Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to a marine integrated platform suitable for multi-format development and an installation method thereof. Background Art

[0002] As the most vast and rich treasure trove of renewable energy on earth, the ocean's development potential and value have increasingly attracted widespread attention from the international community. Traditional marine energy development methods, such as offshore wind power and offshore photovoltaics, have alleviated the problem of tight energy supply to a certain extent and opened up new paths for the development of clean energy. However, these single-format development models have gradually exposed limitations such as waste of space resources, interference with the ecosystem, and difficulty in technical integration. Although offshore wind power technology has made significant progress, the construction and operation of wind farms have inevitably had a certain impact on the marine ecosystem. At the same time, the intermittent and uncertain nature of wind energy has brought challenges to the stable operation of the power system. Offshore photovoltaics face severe tests of the complexity of the marine environment. Harsh conditions such as high salinity, strong corrosion, and large waves have put forward extremely high requirements on the durability and reliability of photovoltaic modules. In addition, the high cost of operation and maintenance has limited its large-scale application. At the same time, traditional marine fisheries face bottlenecks such as limited aquaculture space, frequent diseases, and low aquaculture efficiency. In addition, the intensification of marine environmental pollution and ecological damage has made the sustainable utilization of marine fishery resources face severe challenges.

[0003] In this context, the development of an offshore wind, solar, fishery, hydrogen and wave multi-industry integrated platform has become an important way to solve the above problems and achieve a win-win situation for efficient utilization of marine resources and environmental protection. However, the coexistence of fishery and energy industries in space has also brought about complex technical problems, such as how to avoid interference of fishery activities with wind power and photovoltaic equipment, and how to ensure fishery production without affecting the safe operation of energy facilities. Summary of the invention

[0004] In view of the problem in the prior art of how to ensure fishery production without affecting the safe operation of energy facilities, the present invention provides a marine integrated platform suitable for multi-format development, with a wave energy device on the top, aquaculture cages on the bottom, and a suction cylinder anchoring system on the bottom, which can ensure the safe operation of energy facilities while ensuring fishery production.

[0005] In order to achieve the above object, the present invention provides the following technical solutions.

[0006] In the first aspect, the present invention provides an integrated marine platform suitable for multi-format development, including a wind turbine, a main frame, a wave energy device, a suction cylinder anchoring system, aquaculture cages, photovoltaic modules, a multifunctional platform and a hydrogen production and storage device; the multifunctional platform is arranged above the main frame; the wind turbine is located on the multifunctional platform and is fixedly connected to the main frame; the hydrogen production and storage device is arranged on the multifunctional platform; the wave energy device is arranged in the side area of ​​the main frame; the suction cylinder anchoring system is arranged in the bottom area of ​​the main frame; the aquaculture cage is arranged inside the main frame.

[0007] As a further improvement of the present invention, the horizontal height of the wave energy device is flush with the aquaculture cage.

[0008] As a further improvement of the present invention, the wind turbine generator set is arranged on the multifunctional platform and is located in the top corner area of ​​the main frame.

[0009] As a further improvement of the present invention, a living area module and a storage compartment are also provided on the multifunctional platform; the living area module is arranged on a side close to the wind turbine generator set, and the storage compartment is arranged on the other side of the living area module.

[0010] As a further improvement of the present invention, the hydrogen production and storage device is arranged on the other side of the wind turbine generator set; a crane is arranged on the side of the hydrogen production and storage device facing the central area of ​​the multi-functional platform; the hydrogen production and storage device includes the hydrogen storage tank body and the hydrogen production module.

[0011] As a further improvement of the present invention, the photovoltaic components are arranged at the edge area of ​​the multifunctional platform.

[0012] As a further improvement of the present invention, the multifunctional platform is fixed on the main frame via a platform supporting structure.

[0013] As a further improvement of the present invention, the horizontal height of the wave energy device is flush with the aquaculture cage.

[0014] As a further improvement of the present invention, the main frame is a four-sided frame type.

