At present, most mainstream hydropower generation devices are traditional hydroelectric power stations, whose core power generation principle relies on the difference in water level formed by natural terrain such as dams, lakes, and rivers.

The generator gear transmission mechanism relies on the impact of water flow for drive, and the speed is difficult to increase effectively, which directly results in low power generation efficiency. At the same time, the gear transmission mechanism of existing generators does not have a matching self-lubricating structure. During the operation of the gear transmission mechanism, the parts wear out severely, which not only further reduces the power generation efficiency, but also significantly shortens the overall service life of the generator.

[0015] The beneficial effects of this invention are: First, the variable speed gear module is assembled using a two-stage speed-up structure. The two stages work together to amplify the rotational speed step by step. After the water flow drives the drive module to output the initial speed, the two stages of continuous speed increase by the variable speed gear module can amplify the output speed of the drive module twice, significantly increasing the rotational speed input to the power generation module. Under the same water flow impact and the same kinetic energy output of the drive module, the power generation module can maintain a higher operating speed, effectively improving the energy conversion efficiency of the power generation module per unit time and greatly improving the power output of the power generation module.

[0016] Secondly, the transmission gear module integrates a self-lubricating structure, continuously supplying lubricating medium to all components during operation. This significantly improves the smoothness of component operation, reducing transmission jamming and ensuring stable and smooth power transmission. Furthermore, it effectively reduces frictional resistance generated by the meshing and rotational contact of components, minimizing frictional losses and significantly reducing wear, scratches, and fatigue damage caused by long-term operation. This reduces kinetic energy loss during transmission, improves the overall power transmission efficiency of the transmission gear module, indirectly optimizing the overall power generation efficiency, and delays aging and damage to components, effectively extending the overall service life of the transmission gear module and reducing the probability of equipment failure and the frequency of subsequent maintenance and replacement.

