Traditional power generation methods include: thermal power generation, hydropower generation, nuclear power, etc., but these power generation methods often have problems such as high cost (hydropower generation) and easy pollution of the environment (thermal power generation and nuclear power). Finding a clean and green power generation method has always been what people are pursuing.
[0003] Nowadays, solar power generation and wind power generation technologies have also developed to maturity, but the above two technologies are generally used on land, which is subject to many limitations and occupies a large amount of limited land resources. In the ocean, due to the driving effect of the wind, the sea water is constantly flowing and forming waves. If the kinetic energy of the waves can be utilized, it can be completely converted into electrical energy and stored and utilized. However, in the environment with large waves, the traditional wave power generation device has a high component loss rate and large losses. Summary of the invention
[0004] The purpose of the present invention is to provide a power generation platform for solving the above technical problems.
[0005] The power generation platform described in the present application includes a platform and a wave energy power generation device, wherein the wave energy power generation device is arranged on the platform, and the wave energy power generation device includes a floating body, a first connecting member, a second connecting member and a wave energy generator, wherein the wave energy generator includes a mover and a stator, wherein the stator is fixed on the platform, wherein the mover is movably connected to the stator, wherein the mover is connected to one end of the first connecting member, and wherein the floating body is connected to the other end of the first connecting member through the second connecting member, and wherein the second connecting member is a flexible connecting member.
[0006] Wherein, the first connecting member is a steel column structure, and the first connecting member is rigidly connected to the mover.
[0007] Wherein, the diameter of the first connecting member matches the diameter of the channel through which the mover moves in the stator.
[0008] There are three wave energy power generation devices, and the three wave energy power generation devices are distributed in a triangular field structure.
[0009] The power generation platform further comprises a wind power generation device, which comprises a vertical pole, a wind wheel and a wind generator. The vertical pole stands on the platform, the wind generator is arranged at the top of the vertical pole, and the wind wheel is connected to the wind generator.
[0010] Wherein, the wind wheel comprises a large wind wheel and a small wind wheel, the large wind wheel and the small wind wheel are arranged opposite to each other at two ends of the wind turbine, and the axial direction of the large wind wheel and the small wind wheel is perpendicular to the vertical pole.
[0011] Wherein, the length of the blades of the large wind wheel is 2 to 4 times the length of the blades of the small wind wheel.
[0012] Wherein, the power generation platform also includes a solar power generation device, and the solar power generation device includes a solar panel, and the solar panel is arranged on the vertical pole.
[0013] The solar panel is a U-shaped structure, the solar panel is connected to the vertical pole at an angle, and the position of the solar panel relative to the vertical pole is adjustable.
[0014] Wherein, the solar panel is a ring-like structure with through holes, and the solar panel is sleeved on the vertical pole.
[0015] When using the power generation platform described in the present application, since the power generation platform has three types of power generation devices, namely wind power generation devices, solar power generation devices and wave power generation devices, the three types of power generation devices can provide complementary electric energy to each other, making the power generation performance of the power generation platform more stable. And since the power generation platform can simultaneously carry out three types of power generation methods, namely wind power generation, solar power generation and wave power generation, the power generation efficiency of the power generation platform is higher. In addition, the floating body is flexibly connected to the first connecting member through the second connecting member. When the waves are large, the force of the waves on the floating body exceeds the bearing capacity of the second connecting member, the second connecting member will be disconnected, and the first connecting member and the mover will sink into the platform instead of leaving the platform together with the floating body, thereby reducing the component loss rate and reducing losses.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] Please also read Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of a power generation platform 100 provided in an embodiment of the present application.
[0027] Figure 2 is used Figure 1 A schematic structural diagram of a wave energy power generation device 40 in a power generation platform 100 is shown.
