Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power hydrogen production and energy storage, and particularly relates to an integrated wind-hydrogen-energy storage offshore platform. Background Art

[0002] The broad development prospects of offshore wind power play a crucial role in promoting the transformation of the energy structure. However, with the rapid increase in the installed capacity of wind power, problems in the development of wind power have gradually emerged. For example, the uncontrollability of wind energy itself leads to significant volatility in wind power generation.

[0003] Specifically, the phenomenon of abandoning wind and electricity occurs during overproduction, resulting in a waste of wind energy resources; it brings great difficulties to power grid dispatching during underproduction. At the same time, for offshore wind power platforms, the operation and maintenance difficulty and power loss are positively correlated with the offshore distance, and they also face multiple challenges such as cable routing planning, cable landing site selection, and marine space use restrictions. Therefore, in order to enable offshore wind power platforms to better utilize offshore wind energy resources, store wind energy during overproduction, and then convert the stored energy into electricity during underproduction, and grid-connect and generate electricity when the wind power generation power of the wind farm is low or unstable.

[0004] Traditional energy storage methods mainly use chemical energy storage methods. However, it is difficult to meet the growing needs of offshore wind power platforms due to its limited capacity and high maintenance costs. In contrast, the wind power hydrogen production energy storage technology stands out with its advantages such as high capacity, easy transportation, environmental protection and no pollution, and has become a potential energy storage solution in the field of offshore wind power. However, in traditional wind power hydrogen production energy storage technologies, a simple stacked layout is mostly used, and there is a lack of coupled layout between functional modules. For example, subsystems such as hydrogen production units (electrolyzers), purification devices, and compressor units are arranged separately, resulting in inefficient use of the platform space. Summary of the Invention

[0005] In view of this, the present invention provides an integrated wind-hydrogen-energy storage offshore platform to solve the problem that the traditional wind power hydrogen production energy storage technology uses a simple stacked layout, resulting in inefficient use of the platform space.

The water inlet of the water filtering device is communicated with the water outlet of the water lifting unit through a water inlet pipe, and the water outlet of the water filtering device transports the deionized water formed after filtration to the hydrogen production module through a water delivery pipe.

[0007] Beneficial effects: By arranging the water filtering device in the receiving chamber of the column below the sea surface, the space above the deck originally used for installing the water filtering device is vacated, reducing the space occupation of the deck, creating more installation space for modules such as hydrogen production and hydrogen storage, which helps to achieve space optimization. At the same time, the vacated space supports the expansion of hydrogen production and hydrogen storage equipment and can flexibly expand other functional modules to support the upgrade of the platform functions. In addition, by arranging the water filtering device in the receiving chamber, after the water lifting unit pumps seawater, it is directly transported to the water filtering device, so that the processes of seawater extraction and filtration can be completed in the receiving chamber, reducing the pipelines and cables above the platform, saving costs and reducing transportation risks, and further optimizing the layout.

[0011] In an alternative embodiment, the utility module further includes a heat exchange device arranged in the accommodation chamber. The water inlet of the heat exchange device is communicated with the water outlet of the water filtration device through a heat exchange water inlet pipe fitting, and the water outlet of the heat exchange device transports the deionized water obtained by filtration to the hydrogen production module, the hydrogen storage module, and the utility module through a heat exchange water outlet pipe fitting and a circulation pipe fitting.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Figure 1 It shows the front view of the integrated wind-hydrogen-storage offshore platform provided by the present invention; Figure 2 It shows the top view of the hydrogen production module of the integrated wind-hydrogen-storage offshore platform provided by the present invention after being separated from the deck;Figure 3 The side view of the integrated wind-hydrogen energy storage offshore platform provided by the present invention is shown.

[0034] Next, in conjunction with Figures 1 to 3 , embodiments of the present invention will be described.

[0035] According to an embodiment of the present invention, an integrated wind-hydrogen energy storage offshore platform is provided. The offshore platform includes a platform main body 1, a deck 2, a hydrogen production module 3, a hydrogen storage module 4, and a utility module 5.

[0036] Among them, the hydrogen production module 3, the hydrogen storage module 4, and the control module 8 are all electrically connected to the utility module 5; the hydrogen production module 3 is connected to the hydrogen storage module 4 through a pipeline.

