Description

Technical Field

[0001] This invention relates to the field of hydrogen production equipment technology, specifically to an electrolytic hydrogen production equipment and a hydrogen storage device. Background Technology

[0002] With the increasing demand for clean energy, water electrolysis for hydrogen production has attracted widespread attention as an important source of hydrogen energy. However, traditional hydrogen electrolyzers often suffer from poor airtightness and electrolyte leakage due to assembly errors between the sealing gaskets and the electrodes during the assembly process, affecting electrolysis efficiency and safety.

[0003] Currently, in the electrolytic hydrogen production process, the surface of the motor is corroded by ions from the aqueous solution after prolonged electrolysis, which can affect the service life of the electrodes. Furthermore, current hydrogen production processes primarily involve direct electrolysis followed by hydrogen delivery, requiring constant replenishment of the internal solution. If a seal fails, hydrogen leakage can easily occur, leading to serious safety accidents.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides an electrolytic hydrogen production device and a hydrogen storage device, which have the following beneficial effects: 1. This electrolytic hydrogen production equipment, by setting a shut-off mechanism, can create an interruption during the electrolytic hydrogen production process, and it is not a direct hydrogen delivery. Therefore, during the electrolysis process, the hydrogen is not in the delivery stage, but temporarily flows into the storage device.

[0021] 4. This hydrogen storage device, through its two chambers, allows for clear observation of the generated hydrogen and oxygen volumes, thus determining the stability of the equipment. Furthermore, the rotation of the pointer visually displays the amount of hydrogen and oxygen produced during each independent stroke. Utilizing conductive pads and arc-shaped guide plates, when abnormal production occurs, the pads and guide plates separate, disconnecting the power supply and controlling the electrodes to cut off power, thereby providing safety protection during electrolysis.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figures 1-4 An electrolytic hydrogen production device includes a reaction tank 1 and a reaction tank 2, which are interconnected. A negative electrode 8 and a positive electrode 9 are respectively installed inside the reaction tank 1 and the reaction tank 2. A power supply is provided to power the negative electrode 8 and the positive electrode 9. Both the reaction tank 1 and the reaction tank 2 are connected to a filter 3 via a delivery pipe 6, and the filter 3 has two output pipes 5. A safety mechanism 4 is installed on the reaction tank 1. The safety mechanism 4 includes a floating replenishment mechanism and a shut-off mechanism.

[0027] In this embodiment, the floating replenishment mechanism includes an infusion pipe 7. One end of the infusion pipe 7 is connected to an external water pump, and the other end of the infusion pipe 7 is connected to reaction tank 1 and reaction tank 2 respectively. A fixing sleeve 401 is provided inside reaction tank 1 and reaction tank 2. The fixing sleeve 401 is connected to the infusion pipe 7. A sliding plate 402 is slidably connected inside the fixing sleeve 401. Both the fixing sleeve 401 and the sliding plate 402 are provided with through holes 405. A floating box 406 is connected to the sliding plate 402 through a connecting rod. One end of the infusion pipe 7 is connected to an external water pump for continuously or intermittently pumping electrolyte such as deionized water or alkaline electrolyte from an external water source. The other end of the infusion pipe 7 is connected to reaction tank 1 and reaction tank 2 respectively to realize the synchronous replenishment of liquid to the two reaction tanks. Both reaction tank 1 and reaction tank 2 are equipped with a fixed sleeve 401. The fixed sleeve 401 is fixedly installed on the inner wall or tank structure of the reaction tank and connected to the outlet end of the infusion pipe 7, forming a channel for liquid inflow. A sliding plate 402 is slidably connected inside the fixed sleeve 401. The sliding plate 402 can move up and down along the inner wall of the fixed sleeve 401, and its movement is controlled by changes in the liquid level. Both the fixed sleeve 401 and the sliding plate 402 have corresponding through holes 405. When the sliding plate 402 is in the lower position, the two through holes 405 are aligned, and the electrolyte can flow into the reaction tank through the infusion pipe 7. When the sliding plate 402 moves upward, the through holes 405 are misaligned, realizing the automatic closure of the flow path. A floating box 406 is connected to the sliding plate 402 by a rigid or flexible connecting rod. The floating box 406 is placed in the electrolyte in the reaction tank, and its buoyancy changes with the liquid level. When the liquid level rises, the floating tank 406 rises due to buoyancy, causing the sliding plate 402 to move upward via a connecting rod, gradually closing the electrolyte replenishment channel. When the liquid level drops due to electrolyte consumption, the floating tank 406 descends accordingly, causing the sliding plate 402 to move downward and reopen the through hole 405, thus achieving automatic and intermittent electrolyte replenishment. This mechanism, through purely mechanical buoyancy feedback, achieves self-regulation of the liquid level and automation of electrolyte replenishment without the need for external sensors or electronic control units. It has a simple structure, reliable response, and is suitable for continuous or intermittent electrolytic hydrogen production systems.

