Description
Technical Field
[0001] This utility model relates to the field of hydrogen storage equipment technology, and in particular to a hydrogen storage device based on magnesium-based solid hydrogen storage material. Background Technology
[0002] With the booming development of the hydrogen energy industry, hydrogen storage devices based on magnesium-based solid-state hydrogen storage materials have gradually become a research and application hotspot. Magnesium-based solid-state hydrogen storage materials have significant advantages such as high hydrogen storage capacity, abundant resources, relatively low cost, and environmental friendliness. These hydrogen storage devices demonstrate enormous potential in the field of hydrogen energy storage and transportation, providing a stable and reliable hydrogen supply for hydrogen fuel cell vehicles, distributed power generation systems, and other applications. This effectively promotes the large-scale application of hydrogen energy in multiple fields, contributes to the transformation and upgrading of the energy structure, reduces dependence on traditional fossil fuels, and is of paramount importance to achieving carbon peaking and carbon neutrality goals.
[0003] Existing hydrogen storage devices based on magnesium-based solid hydrogen storage materials generally include a storage tank to contain the magnesium-based solid hydrogen storage material and store hydrogen gas. The storage tank is connected to inlet and outlet hydrogen pipelines, and the flow of hydrogen is controlled by specialized valves. The typical workflow involves filling the storage tank with hydrogen gas through the inlet pipeline at locations such as hydrogen refueling stations. The hydrogen gas then reacts with the magnesium-based solid hydrogen storage material under specific pressure and temperature conditions for storage. When hydrogen is needed, the temperature and pressure conditions in the storage tank are adjusted to desorb hydrogen from the magnesium-based solid hydrogen storage material, and the hydrogen is then transported to the hydrogen-using equipment via the outlet pipeline.
[0004] However, existing hydrogen storage devices have certain shortcomings in terms of sealing. Due to the extremely small size and strong permeability of hydrogen molecules, traditional sealing structures cannot maintain good sealing performance over long-term use. As time goes by and the equipment is frequently operated, gaps easily form between the sealing structure and the equipment, leading to increasingly serious hydrogen leakage. This not only results in a large waste of hydrogen and increases operating costs, but also poses serious safety hazards, such as explosions in certain environments. This severely limits the further promotion and application of hydrogen storage devices based on magnesium-based solid hydrogen storage materials. Therefore, a hydrogen storage device based on magnesium-based solid hydrogen storage materials is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a hydrogen storage device based on magnesium-based solid hydrogen storage material, which aims to improve the problem that after long-term use, gaps may easily form between the sealing structure and the equipment, leading to hydrogen leakage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A hydrogen storage device based on magnesium-based solid hydrogen storage material includes a storage tank, a heat dissipation component is provided on the outer wall of the storage tank, and fixed pipes are fixedly connected to both sides inside the storage tank, with a sealing component provided inside each fixed pipe.
[0008] The sealing assembly includes multiple sealing rings II. Each fixed tube has a support base fixedly connected to its outer wall. Each support base has a motor fixedly connected inside. Each motor output end has a connecting shaft fixedly connected to its output end. One end of each connecting shaft has a rotating ball fixedly connected to its output end. Each rotating ball has sealing rings II on both sides. Each sealing ring II has a fixing ring II fixedly connected to its outer wall. The fixing ring II is slidably connected inside the fixed tube. Each fixed tube has multiple fixing blocks fixedly connected inside. Each fixing block has a sleeve fixedly connected inside. Each sleeve has sliding connecting posts on both sides inside. One end of each connecting post is fixedly connected to the outer wall of the fixing ring II. Each sleeve has a spring inside. Both ends of each spring are fixedly connected between the connecting posts on adjacent sides.

[0010] Each of the fixed tubes is fixedly connected to a hinge on its outer wall, and each of the hinges is fixedly connected to a cover plate on one side.
[0011] As a further description of the above technical solution:
[0012] The bottom of each of the cover plates is located inside the fixed tube, and a fixing ring is fixedly connected to the inner wall of each fixed tube;
[0013] As a further description of the above technical solution:
[0014] Each of the fixed rings is fixedly connected to a sealing ring, the top of each sealing ring is in contact with the bottom of the cover plate, and a base is fixedly connected to both sides of the bottom of the storage tank.
[0015] As a further description of the above technical solution:
[0016] The heat dissipation assembly includes multiple Venturi tubes located outside the storage tank, and multiple fixing rings are fixedly connected to the outer wall of the storage tank.
