For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] At present, hydrogen production and hydrogen refueling systems are generally two independent systems, which need to rely on long-tube trailers and other transportation equipment to transport hydrogen. This method has the problems of high safety risks, low transportation efficiency and high cost.

[0054] Based on this, the following embodiments are proposed.

[0055] Embodiment 1:

[0056] like Figure 1 As shown, this embodiment provides a distributed off-grid hydrogen production and hydrogenation integrated system, including:

[0057] A transmission platform 1, on which a shell 2 is disposed, and a transmission space is formed between the shell 2 and the transmission platform 1;

[0058] Photovoltaic assembly, the photovoltaic assembly includes a photovoltaic panel 301, the photovoltaic panel 301 is arranged on the housing 2, and the photovoltaic panel 301 is used to receive sunlight so that the photovoltaic assembly converts solar energy into electrical energy for storage and output;

[0059] A hydrogen production device 4 is arranged on the transmission platform 1. The hydrogen production device 4 moves in the transmission space during the transmission process of the transmission platform 1. The photovoltaic module provides electric energy for the hydrogen production device 4.

[0060] The hydrogenation assembly is arranged on the top wall of the shell 2. When the hydrogen production device 4 moves in the transmission space to be opposite to the hydrogenation assembly, the input end of the hydrogenation assembly is connected with the output end of the hydrogen production device 4 to form a hydrogenation passage.

[0061] In this embodiment, the transmission space for the hydrogen production device 4 is formed by designing the transmission platform 1 and the housing 2. Shanghai 2024-11484 (M240573CNI)

[0062] The transmission platform 1 can be a belt conveyor, which can continuously transmit the hydrogen production device 4 to the transmission space opposite to the hydrogenation component. The input end of the hydrogenation component is connected with the output end of the hydrogen production device 4 to form a hydrogenation passage, so that the hydrogen generated in the hydrogen production device 4 is directly transmitted to the outside through the hydrogenation passage. A corresponding high-pressure storage tank for storing hydrogen can be set outside to receive and store hydrogen, thereby forming a distributed off-grid hydrogen production and hydrogenation integrated system, realizing orderly connection between hydrogen production and hydrogenation, effectively improving hydrogen production efficiency, and reducing transportation risks.

[0063] Specifically, the hydrogen production method in the hydrogen production device 4 is to produce hydrogen by electrolysis of water. The raw materials required for hydrogen production by electrolysis of water are pre-filled into the hydrogen production device 4. After the filling is completed, the hydrogen production device 4 is placed at the entrance of the transmission platform 1, and the transmission platform 1 works to transmit the hydrogen production device 4 to a position opposite to the hydrogenation component. At this time, the input end of the hydrogenation component is connected with the output end of the hydrogen production device 4 to form a hydrogenation path, and the hydrogen production device 4 is started to start hydrogen production. The distributed off-grid formed by the photovoltaic component becomes the hydrogen production device 4 to provide the electric energy required for its hydrogen production. Therefore, the distributed off-grid hydrogen production and hydrogenation integrated system can realize the conversion of solar energy into electric energy, and the electric energy into usable hydrogen energy. After the hydrogen production device 4 works for the rated time, the hydrogen production is completed. At this time, the input end of the hydrogenation component is separated from the output end of the hydrogen production device 4, and the transmission platform 1 continues to work to continue to transmit the hydrogen production device 4 that has completed hydrogen production to the outlet of the shell 2, and at the same time, the hydrogen production device 4 to be worked is continued to be transmitted to the working position opposite to the hydrogenation component to continue the next round of hydrogen production.

[0064] Those skilled in the art can understand that the photovoltaic module is a prior art, which mainly includes a photovoltaic panel 301, an electric energy output terminal 302, a controller and a battery. The photovoltaic panel 301 converts solar energy into DC power, and the electric energy output terminal 302 is used to connect to a load, so that the photovoltaic module provides power to the load, and the battery stores the unused DC power.

[0065] Optionally, in an implementation of this embodiment, as Figure 2-4 As shown,

[0066] The hydrogenation assembly includes a first connecting pipe 501 and a second connecting pipe 502 connected to the lower end of the first connecting pipe 501. The first connecting pipe 501 is movably connected to the top wall of the shell 2, and the second connecting pipe 502 is located in the transmission space as the input end of the hydrogenation assembly.