[0028] Furthermore, a filter rack 403 is installed on the inner wall of reaction tank 1 below the floating tank 406, and a limiting strip 404 is installed on the inner wall of reaction tank 1 above the floating tank 406. The filter rack 403, fixedly installed at an appropriate height on the inner wall of the reaction tank, can have a mesh or grid structure. It supports and limits the lowest downward position of the floating tank 406, preventing excessive sinking that could affect the normal reset of the replenishment mechanism or interfere with the tank bottom structure. Simultaneously, the filter rack 403 also functions as a preliminary filter, blocking large particles or sediments that may enter the area below the floating tank 406, preventing them from entering the infusion pipeline or affecting the movement flexibility of the floating tank. The limiting strip 404, an annular or partially protruding structure, is fixedly installed on the inner wall of the tank and limits the upper limit of the floating tank 406 when the liquid level rises. When the liquid level reaches the set maximum level, the floating tank 406 rises and eventually contacts the limit bar 404, preventing it from moving further upward. This, along with the linkage mechanism, stabilizes the sliding plate 402 in a position where the replenishment orifice 405 is completely closed, ensuring that the replenishment action reliably stops when the electrolyte is sufficient. The limit bar 404 and the filter frame 403 together constitute the mechanical travel limit for the vertical movement of the floating tank 406, ensuring that it floats smoothly within the set range, thereby guaranteeing the accuracy of the replenishment control and the stability of the system operation.

[0029] Furthermore, the cleaning component includes a support rod 408, with cleaning sleeves 410 connected to both ends of the support rod 408. The two cleaning sleeves 410 are slidably connected to the surfaces of the negative electrode 8 and the positive electrode 9, respectively. An extension rod 412 is connected to the support rod 408, and an arc-shaped strip 409 is connected to the surface of the extension rod 412. One end of the arc-shaped strip 409 is connected to a sliding plate 402. When the electrolyte level drops due to consumption, the floating box 406 drives the sliding plate 402 to move downward. The sliding plate 402, through the arc-shaped strip 409 connected to it, pulls the extension rod 412 downward synchronously. The downward movement of the extension rod 412 causes the support rod 408, which is rigidly connected to it, to descend, thereby driving the cleaning sleeves 410 at both ends to slide downward along the surfaces of the negative electrode 8 and the positive electrode 9. Conversely, when the liquid level rises and the sliding plate 402 moves upward, the arc-shaped bar 409 pushes the extension rod 412 and the support rod 408 to rise, causing the cleaning sleeve 410 to slide upward. By mechanically converting the liquid level change into the reciprocating motion of the cleaning sleeve 410, the cleaning component can automatically and continuously scrape off bubbles, deposits, or passivation layers attached to the electrode surface during the electrolysis process by taking advantage of the natural cycle of electrolyte consumption and replenishment.

