Description

Technical Field

[0001] This invention relates to the field of solid-state hydrogen storage technology, specifically to a honeycomb and truss structure solid-state hydrogen storage container. Background Technology

[0002] With the increasing demand for energy and growing environmental awareness, hydrogen energy, as a clean and efficient energy form, has broad application prospects in the fields of energy storage and transportation. However, the storage and transportation of hydrogen requires efficient, safe, and reliable containers, which is a problem that urgently needs to be solved.

[0003] Most existing hydrogen storage containers adopt cylindrical or spherical structures. These structures suffer from stress concentration and deformation when storing high-pressure hydrogen, and also pose safety hazards during transportation and use. Furthermore, in scenarios involving small-capacity, low-pressure hydrogen storage, cylindrical and spherical structures result in low hydrogen storage capacity and inefficient space utilization. Therefore, developing a novel, irregularly shaped hydrogen storage container to improve storage efficiency and reduce safety hazards is an urgent problem to be solved. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a solid-state hydrogen storage container with a honeycomb and truss structure.

[0005] The technical solution of the present invention is: a solid hydrogen storage irregular-shaped container with honeycomb and truss structure, including a square irregular-shaped container shell, a support structure composed of several trusses, and a hydrogen storage area filled inside each support structure, wherein the truss has multiple through holes.

[0006] The support structure is installed inside the container shell, and the truss is connected to the inner wall of the container shell. A safety valve is installed on the top of the container shell, and a pressure sensor and a control unit are built into the container shell. The control unit is used to monitor the pressure changes inside the container shell in real time according to the pressure sensor, and automatically adjust when the pressure is too high or too low.

[0007] The container shell is also equipped with a use valve with a shut-off function, which is used when releasing or filling hydrogen.

[0008] Description: The solid hydrogen storage container of the present invention can be used for the storage and transportation of hydrogen and for directly powering fuel cells. It can also be used for the storage and transportation of other gases. Furthermore, the solid hydrogen storage container can be manufactured using advanced manufacturing processes such as 3D printing or machining, offering multiple options for manufacturing methods. It also improves hydrogen storage efficiency and effectively reduces safety hazards.

[0009] Furthermore, the support structure consists of six quadrilateral cavities formed by alternating trusses, two pentagonal cavities, and ten triangular cavities formed with the inner wall of the container shell; the two pentagonal cavities are arranged symmetrically above and below the support structure, and a support plate is provided laterally at the connection point; each of the triangular cavities located on the left and right sides of the two pentagonal cavities is provided with a support plate.

[0010] Note: The above-mentioned symmetrical support structure design can effectively improve the pressure resistance and structural strength of the container shell, thereby improving the durability of the solid hydrogen storage irregular shape container of the present invention and enabling the solid hydrogen storage irregular shape container to meet the container strength requirements of hydrogen storage.

[0011] Furthermore, the container shell is made of stainless steel aluminum alloy or carbon fiber composite material; the truss is made of carbon fiber composite material or aluminum alloy; and the hydrogen storage area is made of solid hydrogen storage material.

[0012] Note: Using stainless steel aluminum alloy or carbon fiber composite material as the container shell material enables the container shell to have sufficient strength and corrosion resistance, thereby meeting the strength requirements of hydrogen storage containers; using carbon fiber composite material or aluminum alloy as the truss material can further improve the structural strength of the solid hydrogen storage irregular container of the present invention, and the light weight of the material does not significantly affect the overall weight of the solid hydrogen storage irregular container; solid hydrogen storage materials are one of the best hydrogen storage materials available today, with advantages such as large hydrogen storage capacity. Commonly used materials include magnesium-based hydrogen storage alloys, etc. The solid hydrogen storage materials selected in this invention are purchased from commercially available sources, but are not limited to this one type of solid hydrogen storage material.

[0013] Furthermore, each of the hydrogen storage zones is provided with an insulation layer made of copper or silver.

[0014] Note: By installing an insulation layer on the outside of the hydrogen storage area, which is made of materials with good heat transfer properties such as copper and silver, heat transfer can be effectively carried out and hydrogen leakage can be reduced. However, the choice of materials is not limited to copper and silver.

[0015] Furthermore, the support structure is detachably connected to the inner wall of the container shell via multiple pump bars, and each truss of the support structure has a cooling flow path that matches the corresponding pump bar, and the cooling flow path is filled with heat transfer oil.

