Description

Technical Field

[0001] The present invention relates to a wave power generator, and more particularly to a wave power generator that can prevent reverse rotation of an impeller and improve power generation efficiency.

Background Art

[0002] In recent years, with the increasing awareness of environmental protection, green energy power generation has been attracting attention. Typical green energy power generation includes solar power generation, wind power generation, nuclear power generation, and hydroelectric power generation.

[0003] Solar power generation mainly uses solar panels to convert light energy into electrical energy. Therefore, long hours of sunlight are required for solar power generation to generate electrical energy. However, since the surface of the solar panel has a mirror structure, when sunlight is irradiated, it may not only generate electrical energy but also cause light pollution and temperature rise in the surrounding environment due to the reflected light (in some cases, the concentrated sunlight at a single point like a magnifying glass may cause that location to become high temperature). Also, there are environmental problems regarding the treatment of used solar panels.

[0004] Wind power generation rotates blades by wind power and converts mechanical energy into electrical energy. Most existing wind turbines are built in coastal areas, and when constructing, it is necessary to consider sea conditions and climate, as well as the construction period available for ships. Also, most wind turbines are over 150 meters high (equivalent to about 50 stories), so repair and construction are not easy. In addition, the low-frequency noise generated during operation of wind turbines may cause inconvenience to surrounding residents, and the cost is also high, so there are issues with profitability.

[0005] Nuclear power generation converts mechanical energy into electrical energy by rotating a turbine to operate a generator. Its power source mainly uses energy from nuclear fission to generate steam. It is difficult for the general public to accept due to the safety of nuclear power plants, the decay period of radiation, and nuclear waste.

[0006] Hydroelectric power is a method of generating electricity by converting the potential energy of water into electrical energy. Its principle involves converting the potential energy due to the difference in water levels into kinetic energy, which then causes the water flow to rotate a turbine, operating a generator and generating electricity. However, due to recent climate change, hydroelectric power is facing the problem of water shortages, as water sources (dams, rivers, etc.) may become scarce during dry seasons. Thus, existing hydroelectric power plants face the challenge of being highly susceptible to the effects of climate change.

[0007] In summary, solar power generation faces issues such as sunlight and light pollution, wind power generation faces issues such as low-frequency noise and decreased power generation efficiency, nuclear power generation faces the problem of nuclear waste disposal, and hydroelectric power generation faces the problem of the impact of climate change.

[0008] As mentioned above, all existing green energy generation methods have shortcomings, so providing superior green energy generation equipment and devices is an urgent improvement and innovation challenge that the industry must address. [Overview of the project]

[0025] Figure 7 is a schematic diagram of a transformer unit according to an embodiment of the present invention. As shown in Figure 7, the transformer unit 20 is provided between the first pivot rod 13 and the first holder 11, and the transformer unit 20 has at least one case 200, at least one first coil 201 and at least one second coil 202, the first coil 201 and the second coil 202 are provided inside the case 200, the first coil 201 is adjacent to the second coil 202, the first coil 201 is for example a primary coil and is electrically connected to the stator unit 16, the second coil 202 is a secondary coil, the first coil 201 and the second coil 202 can exchange current, voltage or impedance, and the first coil 201 and the second coil 202 are made of iron material to conduct a magnetic field. Furthermore, the first coil 201 is electrically connected to the stator unit 16. Furthermore, the first coil 201 and the second coil 202 are each housed in two cases 200, and the two cases 200 are connected to each other by a coupling plug 203. One of the cases 200 is connected to the first holder 11, and the other case 200 is connected to the first pivot rod 13.

[0026] Referring again to Figure 1, the support bar 21 is provided between the first pivot rod 13 and the second pivot rod 14. The first pivot rod 13, the second pivot rod 14, and the support bar 21 together form an H-shaped frame, and this H-shaped frame has a reinforcing structure.

[0027] The ultraviolet unit 15 is mounted on the support bar 21 and is located between the first pivot rod 13 and the second pivot rod 14. The ultraviolet unit 15 may also be an ultraviolet light-emitting unit, and the ultraviolet unit 15 is elongated in shape.

[0028] Please refer to Figures 3 and 8. Figure 8 is a schematic diagram of a circuit according to an embodiment of the present invention. As shown in Figures 3 and 8, the stator unit 16 can be considered a power source, and the diode 30, capacitor 31, and regulator 32 supply electrical energy from the power source to the ultraviolet unit 15 by being electrically connected to the ultraviolet unit 15. The transformer unit 20 is further electrically connected to a bridge rectifier circuit 34, which is electrically connected to a second coil 202. After stabilization by the regulator 32 and rectification by the bridge rectifier 34, the electrical energy is supplied to the ultraviolet unit 15. The bridge rectifier 34 can also be further electrically connected to a connector 100, which supplies the rectified electrical energy to the connector 100. The connector 100 is electrically connected to the transformer unit 20, which supplies electrical energy from the stator unit 16 to the connector 100. The bridge rectifier 34 is waterproofed and installed inside the connector 100.

[0029] In actual use, the base 10 is installed on the shallow seabed. Since the float 182 has a floating function, the float 182 floats in a position that allows it to rotate. When a wave pushes the blade 181, the float 182 rotates, causing the rotor unit 17, which is linked to the rotation shaft 183, to rotate, and the rotor unit 17 generates electrical energy in the stator unit 16 while rotating.

