Description

Technical Field

[0001] The present invention belongs to the field of photovoltaic electrocatalysis, and in particular relates to an intelligent control system for photovoltaic wave electrocatalytic hydrogen production and ammonia. Background Art

[0002] With growing demand for photovoltaics, the photovoltaic industry is developing rapidly. However, due to factors such as weather conditions and geographical location, photovoltaic power generation faces intermittent and volatile risks in field applications. Furthermore, while parts of northwest my country are rich in solar energy resources, their capacity to absorb the power is insufficient, with a curtailment rate approaching 20%. Addressing this issue is a critical issue that cannot be ignored in the green and high-quality development of renewable energy.

[0003] To reduce the problem of curtailed solar power, utilizing surplus electricity resources, connecting them to the grid promptly, and consuming them locally has become a solution. Hydrogen, with its high energy density and calorific value, is an important energy storage method. Currently, water electrolysis is becoming the primary technology for hydrogen production, but it faces energy consumption and cost challenges. Utilizing curtailed renewable energy to produce hydrogen can significantly reduce hydrogen production costs. Given the volatility of renewable energy and the difficulty in storing and transporting hydrogen, green synthetic ammonia, a safer and more economical carrier, can be used as a hydrogen storage medium. Therefore, the application and development of green hydrogen and ammonia is a technological path for photovoltaic power consumption, offering a solution that balances low carbon emissions and economic efficiency. Research on direct electrolysis reactions using photovoltaic power generation can address the intermittent nature of photovoltaic power generation and convert electrical energy into high-value chemicals for storage as chemical energy, providing an innovative approach to energy conversion and storage. Although existing technologies have proposed using photovoltaic power generation to produce fuels such as hydrogen and ammonia, existing systems often lack research on photovoltaic module types and mechanisms for monitoring and controlling photovoltaic fluctuations in electrocatalysis, resulting in low energy efficiency and incomplete evaluation and testing of photovoltaic module types. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide an intelligent control system for photovoltaic volatility electrocatalytic hydrogen production and ammonia, which can deploy different types of photovoltaic modules, conduct evaluation tests of different types of photovoltaic module-driven electrolysis reactions, monitor the impact of photovoltaic volatility, and further track the light through the adjustment mechanism, effectively improve the utilization rate of light energy, and carry out photovoltaic power generation-driven electrocatalytic hydrogen production and ammonia reactions.

[0005] The present application provides an intelligent control system for photovoltaic-fluctuating electrocatalytic hydrogen production and ammonia production, comprising a photovoltaic module, a power storage mechanism, an electrocatalytic hydrogen production and ammonia production device, and a regulating mechanism. The photovoltaic module, i.e., a photovoltaic panel, is used to receive light to generate electrical energy. The photovoltaic module can be a type of solar cell module such as TOPCon, HJT, BC, perovskite, or cadmium sulfide. The power storage mechanism is electrically connected to the photovoltaic module and is used to store the electrical energy generated by the photovoltaic module. The electrocatalytic hydrogen production and ammonia production device is electrically connected to both the photovoltaic module and the power storage mechanism. The regulating mechanism includes a mounting base, a rotating assembly, a stop assembly, a first drive member, and a second drive member. A first mounting cavity is provided in the mounting base; a rotating component is rotatably arranged on the mounting base and extends along the direction of gravity, one end of the rotating component is located in the first mounting cavity, and the other end of the rotating component is provided with the photovoltaic component; a stop component is arranged in the first mounting cavity and can move along a first direction, and the stop component abuts against the circumferential side of the rotating component along the first direction to limit the rotation of the rotating component, and the first direction is perpendicular to the direction of gravity; a first driving member is electrically connected to the power storage mechanism and is used to drive the rotating component to rotate; a second driving member is electrically connected to the photovoltaic component and is used to drive the stop component to move along the first direction.

[0006] Specifically, when there is sufficient sunlight in the direction facing the photovoltaic component, the photovoltaic component converts light energy into electrical energy. Part of the electrical energy generated by the photovoltaic component is used to store in the power storage mechanism, and the other part is used for the electrocatalytic hydrogen ammonia device. At the same time, part of the electrical energy is used for the second driving member, so that the second driving member drives the stop component to move along the first direction, so as to drive the stop component to abut against the rotating component, thereby limiting the movement of the rotating component, so that the rotating component drives the photovoltaic component to be located at a light angle and direction that can generate the maximum power point.