[0067] In this embodiment, the first connecting pipe 501 is movable under the action of external force and works through the transmission platform 1. Shanghai 2024-11484 (M240573CNI)

[0068] The hydrogen production device 4 is transferred to a position opposite to the hydrogenation assembly. Figure 2As shown, the first connecting pipe 501 moves downward, and the second connecting pipe 502 moves downward accordingly, and connects with the output end of the hydrogen production device 4 to form a hydrogenation passage, and the hydrogen production device 4 is started to start hydrogen production. During the hydrogen production process of the hydrogen production device 4, hydrogen is transmitted along the output end of the hydrogen production device 4, the second connecting pipe 502 and the first connecting pipe 501. The upper end of the first connecting pipe 501 is located outside the shell 2, and the input end of the high-pressure storage tank for storing hydrogen is connected to the upper end of the first connecting pipe 501, so as to receive and store hydrogen. After the hydrogen production device 4 works for the rated time, the hydrogen production ends. At this time, as shown in FIG. Figure 3 As shown, the first connecting pipe 501 moves upward, and the second connecting pipe 502 moves upward accordingly, and the second connecting pipe 502 is separated from the output end of the hydrogen production device 4, and the transmission platform 1 continues to work to continue to transmit the hydrogen production device 4 that has completed hydrogen production to the outlet of the shell 2, thereby completing a single round of hydrogen production, and the transmission platform 1 continuously transmits the hydrogen production device 4 to be worked to the working position opposite to the hydrogenation component, and performs multiple rounds of hydrogen production, thereby completing the continuous hydrogen production and hydrogenation process, and the hydrogen production efficiency is improved, while reducing the transportation risk.

[0069] Optionally, in an implementation of this embodiment, as Figure 5 As shown,

[0070] The end of the second connecting pipe 502 away from the output end of the hydrogen production device 4 is the first end, and the end of the second connecting pipe 502 close to the output end of the hydrogen production device 4 is the second end. The diameter of the second connecting pipe 502 gradually increases from the first end to the second end. The diameter of the first connecting pipe 501 is less than or equal to the diameter of the first end of the second connecting pipe 502.

[0071] An elastic bag 503 is provided on the inner wall of the second connecting pipe 502. When the second connecting pipe 502 is connected to the output end of the hydrogen production device 4 to form a hydrogenation passage, the second connecting pipe 502 covers the output end of the hydrogen production device 4 and the elastic bag 503 is squeezed and deformed by the output end of the hydrogen production device 4.

[0072] In this embodiment, the diameter of the second connecting pipe 502 is designed to gradually increase from top to bottom, that is, the port opening area of ​​the second connecting pipe 502 close to the output end of the hydrogen production device 4 is larger, so that the second connecting pipe 502 has a certain fault tolerance when docking with the output end of the hydrogen production device 4, and it is easier to align with the output end of the hydrogen production device 4, thereby enabling the transmission platform 1 to work and transmit the hydrogen production device 4 to the position opposite to the hydrogenation assembly. In the case of inaccurate position, the second connecting pipe 502 can still accurately cover the hydrogen production device 4. Shanghai 2024-11484 (M240573CNI)

[0073] The output end of the hydrogen production device 4, so that when the second connecting pipe 502 moves downward, the output end of the hydrogen production device 4 smoothly enters the first connecting pipe 501 along the second connecting pipe 502, and the output end of the hydrogen production device 4 is sealed and connected with the first connecting pipe 501, so as to output hydrogen;

[0074] The elastic bag 503 can be an inflatable bag structure or an elastic rubber bag. The elastic bag 503 can be deformed under the action of force and restore the deformation when no force is applied. In the process of connecting the second connecting pipe 502 with the output end of the hydrogen production device 4 to form a hydrogenation passage, the second connecting pipe 502 covers the output end of the hydrogen production device 4 and the elastic bag 503 is squeezed and deformed by the output end of the hydrogen production device 4. The setting of the elastic bag 503 further plays a flexible guiding role for the output end of the hydrogen production device 4, so that the output end of the hydrogen production device 4 is extended into the second connecting pipe 502, even if the output end of the hydrogen production device 4 is in the first connecting pipe 501, When the second connecting pipe 502 is not aligned with the output end of the hydrogen production device 4, since the opening area of ​​the pipe mouth of the second connecting pipe 502 close to the output end of the hydrogen production device 4 is larger, the covering area is also relatively large, and the output end of the hydrogen production device 4 can be efficiently covered. As the second connecting pipe 502 and the first connecting pipe 501 gradually move downward, the output end of the hydrogen production device 4 contacts the elastic capsule 503 and squeezes the elastic capsule 503 in a small range. The elastic capsule 503 gives a reaction force to the output end of the hydrogen production device 4, so that it is adjusted to the right position in the second connecting pipe 502 and smoothly enters the first connecting pipe 501 to complete the docking.

