[0002] In the context of the transformation of the global energy structure, hydrogen energy, as a clean, efficient and renewable energy source, is regarded as an important component of future energy carriers. First of all, the only product of hydrogen combustion is water, which has almost no pollution to the environment. Secondly, hydrogen energy has an extremely high energy density, and the energy released by a unit mass of hydrogen energy far exceeds that of traditional fossil fuels. In addition, there are many ways to produce hydrogen, including electrolysis of water to produce hydrogen, and extracting hydrogen from industrial by-products. The sources are wide and renewable. At present, there are three main methods of storing hydrogen: gaseous, liquid, and solid. Solid-state hydrogen storage has obvious advantages over other hydrogen storage methods.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. In the description of the present invention, it should be noted that the term "or" is usually used in the sense of including "and / or", unless the content clearly indicates otherwise.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two elements.

In the description of the present invention, the meaning of "multiple" is at least two, such as two, three or more, etc., unless otherwise clearly and specifically limited.

[0031] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] First, to facilitate understanding of the embodiments of the present invention, some terms or nouns involved in the present invention are explained below:

[0033] Hydrogen storage alloy is a new type of alloy, which is unique in that it can absorb and release hydrogen under certain conditions. Hydrogen storage alloy is an alloy composed of multiple elements, and its typical composition is TiaVbCrcAldMe, where M represents at least one or two elements of Cu, Fe, Co, Ni, Si, Sn, Mo, and W. The proportion of these elements in the alloy has a certain range, such as 1.0≤a≤1.6, 0.2≤b≤1.0, etc.

[0034] Teaching demonstration refers to teachers presenting teaching content, teaching methods and teaching results through various forms of demonstrations, aiming to enhance students' understanding and memory of knowledge.

[0035] In order to solve the problems existing in the prior art, an embodiment of the present application provides a hydrogen storage teaching demonstration device.

[0036] like Figure 1 As shown, Figure 1 This is a schematic diagram of the three-dimensional structure of a hydrogen storage teaching and demonstration device of the present invention, which includes: a gas pipeline mechanism, which is used to connect to a gas distribution device to transport hydrogen, and the gas distribution device is used to input hydrogen into the gas pipeline mechanism; a hydrogen storage sample mechanism, which is connected to the gas pipeline mechanism and is used to store or release hydrogen and demonstrate the hydrogen storage or release process; and a supporting mechanism, which is connected to the gas pipeline mechanism and the hydrogen storage sample mechanism and is used to support the gas pipeline mechanism and the hydrogen storage sample mechanism.

[0037] Based on the above structure, the gas distribution device is a component for filling gas into the hydrogen storage teaching demonstration device. The gas distribution device is equivalent to a container for storing pure hydrogen. Based on the gas distribution device, hydrogen is filled into the hydrogen storage teaching device, so that the hydrogen storage teaching device can well demonstrate the process of hydrogen absorption and storage.

[0038] Optionally, when the hydrogen storage teaching device demonstrates the release of hydrogen, since the hydrogen pressure in the gas distribution device is relatively high and hydrogen can no longer be stored, it will be released to other locations through the gas pipeline mechanism, thereby realizing the process of hydrogen storage and release, which can be displayed and viewed more intuitively.

[0039] Optionally, the gas pipeline mechanism is used to transport hydrogen, that is, the hydrogen in the gas distribution device is transported to the hydrogen storage sample mechanism for storage through the gas pipeline mechanism, and the stored hydrogen can be released from the hydrogen storage sample mechanism, released into the gas pipeline mechanism, and then transported to other locations by the gas pipeline mechanism.

[0040] Optionally, the hydrogen storage sample mechanism is a transparent reaction container, and the reaction is carried out in the hydrogen storage sample mechanism. Due to the transparent container, the reaction state and process can be observed in real time, and observation and teaching can be carried out effectively and intuitively.

[0041] Optionally, the gas pipeline mechanism is a pipeline, and the gas pipeline mechanism needs to be supported, and the gas pipeline mechanism and the hydrogen storage sample mechanism need to be fixed to prevent the two from separating during the reaction, thereby effectively ensuring the progress of the reaction, the integrity and stability of the entire device.

