Description

Technical Field

[0001] This invention relates to the field of marine renewable energy power generation technology, and in particular to a multi-energy integrated power generation platform system. Background Technology

[0002] The ocean is rich in renewable energy sources such as wind, solar, and wave energy. Compared to land, offshore wind energy has advantages such as high and stable wind speeds and does not occupy land resources; offshore solar energy is less affected by terrain obstruction; and wave energy can be utilized continuously around the clock. Developing offshore multi-energy complementary power generation platforms, which integrate the collection, conversion, and transmission of multiple energy sources into a single platform structure, can improve the utilization rate of marine space and the power generation efficiency per unit area, while reducing the unit cost of power generation. This has become an important development direction for marine renewable energy development. Currently, offshore power generation platforms mainly adopt floating structures, positioned by mooring systems. Wind turbines and solar photovoltaic panels are installed on the platform, and some platforms also integrate wave energy generation devices to achieve complementary utilization of multiple energy sources.

[0003] Existing offshore multi-energy complementary power generation platforms have the following problems in practical use: First, wave energy generation generally adopts an oscillating float or oscillating body structure. Wave energy is captured by the float and converted into hydraulic energy by a hydraulic rod, which then drives the generator to generate electricity. This method includes a hydraulic transmission system, with a complex mechanical structure and many sealing components, resulting in high maintenance costs and a high failure rate in the corrosive seawater environment. Second, the platform's ability to withstand extreme sea states is insufficient. Under severe weather conditions such as typhoons, the platform sways violently, and wind turbines and solar photovoltaic panels are easily damaged. The ballast adjustment of existing platforms only acts on the wave energy float or is used for dynamic leveling of the platform, and cannot lower the center of gravity and reduce wave loads by the overall buoyancy and sag of the platform. Third, the platform's load-bearing structure is mostly a single float plus mooring anchor chain, which has limited structural rigidity and stability. Under wave action, the platform sways significantly, affecting power generation efficiency and equipment lifespan. Fourth, existing wave energy generation devices are mostly located on the outside of the platform or around the bulwark, directly exposed to the seawater environment, resulting in prominent corrosion and biofouling problems, and cannot utilize the overall platform movement with the waves to drive power generation.

[0004] To address the aforementioned issues, a search revealed patent publication number CN117365845A, which discloses a floating wind-solar-wave energy complementary offshore power generation platform. The principle involves arranging wind and photovoltaic power generation modules on the floating platform, and oscillating wave energy generation modules arranged circumferentially around the platform's bulwark. Each wave energy generation module includes a float and hydraulic rods. The float, under the influence of waves, drives the hydraulic rods to generate hydraulic energy, which is then used to generate electricity via a hydraulic motor. The float has a ballast water tank inside, which can be adjusted to submerge the float below the water surface and lock it securely to the platform. The advantages of this solution are that it achieves multi-energy complementarity of wind, wave, and solar energy, and the float can be submerged to protect the wave energy module. However, its disadvantages include the use of hydraulic transmission for wave energy generation, resulting in a complex structure and high maintenance costs; the ballast water tank being only located inside the float and only able to adjust the float's draft, not the overall buoyancy of the platform; the platform using mooring chains for positioning and lacking a composite load-bearing structure; and the wave energy module being located outside the platform and directly exposed to the seawater environment. For example, patent publication number CN224159406U discloses an integrated wind, solar, and wave energy offshore power generation platform. Its principle involves setting a vertical axis wind power generation module above a circular floating platform, an oscillating float-type wave energy generation module below the platform, and photovoltaic power generation modules on the platform's surface. Wave energy is converted into electrical energy via hydraulic cylinders and hydraulic motor generators. The advantage of this solution is that the vertical axis wind turbine is not limited by wind direction; its disadvantage is that wave energy generation uses a hydraulic transmission structure, and the platform lacks active buoyancy adjustment capabilities. Patent publication number CN121760885A discloses a wind-resistant integrated wind and wave energy power generation platform. Its principle involves setting a ballast water tank within the base of the floating platform, and adjusting the ballast water distribution through a water pump to change the platform's center of gravity to prevent capsizing. The advantage of this solution is that the ballast water tank can dynamically adjust the platform's stability; its disadvantage is that it only integrates wind and wave energy, lacks solar power generation, the ballast water tank is used for dynamic leveling rather than achieving the entire platform's buoyancy and submersion, and wave energy generation still uses a hydraulic transmission method. Furthermore, nano-triboelectric generators convert mechanical energy into electrical energy using the principles of triboelectricity and electrostatic induction. They are characterized by simple structure, no mechanical transmission components, good low-frequency response, and high reliability. While research on using nano-triboelectric generators for wave energy harvesting exists, it primarily focuses on low-power scenarios such as powering micro-sensors or self-powering marine buoys. No large-scale integration of nano-triboelectric generators into the interior of offshore power generation platforms, sharing the platform structure and power transmission system with wind and solar power generation, has yet to be seen. Based on the shortcomings of existing technologies, a multi-energy combined integrated power generation platform system is needed. This system integrates nano-triboelectric generators into the interior of the platform, utilizes ballast tanks to achieve active buoyancy of the entire platform, and employs a truss-floating composite support structure. This would address the problems of complex wave energy generation structures, difficult maintenance, insufficient platform resistance to extreme sea conditions, and poor structural stability in existing technologies. Summary of the Invention

