Device and method for transporting motor vehicles equipped with accumulators

Abstract

A device and a method are proposed that, even in conditions of limited storage space, such as during transport by ship, enables the detection and extinguishing of fires in vehicles equipped with accumulators, or accumulators intended for installation, by flooding with water, preferably salt water, whereby the energy of the accumulator is converted into heat heating the salt water, and at the same time the fire is contained, and an initial control of the flames is carried out by flooding the container with extinguishing gases or extinguishing foam as a rapid first measure.

Description

Battery-powered vehicles are widely coming. The variety of market creates a variety of offers with imports and exports from many national and international suppliers.The combustibility and hard to cope with task of extinguishing such vehicles is a known fact.DE 10 2021 004 894 describes a method which includes the controlled extinguishing of burning accumulators with salt water, in particular of electrically operated vehicles in open containers.Reference from DE 10 2021004 894: The invention relates to a method for controlled extinguishing or discharging of burning accumulators, in particular in electrically operated motor vehicles. In this case, agents for increasing the conductivity are added to the extinguishing or flooding water in a controlled manner, wherein a controlled short circuit converts the charge energy of the batteries into heat until the risk of reflammation is eliminated.However, it is disadvantageous in this application that the proposed solution is to be used practically only for individual fires in an environment that is readily accessible by rescue and firemen and in an open container or similar containers takes place after the first attack on the burning vehicle has taken place, a container has been created and the vehicle has been moved into the container with great effort.In the case of rail, channel, sea, river and ocean transportation, the above-mentioned method can be used. In practice, processes cannot be used. This is especially because the transport space is a tight and expensive goods and the transported vehicles must be close to one another. If an accumulator burns on a deck of a cargoer, the fire is hardly to be extinguished-and further vehicles are plugged in. Their batteries, which then burn, additionally reinforce and expand the almost indelible fire. The method described above is known. The method proposed by the application is wg. This is not applicable to heat, smoke development, lack of conditions in the movement space and lack of specialists.The object of the invention is to develop a method and a device which, even in conditions which are deficient in the space of movement, such as, for example, shipping, enables the extinguishing of individual or fewer vehicles or accumulators and seals off the fire.For this purpose, it is provided to develop a container, preferably made of light metals, which can contain at least 1 vehicle, but can preferably contain no more than four vehicles, more preferably which has a spatial size in order to be able to accommodate exactly only a single vehicle, and which is equipped with monitoring and warning technology, in particular in order to be able to detect smoke development and / or fire development and / or temperature rise in the interior of the container. Furthermore, connections are provided for the inflow of extinguishing agent, e.g. extinguishing gases, extinguishing foam, extinguishing water or salt water and the later outflow of extinguishing agent, in particular extinguishing water, wherein in the transport medium, e.g. a cargo ship, a truck, a railway transport or a conventional store, riser and distributor lines for an extinguishing agent, in particular for salt water, extinguishing water and extinguishing gases, are or are attached and the containers after being shut down are or are attached to manually or remotely operated valves arranged on the riser and distributor lines.If one of the sensors of the monitoring and warning technology arranged in the container, for example a gas, smoke, heat or optical sensor, detects an abnormality, the valve or valves automatically opens and floods the container with the extinguishing agent. This is preferably done ideally with salt water for short-circuiting the accumulator connections and then converting the energy by heating the salt extinguishing water. The steam which may possibly occur is preferably blown off through a spring-loaded valve arranged on the outer wall of the container. It can be provided that flooding with conventional water, extinguishing foam or extinguishing gas prevents, at least temporarily, dangerous and intervening flame formation until the extinguishing or salt water assumes its cooling, flame-suppressing and energy-converting task.Since flooding takes a certain time even in the case of the best pumping capacity and large pipe cross sections of the feed lines, it is preferably provided to provide the container with a connection for a flame-suppressing or extinguishing gas, for example carbon dioxide or nitrogen and / or extinguishing foam, and, in the case of a corresponding alarm, to flood the container preferably with gas and / or extinguishing foam, preferably wherein the vapor-discharging valve maintains the overpressure in the container.The alarm is ideally transmitted optically and / or acoustically on the container itself and / or by wire or "wirelessly / wireless" via communication paths, preferably W-Lan and / or Internet, to a waking or higher-order location. Preferably, a precise location monitoring with GPS tracking technology associated therewith indicates the precise location of the transport device and / or of the container.In order that the burning contents of an individually standing container or a container located on roads, rails, rivers or sea during transport can also be extinguished, it is provided that the extinguishing agent connections, in particular the water and gas connections, are