Description

Technical Field

[0001] This invention relates to the field of new energy and marine equipment, and in particular to a marine wind power generation system. Background Technology

[0002] With the implementation of the "dual carbon" strategy, "green ships" under the green economy have become the future development trend. This has led to the International Maritime Organization introducing more stringent ship energy efficiency design indices, which also puts forward higher requirements for the energy-saving and emission-reduction design of ships. How to reduce carbon emissions while meeting the ship's navigation power needs has become the focus of ship design research.

[0003] Wind power, as an important component of the new energy system, has seen rapid development in recent years. Abundant offshore wind resources have made offshore wind power generation a current hot topic, and deploying wind power generation devices on ships has become a favored design solution for energy conservation and emission reduction in vessels. However, most ship types, such as liquefied gas carriers, bulk carriers, and container ships, already have a large amount of equipment on their decks, leaving limited space for wind power generation devices. Currently, the power output of mainstream horizontal axis wind turbines is typically proportional to the rotor diameter; to effectively capture wind energy, large turbines are required, necessitating even more installation space. This space constraint presents challenges to the design of current marine wind power generation devices. Furthermore, directly storing redundant electricity generated by wind power generation devices would result in excessively high storage and transportation costs. Therefore, designing a wind power generation device that can fully utilize existing ship space, effectively capture wind energy, and store electricity at low cost is essential. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a marine wind power generation system that utilizes the high-altitude areas on both sides of the superstructure, employing a rotating platform to connect cascaded wind turbines for power generation. This system achieves the same power output as large wind turbines while offering flexible layout options, resolving the issue of conflicting space constraints. Furthermore, the conversion of redundant electrical energy into hydrogen energy through hydrogen production equipment eliminates the problems of storage and transportation costs.

[0005] To achieve the above and other related objectives, the present invention provides a marine wind power generation system, which includes a stacked wind power generation device and a hydrogen production and storage device. The stacked wind power generation device consists of a rotating platform and a stacked wind turbine frame equipped with a generating wind turbine. The rotating platform is vertically arranged in the high-altitude area on the left and right sides of the superstructure, and the stacked wind turbine frame is stacked and connected to the front side of the rotating platform.

[0006] The hydrogen production and storage device includes a hydrogen production unit and a high-pressure gaseous hydrogen storage unit, which uses the electricity generated by the stacked wind power generation unit to electrolyze water to produce and store hydrogen. The hydrogen production unit and the high-pressure gaseous hydrogen storage unit are arranged in a separate compartment below the deck of the superstructure area.

[0007] Preferably, the rotating platform is provided with five rotating shafts on the side of the superstructure to connect to the side wall of the superstructure. The rotating shafts are evenly arranged along the vertical direction of the side wall of the superstructure. With the side wall of the superstructure as the reference plane, the rotation angle range of the rotating platform is from 10° to 170°.

[0008] Preferably, the lower end of the rotating platform is provided with a column structure that can move in the vertical direction. When the rotating platform rotates, the column structure is retracted to be flush with the lower edge of the rotating platform. When the stacked wind power generation device is working or in a fixed position, the column structure is lowered until it reaches the bottom of the deck slot on the deck and is fixedly connected to the deck slot, thereby providing vertical support for the stacked wind power generation device and bearing the axial thrust of the wind turbine generated during wind power generation.

[0009] Preferably, below the positions of the rotating platform at rotation angles of 10°, 45°, 90°, 135°, and 170°, at least two evenly spaced deck slots are arranged radially on the deck.

[0010] Preferably, the deck slot has a circular perforation, and the lower end of the column structure also has a circular perforation. When the column structure is lowered, a pin is used to pass through the circular perforation on the column structure and the deck slot to fix the column structure to the deck slot.

[0011] Preferably, the stacked fan frame is connected to the front of the rotating platform by four hydraulic lifting devices arranged at the corners.

[0012] Preferably, the generating wind turbine is a small horizontal axis wind turbine, and the stacked wind turbine frame is evenly divided into multiple grid areas along its length and height. A small horizontal axis wind turbine is arranged in each grid area, and the small horizontal axis wind turbine is fixed to the stacked wind turbine frame by a steel frame.

[0013] Preferably, the stacked wind turbine frame has a rectangular structure and extends beyond the ship's side.

[0014] Preferably, the stacked wind power generation device transmits the generated electricity to a transformer, which then transmits it to a distribution box. Both the transformer and the distribution box are located in the distribution room below the deck of the superstructure area.

[0015] Preferably, the hydrogen production equipment consists of an electrolyzer and a seawater desalination device. When the hydrogen production equipment is working, the electrolyzer receives electrical energy from the power distribution box, while the seawater desalination device injects desalinated and filtered seawater into the electrolyzer to produce hydrogen. The high-pressure gaseous hydrogen storage equipment consists of a hydrogen purification device, a hydrogen compressor, and a hydrogen storage tank. The hydrogen produced by the hydrogen production equipment is compressed and stored in the hydrogen storage tank after passing through the hydrogen purification device and the hydrogen compressor.