[0005] This invention provides a multi-energy integrated power generation platform system that solves the problem of how to integrate wind, solar and wave energy on a floating platform at sea to achieve multi-energy complementarity and continuous and stable power supply. At the same time, it improves the stability of the platform and the protection of power generation equipment under extreme sea conditions such as typhoons by actively adjusting the platform's floating state through ballast tanks and the composite support structure of truss floats.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A multi-energy combined integrated power generation platform system includes a power generation system platform, a wind power generation mechanism, a solar power generation system, and a power generation combined system cabin; the power generation system platform is located on top of the power generation combined system cabin, and the wind power generation mechanism and the solar power generation system are located on the power generation system platform; a nano-triboelectric generator is installed inside the power generation combined system cabin; ballast water tanks capable of independent water injection and drainage are distributed around the power generation combined system cabin, and water pumps are connected to the ballast water tanks; a truss structure is connected to the bottom of the power generation combined system cabin, and pontoons are installed below the truss structure.

[0007] The principle and beneficial effects of this invention are as follows: The working principle of this invention is as follows: The power generation system platform is set on top of the power generation combination system hull, forming the main body of the offshore floating platform. The wind power generation mechanism uses the stable high wind speed at sea to drive the blades to rotate and convert wind energy into electrical energy. The solar power generation system uses the unobstructed solar radiation at sea to convert light energy into electrical energy. The nano-triboelectric generator set set in the power generation combination system hull uses the overall swaying of the platform caused by wave fluctuations to convert the mechanical energy of the waves into electrical energy. The three power generation methods complement each other in the time dimension. Wind power generation is affected by wind speed changes, solar power generation is affected by day and night and weather, and nano-triboelectric generators can work continuously around the clock by utilizing wave fluctuations. The three together ensure the continuity and stability of power supply; the power generation combination system hull is distributed around the hull. Ballast tanks increase the overall weight of the system by filling them with water, thus increasing the platform's draft and causing it to sink. Conversely, draining the water reduces the overall weight, allowing the platform to float. In extreme sea conditions such as typhoons, filling the ballast tanks lowers the platform's center of gravity and reduces wave loads. In normal sea conditions, draining the water allows the platform to float, increasing wave excitation and improving the efficiency of the nano-triboelectric generators. The truss structure connecting the bottom of the power generation system's hull is a triangular stabilizing structure that transfers the hull load to the lower pontoons. The pontoons provide buoyancy support for the entire platform system, and the vibrations generated by the pontoons with wave motion are transmitted to the hull via the truss structure, further enhancing the mechanical excitation of the nano-triboelectric generators within the hull.

[0008] Compared to existing technologies, this invention integrates the nano-triboelectric generator unit inside the power generation system's cabin, utilizing the platform's overall swaying with the waves to drive power generation. This replaces the hydraulic transmission structure used in existing oscillating float-type or oscillating body-type wave energy power generation devices, eliminating complex mechanical transmission components such as hydraulic rods and motors, reducing equipment failure rates and offshore maintenance costs. Simultaneously, the built-in cabin of the nano-triboelectric generator unit avoids corrosion and biofouling problems caused by direct exposure to the seawater environment, extending the equipment's service life. In existing technologies, wave energy power generation modules are arranged around the platform's hull, with floats and hydraulic rods in direct contact with seawater. Seals and hydraulic components require frequent maintenance due to seawater corrosion. In contrast, this invention encloses the nano-triboelectric generator unit inside the cabin, ensuring a stable operating environment and significantly extending maintenance cycles. Secondly, ballast water tanks are distributed around the power generation system's cabin and can be independently filled and drained, enabling the entire platform to actively rise and sink. This is fundamentally different from existing technologies where ballast water tanks are only located inside wave energy floats or used only for platform dynamic leveling. This invention utilizes ballast water tanks to lower the platform's center of gravity during extreme sea conditions such as typhoons, reducing its wind-exposed area and wave impact, thus enhancing its survivability. During normal sea conditions, water is pumped out to allow the platform to float, increasing its wave-induced motion and improving the power generation efficiency of the nano-triboelectric generator. Third, the bottom of the power generation system's hull employs a composite support structure of truss and pontoons. The truss structure ensures structural rigidity and stability while transmitting wave-induced vibrations from the pontoons to the hull, enhancing the mechanical excitation of the nano-triboelectric generator. The pontoons provide stable buoyancy support. Fourth, the three power generation methods share the same power generation system platform, power generation system hull, and power transmission channel, improving the utilization rate of marine space and infrastructure, reducing unit power generation costs, and compensating for the intermittent nature of wind and solar power with the all-weather characteristics of nano-triboelectric generators. The combined output of the three significantly improves power supply stability.

