Description

[0001] Fire barrier and ice element, provision arrangement and method for erecting the fire barrier

[0002] Description

[0003] The invention relates to a fire barrier for the on-demand and mobile protection of an object, such as a piece of land, agricultural or forestry land, a building, and / or an infrastructure facility, against exposure to heat and / or flames during a fire event, according to the preamble of claim 1, as well as a stackable ice element for erecting the fire barrier, a provision arrangement, and a method for providing solid ice elements for erecting the fire barrier. For this purpose, the fire barrier comprises a barrier structure that extends substantially lengthwise and vertically, forming a physical obstacle to the fire event. The barrier structure comprises an ice wall constructed from several solid ice elements. This allows the fire barrier to generate a cooling effect by absorbing thermal energy.The meltwater generated as a result of heat absorption, which is released from the fire barrier, can also irrigate the surrounding subsoil, which in turn can contribute to extinguishing or stopping a fire front.

[0004] A mobile fire barrier for forest fires is known from CN216934496U. This barrier consists of a panel made of fire-resistant material mounted on a rotating chassis. As long as the panel's long sides are held parallel to the ground, it can be moved by rolling using the chassis. By rotating the panel by 90°, however, the panel can be placed securely on the ground with its short side.

[0005] The disadvantage of the mobile fire barrier is that it is a purely passive barrier, which can only temporarily contain a fire in front of the object to be protected. Furthermore, the arrangement of several such fire barriers in a row, especially on uneven ground, leads to larger gaps and gaps, which also significantly impairs the passive effect of such a fire barrier.

[0006] The object of the invention is to avoid the aforementioned disadvantages in a generic fire protection barrier and to achieve an active extinguishing effect.

[0007] This problem is solved by a fire protection barrier having the features of claim 1. The ice wall is at least partially formed by an ice wall that can be constructed from stackable, solid ice elements. This allows the ice wall to be constructed in any length and height and without significant gaps forming between the stacked or masonry ice elements.

[0008] Compared to other extinguishing methods, such as spraying or dropping extinguishing water, the water used to construct the fire barrier is significantly more effective due to the lower evaporation rate. The fire barrier constructed from solid ice elements can stop or contain a fire front, effectively protecting people, animals, landscapes, buildings, and infrastructure from the fire. Furthermore, the ice wall and its cooling effect can reduce smoke formation and block the spread of smoke, particularly at ground level, to prevent or mitigate health risks to people and animals, as well as property damage to buildings and infrastructure.By effectively isolating the area from the fire, the need for evacuations can be reduced or at least panic-like behavior and resulting traffic congestion can be avoided. By improving the protection of facilities against destruction and reducing the need for evacuations and evacuations, such as hospitals and nursing homes, people can be protected and high costs avoided.

[0009] Preferably, the stackable ice elements are uniformly preformed to enable easy storage and handling, as well as quick and uniform erection of the ice wall or ice walls. In a particularly preferred embodiment, the fire barrier comprises two ice walls spaced apart from each other to form an escape corridor for people or vehicles. This allows protected passage of people and / or vehicles, such as emergency vehicles, within a fire zone by means of the fire barrier.

[0010] Alternatively or additionally, the solid ice elements are at least partially formed by pourable ice elements, which enables particularly simple and rapid production of the solid ice elements required for the ice wall. The solid ice elements can thus be stored as bulk material and transported in large quantities using excavators or wheel loaders, and then deposited in the area of ​​the fire barrier.

[0011] It is particularly advantageous if the pourable ice elements are contained in pumpable crushed ice. This allows the ice elements to be continuously transported to construct the ice wall, for example, via pump lines. This allows for a particularly fast and mobile construction of the ice wall, similar to a rampart.

