Description

Technical Field

[0001] The present invention belongs to the technical field of distributed energy systems, and specifically relates to a multi-energy coupling intelligent power generation device that integrates wind power, photovoltaic power and wave energy. Background Art

[0002] With the accelerated transition of the global energy structure toward a low-carbon economy and the advancement of my country's "dual carbon" strategy, distributed energy systems in marine areas, such as the ocean, are facing higher demands. In scenarios such as islands and offshore platforms, traditional single-energy power supply systems, such as independent wind, photovoltaic, or wave power generation, are limited by high intermittency, insufficient energy storage technology, and poor environmental adaptability. They suffer from high power outage rates and low energy utilization. For example, single wind or photovoltaic systems are susceptible to offshore weather, while wave energy devices face challenges such as low energy capture efficiency and mechanical structures susceptible to erosion by the marine environment, making it difficult to meet the stable energy supply needs of off-grid areas and offshore platforms.

[0003] Although multi-energy coupling technology has been explored both domestically and internationally, existing solutions have significant drawbacks in their application in the seawater field. For example, the wind-wave coupling platform of the Xiamen Offshore Power Generation Research Institute has improved power generation efficiency, but the complexity of the system leads to a high failure rate and difficulty in maintenance, and marine salt spray corrosion seriously affects the life of the equipment. The large-scale offshore wind turbines of CSIC Offshore Engineering are far from land, with high maintenance costs and insufficient reliability, and their performance is affected by long-term erosion by the marine environment. For example, the deep-sea wind-wave complementary system of Pelagic Power AS in Norway has a complex structure and high cost, with heavy component loads and high sealing requirements. GHT's tidal energy and wave energy combined device has problems such as low coupling efficiency and significant impact on the marine ecology. In addition, the power output drops significantly when there is no wind, making it difficult to provide stable power supply.

[0004] The core bottlenecks of existing technologies in the seawater field are concentrated in three aspects: first, the mechanical structure is complex and costly. The simple combination of multi-source energy collection units leads to high system redundancy. The structure needs to be further strengthened in the complex marine environment, which pushes up development and maintenance costs. Second, the coupling energy acquisition efficiency is low. The traditional transmission mechanism has insufficient conversion efficiency for multi-degree-of-freedom motion of waves (such as longitudinal sway, vertical sway, and pitch), and the motor control accuracy is insufficient, resulting in large energy loss. Third, the system stability is poor. Electrical faults such as overvoltage and overcurrent are prone to occur during the multi-energy coupling process. At the same time, marine environmental factors such as salt spray and moisture accelerate equipment corrosion, leading to an increase in failure rate.

[0005] Therefore, there is an urgent need for an efficient multi-energy coupling system with wave energy generation units as the core, integrating wind power and photovoltaic energy. Through innovative energy capture mechanisms, intelligent transmission structures and marine environment adaptability designs, it can break through the intermittent limitations and efficiency bottlenecks of traditional technologies and meet the low-carbon, stable and efficient energy supply needs in water scenarios such as oceans and islands. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a multi-energy coupling intelligent power generation device that integrates wind power, photovoltaic power and wave energy. By integrating the three power generation units in the frame, and utilizing the dual synergistic mechanism of vertical swing and swing power generation of the wave power generation unit, the planetary reduction transmission of the wind power generation unit and the intelligent tracking control of the photovoltaic power generation unit, it breaks through the intermittent, efficiency and stability bottlenecks of traditional technologies in the seawater field, and realizes low-carbon, high-efficiency and stable energy supply in scenarios such as oceans and islands.

[0007] In order to achieve the above-mentioned purpose of the invention, the technical solutions adopted are as follows:

[0008] The present invention discloses a multi-energy coupling intelligent power generation device integrating wind power, photovoltaic power generation and wave power, comprising a frame and a wind power generation unit, a photovoltaic power generation unit and a wave power generation unit integrated on the frame, wherein the wave power generation unit comprises: a vertical swing power generation unit, comprising: a float, for capturing the multi-freedom motion of waves and converting it into three-dimensional space swing; an articulated seat, fixedly connected to the float, and provided with a multi-directional articulated shaft; a connecting rod assembly, with both ends respectively articulated to the multi-directional articulated shaft of the articulated seat and a bevel gear pair, for converting the three-dimensional space swing of the float into a plane swing and transmitting it to the bevel gear pair; the bevel gear pair is connected to the vertical swing generator for connecting The planar swing of the rod assembly is converted into rotational motion and transmitted to the vertical swing generator; the vertical swing generator is used to convert the rotational motion of the bevel gear pair into electrical energy; the swing power generation unit includes: a swing guide plate, one end of which is hinged to the frame through a universal joint and a spur rack is fixed on it; a sliding power generation platform, which is sleeved on the swing guide plate and hinged to the vertical swing power generation unit through the other end. The sliding power generation platform is provided with a spur gear connected to the input shaft of the swing generator. The spur gear is engaged with the spur rack and is used to rotate along the spur rack when the float swings in three-dimensional space, driving the sliding power generation platform to make linear motion along the swing guide plate, and then driving the generator to generate electricity through the spur gear.

[0009] This invention integrates wind, photovoltaic, and wave energy generation units within a single rack, blending these three energy sources and leveraging the coordinated operation of these units to achieve energy complementarity. In water areas like oceans and islands, when wind or photovoltaic power generation is insufficient due to weather, the wave energy generation units can provide continuous power, resolving the intermittent nature of traditional single-energy systems, significantly improving power supply stability, and reducing power outages.