[0075] Optionally, in an implementation of this embodiment, as Figure 7 , 8 As shown,

[0076] The output end of the hydrogen production device 4 includes a third connecting pipe 401 and a sealing ring 402 connected to the top of the third connecting pipe 401 . When the second connecting pipe 502 is connected to the output end of the hydrogen production device 4 to form a hydrogenation passage, the sealing ring 402 abuts against the inner wall of the first connecting pipe 501 .

[0077] In this embodiment, the sealing ring 402 protrudes from the third connecting tube 401. During the downward movement of the second connecting tube 502, the output end of the hydrogen production device 4 smoothly enters into the first connecting tube 501 along the second connecting tube 502, that is, the sealing ring 402 abuts against the inner wall of the first connecting tube 501, thereby realizing a sealed connection between the output end of the hydrogen production device 4 and the first connecting tube 501, thereby ensuring safety during the hydrogen output process.

[0078] Optionally, in an implementation of this embodiment, as Figure 6 As shown, Shanghai 2024-11484 (M240573CNI)

[0079] The middle portion of the elastic bag 503 protrudes toward the inside of the second connecting pipe 502 compared to the two ends thereof.

[0080] In the present embodiment, the shape of the elastic bag 503 is designed so that the middle portion protrudes further toward the inside of the second connecting tube 502 than the two ends. The elastic bag 503 of this shape can fully exert the flexible guiding effect on the third connecting tube 401 and the sealing ring 402 at its upper end. During the contact between the sealing ring 402 and the elastic bag, the elastic bag 503 has a tendency to gradually become thicker from the lowest end to the middle position, so that during the process of the sealing ring 402 extending into the second connecting tube 502, the position of the sealing ring 402 gradually aligns with the first connecting tube 501 following the guidance of the elastic bag 503, and finally smoothly enters the first connecting tube 501.

[0081] Optionally, in an implementation of this embodiment, as Figure 2-4 As shown,

[0082] The hydrogenation assembly further includes a first fixed sleeve 504, a second fixed sleeve 505 and a driving unit;

[0083] The first fixing sleeve 504 is fixedly passed through the top wall of the housing 2, and the first connecting pipe 501 is slidably connected in the first fixing sleeve 504;

[0084] The second fixed sleeve 505 is fixedly connected to the outer wall of the first connecting pipe 501 . A rack 507 is provided on the side wall of the second fixed sleeve 505 . The driving part includes a driving motor and a driving gear 508 which is transmission-connected to the output end of the driving motor. The driving gear 508 meshes with the rack 507 .

[0085] In this embodiment, the setting of the first fixed sleeve 504 facilitates the sliding connection of the first connecting pipe 501. By driving the motor, the driving gear 508 is driven to rotate. The rotation of the driving gear 508 drives the rack 507 to move upward or downward. The first connecting pipe 501 moves upward or downward with the rack 507, thereby realizing the connection between the input end of the hydrogenation component and the output end of the hydrogen production device 4.

[0086] Those skilled in the art can understand that the driving motor and the driving gear 508 are supported by a fixing frame, a fixing plate or a fixing rod fixed on the top wall of the housing 2 .

[0087] Optionally, in an implementation of this embodiment, as Figure 7 , 8 As shown,

The second reaction chamber 405 is provided with an anode rod 407, which is located in the second reaction chamber 405 and undergoes an anode reaction with the electrolyte to generate oxygen.

[0091] In this embodiment, the hydrogen production device 4 uses a hydrolysis hydrogen production method to produce hydrogen. Specifically, the diaphragm 408 is a proton exchange membrane, which separates the tank 403 into a first reaction chamber 404 and a second reaction chamber 405. The first reaction chamber 404 is a cathode reaction chamber. The cathode rod 406 reacts with the electrolyte to generate hydrogen. The cathode reaction is: 4H + +4e - →2H 2 The second reaction chamber 405 is an anode reaction chamber, where the anode rod 407 reacts with the electrolyte to generate oxygen. The anode reaction is: 2H 2 O→4H + +4e - +O 2 The hydrogen production device 4 produces hydrogen by electrolyzing water. On the basis of the photovoltaic module providing it with electricity, it forms an integrated hydrogen production and hydrogenation system with the transmission platform 1 and the hydrogenation component, realizing the closed-loop preparation of clean energy, effectively improving the hydrogen production efficiency and reducing the transportation risk.

