[0023] 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.

[0024] Reference Figure 1 - Figure 4This utility model provides an embodiment of a magnesium-based solid hydrogen storage material performance testing mechanism, comprising a testing platform 1, which serves as the basic support platform for the entire testing mechanism, providing stable support for the subsequent installation of various components. A data processor 2 is fixedly connected to the testing platform 1, responsible for receiving, storing, analyzing, and processing various signals from a data monitor 14. A controller 3 is fixedly connected to the upper surface of the testing platform 1, serving as the control center of the entire device. Operators input various test parameters through its intuitive control panel. A reaction chamber 6 is fixedly connected to the upper surface of the testing platform 1, and a heating block 7 is fixedly connected inside the reaction chamber 6. The heating block 7 is made of a high thermal conductivity metal material, such as aluminum alloy or copper alloy, and its shape is adapted to the inner wall of the bottom of the reaction chamber 6 to ensure a tight fit for efficient heat transfer. An installation assembly is provided on one side of the inner wall of the reaction chamber 6, and a sealing assembly is provided on the inner wall of the reaction chamber 6. The installation assembly includes a connecting seat 8, which has precisely machined slides and spring mounting grooves inside, providing guidance and support for the slider 13 and the spring 12. One end of the connecting seat 8 is fixedly connected to the inner wall of the reaction chamber 6. A spring 12 is installed inside the connecting seat 8. During installation, the spring 12 is in a natural or slightly compressed state. When the slot seat 10 is installed, the pressure block 11 presses down on the slider 13, compressing the spring 12 and storing elastic potential energy. After the slot seat 10 is installed in place, the spring 12 releases its elastic potential energy. A pin 9 is fixedly connected to the outer wall of the connecting seat 8. After the slot seat 10 is installed in place, under the elastic force of the spring 12, the pin 9 accurately engages in the slot of the slot seat 10, forming a reliable mechanism. Mechanical locking prevents the slot seat 10 from shifting in the horizontal and vertical directions. The slot seat 10 is slidably connected to the outer wall of the connecting seat 8. The slot seat 10 is precisely matched with the pin 9 to ensure that the pin 9 can be smoothly inserted and lock the slot seat 10. A pressure block 11 is fixedly connected inside the slot seat 10. The function of the pressure block 11 is to transfer the installation force of the slot seat 10 to the spring 12. A slider 13 is slidably connected to the outer wall of the pressure block 11. The slider 13 is held in a certain position under the elastic force of the spring 12 to ensure that the pin 9 and the slot of the slot seat 10 are tightly engaged. The movement of slider 13 serves to transmit force and control the compression of spring 12, ensuring the normal operation of the mounting components. The outer wall of slider 13 is slidably connected to the inside of connecting seat 8, and the outer wall of pin 9 is slidably connected to the slot inside the slot seat 10. One end of slot seat 10 is fixedly connected to data monitor 14. The sealing component includes sealing ring 4, which always maintains a sealed state, effectively preventing hydrogen from leaking from reaction chamber 6. The outer wall of sealing ring 4 is slidably connected to the inner wall of reaction chamber 6, and the inner wall of sealing ring 4 is fixedly connected to the outer wall of cover plate 5. One end of spring 12 is fixedly connected to the lower surface of slider 13, and the other end of spring 12 is fixedly connected to the inside of connecting seat 8. Data processor 2 is electrically connected to controller 3, and controller 3 is electrically connected to heating block 7.

