[0002] Hydrogen, a colorless, odorless, and non-toxic gas with the chemical formula H2, is the lightest and most abundant element in the universe. It is a gas at room temperature and pressure and is highly flammable. It is widely used in industries such as ammonia production, petroleum refining, and metal processing. Hydrogen is also seen as a potential source of clean energy, capable of powering fuel cells and reducing greenhouse gas emissions. Due to its lightweight properties, hydrogen also has applications in aerospace and balloon manufacturing.

[0003] After hydrogen is produced, it is usually collected in hydrogen tanks. However, during transportation, if the road is bumpy, the bottles are prone to collision, causing the bottle mouth connection to loosen, resulting in gas leakage and explosion due to the violent shaking of the hydrogen tank under severe bumps. The structure of traditional hydrogen tanks is similar to that of gas tanks, and there is no corresponding warning and prompt structure after leakage. Therefore, when traditional hydrogen tanks are transported and used, staff cannot quickly understand the situation and maintain them, which poses obvious safety hazards.

[0004] Therefore, the present invention proposes a hydrogen collection device to solve the above problems existing in the existing hydrogen tanks. Utility Model Content

[0044] Example 1:

[0045] As the instruction manual Figure 1-Figure 7 As shown, the utility model provides a technical solution:

[0046] A hydrogen collection device comprises a frame 1, wherein a plurality of gas cylinders 2 are installed in a rectangular array in the inner cavity of the frame 1, wherein the surface of the gas cylinder 2 is connected to a valve 4, and the gas outlet end of the valve 4 is connected to a connecting pipe 5; and a sealing component 3, wherein the sealing component 3 is arranged at the surface of the gas cylinder 2 at the filling and exhaust port.

[0047] It should be noted that in this embodiment, the frame 1 is provided to facilitate the restraint of the gas cylinder 2, forming an integrated device capable of collecting hydrogen during the hydrogen production process. The sealing assembly 3 is provided to seal the connecting pipe 5, thereby achieving the collection and sealing of hydrogen during the hydrogen production process.

[0048] Example 2:

[0049] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7As shown, the sealing assembly 3 includes a sealing shell 301 fixedly connected to the upper end surface of the gas cylinder 2, a slide groove 305 is provided at the bottom of the inner cavity of the sealing shell 301, a movable plate 302 is slidably connected to the inner cavity of the sealing shell 301, and a movable shell 304 is fixedly connected to the surface of the movable plate 302. The interior of the movable shell 304 is movably connected to an adjusting rod 310 through a rotating shaft, and the end of the adjusting rod 310 away from the movable plate 302 is movably connected to a sealing ring 306 through a rotating shaft. The side of the sealing ring 306 close to the valve 4 is in contact with the gas cylinder plug 401 of the valve 4, and a cylinder 303 is also fixedly connected to the inner cavity of the sealing shell 301, and the piston end of the cylinder 303 is fixedly connected to the movable plate 302. The two sealing rings 306 are driven to move toward or away from each other through the expansion and contraction of the cylinder 303.

[0050] A plurality of springs 307 are fixedly connected to the surface of the movable plate 302 , and a side of the spring 307 close to the inner wall of the sealing shell 301 is fixedly connected to the inner wall of the sealing shell 301 .

[0051] The surface of the sealing ring 306 is fixedly connected to a sliding seat 311 . The surface of the sliding seat 311 is slidably connected to the inner cavity of the sliding groove 305 , and the movement of the sliding seat 311 is guided by the sliding groove 305 .

[0052] A through opening is further provided on one side of the surface of the sealing shell 301 , and the inner cavity of the through opening is connected to a pressure gauge 308 through a sealing ring 306 , and the pressure gauge 308 is arranged in a bent shape.

[0053] The movable plate 302 is located at the top of the inner cavity of the sealing shell 301 , and the inner cavity thereof is slidably connected to the pipe portion of the valve 4 .

[0054] A detector 309 is provided on the other side of the surface of the sealed shell 301 , and the detector 309 includes a hydrogen sensor.