[0015] In a second aspect, the present invention provides a method for installing an integrated marine platform suitable for multi-format development, comprising: Place the main frame into the set seabed area; The suction cylinder anchoring system is installed on the main frame, and the main frame is adsorbed on the seabed by the negative pressure generated by the suction cylinder anchoring system; Install a multifunctional platform above the main frame; install the wind turbine generator set, photovoltaic modules and hydrogen production and storage device on the multifunctional platform; Installing the wave energy device on the side area of ​​the main frame; The breeding cages are installed inside the main frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention not only realizes the efficient three-dimensional development and utilization of marine resources by integrating diversified functional modules such as wind turbines, main frames, wave energy devices, suction cylinder anchoring systems, aquaculture cages, photovoltaic modules, multifunctional platforms, and hydrogen production and storage devices, but also ensures the safe and reliable operation of energy facilities while ensuring the sustained and stable production of fisheries. First, the present invention effectively utilizes the abundant wind energy resources over the ocean by directly installing the wind turbines on the multifunctional platform and firmly connecting it to the main frame, providing a sustainable power supply for the platform. It not only reduces dependence on traditional fossil energy and reduces carbon emissions, but also reduces losses in the power transmission process and improves energy utilization efficiency by supplying power nearby. Secondly, the setting of the wave energy device further broadens the platform's energy acquisition channels. Using ocean waves, a natural energy source that is almost everywhere, the wave energy device can continuously and stably provide additional power support for the platform, enhancing the energy self-sufficiency of the entire system. This dual energy (wind energy + wave energy) complementary design strategy not only improves the stability and reliability of energy supply, but also makes the platform more adaptable and resilient when facing fluctuations in a single energy source, ensuring that energy facilities can operate safely under any conditions.

[0017] Furthermore, by building the aquaculture cages inside the main frame, not only can the water space under the platform be fully utilized to avoid direct conflict with energy facilities, but also a suitable growth environment for marine life can be provided. This three-dimensional aquaculture model not only improves the output efficiency per unit sea area, but also promotes the rational allocation of fishery resources and ecological balance by optimizing the aquaculture structure and variety selection.

[0018] Furthermore, by laying high-efficiency photovoltaic panels on the multi-functional platform or other suitable locations, it is possible to capture and utilize solar energy, increase the platform's energy self-sufficiency rate, and reduce dependence on external power grids. The combination of photovoltaic modules with wind turbines and wave energy devices can provide strong support for the long-term stable operation of the platform.

[0019] Furthermore, the installation of hydrogen production and storage devices is a positive response of the present invention to future energy transformation. By using the excess electricity generated on the platform through water electrolysis and other methods, hydrogen is produced and stored safely, which not only provides a clean and efficient energy reserve for the platform, BRIEF DESCRIPTION OF THE DRAWINGS The drawings described herein are for illustrative purposes only and are not intended to limit the scope of the present disclosure in any way.

[0023] In view of the problem in the prior art of how to ensure fishery production without affecting the safe operation of energy facilities, the present invention provides a marine integrated platform suitable for multi-format development, including: a wind turbine 1, a main frame 20, a wave energy device 5, a suction cylinder anchoring system, aquaculture cages 7, photovoltaic modules 8, a multifunctional platform 9 and a hydrogen production and storage device.

[0024] like Figure 1As shown, the aquaculture cage 7 is arranged inside the main frame 20, a multifunctional platform 9 is arranged on the upper part of the main frame 20, the wind turbine 1, the photovoltaic module 8 and the hydrogen production and storage device are all arranged on the multifunctional platform 9, and a wave energy device 5 is arranged in the side area of ​​the main frame 20, and the horizontal height of the wave energy device 5 is flush with the aquaculture cage 7. A suction cylinder anchoring system is arranged in the bottom area of ​​the main frame 20. The suction cylinder anchoring system includes a suction cylinder 6.

[0025] The suction cylinder 6 is deeply embedded in the seabed soil through the negative pressure principle, providing the platform with strong anti-roll, anti-pullout and anti-slip capabilities, and effectively resisting the impact of natural environmental factors such as ocean currents, wind and waves. This design not only simplifies the traditional anchor chain or pile foundation installation method, reduces the construction difficulty and cost, but also reduces the damage to the seabed ecology, achieving a win-win situation for environmental protection and economic benefits. At the same time, the stability of the suction cylinder provides a stable water environment for the aquaculture cages, ensuring the smooth progress of fishery production.

[0026] The multifunctional platform 9 is C-shaped. The wind turbine 1 is arranged on the multifunctional platform 9 and is located in the top corner area of ​​the main frame 20. The multifunctional platform 9 is also provided with a residential module 3 and a storage compartment 4. The residential module 3 is arranged near the wind turbine 1, and the storage compartment 4 is arranged near the residential module 3. The multifunctional platform 9 is also provided with a hydrogen production and storage device, which is located near the wind turbine 1, and a photovoltaic module 8 is arranged in the edge area of ​​the multifunctional platform 9.

