Description
Technical Field
[0001] The present invention relates to the technical field of wave energy capture, and particularly to a wave energy capture device. Background Art
[0002] Wave energy is one of the water energy resources manifested in the form of kinetic energy. Wave energy has a high energy density, which is 4 - 30 times that of wind energy, and wave energy exists throughout the year. The pendulum wave energy power generation device uses a pendulum plate to swing reciprocally under the action of wave force to capture wave energy, and converts the kinetic energy and potential energy of the pendulum plate into mechanical energy or hydraulic energy through a mechanical structure or hydraulic system connected to the pendulum plate, and then converts it into electrical energy. However, the existing pendulum wave energy power generation device only captures wave energy by a single pendulum plate swinging back and forth, resulting in large energy losses in wave energy capture, low energy utilization efficiency. In addition, when a single pendulum plate is pushed by a wave, due to the rigid transmission of force, there is an easy strong impact, which will greatly reduce the service life of the device. At the same time, relying solely on some inertial devices to reset the pendulum plate does not utilize the energy of the echo, which not only loses a part of the stored energy, but also affects the stability of the overall system operation.

[0041] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0042] For the convenience of understanding, please refer to Figure 1 and Figure 2The present invention provides an embodiment of a wave energy capture device, comprising: a first leg 2, an Archimedes 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 spiral center of the Archimedes spiral wave-catching plate 1, and a plurality of support plates 7 are provided at intervals on the inner side of the spiral of the Archimedes spiral wave-catching plate 1, one end of the support plate 7 is fixed to the inner side wall of the spiral of the Archimedes spiral wave-catching plate 1, and the other end of the 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, and the center of gravity of the Archimedes spiral wave-catching plate 1 is lower than the support rod 6. The bottom of the Archimedes 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, and 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, and 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 crank shaft 4-3, a turntable 4-4 and a rocker 4-5. The support rod 6 passes through the second tripod 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 edge of the outermost spiral outlet end of the Archimedean spiral wave-catching plate 1, and 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. The power generation module 5 is transmission-connected to the turntable 4-4, and the power generation module 5 is used to convert mechanical energy into electrical energy under the rotation of the turntable 4-4.
[0043] It should be noted that if Figure 1 and Figure 2As shown, in the embodiment of the present invention, the wave-catching main structure of the wave energy capturing device is an Archimedes spiral wave-catching plate 1. A oncoming wave-catching plate 8 and a returning wave-catching plate 9 are installed at the bottom of the Archimedes wave-catching plate. The oncoming wave-catching plate 8 is arranged lower than the returning wave-catching plate 9. The oncoming wave-catching plate 8 forms a first angle with the wave surface, and the returning 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, and the second angle is greater than 90 degrees and less than 180 degrees. After the oncoming wave-catching plate 8 is subjected to the thrust of the oncoming wave (i.e., the wave flows from the sea to the shore), it will drive the Archimedes spiral wave-catching plate 1 to swing rightward and upward. When the energy of the oncoming wave is exhausted, the oncoming wave-catching plate 8 disengages from the wave, and the Archimedes spiral wave-catching plate 1 rises to the highest point. Due to the effect of the center of gravity, the Archimedes spiral wave-catching plate 1 will swing downward for the return movement. After the energy of the oncoming wave is exhausted, the wave will perform a returning wave (i.e., the wave flows back from the shore to the sea) movement. When there is a returning wave, the returning wave-catching plate 9 will drive the Archimedes spiral wave-catching plate 1 to swing leftward and downward after being subjected to the returning wave thrust. When the Archimedes spiral wave-catching plate 1 swings to contact the oncoming wave-catching plate 8 with the wave, the energy of the returning wave is exhausted. The Archimedes spiral wave-catching plate 1 converts the disordered wave energy into mechanical energy of periodic swing. Subsequently, the transmission component 4 is used to convert the swinging mechanical energy into rotational mechanical energy. The transmission component 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 tripod 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 Archimedes spiral wave-catching plate 1, and the other end of the rocker 4-5 is rotatably connected to the movable connection end of the long connecting rod 4-1 and the short connecting rod 4-2. Therefore, when the Archimedes spiral wave-catching plate 1 swings back and forth, it will drive the support rod 6 to rotate and drive 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 swinging mechanical energy into rotational mechanical energy.