[0042] In some preferred embodiments, the hydrogen storage sample mechanism includes: a sample chamber 2, which is connected to the gas pipeline mechanism, the sample chamber 2 includes a hydrogen storage alloy 207, the hydrogen storage alloy 207 is used to receive hydrogen transported by the gas pipeline mechanism, store the hydrogen within a first preset temperature range, and release the stored hydrogen within a second preset temperature range; a transparent chamber 301, which is arranged on the outside of the sample chamber 2 to wrap the sample chamber 2, the transparent chamber 301 includes a reserved port for injecting liquid, and the reserved port is used to inject the first liquid or the second liquid into the transparent chamber 301, wherein the temperature of the first liquid is within the first preset temperature range, and the temperature of the second liquid is within the second preset temperature range.

[0043] like Figure 2 as well as Figure 3 As shown, Figure 2 This is a schematic diagram of the three-dimensional structure of a sample tube in a hydrogen storage teaching demonstration device of the present invention. Figure 3 This is a schematic diagram of the cross-sectional structure of a sample tube in a hydrogen storage teaching demonstration device of the present invention. Based on the above structure, the activated hydrogen storage alloy 207 can absorb and release hydrogen when reaching a specific temperature and pressure; when the transparent chamber 301 is filled with a second liquid (the second liquid is a constant temperature liquid within a second preset temperature range), the sample chamber 2 is completely provided with suitable temperature conditions to start the hydrogen storage alloy 207 dehydrogenation process, and the released hydrogen enters the gas pipeline mechanism. The second liquid immerses the sample chamber 2 to provide energy for the hydrogen storage process.

[0044] When storing hydrogen, a first liquid may be placed in the transparent chamber 301 to immerse the sample chamber 2. At the same time, under the action of high-strength hydrogen pressure, the hydrogen storage alloy 207 absorbs hydrogen to achieve the effect of storing hydrogen.

[0045] In some preferred embodiments, the transparent chamber 301 is cylindrical and is used to amplify the hydrogen storage or release process in the sample chamber 2 .

[0046] Based on the above structure, the transparent chamber 301 is set to be cylindrical to form a convex surface, so as to magnify the sample chamber 2 in the transparent chamber 301, achieve the magnification effect, and more clearly observe the storage and release process of hydrogen by the hydrogen storage alloy 207, effectively realizing an intuitive and clear teaching display.

[0047] In some preferred embodiments, the sample chamber 2 includes: a joint body 201, connected to the gas pipeline mechanism, for receiving hydrogen transported by the gas pipeline mechanism; a transparent sample tube 203, connected to the joint body 201, and the transparent sample tube 203 contains a hydrogen storage alloy 207; a connector 202, arranged between the joint body 201 and the transparent sample tube 203, for fixing the joint body 201 on the transparent sample tube 203.

[0048] Based on the above structure, the connector body 201 is used to connect the gas pipeline mechanism and the transparent sample tube 203. Generally, the transparent sample tube 203 is in the shape of a test tube with a larger opening at the upper end. In order to ensure the connection with the gas pipeline mechanism and the fixed connection, a connector body 201 is provided to connect the gas pipeline mechanism with different diameters to the connector body 201.

[0049] Optionally, a connector 202 is provided to fix the connector body 201 and the transparent sample tube 203. The leveling head is in the shape of a ring. The transparent sample tube 203 passes through the middle part of the connector 202 and is clamped on the connector 202. The connector 202 is provided with an internal thread, and the connector body 201 is provided with an external thread. The connector body 201 is fixed on the transparent sample tube 203 through the cooperation of the internal thread and the external thread.

[0050] In some preferred embodiments, the sample chamber 2 further includes: a sealing ring 205, disposed between the transparent sample tube 203 and the connector body 201, for sealing the gap between the connector body 201 and the transparent sample tube 203; and a clamping ring 206, disposed on the periphery of the sealing ring 205, for reinforcing the sealing degree.

[0051] Based on the above structure, in order to avoid leakage of the transported hydrogen, the entire device needs to be sealed, especially the joint body 201 portion corresponding to more connection structures. A sealing ring 205 needs to be set between the joint body 201 and the transparent sample tube 203, so that the transparent sample tube 203 is tightly connected to the joint body 201. At the same time, under the action of the thread of the connector 202, the thread is tightened so that the joint body 201 is tightly attached to the sealing ring 205, and the transparent sample tube 203 is also tightly attached to the sealing ring 205, thereby effectively achieving a sealing effect and avoiding leakage of hydrogen.

[0052] Optionally, a compression ring 206 is arranged on the outside of the sealing ring 205, and at the same time on the outside of the wall of the transparent sample tube 203, and is located inside the ring of the connector 202, that is, between the connector 202 and the transparent sample tube 203, and is used to seal the gap between the transparent sample tube 203 and the connector 202. When the connector 202 and the joint body 201 are tightened by threads, the compression ring 206 made of rubber will completely and hermetically close the gap at the connector 202, effectively improving the sealing effect and preventing hydrogen leakage.

