[0028] This invention proposes a self-generating fish-attracting device 100.

[0029] Please see Figure 1 and Figure 2In one embodiment of the present invention, the self-generating fish attracting device 100 is applied to a flowing water area. It includes a shaft 1, a moving magnetic ring 3, and a light emitter. The shaft 1 is provided with a coil winding 2. The moving magnetic ring 3 is rotatably sleeved on the shaft 1. The outer peripheral wall of the moving magnetic ring 3 is provided with at least one inclined groove 31. The light emitter is electrically connected to the coil winding 2.

[0030] In the technical solution of this invention, the inclined groove 31 on the moving magnetic ring 3 rotates under the driving force of the water flow, so that the moving magnetic ring 3 rotates and cuts the magnetic field lines of the coil winding 2, thereby generating an induced current in the coil winding 2, which in turn powers the light emitter; the shaft 1 is the main structural component of the device, and the coil winding 2 is provided inside the shaft 1 to sense the electromotive force generated when the moving magnetic ring 3 rotates; the moving magnetic ring 3 is designed to be rotatably fitted inside the shaft 1, and its outer peripheral wall is provided with an inclined groove 31, which helps to generate rotational power under the impact of the water flow; the light emitter is electrically connected to the coil winding 2 for... The induced current is converted into light energy to emit light that attracts fish. The solution provided by this invention does not require an external power source and generates its own power using the energy of ocean currents, reducing wiring and maintenance costs and dependence on traditional energy sources, which meets the needs of sustainable development of marine ranches. The number of inclined troughs 31 can be one or multiple at intervals, and this invention does not limit this. In one embodiment, the light emitter can emit light of a specific color spectrum and wavelength, preferably blue or green light, to simulate food sources in the natural environment, attract fish to approach, thereby improving the success rate of catching or observing fish.

[0031] In one embodiment of the present invention, the angle between the extending direction of each of the inclined grooves 31 and the axial direction of the moving magnetic ring 3 is A, wherein 40 degrees ≤ A ≤ 50 degrees. The design of the inclined grooves 31 enables the moving magnetic ring 3 to generate rotational power under the impact of water flow. The water flow pushes the moving magnetic ring 3 through the inclined grooves 31, causing it to rotate and cut the magnetic field lines of the coil winding 2. The angle A between the extending direction of the inclined grooves 31 and the axial direction of the moving magnetic ring 3 helps optimize the conversion efficiency of water flow energy to mechanical rotational energy. An appropriate angle can maximize the driving force of the water flow on the moving magnetic ring 3, thereby improving power generation efficiency. The size of the angle A can also affect the rotational speed of the moving magnetic ring 3; a smaller angle results in a faster rotational speed, while a larger angle results in a slower rotational speed. The rotation speed makes the rotation more stable; the included angle A is between 40 and 50 degrees. The angle selection within this range can balance the rotation speed and force, ensuring that the moving magnetic ring 3 can effectively cut the magnetic field lines while maintaining stable power generation performance; by optimizing the included angle A, the efficiency of water flow energy conversion into mechanical energy can be improved, thereby improving the power generation efficiency of the entire self-generating fish attracting device 100. In addition, the water flow characteristics of different water areas may require different inclined trough 31 designs. By adjusting the angle A, the device can adapt to different water flow conditions and improve its applicability in various environments.

[0032] To improve the power generation efficiency of the device, please refer to Figure 1 In one embodiment of the present invention, each of the inclined grooves 31 extends through the outer peripheral wall of the moving magnetic ring 3 along its extending direction. The inclined grooves 31 extending through the outer peripheral wall of the moving magnetic ring 3 helps to generate greater rotational force under the impact of water flow; when water flows through these through inclined grooves 31, the kinetic energy of the water flow can be more effectively transferred to the moving magnetic ring 3, driving it to rotate, improving the efficiency of converting water flow energy into mechanical energy, thereby improving the power generation efficiency of the entire self-generating fish attracting device 100; the through design of the inclined grooves 31 provides a more uniform water flow distribution and more stable rotational force, which helps to enhance the structural stability of the moving magnetic ring 3.

