[0002] The ocean possesses abundant clean and renewable energy resources, including wind, wave, tidal, thermal gradient, and ocean current energy. Among these, wind energy is characterized by its abundant resources, high utilization hours, lack of land occupation, and suitability for large-scale development. Wave energy, on the other hand, boasts advantages such as high energy density, wide distribution, sustainable utilization, and lack of temporal and spatial limitations. Wind and wave energy hold the greatest potential for large-scale development and utilization. Given the similarities in geographical distribution between wave and wind energy, the scientific integration of offshore wind turbines and wave energy generation devices can reduce construction costs and improve the utilization rate of offshore renewable energy.

[0076] This invention provides a wave energy-wind energy combined power generation device and control method to solve the technical problem that existing offshore power generation devices have asynchronous and mismatched wind and wave resources, which leads to low efficiency in the synchronous utilization of wind and wave resources.

[0077] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0078] Please see Figure 1 , Figure 1 This is a schematic diagram of a wave energy-wind energy combined power generation device provided in an embodiment of the present invention.

[0079] This invention provides a wave energy-wind energy combined power generation device, comprising a floating platform 2, a wind turbine generator 1, and a wave energy mechanism 4; the floating platform 2 is equipped with a tilt angle detection mechanism, which is used to acquire the platform tilt angle data of the floating platform 2 and compare it with preset standard tilt angle data to generate a comparison result; the wind turbine generator 1 is installed on the upper end of the floating platform 2, and is used to adjust its orientation position to acquire wind energy in response to the received comparison result; the wave energy mechanism 4 is movably connected to the floating platform 2, and is used to adjust its wave-facing angle to acquire wave energy in response to the received comparison result.

[0080] It should be noted that the wind turbine generator 1 and the wave energy mechanism 4 are installed on the floating platform 2. The floating platform 2 is equipped with a tilt angle detection mechanism, which is a tilt angle sensor. The tilt angle data of the floating platform 2 is acquired in real time through the tilt angle detection mechanism. When the platform tilt angle data is less than the preset standard tilt angle data, the orientation position of the wind turbine generator 1 installed on the upper part of the floating platform is adjusted to obtain wind energy. The wind load acts on the blades 8, driving the wind turbine generator rotor in the nacelle 7 to rotate, which can convert wind energy into the mechanical energy of the wind turbine generator rotor. The rotation of the wind turbine generator rotor drives the generator to generate electricity, thus converting mechanical energy into electrical energy, realizing the conversion of wind energy into mechanical energy and then generating electricity. At the same time, the wave-facing angle of the wave energy mechanism 4, which is movably connected to the floating platform 2, is adjusted. To capture wave energy, under the action of wave load, the wave-absorbing float 26 moves upward, driving the hydraulic rod 22 to compress the hydraulic oil and spring in the hydraulic cylinder 21, converting wave energy into hydraulic energy and spring mechanical energy. When the wave-absorbing float 26 moves upward to a certain extent, the wave load is insufficient to continue doing work on the wave-absorbing float 26, and the spring pushes the wave-absorbing float 26 back to its initial position. The reciprocating motion of the wave-absorbing float 26 converts wave energy into hydraulic energy and spring mechanical energy, which is then used to generate electricity through a generator. This process converts wave energy into electrical energy, and part of the converted electrical energy can be stored in an external energy storage device. At the same time, the converted electrical energy provides working power for various electrical devices in the wave-wind combined power generation device, while the other part is transmitted to the power grid through a transmission system for use by land users.

[0081] In the specific implementation, the wind turbine generator 1 is installed above the floating platform 2, and the wave energy mechanism 4 is set inside the floating platform 2. When the tilt angle detection mechanism detects that the tilt angle of the floating platform is greater than the preset value, the wave energy mechanism 4 is driven by the rotating support installed inside the floating platform 2 to achieve wave countermeasure. At the same time, the blades 8 installed on the hub 6 are controlled by starting the nacelle 7 inside the wind turbine generator 1 to achieve wind countermeasure.

