Abstract
Description
Technical Field
[0001] This invention relates to the field of renewable energy hydrogen production technology, specifically to a renewable energy-driven air-water electrolysis hydrogen production device. Background Technology
[0002] With the world's over-reliance on traditional fossil fuels and the increasingly prominent environmental problems they cause, such as climate change and air pollution due to greenhouse gas emissions, seeking clean and renewable energy alternatives has become an urgent need for global development. Renewable energy, especially photovoltaic (solar photovoltaic) and wind power, has received widespread attention and application exploration due to its significant advantages such as sustainability and zero emissions. Among many application areas, using renewable energy to produce hydrogen is considered a highly promising development direction because hydrogen, as a clean and efficient energy carrier, plays an important role in energy transition and achieving a low-carbon economy.
[0003] However, in existing renewable energy-driven air-to-water electrolysis hydrogen production devices, the connection between the conduit and the equipment is a critical node for ensuring stable system operation. Because the conduit needs to withstand the effects of medium pressure, vibration, and changes in ambient temperature over a long period of time, the sealing of the connection is prone to failure, leading to water leakage, gas leakage, and other malfunctions. Such malfunctions not only waste the medium but may also cause abnormal equipment operation and reduced efficiency. In scenarios involving precision processes such as water electrolysis, the failure of the connection seal may affect the stability of the incoming water, interfere with the electrolysis reaction process, and even bring safety hazards. Summary of the Invention
[0004] Therefore, the present invention provides a renewable energy-driven air-water electrolysis hydrogen production device to solve the above-mentioned problems in the prior art.

[0006] Furthermore, the movable component includes: a fixing strip, which is fixedly installed on the inner side of the sealing ring, and an abutment block is hinged to the inner side of the fixing strip, and a sealing block is slidably connected inside the abutment block.
[0007] Furthermore, a spiral spring is fixedly installed on the outer side of the contact block, and the spiral spring is fixedly installed on the inner wall of the fixing strip.
[0008] Furthermore, a movable spring is fixedly installed inside the sealing block, and the movable spring is fixedly installed inside the contact block.
[0009] Furthermore, the fixing component includes: a fixing block, which is fixedly installed on the top of the fixing plate, and a plurality of positioning blocks are fixedly installed inside the fixing block.
[0010] Furthermore, a handle is fixedly installed on the top of the turntable, a limiting block is fixedly installed at the bottom of the handle, an insert is slidably connected inside the limiting block, the insert is inserted into the inner side of several positioning blocks, and a control strip is fixedly installed on the surface of the insert.
[0011] Furthermore, a reset spring is fixedly installed on the top of the insertion block, and the reset spring is fixedly installed inside the limiting block.
[0012] Furthermore, the surface of the fixed disk has a groove, and the surface of the turntable has an arc-shaped groove.
[0013] Furthermore, the cross-section of the sealing ring is semi-arc-shaped, four sealing rings are provided, and several fixing strips are provided on the inner side of the sealing ring, and the number of fixing strips is the same as the number of sealing blocks.
[0014] Furthermore, a pipe is installed on the right side of the water electrolysis device, and two pipes are provided.
[0015] Compared with existing technologies, it has the following advantages:
[0016] 1. This renewable energy-driven air-to-water electrolysis hydrogen production device, through the arrangement of movable components, allows for sealing of the conduit connection. A fixed shaft is fixed to the conduit surface, supported by a fixed disc. Manual rotation of the turntable causes a sliding rod to move. Because it is hinged to a moving block, the moving block moves accordingly, and its outer telescopic rod moves synchronously. A fixed spring acts as a buffer and stabilizing structure. The sealing ring moves closer to the conduit connection along with the telescopic rod. Multiple sealing rings are joined to form a circle that fits snugly around the perimeter, achieving a seal and preventing water and gas leakage. This ensures stable water and gas delivery, provides stable water intake conditions for the water electrolysis process, and enhances the safety and reliability of the device operation.
[0017] 2. This renewable energy-driven air-water electrolysis hydrogen production unit, through the setting of a moving component, is used for further sealing adjustment. The fixed strip is installed inside the sealing ring, and the contact block is in the initial position under the action of the spiral spring. The sealing block is also in the same position under the action of the movable spring. When the seal at the conduit connection is not good, the sealing block slides inside the contact block under the action of the relevant force, and the contact block will also rotate appropriately, dynamically adjusting the seal. This avoids gaps and minor leaks at the connection due to equipment operation factors, ensuring high efficiency in hydrogen production and improving the adaptability and reliability of the unit.