[0009] Furthermore, the nano-triboelectric generator set is composed of multiple nano-triboelectric generators. Each nano-triboelectric generator includes a top cover plate, an upper electrode pair, an electrode support plate, a polytetrafluoroethylene (PTFE) ball, a lower electrode pair, and a bottom plate. A through-hole is formed on the electrode support plate. The diameter of the PTFE ball is larger than the thickness of the electrode support plate, and the upper and lower sides of the ball protrude from the upper and lower surfaces of the electrode support plate, respectively. The upper and lower electrode pairs are located on the upper and lower sides of the electrode support plate, respectively. Under the action of wave action, the PTFE ball rolls back and forth within the cavity, alternately contacting and rubbing against the upper and lower electrode pairs to generate charge. Using the PTFE ball as the friction medium, under the platform swaying caused by wave action, the PTFE ball rolls freely within the cavity and alternately contacts and rubs against the electrode pairs on the upper and lower sides. Based on the principles of triboelectric charging and electrostatic induction, the low-frequency mechanical energy of the waves is directly converted into electrical energy, eliminating the need for hydraulic rods and gears. The mechanical transmission components, such as bearings, are simple in structure, reliable in operation, and low in maintenance cost, making them particularly suitable for long-term operation in complex marine environments. Both the upper and lower electrode pairs are made of conductive metal materials and are connected to the batteries in the battery compartment via electrode leads, transferring the generated charge to the batteries for storage. The symmetrical arrangement of the upper and lower electrode pairs allows the PTFE ball to simultaneously rub against both electrodes during a single reciprocating roll, improving energy conversion efficiency per unit volume. PTFE material possesses excellent dielectric properties, chemical stability, and corrosion resistance, ensuring stable charge output over a long period as a friction layer material. The enclosed stacked structure, protected by the upper and lower cover plates of the nano-triboelectric generator, effectively prevents short circuits and corrosion caused by seawater moisture intrusion. This single nano-triboelectric generator has a compact structure and small thickness, facilitating multi-layer stacking to form a nano-triboelectric generator set. Clustered arrangement significantly increases the total output power, meeting the practical needs of offshore power generation platforms.

[0010] Furthermore, the solar power generation system includes multiple solar power generation devices. Each solar power generation device includes a grid-shaped fixed frame composed of horizontal and vertical I-beams, solar panels fixed to the fixed frame, a vertical rotating motor, a horizontal rotating motor, and a hydraulic lifting device. The vertical rotating motor drives the solar panel to pitch around a horizontal axis via gear transmission, and the horizontal rotating motor drives the solar panel to rotate around a vertical axis via gear transmission. The hydraulic lifting device includes a hydraulic support rod and a lifting column. A hydraulic pump supplies oil to the hydraulic lifting device, driving the lifting column to raise or lower the solar panel vertically. The grid-shaped fixed frame composed of horizontal and vertical I-beams has high structural rigidity and strong load-bearing capacity, capable of withstanding strong wind loads at sea and the weight of the solar panels. The number of solar panels on the frame can be flexibly increased or decreased according to power generation needs, facilitating large-scale expansion. The vertical rotating motor and the horizontal rotating motor... The machine drives the solar panels to rotate vertically and horizontally via gear transmission. It can adjust the panel orientation based on the real-time azimuth and altitude angles of the sun, ensuring the panels are always at the optimal angle for direct sunlight, significantly improving solar power generation efficiency. The gear transmission features high transmission precision, strong load-bearing capacity, and smooth operation, making it suitable for driving large offshore solar panel arrays. A hydraulic lifting device raises and lowers the solar panels vertically. Under normal sea conditions, the panels are raised to ensure ventilation, heat dissipation, and power generation space. In extreme weather conditions such as typhoons, the dual rotating motors rotate the panels to a horizontal position and lower them close to the power generation system platform, significantly reducing the wind-exposed area and wave impact, thus mitigating the risk of damage to the solar power generation device from typhoons. This structure achieves a dual-mode working mechanism: enhancing efficiency under normal operating conditions and providing protection under extreme conditions, improving power generation efficiency while enhancing the equipment's survivability in harsh marine environments.

