The buoy body floats on the water surface. The solar power generation component is located on the upper side of the buoy body. The wave power generation component is located on the lower side of the buoy body. The tidal current power generation component can rotate relative to the buoy body around a vertical axis and can move vertically relative to the buoy body. The wave power generation component, driven vertically by the tidal current power generation component, enables the floating component to move vertically to drive the first power generation component to generate electricity. The energy storage component stores electrical energy. This self-powered buoy, utilizing ocean current energy, can achieve the integrated use of solar, tidal, and wave energy, improve self-powering efficiency, and adapt to multi-directional tidal changes.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To address the technical problem that self-generating buoys can only utilize one or two of the following marine energy resources—wind, solar, and wave energy—resulting in low utilization and power generation efficiency, this invention provides a marine buoy power generation device. This device utilizes at least one photovoltaic element 310, a wind power generation component 400, and at least one wave power generation component 500, all electrically connected to a battery, on the buoy. This allows for the simultaneous utilization and conversion of wind, solar, and wave energy resources from seawater into stored electrical energy. Furthermore, the photovoltaic element 310 has a first state of being deployed relative to the buoy 100 and a second state of being folded relative to the buoy 100, which enhances the photovoltaic panel's resistance to wind and waves, thereby improving the stability and continuity of power generation. This results in high utilization and high power generation efficiency of marine energy.

[0021] Please see Figure 1 , Figures 1 to 3This is a schematic diagram of the structure of a marine buoy power generation device according to an embodiment of the present invention. The marine buoy power generation device includes: a buoy 100, at least one battery, a photovoltaic power generation module 300, a wind power generation module 400, and at least one wave power generation module 500. The battery is connected to the buoy 100. The photovoltaic power generation module 300 includes at least one photovoltaic element 310, which is movably connected to the battery and has a first state of being unfolded after sliding away from the buoy 100 and a second state of being folded after sliding closer to the buoy 100. The photovoltaic element 310 is electrically connected to the battery. The wind power generation module 400 is connected to the buoy 100 and electrically connected to the battery. The wave power generation module 500 is connected to the buoy 100 and electrically connected to the battery.

[0022] Compared to existing technologies, this device, by equipping the buoy with at least one photovoltaic element 310, a wind power generation component 400, and at least one wave power generation component 500, all electrically connected to a battery, can simultaneously utilize wind, solar, and wave energy resources from seawater and convert them into electrical energy for storage. Furthermore, the photovoltaic element 310 has a first state of unfolding relative to the buoy 100 after sliding away from it, and a second state of folding relative to the buoy 100 after sliding closer to it. This enhances the photovoltaic panel's resistance to wind and waves, thereby improving the stability and continuity of power generation. It boasts high utilization of ocean energy and high power generation efficiency, solving the technical problem in existing technologies where self-generating buoys can only utilize one or two of wind, solar, and wave energy resources, resulting in low utilization of ocean energy and low power generation efficiency.

[0023] Furthermore, the float 100 here is a common and readily available sealed shell on the market, with a large volume and capable of floating on the sea surface. The float 100 here is a conventional configuration known to those skilled in the art, and will not be described in detail here.

[0024] In some embodiments, the float 100 is an elliptical sphere with a hollow interior and a good waterproof sealing structure, which will not be described in detail here.

[0025] In some embodiments, there are multiple batteries, all of which are built into the float 100 for storing electrical energy.

[0026] In some embodiments, multiple batteries are arranged in an array and electrically connected. The multiple batteries have built-in floats 100, which can lower the overall center of gravity of the power generation device and give the device good anti-tipping ability.

[0027] In some embodiments, the float 100 of this device is also equipped with a voltage regulator, a transformer and an electrical connection unit. The voltage regulator, transformer and electrical connection unit, together with the photovoltaic component 310, the wind power generation component 400 and the wave power generation component 500, are used to achieve the stability of electrical energy conversion. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0028] In this embodiment, the photovoltaic element 310 is movably connected to the float 100 and can rotate relative to the float 100 about the first direction or the second direction as the axis, and the first direction and the second direction are perpendicular to each other.

[0029] The photovoltaic component 310 can also rotate relative to the float 100 as a whole around the first or second direction as an axis, thereby improving the device's resistance to wind and waves and its ability to prevent tipping.