[0027] The hydrogen production and storage device comprises a hydrogen storage tank 10 and a hydrogen production module 11 .

[0028] The hydrogen storage tank 10 and the hydrogen production module 11 are located in the edge area of ​​the multifunctional platform 9, and a crane 2 is arranged on the hydrogen storage tank 10 and the hydrogen production module 11 facing the center direction of the platform.

[0029] The overall marine integrated platform of the present application is a fixed structure, and the main frame 20 serves as the supporting structure of the platform, which is firmly set on the sea surface. The shape and size of the main frame 20 can be designed according to specific needs to ensure the stability and carrying capacity of the platform. Inside the main frame 20, aquaculture cages 7 are provided for marine aquaculture operations. The number and position of aquaculture cages 7 can be adjusted according to aquaculture needs to achieve the best aquaculture effect. The upper part of the platform is a wind turbine 1; the middle part is a multi-functional platform 9, which is used to place different types of energy or operation and maintenance equipment, including offshore photovoltaics, offshore hydrogen production, marine aquaculture and other equipment. A wave energy device 5 is installed above the middle outer frame, the lower part is aquaculture cages 7, and the bottom is a suction cylinder anchoring system, thus forming a wind, solar, fishery, hydrogen and wave fixed multi-format integrated platform.

[0030] like Figure 2As shown, a cage frame 71 is provided in the aquaculture cage 7 to reduce the impact of the aquaculture cage 7 in the seawater, and the multifunctional platform 9 is fixed to the main frame 20 through the platform support structure 21. A wave energy device 5 is provided in the side area of ​​the main frame 20. The device uses wave energy to generate electricity and provides additional energy supply for the platform. The horizontal height of the wave energy device 5 is flush with the aquaculture cage 7, which does not affect the aquaculture operation and can make full use of the wave energy resources. A suction cylinder 6 is provided in the bottom area of ​​the main frame 20 as the anchoring system of the platform. The suction cylinder 6 forms a negative pressure by sucking in seawater and discharging the air therein, thereby firmly fixing the platform to the seabed.

[0031] like Figure 3 As shown, the main frame 20 is a four-sided frame type, with main support columns at the four corners of the periphery, and the main support columns are composed of diagonal braces and horizontal braces to form a truss structure. The internal space of the lower truss structure is used to place the breeding cage 7, the breeding water body is not less than 50,000 cubic meters, the breeding depth of the breeding cage 7 can be adjusted up and down according to the breeding species, and the breeding cage 7 is tied to the four main support columns to maintain a stable shape.

[0032] A wave energy device 5 is installed on the main column of the platform away from the main frame 20 of the wind turbine generator set 1. The wave energy device 5 is an oscillating water column type. The shell of the wave energy device 5 is connected to the main column of the platform of the main frame 20 through a rigid bracket. The installation position of the wave energy device 5 is set at the lower position of the main column of the platform of the main frame 20, so that the lower end of the shell of the wave energy device 5 is half immersed in water.

[0033] A multifunctional platform 9 is provided on the upper part of the main frame 20. The platform is a C-shaped structure with a large area and carrying capacity, and can be used to place various equipment and facilities. A wind turbine 1 is provided on the multifunctional platform 9. The wind turbine 1 is located in the top corner area of ​​the main frame 20 and uses wind energy to generate electricity. The selection, quantity and layout of the wind turbine 1 can be optimized according to the local wind energy resources and the spatial conditions of the platform. In addition to the wind turbine 1, a living area module 3 and a storage tank 4 are also provided on the multifunctional platform 9. The living area module 3 provides living and working space for the platform staff, and the storage tank 4 is used to store feed and other materials required for breeding. The setting of these facilities improves the self-sufficiency and work efficiency of the platform. Photovoltaic modules 8 are provided in the edge area of ​​the multifunctional platform 9 to generate electricity using solar energy. The selection, quantity and layout of the photovoltaic modules 8 can be optimized according to the local solar energy resources and the spatial conditions of the platform to achieve the best power generation effect. A hydrogen production and storage device is also provided on the multifunctional platform 9, including a hydrogen storage tank 10 and a hydrogen production module 11. The hydrogen storage tank 10 is used to store hydrogen produced by the hydrogen production module 11, and the hydrogen production module 11 uses renewable energy to produce hydrogen by hydrolysis. The realization of this device provides a clean and efficient energy supply method for the platform.

