Description

Technical Field

[0001] This utility model relates to the field of solid hydrogen storage tank technology, and in particular to a solid hydrogen storage tank tank changing cabinet. Background Technology

[0002] Hydrogen energy is an ideal clean energy source, with no pollution or carbon emissions during its use. Furthermore, its diverse production methods enhance the flexibility and stability of the energy system. Hydrogen energy is an indispensable part of the future energy system transformation. The hydrogen energy industry has begun to form four major segments: production, storage, transportation, and application, with increasingly diversified utilization methods. Upstream production mainly involves methods such as hydrogen production from fossil fuels, industrial by-product hydrogen, and water electrolysis. Midstream storage and transportation utilize gaseous, liquid, and solid forms, with the construction of infrastructure such as hydrogen refueling stations being a crucial component. Downstream applications currently focus on the industrial sector, but are expected to expand into transportation, industry, construction, energy storage, and other fields in the future.

[0003] Solid-state hydrogen storage has broad application prospects in many fields due to its advantages such as high volumetric hydrogen storage density, good safety, and long storage time. Solid-state hydrogen storage materials are mainly divided into two categories: physical adsorption hydrogen storage materials and chemical adsorption hydrogen storage materials. Physical adsorption hydrogen storage materials: These materials mainly utilize the large specific surface area of ​​porous materials to adsorb hydrogen molecules onto the surface through van der Waals forces. Common physical adsorption hydrogen storage materials include carbon-based materials (such as activated carbon, graphite nanofibers, carbon nanofibers, carbon nanotubes, etc., especially graphene), inorganic porous materials (such as zeolites), and metal-organic frameworks (MOFs) and covalent organic frameworks (COFs). Chemical adsorption hydrogen storage materials: These materials store hydrogen gas by forming ionic or covalent bonds between hydrogen atoms and other elements, generating materials such as metal hydrides. Common chemical adsorption hydrogen storage materials include metal hydrides (such as LaNiH, MgH, etc.), as well as magnesium-based, rare-earth-based, titanium-based, cobalt-based, and vanadium-based metal hydrogen storage materials. After years of research and development, solid-state hydrogen storage has reached a stage where it can be used in civilian applications. Hydrogen can be stored and transported in the form of miniaturized solid-state hydrogen storage tanks. Compared with high-pressure gaseous hydrogen storage, solid-state hydrogen storage tanks have advantages in safety and reliability, and lower equipment requirements. Currently, mainstream solid-state hydrogen storage tanks mainly consist of solid hydrogen storage materials, stainless steel / aluminum shells, gas pipe channels, filters, heat dissipation fins, valves, and heating / cooling pipes. Because the pressure of solid-state hydrogen storage tanks is generally below 5 MPa, high-pressure valves are not required, improving safety. Solid-state hydrogen storage tanks are currently only used in portable hydrogen instruments (hydrogen atomic clocks), miniaturized portable fuel cells, fuel cell two-wheelers, three-wheelers, and forklifts, among other small equipment. For example, under the strategic background of "Bringing Hydrogen Energy Products to Every Household," Yong'anxing has adhered to independent technological innovation and achieved leapfrog development in recent years, developing and manufacturing hydrogen-powered bicycles, hydrogen fuel cells, hydrogen storage energy rods, and other hydrogen lifestyle products. Their independently developed hydrogen energy sticks utilize solid-state hydrogen storage technology, achieving a hydrogen storage capacity of 200L with a volume of only 0.39L. These energy sticks are used in their hydrogen-powered bicycles and are currently in operation in several cities. The deployed hydrogen-powered bicycles have a hydrogen storage capacity of 50 grams, a range of 50-60 kilometers, and a top speed of 24 kilometers per hour.

[0004] For these types of hydrogen-powered bicycles, the hydrogen fuel cells need to be replaced at designated replacement points. This still presents problems such as long distances for replacement, cumbersome operations, and time lost for equipment use, failing to adequately meet users' needs for large-scale and frequent replacements. To avoid these issues, there is an urgent need for a hydrogen fuel cell replacement cabinet that can store a large number of fuel cells, is easy to replace, is miniaturized, and can be deployed over a wide area.