[0028] The power generation platform 100 provided in the embodiment of the present application includes a platform 10 and a wind power generation device 20, a solar power generation device 30 and a wave power generation device 40 arranged on the platform 10. The wind power generation device 20 includes a vertical pole 21, a wind wheel 22 and a wind generator 23. The vertical pole 21 stands on the platform 10. The wind generator 23 is arranged at the top of the vertical pole 21. The wind wheel 22 is connected to the wind generator 23. The solar power generation device 30 includes a solar panel 31, which is arranged on the vertical pole 21. The wave power generation device 40 includes a floating body 41, a first connecting member 42, a second connecting member 43 and a wave power generator 44. The wave power generator 44 includes a mover 441 and a stator 442. The stator 442 is fixed on the platform 10. The mover 441 is movably connected to the stator 442. The mover 441 is connected to one end of the first connecting member 42. The floating body 41 is connected to the other end of the first connecting member 42 through the second connecting member 43. The second connecting member 43 is a flexible connecting member.
[0029] When using the power generation platform 100 provided in the embodiment of the present application, since the power generation platform 100 has three types of power generation devices, namely, a wind power generation device 20, a solar power generation device 30, and a wave power generation device 40, the three types of power generation devices can provide complementary electric energy to each other, making the power generation performance of the power generation platform 100 more stable. And since the power generation platform 100 can simultaneously perform three types of power generation methods, namely, wind power generation, solar power generation, and wave power generation, the power generation efficiency of the power generation platform 100 is higher. In addition, the floating body 41 is flexibly connected to the first connecting member 42 through the second connecting member 43. When the waves are large, the force of the waves on the floating body 41 exceeds the bearing capacity of the second connecting member 43, the second connecting member 43 will be disconnected, and the first connecting member 42 and the mover 441 will sink into the platform 10, instead of leaving the platform 10 together with the floating body 41, thereby reducing the component loss rate and reducing losses.
[0030] The wave energy power generation device 40 is arranged on the platform 10, including a floating body 41, a first connecting member 42, a second connecting member 43 and a wave energy generator 44, wherein the wave energy generator 44 includes a mover 441 and a stator 442, the floating body 41 is connected to one end of the first connecting member 42 through the second connecting member 43, and the mover 441 is connected to the other end of the first connecting member 42. When the wave energy power generation device 40 is placed in the sea, with the rise and fall of waves, the floating body 41 will reciprocate relative to the platform 10 in a direction perpendicular to the platform 10, thereby driving the first connecting member 42, the second connecting member 43 and the mover 441 to reciprocate together. Since the stator 442 is fixed on the platform 10, the mover 441 will reciprocate relative to the stator 442. In a specific embodiment, the wave energy generator 44 is a permanent magnet linear generator, and the mover 441 reciprocates in the stator 442 to cut the magnetic flux lines, thereby achieving the purpose of wave energy generation. It should be noted that the wave energy generator 44 includes but is not limited to a permanent magnet linear generator, and can be any other type of generator that meets the functional requirements.
[0031] It is understandable that the operating environment of the wave energy power generation device 40 includes but is not limited to the sea, and can also be in a river, a stream or any environment with liquid waves. In any of the above operating environments, the wave energy power generation device 40 can meet the wave energy power generation function requirements.
[0032] In one embodiment, the second connecting member 43 is a flexible connecting member, that is, the float 41 and the first connecting member 42 are flexibly connected through the second connecting member 43, wherein the second connecting member 43 has a certain bearing capacity and can meet normal working requirements. That is to say, in a normal wave environment, the force exerted by the float 41 on the second connecting member 43 is less than the bearing capacity of the second connecting member 43 itself, and the second connecting member 43 can meet the requirements of connecting the float 41 and the first connecting member 42.
