Technical Field

[0002] Seawater can be used for both power generation and desalination. However, existing seawater resource utilization technologies operate in isolation, with power generation and desalination devices operating as separate, independent units. This lack of coordination between the two results in isolated and inefficient seawater resource utilization. Therefore, the design of a multifunctional, integrated seawater resource utilization system is a pressing technical challenge for those skilled in the art. Summary of the Invention

DETAILED DESCRIPTION

[0070] 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.

[0071] For easier understanding, see Figure 1 The present invention provides an embodiment of a one-stop system for wave energy power generation and seawater desalination, comprising a wave energy power generation device 100, a boosting device 200, a hydraulic energy storage and discharge device 300, and a seawater desalination device 400 connected in sequence.

[0072] The wave energy power generation device 100 is used to capture wave energy, convert the wave energy into rotational mechanical energy, and generate electricity by cutting magnetic flux lines under the action of the rotational mechanical energy.

[0073] The boosting device 200 is used to boost the pressure of the seawater in the preset cavity by utilizing the rotational mechanical energy of the wave energy power generation device 100 .

[0074] The hydraulic energy storage and discharge device 300 is used to store the seawater output from the boosting device 200 and perform hydraulic energy storage.

[0075] The seawater desalination device 400 is used to receive the seawater outputted by the hydraulic energy storage and discharge device 300 when discharging energy and perform seawater desalination.

[0076] It should be noted that in this embodiment of the present invention, the wave energy power generation device 100 captures wave energy, converts it into rotational mechanical energy, and drives the electromagnetic coils within the wave energy power generation device 100 to cut through magnetic flux lines to generate electricity. A boosting device 200 is connected to the wave energy power generation device 100. The boosting device 200 utilizes the rotational mechanical energy of the wave energy power generation device 100 to boost the pressure of the seawater within a predetermined cavity. The boosted seawater is then transferred to the hydraulic energy storage and discharge device 300 for hydraulic energy storage. The hydraulic energy storage and discharge device 300 hydraulically stores and discharges the seawater. During the discharge process, the seawater within the hydraulic energy storage and discharge device 300 is transferred to the seawater desalination device 400, which desalinates the seawater.

[0077] The one-stop wave energy power generation and seawater desalination system provided by the present invention connects a wave energy power generation device 100, a boosting device 200, a hydraulic energy storage and discharge device 300 and a seawater desalination device 400 in sequence, integrating the wave energy power generation, seawater boosting, hydraulic energy storage and seawater desalination functions into the same system, realizing multifunctional one-stop utilization, improving the coordination between multiple seawater resource utilization devices, and solving the technical problem that the existing seawater resource utilization devices lack joint coordination capabilities, resulting in low seawater resource utilization efficiency.

[0078] In one embodiment, the one-stop wave energy power generation and seawater desalination system provided by the present invention further includes a surplus energy recovery device 500. The surplus energy recovery device 500 is configured to receive concentrated water output by the desalination device 400 during the desalination process and utilize the concentrated water output by the desalination device 400 to generate electricity. The desalination device 400 produces fresh water and a portion of concentrated water during desalination. Energy can be further recovered from the concentrated water, which is then output to the surplus energy recovery device 500 and used to generate electricity, maximizing the utilization of seawater energy.

[0079] In one embodiment, Figure 2As shown, the wave energy power generation device 100 includes: 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. A plurality of 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.

[0080] It should be noted that if Figure 2 and Figure 3As shown, the wave energy power generation device 100 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. When thrusted by 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 breaks away 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.

[0081] In one embodiment, Figure 4 and Figure 5As 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.

[0082] 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 3As 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.

[0083] 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 6 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 7As 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.

[0084] 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.

[0085] The wave energy power generation device 100 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 waves from the sea to the shore, the incoming wave capture plate 8 is subjected to the thrust of the waves and converted into a thrust to drive 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 original position due to the effect of the center of gravity. When the wave echoes from the shore to the sea, the echo wave capture plate 9 is subjected to the thrust of the waves and converted into a thrust to drive the Archimedes spiral wave capture plate 1 to swing downward. The Archimedes spiral wave capture plate 1 and the transmission 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 stability of the wave energy capture system operation, solving the technical problems of the existing pendulum wave energy power generation device 100 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 operation.