[0011] Furthermore, the power generation system is divided into three levels: the first level, the second level, and the third level. The first level houses the lifting mechanism for the nano-triboelectric generator and the solar power generation system. The second level houses the transformer, battery room, central control room, inverter, and diesel generator set. The third level houses the water pumps for filling and draining the ballast tanks and the nano-triboelectric generator set. Power generation, power conversion, control, energy storage, emergency power supply, and ballast regulation functions are arranged vertically in zones, each relatively independent, with equipment operating without interference, facilitating equipment installation, maintenance, and management. The lifting mechanism for the nano-triboelectric generator and the solar power generation system is located close to the power generation system platform for easy operation and maintenance of the solar panels. The nano-triboelectric generator generates electricity using the swaying motion of the upper level caused by waves. The second level centrally houses the transformer, battery room, central control room, inverter, and diesel generator set, forming the power generation system. The transformation and control core layer features a central control room for unified monitoring and dispatching of all platform power generation equipment. The centralized arrangement of transformers and inverters shortens power cable connections. Diesel generator sets, serving as an emergency power supply system, are located in the middle safety zone, allowing for rapid startup to ensure power supply to critical loads in case of main power equipment failure. The third layer houses water pumps and nano-triboelectric generators for filling and draining ballast tanks. The proximity of the water pumps to the ballast tanks around the hull shortens the filling and draining pipelines and reduces water flow resistance. The nano-triboelectric generators, positioned at the bottom layer, utilize the platform's maximum sway to enhance power generation efficiency. Distributed arrangement of nano-triboelectric generators on the first and third layers allows for simultaneous utilization of wave vibration energy at different heights, improving hull space utilization and total power output. Furthermore, placing heavy equipment such as transformers, batteries, and water pumps on the second and third layers helps lower the platform's overall center of gravity, enhancing its stability and seaworthiness at sea.

[0012] Furthermore, the ballast water tank is connected to a water pump. The water pump's inlet pipe is equipped with an inlet valve and an inlet pressure gauge, and the water pump's outlet pipe is equipped with an outlet valve and an outlet pressure gauge. The water pump and valves control the injection and drainage of the ballast water tank. The water pump provides the power source for the injection and drainage of the ballast water tank, and seawater is injected and discharged through the inlet and outlet pipes, respectively. The inlet valve on the inlet pipe controls the opening and closing of the injection channel and the flow rate, and the inlet pressure gauge monitors the seawater pressure on the inlet side in real time. Similarly, the outlet valve on the outlet pipe controls the opening and closing of the drainage channel and the flow rate, and the outlet pressure gauge monitors the pipeline pressure on the outlet side in real time. Through the coordination of valves and pressure gauges, the injection and discharge volumes of each ballast tank can be precisely controlled, thereby accurately adjusting the overall draft and buoyancy of the platform. In extreme sea conditions such as typhoons, the inlet valves can be quickly opened to inject water into the ballast tanks to cause the platform to sink and avoid danger. In normal sea conditions, the outlet valves can be opened to discharge the ballast water, causing the platform to float and resume power generation. Each ballast tank can be independently controlled for injection and discharge. By adjusting the water distribution in different ballast tanks, the platform tilt can be corrected and its level posture maintained. The pressure gauges monitor the pipeline pressure data in real time, which can promptly detect pipeline blockages, leaks, or pump malfunctions, ensuring the safe and reliable operation of the ballast tank regulation system.

[0013] Furthermore, a ring of anti-collision airbags is installed outside the ballast tank, and distance sensors are installed at the four corners of the power generation system platform. These distance sensors are electrically connected to the anti-collision airbags. The ring of anti-collision airbags outside the ballast tank forms a circular buffer barrier around the platform. The distance sensors at the four corners of the power generation system platform can monitor the surrounding sea area in 360 degrees, eliminating blind spots. When the distance sensors detect a moving object on the sea surface (such as a yawing vessel or floating debris) entering a preset warning distance, the anti-collision airbags are immediately triggered to inflate, deploying before an impact occurs to form an elastic buffer. The system effectively mitigates the impact force of ships or floating objects on the platform, reducing the risk of damage to platform equipment and property loss. Compared with traditional fixed anti-collision structures, this protection mechanism, which combines active detection and active activation, has a fast response speed and good buffering effect. Normally, the airbags are inflated and fixed outside the ballast tank, without affecting the platform's normal navigation and operation. In extreme weather such as typhoons or when a collision risk is detected, the protection is automatically activated, balancing the convenience of daily operation with safety under extreme conditions. At the same time, the real-time monitoring data from the distance sensing sensors can be linked with the central control room to achieve early warning and remote alarm of collision risks, buying time for emergency response on the platform.

