Definitions

  • the present invention relates to a device for passivating a vehicle, in particular an electric vehicle, and a corresponding method for passivating a vehicle, in particular an electric vehicle.
  • lithium-ion batteries Li primary batteries
  • lithium ion batteries Li secondary batteries
  • energy density (Wh/kg) energy density (Wh/kg)
  • storage temperature or design the risk of a fire varies.
  • a battery that is deformed - for example due to an accident - can catch fire due to a chemical reaction, which is extremely difficult to extinguish.
  • the objective technical task is to create an extinguishing system that is as mobile as possible and can be used in areas that are difficult to access.
  • a device for passivating a vehicle in particular an electric vehicle, comprising at least two side walls, movement elements provided on the at least two side walls for moving the at least two side walls, connecting elements provided on the at least two side walls for connecting the at least two side walls to one another , and sealing elements provided on the at least two side walls for sealing between the at least two side walls and a floor located under the at least two side walls and/or for sealing the at least two side walls with one another.
  • the solution according to the invention advantageously does not require the use of a base part, which is the case with container solutions known in the prior art.
  • the device according to the invention uses the floor of the parking lot on which the vehicle to be passivated is parked.
  • the trough-like or trough-forming arrangement of the device according to the invention around the vehicle to be passivated can advantageously take place without lifting or moving the vehicle.
  • Each of the two side walls is advantageously designed in such a way that it already has a high intrinsic weight. Due to the movement elements, which are height-adjustable, each side wall is easy to manoeuvre. In this way it is possible for the side walls to be easily moved and arranged around a damaged vehicle.
  • each of the side walls is provided with connecting elements and seals in the floor area and on the horizontal connecting surfaces.
  • Rollers are preferably provided as movement elements. These enable easy maneuvering despite the high weight of the side walls.
  • rollers are attached to each side wall, which allow the side walls to be easily manoeuvred. Once the side walls are in position and connected to each other, the rollers can be removed from the floor using a crank or other devices until the side walls are completely in contact with the floor and the sealing element thus prevents the extinguishing agent from escaping later.
  • other means for moving the side walls can be provided which, for example, allow the side walls to slide or move.
  • a clamping device arranged on one of the at least two side walls and an engagement device arranged on another of the at least two side walls are provided as connecting elements.
  • An end face of at least one of the at least two side walls advantageously has an essentially U-shaped profile which can be brought into engagement with another end face of one of the at least two side walls.
  • a firm hold between two adjacently arranged side walls is thus possible without connecting elements having to be arranged on both sides of a side wall.
  • the fasteners are not to be arranged within a space or interior space defined by the side walls, which forms the tub.
  • At least one of the at least two side walls preferably has a cavity which is designed to accommodate an extinguishing agent.
  • the additional weight of the extinguishing agent ensures that no water escapes towards the ground, even on uneven road surfaces.
  • the contact pressure to the floor can be increased by increasing the level of extinguishing agent in the cavity.
  • each side wall is constructed in such a way that it consists of a base frame that is planked and sealed on both sides. This creates cavities that can be flooded, which are connected to one another by recesses in the base frame. This ensures that the extinguishing agent is evenly distributed during the filling process.
  • a further embodiment provides that at least one of the at least two side walls has a connection for filling a space defined by the at least two side walls and/or a cavity in one of the at least two side walls with an extinguishing agent.
  • a vehicle located within the space can be completely covered with an extinguishing agent via the connection for filling a space defined by the at least two side walls.
  • the connection for filling a cavity in one of the at least two side walls serves to increase the dead weight of the same.
  • a C-coupling or a G 1/2 inch thread--common for consumers-- is preferably provided as the connection. It is explicitly pointed out that the connection can be provided for simultaneously filling the cavity of a side wall or the side walls and the space formed by the side walls.
  • the device for passivating a vehicle advantageously includes a height-adjustable float which interacts with the connection for filling the space in such a way that filling with the extinguishing agent ends when a predefined fill level of the extinguishing agent inside the space is reached.
  • a height-adjustable float which interacts with the connection for filling the space in such a way that filling with the extinguishing agent ends when a predefined fill level of the extinguishing agent inside the space is reached.
  • a conventional water hose is connected to a connection of a side wall, which is locked via the internal float valve and only opens automatically when the extinguishing agent level drops.
  • At least one of the at least two side walls has a stopcock for draining an extinguishing agent located in a space defined by the at least two side walls.
  • the side walls flooded with extinguishing agent can be easily emptied.
  • the device also includes a cover element, preferably a tarpaulin, for covering the top of a space defined by the at least two side walls.
  • a cover element preferably a tarpaulin
  • This cover element can be custom-made to the dimensions of the assembled "tub" and can be, for example, a fire-retardant tarpaulin, which is slipped over all side walls when in use and thus serves as a cover. In this way, the supply of oxygen to the space defined by the side walls can be reduced.
  • the cover element is fastened by means of eyelets to fastening elements, preferably hooks, preferably provided on the side surfaces of the at least two side walls.
  • fastening elements preferably hooks
  • the cover element can have a seal arranged circumferentially on its inside. This enables a further improved space closure, through which ultimately an airless or largely airless space can be created.
  • Evacuation by means of a vacuum pump advantageously presses the inner seal against the respective side wall.
  • At least one of the at least two side walls preferably has a connection, in particular a connection with a G 1/2 inch thread, for removing air from the space defined by the at least two side walls, preferably by means of a vacuum pump.
  • a vacuum can be created in this way, so that a fire in the vehicle can be ended more quickly by suffocating it.
  • around 50 percent of the air can be removed in a defined room volume so that only a partial pressure of around 50,000 pascals remains. This air pressure corresponds to an atmospheric height of 6,000 meters, which makes a fire impossible.
  • the contaminated extinguishing agent can be sucked off, for example by means of a submersible pump, and in particular placed in a container provided for disposal and/or processing.
  • At least one of the at least two side walls has a manometer for monitoring the air pressure within the defined space.
  • the device preferably also comprises at least one essentially U-shaped profile provided on side surfaces of the at least two side walls, which profile can be brought into engagement with another end face of a side wall of the at least two side walls that can be arranged adjacent.
  • at least one essentially U-shaped profile provided on side surfaces of the at least two side walls, which profile can be brought into engagement with another end face of a side wall of the at least two side walls that can be arranged adjacent.
  • the above-mentioned object is also achieved by a method for passivating a vehicle, in particular an electric vehicle, comprising the steps: moving at least two side walls for placement around the vehicle, connecting the at least two side walls to one another, and sealing between the at least two side walls and a bottom located under the at least two side walls and/or between the at least two side walls.
  • the solution according to the invention advantageously does not require the use of a base part, which is the case with container solutions known in the prior art.
  • the device according to the invention uses the floor of the parking lot on which the vehicle to be passivated is parked.
  • the trough-like or trough-forming arrangement of the device according to the invention around the vehicle to be passivated can advantageously take place without lifting or moving the vehicle.
