Description

Technical Field

[0001] This utility model relates to the field of solid hydrogen storage and refueling technology, specifically to a leak-proof solid hydrogen storage and refueling device. Background Technology

[0002] Solid-state hydrogen storage is a hydrogen energy storage technology that converts hydrogen gas into solid metal hydrides through a chemical reaction, thereby achieving high-density, low-pressure, leak-free, and safe storage. Compared with traditional gaseous hydrogen storage systems, this technology has higher hydrogen storage density and lower operating pressure, improving storage efficiency and energy utilization. The advantages of solid-state hydrogen storage technology also include high-density hydrogen storage capacity, storage at normal temperature and pressure, good safety, and easy transportation, making the widespread application of solid-state hydrogen storage systems in the hydrogen energy industry possible, especially in the fields of automobiles, energy storage, and industrial manufacturing.

[0003] Solid-state hydrogen storage, as an important method of hydrogen storage, inevitably requires specialized refueling equipment. Current refueling equipment typically relies on specific pipeline systems to complete the hydrogen refueling operation. However, in actual long-term use, a very serious problem has gradually emerged: due to the unique chemical properties of hydrogen, in a solid-state hydrogen storage environment, the pipeline connections are continuously and persistently affected by the corrosion caused by hydrogen storage. This corrosion is not immediately noticeable but rather gradually erodes the material structure of the pipeline connections over a long period of time. As the corrosion deepens, the pipeline connections... The originally tight and reliable connection performance will gradually decline, leading to the destruction of its seal. Hydrogen can easily leak from these weak points. If the leak is minor, it may waste hydrogen and pose a certain safety hazard to the surrounding environment. In severe cases, such as when there are operators around the refueling site, the leaked hydrogen may spread rapidly and mix with the surrounding air to form a flammable mixture. Once it encounters a source of ignition or static electricity, it is very likely to cause a violent explosion or fire. This will undoubtedly cause extremely serious direct harm to the lives of the operators and may even lead to irreversible consequences. Utility Model Content

[0040] 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.

[0041] Please see Figures 1 to 4 A leak-proof solid hydrogen storage refueling device includes a refueling device body 1 with a cavity at its bottom. It also includes a pump 2, a delivery pipe 3, an output pipe 4, a refueling pipe 5, a refueling head 6, a sealing box 7, and a sealing mechanism. The pump 2 is installed inside the cavity. The delivery pipe 3 is connected to the input end of the pump 2. One end of the output pipe 4 is connected to the output end of the pump 2. The refueling pipe 5 is connected to the other end of the output pipe 4. The refueling head 6 is connected to the top end of the refueling pipe 5. The sealing box 7 is fixedly connected to one side of the refueling device body 1. Through the cooperation of the pump 2, delivery pipe 3, output pipe 4, refueling pipe 5, refueling head 6, sealing box 7, and sealing mechanism, the connection between the delivery pipe 3 and the refueling pipe 5 is effectively sealed, improving the sealing performance of the connection, effectively preventing hydrogen leakage, reducing safety hazards to the surrounding environment, and improving safety.

[0042] The sealing mechanism is located inside the sealing box 7 and is used to seal the connection between the output pipe 4 and the filling pipe 5. The sealing mechanism includes a rubber layer 8, a fixing plate 9, a clamping assembly, and a tensioning assembly. The rubber layer 8 is wrapped around the circumferential surface of the output pipe 4 and the filling pipe 5. Two fixing plates 9 are provided; one fixing plate 9 is fixedly connected to one end of the rubber layer 8, and the other fixing plate 9 has a sliding opening, in which the other end of the rubber layer 8 is slidably connected. Two clamping assemblies are provided, both located inside the sealing box 7, and are used to clamp the two fixing plates 9. The tensioning assembly is located inside the sealing box 7 and is used to tension the other end of the rubber layer 8. The clamping assembly includes a slide rod 10, a clamping plate 11, and a driving assembly. Two slide rods 10 are provided, both of which are... The sliding connection is on the sealing box 7, and the clamping plate 11 is fixedly connected to one end of the two slide rods 10. The drive assembly is set on one side of the sealing box 7 and is used to drive the two slide rods 10 to move. The drive assembly includes a drive plate 12 and a drive screw 13. The drive plate 12 is fixedly connected to the other end of the two slide rods 10, and the drive screw 13 is rotatably connected to one side of the sealing box 7. The drive plate 12 has a screw hole, and the drive screw 13 is threaded into the screw hole. Specifically, the operator rotates the hexagonal block 17 to drive the drive screw 13 to rotate. When the drive screw 13 rotates, it drives the drive plate 12 and the two slide rods 10 to move. When the slide rods 10 move, they drive the clamping plate 11 to abut against the fixed plate 9. The two clamping plates 11 move relative to each other, thereby stably clamping the two clamping plates 11.

[0043] The tensioning assembly includes a support plate 14, tensioning screws 15, and a tensioning plate 16. Hexagonal blocks 17 are fixedly connected to multiple tensioning screws 15 and two drive screws 13. The support plate 14 is fixedly connected to another fixed plate 9. Multiple tensioning screws 15 are rotatably connected to the bottom end of the support plate 14. The tensioning plate 16 is fixedly connected to the other end of the rubber layer 8. Multiple screw holes are provided on the tensioning plate 16, and the multiple tensioning screws 15 are threaded into these screw holes. Specifically, by rotating the hexagonal blocks 17, the operator drives the tensioning screws 15 to rotate, thereby causing the support plate 14 and the other end of the rubber layer 8 to descend, bringing the support plate 14 closer to the tensioning plate 16. This pulls the rubber layer 8 to slide within the sliding opening, thus tightening the rubber layer 8 between the delivery pipe 3 and the filling pipe 5 for sealing.

[0044] In summary, when the leak-proof solid hydrogen storage and refueling equipment needs to seal the connection between the delivery pipe 3 and the refueling pipe 5, the operator rotates the hexagonal block 17 to drive the drive screw 13 to rotate. When the drive screw 13 rotates, it drives the drive plate 12 and the two sliding rods 10 to move. When the sliding rods 10 move, they drive the clamping plate 11 to press against the fixed plate 9. The two clamping plates 11 move relative to each other, thus stably clamping the two clamping plates 11. Then, the operator rotates the hexagonal block 17 to drive the tensioning screw 15 to rotate, which in turn drives the support plate 14 and the other end of the rubber layer 8 to descend, so that the support plate 14 is close to the tensioning plate 16, thereby pulling the rubber layer 8 to slide in the sliding port, and thus tightening the rubber layer 8 between the delivery pipe 3 and the refueling pipe 5 to perform the sealing operation.

[0045] It should also be noted that a rubber filler block 18 is fixedly connected to one of the fixing plates 9, and the two rubber filler blocks 18 are located between the two ends of the rubber layer 8, thereby further improving the sealing performance of the rubber layer 8.
