walled and thus fillable.

The flexible wall arrangement 3 or the wall sections 28 or the flexible wall material 3a can be reinforced with fabric, steel wire or steel girders, whereby these reinforcement structures can be integrated into the flexible wall material 3a or arranged as support structures 30 outside of the flexible wall material 3a.

Scissor lattices can each be arranged on the outside or inside as reinforcement structures.

The movement or movement of the movable wall arrangement 3 or the wall sections 28 can be carried out not only by adjusting devices 10 of different designs, but also by hand or by means of adjusting devices of different designs.

The movement of the wall arrangement 3 or the wall sections 28 and the filling with extinguishing agent 4 or water 4 can be automated by detecting the need using suitable sensors.

Parking aids, for example by means of light barriers, can be provided to ensure that the vehicle 1 does not protrude beyond the parking area 2 and thus the any necessary movement of the wall arrangement 3 or the wall sections 28 is not disturbed.

The filling level of the water 4 or extinguishing agent 4 can be regulated with a float/level sensor.

The method according to the invention for extinguishing or cooling a stationary vehicle 1, in particular an electric vehicle, provides that the respective vehicle 1 is standing on a parking space 2 and upon detection of a fire or exceeding the temperature or smoke development or gas detection around the vehicle standing on the parking space 2 1 a wall arrangement 3 is erected or positioned at least in certain areas. The vehicle 1 is enclosed at least laterally and the area enclosed by the wall arrangement 3 is flooded with an extinguishing agent 4 . The extinguishing agent 4 surrounds the vehicle 1 at least in certain areas and/or it is flooded. To enclose the vehicle 1, the wall arrangement 3 is moved at least in sections from a ready position to a required position and the vehicle 1 is enclosed at least laterally.

In one embodiment of the method, the wall arrangement 3 is pushed, pulled, rolled out, vertically or upwards, at least in certain areas or sections, by means of an adjusting device 10 or by filling it with an extinguishing agent 4 from the standby position out of the storage area 2 or from the side below the storage area 2, into the required position /or unfolded.

In another embodiment, at least two modules 12 of the wall arrangement 3 as a mobile variant 4 of the extinguishing arrangement are moved or lifted from the standby position laterally around the vehicle 1 into the required position and placed on the parking area 2 and connected to one another.

Extinguishing agent 4 can advantageously be introduced or sprayed while the wall arrangement 3 is being moved at least in sections from the ready position to the required position and the vehicle 1 is being enclosed at least laterally. In particular with the mobile variant, this can reduce the risk to rescue workers. In both versions, an additional floor, for example a plastic sheet or floor film, is not required.

Furthermore, the area enclosed by the wall arrangement 3 is flooded at least from the storage area 2, for example up to the upper edge of the vehicle wheels or up to the upper edge of the electronics or the batteries or accumulators or at least up to the seat of the fire.

After moving the wall arrangement 3 into the required position, the intermediate space 5 of a double-walled wall arrangement 3 or internal hollow chambers or a gravity seal 11 can be filled or flooded with the extinguishing agent 4 or with water 4, after which the enclosed area is then flooded or with a delay.

Furthermore, an additional wall arrangement 3 (not shown) can be provided which, at least in certain areas or in sections, falls vertically downwards or downwards or downwards to or into the storage area 2 from or out of a ceiling or from a frame or a bracket, extended, can be unrolled, unfolded and/or unfolded.

In addition or as an alternative, this additional wall arrangement 3 can also be pulled, folded out, unrolled and/or unfolded laterally or horizontally around the vehicle 1 .

Likewise, additionally or alternatively, the additional wall arrangement 3 can be pulled out, unrolled, unfolded and/or unfolded over the vehicle 1 .
