Definitions
- the invention relates to a fire protection system for delaying and/or preventing a fire for a storage yard with a plurality of storage locations for storing objects, with the storage locations being arranged at least partially next to one another.
- Objects e.g. vehicles such as buses, trucks, cars and railway wagons, are parked or parked in storage yards, in particular in storage yards of large transport companies, but also of large forwarding companies or motor vehicle manufacturers.
- the vehicles are parked close together. If a vehicle catches fire, for example due to technical defects, the fire, regardless of the cause of the fire, usually spreads to the neighboring vehicles even before the fire brigade arrives and can initiate appropriate measures. As a result, a large number of vehicles are irreparably damaged or even completely destroyed in a very short time. The resulting financial damage often runs into millions.
- DE 196 18 072 A1 describes a fire extinguishing device for motor vehicles parked in multi-storey car parks, in storage areas that are open on all sides and/or partially open parking lots. Several extinguishing nozzles are assigned to each storage space or parking box, whereby several extinguishing nozzles are each opened via an exciter element.
- a fire protection system for preventing the spread of fire in a zone to be protected is known from EP 3 613 471 A1.
- the fire protection system has a water mist Deluge extinguishing system and sensors that detect and report incoming, recognizable or already existing fires and trigger the water mist Deluge extinguishing system in sections, with the water mist Deluge extinguishing system having nozzle groups with at least one each Has water mist nozzle, with which a water mist can be generated in targeted areas of the zone to be protected.
- US 2018/0200552 A1 describes an automatic firefighting system.
- One embodiment of the system attempts to provide fire suppression to the regions surrounding a fire area, thereby containing the fire in a limited area, but without flooding a larger area than is necessary to contain the fire.
- Sprinklers are also provided which can be selectively automatically activated, optionally in addition to the usual thermal trip. Sensors may be built into the sprinklers.
- sprinklers are provided which can report their activation via an electrical status change.
- Devices are also provided that reduce installation costs and increase the resolution of fire fighting and/or fire containment systems by enabling wireless communication between network nodes, such as flow switches, valve status switches and individual sensors, sprinklers and other connectors, and a control unit.
- a sprinkler system is known from DE 298 08 806 U1, in which sprinklers are arranged in such a way that smaller effective surfaces result, with the water impingement does not deviate from conventional sprinkler systems because the outflow rate of the individual sprinklers is reduced.
- DE 10 2020 133 630 A1 describes a fitting for firefighting and/or for cooling burning objects, comprising a hollow body that can be positioned on a substrate and has at least one inlet opening and a plurality of outlet openings, the hollow body being designed in such a way that an extinguishing agent can be enters the hollow body in a first direction of flow and exits from the hollow body in a second direction of flow, with the first and second directions of flow forming an angle that is not equal to zero, in particular 90°, to one another, and with the hollow body having at least one closable outlet opening which is connected to an inlet opening another fitting can be connected.
- a fire protection system for a storage yard with adjacent storage locations, with a fire detector for monitoring at least part of the adjacent storage locations and for detecting a fire in the monitored area, a pipe system with at least one pipeline each running between two adjacent storage locations for Transporting a non-combustible fluid, the pipelines each having a control valve for controlling the transport of the fluid and a discharge valve for emitting a mist of fluid upwardly into the area between the adjacent bins, and a control unit for controlling the control valves and the discharge valves in response to one of the fire detector fire detected in the area he monitors.
- the storage yard can be provided for the storage or parking of very different goods.
- the storage yard is a parking yard for vehicles.
- These vehicles can, for example, be vehicles already in operation that are parked overnight, such as buses and trains, for local or long-distance traffic, or vehicles that have just been completed, such as cars, before they are shipped.
- the storage areas are therefore preferably parking spaces for vehicles.
- the pipeline preferably runs in the longitudinal direction of the storage locations, ie parallel to the longer extent of the storage locations.
- “storage yard” is understood to mean a preferably uncovered area on which vehicles can be parked or parked.
- the storage yard includes storage locations that are preferably predetermined. This means that parking positions for vehicles, for example, are firmly defined in the warehouse. A vehicle should therefore only be parked within the predetermined or firmly defined storage location.
