Technical Field

The present disclosure relates to mounting systems, and in particular to mounting systems suitable for mounting pressurized fluid storage tanks.

Background

Compressed fluids are useful in many applications where portability is desirable. In commercial applications, high pressure tanks containing fluids may be installed on vehicles for refueling the vehicle or for transportation to an end use site, or as virtual conduits for providing fuel for power generation, mining operations, or mobile gasoline stations. Such installations require a structure that is capable of adequately protecting the tank from impacts that may damage the integrity of the tank and may cause failure of the tank. The uncontrolled release of high pressure fluids can result in property damage or personal injury when transporting fluids suitable for use as fuels. Therefore, there is a need for structural mounting solutions that can facilitate safe transport of high pressure tanks on mobile vehicles.

The present disclosure is directed to these needs and other important needs.

Disclosure of Invention

Some systems for mounting cylindrical pressurized tanks utilize one or more straps around the middle section of the tank, while others utilize collars at both ends of the cylindrical tank. By using a collar, one end of the cylindrical canister may be fixed while the other end of the cylindrical canister is mounted with the collar in a floating configuration. The floating collar may allow the canister to expand and contract as the canister is pressurized and depressurized. Furthermore, because the mounting frame system may be in a moving system that is subject to vibration, shock and other stresses during transportation, the floating collar may accommodate flexing within the overall mounting frame system that holds the tank. Some commercial installation systems use a liner in a floating configuration, where the tank collar floats within the liner. The inventors have observed that debris may enter the bushing, which results in binding or wear of the bushing. When there is a sticking inside the liner, the can collar cannot float and move freely as the can expands or contracts. As the canister collar squeezes debris out and quickly moves through the floating liner, the canister being pressurized or depressurized may stick off of the liner in a hazardous event. Over time, the wear of the liner results in the need to replace the mounting system and the ability to protect the tank before replacement is found necessary is reduced.

The present disclosure provides a mounting solution suitable for use in a collar mounted canister system. Some embodiments of the present disclosure provide systems and methods for flexibly mounting a load, wherein the load may be moved relative to a mounting location. In certain embodiments, the load may be the tank or a portion thereof, such as one end of a cylindrical tank. In some embodiments, the flexible mounting system may allow displacement of up to 0.5 inches.

The present disclosure provides a mounting plate including a mounting portion adjacent a plurality of fastening regions and a flexing portion adjacent a mounting feature. In some embodiments, the mounting plate may further comprise a plurality of flex paths formed from the mounting portion to the flex portion, wherein each of the plurality of flex paths has at least a portion with a cross-sectional area, wherein the cross-sectional areas of the plurality of flex paths are substantially consistent with each other. In some embodiments, the plurality of flexion paths may be formed by one or more cutting paths formed by a combination of circular end cuts and linear cuts. In further embodiments, the mounting plate may further comprise one or more edge scallops adjacent to the circular end cutouts. In some embodiments, multiple fastening regions may be provided at locations around the mounting feature.

The present disclosure provides a pressurized can retention structure that includes a mounting plate, a pressurized can having a can collar extending therefrom, a connection mechanism connecting a mounting feature of the mounting plate to the can collar, and a frame system connected to the mounting plate at a plurality of fastening regions of the mounting plate.

The present disclosure provides a method of mounting a tank to a frame system, the method including providing a flexure mounting plate having a mounting feature, attaching a sleeve to the mounting feature such that no relative motion occurs between the sleeve and the mounting feature, and connecting the sleeve to a tank collar on the tank such that no relative motion occurs between the sleeve and the tank collar. In certain embodiments, the method may further comprise bonding (bond) the sleeve and the can collar together. In other embodiments, the method may further comprise threadably engaging the coupling sleeve and the canister collar.