[0014] Furthermore, the wind power generation mechanism includes a nacelle, with a drone landing pad on top. The landing pad is equipped with a wireless charging device and a robotic arm charging device. The wireless charging device connects to the battery inside the nacelle via an electromagnetic coil embedded in the landing pad. The robotic arm charging device charges the drones, which have a socket-type interface, via a charging arm. The drone landing pad on top of the nacelle fully utilizes the unused space above the nacelle, eliminating the need for additional space on the power generation platform and achieving efficient use of platform space. Maritime drones commonly face problems of insufficient battery life and lack of charging facilities during long-distance flights. This landing pad provides drones with a temporary docking and charging point at sea. Drones can travel along a pre-set route to the platform to charge and continue their missions, significantly expanding the operational scope of maritime drones. Range and endurance: The helipad is equipped with both wireless charging and robotic arm charging devices. The wireless charging device connects to the battery in the cabin via an electromagnetic coil buried under the helipad, providing contactless automatic charging for drones equipped with wireless charging receivers. This eliminates the need for mechanical docking and is highly automated. The robotic arm charging device provides wired charging for drones with socket-type interfaces via a charging interface on the charging arm, compatible with various interface types. This dual-mode charging design covers the charging needs of different types of drones and has a wide range of applications. In addition, the helipad can also serve as a fixed docking point for platform patrol drones. After charging, the drones can conduct regular and fixed-point patrols of the power generation platform, promptly detect equipment anomalies and safety hazards, and remotely call for support, improving the platform's operational efficiency and safety assurance capabilities.

[0015] Furthermore, the power generation system platform is equipped with insulator protective shells in all four directions, and three-phase insulator joints are installed inside the insulator protective shells. The presence of insulator protective shells and three-phase insulator joints in all four directions allows the platform to be electrically connected to adjacent platforms from any direction, making network formation flexible and convenient. The insulator protective shells can be closed when not in use to prevent corrosion of the insulator joints by seawater and salt spray; they can be opened for line connection when network formation is needed, effectively protecting the reliability of electrical connection components. Multiple multi-energy combined integrated power generation platform systems, as power generation units, are interconnected through three-phase transmission lines to form a power generation unit matrix, realizing multi-platform interconnection. Combined power generation significantly increases the total power output of each power generation unit, creating advantages of large-scale power generation. At the same time, the complementarity of power generation among multiple units further enhances the continuity and stability of power supply. The power generated by the power generation unit matrix is ​​uniformly stepped up and then transmitted to the shore substation and grid through long-distance transmission lines, avoiding the duplication of investment in separate transmission facilities for each power generation unit and significantly reducing the transmission cost per unit of power generation. The matrix arrangement allows the power generation platform group to be located far from the coast in deep-sea areas, fully developing the abundant wind, solar and wave energy resources in deep sea areas, adapting to the complex deep-sea environment, and expanding the development space of marine renewable energy.

[0016] Furthermore, in this invention, the industrial control computer configured in the central control room serves as the unified control core of the entire power generation platform system. It centrally schedules and coordinates the wind power generation mechanism, solar power generation system, and nano-triboelectric generator sets. Based on real-time weather conditions and the output status of each power generation unit, it optimizes the allocation of power generation load, achieving efficient and coordinated operation of multi-energy complementarity and avoiding scheduling incoordination problems caused by independent and decentralized control of each power generation device. The industrial control computer monitors power generation and transmission in real time, collects operating data such as voltage, current, and power of each power generation unit, promptly detects equipment faults, locates the fault point, and issues alarm signals, improving the intelligent level of platform operation and maintenance. During typhoons… In extreme weather conditions, the industrial control computer automatically triggers a linkage protection mechanism based on meteorological monitoring data. On the one hand, it controls the ballast water tank to inject water into the tank, causing the platform to sink as a whole, lowering the center of gravity and reducing wave load. On the other hand, it controls the solar power generation device to descend and retract close to the platform, reducing the wind-exposed area. The two protection actions are executed in tandem, realizing the integrated linkage of platform attitude adjustment and equipment retraction protection. Compared with manual operation or independent protection of each subsystem, the response speed is faster and the protection is more comprehensive. The industrial control computer also has data processing, safety early warning and communication transmission functions, which can remotely transmit platform operation data to the shore-based monitoring center, realizing unmanned operation and remote maintenance of the offshore power generation platform.

[0017] Furthermore, the output end of the diesel generator set is connected to the power supply lines of the lighting system, fire-fighting equipment, and communication equipment to serve as an emergency power supply system; when the wind power generation mechanism, solar power generation system, and nano-friction generator set cannot work properly or the battery power is insufficient, the diesel generator set starts and supplies power to the lighting system, fire-fighting equipment, and communication equipment.

Detailed Implementation

[0020] Example 1 The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the multi-energy combined integrated power generation platform system of this embodiment includes a power generation system platform 13 and a power generation combined system cabin 8. The power generation system platform 13 is located on top of the power generation combined system cabin 8, and a wind power generation mechanism and a solar power generation system 6 are installed on the power generation system platform 13. A nano-triboelectric generator set is installed inside the power generation combined system cabin 8. Ballast water tanks that can be independently filled and drained are distributed around the power generation combined system cabin 8, and the ballast water tanks can be independently filled and drained to adjust the buoyancy of the platform. A truss structure is connected to the bottom of the power generation combined system cabin 8, and a pontoon 12 is installed below the truss structure.

