Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0029] According to a first aspect of this application, embodiments of this application provide a water replenishment device 100.

[0030] Reference Figures 1 to 5 , Figure 1 A perspective view of the water replenishment device 100 provided in an embodiment of this application; Figure 2 A perspective view of the water replenishment device 100 provided in an embodiment of this application from another angle;

[0031] Figure 3 A schematic diagram of the structure of the water replenishment device 100 with the outer casing 1 concealed, as provided in an embodiment of this application;

[0032] Figure 4 Front view of the water replenishment device 100 provided for an embodiment of this application; Figure 5 A top view of a water replenishment device 100 provided for an embodiment of this application.

[0033] The water supply device 100 includes a housing 1, a water tank 2, an inlet pipe 3, and an outlet pipe 4. The housing 1 is provided with an inlet 101 and an outlet 102. The water tank 2 is disposed inside the housing 1, and the inlet pipe 3 connects the inlet 101 and the water tank 2 to supply water to the water tank 2. The outlet pipe 4 connects the water tank 2 and the outlet 102 to supply water to the electrolyzer of the hydrogen production device 200.

[0034] It can be understood that the outer casing 1 is the outer frame of the water replenishment device 100, and the outer casing 1 surrounds the water tank 2. Specifically, the outer casing 1 can be a closed structure surrounding the water tank 2 to isolate the water tank 2 from the external environment. For example, in... Figures 1 to 5 The top cover is obscured to show the internal structure of the water replenishment device 100.

[0035] The water tank 2 can be made of polyethylene or polypropylene, and the outer shell 1 can be made of galvanized steel sheet.

[0036] The water used is pure water, which is the raw material for hydrogen production through water electrolysis. Pure water has low conductivity, and when using pure water as a raw material, the conductivity can be improved by adding electrolytes (such as sodium hydroxide, potassium hydroxide, or sulfuric acid). The preparation of pure water usually requires treatment processes such as reverse osmosis, ion exchange, or distillation to remove impurities and dissolved substances from the water.

[0037] In the embodiments of this application, by placing the water tank 2 inside the outer casing 1, the risk of the water tank 2 coming into contact with external alkaline substances is reduced, and the water tank 2 is less prone to corrosion. This helps to reduce the risk of the water replenishment device 100 having a shortened service life and leaking due to corrosion. Furthermore, the outer casing 1 can also prevent water from leaking to the outside when the water tank 2 leaks, reducing the risk of damage to other components.

[0038] The water tank 2 integrated in the hydrogen production device 200 has a limited capacity, which cannot meet the needs of large-scale hydrogen production. During large-scale hydrogen production, the capacity of the water tank 2 becomes a limiting factor, resulting in low hydrogen production efficiency or the need for frequent water replenishment.

[0039] The water replenishment device 100 provided in this embodiment can be located outside the hydrogen production device 200. The water replenishment device 100 is independent of the hydrogen production device 200, and the capacity of the water replenishment device 100 is not limited by the capacity of the hydrogen production device 200. This helps to increase the capacity of the water tank 2 to meet the large-scale hydrogen production demand and improve the hydrogen production efficiency.

[0040] Reference Figure 4 In some embodiments, the inlet 101 and the outlet 102 are located on the same side wall of the housing 1, so as to facilitate the assembly of the inlet pipe 3 and the outlet pipe 4 on the same side, reducing the assembly difficulty.

[0041] Reference Figure 1 and Figure 2 In some embodiments, the water tank 2 is spaced apart from at least one side wall of the housing 1 along the width direction X of the water replenishment device 100.

[0042] In some embodiments, along the length Y of the water replenishment device 100, the water tank 2 is spaced apart from at least one side wall of the housing 1.

[0043] For example, along the width direction X of the water replenishment device 100, the water tank 2 is spaced apart from the right side wall and front side plate of the outer casing 1.

[0044] In this embodiment, by configuring the water tank 2 to be spaced apart from at least one side wall of the outer casing 1, there can be a space between the water tank 2 and the outer casing 1, so that the water inlet pipe 3, the water outlet pipe 4 and other components can be arranged inside the outer casing 1, thereby improving the integration of the water replenishment device 100.

[0045] Since different hydrogen production devices are equipped with water tanks 2 of different sizes, in this embodiment, the water tank 2 is configured to be spaced apart from at least one side wall of the outer casing 1, making the outer casing 1 larger than the water tank 2. Therefore, the outer casing 1 can be assembled with water tanks 2 of different sizes, which helps improve the compatibility of the outer casing 1.

[0046] Reference Figure 1In some embodiments, the water replenishment device 100 further includes a level display 5, which is disposed on the housing 1. The level display 5 is located outside the housing 1 and communicates with the interior of the water tank 2 to form a communicating vessel structure, so that the liquid level in the level display 5 is consistent with the liquid level in the water tank 2.

