Technical Field

[0001] This invention relates to a magnetically levitated finger electrode wave energy harvesting structure, belonging to the field of wave energy harvesting technology. Background Technology

[0002] Despite decades of development, traditional electromagnetic ocean energy generation equipment still faces limitations in wave energy harvesting. The irregular motion and low frequency of waves severely hinder the widespread adoption of such equipment. Furthermore, the generally high equipment and installation / maintenance costs directly restrict the application of wave energy generation equipment based on electromagnetic principles.

[0003] Nano-triboelectric generators have attracted widespread attention across various industries due to their numerous application advantages. A novel energy harvesting technology based on triboelectricity and electrostatic induction, nano-triboelectric generators are characterized by their ability to effectively utilize low-frequency mechanical energy for power generation. This provides a new approach to ocean energy harvesting and is an indispensable part of the future recyclable energy field.

[0004] Nano-triboelectric generators are characterized by their simple structure and low cost, which makes them highly scalable. They also have low overall structural mass and are easy to install and maintain. They have already been applied in some self-powered fields and will provide more solutions in the future in fields such as marine engineering, machinery manufacturing, rail transportation, and aerospace.

The electrode cylinder (4) of the interdigitated electrode structure is fixedly installed inside the sealing cover (3), and the friction layer (5) is installed between spring one (12) and spring two (11). The characteristic is that the friction layer (5), spring one (12) and spring two (11) all have gaps with the inside of the sealing cover (3); the magnet one (6) and magnet two (7) are magnetically repulsive to achieve magnetic levitation; the material of the interdigitated electrode inside the electrode cylinder (4) is aluminum; and the material of the friction layer (5) is polytetrafluoroethylene (PTFE).

[0008] The advantages of this invention are: the overall structure can be fixedly installed on marine targets such as buoys; the cylindrical structure not only transforms the irregular motion of ocean waves into a single degree of freedom motion along the axial direction, but also has a good self-protection capability, increasing the working life of the structure.

[0024] Figure 1 The diagram shows a cross-section of a wave energy harvesting structure. This embodiment of a magnetically levitated finger electrode wave energy harvesting structure specifically includes: a top cover 1 and a bottom cover 9 fixedly installed at the upper and lower ends of a cylinder 2; a shaft 14 fixedly installed in the center hole of the top cover 1 and bottom cover 9; a linear bearing 13 and a linear bearing 10 mounted on the shaft 14; the linear bearing 10 fixedly connected to a buoyancy block 8, which is fixedly connected to a magnet 7; the linear bearing 13 fixedly connected to a magnet 6; the magnet 6 and the sealing cover 3 form a sealed cavity; an electrode cylinder 4 with a finger electrode structure on its inner side is fixedly installed inside the sealing cover 3; a friction layer 5 is installed between a spring 12 and a spring 11; the friction layer 5, spring 12, and spring 11 all have gaps with the inner side of the sealing cover 3; the magnet 6 and magnet 7 are magnetically repelled to achieve magnetic levitation; the material of the finger electrode inside the electrode cylinder 4 is aluminum; and the material of the friction layer 5 is polytetrafluoroethylene (PTFE).

[0025] Figure 2 The diagram shows a front view of the top cover 1, which is identical to the bottom cover 9. Except for the central hole for mounting the shaft 14, the top cover 1 has holes around its perimeter to allow seawater and air to freely enter and exit.

[0026] Figure 3 The diagram shows the unfolded structure of the inner ring of the electrode cylinder 4 with inserted finger electrodes.

[0027] When the wave energy harvesting structure is in operation, it will be fixed on a floating platform or other water surface platform, with part of the structure immersed in seawater. The buoyancy block 8 can keep the internal structure on the water surface under the action of seawater. The rise and fall of the waves will cause the entire internal structure to rise and fall along the axis. Magnet 1 6 and Magnet 2 7 are installed with magnetic repulsion. This structure can lift the power generation structure away from the water surface and can also achieve a buffering function.

[0028] The friction layer 5 is installed between spring 12 and spring 21. When the internal structure moves up and down, the friction layer 5 will move up and down periodically under the combined action of spring 12 and spring 21. During the movement, the friction layer 5 will contact and separate from the two electrodes of the finger electrode inside the electrode cylinder 4, and generate electricity through the coupling effect of friction electrification and electrostatic induction.