[0012] In a particularly preferred embodiment of the fire protection barrier, the pourable ice elements are piled up on or between the stackable ice elements to enable compact application of the pourable ice elements in large quantities. In this way, erected ice walls can be additionally cooled or reinforced. Furthermore, the construction and filling of two- or multi-layer ice barriers is possible in this way. Alternatively or additionally, an escape corridor can be created in this way, for example in an existing fire area. For this purpose, the floor can, for example, be covered with pourable ice elements to create an escape route, which is then protected at both edges by the construction of an ice wall.Furthermore, the above-mentioned object is achieved by an ice element for erecting a fire protection barrier in one of the embodiments described above, wherein the ice element is essentially formed by a stackable, cuboid-shaped ice block. As a result, the ice element can be stacked together with other uniform ice elements in a particularly stable manner in order to be able to erect a particularly stable ice wall in the manner of a wall, the height and length of which can also be adapted to the respective object to be protected and the respective fire event. The cuboid-shaped ice block has a form-fitting contour on a first side and a form-fitting counter-contour on a second side facing away from the first side, which is at least partially complementary to the form-fitting contour.This allows the ice element to be positively connected to a positively locking counter-contour or a positively locking contour of a neighboring ice block by means of the positive-locking contour or the positive-locking counter-contour. The positive connection can be created either at a vertical transition or at a horizontal transition between two neighboring ice blocks. This allows a stable and largely gap-free connection between the individual ice blocks to be created both vertically and horizontally along the ice wall.

[0013] It is advantageous if the ice block has vertically shaped connecting elements on its upper side, which complement the mating connecting elements on its underside. This creates an interlocking or positive connection between stacked ice blocks, which can increase the stability and tightness of the ice wall. This positive connection prevents the ice blocks from shifting, slipping, or becoming detached from one another. Furthermore, the dense construction of the ice wall can effectively block the spread of smoke, particularly at ground level.

[0014] It is advantageous if the plug-in means have at least one stud protruding from the cuboid ice block and the counter-plug-in means have at least one stud receptacle incorporated into the cuboid ice block, so that a form-fitting connection which is easy to produce and effective horizontally on all sides can be provided.

[0015] Alternatively or additionally, the plug-in means on the upper side comprise at least one through-bolt extending over the entire horizontal extent of the cuboid ice block, and the counter-plug-in means on the underside comprise at least one through-groove extending over the entire horizontal extent of the cuboid ice block. This allows similarly shaped ice elements to be stacked particularly quickly to form the ice wall, forming a positive connection.

[0016] It is advantageous to have two through-grooves on the underside, the width and spacing of which are adapted to the forklift carriage. This not only creates a positive connection, but also allows the forklift to grip the through-grooves securely. This makes the ice elements, even those with larger dimensions and greater weight, easy to handle when erecting the ice wall or the masonry ice wall.

[0017] It is also advantageous if a gripping aid is molded into each ice block to enable the ice blocks to be safely grasped, lifted and transported by hand or using a lifting device.

[0018] For this purpose, the gripping aid preferably has two access openings that extend horizontally into the cuboid ice block on two opposite sides. This design, integrated into the ice block, allows for a particularly simple and stable design of the gripping aid. Furthermore, this design does not impede the tight fit of two adjacent ice elements.

[0019] In a particularly preferred embodiment, the ice block contains an additional extinguishing agent that can be released upon melting to generate an additional extinguishing effect. Advantageously, the additional extinguishing agent is contained in at least one cavity of the ice block. This cavity within the ice block allows a relatively large amount of the additional extinguishing agent to be accommodated and safely stored together with the remaining ice block for an extended period of time.

[0020] It is advantageous if the additional extinguishing agent is formed by CO2, which escapes when the ice block melts, displaces the oxygen in the vicinity of the ice wall and thus suffocates or pushes it back at least in part.

