Description
Technical Field
[0001] The present invention relates to the technical field of wave energy capture, and in particular to a wave energy capture device. Background Art
[0002] Wave energy is a type of hydropower resource expressed in the form of kinetic energy. Wave energy has a high energy density, 4-30 times that of wind energy, and is available year-round. Pendulum wave power generation devices utilize a pendulum plate to swing back and forth under the influence of wave forces to capture wave energy. A mechanical structure or hydraulic system connected to the pendulum plate converts the plate's kinetic and potential energy into mechanical or hydraulic energy, and then into electrical energy. However, existing pendulum wave power generation devices capture wave energy solely through the back-and-forth swinging of a single pendulum plate, resulting in significant energy losses and low energy efficiency. Furthermore, when a single pendulum plate is pushed by waves, the rigid transmission of force makes it susceptible to strong impacts, significantly shortening the device's service life. Furthermore, relying solely on inertial devices to reset the pendulum plate fails to utilize the return wave energy, resulting in a loss of stored energy and impacting the overall system's operational stability.

[0041] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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 making creative efforts shall fall within the scope of protection of the present invention.
[0042] For easier understanding, see Figure 1 and Figure 2The present invention provides an embodiment of a wave energy capture device, comprising: a first leg 2, an Archimedean spiral wave-catching plate 1, a second leg 3, a transmission assembly 4, and a power generation module 5. A support rod 6 is provided through the center of the spiral of the Archimedean spiral wave-catching plate 1. Several support plates 7 are spaced apart inside the spiral of the Archimedean spiral wave-catching plate 1. One end of each support plate 7 is fixed to the inner wall of the spiral of the Archimedean spiral wave-catching plate 1, and the other end of each support plate 7 is fixed to the support rod 6. One end of the support rod 6 is rotatably connected to the top of the first leg 2, and the other end of the support rod 6 is rotatably connected to the top of the second leg 3. The center of gravity of the Archimedean spiral wave-catching plate 1 is lower than the support rod 6. The bottom of the Archimedean wave-catching plate is equipped with an incoming wave-catching plate 8 and an echo wave-catching plate 9. The incoming wave-catching plate 8 is arranged lower than the echo wave-catching plate 9. The incoming wave-catching plate 8 forms a first angle with the wave surface, while the echo wave-catching plate 9 forms a second angle with the wave surface. The first angle is greater than 0 degrees and less than 90 degrees, while the second angle is greater than 90 degrees and less than 180 degrees. The transmission assembly 4 includes a long connecting rod 4-1, a short connecting rod 4-2, a crankshaft 4-3, a turntable 4-4, and a rocker 4-5. The support rod 6 passes through the second leg 3 and is rotatably connected to one end of the long connecting rod 4-1. The other end of the long connecting rod 4-1 is rotatably connected to one end of the short connecting rod 4-2. The other end of the short connecting rod 4-2 is rotatably connected to one end of the crankshaft 4-3. The other end of the crankshaft 4-3 is fixedly connected to a surface of the turntable 4-4. One end of the rocker 4-5 is fixedly connected to the side of the outermost spiral outlet end of the Archimedean spiral wave-catching plate 1. The other end of the rocker 4-5 is rotatably connected to the movable connection ends of the long connecting rod 4-1 and the short connecting rod 4-2. A power generation module 5 is drivingly connected to the turntable 4-4 and is configured to convert mechanical energy into electrical energy as the turntable 4-4 rotates.