[0010] In addition, the frame is made of high-strength corrosion-resistant steel to adapt to complex marine environments such as seawater erosion and wind and wave impact, extending the life of the equipment and reducing maintenance frequency; the single pile structure integrates three power generation units to reduce system redundancy. Compared with existing multi-energy coupling technology, it reduces structural complexity and failure rate, and maintenance costs are significantly reduced.

[0011] In terms of energy conversion, the bevel gear pair and spur gear-spur rack transmission structure efficiently convert the float swing energy into rotational or linear motion. Combined with the guide rail and slider guide mechanism, it ensures transmission accuracy, reduces energy loss, and solves the bottleneck of low coupling efficiency in traditional technology.

[0012] In this invention, the multi-degree-of-freedom wave motion includes longitudinal oscillation along the wave propagation direction, vertical oscillation perpendicular to the water surface, and pitching about the transverse axis. These motions drive the float to oscillate in three dimensions. By articulating the connecting rod assembly with an articulated seat equipped with a multi-directional articulated axis, the present invention converts the float's three-dimensional oscillation into planar oscillation in different directions. This is then converted into rotational motion via a bevel gear pair to drive the generator. Compared to traditional single-articulated axis designs, this structure can adapt to the float's three-dimensional oscillation, avoids the energy loss caused by unidirectional articulation, and significantly improves wave energy utilization.

[0013] Furthermore, when the float swings three-dimensionally due to sway, heave, and pitch, it inevitably causes the heave power generation unit to undergo attitude changes such as tilt, pitch, and yaw. To this end, the swing power generation unit utilizes a universal joint to construct an adaptive transmission structure: the swing guide plate is hinged to the frame via the universal joint, and the sliding power generation platform is also hinged to the heave power generation unit via the universal joint. Leveraging the multi-degree-of-freedom nature of the universal joint, which can rotate about mutually perpendicular axes, the swing guide plate and the sliding power generation platform can rotate synchronously in real time with the heave power generation unit's attitude changes, ensuring that the spur rack and spur gear always precisely mesh. This design enables the sliding power generation platform to smoothly move linearly along the swing guide plate during the three-dimensional swing of the float, driving the spur gear to rotate on the spur rack to generate electricity. This avoids the problems of meshing failure and transmission jamming caused by attitude changes in traditional rigid connections. By dynamically adapting the universal joint to the heave power generation unit's attitude changes, the system achieves continuous and efficient capture of wave energy, significantly improving its adaptability and reliability in complex marine environments.

[0014] The core innovation of this invention lies in the innovative construction of a dual synergistic power generation path through the three-dimensional oscillation mechanism of the float. When the float undergoes three-dimensional oscillations—surge, heave, and pitch—the heave and swing power generation units do not operate independently, but rather respond simultaneously and generate electricity in tandem. When the heave component is significant, the up-and-down motion of the float, through a multi-directionally articulated connecting rod assembly and bevel gear pair, prioritizes driving the heave generator for efficient power generation. Simultaneously, the swing power generation unit also operates. Its spur rack meshes with the spur gear, and as the float swings, it drives the sliding power generation platform in linear motion, driving the swing generator to generate electricity. When oscillation and pitch dominate, the swing power generation unit's energy conversion becomes the primary output, while the heave power generation unit continues to operate, converting residual heave energy into electricity. This dual-mode synergistic mechanism adjusts the operating priorities of the two power generation units in real time based on the varying states of the float's oscillation, enabling both automatic switching to match the dominant oscillation component and synchronized power generation. This completely eliminates the energy loss inherent in the traditional single-path approach and enables full-dimensional capture of wave energy, regardless of the float's three-dimensional oscillation, significantly improving utilization.

[0015] Furthermore, the multi-directional articulated shaft includes: an articulated base shaft, which is fixedly connected to the float along the normal direction of the float surface; a first-direction articulated shaft and a second-direction articulated shaft, which are integrated at the end of the articulated base shaft, and the two are orthogonal and perpendicular to the articulated base shaft; the connecting rod assembly includes a first connecting rod assembly and a second connecting rod assembly, one end of which is respectively articulated to the first-direction articulated shaft and the second-direction articulated shaft, and the other end is respectively connected to the bevel gear pair, for converting the three-dimensional spatial swing of the float into the swing of the connecting rod assembly.

[0016] In the present invention, a multi-directional articulated shaft cooperates with a double-link assembly through orthogonally arranged first and second directional articulated shafts to decompose the three-dimensional spatial swing of the float's longitudinal, vertical, and pitch motions into swings within two orthogonal planes (e.g., decomposing the composite motion of vertical and pitch motions), which are then transmitted to the bevel gear pair via the first and second link assemblies. This design breaks through the limitation of traditional single articulated shafts that can only capture the energy of swings in a single direction, responding to the float's multi-degree-of-freedom motion in all dimensions. It ensures that the swing energy in each dimension is efficiently transmitted to the bevel gear pair through the corresponding link assembly, avoiding energy loss caused by the inability to fully decompose the three-dimensional motion components, significantly improving wave energy utilization, and resolving the industry's pain point of insufficient energy conversion in multi-degree-of-freedom motion from the mechanical transmission level.

[0017] Furthermore, the first connecting rod assembly includes an active rod and a first transmission rod, and the second connecting rod assembly includes a driven rod and a second transmission rod. One end of the active rod and the driven rod are respectively hinged to the first direction hinge shaft and the second direction hinge shaft, and the other ends are respectively hinged to the first transmission rod and the second transmission rod through a pin shaft. The other ends of the first transmission rod and the second transmission rod are respectively fixedly connected to the bevel gear pair.

