[0011] To achieve the above objectives, the present invention provides a marine hydrogen-powered semi-submersible vessel assembly, comprising a hull equipped with a gas storage tank and a wind energy collection column assembly; the wind energy collection column assembly includes a core drive column rotatably mounted on the hull, with at least two elastic impellers connected along its length on the core drive column, and at least one elastic impeller having a helical guide duct that rotatably engages with it on its outer side; the wind energy collection column assembly is linked to a wind energy collection and power generation system, the wind energy collection and power generation system being electrically connected to a hydrogen production, compression, and storage system, and the outlet of the hydrogen production, compression, and storage system being connected to the gas storage tank.

[0017] It also includes a wave energy harvesting system, which consists of connected dynamic floating buoys and piston rods. One end of the piston rod is slidably engaged with a water-pressurizing cylinder, which is mounted on the hull. At least two rows of dynamic floating buoys are provided on both the left and right sides of the hull. In two adjacent rows of dynamic floating buoys, the row farther from the hull has fewer dynamic floating buoys than the row closer to the hull. There is a gap between adjacent dynamic floating buoys in the row farther from the hull, and this gap corresponds to a portion of the dynamic floating buoys in the row closer to the hull.

An opening is provided on the chamber body wall, and a pressure equalization flexible diaphragm is sealed at the opening. A drain check valve is also connected to the chamber body wall.

[0021] Beneficial effects

[0022] Compared with the prior art, the advantages of the marine hydrogen-powered semi-submersible vessel assembly of the present invention are as follows:

[0023] 1. When wind blows onto the spiral guide duct, due to the action of the main flow vane and tail fin, the spiral guide duct rotates until the main flow vane is basically aligned with the lateral movement path of the wind. At this point, the wind can enter the spiral guide duct from the bell-shaped opening and act on the flexible impeller, causing it to rotate. The spiral guide duct can guide the airflow directly, and the bell-shaped opening can increase the airflow collection area, while simultaneously directing the airflow to the positive power zone of the flexible impeller. Because the flexible blades slightly open in the positive power zone, increasing the wind-receiving surface, and slightly contract in the negative power zone, decreasing the wind-receiving surface, the flexible impeller achieves an improved energy conversion rate, thus maximizing collection efficiency within a limited space.

[0024] 2. Multiple wind energy harvesting columns and bending-resistant wind energy harvesting columns constitute a wind column forest. The wind energy harvesting columns are connected to the bending-resistant wind energy harvesting columns in layers via horizontal grid linkages, giving the entire wind column forest excellent wind resistance. Simultaneously, the wind column forest is a highly efficient energy-absorbing whole, minimizing the impact of sea winds on the ship's stability. The core drive column rests on the hull at its base, while its upper part is connected by horizontal grid linkages to form a whole, giving it excellent overall wind resistance and ample wind energy harvesting space. The vertical structure of the wind energy harvesting columns and bending-resistant wind energy harvesting columns significantly saves space, maximizing wind energy harvesting within the ship's limited space.

[0025] 3. By periodically traveling between the base and the windy and wave-filled sea area, the goal of low-cost and green hydrogen production can be achieved.

[0026] 4. The submersible and the air tank together provide buoyancy for the entire ship. Adjusting the water level inside the submersible adjusts the ship's actual draft, facilitating navigation and providing favorable conditions for maintenance and sea wave energy harvesting.

[0027] 5. The elevated layer features a first truss structure, which significantly reduces wave-making resistance. Furthermore, because seawater can easily pass through the area of ​​the first truss structure, it provides a better energy harvesting environment for the wave energy harvesting system, improving its wave energy harvesting efficiency and ensuring good energy harvesting performance when the ship is anchored or sailing at low speeds. By utilizing the harvested ocean energy, the ship achieves energy and freshwater self-sufficiency, greatly enhancing its range and living conditions.