[0037] In use, the utility module 5 is used to extract seawater and desalinate and purify it to form deionized water for the hydrogen production module 3 to produce hydrogen by electrolyzing the deionized water.

[0038] At the same time, the deionized water can also be used as cooling water and flow through the hydrogen production module 3 and the hydrogen storage module 4 respectively through the circulating pipe fittings for heat exchange treatment. The processed hydrogen is transported through the pipeline from the hydrogen production module 3 to the hydrogen storage module 4 for storage.

[0039] Furthermore, the hydrogen in the hydrogen storage module 4 is transported by ship to the application terminal (such as a hydrogen energy ship), forming an off-grid offshore wind power hydrogen production and storage mode, realizing the function of an offshore hydrogen refueling station, omitting the cost of power transmission and the sea use approval procedures for cable routing, and reducing the waste of abandoned wind and electricity.

[0040] Specifically, as Figures 1 to 3 shown, the platform main body 1 includes several columns 11, and at least one cross beam 12 is connected between two adjacent columns 11. At least one column 11 is provided with an accommodation chamber below the sea surface; the deck 2 is arranged above the platform main body 1 and above the sea surface. The surface of the deck 2 is provided with a hydrogen production area 21 and a hydrogen storage area 22, and the hydrogen storage area 22 is adjacent to the hydrogen production area 21.

[0041] Among them, the hydrogen production module 3 is arranged in the hydrogen production area 21; the hydrogen storage module 4 is arranged in the hydrogen storage area 22, and the hydrogen storage module 4 is used to receive and store the hydrogen produced by the hydrogen production module 3; the utility module 5 includes a water lifting unit 51 and a water filtration device 52. The water lifting unit 51 is used to extract seawater, and the water filtration device 52 is installed in the accommodation chamber. The water inlet of the water filtration device 52 is communicated with the water outlet of the water lifting unit 51 through a water inlet pipe fitting, and the water outlet of the water filtration device 52 transports the filtered deionized water to the hydrogen production module 3 through a water delivery pipe fitting.

[0042] With such an arrangement, by disposing the water filtration device 52 in the accommodation chamber of the column 11 below the sea surface, the space above the deck 2 that was originally used for installing the water filtration device 52 is vacated, reducing the space occupied by the deck 2 and creating more installation space for modules such as hydrogen production and hydrogen storage, which helps to achieve space optimization.

[0043] Meanwhile, the vacated space supports the expansion of hydrogen production and hydrogen storage equipment and can flexibly expand other functional modules, supporting the upgrade of platform functions.

[0044] In addition, by setting the water filtration device 52 in the accommodation chamber, after the water lifting unit 51 extracts seawater, it is directly transported to the water filtration device 52, enabling the processes of seawater extraction and filtration to be completed within the accommodation chamber, reducing the pipelines and cables above the platform, saving costs and reducing transportation risks, and further optimizing the layout.

[0045] Furthermore, the water lifting unit 51 is connected to a water extraction pipe component, and the water extraction pipe component extends into the seawater.

[0046] It can be noted that the water lifting unit 51 is preferably a water pump, installed on the side wall of the column 11 close to another column 11 for extracting seawater from the ocean into the accommodation chamber.

[0047] It can be noted that the hydrogen production module 3 includes a hydrogen production chamber 31, and the hydrogen production chamber 31 is installed in the hydrogen production area 21. At this time, hydrogen production equipment 32 and hydrogen purification equipment 33 are installed inside the hydrogen production chamber 31.

[0048] Among them, both the hydrogen production equipment 32 and the hydrogen purification equipment 33 operate in a parallel manner with multiple devices. According to the actual power generation, the number of hydrogen production equipment 32 and hydrogen purification equipment 33 is turned on as needed, reducing the loss of equipment idling operation.

[0049] Furthermore, both the hydrogen production equipment 32 and the hydrogen purification equipment 33 adopt a containerized structure, which is convenient for hoisting, installation combination, and disassembly and maintenance.

[0050] During use, the hydrogen prepared by the hydrogen production equipment 32 is transported to the hydrogen purification equipment 33 through a pipeline for removing hydrogen impurities. The hydrogen purification equipment 33 is arranged adjacent to the hydrogen production equipment 32, which can reduce the routing distance of the pipeline and reduce the pipeline laying cost.

