They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0080] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0081] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides an electromagnetic hybrid wave energy harvesting device based on the prior art, comprising: a float assembly 40, which includes a rotating rod 401, a supporting rod 402, a bearing support 403, a float holder 404, and a float 405. The rotating rod 401 is movably connected to the supporting rod 402 via the bearing support 403. The float holder 404 is connected to one end of the rotating rod 401, and the float 405 is connected to the float holder 404. The float 405 is used to cooperate with the water surface so that the rotating rod 401 drives the supporting rod 402 to rotate in a preset direction; a transmission assembly 20, the input end of which is connected to one end of the supporting rod 402; and an electromagnetic power generation assembly 10. Electromagnetic power generation component 10 is disposed on the first side of transmission component 20. The input end of electromagnetic power generation component 10 is connected to the first output end of transmission component 20. The first output end of transmission component 20 is controlled to drive the input end of electromagnetic power generation component 10 to rotate, so that electromagnetic power generation component 10 generates electrical energy. Triboelectric power generation component 30 is disposed at a distance from electromagnetic power generation component 10. Triboelectric power generation component 30 is disposed on the second side of transmission component 20. The input end of triboelectric power generation component 30 is connected to the second output end of transmission component 20. The second output end of transmission component 20 is controlled to drive the input end of triboelectric power generation component 30 to rotate, so that triboelectric power generation component 30 generates electrical energy. Float component 40 is disposed at a distance from electromagnetic power generation component 10 and triboelectric power generation component 30 respectively.

[0082] In this embodiment, the float 405 in the float assembly 40 cooperates with the water surface and is movably connected to the support rod 402 via the rotating rod 401 and bearing support 403. It can flexibly capture the mechanical energy of waves of different intensities and frequencies and convert it into rotational motion. The transmission assembly 20 transmits the rotation transmitted by the support rod 402 to the electromagnetic power generation assembly 10 on the first side and the triboelectric power generation assembly 30 on the second side, realizing the coordinated work of the two power generation methods and greatly improving the overall conversion efficiency of wave energy. At the same time, the electromagnetic power generation assembly 10 and the triboelectric power generation assembly 30 are spaced apart, and the float assembly 40 is spaced apart from both, reducing the motion interference between the components. Combined with the stable support of the bearing support 403 for the rotating rod 401 and the support rod 402, the stability and durability of the device operation are effectively guaranteed.

[0083] Furthermore, such as Figure 3As shown, the transmission assembly 20 includes: a transmission support frame 202, which is spaced apart from the float assembly 40; a transmission drive wheel 203, which is connected to one end of the support fixing rod 402; a transmission driven wheel 201, which is movably connected to the transmission support frame 202, and is spaced apart from the transmission drive wheel 203 and the transmission support frame 202; and a transmission belt 204, which movably connects the transmission drive wheel 203 and the transmission driven wheel 201.

[0084] In this embodiment, the transmission support frame 202 and the float assembly 40 are spaced apart, which can prevent the movement of the float assembly 40 from interfering with the transmission structure and provide stable support for the transmission process. The transmission drive wheel 203 is connected to one end of the support fixing rod 402, which can efficiently receive the rotational power transmitted by the float assembly 40. The transmission driven wheel 201 is movably connected to the transmission support frame 202 and is spaced apart from the transmission drive wheel 203 and the transmission support frame 202, which reduces contact friction and ensures the flexibility of rotation. The transmission belt 204 movably connects the transmission drive wheel 203 and the transmission driven wheel 201, realizing the smooth transmission of power. Moreover, the belt drive has buffering and shock absorption characteristics, which can adapt to small fluctuations in power transmission, thus improving the overall transmission efficiency and operational stability.

[0085] like Figures 4-8 As shown, the electromagnetic power generation assembly 10 includes: an electromagnetic power generation housing assembly having a first mounting cavity; a first drive rod 103 being movably connected to the electromagnetic power generation housing assembly, a portion of the first drive rod 103 being disposed within the first mounting cavity, and a first end of the first drive rod 103 being connected to the first output end of the transmission assembly 20.

