[0052] The embodiment of the present invention provides a power generation device integrating a multi-module anti-rolling wave energy device, which is used to solve the technical problem of poor anti-rolling effect of the existing power generation platform.
[0053] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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.
[0054] See also Figures 1 to 10 The present invention provides a multi-module anti-roll wave energy device integrated power generation device, comprising a floating platform 1, a plurality of rotating flap mechanisms 2, a heave type power generation mechanism 3 and an oscillating type power generation mechanism 4;
[0055] A plurality of rotating flap mechanisms 2 are arranged on the peripheral side of the floating platform 1, and the rotating flap mechanism 2 has a rotating part 20, and the rotating part 20 is rotatably mounted on the floating platform 1;
[0056] The vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 are both arranged at the bottom of the floating platform 1, and the vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 are arranged up and down. The vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 are connected to the opposite sides of the rotation axis of multiple rotating parts 20 by ropes, so that the vertical movement of the vertical swing power generation mechanism 3 and the horizontal movement of the oscillation power generation mechanism 4 can be converted into each other.
[0057] In an application of the present embodiment, the vertical effect is greater when the waves rise and fall, and the floating platform 1 will first rise and fall with the waves. Since the vertical swing power generation mechanism 3 is arranged at the bottom of the floating platform 1, the vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 have a hysteresis in the up and down movement. The vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 apply a downward pulling force to the floating platform 1 through the rope, which plays a damping role in the vertical direction; then, when the vertical swing power generation mechanism 3 rises and falls with the waves, the vertical swing power generation mechanism 3 can absorb the vertical kinetic energy of the waves and generate electricity, consuming the vertical kinetic energy in the waves; finally, the vertical movement of the vertical swing power generation mechanism 3 is converted into the horizontal movement of the oscillation power generation mechanism 4 through the rotating part 20, realizing the conversion of movement, further consuming the vertical kinetic energy in the waves, and reducing the vertical swing of the floating platform 1.
[0058] In another application of the present embodiment, the horizontal effect is greater when the waves rise and fall, and the floating platform 1 will first rise and fall horizontally with the waves. Since the oscillating power generation mechanism 4 is arranged at the bottom of the floating platform 1, the up and down rise and fall of the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 have a hysteresis. The vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 apply a lateral tension to the floating platform 1 through the rope, which plays a damping role in the horizontal direction; then, when the oscillating power generation mechanism 4 swings horizontally with the waves, the oscillating power generation mechanism 4 can absorb the horizontal kinetic energy of the waves and generate electricity, consuming the horizontal kinetic energy in the waves; finally, the horizontal swing of the oscillating power generation mechanism 4 is converted into the vertical movement of the vertical swing power generation mechanism 3 through the rotating part 20, realizing the conversion of motion, further consuming the horizontal kinetic energy in the waves, and reducing the horizontal swing of the floating platform 1.
[0059] It can be seen from the working process of the above application that the vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 in this embodiment use the hysteresis of motion to form motion damping; and because the vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 themselves can absorb the vertical kinetic energy and horizontal kinetic energy in the waves respectively, consume wave energy to generate electricity; and because the vertical-horizontal motion of the vertical swing power generation mechanism 3 and the oscillation power generation mechanism 4 can be converted into each other according to the conditions of the waves, therefore, through the coordinated cooperation of motion damping, power generation consumption and motion conversion, the overall motion response of the floating platform 1 is reduced, the horizontal and vertical effects of the floating platform 1 with wind and waves are effectively reduced, the anti-rolling effect is achieved, and the problem of poor anti-rolling effect of the existing power generation platform is effectively solved.