[0022] The wind power generation system includes a tower 5, a nacelle 4, a blade hub 3, and wind turbine blades 1. The lower end of the tower 5 is mounted on the power generation system platform 13, and the upper end of the tower 5 is connected to the nacelle 4. The central axis of the blade hub 3 is horizontally positioned, and three wind turbine blades 1 are fixed to the outer shell of the blade hub 3 in a ring-shaped evenly distributed manner around its central axis. The nacelle 4 houses a generator, transformer, voltage regulator, and battery. The wind on the sea surface drives the wind turbine blades 1 to rotate, generating mechanical energy. This mechanical energy is transferred through the blade hub 3 to the generator in the nacelle 4, where it is converted into electrical energy. The transformer and voltage regulator then adjust the electrical energy to a stable voltage for subsequent power transmission.

[0023] like Figure 2As shown, a drone landing pad 2 is located on the top of the cabin 4. Landing pad 2 is surrounded by landing pad signal lights 21 and monitoring cameras 19. The landing pad signal lights 21 are used to accurately locate the landing pad position when drones land at night, and the monitoring cameras 19 are used to observe the take-off and landing status of the drones. The drone landing pad 2 has two charging modes: one is an electromagnetic coil buried under the landing pad, which is connected to the battery in the cabin 4 via a charging line 22 to provide wireless charging for drones 16 equipped with wireless charging receivers; the other is a charging arm 24 located at one end of the landing pad, with a charging arm charging interface 23 to provide wired charging for drones with socket-type interfaces. The drone landing pad 2 also includes drone parking positions 18 and drone charging interfaces 17.

[0024] like Figure 1 and Figure 9 As shown, the solar power generation system 6 is distributed in a 4×4 structure on the power generation system platform 13, with 4 horizontal and 4 vertical rows, totaling 16 solar power generation devices. Each solar power generation device includes a solar panel, a grid-shaped fixed frame composed of horizontal I-beams 71 and vertical I-beams 72, a solar panel mounting bracket 70, a support base 74, a vertical rotating motor 82, a horizontal rotating motor 84, and a hydraulic lifting device. Individual solar panels 87 are mounted on the grid-shaped fixed frame via the solar panel mounting bracket 70. Each power generation device holds 6 individual solar panels 87, but the number of individual solar panels 87 can be increased on the horizontal and vertical I-beams according to power generation needs. Support bases 74 are located below the horizontal I-beams 71 and vertical I-beams 72, and the support bases 74 are fixed by fixing bolts 73. Component a75 is welded to the support base 74. Component a75 is equipped with gear a77, which meshes with gear b81. A vertical rotary motor 82 drives gear b81 to rotate, which in turn drives gear a77 to rotate. This, via component a75, causes the solar panel to tilt and rotate around a horizontal axis. The vertical rotary motor 82 is mounted on a motor base a83. Gear c78 meshes with gear d79. Gear c78 is mounted on a lifting support column 80, and gear d79 is mounted on a horizontal rotary motor 84. The horizontal rotary motor 84 drives gear d79 to rotate, which in turn drives gear c78 to rotate, causing the solar panel to rotate around a vertical axis. The horizontal rotary motor 84 is mounted on a motor base b85. The vertical and horizontal rotary motors 82 and 84 allow the solar panel to rotate 360 ​​degrees horizontally and vertically, adjusting the angle of the solar panel facing the sunlight according to the intensity of sunlight. The hydraulic lifting device connects the hydraulic support rod 33 and the lifting column 80. The hydraulic pump 86 is connected to the hydraulic lifting device, and the hydraulic pump 86 supplies oil to cause the lifting column 80 to rise or fall vertically. Figure 16As shown, during extreme weather such as typhoons, the solar panels are first placed horizontally by two rotating motors, and then the lifting support column 80 is lowered by a hydraulic lifting device to lower the solar panels to a position close to the power generation system platform 13, thereby reducing the damage of typhoons to the solar power generation device and wind resistance.

[0025] like Figure 3 As shown, the power generation system compartment 8 is divided into three layers: the first layer (28), the second layer (29), and the third layer (30). Independent ballast water tanks are distributed around the compartment, each capable of independent water storage and release. The outermost layer of the ballast water tanks is a collision protection airbag.

[0026] like Figure 4 As shown, the first layer 28 of the power generation system mainly houses the lifting mechanism room and the nano-triboelectric generator sets. The lifting mechanism room contains the lifting mechanism of the solar power generation system and hydraulic pumps 34, with each set of two hydraulic pumps 34. The first layer 28 of the power generation system is enclosed by the first-layer bulkhead 26 of the power generation system, and its interior is divided into multiple independent spaces by longitudinally and transversely combined partitions 32, ensuring that the equipment operates without interference. The nano-triboelectric generator sets 31 within the first layer 28 of the power generation system are located in the nano-triboelectric generator compartment, which is divided into nine independent modules. Figure 7 As shown, a single module consists of a 6×9 nanometer triboelectric generator assembly 57, each nanometer triboelectric generator assembly is divided into 10 layers, and each layer is a single nanometer triboelectric generator 60.

