Definitions

  • the invention relates to a storage device for compressed gas.
  • the compressed gas can be hydrogen or natural gas, for example, which is used as fuel in a fuel cell system or in an internal combustion engine.
  • the invention relates to a vehicle with a storage device according to the invention.
  • Safety solenoid valves are therefore used to securely close pressurized gas containers, which are closed when de-energized so that gas escape is reliably avoided even in the event of a fault. It may be required by law that such a safety solenoid valve (“Shut-Off-Valve”) be present for each pressurized gas container and must be fitted directly on or in the container. Depending on the number of containers, the number of valves can thus increase rapidly.
  • a storage device for compressed gas with a plurality of compressed gas containers which are each connected to a common collection volume via a tank valve and a line element.
  • the collection volume which can also be referred to as a "rail", reduces the piping work.
  • the collection volume is expanded to the effect that valve devices, which were previously present in the gas supply line or the gas discharge line are integrated into the collection volume. This reduces the number of interfaces, which is an advantage with regard to the sealing problem.
  • the integrated valve devices are preferably a non-return valve in the area of a gas supply line and a shut-off valve in the area of a gas discharge line.
  • valve devices integrated in the collection volume can be used to seal off the surrounding lines.
  • the present invention is based on the object of further developing a storage device of the type mentioned above in such a way that it satisfies increased safety requirements, for example to enable the use of pressurized gas containers whose nominal pressure is 900 bar or more.
  • the proposed storage device for compressed gas for example for hydrogen or natural gas, comprises a storage line and at least one compressed gas tank connected to the storage line.
  • the connection is realized via a socket-like connection piece of the storage line and a socket-like connection piece of the compressed gas tank, which interact to form a joint.
  • connection of the compressed gas tank to the storage line which is designed as a joint, allows tolerances in the connection area due to manufacturing and/or assembly to be compensated for, so that a high degree of tightness of the connection is ensured. In particular, misalignment and/or concentricity problems can be eliminated via the joint.
  • connection satisfies increased safety requirements, so that the storage device is suitable for nominal pressures of up to 900 bar or even more.
  • the socket-like connection piece of the storage line and the socket-like connection piece of the compressed gas tank preferably each have a spherically or conically shaped connection geometry.
  • a spherically or conically shaped connection geometry For example, two spherically shaped connection geometries or one spherical and one conically shaped connection geometry can interact to form a joint.
  • connection geometries In the case of two spherically shaped connection geometries, these are of opposite design, that is to say that one geometry is concave and the other geometry is convex, so that they interact to form a ball and socket joint.
  • the concave geometry is formed on the connection piece of the storage line and the convex geometry on the connection piece of the compressed gas tank, resulting in an optimized flow geometry in the flow direction of the gas from the compressed gas tank into the storage line.
  • the (concave) conical geometry forms a seat for the (convex) spherical geometry.
  • the contact area is reduced to a circumferential contact line, which enables self-centering and also has a high sealing force in the contact area. Additional sealing means, such as a sealing ring, can therefore be dispensed with.
  • the convex geometry is advantageously formed on the connection piece of the compressed gas tank and the concave geometry on the connection piece of the accumulator line.
  • a sealing ring be integrated into the connection geometry of the connection piece of the storage line, which sealing ring bears against the connection geometry of the connection piece of the compressed gas tank under axial prestress.
  • the two connection geometries are each spherically shaped, so that the contact area is not reduced to a circumferential contact line.
  • vibrations can be compensated with the help of the sealing ring to which memory devices for mobile applications in particular are exposed, for example when driving over uneven terrain.
  • the sealing ring converts the kinetic energy of the vibrations into deformation energy, so that damping is achieved.
  • the compressed gas tank is preferably held on the storage line by means of a union nut.
  • An axial force can be generated via the mounting by means of the union nut, which ensures the sealing contact between the two connecting pieces and causes a sealing force in the sealing contact. If the sealing contact is made via a sealing ring, the necessary axial prestressing force can be generated with the aid of the union nut, by means of which the sealing ring rests on the connection piece of the compressed gas tank.
  • the union nut is preferably connected to the connection piece of the storage line or the connection piece of the compressed gas tank via a screw connection and is supported in the axial direction on an annular collar of the respective other connection piece.
  • the compressed gas tank can be easily assembled and disassembled via the screw connection. To do this, simply loosen the screw connection between the union nut and the storage line or the compressed gas tank.
