[0003] The working principle of a linear generator is that when the internal permanent magnet moves linearly, the magnetic flux direction of the surrounding armature winding coils reverses, thus inducing a current. Based on the working principle of linear generators and combined with the vertical movement characteristics of wave energy, wave energy generation devices based on linear generators have become an important research and development direction in the field of wave energy generation in recent years. For example, invention patent CN114744846A discloses a trapezoidal permanent magnet linear wave energy generator with adjustable transverse air gap, invention patent CN109088529A proposes a multi-faceted cylindrical permanent magnet linear wave energy generator, and invention patent CN112761851A proposes a maximum power capture control method for a direct-drive wave energy generation device.

[0004] However, the aforementioned equipment and methods still have considerable room for improvement in terms of wave energy harvesting and conversion efficiency, as well as the overall system's ability to withstand typhoons. Summary of the Invention

Both the support frame and the linear generator are fixed on a single-axis turntable. A fixed pulley for threading the rope is fixed on the cantilever of the support frame. The linear generator includes a permanent magnet mover and an electromagnetic coil stator that cooperate with each other. One end of the rope passes through the fixed pulley and is fixedly connected to the permanent magnet mover. The other end of the rope passes through a movable pulley and is fixedly connected to the end of the cantilever of the support frame. A first linear motion drive mechanism capable of driving a connecting rod to rise and fall is installed on the movable pulley. A float is fixedly connected to the lower end of the connecting rod. A second linear motion drive mechanism capable of driving the permanent magnet mover to rise and fall is installed on the single-axis turntable.

[0007] Preferably, a wave meter is installed on the float.

[0008] Preferably, the fixed pulley includes a first fixed pulley and a second fixed pulley arranged at intervals along the length of the cantilever of the support.

[0009] Preferably, the float includes a hollow shell, a partition, a suction pump, and a drain pump. The hollow shell has a partition that divides its interior into an upper chamber and a lower chamber. The suction pump and the drain pump are installed on the partition. The inlet pipe of the suction pump leads to the bottom outside of the hollow shell, and the outlet pipe of the suction pump leads to the lower chamber. The inlet pipe of the drain pump leads to the bottom of the lower chamber, and the outlet pipe of the drain pump leads to the bottom outside of the hollow shell.

[0010] Preferably, the first linear motion drive mechanism includes a first housing, a first gear, a second gear, a first motor, and a second motor. The first housing contains a first gear and a second gear that are symmetrically distributed from left to right. The upper part of the connecting rod is a double-sided rack. One side of the rack meshes with the first gear, and the other side meshes with the second gear. The first gear and the second gear are driven synchronously by the first motor and the second motor, respectively.

[0011] Preferably, the linear generator further includes a generator frame, the electromagnetic coil stator is fixed on the generator frame, and the generator frame is fixed on a single-axis turntable.

[0012] Preferably, the second linear motion drive mechanism includes a third motor, a vertical screw, a support plate, a fourth motor, and clamping clamps. Multiple third motors are evenly fixed on a single-axis turntable. The output end of each third motor is fixedly connected to the lower end of the vertical screw. The support plate is provided with a vertical nut that cooperates with the vertical screw. Two clamping clamps capable of clamping the permanent magnet mover are symmetrically installed on the support plate. The clamping clamps are fixed to corresponding horizontal nuts. The horizontal nuts cooperate with corresponding horizontal screws. One end of each horizontal screw is fixedly connected to the output end of a corresponding fourth motor. Two fourth motors are fixed to the support plate.

[0013] Meanwhile, the present invention also provides a control method for a typhoon-resistant, high-efficiency wave energy direct-drive power generation device, comprising the following steps: S1, Set the active power high operating range; S2. Collect real-time sea condition wave height and wave period data using a wave meter to determine the buoy mass corresponding to the optimal wave energy conversion efficiency. S3. Determine if the actual wave height exceeds the active wave height operating range; if it does, enter the typhoon avoidance mode. The first linear motion drive mechanism drives the float to rise through the connecting rod, the second linear motion drive mechanism drives the permanent magnet mover to descend, the permanent magnet mover drives the movable pulley to rise through the rope, and the movable pulley drives the float to rise further through the first linear motion drive mechanism and the connecting rod, thereby making the float away from the sea surface. Then, the single-axis turntable rotates 180° to make the float completely leave the sea surface; if it does not exceed the range, proceed to step S4. S4. Adjust the float mass within the range corresponding to the optimal wave energy conversion efficiency: If the float mass needs to be increased, the suction pump will work and the drainage pump will not work, and the float mass will be increased; if the float mass needs to be decreased, the drainage pump will work and the suction pump will not work, and the float mass will be decreased; if the float mass needs to be maintained at its current state, proceed to step S5. S5. Measure the buoy acceleration in real time using the accelerometer inside the wave meter to determine whether the average amplitude of the buoy has reached its peak value. If it has not reached the peak value, repeat step S4. If it has reached the peak value, neither the suction pump nor the drainage pump will work, and the buoy mass will remain fixed.