[0021] Furthermore, the above-mentioned object is achieved by a storage arrangement for the provision of solid ice elements for erecting a fire protection barrier in one of the above-mentioned embodiments, wherein the storage arrangement comprises an ice production plant for producing the solid ice elements and a passively or actively cooled ice storage facility for long-term storage of the produced ice elements, such as, for example, at a building, an industrial or infrastructure facility, a forest, an enclosure or stable, and / or an agricultural facility. In this way, the ice elements required for erecting the ice wall can be produced and stored in advance in geographical proximity to the respective object to be protected in order to be able to erect an ice wall protecting the object in a minimal amount of time in the event of a fire.Depending on the type of water available at the location, drinking water, service water, wastewater, salt water, or fresh water can be used. By providing such a fire barrier, damage to buildings can be prevented, which in turn can reduce insurance costs. For this purpose, it might also be conceivable, for example, to establish a kind of interest group made up of property owners and / or insurance companies to implement and, in particular, finance the provision of the fire barrier. The ice storage facility has a temperature-insulated enclosure to enable the pre-produced ice elements to be stored for extended periods with negligible melting losses, even in the absence of, or only minimal, active cooling of the ice storage facility.It is advantageous if the ice storage has a storage trough in order to better retain cooled air within the ice storage and thus minimize the heating of the stored ice elements.

[0022] In addition, the ice storage advantageously has a cooling device for active cooling in order to be able to keep the temperature in the ice storage below 0°C at all times.

[0023] Advantageously, the ice-preserving system is designed as a mobile unit. For example, the ice-making system can be installed inside a container. This allows the ice-preserving system to be set up flexibly and relatively close to the object to be protected, allowing the fire barrier to be erected with minimal transport effort for the ice elements.

[0024] It is advantageous if the mobile unit can be transported by means of a transport vehicle, on which additional devices for positioning the mobile ice elements can be transported, such as a forklift for ice blocks or a pump line for pourable ice elements.

[0025] Furthermore, the above-mentioned object is achieved by a method for providing and erecting a fire protection barrier in one of the above-mentioned embodiments, in which in a first step the solid ice elements are produced by means of the ice production plant, in a second step the produced solid ice elements are arranged in the ice storage, wherein several stackable ice elements are arranged on a common pallet and in a third step the stored ice elements are at least partially removed from the ice storage if necessary and positioned in front of the object to be protected to erect the mobile fire protection barrier.In this way, the resources required to erect the fire barrier can be easily and permanently kept on hand. In the event of a fire, particularly rapid loading and transport of large quantities of ice elements is possible. An ice wall can be constructed particularly quickly. This ice wall can actively contribute to extinguishing the fire through its cooling effect when the ice elements heat up, subsequently during the transition from the solid to the liquid state, and further from the liquid to the gaseous state, as well as through the irrigation of the subsoil by escaping meltwater. This allows for particularly effective protection of the property in question in the event of a fire.

[0026] Preferably, in the second step, the stackable ice elements are arranged at least partially separately from one another in order to prevent the ice elements from freezing together and thereby ensure their easy handling when erecting an ice wall.

[0027] Furthermore, it is advantageous if the fire barrier is constructed in the form of an ice or fire barrier wall made of stackable ice elements. This allows both the height and length of the fire barrier to be adjusted relatively quickly and easily to the height or length of the object to be protected.

[0028] Advantageously, the ice wall is erected using a forklift truck or, in particular, an off-road wheel loader, in order to enable particularly rapid construction of the ice wall with large ice blocks, in particular those that cannot be carried manually.

[0029] It is pointed out that all features of the subject matter according to the invention described above are interchangeable or combinable with one another, unless an exchange or combination thereof is excluded for technical reasons.

[0040] Figure 12 shows a provision arrangement for the production and provision of solid ice elements for the construction of a fire barrier and

[0041] Figure 13 shows a mobile production plant for the production of solid ice elements.

[0042] Fig. 1 shows a fire barrier 2 for the on-demand protection of an object 4 against a fire event 6. The object 4 to be protected can, for example, be a building, such as a residential building or an industrial or infrastructure facility, a forest, an enclosure or stable, and / or another agricultural facility. The fire barrier 2 has an ice wall 8 formed from a plurality of solid ice elements 10.