[0030] Furthermore, the shut-off device includes a power sleeve 411, inside which a small piston 413 is slidably connected. The small piston 413 is connected to an extension rod 412. The top of the extension rod 412 passes through the power sleeve 411 and is connected to a rack 415 via a connecting rod. A drive gear 416 meshes with the rack 415. A valve shaft 417 is fixedly connected to the axis of the drive gear 416. A ball valve 407 is installed on the delivery pipe 6. A valve disc is connected to the end face of the valve shaft 417 and is located inside the ball valve 407. A compression spring 414 is connected to the small piston 413 and is located inside the power sleeve 411. The top of the extension rod 412 extends upward and passes through the top sealing structure of the power sleeve 411. Its protruding end is connected to a rack 415 via a connecting rod mechanism, so that the vertical displacement of the extension rod 412 can be converted into the vertical movement of the rack 415. The rack 415 meshes with a drive gear 416, thereby converting linear motion into rotational motion. A valve shaft 417 is fixedly connected to the shaft of the drive gear 416. The rotation of the valve shaft 417 directly controls the opening and closing of the valve. A ball valve 407 is installed on the delivery pipe 6 along the critical path of gas delivery. The ball valve 407 has a rotatable valve disc, or ball, inside its valve chamber. The end of the valve shaft 417 extends into the ball valve 407 and is fixedly connected to the valve disc. Therefore, when the drive gear 416 drives the valve shaft 417 to rotate, the valve disc rotates accordingly, thereby opening or closing the gas passage of the delivery pipe 6. To provide the necessary restoring force and operational stability, a compression spring 414 is connected to the small piston 413. The compression spring 414 is located inside the power sleeve 411, typically mounted above or below the small piston 413. When the liquid level drops, the extension rod 412 drives the small piston 413 downward, compressing the spring 414 to store energy. When the liquid level rises, the downward pressure on the small piston 413 decreases or disappears, and the spring 414 releases its elastic potential energy, assisting in pushing the small piston 413 and the entire linkage mechanism to reset. This drives the rack 415 to move in the opposite direction, and through gear transmission, rotates the valve shaft 417, changing the opening and closing state of the ball valve 407. When the electrolyte is sufficient and the liquid level is high, the mechanism closes the ball valve 407, suspending gas output, and the produced gas is temporarily stored in downstream devices. When the electrolyte is consumed and the liquid level drops to the threshold, the mechanism resets under the action of buoyancy and the spring, driving the ball valve 407 to open and resuming gas delivery. This intermittent "electrolysis-storage-delivery" operation mode effectively separates peak gas production from delivery periods, reducing pipeline pressure fluctuations, leakage risks, and impacts on downstream systems that may result from continuous delivery, thereby significantly improving the safety and controllability of the entire hydrogen production process.

[0031] Example 2

[0032] Please see Figures 5-8A hydrogen storage device includes a storage tank 10. The two ends of the storage tank 10 are connected to a reaction tank 1 and a reaction tank 2 via connecting pipes 101. An internal partition 104 divides the storage tank 10 into two chambers: chamber one for storing hydrogen and chamber two for storing oxygen. The storage tank 10 is typically a horizontal or vertical sealed pressure-resistant container. Its two ends are connected to the gas output terminals of reaction tank 1 and reaction tank 2 via connecting pipes 101 to receive the hydrogen and oxygen generated during electrolysis, respectively. To ensure safe isolation, the two connecting pipes 101 are designed and installed to ensure independent gas flow directions, preventing hydrogen-oxygen mixing. The partition 104 tightly divides the interior of the storage tank 10 into two independent chambers: chamber one and chamber two. The first chamber is connected to the hydrogen-generating reaction vessel (e.g., typically the vessel containing the negative electrode) via a corresponding connecting pipe 101, and is specifically used for receiving and storing hydrogen. The second chamber is connected to the oxygen-generating reaction vessel (e.g., typically the vessel containing the positive electrode) via another connecting pipe 101, and is specifically used for receiving and storing oxygen. The sealing design of the partition 104 is crucial, as it fundamentally and physically isolates hydrogen and oxygen from direct contact inside the storage tank 10, effectively eliminating the risk of mixing, backfire, or even explosion during storage, thus forming the basic safety barrier of this device.

