Description

Technical Field

[0001] This invention relates to a power generation device, and more particularly to a multi-axis wave power generation device that is highly mobile and provides stable power generation. Background Technology

[0002] Wave power generation, as the name suggests, converts wave energy into electrical energy. Although wave energy is unstable and unpredictable, its near-inexhaustible nature makes wave power generation one of the most promising methods of ocean energy generation. However, existing wave power generation devices cannot withstand the strong winds and heavy rains brought by typhoons and have poor mobility. Therefore, a large amount of manpower and resources must be spent on implementing corresponding typhoon prevention measures before a typhoon strikes to avoid damage to the wave generators. In addition, most existing wave power generation devices cannot be adjusted according to environmental conditions, resulting in relatively unstable power generation. Summary of the Invention

Then, by moving the carrier, the multi-axis wave generator can be moved to a safe location, thus avoiding damage. Furthermore, the lifting mechanism of this invention can not only be used to adjust the angle between the cantilever and the main body but also for generating electricity. Therefore, the multi-axis wave generator of this invention has the advantages of high mobility, excellent environmental adaptability, and stable power generation. Attached Figure Description

[0091] The directional terms used in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. Furthermore, unless otherwise specified, the terms "coupled" or "connected" herein include any direct or indirect electrical or structural connection means. Therefore, if the text describes a first device coupled / connected to a second device, it means that the first device can be directly electrically / structurally connected to the second device, or indirectly electrically / structurally connected to the second device through other devices or connection means.

[0092] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the multi-axis wave power generation device 1 according to the first embodiment of the present invention. Figure 2 This is a functional block diagram of the multi-axis wave power generation device 1 according to the first embodiment of the present invention. Figure 1 and Figure 2As shown, the multi-axis wave power generation device 1 includes a carrier 11, a main body 12, and a wave generator set 13. The main body 12 is coupled to the carrier 11, and the wave generator set 13 is coupled to the main body 12. The wave generator set 13 includes at least one generator 131, a cantilever 132, and a drive unit 133. In this embodiment, the wave generator set 13 includes a permanent magnet generator 1311 disposed between the cantilever 132 and the drive member 133, and a hydraulic generator 1312 disposed between the permanent magnet generator 1311 and the cantilever 132. When the wave drives the drive member 133 to move relative to the cantilever 132, the movement of the drive member 133 relative to the cantilever 132 can drive the permanent magnet generator 1311 and the hydraulic generator 1312 to generate electricity. The rotor of the permanent magnet generator 1311 is coupled to the drive member 133, and the stator of the permanent magnet generator 1311 is coupled to the cantilever 132 and can rotate relative to the cantilever 132 about a second rotating shaft R2. The second rotating shaft R2 is different from the first rotating shaft R1 around which the rotor of the permanent magnet generator 1311 rotates relative to the stator. Preferably, the second rotating shaft R2 can be perpendicular to the first rotating shaft R1. Furthermore, the piston of the hydraulic generator 1312 is coupled to the stator of the permanent magnet generator 1311, and the hydraulic cylinder of the hydraulic generator 1312 is coupled to the cantilever 132. Thus, when the wave-driven drive member 133 drives the rotor of the permanent magnet generator 1311 to rotate relative to the stator around the first rotating shaft R1, the change in magnetic flux caused by the rotation of the rotor of the permanent magnet generator 1311 relative to the stator around the first rotating shaft R1 enables the permanent magnet generator 1311 to generate electricity. When the wave-driven drive member 133 drives the stator of the permanent magnet generator 1311 to rotate relative to the cantilever 132 around the second rotating shaft R2, the rotation of the stator of the permanent magnet generator 1311 relative to the cantilever 132 around the second rotating shaft R2 drives the piston to move relative to the hydraulic cylinder, thereby pushing the hydraulic oil so that the hydraulic generator 1312 can generate electricity.

[0093] However, the present invention is not limited to this embodiment, and its implementation depends on actual needs. For example, in another embodiment, the wave generator set may include only one permanent magnet generator disposed between the cantilever and the drive member. Alternatively, in another embodiment, the wave generator set may include only one permanent magnet generator or one hydraulic generator disposed between the cantilever and the main body, so that the movement of the cantilever relative to the main body can drive the permanent magnet generator or the hydraulic generator to generate electricity.

[0094] In this embodiment, the vehicle 11 is a wheeled vehicle; however, the invention is not limited to this embodiment. For example, the vehicle may also be a tracked vehicle or a rail-mounted vehicle.