[0060] Compared with the prior art, the present embodiment has the following advantages: first, the power generation effect is good. In the present embodiment, a multi-module power generation mechanism is provided, including a vertical swing power generation mechanism 3 and an oscillating power generation mechanism 4. The vertical swing power generation mechanism 3 generates electricity through vertical swing motion, and the oscillating power generation mechanism 4 generates electricity through oscillating motion. The multi-modules generate electricity in coordination, and the power generation effect is good. Second, the anti-roll effect is good. In the present embodiment, the coordination of the three effects of motion damping, power generation consumption and motion conversion is achieved through the cooperation of the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4, and the anti-roll effect of the entire floating platform 1 is good. Third, the applicable marine environment range is wide. The floating platform 1 with good anti-roll effect has high stability, can adapt to various complex marine environmental conditions, and can be applied in a wide range of marine environments.
[0061] In a specific embodiment, Figures 1 to 6As shown, a feasible structure of a floating platform 1 is further provided, and the floating platform 1 includes a star-shaped inclined support platform body 10, a plurality of oscillating water column buoys 11 and a plurality of connecting beams 12; a heave-type power generation mechanism 3 is installed and fixed at the bottom of the inclined support platform body 10; a plurality of oscillating water column buoys 11 are evenly arranged on the peripheral side of the inclined support platform body 10, a plurality of oscillating water column buoys 11 are connected and fixed to the inclined support platform body 10, and connecting beams 12 are connected and fixed between adjacent oscillating water column buoys 11, and a rotating main shaft 200 of a rotating part 20 is rotatably installed between adjacent oscillating water column buoys 11. When it is specifically implemented, the wave When floating, the oscillating water column buoy 11 in the entire semi-submersible floating platform 1 will absorb waves and convert them into electricity, reducing the motion response of the floating platform 1 and ensuring the stable operation of the floating platform 1; at the same time, the oscillating water column wave energy power generation device is integrated and installed inside the buoy, effectively utilizing the basic space of the tension leg platform and improving the power generation space utilization rate of the platform; and utilizing the compact structure and stable layout of the semi-submersible platform as the installation carrier of the rotating main shaft 200, providing a structural basis for the connection between the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4, significantly reducing the difficulty of platform construction, deployment and maintenance.
[0062] Among them, the number of legs of the oscillating water column float 11 and the inclined support platform 10 are four. The four oscillating water column floats 11 are connected to the middle inclined support platform 10 to form a rectangular arrangement. However, the remaining number, such as three, five or more, forms other regular shapes, which can also be selected by technical personnel in this field.
[0063] In one embodiment, if Fig. 9 As shown, an achievable structure of an oscillating water column buoy 11 is further provided. Both ends of the oscillating water column buoy 11 are penetrated, and an air turbine 110 and an oscillating water column power generation assembly 111 are provided at the top of the oscillating water column buoy 11. The air turbine 110 is transmission-connected to the oscillating water column power generation assembly 111. In specific implementation, when waves float, the waves will enter the interior of the oscillating water column buoy 11 from the penetrated bottom of the oscillating water column buoy 11. After entering, the waves will push the air inside the oscillating water column buoy 11 to flow toward the air turbine 110, driving the air turbine 110 to rotate, thereby driving the rotor inside the oscillating water column power generation assembly 111 to rotate and generate electricity.
[0064] In one embodiment, if Figure 1 and Figure 2As shown, in order to improve the stability of the floating platform 1, a wind power generation component 5 is installed and fixed on the top of the inclined support platform 10 of the floating platform 1, and a mooring mechanism 6 is installed and fixed on the bottom of the floating platform 1; the mooring mechanism 6 includes a mooring chain cable 60 and a mooring base 61; the mooring base 61 is located on the projection surface of the floating platform 1 on the seabed, and the mooring base 61 is connected and fixed to the oscillating water column buoy 11 of the floating platform 1 through the mooring chain cable 60, and the mooring chain cable 60 is kept taut. In specific implementation, on the one hand, the wind power generation component 5 on the top of the floating platform 1 can generate wind power, and at the same time, it can improve the stability of the floating platform 1 as a top pressure block; on the other hand, the taut mooring chain cable 60 can The entire mooring mechanism 6 can form a tension leg structure, which can also improve the stability of the floating platform 1. The tension leg platform is light and simple in design. Compared with other floating platforms, it is lighter, which not only reduces the cost of construction materials, but also reduces the corresponding transportation and assembly costs. In addition, the mooring system designed based on the tension leg platform effectively reduces the mooring length compared to the traditional catenary mooring system of the semi-submersible platform. Under the arrangement environment of the same corresponding water depth, the mooring area is greatly reduced, the platform development space is reduced, and the space utilization rate of the sea area is improved. In addition, through the reasonable anti-roll design of the platform, the mooring load is effectively reduced, the fatigue damage of the mooring system is reduced, and the maintenance cost of the mooring system is reduced.
