[0035] The following reference Figures 1 to 3 This application describes a modularly assembled solid-state hydrogen storage system according to some embodiments.
[0036] See Figures 1 to 3As shown, an embodiment of this application provides a modularly assembled solid hydrogen storage system, including: a tank 1, two thermal management and protection components 2, a support member 3, a storage container, and a pump body; wherein, the storage container is disposed on the support member 3; the two thermal management and protection components 2 are respectively disposed on opposite sides of the support member 3 and the tank 1; each thermal management and protection component 2 includes a heat insulation cover 21, a heat exchange pipe 22, a first conveying pipe 23, a second conveying pipe 24, a first driving member 25, and a connecting member 26;
[0037] The first driving component 25 is disposed on the supporting component 3, and the driving end of the first driving component 25 is connected to the heat insulation cover 21 through the connecting component 26; the heat exchange pipe 22 is disposed inside the heat insulation cover 21, and the first driving component 25 can drive the heat insulation cover 21 together with the heat exchange pipe 22 to move toward or away from the tank 1, so that the two heat insulation covers 21 can be joined together and covered on the outside of the tank 1.
[0038] One end of the first conveying pipe 23 is connected to the inlet end of the heat exchange pipe 22, and the other end of the first conveying pipe 23 is connected to the storage container via the pump body; one end of the first conveying pipe 23 is connected to the outlet end of the heat exchange pipe 22, and the other end of the first conveying pipe 23 is connected to the storage container via the pump body.
[0039] Based on the structure described above, the installation and disassembly process of the thermal management module and tank 1 in the modular solid-state hydrogen storage system provided in this application is as follows:
[0040] First, the two first driving components 25 contract, causing the two heat shields 21 to close under the control of the first driving components 25, thus finally fitting onto the outside of the tank body 1, achieving rapid assembly of the thermal management module and the tank body 1. In use, cold or hot water is supplied through the first conveying pipe 23, allowing the heat shields 21 to work with the heat exchange tubes to meet the cooling requirements of the tank body 1 during hydrogen filling and to provide heat during hydrogen release to promote hydrogen desorption. Moreover, when the tank body 1 needs to be treated or the heat exchange tubes need to be maintained, the first driving components 25 can be extended, thereby driving the two heat shields 21 to open under the control of the first driving components 25, thus releasing the tank body 1, and achieving rapid disassembly of the thermal management module and the tank body 1. The above operation is simple, convenient, time-saving, labor-saving, and easier to maintain.
[0041] As can be seen, in the modular solid hydrogen storage system provided by this application, the tank 1 and the special management module are set up independently, and can be quickly assembled and disassembled, which is extremely convenient for later maintenance, saves labor, and helps to reduce maintenance costs.
[0042] In this embodiment, preferably, as follows: Figure 1As shown, the modularly assembled solid hydrogen storage system also includes a limiting telescopic rod 4, one end of which is connected to the support member 3, and the other end of which is connected to the connecting member 26.
[0043] Furthermore, preferably, in this embodiment, the limiting telescopic rod 4 is a two-stage telescopic rod, that is, it includes a first pipe and a second pipe, with the first pipe positioned closer to the connecting plate and the second pipe positioned closer to the supporting member 3; the diameter of the first pipe is larger than the diameter of the second pipe, so that when the first pipe is fully retracted into itself, both ends of the first pipe can abut against the supporting member 3, thereby playing a limiting role. In other words, the length of the first pipe can be used to control the clamping degree of the heat insulation cover 21 on the tank 1, providing greater controllability. Of course, the limiting telescopic rod 4 is not limited to a two-stage telescopic rod, but can also be three-stage or four-stage, depending on actual needs.
[0044] As can be seen from the structure described above, the limiting telescopic rod 4 can play a limiting role, preventing the heat insulation cover 21 from clamping the tank 1 too tightly, and can also improve the stability of the connecting component 26 and the heat insulation cover 21 during the movement process.
[0045] Furthermore, it should be noted that the structure is not limited to the above-mentioned structure using the limiting telescopic rod 4. The following structure can also be used for limiting and increasing the stability of the connecting member 26 during movement. Further, preferably, the modularly assembled solid hydrogen storage system also includes a limiting rod, and this limiting rod is non-retractable. The limiting rod includes a first limiting rod part and a second limiting rod part connected in sequence, and the diameter of the first limiting rod part is larger than the diameter of the second limiting rod part. The first limiting rod part is fixedly connected to the connecting member 26. The supporting member 3 forms a mating through hole, and the second limiting rod part is movably inserted into the mating through hole. The diameter of the mating through hole is larger than the diameter of the second limiting rod part, and the diameter of the mating through hole is smaller than the diameter of the first limiting rod part.
[0046] As can be seen from the structure described above, as the first driving member 25 retracts, it drives the connecting member 26 to move toward the supporting member 3. At the same time, the connecting member 26 pushes the first limiting rod and the second limiting rod to move, so that the second limiting rod is completely retracted into the supporting member 3 and abuts against the outer periphery of the mating through hole, thereby playing a limiting role and also increasing the stability of the connecting member 26 during movement.
