Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] See Figure 1 , Figure 2 and Figure 3 The above describes a multi-functional, energy-sufficient marine integrated service platform, comprising a platform body, which includes a power generation area, an aquaculture cage area, a charging station, and a docking and charging area. The power generation area provides electricity to the platform body and vessels docked in the docking and charging area. The aquaculture cage area is located on the platform body.

[0016] The platform body adopts a modular structure, which is assembled from multiple unit structures and is equipped with at least one power compartment. The power compartment is equipped with an electric drive device to provide power for the platform body to move, turn and position.

[0017] The power generation area includes vertical axis wind turbines arranged above the main deck of the platform and solar photovoltaic panels laid on the deck and the top of the building; the main platform is also equipped with an energy storage system for storing the power generated by the power generation area and supplying it to the charging station.

[0018] The platform consists of an upper deck, a first deck below deck, and a second deck below deck. The upper deck houses the power generation area, sightseeing and leisure area, and charging station. The first deck below deck comprises a living cabin, a sightseeing cabin, and a control cabin. The second deck below deck includes ballast tanks, an energy storage system, and a cold storage cabin.

[0019] The platform also integrates a sorting and transfer cabin and lifting equipment, which are used to transfer, sort and temporarily store the catch carried by fishing vessels docked in the docking and charging area.

[0020] It also includes multiple electric fishing mother vessels that operate in conjunction with the main platform. These electric fishing mother vessels can dock at the docking and charging area and have their power replenished by the charging station. The main platform is equipped with a group control system for unified scheduling of the multiple electric fishing mother vessels.

[0021] The main body of the platform also includes a helicopter landing pad and a vegetable planting area set on the deck. The main body of the platform is also equipped with a sewage treatment unit and a seawater desalination device. The sewage treatment unit is used to treat domestic sewage and supply it to the vegetable planting area. The seawater desalination device is used to provide fresh water. The main body of the platform also includes a dynamic positioning system and an anchoring system to enable the main body of the platform to hover autonomously, move short distances, and stay stably for a long time.

[0022] Example 2, based on Example 1, features a modular, semi-submersible floating platform with overall dimensions of 75m × 40m × 6m. It is composed of 14 unit structures, each 15m × 5m × 6m in size, forming a stable rectangular frame. The 65m × 30m sea-level area enclosed within the platform frame serves as the aquaculture cage area. Intelligent aquaculture cages can be configured according to the aquaculture species and equipped with intelligent devices such as automatic feeding, water quality monitoring, and net cleaning robots.

[0023] Each of the four corner unit structures of the platform's main body is equipped with a power compartment, and each power compartment is equipped with a 100KW electric drive unit to provide power for the platform's movement, steering and positioning. Together with the dynamic positioning system and the mooring system, it enables the platform to achieve autonomous hovering and long-term stable residence.

[0024] The platform's power generation area consists of two parts: vertical axis wind turbines and solar photovoltaic panels. Fourteen 30kW vertical axis wind turbines are arranged on each unit structure, with a total power of 420kW. The turbines are 15 meters high and utilize the open offshore wind farm surrounding the platform. The solar photovoltaic panels, made of lightweight and flexible materials, are laid on the platform deck and part of the building roof, covering a total area of ​​approximately 2,500 square meters and generating approximately 210kW of power. The generated energy is prioritized for use within the platform through an energy management system (EMS), with excess energy stored in an energy storage system (located on the second level below deck, forming a stable microgrid). A charging station, including DC fast charging and slow charging piles, is located on the platform deck to provide charging services for electric vessels docked in the charging area.

[0025] The platform's spatial layout achieves vertical functional layering. The upper deck houses vertical axis fans, solar photovoltaic panels, a sightseeing and leisure area, a vegetable growing area, a sorting and transfer cabin (including lifting equipment), and a charging station. The first level below deck contains living quarters, sightseeing cabins, and a control cabin, providing living quarters, entertainment, and platform control. The second level below deck contains ballast tanks, an energy storage system (lithium-ion or flow batteries), a large cold storage cabin, and a wastewater treatment unit.