The main driving gear 5081 and the slave driving gear 5082 rotate in opposite directions, which can respectively drive the rack 507 meshing with it to move in the same direction, thereby realizing that one second connecting pipe 502 is connected to the hydrogen distribution pipe 4011, and the other second connecting pipe 502 is connected to the oxygen distribution pipe, and hydrogen and oxygen can be output at the same time.

[0100] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0101] A limiting member 6 is disposed on the transmission platform 1 , and the hydrogen production device 4 is located at the limiting member 6 and is limited in position by the limiting member 6 .

[0102] In this embodiment, the limiting member 6 is composed of symmetrically arranged arc-shaped limiting protrusions, which are respectively located on both sides of the hydrogen production device 4, so as to limit the position of the hydrogen production device 4 on the transmission platform 1 and prevent the hydrogen production device 4 from shifting.

[0103] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0104] The top wall of the housing 2 includes a first top wall 201 and a second top wall 202 connected to both sides of the first top wall 201;

[0105] The first top wall 201 is arranged straight, the second top wall 202 is arranged inclined relative to the first top wall 201 , a plurality of photovoltaic panels 301 are arranged, and the plurality of photovoltaic panels 301 are arranged on the second top wall 202 at intervals.

[0106] In this embodiment, the top wall of the housing 2 is designed to be straight in the middle and inclined on both sides, which is convenient for the arrangement of the photovoltaic panels 301. The photovoltaic panels 301 are arranged at intervals on the inclined second top wall 202, which is also conducive to Shanghai 2024-11484 (M240573CNI)

[0107] The photovoltaic panel 301 receives sunlight from multiple angles, and the first top wall 201 is arranged flat, which facilitates the connection of the hydrogenation assembly.

[0108] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0109] The photovoltaic assembly also includes an electric energy output terminal 302, which is arranged on the inner wall of the outer shell 2. A plug 7 that is plugged into the electric energy output terminal 302 is arranged on the outer wall of the hydrogen production device 4. When the input end of the hydrogenation assembly is connected to the output end of the hydrogenation device 4 to form a hydrogenation passage, the plug 7 is plugged into the electric energy output terminal 302 to electrically connect the photovoltaic assembly to the hydrogenation device 4.

[0110] In this embodiment, the power output end 302 includes a movable bracket 3021 and a socket 3022 slidably connected to the movable bracket 3021;

[0111] A buffer seat, which is arranged between the movable bracket 3021 and the socket 3022, and a pressure sensor is arranged at the connection between the buffer seat and the socket 3022;

[0112] When the plug 7 is plugged into the power output terminal 302, the pressure sensor is subjected to pressure from the socket 3022 and the buffer seat;

[0113] The distributed off-grid hydrogen production and hydrogenation integrated system also includes a controller, which is designed to: receive a pressure value transmitted by a pressure sensor, and when the pressure value is equal to a preset pressure value, control the transmission platform 1 to stop working.

[0114] Preferably, the buffer seat includes two seat plates 3024 and an elastic member 3023 , wherein one seat plate 3024 is connected to the socket 3022 , and the other seat plate 3024 is connected to the movable bracket 3021 , and both ends of the elastic member 3023 are respectively connected to the two seat plates 3024 .

[0115] Preferably, the elastic member 3023 is a spring.

[0116] Specifically, the controller controls the distributed off-grid hydrogen production and hydrogenation integrated system, controls the transmission platform 1 to work, and transmits the hydrogen production device 4 to a position opposite to the hydrogenation component, that is, the working position of the hydrogen production device 4. For the determination of the working position, a photoelectric switch can be set at a predetermined position. When the hydrogen production device 4 blocks the photoelectric switch, the controller receives a signal fed back by the photoelectric switch, and then controls the transmission platform 1 to stop working and start the corresponding hydrogen production and hydrogenation process; the above-mentioned pressure sensor can also be used, and the plug 7 is the same as Shanghai 2024-11484 (M240573CNI)