[0016] As described above, the present invention provides a marine wind power generation system with the following beneficial effects: When a ship is sailing at sea, the wind power generation device will adopt different equipment arrangements according to the wind speed. First, under non-operating wind speeds, i.e., no wind or excessively high wind speeds, the device will retract the column of the rotating platform and rotate the rotating platform along the axis of rotation to make it flush with the side wall of the superstructure, thereby reducing the impact of the wind power generation device on the ship's speed and avoiding structural damage to the superstructure caused by the large thrust generated by excessively high wind speeds; under operating wind speeds, in order to effectively capture wind energy from different directions, the rotation angle of the rotating platform can be adjusted to ensure that the wind turbine has sufficient windward area to collect more wind energy; at the same time, the four corner points of the stacked wind turbine frame are lifted to different heights by a hydraulic jacking device, so that the stacked wind turbine frame forms a suitable angle with the incoming wind, thereby obtaining a suitable angle of attack of the blades to achieve the optimal tip speed ratio, thereby ensuring the maximum wind energy capture rate. Furthermore, compared to conventional large wind turbines, this system employs a stacked layout of multiple small horizontal-axis wind turbines. This not only ensures power generation comparable to large turbines but also reduces manufacturing and maintenance costs. Simultaneously, this structure allows for flexible arrangement of the stacked turbine racks to suit different ship types, superstructure dimensions, and deck sizes, effectively resolving space constraints. Moreover, the stacked turbine racks can extend beyond the deck, utilizing the space outside the ship's hull for wind energy capture, further leveraging abundant offshore wind resources to meet some of the ship's electricity needs. This wind power generation system can also convert excess electrical energy into hydrogen energy for storage, which has lower storage and transportation costs, through hydrogen production and high-pressure gaseous hydrogen storage equipment, thus addressing cost issues. Overall, this system effectively promotes low-carbon and green ship operations. Attached Figure Description

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

[0027] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0028] like Figures 1 to 4 As shown, the present invention provides a marine wind power generation system, specifically including: a stacked wind power generation device 21 and a hydrogen production and storage device 22. The stacked wind power generation device 21 consists of a rotating platform 1 and a stacked wind turbine frame 2 equipped with a generating wind turbine. The rotating platform 1 is vertically arranged in the high-altitude area on the left and right sides of the superstructure 5, and the stacked wind turbine frame 2 is stacked and connected to the front side of the rotating platform 1. The hydrogen production and storage device 22 includes a hydrogen production device 3 and a high-pressure gaseous hydrogen storage device 4, which uses the electricity generated by the stacked wind power generation device 21 to electrolyze water to produce and store hydrogen. The hydrogen production device 3 and the high-pressure gaseous hydrogen storage device 4 are arranged in an independent compartment below the deck of the superstructure area.

[0029] Specifically, the rotating platform 1 is vertically arranged in the high-altitude area on the left and right sides of the superstructure 5, and adopts a rectangular structure with the same length and width as the stacked wind turbine frame 2. The rotating platform 1 is provided with a rotating shaft 8 on the side of the superstructure 5 to connect to the side wall of the superstructure. There are five rotating shafts 8 in total, and they are evenly distributed along the vertical direction of the side wall of the superstructure 5. With the side wall of the superstructure 5 as the reference plane, the rotation angle range of the rotating platform 1 can be from 10° to 170°.

[0030] Furthermore, such as Figure 4 As shown, the lower end of the rotating platform 1 is provided with a column structure 9, which can move in the vertical direction. When the rotating platform 1 rotates, the column structure 9 will be retracted to be flush with the lower edge of the rotating platform 1. When the stacked wind power generation device is working or in a fixed position, the column structure 9 will be lowered until it reaches the bottom of the deck slot 10 located on the deck and is fixedly connected to the deck slot 10. In this way, the stacked wind power generation device 21 is provided with vertical support and the axial thrust of the wind turbine generated during wind power generation is borne. The deck slot 10 is located on the deck on the left and right sides of the superstructure 5.

[0031] Furthermore, below the rotating platform 1 at rotation angles of 10°, 45°, 90°, 135°, and 170°, at least two evenly spaced deck slots 10 are arranged radially on the deck. Each deck slot 10 has a circular perforation 20, and the lower end of the column structure 9 also has a circular perforation 20. When the column structure 9 is lowered, a pin can be inserted through the circular holes on both the column structure 9 and the deck slot 10 to secure the column structure 9 to the deck slot 10.

[0032] When a ship is sailing at sea, the wind power generation device will adopt different equipment arrangements according to the wind speed. First, in the case of non-operating wind speed, that is, no wind or excessive wind speed, the device will retract the column structure 9 of the rotating platform 1 and rotate the rotating platform 1 along the rotating shaft 8 to make it flush with the side wall of the superstructure 5, so as to reduce the impact of the wind power generation device on the ship's speed and avoid damage to the superstructure structure due to the large thrust generated by excessive wind speed. In the case of operating wind speed, in order to effectively capture wind energy from different directions, the rotation angle of the rotating platform 1 can be adjusted to ensure that the wind turbine has sufficient windward area to collect more wind energy.

