[0029] In the related art, it is difficult for hydrogen production equipment to interrupt the chemical reaction in the reactor in time when the gas pressure in the gas tank reaches the set value. This results in the materials in the reactor continuing to react even if the gas tank is full, resulting in waste of resources and unnecessary energy consumption. Since the reaction in the reactor cannot be interrupted in time, the excess hydrogen production agent and reactant continue to react, and the generated hydrogen cannot be effectively stored, resulting in waste of resources. This not only increases production costs, but also reduces the economy and environmental protection of the equipment.

[0030] In the present disclosure, when the internal pressure of the hydrogen storage unit 100 reaches a set value, the driving mechanism 400 can respond quickly, drive the feeding assembly 500 to leave the reaction area, and interrupt the chemical reaction in the reactor in time to avoid waste of resources.

[0031] In one embodiment of the present disclosure, a hydrogen production device is provided, wherein Figure 1 , Figure 2 as well as Figure 3 In the example, the hydrogen production device includes: a hydrogen storage unit 100, a hydrogen production unit 200, a first connecting pipe 300 and a driving mechanism 400. Figure 3 For the attachment Figure 2 Section view along the midline AA.

[0032] exist Figure 2 In the example, the hydrogen storage unit 100 is provided with a hydrogen storage chamber and a pressure monitor 101 for monitoring the pressure of the hydrogen storage chamber. Specifically, the hydrogen storage chamber is used to store the generated hydrogen. The capacity of the hydrogen storage chamber can be designed according to actual needs to meet the hydrogen storage needs in different application scenarios. Optionally, if the pressure in the hydrogen storage unit 100 is too high, it may cause the hydrogen storage chamber to rupture or leak, causing serious safety accidents. The pressure monitor 101 can monitor the pressure in the hydrogen storage chamber in real time. When the pressure exceeds the safety range, an alarm can be issued in time or safety measures can be triggered, such as closing the hydrogen valve 301 and stopping the continued input of hydrogen to ensure the safe operation of the equipment. Through the pressure monitor 101, when the internal pressure of the hydrogen storage unit 100 reaches a critical value, the overpressure protection device (such as a safety valve) can be automatically started to release excess pressure and prevent the hydrogen storage unit 100 from being damaged. In some embodiments, the pressure monitor 101 can record the historical data of pressure changes in the hydrogen storage unit 100, which is convenient for subsequent data analysis and fault diagnosis. These data can help operators and maintenance personnel understand the operating status of the equipment, discover potential problems in time and perform maintenance. exist Figure 1 In the example, the hydrogen storage unit 100 is in a can shape. In other embodiments, the hydrogen storage unit 100 may also be implemented in other shapes according to actual conditions.

[0033] exist Figure 2 In the example, the hydrogen production unit 200 is provided with a hydrogen production chamber for performing a chemical reaction to generate hydrogen. The internal structure design of the hydrogen production chamber should ensure that the reactants and the hydrogen production agent can be fully mixed and reacted to improve the efficiency of hydrogen generation. The shape of the hydrogen production chamber can be Figure 1 The cylindrical shape in the embodiment or the cubic shape or other suitable geometric shapes in other embodiments can adapt to different reaction conditions and process requirements. The material of the hydrogen production chamber should be selected from corrosion-resistant and high-temperature resistant materials, such as stainless steel, titanium alloy or special plastics, to ensure long-term stable operation. These materials can resist the corrosion caused by chemical reactions and the influence of high-temperature environments. A reaction area is provided in the hydrogen production chamber for placing reactants that react with the hydrogen production agent. The design of the reaction area should take into account the distribution and contact area of ​​the reactants to ensure the uniformity and efficiency of the reaction.

[0034] Optional, in Figure 2 In the example, a connecting seat 110 is also fixedly installed between the hydrogen storage unit 100 and the hydrogen production unit 200 to strengthen the connection between the hydrogen storage unit 100 and the hydrogen production unit 200 and prevent the first connecting pipe 300 from breaking due to the separation between the hydrogen storage unit 100 and the hydrogen production unit 200.

