Abstract
Description
Technical Field
[0001] The utility model relates to the field of high-pressure hydrogen pipeline leakage combustion experiments, in particular to a high-pressure hydrogen pipeline leakage combustion experiment device. Background Technique
[0002] High-pressure hydrogen, as an efficient and clean energy carrier, has attracted much attention in the energy field in recent years. By compressing hydrogen to a high-pressure state, the storage and transportation efficiency is significantly improved. As a fuel, hydrogen has an extremely high calorific value of combustion, and the combustion product is only water, without generating greenhouse gases and other pollutants. Therefore, it is regarded as one of the important options for achieving the goal of carbon neutrality in the future.
[0003] However, there are also many safety problems in the use of high-pressure hydrogen. First of all, the compression and storage of hydrogen require high-pressure conditions, which pose extremely high requirements on the material, sealing performance and safety performance of the storage container. The transportation of hydrogen requires special pipelines or vehicles, and it is necessary to ensure that no leakage occurs during transportation to ensure public safety.
[0004] Therefore, the high-pressure hydrogen pipeline leakage combustion experiment device is very important. Although some high-pressure hydrogen pipeline leakage combustion experiment devices can simulate hydrogen leakage and observe its combustion time, these devices are often limited to the indoor environment and ignore the external conditions that may be faced in actual applications, such as the influence of different wind speeds and wind directions on the hydrogen leakage diffusion and combustion characteristics. In the outdoor environment, the changes in wind speed and wind direction will directly affect the diffusion speed, direction and range of hydrogen, thereby affecting the intensity and influence area of the combustion reaction.

Detailed Description of the Preferred Embodiments
[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.
[0016] Please refer to Figures 1-3, the present utility model provides a technical solution: a high-pressure hydrogen pipeline leakage combustion experimental device, which includes an experimental chamber 10. One side of the experimental chamber 10 is communicated with a pipeline 11, and the pipeline 11 is connected to a gas tank 12. An experimental pipeline 14 is horizontally and fixedly arranged inside the experimental chamber 10, and the experimental pipeline 14 is communicated with the pipeline 11. A first moving groove 20 is opened on one side inside the experimental chamber 10. A lead screw 21 is rotatably arranged inside the first moving groove 20. A moving block 22 is movably installed on the periphery of the lead screw 21. An arc-shaped plate 23 is fixedly arranged on one side of the moving block 22. A second installation groove 24 is opened inside the arc-shaped plate 23. A gear 25 is arranged inside the second installation groove 24. A second moving groove 26 is opened on one side of the arc-shaped plate 23. A moving plate 27 is movably installed inside the second moving groove 26. A back gear 28 is arranged on the back side of the moving plate 27. The back gear 28 meshes with the gear 25. A plurality of air outlet devices 29 are arranged on one side of the moving plate 27.
[0017] In this implementation scheme, through the pipeline 11 connecting the experimental pipeline 14 in the experimental chamber 10 with the gas tank 12, the real state of high-pressure hydrogen in daily actual pipelines can be simulated. Inside the first moving groove 20 opened on one side inside the experimental chamber 10, the lead screw 21 is driven to rotate by a motor, driving the moving block 22 to move along the direction of the lead screw 21 inside the first moving groove 20. The arc-shaped plate 23 fixedly arranged on one side of the moving block 22 can adjust its position as the moving block 22 moves. The gear 25 is arranged inside the second installation groove 24 opened inside the arc-shaped plate 23 and meshes with the back gear 28 on the back side of the moving plate 27 inside the second moving groove 26, allowing the moving plate 27 to move along a certain track on the arc-shaped plate 23, increasing the flexibility and adjustability of the experimental device. The plurality of air outlet devices 29 arranged on one side of the moving plate 27 can adjust their positions and angles according to experimental requirements to simulate the influence of different wind speeds and wind directions on hydrogen leakage combustion.
[0018] Specifically, a limiting groove 18 is opened inside the upper semi-circular arc of the experimental chamber 10. A limiting block is arranged inside the limiting groove 18. The arc-shaped plate 23 is fixedly connected to the limiting block.
[0019] In this implementation scheme, through the combination of the limiting groove 18 and the limiting block, additional support and guidance are provided during the movement of the arc-shaped plate 23, effectively preventing the arc-shaped plate 23 from shifting, shaking or tilting during movement, thereby ensuring the accuracy and stability of hydrogen leakage simulation during the experimental process.
[0020] Specifically, a first installation groove 15 is opened on the upper semi-circular arc of the experimental chamber 10. An observation mirror 16 is installed inside the first installation groove 15. The observation mirror 16 is fixed to the experimental chamber 10 through a fixing bolt 17.
[0021] In this embodiment, an installation groove 15 is provided in the upper semi-circular part of the experimental chamber 10 to ensure the stable installation of the observation mirror 16. The observation mirror 16 is embedded inside the installation groove 15 and tightly fixed to the experimental chamber 10 by fixing bolts 17, making the observation mirror 16 both stable and convenient for disassembly and maintenance, so that the experimental personnel can clearly observe the whole process of hydrogen leakage and combustion without being directly exposed to the high-pressure hydrogen environment inside the experimental chamber 10.
[0022] Specifically, a discharge port 13 is provided on one side of the experimental chamber 10.
[0023] In this embodiment, due to the existence of the discharge port 13, the gas inside the experimental chamber 10 can be quickly and safely discharged into the external environment when needed, which helps to prevent the explosion risk caused by too high gas concentration inside the experimental chamber 10, thus ensuring the safety of the experimental personnel and experimental equipment. When conducting multiple experiments or continuously observing experimental phenomena, the discharge port 13 can conveniently discharge the gas generated in the previous experiment from the experimental chamber 10, creating a clean and safe experimental environment for the next experiment or continuous observation, which helps to improve the experimental efficiency and reduce the experimental preparation time.
[0024] Specifically, the interior of the experimental chamber 10 is a circular space, and the arc-shaped plate 23 is designed as a semi-circle.
[0025] In this embodiment, by designing the interior of the experimental chamber 10 as a circular space, it is beneficial to the uniform distribution and flow of gas, and can also reduce the possibility of gas accumulation in corners or dead ends, thus improving the safety and accuracy of the experiment. The arc-shaped plate 23 adopts a semi-circular design, which enables the arc-shaped plate 23 to closely fit the inner wall of the experimental chamber 10 and makes its movement smoother.
[0026] The working principle and usage process of the present utility model are as follows: First, high-pressure hydrogen is filled into the experimental pipeline 14 inside the experimental chamber 10 through the gas cylinder 12. Subsequently, the motor is started to drive the screw rod 21 to rotate, driving the arc-shaped plate 23, the moving plate 27 thereon, and the air outlet device 29 to the predetermined position, and the air outlet device 29 is adjusted to simulate the required wind speed and direction. During the experiment, the hydrogen leakage and combustion conditions are observed through the observation mirror 16. After the experiment is completed, the discharge port 13 is opened to discharge the gas inside the experimental chamber 10 to ensure safety. The whole process is flexibly adjustable, efficient and safe.
[0027] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
