[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0033] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0034] As shown in Figure 1, this invention provides a multi-purpose solid hydrogen storage device, comprising: a hydrogen storage device body 100, which includes a hydrogen storage profile 1, an upper cover plate 2, and a lower cover plate 3. Specifically, the upper cover plate 2 is installed at the upper end of the hydrogen storage profile 1, and the lower cover plate 3 is installed at the lower end, fixing the upper and lower ends of the hydrogen storage profile 1 together. The hydrogen storage profile 1 has a gas chamber 11 and a hot water conduction chamber 12. Furthermore, the upper cover plate 2 has a vent 20, on which a gas valve 21 is installed. The gas valve 21 communicates with the gas chamber 11, allowing hydrogen to be injected into the gas chamber 11. Inside the gas chamber 11, there is a solid hydrogen storage material. When the solid hydrogen storage material absorbs hydrogen, it releases a large amount of heat. Therefore, the upper cover plate 2 also has a water inlet valve 22 and a water outlet valve 23. The water inlet valve 22 and the water outlet valve 23 are connected to the hot water chamber 12. So, cold water is injected into the hot water chamber 12 through the water inlet valve 22 and the water outlet valve 23, and the cold water carries away the heat. In this way, the solid hydrogen storage material can continuously and efficiently absorb and store hydrogen, which greatly increases the hydrogen storage capacity of the main body 100 of the hydrogen storage device. Moreover, the main body 100 of the hydrogen storage device is also easy to move and use.

[0035] Furthermore, in some embodiments of the present invention, the hot water conducting chamber 12 is located in the middle of the interior of the hydrogen storage profile 1, such that the hot water conducting chamber 12 is located in the middle of the gas chamber 11. An inner water conducting pipe 13 is installed in the hot water conducting chamber 12. Correspondingly, the upper cover plate 2 has a water inlet hole 24 and a water outlet channel 25. The water inlet hole 24 is located in the middle of the upper cover plate 2 and above the hot water conducting chamber 12. The water inlet valve 22 is installed on the water inlet hole 24 and connected to the upper end of the inner water conducting pipe 13. The water outlet channel 25 is located on one side of the water inlet hole 24. Therefore, after cold water is injected through the water inlet valve 22, the cold water enters the inner water conducting pipe 13 through the water inlet hole 24. The inner water conducting pipe 13 extends downward to the bottom of the hot water conducting chamber 12. In this way, the cold water flows upward through the bottom of the hot water conducting chamber 12 and then flows out through the water outlet channel 25 to carry away the heat.

[0036] As shown in Figures 3 and 4, further embodiments of the present invention provide a specific structure for the aforementioned water outlet channel 25. This structure includes a first water outlet 251, a middle water outlet trough 252, and a second water outlet 253. The first water outlet 251 is located on one side of the water inlet 24, the middle water outlet trough 252 is located inside the upper cover plate 2, and the second water outlet 253 is located on the upper surface of the upper cover plate 2. A water outlet valve 23 is installed on the second water outlet 253. Therefore, after the cold water carries away heat, it enters the middle water outlet trough 252 through the first water outlet 251, and then enters the second water outlet 253 and the water outlet valve 23. By carrying away heat with the cold water, the solid hydrogen storage material can continuously and efficiently absorb and store hydrogen, greatly increasing the hydrogen storage capacity of the main body 100 of the hydrogen storage device. Furthermore, the main body 100 of the hydrogen storage device is easy to move and use.

[0037] As shown in Figures 2 and 5-6, in some embodiments of the present invention, multiple heat-conducting baffles 14 are installed between the gas chamber 11 and the hot water chamber 12, thereby dividing the gas chamber 11 into multiple gas chamber sub-compartments 111. Each gas chamber sub-compartment 111 has a solid hydrogen storage material, and there is a gas chamber channel 15 between the heat-conducting baffle 14 and the upper cover plate 2. So after hydrogen is injected by the gas valve 21 on the upper cover plate 2, the hydrogen enters the multiple gas chamber sub-compartments 111 through the gas chamber channel 15, and the solid hydrogen storage material in the gas chamber sub-compartments 111 absorbs and stores the hydrogen. Furthermore, there is a sealing ring 16 between the bottom of the hot water chamber 12 and the lower cover plate 3 to prevent cold water in the hot water chamber 12 from entering the adjacent gas chamber sub-compartments 111 and affecting the hydrogen storage.

[0038] As shown in Figures 2 and 5, in some embodiments of the present invention, a plurality of first thermally conductive fins 141 are disposed on the surface of the above-mentioned thermally conductive baffle 14, so that the heat released by the hydrogen gas absorbed by the solid hydrogen storage material can be transferred through the plurality of thermally conductive baffles 14 and the first thermally conductive fins 141, and the heat is absorbed by the cold water in the hot water chamber 12.