[0117] When the power output terminal 302 is plugged in, the pressure sensor is subjected to pressure from the socket 3022 and the buffer seat; when the pressure value is equal to the preset pressure value, the controller receives the feedback signal from the pressure sensor and controls the transmission platform 1 to stop working. At this time, the plug 7 is plugged in to the power output terminal 302, and the hydrogen production device 4 is also in the working position. When the hydrogen production device 4 is also in the working position, the controller controls the hydrogen production device 4 to start and start hydrogen production. The distributed off-grid formed by the photovoltaic assembly provides the hydrogen production device 4 with the electric energy required for its hydrogen production. Thus, the distributed off-grid hydrogen production and hydrogenation integrated system can realize the conversion of solar energy into electric energy, and the electric energy into usable hydrogen energy. After the hydrogen production device 4 works for the rated time, the controller controls the hydrogen production device 4 to stop working, the input end of the hydrogenation assembly is separated from the output end of the hydrogen production device 4, and the transmission platform 1 is controlled to work to drive the hydrogen production device 4 to move in the opposite direction, so that the plug 7 is separated from the electric energy output end 302 and the power is cut off, and the mobile bracket 3021 is controlled to move up to make way for the overall movement of the hydrogen production device 4. When the hydrogen production device 4 moves away as a whole, the mobile bracket 3021 is controlled to reset, and the transmission platform 1 continues to work to continue to transmit the hydrogen production device 4 that has finished hydrogen production to the outlet of the shell 2, and at the same time, the hydrogen production device 4 to be worked is continued to be transmitted to the working position opposite to the hydrogenation assembly to continue the next round of hydrogen production. The moving mode of the mobile bracket 3021 can be driven by an electric control push rod.

[0118] In summary, the ingenious concept of the distributed off-grid hydrogen production and hydrogenation integrated system lies in:

[0119] First, by designing a transmission platform and an outer shell, a transmission space for the hydrogen production device is formed, so that the hydrogen production device can be continuously transmitted to the transmission space opposite to the hydrogenation component, and a hydrogenation passage is formed by connecting the input end of the hydrogenation component with the output end of the hydrogen production device, so that the hydrogen generated in the hydrogen production device is directly transmitted to the outside through the hydrogenation passage. A corresponding high-pressure storage tank for storing hydrogen can be set outside to receive and store hydrogen, thereby forming a distributed off-grid hydrogen production and hydrogenation integrated system, realizing orderly connection between hydrogen production and hydrogenation, effectively improving hydrogen production efficiency, and reducing transportation risks.

[0120] Second, the hydrogen production device is transferred to the opposite side of the hydrogenation component through the transmission platform. At this time, the hydrogenation path is formed by connecting the input end of the hydrogenation component with the output end of the hydrogen production device, and the hydrogen production device is started to produce hydrogen. The distributed off-grid formed by the photovoltaic module becomes the hydrogen production device to provide the electricity required for its hydrogen production. Therefore, the distributed off-grid hydrogenation and hydrogenation integrated system can realize the conversion of solar energy into electrical energy. Shanghai 2024-11484 (M240573CNI)

[0121] The electrical energy is converted into usable hydrogen energy. After the hydrogen production device has worked for the rated time, the hydrogen production is completed. At this time, the input end of the hydrogenation component is separated from the output end of the hydrogen production device, and the transmission platform continues to work to transfer the hydrogen production device that has completed hydrogen production to the outlet of the shell. At the same time, the hydrogen production device to be worked is continued to be transferred to the working position opposite to the hydrogenation component to continue the next round of hydrogen production, forming a closed-loop hydrogen production and hydrogenation cycle.

[0122] Thirdly, the diameter of the second connecting pipe is designed to gradually increase from top to bottom, that is, the port opening area of ​​the second connecting pipe close to the output end of the hydrogen production device is larger, so that the second connecting pipe has a certain fault tolerance when docking with the output end of the hydrogen production device, and it is easier to align with the output end of the hydrogen production device, thereby enabling the transmission platform to work and transmit the hydrogen production device to a position opposite to the hydrogenation component. Even if the position is not accurate, the second connecting pipe can still accurately cover the output end of the hydrogen production device, so that during the downward movement of the second connecting pipe, the output end of the hydrogen production device smoothly enters into the first connecting pipe along the second connecting pipe, and hydrogen is smoothly output.

[0123] Fourth, the setting of the elastic bag further plays a flexible guiding role for the output end of the hydrogen production device, so that when the output end of the hydrogen production device is extended into the second connecting pipe, the output end of the hydrogen production device contacts the elastic bag and squeezes the elastic bag in a small range. The elastic bag gives a reaction force to the output end of the hydrogen production device, so that it can be adjusted to the right position in the second connecting pipe and smoothly enter the first connecting pipe to complete the docking.