[0018] In the present invention, the active rod and the driven rod are respectively hinged on the orthogonal hinge shafts and the distribution shaft and the transmission rod are connected to the bevel gear pair through the structural design. The three-dimensional swing energy of the float can be stably decomposed into two-way planar motion and efficiently transmitted and summarized, thereby solving the problem of insufficient response of the traditional single-link structure to complex swings and improving the stability and energy conversion efficiency of the wave energy transmission system.

[0019] Furthermore, the bevel gear pair adopts two groups of orthogonal meshing structures, each group includes two mutually orthogonal bevel gears; the two bevel gears of the first group of bevel gear pairs are fixedly connected to the first transmission rod and the second transmission rod respectively, and the second group of bevel gear pairs is transmission-connected to the input shaft of the vertical swing generator.

[0020] Specifically, the first bevel gear pair consists of two orthogonally meshing bevel gears, with the first and second transmission rods fixedly connected to the two bevel gears in this group. The active rod of the first connecting rod assembly and the driven rod of the second connecting rod assembly are hinged at one end to the first and second articulated axes of the multi-directional hinge shaft, respectively, and connected to the first and second transmission rods via pins at the other ends. This decomposes the three-dimensional oscillation of the float into planar kinetic energy in different directions, which is then transmitted to the first bevel gear pair. This avoids the energy loss caused by traditional single-direction articulation and significantly improves energy utilization.

[0021] After the first bevel gear pair completes the initial energy conversion, the second bevel gear pair takes over and plays a key role. This pair, also composed of two orthogonally meshing bevel gears, aggregates the planar kinetic energy from the first pair in different directions into rotational motion, converting it into a speed and torque suitable for the helical generator, driving it to generate efficient power.

[0022] Two sets of bevel gear pairs relay the power, and through the precise meshing characteristics of the gear pairs, the transmission ratio is automatically adjusted based on changes in wave strength and frequency. When wave energy is strong, the speed is reduced and the torque is increased to fully utilize the energy; when wave energy is weak, the speed is increased to ensure power generation efficiency. This achieves effective energy aggregation and conversion and intelligently adapts to actual operating conditions. In this way, regardless of how wave conditions change, the wave power generation unit can maintain high energy conversion efficiency and power generation stability.

[0023] Furthermore, the vertical swing power generation unit also includes a vertically arranged first guide rail and a first slider fixed to the float, and the first slider is slidably engaged with the first guide rail to drive the float to perform linear motion relative to the first guide rail.

[0024] Furthermore, the vertical swing power generation unit further includes a top cover arranged above the base plate, the base plate, and a guide rail frame arranged below the base plate, and the guide rail is fixed to the guide rail frame.

[0025] Furthermore, a second guide rail is provided on the other side of the swing guide plate corresponding to the spur rack, and the sliding power generation platform is fixed with a second slider that slides with the second guide rail, which is used to synchronously drive the second slider to slide on the second guide rail when the spur gear of the sliding power generation platform rotates along the spur rack.

[0026] In the present invention, a second guide rail is provided on the swing guide plate and cooperates with the second slider of the sliding power generation platform. When the spur gear rotates along the spur rack, the guiding effect of the guide rail-slider ensures that the sliding power generation platform can perform non-deflected linear motion along the limit plate, thereby avoiding gear meshing failure or jamming caused by motion offset, improving the transmission accuracy and stability of the spur gear and the spur rack, thereby reducing energy loss and ensuring continuous and efficient power generation of the swing generator.

[0027] Furthermore, return springs are arranged in parallel on both sides of the swing guide plate, one end of the return spring is arranged on the swing guide plate, and the other end is arranged on the sliding power generation platform.

[0028] Specifically, two sets of return springs are symmetrically arranged parallel to each other on either side of the swinging guide plate, with each set of springs connecting the swinging guide plate to the sliding power generation platform at either end. This design, through the symmetrical dual return springs, achieves a dual purpose when the sliding power generation platform is driven back and forth by waves: first, it helps the platform quickly reset, ensuring that the spur gear and spur rack are always engaged, thus preventing interruptions in wave energy capture; second, it offsets the off-center load of the reciprocating motion, reducing mechanical wear, improving the structural stability of the swinging power generation unit, and extending its service life.

[0029] Furthermore, the wind power generation unit includes: blades, fixed to the blade frame, used to capture wind energy and convert it into rotational kinetic energy; the blade frame, fixed to the blade frame base, providing rotational support for the blades; the blade frame base, connected to the box-type planetary reducer, used to transfer the rotational kinetic energy of the blades to the box-type planetary reducer; the box-type planetary reducer includes: a bottom support plate and an upper cover, the upper cover is arranged on the bottom support plate to form a closed cavity; the planetary frame, as a kinetic energy input end, is fixedly connected to the blade frame base, used to drive the planetary gear to revolve around the sun gear with the rotational kinetic energy of the blades; the planetary gear and the sun gear, the planetary gear is arranged on the planetary frame, and is meshed with the outside of the sun gear, and is meshed with the inner gear ring fixed to the inner wall of the upper cover; the sun gear is connected to the input shaft of the wind turbine as the kinetic energy output end, and the deceleration and torque increase transmission is realized through the planetary gear system to drive the wind turbine to generate electricity.