[0027] like Figure 5As shown, the second layer 29 of the power generation system mainly consists of a transformer room, a battery room, a central control room 37, inverters, an air conditioning chiller unit 41, a diesel generator set 43, a second-layer bulkhead 44, and a partition plate 122 within the second layer. The central control room 37, located in the middle of the second layer, is the core of the entire system, controlling the operation of the wind power generation mechanism, the solar power generation system 6, and the nano-triboelectric generator set, and monitoring power generation and transmission. Transformer 35 (No. 1) and Transformer 40 (No. 2) are located on the left and right sides of the central control room 37, respectively. These two transformers can operate simultaneously or serve as backups for each other, acting as step-up transformers. Battery room 36 (No. 1) and Battery room 39 (No. 2) are located behind the transformers to store the charge generated by the equipment. Inverter 38 (No. 1) and Inverter 42 (No. 2) are located before and after the central control room 37, respectively, to convert the generated direct current (DC) into alternating current (AC), preparing for subsequent long-distance power transmission. Two diesel generator sets 43 are installed next to the inverter room as an independent emergency power supply system. When other power generation equipment fails to work properly or the battery storage capacity is insufficient, the diesel generator sets 43 can automatically start in a very short time to supply power to the lighting system, fire-fighting equipment, communication equipment, etc., ensuring smooth external communication and basic power supply in emergency situations.

[0028] like Figure 10 As shown, the transformer mainly consists of a low-voltage bushing 88, a high-voltage bushing 89, a transformer housing 90, and heat sinks 91. Figure 11 As shown, the battery pack includes a battery pack housing 92, a front cover 93, and a base 94. The front cover 93 can be opened 90 degrees, allowing the battery 95 to be removed via the battery mounting base 96 and its sliding rail 97 for easy replacement. The front cover 93 is made of transparent glass, facilitating observation of the battery's operating status. Figure 12 As shown, the air conditioning chiller unit 41 consists of a top fan 98, a condenser bracket 99, an upper cover 100, a V-shaped condenser 101, and a condenser water tank 102. The air conditioning chiller unit 41 circulates cold air supplied by an air conditioner, dissipating heat to the outside through a refrigeration cycle, thus lowering the overall system temperature and achieving constant temperature control. Figure 13 As shown, the main unit of the central control room 37 includes a main unit cabinet shell 103, a front glass door 104, an industrial control computer 105, and an industrial control computer base 106. The industrial control computer 105 is used for controlling power generation, power conversion and storage, data acquisition and processing, equipment monitoring and control, safety early warning, communication and data transmission, etc.

[0029] like Figure 6As shown, the third layer 30 of the power generation system is enclosed by the third-layer bulkhead 47, and internally divided into multiple spaces by partitions 46 within the third layer. The bottom is the third-layer floor 55. The third layer 30 is the pump placement area for the ballast water tanks, with a total of 12 pumps evenly distributed around the perimeter, each pump connected to a corresponding ballast water tank. The remaining space on the third layer is used to house the nano-triboelectric generator sets 45 within the third layer of the power generation system, totaling 12 sets. Figure 8 As shown, the nano-triboelectric generator unit 45 in the third layer of the power generation system adopts a 6×6 nano-triboelectric generator assembly 68. Ballast water pumps fill and drain the ballast water tanks around the platform. Figure 14 As shown, the cross-section 107 of the ballast water tank reveals its structure. A water pump motor 53 drives the water pump. The inlet pipe 50 is equipped with an inlet valve 49 and an inlet pressure gauge 51, while the outlet pipe 54 is equipped with an outlet valve 52 and an outlet pressure gauge 48. Water is pumped into the ballast water tank to submerge the platform; the greater the water volume, the deeper the platform's draft and the greater the submersion. Conversely, water is pumped out of the tank to float the platform; the greater the water displacement, the greater the platform's float. During extreme weather events such as typhoons, the ballast water tank is filled with seawater to submerge the platform system, lowering the overall center of gravity of the platform and reducing the significant swaying caused by the typhoon.