[0043] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0044] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0045] This utility model provides a solid hydrogen storage tank replacement cabinet, in which solid hydrogen storage tanks 3, which utilize solid hydrogen storage technology to store hydrogen, are stored at a fixed location. This allows citizens to conveniently replenish hydrogen in bicycles and other two-wheeled vehicles by replacing the solid hydrogen storage tanks 3. Figure 1 As shown, the solid hydrogen storage tank changing cabinet includes a cabinet body 1, a controller, an exhaust system, and multiple storage cabinets 4 for placing the solid hydrogen storage tank 3. Figure 1 The number of storage cabinets 4 is for reference only; more cabinets 4 can be set according to actual needs. Multiple storage cabinets 4 are arrayed within the cabinet body 1. Each cabinet 4 has a hinged door 41 to prevent hydrogen gas from accidentally leaking from the solid hydrogen storage tank 3 and directly leaking outside the cabinet, thus improving the safety performance of the cabinet 4. An installation device 5 is installed inside the cabinet 4. The solid hydrogen storage tank 3 is detachably connected to the installation device 5. The independently set storage body effectively improves the safety of the solid hydrogen storage tank 3 during storage, and the installation device 5 improves the stability of the solid hydrogen storage tank 3 installation, preventing the solid hydrogen storage tank 3 from falling when the cabinet door 41 is opened, thus improving the safety performance of the solid hydrogen storage tank replacement cabinet. The exhaust system includes a first exhaust device 21 and multiple second exhaust devices 22 electrically connected to the controller. The controller uses an existing circuit structure / integrated chip; this application does not modify any circuit structure / chip of the controller. The controller controls the start / stop and power of the first exhaust device 21 and the multiple second exhaust devices 22. The inlet of the second extraction device 22 is connected to the storage cabinet 4, and the outlet of the second extraction device 22 is connected to the inlet of the first extraction device 21. The outlet of the first extraction device 21 is connected to a hydrogen collection device or a hydrogen processing device. The first extraction device 21 and the second extraction device 22 work together to extract air from each storage cabinet 4, preventing danger caused by excessive hydrogen concentration in the storage cabinet 4, further improving the safety performance of the solid hydrogen storage tank replacement cabinet. At the same time, it can also be used for daily ventilation in the storage cabinet 4 to keep the inside of the storage cabinet 4 dry.

[0046] like Figure 2As shown, the mounting device 5 includes a base 50, a first support arm 51, a second support arm 52, and at least one limiting arm 53. The base 50 is fixed to the bottom plate of the storage cabinet 4. The lower ends of the first support arm 51 and the second support arm 52 are both connected to the base 50. The first support arm 51 and the second support arm 52 are arranged opposite to each other, and the distance between the first support arm 51 and the second support arm 52 is greater than the outer diameter of the solid hydrogen storage tank 3. The solid hydrogen storage tank 3 is placed between the first support arm 51 and the second support arm 52 to limit the left and right swaying distance of the solid hydrogen storage tank 3. The side of the first support arm 51 and the second support arm 52 near the back panel of the storage cabinet 4 is connected by an arc-shaped plate. The shape of the arc-shaped plate matches the shape of the solid hydrogen storage tank 3 to limit the solid hydrogen storage tank 3 from tilting backward and prevent the solid hydrogen storage tank 3 from falling backward and hitting the back panel of the storage cabinet 4. The first end of the limiting arm 53 is hinged to the side of the first support arm 51 away from the back panel of the storage cabinet 4. In the storage state, the second end of the limiting arm 53 is connected to the side of the second support arm 52 away from the back panel of the storage cabinet 4 via a locking mechanism 54, which restricts the solid hydrogen storage tank 3 from tilting forward and locks the solid hydrogen storage tank 3 between the first support arm 51 and the second support arm 52, preventing the solid hydrogen storage tank 3 from falling and causing a safety accident when the cabinet door 41 is opened. Preferably, there are two limiting arms 53, which limit the upper and lower ends of the solid hydrogen storage tank 3 respectively. The gap between the limiting arms 53 or between the limiting arms 53 and the base 50 is smaller than the outer diameter of the solid hydrogen storage tank 3, preventing the solid hydrogen storage tank 3 from sliding out of the gap. When it is necessary to take out or put in the solid hydrogen storage tank 3, the locking mechanism 54 is unlocked and the limiting arm 53 is opened. The solid hydrogen storage tank 3 can be taken out or put in through the opening side of the mounting device 5, which is convenient.