[0030] Furthermore, the photovoltaic power generation unit includes: a base, which serves as an installation basis and supports a dual-axis drive module and a two-axis gimbal; the dual-axis drive module is arranged on the base, including a servo and a metal steering wheel, configured to receive the angle control amount of the intelligent control unit and drive the two-axis gimbal to adjust the angle; the two-axis gimbal is composed of a servo frame rotating around the Y-axis and a servo frame rotating around the X-axis, is arranged above the dual-axis drive module, and is configured to carry the photovoltaic panel and adjust its angle; the photovoltaic panel is mounted on the two-axis gimbal for photoelectric conversion; a photoresistor array is arranged on the photovoltaic panel and is configured to detect light intensity data in different directions; the intelligent control unit adopts MPPT optimization algorithm, Kalman filter algorithm and PID algorithm, and is configured to calculate the angle control amount of the two-axis gimbal in real time based on the light intensity data, and output it to the dual-axis drive module.

[0031] In this invention, the various components of the photovoltaic power generation unit work together to efficiently capture light energy. The base serves as the foundational support structure, stably supporting the dual-axis drive module and two-axis gimbal. The dual-axis drive module, consisting of a servo and a metal steering wheel, receives angle control commands from the intelligent control unit and drives the two-axis gimbal, which consists of a servo frame rotating around the Y and X axes, to adjust the angle of the photovoltaic panel mounted on it. A photoresistor array on the photovoltaic panel's surface detects light intensity data from different directions in real time and transmits it to the intelligent control unit.

[0032] During operation, the photoresistor array continuously monitors the light intensity distribution. The intelligent control unit dynamically tracks the maximum power point of illumination using an MPPT optimization algorithm. It also utilizes a Kalman filter to suppress high-frequency noise generated by ambient light fluctuations, ensuring the accuracy of illumination data. Based on the processed illumination information, the intelligent control unit calculates the azimuth and pitch angle adjustments of the photovoltaic panel using a PID algorithm, generating control commands to drive the dual-axis drive module. The servo, driven by a metal steering wheel, drives the two-axis gimbal to adjust the photovoltaic panel's posture in real time, ensuring it always faces the sun at the optimal angle. Through an automated "detection-calculation-adjustment" process, the entire system achieves dynamic and efficient capture of light energy, significantly improving the photovoltaic panel's photoelectric conversion efficiency and power generation stability under varying lighting conditions, thereby reducing energy waste.

[0033] The beneficial effects of the present invention compared to the prior art are as follows:

[0034] 1) This invention utilizes a three-dimensional buoy swing mechanism to create a dual, coordinated power generation path. The heave and swing generators work in real time, coordinated by wave components. When heave is significant, the undulation of the buoy drives the heave generator via a multi-directional articulated connecting rod and bevel gear pair, while the spur gear-rack drive of the swing generator synchronously drives the swing generator. When swell / pitching dominates, the swing generator becomes the primary output, while the heave generator continuously converts residual energy. This mechanism enables automatic switching and synchronous power generation, capturing wave energy in all dimensions and significantly improving utilization compared to traditional single-path approaches.

[0035] 2) The present invention converts the three-dimensional swing of the float into planar kinetic energy through a multi-directional articulated shaft and connecting rod assembly, and drives the generator through a bevel gear pair, avoiding the energy loss of a traditional single articulated shaft; at the same time, the swing power generation unit is hinged to the frame and the vertical swing power generation unit through a universal joint, and the multi-degree-of-freedom rotation characteristics are used to ensure precise gear engagement, avoid transmission jamming of rigid connections, and enable the swing power generation unit to follow the dynamic posture of the vertical swing unit in real time, thereby improving the system's adaptability and reliability to complex marine environments.

[0036] 3) In the existing technology, single wind energy / photovoltaic systems are greatly affected by weather, and the independent power generation efficiency of wave energy devices is low. However, the present invention integrates wind power, photovoltaic power generation units, and wave energy generation units into a rack, and utilizes a multi-energy synergistic and complementary mechanism. When wind power or photovoltaic power generation is insufficient, wave energy can provide sustainable power supply, significantly reducing the power supply interruption rate in complex scenarios and solving the problem of strong intermittent power generation in traditional single energy systems.

DETAILED DESCRIPTION

[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other unless there is a conflict.

[0064] like Figure 1-Figure 7As shown, the present invention discloses a multi-energy coupling intelligent power generation device integrating wind power, photovoltaic power and wave power, including a frame 47 and a wind power generation unit 43, a photovoltaic power generation unit 44 and a wave power generation unit 45 integrated on the frame 47, and the wave power generation unit 45 includes: a vertical swing power generation unit, including: a float 1, used to capture the multi-degree-of-freedom motion of waves and convert it into three-dimensional space swing; an articulated seat, fixed to the float 1, provided with a multi-directional articulated shaft; a connecting rod assembly, with both ends respectively articulated to the multi-directional articulated shaft and a bevel gear pair of the articulated seat, used to convert the three-dimensional space swing of the float 1 into a plane swing and transmit it to the bevel gear pair; the bevel gear pair is connected to the vertical swing generator 10 in transmission connection, used to convert the plane swing of the connecting rod assembly into a plane swing. The vertical swing generator 10 is used to convert the rotational motion of the bevel gear pair into electrical energy; the vertical swing generator 10 is used to convert the rotational motion of the bevel gear pair into electrical energy; the swing power generation unit includes: a swing guide plate 17, one end of which is hinged to the frame 47 through a universal joint 25, and a spur rack 19 is fixed on it; a sliding power generation platform 18, which is sleeved on the swing guide plate 17 and hinged to the vertical swing power generation unit through the other end, and a spur gear 20 connected to the input shaft of the swing generator 21 is provided on the sliding power generation platform 18. The spur gear 20 is engaged with the spur rack 19 and is used to rotate along the spur rack 19 when the float 1 swings in three-dimensional space, driving the sliding power generation platform 18 to make linear motion along the swing guide plate 17, and then driving the generator to generate electricity through the spur gear 20.

