Abstract
Description

[0002] The exploration and development of the ocean, especially the deep sea, depends on the development of marine science and technology. The emergence of any marine scientific perspective and the development of marine disciplines must be based on reliable observational data. Autonomous underwater vehicles (AUVs) are a new type of mobile marine environmental observation equipment. They possess autonomous power and navigation systems and can be equipped with various sensors to conduct dynamic and three-dimensional observations of the marine environment. However, due to limitations in battery capacity, the operating range and time of AUVs are very limited, requiring ship-based recovery stations for energy replenishment. This significantly restricts the observation range of AUVs and greatly increases observation costs. Ocean buoys and moorings are also important marine observation equipment. Similarly, due to battery capacity limitations, their operating cycle is less than 60 days, preventing them from observing marine data for extended periods. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following technical effects:
[0017] This invention proposes a high-power subsea power station based on a cluster of lifting-type propeller turbines. This deep-sea observation system consists of a lifting-type propeller turbine cluster system, an autonomous underwater vehicle (AUV), a deep-sea base station, and a buoy system. The deep-sea base station utilizes deep-sea current energy to power the AUV and its onboard sensors, eliminating the need for research vessels to dock for extended periods for refueling. The AUV is powered wirelessly. Simultaneously, the proposed system utilizes a planetary gear system to assemble three identical lifting-type propeller turbines into a power generation array. The power from the three turbines is transmitted through a sun gear and an external gear ring, and then stored in two energy storage batteries via two motors to power the buoy and the AUV.
[0018] This invention utilizes a planetary gear system to combine three lift-type helical turbines into a high-power power generation cluster. The three turbines are mounted on three planetary gears fixed to the shaft. Leveraging the torque-splitting function of the planetary gear system, the resultant torque of the three turbines is distributed between the external gear ring and the sun gear. The sun gear rotates at a high speed, and its matched small motor is mounted above the support to charge the buoy. The external gear ring rotates at a low speed, and its connected magnetic transmission device has more magnetic poles than the sun gear, achieving a higher speed ratio and increasing the speed of the motor installed in the static sealed cavity. The electrical energy generated by this motor is used to charge the underwater autonomous vehicle. The advantages of the planetary gear system allow for a compact installation of the three lift-type helical turbines, forming an equilateral triangle, with the distance between the rotation centers of adjacent turbines maintained at 1.2-2 times the turbine diameter. This achieves a coupling gain effect between the turbines, further increasing power generation. Furthermore, the equilateral triangular array arrangement provides high efficiency in most directions of incoming flow, reducing the need for yaw control. Attached Figure Description

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.
[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0031] Please see Figures 1 to 10 A high-power subsea power station based on a cluster of lifting spiral blade turbines includes a support frame 1, with a support motor 11 and a support battery 12 on the top of the support frame 1, two magnetic levitation support devices 2, a cluster of lifting spiral blade turbines 3, including three lifting spiral blade turbines 31, 32, and 33, a planetary gear mechanism 4, magnetic transmission devices 5 on both sides of the rotating shaft, with a total of two sets of upper magnetic transmission devices 51 and lower magnetic transmission devices 52, a static sealed cavity 6, which includes a generator 61, a rechargeable battery 62, an underwater vehicle 7, a wireless charging and connection device 8, a gravity base 9, a sensor system 10, a buoy sensor system 11, an underwater cable 12, and a buoy 13.
[0032] The core technologies of this invention include a lift-type helical blade turbine cluster system, a planetary gear device, a radial magnetic levitation device, a magnetic transmission device, and an underwater cluster design concept. The core technology of this patent is to utilize a planetary gear device to combine three lift-type helical blade turbines into a high-power power generation cluster. The three turbines are mounted on three planetary gears fixed to the rotating shaft. Utilizing the torque-splitting function of the planetary gear device, the resultant torque of the three turbines is distributed to the external gear ring and the sun gear. The sun gear rotates at a high speed, and its matched small motor is mounted above the support 1 to charge the buoy. The external gear ring rotates at a low speed, and the magnetic transmission device connected to it has more magnetic poles than the one connected to the sun gear, achieving a higher speed ratio and increasing the speed of the motor installed in the static sealed cavity. The electrical energy generated by this motor is used to charge the underwater autonomous vehicle. Leveraging the advantages of the planetary gear device, the three lift-type helical blade turbines can be compactly installed, forming an equilateral triangle, with the rotation center distance between adjacent turbines maintained at 1.2-2 times the turbine diameter. This achieves a coupling gain effect between the turbines, further increasing power generation. Furthermore, the equilateral triangle array arrangement is highly efficient in facing incoming flows from most directions, reducing the need for yaw devices.