[0065] In this embodiment, if Figure 3 As shown, the wind power generation assembly 5 includes a wind turbine tower 50, wind turbine blades 51 and a wind turbine nacelle 52. The wind turbine blades 51 are fixedly mounted on the wind turbine nacelle 52, and the wind turbine nacelle 52 is fixed to the upper end of the wind turbine tower 50. Under the action of wind, the wind turbine blades 51 rotate in a circle around the wind turbine nacelle 52 and drive the generator set inside the wind turbine nacelle 52 to generate electricity.
[0066] In a specific embodiment, Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a feasible arrangement method of the rotating flap mechanism 2 is further provided, wherein a plurality of rotating flap mechanisms 2 are evenly arranged around the circumference of the floating platform 1, a plurality of first ropes 22 connected to the heave-type power generation mechanism 3 are evenly arranged around the circumference of the heave-type power generation mechanism 3, and a plurality of second ropes 23 connected to the oscillation-type power generation mechanism 4 are evenly arranged around the circumference of the oscillation-type power generation mechanism 4. In specific implementation, ropes are evenly connected to the circumferences of the heave-type power generation mechanism 3 and the oscillation-type power generation mechanism 4. When the heave-type power generation mechanism 3 and the oscillation-type power generation mechanism 4 are subjected to wave disturbance, uniform and stable constraints can be provided on the circumferences of the power generation mechanisms, and transmitted to the plurality of rotating flap mechanisms 2 evenly arranged on the floating platform 1, thereby providing uniform and stable damping force on the circumference of the floating platform 1.
[0067] For example, each of the four sides of the vertical swing type power generation mechanism 3 is connected with a first rope 22, and the four first ropes 22 are evenly arranged on a circumference centered on the vertical swing type power generation mechanism 3. Each first rope 22 is respectively connected to the nearest rotating flap mechanism 2, and the four rotating flap mechanisms 2 are evenly arranged on a circumference centered on the vertical swing type power generation mechanism 3, that is, with the vertical swing type power generation mechanism 3 as the center, in the four radial directions of east, south, west and north, the vertical swing type power generation mechanism 3, the first rope 22 and the rotating flap mechanism 2 in any direction are in the same straight line direction, so that the force on the vertical swing type power generation mechanism 3 is uniform. The same is true for the oscillating power generation mechanism 4, which will not be elaborated here.
[0068] In some other embodiments, each side of the vertical swing power generation mechanism 3 can be connected to multiple first ropes 22 arranged at a preset interval, and the multiple first ropes 22 on the same side are connected to the adjacent rotating flap mechanism 2. Of course, other regular connection methods can also be selected by technical personnel in this field.
[0069] In one embodiment, if Figure 4 As shown, a feasible structure of the rotating flap mechanism 2 is further provided, the rotating part 20 includes a rotating main shaft 200 and a rotating wing 201, the rotating main shaft 200 is rotatably installed between adjacent oscillating water column buoys 11, the rotating wing 201 is fixedly installed in the middle of the rotating main shaft 200 through a wing plate 24, two wing plates 24 for protecting and restraining the rotating wing 201 are arranged on opposite sides of the rotating wing 201, the rotating wing 201 is a triangular block, the maximum angle of the triangular block is connected to the rotating main shaft 200, the connecting line of the remaining two corners of the rotating wing 201 is skewed and perpendicular to the axis of the rotating main shaft 200, and the remaining two corners of the rotating wing 201 are used to respectively connect the vertical swing type power generation mechanism 3 and the oscillating type power generation mechanism 4 through the first rope 22 and the second rope 23; in specific implementation, the force generated by the movement of the vertical swing type power generation mechanism 3 and the oscillating type power generation mechanism 4 will be transmitted to the rotating wing 201 of the triangular structure, and will be decomposed along different sides and directions of the triangle, so that the force effect is more uniform, the situation of excessive local force is reduced, and the working stability is better.