[0028] 6. In the equipment layer, the wave energy harvesting system's powered buoys are distributed on both sides of the hull, while the gas storage tanks are arranged in the middle, giving the ship excellent stability while simultaneously achieving energy harvesting and gas storage functions. In the functional compartment layer, gas storage tanks are installed on both sides of the hull via a second truss structure, providing excellent conditions for the installation and performance of specialized equipment. Furthermore, the symmetrical, wide-beam layout combined with the rational arrangement of the gas storage tanks enables the ship to operate reliably and stably even in harsh sea conditions.

[0029] 7. By attaching at least two rows of dynamic floating buoys to both sides of the elongated hull, the maximum sea surface collection area can be occupied within the limited controllable area of ​​the hull. Furthermore, since the row of dynamic floating buoys furthest from the hull contains fewer buoys than the row closest to the hull, and there are gaps between adjacent buoys in the row furthest from the hull—these gaps correspond to a portion of the buoys in the row closest to the hull—this reduces the obstruction of waves by the outer buoys, increases the impact on the inner buoys, and reduces mutual interference between the buoys, thereby increasing the overall wave energy collection capacity of all dynamic floating buoys. This rational layout of the dynamic floating buoys maximizes the system's wave energy collection efficiency while simultaneously improving the overall stability of the vessel.

[0030] 8. The function of the relay air tank is to provide the air compressor system with a certain reserve and pressure, so that it can work continuously and save energy.

[0031] 9. The pressure equalization dehumidification transition chamber dehumidifies the produced humid gas at normal pressure before compression. The pressure equalization flexible diaphragm has the ability to deform, and its function is to keep the air pressure inside the chamber basically consistent with the air pressure outside the chamber, avoid excessive pressure difference between the inside and outside, reduce the probability of chamber deformation, and thus extend its service life.

[0032] 10. The core drive column is rotated by the flexible impeller and drives the DC generator. The DC generator supplies power to the electrolysis hydrogen production system, which can realize the purpose of producing and storing hydrogen in large quantities at sea for a long time, and with low energy consumption.

[0056] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0057] Example

[0058] Specific embodiments of the present invention are as follows: Figures 1 to 21 As shown, a semi-submersible marine hydrogen-powered vessel assembly includes a hull 3 on which a gas storage tank and a wind energy harvesting column assembly are installed. The wind energy harvesting column assembly includes a core drive column 12 rotatably mounted on the hull 3. At least two elastic impellers 15 are connected to the core drive column 12 along its length. At least one elastic impeller 15 has a helical guide duct 11 on its outer side that rotatably engages with it. The wind energy harvesting column assembly is linked to a wind energy harvesting and power generation system 4. The wind energy harvesting and power generation system 4 is electrically connected to a hydrogen production, compression, and storage system 5. The outlet of the hydrogen production, compression, and storage system 5 is connected to the gas storage tank.

[0059] The core drive column 12, the flexible impeller 15, and the spiral guide duct 11 constitute the omnidirectional guide duct flexible impeller machine 1. The blades of the flexible impeller 15 are made of flexible material. The blade cross-section of the flexible impeller 15 is curved.

[0060] 1. Performance comparison with ordinary impellers:

[0061] Let the incoming wind energy be q / m 2 The impeller diameter D is the same, and the omnidirectional guide duct width is 1.2D.

[0062] 1) Efficiency of the omnidirectional culvert flexible impeller Q1:

[0063] Q1 = 1.2 * 0.8 * q = 0.96q

[0064] Where: 1.2 is the windward coefficient of the positive power zone of the culvert inlet, and 0.8 is the conversion efficiency.

[0065] 2) Efficiency of ordinary impeller Q2:

[0066] Q2=0.6*0.7*q-0.4*0.2q=0.34q

[0067] Where: 0.6 is the windward coefficient in the positive power zone, and 0.7 is the conversion efficiency; 0.4 is the windward coefficient in the negative power zone, and 0.2 is the conversion efficiency.

[0068] Therefore, the efficiency of an omnidirectional duct flexible impeller is about three times that of a conventional impeller.