[0065] The present invention integrates wind power generation unit 43, photovoltaic power generation unit 44, and wave power generation unit 45 via a frame 47, integrating these three energy sources and achieving energy complementarity through the coordinated operation of the various power generation units. When wind power generation unit 43 or photovoltaic power generation unit 44 is experiencing insufficient power generation due to weather conditions, wave power generation unit 45 can provide continuous power, resolving the intermittent nature of traditional single-energy systems, significantly improving power supply stability, and reducing power outage rates.

[0066] Frame 47's structural design utilizes high-strength, corrosion-resistant steel, making it resistant to complex marine environments such as seawater erosion and wind and wave impacts. This effectively extends the equipment's service life and reduces maintenance requirements. Its monopile structure integrates three power generation units, reducing system redundancy, structural complexity, and failure rate compared to existing multi-energy coupling technologies, significantly lowering maintenance costs.

[0067] In terms of energy conversion, the bevel gear pair and spur gear 20-spur rack 19 transmission structure of the wave energy generation unit 45 efficiently converts the swing energy of the float 1 into rotational or linear motion. This combined guidance mechanism, consisting of the first guide rail 14 and first slider 15 of the heave power generation unit, and the second guide rail 22 and second slider 23 of the swing power generation unit, ensures transmission accuracy and reduces energy loss, successfully overcoming the bottleneck of low coupling efficiency in traditional technologies.

[0068] In the present invention, the multi-degree-of-freedom wave motion includes longitudinal oscillation along the wave propagation direction, vertical oscillation perpendicular to the water surface, and pitching about the transverse axis. These motions drive the float 1 to produce three-dimensional oscillation. By articulating the connecting rod assembly with an articulated seat having a multi-directional articulated axis, the present invention converts the three-dimensional oscillation into planar oscillation in different directions. This is then aggregated into rotational motion via a bevel gear pair, driving the heave generator 10 to generate electricity. Compared to traditional single-articulated axis designs, this structure can adapt to the three-dimensional oscillation of the float 1, avoiding the energy loss caused by unidirectional articulation and significantly improving the utilization of wave energy.

[0069] Furthermore, the three-dimensional oscillations of float 1 (surge, heave, and pitch) cause the heave power generation unit to undergo changes in attitude, such as tilt, pitch, and yaw. To this end, the swing power generation unit utilizes a universal joint 25 to construct an adaptive transmission structure: the swing guide plate 17 is hinged to the frame 1 via the universal joint 25, and the sliding power generation platform 18 is also hinged to the heave power generation unit via the universal joint 25. Leveraging the multi-degree-of-freedom nature of the universal joint 25, which can rotate about mutually perpendicular axes, the swing guide plate 17 and the sliding power generation platform 18 can rotate synchronously with the heave power generation unit's attitude changes in real time, ensuring that the spur rack 19 and spur gear 20 are always precisely engaged. This design enables the sliding power generation platform 18 to move smoothly in a straight line along the swinging guide plate 17 when the float 1 swings in three dimensions, driving the spur gear 20 to rotate on the spur rack 19 to generate electricity, avoiding problems such as meshing failure and transmission jamming caused by posture changes in traditional rigid connections. Through the dynamic adaptation of the universal joint 25 to the posture changes of the vertical swing power generation unit, the continuous and efficient capture of wave energy is achieved, significantly improving the adaptability and reliability of the system to complex marine environments.

[0070] More importantly, the core innovation of the present invention lies in the innovative construction of a dual synergistic power generation path through the three-dimensional swing mechanism of float 1: when float 1 undergoes three-dimensional swings such as longitudinal swing, heaving swing, and pitch roll, the heaving swing power generation unit and the swing power generation unit do not work independently of each other, but respond simultaneously and generate electricity in coordination. When the heaving component is more significant, the up and down movement of float 1, through the multi-directional articulated connecting rod assembly and bevel gear pair, preferentially drives the heaving generator 10 to generate electricity efficiently; at the same time, the swing power generation unit is also in play. The spur rack 19 of the swing power generation unit engages with the spur gear 20, and as the float 1 swings, it drives the sliding power generation platform 18 to move linearly, driving the swing generator 21 to generate electricity. When the longitudinal swing, pitch roll and other components dominate, the energy conversion of the swing power generation unit becomes the main output, but the heaving power generation unit continues to operate, converting the residual heaving energy into electrical energy. This dual-mode collaborative mechanism can adjust the working focus of the two power generation units in real time according to the different swing states of float 1. It can not only realize automatic switching to match the dominant swing component, but also achieve synchronous power generation, completely making up for the energy loss defects of the traditional single path. No matter how float 1 swings in three dimensions, it can capture wave energy in all dimensions and greatly improve utilization rate.