[0033] When the waves are too large, the waves will exert a large force on the floating body 41 in the direction perpendicular to the platform 10, which can easily cause the floating body 41 to separate from the power generation platform 100. For the traditional wave power generation device 40, the floating body 41 will drive the connecting member and the mover 441 to separate from the platform 10, which increases the component loss rate. In addition, since the cost of the mover 441 is generally high, the loss of the mover 441 causes a large economic loss. When using the power generation platform 100 provided by the embodiment of the present application, since the second connecting member 43 in the wave power generation device 40 is a flexible connecting member, when the force exerted by the waves on the floating body 41 is too large, the force exerted by the floating body 41 on the second connecting member 43 exceeds the bearing capacity of the second connecting member 43 itself, and the second connecting member 43 will be disconnected, so that the floating body 41 is separated from other components, and the first connecting member 42 and the mover 441 will sink into the stator 442, and will not separate from the platform 10 with the floating body 41, thereby ensuring that the mover 441 will not be lost, reducing the component loss rate and reducing losses. In a specific embodiment, the second connecting member 43 is a steel rope. It can be understood that the second connecting member 43 includes but is not limited to a steel rope and can be any flexible connecting structure that meets functional requirements.
[0034] In one embodiment, the first connector 42 is a rigid connector, that is, a rigid connection is made between the mover 441 and the first connector 42. Since the first connector 42 is connected to the mover 441, when the floating body 41 drives the first connector 42 to move through the second connector 43, the first connector 42 drives the mover 441 to move together, and since the first connector 42 and the mover 441 are rigidly connected, the movement of the mover 441 is stable and less affected by inertia, thereby making the power generation effect of the wave energy power generation device 40 stable and good.
[0035] It can be understood that since the first connecting member 42 is a rigid connecting member, it has a certain weight. When the waves are large and the second connecting member 43 is disconnected, the first connecting member 42 will drive the mover 441 to sink rapidly under the action of gravity, thereby preventing the mover 441 from detaching from the platform 10, reducing the component loss rate and minimizing losses.
[0036] In one embodiment, the first connecting member 42 is a steel column structure, that is, the mover 441 is rigidly connected to the steel column structure, and the diameter of the first connecting member 42, that is, the diameter of the steel column structure, matches the diameter of the channel in which the mover 441 moves in the stator 442. In other words, when the steel column structure moves in the channel in the stator 442, it will only reciprocate along the direction of the channel without performing additional tilting and offsetting movements. Therefore, the mover 441 connected thereto will also only reciprocate along the direction of the stator 442 channel without performing additional tilting and offsetting movements, thereby avoiding the influence of the movement angle and making the power generation efficiency higher.
[0037] Please also read Figure 3 , Figure 3 It is a top view of the triangular field structure of the wave energy power generation device 40.
[0038] In one embodiment, the power generation platform 100 is provided with three wave energy power generation devices 40, and the three wave energy power generation devices 40 are distributed in a triangular field structure. When the wave energy power generation devices 40 are distributed in a triangular field structure, the wave energy power generation devices 40 have a higher absorption rate of wave energy, which improves the power generation efficiency to a certain extent, and under this structure, the wave energy power generation devices 40 are less affected by hydrodynamic forces, which further improves the stability of the power generation operation.
[0039] In one embodiment, the wind power generation device 20 is arranged at the center of the above-mentioned triangular field structure, that is, the vertical pole 21 of the wind power generation device 20 is located at the symmetric center of the above-mentioned three wave power generation devices 40. It can be understood that in the process of the wave power generation device absorbing wave energy and converting it into electrical energy, each wave power generation device 40 will produce a certain vibration, and the three wave power generation devices 40 will all produce a certain vibration effect on the wind power generation device 20. Under the above-mentioned structural distribution, since the wave power generation devices 40 are evenly distributed around the wind power generation device 20, the above-mentioned vibration effects will have a certain offset effect on each other, so that the vibration effect on the wind power generation device 20 is reduced, the power generation efficiency of the wind power generation device 20 is improved to a certain extent, and the service life of the wind power generation device 20 is extended.
[0040] Please also read Figure 4 , Figure 4 yes Figure 1 A side view of a wind power generation device 20 in a power generation platform 100 is shown.