[0043] In the embodiment of the fire barrier 2 shown in Figure 1, the ice wall 8 is constructed in the form of a brick ice wall 12 composed of stackable ice elements 10. The stackable ice elements 10 are uniformly shaped and each essentially consists of a cuboid-shaped ice block 15 as shown in Figure 2.

[0044] On a first side 14 formed by an upper side of the ice block 15, the stackable ice element 10 has a form-fitting contour 16, which is complementary to a form-fitting counter-contour 18 on a second side 20 formed by an underside of the ice block 15. The form-fitting contour 16 is formed, for example, by an arrangement of plug-in means 22, while the form-fitting counter-contour 18 forms complementary mating plug-in means 24. The plug-in means 22 and mating plug-in means 24 are formed, for example, by studs 26 protruding from the ice block 15 and stud receptacles 28 incorporated into the ice block 15.

[0045] Figure 3 shows an alternative embodiment of the stackable ice element 10, in which the form-fitting contour 16 is formed by a plurality of through bars 30 that extend on the top side across the entire width of the ice block 15. The form-fitting counter-contour 18 has complementary through grooves 32 on the underside, which also extend across the entire width of the ice block 15. Two of the through grooves 32 are spaced apart by a distance A from one another and each have a width B, which are dimensioned such that a fork carriage of a forklift truck (not shown) can be engaged therewith.

[0046] The form-fitting contours 16 and form-fitting counter-contours 18 of the uniformly shaped stackable ice elements 10 thus always ensure a form-fitting connection between two adjacent ice elements 10 of the same shape, in order to increase the stability and tightness of the erected ice wall 12. In the illustrated embodiments of the ice wall 12 and the stackable ice elements 10 according to Figures 1 to 3, the form-fitting connection is provided between two vertically adjacent ice elements 10. Alternatively or additionally, the form-fitting contours 16 and form-fitting counter-contours 18 can also be provided on mutually opposite side surfaces of the respective ice blocks 15, in order to also be able to establish a form-fitting connection and a high degree of tightness between two horizontally adjacent ice elements 10 (not shown).This can effectively block the spread of smoke, especially near the ground.

[0047] As can also be seen from Figures 2 and 3, a gripping aid 34 can additionally be provided on the ice block 15, for example in the form of two gripping recesses 36 integrated into the ice block 15, which extend horizontally into the ice block 15 on two opposite side surfaces. This allows the stackable ice element 10 to be more easily transported and handled in order to erect the ice wall 8 or the ice wall 12.

[0048] As can also be seen from Figures 2 and 3, at least one cavity 38 can additionally be provided in the ice block 15, in which an additional extinguishing agent L is accommodated or enclosed. The extinguishing agent L can, for example, be formed by CO2, which displaces oxygen upon escaping from a melting ice element 10 and can thereby actively suppress the fire event 6. Alternatively or in addition to the design of the fire protection barrier 2 according to Figure 1, in the form of the single-shell ice wall 12 constructed from the stackable ice elements 10, the ice wall 8 according to Figure 4 can have a pyramid-like structure of the ice blocks 15 in cross-section in order to ensure more stable footing and to provide a larger volume of ice or meltwater.

[0049] Furthermore, according to Figure 5, the number of plug-in elements 22 and counter-plug-in elements 24 provided on the top side 14 and the bottom side 20 of the ice blocks 15 can be selected, in contrast to the exemplary illustration in Figures 1 to 3, such that the ice blocks 15 can be installed offset from one another by exactly half a length. This allows for particularly high stability when constructing the ice wall 8.

[0050] Furthermore, alternatively or in addition to constructing the ice wall 8 with masonry ice blocks 15, the fire barrier 2, as shown in Figures 6 and 7, can be formed by depositing pourable solid ice elements 40. The pourable ice elements 40 can be handled in large quantities as bulk material and, for example, picked up and distributed using excavators or wheel loaders, and transported over long distances by truck. Alternatively, the pourable solid ice elements 40 can be formed from pumpable crushed ice, which can be extracted from a reservoir via pump lines and distributed in the area of ​​the fire barrier 2.