The present disclosure provides a method of mounting a tank to a frame system including providing a flexure mounting plate having a mounting feature, attaching an inflatable plug to the mounting feature such that no relative movement occurs between the inflatable plug and the mounting feature, and connecting the inflatable plug to a tank collar on the tank such that no relative movement occurs between the inflatable plug and the tank collar. In certain embodiments, the expandable plug is expanded by tightening a pin feature that pulls the expander element into a segmented portion of the expandable plug, whereby the expandable plug may be connected to the tank collar via engagement with a protrusion within the tank collar.

Detailed Description

The present disclosure may be understood more readily by reference to the following detailed description in conjunction with the accompanying drawings and examples, which form a part hereof. It is to be understood that this disclosure is not limited to the particular devices, methods, applications, conditions or parameters described and/or illustrated herein, and that the terminology used herein is for the purpose of describing particular examples by way of example only and is not intended to be limiting of the claimed disclosure. Furthermore, as used in the specification, including the appended claims, the singular forms "a," "an," and "the" include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. The term "plurality," as used herein, refers to more than one. When a range of values is expressed, another example includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another example. All ranges may be included and combined.

Fig. 1 schematically illustrates an exemplary virtual pipe trailer system 1 that may incorporate the installation system of the present disclosure. The system 1 may comprise a tractor unit 2 and a semi-trailer or trailer 3. As schematically shown in fig. 2-5, a trailer 3 may be used to contain and transport a plurality of pressurized tanks 10.

Fig. 2 shows a side view of a trailer 4, which is an embodiment of the trailer 3. The trailer 4 provides a vertically mounted cylindrical pressurized tank 10 within the frame system 5. The tank 10 may be mounted with respect to the frame system 5 with a fixed end 6 and a floating end 7. Fig. 4 shows a top view of the trailer 4, the trailer 4 may have multiple rows and columns of multiple tanks 10. The frame system 5 is schematically shown and the connections of the fluid conduits, the monitoring components and the safety components to and from the tank 10 are omitted for clarity. For clarity, fig. 2 and 4 have omitted the mounting connections in the frame system 5.

Fig. 3 and 5 show a trailer 8, which is an embodiment of the trailer 3. The trailer 8 is provided for a horizontally mounted cylindrical pressurized tank 10 within a frame system 9. The tank 10 may be mounted with a fixed end 11 and a floating end 12 relative to the frame system 9. Fig. 3 shows a side view of the trailer 8 and fig. 5 shows a top view of the trailer 8. the trailer 8 may have multiple rows and columns of multiple tanks 10. The frame system 9 is schematically shown and the connections of the fluid conduits, the monitoring components and the safety components to and from the tank 10 are omitted for clarity. For clarity, fig. 3 and 5 have omitted the mounting connections of the frame system 9.

Fig. 6 shows a schematic view of some components in an embodiment of the floating end portion 7. The tank 10 has a cylindrical end region 14 with a tank collar 15 extending therefrom. As the tank 10 expands under pressure, the tank collar 15 will extend further downwards, away from the opposite fixed end 6, not shown in fig. 6, so that the end surface 16 is displaced relative to the surface 17 of the mounting frame portion 13. The displacement distance between surface 16 and surface 17 may vary by as much as 0.5 inches depending on the pressurization level in tank 10, the temperature in the system, and the flexural state of frame system 5, which may be caused by vibration, shock, or other stress loading. The tank collar 15 extends through the gap between the mounting frame portions 13 to allow relative movement.

In order to adequately retain the tank 10 to meet safety standards and requirements, the floating end tank collar may be retained and stabilized against displacement perpendicular to the central axis of the tank 10. Fig. 7 shows a top view of a cross-sectional view through the connection plane between the can collar and the mounting system showing aspects of the liner retention system for the floating end. The mounting plate 20, which may be connected to or an integral part of the frame system, has a central opening with a bushing surface 24 disposed around an outer surface 25 of the tank collar 21. The tank collar 21 can be displaced relative to the mounting plate 20, i.e. into and out of the page as shown in figure 7. The inventors have observed that debris can become trapped in the space or gap 22 between the surfaces 24 and 25. Debris 23 may stick to surfaces 24 and 25 such that the can collars are not free to float and displace relative to each other. During pressurization and depressurization events, the adhesion between surface 24 and surface 25 may suddenly break, and dangerous dislodgement may occur. In addition, repeated movement of debris 23 trapped between surface 24 and surface 25 may wear surface 24 and surface 25. This is particularly problematic in environments where pressurized tanks 10 are used to refuel in areas where little or no infrastructure is available.