[0086] In one embodiment, Figure 2 、 Figure 8 、 Figure 9 and Figure 10As shown, the supercharging device 200 provided in the present invention includes a linkage assembly, a supercharging 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 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 train 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 train 15. One end of the crank 17 is sleeved and fixed 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.

[0087] In one embodiment, Figure 2 and Figure 8 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 device 200 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.

[0088] In one embodiment, Figure 2 and Figure 8 As shown, in the present invention, the booster device 200 further 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 to have an arc-shaped structure.

[0089] In one embodiment, Figure 11As shown, the hydraulic energy storage and discharge device 300 comprises a cylinder A1, a piston plate A2, a counterweight shaft A3, a counterweight assembly A4, a drive mechanism A5, a laser rangefinder A7, an energy storage valve module A8, an energy discharge valve module A9, and a controller A6. A water inlet is defined at the bottom of one side wall of cylinder A1, and a water outlet is defined at the bottom of the other side wall of cylinder A1. An energy storage valve module A8 is mounted outside the water inlet and is electrically connected to controller A6. An energy discharge valve module A9 is mounted outside the water outlet and is electrically connected to controller A6. The piston plate A2 is slidably installed inside the cylinder A1, and the driving mechanism A5 is installed on the top of the piston plate A2. The bottom of the counterweight shaft A3 is rotatably connected to the top of the piston plate A2 through the driving mechanism A5. The shaft body of the counterweight shaft A3 is fixed with a number of pressure bearing blocks A3-13-1 in a stepped manner. The several pressure bearing blocks A3-13-1 are rotated in sequence on the counterweight shaft A3 at preset angles in a circumferential array according to the height of the steps. The driving mechanism A5 is connected to the controller A6, and the driving mechanism A5 is used to drive the counterweight shaft A3 to rotate horizontally under the control of the controller A6. Counterweight assembly A4 comprises a receiving plate A-42 and a counterweight A4-1. Receiver plate A-42 is fixed parallel to piston plate A2 within cylinder barrel A1 and positioned above piston plate A2. Receiver plate A-42 is provided with through-holes for the counterweight shaft A3 and pressure bearing block A3-13-1 to pass through. Counterweight A4-1 is placed atop receiving plate A-42. Counterweight A4-1 has a through-hole of the same shape as that of pressure bearing block A3-13-1, and the through-hole on receiving plate A-42 is larger than that on counterweight A4-1. There are at least two counterweight assemblies A4, with adjacent counterweight assemblies spaced apart in height. A laser rangefinder A7 is fixedly mounted on counterweight assembly A4 and electrically connected to controller A6. Laser rangefinder A7 measures the height of piston plate A2.

[0090] It should be noted that cylinder A1 can be constructed from two halves fastened together with bolts A10 and a sealing ring. A piston plate A2 is located within cylinder A1. When the valve of energy storage valve module A8 is opened and the valve of energy release valve module A9 is closed, water can enter cylinder A1 from outside through the water inlet of cylinder A1, causing piston plate A2 to rise. Laser rangefinder A7 measures the height change of piston plate A2 and transmits this height information to controller A6. Based on the height position of piston plate A2, controller A6 calculates the energy storage capacity of cylinder A1 and determines the load-bearing capacity of counterweight shaft A3. As piston plate A2 rises, counterweight shaft A3 rises with it. The receiving block 3-1 at the top of counterweight shaft A3 passes through a through-hole in receiving plate A-42. Controller A6 determines the load capacity of counterweight shaft A3 based on the energy storage capacity of cylinder A1 and acquired wave energy data. When counterweight A4-1 needs to be added to counterweight shaft A3, drive mechanism A5 controls the rotation of counterweight shaft A3, causing the corresponding pressure receiving block A3-13-1 to lift counterweight A4-1, creating a hydraulic energy storage counterweight and increasing the hydraulic energy storage limit. When the valve of storage valve module A8 closes and the valve of discharge valve module A9 opens, the water in cylinder A1 flows out of the water outlet of cylinder A1, causing piston plate A2 to descend. Laser rangefinder A7 measures the height change of piston plate A2 and transmits this height information to controller A6. When the piston plate A2 descends, the counterweight shaft A3 descends along with the piston plate A2. When the pressure bearing block A3-13-1 on the counterweight shaft A3, which supports the counterweight block A4-1, descends to the through hole of the supporting plate A-42, the counterweight block A4-1 is supported by the supporting plate A-42, and the pressure bearing block A3-13-1 is separated from the counterweight block A4-1, thereby reducing the hydraulic energy storage limit.