[0030] Furthermore, the first direction here is the X-axis direction in the planar triangular coordinate system, and the second direction is the Y-axis direction in the planar triangular coordinate system. The X-axis direction and the Y-axis direction are set perpendicular to each other, so that when wind and waves come, the photovoltaic element 310 rotates relative to the floating body 100 around the X-axis direction or the Y-axis direction as the axis, thereby achieving the effect of adaptive balance.

[0031] In one embodiment, such as Figure 3 As shown, the photovoltaic power generation module 300 also includes a support body 320, a first rotating frame 330, and a second rotating frame 340. The support body 320 is used to connect at least one photovoltaic element 310. The first rotating frame 330 is sleeved on the support body 320 and connected to the float 100. The second rotating frame 340 is sleeved on the support body 320 and disposed between the support body 320 and the first rotating frame 330. The second rotating frame 340 is rotatably connected to the first rotating frame 330, so that the second rotating frame 340 rotates relative to the first rotating frame 330 about a first direction as an axis. The support body 320 is rotatably connected to the second rotating frame 340, so that the support body 320 and the photovoltaic element 310 rotate relative to the second rotating frame 340 about a second direction as an axis.

[0032] The first rotating frame 330 and the second rotating frame 340 respectively serve to connect and support the support body 320, at least one photovoltaic element 310 and the float 100.

[0033] Furthermore, the first rotating frame 330 and the second rotating frame 340 are respectively regular polygons.

[0034] In some embodiments, the first rotating frame 330 and the second rotating frame 340 may also be circular, and the maximum diameter of the first rotating frame 330 is greater than the maximum diameter of the second rotating frame 340.

[0035] In some embodiments, the second rotating frame 340 is arranged in the same direction as the support 320, and the second rotating frame 340 is coaxially sleeved on the support 320.

[0036] In this embodiment, as Figure 3 , Figure 4 As shown, the photovoltaic component 310 includes a first photovoltaic panel 311, a second photovoltaic panel 312, and a linear drive unit 313. One end of the first photovoltaic panel 311 is hinged to the side wall of the support body 320, and one end of the second photovoltaic panel 312 is hinged to the other end of the first photovoltaic panel 311. The linear drive unit 313 has a fixed end and a telescopic end. The fixed end of the linear drive unit 313 is hinged to the support body 320, and the telescopic end is hinged to the other end of the second photovoltaic panel 312. It is used to drive the first photovoltaic panel 311 and the second photovoltaic panel 312 to move closer to or away from the side wall of the support body 320.

[0037] The fixed end of the linear drive unit 313 is connected to the side wall of the support body 320, and the telescopic end of the linear drive unit 313 is hinged to the other end of the second photovoltaic panel 312, so that the first photovoltaic panel 311 and the second photovoltaic panel 312 rotate relative to each other, thereby achieving the effect of unfolding or folding.

[0038] Furthermore, the linear drive unit 313 here is a hydraulic cylinder that is common and readily available in the market. The telescopic end of the hydraulic cylinder has a multi-stage structure and is built into the support body 320. The linear drive unit 313 here can also be a push rod motor or a ball screw nut pair structure, which will not be described in detail here.

[0039] Furthermore, the first photovoltaic panel 311 and the second photovoltaic panel 312 are both common and readily available solar power panels on the market, which are conventional settings known to those skilled in the art, and will not be described in detail here.

[0040] In one embodiment, the telescopic end of the linear drive unit 313 in this device includes a central rod, a first slide rod, and at least one second slide rod. The central rod is slidably connected to the fixed end of the linear drive unit 313. The first slide rod and at least one second slide rod are nested and slidably connected to the central rod in sequence. The diameter of the first slide rod and at least one second slide rod gradually decreases in the direction away from the fixed end of the linear drive unit 313, which will not be described in detail here.

[0041] In one embodiment, such as Figure 1 , Figure 3 As shown, the support body 320 is a regular polyhedral column with multiple sidewalls, and there are multiple photovoltaic components 310. The first photovoltaic panel 311 is set one-to-one with the sidewall of the support body 320.

[0042] By arranging multiple photovoltaic elements 310 at intervals on multiple surfaces of the support 320, the utilization rate of solar energy resources can be improved.

[0043] Furthermore, the number of photovoltaic components 310 here is reasonably adjusted according to the size of the first photovoltaic panel 311 and the second photovoltaic panel 312, which will not be elaborated here.