The inventors have found that it is possible to provide a mounting system without surfaces that undergo repeated relative movement between the surfaces. Embodiments of the mounting systems described herein may avoid wear due to debris and may avoid sudden untying events that may be dangerous to personnel in the surrounding area.

FIGS. 8A, 8B and 8C illustrate aspects of one embodiment of a flexure mounting plate 100 that may be used in the mounting system of the present invention. The flexure mounting plate 100 may be used for the floating ends 7 and 12 associated with the frame systems 5 and 9 described elsewhere herein. The flexure mounting plate 100 may be mounted across a void in the frame system such that a central portion of the flexure mounting plate 100 may be displaced relative to the mounting portion around the fastening region 107. A plurality of fastening areas 107 may be provided and used to secure the flexure mounting plate 100 to one or more mounting frame portions via a frame system configured to hold the pressurized tank 10. A central mounting area 106 is provided to secure the canister collar in the floating end configuration. The canister collar (not shown in fig. 8A, 8B and 8C) may be fixed against relative movement with respect to the central mounting region 106. The connection without relative movement may be provided with any connection structure that securely connects the canister collar to the flexure mounting plate 100. In this manner, the cylindrical tank 10 can expand and contract along its central axis via flexure of the flexure mounting plate. The central portion of the flexure mounting plate (i.e., the area closest to central mounting area 106) may be moved relative to the outer portions of the flexure mounting plate closest to edges 101, 102, 103, and 104. When viewing fig. 8B, the motion may be the center portion moving into and out of the page, such that surface 108 is not perfectly planar and flat. The flexmounting plate 100 may be used in the floating end 7 shown in fig. 6 by adhering the flexmounting plate 100 to the mounting frame portion 13 through the fastening area 107. In some embodiments, bolts and nuts may be used with the through hole embodiment of region 107 to secure the flex mount plate to a matching pattern of holes in the mounting frame portion 13. Suitable fasteners and surface treatments known in the art may be used to avoid disconnection due to vibration in the system.

Fig. 9A, 9B, and 9C illustrate aspects of one embodiment of a flexure mount plate 500. The flexure mounting plate 500 may be used for the floating ends 7 and 12 associated with the frame systems 5 and 9 described elsewhere herein. The flexure mounting plate 500 may be aligned with a void in the frame system that is aligned with the tank collar of the cylindrical tank 10 such that the central portion 501 of the mounting feature 520 surrounding the flexure mounting plate 500 may be displaced relative to the mounting portion around the fastening region 510. In some aspects, the flexure mounting plate 500 may be considered a variation of the flexure mounting plate 100 that allows for a more compact arrangement of the fastening regions 510 while providing the same or similar flexure between the central portion and the fastening regions. A more compact arrangement may be particularly advantageous in trailers 3/4/5 that have been designed to achieve maximum gas capacity over the volumetric range of trailer sizes. The inventors have observed that a plurality of smaller vertically mounted tanks can increase the gas capacity. In densely packed systems, the geometry of the flexure mounting plate 500 may allow for a smaller footprint than the flexure mounting plate 100 and free up ambient space within the trailer 3/4/5 for other components of the gas transport and delivery system.

