Description

Technical Field

[0001] This invention relates to a magnetically levitated contact 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. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a magnetically levitated contact wave energy harvesting structure that is inexpensive, simple in structure, stable and reliable, has a long working life and can be easily installed.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A magnetically levitated contact wave energy harvesting structure includes: a top cover (1) and a bottom cover (9) fixedly installed at the upper and lower ends of a cylinder (2); a shaft (15) fixedly installed in the center hole of the top cover (1) and the bottom cover (9); round holes for seawater and air to freely enter and exit are provided around the top cover (1) and the bottom cover (9); a linear bearing one (14) and a linear bearing two (10) are installed on the shaft (15); the linear bearing one (14) is fixedly connected to the magnet one (11); the magnet one (11) and the sealing cover (3) form a sealed cavity; the electrode one (4) and the electrode two (6) are fixedly bonded to the top and bottom of the sealed cavity; the friction layer (5) is installed between the spring one (12) and the spring two (13); the linear bearing two (10) is fixedly connected to the buoyancy block (8); the upper end of the buoyancy block (8) is fixedly connected to the magnet two (7).

[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.

[0027] Figure 1The diagram shows a cross-section of a wave energy harvesting structure. This embodiment of a magnetically levitated contact 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 15 fixedly installed in the center hole of the top cover 1 and bottom cover 9; circular holes around the top cover 1 and bottom cover 9 for free entry and exit of seawater and air; linear bearing 14 and linear bearing 20 mounted on the shaft 15; linear bearing 14 fixedly connected to magnet 11; magnet 11 and sealing cover 3 forming a sealed cavity; electrode 14 and electrode 26 fixedly bonded to the top and bottom of the sealed cavity; friction layer 5 installed between spring 12 and spring 23; linear bearing 20 fixedly connected to buoyancy block 8; and the upper end of buoyancy block 8 fixedly connected to magnet 27.

[0028] 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 15, the top cover 1 has holes around its perimeter to allow seawater and air to freely enter and exit.

[0029] 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 11 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.

[0030] The friction layer 5 is sandwiched between spring 12 and spring 23. When the internal structure undulates, the friction layer 5 will periodically contact and separate from the electrodes 14 and 26 under the combined action of spring 12 and spring 23, and generate electricity through the coupling effect of triboelectric charging and electrostatic induction.