[0017] Third, a cooling component is installed to continuously and in real time cool down the transmission gear module during operation. This effectively removes the frictional heat generated during meshing and power transmission, keeping the internal working temperature of the transmission gear module within a reasonable range. This avoids problems such as dilution of the self-lubricating medium due to excessive internal temperature, significant reduction in lubrication performance, and oil deterioration and sludge formation at high temperatures. It ensures stable meshing and transmission of internal components of the transmission gear module, maintains the high-efficiency power transmission performance of the transmission gear module, and stabilizes the overall power generation efficiency. Meanwhile, the cooling component directly uses water as the power and heat exchange medium, and relies on the natural flow of water to drive the entire operation. There is no need to add external drive equipment such as cooling motors and independent power pumps. This not only saves the power supply consumption, but also significantly reduces the daily energy consumption and maintenance costs of the equipment. It also reduces the number of parts assembled in the whole machine, simplifies the overall equipment structure, reduces the difficulty of equipment processing and assembly, and reduces the overall construction cost of the project from the source.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The background of this invention is that the power generation efficiency of existing hydroelectric power stations still has significant room for improvement. The shortcomings are concentrated on the generator gear speed. The generator gear transmission mechanism relies on water flow impact for drive, making it difficult to effectively increase the speed, directly resulting in low power generation efficiency. At the same time, the existing generator gear transmission mechanism does not have a matching self-lubricating structure, and the gear transmission mechanism components wear out severely during operation, which not only further reduces power generation efficiency but also significantly shortens the overall service life of the generator. The technical solution of this invention is to solve the problems of existing hydroelectric generator gear transmission mechanisms relying solely on water flow impact for drive, resulting in low speed, low power generation efficiency, and the lack of a self-lubricating structure in the gear transmission mechanism, leading to severe wear during operation, continuously reducing power generation efficiency and shortening equipment lifespan. Please see Figures 1-6 , Figure 9As shown, this embodiment is a wave-driven water circulation booster power generation device, comprising: a power generation component consisting of a water energy unit and a power generation unit; the water energy unit includes a high-level reservoir 13 and a low-level reservoir 11 arranged at different heights (both the high-level reservoir 13 and the low-level reservoir 11 are concrete water tank structures or steel structure water tanks, wherein the low-level reservoir 11 is connected to the ocean through an inlet channel, and wave energy drives water to naturally flow into the water storage chamber of the low-level reservoir 11, and the water storage chamber of the high-level reservoir 13 has a volume greater than the single circulation water volume to ensure continuous and stable water release), a connecting strip 12 fixed between the high-level reservoir 13 and the low-level reservoir 11, and a water outlet pipe 14 assembled at the bottom of the high-level reservoir 13 and connected to the water storage chamber of the high-level reservoir 13, wherein the water outlet pipe The outlet of 14 faces the low-level reservoir 11, and its center is coaxially arranged with the center of the low-level reservoir 11. The water energy unit also includes four sets of pump modules equidistantly arranged on the right side of the low-level reservoir 11. The pump module includes a water conveying pipe 15 installed on the right side of the low-level reservoir 11 and connected to the water storage chamber of the low-level reservoir 11, wherein the outlet of the water conveying pipe 15 faces the inside of the water storage chamber of the high-level reservoir 13. The pump module also includes a dual-pressure water hammer pump. The dual-pressure water hammer pump is composed of a valve 16, two sets of drain valves 17, and a pressure tank 18 sequentially installed on the outer wall of the water conveying pipe 15. The power generation unit is composed of a power generation module, a drive module, and a speed-changing gear module. The power generation module includes a platform fixed to the outer wall of the outlet pipe 14. 211, a generator 210 mounted on the top of platform 211; a drive module, the drive module including two sets of first mounting holes 21 respectively opened on the front and rear sides of the water outlet pipe 14, two sets of first bearings 22 respectively mounted inside the two sets of first mounting holes 21, a first drive rod 23 fixed to the inner ring of the two sets of first bearings 22, a first turbine 223 fixed to the outer wall of the first drive rod 23 and located inside the water outlet pipe 14, wherein the first turbine 223 is driven by the impact of the water flowing downward inside the water outlet pipe 14, and the first drive rod 23 rotates synchronously when the first turbine 223 rotates; a transmission gear module, the transmission gear module including a housing 212 fixed on the top side of platform 211, and second mounting holes 216 respectively opened on the rear side of housing 212. The third mounting hole 218 houses the second bearing 217, which is installed inside the second mounting hole 216. The first drive rod 23 is fixed to the inner ring of the second bearing 217, and its end is fixed to the first gear 24 located inside the housing 212. The gear transmission module also includes a second gear 25 meshing with the first gear 24, a third gear 27 fixed to the end face of the second gear 25 by the second drive rod 26, a fourth gear 28 meshing with the third gear 27, and a third drive rod 29 fixed to the end face of the fourth gear 28, whose end movably passes through the third mounting hole 218 and is connected to the rotor shaft of the generator 210. The third mounting hole 218 houses the third bearing 219, and the third drive rod 29 is fixed to the inner ring of the third bearing 219.The transmission gear module also includes a support plate 213 vertically fixed inside the housing 212, a fourth mounting hole 214 formed on the end face of the support plate 213, and a fourth bearing 215 assembled inside the fourth mounting hole 214, wherein the second drive rod 26 is fixed to the inner ring of the fourth bearing 215.

[0022] Water is transported to the storage chamber of the low-level reservoir 11 by utilizing the characteristics of wave energy. With the help of the dual-pressure water hammer pump, the water level difference between the low-level reservoir 11 and the dual-pressure water hammer pump (which works by utilizing the water hammer effect: two sets of drain valves 17 alternately and rapidly open and close, causing periodic pressure fluctuations in the water supply pipeline 15, and the pressure tank 18 storing pressure energy and outputting it smoothly, lifting and transporting the water in the storage chamber of the low-level reservoir 11 to the storage chamber of the high-level reservoir 13), the water in the storage chamber of the low-level reservoir 11 is sent to the storage chamber of the high-level reservoir 13 through the water supply pipeline 15. The water in the storage chamber of the high-level reservoir 13 then flows back down to the storage chamber of the low-level reservoir 11 through the outlet pipe 14, thus realizing a closed-loop water circulation. During the water falling and flowing back, the impact drive module operates, and the drive module is driven by the speed-changing gear module to drive the power generation module to complete the power generation. This invention operates solely on natural marine hydropower, water level differences, and dual-pressure water hammer pumps. Compared to traditional small pumped storage power stations, it requires no external power supply and can be used for independent power supply in nearshore and island areas without grid coverage. Compared to traditional elevation-based hydropower generation, it does not require specific elevation terrain, has strong terrain adaptability, and low site dependence.