[0039] Furthermore, multiple second heat-conducting fins 112 are installed on the inner wall of the air chamber 11. The second heat-conducting fins 112 are located between two adjacent heat-conducting baffles 14, which also facilitates the transfer of heat.

[0040] As shown in Figures 7 and 8, further, the hydrogen storage device body 100 also includes a fixed hydrogen storage base 4. This fixed hydrogen storage base 4 has multiple profile holes 41, which are used to install multiple hydrogen storage profiles 1. The fixed hydrogen storage base 4 facilitates the movement of these multiple hydrogen storage profiles 1. Specifically, the hydrogen storage profiles 1 are installed inverted in the fixed hydrogen storage base 4, increasing the safety of the hydrogen storage device body 100 and significantly increasing its overall capacity.

[0041] Furthermore, in some embodiments of the present invention, a hydrogen channel is also provided in the above-mentioned fixed hydrogen storage seat 4, and the gas valve 21 is connected to the hydrogen channel. Then, a side valve body 42 is installed on the side wall of the fixed hydrogen storage seat 4, and the side valve body 42 is connected to the hydrogen channel. So when hydrogen is needed, the side valve body 42 can be opened to release hydrogen.

[0042] Exemplary anti-bending module

[0043] As shown in Figures 9-15, in some embodiments of the present invention, the gas valve 21 and the external gas pipe 20 can be connected by a screw connection. In this case, the screw connection needs to be protected to prevent external force from pressing on the connection and causing bending, which could lead to hydrogen leakage at the connection between the gas valve 21 and the external gas pipe 20. Therefore, an anti-bending module 5 is installed between the gas valve 21 and the external gas pipe 20. This anti-bending module 5 can protect the connection between the gas valve 21 and the external gas pipe 20 and increase hydrogen safety.

[0044] Furthermore, the aforementioned anti-bending module 5 includes a first anti-bending cover 51 and a second anti-bending cover 52. Specifically, the first anti-bending cover 51 and the second anti-bending cover 52 are interlocked with each other on the air valve 21 and the external air pipe 20, thereby covering the screw connection. In addition, multiple straightening mechanisms 53 are installed inside the first anti-bending cover 51 and the second anti-bending cover 52. The multiple straightening mechanisms 53 fix the air valve 21 and the external air pipe 20 from the inside, so that the parts of the air valve 21 and the external air pipe 20 inside the anti-bending module 5 can be more stable. Therefore, when other parts of the external air pipe 20 are subjected to external pressure, it will not affect the parts inside the anti-bending module 5.

[0045] Exemplary Corrective Agencies

[0046] As shown in Figures 11-13, further, some embodiments of the present invention provide a specific structure of the above-mentioned straightening mechanism 53. The straightening mechanism 53 includes a first straightening component 54 and a second straightening component. The first straightening component 54 is installed inside the first anti-bending cover 51, and the second straightening component is installed inside the second anti-bending cover 52. Therefore, when the first anti-bending cover 51 and the second anti-bending cover 52 are fastened together, the first straightening component 54 and the second straightening component inside are also fastened together. It can be understood that the two have the same structure.

[0047] Specifically, the first straightening component 54 includes a first C-shaped straightening plate 541, two second C-shaped straightening plates 542, and two straightening frames. Here, the first C-shaped straightening plate 541 is installed inside the first anti-bending cover 51 by multiple inner rods 543. The multiple inner rods 543 are all made of elastic material and have a certain flexible support force. Therefore, when the first C-shaped straightening plate 541 in the first straightening component 54 and the first C-shaped straightening plate 541 in the second straightening component are fastened together, the air valve 21 and the external air pipe 20 can be better fixed. Furthermore, the end of the first C-shaped straightening plate 541 in the first straightening component 54 has a protrusion 5411. Correspondingly, the end of the first C-shaped straightening plate 541 in the second straightening component has a groove 5412. In this way, the connection and fixation between the two first C-shaped straightening plates 541 are increased through the cooperation between the protrusion 5411 and the groove 5412.

[0048] A straightening frame is also installed on the inner wall of the first anti-bending cover 51. Two second C-shaped straightening plates 542 are arranged between the two straightening frames. Therefore, when the straightening frames in the first straightening assembly 54 and the second straightening assembly are fastened, they move from the extended state to both sides. Then, the two second C-shaped straightening plates 542 fasten together to fix the air valve 21 and the external air pipe 20.