[0069] The wind energy harvesting column assembly includes a wind energy harvesting column 200 and a bending-resistant wind energy harvesting column 20. In the wind energy harvesting column 200, each elastic impeller 15 has a helical guide duct 11 on its outer side that rotatably engages with it. In the bending-resistant wind energy harvesting column 20, the outer side of the uppermost elastic impeller 15 has a helical guide duct 11 that rotatably engages with it. The bending-resistant wind energy harvesting column 20 is located at the center of the top surface of the hull 3, and the wind energy harvesting column 200 is located on the left and right sides of the top surface of the hull 3. The bottom of the bending-resistant wind energy harvesting column 20 may also have an elastic impeller 15 without a helical guide duct 11 on its outer side; this elastic impeller 15 is located within the second truss structure.

[0070] A tensile turntable 25 is rotatably connected to the core drive column 12 of the bending-resistant wind energy harvesting column 20. The tensile turntable 25 is connected to the hull 3 via a bending-resistant cable 27. There are at least two bending-resistant wind energy harvesting columns 20, and the tensile turntables 25 of adjacent bending-resistant wind energy harvesting columns 20 are connected by a horizontal grid frame connecting rod 26. There are at least two wind energy harvesting columns 200, and a tie rod connecting turntable 201 is rotatably connected to the core drive column 12 of the wind energy harvesting column 200. The tie rod connecting turntables 201 of adjacent wind energy harvesting columns 200 are connected by a horizontal grid frame connecting rod 26.

[0071] The spiral-shaped flow guide duct 11 has an inner cavity divided into a positive power zone and a negative power zone. A flared opening 113 and a main flow plate 118 are respectively provided on the front and rear sides of the spiral-shaped flow guide duct 11. The flared opening 113 faces the positive power zone. A positive power zone outlet 119 is provided on the side of the spiral-shaped flow guide duct 11 located in the positive power zone, and a negative power zone opening 110 is provided on the side of the spiral-shaped flow guide duct 11 located in the negative power zone. The positive power zone outlet 119 and the negative power zone opening 110 are located on opposite sides of the front end of the main flow plate 118. In this embodiment, the axis of the core drive column 12 is basically on the same plane as the main flow plate 118. The spiral-shaped flow guide duct 11 has a positive power zone baffle 111 and a negative power zone baffle 112, which form an angle and constitute a flared opening 113. The negative power zone baffle 112 is located directly in front of the negative power zone opening 110 along the windward direction. The main flow vane 118 has a tail fin 117 at its end. When the wind blows on the spiral guide duct 11, due to the action of the main flow vane 118 and the tail fin 117, the spiral guide duct 11 rotates until the main flow vane 118 is basically in line with the lateral movement path of the wind. At this time, the wind can enter the spiral guide duct 11 from the bell mouth 113 and act on the elastic impeller 15 to make it rotate.

[0072] The spiral guide duct 11 has two opposing end cap plates 114 on its wall. Each end cap plate 114 has a locking end plate 116, and the locking end plate 116 has a core shaft hole 115 through which the core drive column 12 passes. Connecting turntables 13 are connected to both the inner and outer sides of the locking end plate 116. Support rings 14 are connected to the core drive column 12. Each set of support rings 14 is coaxially arranged with the connecting turntable 13, and a first ball bearing 16 is sandwiched between them. When the core drive column 12 rotates, it drives the support rings 14 to rotate relative to the connecting turntable 13. The first ball bearing 16 reduces rotational resistance.

[0073] The spiral-shaped guide duct 11 directs the airflow directly towards the target area, while the flared opening 113 increases the airflow collection area and guides the airflow to the positive energy zone of the flexible impeller 15. After acting on the flexible impeller 15, the airflow exits from the positive energy zone outlet 119 and the negative energy zone opening 110. The negative energy zone opening 110 increases exhaust flow and reduces resistance in the positive energy zone. Because the flexible impeller 15 has a larger surface area for airflow in the positive energy zone and a smaller surface area in the negative energy zone, it improves energy conversion efficiency, thereby maximizing collection efficiency within a limited space.