[0007] When the direction facing the photovoltaic assembly is not sufficiently sunny, the photovoltaic assembly generates less or no electricity, causing the second drive frame to no longer drive the stop assembly to abut against the rotating assembly in the first direction, thereby enabling the first drive member to drive the rotating assembly to rotate, thereby causing the photovoltaic assembly to rotate, until the direction facing the photovoltaic assembly is sufficiently sunny, so that the electricity generated by the photovoltaic assembly can be used by the second drive member, causing the second drive member to drive the stop assembly to move in the first direction, thereby driving the stop assembly to abut against the rotating assembly, thereby limiting the movement of the rotating assembly. This allows the photovoltaic assembly to face the direction with better sunlight for a longer period of time, allowing the photovoltaic assembly to track sunlight and improve light energy utilization.

[0008] In some embodiments, the rotating assembly includes a spline shaft and a transmission shaft, the photovoltaic assembly is provided at one end of the transmission shaft, the end of the transmission shaft away from the photovoltaic assembly is rotatably provided on the mounting base, and has a spline hole adapted to the spline shaft, and one end of the spline shaft can be movably provided in the spline hole along the direction of gravity; the stop assembly includes a first stop block, and the first stop block is provided with a card groove adapted to the spline shaft on the side facing the spline shaft in the first direction.

[0009] In the above technical solution, the rotation of the rotating assembly is limited by cooperating with the clamping groove and the spline shaft, which is more stable than limiting the rotation of the rotating assembly by friction.

[0010] In some embodiments, the rotating assembly further comprises a first transmission disc and a second transmission disc. The first transmission disc is disposed at the output end of the first driving member and is located in the first mounting cavity, and a groove is provided on the end surface of the first transmission disc facing the spline shaft in the direction of gravity; the second transmission disc is disposed at an end of the spline shaft away from the transmission shaft and is located in the first mounting cavity, and a protrusion corresponding to the groove is provided on the end surface of the second transmission disc facing the first transmission disc in the direction of gravity, and the protrusion is engaged with the groove so that the first transmission disc drives the second transmission disc to move.

[0011] In the above technical solution, the first transmission plate and the second transmission plate are connected by locking the protrusion into the groove, so that the first driving member can drive the rotating assembly to rotate. The structure is simple and easy to implement. At the same time, the first driving member and the rotating assembly are detachably connected, which facilitates installation and removal of the first driving member and the rotating assembly.

[0012] In some embodiments, the stop assembly further includes a mounting seat and a second stop block. The mounting seat is connected to the second driving member, and the first stop block is elastically connected to the mounting seat. The second stop block is disposed on a side of the mounting seat facing the spline shaft along the first direction. The second stop block is provided with a first guide surface. The outer periphery of the spline shaft is provided with a second guide surface adapted to the first guide surface. The first guide surface moves relative to the second guide surface along the first direction to guide the protrusion out of the groove.

[0013] Specifically, when there is sufficient sunlight in the direction facing the photovoltaic assembly, the photovoltaic assembly converts light energy into electrical energy. Part of the electrical energy generated by the photovoltaic assembly is used to store in the power storage mechanism, and the other part is used for the electrocatalytic hydrogen ammonia device. At the same time, part of the electrical energy is used for the second driving member, so that the second driving member drives the stop assembly to move in the first direction, thereby driving the first stop block to abut against the spline shaft to limit the rotation of the spline shaft. Subsequently, the first guide surface of the second stop block abuts against the first guide surface, so that the protrusion disengages from the groove, thereby preventing the first driving member from having a tendency to drive the spline shaft to continue to rotate, resulting in the surface of the spline shaft or the slot being crushed.

[0014] In the above technical solution, the first guide surface moves along the first direction relative to the second guide surface to guide the protrusion to disengage from the groove, so that after the first stop block limits the rotation of the rotating assembly, the second stop block can drive the protrusion to disengage from the groove, so that the first driving member can drive the first transmission disk to move, thereby reducing the risk of damage to the first driving member due to excessive load.