[0086] Rotating bracket 115, movably connected to the electromagnetic power generation housing assembly, with its first end connected to the second end of the first drive rod 103; gear ring 113, connected to the rotating bracket 115; planetary gear 112, including at least one planetary gear 112, which meshes with the gear ring 113 and is movably connected to the electromagnetic power generation housing assembly; central gear 114, meshing with the planetary gear 112, and spaced apart from the gear ring 113; second drive rod 108, second... The first end of the drive rod 108 is connected to the center wheel 114, and the second drive rod 108 is spaced apart from the first drive rod 103; a conductive slip ring 110 is connected to the second drive rod 108; a wire support 111 is connected at its first end to the conductive slip ring 110, and at its second end to the outside of the electromagnetic power generation housing assembly; a coil disk 109 is rotatably mounted on the second drive rod 108 and is connected to the rotating bracket 115; and multiple coils 107 are included in the coil disk 109. Coils 107 are spaced apart around the circumference of coil disk 109; magnet disk 105 is connected to the second end of the second drive rod 108, and is spaced apart from coil disk 109, and is movably connected to rotating bracket 115; magnets 106, including multiple magnets 106, are spaced apart around the circumference of magnet disk 105, and are adjacent to multiple coils 107; wherein, rotating bracket 115, gear ring 113, planetary gear 112, central gear 114, second drive rod 108, and conductive slip ring 110 are included. Coil disk 109, magnet disk 105, and magnet 106 are respectively disposed in the first mounting cavity. The first output end of the operation transmission assembly 20 rotates along a preset direction, so that the first drive rod 103 drives the rotating bracket 115 to rotate. The rotating bracket 115 drives the coil disk 109 and the gear ring 113 to rotate respectively. The gear ring 113 drives the planetary gear 112 to rotate. The planetary gear 112 drives the center gear 114 to rotate. The center gear 114 drives the magnet disk 105 to rotate through the second drive rod 108. The magnet disk 105 rotates in the opposite direction to the coil disk 109.

[0087] In this embodiment, the first mounting cavity of the electromagnetic power generation housing assembly can protect internal components such as the rotating bracket 115, gear ring 113, planetary gears 112, and central gear 114, reducing interference from the external environment. The first drive rod 103 stably transmits the power of the transmission assembly 20 to the rotating bracket 115, causing the coil disk 109 and gear ring 113 to rotate synchronously. The engagement of the gear ring 113, planetary gears 112, and central gear 114, through the second drive rod 108, drives the magnet disk 105 to rotate in the opposite direction, causing the magnet disk 105 and the coil disk 109 to rotate in the opposite direction. The reverse adjacent motion of the 9th coil significantly increases the magnetic line cutting speed between the multiple magnets 106 and the multiple coils 107, thus significantly enhancing the electromagnetic induction effect. The multiple coils 107 are spaced apart around the circumference of the coil disk 109, and the multiple magnets 106 are spaced apart around the circumference of the magnet disk 105 and distributed adjacently, increasing the induction area and further improving the power generation efficiency. The conductive slip ring 110 cooperates with the wire support 111 to effectively solve the problem of wire entanglement when the second drive rod 108 rotates, ensuring stable power output. The overall structure is compact and the operation is reliable.

[0088] In one exemplary embodiment, multiple magnets 106 are arranged in an alternating N-S configuration to increase the rate of change of magnetic flux and improve the output voltage.