[0016] Explanation: The detachable design of the support structure allows for the disassembly and replacement of the truss inside the container shell. Furthermore, the heat transfer oil in the truss is replaced by pumps, thereby enabling the heat in the middle of the support structure to be directed more quickly to the side wall of the container shell. This accelerates the heat transfer of the solid hydrogen storage device and improves its operational stability and safety.

[0017] Furthermore, the pump strips are provided in ten groups, arranged symmetrically in pairs on the left and right sides of the support structure, and in pairs on the top and bottom of the support structure; the inner wall of the container shell is provided with a groove that engages with the pump strips; each group of pump strips corresponds to a cooling flow path.

[0018] The pump bar has a snap-fit ​​on one side that engages with the support structure. A set of liquid holes is provided on both sides of the inner wall at both ends of the snap-fit, which are connected to the liquid inlet of the cooling flow path. The pump bar is hollow inside, and a piston bar is slidably sealed inside the pump bar between the liquid holes at both ends. The length of the piston bar is greater than the length of a set of liquid holes.

[0019] An electric push rod is provided on one side inside the pump bar, and the output end of the electric push rod is fixedly connected to one end of the piston bar.

[0020] Note: The pump bar structure described above allows the reciprocating motion of the electric push rod to move the heat transfer oil in the two cooling flow paths. Furthermore, this snap-fit ​​structure design allows the pump bar to be retained, with maintenance and replacement only required for the truss. Modular construction can significantly reduce the cost of later maintenance.

[0021] Furthermore, a snap-fit ​​shaft is rotatably provided on both the upper and lower sides of the pump bar. One end of the snap-fit ​​shaft extends out of the pump bar and is threaded. Multiple snap-fit ​​blocks connected by sliding grooves and springs are provided at equal intervals on the snap-fit ​​shaft. A strip-shaped groove is provided in the groove, and the inner wall of the strip-shaped groove is provided with a threaded countersunk hole that is threadedly connected to the snap-fit ​​shaft. The strip-shaped groove has a snap-fit ​​groove that is paired with the multiple snap-fit ​​blocks to lock the snap-fit ​​shaft after it rotates.

[0022] Explanation: The snap-fit ​​shaft design makes it easier to install the pump bar in the settling tank. Simply push the pump bar horizontally along the notch on one side of the settling tank until it can no longer be pushed. Then, the threaded part of the snap-fit ​​shaft engages with the threaded countersunk hole, causing the snap-fit ​​shaft to rotate automatically by 90°. This automatically snaps the pump bar into place with the settling tank, further improving the stability of the pump bar and the settling tank.

[0023] Furthermore, each side of the piston strip is provided with a push plate, and the two push plates are fixedly connected by a replenishment tube. The replenishment tube passes laterally through the tube hole provided on the piston strip. The replenishment tube is provided with an outlet hole and an inlet hole that communicate with the internal pipeline of the replenishment tube. The piston strip is hollow inside and filled with heat-conducting oil antioxidant. The tube hole is provided with a replenishment hole that allows the replenishment tube to slide and be misaligned.

[0024] A first liquid bladder is provided between the push plate and the side wall of the piston strip, and a second liquid bladder is provided inside the piston strip. The first liquid bladder and the second liquid bladder are connected by a pipe, and a one-way valve is built into the pipe. The first liquid bladder is provided with a liquid replenishment port with a one-way valve.

[0025] Explanation: By setting push plates, based on the pump bar, the reciprocating motion of the piston bar allows the two push plates and the replenishment pipe to reciprocate left and right relative to the piston bar under the extrusion pressure of the heat transfer oil. This periodically releases small amounts of antioxidants into the heat transfer oil, thus maintaining the heat transfer oil's thermal conductivity at a high efficiency for a long time. Further optimization of the pump bar structure enables automatic addition of antioxidants to the heat transfer oil without the need for additional drive.

[0026] The beneficial effects of this invention are:

[0027] (1) The solid hydrogen storage container provided by the present invention can be used for the storage and transportation of hydrogen and for direct power supply to fuel cells. It can also be used for the storage and transportation of other gases. It has a honeycomb and truss structure, which can improve the strength and rigidity of the solid hydrogen storage container. It has a pressure resistance of 4MPa, which improves the hydrogen storage efficiency and effectively reduces safety hazards.

[0028] (2) The support structure provided by the present invention utilizes a detachable design to disassemble and replace the truss inside the container shell, and replaces the heat transfer oil in the truss through the pump bar, thereby directing the heat in the middle of the support structure to the side wall of the container shell more quickly, accelerating the heat transfer of the solid hydrogen storage device, and improving the stability and safety of the solid hydrogen storage device.