[0074] The hull 3 comprises, from bottom to top, a submersible 31, an elevated deck 32, an equipment deck 33, a functional cabin deck 34, and a roof deck 35. The functional cabin deck 34 has a functional cabin deck 341. The elevated deck 32 has a first truss structure connecting the submersible 31 and the functional cabin deck 341, and gas storage tanks are mounted on the first truss structure. The gas storage tanks include a hydrogen storage tank 56 and an oxygen storage tank 57.

[0075] The first truss structure includes at least two rows of longitudinally arranged steel columns 323. The lower ends of the steel columns 323 are connected to the submersible hull 31, the middle sections of the steel columns 323 pass through the functional cabin deck 341 and are fixedly connected to it, and the upper ends of the steel columns 323 are connected to the ship roof 351. The other end of the anti-bending cable 27 is connected to the column top cable fixing point 3231 at the top of the steel column 323. The first truss structure also includes at least two gas tank bearing beams 331, each gas tank bearing beam 331 is connected to a row of at least two steel columns 323, and the gas tanks are installed between the two parallel gas tank bearing beams 331. In this embodiment, multiple gas tanks are arranged sequentially on the first truss structure along the centerline of the hull 3.

[0076] The roof deck 35 is equipped with a roof 351, and the functional cabin deck 34 also contains several rooms 342. Rooms 342 include a high-pressure jet drive room, an electrolysis hydrogen / oxygen production heat energy recovery room, an oxygen compressor room, a gas compression heat energy recovery room, a hydrogen compressor room, an open-type generator room, a seawater desalination room, a seawater desalination heat energy recovery room, living quarters 1 and 2, a power storage room, and a power distribution room. The functional cabin deck 341, rooms 342, and roof 351 are connected sequentially from bottom to top. The roof 351 and the functional cabin deck 341 are connected on their outer sides by a second truss structure, the lower part of which houses a gas storage tank. The core drive column 12 is rotatably connected to the roof 351 and the second truss structure. In this embodiment, each bending-resistant wind energy collection column 20 is arranged in a row along the centerline of the hull 3 and installed on the roof 351 of the ship. Each wind energy collection column 200 is arranged in four rows and symmetrically arranged on the second truss structure on the left and right sides of a row of bending-resistant wind energy collection columns 20.

[0077] The second truss structure includes at least two cantilever trusses 29 connecting the left and right outer sides of the roof 351 and the functional cabin deck 341, with the cantilever trusses 29 extending to the bottom of the roof 351. Horizontal connecting rods 332 connect adjacent cantilever trusses 29, and gas storage tanks are installed between the lower parts of adjacent cantilever trusses 29. Furthermore, cross connecting rods 333 can connect adjacent cantilever trusses 29 to further enhance the rigidity of the second truss structure. A pressure tank body 63 is connected to the cantilever trusses 29.

[0078] The submersible hull 31 contains multiple ballast tanks for storing seawater, and together with the air tank, it provides buoyancy for the entire vessel. Adjusting the water level within the submersible hull allows for control of the vessel's actual draft, facilitating navigation, maintenance, and maintaining optimal wave energy harvesting conditions. The stern of the submersible hull 31 features a jet nozzle structure 322. This jet nozzle structure 322 can adopt the high-pressure jet drive system structure disclosed in patent number 202122082504.0. This structure utilizes the high-pressure water generated by the system for direct propulsion, significantly shortening the energy conversion path and improving the efficiency of zero-carbon navigation.

[0079] The submersible body 31 is connected to a horizontally extending bottom support 321 on its outer side. The bottom support 321 is located below the second truss structure. The power float 61 is located between the bottom support 321 and the second truss structure. The lower end of the piston rod 62 is slidably connected to the bottom support 321.

[0080] The marine hydrogen-powered semi-submersible vessel assembly also includes a wave energy harvesting system 6. The wave energy harvesting system 6 comprises connected dynamic floats 61 and a piston rod 62. One end of the piston rod 62 is slidably engaged with a pressure cylinder 63, which is mounted on the hull 3. At least two rows of dynamic floats 61 are provided on both the left and right sides of the hull 3. In adjacent rows of dynamic floats 61, the row furthest from the hull 3 has fewer dynamic floats 61 than the row closest to the hull 3. A gap 60 is left between adjacent dynamic floats 61 in the row furthest from the hull 3, and this gap 60 corresponds to a portion of the dynamic floats 61 in the row closest to the hull 3.