[0014] Compared with existing technologies, this invention has the following advantages: The float drives the rope tensioning motion via a connecting rod, a first linear motion drive mechanism, and a movable pulley.

The float drives the permanent magnet mover of the linear generator via the movable pulley and cable. The speed of the permanent magnet mover is twice that of the float, thus achieving the function of speed increase and further improving the efficiency of wave energy collection and conversion.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. 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. To make the above features and advantages of this invention more apparent and understandable, specific embodiments are provided below with reference to the accompanying drawings for detailed description.

[0024] like Figures 1 to 6As shown, an embodiment of the present invention provides a typhoon-resistant, high-efficiency wave energy direct-drive power generation device, including a support 9, a linear generator 10, and a rope 13. The support 9 and the linear generator 10 are both fixed on a single-axis turntable 12. A fixed pulley for threading the rope 13 is fixed on the cantilever of the support 9. The linear generator 10 includes a permanent magnet mover 1001 and an electromagnetic coil stator 1002 that cooperate with each other. One end of the rope 13 passes through the fixed pulley and is fixedly connected to the permanent magnet mover 1001. The other end of the rope 13 passes through a movable pulley 5 and is fixedly connected to the end of the cantilever of the support 9. A first linear motion drive mechanism 4 capable of driving the connecting rod 3 to rise and fall is installed on the movable pulley 5. A float 1 is fixedly connected to the lower end of the connecting rod 3. A second linear motion drive mechanism 11 capable of driving the permanent magnet mover 1001 to rise and fall is installed on the single-axis turntable 12. The cantilever end of the support 9 is provided with a rope fixing point 6, which facilitates the binding of the other end of the rope 13; the fixed pulley may include, but is not limited to, a first fixed pulley 7 and a second fixed pulley 8 arranged at intervals along the length of the cantilever of the support 9.

[0025] The working principle of this embodiment is as follows: the float 1 moves up and down under the action of waves. The float 1 drives the rope 13 to move through the connecting rod 3, the first linear motion drive mechanism 4 and the movable pulley 5. The rope 13 drives the permanent magnet mover 1001 to move up and down in a linear motion. The magnet mover 1001 cuts the electromagnetic coil stator 1002 to generate electricity. The float 1 drives the permanent magnet mover 1001 of the linear generator 10 to move through the movable pulley 5 and the cable 13. The speed of the permanent magnet mover 1001 is twice the speed of the float 1, thereby realizing the speed increase function and further improving the efficiency of wave energy collection and conversion. During typhoon season, the first linear motion drive mechanism 4 drives the connecting rod 3 to rise, and the connecting rod 3 drives the float 1 to rise and leave the sea surface; the second linear motion drive mechanism 11 drives the permanent magnet mover 1001 to descend, and the permanent magnet mover 1001 drives the pulley 5 to rise through the rope 13, thereby causing the float 1 to rise further and leave the sea surface; the single-axis turntable 12 rotates, and the bracket 9 drives the float 1 to rotate until the float 1 is completely above the sea surface.

[0026] In this embodiment, in order to adjust the mass of the float 1, the float 1 includes a hollow shell 101, a partition 102, a water suction pump 103, and a water discharge pump 104. The hollow shell 101 is fixed with a partition 102 that divides its internal cavity into an upper chamber and a lower chamber. The water suction pump 103 and the water discharge pump 104 are mounted on the partition 102. The inlet pipe of the water suction pump 103 leads to the bottom of the hollow shell 101, and the outlet pipe of the water suction pump 103 leads to the lower chamber. The suction pump 103 draws seawater into the hollow outer shell 101, while the inlet pipe of the drain pump 104 leads to the bottom of the lower chamber, and the outlet pipe leads to the outside of the bottom of the hollow outer shell 101. The drain pump 104 discharges seawater out of the float shell 101. The function of the suction pump 103 and the drain pump 104 is to change the mass of the float 1 according to the wave conditions, thereby aligning the natural frequency of the float 1 with the wave frequency and improving the power generation efficiency of the device. To facilitate the collection of real-time sea state wave height and wave period data, a wave meter 2 is installed on the float 1, specifically fixed to the outside of the hollow outer shell 101.

[0027] In this embodiment, to ensure smooth lifting and lowering of the connecting rod 3, the first linear motion drive mechanism 4 includes a first housing 401, a first gear 402, a second gear 403, a first motor, and a second motor. The first housing 401 houses the first gear 402 and the second gear 403, which are symmetrically distributed. The upper part of the connecting rod 3 is a double-sided rack. One side of the rack meshes with the first gear 402, and the other side meshes with the second gear 403. The first gear 402 and the second gear 403 are synchronously driven by the first motor and the second motor, respectively. This synchronous drive of the rack by the two gears ensures smooth lifting and lowering of the connecting rod 3 and extends its service life. The function of the first linear motion drive mechanism 4 is to adjust the distance between the float 1 and the movable pulley 5. In typhoon weather, the first linear motion drive mechanism 44 drives the connecting rod 3 upward, causing the float 1 to move away from the sea surface.

