Water platforms, particularly offshore platforms, have abundant renewable energy resources such as wind, solar, and wave energy, which provide ample power for water electrolysis.

[0003] The electrolysis of water to produce hydrogen produces oxygen as a byproduct, which can also be stored separately. However, considering a series of issues such as transportation and storage costs, the byproduct oxygen is mostly not effectively utilized. Summary of the Invention

A first inner cavity is formed inside the outer shell, with an open lower portion and an air outlet at the upper portion, and the water area above the air outlet forms an aeration zone; the gas-liquid mixing pipeline is located in the first inner cavity and extends vertically, and the gas-liquid mixing pipeline is provided with a first inlet and a second inlet, the first inlet being connected to the oxygen outlet; the manifold is connected to the second inlet, and the height of the second inlet is lower than that of the first inlet, so that when the medium in the gas-liquid mixing pipeline flows upward, a low-pressure zone is formed to attract the medium in the manifold; the inlet end of the manifold extends toward the dead water zone.

[0022] In order to better explain the present invention and facilitate understanding, the following Figure 1-Figure 3 , the present invention is described in detail through specific implementation methods. Figure 2 The orientation is referenced.

[0023] Example 1:

[0024] Reference Figure 1-Figure 3An embodiment of the present invention provides a water environment remediation system based on a water electrolysis hydrogen production platform, comprising a floating platform 100, an aeration device connected to the floating platform 100, and a water electrolysis device supported on the floating platform 100. The water electrolysis device includes an oxygen outlet. The aeration device includes an aeration unit, which includes a housing 1, a gas-liquid mixing pipeline 2, and a manifold 3. The housing 1 defines a first inner cavity with an open lower portion and an upper portion having an air outlet. The water area above the air outlet forms an aeration zone 10. The gas-liquid mixing pipeline 2 is located within the first inner cavity and extends vertically. The gas-liquid mixing pipeline 2 has a first inlet and a second inlet, the first inlet being connected to the oxygen outlet. The manifold 3 is connected to the second inlet, and the height of the second inlet is lower than the height of the first inlet. When the medium in the gas-liquid mixing pipeline 2 flows upward, a low-pressure zone is formed to attract the medium in the manifold 3. The inlet end of the manifold 3 extends toward a dead water area, such as below the floating platform 100, or other dead water areas, such as those formed by concave terrain.

[0025] The vertically extending gas-liquid mixing pipeline 2 can adapt to the underwater pressure gradient, so that the pressure at the upper part of the gas-liquid mixing pipeline 2 is lower than the pressure at the lower part of the gas-liquid mixing pipeline 2, thereby allowing the medium entering the gas-liquid mixing pipeline 2 to flow from the lower part of the gas-liquid mixing pipeline 2 to the upper part of the gas-liquid mixing pipeline 2.

[0026] In this embodiment, the outer shell 1 covers the outside of the gas-liquid mixing pipeline 2. The gas-liquid mixing pipeline 2 can not only receive the gas supplied by the gas supply device, but also, under the action of the low-pressure zone, enable the manifold 3 to absorb the water of the water environment to be repaired, and then enable the gas-liquid mixing pipeline 2 to output the gas and liquid medium to the first inner cavity, and then output it through the air outlet. In this way, the water in the water environment to be repaired can be filled with gas to achieve activation; at the same time, since the water in the water environment to be repaired is continuously sucked into the connecting pipe, the water body adjacent to the water of the water environment to be repaired can continuously replenish the water environment to be repaired, thereby making the water of the repaired water environment flow, cooperating with the activation effect of the gas, and further improving the ecological restoration effect of the water environment.