[0015] In some embodiments, the rotating assembly also includes a mounting plate and a first elastic member, the mounting base has a second mounting cavity, the second mounting cavity and the first mounting cavity are arranged along the direction of gravity, the end of the spline shaft away from the second transmission disk passes through the first mounting cavity and the second mounting cavity in sequence, the mounting plate is arranged on the outer periphery of the spline shaft and is located in the second mounting cavity; the first elastic member is sleeved on the outside of the spline shaft and is located in the second mounting cavity, the first elastic member is configured to provide elastic force to the mounting plate to drive the spline shaft to drive the second transmission disk close to the first transmission disk.

[0016] In the above technical solution, the first elastic member can provide an elastic force to the mounting plate, thereby driving the spline shaft to drive the second transmission plate toward the first transmission plate. As a result, after the first guide surface no longer abuts the second guide surface, the first elastic member can drive the protrusion on the second transmission plate to re-engage within the groove of the first transmission plate, thereby facilitating the first driving member to drive the rotating assembly and the photovoltaic assembly to rotate. This provides greater stability than a situation where the protrusion on the second transmission plate is re-engaged within the groove of the first transmission plate due to the deadweight of the spline shaft.

[0017] In some embodiments, the second transmission disk has a first end face facing the first transmission disk, the first end face is recessed to form a receiving groove, and the protrusion is arranged on the bottom wall of the receiving groove; the first mounting cavity has a first inner surface facing the first end face in the direction of gravity, and the first driving member is provided with a pressure-sensitive switch on the first inner surface, and the first end face moves close to the first inner surface to trigger the pressure-sensitive switch.

[0018] Specifically, when there is sufficient sunlight in the direction facing the photovoltaic component, the second driving member drives the stop assembly to move in the first direction, so as to drive the first stop block to abut against the spline shaft to limit the rotation of the spline shaft. Then the first guide surface of the second stop block abuts against the first guide surface, so that the protrusion disengages from the groove, and the first end face no longer triggers the pressure-sensitive switch, thereby causing the first driving member to stop rotating, thereby reducing power waste.

[0019] When there is insufficient light in the direction facing the photovoltaic component, the second transmission disk moves toward the first transmission disk under the action of the first elastic member or its own gravity, so that the protrusion engages with the groove, and then the first end face triggers the pressure-sensitive switch, so that the first drive member continues to drive the spline shaft to continue rotating.

[0020] In some embodiments, the inner surface is recessed to form a mounting groove, and the pressure-sensitive switch is arranged on the bottom wall of the mounting groove; the adjustment mechanism also includes a second elastic member, one end of the second elastic member is connected to the pressure-sensitive switch, and the other end of the second elastic member is located outside the mounting groove.

[0021] In the above technical solution, a second elastic member is provided so that when the protrusion and the groove are misaligned, causing the protrusion to abut against the end face of the first transmission disk provided with the groove, the first end face can still trigger the pressure-sensitive switch so that the first driving member drives the first rotating disk to idle until the groove and the protrusion are engaged.

[0022] In some embodiments, a third mounting cavity is defined within the mounting base, the first mounting cavity and the third mounting cavity are arranged along the direction of gravity, and the first driving member and the power storage mechanism are disposed in the third mounting cavity.

[0023] In the above technical solution, the first driving member and the power storage mechanism are arranged in the third mounting cavity. This not only provides a stable working space for the first driving member and the power storage mechanism, improving their stability, but also facilitates electrical connection between the first driving member and the power storage mechanism, thus reducing the manufacturing difficulty of the mechanism.

[0024] In some embodiments, the electrocatalytic hydrogen production ammonia device includes an electrolytic cell, a feed mechanism, and a gas-liquid separator. The electrolytic cell is provided with an electrode end plate, a gasket, a flow field network, an ion exchange membrane, and a self-supporting catalyst. The electrolytic cell is electrically connected to the photovoltaic module and the power storage mechanism via the electrode end plate. The feed mechanism is connected to the feed port of the electrolytic cell and is used to provide circulating water, a nitrogen source, or carbon dioxide into the electrolytic cell to generate hydrogen (H2), (NH3), or methanol (CH3OH) through the electrolysis reaction. The gas-liquid separator is connected to the discharge port of the electrolytic cell and is used to separate the reactants.

