Description

Technical Field

[0001] This invention relates to the field of marine resource development and utilization technology, specifically to a floating city suitable for the green development of deep-sea resources. Background Technology

[0002] A floating city is a large-scale complex of buildings moored on the sea surface, providing for human survival, production, and daily life.

[0003] The mining of deep-sea polymetallic nodules causes severe disturbance to seabed sediments, forming plumes with a wide diffusion range. Once formed, these plumes, influenced by their micron-sized particles and deep-sea currents, rapidly spread in all directions, with a horizontal propagation range reaching up to 40 km, causing irreparable damage to the marine ecosystem.

[0004] With the increase in carbon dioxide emissions in recent years, global warming has led to rising sea levels and a gradual reduction in land area in coastal regions. Mooring-based offshore structures can provide living space for humans, addressing both sea-level rise and insufficient land use in coastal areas. Current seabed mining operations rely on surface support vessels to support deep-sea mining vehicles. The collected ore and marine soil must be transported to land for processing and utilization, resulting in high costs and low efficiency, especially for deep-sea mining far from land. Therefore, existing technologies urgently need further improvement. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a floating city suitable for the green development of deep-sea resources.

The multiple connecting components are arranged sequentially along the side wall of the suspension box. Each connecting component includes two I-beams, one long and one short, arranged one above the other.

[0018] One end of each I-beam is fixedly connected to the suspension box, and the upper I-beam is fixedly welded to the bottom of the probe. The lengths of two adjacent sets of I-beams on the same side wall are arranged alternately.

[0019] The other end of each section of the I-beam on the side wall of each suspension box is bolted to the corresponding end of the I-beam on the corresponding side wall of the adjacent suspension box through two connecting plates.

[0037] The present invention will now be described in detail with reference to the accompanying drawings:

[0038] Implementation examples, in conjunction with Figures 1 to 5 A floating city suitable for the green development of deep-sea resources includes a floating platform, a disturbance device, a power generation device, a drive device, and a control system. The floating platform is composed of multiple lattice units arranged adjacent to each other and fixedly connected. Each lattice unit includes seven floating boxes 1, one of which is a central floating box, and the other six are peripheral floating boxes. The six peripheral floating boxes are distributed in a circle outside the central floating box and are fixedly connected to the six peripheral floating boxes to form a whole. The upper surfaces of all peripheral floating boxes and all central floating boxes are spliced ​​together to form a whole plane above the sea level.

[0039] The suspended platform is a semi-submersible platform with a closed cavity structure inside the suspension box. The lower part of the platform is located in seawater, and the platform, along with the supporting structure above it, floats on the sea surface. The draft of the semi-submersible platform can be adjusted by adding counterweights to its bottom, or it can be temporarily fixed by anchoring. Three propellers are installed at the bottom of the platform, arranged in an equilateral triangle. These propellers are existing large-scale marine propellers. The propellers drive the platform to move in the ocean, in conjunction with seabed mining operations.

[0040] The lower part of the suspension tank 1 is a draft regulating chamber 21, which is equipped with water supply and drainage equipment and is connected to the external seawater. The water supply and drainage equipment regulates the water volume inside the draft regulating chamber 21 by drawing seawater from and discharging seawater, thereby regulating the draft depth of the semi-submersible suspension platform. The upper middle part of the suspension tank 1 has a receiving cavity 23, which can be used to house ore processing equipment or water treatment equipment.

[0041] Specifically, the suspension box 1 is a vertically arranged regular hexagonal prism structure. The suspension box 1 includes a bottom plate 11, an outer shell 12, a partition plate 13, an inner shell 14, and a top plate 15. The inner shell 14 and the outer shell 12 are both vertically arranged regular hexagonal cylinders. The bottom plate 11 closes the lower end of the outer shell 12, and the top plate 15 closes the upper end of the outer shell 12.

