Description

Technical Field

[0001] The present invention relates to a fire protection device including a fire protection cover that can cover a conventional vehicle or a potentially flammable object such as a battery-powered vehicle positioned in a parking space in order to counteract spreading combustion that spreads from an object or flashover that spreads to an object, and a method for preventing or suppressing a fire of an object positioned in such a manner.

[0002] This type of fire protection device equipped with a fire protection cover or a fire extinguishing cover is suggested to be known from the German Utility Model No. 202020106119. This fire extinguishing cover / fire protection cover is used to cover, in particular, battery-powered electric vehicles in order to cut off a fire and suppress its further spread. The fire extinguishing cover is folded and stored in a transport box, and the fire protection device has an alarm device that triggers an alarm and further recognizes, for example, when the transport box deviates from its storage space for the request of a specialized rescue team by a fire department. The fire extinguishing cover must be able to withstand the heat of a fire until the arrival of a specialized rescue team. Positioning a fire extinguishing cover on a vehicle is rather laborious because of its relatively heavy weight, and in many cases, valuable time until the occurrence of a fire is recognized and extinguished is lost.

[0003] The Chinese Utility Model No. 215461549 discloses a fire protection device that is, for example, oriented longitudinally with respect to a vehicle and mounted above the vehicle in a garage. In this case, the fire protection cover is grouped into two rolls extending longitudinally, and these rolls are dissociable between two half-shells that can be automatically deployed laterally during a fire in a longitudinal central transfer region in a holding device having an electromagnet and are held so as to spread over the vehicle.

[0004] German Utility Model Specification No. 202016008488 discloses a fire protection device object with a fire extinguishing cover housed inside a box, and this fire extinguishing cover can be taken out through an opening in the lower part of the box without opening the box.

[0005] German Utility Model Specification No. 202022101021 discloses a flame protection cover for covering an automobile with a surface element made of a high-temperature fabric.

[0006] German Patent Application Publication No. 102021005719 discloses a further fire protection device with at least one flexible fire extinguishing cover, and this fire extinguishing cover is provided with at least one fastening belt formed as an endless loop for fastening the fire extinguishing cover. By using this fastening belt, the fire extinguishing cover can be easily and optionally fastened, and thereby, for example, it can be guaranteed for the object.

[0007] German Utility Model Specification No. 202019106371 discloses a fire extinguishing cover having a three-layer structure composed of a glass fabric and a second layer of bentonite disposed therebetween. In this case, this structure provides a sufficient compromise in terms of weight, rigidity, fire resistance, and airtightness or filtering effect. For the handling of the fire extinguishing cover, it is proposed that the fire extinguishing cover be provided with a handling device such as a loop-shaped handgrip made of, for example, webbing or edge tape on the edge side. Additionally, fixing means, particularly Velcro fasteners, are attached on the edge side. This fire extinguishing cover must be applicable for multiple purposes and effectively protect the surroundings from the result of the burning of a lithium-ion battery. Such a fire extinguishing cover cannot be easily handled for large-volume objects such as automobiles.

[0008] German Patent Application Publication No. 102016225871 discloses a fire and smoke protection system with a self-expanding cover including a self-expanding shield. The shield struts are formed by hose-shaped conduits that can be pressurized with a pressure medium. For example, commercial vehicles equipped with such a fire and smoke protection system have also been proposed to block conveyed goods in the event of a fire or smoke. This device can also be applied to passenger cars in, for example, automobile factories or underground parking lots. Such structural parts are relatively complex, and in many cases, the spatial given conditions for them are not favorable either.

[0009] German Utility Model No. 202013102471 discloses a device for emergency activities in a building, including a housing and the like, and in the housing, emergency response means in the event of a fire, especially a fire extinguisher and a fire cover, etc. are provided. This housing is connected to a smoke detector or a reporting center via a wireless link for activating the emergency device.

[0010] German Patent Application Publication No. 102020102191 discloses a device for capturing emergency situations in the area of a motor vehicle to derive threats in the surrounding environment and, in some cases, output an emergency signal, and a method for automatically determining the current value of a state variable of a vehicle battery.

[0011] German Patent Application Publication No. 102017213408 discloses an autonomous charging and fire truck including, among other things, a fire extinguishing device.

[0012] The problem underlying the present invention is to provide a fire protection device in the form described at the beginning that can provide an as effective as possible containment of fire spread for objects placed in a parking space, especially for battery-powered vehicles, and can provide a good and effective method for fire protection.