[0044] In some embodiments, the linear drive unit 313 in this device is a central hydraulic pump. The central hydraulic pump has multiple telescopic ends and can simultaneously unfold or fold multiple photovoltaic panels, which will not be described in detail here.

[0045] In one embodiment, such as Figure 1 As shown, the first photovoltaic panel 311 and the second photovoltaic panel 312 are coplanar after unfolding and are set perpendicular to the side wall of the support 320.

[0046] When fully unfolded, the first photovoltaic panel 311 and the second photovoltaic panel 312 are coplanar, which can improve the utilization rate of solar energy resources.

[0047] In this embodiment, as Figure 2 As shown, the wind power generation component 400 includes a first generator 410, a first rotating shaft 420, and at least one blade 430. The first generator 410 is connected to the support body 320 and electrically connected to the battery. The first rotating shaft 420 is arranged vertically and coaxially connected to the rotor end of the generator. At least one blade 430 is connected to the first rotating shaft 420 and is used to drive the rotor end of the generator to rotate. The blade 430 is helical.

[0048] By setting at least one blade 430 on the first rotating shaft 420, when the wind blows the blade 430 to rotate around the first rotating shaft 420 as the axis, it can drive the rotor end of the first generator 410 to rotate, thereby generating electrical energy.

[0049] Furthermore, compared to the vertically arranged blades 430, the spiral blades 430 used in this device have a stronger ability to capture wind energy.

[0050] In some implementations, the number of blades 430 is four, and the four blades 430 are equally spaced along the circumference of the first rotation axis 420.

[0051] In some implementations, the blade 430 is connected to the first rotating shaft 420 by multiple equally spaced support rods.

[0052] In this embodiment, as Figure 1 , Figure 6As shown, the marine buoy power generation device also includes a positioning component 600, a sonar component 700, a hydro-meteorological sensor 800, a radar component 900, and a panoramic camera 1000. The positioning component 600, the sonar component 700, and the hydro-meteorological sensor 800 are respectively connected to the buoy 100 and electrically connected to the battery. The radar component 900 and the panoramic camera 1000 are connected to the farthest end of the first rotating shaft 420 away from the buoy 100 and electrically connected to the battery.

[0053] The buoy's intelligent waterway perception function is composed of a positioning component 600, a sonar component 700, a hydrological and meteorological sensor 800, a radar component 900, and a panoramic camera 1000. The positioning component 600 relies on the Beidou positioning system, the sonar component 700 relies on multi-beam sonar, and the radar component 900 relies on millimeter-wave radar. This constructs a full-element perception network covering both the surface and underwater domains of the waterway, enabling comprehensive and accurate capture of the waterway environment, hydrological conditions, and surrounding targets.

[0054] Furthermore, this application utilizes core technologies such as the extended Kalman filter algorithm, LSTM time series prediction model, and isolated forest algorithm to achieve efficient fusion of multi-source heterogeneous data, early prediction of ship collision risks, accurate identification of abnormal waterway conditions, and real-time early warning of navigation mark position deviations. Simultaneously, it integrates SLAM visual navigation technology, YOLOv7 target obstacle classification algorithm, and genetic algorithm path planning technology to realize the autonomous navigation function of navigation mark equipment, which will not be elaborated here.

[0055] In some embodiments, the device also includes a controller, which is electrically connected to the hydrological and meteorological sensor 800 and the linear drive unit 313. The controller enables the photovoltaic element 310 to automatically determine the timing of photovoltaic panel retraction and deployment based on specific time, environment, lighting conditions, and light intensity signals, thereby achieving automated control of the photovoltaic panel's working state to balance the device's resistance to wind and waves and power generation efficiency. Further details will not be elaborated here.

[0056] Furthermore, the controller is electrically connected to the positioning component 600, sonar component 700, hydrological and meteorological sensor 800, radar component 900, and panoramic camera 1000 to realize automated and intelligent control of the buoy, which will not be elaborated here.

[0057] In one embodiment, such as Figure 5As shown, the interior of the float 100 is hollow and the top is open. The support body 320 passes through the top opening of the float 100 and is connected to the inner wall of the float 100 via the first rotating frame 330. The wave energy generation component 500 includes a second generator 510, a second rotating shaft 520 and an eccentric counterweight 530. The second generator 510 is connected to the inner wall of the float 100 and is electrically connected to the battery. The second rotating shaft 520 is vertically arranged and coaxially connected to the rotor end of the second generator 510. The eccentric counterweight 530 is connected to the second rotating shaft 520 and is used to drive the rotor end of the second generator 510 to rotate.