[0042] The partition 13 is a regular hexagonal steel plate, horizontally arranged on the lower inner side of the outer shell 12. The outer edge of the partition 13 is fixedly and sealed to the inner wall of the outer shell 12. The partition 13, together with the bottom plate 11 and the inner wall of the outer shell 12, forms a draft regulating chamber 21. The inner shell 14 is located above the partition 13 and is arranged correspondingly to the outer shell 12. Specifically, the six sides of the inner shell 14 correspond one-to-one with the six sides of the outer shell 12 and are equally spaced.

[0043] In addition, the upper and lower ends of the inner shell 14 are fixedly and sealedly welded to the top plate 15 and the partition plate 13 respectively. The inner shell 14 and the outer shell 12 are fixedly connected by a plurality of vertical plates 16 arranged in a ring and uniformly, forming a power generation chamber 22 between the inner shell 14 and the outer shell 12. The vertical plates 16 are located at the corresponding edges of the inner shell 14 and the outer shell 12. The two sides of the vertical plates 16 are fixedly welded to the inner shell 14 and the outer shell 12 respectively. A power generation chamber 22 is formed between the six corresponding sides of the inner shell 14 and the outer shell 12. The power generation chamber 22 is used to install power generation devices. Doors can be opened on the side walls of the inner shell 14 so that personnel can enter the power generation chamber 22 through the inside of the inner shell 14 to install and maintain the equipment.

[0044] The top plate 15 is a regular hexagon. The top plate 15 extends outward relative to the side wall of the suspension box 1 to form a protrusion. The corresponding edges of any two adjacent top plates 15 are joined together, and the top plates 15 of all suspension boxes 1 are spliced ​​together to form the upper surface of the suspension platform.

[0045] Specifically, the top plate 15 is a double-layered hollow structure, comprising an upper plate, a lower plate, and a hexagonal frame. The upper and lower plates are arranged opposite each other, and their edges are fixedly welded to the hexagonal frame. The upper and lower plates are also fixedly connected by multiple stiffening plates regularly arranged inside the hexagonal frame. The stiffening plates are vertically arranged long strips of metal. The top and bottom of the stiffening plates are fixedly welded to the upper and lower plates, respectively. The function of the stiffening plates is to strengthen the structural strength of the top plate 15, giving the surface of the suspended platform high strength.

[0046] The six sides of the top plate 15 protrude outward relative to the side wall of the suspension box 1. A water flow channel is formed between the corresponding side walls of any two adjacent suspension boxes 1. A grid-like water flow channel is formed between the suspension boxes 1 in the lower part of the entire suspension platform, and seawater can flow in the water flow channel inside the suspension platform.

[0047] Each side wall of the suspension box 1 has multiple connecting components at its upper end, arranged sequentially along the side wall of the suspension box 1. Each connecting component includes two I-beams 31, one long and one short, arranged one above the other. One end of each I-beam 31 is fixedly connected to the suspension box 1, and the upper I-beam 31 is fixedly welded to the bottom of the probe. Adjacent sets of I-beams 31 on the same side wall are arranged with alternating lengths.

[0048] The other end of each I-beam 31 on the side wall of each suspended box 1 is bolted to the corresponding end of the I-beam 31 on the corresponding side wall of the adjacent suspended box 1 via two connecting plates 32. Each suspended box 1 is fixedly connected to other suspended boxes 1 around it through connecting components to form a semi-submersible floating platform floating on the sea surface. It can be moored on the sea surface and used to construct urban building complexes to provide people with living, production and survival space.

[0049] Above the floating platform, there are designated areas for urban living (101), offshore farms (102), power supply (103), ore processing (104), water treatment facilities (105), and a food processing plant (106). A carbon dioxide capture device is installed above the platform. Modular construction allows for different zones within the floating city, providing space for industrial upgrading and expansion. As a solution to urban destruction and insufficient living space caused by rising sea levels, this floating city achieves symbiosis with water by guiding the coordinated flow of energy, water, food, and deep-sea mining.