[0071] like Figures 8-10 As shown, in a preferred embodiment, the multi-directional articulated shaft includes: an articulated base shaft 2, fixedly connected to the float 1 along the normal direction of the surface of the float 1; a first-direction articulated shaft 3 and a second-direction articulated shaft 4, integrated at the end of the articulated base shaft 2, and the two are orthogonal and perpendicular to the articulated base shaft 2; a connecting rod assembly includes a first connecting rod assembly and a second connecting rod assembly, one end of which is respectively articulated to the first-direction articulated shaft 3 and the second-direction articulated shaft 4, and the other end is respectively connected to a bevel gear pair, for converting the three-dimensional spatial swing of the float 1 into the swing of the connecting rod assembly. Specifically, the first connecting rod assembly includes an active rod 5 and a first transmission rod 7, and the second connecting rod assembly includes a driven rod 6 and a second transmission rod 8. One end of the active rod 5 and the driven rod 6 is respectively articulated to the first-direction articulated shaft 3 and the second-direction articulated shaft 4, and the other end is respectively articulated to the first transmission rod 7 and the second transmission rod 8 through a pin 26. The other end of the first transmission rod 7 and the second transmission rod 8 is respectively fixed to the bevel gear pair.

[0072] In this embodiment, a multi-directional articulated shaft cooperates with a double-link assembly (a first link assembly and a second link assembly) via orthogonally arranged first-direction articulated shafts 3 and 4 to decompose the three-dimensional spatial swing of the float 1, namely, vertical, vertical, and vertical motion, into swings within two orthogonal planes (e.g., decomposing the combined motion of vertical and vertical motion). This swing is then transmitted via the first link assembly (active rod 5, first transmission rod 7) and the second link assembly (driven rod 6, second transmission rod 8) to a bevel gear pair consisting of a bevel gear 9. This design overcomes the limitation of a traditional single articulated shaft that can only capture energy from swings in a single direction. It responds to the multi-degree-of-freedom motion of the float 1 in all dimensions, ensuring that the swing energy in each dimension is efficiently transmitted to the bevel gear pair through the corresponding link assembly, avoiding energy loss caused by the inability to fully decompose the three-dimensional motion components, significantly improving wave energy utilization, and resolving the industry pain point of insufficient energy conversion from multi-degree-of-freedom motion at the mechanical transmission level.

[0073] In addition, the active rod 5 and the driven rod 6 are respectively hinged to the first direction hinge shaft 3 and the second direction hinge shaft 4 in the orthogonal directions, and the distribution shaft 26 is connected to the first transmission rod 7 and the second transmission rod 8 through the structural design of the bevel gear pair. The three-dimensional swing energy of the float 1 can be stably decomposed into two-way planar motion and efficiently transmitted and summarized, solving the problem of insufficient response of the traditional single-link structure to complex swings, and improving the stability and energy conversion efficiency of the wave energy transmission system.

[0074] like Figure 9 and Figure 10 As shown, in an embodiment of the present invention, the bevel gear pair adopts two groups of orthogonal meshing structures, each group includes two mutually orthogonal bevel gears 9; the two bevel gears 9 of the first group of bevel gear pairs are fixedly connected to the first transmission rod 7 and the second transmission rod 8 respectively, and the second group of bevel gear pairs is transmission-connected to the input shaft of the vertical oscillation generator 10.

[0075] Specifically, the first bevel gear pair consists of two orthogonally meshing bevel gears 9, with a first transmission rod 7 and a second transmission rod 8 fixedly connected to the two bevel gears 9. The active rod 5 of the first connecting rod assembly and the driven rod 6 of the second connecting rod assembly are hinged at one end to the first and second articulated axes 3 and 4 of the multi-directional articulated shaft, respectively, and connected to the first and second transmission rods 7 and 8 via pins 26 at their other ends. This decomposes the three-dimensional oscillation of the float 1 into planar kinetic energy in different directions, which is then transmitted to the first bevel gear pair. This avoids the energy loss caused by traditional unidirectional articulation and significantly improves energy utilization.

[0076] After the first bevel gear pair completes the initial energy conversion, the second bevel gear pair takes over and plays a key role. This pair, also composed of two orthogonally meshing bevel gears 9, aggregates the planar kinetic energy from the first pair in different directions into rotational motion, converting it into a speed and torque suitable for the heave generator 10, driving it to generate electricity efficiently.

[0077] Two sets of bevel gear pairs relay the power, and through the precise meshing characteristics of the gear pairs, the transmission ratio is automatically adjusted based on changes in wave strength and frequency. When wave energy is strong, the speed is reduced and the torque is increased to fully utilize the energy; when wave energy is weak, the speed is increased to ensure power generation efficiency. This achieves effective energy aggregation and conversion and intelligently adapts to actual operating conditions. In this way, regardless of how wave conditions change, the wave power generation unit can maintain high energy conversion efficiency and power generation stability.

[0078] like Figure 8 、 Figure 9 and Figure 11 As shown, in a preferred embodiment, the vertical swing power generation unit further includes a vertically arranged first guide rail 14 and a first slider 15 fixed to the float 1, and the first slider 15 slides in cooperation with the first guide rail 14 to drive the float 1 to perform linear motion relative to the first guide rail 14.

[0079] like Figure 7 and Figure 8As shown, in a preferred embodiment, a hollow boss 16 is provided on the outside of the float 1, which significantly optimizes the performance of the heave power generation unit. Specifically, the first guide rail 14 vertically passes through the interior of the hollow boss 16, and together with the first slider 15 fixed to the inner side of the boss by bolts or welding, forms a guide structure, which effectively limits the lateral deviation of the float 1 under the action of waves and ensures its stable linear motion along the guide rail. At the same time, the hollow boss 16 provides protection for the first slider 15, reducing the risk of seawater corrosion and collision with floating objects. In addition, this structure optimizes the layout of the heave power generation unit and provides reasonable installation space for components such as the articulated seat and the connecting rod assembly, so that the float 1 can more efficiently convert energy into mechanical energy when capturing the multi-degree-of-freedom movement of waves, thereby improving the energy conversion efficiency and operational reliability of the wave energy power generation unit 45.