[0044] In one embodiment, as Figure 3 and Figure 4As shown in the figure, the incoming wave catching plate 8 is installed at the bottom of the Archimedes wave catching plate through two first coil springs 10, and the echo wave catching plate 9 is installed at the bottom of the Archimedes wave catching plate through two second coil springs 11. The tops of the incoming wave catching plate 8 and the echo wave catching plate 9 are both 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 convex part of the convex structure, and 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 catching plate. The coil spring has the property that it is easily pulled apart by an external force and not easily rolled up. Therefore, when the incoming wave catching plate 8 is pushed by the incoming wave direction, it is easily opened downward and to the right. When the incoming wave catching plate 8 is pushed by the echo wave direction, it is not easily lifted upward. When the incoming wave catching plate 8 is opened to a certain extent, due to the limitation of the coil spring on the incoming wave catching plate 8 itself, it will limit the further opening of the incoming wave catching plate 8. At this time, the thrust received by the wave will be completely converted into the thrust on the incoming wave catching plate 8, and then into the thrust on the Archimedes spiral wave catching plate 1, driving the Archimedes spiral wave catching plate 1 to swing upward and to the right together. When the energy of the incoming wave is exhausted, the Archimedes spiral wave catching plate 1 is lifted to the highest point. Subsequently, the wave will flow back, that is, from the shore to the sea. Since the coil spring connected to the incoming wave catching plate 8 is not easily compressed, all the energy of the flowing-back wave can act on the incoming wave catching plate 8 at this time, and this part of the energy can be completely converted into the leftward thrust on the Archimedes spiral wave catching plate 1, making the Archimedes spiral wave catching plate 1 return to the normal position. The Archimedes spiral wave catching plate 1 completes a whole movement cycle, that is, it first rises to the highest point and then falls to the lowest point. The working principle of the echo wave catching plate 9 is the same as that of the incoming wave catching plate 8.
[0045] In one embodiment, the number of the incoming wave catching plates 8 is at least two, and the adjacent incoming wave catching plates 8 are arranged at intervals. The number of the echo wave catching plates 9 is at least two, and the adjacent echo wave catching plates 9 are arranged at intervals. As Figure 2As shown, taking two incoming wave catching plates 8 and two returning wave catching plates 9 as examples, when incoming waves arrive, only the right incoming wave catching plate 8 contacts the incoming waves, and then pushes the Archimedes spiral wave catching plate 1 to swing right and up. The left incoming wave catching plate 8 moves down and right. When the left incoming wave catching plate 8 drops to a certain position, it will contact the waves and move right together. When the left incoming wave catching plate 8 contacts the waves, after the Archimedes spiral wave catching plate 1 swings right and up, the right incoming wave catching plate 8 will also separate from the waves. That is, when incoming waves arrive, at the same time, only 1 incoming wave catching plate 8 contacts the waves. This can ensure that when the incoming wave catching plate 8 captures the incoming wave energy, it will not be affected by the returning wave energy. Similarly, when the returning wave catching plate 9 receives the returning wave energy, it will not be affected by the incoming wave energy. When the incoming wave energy is exhausted, the Archimedes spiral wave catching plate 1 is lifted to the highest position. At this time, the left returning wave catching plate 9 contacts the waves, and the right incoming wave catching plate 8, the left incoming wave catching plate 8, and the right returning wave catching plate 9 are all suspended in the air. When returning waves arrive, it will first move left with the left returning wave catching plate 9, then the Archimedes spiral wave catching plate 1 moves left and down. Then the left returning wave catching plate 9 is suspended in the air, and the right returning wave catching plate 9 contacts the returning waves. The right returning wave catching plate 9 moves left, and the Archimedes spiral wave catching plate 1 continues to move left and down until the right incoming wave catching plate 8 contacts the waves and the returning wave energy is exhausted.
[0046] In one embodiment, since the wave energy intensity varies in different regions or even in different months in the same region, the short connecting rod 4-2 of the transmission assembly 4 can be designed as a structure with adjustable length. By changing the length of the short connecting rod 4-2, the swing amplitude of the entire Archimedes spiral wave catching plate 1 can be changed, so that the entire wave energy capturing device can adapt to the local wave energy intensity for movement, making the operation of the entire wave energy capturing device smoother and more stable. In a specific application scenario, as Figure 5 shown, the short connecting rod 4-2 includes a first adjusting rod, a second adjusting rod, and a pin. A number of through holes are sequentially arranged at intervals on the first adjusting rod and the second adjusting rod respectively. The first adjusting rod and the second adjusting rod are fixedly connected through the cooperation of the pin and the through holes. The length of the short connecting rod 4-2 is changed by the pin installation method. In another specific application scenario, 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 portion. One end of the rod portion is connected to the head, and the rod portion and the head are designed as an integral 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 portion extends outside the chute 4-2-2. The short connecting rod 4-2 is made in the way of the chute 4-2-2 plus the first piston rod 4-2-1 to adjust the length. It can change the length of the entire short connecting rod 4-2 by the first piston rod 4-2-1 sliding independently in the chute 4-2-2 according to the local wave intensity, so as to ensure the stability of the operation of the entire system. Compared with the way of adjusting the length of the short connecting rod 4-2 by the pin type, the way of adjusting the length of the short connecting rod 4-2 by the chute 4-2-2 has stronger automatic adjustment ability.