  • the support of the union nut on the annular collar of the respective other connection piece does not have to meet any tightness requirements, since the functions of holding and sealing are separate in the present case.
  • the seal is achieved via the connection geometries of the two connection pieces or an intermediate sealing ring, so that the union nut only has to take over the function of the holder.
  • the annular collar on which the union nut is supported can be formed by the respective connection piece, which is the connection piece that is not screwed to the union nut, or by a separate ring. If the latter is the case, the separate ring is preferably fastened to the corresponding connecting piece with the aid of a locking ring, so that the position of the ring or annular collar in relation to the connecting piece is fixed.
  • the union nut is supported axially via a spherically or conically shaped support geometry on a spherically or conically shaped support geometry of the annular collar. This means that the union nut and the annular collar are also connected in an articulated manner.
  • the union nut surrounds the connection piece that has or forms the annular collar, forming an annular gap.
  • the annular gap ensures the free space that the union nut needs to move relative to the annular collar of the respective connection piece.
  • several compressed gas tanks are connected to the storage line.
  • the connection is the same for all compressed gas tanks, so that all compressed gas tanks are connected to the storage line via an articulated connection.
  • the multiple compressed gas tanks are preferably arranged in a row, so that a space-saving arrangement is created.
  • the overall height of the storage device can be kept low as a result of the arrangement in a row. This proves to be an advantage above all in mobile applications, since the storage device is usually arranged underneath the chassis of a vehicle, so that the overall height is limited.
  • Compressed gas bottles in particular come into consideration as compressed gas containers. In this case, a bottleneck or a nozzle-like component connected to the bottleneck can serve as the connection piece.
  • the multiple compressed gas tanks or compressed gas cylinders are mounted on a frame-like structure.
  • the entire storage device can be attached to the chassis of a vehicle via the frame-like structure, preferably underneath the chassis.
  • the at least one compressed gas tank is advantageously mounted in the frame-like structure via a fixed bearing and a floating bearing.
  • the floating bearing allows the compressed gas tank to undergo thermally induced changes in length without constraints or tension. As a result, the robustness of the memory device can be further increased.
  • the loose bearing is preferably arranged closer to the storage line than the fixed bearing. Since the connection of the compressed gas tank to the storage line is designed as a joint, the changes in length and/or movements of the compressed gas tank relative to the floating bearing in the area of the connection can be compensated.
  • the storage line is connected to the frame-like structure and the connection allows relative movements of the storage line with respect to the frame-like structure, in particular to compensate for changes in length of the at least one compressed gas tank.
  • the connection can be a clamp or clip connection, for example.
  • a number of attachment points can be provided on the frame-like structure, in the area in which the storage line is attached by means of clamps or clips.
  • the connection should in particular allow movements of the storage line in the direction of the longitudinal axis of the at least one compressed gas tank.
  • the storage device according to the invention is preferably used in a mobile application, a vehicle with a storage device according to the invention is also proposed.
  • the compressed gas can in particular be hydrogen for operating a fuel cell system or an internal combustion engine.
  • the compressed gas can be natural gas, which is stored on board the vehicle for operating an internal combustion engine with the aid of the device according to the invention.
  • the storage device shown schematically comprises a frame-like structure 16 which encloses a storage line 1 and a plurality of compressed gas tanks 2 connected to the storage line 1 .
  • a frame-like structure 16 which encloses a storage line 1 and a plurality of compressed gas tanks 2 connected to the storage line 1 .
  • five pressurized gas containers 2 arranged in a row are shown, which are aligned approximately parallel to one another. Because of manufacturing and/or assembly-related tolerances, there are axial displacements that are compensated for in the present case by tilting the respective compressed gas tank 2 .
  • the pressurized gas tanks 2 can be positioned at an angle to one another (see Fig. 1a )) and/or at different altitudes ( Fig. 1b )) come to rest.
  • connection of the compressed gas tank 2 to the storage line 1 is in each case via a socket-like connection piece 3 of the storage line 1 and a socket-like connection piece 4 of the respective compressed gas tank 2 manufactured. Possible embodiments are based on the Figures 2 and 3 described.
  • connection piece 3 which is part of the storage line 1 .
  • the connection piece 3 has a conically shaped connection geometry 6 which serves as a seat for a spherically shaped connection geometry 7 of a second socket-like connection piece 4 which is part of a compressed gas tank 2 . Because of their connection geometries 6 , 7 , the two connection pieces 3 , 4 work together to form a joint 5 .