[0080] In this embodiment of the present invention, the heave power generation unit further includes a top cover 11 disposed above a base plate 12, the base plate 12, and a guide rail frame 13 disposed below the base plate 12. A first guide rail 14 is fixed to the guide rail frame 13. The top cover 11 and the base plate 12 cooperate to form a semi-enclosed protective space, which effectively isolates the salt spray, water vapor, and floating debris in the external marine environment. This provides reliable protection for the critical internal bevel gear pair and heave power generator 10, preventing them from rusting, wearing, and other problems caused by long-term exposure to harsh environments, thereby significantly extending the overall service life of the heave power generation unit.

[0081] Guide rail frame 13 is made of high-strength, corrosion-resistant steel. Its robust structural design not only provides reliable mounting support for first guide rail 14, ensuring its vertical and stable placement, allowing precise linear motion of first slider 15 on float 1 along it, but also indirectly ensures the operational stability of the bevel gear pair and heave generator 10. Under the constant impact of waves, guide rail frame 13 strengthens the overall structural strength of the heave generator unit, ensuring the relative stability of its components, and laying a solid foundation for the stable and efficient operation of wave energy generator 45.

[0082] like Figure 12 、 Figure 14 and Figure 15 As shown, in the swing power generation unit of wave energy power generation unit 45, to further ensure transmission accuracy, in a preferred embodiment, a second guide rail 22 is provided on the other side of the swing guide plate 17 corresponding to the spur rack 19. A second slider 23 is fixedly mounted on the sliding power generation platform 18, which slides in engagement with the second guide rail 22. When the buoy 1 is subjected to three-dimensional swinging due to the action of waves, the spur gear 20 on the sliding power generation platform 18 rotates along the spur rack 19, and the second slider 23 slides synchronously on the second guide rail 22.

[0083] This guide structure, through the cooperation of the second guide rail 22 and the second slider 23, effectively constrains the motion trajectory of the sliding power generation platform 18, ensuring that it always moves in a straight line along the swinging guide plate 17 without deviation. This prevents the meshing failure or jamming of the spur gear 20 and the spur rack 19 due to deviation, significantly improving transmission accuracy and stability. This design significantly reduces energy loss, ensures the continuous and efficient operation of the swinging generator 21, and helps the wave energy generation unit 45 operate stably in complex marine environments.

[0084] In a preferred embodiment, return springs 24 are arranged in parallel on both sides of the swing guide plate 17 , one end of the return spring 24 is fixed to the swing guide plate 17 , and the other end is connected to the sliding power generation platform 18 .

[0085] like Figure 13 As shown, in a specific embodiment, two sets of return springs 24 are symmetrically arranged in parallel on both sides of the swing guide plate 17, with the two ends of each set of return springs 24 respectively connected to the swing guide plate 17 and the sliding power generation platform 18. This design, through the symmetrical distribution of the two sets of return springs 24, plays a dual role when the sliding power generation platform 18 is driven by waves to reciprocate. First, the return springs 24 provide a rebound force to help the sliding power generation platform 18 quickly reset, ensuring that the spur gear 20 and the spur rack 19 remain engaged at all times, avoiding interruptions in wave energy capture due to motion jams. Second, the symmetrically arranged springs effectively offset the off-center load during reciprocating motion, reducing contact wear between mechanical components such as the spur gear 20 and the spur rack 19, thereby improving the structural stability of the swing power generation unit assembly and extending its service life.

[0086] like Figure 1 、 Figures 16-21 As shown, in a preferred embodiment, the wind power generation unit 43 includes: blades 27, fixed to the blade frame 28, for capturing wind energy and converting it into rotational kinetic energy; the blade frame 28, fixed to the blade frame base 29, for providing rotational support for the blades 27; the blade frame base 29, connected to the box-type planetary reducer 30, for transmitting the rotational kinetic energy of the blades 27 to the box-type planetary reducer 30.

[0087] In addition, the box-type planetary reducer 30 includes: a bottom support plate 32 and an upper cover 31, the upper cover 31 is arranged on the bottom support plate 32 to form a closed cavity; a planetary carrier 33, which is fixedly connected to the blade frame base 29 as a kinetic energy input end, and is used to drive the planetary gear 34 to revolve around the sun gear 35 with the rotational kinetic energy of the blade 27; the planetary gear 34 and the sun gear 35, the planetary gear 34 is arranged on the planetary carrier 33, and is engaged with the sun gear 35 externally, and is engaged with the ring gear 36 fixed to the inner wall of the upper cover 31; the sun gear 35 is connected to the input shaft of the wind turbine as a kinetic energy output end, and realizes deceleration and torque increase transmission through the planetary gear system to drive the wind turbine to generate electricity.

[0088] The wind power generation unit 43 operates as follows: blades 27 are fixed to blade holders 28. When wind blows on blades 27, their unique airfoil design enables blades 27 to capture wind energy and convert it into rotational kinetic energy. Blade holders 28 are fixed to blade holder bases 29, providing stable rotational support for blades 27 and enabling smooth transfer of rotational kinetic energy to blade holder bases 29. Blade holder bases 29 are connected to box-type planetary reducers 30, which transfer the rotational kinetic energy to the box-type planetary reducers 30. Box-type planetary reducers 30 consist of a closed cavity formed by a bottom support plate 32 and an upper cover 31. Planetary carriers 33, serving as the kinetic energy input, are fixedly connected to blade holder bases 29, driving planetary gears 34 to revolve around sun gears 35. Planetary gears 34 mesh externally with sun gears 35 and internally with ring gears 36 fixed to the inner wall of upper cover 31. The planetary gear train achieves speed reduction and torque increase. Ultimately, sun gear 35, serving as the kinetic energy output, transfers the processed kinetic energy to the wind turbine input shaft, driving the wind turbine to generate electricity.