[0018] 3. This renewable energy-driven air-water electrolysis hydrogen production device, through the setting of fixed components, after the sealing operation is completed by the movable and moving components, the fixed components play a role. The fixed block is on the top of the fixed plate, and its positioning block serves as a reference. The operation control bar makes the insertion block slide within the limiting block. Inserting the positioning block can limit the rotation of the turntable, stabilize the sealing state, and the return spring facilitates the reset of the insertion block for easy reoperation. It can avoid damage to the sealing structure, liquid or gas leakage, ensure stable operation of the device, extend equipment life, and improve operational convenience and flexibility.

[0030] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.
[0031] like Figures 1 to 8 As shown, a renewable energy-driven air-water electrolysis hydrogen production device includes a frame 1. The water in the water electrolysis device 11 comes from an air-water extraction device, enabling automatic water extraction and hydrogen production. Inside the frame 1, there is a fan 2, a filter 3, and a condenser 4. A controller 5 is installed on the top of the frame 1. A water storage tank 6 is connected to the outside of the frame 1 via a conduit 12. A liquid level monitor 10 is installed on the outside of the water storage tank 6. The water electrolysis device 11 is connected to the outside of the water storage tank 6 via a conduit 12. The device also includes a movable component 7 for sealing the connection of the conduit 12; a moving component 8 for adjusting and sealing the connection of the conduit 12; and a fixed component 9 for restricting the movable component 7 and the moving component 8 after use.
[0032] First, the movable component 7 includes: a fixed shaft 71, which is fixedly installed on the surface of the conduit 12. A fixed disk 72 is fixedly installed on the surface of the fixed shaft 71. A turntable 73 is rotatably connected to the outside of the fixed disk 72. A slide rod 74 is slidably connected inside the turntable 73. A moving block 75 is hinged to the inside of the slide rod 74. The moving block 75 passes through the fixed disk 72. A telescopic rod 76 is fixedly installed on the outside of the moving block 75. A fixing spring 77 is fixedly installed inside the telescopic rod 76. A sealing ring 78 is fixedly installed on the surface of the telescopic rod 76. The fixed spring 77 inside the telescopic rod 76 can be used to adjust the position of the connection point of the conduit 12 to different lengths.
[0033] Secondly, the movable component 8 includes: a fixing strip 81, which is fixedly installed on the inner side of the sealing ring 78. An abutment block 82 is hinged to the inner side of the fixing strip 81. A sealing block 83 is slidably connected inside the abutment block 82. A spiral spring 84 is fixedly installed on the outer side of the abutment block 82. The spiral spring 84 is fixedly installed on the inner wall of the fixing strip 81. The abutment block 82 can be adjusted when the conduit 12 is deformed or the connection shape at the connection point is different through the spiral spring 84 on the outer side of the abutment block 82.
[0034] Furthermore, a movable spring 85 is fixedly installed inside the sealing block 83. The movable spring 85 is fixedly installed inside the contact block 82. Through the movable spring 85 inside the sealing block 83, the sealing block 83 can always maintain a good sealing state for conduits 12 of different sizes.
[0035] Furthermore, the fixing component 9 includes: a fixing block 91, which is fixedly installed on the top of the fixing plate 72. Several positioning blocks 92 are fixedly installed inside the fixing block 91. The positioning blocks 92 can be used to position the insert 95 when it is moved to different positions. A handle 93 is fixedly installed on the top of the turntable 73. A limiting block 94 is fixedly installed on the bottom of the handle 93. An insert 95 is slidably connected inside the limiting block 94. The insert 95 is inserted into the inner side of the several positioning blocks 92. A control strip 96 is fixedly installed on the surface of the insert 95.
[0036] Furthermore, a reset spring 97 is fixedly installed on the top of the insertion block 95. The reset spring 97 is fixedly installed inside the limiting block 94. The reset spring 97 on the top of the insertion block 95 can achieve the effect of resetting when the insertion block 95 is pulled.
[0037] Finally, the surface of the fixed plate 72 is provided with a groove 720, which allows the moving block 75 to slide linearly. The surface of the turntable 73 is provided with an arc-shaped groove 730, which allows the turntable 73 to slide against the sliding rod 74 when it rotates. The sealing ring 78 has a semi-arc cross-section and four sealing rings are provided. Several fixing strips 81 are provided on the inner side of the sealing ring 78, and the number of fixing strips 81 is the same as the number of sealing blocks 83. The sealing rings 78 can be used to adapt to and precisely fit the surfaces of conduits 12 of different sizes and shapes.
[0038] Two pipes 13 are installed on the right side of the water electrolysis device 11.
