Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, and more specifically, to a hydrogen gas sealing and collection device. Background Technology

[0002] Hydrogen is a flammable and explosive gas. During hydrogen production, storage, and use, if hydrogen leaks, it can easily mix with air to form a flammable mixture. Once it encounters a source of ignition or energy, it can cause an explosion. Hydrogen sealing and collection devices can effectively prevent hydrogen from leaking into the surrounding environment, reduce the risk of explosion, and ensure the safety of personnel and equipment. The most common hydrogen sealing and collection device is a hydrogen cylinder. The hydrogen cylinder is a key piece of equipment for sealing, collecting, and storing hydrogen. Because hydrogen has a very low density and a low volumetric energy density at normal temperature and pressure, the hydrogen cylinder can compress or liquefy hydrogen for storage, effectively increasing the storage density of hydrogen, thus facilitating the transportation, distribution, and use of hydrogen. Since the use of hydrogen cylinders is mainly controlled by the regulating valve on the top of the cylinder, it is necessary to perform protective operations on the hydrogen cylinder.

[0003] In related technologies, during the use of hydrogen tanks, an external gas pipe or other gas guiding component is generally connected to the hydrogen tank through a connector between the regulating valve and the regulating valve. Then, the regulating valve is rotated to change the sealing degree of the hydrogen tank and discharge the hydrogen, thus enabling its use.

[0004] However, in the current use of hydrogen tanks, since the regulating valve is generally located on the top of the hydrogen tank, during the movement and transfer of the hydrogen tank, if the staff accidentally touches it, or if the regulating valve comes into contact with external objects and rubs against them, it is easy for it to rotate, resulting in hydrogen leakage inside the hydrogen tank, which affects the sealing stability and safety of the hydrogen tank.

This provides the user with a means to protect the regulating valve 2 when it is idle, so that the user can perform sealing and protection work on the regulating valve 2 after operation, and avoid the situation where the regulating valve 2 is rotated by external force during use, which would cause the sealing degree of the regulating valve 2 to change and hydrogen leakage. Therefore, the sealing stability and safety of the tank 1 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the sealing and protective mechanism includes a protective plate 4, which is movably connected to the top of the regulating valve 2. A protective seat 5 is fixedly connected to the rear side of the top of the protective plate 4. A fixed seat 6 is movably connected to the top of the rear side of the lifting frame 3. A movable seat 7 is installed on the top of the front side inside the lifting frame 3. The fixed connection mechanism is located on the rear side of the top of the protective seat 5. The protective plate 4 is moved into the interior of the lifting frame 3 and positioned on top of the regulating valve 2. Then, the fixed seat 6 cooperates with the movable seat 7 to clamp and install the protective plate 4 inside the lifting frame 3, so that the protective plate 4 covers and protects the regulating valve 2, preventing the regulating valve 2 from contacting and rotating with external objects, thus preventing leakage. The sealing degree is changed to ensure the sealing performance of the regulating valve 2. The fixed connection mechanism includes a connecting groove 8, a connecting head 9, and a connecting rod 10. The connecting groove 8 is opened on the rear side of the top of the protective seat 5. The connecting head 9 is movably connected to the inside of the connecting groove 8 through a shaft pin. The connecting rod 10 is fixedly connected to the rear side of the connecting head 9. The top of the fixed seat 6 is fixedly connected to the rear side of the bottom of the connecting rod 10.

This avoids the situation where the protective plate 4 is difficult to connect to the fixed seat 6 or cannot be flipped during use, thus improving the connection effect and connection flexibility between the protective plate 4 and the fixed seat 6.

[0032] Reference Figures 2-4In a preferred embodiment, magnetic rings 11 are embedded and connected to both sides of the inner wall of the connecting groove 8, and magnetic suction rings 12 connected to the magnetic rings 11 are embedded and connected to both sides of the connecting head 9.

Therefore, the connection effect between the movable seat 7 and the connecting rod 10 is improved.

[0033] Reference Figures 2-3 In a preferred embodiment, a screw hole 15 is provided inside the slider 14, and a stud 16 is threadedly connected inside the screw hole 15. The front side of the stud 16 is connected to the slide groove 13. The slider 14 can apply a sliding adjustment force to the movable seat 7, avoiding the situation where the movable seat 7 is difficult to adjust during use. Therefore, the adjustment and use of the movable seat 7 is improved. A rotating groove 17 is provided on the front side of the inner wall of the slide groove 13.

The rear side of the rotating frame 18 is fixedly connected to the front side of the stud 16, which can rotate the stud 16 and the slide groove 13 to avoid the stud 16 from separating from the slide groove 13 during use. Therefore, the use stability of the stud 16 is improved.

[0034] Reference Figures 2-3 In a preferred embodiment, a force-applying hole 19 is provided on the rear side inside the slide groove 13.

Therefore, the ease of use of the stud 16 is improved. A magnetic cylinder 21 is embedded and connected to the surface of the force-applying column 20. A magnetic suction cylinder 22 that is magnetically connected to the magnetic cylinder 21 is fixedly connected to the inner wall of the force-applying hole 19.

Therefore, the positioning convenience of the stud 16 is improved.

[0035] Specifically, the working process or working principle of this hydrogen sealing collection device is as follows: During use, the connecting rod 10 is moved to the rear of the top of the lifting frame 3, positioning the top of the lifting frame 3 between the fixed seat 6 and the movable seat 7. This prepares for the movable seat 7 to cooperate with the fixed seat 6 to clamp the lifting frame 3. The protective plate 4 is positioned inside the lifting frame 3 and on top of the regulating valve 2. Then, using an external hex wrench, the force-applying column 20 is rotated through the hexagonal groove on its rear side. This causes the force-applying column 20 to drive the stud 16 to rotate, passing through the screw hole 15 and engaging with the slider 14. This applies a sliding thrust to the movable seat 7, causing the movable seat 7 to cooperate with the fixed seat 6 and the connecting rod 10 to clamp and install the protective plate 4 on top of the regulating valve 2. At this time, the rotating frame 18 follows the stud 16 as it rotates inside the rotating groove 17, performing a rotational connection between the stud 16 and the sliding groove 13. Simultaneously, the slider 14 provides sliding guidance between the movable plate and the connecting rod 10 during movement. When the force-applying column… After use, the magnetic cylinder 21, in conjunction with the magnetic suction cylinder 22, uses the force-applying column 20 to magnetically position the stud 16 and the connecting rod 10, ensuring the stability of the stud 16. This allows the fixed seat 6, in conjunction with the movable seat 7, to stably clamp the connecting rod 10 and the lifting frame 3. When the regulating valve 2 needs to be used, the protective plate 4 is flipped upwards by hand. At this time, the connector 9 rotates inside the connecting groove 8, and the protective seat 5 connects the protective plate 4 and the connecting rod 10. Simultaneously, the magnetic ring 11, in conjunction with the magnetic suction ring 12, uses the connector 9 and the protective seat 5 to magnetically position the flipped protective plate 4 and the connecting rod 10, allowing the regulating valve 2 to be opened and the hydrogen gas inside the tank 1 to be used. After the regulating valve 2 is used, the protective plate 4 is flipped downwards by hand to reset it, so that the protective plate 4 covers the top of the regulating valve 2, providing protection.

[0036] It should be noted that the tank body 1, the regulating valve 2 and the lifting frame 3 are all 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.