[0051] In one embodiment, as Figure 2 and Figure 3As shown, several columns 11 at least include a first column 111, a second column 112, and a third column 113; the integrated wind-hydrogen-storage offshore platform further includes a wind power module 6, including a tower barrel 61 and a wind turbine 62. The tower barrel 61 is installed above one of the first column 111, the second column 112, and the third column 113, and the wind turbine 62 is installed above the tower barrel 61; the deck 2 is arranged above the other two of the first column 111, the second column 112, and the third column 113.

[0052] With such an arrangement, a traditional offshore platform usually uses a central deck 2 to connect all columns 11. In this solution, by centrally installing the tower barrel 61 and the wind turbine 62 on one column 11 and arranging the deck 2 only above the other two columns 11, the complex structure of the central deck 2 is eliminated, directly reducing the steel consumption.

[0053] At the same time, the wind power module 6 (tower barrel 61 + wind turbine 62) acts on one column 11, while the deck 2 and equipment such as hydrogen production and hydrogen storage act on the other two columns 11, which helps to form a balanced weight distribution, improve the phenomenon of center of gravity offset, and significantly enhance the anti-overturning ability of the platform in complex marine environments such as wind waves and ocean currents.

[0054] During use, the wind power module 6 is connected to the utility module 5 through a cable, converts wind energy into electrical energy, and provides the required electrical energy for each module through the utility module 5.

[0055] Preferably, the wind turbine 62 is selected as a three-blade structure, and the tower barrel 61 is selected as a steel pipe structure.

[0056] During installation, the cable at the wind turbine 62 is located inside the tower barrel 61 and extends to the utility module 5.

[0057] It can be illustrated that the hydrogen storage module 4 includes a hydrogen compression device 41 and a hydrogen storage device 42. At this time, the hydrogen decompression device is arranged adjacent to the low-pressure hydrogen storage device and is connected to it through a pipeline; the hydrogen compression device 41 is connected to the hydrogen purification device 33 through a pipeline.

[0058] During use, the hydrogen purified by the hydrogen purification device 33 enters the hydrogen compression device 41 through a pipeline. After the hydrogen compression device 41 compresses the hydrogen to the specified pressure level, the compressed hydrogen is transported to the hydrogen storage device through a pipeline.

[0059] In one embodiment, as Figure 2 shown, there are two groups of hydrogen storage areas 22, which are respectively arranged close to the other two of the first column 111, the second column 112, and the third column 113; the hydrogen production area 21 is arranged between the two groups of hydrogen storage areas 22.

[0060] With such an arrangement, by disposing the two hydrogen storage areas 22 close to the other two of the first column 111, the second column 112, and the third column 113 respectively, at this time, since the hydrogen production area 21 is disposed between the two hydrogen storage areas 22, it helps the two hydrogen storage areas 22 to be symmetrically arranged, making the overall weight distribution of the platform more uniform, reducing the risk of the center of gravity shifting in a single direction, reducing the difficulty of ballast water leveling, and improving the anti-overturning ability of the platform in a complex marine environment.

[0061] Wherein, a set of hydrogen storage modules 4 is provided in each hydrogen storage area 22, and the two sets of hydrogen storage modules 4 are symmetrically distributed.

[0062] Wherein, accommodation chambers are provided inside the second column 112 and the third column 113. At this time, a water filtering device 52 and a heat exchange device 53 are provided inside each accommodation chamber, and two water lifting units 51 are correspondingly provided.

[0063] In one embodiment, as Figure 3 shown, the crossbeam 12 at least includes a top crossbeam and a bottom crossbeam, and the bottom crossbeam is located below the top crossbeam; the integrated wind-hydrogen-storage offshore platform further includes an external interface module 7, including a mechanical interface 71 and an electrical interface 72. The mechanical interface 71 is detachably installed on the bottom crossbeam for externally connecting a cable, and the electrical interface 72 is detachably installed on the top crossbeam. The electrical interface 72 is electrically connected to the mechanical interface 71 and is electrically connected to the electrical appliances at the offshore platform.

[0064] With such an arrangement, by providing the mechanical interface 71 and the electrical interface 72 and detachably installing the mechanical interface 71 and the electrical interface 72 on the bottom crossbeam and the top crossbeam respectively, the platform can not only produce and store hydrogen off-grid, but also externally connect a dynamic cable to conduct grid connection with a wind farm, enabling the platform to quickly switch its own mode according to the requirements of different scenarios and enhancing the flexibility of platform operation.