[0035] exist Figure 1 In the embodiment, the first connecting pipe 300 connects the hydrogen storage unit 100 and the hydrogen production unit 200, that is, connects the hydrogen storage chamber and the hydrogen production chamber. The hydrogen generated by the hydrogen production unit 200 can flow into the hydrogen storage unit 100 through the first connecting pipe 300. The material of the first connecting pipe 300 can be selected to be corrosion-resistant and high-pressure resistant to ensure the safe transmission of hydrogen. A hydrogen valve 301 is provided on the first connecting pipe 300 to control the flow of hydrogen. The hydrogen valve 301 can adopt an electric or pneumatic valve that can be controlled to be on / off. The response speed of the hydrogen valve 301 can be relatively fast to ensure that it can be quickly closed or opened when needed. Optionally, a flow regulating valve 302 is also provided on the first connecting pipe 300, and the flow regulating valve 302 can adjust the flow of hydrogen in the first connecting pipe 300 to ensure the stability and safety of hydrogen transmission; exist Figure 3 In the embodiment, the driving mechanism 400 is connected to a feeding assembly 500 disposed in the hydrogen storage unit 100, and can drive the feeding assembly 500 to move close to or away from the reaction area in the hydrogen production unit 200. The feeding assembly 500 is used to place the hydrogen production agent, and the reaction area is an area for placing a reactant that reacts with the hydrogen production agent.

[0036] The driving mechanism 400 is configured to drive the feeding assembly 500 to separate from the reaction area in response to a stop signal when the internal pressure of the hydrogen storage unit 100 reaches a set value indicating fullness; and the hydrogen valve 301 is configured to block the first connecting pipe 300 in response to the stop signal.

[0037] As an example, the hydrogen production device may include a control unit (not shown), which is electrically connected to the pressure monitor 101, the drive mechanism 400 and the hydrogen valve 301, and the control unit generates and sends the stop signal in response to the pressure of the hydrogen storage chamber reaching the set value. Alternatively, in other embodiments, the pressure monitor 101 is communicatively connected to the drive mechanism 400, and the pressure monitor 101 has the ability to determine that the internal pressure of the hydrogen storage unit 100 reaches the set value indicating fullness, so that the stop signal is generated by the pressure monitor 101 and sent to the drive mechanism.

[0038] As an example, when the pressure monitor 101 in the hydrogen storage unit 100 detects that the pressure in the hydrogen storage chamber reaches a set value (that is, the hydrogen storage chamber is full or nearly full), the control unit will send a stop signal. After receiving the stop signal, the drive mechanism 400 drives the feeding assembly 500 to disengage from the reaction area and stop supplying the hydrogen production agent to the hydrogen production unit 200. At the same time, the hydrogen valve 301 will also respond to the stop signal, close the first connecting pipe 300, and block the flow of hydrogen from the hydrogen production unit 200 to the hydrogen storage unit 100 to ensure the safe operation of the system. Therefore, the hydrogen production device can interrupt the chemical reaction in time, avoid waste of resources, and improve resource utilization. At the same time, the real-time pressure monitoring and control unit ensures that the internal pressure of the hydrogen storage unit 100 is not too high, thereby improving the safety and reliability of the equipment. In addition, automated control reduces manual intervention and improves the operating efficiency and overall performance of the equipment.

[0039] In some embodiments, the feeding assembly 500 can be designed as a push rod with a container, and the container is used to place the hydrogen-producing agent. The length of the push rod can be designed according to the size of the reaction area of ​​the hydrogen production unit 200 to ensure that the feeding assembly 500 can smoothly enter and exit the reaction area. The material of the feeding assembly 500 should be selected from corrosion-resistant and high-temperature resistant materials, such as stainless steel or special plastics, to ensure long-term stable operation. Optionally, the feeding assembly 500 is a mesh structure, for example, it can be implemented as a mesh basket made of metal wire or corrosion-resistant material. The design of the mesh structure enables the hydrogen-producing agent to be evenly distributed in the mesh basket, increases the contact area with the reactant, and improves the reaction efficiency. The material of the mesh structure should be selected from corrosion-resistant and high-temperature resistant materials, such as stainless steel or special plastics, to ensure long-term stable operation. It can resist the corrosion caused by chemical reactions and the influence of high temperature environments. The size of the mesh structure should be designed according to the size of the reaction area of ​​the hydrogen production unit 200 to ensure that the feeding assembly 500 can smoothly enter and exit the reaction area. The size of the mesh should be moderate to ensure uniform distribution of the hydrogen generating agent without causing leakage of the hydrogen generating agent.