[0030] The electrical energy from the stator unit 16 is conducted to the transformer unit 20 in order to transmit electrical energy to the ultraviolet unit 15 and the connector 100, respectively.

[0031] The ultraviolet unit 15 receives electrical energy from the stator unit 16 and generates ultraviolet light, which is directed towards the impeller 18 and the base 10, respectively. There are two purposes for irradiating with ultraviolet light: firstly, to prevent algae or shellfish from growing and attaching to the impeller 18 or base 10; and secondly, in the case of darkness, the warning effect of ultraviolet light informs passing ships and people that a wave power generator of the embodiment of the present invention is installed in the area where ultraviolet light is present, thereby preventing damage to the wave power generator of the present invention.

[0032] The pivot structure between the first holder 11 and the first pivot rod 13, and the pivot structure between the second holder 12 and the second pivot rod 14, allows the impeller 18 to change its position relative to the base 10 with the rise or fall of the tide. The purpose of this design is to ensure that the impeller 18 is always floating in the sea. The sizes of the first holder 11 and the first pivot rod 13, the second holder 12 and the second pivot rod 14, and the support bar 21 are adjusted based on the actual conditions and the difference between high and low tide.

[0033] Please refer to Figure 6 again. The stopper unit 19 prevents the impeller 18 from reversing when the wave recedes, because the stopper rod 1902 is pushed toward the stopper rotating disc 191 by the elastic member 1901.

[0034] Please refer again to Figures 4 and 5. The design prevents the impeller 18 from reversing, so that when the vortex-shaped elastic member 171 is struck by a wave, the rotating impeller 18 and the vortex-shaped elastic member 171 rotate significantly, and when the wave recedes, the inner end of the vortex-shaped elastic member 171 locks, and the outer end of the vortex-shaped elastic member 171 springs back, maintaining the rotor unit 17 in normal operation. Therefore, by constantly rotating the rotor unit 17 regardless of the wave direction, the power generation efficiency of the wave power generator according to the embodiment of the present invention can be increased.

[0035] The wave power generator of the present invention is an AC generator that rectifies the generated current and converts it into DC power. Therefore, multiple wave power generators can be connected using a single circuit, and the power generated by multiple wave power generators can be directly transferred to the nearest DC-to-AC power plant from the shore.

[0036] The wave power generator of the present invention can be connected using a connector 100, and the connector 100 can be a high-speed connector. Therefore, the connection can be easily disconnected during maintenance.

[0037] As described above, the wave power generator in the embodiment of the present invention may be a single unit or a plurality of units connected to each other using a circuit and connector 100. The more wave power generators there are, the greater the amount of power generated. The connector 100 has the advantage of allowing multiple or other wave power generators to be easily connected and also allowing for easy disconnection of such connections. The base 10 is installed on the seabed adjacent to the coast and is equipped with a first holder 11, a second holder 12, a transformer unit 20, a first pivot rod 13, a second pivot rod 14, an ultraviolet unit 15, a stator unit 16, a rotor unit 17, an impeller 18, and a stopper unit 19. The impeller 18 floats on the surface of the sea at both low and high tide because the float 182 is a hollow cylindrical body. The shape of the blades 181 allows the impeller 18 to capture waves, thereby enabling it to obtain maximum wave power. The stopper unit 19 restricts the turning of the impeller 18, and when the waves stop, the stopper unit 19 prevents the impeller 18 from rotating. The spiral-shaped elastic member 171 provided on the rotor unit 17 tightly wraps its inner end around the rotating shaft 183 when the impeller 18 rotates, so the stopper unit 19 can prevent the impeller 18 from rotating in the opposite direction, and the spiral-shaped elastic member 171 can also maintain the continuous rotation of the rotor unit 17, thereby maintaining the power generation efficiency of the wave power generator according to the embodiment of the present invention.

[0038] The ultraviolet unit 15 of the wave power generator of the present invention uses electrical energy generated from the wave power generator itself, so there is no need to connect an external power source. The ultraviolet rays from the ultraviolet unit 15 can prevent algae or shellfish from growing and attaching to the wave power generator of the present invention, and also have a warning effect, so that passing ships and people can be notified that a wave power generator of the embodiment of the present invention is installed in the area where the ultraviolet rays are irradiated, thereby preventing ships and people from damaging the wave power generator of the embodiment of the present invention even in the dark.

[0039] As described above, the impeller 18 of the wave power generator according to the embodiment of the present invention floats on the sea surface at both low and high tide, thus enabling it to capture a large amount of wave force. The design principle of the vortex-shaped elastic member 171 and the stopper unit 19 prevents the impeller 18 from rotating in reverse, keeping the rotor unit 17 constantly in operation, and therefore, regardless of the direction of the waves, the rotor unit 17 can maintain normal rotation. As a result, the power generation efficiency of the wave power generator according to the embodiment of the present invention is increased. Furthermore, the wave power generator according to the embodiment of the present invention allows multiple wave power generators to be connected using a single circuit, and a single wave power generator can be easily disconnected from other wave power generators, which is convenient for maintenance and, consequently, enables even more efficient power generation.
