Description

[0001] Securing system and method for securing a fluid container

[0002] The invention relates to a securing system for securing a fluid container according to the preamble of claim 1 and a method for securing a fluid container according to the preamble of claim 14.

[0003] Fluid containers, such as hydrogen tanks in H2 liquid systems, are used to store or transport fluids (hydrogen) and can, in practice, take on almost any dimension. They are generally cuboid or cylindrical in shape and are frequently used to store fluids. For this purpose, fluids, such as pressurized gases or liquids such as hydrogen, are fed under high pressure through a container neck into such a fluid container or tank. This causes the fluid container to expand axially / radially and increase its cross-section. The pressurized fluid container can expand or contract by up to 5% of its volume and length.

[0004] Securing systems are known in which fluid containers or pressure tanks are fixed in the area of ​​a container neck via a fixed bearing to a holding frame intended to accommodate the container. All other load-bearing elements are loosely mounted to allow axial expansion / contraction of the fluid container. There are also solutions that rely on a belt system that secures the usually cylindrically shaped fluid container to a frame with pre-tensioned belts. In both cases, considerable stress is placed on the respective connectors connecting the belt and frame, as these are subjected to enormous acceleration forces from the pressure tank, for example in the event of a vehicle accident. With the neck fastening method, the container is radially freely mounted, which could lead to undesirable radial expansion.Furthermore, depending on the design, undesirable axial / radial expansion can lead to increased stress on rigid piping systems connected to the fluid container, and directed or controlled axial expansion cannot be achieved. Therefore, securing and accommodating excessively expanding or contracting pressure tanks, such as H2 tanks, is of great importance.

[0005] It is therefore an object of the invention to overcome these and other disadvantages of the prior art and to provide an improved, durable securing system for securing an excessively expanding fluid container, which in particular supports simple and rapid assembly and securing of the fluid container to a frame construction.

[0006] Main features of the invention are defined in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 14.

[0007] In a securing system for securing a fluid container in the area of ​​a frame construction with a plurality of fastening straps for clamping the fluid container and with holding elements which can be fixed to a frame construction to form holding points, wherein the fastening straps are connected at their ends to the holding elements and the fluid container between the

[0008] According to the invention, the fastening straps are designed to clamp the fluid container radially, the ends of the fastening straps being mounted on the holding elements in an axially movable manner.

[0009] Due to the radial clamping of the fluid container via the fastening straps and the axially movable mounting of the ends of the fastening straps in the holding elements, compensation for excessive expansion or shrinkage can be achieved by means of the securing system according to the invention. This also advantageously provides both radial fixation in the radial direction of the container and axial (movable) fixation or limitation in the axial direction of the fluid container. The neck and strap fastening methods mentioned above are advantageously combined with one another, so that overall even more efficient radial / axial securing and assembly can be achieved. The inventive design of the securing device also enables precise adjustment of the axial expansion direction, thereby implementing directional expansion and enabling further connections of pipes, etc.The safety device itself and its mounting elements are protected from heavy loads. This significantly increases the longevity of the safety system.

[0010] Preferably, the fluid container can be a cylindrical hydrogen tank. Further preferably, the fastening straps can be formed by upper and lower strap halves that encompass the cylindrical container circumferentially between the retaining elements that can be fixed to the frame structure. This allows the fluid container to be radially clamped and secured in the area of ​​the frame structure. The upper and lower strap halves create a secure and uniform fastening, which is particularly effective along the circumference of the fluid container.

[0011] According to a preferred embodiment, the fastening straps can comprise at least a first and a second lower strap half and at least one upper strap half, wherein the ends of the upper and lower strap halves of the fastening straps are connected to at least two holding elements fixed to a frame structure. The holding elements can preferably be arranged opposite one another and slightly offset in height on the circumference of the fluid container and fixed to the frame structure. The two lower strap halves advantageously create load-bearing strap elements in a base area of ​​the frame structure, which greatly simplifies assembly overall because the fluid containers can be placed onto the two lower strap halves at the beginning of assembly. An additional upper strap half ensures sufficient radial tension and contributes to mechanical balance during fixation and securing.

