Description

Technical Field

[0001] This utility model belongs to the field of hydrogen storage technology, and in particular relates to a hydrogen storage device. Background Technology

[0002] High-pressure gaseous hydrogen storage cylinders are one of the most widely used technical equipment in the field of hydrogen energy storage. Their core principle is to pressurize hydrogen to a high pressure of 35MPa (350 bar) or 70MPa (700 bar) through a special compression device, and then use a container with high strength and resistance to hydrogen embrittlement (commonly with a metal or polymer inner liner and an outer layer of carbon fiber composite material) to achieve sealed storage of hydrogen.

[0003] Because the valve of a high-pressure gaseous hydrogen storage cylinder is relatively narrow and fragile, it is very easy to be damaged and leak gas after being impacted by external force. In addition, the valve of a conventional high-pressure gaseous hydrogen storage cylinder lacks a barrier protection, which makes the valve of a conventional high-pressure gaseous hydrogen storage cylinder relatively fragile.

[0004] Therefore, we propose a hydrogen storage device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of the vulnerability of the valve in conventional high-pressure gaseous hydrogen storage cylinders, and to propose a hydrogen storage device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A hydrogen storage device includes a high-pressure gaseous hydrogen storage cylinder. A protective railing is fixedly connected to the upper part of the high-pressure gaseous hydrogen storage cylinder. A protective cover is inserted into the upper part of the protective railing. Spring-loaded buckles are symmetrically fixedly connected to the sides of the protective cover, and the lower parts of the spring-loaded buckles engage with the protective railing. When the high-pressure gaseous hydrogen storage cylinder is dropped or collides with other objects, the protective railing and protective cover block the gas valve of the high-pressure gaseous hydrogen storage cylinder, preventing damage and leakage, improving impact resistance, and increasing the safety factor.

[0007] Preferably, the upper end of the protective cover is threaded with a first stop cover. The first stop cover, positioned above the protective cover, prevents objects from impacting the valve of the high-pressure gaseous hydrogen storage cylinder from above, thus facilitating further protection of the high-pressure gaseous hydrogen storage cylinder when it is not in use.

[0008] Preferably, a second cover is threadedly installed at the opening between the guardrail and the protective cover. The second cover blocks the opening of the guardrail and the protective cover, preventing objects from passing through and impacting the valve of the high-pressure gaseous hydrogen storage cylinder, thus facilitating further protection of the high-pressure gaseous hydrogen storage cylinder when not in use.

[0009] Preferably, the guardrail includes a guardrail body, with a limiting rotating strip fixedly connected inside the guardrail body, a first threaded guardrail fixedly connected to the front of the guardrail body, and a fastening groove on the outside of the guardrail body. The limiting rotating strip is used to engage the protective cover to prevent rotation, and the fastening groove is used to engage the spring buckle.

[0010] Preferably, the spring clip includes a connecting plate, with a spring piece fixedly connected to the lower end of the connecting plate, and a fastening block fixedly connected to the lower end of the spring piece. The fastening block engages with a fastening groove, and a lever is fixedly connected to the lower outer part of the spring piece. Pulling the lever outward causes the spring piece to deform outward, disengaging the fastening block from the fastening groove, opening the protective cover, and then installing the high-pressure gaseous hydrogen storage cylinder and pipeline. After installation, the protective railing and protective cover are reconnected for easy opening and closing.

[0011] Preferably, the protective cover includes a threaded nozzle, a second threaded rail is fixedly connected to the front of the threaded nozzle, the second cover is threadedly matched with the first and second threaded rails, and a plug-in plate is fixedly connected to the lower inner end of the threaded nozzle. The plug-in plate is inserted into the guardrail body, the rotation limiting strip is slidably engaged with the plug-in plate, and the connecting plate is fixedly connected to the threaded nozzle. When the plug-in plate is inserted into the guardrail body, the rotation limiting strip is engaged with the plug-in plate, causing the second and first threaded rails to close into a ring shape. The threaded nozzle, with its spring-loaded buckle, engages with the protective guardrail, thus protecting the upper part of the high-pressure gaseous hydrogen storage cylinder by blocking its upper side.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. When a high-pressure gaseous hydrogen storage cylinder is knocked over or collides with other objects, use guardrails or protective covers to block the gas valve of the high-pressure gaseous hydrogen storage cylinder to prevent it from being damaged and leaking, thereby improving its impact resistance and safety factor.

[0013] 2. The first cover is placed on the upper side of the protective cover to prevent objects from hitting the valve of the high-pressure gaseous hydrogen storage cylinder from above, which facilitates further protection of the high-pressure gaseous hydrogen storage cylinder when it is not in use.

[0014] 3. Pull the lever outwards. The lever will act outwards on the spring, causing the lower part of the spring to deform outwards, disengaging the buckle from the buckle groove, opening the protective cover. Then install the high-pressure gaseous hydrogen storage cylinder and pipeline. After installation, reconnect the guardrail and protective cover to facilitate opening or closing of the guardrail and protective cover. Attached Figure Description

Pulling the lever 34 outward causes the lever 34 to act outward on the spring piece 32, causing the lower part of the spring piece 32 to deform outward, thus disengaging the fastening block 33 from the fastening groove 24. This opens the protective cover 4, allowing the high-pressure gaseous hydrogen storage cylinder 1 and pipeline to be installed. After installation, the protective railing 2 and the protective cover 4 are reconnected.

[0023] like Figure 1 , 2 As shown in Figures 3 and 4, the protective cover 4 includes a threaded nozzle 41. A second threaded rail 43 is fixedly connected to the front of the threaded nozzle 41. The second cover 6 is threadedly matched with the first threaded rail 23 and the second threaded rail 43. A plug-in plate 42 is fixedly connected to the lower inner end of the threaded nozzle 41. The plug-in plate 42 is inserted into the guardrail body 21. The rotation limiting strip 22 is slidably engaged with the plug-in plate 42. The connecting plate 31 is fixedly connected to the threaded nozzle 41. When the plug-in plate 42 is inserted into the guardrail body 21, the rotation limiting strip 22 is engaged with the plug-in plate 42, and the second threaded rail 43 and the first threaded rail 23 are closed to form a ring. The threaded nozzle 41 is fastened to the protective guardrail 2 through the spring buckle 3. The threaded nozzle 41 blocks the upper side of the high-pressure gaseous hydrogen storage cylinder 1, protecting the upper part of the high-pressure gaseous hydrogen storage cylinder 1.

[0024] Working principle: When the high-pressure gaseous hydrogen storage cylinder 1 is knocked over or collides with other objects, the protective railing 2 and protective cover 4 are used to block the gas valve of the high-pressure gaseous hydrogen storage cylinder 1 to prevent the high-pressure gaseous hydrogen storage cylinder 1 from being damaged and leaking.