[0055] like Figure 7 As shown, in this embodiment, detector 309 includes a microcontroller, a hydrogen sensor connected to the microcontroller input, and a parameter input module. The microcontroller output is connected to an alarm and a relay module. The relay module is connected to cylinder 303. Detector 309 is mounted at the gas inlet and outlet on the upper end of gas cylinder 2 and can be installed by strapping or other removable means. The hydrogen sensor is exposed from the detector 309 housing and is located at the gas inlet and outlet on the upper end of gas cylinder 2.

[0056] The hydrogen sensor can detect the hydrogen concentration at the gas inlet and outlet at the upper end of the gas cylinder 2 in real time. When the hydrogen concentration detected by the hydrogen sensor exceeds the preset threshold value set by the parameter input module, it is determined to be a hydrogen leak. At this time, the microcontroller will generate a control pulse to the alarm and relay module. The alarm sounds an alarm to alert the staff to reduce the risk of leakage. The relay module is powered and works, thereby controlling the piston end of the cylinder 303 to extend downward, so that the two flexible sealing rings 306 move toward each other, pressing tightly against the gas cylinder plug 401 and the gas inlet and outlet at the upper end of the monitoring gas cylinder 2. The sealing ring 306 seals the interface between the valve 4 and the gas cylinder 2 to prevent leakage at the upper end outlet of the gas cylinder 2.

[0057] It should be noted that, in this embodiment, the gas cylinder 2, gas cylinder 303, barometer 308, detector 309, control system, etc. described above are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs and will not be described in detail here.

[0058] Example 3:

[0059] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the valve 4 also includes a valve core screw 402 and a valve body sleeve 403. The valve core screw 402 is threadedly connected to the valve body sleeve 403, and a valve plug 404 is provided at the lower end of the valve core screw 402 for use in conjunction with the inner cavity of the valve body sleeve 403. The connecting pipe 5 is connected to the valve body sleeve 403.

[0060] It should be noted that in this embodiment, the valve plug 404 is a flexible rubber structure. The valve core screw 402 drives the valve plug 404 to move within the valve body sleeve 403. When the valve plug 404 is rotated and adjusted to be higher than the connection point of the connecting pipe 5, hydrogen is filled and released into the gas cylinder 2. When the valve plug 404 is rotated and adjusted to be lower than the connection point of the connecting pipe 5, the hydrogen inside the gas cylinder 2 is sealed.

[0061] When the hydrogen collection device for hydrogen production process of the utility model is used:

[0062] During the process of methane cracking to produce hydrogen, the staff injects the prepared hydrogen into the interior of the gas cylinder 2 for collection, and then places multiple gas cylinders 2 in sequence into the interior of the frame 1. The size of the frame 1 is just enough to accommodate four groups of gas cylinders 2, with four gas cylinders 2 in each group. The length and width of the frame 1 are consistent, which can effectively limit the four groups of gas cylinders 2 and effectively reduce the gaps between the gas cylinders 2. At the same time, it also reduces the swing amplitude of the gas cylinder 2 during bumps, which can have a certain pressure resistance effect and avoid explosions under severe shaking. Subsequently, when the gas cylinder 2 is transported, if hydrogen leaks from the gas cylinder 2, the gas pressure in the gas cylinder 2 will change, and the detector 309 will detect the hydrogen at the first time. When the hydrogen concentration exceeds the preset value, the detector 309 controls the cylinder 303 to press down. At this time, the piston end of the cylinder 303 presses the adjusting rod 310 downward through the movable plate 302. Since the adjusting rod 310 is arranged at an angle, when the movable plate 302 is pressed down, the two adjusting rods 310 drive the sealing rings below them to approach each other until the inner cavity of the sealing ring contacts the interface of the valve 4. At this time, the connection between the valve 4 and the gas cylinder 2 can be blocked. At the same time, the detector 309 will also sound an alarm through its built-in alarm to remind the staff that hydrogen leakage has occurred in this gas cylinder 2, and the staff can come for maintenance at this time.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