[0065] Specifically, when the platform is not connected to the power grid, the wind energy is converted into hydrogen by its own hydrogen production module 3 for storage without relying on an external power grid; by externally connecting a dynamic cable through the mechanical interface 71, the platform is connected to a seawater wind farm or the power grid, and the electric energy of the seawater wind farm or the power grid supplies power to this platform, that is, to ensure that the equipment in the hydrogen production module 3, the hydrogen storage module 4, the utility engineering module 5, and the control module 8 can operate normally.

[0066] In addition, the mechanical interface 71 provided at the bottom can adapt to the long-distance and highly flexible dynamic cables in the deep and far sea scenarios to support the electrical connection between the platform and the offshore power grid or the seawater wind farm, while the electrical interface 72 provided at the top, due to being located on the top crossbeam and close to the deck 2, can reduce the impact of seawater on it, thereby extending its service life.

[0067] Among them, "dynamic" means that the mechanical interface 71 and the electrical interface 72 can be disassembled and disassembled and installed on the cross beam 12 as required.

[0068] Furthermore, the electrical interface 72 is pre-sealed and waterproofed and is above the sea surface after installation.

[0069] In one embodiment, as Figure 3 shown, the utility module 5 further includes a heat exchange device 53 arranged in the accommodation chamber, and the water inlet of the heat exchange device 53 is communicated with the water outlet of the water filtration device 52 through a heat exchange water inlet pipe fitting, and the water outlet of the heat exchange device 53 transports the deionized water obtained by filtration to the hydrogen production module 3, the hydrogen storage module 4 and the utility module 5 through a heat exchange water outlet pipe fitting and a circulation pipe fitting.

[0070] With such an arrangement, by using the heat exchange water inlet pipe fitting, the deionized water obtained by filtering the water filtration device 52 is transported into the heat exchange device 53, and by using the heat exchange water outlet pipe fitting and the circulation pipe fitting, the deionized water is used as a cooling medium to absorb the heat generated during the operation of the hydrogen production module 3, the hydrogen storage module 4 and the utility module 5, maintain the hydrogen production efficiency, reduce potential safety hazards, and achieve reuse, reduce water resource consumption, and achieve the purpose of efficient resource utilization.

[0071] In addition, by arranging the heat exchange device 53 and the water filtration device 52 in the accommodation chamber, the corrosion of the equipment caused by high temperature, high humidity and high salt in the ocean can be reduced, the stability of the equipment can be improved, and the maintenance cost can be reduced.

[0072] In one embodiment, as Figure 1 and Figure 2 shown, a utility area 23 is also provided on the surface of the deck 2, and the utility area 23 is communicated with the hydrogen storage area 22; the utility module 5 further includes an electrical equipment 54 and a water supply equipment 55, and the electrical equipment 54 is arranged in the utility area 23; the water supply equipment 55 is arranged in the utility area 23.

[0073] With such an arrangement, by communicating the utility area 23 with the hydrogen storage area 22 and centrally arranging the electrical equipment 54 and the water supply equipment 55, the space utilization rate of the deck 2 is maximized and the redundant area is reduced.

[0074] Specifically, the electrical equipment 54 is centrally powered, shortening the power distribution path and reducing the line loss. The water supply equipment 55 is communicated with the hydrogen storage area 22, facilitating the provision of a stable water source for the hydrogen production process, reducing the laying requirement of long-distance water conveyance pipelines, realizing space integration, and reducing the platform construction and operation and maintenance costs.

[0075] Among them, the electrical equipment 54 includes a variable voltage and rectification cabinet electrically connected to the fan 62. At this time, the variable voltage and rectification cabinet is electrically connected to the fan 62 through a cable, and the cable is located inside the tower barrel 61 and is used to connect the electric energy generated by the fan 62 to the variable voltage and rectification cabinet and adjust it.

[0076] Further, the electrical equipment 54 further includes power station equipment electrically connected to the transformer-rectifier cabinet, and the power station equipment supplies power to the hydrogen production module 3, the hydrogen storage module 4, the control module 8, the water lifting unit 51, the water filtering equipment 52, the heat exchange equipment 53, and the water supply equipment 55 respectively.

[0077] Further, the electrical equipment 54 further includes a switch cabinet, which is used to control the disconnection or connection of the circuit to protect the circuits where each electrical appliance is located, such as overload protection, short-circuit protection, leakage protection, under-voltage and over-voltage protection.