[0033] In this embodiment, a pressure storage component is provided inside the storage tank 10. The pressure storage component includes two large pistons 105, both of which are connected to a partition 104 via compression springs 106. A display bar 102 is provided on the storage tank 10. Specifically, one end of each compression spring 106 is fixed to the corresponding side of the partition 104, and the other end is connected to the end face of the corresponding large piston 105 facing the partition 104. In the initial state, when there is no gas or low pressure in the tank, the compression springs 106 are in a naturally extended or slightly compressed state, pushing the large pistons 105 towards the end of the cavity away from the partition 104. When the gas generated by electrolysis enters the first and second cavities respectively, the gas pressure acts on the "inlet side" end face of the large pistons 105, overcoming the elastic force of the compression springs 106, pushing the large pistons 105 towards the "spring side", compressing the springs 414, thereby providing a controlled and elastic storage space for the gas. This process not only stores gas but also absorbs pressure fluctuations through spring compression, buffering and stabilizing system pressure. To visually reflect the gas storage volume, a display bar 102 is provided on the cylinder body of storage tank 10 along the piston movement direction, corresponding to the "spring side" area of ​​each cavity. This display bar 102 is typically a transparent or graduated observation window, or an external mechanical indicating mechanism. As the large piston 105 is pushed by the gas, its position change can be directly observed through the display bar 102, thus visually indicating the temporary storage volume or relative pressure of hydrogen and oxygen in the corresponding cavity, providing clear status indications for the operator. When ball valve 407 opens, the large piston 105, compressed by the spring, will return to its original position and slide, compressing the temporarily stored gas, which is then transported through the connecting pipe of delivery pipe 6.

[0034] Furthermore, each of the two large pistons 105 is connected to a transverse rack 107, on which gears 111 (second gear) and 110 (first gear) mesh respectively. A pointer 108 is connected to the axis of gear 111 via a connecting rod, and a pointer 109 is connected to the axis of gear 110 via a sleeve. An indicator sleeve 103 is rotatably connected to gears 110 and 111, and is mounted on the display bar 102. When hydrogen or oxygen enters its storage chamber and pushes the corresponding large piston 105 to move, the transverse racks 107 connected to the large piston 105 drive the meshing gears to rotate. The rotation of the gears, through the connecting rod or sleeve at the axis, causes the corresponding pointer to rotate on the scale of the display bar 102. The angle of pointer rotation is proportional to the displacement of the large piston 105, thus converting the gas volume or piston position, which cannot be directly observed, into a clear and easy-to-read scale pointer indication. By observing the turning positions of pointer 108 and pointer 209 respectively, operators can intuitively and quantitatively read the independent production or temporary storage volume of hydrogen and oxygen, realizing real-time, separate metering and monitoring of the gases produced in the electrolysis process.

[0035] Furthermore, an arc-shaped guide plate 113 is connected to the side of gear one 110, and a patch 112 is connected to the side of gear two 111. The patch 112 and the arc-shaped guide plate 113 are slidably connected, and the power supply is electrically connected to the negative electrode 8 and the positive electrode 9 through the patch 112 and the arc-shaped guide plate 113. The patch 112 and the arc-shaped guide plate 113 form a sliding electrical contact pair in a slidably connected manner. During normal operation of the device, as the two large pistons 105 move to different positions due to the different yields of hydrogen and oxygen, they drive gear one 110 and gear two 111 to rotate to specific angles respectively. During this process, the patch 112 always slides on the arc-shaped conductive surface of the arc-shaped guide plate 113, maintaining the physical connection of the circuit. The positive and negative terminals, which are not shown in the power supply diagram but are mentioned in the instruction manual, are connected to the patch 112 and the arc-shaped guide plate 113 respectively through wires. Specifically, the sliding electrical contact pair is connected in series in the electrolysis power supply circuit. One pole of the power supply is connected to the patch 112 via a line, and the other pole is connected to the arc-shaped guide plate 113 via a line. The patch 112 and the arc-shaped guide plate 113 are then electrically connected to the negative electrode 8 and the positive electrode 9 in the electrolytic cell via other wires, respectively. Therefore, the on / off state of the entire electrolysis circuit is actually controlled by the contact condition of this pair of sliding electrical contacts. Under ideal electrolysis conditions, the volume ratio of hydrogen to oxygen produced should be 2:1. This will drive gear one 110 and gear two 111 to rotate in a preset ratio, ensuring that the patch 112 always slides within the effective contact area of ​​the arc-shaped guide plate 113, keeping the circuit conductive and allowing electrolysis to continue. If an abnormality occurs in the system, such as a leak in a reaction vessel causing an imbalance in gas production or a mismatch in the ratio, the relative rotation angle of the two gears will deviate from the normal range. When the deviation exceeds the set tolerance, the patch 112 will slide away from the end of the arc-shaped guide plate 113, causing the sliding electrical contact pair to separate, thereby automatically cutting off the power supply circuit to the negative electrode 8 and the positive electrode 9, and stopping the electrolysis process immediately. This purely mechanical electrical interlocking can quickly cut off the power when an abnormal gas production ratio is detected without the need for external sensors or controllers, and is an efficient and reliable intrinsically safe safety protection measure.