[0053] In some preferred embodiments, the sample chamber 2 further includes: a filter 204 disposed between the joint body 201 and the transparent sample tube 203 , for preventing particles of the hydrogen storage alloy 207 from entering the joint body 201 .

[0054] Based on the above structure, the hydrogen storage alloy 207 is in powder or solid form. During the release of hydrogen, some powder may move upward with the hydrogen, and then enter the gas pipeline mechanism along the joint body 201, causing the gas pipeline mechanism to be blocked after long-term use. Therefore, a filter 204 is required. The filter 204 is arranged between the joint body 201 and the transparent sample tube 203 to prevent particles of the hydrogen storage alloy 207 from entering the joint body 201.

[0055] In some preferred embodiments, the sample chamber 2 also includes: a protective cover 208, which is arranged on the outside of the transparent sample tube 203 to prevent fragments from scattering after the transparent sample tube 203 bursts; a tightening screw 209, which is arranged between the protective cover 208 and the transparent sample tube 203 to fix the protective cover 208 on the outside of the transparent sample tube 203.

[0056] Based on the above structure, in the process of transporting hydrogen into the transparent sample tube 203, the hydrogen storage alloy 207 will continuously absorb and store hydrogen. However, there may be too much hydrogen content, resulting in a high pressure in the transparent sample tube 203, and the hydrogen storage alloy 207 cannot absorb the remaining hydrogen, resulting in the transparent sample tube 203 bursting. In this case, in order to avoid the transparent sample tube 203 from being broken due to the high pressure and causing excessive impact, thereby endangering the personal safety of the surrounding personnel, it is necessary to set a stronger protective cover 208 on the outside of the transparent sample tube 203. The protective cover 208 is also transparent, and the hardness of the protective cover 208 needs to be greater than that of the transparent sample tube 203, so as to effectively avoid the transparent sample tube 203 from scattering fragments after the explosion, thereby endangering the safety of the surrounding personnel.

[0057] Optionally, a clamping screw 209 is disposed between the protective cover 208 and the transparent sample tube 203 to fix the protective cover 208 to the outside of the transparent sample tube 203 , thereby effectively preventing the protective cover 208 from falling off and ensuring the protective effect of the protective cover 208 .

[0058] In some preferred embodiments, the gas pipeline mechanism includes: a hydrogen pipe 102, used to receive and transport hydrogen; a quick interface 101, one end of which is connected to the gas distribution device and the other end is connected to the hydrogen pipe 102, used to fix the gas distribution device to the hydrogen pipe 102; a first valve 103, installed on the hydrogen pipe 102, used to control the transportation of hydrogen.

[0059] like Figure 1 As shown, Figure 1 It is a three-dimensional structural schematic diagram of a hydrogen storage teaching demonstration device of the present invention. Based on the above structure, the gas distribution device is connected to the hydrogen pipe 102 through the quick interface 101 to provide high-pressure hydrogen so that the hydrogen storage alloy 207 absorbs hydrogen again.

[0060] Optionally, a first valve 103 is provided on the hydrogen pipe 102 to effectively control the transportation of hydrogen. After providing high-pressure hydrogen, the first valve 103 can be closed and the gas distribution device can be evacuated. Only the hydrogen storage teaching display device needs to be carried to the demonstration destination, thereby effectively realizing the portability of the hydrogen storage teaching display device.

[0061] In some preferred embodiments, the gas pipeline mechanism also includes: an expansion body 106, installed at one end of the hydrogen pipe 102 away from the quick interface 101, for receiving the hydrogen released from the hydrogen storage sample mechanism; a second valve 105, arranged on the hydrogen pipe 102 and installed between the first valve 103 and the expansion body 106, for controlling the transportation of the released hydrogen.

[0062] Based on the above structure, the sample chamber 2 is at least connected to the expansion body 106 for inflating the expansion body 106; the expansion body 106 and the sample chamber 2 are connected via the second valve 105 so that the gas between the expansion body 106 and the sample chamber 2 flows or does not flow; the gas distribution device is connected to the sample chamber 2 via a gas pipeline, and controls whether the gas flows via the first valve 103.

[0063] In the above manner, the first valve 103 controls the hydrogen to enter the sample chamber 2, so that the process of hydrogen storage can be displayed, and the second valve 105 controls the hydrogen to be released from the sample chamber 2, so that the process of hydrogen release can be displayed.