[0051] It is particularly preferred if a combination of solid, stackable ice elements 10 and pourable ice elements 40 is used to produce the ice wall 8. In this way, for example, according to Figure 6, the pyramid-shaped ice wall 8 according to Figure 4 can be additionally covered from above, at least in sections, with pumpable or pourable ice elements 40, such as in particular on the side of the fire incident 6. This allows the ice wall 8 to be additionally cooled and reinforced, particularly in sections close to the fire, in order to maintain its height and thus its full protective effect. The pumpable ice elements 40 can be distributed on the ice wall 8, for example, using hoses 41. The pumpable ice elements 40 are preferably produced in a mobile pumping system 43, which can be operated on a respective section of the ice wall 8 as needed.Preferably, the distribution of the pumpable ice elements 40 takes place approximately 80% on the side of the ice wall 8 facing the fire event 6 and 20% on the side facing away from the fire event.

[0052] Furthermore, when combining solid stackable ice elements 10 and pourable ice elements 40 according to Figure 7, for example, a double-walled fire protection barrier 2 can be provided with two ice walls 12 erected parallel to each other and a bed of pourable ice elements 40 accommodated therebetween.

[0053] Alternatively or additionally, the pourable ice elements 40 can also be piled onto a single-, double-, or multi-walled ice wall 12 constructed from stackable ice elements 10 as shown in Figure 8 in order to increase the ice mass and thus the cooling effect and extinguishing water quantity of the respective fire protection barrier 2. For example, as shown, at least one riser 37, preferably several risers 37 distributed over the length of the fire protection barrier 2, can be installed for this purpose, which is supplied with pumpable or pourable ice elements 40 via a supply line 39 arranged behind the fire protection barrier 2 in order to repeatedly or continuously pile these ice elements onto the side of the ice wall 8 facing the fire event 6 over the duration of a fire event 6.

[0054] In a further alternative or additional application according to Figure 9, the combination of solid, stackable ice elements 10 and pourable ice elements 40 can also be used to construct a rescue corridor 45. For this purpose, for example, in the area of ​​the fire incident 6, a section of an escape route 47 is covered with pumpable or pourable ice elements 40, thus creating a corridor. Subsequently, an ice wall 8 is erected at both edges of the escape route 47 or the corridor to complete a first protected section of the rescue corridor 45. Starting from this first section, further sections can then be created in the same way to complete the required rescue corridor 45. The rescue corridor 45 can, for example, be constructed, as shown, wide enough to allow safe passage of people.

[0055] According to Figure 10, the rescue corridor 45 or its ice walls 8 can be additionally reinforced by ice elements 40 poured from the outside. For example, a mobile pumping system 43 can be used to pump and, if necessary, produce the pourable ice elements 40.

[0056] Figure 11 shows a further embodiment of the rescue corridor 45, in which it is designed to be sufficiently wide to allow protected passage of vehicles 49, in particular rescue vehicles. Here, too, the ice walls 8 can be additionally reinforced by ice elements 40 deposited from the outside. To deposit the pumpable or pourable ice elements 40, a shovel vehicle 51, such as in particular a wheel loader, can be used as an alternative or in addition to a mobile pumping system 43 according to Figure 10 and / or a riser 37 according to Figure 8, as shown.

[0057] Figure 12 shows a storage arrangement 42 for the production and provision of the solid ice elements 10 and 40 for the flexible construction of a fire protection barrier 2 in a nearby area. For this purpose, the storage arrangement comprises an ice production system 44, which serves to produce the stackable ice elements 10 and / or the pourable ice elements 40.