[0025] In some embodiments, the electrocatalytic hydrogen production system further includes a step-up transformer and a controller. The photovoltaic module and the power storage mechanism are electrically connected to the electrodes via the step-up transformer, which is configured to regulate the output voltages of the photovoltaic module and the power storage mechanism. The controller is electrically connected to the step-up transformer. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] With growing demand for photovoltaics, the photovoltaic industry is developing rapidly. However, due to factors such as weather conditions and geographical location, photovoltaic power generation faces intermittent and volatile risks in field applications. Furthermore, while parts of northwest my country are rich in solar energy resources, their capacity to absorb the power is insufficient, with a curtailment rate approaching 20%. Addressing this issue is a critical issue that cannot be ignored in the green and high-quality development of renewable energy.

[0033] To reduce the problem of curtailed solar power, utilizing surplus electricity resources, connecting them to the grid promptly, and consuming them locally has become a solution. Hydrogen, with its high energy density and calorific value, is an important energy storage method. Currently, water electrolysis is becoming the primary technology for hydrogen production, but it faces energy consumption and cost challenges. Utilizing curtailed renewable energy to produce hydrogen can significantly reduce hydrogen production costs. Given the volatility of renewable energy and the difficulty in storing and transporting hydrogen, green synthetic ammonia, a safer and more economical carrier, can be used as a hydrogen storage medium. Therefore, the application and development of green hydrogen and ammonia is a technological path for photovoltaic power consumption, offering a solution that balances low carbon emissions and economic efficiency. Research on direct water electrolysis to produce hydrogen using photovoltaic power can address the intermittent nature of photovoltaic power generation and convert electrical energy into chemical energy for storage, providing a new approach for energy conversion and storage. Furthermore, electrocatalytic nitric acid reduction to synthesize ammonia offers an effective, more energy-efficient and environmentally friendly approach to expanding the application of photovoltaics in electrocatalysis and hydrogen transportation. Although existing technologies have proposed using photovoltaic power to produce fuels such as hydrogen and ammonia, existing systems often lack mechanisms to track sunlight, resulting in low energy efficiency.

[0034] In order to solve the above technical problems, refer to Figures 1-8 The present invention provides an intelligent control system for photovoltaic-based electrocatalytic hydrogen production and ammonia production. The electrocatalytic hydrogen production and ammonia production system includes a photovoltaic module 10, a power storage mechanism 20, an electrocatalytic hydrogen production and ammonia production device 30, and a regulating mechanism 60. The photovoltaic module 10 is configured to receive light to generate electrical energy; the power storage mechanism 20 is electrically connected to the photovoltaic module 10 and is configured to store the electrical energy generated by the photovoltaic module 10; the electrocatalytic hydrogen production and ammonia production device 30 is electrically connected to both the photovoltaic module 10 and the power storage mechanism 20; and the regulating mechanism 60 includes a mounting base 61, a rotating assembly 62, a stop assembly 63, a first driving member 64, and a second driving member 66. The mounting base 61 has a first mounting cavity 61A therein; the rotating assembly 62 is rotatably disposed on the mounting base 61 and extends along the gravity direction Y, one end of the rotating assembly 62 is located in the first mounting cavity 61A, and the other end of the rotating assembly 62 is provided with a photovoltaic assembly 10; the stop assembly 63 is disposed in the first mounting cavity 61A and can move along the first direction X, and the stop assembly 63 abuts against the circumferential side of the rotating assembly 62 along the first direction X to limit the rotation of the rotating assembly 62, where the first direction X is perpendicular to the gravity direction Y; the first driving member 64 is electrically connected to the power storage mechanism 20 and is used to drive the rotating assembly 62 to rotate; the second driving member 66 is electrically connected to the photovoltaic assembly 10 and is used to drive the stop assembly 63 to move along the first direction X.

[0035] The photovoltaic module 10 can directly convert sunlight energy into direct current through the photoelectric effect, and its core component is a solar cell made of semiconductor materials (such as silicon).