[0033] Figure 1This is a system assembly diagram, in which a support frame 1 is mounted, and a support motor 11 and a support energy storage battery 12 are located on top of the support frame 1. The support motor 11 is connected to the second transmission plate 512 of the upper magnetic transmission device 51. The second transmission plate 512 of the upper magnetic transmission device 51 is electromagnetically driven by the first transmission plate 511 of the upper magnetic transmission device 51, thereby driving the support generator 11 to generate electrical energy. This electrical energy is stored in the support energy storage battery 12 to provide power for the buoy 13. The static sealed cavity 6 and the gravity base 9 are an integral structure. The static sealed cavity 6 contains a generator 61 and an energy storage battery 62. The main shaft of the generator 61 is connected to the second transmission plate 522 of the lower magnetic transmission device 52, which is also located in the static sealed cavity. The second transmission plate 522 of the lower magnetic transmission device 52 is electromagnetically driven by the first transmission plate 521 of the lower magnetic transmission device 52, thereby driving the generator 61 to generate electrical energy. This electrical energy is stored in the support energy storage battery 62 to charge the underwater autonomous vehicle 7. The torque of the upper magnetic transmission device 51 comes from the sun gear, while the torque of the lower magnetic transmission device 52 comes from the external gear ring. Since the sun gear rotates faster than the external gear ring, to increase the speed of the motor 61, the first transmission plate 521 of the lower magnetic transmission device 52 has more electrode pairs than the first transmission plate 511 of the upper magnetic transmission device 51, achieving a larger transmission ratio. Non-contact transmission is achieved through magnetic force, avoiding the need for dynamic sealing technology underwater. Three lifting-type spiral blade turbines 3 are mounted on planetary gears 42 of the planetary gear assembly 4; the planetary gears 42 can only rotate on their own axis. The underwater vehicle 7 can be charged and extended at this power generation base station via wireless charging and connection device 8, and transmit data through sensor system 10, which, along with data from buoy sensor system 11, is transmitted to the command unit via buoy 13.
[0034] Figure 2 This is a partial perspective view of the power generation unit and transmission unit, mainly explaining the connection of the motor shaft inside the support 1 and the installation of the energy storage battery inside the static sealed cavity 6. The power generation unit is the lift-type spiral blade turbine cluster 3. The upper and lower sides of the turbine cluster 3 are both first transmission plates, which are axially and radially supported by the support device 2 located at the upper end of the support and the support device 2 located in the static sealed cavity. The resultant torque of the turbine cluster 3 is transmitted to the sun gear 41 and the external gear ring 43 respectively through the planetary gear device. The high-speed sun gear 41 is connected to the first transmission plate 511 of the upper magnetic transmission device 51, transmitting the torque to the support generator 11. The low-speed external gear ring 43 is connected to the first transmission plate 521 of the lower magnetic transmission device 52, transmitting the torque to the generator 61, thereby realizing non-contact transmission between the turbine and the generator, avoiding the use of dynamic sealing technology underwater.