[0058] By setting multiple second generators 510 inside the float 100, the rotor end of the second generator 510 is driven to rotate by the swaying of the eccentric counterweight 530 under the push of wave energy, thereby realizing the conversion of wave energy into electrical energy.

[0059] Furthermore, the number of wave energy generation components 500 here can be adjusted reasonably according to the specific situation, which will not be elaborated here.

[0060] In some embodiments, the positioning component 600, the sonar component 700, and the hydro-meteorological sensor 800 are respectively connected to the bottom of the float 100.

[0061] In this embodiment, as Figure 1 As shown, the offshore buoy power generation device also includes two underwater propulsion components 1100, which are respectively connected to both sides of the buoy 100 to drive the buoy 100 to move.

[0062] The use of two underwater propulsion components 1100 allows the buoy to move easily under command, thus meeting the needs of different usage scenarios.

[0063] Furthermore, the underwater propulsion component 1100 includes a housing, a propeller, and a motor, which are connected to a battery via cables, and will not be described in detail here.

[0064] To better understand this invention, the following is combined with... Figures 1 to 6 The technical solution of the present invention will be described in detail below: The buoy is equipped with at least one battery and at least one photovoltaic panel movably connected to the buoy, having a first state of being unfolded relative to the float 100 and a second state of being folded relative to the float 100. The photovoltaic panel 310 is electrically connected to the battery for generating electricity using solar energy. A wind power generation component 400 and at least one wave power generation component 500 are respectively connected to the float 100 and electrically connected to the battery for generating electricity using wind and wave energy. Compared to existing technologies, by equipping the buoy with at least one photovoltaic panel 310, a wind power generation component 400, and at least one wave power generation component 500 respectively electrically connected to the battery, the buoy can simultaneously utilize wind, solar, and wave energy resources from seawater and convert them into electrical energy for storage. Furthermore, the photovoltaic panel 310's unfolded state relative to the float 100 and folded state relative to the float 100 enhances the photovoltaic panel's resistance to wind and waves, thereby improving the stability and continuity of power generation, resulting in high utilization and efficiency of ocean energy.

[0065] Furthermore, the rational spatial configuration of at least one photovoltaic element 310, wind power generation component 400, and at least one wave power generation component 500 in this device effectively addresses the different resource requirements of different power generation devices, significantly enhances the power generation capacity of the equipment, improves the utilization rate of marine resources and power generation efficiency, and provides solid technical support for ensuring ocean operations.

[0066] Furthermore, the photovoltaic element 310 in this device can maximize the capture of light energy while saving space, achieving "high output in a small space"; the intelligent light-sensing system can accurately identify scenes with insufficient light intensity, automatically retract the photovoltaic panel, effectively reduce the corrosion and damage of the panel caused by environmental factors, and further ensure the stable operation and service life of the device.

[0067] Furthermore, the support 320 used to connect the wind power generation module 400 and multiple photovoltaic panels can rotate relative to the floating body 100 around the X-axis or Y-axis in the Cartesian coordinate system, respectively, to ensure that the wind and wave power generation devices can generate electricity efficiently and work together under their respective suitable operating conditions. On the other hand, it effectively offsets the impact of wave swaying, significantly reduces metal wear caused by continuous shaking of the top central shaft, and extends the service life of key components of the device.

[0068] Furthermore, compared to traditional power generation methods, the effective utilization rate of wind power generation devices in this invention is significantly improved by 26.4% to 36.4%, and the effective utilization rate of photovoltaic power generation devices is simultaneously improved by 5% to 10%. Moreover, the daily maintenance costs of both types of power generation devices are reasonably reduced by 20% to 30%, and both operation and maintenance efficiency and economy are optimized. For wave power generation devices, by adopting a honeycomb layout design, its effective utilization rate is improved by about 18.2% compared to traditional power generation methods. The scientific layout structure further enhances energy capture efficiency and space utilization efficiency.

[0069] This application, through the aforementioned structure, can solve the technical problem in the prior art that self-generating buoys can only utilize one or two of wind energy, solar energy, and wave energy resources, resulting in low utilization rate and low power generation efficiency of ocean energy.

[0070] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention.