[0095] Furthermore, such as Figure 1 and Figure 2As shown, the multi-axis wave power generation device 1 also includes a rotating mechanism 14, two lifting mechanisms 15, and a control unit 16. The rotating mechanism 14 is coupled between the carrier 11 and the main body 12 and is used to drive the main body 12 to rotate relative to the carrier 11 about a vertical axis A1, so as to adjust the direction of the cantilever 132 relative to the carrier 11. The two lifting mechanisms 15 are located on both sides of the cantilever 132, and each lifting mechanism 15 is coupled between the cantilever 132 and the main body 12 and is used to drive the cantilever 132 to rotate relative to the main body 12 about a horizontal axis A2, so as to adjust the angle between the cantilever 132 and the main body 12. The control unit 16 is electrically connected to the rotating mechanism 14 and each lifting mechanism 15. The control unit 16 is used to control the rotating mechanism 14 to drive the main body 12 to rotate relative to the carrier 11 about a vertical axis A1 and / or control the two lifting mechanisms 15 to drive the cantilever 132 to rotate relative to the main body 12 about a horizontal axis A2.

[0096] However, the number of lifting mechanisms in this invention is not limited to this. For example, in another embodiment, the multi-axis wave power generation device may include only one lifting mechanism located on one side of the cantilever.

[0097] Preferably, the control unit 16 can control the rotating mechanism 14 to drive the main body 12 to rotate relative to the carrier 11 about the vertical axis A1 according to the wind direction, wave direction or power generation. The control unit 16 can also control the two lifting mechanisms 15 to drive the cantilever 132 to rotate relative to the main body 12 about the horizontal axis A2 according to the wave height, tide level or power generation. That is, the control unit 16 can include at least one sensor 161 and a control circuit 162. The at least one sensor 161 can be used to sense the wind direction, wave direction, wave height, tide level and / or power generation. The control circuit 162 controls the rotating mechanism 14 and / or the two lifting mechanisms 15 according to the sensing results of the at least one sensor 161.

[0098] Understandably, in another embodiment, the control unit may obtain information such as wind direction, wave direction, wave height, tide level and / or power generation by other means, for example, by connecting to a meteorological bureau or marine meteorological data buoy station via the Internet to download the required relevant information.

[0099] Specifically, the rotating mechanism 14 includes a turntable 141 and a drive assembly 142. The drive assembly 142 is coupled between the turntable 141 and the carrier 11 and is used to drive the turntable 141 to rotate relative to the carrier 11 about a vertical axis A1. The drive assembly 142 is electrically connected to the control unit 16, which controls the drive assembly 142 to drive the turntable 141 to rotate relative to the carrier 11 about a vertical axis A1. In this embodiment, the turntable 141 is fixedly coupled to the main body 12 and rotatably coupled to the carrier 11, so that when the control unit 16 controls the drive assembly 142 to drive the turntable 141 to rotate relative to the carrier 11 about a vertical axis A1, the main body 12 rotates together with the turntable 141 relative to the carrier 11 about a vertical axis A1.

[0100] However, the present invention is not limited to this embodiment, and its configuration depends on actual needs. The turntable is rotatably coupled to one of the main body and the carrier and fixedly coupled to the other of the main body and the carrier. For example, in another embodiment, the turntable is fixedly coupled to the carrier and rotatably coupled to the main body, a drive assembly is coupled between the turntable and the main body, and a control unit is used to control the drive assembly to drive the relative rotation of the turntable and the main body.

[0101] Preferably, in this embodiment, the drive assembly 142 may include a motor 1421 and a reducer 1422. The reducer 1422 may be a gear reducer or a belt reducer. However, the present invention is not limited to this embodiment. For example, in another embodiment, the drive assembly may also drive the turntable to rotate in a pneumatic or hydraulic manner.

[0102] Furthermore, the control circuit 162 of the control unit 16 can be used to switch the two lifting mechanisms 15 between driving mode and power generation mode. When the two lifting mechanisms 15 are in driving mode, they can be used to drive the cantilever 132 to rotate relative to the main body 12 around the horizontal axis A2. When the two lifting mechanisms 15 are in power generation mode, they can be used to generate electricity.