[0026] This embodiment of the platform also includes 20 electric fishing boats, each 9m x 3m in size. Each boat is equipped with a 20kW permanent magnet synchronous motor and a 50kWh lithium iron phosphate battery. The hull is made of aluminum alloy to reduce weight and increase cargo capacity. The boats operate in a "high-frequency round-trip" mode, returning to the platform after 3-4 hours of fishing at sea. They then quickly charge for one hour at the charging station's fast-charging piles in the docking and charging area. Simultaneously, the platform's lifting equipment transfers the catch to the sorting and transfer cabin, where it is sorted and temporarily stored in the freezer. The platform has a group control system that monitors the battery level, location, and catch of all boats in real time, automatically plans the optimal return-to-charge route, and can recall all boats with a single click in the event of a sudden storm, achieving intelligent cluster control. The platform also has a 600kW diesel generator as an emergency backup power source.

[0027] Example 3, based on Example 1, optimizes and expands the charging method and functional modules. To improve automation and user experience, this example upgrades the charging method of the sub-boats to inductive wireless charging. Within the platform's docking and charging area, a wireless charging transmitting coil is pre-embedded below each sub-boat docking slot, and a corresponding receiving coil is installed on the bottom of the sub-boat's hull. When the sub-boat accurately docks in the designated slot, the charging process is automatically triggered, eliminating the need for manual plugging and unplugging of the charging gun, thus achieving efficient and convenient automated charging.

[0028] Example 4 expands the sightseeing and leisure area on the upper deck and adds a transparent underwater viewing corridor, allowing visitors to observe marine life in the aquaculture cages below the platform up close. A marine science exhibition hall is added on the first level below the deck, using virtual reality (VR) technology to allow visitors to experience deep-sea exploration and offshore energy production. The platform's living quarters have also been upgraded to guest rooms and equipped with seawater desalination equipment to provide an ample supply of fresh water. The treated wastewater from the wastewater treatment unit is entirely reused in the vegetable growing area on the upper deck, achieving water resource recycling and serving as a demonstration point for ecological agriculture.

[0029] Example 5, based on Example 1, focuses on large-scale deep-sea aquaculture scenarios, emphasizing the platform's modular expansion capabilities and deep synergy between the energy system and the aquaculture system. The main platform is still composed of 14 modular structures, but depending on the scale of aquaculture, additional modular structures of the same specifications can be added horizontally or vertically, expanding the overall platform from 75m × 40m to a larger rectangular size, such as 105m × 40m or 75m × 60m. Correspondingly, the area of ​​the aquaculture cages also expands, forming a super-large closed recirculating aquaculture space.

[0030] To meet the energy demands of larger-scale aquaculture equipment, the capacity of vertical axis wind turbines and solar photovoltaic panels in the power generation area has been increased proportionally, and the energy storage system has also been expanded accordingly. The energy management system (EMS) is configured to prioritize ensuring stable power supply to the aquaculture system, ensuring that key indicators of the aquaculture environment (such as dissolved oxygen and water temperature) remain stable even under windless and sunless conditions. In this embodiment, the group control system is deeply integrated with the aquaculture system. For example, when the water quality monitoring system detects a decrease in dissolved oxygen in a localized area, the group control system can automatically dispatch nearby electric boats to dock at the platform for charging, reducing the instantaneous load on the platform's power grid, and instructing the EMS to prioritize power supply to the oxygenation equipment, ensuring aquaculture safety. Simultaneously, the platform's sorting and transfer compartments and cold storage compartments are optimized according to the market cycle of farmed fish, enabling integrated operations of large-scale harvesting, sorting, packaging, and cold chain storage, significantly improving the commercial operational efficiency of deep-sea aquaculture.