[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 tripod 5-4 and a fourth tripod 5-5. One end of the connecting shaft 5-3 is rotatably connected to the top of the third tripod 5-4 and passes through the top of the third tripod 5-4 to be fixedly connected to one 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 tripod 5-5. The flywheel 5-1 is fixedly connected to the connecting shaft 5-3. The rotor 5-2 is fixed on the side of the flywheel 5-1. The stator is sleeved and fixed on the connecting shaft 5-3 and is located on the side where the rotor 5-2 is located. The rotor 5-2 is a brass coil. When the flywheel 5-1 rotates, it cuts the magnetic induction lines of the stator to generate electricity. In order to ensure that the long connecting rod 4-1 and the short connecting rod 4-2 can smoothly pass through the dead point position during each periodic motion, the rotational mechanical energy is stored on the flywheel 5-1, and the inertia of the rotation of the flywheel 5-1 is used to drive the long connecting rod 4-1 and the short connecting rod 4-2 to pass through the dead point position. In addition, the flywheel 5-1 rotates with inertia. Once rotated, its rotational speed almost remains unchanged, thereby ensuring that after each capture of wave energy, the Archimedes spiral wave capture board 1 can drive the flywheel 5-1 to complete a stable and smooth rotational motion through the long connecting rod 4-1 and the short connecting rod 4-2, and the rotational motion reaches a uniform speed. Thus, the disordered wave energy is converted into uniform rotational mechanical energy.
[0048] The wave energy capture device provided by the present invention has the main wave capture structure set as an Archimedes spiral wave capture plate 1. A oncoming wave capture plate 8 and a returning wave capture plate 9 are installed at the bottom of the Archimedes wave capture plate. When seawater comes from the sea towards the shore as an oncoming wave, the oncoming wave capture plate 8 is subjected to the thrust of the wave and is converted into the thrust for driving the Archimedes spiral wave capture plate 1 to swing upwards. When the energy of the oncoming wave is exhausted, the Archimedes spiral wave capture plate 1 is lifted to the highest point. After the thrust of the oncoming wave is no longer received, due to the action of the center of gravity, the Archimedes spiral wave capture plate 1 will swing downwards to return to its original position. When the wave returns from the shore to the sea, the returning wave capture plate 9 is subjected to the thrust of the wave and is converted into the thrust for driving the Archimedes spiral wave capture plate 1 to swing downwards. The Archimedes spiral wave capture plate 1 is connected to a transmission assembly 4. The transmission assembly 4 converts the mechanical energy of the swing of the Archimedes spiral wave capture plate 1 into rotational mechanical energy, and then the power generation module converts the rotational mechanical energy into electrical energy, realizing the conversion of disordered wave energy into periodic mechanical energy for power generation. Moreover, it can capture wave energy for both oncoming waves and returning waves, with less energy loss, improving the utilization efficiency of wave energy, extending the service life of the wave capture device, and also improving the stability of the operation of the wave energy capture system, solving the technical problems of the existing pendulum type wave energy power generation device that only captures wave energy by a single pendulum plate swinging back and forth, with large energy loss in wave energy capture, low energy utilization efficiency, low service life, and easy to cause unstable operation of the wave energy capture system.