[0013] This problem is solved in a fire protection device having the features of claim 1 or by the method according to claim 13. According to the invention, here a fire protection cover is compactly grouped into a package, in particular folded and / or wound up on a shaft, and is accommodated in a box-shaped housing which can be attached to or is attached to a parking space and is connected to a pulling-out device. Using the pulling-out device, it is assumed that in the event of a fire or a fire hazard, the fire protection cover can completely cover the object manually or automatically so that its lateral section is completely placed around the floor of the parking space in order to prevent the inflow of oxygen as well as possible and thus to block the vehicle as well as possible.

[0014] In this method, it is assumed that the fire protection cover is pulled out manually or automatically from the housing onto the object using the pulling-out device and then lowered.

[0015] Due to these features, the fire protection device provides a simple manual operation in the event of a fire or a recognized fire hazard, or also a spontaneous and automatic operation when pulling out a complete fire protection cover or a fire extinguishing cover onto an object located in a parking space, in particular an electrically battery-powered vehicle, and further provides for lowering the edge section of the fire protection cover completely or at least sufficiently around the object, thereby effectively countering the spread of fire until the arrival of the fire brigade or fire department and the continuation of further fire extinguishing activities. Thereby, the means according to the invention substantially contribute to an efficient and early fire extinguishing operation.

[0016] An advantageous configuration of the housing of a fire protection device attached to or attachable to a parking space is that the housing, whose longitudinal axis is attached or attachable, in particular, transversely or at right angles to the longitudinal direction of the vehicle, has a wall section that shields a draw-out opening extending longitudinally with respect to the housing, and the wall section is automatically separable based on an opening signal triggered manually or using a sensor assembly for the release of the draw-out opening in the event of a fire hazard. On the one hand, the fire protection cover is protected using the associated mechanism, damage-protected, and housed within the housing, and on the other hand, it is released for easy and immediate application as needed. For example, the wall section may be formed as a cover that extends in the direction of the longitudinal axis of the housing and folds downward, or may be formed as a shiftable cover.

[0017] To move the fire protection cover out of the housing in a draw-out manner, it is advantageously assumed that the fire protection cover is wound up or folded and housed within the housing and is connected to the draw-out means.

[0018] An advantageous configuration for installation in a parking space for application to an object, in particular a vehicle, is that the housing is attached to a parking space partition, in particular a wall section or a cover, in front of and above the object in the draw-out direction, and deflection means are attached to a support section behind and above the object, and in particular two draw-out means in the form of towing ropes are connected to the fire protection cover so as to extend in the draw-out direction at the side and above the object and are guided around the deflection means, whereby the fire protection cover can be drawn out over the entire length of the object in the draw-out direction and then the edge section can be lowered onto the floor of the parking space. Then, when the side section of the fire protection cover drawn out over the object is lowered, it loosens due to its flexibility and its own weight and abuts against the floor of the parking space so as to sufficiently block the air flow from the surroundings to the object. The side section of the fire protection cover as well as the front and rear sections of the fire protection cover are configured with a sufficiently large area to be placed on the floor around the parking space.

[0019] To achieve rapidly lowering the fire cover onto the floor, advantageously, in order to lower the fire cover onto the floor, there is assumed to be a separating device for separating the connecting part of the pulling means from the fire cover behind the object (detached from the housing), or a separating device for cutting the pulling means, behind the object. After separating the pulling means from the fire cover or after cutting the pulling means itself, the fire cover can drop onto the object or the vehicle without being hindered, and its side section can be placed on the floor around the vehicle.

[0020] An advantageous configuration for the automatic operation of the fire protection device consists in that a pulling device for automatically pulling out the fire cover, which is connected in particular to the control device, is coupled to a drive device, which can be activated manually or in response to a notification signal from one or more fire detectors. When triggered in a sensor-based manner by a notification signal during a fire, the fire cover is positioned as required without the help of a manual operation regarding the object, but can be moved more appropriately by the user if required. At the same time, the notification signal can be used to trigger an alarm (for example, acoustically, optically, or wirelessly transmitted), or to switch off the fire alarm equipment (BMA) (if available) to issue an alarm to the fire protection personnel or the fire brigade for fire extinguishing activities.

[0021] To provide drive energy for the drive device, various means are possible, for example, an electrical, pneumatic, hydraulic, or mechanical energy source, in particular an energy source having a spring device, for providing the drive energy of the drive device. In this case, it is advantageous to have a self-sufficient energy source that continues to function even during a fire, especially without power, which is, for example, a preloaded mechanical spring device whose stored energy is released, for example, by a notification signal or a manual operation when triggered by an activation signal, thereby operating the drive device, for example, the pulling means being pulled out via a deflection means for positioning the fire cover on the object.

[0022] Advantageously, in order to provide the driving energy of the driving device, it is assumed that there is an electrical, pneumatic, hydraulic, or mechanical energy source, in particular an energy source having a spring device.

[0023] Furthermore, in order to pull out and position the fireproof cover, advantageously, it is assumed that the driving device is connected to the pulling-out means.

