Description

Technical Field

[0001] This invention relates to the field of hydrogen energy storage technology, and in particular to a multi-bottle group solid-state hydrogen storage system. Background Technology

[0002] A multi-cylinder solid-state hydrogen storage device refers to a modular energy storage device that uses solid-state hydrogen storage materials to achieve hydrogen adsorption and storage, integrates multiple hydrogen cylinder units, and is equipped with hydrogen charging and discharging pipelines, temperature control systems, and supporting clamping structures.

[0003] Currently, most mainstream multi-cylinder solid-state hydrogen storage devices use a rigid design with a fixed-size arc-shaped support and bolts to hold the hydrogen cylinders. The holding range is only suitable for a single model of hydrogen cylinder. Due to the process differences between different hydrogen cylinder manufacturers, the actual diameter deviation of hydrogen cylinders of the same specification can reach ±3mm. Moreover, the diameter of backup hydrogen cylinders called up in emergency scenarios often fluctuates.

[0004] When existing clamping structures encounter the aforementioned dimensional deviations, they need to be adapted by adding rubber gaskets or replacing them with special arc-shaped supports. This not only increases customization costs but also extends the installation cycle. More importantly, the elastic deformation of the gaskets can cause gaps between the hydrogen cylinder and the clamping structure. Under pulsating hydrogen filling and discharging conditions, the hydrogen cylinder is prone to lateral displacement, posing a risk of collision with pipelines and causing hydrogen leakage. This severely restricts the versatility and safety of the device.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] The present invention provides at least one multi-bottle solid hydrogen storage system.

[0007] In a first aspect, embodiments of the present invention provide a multi-bottle group solid hydrogen storage system, including a body, which is composed of upper and lower parts. The upper part of the body is provided with a fixed cylinder and a movable cylinder. The circumferential surfaces of the fixed cylinder and the movable cylinder are provided with multiple clamping mechanisms with the same structure. The clamping mechanism includes a rotating plate, a connecting column, a connecting plate and an arc plate. The movable cylinder is located above the fixed cylinder. The fixed cylinder is fixedly connected to the circumferential surface of the body, and the movable cylinder is slidably connected to the circumferential surface of the body.

[0008] The fixed cylinder and the moving cylinder are fixedly connected to a plurality of evenly distributed mounting plates. The end of each pair of mounting plates is rotatably connected to the rotating plate. Each pair of rotating plates intersects each other, and the intersection of each pair of intersecting plates slides with the circumferential surface of the connecting column. The connecting column is fixedly connected to the outer ring surface of the arc plate.

[0009] Furthermore, a bottle body is installed between every two of the arc-shaped plates, and the two perpendicular sides of the connecting plate are rotatably connected to the rotating plate. A threaded rod is threaded onto the inner ring surface of the movable cylinder, and a cylinder is fixedly connected to the bottom end of the threaded rod. A rotating cylinder is rotatably connected to the inner wall of the cylinder.

[0010] In one optional embodiment, the rotating plate has through holes on both end faces centered on the connecting column, and the through holes penetrate the mounting plate and the connecting plate.

[0011] The connecting plate has an "L" shaped structure, and a silicone pad is fixedly connected to the inner ring surface of the arc plate. The silicone pad is in contact with the circumferential surface of the bottle.

[0012] In one optional embodiment, the outer wall of the body is provided with a plurality of rectangular through holes that are evenly distributed and communicate with the inner wall, and the moving cylinder moves up and down along the rectangular through holes.

[0013] In one optional embodiment, a plurality of evenly distributed rotating rods are fixedly connected to the outer annular surface of the cylinder, and a sliding groove is provided on the outer annular surface of the cylinder;

[0014] The sliding groove is located below the rotating rod, and the sliding groove is slidably connected to the surface of the rotating cylinder.

[0015] In one optional embodiment, a mounting component is fixedly connected to the top of the lower part of the body, and a plurality of evenly distributed movable blocks are slidably connected to the circumferential surface of the mounting component, wherein two of the movable blocks have insert rods attached to their outer circumferential surfaces.

[0016] In one optional embodiment, the outer circumferential surface of the rotating cylinder has two evenly distributed mounting holes, which are slidably connected to the circumferential surface of the insertion rod.

[0017] The end of the insertion rod away from the moving block is fixedly connected to a fixing plate.