[0036] Exemplarily, the photovoltaic module 10 is a solar cell module such as TOPCon, HJT, BC, perovskite, or cadmium sulfide.

[0037] The power storage mechanism 20 may be a battery.

[0038] The first driving member 64 may be a servo motor, which drives the rotating assembly 62 to rotate via a coupling.

[0039] The second driving member 66 can be an electromagnetic cylinder or electromagnetic push-pull rod, etc., which is generally composed of a cylinder body, an electromagnet, an elastic member, and an iron core. When powered, the solenoid valve or built-in electromagnet generates a magnetic field to drive the iron core, causing it to move and stretch the elastic member. When powered off, the elastic member returns to its original position, causing the iron core to return to its original position.

[0040] The second driving member 66 may be disposed in the first mounting cavity 61A or outside the mounting base.

[0041] It is understandable that the current generated by the photovoltaic assembly 10 should be regulated by the power controller 5041 before being used for the power storage mechanism 20 , the electrocatalytic hydrogen-ammonia device 30 and the second driving member 66 .

[0042] Specifically, when there is sufficient sunlight in the direction facing the photovoltaic component 10, the photovoltaic component 10 converts light energy into electrical energy. Part of the electrical energy generated by the photovoltaic component 10 is used to be stored in the power storage mechanism 20, and the other part is used for the electrocatalytic hydrogen production device 30. At the same time, part of the electrical energy is used for the second driving member 66, so that the second driving member 66 drives the stop component 63 to move along the first direction X, so as to drive the stop component 63 to abut against the rotating component 62, thereby limiting the movement of the rotating component 62, so that the rotating component 62 drives the photovoltaic component 10 to be located in a lighting environment that can enable the photovoltaic component 10 to generate relatively stable electrical energy.

[0043] When the direction facing the photovoltaic assembly 10 is not sufficiently sunny, the amount of electricity generated by the photovoltaic assembly 10 is low or no electricity is generated, so that the second drive frame no longer drives the stop assembly 63 to abut against the rotating assembly 62 in the first direction X, thereby enabling the first drive member 64 to drive the rotating assembly 62 to rotate, thereby causing the photovoltaic assembly 10 to rotate until the direction facing the photovoltaic assembly 10 is sufficiently sunny, so that the electricity generated by the photovoltaic assembly 10 can be used by the second drive member 66, so that the second drive member 66 drives the stop assembly 63 to move in the first direction X, thereby driving the stop assembly 63 to abut against the rotating assembly 62, thereby limiting the movement of the rotating assembly 62. In this way, the photovoltaic assembly 10 can be oriented towards the direction with better sunlight for a longer period of time, so that the photovoltaic assembly 10 can track the sunlight and improve the utilization rate of light energy.

[0044] According to some embodiments of the present application, the rotating assembly 62 includes a spline shaft 621 and a transmission shaft 622, and the photovoltaic assembly 10 is provided at one end of the transmission shaft 622. The end of the transmission shaft 622 away from the photovoltaic assembly 10 is rotatably provided on the mounting base 61 and has a spline hole 6221 adapted to the spline shaft 621. One end of the spline shaft 621 can be movably provided in the spline hole 6221 along the gravity direction Y; the stop assembly 63 includes a first stop block 631, and the first stop block 631 is provided with a card slot 631A adapted to the spline shaft 621 on the side facing the spline shaft 621 in the first direction X.

[0045] In this technical solution, the locking groove 631A cooperates with the spline shaft 621 to limit the rotation of the rotating component 62, which is more stable than limiting the rotation of the rotating component 62 by friction.

[0046] According to some embodiments of the present application, the rotating assembly 62 further includes a first transmission disc 623 and a second transmission disc 624. The first transmission disc 623 is disposed at the output end of the first driving member 64 and is located within the first mounting cavity 61A. A groove 6231 is provided on the end surface of the first transmission disc 623 facing the spline shaft 621 in the direction of gravity Y. The second transmission disc 624 is disposed at the end of the spline shaft 621 away from the transmission shaft 622 and is located within the first mounting cavity 61A. A protrusion 6241 corresponding to the groove 6231 is provided on the end surface of the second transmission disc 624 facing the first transmission disc 623 in the direction of gravity Y. The protrusion 6241 is engaged with the groove 6231, so that the first transmission disc 623 drives the second transmission disc 624 to move.