[0033] Furthermore, the stacked wind turbine frame 2 is connected to the front of the rotating platform 1 by four hydraulic lifting devices 11 arranged at the corners; so as to adjust the pitch angle of the stacked wind turbine frame 2, so that a suitable angle is formed between the stacked wind turbine frame 2 and the incoming airflow, thereby obtaining a suitable angle of attack of the blades to achieve the optimal tip speed ratio, so as to ensure the maximum wind energy capture rate.

[0034] Furthermore, the generating wind turbine is a small horizontal axis wind turbine 12. The stacked wind turbine frame 2 is evenly divided into multiple grid areas along its length and height. A small horizontal axis wind turbine 12 is arranged in each grid area, and the small horizontal axis wind turbine 12 is fixed to the stacked wind turbine frame 2 by a steel frame. The stacked wind turbine frame 2 adopts a rectangular structure. Its length and width need to be determined according to the height of the superstructure 5, the distance between the side wall of the superstructure 5 and the ship's side, the rotor diameter and power generation of the small horizontal axis wind turbine 12, and the total power generation. The stacked wind turbine frame 2 can also extend partially beyond the ship's side as needed. In addition, for the selection of the small horizontal axis wind turbine 12, after comprehensively considering wind energy utilization efficiency and manufacturing cost, the device will adopt a three-bladed wind turbine. Compared to conventional large wind turbines, this device adopts a stacked layout of multiple small horizontal axis wind turbines, which not only ensures power generation comparable to large wind turbines, but also reduces manufacturing and maintenance costs. At the same time, this structure allows for easy adjustment of the stacked wind turbine frames according to the size and form of the superstructure and deck dimensions of different ship types, providing flexibility in layout and effectively solving the problem of conflicting layout space.

[0035] The stacked wind power generation device 21 transmits the generated electricity to the transformer 13, and then the transformer 13 transmits it to the distribution box 14. The transformer 13 and the distribution box 14 are both located in the distribution room 23 below the deck of the superstructure area.

[0036] like Figure 2As shown, both the hydrogen production equipment 3 and the high-pressure gaseous hydrogen storage equipment 4 are located in an independent compartment 7 below the deck of the superstructure area, adjacent to the power distribution room 23. The hydrogen production equipment 3 consists of an electrolyzer 15 and a seawater desalination device 16. When the hydrogen production equipment 3 is working, the electrolyzer 15 receives electrical energy from the power distribution box 14, while the seawater desalination device 16 injects desalinated and filtered seawater into the electrolyzer 15 to produce hydrogen. The high-pressure gaseous hydrogen storage equipment 4 consists of a hydrogen purification device 17, a hydrogen compressor 18, and a hydrogen storage tank 19. The hydrogen produced by the hydrogen production equipment 3 is compressed and stored in the hydrogen storage tank 19 after passing through the hydrogen purification device 17 and the hydrogen compressor 18.

[0037] In summary, this invention provides a marine wind power generation system with the following beneficial effects: When a ship is sailing at sea, the wind power generation device will adopt different equipment arrangements according to the wind speed. First, under non-operating wind speeds, i.e., no wind or excessively high wind speeds, the device will retract the column of the rotating platform and rotate the rotating platform along the axis of rotation to make it flush with the side wall of the superstructure, thereby reducing the impact of the wind power generation device on the ship's speed and avoiding structural damage to the superstructure caused by the large thrust generated by excessively high wind speeds. Under operating wind speeds, in order to effectively capture wind energy from different directions, the rotation angle of the rotating platform can be adjusted to ensure that the wind turbine has sufficient windward area to collect more wind energy. At the same time, the four corners of the stacked wind turbine frame are lifted to different heights by a hydraulic jacking device, so that the stacked wind turbine frame forms a suitable angle with the incoming wind, thereby obtaining a suitable angle of attack of the blades to achieve the optimal tip speed ratio, thus ensuring the maximum wind energy capture rate. Furthermore, compared to conventional large wind turbines, this system employs a stacked layout of multiple small horizontal-axis wind turbines. This not only ensures power generation comparable to large turbines but also reduces manufacturing and maintenance costs. Simultaneously, this structure allows for flexible arrangement of the stacked turbine racks to suit different ship types, superstructure dimensions, and deck sizes, effectively resolving space constraints. Moreover, the stacked turbine racks can extend beyond the deck, utilizing the space outside the ship's hull for wind energy capture, further leveraging abundant offshore wind resources to meet some of the ship's electricity needs. This wind power generation system can also convert excess electrical energy into hydrogen energy for storage, which has lower storage and transportation costs, through hydrogen production and high-pressure gaseous hydrogen storage equipment, thus addressing cost issues. Overall, this system effectively promotes low-carbon and green ship operations.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