[0043] It should be noted that if Figure 1 and Figure 2As shown, the wave energy capture device provided in an embodiment of the present invention comprises an Archimedean spiral wave-catching plate 1. An incoming wave-catching plate 8 and an echo wave-catching plate 9 are mounted at the bottom of the Archimedean spiral wave-catching plate. The incoming wave-catching plate 8 is positioned lower than the echo wave-catching plate 9. The incoming wave-catching plate 8 forms a first angle with the wave surface, while the echo wave-catching plate 9 forms a second angle with the wave surface. The first angle is greater than 0 degrees and less than 90 degrees, while the second angle is greater than 90 degrees and less than 180 degrees. Upon receiving thrust from incoming waves (i.e., waves flowing from the sea to the shore), the incoming wave-catching plate 8 swings rightward and upward, carrying the Archimedean spiral wave-catching plate 1 with it. When the incoming wave energy is depleted, the incoming wave-catching plate 8 detaches from the waves, and the Archimedean spiral wave-catching plate 1 rises to its highest point. Due to the center of gravity, the Archimedean spiral wave-catching plate 1 swings downward to return to its original position. When the incoming wave's energy is depleted, it begins an echo motion (i.e., the wave flows back out to sea from the shore). During this echo, the echo catcher plate 9, under the thrust of the echo, swings the Archimedean spiral catcher plate 1 downward and leftward. When the Archimedean spiral catcher plate 1 swings until it contacts the incoming wave catcher plate 8, the echo's wave energy is depleted. The Archimedean spiral catcher plate 1 converts the chaotic wave energy into periodic oscillatory mechanical energy. This oscillatory mechanical energy is then converted into rotational mechanical energy by the transmission assembly 4. The transmission assembly 4 comprises a long connecting rod 4-1, a short connecting rod 4-2, a crankshaft 4-3, a turntable 4-4, and a rocker 4-5. The support rod 6 passes through the second leg 3 and is rotatably connected to one end of the long connecting rod 4-1. The other end of the long connecting rod 4-1 is rotatably connected to one end of the short connecting rod 4-2. The other end of the short connecting rod 4-2 is rotatably connected to one end of the crankshaft 4-3. The other end of the crankshaft 4-3 is fixedly connected to one side of the turntable 4-4. One end of the rocker 4-5 is fixedly connected to the side of the outermost spiral outlet end of the Archimedean spiral wave-catching plate 1. The other end of the rocker 4-5 is rotatably connected to the movable connection ends of the long connecting rod 4-1 and the short connecting rod 4-2. Therefore, when the Archimedean spiral wave-catching plate 1 swings back and forth, it drives the support rod 6 to rotate and drives the rocker 4-5 to swing. The rocker 4-5 drives the long connecting rod 4-1 and the short connecting rod 4-2 to swing, thereby driving the crankshaft 4-3 to drive the turntable 4-4 to rotate, converting the mechanical energy of the swinging into mechanical energy of rotation.
[0044] In one embodiment, Figure 3 and Figure 4As shown, the incoming wave capture plate 8 is mounted on the bottom of the Archimedes wave capture plate via two first coil springs 10, and the echo wave capture plate 9 is mounted on the bottom of the Archimedes wave capture plate via two second coil springs 11. The tops of both the incoming wave capture plate 8 and the echo wave capture plate 9 are convex structures. The inner ends of the first coil spring 10 and the second coil spring 11 are fixedly connected to one side of the raised portion of the convex structure, while the outer ends of the first coil spring 10 and the second coil spring 11 are fixedly connected to the bottom of the Archimedes wave capture plate. Coil springs are easily pulled apart by external forces but not easily rolled up. Therefore, when the incoming wave capture plate 8 is pushed in the direction of the incoming wave, it is easily opened downward and rightward. However, when the incoming wave capture plate 8 is pushed in the direction of the echo wave, it is not easily lifted upward. When the incoming wave catcher 8 opens to a certain extent, the coil spring itself restricts the incoming wave catcher 8 from further opening. At this time, the thrust of the waves will be completely converted into thrust on the incoming wave catcher 8, and then into thrust on the Archimedes spiral catcher 1, driving the Archimedes spiral catcher 1 to swing right and upward. When the energy of the incoming wave is exhausted, the Archimedes spiral catcher 1 is lifted to its highest point, and then the wave will flow back from the shore to the sea. Because the coil spring connected to the incoming wave catcher 8 is not easily compressed, the backflow of wave energy at this time will fully act on the incoming wave catcher 8, and this part of energy can be completely converted into thrust on the Archimedes spiral catcher 1 to the left, causing the Archimedes spiral catcher 1 to return to the right. The Archimedes spiral catcher 1 completes an entire movement cycle, first lifting to the highest point and then falling back to the lowest point. The working principle of the return wave catcher 9 is the same as that of the incoming wave catcher 8.