[0047] In this technical solution, the first transmission plate 623 and the second transmission plate 624 are connected by locking the protrusion 6241 into the groove 6231, so that the first driving member 64 can drive the rotating assembly 62 to rotate. This simple structure is easy to implement. At the same time, the first driving member 64 and the rotating assembly 62 are detachably connected, facilitating installation and removal of the first driving member 64 and the rotating assembly 62.

[0048] According to some embodiments of the present application, the stop assembly 63 further includes a mounting seat 632 and a second stop block 633. The mounting seat 632 is connected to the second driving member 66, and the first stop block 631 is elastically connected to the mounting seat 632. The second stop block 633 is disposed on a side of the mounting seat 632 that faces the spline shaft 621 along the first direction X. The second stop block 633 is provided with a first guide surface 6331. The outer periphery of the spline shaft 621 is provided with a second guide surface 6211 that matches the first guide surface 6331. The first guide surface 6331 moves relative to the second guide surface 6211 along the first direction X to guide the protrusion 6241 out of the groove 6231.

[0049] In some embodiments, the stop assembly 63 further includes a guide rod 6311 and a third elastic member 6312. One end of the guide rod 6311 is connected to the first stop block 631. The mounting base 632 is provided with a guide hole corresponding to the guide rod 6311. The other end of the guide rod 6311 extends along the first direction X and is inserted into the guide hole. The third elastic member 6312 is sleeved over the guide rod 6311. The ends of the third elastic member 6312 are respectively connected to the first stop block 631 and the mounting base 632. For example, the third elastic member 6312 may be a compression spring.

[0050] Specifically, when there is sufficient sunlight in the direction facing the photovoltaic assembly 10, the photovoltaic assembly 10 converts light energy into electrical energy. Part of the electrical energy generated by the photovoltaic assembly 10 is stored in the power storage mechanism 20, and another part is used for the electrocatalytic hydrogen ammonia production device 30. At the same time, part of the electrical energy is used by the second driving member 66, so that the second driving member 66 drives the stop assembly 63 to move along the first direction X, thereby driving the first stop block 631 to abut against the spline shaft 621 to limit the rotation of the spline shaft 621. Subsequently, the first guide surface 6331 of the second stop block 633 abuts the first guide surface 6331, so that the protrusion 6241 disengages from the groove 6231, thereby preventing the first driving member 64 from driving the spline shaft 621 to continue to rotate. This causes the surface of the spline shaft 621 or the slot 631A to be crushed.

[0051] In the present technical solution, the first guide surface 6331 moves along the first direction X relative to the second guide surface 6211 to guide the protrusion 6241 to disengage from the groove 6231, so that after the first stop block 631 limits the rotation of the rotating assembly 62, the second stop block 633 can drive the protrusion 6241 to disengage from the groove 6231, so that the first driving member 64 can drive the first transmission disk 623 to move, thereby reducing the risk of damage to the first driving member 64 due to excessive load.

[0052] According to some embodiments of the present application, the rotating assembly 62 also includes a mounting plate 625 and a first elastic member 626. The mounting base 61 has a second mounting cavity 61B. The second mounting cavity 61B and the first mounting cavity 61A are arranged along the gravity direction Y. The end of the spline shaft 621 away from the second transmission disk 624 passes through the first mounting cavity 61A and the second mounting cavity 61B in sequence. The mounting plate 625 is arranged on the outer periphery of the spline shaft 621 and is located in the second mounting cavity 61B; the first elastic member 626 is sleeved on the outside of the spline shaft 621 and is located in the second mounting cavity 61B. The first elastic member 626 is configured to provide elastic force to the mounting plate 625 to drive the spline shaft 621 to drive the second transmission disk 624 to approach the first transmission disk 623.

[0053] Exemplarily, the first elastic member 626 may be a compression spring.