[0029] (3) The pump bar provided by the present invention utilizes the snap-fit ​​shaft to make it easier to install the pump bar in the settling tank. Simply push the pump bar horizontally along the notch on one side of the settling tank until it can no longer be pushed, and the pump bar and the settling tank will be automatically snapped together, thereby further improving the stability of the pump bar and the settling tank.

[0030] (4) The pump bar provided by the present invention utilizes the push plate to enable the piston bar to periodically release a small amount of heat transfer oil antioxidant during reciprocating motion, thereby keeping the heat transfer oil in a high-efficiency state for a long time.

Detailed Implementation

[0051] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0052] Example 1

[0053] like Figures 1-4 As shown, a solid hydrogen storage container with a honeycomb and truss structure includes a square-shaped container shell 1, a support structure 2 composed of several trusses 21, and a hydrogen storage area 3 filled inside each support structure 2. The trusses 21 have multiple through holes 22.

[0054] It is understandable that square irregular shapes refer to... Figure 1 The square-shaped structure shown has rounded corners on all four sides, and its front side has a recess for holding a handle that can lift the solid hydrogen storage device.

[0055] like Figure 2-4 As shown, the support structure 2 is disposed inside the container shell 1, and the truss 21 is welded to the inner wall of the container shell 1. The support structure 2 consists of six quadrilateral cavities 23 formed by alternating arrangement of several trusses 21, two pentagonal cavities 24, and ten triangular cavities 25 formed with the inner wall of the container shell 1. The two pentagonal cavities 24 are arranged symmetrically above and below the support structure 2, and a support plate 26 is provided laterally at the connection point. Each of the triangular cavities 25 located on the left and right sides of the two pentagonal cavities 24 is provided with a support plate 26.

[0056] It is understandable that, strictly speaking, the support plate 26 of the triangular cavity 25 also makes the two triangular cavities 25 on the left and right sides actually quadrilaterals. However, for the sake of convenience, the width of the support plate 26 here is less than half the width of the support plate 26 in the middle. Therefore, the influence of the support plate 26 here on the description of the cavity structure is ignored.

[0057] A safety valve is provided on the top of the container shell 1, and a pressure sensor and a control unit are built into the container shell 1. The control unit is used to monitor the pressure changes inside the container shell 1 in real time according to the pressure sensor, and automatically adjust when the pressure is too high or too low.

[0058] The container shell 1 is also equipped with a shut-off valve for use when releasing or filling hydrogen; the container shell 1 is made of commercially available stainless steel; the truss 21 is made of aluminum alloy; the hydrogen storage area 3 is made of commercially available solid hydrogen storage material; each of the hydrogen storage areas 3 is provided with an insulation layer made of copper; the pressure sensor is commercially available, and the control unit is a commercially available PLC controller.

[0059] Example 2

[0060] The difference between this embodiment and Embodiment 1 is that, Figure 5 , Figure 6 As shown, the support structure 2 is detachably connected to the inner wall of the container shell 1 via multiple pump bars 4, and each truss 21 of the support structure 2 has a cooling flow path that matches the corresponding pump bar 4 (not shown in the figure). The cooling flow path is filled with heat transfer oil, which is selected from commercially available heat transfer oil.

[0061] like Figure 6 As shown, there are ten pump bars 4, arranged in three groups symmetrically on the left and right sides of the support structure 2, and in two groups symmetrically on the top and bottom of the support structure 2; the inner wall of the container shell 1 is provided with a groove 11 that engages with the pump bars 4; each group of pump bars 4 corresponds to a cooling flow path;

[0062] like Figures 7-9 As shown, the pump bar 4 has a snap-fit ​​41 on one side that engages with the support structure 2. A set of liquid holes 42 are provided on both sides of the inner wall at both ends of the snap-fit ​​41, which are connected to the liquid inlet 5 of the cooling flow path. The pump bar 4 is hollow inside, and a piston bar 43 is slidably sealed inside the pump bar 4 between the two liquid holes 42. The length of the piston bar 43 is longer than the length of the set of liquid holes 42 by the diameter of one liquid hole 42. An electric push rod is provided on one side inside the pump bar 4, and the output end of the electric push rod is fixedly connected to one end of the piston bar 43.

[0063] The installation method of the above-mentioned support structure and pump bar:

[0064] Ten pump bars 4 are inserted one by one into the mating edges of each truss 21 of the support structure 2, and each pump bar 4 and truss 21 are sealed to prevent the inlet 5 and liquid hole 42 from leaking heat transfer oil and affecting the hydrogen storage performance of the solid hydrogen storage device.