[0045] In one embodiment, the number of the incoming wave capture plates 8 is at least two, and adjacent incoming wave capture plates 8 are spaced apart, and the number of the echo wave capture plates 9 is at least two, and adjacent echo wave capture plates 9 are spaced apart. Figure 2As shown, taking two incoming wave catching plates 8 and two echo wave catching plates 9 as an example, when a wave approaches, only the right-side incoming wave catching plate 8 contacts the incoming wave, which then pushes the Archimedean spiral wave catching plate 1 to swing rightward and upward, while the left-side incoming wave catching plate 8 moves downward and rightward. When the left-side incoming wave catching plate 8 drops to a certain position, it contacts the wave and moves rightward together. When the left-side incoming wave catching plate 8 contacts the wave, the right-side incoming wave catching plate 8 will also break away from the wave after the Archimedean spiral wave catching plate 1 swings rightward and upward. That is, when a wave approaches, only one incoming wave catching plate 8 contacts the wave at a time. This ensures that the incoming wave catching plate 8 will not be affected by the return wave energy when capturing the incoming wave energy. Similarly, the echo wave catching plate 9 will not be affected by the incoming wave energy when receiving the return wave energy. When the incoming wave energy is depleted, the Archimedean spiral wave-catching plate 1 is raised to its highest point. At this point, the left echo-catching plate 9 contacts the wave, and the right incoming wave-catching plate 8, the left incoming wave-catching plate 8, and the right echo-catching plate 9 are all suspended in mid-air. When the wave returns, the left echo-catching plate 9 is first moved to the left, followed by the Archimedean spiral wave-catching plate 1 moving leftward and downward. The left echo-catching plate 9 is then suspended in mid-air, while the right echo-catching plate 9 contacts the returning wave. The right echo-catching plate 9 moves leftward, and the Archimedean spiral wave-catching plate 1 continues to move leftward and downward until the right incoming wave-catching plate 8 contacts the wave, and the returning wave energy is depleted.
[0046] In one embodiment, since the wave energy intensity varies from region to region, or the wave energy intensity varies from month to month in the same region, the short connecting rod 4-2 of the transmission assembly 4 can be designed as a length-adjustable structure. By changing the length of the short connecting rod 4-2, the swing amplitude of the entire Archimedean spiral wave-catching plate 1 can be changed, and finally the entire wave energy capture device can adapt to the local wave energy intensity to move, making the operation of the entire wave energy capture device more stable and smooth. In a specific application scenario, such as Figure 5 As shown, the short connecting rod 4-2 includes a first adjusting rod, a second adjusting rod and a latch. The first adjusting rod and the second adjusting rod are respectively provided with a plurality of through holes spaced apart in sequence. The first adjusting rod and the second adjusting rod are fixedly connected by the latch and the through holes. The length of the short connecting rod 4-2 can be changed by installing the latch. In another specific application scenario, such as Figure 6As shown, the short connecting rod 4-2 includes a first piston rod 4-2-1 and a chute 4-2-2. The first piston rod 4-2-1 includes a head and a rod. One end of the rod is connected to the head. The rod and the head are designed as an integrated structure. The head of the first piston rod 4-2-1 is located inside the chute 4-2-2, and the other end of the rod extends outside the chute 4-2-2. The short connecting rod 4-2 is configured as a chute 4-2-2 plus a first piston rod 4-2-1 to adjust its length. The first piston rod 4-2-1 can slide autonomously within the chute 4-2-2 to change the length of the entire short connecting rod 4-2 in accordance with the local wave intensity, thereby ensuring the stability of the entire system. Compared with the pin-type method of adjusting the length of the short connecting rod 4-2, the chute 4-2-2 method of adjusting the length of the short connecting rod 4-2 has a stronger automatic adjustment capability.