[0091] It should also be noted that there are at least two counterweight assemblies A4. In the embodiment of the present invention, there is no restriction on the number of counterweight assemblies A4. In a specific practical application scenario, the number of counterweight assemblies A4 can be configured according to actual needs. The laser rangefinder A7 is installed on the counterweight assembly A4 closest to the piston plate A2 to facilitate the measurement of the height of the piston plate A2. The shaft body of the counterweight shaft A3 is fixed with a number of pressure bearing blocks A3-13-1 in a stepped manner, and the number of pressure bearing blocks A3-13-1 on the counterweight shaft A3 is not less than the number of counterweight assemblies A4. A number of pressure bearing blocks A3-13-1 are arranged in a circumferential array on the counterweight shaft A3 in sequence of stepped heights to preset angles, which is conducive to quickly, evenly and accurately controlling the rotation adjustment of the counterweight shaft A3 driven by the driving mechanism A5. In a specific embodiment, as Figures 12 to 14 As shown, the pressure bearing block A3-13-1 is a triangular structure, and the triangular structure pressure bearing block A3-13-1 is rotated in sequence by preset angles on the counterweight shaft A3 in a circumferential array arrangement according to the step height.

[0092] In the hydraulic energy storage and discharge device 300 provided by the present invention, an energy storage valve module A8 controls the water inflow of the cylinder A1, an energy discharge valve module A9 controls the water outflow of the cylinder A1, and a piston plate A2 rises and falls according to the water volume at the bottom of the cylinder A1. A laser rangefinder A7 measures the height position of the piston plate A2 and sends it to a controller A6. The controller A6 calculates the hydraulic energy storage capacity based on the received height position data of the piston plate A2, and controls the driving mechanism A5 to drive the counterweight shaft A3 to rotate horizontally according to the hydraulic energy storage capacity, thereby changing the connection relationship between the pressure receiving block A3-13-1 and the counterweight block A4-1, thereby changing the number of counterweight blocks A4-1 pressed on the counterweight shaft A3, and realizing automatic adjustment of the hydraulic energy storage mass block to adjust the energy storage limit. This solves the technical problems of the existing piston-type hydraulic energy storage system in that the mass block weight cannot be automatically adjusted according to the liquid volume in the container, the energy storage limit is fixed at the factory, the energy storage limit is single and cannot be adjusted, the degree of automation is low, and the real-time adjustability is poor.

[0093] In one embodiment, Figure 15 As shown, the drive mechanism A5 includes a forward / reverse motor A5-1, a first bevel gear A5-2, and a second bevel gear A5-3. The forward / reverse motor A5-1 is electrically connected to a controller A6. The output end of the forward / reverse motor A5-1 is fixedly connected to the first bevel gear A5-2, which meshes with the second bevel gear A5-3. The second bevel gear A5-3 is rotatably mounted on the top of the piston plate A2 and fixedly connected to the bottom of the counterweight shaft A3. Driven by the forward / reverse motor A5-1, the first bevel gear A5-2 rotates vertically, while the second bevel gear A5-3 rotates horizontally. The forward and reverse rotation of the forward / reverse motor A5-1 drives the first bevel gear A5-2 to rotate clockwise and counterclockwise. The second bevel gear A5-3 meshes with the first bevel gear A5-2. The rotation of the first bevel gear A5-2 drives the second bevel gear A5-3, thereby driving the counterweight shaft A3 forward and reverse.

[0094] In one embodiment, Figure 16As shown, the energy storage valve module A8 includes an inlet pipe A8-3, a first control motor A8-1, and an inlet valve A8-2. One end of the inlet pipe A8-3 is connected to the water inlet of the cylinder A1. The inlet valve A8-2 is installed on the inlet pipe A8-3. The inlet valve A8-2 is electrically connected to the first control motor A8-1, which is connected to the controller A6. The first control motor A8-1 is used to control the opening and closing of the inlet valve A8-2. The first control motor A8-1 is a linear motor. The output end of the first control motor A8-1 is connected to the valve handle, which is connected to the valve switch. The first control motor A8-1 controls the valve opening and closing by pushing the handle. The energy release valve module A9 has the same structure as the energy storage valve module A8. It includes an outlet pipe, a second control motor, and an outlet valve. One end of the water outlet pipe is connected to the water outlet of the cylinder A1. A water outlet valve is provided on the water outlet pipe. The water outlet valve is electrically connected to the second control motor. The second control motor is connected to the controller A6. The second control motor is used to control the opening and closing of the water outlet valve.