[0027] Specifically, after the gas and water are mixed in the gas-liquid mixing pipeline 2, they enter the aeration zone 10 of the first inner cavity through the air outlet, forming bubbles and rising, thereby realizing the aeration activation of the water body. The manifold 3 continuously draws in water from the water environment to be repaired, which causes the water level in the area to drop and forms a pressure difference. In order to make up for this pressure difference, the surrounding water will automatically flow to the area being inhaled, forming a natural water cycle. This water cycle not only promotes the flow of the water body, but also increases the dissolved oxygen content in the water body, which helps to improve the water quality. At the same time, the injection of gas and the circulation of water work together to accelerate the decomposition and removal of harmful substances in the water body, further enhancing the ecological restoration effect of the water environment.

[0028] The aeration unit achieves efficient mixing and aeration of gas and water, significantly increasing the dissolved oxygen content in the water. Utilizing the principle of pressure differential, the water circulates naturally, eliminating the need for additional power equipment and reducing operating costs. While restoring the water environment, the device prevents secondary pollution and helps restore the balance of aquatic ecosystems. The device has a wide range of applications and is suitable for various water environment restoration projects, including offshore areas, lakes, rivers, and ponds.

[0029] The aeration device can be used in a water environment repair system based on a water electrolysis hydrogen production platform. Since the floating platform 100 causes the water body near the floating platform 100, or part of the water body below the floating platform 100 to flow too slowly, this part of the water body forms a water environment to be repaired, and the aeration device can achieve the repair of this water environment.

[0030] Specifically, the floating platform 100 serves as the support base of the entire system, providing a stable platform for installing and fixing other equipment. The floating platform 100 utilizes the buoyancy of water to maintain its stability on the water surface and can adapt to different water depths and wave conditions.

[0031] The design of the diversion pipe can ensure that the water in the dead water area can be smoothly sucked into the manifold 3, thereby improving the water body repair effect of the water environment repair system based on the water electrolysis hydrogen production platform.

[0032] The flow guide tube can be configured as a rigid tube or a flexible tube.

[0033] Specifically, the platform can be a shallow-water wind power generation and water electrolysis hydrogen production platform. Shallow water has poor fluidity and severe eutrophication. Existing non-powered marine environmental remediation technologies are ineffective and slow to show results. In many shallow-water areas, poor water exchange leads to poor fluidity and reduced oxygen content in the seawater. This makes it difficult to effectively dilute and transfer pollutants and nutrients in the water, creating local environmental pressure. This insufficient hydrodynamic environment, especially in shallow waters less affected by tides and wind and waves, is more prone to accumulation, leading to deterioration of water quality.

[0034] The foundations of shallow-water wind turbines interfere with the flow of seawater and can easily form dead zones, necessitating greater attention to the seawater environment near wind turbine foundations. First, the foundation structures of wind turbines, such as pile foundations and gravity foundations, often significantly impact the flow of ocean water. These infrastructures create physical obstacles underwater, potentially altering the original flow path and causing a decrease in water mixing. Reduced mobility impedes water exchange in certain areas, creating "dead zones"—areas with slow water flow and reduced dissolved oxygen levels. These dead zones not only affect the habitats of marine life but can also lead to localized deterioration of water quality.

[0035] Secondly, the formation of dead zones is often accompanied by the intensification of eutrophication. In areas with poor mobility, nutrients easily accumulate, leading to the development of eutrophication. Algae in these conditions rapidly reproduce, forming algal blooms. This in turn reduces dissolved oxygen, impacting the survival and growth of fish and other marine life. The death and decomposition of algal blooms further depletes oxygen in the water, creating a vicious cycle that exacerbates the imbalance of the ecosystem.

[0036] The application of this water environment remediation system based on the water electrolysis hydrogen production platform can greatly improve the above-mentioned stagnant water problem.

[0037] The water electrolysis device and floating platform 100 form an integrated system. The water electrolysis process generates hydrogen and oxygen. The oxygen outlet provides a gas source for the aeration device, enabling gas recycling within the system and improving water activation.

[0038] After the water body is activated, it produces an oxidation effect on some metal ions in the water, which helps to reduce the concentration of metal ions and suspended matter in the water; if the water environment remediation system based on the electrolysis water hydrogen production platform is set on seawater, and the seawater needs to be activated before electrolysis, the seawater after oxidation will be beneficial to seawater desalination because the concentration of metal ions and suspended matter in the water is reduced.