[0089] like Figure 1 、 Figure 22 and Figure 23 As shown, in a preferred embodiment, the photovoltaic power generation unit 44 includes: a base 37, which serves as an installation base for supporting a dual-axis drive module and a two-axis gimbal; the dual-axis drive module is arranged on the base 37, including a servo 38 and a metal steering wheel 39, configured to receive the angle control amount of the intelligent control unit and drive the two-axis gimbal to adjust the angle; the two-axis gimbal is composed of a servo frame 40 rotating around the Y axis and a servo frame 41 rotating around the X axis, arranged above the dual-axis drive module, configured to carry a photovoltaic panel 42 and adjust its angle; the photovoltaic panel 42 is mounted on the two-axis gimbal for realizing photoelectric conversion; a photoresistor array is arranged on the photovoltaic panel 42, configured to detect light intensity data in different directions; the intelligent control unit adopts an MPPT optimization algorithm, a Kalman filter algorithm and a PID algorithm, and is configured to calculate the angle control amount of the two-axis gimbal in real time based on the light intensity data, and output it to the dual-axis drive module.

[0090] In this embodiment, the various components of the photovoltaic power generation unit 44 work together to efficiently capture light energy. The base 37 serves as the foundational support structure, stably supporting the dual-axis drive module and the two-axis gimbal. The servo 38 in the dual-axis drive module receives angle control commands from the intelligent control unit and, through a metal steering wheel 39, drives the two-axis gimbal, consisting of a Y-axis rotating servo frame 40 and an X-axis rotating servo frame 41, thereby adjusting the angle of the photovoltaic panel 42 mounted thereon. The photoresistor array on the surface of the photovoltaic panel 42 detects light intensity data from different directions in real time and transmits it to the intelligent control unit.

[0091] The photovoltaic power generation unit 44 operates as follows: the photoresistor array on the surface of the photovoltaic panel 42 continuously monitors the light intensity distribution in different directions and transmits this data in real time to the intelligent control unit. The intelligent control unit first dynamically tracks the maximum power point of illumination using an MPPT optimization algorithm, while simultaneously employing a Kalman filter to suppress high-frequency noise generated by ambient light fluctuations, ensuring accurate light data. Based on this processed light information, the intelligent control unit then uses a PID algorithm to accurately calculate the azimuth and pitch angle adjustments of the photovoltaic panel 42, generating control instructions that are output to the dual-axis drive module.

[0092] The dual-axis drive module is mounted on a base 37, which provides a secure support and ensures stable operation. Upon receiving control commands, the servo 38 in the dual-axis drive module transmits power through a metal steering wheel 39, driving a two-axis gimbal consisting of a servo frame 40 rotating around the Y axis and a servo frame 41 rotating around the X axis. These two servos work in tandem to adjust the position of the photovoltaic panels 42 mounted on them in real time, ensuring they always face the sun at the optimal angle.

[0093] The entire workflow is a continuous, dynamic process. As external lighting conditions change in real time, the photovoltaic power generation unit 44 continuously repeats the automated process of "detection-calculation-adjustment", achieving dynamic and efficient capture of light energy, significantly improving the photoelectric conversion efficiency and power generation stability of the photovoltaic panel 42 under different lighting conditions, and reducing energy waste.

[0094] like Figure 3-Figure 4 As shown, in this embodiment of the present invention, a wind power generation unit 43 is mounted atop a frame 47, fully utilizing high-altitude wind resources. Four mounting platforms 46 are connected around the perimeter of the frame 47 to form a mid-level structure, with two photovoltaic power generation units 44 positioned diagonally on each platform. These units, equipped with a dual-axis drive module and a two-axis gimbal, detect light intensity using a photoresistor array. The intelligent control unit utilizes MPPT optimization, Kalman filtering, and PID algorithms to automatically adjust the angle of the photovoltaic panels 42 for efficient photoelectric conversion.

[0095] A wave energy power generation unit 45 is fixed below the mounting platform 46, and comprises four swing power generation units and one vertical swing power generation unit. The four swing power generation units are arranged in the front, back, left, and right directions of each mounting platform 46, with one end hinged to the bottom of the platform via a universal joint, and the other end hinged to the vertical swing power generation unit via a universal joint. The swing generator 21 is driven by a spur rack-spur gear transmission to generate electricity; the vertical swing power generation unit drives the vertical swing generator 10 via an articulated seat, a connecting rod assembly, and a bevel gear pair. When the float swings in three dimensions, the two power generation units work together to generate electricity synchronously. In addition, the frame 47 is provided with two buoys 48 on each side of the outer side through a clamping portion to provide buoyancy support to ensure the stable floating of the device.

[0096] Through the above-mentioned layout, the present invention enables the three power generation units to form a composite power generation structure on the frame 47: the photovoltaic power generation unit 44 and the wave power generation unit 45 are closely coordinated with the installation platform 46, and combined with the top wind power generation unit 43 to achieve multi-energy coordinated collection of light energy, wind energy and wave energy, significantly improving the energy collection efficiency in the marine environment.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