[0095] In one embodiment, Figure 17 As shown, the hydraulic energy storage and release adaptive control system of the present invention also includes a wind power generation assembly A11. Wind power generation assembly A11 is mounted on top of cylinder A1 and comprises a wind cup A11-1, a first power generation module A11-2, a mounting rod, and a power storage module A11-3. Wind cup A11-1 is rotatably connected to the first power generation module A11-2 and mounted on the mounting rod. The first power generation module A11-2 is electrically connected to the power storage module A11-3. The power storage module A11-3 is electrically connected to the controller A6 and the drive mechanism A5, respectively. Wind cup A11-1 captures wind energy, transmits it to the first power generation module A11-2 for power generation, and stores the energy in the power storage module A11-3. The mounting rod comprises a vertical mounting rod A11-4 and a horizontal mounting rod A11-5. The bottom of the vertical mounting rod A11-4 is mounted on the top of the cylinder A1. One end of the horizontal mounting rod A11-5 is fixed to the side wall of the vertical mounting rod A11-4. The other end of the horizontal mounting rod A11-5 is mounted with the wind cup A11-1 and the first power generation module A11-2. There are four horizontal mounting rods A11-5, which are mounted on the vertical mounting rod A11-4 in a cross shape with the vertical mounting rod A11-4 as the center. The wind cups A11-1 on the four horizontal mounting rods A11-5 can generate wind power simultaneously. Figure 7 and Figure 8As shown, wind power generation assembly A11 also includes a second power generation module A11-6. The bottom of vertical mounting rod A11-4 is mounted on the top of cylinder A1 via second power generation module A11-6. The bottom of vertical mounting rod A11-4 is rotatably connected to second power generation module A11-6, which is electrically connected to power storage module A11-3. Wind forces cause the four horizontal mounting rods A11-5 to rotate horizontally, driving vertical mounting rods A11-4 to rotate and transmit power to second power generation module A11-6, generating electricity that is then stored in power storage module A11-3. Specifically, power storage module A11-3 is electrically connected to first power generation module A11-2, second power generation module A11-6, controller A6, and drive mechanism A5. The electricity generated by first and second power generation modules A11-2 and A11-6 is stored in power storage module A11-3, which then supplies power to controller A6 and drive mechanism A5. The second power generation module A11-6 and the battery can be protected by a protective cover. The top of the protective cover has an opening for the vertical mounting rod A11-4 to pass through. The bottom of the protective cover is fixed to the top of the cylinder A1 by bolts A10.

[0096] In one embodiment, the first control motor A8-1 and the second control motor can be powered by the first motor battery A8-4 and the second motor battery respectively. The first motor battery A8-4 and the second motor battery are respectively connected to the first power generation module A11-2 and / or the second power generation module A11-6, and are directly powered by the wind power generation component A11 without the need for additional power supply.

[0097] In one embodiment, Figure 17 and Figure 18As shown, wind power generation assembly A11 also includes a first wind vane A11-7, a first wind speed and direction data recording terminal A11-8, a second wind vane A11-9, and a second wind speed and direction data recording terminal A11-10. The first wind vane A11-7 and the first wind speed and direction data recording terminal A11-8 are mounted on a horizontal mounting rod A11-5. The tail of the first wind vane A11-7 is rotatably connected to the horizontal mounting rod A11-5. The first wind speed and direction data recording terminal A11-8 is connected to the first wind vane A11-7 and the wind cup A11-1, respectively. The second wind vane A11-9 and the second wind speed and direction data recording terminal A11-10 are mounted on a vertical mounting rod A11-4. The tail of the second wind vane A11-9 is movably connected to the vertical mounting rod A11-4. The second wind speed and direction data recording terminal is connected to the second wind vane A11-9. Wind cup A11-1 measures wind speed, first wind vane A11-7 measures wind direction relative to the horizontal mounting rod A11-5, and second wind vane A11-9 measures wind direction relative to the vertical mounting rod A11-4. Wind speed and direction data are recorded in first and second wind speed and direction data recording terminals A11-8 and A11-10 and can be sent to controller A6 for analysis and processing. Power can be supplied by either storage module A11-3 or directly from first power generation module A11-2.