[0058] Furthermore, the storage arrangement 42 has an ice storage area 46 in which the produced solid ice elements 10 and 40 can be stored and made available for an extended period of time until a fire occurs in the immediate vicinity. For this purpose, the ice storage area 46 has a temperature-insulated housing 48 and a cooling device 50 so that the temperature in the ice storage area 46 can be kept below 0° Celsius at all times. The ice storage area 46 is preferably formed at least partially by a storage trough 52 in order to minimize cooling losses over the storage period of the solid ice elements 10 and 40. Separating elements 54 made of solid or flexible material are preferably provided between the stackable ice elements 10 stored in the ice storage area 46 to prevent adjacent ice elements 10 from freezing together over the storage period.In addition, the stackable ice elements 10 are at least partially stored on pallets 56 in order to be able to remove a large number of stackable ice elements 10 from the ice storage 46 in a short time if necessary and to transport them to a desired location, for example by means of a forklift truck G and / or by means of other transport vehicles.

[0059] For the long-term provision of the solid ice elements 10 and 40 for the on-demand construction of a fire barrier 2, the stackable ice elements 10 and / or pourable ice elements 40 are produced in the provision arrangement 42 with the aid of the ice production system 44 in a first step S1. Following their production, the solid ice elements 10 and / or 40 are then arranged in the ice storage 46 in a second step. In this case, the stackable ice elements 10 are arranged individually from one another using the separating elements 54, if necessary, and several stackable ice elements 10 are arranged on a common pallet 56.

[0060] If a fire event 6 occurs in the vicinity of the provision arrangement 42, the solid ice elements 10 and 40 produced and stored in this way can then be transported relatively quickly from the ice storage 46 in order to erect the fire protection barrier 2 on the object 4 to be protected. The ice blocks 15 can be transported to the respective site of use, for example, by means of a forklift G or loaded onto a transport vehicle. The pourable ice elements 40, on the other hand, can be pumped to the site of use or onto a transport vehicle, for example, by means of a pump line P. In any case, this allows for rapid erection of the fire protection barrier 2 with large quantities of ice elements 10 and / or 40.

[0061] Alternatively or in addition to the stationary production and provision of the solid ice elements 10 and 40 according to Figure 12, the ice production system 44 can also be provided within a mobile unit 60 according to Figure 13, for an even more flexible provision of a fire protection barrier 2, which is formed, for example, by a container. This allows the ice production system 44 to be carried, for example, on a transport vehicle 62 and transported directly to a respective site.

[0062] Using the ice production system 44, stackable ice elements 10 or ice blocks 15 and / or pourable ice elements 40 can be produced in a mobile manner. As shown, the ice production system 44 can remain on the transport vehicle 62 during the production of the ice elements 10; 40 to enable rapid onward transport. Alternatively, the ice production system 44 can also be set down at the respective site of use to enable the transport vehicle 62 to be used for other purposes. In any case, the mobile unit 60 has a water connection 64, via which the ice production system 44 can be supplied with the quantities of water required for ice production via a water supply 66 provided on site. The water supply 66 can be realized, for example, via a water hydrant, a fire pond, an irrigation ditch, a bank section, or the like.Depending on the type of water supply 66 available, the water can be drinking water, industrial water, waste water, salt water or fresh water.

[0063] In this mobile variant, too, the stackable ice elements 10 and / or the pourable ice elements 40 can be produced with the help of the ice production system 44 in the first step S1. Following their production, the ice elements 10 and / or 40 can, if necessary, be stored or made available in the second step S2 within the mobile unit 60 serving as the ice storage 46. In the third step S3, the ice elements 10 and / or 40 kept ready in the mobile unit 60 are removed and positioned in front of the object 4 to be protected to erect the fire barrier 2.

[0064] The ice blocks 15 can be removed and positioned, for example, by means of the forklift G. The pourable ice elements 40, on the other hand, can be pumped to the site of use, for example, by means of the pump line P. For this purpose, the forklift G and / or the pump line are preferably also transported on the transport vehicle 62 during the transport of the mobile unit 60.

[0065] In any case, this allows for rapid erection of the fire barrier 2 with large quantities of ice elements 10 and / or 40.

[0066] It is pointed out that all elements and features of the various embodiments of the subject matter according to the invention described above are interchangeable or combinable with one another, unless an exchange or combination thereof is excluded for technical reasons.