[0030] like Figure 7 and Figure 8As shown, a single nano-triboelectric generator 60 includes a nano-triboelectric generator top cover plate 61, an upper electrode pair 62, a polytetrafluoroethylene (PTFE) ball 63, an electrode support plate 64, a lower electrode pair 65, and a nano-triboelectric generator bottom plate 66. The electrode support plate 64 has a through-hole cavity. The diameter of the PTFE ball 63 is larger than the thickness of the electrode support plate 64. The upper and lower sides of the ball protrude from the upper and lower surfaces of the electrode support plate 64, respectively. The PTFE ball 63 is placed within the cavity. The upper electrode pair 62 and the lower electrode pair 65 are located on the upper and lower sides of the electrode support plate 64, respectively, and are encapsulated by the nano-triboelectric generator top cover plate 61 and the nano-triboelectric generator bottom plate 66. Under the action of sea waves, the entire device oscillates rhythmically. The PTFE ball 63 rolls back and forth within the cavity, alternately contacting and rubbing against the upper electrode pair 62 and the lower electrode pair 65, generating charge transfer under the action of micro-mechanical friction. Each individual nano-triboelectric generator 60 generates a small amount of charge. These are combined into clusters to form a nano-triboelectric generator protection group 59, which in turn are combined to form a nano-triboelectric generator assembly. The upper electrode pair 62 and the lower electrode pair 65 are both made of conductive metal and are connected to the battery pack via electrode leads. The generated charge is ultimately stored in the battery pack. The first layer is encapsulated using a nano-triboelectric generator protective housing 58 and a 6×9 nano-triboelectric generator protective housing cover 56, while the third layer is encapsulated using a nano-triboelectric generator protective housing 69 and a 6×6 nano-triboelectric generator protective housing cover 67.

[0031] like Figure 1 As shown, below the bottom of the power generation system hull 8, a truss structure is formed by welding or bolting vertical rods 9, diagonal rods 10, and crossbeams 11, creating a triangular stable structure. The lower end of the truss structure is fixedly connected to the pontoons 12 via flanges or welding. Three pontoons 12 form a group, with a total of four groups, forming a stable buoyancy support structure.

[0032] like Figure 1 and Figure 15 As shown, a ring of anti-collision airbags 7 is installed outside the ballast tank. Distance sensors 15 are installed at the four corners of the power generation system platform 13. When a moving target object enters the preset warning distance range, the distance sensors 15 trigger the anti-collision airbags 7 to inflate, forming a protective airbag ring outside the ballast tank to mitigate the impact force of the ship. The anti-collision airbag activation state 108 is as follows. Figure 15 As shown.

[0033] like Figure 17As shown, insulator protective shells 14 are installed in all four directions of the power generation system platform 13. The insulator protective shells 14 can be opened horizontally to the left and right, and three-phase insulator connectors 109 are installed inside. When not in use, the insulator protective shells 14 are closed for protection; they are opened when matrix combined power generation is required. Figure 18 As shown, the entire power generation system is considered as a single power generation unit. Every two power generation units are connected by insulator joints 109 via three-phase transmission lines 111, and the three-phase transmission lines 111 are secured by transmission line insulation fixing straps 110. Figure 19 As shown, nine power generation units are arranged in a 3×3 configuration to form a power generation unit matrix, and then interconnected by three-phase transmission lines 111, so that the power supply of each power generation unit is connected together. Figure 20 As shown, the power generation unit matrix is ​​set at sea level 120. The alternating current generated by the power generation unit matrix is ​​stepped up by a transformer and connected to the shore via a long-distance transmission line 119. After passing through towers 117, disconnect switches 114, busbars 115, etc., it is finally transmitted to the shore substation 116, where it is stepped up again and the electricity is fed into the national power grid. The shore slope 118, seabed 121, seawater section 112, and seabed section 113 are shown in the figure. Figure 20 As shown.

[0034] like Figure 21 and Figure 22 As shown, the circuit system of a single power generation system converts and stores the electrical energy generated by the wind power generator, solar power system 6, and nano-triboelectric generator through transformers, inverters, and batteries before transmitting it externally. After the power generation units are combined into a power generation matrix, the circuit systems of each power generation unit are interconnected, and the power is uniformly boosted and transmitted over long distances.

[0035] The working process of this embodiment is as follows: Under normal sea conditions, the ballast tank is drained to make the platform float. The wind power generation mechanism generates electricity using offshore wind energy. The solar power generation system 6 adjusts the angle of the solar panels according to the sun's position to generate photovoltaic power. The nano-triboelectric generator sets generate electricity using the platform's swaying caused by wave fluctuations. The three types of electrical energy are converted by transformers and inverters and stored in batteries or directly transmitted to the outside. Under extreme sea conditions such as typhoons, the industrial control computer 105 in the central control room 37 controls the ballast tank to fill with water to make the platform sink and lower its center of gravity. At the same time, it controls the rotating motor and hydraulic lifting device of the solar power generation device to place the solar panels horizontally and lower them to the platform position, reducing wind resistance and wave impact. When the distance sensor 15 detects the approach of a ship, it triggers the anti-collision airbag 7 to activate, protecting the platform from impact. Multiple power generation units can be connected through a three-phase transmission line 111 to form a power generation unit matrix. After unified voltage boosting, the power is transmitted over a long distance to the shore substation 116 and connected to the power grid.