[0039] The hydrogen and oxygen produced during water electrolysis are both clean energy sources. The oxygen is used for water aeration and activation, while the hydrogen can be further utilized or stored. The entire system forms a closed-loop ecosystem. In this system, the oxygen generated by water electrolysis is used for water aeration and activation, and the aerated and activated water helps improve the efficiency of the electrolysis system. This recycling approach helps promote the recovery and diversity of aquatic ecosystems.

[0040] Example 2:

[0041] Reference Figure 1-Figure 3 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0042] The aeration unit also includes a junction box 4, the interior of which forms a second inner cavity, which is connected to the lower end of the gas-liquid mixing pipeline 2 and the junction pipe 3; the junction box 4 can be used to support the gas-liquid mixing pipeline 2, and the gas-liquid mixing pipeline 2 can be provided in multiple numbers; the junction box 4 can be supported on the open end of the outer shell 1, and the outer shell 1 forms a buoy relative to the junction pipe 3, and a medium exchange port is formed between the junction box 4 and the outer shell 1.

[0043] In this embodiment, the junction box 4 not only forms a second inner cavity for conducting the medium, but also supports the gas-liquid mixing pipeline 2. When multiple gas-liquid mixing pipelines 2 are provided, the junction box 4 can provide a stable support structure to ensure stable operation of the entire aeration unit.

[0044] The second inner cavity serves as a collection and distribution device for the liquid output by the manifold 3 , and can evenly distribute the liquid to the gas-liquid mixing pipeline 2 , thereby improving the aeration effect of the liquid.

[0045] When the flow rate of the mixed medium in the gas-liquid mixing pipeline 2 is too high, exceeding the carrying capacity of the gas outlet, the excess medium can be discharged through the medium exchange port, providing an opening for overpressure relief. At the same time, the pipeline for inputting gas to the manifold 3 can also extend into the outline of the housing 1 at the medium exchange port and connect to the gas-liquid mixing pipeline 2. The medium exchange port also serves as an observation window, further improving the assembly and maintenance convenience of the device.

[0046] When there are multiple gas-liquid mixing pipelines 2, each gas-liquid mixing pipeline 2 can serve as an independent channel to mix gas and liquid and send them into different positions of the first inner cavity, thereby improving the aeration efficiency and making the entire aeration process more uniform and efficient.

[0047] Example 3:

[0048] Reference Figure 1-Figure 3 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further include the following technical solutions:

[0049] A plurality of aeration units are distributed at intervals laterally; the aeration device further includes an aeration pipe 5, which extends laterally. The aeration units distributed laterally at intervals are all supported on the aeration pipe 5, and the air outlets are all connected to the aeration pipe 5; a plurality of aeration ports are opened on the aeration pipe 5 to form a laterally extending aeration zone 10 in the water area above the aeration pipe 5.

[0050] In this embodiment, by distributing the aeration units laterally, aeration treatment can be performed simultaneously over a wider area. This distribution not only improves efficiency but also ensures that the entire water environment receives aeration activation evenly, avoiding the problem of over- or under-treatment in some areas.

[0051] As a laterally extending structure, the aeration pipe 5 not only provides stable support for the laterally spaced aeration units, but also communicates with the air outlets of the aeration units through the air outlets thereon, thereby achieving smooth transmission of gas and liquid.

[0052] The multiple aeration ports on the aeration pipe 5 allow the mixed medium output from the aeration unit to be evenly distributed throughout the water area above the aeration pipe 5. These aeration ports form a transversely extending aeration zone 10 above the aeration pipe 5, further expanding the range of aeration activation.

[0053] When the water in the aeration zone 10 is activated by aeration, its physical properties such as density and temperature will also change, thereby driving the water to form a more complex flow pattern around the aeration pipe 5, which helps to further improve the water quality and ecological environment.