[0050] The suspended platform and the urban living area 101 above it can form a floating city at sea. Based on a semi-submersible structure design, this floating city is a large-scale marine architectural complex moored on the sea surface. The buildings in the urban living area are constructed using Biorock materials to achieve the floating city's resistance to waves and surges. Biorock materials are preferably used to construct houses, factories, and other buildings. Combined with steel structures, they possess good structural strength to withstand the impact of wind and waves. Furthermore, due to their high strength and low density, they can float on the sea surface while achieving performance three times stronger than concrete.

[0051] The urban living area is the core of the floating city, providing a means to ensure normal human life through the construction of residences, shopping malls, sports facilities, and natural landscapes. The residences, shopping malls, and other buildings are preferably constructed using Biorock materials to ensure the overall strength and stability of the city's architecture. Simultaneously, leveraging the superior marine environment, it provides tertiary industry services such as tourism, generating economic revenue for the floating city and providing financial support for further urban development and the daily maintenance of different functional areas. The urban living area also provides living space for deep-sea miners, ore smelting plant workers, personnel from passing ships, and their families, reducing the time spent traveling home to visit relatives and improving their quality of life and effective working time.

[0052] The soil in offshore farm area 102 originates from mineral soil obtained through the filtration and treatment of tailwater from deep-sea polymetallic nodule mining. During the pumping process of deep-sea polymetallic nodule mining, a large amount of seabed soil is carried to the suspended platform. Normally, this soil is filtered by the mining mother ship to remove the polymetallic nodules and discharged to the seabed, forming a deep-sea plume under strong disturbance, severely polluting the marine environment and affecting marine life. In this embodiment, this tailwater is collected and treated uniformly, separating the soil from the seawater. Preferably, soil fertility is maintained through fertilization processes before being transported to the offshore farm area as crop soil. The separated seawater can be treated and discharged into the nearby sea area of ​​the city, providing fertile soil for the growth of various crops.

[0053] The ore processing functional area 104 will refine polymetallic nodules and polymetallic sulfides collected from the seabed to obtain finished or semi-finished metal products, which will then be transported by transport ships docked at a floating platform to a land-based processing plant for further processing. The carbon dioxide capture unit is based on a chemical adsorption carbon capture process. Through the reaction between alkaline chemical reagents and carbon dioxide, liquid or solid salt products are generated in the absorption tower. Placing the stored salt products in a high-temperature environment will decompose them to generate high-concentration carbon dioxide, while unreacted alkaline chemical reagents are obtained. The alkaline chemical reagents are transported back to the absorption tower, while the carbon dioxide is transported to a high-pressure cryogenic tank for liquid storage. The stored liquid carbon dioxide is transported to a storage site via tank trucks and pipelines. Deep-sea polymetallic nodule mining can achieve deep-sea plume management through carbon dioxide extraction. On the one hand, by thoroughly mixing liquid carbon dioxide with the deep-sea plume, and under the catalytic action of NaCl carried by the seawater, large-particle, high-density carbon dioxide hydrates are produced, thereby accelerating the plume's settling velocity and reducing its diffusion range; on the other hand, under the influence of high pressure and low temperature in the deep sea, the density of liquid carbon dioxide is 1.101 g / cm³. 3 Greater than seawater by 1.02–1.07 g / cm³ 3 With its density, it can achieve deep-sea plume settling through gravity. Deep-sea carbon sequestration (greater than 3000m) achieves large-scale carbon sequestration while dissolving less carbon in seawater, thus avoiding environmental problems caused by seawater acidification. Furthermore, because its density is higher than that of seawater, the released liquid carbon dioxide will continue to sink and eventually form a "carbon lake".