[0036] The working principle is as follows: First, the power supply is generally a green and energy-saving power source, such as solar and wind power, which is transmitted to the positive electrode 9 and the negative electrode 8 through the line. Then, the electrolyte is delivered from the external water source to the interior of the reaction tank 1 and the reaction tank 2 through the water pump on the infusion pipe 7. When the liquid inside reaches a certain liquid level, the floating box 406 will rise due to the buoyancy of the liquid surface until it abuts against the limit bar 404. At the same time, the floating box 406 will drive the sliding plate 402 to move upward through the connecting rod. After the sliding plate 402 moves upward, it will close the through hole 405 on the fixed sleeve 401. Therefore, the outlet of the infusion pipe 7 will be blocked, restricting the addition of electrolyte. When the electrodes are energized, they electrolyze the electrolyte in the two reaction tanks. The negative electrode 8 will produce hydrogen, while the positive electrode 9 will produce oxygen. The generated gases will enter through the conveying pipe 6 connecting the top of the two reaction tanks, then enter the filter 3. After filtration, the gases will be discharged through the two output pipes 5 to the external collection container. Throughout the electrolysis process, a shut-off device is installed. When the floating tank 406 is lifted by the buoyancy of the liquid surface, it will indirectly move the sliding plate 402 upward via a connecting rod. This upward movement of the sliding plate 402 will then drive the extension rod 412 upward via the arc strip 409. The upward movement of the extension rod 412 will then drive the rack 415 upward. Through gear meshing, this will drive the valve shaft 417 to rotate, which in turn will rotate the valve disc inside the ball valve 407, thus directly sealing the passage of the conveying pipe 6 and shutting off the direct conveying pipeline. As the electrolyte inside the reaction vessel is consumed and the liquid level drops, the floating tank 406 also descends. This causes the rack 415 to move downwards, controlling the reverse rotation of the drive gear 416, which in turn opens the ball valve 407, controlling the output of hydrogen and oxygen. Simultaneously, the up-and-down movement of the extension rod 412 also causes the cleaning sleeve 410 on the connected support rod 408 to move up and down. Therefore, the cleaning sleeve 410 slides up and down on the electrode surface, thus cleaning the electrode surface. The cleaning sleeve 410 and the support rod 408 are insulating structures.

[0037] The entire device is also equipped with a storage device. The purpose of the storage device is to provide a temporary storage cavity for the gas generated by electrolysis during the automatic valve closing phase. When the ball valve 407 is automatically closed, the electrolysis process still continues, and the generated gas will enter the interior of the storage tank 10 through the two connecting pipes 101, entering the interior of cavity one and cavity two respectively. The pressure generated after the gas is generated will directly push the large piston 105 to compress the compression spring 106. During the electrolysis hydrogen production phase, the oxygen and hydrogen produced are of different quantities. Two molecules of water will produce one molecule of oxygen and two molecules of hydrogen. Therefore, based on the volume ratio of the generated gas, it can be observed that the lateral sliding distance of the large piston 105 in the two different storage cavities will be different, and the movement is proportional. A pointer is also provided to visually display the internal volume parameters. When the large piston 105 moves, it will synchronously drive the horizontal rack 107 to move. The two horizontal racks 107 are respectively meshed on gear one 110 and gear two 111. Therefore, the distance that the two large pistons 105 move will visually change the angle of the rotating pointer, thereby controlling pointer one 108 and pointer two 109 to switch to different angles. During the stage from valve closing to opening, this period is basically fixed because the consumption of liquid level is controlled by the electrolysis of the electrode. During the rotation of the two pointers, the patch 112 will rotate and contact the surface of the arc-shaped guide plate 113. If there is a leak in the two reaction vessels, that is, gas leakage, the angle deviation between the rotation of patch 112 and arc-shaped guide plate 113 will become larger, and patch 112 and arc-shaped guide plate 113 will separate, disconnecting the power supply. At this time, the electrode will be de-energized, thus forming a protection.