[0103] Specifically, please refer to Figures 1 to 3 , Figure 3 This is a pipeline and instrumentation diagram of the lifting mechanism 15 according to the first embodiment of the present invention. Figures 1 to 3As shown, each lifting mechanism 15 includes a hydraulic energy conversion component 151, an electric generator 152, a hydraulic cylinder 153, a piston 154, an oil tank 155, and an oil circuit system 156. The electric generator 152 is coupled to the hydraulic energy conversion component 151. The hydraulic energy conversion component 151 can be used as a hydraulic pump to convert mechanical energy into hydraulic energy to drive fluid flow. The hydraulic energy conversion component 151 can also be used as a hydraulic motor to convert hydraulic energy into mechanical energy to be driven by fluid. The hydraulic cylinder 153 is coupled to the main body 12. The piston 154 is movably disposed in the hydraulic cylinder 153 to divide the hydraulic cylinder 153 into a first chamber 1531 and a second chamber 1532. The piston 154 is coupled to the cantilever 132. The oil tank 155 contains hydraulic oil. The oil circuit system 156 is used to transport hydraulic oil. When the lifting mechanism 15 is in drive mode, the control unit 16 can drive the electric generator 152 to drive the hydraulic energy conversion component 151 to deliver hydraulic oil through the oil circuit system 156 to one of the first chamber 1531 and the second chamber 1532. When the hydraulic oil is delivered to one of the first chamber 1531 and the second chamber 1532 through the oil circuit system 156, the piston 154 is pushed by the hydraulic oil and moves toward the other of the first chamber 1531 and the second chamber 1532, so that the piston 154 extends or retracts in the hydraulic cylinder 153, thereby causing the piston 154 to drive the cantilever 132 to rotate along the first rotation direction D1 to increase the angle between the cantilever 132 and the main body 12, or to drive the piston 154 to drive the cantilever 132 to rotate along the second rotation direction D2 opposite to the first rotation direction D1 to decrease the angle between the cantilever 132 and the main body 12. When the lifting mechanism 15 is in the power generation mode, the control unit 16 may not drive the electric generator 152 to drive the hydraulic energy conversion component 151. At this time, the piston 154 can be driven by the rotation of the cantilever 132 relative to the main body 12 around the horizontal axis A2. When the piston 154 is driven to move towards one of the first chamber 1531 and the second chamber 1532 and the hydraulic oil is transported through the oil circuit system 156 to the other of the first chamber 1531 and the second chamber 1532, the hydraulic energy conversion component 151 is driven by the hydraulic oil to drive the electric generator 152 to generate electricity.

[0104] More specifically, the hydraulic system 156 also includes a first fitting 1561, a first switching valve 1562, a second fitting 1563, a three-position four-way directional valve 1564, a third fitting 1565, a second switching valve 1566, a fourth fitting 1567, a fifth fitting 1568, a third switching valve 1569, a sixth fitting 156A, a seventh fitting 156B, an eighth fitting 156C, a ninth fitting 156D, a tenth fitting 156E, an eleventh fitting 156F, and a twelfth fitting 156G. The first fitting 1561 connects to the hydraulic energy conversion assembly 151 and the oil tank 155; the second fitting 1563 connects to the first switching valve 1562 and the hydraulic energy conversion assembly 151; the third fitting 1565 connects to the three-position four-way directional valve 1564 and the first switching valve 1562; and the fourth fitting 1567 connects to... The second switching valve 1566 is connected to the three-position four-way directional valve 1564. The fifth pipe 1568 is connected between the second chamber 1532 and the second switching valve 1566. The sixth pipe 156A is connected between the third switching valve 1569 and the first chamber 1531. The seventh pipe 156B is connected between the three-position four-way directional valve 1564 and the third switching valve 1569.

[0115] In summary, in this invention, the multi-axis wave generator can utilize a rotating mechanism to rotate the main body relative to the carrier around a vertical axis, adjusting the direction of the cantilever relative to the carrier, according to environmental conditions. Furthermore, a lifting mechanism is used to rotate the cantilever relative to the main body around a horizontal axis perpendicular to the vertical axis, adjusting the angle between the cantilever and the main body. This allows the multi-axis wave generator to generate electricity stably. Moreover, before a typhoon strikes, the user can adjust the direction of the cantilever relative to the carrier and the angle between the cantilever and the main body to move the wave generator above sea level. Then, by moving the carrier, the multi-axis wave generator can be moved to a safe location, thus avoiding damage. Furthermore, the lifting mechanism of this invention can not only be used to adjust the angle between the cantilever and the main body but also to generate electricity. Therefore, the multi-axis wave generator of this invention has the advantages of high mobility, excellent environmental adaptability, and stable power generation.