[0024] A further advantageous configuration in terms of structure and function consists in that the driving device is configured to drive rotationally and comprises actuating means for a winding device or pulling-out means for applying a tensile force. The actuating means capable of applying a tensile force to the pulling-out means is, for example, a friction roller for transporting the pulling-out means.

[0025] A further advantageous means for fire extinguishing operations consists in that the fireproof cover is made of a high-performance material designed for a temperature up to 1500 °C for continuous loading (more than 24 hours), or up to 2500 °C for maximum load resistance (about 15 minutes), for example according to the manufacturer's description.

[0026] Advantageous means for adapting to local given situations or different object dimensions consist in that height adjustment and / or width adjustment devices (H, B, H + B) are provided, and via the height adjustment and / or width adjustment devices (H, B, H + B), the housing is attached to or attachable to a parking space in a height-adjustable and / or width-adjustable manner.

[0027] In this method, an advantageous procedure consists in that the pulling-out device for pulling out has pulling-out means, in particular a towing rope, connected to the fireproof cover, and the pulling-out means is guided via a deflecting element and is cut during a fire in order to lower the pulled-out fireproof cover.

[0028] Hereinafter, the present invention will be described in more detail based on embodiments with reference to the drawings.

Brief Description of the Drawings

[0029]

Figure 1

[0030] The embodiment shown in FIG. 1 schematically depicts a parking space 5 on which an object is placed and a fire protection device arranged in the parking space and attached thereon. By using this fire protection device, for example, until a fire protection assistant or a fire brigade arrives, an object that may be exposed to flames can be sufficiently protected from spreading fire. The object is, in this example, a vehicle, particularly a vehicle 6 that is electrically driven using a battery (for example, a lithium-ion battery). In this case, the parking space 5 may be a parking space in a garage such as an underground parking lot or a carport, or a charging space for charging the battery.

[0031] A front partition, for example a solid wall portion, or a partition wall portion structured from struts, for example, is preferably located at least at the height of the upper surface of the object or the vehicle 6 when the vehicle is parked facing forward. A vertically elongated housing 6 in the form of a cassette or a box is horizontally attached (with respect to the gravitational or surveying direction), for example, via a height adjustment device H and / or a width adjustment device B. This housing 6 extends longitudinally, for example, over the width of the vehicle 6 or the possible parking space of the vehicle 6. Inside the housing 1, a fireproof cover 3 (also referred to as a fire extinguishing cover), which is compressed and bundled in a package 32, for example wound up or alternatively folded, is accommodated. This fireproof cover usually has a standard size of 6×8 m. In the state shown in FIG. 1, the fireproof cover 3 is sufficiently pulled out (in the pulling direction Z) from the housing 1 onto the vehicle 6 up to the rear part thereof. The flexible and relatively heavy fireproof cover 3 has side sections 31 hanging down on both sides following the upper section 30. These side sections 31 are folded inwards, for example, in a wound-up or folded state for storage in the housing 1. It is also conceivable to form the longitudinal extension of the housing 1 thinner than the vehicle 6, for example, or to configure the length extension of the housing 1 to be adjustable to adapt to different parking space widths, and to adapt the width of the fireproof cover 3 to the longitudinal extension of the housing 1 by folding the fireproof cover 3 once or multiple times longitudinally, for example, so that the fireproof cover 3 can be accommodated in the housing 1.

[0032] In order to pull out the fireproof cover 3, there is a pulling device 4. This pulling device 4 has pulling means in the form of, in particular, two lateral pulling ropes 40, which are connected to the fireproof cover 3, whereby, via the pulling means for pulling out the fireproof cover 3, in an imminent or already occurring fire situation, the fireproof cover 3 can be pulled out on the vehicle. The pulling means extends over a guiding device arranged at the rear side of the parking space or on the rear side of the vehicle, and the guiding device comprises, in particular, a deflecting device having deflecting means 41 such as a curved deflecting track or deflecting rollers. The pulling force for pulling out the fireproof cover 3 can be manually provided by one or more operators accessing the pulling means, or preferably by using the drive device 2. The drive device 2 can be arranged, for example, in the region of the deflecting means 41, or preferably in or on the housing 1, in which case the deflection of the pulling means is effected via the deflecting means 41.

[0033] The drive of the drive device 2 is effected pneumatically, hydraulically or mechanically, for example using an electric motor, in which case the energy source is preferably assigned to the fire protection device, whereby the drive device is self-supplied with energy in the event of a fire. One advantageous configuration consists in that the drive energy is mechanically stored in a spring device, for example using a coil spring. In order to pull out the fireproof cover 3, the pulling means, that is to say, for example, the pulling ropes 40 extending laterally in the longitudinal direction of the fireproof cover, the pulling direction, or laterally above the parking space or the vehicle 6, can be wound up using the winding device 20 of the pulling device 4. In so doing, the fireproof cover 3 is wound out, for example, by a winding device inside the housing 1 or is unfolded from a folded package.