[0070] Specifically, the minimum angle of the triangular block is arranged on the side away from the vertical swing power generation mechanism 3, and the middle angle of the triangular block is arranged on the side adjacent to the vertical swing power generation mechanism 3; the minimum angle of the triangular block is connected to the oscillation type power generation mechanism 4 through the second rope 23, and the middle angle of the triangular block is connected to the vertical swing power generation mechanism through the first rope 22.
[0071] It should be noted that some existing technologies often fail to enable the wave energy power generation mechanism to accurately respond to changes in wave frequency, resulting in low energy conversion efficiency and a small effective range of wave energy utilization. Based on the above embodiments, in one embodiment, Fig.10As shown, in order to enable the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 to maintain a high energy conversion efficiency under different sea conditions, the rotating flap mechanism 2 also includes a hydraulic mechanism 21; the hydraulic mechanism 21 is connected to the rotating main shaft 200, and the hydraulic mechanism 21 is used to adjust the rotational damping of the rotating main shaft 200 to adjust the movement amplitude of the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4. In specific implementation, when the wave height becomes larger, the hydraulic mechanism 21 adjusts the rotational damping of the rotating main shaft 200 to keep it within the optimal damping range, so that the movement amplitude of the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 is appropriately reduced to maintain a high energy conversion efficiency; when the waves become smaller, the hydraulic mechanism 21 adjusts the rotational damping of the rotating main shaft 200 to keep it within the optimal damping range, so that the movement amplitude of the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 is increased to maintain a high energy conversion efficiency.
[0072] It can be seen that the adjustment process of the rotating flap mechanism 2 includes: connecting the generator set through the power generation main shaft, the hydraulic mechanism 21 inside the generator set can adjust the damping and stiffness of the rotating system, and by adjusting the system damping, the rotation speed of the rotating main shaft 200 can be controlled, and the movement amplitude of the rotating main shaft 200 and the rotating wing 201 can be adjusted, so that the movement of the heave body and the oscillating body tends to be stable, and the motion phase coordination is achieved; through the above-mentioned adjustment process, the rotating flap mechanism 2 is made consistent with the wave incident frequency, so that the incident wave frequency is matched with the system natural frequency. The rotating flap mechanism 2 dynamically adjusts the system damping and stiffness according to the real-time wave conditions, can accurately respond to the change of wave frequency, and can effectively transfer the kinetic energy of the wave to the power generation device, so that it can maintain a high energy conversion efficiency under different wave frequencies and amplitudes, and broaden the effective range of wave energy utilization.
[0073] In this embodiment, the hydraulic mechanism 21 includes a hydraulic shell and a hot and cold adjusting component. The hydraulic shell is sleeved on the outside of the rotating main shaft 200. Hydraulic oil is arranged in the hydraulic shell. The hot and cold adjusting component is immersed in the hydraulic oil. During specific implementation, the viscosity of the hydraulic oil is adjusted by the hot and cold adjusting component, thereby changing the damping of the rotating main shaft 200.
[0074] It should be noted that, in addition to providing hot and cold adjustment parts in the hydraulic housing, the oil inlet and outlet of the hydraulic housing are adjustable in size. By adjusting the size of the oil inlet and outlet, the fluidity of the hydraulic oil is adjusted, thereby adjusting the damping of the rotating main shaft 200.