[0023] Specifically, a low-storage reservoir 11 and a high-storage reservoir 13 are constructed in a designated area. Water is transported to the storage chamber of the low-storage reservoir 11 using wave energy characteristics. With the help of a dual-pressure water hammer pump, the water level difference between the low-storage reservoirs 11, and the synergistic effect of the dual-pressure water hammer pump, the water in the storage chamber of the low-storage reservoir 11 is sent to the storage chamber of the high-storage reservoir 13 through the water delivery pipe 15. The water in the storage chamber of the high-storage reservoir 13 then flows back down to the storage chamber of the low-storage reservoir 11 through the outlet pipe 14, thus achieving a closed-loop water circulation. During the water's fall and return flow, it impacts the first turbine 223. The first turbine 223 drives the first gear 24 to rotate through the first drive rod 23. The first gear 24 meshes with and transmits the second gear 25. The second gear 25 drives the third gear 27 to rotate through the second drive rod 26. The third gear 27 then drives the fourth gear 28. The fourth gear 28 transmits the generator 210 through the third drive rod 29 to achieve power generation.

[0024] Among them, the first bearing 22, the second bearing 217, and the third bearing 219 all adopt a sealed structure, which can effectively prevent media leakage.

[0025] Please see Figures 4-6As shown, the transmission gear module integrates a self-lubricating structure, which includes an oil inlet pipe 220 and an oil outlet pipe 221 respectively mounted on the top and bottom sides of the housing 212 and respectively communicating with the inner cavity of the housing 212; both the oil inlet pipe 220 and the oil outlet pipe 221 are pipes with a threaded structure on the inner wall; both the oil inlet pipe 220 and the oil outlet pipe 221 are equipped with a sealing structure; the sealing structure includes a threaded plug threaded inside the oil inlet pipe 220 and the oil outlet pipe 221, and a rotating shaft 222 fixed at the end of the threaded plug; the rotating shaft 222 is used to unscrew the threaded plug from the oil inlet pipe 220, so that the threaded plug is separated from the oil inlet pipe 220, and lubricating oil is added to the inside of the housing 212 through the oil inlet pipe 220, thereby lubricating the first gear 24, the second gear 25, the third gear 27, and the fourth gear 28.

[0026] The gear transmission module integrates a self-lubricating structure, continuously supplying lubricating medium to all components during operation. This significantly improves the smoothness of component operation, reducing transmission jamming and ensuring stable and smooth power transmission. Furthermore, it effectively reduces frictional resistance generated by the meshing and rotational contact of components, minimizing frictional losses and significantly mitigating wear, scratches, and fatigue damage from long-term operation. This reduces kinetic energy loss during transmission, improves the overall power transmission efficiency of the gear transmission module, indirectly optimizing the overall power generation efficiency, and delays aging and damage to components, effectively extending the overall service life of the gear transmission module and reducing the probability of equipment failure and the frequency of subsequent maintenance and replacement.

[0027] Specifically, the operator first rotates the rotating shaft 222 to separate the threaded plug from the oil inlet pipe 220, and then adds lubricating oil into the housing 212 through the oil inlet pipe 220 to lubricate the first gear 24, the second gear 25, the third gear 27, and the fourth gear 28.

[0028] The outer diameter of the first gear 24 is greater than that of the second gear 25; the outer diameter of the third gear 27 is greater than that of the fourth gear 28.

[0029] The variable speed gear module is assembled using a two-stage speed-up structure. These two stages work in sequence to amplify the rotational speed step by step. After the water flow drives the drive module to output its initial speed, the variable speed gear module continuously increases the speed twice, significantly raising the rotational speed input to the power generation module. Under the same water flow impact and the same kinetic energy output from the drive module, the power generation module can maintain a higher operating speed, effectively improving its energy conversion efficiency per unit time, significantly increasing its power output, fully utilizing the hydrodynamic energy contained in the underwater flow, and improving the overall utilization efficiency of ocean wave energy.