[0017] As a further description of the above technical solution:
[0018] Each of the three fixed rings is fixedly connected to the outer wall of the Venturi tube, which has a structure with large ends and a small middle, and is used to drive airflow.
[0019] As a further description of the above technical solution:
[0020] Each of the three fixed rings has multiple guide plates fixedly connected to one side. The bottom of the guide plate is fixedly connected to the outer wall of the storage tank. The guide plate is used to guide the airflow.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the spring's rebound force pushes the two sealing rings on both sides to compress the outer wall of the rotating ball, while the cover plate compresses the first sealing ring, thereby achieving a multi-seal effect on the equipment. This solves the problem that after long-term use, gaps may easily exist between the sealing structure and the equipment, leading to hydrogen leakage, and enhances the sealing effect of the equipment.
[0023] 2. In this utility model, the air pressure is reduced by the narrow area in the middle of the venturi tube, which makes the air flow faster. The air is guided to the outer wall of the storage tank by the guide plate, which increases the contact surface between the air and the equipment and realizes heat dissipation of the equipment. This solves the problem that the heat emitted by the equipment is usually dissipated by natural wind, which is easy to cause difficulty in timely heat dissipation. This enhances the heat dissipation effect of the equipment. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-4 The present invention provides an embodiment of a hydrogen storage device based on magnesium-based solid hydrogen storage material, comprising a storage tank 1, a heat dissipation component provided on the outer wall of the storage tank 1, and fixed pipes 3 fixedly connected to both sides inside the storage tank 1, with a sealing component provided inside each fixed pipe 3.
[0033] The sealing assembly includes multiple sealing rings 11, each of which prevents liquid or gas leakage and ensures the system's airtightness. Each fixed pipe 3 has a support 7 fixedly connected to its outer wall. Each support 7 has a motor 8 fixedly connected inside its interior. Each motor 8 has a connecting shaft 9 fixedly connected to its output end. Each connecting shaft 9 has a rotating ball 10 fixedly connected to one end. Each rotating ball 10 has two sealing rings 11 on both sides, ensuring no leakage occurs during rotation. Each sealing ring 11 has a fixing ring 12 fixedly connected to its outer wall, securing the sealing ring 11 in the correct position for a tight seal. The fixing ring 12 is slidably connected inside the fixed pipe 3. Each fixed pipe 3 has multiple fixing blocks 13 fixedly connected inside its interior. Each fixing block 13 has a sleeve 14 fixedly connected inside its interior. Each sleeve 14 has two slidably connected posts 15 on both sides inside its interior. One end of each post 15 is fixedly connected to the outer wall of the fixing ring 12, supporting its movement. Each sleeve 14 is equipped with a spring 16 inside, and both ends of each spring 16 are fixedly connected between adjacent connecting posts 15. Each fixed tube 3 is fixedly connected to a hinge 20 on its outer wall, allowing the cover plate 4 to be easily opened or closed for maintenance. Each hinge 20 is fixedly connected to a cover plate 4 on one side, sealing the interior of the equipment. The bottom of each cover plate 4 is located inside the fixed tube 3, increasing sealing and preventing leakage. Each fixed tube 3 has a fixed ring 5 fixedly connected to its inner wall, and each fixed ring 5 has a sealing ring 6 fixedly connected inside it. The sealing ring 6 seals the opening of the fixed tube 3 to prevent leakage, and the top of each sealing ring 6 fits against the bottom of the cover plate 4, enhancing the sealing effect. Bases 2 are fixedly connected to both sides of the bottom of the storage tank 1.
[0034] Specifically, in the sealing operation process of the equipment, motor 8 is started first. Motor 8, as a power source, has its output end connected to connecting shaft 9, converting electrical energy into mechanical energy to drive the connecting shaft 9. One end of the connecting shaft 9 is fitted with a rotating ball 10. Under the action of motor 8, the rotating ball 10 can rotate precisely 90 degrees. Initially, the rotating ball 10 is in the groove of sealing ring 2 11. After rotating 90 degrees, the rotating ball 10 separates from the groove of sealing ring 2 11, achieving closure of the storage tank 1. Simultaneously, spring 16 is connected to connecting posts 15 at both ends. Under the elastic potential energy of spring 16, it pushes the connecting posts 15 on both sides to move to the opposite side. The movement of the connecting posts 15 causes the sealing ring 2 11 connected to them to displace, allowing the sealing ring 2 11 on both sides to press against the outer wall of the rotating ball 10, ensuring a tight fit between the sealing ring 2 11 and the outer wall of the rotating ball 10. This tight fit enhances the sealing effect between the rotating ball 10 and the inside of the fixed tube 3, effectively preventing leakage of substances in the storage tank 1. After completing the above steps, the cover plate 4 is rotated. When the cover plate 4 is rotated, the outer wall of the cover plate 4 gradually moves into the inside of the fixed tube 3. During this process, the cover plate 4 will squeeze the sealing ring 6. Due to the compression of the cover plate 4, the sealing ring 6 will deform and fill the tiny gap between the fixed tube 3 and the cover plate 4, thereby sealing the connection between the fixed tube 3 and the cover plate 4. Through the sealing of the rotating ball 10 and the sealing ring 11 and the sealing of the cover plate 4 and the sealing ring 6, a multiple sealing mechanism is achieved, which enhances the overall sealing effect of the equipment, ensures the safe and stable operation of the equipment and the storage quality of the substances in the storage tank 1.