[0082] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a wind turbine generator set 1 of a wave energy-wind energy combined power generation device provided in an embodiment of the present invention.

[0083] The present invention provides a wave energy-wind energy combined power generation device, wherein the wind turbine generator 1 includes a tower 5, a hub 6, a nacelle 7 and blades 8; the bottom of the tower 5 is fixedly connected to a floating platform 2; the nacelle 7 is installed on the top of the tower 5; the blades 8 are connected to the nacelle 7 through the hub 6; a yaw system is installed in the nacelle 7, which is used to acquire wind direction deviation data and control the orientation position of the blades 8;

[0084] It should be noted that the wind turbine generator set 1 includes a tower 5, a hub 6, a nacelle 7, and blades 8. The nacelle 7 is equipped with a yaw system. When the direction of the wind speed vector changes, the blades 8 are controlled to quickly and smoothly align with the wind direction, thereby maximizing the capture of wind energy.

[0085] It is worth mentioning that the wind direction deviation data refers to the adjustment data generated by comparing the target wind speed and target wind direction angle with the associated standard wind speed and standard wind direction angle. When the target wind speed is greater than the standard wind speed (that is, when the wind speed exceeds the maximum allowable operating wind speed), the wind turbine generator 1 yaws and stops operating. When the target wind speed is less than the standard wind speed (that is, when the wind speed is less than the maximum allowable operating wind speed) and the target wind direction angle (the target wind direction angle refers to the angle between the optimal wind direction angle of the wind turbine generator 1 and the actual wind direction angle) is greater than the standard wind direction angle (that is, the maximum allowable wind direction angle), the yaw system of the wind turbine generator 1 is activated, yaws against the wind, and captures wind energy to the maximum extent.

[0086] It is worth mentioning that yaw braking, also known as yaw braking, refers to adjusting the wind turbine rotor's windward position through the yaw system when the yaw angle of the wind turbine generator set 1 exceeds the safe range, thereby reducing the yaw angle of the wind turbine generator set 1 to ensure its safe operation and high stability. In other words, it locks in under extreme operating conditions to ensure the safety of the wind turbine generator set 1.

[0087] Yaw-to-wind refers to using a yaw system to make the wind turbine face the wind directly when the wind speed is within the limit, so as to maximize the conversion of wind energy into mechanical energy and then generate electricity.

[0088] The present invention provides a wave energy-wind energy combined power generation device, wherein the yaw system includes a first drive motor, a wind speed and direction detection mechanism, and a first controller; the wind speed and direction detection mechanism is electrically connected to the first controller and is used to acquire wind direction and wind speed data; the first controller is connected to the first drive motor; the first controller is used to receive wind direction and wind speed data and perform comparison operations to generate wind direction deviation data; the first drive motor is drivenly connected to the blade 8 and is used to drive the blade 8 to rotate according to the received wind direction deviation data.

[0089] It should be noted that the wind speed and direction detection mechanism is electrically connected to the first controller. The wind speed and direction detection mechanism acquires wind direction and wind speed data and transmits the wind direction and wind speed data to the first controller for comparison and operation, thereby generating wind direction deviation data. The first controller is connected to the first drive motor, and the first controller drives the blade 8 to rotate to align with the wind, thereby maximizing the acquisition of wind energy.

[0090] It is worth mentioning that the wind speed and direction detection mechanism is electrically connected to the first controller. The wind speed and direction detection mechanism obtains wind direction and speed data and transmits the wind direction and speed data to the first controller for comparison. Based on the generated wind direction deviation data, the controller sends a clockwise or counterclockwise yaw command to the drive motor, which drives the blade 8 to yaw against the wind. Once the yaw is completed, the first drive motor stops working, and the yaw process ends.