[0054] In this technical solution, the first elastic member 626 can provide an elastic force to the mounting plate 625, thereby driving the spline shaft 621 to drive the second transmission plate 624 toward the first transmission plate 623. As a result, after the first guide surface 6331 is no longer in contact with the second guide surface 6211, the first elastic member 626 can drive the protrusion 6241 on the second transmission plate 624 to be re-engaged in the groove 6231 of the first transmission plate 623, thereby facilitating the first driving member 64 to drive the rotating assembly 62 and the photovoltaic assembly 10 to rotate. This provides greater stability than a situation where the protrusion 6241 on the second transmission plate 624 is re-engaged in the groove 6231 of the first transmission plate 623 due to the deadweight of the spline shaft 621.

[0055] According to some embodiments of the present application, the second transmission disk 624 has a first end face facing the first transmission disk 623, the first end face is recessed to form a receiving groove 6242, and the protrusion 6241 is arranged on the bottom wall of the receiving groove 6242; the first mounting cavity 61A has a first inner surface facing the first end face in the gravity direction Y, and the first driving member 64 is provided with a pressure-sensitive switch on the first inner surface, and the first end face moves close to the first inner surface to trigger the pressure-sensitive switch.

[0056] Specifically, when there is sufficient light in the direction facing the photovoltaic component 10, the second driving member 66 drives the stop assembly 63 to move along the first direction X, so as to drive the first stop block 631 to abut against the spline shaft 621 to limit the rotation of the spline shaft 621, and then the first guide surface 6331 of the second stop block 633 abuts against the first guide surface 6331, so that the protrusion 6241 disengages from the groove 6231, and the first end face no longer triggers the pressure-sensitive switch, so that the first driving member 64 no longer rotates, thereby reducing power waste.

[0057] When there is insufficient light in the direction facing the photovoltaic component 10, the second transmission disk 624 moves toward the first transmission disk 623 under the action of the first elastic member 626 or its own gravity, so that the protrusion 6241 is engaged with the groove 6231, and then the first end face triggers the pressure-sensitive switch, so that the first driving member 64 continues to drive the spline shaft 621 to continue rotating.

[0058] According to some embodiments of the present application, the inner surface is recessed to form a mounting groove 61D, and the pressure-sensitive switch is arranged on the bottom wall of the mounting groove 61D; the adjustment mechanism 60 also includes a second elastic member 65, one end of the second elastic member 65 is connected to the pressure-sensitive switch, and the other end of the second elastic member 65 is located outside the mounting groove 61D.

[0059] Exemplarily, the second elastic member 65 may be a compression spring.

[0060] In the present technical solution, a second elastic member 65 is provided so that when the protrusion 6241 and the groove 6231 are misaligned, causing the protrusion 6241 to abut against the end face of the first transmission disk 623 provided with the groove 6231, the first end face can still trigger the pressure-sensitive switch so that the first driving member 64 drives the first rotating disk to idle until the groove 6231 is engaged with the protrusion 6241.

[0061] According to some embodiments of the present application, a third mounting cavity 61C is provided in the mounting base 61 , the first mounting cavity 61A and the third mounting cavity 61C are arranged along the gravity direction Y, and the first driving member 64 and the power storage mechanism 20 are arranged in the third mounting cavity 61C.

[0062] In this technical solution, the first driving member 64 and the power storage mechanism 20 are disposed within the third mounting cavity 61C. This provides a stable working space for the first driving member 64 and the power storage mechanism 20, improving their stability. Furthermore, it facilitates electrical connection between the first driving member 64 and the power storage mechanism 20, thus reducing the manufacturing difficulty of the mechanism.

[0063] According to some embodiments of the present application, an electrocatalytic hydrogen-to-ammonia device 30 includes an electrolytic cell 31, a feed mechanism 32, and a gas-liquid separator 33. Electrodes 311 are provided in the electrolytic cell 31, and are electrically connected to the photovoltaic module 10 and the power storage mechanism 20. The feed mechanism 32 is connected to the feed port of the electrolytic cell 31 and is used to provide a nitrogen source and water into the electrolytic cell 31. The gas-liquid separator 33 is connected to the discharge port of the electrolytic cell 31 and is used to separate the reactants.

[0064] The feeding mechanism 32 may include a water circulation box, and the gas-liquid separator 33 may include a gas-liquid separator and a drying pipe.