[0081] One end of the pressure tank 63 is connected to a water inlet 64 and a high-pressure water network 66. Both the water inlet 64 and the high-pressure water network 66 are equipped with one-way valves 65 to ensure that when the powered floating buoy 61 descends, the pressure tank 63 drives the water inlet 64 to draw seawater from the sea surface, and when the powered floating buoy 61 rises, the water in the pressure tank 63 is forced into the high-pressure water network 66 by the piston rod 62. The high-pressure water network 66 is arranged on the roof 351 of the roof layer 35.

[0082] The output end of the high-pressure water pipeline 66 is connected to the inlet end of the high-pressure water turbine 672 via a self-controlled solenoid valve 673. The outlet end of the high-pressure water turbine 672 is equipped with a drain outlet 68. The high-pressure water turbine 672 is linked to a second DC generator 671. After high-pressure water enters the high-pressure water turbine 672, it drives the turbine to rotate and drives the DC generator 671 to generate electricity. The water is then discharged from the drain outlet 68. The self-controlled solenoid valve 673, the high-pressure water turbine 672, and the DC generator 671 together constitute the high-pressure water turbine power generation mechanism 67.

[0083] The core drive column 12 is linked to a power generation transmission mechanism 2. The power generation transmission mechanism 2 includes a meshing first gear 21 and a second gear 22, with the second gear 22 coaxially connected to the core drive column 12. The power generation transmission mechanism 2 also includes a connecting support 23, which is fixed to the cantilever truss 29. The connecting support 23 includes a support cover plate and a support plate located on the upper and lower sides of the second gear 22, respectively, with the support cover plate connected to the support plate. A second ball bearing is provided between the second gear 22 and the support plate to reduce the rotational friction of the core drive column 12. The connecting support 23 provides a vertical limit for the second gear 22, reducing the vertical sway of the core drive column 12.

[0084] The wind energy harvesting and power generation system 4 includes a first drive shaft 41, a first drive gear set 42, an energy collection drive shaft 43, a second drive gear set 44, and a first DC generator 45, which are linked in sequence. The first gear 21 is connected to the first drive shaft 41. When the core drive column 12 rotates, it can drive the first DC generator 45 to generate electricity.

[0085] When the sea breeze acts on the main flow plate 118 of the spiral guide duct 11, the spiral guide duct 11 deflects until the main flow plate 118 is parallel to the lateral flow direction of the sea breeze. At this time, the wind blows into the spiral guide duct 11 from the bell mouth 113 and acts on one side of the elastic impeller 15, causing the elastic impeller 15 to drive the core drive column 12 to rotate in one direction. Then the wind blows out from the opening on the rear side of the spiral guide duct 11. Multiple core drive columns 12 correspond to the same energy collection drive shaft 43. The first transmission gear set 42 uses two meshing bevel gears. At least one of the two bevel gears is linked to its shaft through a one-way ratchet, ensuring that the kinetic energy of the core drive column 12 is unidirectionally transmitted to the energy collection drive shaft 43 only when the sea breeze drives the core drive column 12 to rotate. The energy-collecting drive shaft 43 drives the first DC generator 45 to generate electricity through the second transmission gear set 44. The electrical energy flows to the power distribution room of the ship 3 in the form of DC electricity and supplies power to the electrolysis hydrogen production system 51.

[0086] The hydrogen production, compression, and storage system 5 includes an electrolytic hydrogen production system 51, which has a hydrogen outlet 511 and an oxygen outlet 512. Along the gas path, a pressure equalization and dehumidification transition chamber 52, a pump body 53, a relay storage tank 54, and an air compression system 55 are sequentially connected between the hydrogen outlet 511 and the hydrogen storage tank 56, and between the oxygen outlet 512 and the oxygen storage tank 57. A first DC generator 45 is electrically connected to the DC power input terminal 514 of the electrolytic hydrogen production system 51. The electrolytic hydrogen production system 51 also has a water inlet 513.