[0091] It is worth mentioning that the wind speed and direction detection mechanism is an anemometer. The wind speed measurement part of the anemometer uses microcomputer technology and can simultaneously measure instantaneous wind speed, instantaneous wind level, average wind speed, average wind level, and corresponding wave height. It has a data latching function for easy reading. The wind direction part uses an automatic north-pointing device, eliminating the need for manual north alignment during measurement and simplifying the measurement operation. The wind speed and direction detection mechanism can also be composed of an anemometer and a wind direction sensor. The sensing element of the anemometer is a three-cup wind assembly, consisting of three carbon fiber cups and a cup holder. The converter is a multi-tooth rotating cup and a slit optocoupler. When the cups rotate under the action of horizontal wind force, the rotation of the rotating cups in the slit optocoupler outputs a frequency signal. The converter of the wind direction sensor is a code disk and a photoelectric component. When the anemometer rotates with the wind direction, the shaft drives the code disk to rotate in the gap of the photoelectric component. The generated photoelectric signal corresponds to the Gray code output of the wind direction at that time. The sensor's converter can use a precision conductive plastic potentiometer, thereby generating a changing voltage signal output at the potentiometer's moving end. The first controller can be a combinational logic controller, CPU controller, LED controller, or microprogram controller, and has data processing capabilities. The comparison operation refers to comparing the acquired wind speed and wind direction angle data with the preset maximum allowable operating wind speed and maximum allowable wind direction angle. The wind direction angle data refers to the angle between the optimal wind direction angle of wind turbine generator 1 and the actual wind direction angle, ultimately generating wind direction deviation data. If the wind direction deviation data indicates that the wind speed exceeds the maximum allowable operating wind speed, wind turbine generator 1 yaws and stops operating. If the wind direction deviation data indicates that the wind speed is less than the maximum allowable operating wind speed and the angle between the optimal wind direction angle and the actual wind direction angle of wind turbine generator 1 is greater than the maximum allowable angle, the yaw system of wind turbine generator 1 is activated. The first controller drives the blades 8 to rotate and yaw towards the wind, maximizing wind energy capture. Specifically, the first controller controls the first drive motor, and the output shaft of the first drive motor drives the hub 6 to rotate, which in turn drives the blades 8 mounted on the hub 6 to rotate, thereby achieving wind alignment.

Each of the two circular mounting frames 11 contains a fixing rod 13. The shape of the fixing rod 13 is determined by the shape of the platform's main frame. For example, if the platform's main frame is pentagonal, then the fixing rod 13 consists of five support rods, dividing the inner side of the circular mounting frame 11 into five equal sectors. Notably, one end of each of the five support rods is connected to the other end, which is connected to the inner side of the circular mounting frame 11. The outer edge of the circular mounting frame 11 is connected to the middle of the connecting rod 10 within the platform's main frame.

[0109] This invention provides a wave energy-wind energy combined power generation device. The wave energy mechanism 4 includes a first hinge plate 19, a second hinge plate 20, two hydraulic cylinders 21, two hydraulic rods 22, two first connecting rods 23, two second connecting rods 24, two third connecting rods 25, and a wave-absorbing float 26. One side of the first hinge plate 19 is fixedly connected to a support plate rib 16. Two hydraulic cylinders 21 are hinged to the other side of the first hinge plate 19, and the two hydraulic cylinders 21 are arranged in parallel and spaced apart. The other end of each hydraulic cylinder 21 away from the first hinge plate 19 is differentially connected to one end of a hydraulic rod 22, and the hydraulic cylinders 21 and hydraulic rods 22 are used in cooperation. The other end of each hydraulic rod 22 is connected to the first... One side of the connecting rod 23 is hinged near the middle; one end of each of the two first connecting rods 23 is hinged to one side of the second hinge plate 20, and the two first connecting rods 23 are arranged in parallel and spaced apart; the other side of the second hinge plate 20 is fixedly connected to the support plate rib 16; the other end of each of the two first connecting rods 23 is hinged to the wave-absorbing float 26; one end of each of the two second connecting rods 24 is hinged to the other side of the first connecting rod 23 near the middle; the other end of each of the two second connecting rods 24 is connected to one end of the third connecting rod 25 through a spring, and the two second connecting rods 24 are arranged in parallel and spaced apart; the other end of each of the two third connecting rods 25 is connected to the wave-absorbing float 26, and the two third connecting rods 25 are arranged in parallel and spaced apart.