[0033] To provide consistent rotational power to the moving magnetic ring 3, please refer to... Figure 1In one embodiment of the present invention, the inclined grooves 31 are arranged in parallel. Multiple inclined slots 31 are arranged in parallel on the outer peripheral wall of the moving magnetic ring 3. This arrangement helps to evenly distribute the impact of the water flow on the moving magnetic ring 3, thereby providing consistent rotational power in all directions. The parallel inclined slots 31 can more effectively utilize the kinetic energy of the water flow. The water flow can act on all inclined slots 31 simultaneously, driving the moving magnetic ring 3 to rotate at multiple points, thereby increasing the stability and efficiency of the rotation of the moving magnetic ring 3. When the water flow passes through these parallel inclined slots 31, it can drive the moving magnetic ring 3 to rotate more evenly, thereby generating a more stable induced current in the coil winding 2 and improving the power generation efficiency. The parallel inclined slots 31 help to optimize the structural design of the moving magnetic ring 3, enabling it to rotate more evenly under the impact of the water flow and reducing the structural stress concentration caused by uneven distribution of the water flow. The parallel inclined slot design can also improve the efficiency of converting water flow energy into mechanical rotational energy, thereby improving the overall performance of the self-generating fish attracting device 100. It also enables the moving magnetic ring 3 to adapt to water flow of different directions and intensities, improving the applicability of the device in the variable marine environment.

[0034] To further improve power generation efficiency, please refer to [link / reference]. Figure 1 and Figure 2 In one embodiment of the present invention, the self-generating fish-attracting device 100 includes a plurality of moving magnetic rings 3. A cavity is formed in the shaft 1, and a plurality of parallel-connected coil windings 2 are spaced apart along the axial direction of the shaft 1 within the cavity. The plurality of moving magnetic rings 3 are rotatably fitted onto the shaft 1 at axial intervals, with each moving magnetic ring 3 corresponding to one coil winding 2. The plurality of moving magnetic rings 3 rotate under the action of water flow. The inclined groove 31 of each magnetic ring cuts the magnetic field lines of the corresponding coil winding 2, generating an induced current in each coil winding 2. This current is then transmitted to the light emitter through parallel connection. The light emitter converts the induced current into light energy, emitting light to attract fish. The design of multiple moving magnetic rings 3 allows for the simultaneous capture of water flow energy, improving overall power generation efficiency, enabling the light emitter to emit stronger light, enhancing the fish-attracting effect, and increasing the likelihood of fish aggregation. The design of multiple moving magnetic rings 3 and coil windings 2 provides a more stable structure, contributing to long-term stable operation in marine environments.

[0035] Specifically, please refer to Figure 1 and Figure 2In one embodiment of the present invention, the shaft 1 includes a fixed shaft 11 connected to the two side walls opposite to the cavity. The fixed shaft 11 is axially spaced with multiple mounting discs 12, and each coil winding 2 is mounted on one of the mounting discs 12. The fixed shaft 11, connected to the two side walls opposite to the cavity, provides a stable central axis for the entire device. The mounting discs 12, spaced axially along the fixed shaft 11, support and fix the coil windings 2, ensuring their correct position within the shaft 1. Each coil winding 2 is mounted on a mounting disc 12. This design allows each coil winding 2 to work independently with its corresponding moving magnetic ring 3, thereby generating an induced current in the coil winding 2. The design of the fixed shaft 11 and mounting discs 12 provides a more stable structure, helping to maintain the stable position of the coil windings 2. Multiple coil windings 2 can work simultaneously to generate a stronger induced current, thereby improving the brightness and fish-attracting effect of the emitter.

[0036] For more details, please refer to Figure 1 and Figure 2 In one embodiment of the present invention, each of the moving magnetic rings 3 includes a moving ring 32 and a magnetic block 33. Multiple moving rings 32 are spaced apart axially along the shaft 1 and rotatably fitted onto the shaft 1. Each moving ring 32 contains the magnetic block 33. The moving ring 32 is a key component of the self-generating fish attractant device 100. It is rotatably fitted onto the shaft 1. The outer peripheral wall of the moving ring 32 has inclined grooves 31, which cause the moving magnetic ring 3 to rotate under the push of water flow. The magnetic block 33 is an internal component of the moving magnetic ring 3, responsible for generating the magnetic field. The magnetic block 33 can be made of permanent magnet material to ensure a stable magnetic field output. The fixed position of the magnetic block 33 helps maintain the stability of the magnetic field and reduces magnetic field fluctuations caused by changes in water flow. A stable magnetic field can improve the luminous efficiency of the emitter, thereby improving the fish attractant effect. In one embodiment, the moving ring 32 is made of a corrosion-resistant and wear-resistant material, preferably polytetrafluoroethylene (PTFE).