[0035] Figure 3This is an assembly diagram of the transmission components of the present invention, representing the core innovation of the invention. The power source for the two generators is a lift-type helical blade turbine cluster 3, which consists of three identical lift-type helical blade turbines. Each turbine has circular end plates at the top and bottom, which reduce tip loss and also serve to fix the blades and connect the planetary gears. The height-to-diameter ratio of the turbines is between 2 and 3, the distance between two adjacent turbines is 1.2 times the turbine diameter, and the phase difference between two adjacent turbines is 90 degrees. The 1.2 times distance ensures the coupling gain effect between adjacent turbines, and the 90-degree phase difference further increases the turbine coupling gain and, more importantly, reduces the torque fluctuation of the entire device. The three turbines are arranged in an equilateral triangle, which is a highly efficient power generation cluster structure. This cluster has good power generation effect facing the incoming flow from most directions, reducing the need for yaw devices. The three turbines are combined into one unit by a planetary gear device 4, which is installed on planetary gears 42 distributed in an equilateral triangle. The planetary gear shafts are fixed and can only rotate on their own axes. The planetary gear unit 4 combines the torques of the three water turbines and achieves torque distribution. The high-speed sun gear 41 is connected to the first transmission plate 511 of the upper magnetic transmission device 51, transmitting torque to the support generator 11. The low-speed external gear ring 43 is connected to the first transmission plate 521 of the lower magnetic transmission device 52, transmitting torque to the generator 61. Furthermore, to increase the speed of the generator 61, the ratio of the number of magnetic pole pairs between the first and second transmission plates of the lower magnetic transmission device 52 is 4, which is double the ratio of 2 between the first and second transmission plates of the upper magnetic transmission device 51. Assuming the resultant torque of the planetary gears is (M1+M2), the torque distribution relationship of the planetary gears is M1 / R1+M2 / R2=M / (R1+R2), where R1 is the radius of the sun gear 41, M1 is the output torque of the sun gear after distribution, R2 is the radius of the external gear ring 43, and M2 is the output torque of the external gear ring after distribution.
[0036] The innovation of combining the planetary gear mechanism with three water turbines lies not only in achieving highly efficient cluster power generation from the three lift-type helical blade water turbines, but also in ensuring that the three turbines rotate at the same speed due to the characteristics of the planetary gear mechanism, maintaining a 90-degree phase difference at all times. Simultaneously, the optimal spacing is designed to increase the coupling gain, resulting in the overall power generation cluster producing more power than the sum of the individual outputs of the three water turbines. The planetary gear device merges three rotating shafts in different positions into two output shafts. The identical shaft positions also prevent the overall device from becoming too large. Furthermore, the combination of two sets of magnetic transmission devices with different electromagnetic levels avoids dynamic sealing issues. The electricity from the two generators is stored in different batteries, enabling the different functions of the subsea power station to provide power.
[0037] Figure 4This is a front view of a lift-type spiral blade turbine cluster, showing the installation relationship of different components. The first transmission plate 521 of the lower magnetic transmission device 52 is fixedly connected to the outer gear ring, and the first transmission plate 511 of the upper magnetic transmission device 51 is connected to the central main shaft of the sun gear, with a gap maintained between them.
[0038] Figure 5 This is a schematic diagram of the internal structure of the planetary gear system. In this mechanism, the spacing and phase difference between the three lift-type helical blade turbines can be adjusted during installation. Furthermore, the number of turbines in the cluster can be increased by increasing the number of planetary gears, thereby increasing the power generation. The upper and lower planetary gears 42 are connected to the upper and lower end plates of the helical blade turbines. The planetary gear shafts are fixed, with only one degree of freedom: rotation.
[0039] Figure 6 The images show an isometric perspective view (left) and an internal structural perspective view (right) of the magnetic levitation support device. The external structure of the magnetic levitation support device 2 consists of a support device housing 21, while the internal structure comprises an external passive permanent magnet levitation bearing 22, an internal passive permanent magnet levitation bearing 23, and a spindle tip device 24. The external passive permanent magnet levitation bearing 22 is nested inside the support device housing 21, and the internal passive permanent magnet levitation bearing 23 is mounted on the outside of the spindle tip 24. Both the external and internal passive permanent magnet levitation bearings 22 and 23 are magnetized radially, with different magnetic poles inside and outside the rings. The outer ring of the inner ring and the inner ring of the outer ring share the same magnetic field. The inner ring of the passive permanent magnet levitation bearing 22 is connected to the central shaft end of the turbine 3 via the spindle tip 24, and the outer ring of the passive permanent magnet levitation bearing 22 is mounted on the support device housing 21, thus connecting to the support frame 1, and generating a radial stabilizing force using the magnetic field. The tip 24 contacts the housing 21 of the support device to generate an axial stabilizing force, thereby fixing the position of the reverse differential turbine 3 so that it can only rotate in the axial direction.