[0089] Specifically, the electromagnetic power generation housing assembly includes: a first electromagnetic power generation housing 101, which is movably connected to a rotating bracket 115, a gear ring 113, a planetary gear 112, and a central gear 114; and a second electromagnetic power generation housing 102, which is movably connected to the rotating bracket 115 and a first drive rod 103, and the second electromagnetic power generation housing 102 and the first electromagnetic power generation housing 101 form a first mounting cavity. The first electromagnetic power generation housing 101 is movably connected to the rotating bracket 115, the gear ring 113, the planetary gear 112, and the central gear 114, providing stable support and flexible rotation space for these transmission and power generation components, ensuring smooth transmission and coordination. The second electromagnetic power generation housing 102 is movably connected to the rotating bracket 115 and the first drive rod 103, guiding and limiting the power transmission of the first drive rod 103 and the movement of the rotating bracket 115, enhancing the stability of power transmission. Furthermore, the first electromagnetic power generation housing 101 and the second electromagnetic power generation housing 102 form a first mounting cavity, which can encapsulate internal parts such as the rotating bracket 115 and the gear ring 113, effectively isolating them from external environmental interference and protecting the internal structure. At the same time, the split structure facilitates the assembly and maintenance of parts, improving the reliability and practicality of the components.

[0090] In an exemplary embodiment, the electromagnetic power generation assembly 10 further includes an electromagnetic power generation bracket 104, which is connected to the outside of the electromagnetic power generation housing assembly. The electromagnetic power generation bracket 104 provides stable external support for the entire electromagnetic power generation assembly 10, reliably fixing the electromagnetic power generation housing assembly and internal components such as the first drive rod 103, rotating bracket 115, and gear ring 113 in a preset position of the device. This prevents misalignment between the electromagnetic power generation assembly 10 and the transmission assembly 20 due to overall swaying caused by waves, ensuring stable engagement between the first drive rod 103 and the first output end of the transmission assembly 20. Simultaneously, it enhances the overall structural strength of the electromagnetic power generation assembly 10, reduces the impact of external impacts on internal components, and facilitates the assembly and positioning of the electromagnetic power generation assembly 10 with other parts of the device, improving the ease of assembly and operational reliability.

Gear 306, support plate 309, third friction gear 307, fourth drive shaft, fourth friction gear 308, friction rotor 312, FEP friction material sheet 311, stator ring 302 and copper foil electrode sheet 310 are arranged in the second mounting cavity. The second output end of the operation transmission assembly 20 rotates along a preset direction. The third drive shaft 304 drives the first friction gear 313 to rotate. The first friction gear 313 drives the fourth drive shaft to rotate through the second friction gear 306, the third friction gear 307 and the fourth friction gear 308. The fourth drive shaft drives the adjacent copper foil electrode sheet 310 of the FEP friction material sheet 311 on the friction rotor 312 to rotate.

[0092] In this embodiment, the second mounting cavity of the triboelectric generator housing assembly can encapsulate internal components such as the first friction gear 313, the second friction gear 306, and the friction rotor 312, effectively isolating them from external interference such as seawater and impurities, and protecting the core triboelectric generator structure. The third drive shaft 304 can stably receive the power from the transmission assembly 20 and transmit it to the first friction gear 313. Then, through the cooperation of the first friction gear 313 and the second friction gear 306, the transmission of the third friction gear 307 and the fourth friction gear 308, and the stable support of the support plate 309 for the third friction gear 307 and the fourth drive shaft, efficient and smooth power generation is ensured. The energy is smoothly transmitted to the fourth drive shaft, driving the friction rotor 312 to rotate stably. Multiple FEP friction material sheets 311 spaced circumferentially on the friction rotor 312 rotate adjacent to multiple copper foil electrode sheets 310 spaced circumferentially on the inner ring of the stator ring 302, which greatly increases the friction contact area and charge generation efficiency. The FEP friction material sheets 311 and the friction rotor 312 are spaced apart from each friction gear to avoid motion interference. At the same time, the connection between the stator ring 302 and the triboelectric housing assembly further improves the overall structural stability, ensures the continuous and reliable triboelectric power generation process, and effectively improves the conversion efficiency of wave energy to electrical energy.