[0054] The water treatment equipment area 105 can be equipped with seawater desalination equipment and water treatment equipment, preferably using reverse osmosis membrane seawater desalination technology. Seawater is sourced from the floating city mooring area, and desalination is achieved using a reverse osmosis membrane, providing a stable and high-quality water source for urban residential areas. This reverse osmosis membrane seawater desalination technology uses a nanoscale reverse osmosis membrane to separate seawater from freshwater. Pressure is increased on the seawater side to exceed its own osmotic pressure, causing pure water in the seawater to move towards the freshwater side. Simultaneously, due to the nanoscale structure of the reverse osmosis membrane, microorganisms and other tiny impurities contained in the seawater are filtered out, reducing the need for subsequent freshwater treatment processes.

[0055] The aforementioned power supply zone is located to the left of the city's core area and to the left of the energy storage and transfer station. A wind-solar hybrid power generation scheme is preferred, collecting and converting offshore wind and solar energy into usable electricity. Wave power generation and ocean thermal energy conversion technologies can also be used as supplementary technologies. The wind-solar hybrid power generation scheme involves constructing numerous wind farms in areas with abundant wind resources on the edge of the floating city, and installing photovoltaic power generation devices in the spare areas between the wind turbines to fully utilize regional resources. The power supply zone can consist of multiple hexagonal functional areas to ensure a normal power supply for the floating city.

[0056] The aforementioned energy storage and transfer station, located on the right side of the power supply zone, uses large energy storage batteries to store surplus electricity. On the one hand, it stores excess electricity when wind and solar energy are abundant, and on the other hand, it provides power supply to the floating city when wind and solar energy are scarce, so as to maintain the dynamic balance of the floating city's power demand. On the other hand, by establishing an energy storage battery replacement plant, it can provide energy storage battery replacement for passing electric-powered ships, thereby improving the ships' range and enriching the functional diversity of the floating city.

[0057] Two flow-disrupting devices are provided on each side wall of the suspended tank 1. The power generation device includes a generator 51 and a transmission mechanism. The flow-disrupting devices are connected to the rotor of the generator 51 through the transmission mechanism. The power output terminal of the generator 51 is connected to the power grid of the power protection area 103. Due to the action of ocean currents, seawater will flow in one direction for a certain period of time, impacting the side walls of the suspended tank 1 located on the periphery of the suspended platform, and flowing through the water flow channel inside the suspended platform, impacting the flow-disrupting devices on the side walls of the suspended tank 1 on the periphery of the suspended platform, and also impacting the flow-disrupting devices located on both sides of the water flow channel. In this embodiment, the flow of seawater is used to utilize the energy of the flow-disrupting devices set on the suspended platform, converting wave energy into mechanical energy, and then further converting it into electrical energy for storage. The power supply is provided for the living and production of the suspended platform through the power storage and transfer station and the power grid.

[0058] Specifically, the turbulence device includes a spoiler 41, a connecting seat 42, a guide rod 43, and a large air cylinder 44. The spoiler 41 is vertically arranged outside the suspension box 1 and vertically arranged with the corresponding side wall of the suspension box 1. The connecting seat 42 is located on the side of the spoiler 41 close to the suspension box 1, and the spoiler 41 and the connecting seat 42 are rotatably connected.

[0059] There are multiple guide rods 43, which are arranged at intervals from top to bottom and slide through the outer shell 12. The power generation chamber 22 is equipped with atmospheric cylinders 44, which are equal in number and correspond to the positions of the guide rods 43. One end of each guide rod 43 is fixedly connected to the connecting seat 42, and the other end is connected to the piston rod end of the atmospheric cylinder 44.

[0060] Each guide rod 43 is fitted with a guide sleeve 45 on its outer side, and the guide sleeve 45 is fixed to the inner side wall of the outer casing 12. Each guide rod 43 is located within its corresponding guide sleeve 45. A hinge support 46 is provided on the side wall of the spoiler 41, which is rotatably connected to the connecting seat 42. A hydraulic cylinder 47 is provided on one side of the hinge support 46, and the hydraulic cylinder 47 can drive the spoiler 41 to rotate relative to the connecting seat 42. A power generation device is provided on one side of each guide rod 43, and the power generation device is fixedly installed inside the power generation chamber 22.