[0018] In one optional embodiment, the inner ring surface of the movable block is provided with a first spring, one end of the first spring is in contact with the inner ring surface of the movable block, and the other end of the first spring is in contact with the outer ring surface of the mounting component, and the inner ring surface of the mounting hole is provided with a movable groove.

[0019] A pressing plate is fixedly connected to the circumferential surface of the insertion rod. The pressing plate slides in the moving groove. A second spring is sleeved on the circumferential surface of the insertion rod.

[0022] In one optional embodiment, an air pipe is fixedly installed at the top of the bottle, a hot and cold pipe is fitted around the circumference of the bottle, and a base plate that contacts the ground is fixedly connected to the bottom of the machine.

[0023] The beneficial effects of this invention are as follows: This invention uses a rotating rod to drive a threaded rod to move the cylinder, which in turn links the rotating plate and connecting plate to clamp the bottle with an arc-shaped plate. The silicone pad on the inner ring of the arc-shaped plate can accommodate slight deviations in bottle sizes, avoiding the limitation of only being able to accommodate a single bottle size. During limit adjustment, the insert rod, double springs, and moving block work together to form a stable mechanical limit, avoiding the safety hazards of existing devices relying on electronic components or simple snap-fits that are prone to failure under extreme conditions. The operation process is simple and efficient, saving time compared to traditional bolt fixing methods. Furthermore, the use of universal parts facilitates maintenance, and functional upgrades can be completed without replacing the entire system, solving the problems of complex maintenance and difficult modification of existing systems. Simultaneously, the retractable structure adapts to diverse scenarios such as vehicle-mounted installations, meeting the needs for flexible deployment and efficient space utilization.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] Research has found that most mainstream multi-cylinder solid hydrogen storage devices currently use a rigid design with a fixed-size arc-shaped support and bolts to hold the hydrogen cylinders. The holding range is only suitable for a single model of hydrogen cylinder. Due to the process differences between different hydrogen cylinder manufacturers, the actual diameter deviation of hydrogen cylinders of the same specification can reach ±3mm. Furthermore, the diameter of backup hydrogen cylinders used in emergency scenarios often fluctuates.

[0039] When existing clamping structures encounter the aforementioned dimensional deviations, they need to be adapted by adding rubber gaskets or replacing them with special arc-shaped supports. This not only increases customization costs but also extends the installation cycle. More importantly, the elastic deformation of the gaskets can cause gaps between the hydrogen cylinder and the clamping structure. Under pulsating hydrogen filling and discharging conditions, the hydrogen cylinder is prone to lateral displacement, posing a risk of collision with pipelines and causing hydrogen leakage. This severely restricts the versatility and safety of the device.

[0040] The shortcomings of the above solutions are the result of the inventors' practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention below should be considered as contributions made by the inventors to the present invention.

[0041] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] Based on the above research, this embodiment of the invention provides a multi-bottle group solid-state hydrogen storage system, including a body 1, which consists of upper and lower parts. The upper part of the body 1 has a fixed cylinder 2 and a movable cylinder 3 on its circumferential surface. Multiple clamping mechanisms with identical structures are fitted onto the circumferential surfaces of the fixed cylinder 2 and the movable cylinder 3. Each clamping mechanism includes a rotating plate 5, a connecting column 6, a connecting plate 7, and an arc-shaped plate 8. The movable cylinder 3 is located above the fixed cylinder 2. The fixed cylinder 2 is fixedly connected to the circumferential surface of the body 1, and the movable cylinder 3 is slidably connected to the circumferential surface of the body 1. Multiple evenly distributed mounting plates 4 are fixedly connected. The adjacent ends of every two mounting plates 4 are rotatably connected to the rotating plate 5. Every two rotating plates 5 intersect each other, and the intersection of every two plates slides on the circumferential surface of the connecting column 6. The connecting column 6 is fixedly connected to the outer ring surface of the arc plate 8. A bottle body 10 is installed between every two arc plates 8. The two perpendicular sides of the connecting plate 7 are rotatably connected to the rotating plate 5. The inner ring surface of the moving cylinder 3 is threaded with a threaded rod 11. The bottom end of the threaded rod 11 is fixedly connected to a cylinder 12. The inner wall of the cylinder 12 is rotatably connected to a rotating cylinder 14.