[0049] In one embodiment, as Figure 1 、 Figure 7 、 Figure 8 and Figure 9As shown in the figure, the wave energy capture device provided in the present invention further includes a pressurization module, and the pressurization module includes a linkage assembly, a pressurization 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 train 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 tripod 5-5 extends outside the fourth tripod 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 in transmission. The diameter of the driving wheel 12 is larger than that of the driven wheel 14. The planetary gear train 15 is arranged inside 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 train 15. One end of the crank 17 is sleeved and fixed to 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. The other end of the connecting rod 18 is rotatably connected to the slider 19. The mechanical energy of the rotation of the flywheel 5-1, that is, the mechanical energy of the rotation of the driving wheel 12, through the transmission of the belt 13, further increases the rotational mechanical energy of the driving wheel 12 to the driven wheel 14 at the other end of the belt 13. A tensioning wheel 20 can also be arranged between the driving wheel 12 and the driven wheel 14 for cooperative transmission to increase the transmission stability. The diameter of the driving wheel 12 is several times (set to 5 times in the present invention) that of the driven wheel 14, and the rotational mechanical energy is increased by several times. The planetary gear includes 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 arranged on the planetary carrier 15-1 and are located inside the driven wheel 14. The sun gear 15-3 is located inside the three planetary gears 15-2 and is meshed and installed with each other. A gear ring 31 is arranged inside the driven wheel 14. The three planetary gears 15-2 are respectively meshed with the gear ring 31, and the three planetary gears 15-2 are all meshed with the sun gear 15-3. In the planetary gear train 15, the planetary carrier 15-1 is fixed. The belt 13 drives the driven wheel 14 to rotate, and the rotation of the driven wheel 14 drives the gear ring 31 to rotate synchronously. After the gear ring 31 rotates, it drives the sun gear 15-3 in the middle to rotate synchronously through the planetary gear 15-2. Because the number of teeth of the sun gear 15-3 is less than that of the gear ring 31, the rotation of the gear ring 31 will cause the sun gear 15-3 to rotate at an increased speed, and the speed increase ratio is the ratio of the number of teeth of the gear ring 31 to the number of teeth of the sun gear 15-3. If the number of teeth of the gear ring 31 is 4 times that of the sun gear 15-3, the mechanical energy of the rotation of the driven wheel 14 is transmitted to the sun gear 15-3 and then increased by 4 times. Then, after one wave energy capture is completed, the rotation speed of the sun gear 15-3 is 20 times that of the flywheel 5-1. The pressurization assembly includes a piston cylinder 21, a second piston rod 22, and a limit frame 23. The head of the second piston rod 22 is located inside the piston cylinder 21. One end of the rod part of the second piston rod 22 is connected to the head, and the other end is fixedly connected to the slider 19. A limit chute 24 is arranged on the limit frame 23, and the slider 19 is arranged in the limit chute 24.The torque of the sun gear 15-3 is output through the torque output shaft 16. The torque output shaft 16 drives the crank 17 and the connecting rod 18 to move, thereby driving the slider 19 to slide within the limit chute 24, converting the rotational mechanical energy into the linear reciprocating mechanical energy. The linear reciprocating motion of the slider 19 drives the second piston rod 22 to perform a linear reciprocating motion. The water inlet assembly includes a raw water tank 25, a pumping pipeline 26, and a first one-way valve 27. One end of the pumping pipeline 26 communicates with the raw water tank 25, and the other end of the pumping pipeline 26 communicates with the interior of the piston cylinder 21. The first one-way valve 27 is provided on the pumping pipeline 26, and the first one-way valve 27 is used to control the water flow direction of the pumping pipeline 26 to only flow from the raw water tank 25 to the piston cylinder 21. The water outlet assembly includes a pressurizing pipeline 29 and a second one-way valve 30. One end of the pressurizing pipeline 29 communicates with the interior of the piston cylinder 21, and the other end of the pressurizing pipeline 29 is used to convey the pressurized water flow to the target point. The second one-way valve 30 is provided on the pressurizing pipeline 29, and the second one-way valve 30 is used to control the water flow direction of the pressurizing pipeline 29 to only flow from the piston cylinder 21 to the target point. When the second piston rod 22 moves outwards, the water in the raw water tank 25 can be pumped into the piston cylinder 21. When the second piston rod 22 moves inwards, the raw water in the piston cylinder 21 is pressed out of the piston cylinder 21 and flows out as a high-pressure jet, achieving the pressurizing effect.
[0050] In one embodiment, as Figure 1 and Figure 7 shown, to avoid the difficulty in pumping water caused by insufficient suction force provided by the piston cylinder 21 and the second piston rod 22, a water pump 28 can be used to assist in pumping water. Therefore, in the present invention, the pressurizing module further 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 communicates with the water inlet end of the pumping pipeline 26.

The support frame includes support feet 32 and a support platform 33. The support platform 33 is fixed to the top of the support feet 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 set in a manner adapted to the external shape of the piston cylinder 21 to facilitate fixing the piston cylinder 21. For example, the piston cylinder 21 has a cylindrical structure, and the top of the support platform 33 is set as an arc-shaped structure.