[0047] In this embodiment, preferably, as follows: Figure 1 As shown, at least a portion of the first delivery pipe 23 near the pump body is a flexible hose, which ensures that the first delivery pipe can move synchronously with the heat insulation cover 21, avoiding problems such as jamming or inability to move.
[0048] It should be noted that, except for the part of the first delivery pipe 23 near the pump body which is designed as a flexible tube, the rest can be set as a rigid tube. Furthermore, this modular solid hydrogen storage system also includes a support telescopic tube. One end of the support telescopic tube is fixed to the support member 3, and the other end of the support telescopic tube is fixedly connected to the rigid tube structure, thus serving to support the rigid tube structure.
[0049] Furthermore, it should be noted that the design is not limited to a portion of the first conveying pipe 23 being made into a flexible hose; the entire first conveying pipe 23 can also be designed as a flexible hose, depending on the specific needs. Of course, it is not limited to the above; the first conveying pipe 23 can also be a rigid pipe, with a sliding fit between it and the pump body. Preferably, the outlet end of the pump body can be lengthened, and one end of the first conveying pipe 23 slides into the lengthened outlet end through a dynamic seal.
[0050] In this embodiment, preferably, as follows: Figure 1 As shown, at least a portion of the second delivery pipe 24 near the pump body is a flexible hose, which ensures that the second delivery pipe can move synchronously with the heat insulation cover 21, avoiding problems such as jamming or inability to move.
[0051] It should be noted that, except for the part of the second delivery pipe 24 near the pump body which is designed as a flexible tube, the rest can be set as a rigid tube. Furthermore, the modular solid hydrogen storage system also includes a support telescopic tube. One end of the support telescopic tube is fixed to the support member 3, and the other end of the support telescopic tube is fixedly connected to the rigid tube structure, thus serving to support the rigid tube structure.
[0052] Furthermore, it should be noted that the design of the second conveying pipe 24 as a flexible hose is not limited to the above-mentioned partial design; the entire second conveying pipe 24 can also be designed as a flexible hose, depending on the actual needs. Of course, it is not limited to the above; the second conveying pipe 24 can also be a rigid pipe, and it can slide in conjunction with the pump body. Preferably, the outlet end of the pump body can be lengthened, and one end of the second conveying pipe 24 slides in conjunction with the lengthened outlet end through a dynamic seal.
[0053] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, the modularly assembled solid hydrogen storage system also includes a bottom support member 5, a bracket 6, and two clamping assemblies 7; wherein, the bracket 6 is disposed on the bottom support member 5 and located on the side of the support member 3, and the two clamping assemblies 7 are disposed on the other opposite sides of the support member 3.
[0054] Each clamping component 7 includes a second driving member 71 and a clamping member 72. The second driving member 71 is disposed on the bracket 6, and the driving end of the second driving member 71 is connected to the clamping member 72. The second driving member 71 can drive the clamping member 72 to be disposed toward or away from the support member 3, so as to clamp or release the support member 3.
[0055] As can be seen from the structure described above, the second driving members 71 on the left and right sides of the support member 3 can drive the clamping members 72 to be positioned toward or away from the support member 3 in order to clamp or release the support member 3. In particular, the clamping members 72 can be used to clamp the support member 3, thereby increasing the stability and reliability of the structure.
[0056] Furthermore, preferably, the support member 3 can sit on the bottom support member 5, and the two are not connected. The bottom support member 5 serves to support the support member 3. Of course, it is not limited to this. The support member 3 may not sit on the bottom support member 5, but may be located on the side of the bottom support member 5, depending on the actual needs.
[0057] Furthermore, preferably, the support 6 includes a partition plate 61 and two side panels 62, all three of which are placed parallel to the vertical direction. The two side panels 62 are respectively arranged on opposite sides of the partition plate 61 to form a C-shaped structure, and this C-shaped structure separates the combined structure of the tank 1 and the thermal management module from the support structure. Of course, the structure of the support 6 is not limited to this.
[0058] In this embodiment, preferably, as follows: Figure 3 As shown, the modularly assembled solid hydrogen storage system also includes a base 8, which is fixed to the upper surface of the bottom support member 5, and the tank 1 is mounted on the base 8.
[0059] As can be seen from the structure described above, the base 8 serves to support the tank 1 and prevent the heat insulation covers 21 on the left and right sides from interfering with the ground during movement.
[0060] Furthermore, preferably, the tank body 1 and the base 8 are detachably connected by fastening members such as screws or bolts, and preferably, a flange can be provided on the outer periphery of the tank body 1, and the flange is detachably connected to the base 8 by fastening members such as screws or bolts.

[0063] As described above, the connecting frame 9 can be used to support the valve pipe assembly 10, which controls the hydrogen filling and releasing operations of the materials inside the tank 1. The valve pipe assembly 10 is an existing structure and will not be described in detail here. Alternatively, the connecting frame 9 and valve pipe assembly 10 can be omitted, depending on actual needs.