[0034] The multifunctional platform 9 in the present application is of irregular type, with an arc shape at the center, which can leave space for the upper end of the breeding cage 7, so as to facilitate the crane 2 on the platform to deliver bait, lift nets and other operations. The rear end of the platform is of right-angle type, and the structural area is larger than that of the middle part, which is convenient for adjusting the center of the platform to the main supporting column close to the main frame 20, and at the same time facilitates the arrangement of the platform support structure to maintain the load-bearing capacity and stability of the platform.

[0035] like Figure 4As shown, the crane 2 is arranged in front of the hydrogen production and storage device. The crane 2 is located in the inner edge area of ​​the multifunctional platform 9, facing the center of the platform, and is used to assist in the operation and management of the hydrogen storage tank 10 and the hydrogen production module 11 in the hydrogen production and storage device. Since these devices may require regular maintenance, inspection or replacement of parts, the presence of the crane 2 makes these operations more convenient and efficient. By using the crane 2, the hydrogen storage tank 10 or the hydrogen production module 11 can be easily lifted or moved to facilitate the staff to perform necessary operations. In addition, if the platform needs to expand or upgrade related hydrogen energy facilities, the crane 2 can also be used to install new equipment or components. In short, the main function of the crane 2 is to provide a convenient means to handle various operations and maintenance tasks related to the hydrogen production and storage device. The multifunctional platform 9 is divided into functional areas, where the photovoltaic module 8 occupies one side of the multifunctional platform 9. Opposite the photovoltaic module 8 are the living area modules 3 and the storage tanks 4 of the container structure. The storage tanks 4 are used to store aquaculture bait and operation and maintenance equipment. The living area module 3 is used to support 2-4 people living on the platform for 14 days to ensure the life of the operators on the marine integrated platform. The multifunctional platform 9 is equipped with a hydrogen production and storage device on the side close to the wind turbine 1. The hydrogen produced by the hydrogen production module 11 is temporarily stored in the hydrogen storage tank 10 on the platform and is regularly transported out by hydrogen transport ships.

[0036] The hydrogen storage tank 10 is a container for storing compressed hydrogen, which is an important component of hydrogen energy utilization and storage. The presence of the crane 2 makes it easier to load, unload, replace or maintain the hydrogen storage tank 10, because these tanks may be heavy and difficult to carry manually. The hydrogen production module 11 is the part that produces hydrogen, and may include an electrolyzer, a compressor and other ancillary equipment. These devices require regular maintenance or upgrades. The crane 2 can help to quickly remove and install these modules, reducing downtime and maintenance costs. The multifunctional platform 9 is a structure that carries the wind turbine 1, photovoltaic panels 8, hydrogen production and storage devices, and wave energy devices 5. As part of the platform, the crane 2 enhances the functionality of the platform, enabling it to not only generate and store energy, but also have the ability to self-maintain and upgrade.

[0037] In summary, during operation, the integrated marine platform of the present invention can obtain energy through wind turbines 1, photovoltaic modules 8, wave energy devices 5, etc., to achieve diversified energy supply. At the same time, the hydrogen production and storage device on the platform can convert excess electrical energy into hydrogen for storage in case of emergency.

[0038] In terms of maintenance, the equipment and facilities on the platform can be hoisted and repaired by the crane 2. The crane 2 is arranged in the direction of the hydrogen storage tank 10 and the hydrogen production module 11 facing the center of the platform, which is convenient for hoisting and repairing various equipment and facilities on the platform.

[0039] The second object of the present invention is to provide an installation method of an integrated marine platform suitable for multi-format development, comprising: S1: placing the main frame 20 in the set seabed area, S2: Install the suction cylinder anchoring system on the main frame 20, and absorb the main frame 20 to the seabed through the negative pressure generated by the suction cylinder anchoring system; S3: Install a multifunctional platform 9 above the main frame 20; install the wind turbine 1, the photovoltaic module 8 and the hydrogen production and storage device on the multifunctional platform 9; S4: Install the wave energy device 5 on the side area of ​​the main frame 20; S5: Install the breeding cage 7 inside the main frame 20.