[0012] According to another preferred alternative embodiment, a total of four retaining elements, preferably two at each longitudinal end of the fluid container, can be arranged. Further preferably, the fastening straps can comprise a total of four lower strap halves and two upper strap halves. This further increases the mechanical balance and strength of the securing device. The four retaining elements at each end of the fluid container prove to be particularly advantageous for larger container dimensions with longer longitudinal extensions.

[0013] Further preferably, the support elements can have a plurality of receiving sections for receiving the ends of the fastening straps, wherein the ends of the fastening straps are designed as strap loops. The loop shape has proven particularly advantageous for the axially movable mounting and fixation of the ends of the fastening straps to the support elements, because suitable counter-elements such as cylindrical bolts and bushings or other bodies can be passed through the strap loops at the ends. As a result, the fastening straps are mounted for axial movement, provided there is sufficient axial clearance in the area of ​​the receiving sections, and can encompass the fluid container between the support elements and apply the necessary tension forces for radial clamping.The receiving sections also simplify assembly and production because the ends of the fastening straps can be positioned more easily at the correct locations on the support element or the support elements can already be designed with corresponding elements in the receiving sections during production.

[0014] Preferably, the ends of the lower belt halves, designed as belt loops, can be narrower than the intermediate sections of the lower belt halves that encompass the fluid container. This ensures that sufficient clearance is always available for adjusting axial freedom of movement or aligned axial expansion. The narrower belt loops can, for example, be mounted for axial movement on guide bushings of the mounting element. At the same time, a sufficient width of the encompassing areas of the lower belt halves is advantageously provided, which additionally supports the attachment of the fluid container during assembly.

[0015] According to a further preferred embodiment, the holding elements can have a first and a second receiving section for receiving the ends of the lower belt halves, wherein the holding elements can have a central receiving section for receiving the ends of the upper belt half between the first and second receiving sections. The central arrangement of the upper belt loop between the two lower belt halves results in a more even absorption and distribution of the fastening and reaction forces when securing the fluid container. Overall, this significantly improves the mechanical balance when fixing and in the secured position of the fluid container. Uniform radial clamping can preferably be achieved in the region of the upper belt half, for example using tensioning means or fixing means. The frame construction is preferably open in this area.This ensures easy access to the fastening devices at all times, allowing the securing system to be released or, for example, retightened if necessary. This arrangement of the receiving sections and fastening straps allows for an axial play of approximately 45 mm at the ends of the mounting elements.

[0016] Preferably, the support elements can have one or more additional intermediate sections between the first and second receiving sections and the central receiving sections. The intermediate sections can function as spacers and advantageously provide additional stiffening for the support elements attached or fixable to the frame structure. This increases the strength values ​​and the load cycles, or the resulting loads on the support elements and the individual elements, can be easily absorbed and / or transferred into the frame structure. Preferably, the materials, as well as the strength values ​​and geometries, can be designed according to the loads. Furthermore, the support elements and all their individual components can comprise metallic materials.By arranging the additional intermediate sections, the axial play in the area of ​​the ends on the mounting elements can be reduced to approximately 1.5 mm. This means that the fastening straps are almost firmly mounted on the mounting elements and accordingly influences the axial expansion direction of the fluid container. This may be desirable in some applications. The adjustment of the axial expansion direction depends heavily on the specific environment. The relatively small freedom of movement of approximately 1.5 mm further facilitates the installation of the ends of the fastening straps on the mounting elements.

[0017] According to a further preferred embodiment, the receiving sections can be formed by individual partition walls, wherein the partition walls of the holding elements can be aligned parallel to the outer walls of the base bodies of the holding elements. This creates a secure separation between the individual receiving sections of the holding elements. The formation of the partition walls can be carried out simply by appropriate milling or other manufacturing steps. This has proven to be a particularly simple and cost-effective manufacturing variant. Furthermore, the holding elements are additionally stiffened by the parallel arrangement of the partition walls. Preferably, the intermediate sections of the holding elements, which can preferably function as spacers, can also be formed by the provision of further, intermediately positioned partition walls.

[0018] According to a further preferred embodiment, the mounting elements can comprise a scoop-shaped base body. This scoop-shaped base shape has proven particularly suitable for providing receiving sections. In combination with partition walls provided in the area of ​​the receiving sections, a sufficiently strong mounting element is created that can also withstand dynamic loads. Overall, the service life of the securing system is increased. Furthermore, the scoop shape offers an ideal attachment option for cylindrical bodies such as bolts, allowing the fastening straps to be attached and stored as desired on the mounting elements or in the receiving sections of the mounting elements.