[0034] The fire cover 3 is protected in a non-hazardous state and is preferably fully enclosed and accommodated in the housing 1. In order that the fire cover 3 can be rapidly extended over an object, in particular over a vehicle 6, in the event of a fire danger or fire, a wall section is attached to its front surface facing the parking space 5 or the vehicle 6, which is formed for example as a flap supported on a hinge and pivoting downwards due to gravity, or alternatively for example as a slider or is formed so as to be deployed upwards using a spring force. The opening signal can be triggered, for example manually by a user of the fire protection device, or automatically by means of a sensor assembly 11 which captures the fire danger or fire, in order to release the drawer opening. The drive control of the actuator device for the release of the wall section shielding the drawer opening is carried out in particular by means of the control device 10. For example, the opening signal is triggered in response to a notification signal of a fire detector, which subsequently releases or activates the drawer device 4 or the drive device 2 as well.

[0035] As soon as the fire cover 3 has been pulled out over the object or vehicle 6, it must be lowered onto the object or vehicle 6 so that its edge sections rest on the floor 51 around the vehicle, in order to exclude as much oxygen as possible from entering the area of ​​the object below the cover, at least until the arrival of firefighters or the fire brigade (e.g. after 5-20 minutes). The fire cover must provide a high degree of protection against the spread of fire for at least such a period of time, and may even be left on the object after the arrival of the fire brigade until the fire is extinguished or the "thermal runaway" has ceased.

[0036] The fireproof cover 3 is designed to meet high fireproof requirements. For example, the fireproof cover 3 is provided with a special coating and is made of a material with extremely high heat resistance based on silicate or graphite. Therefore, the flexible cover is relatively heavy. In order to quickly lower the drawn cover onto the object, a separating device 42, such as a cutting device, exists particularly in the region of the rear deflecting means 41. By this separating device 42, the drawing means, that is, particularly the towing rope 40, is cut or separated from the fireproof cover 3. In the rear and front regions, since the fireproof cover 3 sufficiently overlaps the object or the vehicle 6, after descending, it may be placed or adhered to the floor 51 together with the surrounding sections due to its weight. Similarly, a separating device may exist in the front region, or the front edge region of the fireproof cover 3 may be accommodated in a loose state within the housing 6, thereby enabling the drawn fireproof cover 3 to be easily lowered onto the floor. If additional positioning is required, this can be further carried out by the user. The support staff can issue an alarm, for example, via a fire detector acoustically, optically, and / or via a wireless reporting device.

[0037] In a first variant embodiment, the fireproof device presented here provides for manually positioning the fireproof cover 3 on a potentially flammable object on the parking space 5, particularly on the vehicle 6. The fireproof cover 3 can be attached to the wall 50 of the parking space 5 or is present so as to be stored in the attached housing 1 or the wall cassette. In this embodiment, the fireproof cover 3 is positioned by the user or a firefighter on a vehicle 6 that is potentially at risk or already burning. Subsequently, the fireproof cover 3 can be further finely adjusted by the user, taking into account its inherent protection, if necessary, by a small amount. At this configuration stage, the fireproof device functions, for example, completely mechanically and is sufficiently self-sufficient. In this case, supplementary manual operation interventions, such as a trigger signal for opening the cassette and / or the drawing of the fireproof cover 3 using the drawing device 4, are envisaged.

[0038] In a second variant, the opening of the housing or cassette can be triggered, for example, manually or automatically, and the pulling-out process can be triggered manually, but then runs automatically and self-sufficiently via the pulling-out device 4 and the drive device 2.

[0039] In a third variant embodiment, the automatic triggering of the pulling-out device 4 and the operation using the drive device 2 are assumed to be at least sufficiently self-sufficient, optionally using redundant means, under the triggering by the sensor assembly 11 and the control device 10, regardless of the presence or absence of an external energy supply. Thereby, the fire protection device provides, in particular, an advantageous protection means against the risk of fire in a vehicle 6 that is electrically driven using a battery such as a lithium-ion battery or an advantageous protection means in the event of a fire. In a last variant embodiment, it is further advantageously assumed that the start of the pulling-out process of the fire protection cover 5 is effected via an automatic operation using the sensor assembly 11, in which case, for example, there may be a dependency on two sensors or a further sensor, and an adaptation to the customer's requirements for full automatic or closed-loop control. For this purpose, an interface to a charging station or a wall box may advantageously be assumed for a non-energized switching during triggering. This variant embodiment functions completely automatically, for example, in the communication with the vehicle 6 and / or a further automated sensor system.