[0065] Then, each pump bar 4 is inserted into its corresponding sink 11 through the notch in the sink 11, thus completing the installation of the support structure 2 and the pump bar 4 inside the container shell 1.

[0066] By activating each electric push rod, the two piston strips 43 in the same cooling flow path move in opposite directions, thereby causing the heat transfer oil in the cooling flow path to flow under the alternating push and pull of the two piston strips 43, accelerating the heat transfer from the middle of the support structure 2 to the side wall of the container shell 1, thus speeding up the heat transfer effect.

[0067] It is understandable that the electric linear actuator can execute programs through an external PLC controller to perform the aforementioned motion; the electric linear actuator can be powered by an external power supply.

[0068] Example 3

[0069] The difference between this embodiment and embodiment 2 is that, Figures 10-14 As shown, a snap-fit ​​shaft 6 is rotatably provided on both the upper and lower sides of the pump bar 4. One end of the snap-fit ​​shaft 6 extends out of the pump bar 4 and is threaded. Multiple snap-fit ​​blocks 61 are provided at equal intervals on the snap-fit ​​shaft 6 and are connected by sliding grooves and springs. A strip groove 12 is provided in the recess 11, and the inner wall of the strip groove 12 is provided with a threaded countersunk hole 13 that is threadedly connected to the snap-fit ​​shaft 6. The strip groove 12 has a snap-fit ​​groove 14 that is used to lock the snap-fit ​​shaft 6 after it rotates, one by one with the multiple snap-fit ​​blocks 61.

[0070] The above pump bars are used as follows:

[0071] Based on the working method of Example 2, when each pump bar 4 is inserted into its corresponding countersunk groove 11 through the notch of the countersunk groove 11, after the pump bar 4 is pushed to the engagement of the thread of the locking shaft 6 with the thread countersunk hole 13, the locking shaft 6 rotates 90° under the transmission action of the two, during which the spring of the locking block 61 stores energy. When the pump bar 4 is pushed completely, the locking block 61 moves completely to the corresponding locking groove 14, so that each locking block 61 on the locking shaft 6 returns to its original position under the action of the spring and engages with the locking groove 14, thereby completing the stable engagement of the pump bar 4 and the countersunk groove 11.

[0072] When it is necessary to remove the pump bar 4 from the settling tank 11, simply rotate the other end of the locking shaft 6 corresponding to the thread using a flathead screwdriver to reverse it by 90°, and the pump bar 4 can be pulled out of the settling tank 11.

[0073] Example 4

[0074] The difference between this embodiment and embodiment 2 is that, Figures 15-19As shown, each side of the piston strip 43 is provided with a push plate 45, and the two push plates 45 are fixedly connected by a replenishment tube 46. The replenishment tube 46 passes laterally through the tube hole provided on the piston strip 43. The replenishment tube 46 is provided with an outlet hole 461 and an inlet hole 462 that communicate with the internal pipeline of the replenishment tube 46. The piston strip 43 is hollow inside and filled with heat transfer oil antioxidant. The heat transfer oil antioxidant is selected from commercially available heat transfer oil antioxidants and is liquid. The tube hole is provided with a replenishment hole 47 that allows the replenishment tube to slide and be misaligned. A first liquid bladder 48 is provided between the push plate 45 and the side wall of the piston strip 43. A second liquid bladder 49 is provided inside the piston strip 43. The first liquid bladder 48 and the second liquid bladder 49 are connected by a pipe, and the pipe is equipped with a one-way valve. The first liquid bladder 48 is provided with a replenishment port with a one-way valve.

[0075] The above pump bars are used as follows:

[0076] Based on the working method of Example 2, during the reciprocating motion of the piston strip 43, the push plates 45 on both sides of the piston strip 43 are pushed alternately, so that one push plate 45 is squeezed by the first liquid bladder 48, and the liquid outlet 461 of the replenishment tube 46 corresponding to the other push plate 45 is exposed. Under the pressure of the second liquid bladder 49, the heat transfer oil antioxidant in the piston strip 43 is discharged through the replenishment hole 47 and the replenishment tube 46, and then discharged through the liquid outlet 461.

[0077] By repeating the above process, the heat-conducting oil antioxidant in the piston strip 43 can be released by the action of the two push plates 45.

[0078] Understandably, another push plate can be provided. In this way, compared with the above solution, the piston strip 43 can only release the heat transfer oil antioxidant when it moves in one direction. This can be adjusted according to actual usage requirements. At the same time, the amount of heat transfer oil antioxidant released from the piston strip 43 at one time can be controlled by the capacity of the first liquid bladder 48.