[0040] Figure 7This is a top view of the magnetic transmission device. The magnetic transmission device 5 consists of two sets of several centrally symmetrically mounted permanent magnets. These permanent magnets are magnetized along their thickness, and the magnetic poles of adjacent permanent magnets are installed in opposite directions. The magnetic pole installation direction of the permanent magnets is opposite to that of adjacent permanent magnets. Due to the principle of attraction between opposite poles and repulsion between like poles, torque can be transmitted even when misalignment occurs during magnetic transmission. This non-contact transmission allows for the elimination of dynamic sealing components, and torque transmission can be achieved using an integral static seal, greatly reducing the risk of leakage. In addition, the ratio of the rotational speeds of each pair of magnetic transmission devices is equal to the ratio of the number of magnetic poles in the magnetic transmission devices. Therefore, different speed-up ratios can be achieved by controlling the number of magnetic poles, thereby eliminating the need for the wear-prone component, the speed increaser (gearbox). This further increases the stability and reliability of the system. Therefore, the number of magnetic pole pairs of the first transmission plate 521 of the lower magnetic transmission device 52 is doubled compared to the first transmission plate 511 of the upper magnetic transmission device 51, avoiding the problem of low efficiency of the generator 61 caused by the excessively low speed of the external gear ring.
[0041] Figure 8 The diagram shows the structure of the buoy sensor system (left) and the wireless charging schematic (right). The buoy sensor system 11 consists of a wheeled system 111, a sensor system 112, a control system and energy storage module 113, a wireless charging system 114, and a sealed housing 115. The buoy sensor system 11 moves vertically on an underwater cable 12 via the wheeled system 111. During this process, the sensor system 112 measures hydrological data. During operation, the energy for the wheeled system 111 and the sensor system 112 is provided by the control system and energy storage module 113. When the energy in the control system and energy storage module 113 is less than a critical value, the buoy descends to the bottom of the underwater cable 12 and charges and exchanges information through the wireless charging device and connection device 8 installed at the deep-sea base station.
[0042] Figure 9 This is an isometric view of the underwater autonomous vehicle 7. The underwater autonomous vehicle 7 consists of an underwater autonomous vehicle body 72, a wireless charging device 73, and an observation system 71. The wireless charging device 73 is mounted on the head of the underwater autonomous vehicle body 72. The observation system 71 is mounted on the upper part of the underwater autonomous vehicle body 72.
[0043] Figure 10This is a schematic diagram of an off-grid deep-sea observation system. The deep-sea base station is lowered and fixed to the seabed by a research vessel. One or more autonomous underwater vehicles (AUVs) are released from the research vessel to nearby waters and cruise near the base station. The AUVs carry detection devices to measure long-term hydrological data. A cluster of lifting-type propeller turbines (3) rotates under the influence of water currents, converting the kinetic energy of the currents into mechanical energy. This mechanical energy is then transferred to permanent magnet generators (11, 61) via magnetic transmission devices (5), where it is converted into electrical energy and stored in energy storage systems (12, 62) as chemical energy. When the AUVs have low energy levels, they move near the deep-sea base station and dock with a wireless charging device and docking device (8). Wireless charging transfers electrical energy from the deep-sea base station to the AUVs, enabling long-term cruise. Hydrological information is then transmitted to the deep-sea base station via wireless communication. This operational mode can also be achieved by a single deep-sea base station working in conjunction with several autonomous underwater vehicles (AUVs), or by multiple deep-sea base stations working in conjunction with several AUVs, to achieve higher system stability. The buoy sensor system 11 moves vertically along the underwater cable 12 via a wheeled system 111. During this process, the sensor system 112 measures hydrological data. During operation, the energy for the wheeled system 111 and the sensor system 112 is provided by the control system and energy storage module 113. When the energy in the control system and energy storage module 113 falls below a critical value, the system descends to the bottom of the underwater cable 12, where it recharges and exchanges information via a wireless charging device and connection device 8 installed at the deep-sea base station. The deep-sea base station uploads data to a satellite via the buoy 13 floating on the water surface and receives real-time control commands transmitted from the satellite via the buoy.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