[0041] In the power generation platform 100 provided in the embodiment of the present application, the wind power generation device 20 includes a vertical pole 21, a wind wheel 22 and a wind generator 23, wherein the wind generator 23 is arranged at the top of the vertical pole 21, and the wind wheel 22 is connected to the wind generator 23. The wind wheel 22 rotates under the action of wind force, thereby driving the wind generator 23 to generate electricity. In a specific embodiment, the wind generator 23 is a horizontal axis permanent magnet synchronous generator. It should be noted that the wind generator 23 includes but is not limited to a horizontal axis permanent magnet synchronous generator, and can also be any other type of generator that meets the functional requirements.
[0042] In one embodiment, the wind wheel 22 includes a large wind wheel 221 and a small wind wheel 222. The blade length of the large wind wheel 221 is greater than the blade length of the small wind wheel 222. The large wind wheel 221 and the small wind wheel 222 are arranged opposite to each other at two ends of the wind generator 23, and the axial direction of the large wind wheel 221 and the small wind wheel 222 is perpendicular to the vertical pole 21.
[0043] It should be noted that in process design and production, due to errors or limitations in process level, the verticality in the embodiment of the present application may not be strictly perpendicular to each other, that is, the angle between the axial direction of the large wind wheel 221 and the small wind wheel 222 and the direction of the vertical pole 21 is close to 90°, but not 90°. However, the angle error between these two directions in the power generation platform 100 provided in the embodiment of the present application due to the process should be acceptable to technicians in this field, and the angle should not affect the realization of the purpose of the embodiment of the present application.
[0044] When the wind force in the environment where the power generation platform 100 is located is relatively small, the wind force is too small to rotate the large wind wheel 221. At this time, the wind power generation device 20 can be switched to the power generation mode of the small wind wheel 222, and wind power generation is performed by rotating the small wind wheel 222, thereby ensuring the power generation stability of the wind power generation device 20. It can be understood that when the wind force in the environment is relatively small, the small wind wheel 222 can also be used as an excitation source for the operation of the large wind wheel 221, that is, the operation of the small wind wheel 222 drives the large wind wheel 221 to start operating, and then the large wind wheel 221 can continue to operate through inertia and the action of a small amount of wind force, thereby ensuring the stability of the power generation operation. At the same time, the large wind wheel 221 and the small wind wheel 222 can also operate at the same time, and the rotational motion direction of the two is the same, and they jointly drive the wind turbine 23 to generate electricity, thereby improving the power generation efficiency.
[0045] In one embodiment, the wind power generation device 20 also includes an internal control circuit (not shown). When the wind power generation device 20 is working normally, the internal control circuit can store a portion of the electrical energy. When the wind force in the environment where the power generation platform 100 is located is too strong, the large wind wheel 221 operates at high speed and is easily in an overload state, which will cause damage to the structure of the large wind wheel 221 and reduce the service life of the wind power generation device 20. At this time, the internal control circuit can output the stored electrical energy, control the small wind wheel 222 to rotate in the opposite direction, or increase the resistance of the small wind wheel 222 to the large wind wheel 221 in other ways, so that the rotation speed of the large wind wheel 221 is reduced and it is out of the overload state, thereby protecting the large wind wheel 221 from damage and increasing the service life of the wind power generation device 20. In one embodiment, the length of the blades of the large wind wheel 221 is 2 to 4 times the length of the blades of the small wind wheel 222. Under this structural size, the large wind wheel 221 and the small wind wheel 222 can effectively meet the corresponding functional requirements, and the structure of the wind power generation device 20 formed is stable. In a specific embodiment, the length of the blades of the large wind wheel 221 is 3 times the length of the blades of the small wind wheel 222. It can be understood that the wave power generation device 40 and the solar power generation device 30 can both transmit electrical energy to the wind power generation device 20 through the internal control circuit to jointly achieve complementary power generation.