[0019] According to another preferred embodiment, the axially movable mounting of the fastening straps on the support elements allows a range of approximately 1.5 mm or approximately 45 mm of movement of the ends of the fastening straps in the axial direction of the fluid container. This range advantageously covers the expansion or contraction range typical for H2 pressure tanks or hydrogen tanks. This allows for a targeted adjustment of the axial expansion or contraction direction for specific applications.

[0020] Preferably, the support elements may have at least one guide pin for receiving and guiding the ends of the fastening straps, wherein the guide pins extend completely through the support elements and can be secured axially to the support elements at their ends via securing elements.

[0021] According to a further preferred embodiment, the guide pins can comprise cylindrical base bodies, wherein the guide pins can be guided through the guide bushings of the holding elements and through the belt loops of the upper belt half. The use of a cylindrical guide pin and cylindrical guide bushings for receiving and supporting the belt loops has proven particularly advantageous and efficient. The guide pin is simple and cost-effective to manufacture. In addition, the contact surfaces of the belt loops facing the guide pins or the guide bushings can preferably be designed such that the securing system blocks against axial movement of the belt loops in the event of a sudden impact. The inner surfaces of the belt loops can preferably have appropriate friction values ​​to counteract sliding during sudden impacts.Further preferably, the inner surfaces can be at least partially non-slip. The guide pins and bushings can be made of metallic materials. Preferably, the belt loops of the upper belt half can directly rest against the base bodies of the guide pins and engage around them, whereas the belt loops of the lower belt halves can rest against the guide bushings of the support elements and engage around them. This advantageously creates sufficiently strong tension and uniform fixation in the area of ​​the support elements.

[0022] According to a further preferred embodiment, the holding elements can have at least two guide bushings in the region of the first and second receiving sections, wherein the guide bushings can be guided through the belt loops of the lower belt halves. The guide bushings advantageously make it possible to store or pre-install the belt loops or ends of the lower belt halves on the holding elements before they are attached to the frame structure. This significantly simplifies assembly because the fluid container can simply be placed onto the pre-fixed fastening belts or lower belt halves. As a result, the lower belt halves in the floor area advantageously act as load-bearing belts, and due to the mass of the fluid container and its own weight, the fluid container is pressed onto the lower belt halves when placed on the frame.

[0023] Preferably, the at least one upper belt half can have a separation, wherein at least one fixing element for radially clamping the fluid container can be provided in the separation region of the upper belt half. The fixing element can preferably be a threaded clamping screw. More preferably, the clamping screw can be an M12 screw, which can be tightened, preferably with a predefined assembly torque, for radial clamping of the fluid container. This method has proven to be a particularly simpler, safer, and cost-effective variant for clamping and fixing the fluid container. In addition, a desired radial tension can be set easily and in sufficiently fine adjustment steps by means of an appropriate tightening torque of the clamping screw.

[0024] Further preferably, the upper belt half can have two tensioning heads at the ends created by the separation in the separation area, wherein the tensioning heads can face each other in such a way that they move toward each other when the fixing element on the upper belt half is tightened. Further preferably, the fixing element or the M12 tensioning screw can be guided through the two tensioning heads, wherein the tensioning heads of the separated ends of the upper belt half have corresponding internal threads for interacting with the thread of the tensioning screw.

[0025] According to a further preferred embodiment, the fastening straps can be provided with damping elements, wherein the damping elements comprise a plastic and can have a corrugated profile on their side facing the fluid container. The damping elements can preferably be arranged in the region of the encompassing sections, wherein the ends with the belt loops do not have damping elements in order to be more easily connected to the holding elements and accordingly wrapped around them as a loop. The damping elements with the corrugated profiles can preferably comprise a rubber material. Due to the corrugated profiles, a greater surface pressure is advantageously created in the region of the contact surfaces of the fluid container. At the same time, the fastening and reaction forces are safely absorbed even under dynamic loads. The corrugated profile and the choice of material can support blocking in the event of a sudden impact movement and can be designed or constructed accordingly.This counteracts axial sliding of the belt loops attached to the support elements during impact movements.