[0065] The feeding mechanism 32 is used to provide circulating water, nitrogen source or carbon source into the electrolytic cell to generate hydrogen (H2), ammonia (NH3) or methanol (CH3OH) through electrolysis reaction.

[0066] In some embodiments, the electrolyzer 31 comprises five chambers and utilizes proton exchange membrane water electrolysis technology, preferably at an experimental temperature of 65°C or 80°C. The anode catalyst is preferably iridium / iridium oxide (Ir / IrO2), and the cathode catalyst is preferably platinum carbon (Pt / C). The cathode and anode catalysts are coated on both sides of a Nafion 117 membrane, forming CCM electrodes 311. A water circulation tank circulates the electrolyte in the feed mechanism 32. Under photovoltaic power, the electrolyzer 31 electrolyzes the circulating water, producing hydrogen (H2) and oxygen (O2) at the cathode and anode, respectively. The gases are dried and collected in a gas-liquid separator. The collected gas can be tested for purity using a gas chromatograph. Hydrogen products that meet the standards can be directly supplied to end users.

[0067] In some embodiments, electrolytic cell 31 is an anion exchange membrane electrolytic cell 31. Its main components include electrode end plates, a flow field mesh, a gasket, an ion exchange membrane, and a self-supporting catalyst. The flow field plates have either serpentine or parallel channels. The electrolyte is a 30% potassium hydroxide (KOH) solution or a sodium hydroxide (NaOH) solution. The reaction solution is a 0.1–1.0 mol / L solution of potassium nitrate (KNO3), sodium nitrate (NaNO3), potassium nitrite (KNO2), or sodium nitrite (NaNO2).

[0068] In some embodiments, electrolyzer 31 is a proton exchange membrane electrolyzer. Its main components include electrode end plates, a flow field mesh, gaskets, an ion exchange membrane, and a self-supporting catalyst. The flow field plates have either serpentine or parallel channels. The electrolyte is either a 0.5-3.0 mol / L potassium bicarbonate (KHCO₃) solution or a sodium bicarbonate (NaHCO₃) solution, used for the reduction of carbon dioxide to produce methanol (CH₃OH).

[0069] According to some embodiments of the present application, the electrocatalytic hydrogen production system further includes a boost transformer mechanism 40 and a controller 50. The photovoltaic module 10 and the power storage mechanism 20 are electrically connected to the electrode 311 via the boost transformer mechanism 40. The boost transformer mechanism 40 is used to regulate the output voltage and current of the photovoltaic module 10 and the power storage mechanism 20. The controller 50 is electrically connected to the boost transformer mechanism 40.

[0070] In some embodiments, the boost transformer mechanism 40 includes a power controller 5041 and a current converter 42. The power controller 5041 monitors and regulates power parameters (such as voltage, current, and frequency) to ensure equipment operation within a safe range and optimize energy efficiency. Its core functions include overload protection, power factor correction, and harmonic filtering. The current converter 42 can be a DC-DC converter, which uses a switching device (such as a MOSFET) to rapidly switch on and off, chopping the input DC voltage into a pulse sequence. This pulse sequence is then filtered to produce a stable output voltage. Its core functions are voltage step-up and step-down, voltage stabilization, and isolation.

[0071] As will be appreciated, the controller 50 can be electrically connected to the step-up transformer mechanism 40 to distribute the power generated by the photovoltaic module 10, the current and voltage at the input end, and the current and voltage at the output end. When there is sufficient sunlight, the power generated by the photovoltaic module 10 is first supplied to the load end to produce the required products. The remaining power consumed is input into the power storage mechanism 20 for storage and is used when sunlight is insufficient. Furthermore, the controller 50 can periodically de-energize the first driver 64 when the first driver 64 continues to operate and the current and voltage at the input end, or the current and voltage at the output end, do not change significantly. This prevents the first driver 64 from consuming excessive power during rainy weather or at night.

[0072] In some embodiments, the photovoltaic fluctuation electrocatalytic hydrogen production ammonia intelligent control system can be further connected to a communication interface for monitoring and controlling the system, integrating the operating parameters of the system and using a PLC system for real-time monitoring.

[0073] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

Those skilled in the art will appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application are intended to be within the scope of protection of this application.