[0064] like Figure 4 As shown, Figure 4The diagram is a schematic diagram showing the diameter change of the expansion body 106 with time in the hydrogen storage teaching demonstration device of the present invention during the demonstration process. After the hydrogen is released, it will pass through the hydrogen pipe 102 and enter the expansion body 106. The expansion body 106 is made of rubber material with elasticity, and a balloon can be placed therein. The expansion body 106 needs to be fixedly connected to the hydrogen pipe 102. After the hydrogen is introduced into the expansion body 106, the volume gradually increases, that is, the diameter of the expansion body 106 gradually increases, and the diameter of the expansion body 106 increases proportionally with time.

[0065] In some preferred embodiments, the gas pipeline mechanism also includes: a three-way valve 104, installed between the first valve 103 and the second valve 105, including a first interface, a second interface and a third interface, the first interface is connected to the hydrogen pipe 102, and is installed at one end close to the first valve 103, the second interface is connected to the hydrogen pipe 102, and is installed at one end close to the second valve 105, and the third interface is connected to the hydrogen storage sample mechanism.

[0066] Based on the above structure, the tee 104 is a pipeline with three interfaces, which is arranged on the hydrogen pipe 102, one end of which is connected to the first valve 103, one end of which is connected to the second valve 105, and the other end of which is connected to the hydrogen storage sample mechanism, that is, connected to the joint body 201. Hydrogen is introduced into the first valve 103, and the hydrogen is transported to the joint body 201 through the tee 104. At this time, the first valve 103 is opened, the second valve 105 is closed, and the hydrogen enters the transparent sample tube 203 for reaction. When it is necessary to perform deflation display, the first valve 103 is closed, and the second valve 105 is opened. At this time, the gas enters the tee 104 from the joint body 201, and is transported to the second valve 105 until it is transported to the expansion body 106 for collection.

[0067] In some preferred embodiments, the support mechanism includes: a support frame 303, including a vertical plate and a horizontal plate, the vertical plate is parallel to the hydrogen storage sample mechanism, the horizontal plate is installed on the vertical plate, the horizontal plate is perpendicular to the vertical plate, the horizontal plate is at the same height as the gas pipeline mechanism, and the horizontal plate is used to fix the position of the gas pipeline mechanism; a bottom plate 301 is installed under the hydrogen storage sample mechanism and the support frame 303, and is used to fix and support the hydrogen storage sample mechanism and the support frame 303.

[0068] Based on the above structure, since the volume of the transparent chamber 301 is much larger than the transparent sample tube 203, the transparent sample tube 203 cannot be fixed in the middle of the transparent chamber 301. If there is no mechanism to fix the transparent sample tube 203, the transparent sample tube 203 may fall into the transparent chamber 301, so a support frame 303 is required to fix the transparent sample tube 203.

[0069] Specifically, since the transparent sample tube 203 is fixedly connected to the gas pipeline mechanism, after the gas pipeline mechanism is fixed, the transparent sample tube 203 will also be fixed. The transparent sample tube 203 is fixed by fixing the gas pipeline mechanism.

[0070] Optionally, after fixing the transparent sample tube 203 and the transparent chamber 301, since the two are two completely separate parts, there is a possibility that the device will be disassembled or shifted during transportation, so the base plate 301 is used to fix both the hydrogen storage sample mechanism and the support frame 303, so that the entire device forms a whole and is not easy to separate during transportation.

[0071] Through the above-mentioned hydrogen storage teaching demonstration device, hydrogen is transported into the hydrogen storage sample mechanism based on the gas pipeline, so that the hydrogen storage sample mechanism can complete the demonstration process of storing or releasing hydrogen, thereby providing a clearer and more intuitive teaching purpose to other personnel, thereby achieving the technical effect of improving the portability, safety and intuitiveness of teaching, and further solving the technical problem that it is difficult for students to understand the principles and processes of hydrogen storage due to the relatively abstract content of popular science teaching of hydrogen storage knowledge and the lack of intuitive demonstration and operation.

[0072] At the same time, the hydrogen storage teaching demonstration device does not need to rely on an external hydrogen source, simplifies the operation process, avoids cumbersome gas access steps, and greatly improves the convenience and safety of teaching. In addition, the device can be reused and has a significant demonstration effect. It can not only help students better understand the working principle of hydrogen storage alloy 207, but also is an ideal experimental teaching tool suitable for classroom demonstrations and laboratory teaching.

[0073] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