- the storage locations are next to one another, this means that two storage locations are arranged in such a way that their longitudinal axes are spaced apart from one another at essentially the same height and run essentially parallel to one another. With a sufficiently large number of storage locations, these can be arranged partially next to one another and partially one behind the other.
- the term "one behind the other” refers to an arrangement in which the longitudinal axes of two storage locations are essentially identical.
- non-flammable fluid is understood to mean a non-flammable liquid and a non-flammable foam, which is preferably also suitable for extinguishing a fire.
- Water is preferably provided as the non-flammable fluid.
- Fluid mist is understood to mean a heterogeneous mixture of solid or liquid suspended particles of the fluid in the ambient air.
- the pipelines running in the longitudinal direction of the storage locations between two adjacent storage locations are preferably arranged in the ground or close to the ground. In the case of a parking yard for vehicles, this means that practically the entire height of the side front of a vehicle can be protected from a fire by the fluid mist from below.
- control valve is understood to mean an actuator with which the fluid flow through the pipeline can be controlled, ie a respective pipeline can be opened or closed.
- the flow rate through the respective pipeline can preferably also be adjusted with the control valve.
- outlet valves are “controlled”, this means the opening and/or closing of the respective outlet valves.
- the “adjacent storage area” is understood to be the storage area that is directly next to a burning storage area.
- a storage place that is on fire is one that is on fire and/or where an object stored on it is on fire.
- a fluid mist can be sprayed specifically into the fire area between a burning storage space and a neighboring storage space.
- the heat or thermal energy that emanates from the burning storage area can be diverted and transported away upwards.
- the side walls of the neighboring vehicle are cooled and wetted with the fluid. As a result, the increase in the temperature of the side walls of a neighboring vehicle or the reaching of the ignition temperature can be delayed and ideally prevented.
- the fire protection system thus ensures a fire protection measure that is particularly suitable for unroofed storage yards and can be carried out at short notice to delay and/or prevent a fire in a neighboring vehicle.
- Emitting a fluid mist represents a fire delay or fire prevention measure.
- the actual firefighting through suitable extinguishing measures is primarily the responsibility of the fire brigade and must usually be carried out additionally.
- the fire protection system is an instrument that is used in particular for the period between the outbreak of a fire and the arrival of the fire brigade and is intended to delay or prevent the fire from spreading to neighboring vehicles.
- the control unit is preferably set up and connected to the control valves and the outlet valves in such a way that the control valves and the outlet valves can be controlled individually and independently of one another. This makes it possible to generate a fluid mist only where a fire has actually been detected.
- the outlet valves preferably have fluid mist nozzles.
- the openings of the fluid mist nozzles are sufficiently small to produce an even fluid mist.
- the diameter of the openings is selected such that the droplets of the fluid mist have an average diameter that is preferably less than 50 ⁇ m, particularly preferably less than 25 ⁇ m, very particularly preferably less than 10 ⁇ m. If the outlet valves are located on the floor or close to the floor, the fluid mist can escape from the floor under high pressure through the fluid mist nozzles upwards into the combustion chamber.
- the pipe system is in particular coupled to a fluid reservoir and/or to an inflow line.
- the fire detector is designed to determine the fire temperature of the detected fire.
- the Fire detector an infrared camera.
- the fire detector is not only designed to detect a fire, but also to determine the temperature of the fire.
- the fire can be characterized on the basis of the fire temperature.
- the fire temperature shows, for example, how advanced the fire is. Based on the fire temperature, the fire can be divided in particular into a preliminary stage, for example at a temperature between 150°C and 300°C, and into a main stage, for example at a temperature greater than 300°C. Depending on the respective level, different fire protection measures can be initiated.
- At least two outlet valves are arranged between two storage locations arranged next to one another.
- the outlet valves are preferably arranged in such a way that the most uniform possible distribution of the fluid mist is made possible.
- the pipelines have at least one removal device for removing the fluid.
- firefighters can set up a water supply at the withdrawal point to fight the fire, so that the distances covered by the water supply are kept to a minimum, since water can be drawn in the immediate vicinity of the fire site.
- the storage yard can also be provided within the scope of the invention to design the storage yard in a special way.
- the storage locations are divided into at least two sectors and each sector is individually coupled to the control unit via a central point.
- a link via a bus system, eg via one of the usual network topologies (eg ring-shaped). This ensures short cable routes in the sectors and improved management of the fire protection system. For example, if errors occur within the fire protection system, they can be limited to a specific sector.