[0025] Reference Figure 1 and Figure 5A gas supply pipe 21 is fixedly connected inside the reaction chamber 6. The function of the gas supply pipe 21 is to stably deliver hydrogen supplied by the hydrogen source into the reaction chamber 6. Its diameter and length are reasonably selected according to the hydrogen flow requirements and equipment layout to ensure that the pressure loss is minimized and the flow is stable during the hydrogen delivery process. A valve body 17 is fixedly connected to one end of the gas supply pipe 21. The valve body 17 is designed to withstand a certain pressure and has good corrosion resistance to adapt to the working environment of the hydrogen supply system. A bracket 19 is fixedly connected to the inner wall of the valve body 17. A rotating shaft 18 is rotatably connected inside the valve body 17. The other end of the rotating shaft 18 is located inside the valve body 17. During rotation, the ball valve 20 can rotate synchronously with the rotating shaft 18. A handwheel 23 is fixedly connected to the outer wall of the rotating shaft 18. When the handwheel 23 is turned, a suitable torque can be applied to easily control the opening and closing of the ball valve 20. By turning the handwheel 23, the rotating shaft 18 is driven to rotate, thereby causing the ball valve 20 to rotate inside the valve body 17, realizing the control of the ball valve 20. For precise regulation of hydrogen flow, a ball valve 20 is fixedly connected to one end of the rotating shaft 18. When the ball valve 20 is fully closed, the ball and the valve seat fit tightly together, forming a reliable seal and preventing hydrogen flow. When the ball valve 20 is gradually opened, hydrogen enters the reaction chamber 6 through the gap between the ball and the valve seat. The hydrogen flow rate is proportional to the opening degree of the ball valve 20. A water pump 16 is fixedly connected to the upper surface of the detection platform 1. The main function of the water pump 16 is to provide power for the circulation of coolant, transporting coolant from the coolant source to the condenser tube 15, so that the coolant circulates in the condenser tube 15, carrying away the heat in the reaction chamber 6, thereby regulating the temperature of the reaction chamber 6. The output end of the water pump 16 is fixedly connected to the condenser tube 15, and the input end of the water pump 16 is fixedly connected to the water pump 16. An exhaust pipe 22 is fixedly connected inside the reaction chamber 6. The outer wall of the ball valve 20 is slidably connected to the inner wall of the valve body 17, and one side of the outer wall of the ball valve 20 is slidably connected to the inner wall of the bracket 19. The inner wall of the condenser tube 15 is fixedly connected to the outer wall of the reaction chamber 6.

[0026] Working principle: First, the magnesium-based solid hydrogen storage material sample to be tested is placed in a suitable position within the reaction chamber 6. Then, the slot seat 10 slides along the outer wall of the connecting seat 8, causing the pin 9 to slide along the internal slot of the slot seat 10, thus locking the pin 9 in the internal slot of the slot seat 10. During this process, the pressure block 11 presses down on 13, causing 13 to compress the spring 12, which slides along the inside of 8. After the slot seat 10 is installed in place, under the elastic force of the spring 12, the pin 9 tightly engages with the internal slot of the slot seat 10, thereby firmly installing the slot seat 10 and the data monitor 14 fixedly connected to one end thereon onto the connecting seat 8. This installation method utilizes the elasticity of the spring 12. Potential energy enables rapid installation, and when disassembly is required, simply reverse the operation to overcome the spring force of spring 12 and disengage the pin 9 from the internal slot of the slot seat 10, allowing the data monitor 14 to be easily removed for subsequent maintenance. Next, accurately place the cover plate 5 on top of the reaction chamber 6. The sealing ring 4 fixedly connected to the outer wall of the cover plate 5 slides tightly against the inner wall of the reaction chamber 6, forming a reliable seal to effectively prevent hydrogen leakage and ensure the airtightness of the test environment. Then, turn the handwheel 23, which drives the rotating shaft 18 to rotate, thereby causing the ball valve 20 fixedly connected to one end of the rotating shaft 18 to rotate on the inner wall of the valve body 17, thus opening the hydrogen supply channel. Hydrogen enters smoothly through the gas delivery pipe 21. Inside reaction chamber 6, controller 3 controls heating block 7 to start working according to a preset program, heating the magnesium-based solid hydrogen storage material inside reaction chamber 6 to simulate different temperature environments. Temperature has a crucial impact on the hydrogen absorption and desorption performance of magnesium-based solid hydrogen storage materials. When heating block 7 is working, the heat it generates is evenly transferred to the material and gas inside reaction chamber 6. Simultaneously, water pump 16 starts, delivering coolant to condenser pipe 15. Condenser pipe 15 cools and regulates reaction chamber 6 through heat exchange, maintaining the temperature inside reaction chamber 6 within a suitable test temperature range, thereby ensuring the accuracy and reliability of the test results. Both the temperature and hydrogen supply inside reaction chamber 6 reach a stable level. Once the state is established, the magnesium-based solid hydrogen storage material begins to react chemically with hydrogen. At this time, the data monitor 14 continuously monitors various key data during the reaction process in real time, including changes in hydrogen pressure, temperature fluctuations, and changes in material mass, and transmits this data to the data processor 2 in a timely manner. After receiving the data, the data processor 2 processes and analyzes the data efficiently according to a pre-set algorithm, accurately calculating important performance indicators such as the hydrogen absorption capacity, hydrogen release capacity, and hydrogen absorption / release rate of the material. Throughout the test, the pressure changes in the reaction chamber 6 are automatically adjusted through the exhaust pipe 22 to ensure that the reaction always proceeds in an orderly manner within a safe pressure range. The test is then completed.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