[0110] It should be noted that the first hinge plate 19 and the second hinge plate 20 are arranged parallel to each other vertically and are fixed to the rotating inner support by welding. The two hydraulic cylinders 21, two hydraulic rods 22, two first connecting rods 23, two second connecting rods 24, and two third connecting rods 25 are all arranged parallel to each other. One side of the first hinge plate 19 is fixedly connected to the support plate rib 16; two hydraulic cylinders 21 are hinged to the other side of the first hinge plate 19, and the two hydraulic cylinders 21 are arranged parallel to each other. The other end of each hydraulic cylinder 21, away from the first hinge plate 19, is differentially connected to one end of a hydraulic rod 22. The hydraulic cylinders 21 and hydraulic rods 22 cooperate, and the other end of the hydraulic rods 22 cooperates with the hydraulic cylinders 21 to form a friction pair; the other ends of the two hydraulic rods 22 are also... The first connecting rod 23 is hinged to one side of the rod body near the middle; one end of each of the two first connecting rods 23 is hinged to one side of the second hinge plate 20, and the two first connecting rods 23 are arranged in parallel and spaced apart; the other side of the second hinge plate 20 is fixedly connected to the support plate rib 16; the other end of each of the two first connecting rods 23 is hinged to the wave-absorbing float 26; one end of each of the two second connecting rods 24 is hinged to the other side of the rod body of the first connecting rod 23 near the middle; the other end of each of the two second connecting rods 24 is connected to one end of the third connecting rod 25 through a spring, and the two second connecting rods 24 are arranged in parallel and spaced apart; the other end of each of the two third connecting rods 25 is connected to the wave-absorbing float 26. It is worth mentioning that the other end of each of the two third connecting rods 25 can be hinged or fixedly connected to the wave-absorbing float 26, and the two third connecting rods 25 are arranged in parallel and spaced apart. Under the action of wave load, the wave-absorbing float 26 moves upward, driving the hydraulic rod 22 to compress the hydraulic oil in the hydraulic cylinder 21 and the spring, converting wave energy into hydraulic energy and spring mechanical energy. When the wave-absorbing float 26 moves upward to a certain extent, the wave load is insufficient to continue to do work on the wave-absorbing float 26, and the spring pushes the wave-absorbing float 26 back to the initial position, starting the next wave energy capture-conversion cycle.

[0111] In the specific implementation, under the action of wave load, the wave-absorbing float 26 moves upward, driving the hydraulic rod 22 installed on the first connecting rod 23 to compress the hydraulic oil in the hydraulic cylinder 21, converting wave energy into hydraulic energy. At the same time, by driving the third connecting rod 25 and the second connecting rod 24 installed on the first connecting rod 23 to compress the spring, the wave energy is converted into mechanical energy.

[0112] The working process of a wave energy-wind energy combined power generation device:

[0113] When wind speed and wave height are both within the operating range, with the wind turbine blade 8 facing the wind and the wave energy mechanism 4 facing the wave as the initial state, the system maximizes the capture of wind and wave energy, achieving efficient conversion of wind and wave energy resources into electrical energy. When the direction of the wind speed vector changes, the yaw system on the wind turbine 1 adjusts the direction of the wind turbine to quickly and smoothly align it with the wind direction, maximizing the capture of wind energy. When the direction of the incoming wave changes by more than a certain angle θ (this angle can be set), the steering system controls the steering system to adjust the angle between the wave-facing surface of the support and the incoming wave, so that the wave-absorbing float 26 is aligned with the incoming wave. The wave energy mechanism 4 is designed to efficiently capture wave energy. Waves are random, and their direction changes frequently. To avoid reduced structural fatigue life or insufficient returns due to frequent adjustments in the direction of the wave energy mechanism 4, factors such as structural reliability and returns must be considered. It is recommended that θ be set to 30°, at which point the incoming wave energy is 75% of that when facing the wave head-on. The control system allows the wind turbine generator 1 and the wave energy mechanism 4 to be relatively independent and adjust their orientations independently, enabling the wind turbine generator 1, the wave energy mechanism 4, and the wind and wave resources to move in sync, thus achieving efficient capture of wind and wave energy resources.