- a light signal device that can be controlled by the control unit is arranged at each storage location.
- the light signal device can light up in different colors and thus indicate different states.
- the light signal devices preferably serve as a guidance system for directing or guiding an employee and/or the fire brigade to the source of the fire, so that the employee and/or the fire brigade can reach the source of the fire without any delay that would be caused by orienting and searching for an affected storage location.
- a sensor coupled to the control unit is provided at each storage location for detecting the occupancy status of the respective storage location.
- a sensor can be part of the storage area but also part of a vehicle parked in the storage area.
- the control unit is provided with information which shows whether a storage space is occupied by a vehicle or not. This can be taken into account in particular when controlling the exhaust valves.
- the occupancy status can be used to determine which and how many vehicles are in the immediate vicinity of the burning vehicle in order to prevent it from spreading at an early stage of the fire through organizational measures, such as driving away or moving parking spaces from neighboring vehicles counteract the fire.
- Transporting a non-combustible fluid into the pipeline running between the affected storage area and the adjacent storage area by appropriately actuating the control valve of this pipeline and releasing the air in the pipeline running between the affected storage area and the adjacent storage area by opening at least one not between the affected storage area and the adjacent storage location arranged exhaust valve, and Opening at least one outlet valve arranged between the affected storage location and the adjacent storage location in order to emit the fluid mist.
- the pipe system does not have to be permanently filled with fluid. In this way, frost damage in particular can be avoided.
- this air is not discharged via the outlet valves directly in the area of the fire in order not to fuel the fire any further. Rather, the air is discharged via outlet valves that are not located at the storage location in question, but in particular are sufficiently far away from the storage location in question.
- the method comprises the following additional method steps:
- the fire can be characterized on the basis of the fire temperature.
- the fire temperature shows, for example, how advanced the fire is.
- the fire is divided into a preliminary stage, for example at a temperature greater than 150°C, and a main stage, for example at a temperature greater than 300°C.
- Different fire protection measures are initiated depending on the respective level.
- the preliminary stage only the ready-to-extinguish state is created. This means that the pipeline is vented and filled with fluid.
- organizational measures such as re-parking or removing vehicles, can be carried out or firefighting can be attempted, in particular using fire extinguishers.
- the method also includes at least one of the following further method steps:
- employees and/or the fire brigade are directed or guided to the source of the fire via the light signal device.
- the employee and/or the fire brigade can thus reach the seat of the fire without any time delay, which is caused by orienting and searching for an affected storage location.
- the method comprises the following additional method step:
- the information about the occupancy status of the storage locations can be taken into account in particular when controlling the outlet valves. If no object, such as a vehicle, is parked in an adjacent storage area, it is generally not absolutely necessary for the exhaust valves between the affected storage area and the adjacent empty storage area to be opened, since no object parked next to the burning storage area needs to be protected from a fire. This reduces the amount of water required and improves the efficiency of the fire protection system. Furthermore, based on the information about the occupancy status of the storage areas, it can be determined which and how many objects are parked in the immediate vicinity of the burning storage area, so that in an early stage of the fire organizational measures, such as driving away or changing parking spaces from neighboring vehicles, can be reacted to.
- FIG. 1b schematically shows a fire protection system according to the preferred embodiment of the invention from Fig. la in a second scenario
- FIG. 2 schematically shows a fire protection system according to a further exemplary embodiment of the invention
- FIG. 3 schematically shows a method for operating a fire protection system according to a preferred exemplary embodiment of the invention.
- a fire protection system 1 can be seen schematically in FIG. 1a and FIG. 1b.
- a vehicle 4 is arranged on each of the three fixed storage locations 3A, 3B, 3C.
- the vehicles 4 are trains.
- the pipelines 8B, 8C run between the storage locations 3A, 3B, 3C.
- a pipeline 8A, 8D also runs next to the outer parking space 3A, 3C.
- Two outlet valves 9 are arranged in the pipeline 8A, 8B, 8C, 8D along the longitudinal side of the vehicles, which runs into the plane of the drawing in FIGS. 1a and 1b.
- the pipe system 6 is located above and near the floor 7.
- a fire detector 5 here in the form of an infrared camera, monitors the storage locations 3A, 3B, 3C.