[0026] According to a further aspect, the invention relates to a method for securing a fluid container, in particular an H2 pressure tank, in the region of a frame construction with a securing system, wherein the method comprises the following steps: mounting the holding elements, on which belt loops of the lower belt halves are already pre-mounted, on a frame construction of an application structure;

[0027] Locate and place the fluid container on the lower belt halves; attach the upper belt half by inserting the guide pins into the guide bushings of the support elements and passing the guide pins through the belt loops of the upper belt halves;

[0028] Axial securing of the guide pin by inserting retaining rings into designated grooves at the ends of the guide pins;

[0029] Completing the securing and assembly sequence by tightening the at least one fixing element and applying a predefined assembly torque to clamp the fluid container. The method advantageously takes into account the end user's assembly sequence, allowing the user to secure the fluid container significantly more efficiently, quickly, and easily. Further features, details, and advantages of the invention will become apparent from the wording of the claims and the following description of exemplary embodiments with reference to the drawings. They show:

[0031] Fig. 2a is a schematic representation of a first embodiment of a holding element of the security system according to the invention,

[0032] Fig. 2b is a schematic representation of a further embodiment of a holding element of the security system according to the invention,

[0033] Fig. 3a - 3d a schematic representation of a method for securing and assembling a fluid container with the securing system according to the invention.

[0034] Corresponding individual elements are provided with identical reference numerals below.

[0035] The securing system, generally designated 10 in Fig. 1, comprises, in the illustrated embodiment, a total of eight support elements 11, which are fixed to a frame structure 2 to form holding points. The support elements and frame elements fixed to the rear are not shown in Fig. 1. The securing system 10 secures two superimposed cylindrical fluid containers 1 to the frame structure 2.

[0036] For radially and axially securing the two fluid containers 1 in the region of the frame structure 2, a plurality of fastening straps 3 are provided for clamping the fluid container 1, wherein the fastening straps 3 are connected at their ends to the holding elements 11 and at least partially encompass the fluid container 1 between the holding elements 11. The fastening straps 3 are designed to radially clamp the fluid container 1 in a radial direction R, wherein the ends of the fastening straps 3 are mounted on the holding elements 11 so as to be axially movable in an axial direction A. Between two holding elements 11, which are fixed almost opposite one another on the frame structure 2, a total of three strap sections are provided, i.e. a first and a second lower belt half (not shown in Fig. 1) and at least one upper belt half 12.The ends of the upper and lower belt halves of the fastening belts 3 are connected to the support elements 11 fixed to the frame structure 2.

[0037] As can be seen, the upper belt halves 12 each have a separation, with at least one fixing element 17 being provided in the separation area of ​​the upper belt halves 12 for clamping the fluid containers 1. The fixing elements 17 are designed as threaded M 12 clamping screws and are tightened with a predefined assembly torque for radially clamping the fluid containers 1.

[0038] The upper belt halves 12 each have two tensioning heads 16 in the separation area at the ends created by the separation. The tensioning heads 16 face each other in such a way that they move toward each other when the fixing elements 17 on the upper belt halves 12 are tightened and tensioned. For this purpose, the fixing elements 17 are guided through the two tensioning heads 16, with the tensioning heads 16 of the separated ends of the upper belt halves 12 having corresponding internal threads for interacting with the thread of the fixing elements 17.

[0039] By examining Figures 2a and 2b, detailed designs of the support elements 11 and the ends of the fastening straps 3 become particularly apparent. In both embodiments shown, the support elements 11 comprise a shovel-shaped base body with outer walls.

[0040] The two exemplary embodiments shown in Fig. 2a and Fig. 2b illustrate holding elements 11 with a plurality of receiving sections 13, 13', 13" for receiving the ends of the fastening straps 3. The ends of the fastening straps 3 are all designed as belt loops 8. As can be seen, the wrapped belt loops 8 of the lower belt halves 12', 12" are narrower than the intermediate areas of the lower belt halves 12', 12" that encompass the fluid container.