[0087] In this embodiment, the pump body 53 adopts the diaphragm pump with patent number 2020230459648, and the air compression system 55 adopts the green circular air compression system with patent number 2021228070015.

[0088] Distilled water enters the electrolytic hydrogen production system 51, where it is electrolyzed into hydrogen and oxygen using direct current. The hydrogen and oxygen are then removed from the electrolytic hydrogen production system 51 through the hydrogen outlet 511 and oxygen outlet 512, respectively. Since both hydrogen and oxygen contain a certain amount of water vapor, they need to enter their respective pressure equalization and dehumidification transition chambers 52 for dehumidification.

[0089] The pressure equalization and dehumidification transition chamber 52 includes an inlet pipe 522, a chamber body 521, and an outlet pipe 523 connected in sequence. The inlet pipe 522 is connected to the gas output port of the electrolytic hydrogen production system 51, and the outlet pipe 523 is connected to the pump body 53. A dehumidification coil 528 is installed inside the chamber body 521, with a dehumidification cold pipe inlet 524 and a dehumidification cold pipe outlet 525 extending out of the chamber body 521 at both ends. An opening is provided on the wall of the chamber body 521, and a pressure equalization flexible diaphragm 527 is sealed at the opening. Coolant flows through the dehumidification coil 528. Taking hydrogen as an example, after hydrogen enters the chamber body 521 through the inlet pipe 522, the dehumidification coil 528 cools the water vapor, causing it to condense into water droplets that fall to the bottom of the chamber body 521. The dried hydrogen then flows out through the outlet pipe 523. The pressure equalizing flexible diaphragm 527 is located in the middle of the side wall of the cabin 521. The pressure equalizing flexible diaphragm has the ability to deform. Its function is to keep the air pressure inside the cabin basically the same as the air pressure outside the cabin, avoid excessive pressure difference between the inside and outside, reduce the probability of cabin deformation, and thus extend its service life.

[0090] A drain check valve 526 is also connected to the wall of compartment 521. Water condensed inside compartment 521 is drained away through drain check valve 526.

[0091] One-way valves 58 are connected between the pump body 53 and the relay gas storage tank 54, between the air compression system 55 and the hydrogen storage tank 56, and between the air compression system 55 and the oxygen storage tank 57. The gas (hydrogen or oxygen) passing through the pump body 53 is pressurized to 0.2-0.3 MPa, stored at 0.5 MPa in the relay gas storage tank 54, and further pressurized to 8 MPa by the air compression system 55 before being stored in the hydrogen storage tank 56 or the oxygen storage tank 57.

[0092] The production of the marine hydrogen-powered semi-submersible vessel assembly can continue 24 hours a day, whether it is moored or sailing at low speed. In order to achieve better economic benefits, the marine hydrogen-powered semi-submersible vessel assembly can periodically (generally about 10 days) travel between the base and windy and wavery (high energy density) sea areas to achieve the goal of low-cost green hydrogen production.

[0104]

[0105] (2) Calculation of hydrogen and oxygen production

[0106] The energy conversion rate of electrical energy to hydrogen energy and compressed to 8 MPa is calculated as 87%.

[0107] 25315065*0.87 / 3.2=6882533.3m 3

[0108] That is, 6,882,533.3 m³ of hydrogen and 3,441,266.6 m³ of oxygen were produced. 3 .

[0109] (3) Platform overall cost estimation

[0110]

[0111] (4) Project cost payback period calculation

[0112] The value of oxygen and sea salt is added to hydrogen, at a price of 1.8 yuan / m³. 3 Calculate the project payback period R:

[0113] R = 4253.24 * 10000 / (6882533.3 * 1.8) = 3.43 years.

[0114] The project has an annualized rate of return of 29.1%.

[0115] The system directly converts the wind energy collected by the wind turbine into direct current (DC) through a unidirectional mechanical transmission. This DC power is then used directly for hydrogen electrolysis, seawater distillation, gas compression, and battery charging, eliminating intermediate conversion or storage steps and minimizing losses.