[0049] Exemplary straightening frame

[0050] Furthermore, some embodiments of the present invention provide a specific structure for the above-mentioned straightening frame. This straightening frame includes a guide rail seat 544. Specifically, a guide rail seat 544 and two guide rail grooves 545 are disposed on the inner wall of the first anti-bending cover 51. Here, the guide rail seat 544 is connected to the guide rail grooves 545 via a T-block 546. An inner guide groove 547 is installed inside the guide rail seat 544, and two first strip grooves 548 and second strip grooves 549 communicating with the inner guide grooves 547 are respectively provided on the guide rail seat 544. Further, in the first strip groove 548... An inclined guide rod 550 is installed inside, and the inner end of the inclined guide rod 550 is connected to the inner block 551 in the inner guide groove 547. A pointed torsion spring plate 552 is also installed between the two inner blocks 551. The pointed torsion spring plate 552 passes through the second strip groove 549 and can extend to the outside of the guide rail seat 544. The pointed torsion spring plate 552 supports the two inner blocks 551, so that the outer ends of the two inclined guide rods 550 are close to each other. The aforementioned second C-shaped straightening plate 542 is installed between the outer ends of the two inclined guide rods 550 on both sides of the first C-shaped straightening plate 541.

[0051] Therefore, when the first anti-bending cover 51 and the second anti-bending cover 52 are interlocked, the straightening frame in the first straightening assembly 54 and the straightening frame in the second straightening assembly first interlock, and the two second C-shaped straightening plates 542 are then joined together. Consequently, the inclined guide rod 550 is subjected to force and moves outward along the first strip groove 548. Then, the two inclined guide rods 550 move away from each other, and the inclined guide rod 550 moves to the outermost end of the first strip groove 548. Meanwhile, the pointed torsion spring plate 552 is pulled apart by the two inclined guide rods 550 until it retracts. The second C-shaped straightening plate 542 is retracted into the second slot 549, and the final inclined guide rod 550 moves the second C-shaped straightening plate 542 to the outer end of the first C-shaped straightening plate 541, thereby fixing the air valve 21 and the external air pipe 20. The second inner pad 5421 is also installed on the inner wall of the second C-shaped straightening plate 542, and the second inner pad 510 is also installed in the end slot of the first anti-bending cover 51 and the second anti-bending cover 52. The first inner pad 5421 and the second inner pad 510 can easily fix the air valve 21 and the external air pipe 20.

[0052] As shown in Figure 14, two first side fins 511 are further installed on the first anti-bending cover 51, and two second side fins 521 are installed on the second anti-bending cover 52. The first side fins 511 and the second side fins 521 are connected by multiple locking mechanisms 56. The multiple locking mechanisms 56 can conveniently and efficiently fix the first side fins 511 and the second side fins 521, and also facilitate subsequent disassembly. Specifically, the locking mechanism 56 of the above structure includes a telescopic lock cylinder 57 and an unlocking component 58. Here, a lock groove 513 is provided on the first side wing plate 511, and the unlocking component 58 is installed in the lock groove 513. The telescopic lock cylinder 57 is installed at the bottom of the second side wing plate 521. So after the first side wing plate 511 and the second side wing plate 521 are connected to each other, the telescopic lock cylinder 57 can be fastened in the lock groove 513. In this way, the telescopic lock cylinder 57 is fixed in the telescopic lock cylinder 57, realizing the fixation between the first side wing plate 511 and the second side wing plate 521. Then, the telescopic lock cylinder 57 can be unlocked by the unlocking component 58 to open the first side wing plate 511 and the second side wing plate 521.

[0053] Exemplary telescopic lock cylinder

[0054] As shown in Figure 14, further embodiments of the present invention provide a specific structure for the telescopic lock cylinder 57 described above. This telescopic lock cylinder 57 includes a lock cylinder sleeve 571 and a latch block 572. Specifically, the lock cylinder sleeve 571 is installed at the bottom of the second side wing plate 521, and a lock cylinder spring 573 is installed inside the lock cylinder sleeve 571. The latch block 572 is connected to the lock cylinder spring 573. Further, the unlocking component 58 includes an unlocking lever 581 and an unlocking spring 582. Specifically, the unlocking spring 582 is installed in the latch groove 513. The unlocking lever 581 is also installed in the latch groove 513 and connected to the unlocking spring 582. So when the telescopic lock cylinder 57 enters the latch groove 513, the bolt block 572 first presses the lock cylinder spring 573, and then retracts into the lock cylinder sleeve 571 to enter the latch groove 513. The unlocking spring 582 pulls the unlocking lever 581 away from the bolt block 572. The operator can move the unlocking lever 581 until it hits the bolt block 572, and then unlock the telescopic lock cylinder 57, making it easy to disassemble the first side wing 511 and the second side wing 521.

[0055] Furthermore, a guide rod 512 is installed on the first side fin 511. Correspondingly, a guide groove 522 corresponding to the guide rod 512 is provided on the second side fin 521. The guide groove 522 is conical. Specifically, the end of the guide groove 522 facing the guide rod 512 is larger than the end away from the guide rod 512. Therefore, when the first anti-bending cover 51 and the second anti-bending cover 52 are fastened together, the guide rod 512 passes into the guide groove 522. This allows the two to better align when they are fastened together, avoiding skewing that would affect the fastening effect.