[0078] It should be noted that the water supply equipment 55 is located directly above the water lifting unit 51, reducing the routing distance of the pipeline.

[0079] Preferably, the number of the common areas 23 is two, which are respectively arranged adjacent to the two hydrogen storage areas 22.

[0080] It can be explained that according to actual needs, the number of layers of the deck 2 is increased as required, and the hydrogen production module 3 and the hydrogen storage module 4 are arranged on the increased deck 2 as required. The specific increased quantity is determined according to the actual working conditions.

[0081] In one embodiment, the integrated wind-hydrogen-storage offshore platform further includes a control module 8, which includes a fire-fighting equipment 81. The water inlet of the fire-fighting equipment 81 is communicated with the water outlet of the water filtering equipment 52 through a fire-fighting pipe fitting.

[0082] With such a setting, by communicating the water inlet of the fire-fighting equipment 81 with the water outlet of the water filtering equipment 52 through a fire-fighting pipe fitting, the water treated by the water filtering equipment 52 is used for fire-fighting, reducing the risk of blockage of the sprinkler system and stably providing a fire-fighting water source. At the same time, the water filtering equipment 52 serves both hydrogen production and fire-fighting, realizing the multi-purpose use of water and reducing resource waste.

[0083] Preferably, the fire-fighting equipment 81 is arranged in the common area 23.

[0084] It can be explained that the control module 8 further includes a control device 82, which is used to control the start-up and shutdown of each electrical appliance, conduct power transmission control and protection on each electrical appliance, and monitor and adjust the parameters of each power transmission line in real time to ensure the stable operation of the power system of the offshore platform.

[0085] Among them, there are two groups of both the control device 82 and the fire-fighting equipment 81. The two groups of control devices 82 are respectively arranged on both sides of the hydrogen production chamber 31, and the two groups of control devices 82 are symmetrically distributed; the two groups of fire-fighting equipment 81 are respectively arranged in the two common areas 23, and the two groups of fire-fighting equipment 81 are symmetrically distributed.

[0086] Furthermore, the control module 8 also includes a separation device 83 and an energy storage device 84 . In this case, the separation device 83 and the energy storage device 84 are arranged on the top of the hydrogen production chamber 31 .

[0087] Preferably, the separation device 83 is a gas-water separation device, which is used to remove water from the hydrogen to prevent the water from having a negative impact on subsequent storage, transportation, fuel cells and other links.

[0088] Preferably, the energy storage device 84 is a battery, which is used to store electrical energy.

[0089] When the utility module 5 fails or fails to provide power due to the randomness and intermittency of the fan 62, the energy storage device 84 acts as an emergency energy supply device to provide power to the electrical appliances on the platform. At the same time, it can also ensure that the cooling medium continues to flow to avoid overheating of the hydrogen production module 3 and the hydrogen storage module 4.

[0090] In one embodiment, the column 11 is provided with a ballast water tank, and the ballast water tank is provided with a water exchange port, and the ballast water tank is injected with seawater or discharged with seawater through the water exchange port.

[0091] With such arrangement, since the ballast water tank is located inside the column 11, seawater can be quickly injected or discharged through the water exchange port to accurately adjust the center of gravity of the platform to adapt to the center of gravity shift caused by wind, waves or load changes, ensuring that the overall center of gravity will not shift significantly.

[0092] For example, when the hydrogen storage module 4 is fully loaded or unloaded, the effect of the weight change on the balance of the platform can be offset by adjusting the amount of water in the ballast water tank of the column 11.

[0093] It helps to quickly adjust the amount of ballast water in severe sea conditions (such as strong winds and waves) to reduce the platform's heel and pitch and improve its anti-capsulation ability.

[0094] In one embodiment, Figure 1 and Figure 3 As shown, the wind-hydrogen storage integrated offshore platform also includes a mooring 9, one end of the mooring 9 is connected to the column 11 along its length direction, and the other end is connected to the seabed.

[0095] In this way, by setting up a mooring 9 and using it to connect the seabed with the column 11, a strong anchor is provided for the platform, which significantly improves its stability in a complex deep-sea environment, can withstand the combined loads of strong winds, huge waves, ocean currents, etc. in the deep-sea, reduce the platform's roll and pitch amplitude, reduce the impact of the platform's shaking on the hydrogen production equipment 32 (such as the electrolyzer) and the hydrogen storage tank, and reduce the risk of equipment failure and hydrogen leakage due to vibration.