[0040] Optional, in Figure 2 In the example, the hydrogen production device includes: a gas monitor 201, connected to the hydrogen production chamber, for generating a hydrogen production signal when monitoring the hydrogen generated by the hydrogen production unit 200; The hydrogen valve 301 is configured to open the first connecting pipe 300 in response to the hydrogen generation signal.

[0041] Specifically, the gas monitor 201 can use a hydrogen sensor, which has the characteristics of high sensitivity and rapid response, to ensure that the generation of hydrogen can be detected in time. In some embodiments, the gas monitor 201 can be installed at the outlet of the hydrogen production chamber to ensure the accuracy of the detection. The installation location should be selected in a place that will not be interfered by other gases to ensure the accuracy of the test results. When the gas monitor 201 detects hydrogen, the control unit will receive a hydrogen generation signal and immediately control the hydrogen valve 301 to open, so that the generated hydrogen can flow into the hydrogen storage unit 100 through the first connecting pipe 300.

[0042] Optional, in Figure 3 In the example, the driving mechanism 400 includes: a housing 401 and a driving member 402 .

[0043] a housing 401; A driving member 402 is disposed in the housing 401, the telescopic end of the driving member 402 is connected to one end of a telescopic rod 403, and the other end of the telescopic rod 403 is connected to the feeding assembly 500; the driving member 402 drives the telescopic rod 403 to perform telescopic movement to approach or move away from the reaction area.

[0044] Specifically, the housing 401 is used to protect the internal drive member 402 and other components to prevent the influence of the external environment. In some embodiments, the housing 401 can be designed as a cuboid or a cylinder, which is selected according to the type and size of the drive member 402. The internal space of the housing 401 should be sufficient to accommodate the drive member 402 and other components, and the material of the housing 401 should be corrosion-resistant and high-temperature resistant materials, such as stainless steel or special plastics. The drive member 402 can be an electric push rod, a cylinder or a hydraulic cylinder, etc., which can be electrically connected to the control unit, and the telescopic movement of the telescopic rod 403 can be accurately controlled by the control unit. The electric push rod drives the screw or gear mechanism through the motor to make the telescopic rod 403 move linearly. The cylinder drives the piston through compressed air to make the telescopic rod 403 move linearly. The hydraulic cylinder drives the piston through hydraulic oil to make the telescopic rod 403 move linearly. The length and diameter of the telescopic rod 403 should be designed according to the size of the reaction area of ​​the hydrogen production unit 200 to ensure that the feeding assembly 500 can smoothly enter and exit the reaction area.

[0045] When the reaction needs to be started, the control unit sends a command to the driving member 402, and the driving member 402 pushes the telescopic rod 403 to extend, pushes the feeding assembly 500 into the reaction area of ​​the hydrogen production unit 200, makes the hydrogen production agent contact with the reactant, and starts a chemical reaction to generate hydrogen. The gas monitor 201 monitors the gas composition in the hydrogen production chamber in real time. When hydrogen is detected, it generates a hydrogen signal and transmits the signal to the control unit to control the hydrogen valve 301 to open, so that the generated hydrogen can flow into the hydrogen storage chamber of the hydrogen storage unit 100 through the first connecting pipe 300.

[0046] When the internal pressure of the hydrogen storage unit 100 reaches the set value, the control unit will send a stop signal. After receiving the stop signal, the driving member 402 drives the telescopic rod 403 to retract, pulls the feeding assembly 500 out of the reaction area, and stops supplying the hydrogen production agent to the hydrogen production unit 200. At the same time, the hydrogen valve 301 will also respond to the stop signal, close the first connecting pipe 300, and block the flow of hydrogen from the hydrogen production unit 200 to the hydrogen storage unit 100, ensuring the safe operation of the system.

[0047] Optional, in Figure 3 In the example, the driving mechanism 400 further includes a connecting assembly 410 connected between the driving member 402 and the feeding assembly 500, and the connecting assembly 410 includes: A connecting plate 411, the other end of the telescopic rod 403 is vertically fixed to one side of the connecting plate 411; the connecting plate 411 and the inner side wall of the housing 401 are arranged to slide relative to each other; A sealing rod 412, one end of which is vertically fixed to the other side of the connecting plate 411, and the other end of which is provided with a threaded through hole; A connecting block 413 is fixedly connected to the feeding assembly 500 and is threadedly connected to the threaded through hole.

