Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy production and manufacturing technology, and more specifically, to a hydrogen refueling device for hydrogen energy production. Background Technology

[0002] Hydrogen refueling equipment for hydrogen production is a crucial piece of equipment used to fill hydrogen storage devices or other hydrogen application equipment with hydrogen. A typical hydrogen refueling system consists of the following main components: a hydrogen storage system (responsible for storing hydrogen, which can be stored in high-pressure gas, liquid, or solid form, and the storage system must possess sufficient safety and stability); a refueling station control system (used to monitor and control various parameters during the refueling process, such as temperature, pressure, and flow rate, ensuring the safety and efficiency of the refueling process); a refueling pump and flow meter (used to deliver the stored hydrogen to the refueling port and accurately measure the amount of hydrogen refueled); a connection device and refueling nozzle (the hydrogen is connected to the vehicle's hydrogen storage tank via this device, typically including specially designed connectors and a refueling nozzle to ensure a safe and convenient refueling process); and a safety monitoring system (with functions such as leak detection, pressure monitoring, and temperature monitoring, ensuring timely handling of any abnormalities during the refueling process). Since the hydrogen refueling equipment mainly completes the hydrogen refueling operation through control switches, it is necessary to implement protective measures for the control switches of the hydrogen refueling equipment.

[0003] In related technologies, during the use of hydrogen refueling equipment, the operator typically operates the corresponding control switch to perform the hydrogen refueling operation based on the actual hydrogen refueling situation and operational needs.

[0004] However, in the current use of hydrogen refueling equipment, since the control switches of hydrogen refueling equipment are generally located on the outside, after the staff has finished operating, it is very easy for external objects or staff to accidentally touch the control switches and turn them on, which may lead to malfunction of the control switches of hydrogen refueling equipment, or even hydrogen leakage, affecting the stability and safety of the operation of hydrogen refueling equipment.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a hydrogen refueling device for hydrogen energy production, including a hydrogen refueling device body 1 and an operation protection mechanism. A pressure gauge 2 is installed on the top front side of the hydrogen refueling device body 1, and a control switch 3 is installed on the front side of the top of the hydrogen refueling device body 1. The control switch 3 can be covered and protected when not in use to prevent it from being affected by external objects or unintentional touch by personnel, which could lead to erroneous operation and hydrogen leakage inside the hydrogen refueling device body 1. Therefore, the stability and safety of the operation of the hydrogen refueling device body 1 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the operating protective mechanism includes a protective frame 4, which is movably connected to the front of the top of the hydrogen refueling device body 1. Connecting posts 5 are fixedly connected to the bottom of both sides of the protective frame 4. A connecting plate 6 is movably connected to the bottom of the connecting posts 5. A connecting pad 7, which contacts the hydrogen refueling device body 1, is fixedly connected to the inner side of the connecting plate 6. A protective closing mechanism is movably connected inside the protective frame 4. By holding the protective frame 4 and moving the front of the top of the hydrogen refueling device body 1, the protective frame 4 covers the outside of the control switch 3. Moving the connecting plate 6 causes the connecting pad 7 to contact and press firmly against the hydrogen refueling device body 1, so that the connecting plate 6, in conjunction with the connecting pad 7, passes through the connecting posts 5, thus protecting the protective frame 4 from the hydrogen refueling device body 1. The gas filling equipment body 1 is connected and works stably, so that the protective frame 4 is stable on the top of the hydrogen filling equipment body 1, and covers and protects the control switch 3. The protective closing mechanism includes a closing frame 8, a closing strip 9 and a closing plate 10. The closing frame 8 is movably connected inside the protective frame 4, the closing strip 9 is fixedly connected to the front side of the top of the inner wall of the closing frame 8, and the closing plate 10 is movably connected to the front side of the closing strip 9. It can provide the user with a medium to expand the protective coverage area of ​​the protective frame 4 and a medium to close the protective frame 4, so as to avoid the situation that the protective frame 4 is difficult to expand and close during use, thus improving the flexibility of use and protective closure of the protective frame 4.

[0032] Reference Figures 2-3In a preferred embodiment, lifting ports 11 are provided on both sides of the front side of the closing plate 10. A lifting seat 12 is movably connected inside the lifting port 11. The rear side of the lifting seat 12 is fixedly connected to the front side of the closing strip 9. This allows for lifting and connecting the closing plate 10 and the closing strip 9 to prevent separation, thus improving the stability of the closing plate 10. Magnetic strips 13 are embedded on both sides of the inner wall of the lifting port 11, and magnetic suction strips 14, which are magnetically connected to the magnetic strips 13, are embedded on both sides of the lifting seat 12. This allows for magnetic positioning of the closing plate 10 and the closing strip 9 after lifting, thus improving the ease of positioning the closing plate 10.