[0039] The air-to-water electrolysis hydrogen production device driven by this renewable energy source utilizes renewable energy sources such as photovoltaic and wind power to drive the operation of the entire device. The input electrical energy is adjusted by the controller 5 to provide the required operating current and voltage for the air-to-water device, the water storage device, and the water electrolysis device 11. The air-to-water device draws in air through the fan 2, and after the filter 3 removes dust and other impurities, the air enters the condenser 4 to condense the water and collect it in the water storage tank 6. The water storage tank 6 can control the water input of the water electrolysis device 11 through the liquid level monitor 10. Subsequently, the water electrolysis device 11 uses the water extracted from the air to electrolyze and produce hydrogen. The generated oxygen and hydrogen are output through different pipes 13, realizing self-water hydrogen production. When sealing of the connection of conduit 12 is required, the operating component 7 comes into play. The fixed shaft 71 is fixed to the surface of conduit 12, and the supporting fixed plate 72 provides a mounting base for other components. The turntable 73 is manually rotated, causing the internally slidingly connected slide rod 74 to slide. Since the slide rod 74 is hinged to the moving block 75, the sliding of the slide rod 74 will drive the moving block 75 to move on the fixed plate 72. The telescopic rod 76 on the outside of the moving block 75 will move synchronously with the moving block 75, thereby moving towards the surface near the connection between conduit 12 and the equipment. The telescopic rod 76 moves, and the fixed spring 77 inside can buffer and maintain the stability of the structure to a certain extent. At the same time, the sealing ring 78 on the surface of the telescopic rod 76 will gradually approach the connection of the conduit 12 as the telescopic rod 76 moves. Finally, multiple sealing rings 78 cooperate with each other to form a circle and fit tightly around the connection of the conduit 12 to achieve a sealing effect, prevent water or gas leakage at the connection, ensure stable delivery of water or gas in the conduit 12, provide stable water inlet conditions for the subsequent water electrolysis process, and improve the safety and reliability of the device operation.
[0040] The movable component 8 is used to further adjust and seal the connection of the conduit 12. The fixing strip 81 is installed inside the sealing ring 78. The abutment block 82, which is hinged inside the fixing strip 81, is initially positioned by the action of the spiral spring 84. The sealing block 83, which is slidably connected inside the abutment block 82, is also initially positioned by the action of the internal movable spring 85. When the connection of the conduit 12 is not sealed tightly due to various factors, the sealing block 83 will slide inside the abutment block 82 under the action of the movable spring 85 and external water flow, air flow pressure, etc. The abutment block 82 will also rotate appropriately at the fixing strip 81 according to the actual situation. Through the adaptive movement and abutment of the sealing block 83, The flexible rotation of block 82 dynamically adjusts the seal at the connection of conduit 12, ensuring it maintains a good seal at all times. This further ensures the sealing and stability of water and gas transport within the entire device, preventing minor gaps from appearing at the connection of conduit 12 due to factors such as vibration and thermal expansion and contraction during long-term operation. Even small leaks can accumulate over time and affect the efficiency of hydrogen production through water electrolysis. For example, they can cause unstable water flow, affecting the electrolysis reaction, or gas leaks can alter the pressure environment within the device, interfering with the normal operation of the equipment. This ensures the continuous high efficiency of the hydrogen production process and improves the adaptability and reliability of the device operation.
[0041] After the movable component 7 and the moving component 8 complete the sealing and adjusting sealing operations at the connection of the conduit 12, the fixing component 9 begins to function to prevent accidental rotation of the turntable 73 and loosening of the sealing structure. A fixing block 91 is installed on top of the fixing plate 72, with several positioning blocks 92 inside serving as positioning references. A sliding insert 95 is located within the limiting block 94 below the handle 93 on the top of the turntable 73. By manually operating the control bar 96, the insert 95 can slide within the limiting block 94. When the insert 95 is inserted into the inner side of the positioning block 92, it restricts the rotation of the turntable 73, thereby ensuring that the movable component 7 remains in its current position. The sealing state of the movable component 8 is ensured, which also indirectly ensures the stability of the adjustment sealing state. The reset spring 97 on the top of the plug 95 can facilitate the reset of the plug 95 when the restriction needs to be released, so that the turntable 73 can be operated again. This avoids the accidental rotation of the turntable 73, which may cause the sealing ring 78 in the movable component 7, which was originally tightly fitted at the connection of the conduit 12, to change position, destroy the sealing structure formed by the joint, and create gaps, which may lead to liquid or gas leakage, affecting the normal operation of the entire device and the efficiency of water electrolysis to produce hydrogen. This ensures the stable operation of the device, extends the service life of the equipment, and improves the convenience and flexibility of operation.

Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