[0093] In one exemplary embodiment, the gap between the FEP friction material sheets 311 is 0.8~1.2mm to achieve high sensitivity output and extend lifespan.

[0094] In one exemplary embodiment, the support plate 309 is provided with heat dissipation holes to reduce the temperature rise during the friction process and ensure stable signal output.

[0095] Furthermore, the triboelectric housing assembly includes: a second triboelectric housing 303, which is movably connected to a third drive shaft 304 and a second friction gear 306, and is connected to a support plate 309; and a first triboelectric housing 301, which is connected to the support plate 309 and a stator ring 302, and the first triboelectric housing 301 and the second triboelectric housing 303 form a second mounting cavity.

[0096] In this embodiment, the second triboelectric housing 303 is movably connected to the third drive shaft 304 and the second friction gear 306, providing stable support and flexible rotation space for the third drive shaft 304 to transmit power to the transmission assembly 20 and for the second friction gear 306 and the first friction gear 313 to engage and transmit power, preventing component misalignment during power transmission and ensuring smooth transmission. Its connection to the support plate 309 further stabilizes the installation positions of components such as the third friction gear 307 and the fourth drive shaft, enhancing the overall stability of the transmission structure. The first triboelectric housing 301 is connected to the support plate 309 and the stator ring 302, strengthening the fixation of the support plate 309 and increasing support strength together with the second triboelectric housing 303. It also reliably fixes the stator ring 302, ensuring that the multiple copper foil electrode plates 310 on the inner ring of the stator ring 302 are always precisely adjacent to the FEP friction material plates 311 on the friction rotor 312, preventing displacement of the stator ring 302 from affecting the triboelectric generation effect. In addition, the second triboelectric housing 303 and the first triboelectric housing 301 form a second mounting cavity, which can encapsulate the internal core components such as the first friction gear 313 and the friction rotor 312, effectively isolating external interference such as seawater and impurities, protecting the internal triboelectric structure, and the split design facilitates the assembly and subsequent maintenance of internal components, thus improving the overall operational reliability and practicality of the triboelectric assembly 30.

[0097] In one exemplary embodiment, the triboelectric power generation assembly 30 further includes a triboelectric power generation bracket 305, which is connected to the outside of the triboelectric power generation housing assembly. The triboelectric power generation bracket 305 provides stable external support for the entire triboelectric power generation assembly 30, reliably fixing the triboelectric power generation housing assembly and its internal core components such as the third drive shaft 304, the first friction gear 313, the friction rotor 312, the FEP friction material sheet 311, and the copper foil electrode sheet 310. This prevents the triboelectric power generation housing assembly from shifting due to wave-induced shaking, thus avoiding misalignment between the third drive shaft 304 and the second output end of the transmission assembly 20, ensuring the stability of power transmission. Simultaneously, the bracket enhances the overall structural strength of the triboelectric power generation assembly 30, reducing the impact of external impacts on the internal friction transmission components and triboelectric power generation components, preventing damage to their adjacent rotational fit due to structural loosening. Furthermore, the triboelectric power generation bracket 305 facilitates the assembly and positioning of the triboelectric power generation assembly 30 with other parts of the device, improving the ease of assembly installation and further ensuring the continuous reliability of the triboelectric power generation process.

[0098] like Figure 13As shown, the first embodiment of the present invention provides an electromagnetic hybrid wave energy harvesting system based on the prior art, including an electromagnetic hybrid wave energy harvesting device, which is the aforementioned electromagnetic hybrid wave energy harvesting device. The electromagnetic hybrid wave energy harvesting system further includes: a first rectifier module electrically connected to the stator coil 302, used to collect a first current generated by the copper foil electrode sheet 310 on the stator coil 302; a second rectifier module electrically connected to the conductive slip ring 110, used to collect a second current generated by the coil 107 on the coil disk 109; an energy storage module electrically connected to both the first and second rectifier modules, used to acquire and store the first and second currents; a boost module electrically connected to the energy storage module, used to acquire the voltage output by the energy storage module and boost it to obtain a preset voltage; and an energy management module electrically connected to the boost module, used to acquire the preset voltage and supply it to external devices.