[0035] Reference Figure 1 and Figure 5 The heat dissipation assembly includes multiple Venturi tubes 18, which are located outside the storage tank 1 to ensure that the airflow path is not interfered with by the internal structure, thereby improving heat dissipation performance. Multiple fixing rings 17 are fixedly connected to the outer wall of the storage tank 1 to fix the position of the Venturi tubes 18, ensuring their stability and effective heat dissipation. Each fixing ring 17 is fixedly connected to the outer wall of the Venturi tube 18. The Venturi tube 18 has a structure with large ends and a small middle. This structure helps to accelerate the airflow in the pipe and increase the airflow velocity, thereby enhancing the heat dissipation effect and promoting airflow. Multiple guide plates 19 are fixedly connected to one side of each fixing ring 17. The guide plates 19 adjust the airflow direction so that the airflow flows more orderly to the area that needs to be cooled. The bottom of the guide plates 19 is fixedly connected to the outer wall of the storage tank 1 to ensure that the guide plates 19 are stable and reliable and to avoid external forces affecting their function.
[0036] Specifically, during the heat dissipation process of the equipment, outside air first enters the internal space of the Venturi tube 18. The Venturi tube 18 has a special structural design with a narrow section in the middle. According to Bernoulli's principle, when air flows through this narrow section, the cross-sectional area of the airflow decreases, resulting in an increase in air velocity and a corresponding decrease in air pressure. This decrease in pressure and increase in velocity create a pressure difference, further promoting the continuous high-speed flow of air. Subsequently, through the outlet at one end of the Venturi tube 18, the accelerated air is guided to the outer wall of the storage tank 1. At the same time, the guide plate 19 is designed with its shape and angle according to aerodynamic principles, which can effectively guide and optimize the airflow direction from the Venturi tube 18. Through the function of the guide plate 19, more air can come into even and sufficient contact with the outer wall of the storage tank 1. During the contact between the air and the outer wall of the storage tank 1, heat exchange occurs. The air carries away the heat from the outer wall of the storage tank 1, thereby effectively reducing the temperature of the outer wall of the storage tank 1. This achieves the purpose of blowing away the hot air from the outer wall of the storage tank 1, significantly enhancing the overall heat dissipation effect of the equipment and ensuring stable operation of the equipment in a suitable temperature environment.
[0037] Working principle: During the sealing process, motor 8 is started, and the output end of motor 8 drives the rotating ball 10 at one end of the connecting shaft 9 to rotate 90 degrees, causing the rotating ball 10 to separate from the groove of the sealing ring 11, thus closing the inside of the storage tank 1. The rebound force of spring 16 pushes the connecting columns 15 on both sides to move to opposite sides, causing the sealing rings 11 on both sides to press against the outer wall of the rotating ball 10, ensuring a tight fit between the sealing rings 11 and the outer wall of the rotating ball 10, enhancing the sealing effect between the rotating ball 10 and the inside of the fixed tube 3. Then, the cover plate 4 is rotated, causing the outer wall of the cover plate 4 to move into the inside of the fixed tube 3, and pressing against the sealing ring 11. 6. Extrusion is performed, and the connection between the fixed tube 3 and the cover plate 4 is sealed using the sealing ring 6, achieving multiple seals and enhancing the sealing effect of the equipment. During the heat dissipation process, air enters the interior of the venturi tube 18. The narrow area in the middle of the venturi tube 18 reduces the nearby air pressure and strengthens the airflow. Then, one end of the venturi tube 18 guides the air to the outer wall of the storage tank 1. At the same time, the guide plate 19 guides the airflow direction to ensure that more air can contact the outer wall of the storage tank 1, thereby blowing away the hot air on the outer wall of the storage tank 1 and enhancing the heat dissipation effect of the equipment.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