[0096] Preferably, each column 11 is provided with a mooring 9 .

[0097] In one embodiment, the integrated offshore platform for wind-hydrogen energy storage further includes an explosion-proof wall 10, which is arranged between the hydrogen production area 21 and the hydrogen storage area 22.

[0098] With such an arrangement, by providing the explosion-proof wall 10, physical isolation is provided to block high-temperature debris generated by an explosion and prevent the spread of flames, significantly reducing the risk of damage to adjacent areas caused by accidental explosions in the hydrogen production area 21 and the hydrogen storage area 22, avoiding synchronous damage to other functional modules, and avoiding the overall shutdown of the wind turbine 62 due to equipment failures.

[0099] Preferably, two explosion-proof walls 10 are provided, which are respectively arranged at the connections between the hydrogen production area 21 and the two hydrogen storage areas 22.

[0100] In the integrated offshore platform for wind-hydrogen energy storage provided in the above embodiment, during use, the water-lifting unit 51 pumps seawater and transports the pumped seawater to the water filtration device 52 for filtration to remove impurities, forming deionized water.

[0101] Among them, a part of the deionized water flows through the hydrogen production module 3, the hydrogen storage module 4, and the utility module 5 as a cooling medium, and realizes internal circulation through the circulation pipe fittings and the circulation water pump, and heat exchange is completed during the circulation process.

[0102] The remaining deionized water is partly transported to the hydrogen production module 3 to produce hydrogen, and the other part of the deionized water is transported to the fire-fighting equipment 81 for storage, and is sprayed through the spray pipe fittings on subsequent high-temperature areas and the ignition points.

[0103] In the integrated offshore platform for wind-hydrogen energy storage provided in the above embodiment, the hydrogen production module 3, the hydrogen storage module 4, the utility module 5, the control module 8, and the external interface module 7 are integrally arranged on the platform body to form a floating integrated offshore platform for wind-hydrogen energy storage.

[0104] Among them, by placing the tower barrel 61 and the wind turbine 62 on one of the columns 11, the deck 2 and related equipment are arranged on the other two columns 11, and then through the symmetrical layout of the two groups of hydrogen storage areas 22, the symmetrical distribution of the two groups of hydrogen storage modules 4, the symmetrical distribution of the two groups of control devices 82, and the symmetrical distribution of the two groups of fire-fighting equipment 81, a symmetrical platform layout structure is realized.

[0105] With such an arrangement, the weights borne by each column are relatively balanced, effectively reducing the offset of the overall center of gravity relative to the geometric center, reducing the difficulty of leveling the overall platform by the ballast water, realizing a centralized layout method, improving the space utilization rate, and enabling independent construction, installation, upgrade and transformation, as well as operation and maintenance of each module, reducing the use lengths of pipelines and cables, reducing the operating cost, and facilitating the maintenance personnel to board the ship to repair equipment during the operation and maintenance period.

[0106] Meanwhile, since there is a gap between the tower barrel 61 of the fan 62 and the hydrogen production module 3 and the hydrogen storage module 4, the risk of interference is reduced.

[0107] In addition, by eliminating the design of the central deck 2, the overall steel consumption can be reduced, thus saving costs.

[0108] Furthermore, by using the external interface module 7, off-grid hydrogen production and storage, and grid connection with a wind farm or the power grid can be achieved, which is applicable to a variety of scenarios, reducing the impact of factors such as sea area conditions, safety distances, power transmission routes, and cable landing sites on the platform.

[0109] Moreover, by using the explosion-proof wall 10, the damage caused by accidental explosions can be reduced. When the fan 62 stops rotating and wind energy is no longer used for power generation, it ensures the safe shutdown of each device in case of emergency.

[0110] In addition, on the one hand, the present invention can be used as a development platform for ocean wind energy resources, and on the other hand, it can be used as an offshore hydrogen refueling station for hydrogen energy ships. Arranging the present invention on an ocean shipping lane or an ocean mining area can be used as an offshore energy supply station, outputting continuous and stable hydrogen energy to meet the power supply needs of ships in the shipping lane and the energy supply needs of mining ships, and can better serve large-scale ocean energy development.

[0111] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