The flexure mounting plate 500 may be provided with one or more cut paths 505 formed by a combination of circular end cuts 503 and linear cuts 504. One or more edge scalloped cutouts 532 may also be provided adjacent to the circular end cutout 503. The combination of the cut path 505 and the edge scallops 532 may provide one or more flex paths 530 having a substantially uniform cross-section (as shown by exemplary cross-sectional width 534 in fig. 9C). Matching of cross-sections in multiple flex paths through repeated cycles of flexing/displacement as the attached tank 10 is pressurized and depressurized may improve operating life and avoid uneven wear/stress on the flex-mount plate 500. When attached to a tank 10 that is expanding and contracting, the flexure mounting plate 500 may undergo deformation to accommodate different distances between the frame system 5 or 9 and the tank collar in the floating end 7 or 12. The mounting portion 502 closest to the fastening area 510 will be kept at a fixed distance with respect to the mounting frame portion 13 to which it is fastened. The central flexure portion 501 closest to the mounting feature 520 may be moved out of the same plane as the mounting portion 502 by a bending flexure. Fig. 10 and 11 illustrate aspects of the flexure mount plate 500 in use, in a view along section a-a of fig. 9A. In fig. 10 and 11, the connection to the tank collar of the tank 10 has been omitted for clarity and ease of viewing. In use, the canister collar will be adhered and connected to mounting feature 520 and will align with hole 205 in the center of mounting frame portion 13 of frame system 5/9. Fig. 10 shows the configuration when the tank 10 has a lower pressure and has contracted in length along its central axis so that the tank collar of the floating end has been pulled closer to the opposite fixed end. The central portion 501 may be curved away from the plane of the mounting portion 502 to provide a displacement distance "d" between the top surfaces of the portions 501/502. The fastening region 510 and the mounting portion 502 are held at a fixed distance 540 from the mounting frame portion 13 by a secure fastening connection, which may include nuts 210/212, washers and bolts or machine screws 214, with appropriate fasteners and surface treatments selected to avoid disconnection due to vibrations in the system. Fig. 11 shows the configuration when the tank 10 has a higher pressure and has expanded in length along its central axis so that the tank collar of the floating end has been pushed further away from the opposite fixed end. The displacement "d" between the top surfaces of the portions 501/502 is in the opposite direction to that shown in fig. 10.

The gap 506 along the linear cut 504 between the mounting portion 502 and the central flexure portion 501 may provide several advantageous functions. First, the gap 506 may be designed to be large enough to avoid trapping smaller debris, such as sand and gravel, than that described elsewhere herein that can stick to conventional liner systems. Such small debris may fall through the gap 506 and be removed from the gap 506 to avoid sticking and/or wear. Second, the gaps 506 may allow for some flexing between portions of the flexure mounting plate 500, as one or more gaps 506 are stretched open or pressed closed due to movement/force of the tank collar perpendicular to the central axis of the tank 10. In some cases, the vibration or acceleration/deceleration of the tank may be stopped by the gap 506 being completely closed such that the opposing walls of the gap 506 are compressed together as a hard stop to stabilize the tank 10. In some embodiments, a brush feature or skirt feature may be provided to prevent material/debris from entering gap 506.

Different connection systems may be used between the mounting plate 500 and the mounting frame portion 13 of the frame system 5/9. Any connection system and its components that provide a secure and reliable fixation between the mounting frame portion 13 and the fastening area 510 may be chosen.

In embodiments of the present disclosure, different connections may be used between the tank collar (typically a cylindrical feature) and the mounting feature 520 of the flexure mounting plate 500.

In certain embodiments, aspects of which are shown in fig. 12, can collar 301 may be provided with a protruding feature 302 extending inwardly from an inner wall of a hollow cylindrical bottom opening of can collar 301. Fig. 12 shows a cross-sectional view along section a-a of fig. 9A and 13. Protruding feature 302 mates with expandable plug 601, expandable plug 601 is expanded by tightening pin feature 603, which pin feature 603 pulls down expander element 602 to force portions of expandable plug 601 outward within the interior volume of tank collar 301. The tank collar 301 can move freely through the hole 205 in the centre of the mounting frame part 13 of the frame system 5/9. At assembly, the expandable plug 601 may be attached to the mounting feature 520 of the deflection mounting plate by using threaded features on opposite ends of the expandable plug 601 to which fastening elements (such as one or more washers 605 and nuts 604) may be attached. The expandable plug 601 may be inserted up through the opening of the tank collar 301, sliding past the protruding feature 302 in an unexpanded state. After insertion, the pin feature 603 may be tightened to pull down the expander element 602. In some embodiments, one or more adhesive materials may be used to strengthen the connection.