[0044] The rotating plate 5 has through holes on both ends centered on the connecting column 6. The through holes pass through the mounting plate 4 and the connecting plate 7. The connecting plate 7 has an "L" shaped structure. The inner ring surface of the arc plate 8 is fixedly connected to a silicone pad 9, which fits against the circumferential surface of the bottle body 10.

[0045] The outer wall of the body 1 has multiple rectangular through holes that are evenly distributed and communicate with the inner wall. The moving cylinder 3 moves up and down along the rectangular through holes.

[0046] Multiple evenly distributed rotating rods 13 are fixedly connected to the outer ring surface of the cylinder 12. A sliding groove is provided on the outer ring surface of the cylinder 12. The sliding groove is located below the rotating rods 13 and is slidably connected to the surface of the rotating cylinder 14.

[0047] During use, ensure that the moving cylinder 3 is located at the bottom limit position of the upper part of the machine body 1, the arc plate 8 is in the maximum open state, the threaded rod 11 is not locked with the inner ring thread of the moving cylinder 3, and the four bottles 10 to be installed are respectively placed between the two arc plates 8 of the four sets of clamping mechanisms. The gas pipe 24 at the top of the bottle 10 faces the outside of the machine body 1 to facilitate the subsequent connection of the hydrogen charging and discharging pipeline. The hot and cold pipes 25 pre-fitted on the circumference of the bottle 10 are not folded or squeezed.

[0048] The operator holds the rotating rod 13 on the outer ring surface of the cylinder 12 and rotates the rotating rod 13 to drive the structure. The rotating rod 13 drives the fixedly connected cylinder 12 to rotate synchronously, which in turn drives the threaded rod 11 at the top of the cylinder 12 to rotate around the central axis of the machine body 1.

[0049] Since the movable cylinder 3 is slidably connected to the machine body 1 through the rectangular through hole on the outer wall of the machine body 1, the movable cylinder 3 cannot rotate with the threaded rod 11, but can only move axially along the rectangular through hole. The threaded rod 11 engages with the inner ring thread of the movable cylinder 3, pushing the movable cylinder 3 to move upward along the rectangular through hole.

[0050] When the moving cylinder 3 moves upward, the mounting plate 4 fixed on its circumference moves upward synchronously, forming a relative displacement with the mounting plate 4 fixed on the circumference of the fixed cylinder 2. The adjacent ends of the two sets of mounting plates 4 are rotatably connected to the rotating plate 5 through the pin shaft, and the two rotating plates 5 are intersected in an "X" shape. The intersection is slidably engaged with the connecting column 6 through the sliding hole 21. The moving cylinder 3 moves upward and pushes the rotating plate 5 to rotate around the pin shaft. The intersection slides along the circumference of the connecting column 6.

[0051] The connecting plate 7 pulls the arc plate 8 closer, and the "L"-shaped connecting plate 7, which is rotatably connected to the rotating plate 5, rotates synchronously. The two vertical sides of the connecting plate 7 pull the two rotating plates 5 respectively, ensuring that the two arc plates 8 move closer to the bottle body 10 synchronously, avoiding the bottle body 10 from shifting due to unilateral force.

[0052] When the moving cylinder 3 moves upward, the distance between the two arc-shaped plates 8 decreases, and the silicone pad 9 on the inner ring surface of the arc-shaped plate 8 completely fits the circumferential surface of the bottle body 10. At this time, stop rotating the rotating rod 13 and observe whether the bottle body 10 is centered.

[0053] If the bottle body 10 is centered, continue to rotate the rotating rod 13 half a turn, and the silicone pad 9 will be squeezed and produce elastic deformation.

[0054] Check that the bottle body 10 is not misaligned, the air pipe 24 and the hot / cold pipe 25 are not deformed by compression, and the arc plate 8 fits evenly with the bottle body 10. The bottle body 10 clamping operation is completed.

[0055] Example 2

[0056] Reference Figures 1-8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the top of the lower part of the body 1 is fixedly connected to the mounting part 26, and the circumferential surface of the mounting part 26 is slidably connected to a plurality of evenly distributed moving blocks 16, wherein the outer ring surfaces of two opposite moving blocks 16 are fitted with insert rods 15.