[0047] In one embodiment, the power generation module 5 includes a flywheel 5-1, a stator, a rotor 5-2, a connecting shaft 5-3, a third leg 5-4, and a fourth leg 5-5. One end of the connecting shaft 5-3 is rotatably connected to the top of the third leg 5-4 and passes through the top of the third leg 5-4 to be fixedly connected to the side of the turntable 4-4 facing away from the crankshaft 4-3. The other end of the connecting shaft 5-3 passes through the center of the flywheel 5-1 and is rotatably connected to the top of the fourth leg 5-5. The flywheel 5-1 is fixedly connected to the connecting shaft 5-3, the rotor 5-2 is fixed to the side of the flywheel 5-1, and the stator is fixedly mounted on the connecting shaft 5-3 and located on the side where the rotor 5-2 is located. The rotor 5-2 is a brass coil that cuts the stator's magnetic flux lines to generate electricity when the flywheel 5-1 rotates. To ensure that both the long connecting rod 4-1 and the short connecting rod 4-2 pass through their dead points smoothly during each cyclical motion, the rotational mechanical energy is stored in the flywheel 5-1. The flywheel 5-1's rotational inertia drives both the long connecting rod 4-1 and the short connecting rod 4-2 through their dead points. Furthermore, the flywheel 5-1 exhibits rotational inertia, maintaining a nearly constant rotational speed once it has rotated. This ensures that after each wave energy capture, the Archimedean spiral wave-catching plate 1, through both the long connecting rod 4-1 and the short connecting rod 4-2, can drive the flywheel 5-1 through stable and smooth rotation, achieving a uniform rotational speed. Thus, the chaotic wave energy is converted into uniformly rotating mechanical energy.
[0048] The wave energy capture device provided by the present invention sets the main structure of wave capture as an Archimedes spiral wave capture plate 1, and the bottom of the Archimedes wave capture plate is installed with an incoming wave capture plate 8 and an echo wave capture plate 9. When the sea water comes from the sea to the shore, the thrust of the incoming wave capture plate 8 is converted into a thrust for driving the Archimedes spiral wave capture plate 1 to swing upward. When the energy of the incoming wave is exhausted, the Archimedes spiral wave capture plate 1 is lifted to the highest point. When there is no thrust from the incoming wave, the Archimedes spiral wave capture plate 1 will swing back to its position due to the effect of the center of gravity. When the wave echoes from the shore to the sea, the thrust of the echo wave capture plate 9 is converted into a thrust for driving the Archimedes spiral wave capture plate 1 to swing downward. The Archimedes spiral wave capture plate 1 and the transmission wave capture plate 1 are connected. The driving component 4 is connected, and the transmission component 4 converts the mechanical energy of the swing of the Archimedean spiral wave-catching plate 1 into rotational mechanical energy, and then the power generation module converts the rotational mechanical energy into electrical energy, thereby realizing the conversion of disordered wave energy into periodic mechanical energy for power generation, and can capture wave energy for both incoming waves and echoes, with less energy loss, improved wave energy utilization efficiency, extended service life of the wave-catching device, and improved operation stability of the wave energy capture system, solving the technical problems of the existing pendulum wave energy power generation device that only captures wave energy by swinging back and forth through a single pendulum plate, resulting in large energy loss in wave energy capture, low energy utilization efficiency, short service life, and easy instability of the wave energy capture system.
[0049] In one embodiment, Figure 1 、 Figure 7 、 Figure 8 and Figure 9As shown, the wave energy capture device provided in the present invention also includes a boosting module, which includes a linkage assembly, a boosting assembly, a water inlet assembly, and a water outlet assembly. The linkage assembly includes a driving wheel 12, a belt 13, a driven wheel 14, a planetary gear system 15, a torque output shaft 16, a crank 17, a connecting rod 18, and a slider 19. One end of the connecting shaft 5-3 of the power generation module 5 connected to the fourth leg 5-5 extends outward from the fourth leg 5-5 and is fixedly connected to one side of the driving wheel 12. The driving wheel 12 and the driven wheel 14 are connected by a belt 13. The diameter of the driving wheel 12 is larger than that of the driven wheel 14. The planetary gear system 15 is arranged on the inner side of the driven wheel 14. One end of the torque output shaft 16 is fixedly connected to the sun gear 15-3 of the planetary gear system 15. One end of the crank 17 is fixedly mounted on the other end of the torque output shaft 16. The other end of the crank 17 is rotatably connected to one end of the connecting rod 18, and the other end of the connecting rod 18 is rotatably connected to the slider 19. The