- a fire 2 develops on the vehicle 4 ′, which is parked in the middle storage space 3B. The fire 2 is detected by the fire detector 5 .
- the pipelines between the affected storage area 3B, on which the burning vehicle 4' is parked, and the neighboring storage areas 3A, 3C are filled with the fluid and the outlet valves 9 between the affected storage area 3B and the neighboring storage areas 3A and 3C are opened, so that a fluid mist 10 can escape into the fire space between the burning vehicle 4 ′ and the neighboring vehicles 4 .
- the fluid mist 10 redirects the heat radiated from the burning vehicle 4' upwards so that it does not reach the neighboring vehicles, if at all.
- the longitudinal sides of the neighboring vehicles 4 are cooled so that they heat up less and the ignition temperature at which the vehicle self-ignites is reached later or, ideally, not at all.
- the occupancy states are recorded via the sensors 15 .
- the control unit 12 receives the information via the sensors 15 that the storage space 3A is not occupied and that the storage spaces 3B, 3C are occupied. Accordingly, only the outlet valves 9 which are arranged between the burning vehicle 4' and the neighboring vehicle 4 are opened. The outlet valves 9 between the affected storage area 3B and the empty storage area 3A are not opened, since no vehicle 4 that needs to be protected from a fire 2 is parked on this side.
- the storage yard includes a large number of firmly defined storage locations 3A, 3B, 3C, 3D, which are arranged in a row next to one another. Several rows of storage locations arranged next to one another are arranged one behind the other, so that the storage locations are arranged in a chessboard pattern overall.
- the storage areas are divided into sectors I, II, III. Each sector I, II, III is connected to the control unit 12.
- Each pipeline 8A, 8B, 8C, 8D, 8E can be opened or blocked via a control valve 11.
- Two outlet valves 9 are arranged in each case next to a longitudinal side of each storage location 3A, 3B, 3C, 3D in the respective pipeline 8A, 8B, 8C, 8D, 8E.
- the control unit 12 controls both the control valves 11 and the outlet valves 9.
- the pipe system 6 is connected to a fluid reservoir 14, from which the required quantity of fluid is drawn and transported via pumps 16 into the pipes 8A, 8B, 8C, 8D, 8E.
- Each pipe 8A, 8B. 8C, 8D, 8E has at least one removal point 13 at which the fluid can also be removed for firefighting by the fire brigade.
- the burning vehicle 4' is parked in the affected storage area 3B.
- the pipelines 8B, 8C that run between the affected storage area 3B and the neighboring storage areas 3A, 3C are arranged, opened by opening the respective control valve 11 and filled by activating the pump 16 with fluid.
- the air in the ducts 8B, 8C is discharged via outlet valves 9' which are far enough away from the fire 2 in order not to stoke the fire 2 any further.
- FIG. 3 shows a schematic sequence of the method for operating the fire protection system according to a preferred exemplary embodiment of the invention.
- a burning vehicle 4' is detected Sla and the affected storage area on which the burning vehicle 4' is parked is localized in the network of the large number of storage areas Slb.
- the fire temperature is then determined S5 in order to then classify the fire S6.
- the affected storage location 3B can optionally be displayed visually via the light signal device S7.
- the occupancy status of each individual storage location 3A, 3B, 3C, 3D can optionally be queried S8 in order to obtain an overview of which and how many vehicles 4 are parked in the immediate vicinity of the burning vehicle 4'.
- the ready-to-extinguish state is then established. This means that the fluid is transported into the affected pipelines 8B, 8C and the pipelines 8B, 8C are filled with the fluid S2. At the same time, the pipelines 8B, 8C are vented in that the air in the pipelines 8B, 8C is released via at least one outlet valve S3 that is sufficiently far away from the fire.
- the ready-to-fire condition occurs when the pipelines 8B, 8C are vented and filled with fluid. If fire 2 has progressed so far that the main stage is reached, the fire delay measures are initiated. First, it is determined on which storage locations 3A, 3B, 3C, 3D actual vehicles 4 are parked S8.
- the outlet valves 9 between the affected storage space 3B and the adjacent occupied storage space are opened S4, so that a secondary fluid can escape into the space between the burning vehicle 4' and the adjacent vehicle 4.
- the fluid mist 10 represents a fire retardation or fire prevention measure.