[0075] Based on the above embodiments, in one embodiment, in order to realize automatic damping adjustment, the power generation device also includes a control mechanism; the control mechanism includes a controller and a wave sensor for detecting wave conditions, and the controller is connected with the wave sensor and the hydraulic mechanism 21 by signal; the controller is used to control the hydraulic mechanism 21 to adjust the rotational damping of the rotating main shaft 200 according to the wave conditions. In specific implementation, when the wave sensor detects wave changes, the control mechanism controls the hydraulic mechanism 21 to adjust the damping of the rotating main shaft 200, thereby adjusting the movement amplitude of the vertical swing type power generation mechanism 3 and the oscillation type power generation mechanism 4, and realizing automatic movement amplitude adjustment.
[0076] For example, when the wave sensor detects that the wave height becomes larger, the wave sensor transmits a signal to the controller, and the controller determines that the real-time value of the wave height exceeds the preset standard range; the controller sends a signal instruction to the hot and cold adjustment parts and / or the oil inlet and outlet of the hydraulic mechanism, instructing the hot and cold adjustment parts of the hydraulic mechanism to cool the hydraulic oil to increase the viscosity of the hydraulic oil, and / or instructing the oil inlet and outlet of the hydraulic mechanism to become smaller to reduce the fluidity of the hydraulic oil. At this time, the rotation of the rotating main shaft 200 in the hydraulic oil is hindered, and the vertical movement of the vertical swing type power generation mechanism 3 and the horizontal movement of the oscillation type power generation mechanism 4 are reduced to maintain a high energy conversion efficiency under safe conditions.
[0077] On the contrary, when the wave sensor detects that the wave height becomes smaller, the wave sensor transmits a signal to the controller, and the controller determines that the real-time value of the wave height is lower than the preset standard range; the controller sends a signal instruction to the hot and cold adjustment parts and / or the inlet and outlet oil ports of the hydraulic mechanism, instructing the hot and cold adjustment parts of the hydraulic mechanism to increase the temperature of the hydraulic oil to reduce the viscosity of the hydraulic oil, and / or instructing the inlet and outlet oil ports of the hydraulic mechanism to increase the fluidity of the hydraulic oil. At this time, the rotation of the rotating main shaft 200 in the hydraulic oil is less obstructed, and the vertical movement of the vertical swing type power generation mechanism 3 and the horizontal movement of the oscillation type power generation mechanism 4 are increased to maintain a higher energy conversion efficiency under low wave and small wave conditions.
[0078] The preset standard range may be the average wave height range of local waves.
[0079] In one embodiment, if Fig.10 As shown, in order to improve the power generation efficiency, the rotating flap mechanism 2 also includes a rotating flap power generation component 25. The rotating flap power generation component 25 is arranged in the hollow space of the cylinder wall of the oscillating water column float 11. The rotating flap power generation component 25 is connected to the rotating main shaft 200 by transmission. In specific implementation, under the action of the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4, the rotating wing 201 drives the rotating main shaft 200 to rotate. After the stiffness and damping are adjusted by the hydraulic mechanism 21, the rotating flap power generation component 25 is driven to generate electricity. The entire power generation structure does not need to construct an additional complex and expensive support and reaction system, further saving development costs.
[0080] In a specific embodiment, Figures 1 to 6 As shown, a feasible arrangement of a vertical swing power generation mechanism 3 and an oscillating power generation mechanism 4 is further provided, the vertical swing power generation mechanism 3 is located above the oscillating power generation mechanism 4, that is, the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 are both located on the inner side of the bottom of the floating platform 1, and the vertical swing power generation mechanism 3 is above the oscillating power generation mechanism 4. Specifically, when implemented in the ocean, the position of the vertical swing power generation mechanism 3 will be closer to the sea surface, and the vertical kinetic energy of the seawater on the sea surface is higher. The arrangement of the vertical swing power generation mechanism 3 can improve the absorption and conversion efficiency; and the position of the oscillating power generation mechanism 4 will be closer to the inside of the seawater, and the horizontal kinetic energy of the seawater inside the seawater is higher. The arrangement of the oscillating power generation mechanism 4 can improve the absorption and conversion efficiency, that is, the position arrangement of the two can further improve the absorption efficiency of seawater energy, the electric energy conversion efficiency and the anti-rolling effect of the floating platform 1.