[0061] The control system includes a controller, which is a conventional controller. The signal terminal of the hydraulic pump station connected to the hydraulic cylinders 47 is communicatively connected to the controller. The controller controls the extension and retraction of each hydraulic cylinder 47 via the hydraulic pump station, and the hydraulic cylinders 47 adjust the angle of the baffle 41 relative to the side wall of its respective suspension box 1. In addition, each suspension box 1 is equipped with a water flow sensor on its side wall. The signal terminal of each water flow sensor is communicatively connected to the controller to detect the seawater flow direction in each water flow channel and transmit the data to the controller in real time. The controller comprehensively analyzes the data from the water flow sensors to determine the angle of the baffle 41 inside each water flow channel and adjusts it via the hydraulic cylinders 47.

[0062] In operation, the spoilers 41 located on the outer periphery of the suspended platform and on the water-facing side remain tilted relative to their sidewalls, diverting the incoming seawater to both sides into the water flow channel. The spoilers 41 on both sides of the water flow channel adjust their angle with the water flow direction according to the water flow direction, so that the water flow forms a certain angle with the spoilers 41 on both sides of the water flow channel, and the water flow impacts the spoilers 41 on both sides of the water flow channel.

[0063] When the baffle plate 41, located on the water-facing side and inside the water flow channel, is impacted by seawater, it moves towards the side of the suspension box 1 where it is located, driving the guide rod 43 to move inward towards the suspension box 1. The guide rod 43 drives the piston inside the large air cylinder 44 through the piston rod, compressing the air inside the large air cylinder 44 located on the piston side. When the seawater recedes, the guide rod 43 moves outward towards the suspension box 1 under the air drive operation inside the large air cylinder 44, realizing the reciprocating motion of the guide rod 43 relative to the guide sleeve 45 along its axis. At the same time, the impact of the seawater inside the water flow channel on the baffle plate 41 causes the baffle plate 41 to drive the guide rod 43 connected to it to also reciprocate along its axis relative to the guide sleeve 45.

[0064] The transmission mechanism includes a one-way overrunning clutch 53 and a gearbox 52. The guide rod 43 is connected to the input end of the one-way overrunning clutch 53 through a gear and rack assembly. The output end of the one-way overrunning clutch 53 is fixedly connected to the input end of the gearbox 52 through a coupling. The output end of the gearbox 52 is connected to the rotor shaft of the generator 51.

[0065] The gear and rack assembly includes a spur gear 61 and a spur rack 62. The spur rack 62 is fixedly mounted on the top of the guide rod 43. The spur gear 61 is arranged adjacent to the upper side of the spur rack 62 and meshes with it. The gear shaft of the spur gear 61 is connected to the input end of the one-way overrunning clutch 53 via another coupling. The spur rack 62 reciprocates along the axis of the guide rod 43, driving the spur gear 61 to reciprocate. The one-way overrunning clutch 53 converts the reciprocating rotation of the spur gear 61 into a single-direction rotational output. This output drives the rotor of the generator 51 to rotate in the same direction via the gearbox 52, generating electricity. The output terminal of the generator 51 is connected to an energy storage and transfer station, which is connected to the power grid via an inverter.

[0066] A relay station 71 and a mining vehicle 72 are located on the seabed below the suspended platform. The mining vehicle 72 is connected to the relay station 71 via a suction pipe 73, which is equipped with a suction pump. The relay station 71 is connected to the ore collection bin located in the ore processing functional area 104 via a lift pipe 74. In addition, a carbon dioxide capture device located above the suspended platform is connected to the mining vehicle 72 via a delivery pipe, providing the mining vehicle 72 with supercritical carbon dioxide for ore flushing and plume settling and storage.