FIG. 13 illustrates aspects of one embodiment of an expandable plug 601. The expandable plug may be provided with a plurality of segments 610 separated by cuts that allow for expansion or contraction of the segment portions. An inclined surface 611 may be provided between the top inner edge 613 and the bottom inner edge 614, wherein the inclined surface 611 provides an expansion force as the expander element 602 (not shown in fig. 13) is pulled down along the inclined surface 611 of the segment 610. The segments 610 thereby expand outward and may extend over the protruding features 302 of the can collar 301 for engagement between the components.

In some embodiments, the connection system shown in fig. 12-13 may further include an external can collar feature (such as a nut) compressed on an outer surface of can collar 301. Compression of the outer surface may further improve the engagement between the protruding feature 302 and the plug 601. In an alternative embodiment, the plug 601 may be provided without an expansion feature and the canister collar 301 may be compressed from the outer surface to provide engagement between the components. In certain embodiments, the canister collar 301 may be provided with one or more notches or cutouts to provide greater contraction under compression of the outer surface.

In some embodiments, aspects of which are shown in fig. 14 and 15, a sleeve 700 is used to connect canister collar 301 to flexible mounting plate 500. The sleeve 700 may have an inner surface 730, the inner surface 730 being accessible through the aperture 702 at one end of the sleeve 700 having the top surface 708. Threads 705 may be provided around the outer surface of the opposite end of the sleeve 700. Two nuts 710 and 720 may be provided to engage the threads 705 and secure the sleeve 700 to the mounting feature 520 of the flexure mounting plate 500. The mounting feature 520 may be sized as a clearance hole relative to the diameter of the threads 705. The nut 710 and the nut 720 may be provided with set screws 712 and 722, and the set screws 712 and 722 may be used to improve the resistance of the connection to vibration loosening over time. In some embodiments, a surface coating, such as a thread locking compound, may also be provided along the threads 705 to maintain the position of the nuts 710 and 720. The inner lip 704 may be provided within the inner surface 730 of the sleeve 700. In some embodiments, bottom surface 320 of can collar 301 can engage inner lip 704 (a gap between bottom surface 320 and inner lip 704 is shown in fig. 15, but these elements can be flush in some embodiments). In use, the canister collar 301 may be inserted into the bore 702, thereby forming the engagement surface connection 330 along the inner surface 730 of the sleeve 700. An adhesive such as epoxy or an adhesive such as cyanoacrylate may be used to form the bond along the faying surface attachment 330. In some embodiments, a flush engagement may be provided between the top surface 708 of the sleeve 700 and the flat surface 40 on the bottom of the canister 10 around the canister collar 301.

In certain embodiments of the present disclosure, a threaded connection may be provided between the canister collar and the variation of the sleeve 700. A variation of the sleeve 700 (shown in fig. 16) may be provided with threads on the inner surface 730 of the upper portion of the sleeve 700. Corresponding threads may be provided on the outer surface 360 of the canister collar 301. Nut 760 may be provided to act as a jam nut to aid in tightening of the connection. The canister collar 301 may be provided as an adapter member that interfaces with the bottom end of the canister 10 at the interface 350, details of which are not shown here. In an alternative embodiment not shown, the sleeve 700 may be omitted and the extended tank collar 301 may be used with threads along the outer surface 360 that serve as the threads 705 to secure the nuts 710 and 720 around the flexure mounting plate 500. In some embodiments, the use of a sleeve 700 may be preferred because the sleeve is easier to replace than the adapter component tank collar 301, and a permanently installed tank 10 with a tank collar 301 may install and uninstall multiple sleeves 700 for different versions of the flex mounting plate 500 or to replace the flex mounting plate 500.