[0114] When wind speed or wave height exceeds the operating range, the wind turbine generator 1 and wave energy mechanism 4 are shut down accordingly. When a destructive typhoon strikes and the wind speed exceeds the operating range of the wind turbine generator 1, the wind turbine blades 8 stop rotating under the control system, yaw and lock facing the typhoon, and the blades 8 pitch, minimizing the wind-facing area to reduce stress. In extreme sea conditions where wave height exceeds the operating range of the wave energy mechanism 4, the wave energy mechanism 4 folds close to the rotating support 3 under the control system, and the rotating support 3 is adjusted to be parallel to the direction of the incoming wave and locked in place, minimizing the wave-facing area to reduce wave load. By adjusting the spatial orientation of the wind turbine generator 1 and wave energy mechanism 4, the wind-facing and wave-facing areas are minimized, reducing wind-wave load and improving the safety and reliability of the device.

[0115] Please see Figure 6-8 When the stability of the device is insufficient under extreme sea conditions (the maximum allowable tilt angle of the platform is generally 15°), the stability of the device can be improved by adjusting the position of the wave energy device to change the center of gravity of the structure and increasing the restoring torque.

[0116] Please see Figure 9-12 , Figure 9 A flowchart illustrating the steps of a control method for a wave-wind combined power generation device provided in an embodiment of the present invention.

[0117] Figure 10 This is a control flowchart of a control method for a wave energy-wind energy combined power generation device provided in an embodiment of the present invention.

[0119] Figure 12 This is a schematic diagram illustrating the adjustment and change of the center of gravity of a wave energy-wind energy combined power generation device provided in an embodiment of the present invention.

[0120] This invention provides a control method for a wave energy-wind energy combined power generation device, which includes a floating platform 2, a wind turbine generator 1, and a wave energy mechanism 4. The method includes:

[0121] 101. In response to the detected platform tilt angle data of the floating platform 2, compare the platform tilt angle data with the preset standard tilt angle data;

[0122] 102. When the platform tilt angle data is less than the preset standard tilt angle data, wind energy is obtained by adjusting the orientation of wind turbine generator 1;

[0123] 103. Wave energy is obtained by adjusting the wave-facing angle of the wave energy mechanism 4.

[0124] In this embodiment of the invention, in response to the detected platform tilt angle data of the floating platform 2, the platform tilt angle data is compared with the preset standard tilt angle data; when the platform tilt angle data is less than the preset standard tilt angle data, wind energy is obtained by adjusting the orientation position of the wind turbine generator 1; wave energy is obtained by adjusting the wave-facing angle of the wave energy mechanism 4.

[0125] Please see Figure 10 , Figure 10 This is a control flowchart of a control method for a wave energy-wind energy combined power generation device provided in an embodiment of the present invention.