[0099] In this embodiment, the first rectifier module is electrically connected to the stator coil 302, which can accurately collect and rectify the first current generated by the copper foil electrode sheet 310 of the inner ring of the stator coil 302. At the same time, the second rectifier module is electrically connected to the conductive slip ring 110, which can effectively collect and rectify the second current generated by the coil 107 on the coil disk 109 transmitted by the conductive slip ring 110, ensuring that the current generated by the two power generation components can be converted into stable DC power. The energy storage module is electrically connected to the first and second rectifier modules respectively, which can efficiently store the current after rectification of the two paths, avoiding energy waste caused by wave energy fluctuations. The boost module works with the energy storage module to boost the voltage output of the energy storage module to a preset value to meet the voltage requirements of different external devices. The energy management module is electrically connected to the boost module, which can intelligently allocate the preset voltage after boosting and supply it to external devices to realize on-demand energy utilization. Moreover, the entire system relies on the aforementioned efficient electromagnetic hybrid wave energy collection device, which not only ensures the high efficiency of wave energy conversion, but also realizes the stability and practicality of energy utilization.

[0100] like Figure 14 As shown, the first embodiment of the present invention provides an electromagnetic hybrid wave energy harvesting method based on the prior art, the specific content of which is as follows:

[0101] In the electromagnetic hybrid wave energy harvesting device, the float assembly 40 moves with the waves, driving the rotating rod 401 and the supporting fixed rod 402 to rotate. The power is transmitted to the electromagnetic power generation assembly 10 and the triboelectric power generation assembly 30 through the transmission assembly 20. In the electromagnetic power generation assembly 10, the transmission assembly 20 drives the first drive rod 103 to rotate, which causes the magnet disk 105 and the coil disk 109 to rotate in opposite directions through the planetary gear system. The coil 107 and the magnet 106 generate electromagnetic induction to generate electrical energy. In the triboelectric power generation assembly 30, the transmission assembly 20 drives the third drive shaft 304 to rotate. Through multi-stage friction gear transmission, the FEP friction material sheet 311 on the friction rotor 312 rotates adjacent to the copper foil electrode sheet 310 of the stator ring 302, generating electrical energy through friction electrification.

[0102] Next, the first rectifier module of the electromagnetic hybrid wave energy harvesting system collects the first current generated by the copper foil electrode 310 of the triboelectric generator 30, and the second rectifier module collects the second current transmitted by the conductive slip ring 110 of the electromagnetic generator 10. Both currents are rectified and then input into the energy storage module for storage. The voltage output from the energy storage module is boosted to a preset value by the boost module and supplied to external devices by the energy management module. Simultaneously, the electrical signals generated during the power generation process are collected by the electrical signal acquisition device, transmitted to the host computer for processing, and then input into the machine learning training module to predict the wave amplitude and frequency.

[0103] For the predicted amplitude, if the predicted value is less than the first-level threshold, a green warning light will illuminate; if it is not less than the first-level threshold but less than the second-level threshold, a yellow warning light will illuminate; if it is not less than the second-level threshold, a red warning light will illuminate.

[0104] For predicted frequencies, if the predicted value is less than the first-level threshold, a green warning light will illuminate; if it is not less than the first-level threshold but less than the second-level threshold, a yellow warning light will illuminate; if it is not less than the second-level threshold, a red warning light will illuminate.

[0105] The entire process achieves hybrid collection of wave energy, rectification, storage, and intelligent distribution of electrical energy. At the same time, through machine learning prediction of electrical signals, it provides graded warnings for wave conditions, ensuring the safety and efficiency of device operation and energy utilization.

[0106] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Other modifications can be readily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown and described herein.