adapted to the usual standards. Thus, fire weirs are capable of monitoring the fire everywhere and at any time using the proposed means of extinguishing gas, foaming or extinguishing water.It is also provided to provide the container with the usual and / or standardized devices for transport by cranes and for fastening and securing on the transport means.Since the proposed containers are preferably provided in a lightweight construction, it is provided to use a "spreader" or a container harness for loading or transshipment or for moving with gantry trucks or container bridges.Since the space on the transport means, for example car transporters and cargo ships, is very small and expensive, the proposed containers or special containers for vehicles should be as small as possible in their dimensions. Therefore, it is preferably provided to place the vehicles on pallets, to secure them and to push the pallet into the container and to push it out of the container at the arrival location. This measure makes it possible to load the pallet already in the production plant of the vehicles, wherein the pallet is accessible from all sides and the vehicles can be secured rationally, quickly and well.The pallets are preferably adapted to the inner dimensions of the container, so that the horizontal space of the container is at least predominantly, in particular completely filled. Preferably, "complete" is understood to mean that no space is left around a pallet for the personal access of a vehicle. Furthermore, vehicle dimension-adjusted devices such as load-adjusted grids or beams are attached against displacement of the load and for the attachment of damping devices such as gas-filled lifting pads or foam parts.The pallet dimensions are preferably adapted to specific groups of vehicles. Thus, different vehicles from a predetermined minimum to a maximum width and length can be stored on the respective provided pallets. It is advantageous that the intermediate space between the containers, in particular after being shut down in the transport means, is smaller than between usually parked vehicles, because in the usual case the drivers of the vehicles must have great care to avoid damage to the respectively adjacent vehicle. Containers with firmly lashinged vehicles, or vehicles which are currently stored on pallets, can be transported, lifted and displaced with a more efficient handling that is harmless for the contents, wherein the space between the containers tends towards zero, or at least is so small that this space can no longer be handled person-by-person. It is furthermore advantageous that the vehicles are safely stored even in heavy sea conditions and thus no damage of the vehicles to one another can occur.In order to enable simplified and rapid loading and unloading of the container, the container and / or the transport means is provided with a pallet displacement and transfer device for the horizontal longitudinal displacement of the pallets into and out of the container. The device consists of a device docking on the pallet to be displaced, which device is firmly connected to an endless toothed belt. This extends over two toothed disks, at least one toothed disk of which has a motor-driven, electric or pneumatic drive. If the loaded pallet is moved up to the container, the toothed belt is put into operation, the supporting plate engages the pallet and pulls it into the container. Limit switches limit the depth of retraction by shutting off the drive.In order to enable efficient, simplified and rapid loading and unloading of the container with further pallets, the container and / or the transport means is preferably provided with a pallet lifting device for lifting at least one of the pallets. Thus, at least 2 to 4 pallets can be stored and transported one above the other in a container.The pallet lifting device essentially consists of 4 lifting columns with support points for the pallet retracted as described above. When the pallet is in the desired position, the motorized drive is started and the pallet is lifted. A new pallet is retracted into the space now formed. In a space-saving manner, it is provided to bring the upper pallet into a diagonal position.The displacement and lifting device can be put into operation with temporary, externally docking electrical or pneumatic drives. This is especially in order to save dead weight during the transport of the containers.Furthermore, it is preferably provided that the vehicles are immediately placed on pallets at the manufacturer's plant after final manufacturing, secured and the pallet is placed in a "mechanical parking garage", wherein they are quickly placed into a container for further transport from there and, if necessary, the ready-to-ship container also finds a storage place in the parking garage.In order to make possible an economically viable load, it is provided to fill the containers with commercially available goods or accumulators on the return transport, wherein here too the advantages of a large pallet previously packed or jammed and provided can be advantageously used with the advantages of fire safety.Furthermore, the proposed method allows vehicles, in particular vehicles provided with electric drive and accumulators and the accumulators provided for use in these vehicles and easily flammable and combustible hazardous material to be transported as normal cargo on normal container loads, wherein the connection to an extinguishing agent supply can be ensured according to the invention.List of reference characters1 Vehicle 2 empty pallet stored on a pallet (2) ready for receiving a vehicle 3 How (1) to upper position 4 Like (1) to lower position 5 Rollers (12) to upper position 5.1 Rollers (12) with stored empty pallet (2) 6 Upper deflection roller of the lifting device 6.1 Lower deflection roller of the lifting device 7 Toothed belt or chain 8 Stored vehicle to upper position 9 Stored vehicle to lower position 10 Toothed belt deflection roller of the pallet displacement device 11 Storage rollers as pallet supportReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