[0126] When the tilt angle of the device exceeds the maximum permissible tilt angle specified by the classification society, wind turbine generator 1 and wave energy mechanism 4 are shut down. When the tilt angle of the device is less than the maximum permissible tilt angle specified by the classification society, wind parameters such as wind speed and wind direction, as well as wave parameters such as wave direction, are measured. When the wind speed exceeds the maximum permissible operating wind speed, wind turbine generator 1 yaws and stops operating; when the wind speed is less than the maximum permissible operating wind speed and the angle between the optimal wind direction angle and the actual wind direction angle is greater than the maximum permissible angle, the wind turbine yaw system is activated, yaws against the wind, and captures wind energy to the maximum extent. When the wave height exceeds the maximum permissible operating wave height, wave energy mechanism 4 is locked and stops operating; when the wave height is less than the maximum wave height and the angle between the optimal angle of wave energy mechanism 4 and the actual incoming wave direction is less than the maximum permissible angle between the actual incoming wave directions, rotating support 3 is activated, rotates against the waves, and captures wave energy to the maximum extent. Figure 7 In this context, Ψ represents the angle of inclination, and Ψ0 is the maximum permissible angle of inclination specified by the classification society, typically taken as 15°.min α is the minimum tilt angle of the platform during the 360° rotation of the wave energy mechanism 4; α is the safety margin factor, generally taken as 0.9 to 0.95; υ is the wind speed, υ0 is the maximum allowable operating wind speed of the wind turbine generator 1; ω is the wind direction angle, δω is the angle between the optimal wind turbine angle and the actual wind direction angle, and δω0 is the maximum allowable angle between the optimal wind turbine angle and the actual wind direction angle; H s For wave height, H s0 θ represents the maximum permissible wave height for wave energy mechanism 4; θ represents the wave direction; δθ represents the angle between the optimal angle of wave energy mechanism 4 and the actual incoming wave direction; and δθ0 represents the maximum permissible angle between the actual incoming wave directions.

[0127] In the specific implementation, the tilt angle data of the device is detected by the tilt angle detection mechanism. When the tilt angle data is greater than or equal to the preset standard tilt angle data, the wind turbine generator set 1 yaws and stops operating. When the tilt angle data is less than the preset standard tilt angle data, wind parameters such as wind speed and wind direction are obtained. The obtained target wind speed is compared with the maximum allowable operating wind speed. If the target wind speed is greater than the maximum allowable operating wind speed, the wind turbine generator set 1 yaws and stops operating. If the target wind speed is less than or equal to the maximum allowable operating wind speed, the angle between the optimal wind turbine angle and the actual wind direction angle (equivalent to the target wind direction angle) is obtained. When the angle between the optimal wind turbine angle and the actual wind direction angle is greater than the maximum allowable angle, the blades 8 installed on the hub 6 are controlled by starting the nacelle 7 in the wind turbine generator set 1 to achieve wind alignment.

[0128] When the platform tilt angle data is greater than or equal to the preset standard tilt angle data, the wave energy mechanism 4 is rotated 360°, the minimum tilt angle of the platform is recorded, and the platform is adjusted to this position. The target multiplier between the safety margin coefficient and the preset standard tilt angle data is calculated, and the minimum tilt angle of the platform is compared with the target multiplier. If the minimum tilt angle of the platform is greater than or equal to the target multiplier, the wave energy mechanism 4 is shut down. If the minimum tilt angle of the platform is less than the target multiplier, the process jumps to the step of obtaining wave parameters such as wave direction. When the platform tilt angle data is less than the preset standard tilt angle data, wave parameters such as wave direction are obtained, and the wave height is compared with the maximum allowable operating wave height. If the wave height is greater than or equal to the maximum allowable operating wave height, the process jumps to the step of obtaining wave parameters such as wave direction. If the maximum wave height is allowed, the angle between the optimal angle of the wave energy mechanism 4 and the actual incoming wave direction is compared with the maximum allowable angle between the actual incoming wave direction. If the angle between the optimal angle of the wave energy mechanism 4 and the actual incoming wave direction is greater than or equal to the maximum allowable angle between the actual incoming wave direction, the wave energy mechanism 4 is rotated to counteract the waves by rotating the support member 3 until the angle between the optimal angle of the wave energy mechanism 4 and the actual incoming wave direction is less than the maximum allowable angle between the actual incoming wave direction. If the angle between the optimal angle of the wave energy mechanism 4 and the actual incoming wave direction is less than the maximum allowable angle between the actual incoming wave direction, the rotation is stopped by locking the automatic locking device 18.