  • the joint 5 can thus tilt the Compressed gas tank 2 can be achieved in order to compensate for manufacturing and / or assembly-related tolerances.
  • connection geometries 6, 7 The contact between the two connection geometries 6, 7 is reduced to a circumferential contact line, so that when the compressed gas tank 2 is assembled, the compressed gas tank 2 is self-centering. This means that the compressed gas tank 2 aligns itself in relation to the connection geometry 6 of the connection piece 3 of the storage line 1 . At the same time, a high sealing force can be achieved over the linear contact area.
  • the sealing force is generated with the aid of a union nut 9 which is connected on the one hand to the connection piece 4 of the compressed gas tank 2 via a screw connection 10 and on the other hand is axially supported on an annular collar 11 of the connection piece 3 of the storage line 1 .
  • the annular collar 11 is designed as a separate ring, which is fastened to the connection piece 3 of the storage line 1 by means of a locking ring 12 .
  • the sealing force can be adjusted via the screwing depth of the connecting piece 4 of the compressed gas tank 2 into the union nut 9 .
  • the union nut 9 has a first support geometry 13 which also forms a joint with a second support geometry 14 formed on the annular collar 11.
  • An annular gap 15 between the union nut 9 and the connection piece 3 of the storage line 1 provides the necessary free space so that the compressed gas tank 2 together with the union nut 9 can be aligned with respect to the connection piece 3 of the storage line 1 .
  • connection pieces 3, 4 each have a spherically shaped connection geometry 6, 7, so that a flat contact area is created.
  • the sealing force is less high, so that a sealing ring 8 is additionally integrated into the connection geometry 6 of the connection piece 3 of the storage line 1 to ensure tightness.
  • the connection geometry 6 has a shoulder 17 in the form of a Depression into which the sealing ring 8 is inserted.
  • the embodiment corresponds to 3 the the 2 , so that on the description of the 2 is referenced.
  • the union nut 9 for holding the compressed gas tank 2 is screwed to the connection piece 3 of the storage line 1 via a screw connection 10 and is axially supported on an annular collar 11 of the connection piece 4 of the compressed gas tank 2 .
  • the annular collar 11 is not formed by the connection piece 4 itself, but by a separate ring which is fixed via a locking ring 12 on the connection piece 4 of the compressed gas tank 2 .
  • the annular collar 11 has a support geometry 14 which interacts with a support geometry 13 of the union nut 9 to form a joint.
  • connection piece 4 of the compressed gas tank 2 and the union nut 9 creates the necessary free space in order to be able to pivot the compressed gas tank 2 relative to the connection piece 3 of the storage line 1 to at least a small extent. This free space is completely sufficient for tolerance compensation.
  • FIG 5 shows a fully assembled storage device according to the invention, with the storage line 1 not being visible, however, since it is covered by the frame-like structure 16.
  • the storage line 1 not being visible, however, since it is covered by the frame-like structure 16.
  • several pressurized gas tanks 2 can be seen, which are held parallel to one another in the frame-like structure 16 via a fixed bearing 18 and a floating bearing 19 .
  • the number of compressed gas tanks 2 is not limited to three, but can be expanded as desired.
  • the fixed bearing 18 has a lower part 18.1 and an upper part 18.2.
  • the lower part 18.1 which is formed by a web-like structure, causes in particular a lateral support of the compressed gas tank 2. In this way, vibrations can be absorbed.
  • raised sections of the lower part 18.1 prevent the pressurized gas containers 2 from touching one another.
  • the upper part 18.2 of the fixed bearing 18 presses the compressed gas tank 2 downwards, i.e. against the lower part 18.1 of the fixed bearing 18.
  • the loose bearing 19 also has a lower part 19.1 and an upper part 19.2, with the upper part 19.2 not exerting any pressure on the compressed gas tank 2.
  • the upper part 19.2 preferably has no contact at all with the pressurized gas containers 2, so that these can move relative to the loose bearing 19, in particular in the direction of their longitudinal axis.
  • the lower part 19.1 of the loose bearing 19 can be designed analogously to the lower part 18.1 of the fixed bearing 18 in order to prevent the compressed gas tank 2 from hitting one another in the event of vibration.
  • the storage line 1 can be held on the frame-like structure 16 via clamp connections 20, the clamp connections 20 allowing movements of the storage line 1 relative to the frame-like structure 16 in the direction of the longitudinal axes of the compressed gas tanks 2.
