The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
In at least one embodiment, the power generation system 100 includes a power generation unit 10, a water energy unit 20, and a wind energy unit 30. The water energy unit 20 includes an output end (not shown), and the wind energy unit 30 includes an output end (not shown).
The power generation unit 10 includes a first power generation module 11 and a second power generation module 12. The first power generation module 11 includes an input end (not shown), and the second power generation module 12 includes an input end (not shown).
The output end of the water energy unit 20 is connected to the input end of the first power generation module 11, to drive the first power generation module 11 to rotate. The output end of the wind energy unit 30 is connected to the input end of the second power generation module 12, to drive the second power generation module 12 to rotate.
When the rotational speed of the first power generation module 11 is faster than the rotational speed of the second power generation module 12, the first power generation module 11 can be regarded as rotor of a generator, and the second power generation module 12 can be regarded as stator of a generator.
When the rotational speed of the first power generation module 11 is slower than the rotational speed of the second power generation module 12, the first power generation module 11 can be regarded as stator of a generator, and the second power generation module 12 can be regarded as rotor of a generator.
In one embodiment, the direction of rotation of the output end of the water energy unit 20 is opposite to the direction of rotation of the output end of the wind energy unit 30. The first power generation module 11 and the second power generation module 12 are thus rotated in opposite directions to cut the magnetic induction line, to generate the desired electricity. Mechanical energy is thus converted into electrical energy.
In at least one embodiment, the power generation system 100 further includes a frame 40. The frame 40 includes a base 41, a first supporting portion 42, and a second supporting portion 43. The first supporting portion 42 is fixed between the base 41 and the second supporting portion 43.
In the embodiment, the base 41 is disposed on sea floor, and the first supporting portion 42 is submerged in sea water. The second supporting portion 43 is extended out over the surface of sea or ocean. In another embodiment, the frame 40 may be installed in another water environment, such as a river.
The wind energy unit 30 and the power generation unit 10 may be disposed at the top of the frame 40. The water energy unit 20 may be disposed on the frame 40, the water energy unit 20 is located below the wind energy unit 30 and the power generation unit 10.
In the embodiment, the water energy unit 20 includes a water blade 21 and a turbine housing or container (turbine cabin 24), and the wind energy unit 30 includes a wind blade 31 and a turbine housing or container (turbine cabin 34). The power generation unit 10 is installed in the turbine cabin 34.
A first transmission mechanism 22 is installed in the turbine cabin 24, and a second transmission mechanism 32 is installed in the turbine cabin 34. The first transmission mechanism 22 includes an input end (not shown) and an output end (not shown). The second transmission mechanism 32 includes an input end (not shown) and an output end (not shown).
The water blade 21 is disposed in front of the turbine cabin 24, and the turbine cabin 24 is rotatably coupled to the first supporting portion 42. The wind blade 31 is disposed in front of the turbine cabin 34, and the turbine cabin 34 is rotatably coupled to the second supporting portion 43.
The water blade 21 is submerged below the surface of the water, and the wind energy unit 30 protrudes above the surface of the water.
In the embodiment, the frame 40 is further provided with a through hole (not shown) which penetrates the first supporting portion 42 and the second supporting portion 43. The water blade 21 is connected to the input end of the first transmission mechanism 22 through an axle (not shown). The output end of the first transmission mechanism 22 passes through the through hole and is connected to the input end of the first power generation module 11.
The wind blade 31 is connected to the input end of the second transmission mechanism 32 through an axle (not shown). The output end of the second transmission mechanism 32 is connected to the input end of the second power generation module 12. In the embodiment, the first transmission mechanism 22 and the second transmission mechanism 32 may include gears.
The water energy unit 20 further includes a first detection element 23, and the wind energy unit 30 further includes a second detection element 33.
The first detection element 23 is installed on the turbine cabin 24, and the second detection element 33 is installed on the turbine cabin 34.
The first detection element 23 detects the direction of water flow, flow rate, and other conditions relating to the water blade 21 in real time.
The second detection element 33 detects the wind flow direction, wind speed, and other related conditions relating to the wind blade 31 in real time.
In at least one embodiment, the power generation system 100 further includes a first rotation mechanism 50 and a second rotation mechanism 60.
The first rotation mechanism 50 is fixed to the turbine cabin 24, and the first supporting portion 42 is rotatably coupled to the first rotation mechanism 50. The second rotation mechanism 60 is fixed to the turbine cabin 34, and the second supporting portion 43 is rotatably coupled to the second rotation mechanism 60. Therefore, the first rotation mechanism 50 and the second rotation mechanism 60 can be rotated by the frame 40 on a central axis.
The power generation system 100 further includes a control unit 70. The control unit 70 is installed in the turbine cabin 34.
The control unit 70 communicates with the first detection element 23 and the first rotation mechanism 50. The control unit 70 obtains the water flow direction from the first detection element 23, and controls rotation of the first rotation mechanism 50 according to the water flow direction, so that the water blade 21 can efficiently face the water.
The control unit 70 outputs a first control signal according to the water flow direction, to establish a transmission connection between the first rotation mechanism 50 and the first transmission mechanism 22. Therefore, the first rotation mechanism 50 can rotate under the transmission of the first transmission mechanism 22, thereby driving the turbine cabin 24 and the water blade 21 to rotate with the frame 40 on a central axis.
The control unit 70 can communicate with the second detection element 33 and the second rotation mechanism 60. The control unit 70 obtains the wind flow direction from the second detection element 33, and controls the rotation of the second rotation mechanism 60 according to the wind flow direction, so that the wind blade 31 can face the wind in an efficient way.
The control unit 70 outputs a second control signal according to the wind flow direction, to establish a transmission connection between the second rotation mechanism 60 and the second transmission mechanism 32. Therefore, the second rotation mechanism 60 can rotate under the transmission of the second transmission mechanism 32, thereby driving the turbine cabin 34 and the wind blade 31 to rotate with the frame 40 on a central axis.
The control unit 70 controls the rotation of the first rotation mechanism 50 and the second rotation mechanism 60 to adjust the respective orientations of the turbine cabin 24 and the turbine cabin 34, such that the water blade 21 and the wind blade 31 face the water and the wind respectively in the most efficient manner possible.
In at least one embodiment, the power generation system 100 further includes a data unit 80 and a power unit 90. The data unit 80 and the power unit 90 are installed in the turbine cabin 34.

The data unit 80 provides weather data for the control unit 70, the weather data may be temperature, air pressure, wind speed, and flow rate. The control unit 70 can adjust the orientations of the water blade 21 and the wind blade 31 according to the weather data.
The power unit 90 is electrically coupled between the power generation unit 10 and the control unit 70. The power unit 90 is also electrically coupled to an external power system (not shown). The power unit 90 passes on the electrical power generated by the power generation unit 10 to the control unit 70 and the external power system.
