Description

Technical Field

[0001] The present invention relates to the technical field of wave energy power generation, and in particular to a floating composite wave energy capture device based on electromagnetic-triboelectricity. Background Art

[0002] Widespread deployment of offshore sensors is fundamental to ocean monitoring and plays a crucial role in developing a smart ocean. However, a key bottleneck hindering the development of these sensors is the availability of electrical power. The constantly rising and falling waves of the ocean contain abundant energy, and wave energy has attracted considerable attention as a potential clean, renewable energy source. Given its widespread distribution and vast reserves, fully utilizing this energy for efficient and reliable wave power generation is crucial.

[0003] Existing technologies typically convert wave energy into mechanical energy. By buoying a floating body on the water surface, mechanical transmission drives the relative motion of magnets and induction coils in a power generation device, converting the wave energy into electrical energy for output. However, these devices suffer from limited functionality, low energy capture efficiency, high installation costs, and difficulty in widespread application.

[0004] Therefore, there is an urgent need for a wave energy power generation device with a composite energy capture method to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the existing technology and thus provide a composite energy capture method based on electromagnetic-triboelectricity to fully utilize the wave energy in the marine environment and improve the power generation efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a floating composite wave energy capture device based on electromagnetic-triboelectricity, characterized in that it includes a support column, an elastic band fixed end, a rotating hook, a base, a float, an elastic band, a hook, a float fixing clamp, an electromagnetic energy capture module, an electromagnetic energy capture module fixed end, and a triboelectric energy capture structure; one end of the float is connected to the hook and connected to the support column through the float fixing clamp, and then the support column is connected to the base fixing clamp through the rotating hook and fixed to the base; the other end is connected to the elastic band hook and the elastic band through the fixing clamp, and is fixed to the base through the elastic band fixed end, and its function is to convert wave energy into kinetic energy; the coil is installed on the electromagnetic energy capture module housing, the magnet is installed on the fixed shaft, one side of the electromagnetic energy capture module housing is in contact with the elastic band, and the fixed shaft is fixed to the base through the electromagnetic energy capture module fixed ends on both sides, and the above structures together constitute the electromagnetic energy capture structure; the perfluoroethylene propylene copolymer is adhered to the outer wall of the triboelectric device, the triboelectric device is fixed on the elastic band, and the copper sheet is fixed on the base, and the above structures together constitute the triboelectric energy capture structure.

[0007] Furthermore, the floating body will move in all directions during the wave motion, and the reciprocating stretching and contraction of the elastic band drives the coil installed on the shell to rotate relative to the magnet, thereby converting wave energy into rotational kinetic energy.

[0008] Furthermore, the floating body will move in all directions during the wave motion, driving the magnet to cut the magnetic flux lines of the coil, thereby outputting voltage according to Faraday's law of electromagnetic induction.

[0009] Furthermore, the floating body will move in all directions during the wave motion, and the reciprocating stretching and contraction of the elastic band will drive the triboelectric device to move back and forth.

[0010] Furthermore, the floating body will vibrate in all directions during the wave motion, driving the perfluoroethylene propylene copolymer attached to the triboelectric device to continuously rub against the copper sheet, thereby outputting voltage.

[0011] The effects achieved by the present invention are:

[0012] 1. The floating electromagnetic-triboelectric composite wave energy capture device utilizes the elastic band's ability to be stretched in any direction, combined with the motion of the float, to capture omnidirectional wave energy. This allows the device to adapt to the complex and changing wave environments found in nature and offers the advantage of ease of engineering promotion and application.

[0013] 2. The floating electromagnetic-triboelectric composite wave energy capture device utilizes electromagnetic and triboelectric composite energy capture, integrating the energy capture advantages of electromagnetic and triboelectric, and greatly improving the energy capture efficiency.

[0022] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 7 As shown, the electromagnetic-triboelectric floating composite wave energy capture device described in this embodiment includes a support column 2, a fixing clamp 10, a rotating hook 11, a base 8, a float 1, an elastic band 3, a hook 7, an electromagnetic energy capture module 4, an electromagnetic energy capture module fixing end 14, a triboelectric energy capture structure 6, a base fixing clamp 5, an elastic band fixing end 12, and an elastic band hook 9. One end of the float 1 is connected to the hook 7 and to the support column 2 via the float fixing clamp 13, and is fixed to the base 8 via the rotating hook 11 and the base fixing clamp 5. The other end of the float 1 is connected to the elastic band hook 9 and the elastic band 3 through a fixing clip 10, and is fixed to the base 8 through the elastic band fixed end 12; the coil 16 is installed on the electromagnetic energy capture module housing 18, and the magnet 15 is installed on the fixed shaft 17. One side of the electromagnetic energy capture module housing 18 is in contact with the elastic band 3, and the fixed shaft 17 is fixed to the base 8 through the electromagnetic energy capture module fixed ends 14 on both sides. The above structures together constitute an electromagnetic energy capture structure; the perfluoroethylene propylene copolymer 19 is adhered to the triboelectric device 20, the triboelectric device 20 is fixed on the elastic band 3, and the copper sheet 21 is fixed on the base 8. The above structures together constitute a triboelectric energy capture structure 6.

[0024] More specifically: the float 1 will move in all directions during the wave movement, so that the reciprocating stretching and contraction of the elastic belt 3 drives the coil 16 installed on the electromagnetic energy capture module housing 18 to rotate, thereby converting the wave energy into rotational kinetic energy, driving the magnet 15 to cut the magnetic flux lines of the coil 16, thereby outputting voltage; the reciprocating stretching and contraction of the elastic belt 3 drives the triboelectric device 20 to reciprocate, driving the perfluoroethylene propylene copolymer 19 attached to the triboelectric device 20 to continuously rub against the copper sheet 21, thereby generating voltage.

[0025] Working Principle: When the floating body 1 is subjected to wave action, it undergoes omnidirectional reciprocating motion, causing the elastic band 3 to undergo reciprocating deformation. This deformation, on the one hand, drives the coil 16 to rotate relative to the magnet 15, thereby generating voltage and achieving electromagnetic energy capture. On the other hand, the reciprocating deformation of the elastic band 3 also drives the triboelectric device 20 to reciprocate relative to the copper sheet 21, causing the perfluoroethylene propylene copolymer 19 attached to the triboelectric device 20 to continuously rub against the copper sheet 21, thereby generating voltage and achieving triboelectric energy capture. This device combines the advantages of electromagnetic and triboelectric composite energy capture, capable of omnidirectionally capturing ocean wave energy. It is widely used in ocean sensors or for wave energy capture in complex and changing sea areas.

Any person skilled in the art may make modifications and variations in the implementation and details without departing from the core technical solutions disclosed herein. However, the scope of protection defined by the present invention shall remain subject to the scope defined in the appended claims.