[0047] It's understandable that liquid level refers to the height of the water.

[0048] It is understood that the liquid level display 5 is connected to the water tank 2, and water can flow from the water tank 2 into the liquid level display 5. The liquid level in the liquid level display 5 is consistent with the liquid level in the water tank 2, and the liquid level display 5 can synchronize the liquid level in the water tank 2 in real time.

[0049] Reference Figure 4 and Figure 3 In some embodiments, the liquid level display 5 includes a transparent tube 51 disposed on the housing 1 and located outside the housing 1. The water replenishment device 100 also includes a first connecting pipe 52 and a second connecting pipe 53 spaced apart along the height direction of the water tank 2. One end of the transparent tube 51 is connected to the water tank 2 through the first connecting pipe 52, and the other end is connected to the water tank 2 through the second connecting pipe 53.

[0050] The transparent tube 51 extends along the height direction of the water replenishment device 100. The top end of the transparent tube 51 is connected to the first connecting tube 52 through a connector, and the bottom end of the transparent tube 51 is connected to the second connecting tube 53 through another connector.

[0051] The transparent tube 51 can be installed on the wall of the housing 1, or it can be installed on the wall of the housing 1 via a connector.

[0052] The transparent tube 51 can be a silicone tube.

[0053] In this embodiment, the liquid level display 5 includes a transparent tube 51, which makes the liquid level in the water tank 2 visible, so that the operator can intuitively observe the liquid level in the water tank 2.

[0054] Reference Figure 4 , Figure 3 and Figure 5 In some embodiments, the outer casing 1 is also provided with an overflow port 103, and the water replenishment device 100 also includes an overflow pipe 6. The overflow port 103 is connected to the water tank 2 through the overflow pipe 6. The overflow port 103 is used to discharge excess water in the water tank 2 when the water in the water tank 2 exceeds a first threshold.

[0055] The overflow pipe 6 is located inside the outer casing 1.

[0056] In water tank 2, when the water level exceeds the set height, the overflow outlet can drain the excess water to prevent water tank 2 from overflowing due to overfilling, thereby reducing the damage to water tank 2 or other devices caused by water overflow.

[0057] Reference Figure 4 , Figure 3 and Figure 5 In some embodiments, the height of the first connecting pipe 52 is greater than the height of the second connecting pipe 53, and one end of the overflow pipe 6 is connected to the overflow port 103, and the other end is connected to the first connecting pipe 52.

[0058] It is understandable that the first connecting pipe 52 connects both the liquid level display 5 and the water tank 2, and also connects the overflow pipe 6 and the water tank 2.

[0059] In this embodiment, the first connecting pipe 52 can be used to form a communicating vessel structure between the liquid level display 5 and the water tank 2, and can also be used to drain excess water from the water tank 2, which helps to improve the integration of the water replenishment device 100.

[0060] Reference Figure 5 In some embodiments, the water replenishment device 100 further includes an electronic control valve 7, which is disposed in the water inlet pipe 3 and configured to disconnect the water inlet pipe 3 when the liquid level in the water tank 2 is higher than a first threshold, and to open the water inlet pipe 3 when the liquid level in the water tank 2 is lower than a second threshold, wherein the first threshold is greater than the second threshold.

[0061] It is understandable that the electronic control valve 7 automatically controls the opening or closing of the water inlet pipe 3.

[0062] In other words, the first threshold is the highest safe liquid level, and the second threshold is the lowest working liquid level. The first threshold is the highest liquid level that water tank 2 can hold; exceeding this level can easily cause water to overflow or damage water tank 2. Similarly, the second threshold is the lowest liquid level that water tank 2 needs to maintain; below this level, water tank 2 will not supply enough water to the hydrogen production unit 200, posing a risk of dry burning or insufficient hydrogen production.

[0063] Among them, the electronic control valve 7 can be a solenoid valve.

[0064] The installation of electronic control valve 7 helps to improve the automation level and control accuracy of the water supply device 100.

[0065] Of course, in other embodiments, a manual valve can also be set to control the opening and closing of the water inlet pipe 3.

[0066] In some embodiments, a solenoid valve (not shown in the figure) is provided on the water outlet pipe 4 to control the opening or closing of the water outlet pipe 4.

[0067] In some embodiments, the water replenishment device 100 further includes a first liquid level detector 8, which is disposed in the water tank 2 and is signal-connected to the electronic control valve 7, for detecting whether the liquid level in the water tank 2 is higher than a first threshold.