[0030] Specifically, the outer diameter of the first gear 24 is larger than that of the second gear 25. After transmission, the speed of the second gear 25 is higher than that of the first gear 24, forming a first-stage speed-up structure. Similarly, the outer diameter of the third gear 27 is larger than that of the fourth gear 28. The speed of the fourth gear 28 is higher than that of the third gear 27, forming a second-stage speed-up structure. The two-stage speed-up structures are connected in series to achieve a step-by-step increase in speed, effectively improving the power generation efficiency of the generator 210.

The outer diameter of the sixth gear 314 is larger than the outer diameter of the fifth gear 39.The top side of the push rod 321 corresponds to one of the tooth slots of the sixth gear 314. The locking module includes a mounting base 328 fixed to the end face of the L-shaped seat 311; a locking strip 330 hinged to the mounting base 328 by a hinge pin 329 and engaged within one of the tooth slots of the sixth gear 314; and a torsion spring 333 sleeved on the outside of the hinge pin 329. Both ends of the torsion spring 333 abut against the top side of the limiting plate 332 fixed inside the mounting base 328. The push rod 321 moves upward and abuts against one of the tooth slots of the sixth gear 314, forming an inner bottom side of the abutment groove 331 on the inner wall of the mounting base 328. This pushes the sixth gear 314 to rotate counterclockwise around the corresponding angle of that single tooth slot. The locking bar 330 first separates from the original tooth slot of the sixth gear 314. As the sixth gear 314 continues to rotate, the locking bar 330 re-engages into another adjacent tooth slot on the counterclockwise rotation side of the original tooth slot, thus locking the sixth gear 314.

[0032] Equipped with a cooling system, the system continuously and in real-time cools the transmission gear module during operation, effectively removing the frictional heat generated during meshing and power transmission, and controlling the internal operating temperature of the transmission gear module within a reasonable range. This prevents problems such as dilution of the self-lubricating medium due to heat, significant reduction in lubrication performance, and sludge formation caused by oil deterioration and accumulation at high temperatures. It ensures stable meshing and transmission of internal components of the transmission gear module, continuously maintains the high-efficiency power transmission performance of the transmission gear module, and stabilizes the overall power generation efficiency.

[0033] Meanwhile, the cooling component directly uses water as the power and heat exchange medium, and relies on the natural flow of water to drive the entire operation. There is no need to add external drive equipment such as cooling motors and independent power pumps. This not only saves the power supply consumption, but also significantly reduces the daily energy consumption and maintenance costs of the equipment. It also reduces the number of parts assembled in the whole machine, simplifies the overall equipment structure, reduces the difficulty of equipment processing and assembly, and reduces the overall construction cost of the project from the source. The cooling component directly uses water as the power and heat exchange medium. It relies on the falling water flow to drive the third turbine 317 to rotate, and then drives the second turbine 310 to operate through the reciprocating module and the locking module. The entire process is driven by the natural water flow, without the need for additional external drive equipment such as cooling motors or independent power pumps.

[0034] Specifically, the underwater backflow impacts the third turbine 317, which drives the rotating disk 318 to rotate via the fifth drive rod 316. During the rotation of the rotating disk 318, the movable bar 319 is linked, causing the push rod 321 to reciprocate up and down along the linear bearing 320. When the push rod 321 moves upward, it extends into and engages with the tooth groove of the sixth gear 314, pushing the sixth gear 314 to rotate counterclockwise by a single tooth at the corresponding angle. The sixth gear 314 simultaneously drives the fifth gear 39 to rotate, and the fifth gear 39 drives the second turbine 310 to operate within the negative pressure shroud 34 via the fourth drive rod 38. The rotation of the second turbine 310 creates negative pressure inside the negative pressure shroud 34 (the second turbine 310 is a centrifugal impeller structure; when it rotates, it generates centrifugal force to expel air from inside the negative pressure shroud 34, creating negative pressure inside the shroud 34, thereby drawing low-temperature water from the storage chamber of the low-temperature reservoir 11 into the cooling shroud 31 via the cold water inlet pipe 32). The low-temperature water in the storage chamber of the low-temperature reservoir 11 flows into the cooling shroud 31 via the cold water inlet pipe 32, then into the negative pressure shroud 34 via the first cold water outlet pipe 33, and finally flows back to the storage chamber of the low-temperature reservoir 11 via the second cold water outlet pipe 35, forming a water circulation loop. The circulating low-temperature water continuously removes heat from the side wall of the housing 212, thereby cooling the lubricating oil, the first gear 24, the second gear 25, the third gear 27, and the fourth gear 28.