[0098] In one embodiment, Figure 19 As shown, the hydraulic energy storage and discharge device 300 of the present invention also includes a satellite data receiving terminal A12. This terminal is mounted on top of a vertical mounting rod A11-4 and is connected to a controller A6. This terminal receives wave energy data from satellite observations and transmits this data to the controller A6, which then generates commands to control the drive mechanism A5, the energy storage valve module A8, and the energy discharge valve module A9 based on the wave energy data.

[0099] In one embodiment, Figures 20 to 21As shown, the waste energy recovery device 500 of the present invention includes a water jet pipe B1, a first power generation assembly B2, and a second power generation assembly B3. The first power generation assembly B2 includes an outer ring stator B2-1, an outer ring rotor B2-2, an outer ring bearing B2-3, an outer ring support B2-4, and a paddle B2-5. The bottom of the inner ring of the outer ring bearing B2-3 is fixedly connected to the top of the outer ring support B2-4. The outer ring rotor B2-2 is mounted on the frame at the top of the inner ring of the outer ring bearing B2-3. The outer ring stator B2-1 is mounted on the frame at the top of the outer ring of the outer ring bearing B2-3. Several vertically mounted paddles B2-5 are fixedly mounted circumferentially on the outer surface of the outer ring support B2-4. The second power generation component B3 includes an inner ring stator B3-1, an inner ring rotor B3-2, an inner ring bearing B3-3, an inner ring support B3-4 and a blade B3-5. The bottom of the inner ring of the inner ring bearing B3-3 is fixedly connected to the top of the inner ring support B3-4. The inner ring rotor B3-2 is installed on the frame at the top of the inner ring of the inner ring bearing B3-3. The inner ring stator B3-1 is installed on the frame at the top of the outer ring of the inner ring bearing B3-3. Several vertically installed blades B3-5 are fixedly installed circumferentially on the bottom side of the inner ring support B3-4. The bottom of the outer ring support B2-4 is higher than the top of the blade B3-5. The blade B3-5 is tilted at a preset angle. The distance from the end of the blade B3-5 to the center of the inner ring support B3-4 is not less than the distance from the end of the paddle B2-5 to the center of the outer ring support B2-4. The inner ring bearing B3-3 is arranged on the inner side of the inner ring of the outer ring bearing B2-3. The water jet outlet of the water jet pipe B1 is aligned with the paddle B2-5.

[0100] It should be noted that the inner ring of the outer ring bearing B2-3 is rotatable. A frame for mounting the outer ring rotor B2-2 is located on top of the inner ring of the outer ring bearing B2-3. The top of the outer ring support B2-4 is connected to the bottom of the inner ring of the outer ring bearing B2-3, allowing it to rotate. The outer ring of the outer ring bearing B2-3 is stationary. A frame for mounting the outer ring stator B2-1 is located on top of the outer ring bearing B2-3. Thus, the outer ring rotor B2-2 and outer ring stator B2-1 form a structure that allows the outer ring rotor B2-2 to rotate and generate electricity by cutting the magnetic flux lines of the outer ring stator B2-1. The inner ring of inner ring bearing B3-3 is rotatable. A frame for mounting inner ring rotor B3-2 is located on top of the inner ring of inner ring bearing B3-3. The top of inner ring support B3-4 is connected to the bottom of the inner ring of inner ring bearing B3-3, allowing inner ring support B3-4 to rotate. The outer ring of inner ring bearing B3-3 is stationary. A frame for mounting inner ring stator B3-1 is located on top of the outer ring of inner ring bearing B3-3. Inner ring stator B3-1 is mounted on top of the frame. Thus, the inner ring rotor B3-2 and inner ring stator B3-1 form a structure that allows the rotation of inner ring rotor B3-2 to generate electricity by cutting magnetic flux lines in inner ring stator B3-1. The jet outlet of the water jet pipe B1 is aimed at the paddle B2-5 of the first power generation assembly B2. Water ejected from the jet outlet strikes the paddle B2-5, providing the thrust that drives the outer ring support B2-4. This in turn drives the rotor on the inner ring of the outer ring bearing B2-3, cutting the magnetic flux lines of the outer ring stator B2-1 at the top of the outer ring of the outer ring bearing B2-3, generating electricity. The paddle B2-5 can be designed as an arc-shaped structure. The water hitting the paddle B2-5 falls under the influence of gravity onto the blades B3-5 of the second power generation assembly B3. Because the blades B3-5 are tilted at a preset angle, the water falling on the blades B3-5 pushes them to rotate horizontally, driving the inner ring support B3-4 to rotate. This in turn drives the inner ring rotor B3-2 at the top of the inner ring of the inner ring bearing B3-3, cutting the magnetic flux lines of the inner ring stator B3-1 at the top of the outer ring of the inner ring bearing B3-3, generating electricity. The waste energy recovery device 500 provided by the present invention further utilizes the concentrated water produced during the desalination process of the seawater desalination device 400, and realizes two-time power generation by utilizing the concentrated water. This improves the energy utilization of the water flow while improving the power generation efficiency, and solves the technical problem that traditional hydroelectric generating sets utilize the energy of the water flow only once, resulting in low water energy utilization efficiency and low power generation efficiency.