[0068] Specifically, the first liquid level detector 8 may include a first sensor, which may be a water immersion sensor. The water immersion sensor is set at the liquid level height corresponding to the first threshold and uses the principle of liquid conductivity for detection. When the probe of the second liquid level sensor is immersed in water, an alarm signal is generated, and the electronic control valve 7 controls the first pipeline to disconnect based on the alarm signal.

[0069] In some embodiments, the water replenishment device 100 further includes a second liquid level detector 9, which is disposed in the water tank 2 and is signal-connected to the electronic control valve 7, for detecting whether the liquid level in the water tank 2 is lower than a second threshold.

[0070] Specifically, the second liquid level detector 9 may include a second sensor, which may be a water immersion sensor. The water immersion sensor is set at the liquid level height corresponding to the second threshold and uses the principle of liquid conductivity for detection. When the probe of the second liquid level sensor protrudes above the liquid surface, an alarm signal is generated. The electronic control valve 7 controls the inlet pipe 3 to open based on the alarm signal.

[0071] Reference Figure 5 In some embodiments, the water replenishment device 100 further includes a controller 11, which is disposed in the housing 1, located inside the housing 1, and is signal-connected to the electronic control valve 7.

[0072] In some embodiments, the first liquid level detector 8 and the second liquid level detector 9 are signal-connected to the electronic control valve 7.

[0073] In some embodiments, the controller 11 is a relay.

[0074] In some embodiments, the controller 11 is wall-mounted, that is, the controller 11 is suspended on the side wall of the housing 1 to make full use of the space in the height direction.

[0075] In some embodiments, the water replenishment device 100 further includes a conductivity detector (not shown), which is signal-connected to the electronic control valve 7 and is used to detect whether the conductivity of the water in the water tank 2 is lower than a third threshold. The electronic control valve 7 is also configured to disconnect the water inlet pipe 3 when the conductivity of the water in the water tank 2 is lower than the third threshold. This configuration facilitates the monitoring of water conductivity.

[0076] The conductivity detector can be installed on the bottom wall of the water tank 2, with the electrodes of the conductivity detector located in the water.

[0077] Conductivity detectors may include one or more of the following: electrode-type conductivity detectors, inductive conductivity detectors, and ultrasonic conductivity detectors.

[0078] Reference Figure 4 and Figure 5In some embodiments, the water replenishment device 100 further includes a drain pipe 13 and a drain valve 10. The drain pipe 13 is disposed inside the housing 1. The drain valve 10 is disposed inside the housing 1 and located outside the housing 1. The drain valve 10 is connected to the water tank 2 through the drain pipe 13 and is configured to control the discharge of water from the water tank 2. This arrangement facilitates the emptying of water from the water tank 2 and the replacement of water.

[0079] In some embodiments, the drain valve 10, the conductivity detector, and the controller 11 are signal-connected. The controller 11 is configured to control the drain valve 10 to open when the conductivity detector detects that the conductivity of the water in the water tank 2 is unqualified, and is configured to control the drain valve 10 to remain closed when the conductivity detector detects that the conductivity of the water in the water tank 2 is qualified.

[0080] In some embodiments, the drain valve 10 and the electronic control valve 7 are both signal-connected to the controller 11. When the conductivity detector detects that the conductivity of the water in the water tank 2 does not meet the usage requirements, the controller 11 controls the electronic control valve 7 to open, thereby disconnecting the water inlet pipe 3 and stopping the supply of water to the water tank 2.

[0081] In some embodiments, the housing 1 is provided with a communication interface 14, which is electrically connected to the controller 11. The communication interface 14 is used to electrically connect to the hydrogen production device 200. The hydrogen production device 200 outputs a water supply signal through the communication interface 14. The controller 11 receives the water supply signal and controls the water pump to work. The water pump pumps the water in the water tank 2 into the water outlet pipe 4. The water is supplied to the hydrogen production device 200 through the water outlet 102.

[0082] In some embodiments, the housing 1 is provided with a power interface 15, and an external power source supplies power to the water replenishment device 100 through the power interface 15.

[0083] According to a second aspect of this application, embodiments of this application provide a hydrogen production apparatus.

[0084] Reference Figure 6 , Figure 6 This is a block diagram of a water replenishment device 100 and a hydrogen production device 200 provided in an embodiment of this application. The hydrogen production equipment includes a hydrogen production device 200 and a water replenishment device 100 provided in any embodiment of the first aspect. The water outlet 102 is connected to the electrolyzer of the hydrogen production device 200, and the water replenishment device 100 is configured to supply water to the electrolyzer of the hydrogen production device 200 through the water outlet 102.

[0085] Since the hydrogen production equipment includes a water replenishment device 100, the hydrogen production equipment has all the beneficial effects of the water replenishment device 100, which will not be elaborated here.