[0035] During the process of the push rod 321 pushing the sixth gear 314 to rotate counterclockwise through the angle corresponding to a single tooth, the locking strip 330 first disengages from the tooth groove currently meshing with the sixth gear 314. After the sixth gear 314 continues to rotate, the locking strip 330 is engaged in the adjacent tooth groove on the counterclockwise side of the tooth groove under the elastic force of the torsion spring 333, thereby limiting and locking the sixth gear 314 and preventing the sixth gear 314 from rotating loosely during the reciprocating lifting and lowering of the push rod 321, thus ensuring the continuous and stable heat dissipation of the housing 212. Among them, the fifth bearing 37 and the sixth bearing 315 both adopt a sealed structure, which can effectively prevent media leakage; The enclosure 212 is made of thermally conductive material.

[0036] Please see Figure 8 As shown, the cooling unit also includes a heat conduction component; the heat conduction component includes four sets of connecting slots 334 equidistantly opened on the front side of the housing 212, and four sets of heat conduction frames 335 respectively assembled inside the four sets of connecting slots 334, wherein the four sets of heat conduction frames 335 protrude from the interior of the cooling cover 31.

[0037] Specifically, four sets of heat conduction frames 335 are provided. The interior of the four sets of heat conduction frames 335 can hold lubricating oil, and the four sets of heat conduction frames 335 protrude from the interior of the cooling cover 31. This increases the heat exchange contact area between the lubricating oil and the low-temperature water inside the cooling cover 31, effectively enhancing the cooling effect of the lubricating oil. The heat conduction frame 335 is made of a thermally conductive material.

[0038] Please see Figure 1 , Figure 3 , Figure 9 , Figure 11 , Figure 14 As shown, the reciprocating module also includes a clearance component; the clearance component includes a fixed plate 322 fixed to the top side of the top rod 321, a through hole 323 opened on the end face of the fixed plate 322, a movable rod 324 movably passing through the through hole 323, a top block 326 and a limiting plate 325 respectively fixed to both ends of the movable rod 324, and a spring 327 sleeved on the outside of the movable rod 324 and whose two ends are respectively fixed to the fixed plate 322 and the top block 326 facing one end.

[0039] Specifically, when the push rod 321 rises upward and pushes the sixth gear 314 to rotate counterclockwise through the corresponding angle of a single tooth, the push block 326 first contacts the tooth groove of the sixth gear 314. The sixth gear 314 continues to rotate counterclockwise, and its adjacent tooth grooves press against the push block 326, causing the push block 326 to move to the right to avoid interference and ensure the smooth rotation of the sixth gear 314. Simultaneously, the spring 327 is compressed. After the push rod 321 returns to its original position, the spring 327 rebounds and drives the push block 326 to return to its original position, completing the preparation for the next round of transmission operation.

[0040] In summary, the overall workflow of this invention is as follows: ocean waves drive water into the low reservoir 11, and the water in the low reservoir 11 is pressurized by a dual-pressure water hammer pump and then transported to the high reservoir 13 for storage; the water in the high reservoir 13 flows back down to the low reservoir 11 through the outlet pipe 14, forming a closed loop; the falling water flow sequentially impacts the first turbine 223 and the third turbine 317 in the outlet pipe 14, driving the gear transmission module to increase speed in two stages and then driving the generator 210 to generate electricity; at the same time, the cooling component uses water circulation to cool the gear transmission module in real time.

[0041] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