[0041] The holding elements 11 comprise a first and a second receiving section 13', 13" for receiving the ends of the lower belt halves 12', 12" and a further central receiving section 13 arranged between the first and second receiving sections 13', 13" for receiving the ends of the upper belt half 12. As can be seen, the ends of the upper and lower belt halves 12, 12', 12" designed as belt loops 8 are mounted axially movably on the holding elements 11.

[0042] The axially movable mounting of the fastening straps 3 on the support elements 11 according to the embodiment shown in Fig. 2a allows a freedom of movement of the ends of the fastening straps 3 in the axial direction A of the fluid container 1 of approximately 45 mm.

[0043] The support element 11 shown in Fig. 2b additionally has two further intermediate sections 14 between the first and second receiving sections 13', 13" and the central receiving sections 13, which limit the axial freedom of movement of the ends. The axially movable mounting of the fastening straps 3 on the support elements 11 according to the embodiment shown in Fig. 2b correspondingly allows a freedom of movement of the ends of the fastening straps 3 in the axial direction A of the fluid container 1 of approximately 1.5 mm.

[0044] All receiving sections 13, 13', 13" and intermediate sections 14 of the holding elements 11 are formed by individual partition walls 7, wherein the partition walls 7 of the holding elements 11 are aligned and arranged parallel to the outer walls of the blade-shaped base body of the holding elements 11.

[0045] The holding elements 11 each have two cylindrical guide bushings 5 ​​in the region of the first and second receiving sections 13', 13", wherein the cylindrical guide bushings 5 ​​are guided through the belt loops 8 of the lower belt halves 12', 12", and the belt loops 8 are already pre-fixed to the guide bushings 5 ​​before the assembly of the fluid container 1.

[0046] The support elements 11 also each have a guide pin 4 with a cylindrical base body 4' for receiving and guiding the ends or the belt loops 8 of the fastening straps 3. The cylindrical base bodies 4' of the guide pins 4 extend completely through the support elements 11. The guide pins 4 are guided through the two guide bushings 5 ​​of the support elements 11 and through the centrally located belt loop 8 of the upper belt half 12. The guide pins 4 each have an annular groove 6' at their ends, into which a corresponding retaining ring 6 is inserted for axially securing and fixing the guide pins 4.

[0047] By adding Figures 3a to 3d, an assembly sequence of the safety system according to the invention is illustrated in more detail.

[0048] As can be seen particularly in Fig. 3a and Fig. 3b, the fastening straps 3 are additionally provided with damping elements 15. The damping elements 15 comprise a rubber material and are each provided with corrugated profiles on their side facing the fluid container. The area of ​​the strap loops 8 is not covered with the damping element 15.

[0049] As can be seen in sequence from Fig. 3a to 3d, first the mounting elements 11, to which belt loops 8 of the lower belt halves 12', 12" are already pre-mounted, are mounted on a frame structure 2 of an application structure. For assembly, fixing elements 18 are used, which are designed as fastening screws and fasten the mounting elements 11 to the frame structure 2. For this purpose, the fixing elements 18 are guided through the base body of the mounting elements 11 and into corresponding openings in the frame structure 2.

[0050] The fluid container 1 is then located and placed on the lower belt halves 12', 12" of the fastening belts 3 (see Fig. 3b).

[0051] The upper belt half 12 is then attached by inserting and passing the guide pins 4 into and through the guide bushings 5 ​​of the holding elements 11 and passing the guide pins 4 through the central belt loops 8 of the upper belt halves 12 (see Fig. 3c).

[0052] Subsequently, the guide pins 4 are axially secured by inserting the retaining ring 6 into the ring grooves 6' provided for this purpose at the ends of the guide pins 4 (see Fig. 3c).

[0053] In a final process step, the securing and assembly sequence is completed by tightening the fixing elements 17 and applying the predefined assembly torque, clamping the fluid container 1. The invention is not limited to the previously described embodiments, but can be modified in a variety of ways. In particular, the exact material combination and number of mounting elements and fastening straps can vary depending on the application.

[0054] The securing system according to the invention can generally be used for the radial and axial securing and fixation of excessively expanding / shrinking fluid containers to a frame structure. The securing system is particularly suitable for securing an H2 pressure tank or hydrogen tank.

[0055] All features and advantages arising from the claims, the description and the drawings, including design details, spatial arrangements and method steps, can be essential to the invention both individually and in a wide variety of combinations.