[0047] In one implementation, see Figure 3 The locking mechanism 54 includes a lock body 541, a first hook 542, a second hook 543, a slider 544, and a lever 545. The lock body 541 is mounted on the second support arm 52 and has a lock hole. The slider 544 is slidably disposed within the lock body 541, and a spring is provided at the bottom of the slider 544 to provide upward support. The second hook 543 is disposed within the lock body 541 and connected to the slider 544. The lever 545 is connected to the slider 544 and partially located outside the lock body 541. The first hook 542 is mounted on the second end of the limiting arm 53. When locking the locking mechanism 54, the first hook 542 passes through the lock hole and connects to the second hook 543. When unlocking the locking mechanism 54, pressing down on the lever 545 drives the slider 544 downward, causing the second hook 543 to move downward, separating the first hook 542 from the second hook 543, and the slider 544 returns to its original position under the action of the spring.

[0048] In a preferred embodiment, the middle portions of the first support arm 51 and the second support arm 52 are both arc-shaped curved plates, creating a certain space between the two support arms and the solid hydrogen storage tank 3. Users can easily access and remove the solid hydrogen storage tank 3 by passing tools or their hands through this space, improving operational convenience. The base 50 is equipped with a flexible pad 55, such as a rubber pad. The top surface of the flexible pad 55 has blind holes that match the shape of the bottom of the solid hydrogen storage tank 3, preventing the bottom of the solid hydrogen storage tank 3 from bumping against the base 50. The blind holes also limit the lower end of the solid hydrogen storage tank 3, improving its stability.

[0049] like Figure 1 , Figure 4 and Figure 5 As shown, taking advantage of the light weight of hydrogen, a first through-hole is provided on the top panel of cabinet 1, and a first exhaust device 21 is installed in the first through-hole. A second through-hole is provided on the back panel of storage cabinet 4, and a second exhaust device 22 is installed in the second through-hole. The first exhaust device 21 and the second exhaust device 22 are preferably exhaust fans, which use wind power to expel the volatile hydrogen from cabinet 1. A receiving space 6 is provided between the back panel of cabinet 1 and the back panel of storage cabinet 4, and both the first through-hole and the second through-hole are connected to the receiving space 6. During exhaust, the second exhaust device 22 extracts the mixture of air and hydrogen from each storage cabinet 4 and delivers it to the receiving space 6. Hydrogen is light and easily rises to the top of the receiving space 6. Then, the first exhaust device 21 located at the top extracts the mixture from the receiving space 6 and delivers it to the outside of cabinet 1, where it is collected and further processed by a hydrogen collection device or a hydrogen treatment device to prevent the hydrogen concentration inside cabinet 1 and storage cabinet 4 from becoming too high and causing danger.

[0050] See Figure 1 At least one third through hole 43 is provided on the cabinet door 41 near its lower edge for air intake. When the second exhaust device 22 is off, the third through hole 43 at the lower edge reduces the efficiency of the rising hydrogen gas diffusing out of the cabinet 4. A dustproof screen is provided on the third through hole 43 to reduce the entry of foreign objects into the cabinet 4. The cabinet door 41 is connected to the cabinet 4 by a magnetic lock, which is electrically connected to the controller. The user opens the cabinet door 41 by operating the controller.

[0051] See Figure 1The solid hydrogen storage tank changing cabinet also includes a control device 7 and a power supply device 8, both of which are electrically connected to the controller. An isolation cabinet 10 is installed on the cabinet body 1, and both the control device 7 and the power supply device 8 are located within the isolation cabinet 10. The power supply device 8 provides power to other components inside the solid hydrogen storage tank changing cabinet, and can be a lithium battery or a storage battery. The control device 7 is a conventional device used by users to unlock the cabinet door 41 through conventional operations such as pressing buttons or swiping cards. The solid hydrogen storage tank changing cabinet also includes a human-machine interface screen 9, which is located inside the isolation cabinet 10 and electrically connected to the controller, used for displaying information and touch screen operation.

[0052] A hydrogen sensor 42 is installed on the top of the locker 4. The hydrogen sensor 42 can detect the hydrogen concentration inside the locker 4. The hydrogen sensor 42 is electrically connected to the controller and sends the detection data to the controller. It can also be connected to an external computer to send hydrogen concentration data to the administrator.

[0053] Furthermore, this utility model's solid hydrogen storage tank replacement cabinet can be independently installed in convenient outdoor areas, providing hydrogen energy users with a convenient and quick tank replacement platform. It allows direct replacement of the solid hydrogen storage tank 3 within cabinet 1, eliminating the need for hydrogen refueling and significantly reducing refueling time. The equipment is simple in principle, highly practical, and suitable for widespread use in the context of the initial energy transition, promoting the development and construction of civilian hydrogen energy.