In some embodiments of the present disclosure, a flexure mount plate 1000 may be used. Some aspects of the flexure mounting plate 1000 are shown in fig. 17 and 18. The flexure mounting plate 1000 may be used for the floating ends 7 and 12 associated with the frame systems 5 and 9 described elsewhere herein. The flexure mounting plate 1000 may be aligned with a void in the frame system that is aligned with the tank collar of the cylindrical tank 10 such that the flexible portion 1001 of the mounting feature 1020 around the flexure mounting plate 1000 may be displaced relative to the mounting portion around the fastening region 1010. In some embodiments, such as the embodiment shown in fig. 17, the mounting feature 1020 may be provided closer to one end 1004 of the flexure mounting plate, while all of the fastening area 1010 may be provided at the opposite end 1003, such that the flexure mounting plate has no resistance at end 1003 to the flexure provided on the end 1004 opposite the mounting portion 1002. In certain aspects, the flexure mount plate 1000 may be considered a variation of the flexure mount plate 100 that allows the fastening region 1010 to be more compactly arranged in areas away from the gap in the frame system that is aligned with the tank collar. The flexure mounting plate 1000 is advantageous when used with a horizontally mounted tank 10 in a floating end 12 in a frame system 9 as described elsewhere herein. The flexure mounting plate 1000 may be connected to the floating end of the tank 10 along a connection 1080 similar to the connection described with reference to fig. 14-16. In some embodiments, adhesive connectors are used for the connectors 1080 as described with reference to fig. 14-15. In other embodiments, a threaded connection may be used for connection 1080, as described with reference to fig. 16. For both types of connections, the sleeve 700 or a variation thereof may be used and connected to the flexure mount plate 1000 by using nuts 710 and 720, as described above with reference to the embodiment of the sleeve 700. In other embodiments, because the sleeve 700 may be omitted, the extended tank collar 301 may be used with threads along the outer surface 360 that serve as the threads 705 to secure the nuts 710 and 720 around the flex mount plate 1000. In some embodiments, the use of a sleeve 700 may be preferred because the sleeve is easier to replace than the adapter component tank collar 301, and a permanently installed tank 10 with a tank collar 301 may install and uninstall multiple sleeves 700 for different versions of the flex mounting plate 1000 or to replace the flex mounting plate 1000.

The present disclosure provides methods of mounting a load to a frame system using the components described herein. The load may be a pressurized tank having ends that are fixed as floating ends such that expansion and contraction of the tank will move the floating ends relative to the frame system. The method may include providing a flexure mounting plate having a mounting feature, attaching a sleeve to the mounting feature such that no relative motion occurs between the sleeve and the mounting feature, and connecting the sleeve to a can collar on the can such that no relative motion occurs between the sleeve and the can collar. In some embodiments, the sleeve and the canister collar are bonded together. In other embodiments, the sleeve and the canister collar are connected by a threaded engagement. In other embodiments, the method may include providing a deflection mounting plate having a mounting feature, attaching the inflatable plug to the mounting feature such that no relative movement occurs between the inflatable plug and the mounting feature, and connecting the inflatable plug to a can collar on the can such that no relative movement occurs between the inflatable plug and the can collar. In some embodiments, the expandable plug is expanded by tightening a pin feature that pulls the expander element into a segmented portion of the expandable plug, whereby the expandable plug is connected to the tank collar via engagement with a protrusion within the tank collar.

It is appreciated that certain features of the disclosure, which are, for clarity, described herein in the context of separate examples, may also be provided in combination in a single exemplary embodiment. Conversely, various features of the disclosure that are, for brevity, described in the context of a single exemplary embodiment, may also be provided separately or in any subcombination. Further, reference to values stated in some ranges includes each and every value within that range.