[0101] In one embodiment, the preset angle is 15 degrees. The curve of the lift coefficient and drag coefficient of the blade B3-5 of the second power generation component B3 obtained by software simulation as a function of the angle of attack is as follows: Figure 22 As shown, it can be seen that under general conditions, when the angle of attack is 15°, the difference between the lift coefficient and the drag coefficient is the largest, that is, Figure 23 As shown, when the angle of attack is that blade B3-5 is tilted 15 degrees, blade B3-5 can be best pushed to rotate when falling from above blade B3-5 onto blade B3-5.

[0102] In one embodiment, Figure 24 As shown, the second power generation assembly B3 also includes a support baffle B3-6 and a support spring B3-7. These baffles are located between the bottom of the outer ring support B2-4 and the top of the blade B3-5. One end of the support spring B3-7 is fixedly connected to the bottom side of the baffle B3-6 facing the inner ring support B3-4, while the other end is fixedly connected to the side of the inner ring support B3-4. The top of the baffle B3-6 is movably connected to the bottom of the outer ring support B2-4, specifically via a hinge. The bottom of the baffle B3-6 is vertically inclined outward, and the distance from the outermost edge of the baffle B3-6 to the center of the inner ring support B3-4 is less than the distance from the end of the blade B3-5 to the center of the inner ring support B3-4. Multiple baffles B3-6 and support springs B3-7 are provided, circumferentially arranged around the inner ring support B3-4. When the amount of water ejected from the jet outlet is large, the work done by the gravitational potential energy generated by the water falling from the paddle B2-5 acts on the support baffle B3-6. When the support baffle B3-6 is pressed, the connected support spring B3-7 is compressed, and the support baffle B3-6 moves toward the axis of the inner ring support B3-4. This increases the cross-sectional area at the bottom that can accommodate water flow. While ensuring pressure relief, it also increases the contact area between the water flow and the bottom blades B3-5, further enhancing the propulsion effect on the blades B3-5 and accelerating their rotation. When the amount of water ejected from the jet outlet decreases, the support baffle B3-6 returns to its normal position under the reset action of the support spring B3-7, reducing the cross-sectional area at the bottom that can accommodate water flow. This increases the pressure of the water flow on the bottom and improves the thrust of the bottom blades B3-5. At the same time, the water flow now contacts more the outer edge of blade B3-5 (that is, away from the axial direction of the inner ring support B3-4). Under the condition of the same flow rate, more thrust is applied to the outer edge of blade B3-5 than on the inner edge, thereby ensuring the rotation speed of blade B3-5, further ensuring the speed of the inner ring rotor B3-2, and thus ensuring the power generation efficiency.