[0048] Specifically, the connecting plate 411 is used to connect the telescopic rod 403 and the sealing rod 412. The other end of the telescopic rod 403 is vertically fixed to one side of the connecting plate 411, and the connecting plate 411 is relatively slidably arranged with the inner side wall of the housing 401, and the connecting plate 411 is sealed and connected with the inner wall of the housing 401. The material of the connecting plate 411 should be selected from corrosion-resistant and high-temperature resistant materials, such as stainless steel or special plastics. One end of the sealing rod 412 is vertically fixed to the other side of the connecting plate 411, and the other end is provided with a threaded through hole. When the reaction needs to be started, the control unit sends an instruction to the driving member 402, the driving member 402 pushes the telescopic rod 403 to extend, and the telescopic rod 403 drives the connecting plate 411 and the sealing rod 412 to move (it can be downward movement in the figure), and finally pushes the feeding assembly 500 into the reaction area of ​​the hydrogen production unit 200, so that the hydrogen production agent contacts the reactant (such as water), and starts a chemical reaction to generate hydrogen. When the internal pressure of the hydrogen storage unit 100 reaches the set value, the control unit will send a stop signal. After receiving the stop signal, the driving member 402 drives the telescopic rod 403 to retract, and the telescopic rod 403 drives the connecting plate 411 and the sealing rod 412 to move (such as upward movement), and finally pulls the feeding assembly 500 out of the reaction area, and stops supplying the hydrogen production agent to the hydrogen production unit 200.

[0049] exist Figure 3 In the example shown, the driving mechanism 400 is disposed on the top of the hydrogen production unit 200. Providing the driving mechanism 400 on the top can fully utilize the space above the hydrogen production unit and reduce the floor space.

[0050] Optionally, the connection block 413 can also be used to remove the feeding assembly 500, directly add the hydrogen-generating agent into the feeding assembly 500, and then re-thread the connection block 413 with the sealing rod 412 after the addition is completed.

[0051] Optional, in Figure 3 In the embodiment, the driving mechanism 400 is connected to the feeding assembly 500 through a connection port provided in the hydrogen production unit 200. The sealing rod 412 passes through the connection port and is connected to the connecting plate 411 and the oil assembly respectively.

[0052] Optionally, the hydrogen production unit 200 is further provided with a feed port 420 for connecting an external feed pipe to input the reactant, for example, a water inlet that can be connected to a water pipe for water injection. A first pipe plug 421 is also installed on the feed port 420 to seal the hydrogen production unit 200. After the reactant enters the hydrogen production unit 200 through the feed port 420, the first pipe plug 421 seals the feed port 420.

[0053] As an example, the feed port 420 can be set at the top of the hydrogen production unit 200, or at other locations, and the specific selection depends on the actual application requirements. The operator can add the reactant directly from the top, which is convenient and quick. The top position is far away from the reaction area, reducing the interference of the feeding process on the reaction. The feed port 420 can also be set at the side position so that it can be flexibly arranged according to the actual layout without being limited by the top space. However, the side position is closer to the reaction area, and the feeding process may cause certain interference to the reaction.

[0054] Optionally, the hydrogen production unit 200 is also provided with a feed port 430; the feeding assembly 500 is connected to the feed port 430 through a feed pipe 432 for feeding a hydrogen-producing agent into the feeding assembly 500. A second pipe plug 431 is also provided corresponding to the feed port 430, and its function is the same as that of the first pipe plug 421, which will not be described in detail here. The hydrogen production process is as follows: first, the hydrogen-producing agent is added to the feeding assembly 500 through the feed port 430. The hydrogen-producing agent can be magnesium and magnesium alloys, aluminum and aluminum alloys, zinc and zinc alloys, and calcium and calcium alloys. The hydrides corresponding to the metals and alloys, such as MgH2, CaH2, MCH (magnesium calcium hydride), etc., are prepared in the shape of powder, block, strip, etc.; open the second pipe plug 431, and quickly add the hydrogen-producing agent to the feeding assembly 500 of the mesh cylindrical structure through the feed port 430 and the feed pipe 432. The feeding assembly 500 does not contact the reactants in the hydrogen production unit 200 when no reaction occurs.