[0054] Example 4:

[0055] Reference Figure 1-Figure 3 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further include the following technical solutions:

[0056] The aeration device further includes a plurality of valves 6 , which are connected between each gas outlet and the aeration pipe 5 to disconnect or open the passage from the corresponding first inner cavity to the aeration pipe 5 .

[0057] In this embodiment, by opening or closing the valve 6 , the flow rate of the medium entering the aeration pipe 5 can be adjusted according to actual needs, thereby adjusting the aeration intensity of the aeration zone 10 .

[0058] Or when a certain aeration unit needs to be maintained or replaced, the unit can be isolated by closing the corresponding valve 6 to avoid affecting the entire system. At the same time, it is also convenient to perform segmented maintenance or cleaning of the system when necessary.

[0059] The buoyancy of the corresponding aeration unit can also be increased by closing the valve 6 but still inputting gas into the gas-liquid mixing pipeline 2, thereby enabling the aeration unit to be used as a buoyancy unit, thereby enriching the function of the aeration unit.

[0060] Example 5:

[0061] Reference Figure 1-Figure 3 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further include the following technical solutions:

[0062] A plurality of aeration devices are provided and connected to the periphery of the floating platform 100 so that the aeration zone 10 surrounds or partially surrounds the floating platform 100 , thereby forming a bubble breakwater in the aeration zone 10 .

[0063] In this embodiment, the floating platform 100 is located in the center, providing a stable platform for the entire system. Multiple devices are evenly distributed around the floating platform 100. Through the aeration ports on the aeration pipes 5, a continuous aeration zone 10 is formed around the floating platform 100. These aeration zones 10 are interconnected, forming an aeration barrier surrounding the floating platform 100.

[0064] The aeration area 10 forms a dense bubble layer on the periphery of the floating platform 100 . These bubbles consume a certain amount of energy and generate a certain amount of resistance during the rising process, thereby alleviating the impact of external waves on the floating platform 100 .

[0065] That is, this embodiment not only achieves ecological restoration of the water environment, but also gives the system the function of a breakwater, thereby improving the stability and safety of the floating platform 100.

[0066] Through the coordinated operation of multiple aeration devices, a continuous aeration zone 10 is formed, which improves the efficiency and coverage of aeration activation and also improves the wave-breaking effect.

[0067] Example 6:

[0068] Reference Figure 1-Figure 3 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further include the following technical solutions:

[0069] The inner cavity and the first inner cavity of the floating platform 100 both form air chambers that can be inflated or deflated, so that the water environment remediation system based on the water electrolysis hydrogen production platform forms a dual buoyancy platform.

[0070] The dual buoyancy design of the inner cavity of the floating platform 100 and the first inner cavity makes the entire system more stable and reliable. Even if one air chamber fails or leaks, the other air chamber can still provide sufficient buoyancy to support the platform to float stably on the water surface.

[0071] The inner cavity of the floating platform 100 and the first inner cavity in the aeration device are designed as air chambers that can be inflated or deflated, which enables the water environment remediation system based on the water electrolysis hydrogen production platform to have the characteristics of a dual buoyancy platform.

[0072] The air chambers within the floating platform 100 can be inflated to increase buoyancy, allowing the platform to float stably on the water. Furthermore, when the platform's height needs to be adjusted or to accommodate varying water depths, the air can be deflated to reduce buoyancy, allowing the platform to rise or fall or adapt to varying water levels, maintaining a stable buoyancy.

[0073] The first inner cavity is also designed as an inflatable or deflated air chamber. This not only reduces the size of the aeration tube 5 to provide additional support and improves its stability during operation, but also can adjust the lifting of the water platform by adjusting the amount of gas in the air chamber.

[0074] By independently controlling the amount of gas in each chamber, the overall buoyancy of the system and the local aeration effect can be finely adjusted. This flexibility allows the system to adapt to different water environments and changes in restoration needs.