[0103] In one embodiment, the residual energy recovery device 500 provided by the present invention further includes a pressure regulating device B4, which is installed on the water jet pipe B1 near the water jet outlet. The pressure regulating device B4 is used to adjust the water jet speed of the water jet outlet. The water jet speed of the water jet outlet can be adjusted by pressure regulation, thereby controlling the speed of the outer ring rotor B2-2. Figure 25 As shown, the pressure regulating device B4 comprises a water pipe support frame B4-1, a rotating motor B4-2, a screw B4-3, and an elastic blocking gasket B4-4. The water pipe support frame B4-1 is mounted on the water jetting pipe B1. The output shaft of the rotating motor B4-2 is fixedly connected to one end of the screw B4-3. The other end of the screw B4-3 passes through the water pipe support frame B4-1 and the wall of the water jetting pipe B1, communicating with the interior of the water jetting pipe B1. The end of the screw B4-3 that enters the water jetting pipe B1 is fixedly connected to the elastic blocking gasket B4-4. When the water flow in water jet pipe B1 is low, rotating motor B4-2 controls screw B4-3 to rotate forward, moving screw B4-3 into water jet pipe B1. At this time, elastic blocking gasket B4-4 moves inward, reducing the cross-sectional area of ​​water jet pipe B1 near rotating motor B4-2 and leaving the pipe away from rotating motor B4-2 unoccupied. Consequently, the water flow in water jet pipe B1 increasingly contacts the outer edge of paddle B2-5, pushing it to rotate. This increases the lever arm compared to pushing the inner edge of paddle B2-5, thereby increasing the torque applied to the entire outer ring rotor B2-2 and its speed. When the water flow in water jet pipe B1 is high, rotating motor B4-2 controls screw B4-3 to rotate counterclockwise, moving screw B4-3 outward from water jet pipe B1. The cross-sectional area of ​​water jet pipe B1 near rotating motor B4-2 increases. Since the elastic blocking gasket B4-4 is flexible, when the cross-sectional area of ​​the water jetting pipe B1 near the rotating motor B4-2 is the largest, the entire elastic blocking gasket B4-4 can be completely fitted to the inner wall of the water jetting pipe B1, thereby fully opening the entire water jetting pipe B1. At this time, the water flow in the water jetting pipe B1 can pass more smoothly and stably. In a specific application scenario, the screw B4-3 extends from the pipe wall of the water jetting pipe B1 toward the side of the paddle B2-5 into the water jetting pipe B1. When the entire water jetting pipe B1 is fully opened and the elastic blocking gasket B4-4 moves toward the inside of the water jetting pipe B1, the water ejected from the water jetting outlet can impact the outer edge of the paddle B2-5, thereby increasing the torque on the outer ring rotor B2-2 and thereby increasing the speed of the outer ring rotor B2-2.

[0104] In one embodiment, Figure 21As shown, there are multiple outer ring rotors B2-2, evenly spaced circumferentially distributed on top of the inner ring of the outer ring bearing B2-3. There are also multiple outer ring stators B2-1, evenly spaced circumferentially distributed on top of the outer ring of the outer ring bearing B2-3, improving the power generation efficiency of the first power generation assembly B2. There are also multiple inner ring rotors B3-2, evenly spaced circumferentially distributed on top of the inner ring of the inner ring bearing B3-3, and multiple inner ring stators B3-1, evenly spaced circumferentially distributed on top of the outer ring of the inner ring bearing B3-3, improving the power generation efficiency of the second power generation assembly B3.

[0105] In one embodiment, Figure 26 As shown, the residual energy recovery device 500 provided by the present invention also includes a detachable shell B5, and the water jet outlet of the water jet pipe B1, the first power generation component B2 and the second power generation component B3 are arranged inside the detachable shell B5. The detachable shell B5 is provided to protect the first power generation component B2 and the second power generation component B3 of the residual energy recovery device 500, and prevent the internal components of the residual energy recovery device 500 from being damaged by external factors. The frame at the top of the outer ring of the outer ring bearing B2-3 of the first power generation component B2 can be connected and fixed to the frame at the top of the inner ring of the inner ring bearing B3-3 of the second power generation component B3 through a connecting component. The bottom of the outer ring support B2-4 of the first power generation component B2 is suspended. The bottom of the inner ring support B3-4 of the second power generation component B3 can be movably connected to the inner bottom of the detachable shell B5 through a movable connecting piece.

[0106] In one embodiment, the waste energy recovery device 500 further includes a water recovery device, which is installed below the second power generation component B3. The water recovery device is used to collect water that falls below the second power generation component B3, thereby collecting water for power generation.