[0033] Reference Figures 2-4 In a preferred embodiment, by providing translation openings 15 on both sides of the protective frame 4, and magnetically connecting translation frames 16 inside the translation openings 15, and fixing the inner side of the translation frames 16 to the outer side of the closed frame 8, the connection between the closed frame 8 and the protective frame 4 can be extended and prevented from separating, thus improving the connection effect between the closed frame 8 and the protective frame 4. A sliding groove 17 is provided at the bottom of the connecting post 5, and a sliding plate 18 is movably connected inside the sliding groove 17. The bottom of the sliding plate 18 is fixedly connected to the top of the connecting plate 6, which can prevent the connecting plate 6 and the connecting post 5 from sliding and prevent them from falling off, thus improving the sliding stability of the connecting plate 6 and the connecting post 5.

[0034] Reference Figure 4 In a preferred embodiment, a screw hole 19 is provided inside the slide plate 18, and a stud 20 is threadedly connected inside the screw hole 19. The outer side of the stud 20 extends to the outer side of the connecting post 5. The slide plate 18 can apply a sliding and pressing force to the connecting plate 6, thus improving the convenience of sliding force application to the connecting plate 6. A rotating groove 21 is provided on the inner side of the inner wall of the slide groove 17. A rotating seat 22 is magnetically connected inside the rotating groove 21. The outer side of the rotating seat 22 is fixedly connected to the inner side of the stud 20, which can perform a rotating connection between the stud 20 and the connecting post 5, thus improving the connection stability between the stud 20 and the connecting post 5.

[0035] Specifically, the working process or principle of this hydrogen refueling equipment for hydrogen production is as follows: During use, first, hold the protective frame 4 and move it to the top of the hydrogen refueling equipment body 1. At this time, the closing frame 8 moves along with the protective frame 4 to the top of the hydrogen refueling equipment body 1 through the translation port 15 and the translation frame 16, positioning the protective frame 4 and the closing frame 8 outside the control switch 3. This prepares for the subsequent protection of the control switch 3 by the protective frame 4 and the closing frame 8. Then, according to the actual protection range requirements of the control switch 3, hold the closing frame 8 and move it forward to expand the protection range of the protective frame 4. The operation ensures that the coverage area of ​​the bottom of the protective frame 4 and the closed frame 8 meets the coverage and protection requirements of the control switch 3. At this time, the translation frame 16 follows the closed frame 8 inside the translation port 15 to perform translational connection between the closed frame 8 and the protective frame 4. Subsequently, the hand-held stud 20, in conjunction with the screw hole 19, applies an inward threaded thrust to the connecting plate 6 through the slide plate 18, causing the connecting plate 6 to drive the connecting pad 7 to move inward and contact the hydrogen filling equipment body 1, thus connecting and securing the protective frame 4 with the hydrogen filling equipment body 1. During this process, the rotating seat 22 follows the stud. 20 rotates inside the rotating groove 21, providing rotational support between the stud 20 and the connecting column 5, ensuring the stability of the stud 20 when it engages with the screw hole 19 to push the slide plate 18. When it is necessary to operate the hydrogen refueling equipment body 1 for hydrogen refueling via the control switch 3, the closing plate 10 is moved upwards to open the front of the closing frame 8, allowing operation of the control switch 3 covered by the bottom of the closing frame 8 and the protective frame 4. Since both the protective frame 4 and the closing frame 8 are made of transparent acrylic, the operator can observe the control switch 3 through the protective frame 4 and the closing frame 8 to operate the control switch 3. After the operation of the control switch 3 is completed, the closing plate 10 is moved downward by hand to close the front of the closing frame 8 and the protective frame 4. During this process, the lifting seat 12 moves through the lifting port 11 and passes through the closing strip 9 to connect the closing plate 10 and the closing frame 8. At the same time, the magnetic strip 13 and the magnetic suction strip 14 pass through the lifting seat 12 to magnetically position the closed plate 10 after lifting, so that the closing plate 10 stably closes the closing frame 8 and the protective frame 4, and the protective frame 4 and the closing frame 8 cover and protect the control switch 3.

[0036] It should be noted that the hydrogen refueling equipment body 1, pressure gauge 2 and control switch 3 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
