Technical Field

[0001] This invention relates to a magnetically levitated vertical contact separation 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.

A (10) and a sealing cover (3) form a sealed cavity. The third friction layer (501) and the fourth friction layer (502) are fixedly bonded to the bottom of the sealed cavity. The mass ring (401), the upper plate (402), the first friction layer (403) and the second friction layer (404) are fixedly bonded to the upper end of the spring (11). The lower end of the spring (11) is fixedly installed at the bottom of the sealed cavity. The second linear bearing (9) is fixedly connected to the buoyancy block (7).

[0029] Figure 1 The cross-section of the wave energy harvesting structure is shown. This embodiment of a magnetically levitated vertical contact separation wave energy harvesting structure specifically includes: a top cover 1 and a bottom cover 8 fixedly installed at the upper and lower ends of a cylinder 2; a shaft 13 fixedly installed in the center hole of the top cover 1 and bottom cover 8; circular holes for seawater and air to freely enter and exit the top cover 1 and bottom cover 8; a linear bearing 12 and a linear bearing 9 installed on the shaft 13; the linear bearing 12 is fixedly connected to a magnet 10, which forms a sealed cavity with the sealing cover 3; a third friction layer 501 and a fourth friction layer 502 are fixedly bonded to the bottom of the sealed cavity; a mass ring 401, an upper plate 402, a first friction layer 403, and a second friction layer 404 are fixedly bonded to the upper end of a spring 11, and the lower end of the spring 11 is fixedly installed at the bottom of the sealed cavity; the linear bearing 9 is fixedly connected to a buoyancy block 7, and the upper end of the buoyancy block 7 is fixedly connected to a magnet 6.

[0030] Figure 2 The diagram shows a front view of the top cover 1, which is identical to the bottom cover 8. Except for the central hole for mounting the shaft 13, the top cover 1 has holes around its perimeter to allow seawater and air to freely enter and exit.

[0031] 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 7 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 10 and Magnet 26 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.

[0032] The structure in which the mass ring 401, the upper plate 402, the first friction layer 403 and the second friction layer 404 are fixedly bonded together achieves periodic contact separation with the third friction layer 501 under the combined action of inertia and spring 11, and generates electricity through the coupling effect of triboelectric charging and electrostatic induction.