[0081] In one embodiment, if Figure 7 As shown, a feasible structure of a vertical swing type power generation mechanism 3 is further provided, and the vertical swing type power generation mechanism 3 includes a floating shell 30, a hydraulic piston 31, a hydraulic cylinder 32 and a vertical swing generator set 33 arranged in the floating shell 30; the floating shell 30 is connected to the rotary wing 201 through the first rope 22; one end of the hydraulic piston 31 is fixedly installed on the floating platform 1, and the other end of the hydraulic piston 31 penetrates the floating shell 30 and is installed in the hydraulic cylinder 32 by transmission; the hydraulic cylinder 32 is connected to the vertical swing generator set 33, and the hydraulic transmission of the hydraulic cylinder 32 is used to drive the vertical swing generator set 33 to generate electricity. In specific implementation, the floating shell 30 will float up and down with the waves to generate vertical damping relative to the floating platform 1, and the floating of the floating shell 30 will drive the hydraulic cylinder 32 to move up and down. Since the hydraulic piston 31 is fixed on the floating platform 1, the hydraulic piston 31 moves relative to the hydraulic cylinder 32, that is, the hydraulic piston 31 performs piston motion in the hydraulic cylinder 32, and presses the liquid in the hydraulic cylinder 32 to the vertical swing generator set 33 to perform mechanical work and generate electricity.
[0082] There are many ways in which the liquid in the hydraulic cylinder 32 is pressed to the vertical swing generator set 33 to generate electricity through mechanical movement. For example, the vertical swing generator set 33 has a rotor extending outside, and the liquid in the hydraulic cylinder 32 drives the rotor to rotate. The rotor cuts the magnetic lines of force in the magnetic field generated by the stator 41, thereby generating induced electromotive force and induced current, thereby generating electrical energy.
[0083] In one embodiment, if Figure 8As shown, an achievable structure of an oscillating power generation mechanism 4 is further provided, and the oscillating power generation mechanism 4 includes an oscillating wave-absorbing shell 40, a plurality of stators 41 arranged in the oscillating wave-absorbing shell 40, at least two elastic terminals 42, and an oscillating power generation set 43; the oscillating wave-absorbing shell 40 is connected to the rotating wing 201 through a second rope 23; a plurality of stators 41 are arranged on the circumferential side of the oscillating wave-absorbing shell 40, and two elastic terminals 42 are coaxially arranged at the top and bottom of the oscillating wave-absorbing shell 40; the oscillating power generation set 43 is arranged between the plurality of stators 41 and the two elastic terminals 42, and the oscillating power generation set 43 is suspended between the two elastic terminals 42 by the magnetic force of the plurality of stators 41; the oscillating power generation set 43 includes an oscillating wave-absorbing shell 430, a rack oscillating body 431 arranged in the oscillating wave-absorbing shell 430, and an oscillating power generation set 43 with an oscillating gear shaft. The rack oscillator 431 can move vertically in the oscillation absorbing shell 430, and the rack oscillator 431 is meshed with the oscillation gear shaft. The movement of the rack oscillator 431 is used to drive the oscillation generator 432 to generate electricity. In specific implementation, the oscillation absorbing shell 40 will swing with the sea water. The oscillation absorbing shell 40 can absorb the kinetic energy of the waves in the horizontal direction when swinging. When the oscillation absorbing shell 40 swings, the oscillation generator set 43 inside it will lag in movement under the restriction of the magnetic force of the stator 41. The oscillation absorbing shell 40 and the oscillation generator set 43 move toward each other, which plays a role of horizontal damping. When the oscillation generator set 43 swings vertically, the rack oscillator 431 inside it will move up and down, and drive the oscillation gear shaft to rotate, so as to realize the power generation function of the oscillation generator 432 cutting the stator 41 and the rotor cutting the magnetic flux lines.