[0028] In this embodiment, the linear generator 10 further includes a generator frame 1003, the electromagnetic coil stator 1002 is fixed on the generator frame 1003, and the generator frame 1003 is fixed on a single-axis turntable 12. The function of the single-axis turntable 12 is to rotate the float 1 180° completely above the sea surface after it has been propelled away from the sea surface by the first linear motion drive mechanism 4 and the second linear motion drive mechanism 11 during typhoon weather. The second linear motion drive mechanism 11 is located below the generator frame 1003.

[0029] In this embodiment, the second linear motion drive mechanism 11 includes a third motor 1101, a vertical screw 1102, a support plate 1103, a fourth motor 1104, and a clamping clamp 1105. Multiple (e.g., four) of the third motors 1101 are evenly fixed on the single-axis turntable 12. The output end of the third motor 1101 is fixedly connected to the lower end of the vertical screw 1102. The support plate 1103 is provided with a vertical nut that cooperates with the vertical screw 1102. Two clamping clamps 1105 capable of clamping the permanent magnet mover 1001 are symmetrically installed on the support plate 1103. The clamping clamps 1105 are fixed on the corresponding horizontal nuts. The horizontal nuts cooperate with the corresponding horizontal screws. One end of the horizontal screw is fixedly connected to the output end of the corresponding fourth motor 1104. The two fourth motors 1104 are fixed on the support plate 1103. The function of the second linear motion drive mechanism 11 is to drive the two clamping clamps 1105 to move towards each other and clamp the permanent magnet mover 1001 when encountering typhoon weather through two sets of fourth motors 1104, horizontal screws and horizontal nuts. Then, the support plate 1103 and the clamping clamps 1105 on it are driven to descend through the third motor 1101, vertical screws 1102 and vertical nuts, thereby pulling the permanent magnet mover 1001 to the bottom and making the float 1 further away from the sea surface.

[0030] This embodiment also provides a control method for a typhoon-resistant, high-efficiency wave energy direct-drive power generation device, including the following steps: S1, Set the active power high operating range; S2. Collect real sea condition wave height and wave period data using wave meter 2 to determine the mass of float 1 corresponding to the optimal wave energy conversion efficiency; S3. Determine if the actual wave height exceeds the active wave height operating range; if it does, enter the typhoon avoidance mode. The first linear motion drive mechanism 4 drives the float 1 to rise through the connecting rod 3, and the second linear motion drive mechanism 11 drives the permanent magnet mover 1001 to fall. The permanent magnet mover 1001 drives the movable pulley 5 to rise through the rope 13. The movable pulley 5 drives the float 1 to rise further through the first linear motion drive mechanism 4 and the connecting rod 3, thereby making the float 1 move away from the sea surface. Then, the single-axis turntable 12 rotates 180°, making the float 1 completely leave the sea surface; if it does not exceed the range, proceed to step S4. S4. Adjust the mass of float 1 within the range corresponding to the optimal wave energy conversion efficiency: If the mass of float 1 needs to be increased, the suction pump 103 will work and the drainage pump 104 will not work, and the mass of float 1 will increase; if the mass of float 1 needs to be decreased, the drainage pump 104 will work and the suction pump 103 will not work, and the mass of float 1 will decrease; if the mass of float 1 needs to be maintained at its current state, then proceed to step S5. S5. Measure the acceleration of float 1 in real time using the accelerometer in wave meter 2 to determine whether the average amplitude of float 1 has reached the peak value. If it has not reached the peak value, repeat step S4. If it has reached the peak value, neither the suction pump 103 nor the drainage pump 104 will work, and the mass of float 1 will be fixed.

[0031] This embodiment improves the structural reliability of wave energy conversion to electrical energy, the stability of system operation, and the overall system's resistance to wind and waves. Regarding improving wave energy harvesting and conversion efficiency, the weight of the buoy can be adjusted according to wave conditions, thereby adjusting the buoy's added mass and natural frequency, enabling the buoy to achieve high wave energy capture efficiency over a wider incident wave frequency range. Simultaneously, the buoy drives the permanent magnet mover of the linear generator via a movable pulley, cable, and fixed pulley. The speed of the permanent magnet mover is twice the speed of the buoy, thus achieving an acceleration function and further improving wave energy harvesting and conversion efficiency. In terms of the system's typhoon resistance, a typhoon avoidance mode is included to shelter from typhoons and improve the device's survivability.