[0056] Optional, in Figure 4 In the example, the bottom of the hydrogen production unit 200 is provided with a discharge port 202 for discharging the reactant. In some embodiments, a manual or automatic valve is provided at the discharge port 202 to control the discharge process of the reactant. The manual valve can be opened and closed manually by the operator as needed, while the automatic valve can be controlled by a signal to achieve automatic operation. The connection between the discharge port 202 and the discharge pipeline adopts a sealing design to prevent leakage of the reactant during the discharge process and ensure the safety of the operating environment.

[0057] Optional, in Figure 1 As shown in the example, the hydrogen storage unit 100 is further provided with a gas outlet pipe 600 , and the gas outlet pipe 600 is provided with a pressure relief valve 601 and a gas outlet valve 602 .

[0058] Specifically, in some embodiments, the outlet pipe 600 is used to export the generated hydrogen to the desired place of use or storage facility. A pressure relief valve 601 is provided on the outlet pipe 600, which is used to automatically open when the internal pressure of the hydrogen storage unit 100 exceeds the set value to release excess pressure and ensure the safe operation of the system. The outlet valve 602 is used to control the outflow of hydrogen. The outlet valve 602 can be manual or automatic. The manual valve is manually opened and closed by the operator as needed, and the automatic valve can be remotely controlled by the control unit to achieve automatic operation. The design of the outlet valve 602 should ensure good sealing performance to prevent hydrogen leakage.

[0059] Optional, in Figure 2 In the example, the driving mechanism 400 further includes a power supply component 404 for supplying power to the driving mechanism 400 .

[0060] Specifically, the power supply assembly 404 provides a stable power supply for the driving mechanism 400 to ensure that the driving member 402 can work normally. The power supply assembly 404 selects a suitable power supply type according to the type of the driving mechanism 400 and the use environment.

[0061] Optional, in Figure 1 In the example, at least one photovoltaic power generation element 210 is disposed on the outer surface of the hydrogen production unit 200 .

[0062] Photovoltaic power generation device 210 uses solar energy to generate electricity, providing an additional source of energy for the entire hydrogen production device; since the hydrogen production process may require a certain amount of energy consumption, especially in controlling the feeding assembly 500, the pressure monitor 101 that monitors the gas pressure, and the gas monitor 201, power support is required. Photovoltaic power generation device 210 can convert solar energy into electrical energy to supplement the energy required for the operation of the device, reduce dependence on traditional power grids, and improve the energy self-sufficiency of the device. Especially in some remote areas or places without a stable power supply, photovoltaic power generation device 210 can ensure that the hydrogen production device can operate stably in different environments.

[0063] The use of solar energy, a renewable energy source, is in line with the concept of sustainable development. Compared with traditional fossil energy, solar energy does not produce pollutants and greenhouse gases and is environmentally friendly. By arranging photovoltaic power generation elements 210 around the hydrogen production unit 200, the space around the device can be fully utilized to maximize the collection of solar energy, improve energy utilization efficiency, and reduce negative impacts on the environment.

[0064] Optional, in Figure 4 In the example, a supporting structure 120 is further provided at the bottom of the hydrogen storage unit 100 .

[0065] The support structure 120 includes an outer frame, and a support member 121 is fixedly installed on the inner wall of the outer frame, and the support member 121 includes a support bar connected to each frame edge of the outer frame. In the figure, the outer frame example is a triangle, and there are three support bars, so that the shape of the support member 121 is Y-shaped. If in other embodiments, the outer frame is a quadrilateral, the shape of the support member 121 changes accordingly, such as a cross or an x-shape. As can be seen from the above, the support structure 120 provides a stable support structure 120 for the hydrogen storage unit 100. Since the internal pressure of the hydrogen storage unit 100 is high when storing hydrogen, a stable support is required to ensure its safe operation. The support structure 120 has high stability, can withstand the weight and internal pressure of the hydrogen storage tank, and enhance the structural strength of the hydrogen storage unit 100. The support member 121 is convenient for operators to grasp and operate when installing, moving or maintaining the hydrogen storage tank. The easy-to-grasp structural design conforms to the principles of ergonomics, allowing operators to operate more easily and improve work efficiency.

[0066] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the protection scope of the present disclosure.