[0084] In this embodiment, the elastic terminal 42 is a spring, and the shell material of the oscillation absorbing shell 40 can be configured as rubber material, polyurethane material, composite material, etc.
[0085] Based on the above embodiments, the complete working principle of the structure is provided here: when facing offshore wind, the wind power generation component 5 on the floating platform 1 can generate wind power; when facing waves, first, the floating platform 1 will float and sink with the waves, and the oscillating water column buoy 11 on the floating platform 1 can absorb wave energy and convert it into electricity during the floating and sinking process, thereby weakening the force of the wave energy on the floating platform 1; then, the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 will rise and fall to generate electricity, and within the time difference between the rise and fall of the floating platform 1 and the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4, the vertical swing power generation mechanism 3 and the oscillating power generation mechanism 4 apply the floating platform 1 through the ropes. The lateral and downward pulling forces play a damping role in the vertical and horizontal directions, reducing the swaying degree of the floating platform 1. Moreover, with the change of wave kinetic energy, the vertical movement of the vertical swing type power generation mechanism 3 and the horizontal movement of the oscillation type power generation mechanism 4 can be converted into each other, further consuming the kinetic energy of the waves, which can reduce the overall motion response of the platform, effectively reduce the horizontal and vertical effects of the platform with wind and waves, and achieve the purpose of reducing the swaying of the floating platform 1; then, the movement of the vertical swing type power generation mechanism 3 and the oscillation type power generation mechanism 4 can drive the rotating main shaft 200 to rotate and drive the rotating flap power generation assembly 25 to generate electricity, thereby realizing a complete sway reduction and power generation process.
[0086] In summary, this application has at least the following benefits:
[0087] First, the tension-leg floating platform 1 serves as a common carrier of wind turbines and multi-module wave energy power generation mechanisms. Through reasonable modular integrated installation design, various power generation devices are cleverly arranged, avoiding the waste of space resources caused by decentralized layout, greatly improving the platform space utilization rate, and realizing the compact layout and coordinated operation of multiple devices within the limited marine resource space. It can adapt to various complex marine environmental conditions. In the face of severe sea conditions with high wind speeds and large surges, the anti-roll wave energy power generation system can maintain good power generation performance and provide sufficient stability for the platform, thereby increasing the sea area range for platform layout and reducing the sea area restrictions for platform development.
[0088] The second is a tension-leg floating platform 1 integrated with a multi-module anti-roll wave energy mechanism, which responds to waves through a vertical swing power generation mechanism 3 and an oscillation power generation mechanism 4. The wave energy power generation mechanism effectively reduces the horizontal and vertical effects of the platform with wind and waves by providing a counterweight balance force and movement of natural ballast, reduces the pitch angle of the upper wind turbine, reduces fatigue damage to the wind turbine, and increases the service life of the wind turbine.
[0089] Thirdly, the multi-module anti-roll wave energy mechanism has a good power generation effect. The oscillating water column buoy 11, the floating platform 1, the vertical swing power generation mechanism 3 and the rotating flap mechanism 2 can all utilize wave energy to generate electricity, fully complementing wind energy and wave energy. This energy complementary characteristic effectively smoothes the power output curve, reduces the problem of unstable power supply caused by fluctuations in a single energy source, improves friendliness to the power grid, and facilitates better access to the existing power system.
[0090] Fourthly, by adjusting the damping of the rotating main shaft 200 through the hydraulic mechanism 21, the movement amplitude of the vertical swing type power generation mechanism 3 and the oscillation type power generation mechanism 4 can accurately respond to the change of wave frequency, so that the energy conversion efficiency of the vertical swing type power generation mechanism 3 and the oscillation type power generation mechanism 4 is maintained at a high level, thereby improving the overall power generation conversion efficiency of the wave energy device.