mechanical energy generated by the rotation of flywheel 5-1, also known as the mechanical energy generated by the rotation of driving wheel 12, is further accelerated by belt 13, transferring the rotational mechanical energy of driving wheel 12 to driven wheel 14 at the other end of belt 13. A tensioning pulley 20 may also be provided between driving wheel 12 and driven wheel 14 for coordinated transmission and increased transmission stability. If the diameter of driving wheel 12 is several times the diameter of driven wheel 14 (set to five times in the present invention), the rotational mechanical energy is increased several times. The planetary gears include a planetary carrier 15-1, three planetary gears 15-2, and one sun gear 15-3. The three planetary gears 15-2 and one sun gear 15-3 are all mounted on planetary carrier 15-1 and located inside driven wheel 14. Sun gear 15-3 is located inside the three planetary gears 15-2 and meshes with each other. A ring gear 31 is located inside the driven gear 14. Three planetary gears 15-2 mesh with each other, and all three planetary gears 15-2 mesh with the sun gear 15-3. In the planetary gear train 15, the planet carrier 15-1 is stationary. The belt 13 rotates the driven gear 14, which in turn rotates the ring gear 31 in sync. The ring gear 31 rotates, which in turn rotates the center sun gear 15-3 via the planetary gears 15-2. Because sun gear 15-3 has fewer teeth than ring gear 31, the rotation of ring gear 31 accelerates the rotation of sun gear 15-3 by a ratio equal to the number of teeth on ring gear 31 to the number of teeth on sun gear 15-3. If the number of teeth on the ring gear 31 is four times that of the sun gear 15-3, the mechanical energy from the rotation of the driven wheel 14 is transferred to the sun gear 15-3 and then accelerated by another four times. Therefore, after a wave energy capture cycle, the rotation speed of the sun gear 15-3 is 20 times that of the flywheel 5-1. The booster assembly includes a piston cylinder 21, a second piston rod 22, and a limiting frame 23. The head of the second piston rod 22 is located within the piston cylinder 21. One end of the rod portion of the second piston rod 22 is connected to the head portion, and the other end is fixedly connected to the slider 19. The limiting frame 23 is provided with a limiting slot 24, and the slider 19 is disposed within the limiting slot 24.The torque of sun gear 15-3 is output through torque output shaft 16, which drives crank 17 and connecting rod 18, thereby driving slider 19 to slide within limiting chute 24, converting rotational mechanical energy into linear reciprocating mechanical energy. The linear reciprocating motion of slider 19 drives the second piston rod 22 to move linearly. The water inlet assembly includes a raw water tank 25, a pumping pipe 26, and a first one-way valve 27. One end of pumping pipe 26 is connected to the raw water tank 25, and the other end of pumping pipe 26 is connected to the interior of piston cylinder 21. First one-way valve 27 is installed on pumping pipe 26 and is used to control the direction of water flow in pumping pipe 26 so that it can only flow from the raw water tank 25 to the piston cylinder 21. The water outlet assembly includes a pressurizing pipe 29 and a second one-way valve 30. One end of the pressurizing pipe 29 communicates with the interior of the piston cylinder 21, while the other end is used to deliver the pressurized water to the target location. The second one-way valve 30 is mounted on the pressurizing pipe 29 to control the flow of water in the pressurizing pipe 29, restricting it to flow from the piston cylinder 21 to the target location. When the second piston rod 22 moves outward, it pumps water from the raw water tank 25 into the piston cylinder 21. When the second piston rod 22 moves inward, the raw water in the piston cylinder 21 is forced out of the cylinder 21, becoming a high-pressure jet and achieving a pressurized effect.
[0050] In one embodiment, Figure 1 and Figure 7 As shown, to avoid pumping difficulties caused by insufficient pumping force provided by the piston cylinder 21 and the second piston rod 22, a water pump 28 can be used to assist in pumping. Therefore, in the present invention, the booster module also includes a water pump 28. The water pump 28 is disposed within the raw water tank 25, and the water outlet of the water pump 28 is connected to the water inlet of the pumping pipe 26.
[0051] In one embodiment, Figure 1 and Figure 7 As shown, in the present invention, the booster module also includes a support frame, which includes support legs 32 and a support platform 33. The support platform 33 is fixed to the top of the support legs 32, and the top of the support platform 33 is used to place the piston cylinder 21. The top of the support platform 33 can be configured to adapt to the external shape of the piston cylinder 21 to facilitate the fixing of the piston cylinder 21. For example, if the piston cylinder 21 has a cylindrical structure, the top of the support platform 33 can be configured as an arc-shaped structure.