[0075] Example 7:

[0076] Reference Figure 1-Figure 3 In addition to all the technical solutions of any of the above embodiments, the embodiments of the present invention further include the following technical solutions:

[0077] The water environment remediation system based on the water electrolysis hydrogen production platform can switch between anchored and mobile states;

[0078] The air volume of the second inner chamber corresponding to the anchored state is less than that corresponding to the mobile state, so that the aeration unit's own gravity is greater than its own buoyancy, forming an anchoring component. The floating platform 100 and the aeration device are movably connected via a connecting assembly; the connecting assembly includes one or a combination of steel chains and cables.

[0079] In this embodiment, the water environment remediation system based on the water electrolysis hydrogen production platform has the ability to switch from a mobile state to an anchored state, which is used to stabilize the position of the platform and prevent it from drifting due to external factors such as water flow, wind and waves.

[0080] When the water environment remediation system based on the water electrolysis hydrogen production platform needs to be fixed in a specific location, anchoring can be achieved by reducing the amount of air in the second inner chamber. As the amount of air decreases, the gravity of the aeration unit becomes greater than its buoyancy, providing a downward force on the floating platform 100, allowing the aeration unit to form an anchoring component connected to the floating platform 100, thereby ensuring the stability of the floating platform.

[0081] The movable connection between the floating platform and the aeration device allows the platform to have a certain displacement when subjected to external forces such as wind, waves and water flow, which is conducive to ensuring its stability.

[0082] In summary, the water environment remediation system based on the electrolytic water hydrogen production platform switches between anchored and floating states by adjusting the air volume of the second inner chamber. The aeration unit acts as an anchor in the anchored state. The floating platform and aeration unit are flexibly connected by connecting components including steel chains to ensure system stability and reliability.

[0083] When the water environment remediation system based on the electrolytic water hydrogen production platform switches to the anchored state, along the distribution direction of the aeration unit, the amount of retained gas in the first inner cavity corresponding to the aeration unit close to the outside decreases toward the amount of retained gas in the first inner cavity corresponding to the aeration unit close to the inside, thereby forming an arch buoyancy model, just like Figure 3 shown.

[0084] When the water environment restoration system based on the electrolysis water hydrogen production platform is in an anchored state, its main purpose is to float stably on the water surface and carry out water environment ecological restoration work. In order to achieve this goal, the system will adjust the retained gas volume of each first inner cavity according to the distribution direction of the aeration unit. Specifically, the first inner cavity corresponding to the aeration unit close to the outside will be filled with more gas, while the first inner cavity corresponding to the aeration unit close to the inside will be filled with less gas. This decreasing distribution of retained gas volume helps to form an arched buoyancy model, making the platform more stable when floating and improving its ability to resist interference from external wind and waves.

[0085] When the water electrolysis hydrogen production platform's water environment remediation system needs to be moved, the first and second inner chambers can be inflated to their maximum capacity. This ensures the platform has sufficient buoyancy during movement to cope with potential challenges such as currents and waves. Furthermore, maximum inflation improves the platform's stability and safety, preventing accidents such as capsizing or sinking during movement.

[0086] The arched buoyancy pattern formed in the anchored state has several advantages:

[0087] The arched structure has high stability and can resist forces from all directions. Therefore, when the water environment remediation system based on the electrolytic water hydrogen production platform forms an arched buoyancy model, its stability on the water surface will be significantly improved.

[0088] By adjusting the amount of air retained in each first inner cavity to form an arched buoyancy model, the platform can be made more balanced when floating, which helps reduce the extra energy consumption and wear caused by platform shaking or tilting.

[0089] The water environment remediation system based on the water electrolysis hydrogen production platform can also be switched to a balanced adjustment state so that the inflation volume of the aeration unit matches the center of gravity adjustment requirements of the water environment remediation system based on the water electrolysis hydrogen production platform, thereby ensuring the overall stability of the platform.