[0037] Please see Figure 1 and Figure 2In one embodiment of the present invention, each of the moving magnetic rings 32 is provided with a plurality of magnetic blocks 33 spaced circumferentially within it, and each of the mounting disks 12 is provided with a plurality of coil windings 2 spaced circumferentially on its outer peripheral wall. Each magnetic block 33 corresponds to one coil winding 2. The magnetic blocks 33 are evenly distributed inside the moving magnetic rings 3, and each magnetic block 33 can interact with the coil windings 2 when the moving magnetic rings 3 rotate, generating an induced current. The mounting disks 12 are fixed on the shaft 1, and their outer peripheral walls are provided with a plurality of coil windings 2 spaced circumferentially. These coil windings 2 correspond to the magnetic blocks 33 inside the moving magnetic rings 3 and are used to sense the electromotive force generated when the moving magnetic rings 3 rotate. By spaced multiple magnetic blocks 33 and multiple coil windings 2 inside the moving magnetic rings 3, the energy of water flow can be utilized more effectively, and the power generation efficiency can be improved.

[0038] In order to stabilize the induced current generated by the coil winding 2, in one embodiment of the present invention, the self-generating fish attracting device 100 includes a current stabilizer, which is electrically connected to the light emitter and the coil winding 2. The main function of the current stabilizer is to stabilize the induced current generated by the coil winding 2, ensuring current stability, which is crucial for the stable operation of the emitter. The current stabilizer also regulates the voltage to adapt to the operating requirements of the emitter, ensuring it maintains stable brightness under different operating conditions. The current stabilizer provides overload protection to prevent excessive current from damaging the emitter or other circuit components. By optimizing current flow, the current stabilizer helps improve the energy conversion efficiency of the entire self-generating fish attractant device 100. When the moving magnetic ring 3 rotates under the propulsion of the water flow, it cuts the magnetic lines of force of the coil winding 2, generating an induced current in the coil winding 2. This induced current passes through the current stabilizer, which regulates and stabilizes the current before transmitting it to the emitter. The emitter converts the stable current into light energy, emitting light to attract fish. A stable current supply ensures the emitter continuously emits light to attract fish, improving the fish-attracting effect. The current stabilizer's protection function helps improve the reliability of the entire device, reducing malfunctions caused by current fluctuations or overloads. The current stabilizer can adapt to different water flow conditions and fish-attracting needs, ensuring stable operation of the device in the variable marine environment.

[0039] Please see Figure 2In one embodiment of the present invention, the shaft 1 includes a cylindrical cavity 13 and two transparent covers 14, the two transparent covers 14 being connected to the two ends of the cylindrical cavity 13 respectively; the shaft 1 is coaxially arranged with the moving magnetic ring 3. The cylindrical cavity 13 is the main body of the shaft 1, and a coil winding 2 is provided inside to sense the electromotive force generated when the moving magnetic ring 3 rotates. The cylindrical cavity 13 serves as the core frame of the entire device, accommodating and protecting the internal electronic components. Two transparent covers 14 are respectively connected to the two ends of the cylindrical cavity 13. These transparent covers 14 can be made of tempered glass or other water-pressure-resistant and wear-resistant materials to ensure the waterproofness and durability of the device. The transparent covers 14 also provide windows for observing the internal working conditions. The shaft 1 is coaxially arranged with the moving magnetic ring 3 to ensure that the rotation of the moving magnetic ring 3 can smoothly cut the magnetic field lines of the coil winding 2, thereby generating an induced current in the coil winding 2, improving the power generation efficiency and the reliability of the device. In one embodiment, the cylindrical cavity 13 is made of a corrosion-resistant and wear-resistant material, preferably polytetrafluoroethylene.