[0046] Among them, the large wind wheel 221 and the small wind wheel 222 are both made of fiberglass or carbon fiber materials. The wind wheel 22 made of the above materials has the characteristics of high strength and light weight, so that the large wind wheel 221 and the small wind wheel 222 can operate better and improve the performance of the wind power generation device 20. It can be understood that the materials for making the wind wheel 22 include but are not limited to fiberglass or carbon fiber materials, and can be any other materials that meet the functional requirements, which will not be described one by one here.
[0047] Please also read Figures 5 to 8 , Figure 5 yes Figure 1 A top view of the connection between the solar power generation device 30 and the pole 21 in the power generation platform 100 in one embodiment is shown.
[0048] Figure 6 yes Figure 5 The solar power generation device 30 is shown in a side view of the connection with the pole 21 .
[0049] Figure 7 yes Figure 1 A top view of the connection between the solar power generation device 30 and the pole 21 in the power generation platform 100 in another embodiment is shown.
[0050] Figure 8 yes Figure 7 The solar power generation device 30 is shown in a side view of the connection with the pole 21 .
[0051] In the power generation platform 100 provided in the embodiment of the present application, there is a solar power generation device 30 including a solar panel 31, which is used to convert solar energy into electrical energy to perform solar power generation. The solar panel 31 can be set on the pole 21 of the wind power generation device. Since the pole 21 is relatively high, setting the solar panel 31 on the pole 21 can better absorb light energy, which is conducive to improving the working efficiency of the solar power generation device 30.
[0052] In one embodiment, the solar panel 31 is a U-shaped structure, the solar panel 31 is arranged on the pole 21, the solar panel 31 is connected to the pole 21 at an angle, and the position of the solar panel 31 relative to the pole 21 is adjustable. When the solar panel 31 is a U-shaped structure, its U-shaped notch can be better connected and fixed to the pole 21, and the U-shaped structure of the solar panel 31 increases the illumination area of the solar panel 31 to a certain extent. It can be understood that the angle of illumination is different depending on the difference between the northern and southern hemispheres and the different seasons. The angle between the solar panel 31 and the pole 21, as well as the orientation and height position of the solar panel 31 can be adjusted so that the solar panel 31 has a larger illumination area, thereby improving the power generation efficiency.
[0053] In one embodiment, the solar panel 31 is a ring-like structure with a through hole, and the solar panel 31 is sleeved on the vertical pole 21. When the solar panel 31 is a ring-like structure and sleeved on the vertical pole 21, the solar panel 31 is suitable for sunlight irradiation at any angle, and there is no need to adjust the direction of the solar panel 31, which saves labor costs and improves the power generation efficiency of the solar power generation device 30. It can be understood that when the ring-like solar panel 31 is sleeved on the vertical pole 21, it can also be connected to the vertical pole 21 at a certain angle.
[0054] When the power generation platform 100 provided in the embodiment of the present application is used for power generation, since the power generation platform 100 has three types of power generation devices, namely, a wind power generation device 20, a solar power generation device 30, and a wave power generation device 40, the three types of power generation devices can provide complementary electric energy to each other, making the power generation performance of the power generation platform 100 more stable. And since the power generation platform 100 can simultaneously perform three types of power generation methods, namely, wind power generation, solar power generation, and wave power generation, the power generation efficiency of the power generation platform 100 is higher. In addition, the floating body 41 is flexibly connected to the first connecting member 42 through the second connecting member 43. When the waves are large, the force of the waves on the floating body 41 exceeds the bearing capacity of the second connecting member 43, the second connecting member 43 will be disconnected, and the first connecting member 42 and the mover 441 will sink into the platform 10, instead of leaving the platform 10 together with the floating body 41, thereby reducing the component loss rate and reducing losses.
[0055] The technical features of the above-mentioned embodiments may be arbitrarily combined. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