[0057] Two evenly distributed mounting holes are provided on the outer ring surface of the rotating cylinder 14. The mounting holes are slidably connected to the circumferential surface of the insertion rod 15. A fixing plate 20 is fixedly connected to the end of the insertion rod 15 away from the moving block 16.

[0058] The inner ring surface of the movable block 16 is provided with a first spring 17. One end of the first spring 17 contacts the inner ring surface of the movable block 16, and the other end of the first spring 17 contacts the outer ring surface of the mounting part 26. The inner ring surface of the mounting hole is provided with a moving groove. The circumferential surface of the insertion rod 15 is fixedly connected with a pressing plate 18. The pressing plate 18 slides in the moving groove. The circumferential surface of the insertion rod 15 is fitted with a second spring 19. One end of the second spring 19 contacts the surface of the pressing plate 18, and the other end of the second spring 19 contacts the moving groove.

[0059] Multiple evenly distributed sliding holes 21 are provided in the sliding groove, and the sliding holes 21 are connected to the mounting holes. Multiple evenly distributed limiting grooves 22 are provided in the sliding groove, and the limiting grooves 22 are located between every two sliding holes 21. When the insertion rod 15 is pulled, the rotating rod 13 is rotated for adjustment, and the rotating cylinder 14 remains stationary. When the insertion rod 15 moves to be aligned with a certain limiting groove 22, the insertion rod 15 is released, and the position of the insertion rod 15 is maintained.

[0060] A gas tube 24 is fixedly installed at the top of the bottle body 10, and a hot and cold pipe 25 is fitted around the circumference of the bottle body 10. A base plate 23 that contacts the ground is fixedly connected to the bottom of the machine body 1.

[0061] During use, after the bottle body 10 is clamped, the insertion rod 15 passes through the mounting hole of the rotating cylinder 14 and the sliding hole 21 of the sliding groove of the cylinder 12, and one end is in contact with the moving block 16 of the mounting part 26. The second spring 19 is in a natural state, and the first spring 17 is under force.

[0062] Hold the fixing plate 20 at the end of the two insertion rods 15 with both hands and pull horizontally away from the machine body 1. The insertion rod 15 drives the extrusion plate 18 to slide along the moving groove of the mounting hole. The second spring 19 is compressed. Continue to pull until the insertion rod 15 is completely disengaged from the moving block 16 and the end of the insertion rod 15 away from the fixing plate 20 is disengaged from the sliding hole 21. At this time, the threaded rod 11 can rotate freely.

[0063] Keep the fixed plate 20 in a pulled state, finely adjust the clamping force according to the size of the bottle 10, rotate the rotating rod 13, and observe the fit between the arc plate 8 and the bottle 10.

[0064] When the moving cylinder 3 moves upward, the spacing of the arc plate 8 is adapted to the bottle body 10. The fixing plate 20 is slowly released, the second spring 19 releases its elastic force, and pushes the insertion rod 15 to move towards the mounting part 26. The insertion rod 15 enters the limiting groove 22 in the sliding groove and fits with the limiting groove 22 to form a temporary limit. At this time, you can release your hand to observe the stability of the bottle body 10.

[0065] If the clamping is stable, pull the fixing plate 20 again to disengage the insertion rod 15 from the limiting groove 22, and fine-tune the rotating rod 13 until the sliding hole 21 in the sliding groove is aligned with the axis of the insertion rod 15.

[0066] Loosen the fixing plate 20, and the second spring 19 pushes the insertion rod 15 through the sliding hole 21. One end of the insertion rod 15 presses against the moving block 16 of the mounting part 26. The moving block 16 slides outward along the circumference of the mounting part 26, and the first spring 17 is compressed. Since multiple moving blocks 16 are evenly distributed on the circumference of the mounting part 26, a radial clamping force is generated on the insertion rod 15, achieving double limit. Try rotating the rotating rod 13 to confirm that the threaded rod 11 does not rotate and the insertion rod 15 is tightly fitted with the sliding hole 21 and the moving block 16, thus completing the limit adjustment operation.

The apparatus embodiments described above are merely illustrative. For example, the division of units is only a logical functional division, and in actual implementation, there may be other division methods. Furthermore, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Based on the above-described ideal embodiments of the present invention, and through the above description, those skilled in the art can make various changes and modifications without departing from the technical spirit of the disclosed embodiments. The technical scope of the embodiments of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
