DETAILED DESCRIPTION
[0031] The present invention will now be described in further detail with reference to the accompanying drawings.
[0032] Example 1: Please refer to Figure 1-3 As shown, in this embodiment, a split inertial kinetic energy oscillation system is provided, including a housing 1, wherein the housing 1 has an upper chamber 22 and a lower chamber 20, and the diameter of the lower chamber 20 is smaller than the diameter of the upper chamber 22;
[0033] An inertial kinetic energy body 2, wherein the inertial kinetic energy body 2 slides vertically in the lower cavity of the shell 1, and can oscillate up and down to generate inertial kinetic energy under the impetus of the ups and downs of the ocean waves; and a suspension support system 3 is provided below the inertial kinetic energy body 2, and is arranged in the lower cavity 20, and the suspension support system 3 is used to support the oscillating inertial kinetic energy body 2;
[0034] The mounting structure 23 is located in the upper chamber 22. A transmission mechanism 4 is arranged above the mounting structure 23. The transmission part of the transmission mechanism 4 passes through the mounting structure 23 and enters the lower chamber 20 to connect with the inertial kinetic energy body 2. The transmission mechanism 4 can convert the bidirectional reciprocating oscillation kinetic energy of the inertial kinetic energy body 2 into a continuous torque with a unidirectional output.
[0035] In this embodiment, the suspension support system 3 has an elastic structure 5, and the elastic structure 5 is in an elastic energy storage state. The elastic force provided by the elastic structure 5 is used to directly or indirectly serve as a supporting force for supporting the oscillating suspension body.
[0036] In this embodiment, the transmission mechanism 4 includes a mounting plate 6, an energy storage balance flywheel 7, a double-sided rack 8 and a torque conversion gear set located above the transmission structure. The torque conversion gear set is mounted on one side of the mounting plate 6. The energy storage balance flywheel 7 rotates inside the upper chamber 22. One end of the rack 8 is fixed to the inertial kinetic energy body 2. The double-sided rack 8 is meshed with two sets of torque conversion gear sets respectively, and the output end of the torque conversion gear set cooperates with the energy storage balance flywheel 7. The double-sided rack 8 has gear teeth on both sides and meshes with the second gear 15.
[0037] In this embodiment, the torque conversion gear set includes a first transmission shaft 9, a second transmission shaft 10, a third transmission shaft 11, and a fourth transmission shaft 12 which are rotatably connected to the four corners of the mounting plate 6 respectively. The first transmission shaft 9 and the second transmission shaft 10 are fixedly connected to two first gears 13 on their circumferential sides. The first transmission shaft 9 and the second transmission shaft 10 are also fixedly connected to a second gear 14 located between the two first gears 13 on their circumferential sides. The rack 8 is located between the two second gears 14 and meshes with the two second gears 14, and meshes with two adjacent first gears 13. The third transmission shaft 11 and the fourth transmission shaft 12 are rotatably connected to two third gears 15 on their circumferential sides, and the third gears 15 are meshed with the first gear 13.
[0038] In this embodiment, a rotating shaft 16 is connected to one side of the energy storage balance flywheel 7, one end of the rotating shaft 16 is fixedly connected to two fourth gears 17, the other end of the rotating shaft 16 is rotatably connected to the inner wall of the upper chamber 22, and the ends of the third transmission shaft 11 and the fourth transmission shaft 12 of the rotating shaft 16 away from the third gear 15 are fixedly connected to the fifth gear 18, and the two fifth gears 18 are respectively meshed with the two fourth gears 17. The two second gears 18 at the third transmission shaft 11 and the fourth transmission shaft 12 are staggered.
[0039] In this embodiment, the third transmission shaft 11 and the fourth transmission shaft 12 are both rotatably connected to one side of the mounting plate 6 using a one-way bearing 19. The one-way bearing 19 can convert bidirectional reciprocating kinetic energy into a continuous torque output in one direction and drive the energy storage balance flywheel 7.
[0040] In this embodiment, the mounting structure 23 includes two transverse partitions 24 located on the inner wall of the shell 1 from top to bottom, and the opposite sides of the two transverse partitions 24 are penetrated by through grooves 21 for the rack 8 to slide, wherein the upper surface of the upper transverse partition 24 is fixedly connected to the bearing seat 25, and the rotating shaft 16 is rotatably connected to the inside of the bearing seat 25, and a vertical partition 26 is arranged between the two transverse partitions 24.
[0041] By arranging the inertial kinetic energy body 2, the transmission system and the supporting structure in the upper cavity and the lower cavity respectively, the center of gravity of the wave energy power generation device can be lowered, so that the overall movement center of gravity of the device is always kept at the lowest point. This low center of gravity characteristic greatly enhances the stability of the device when floating on the sea. In the violent ups and downs of waves, especially in extreme weather conditions such as typhoons and huge waves, the device can reduce the risk of tilting or capsizing caused by wave impact, thereby ensuring that the device can work stably for a long time and efficiently capture wave energy.
[0042] In similar offshore wave energy capture devices, due to the high center of gravity, the device is easily impacted by waves, especially under extreme sea conditions such as typhoons or huge waves, the device may capsize or seriously tilt, affecting its normal operation. The split design lowers the overall center of gravity of the device by separating the inertial kinetic energy body 2 from other components, allowing the device to float more stably on the water. In this way, even in an environment with strong winds and huge waves, the device can maintain a low tilt angle, reduce the risk of uneven force, and avoid capsizing or damage due to the violent ups and downs of waves.
[0043] In addition, the low center of gravity design not only improves the stability of the device, but also significantly optimizes the kinetic energy capture efficiency of the device. The kinetic energy of the waves is converted into oscillating kinetic energy within the system, and is converted into continuous power output through the repeated oscillation of the inertial kinetic energy body 2 and the mechanical system. Due to the lower center of gravity, the floating amplitude of the device under the impact of waves is reduced, and the kinetic energy in the waves can be captured more accurately, which reduces the mismatch between the device and the waves and improves the kinetic energy conversion efficiency.
[0044] The split design is also more adaptable when dealing with extreme weather or sea conditions. Extreme sea conditions such as typhoons and huge waves usually cause damage or malfunction of traditional equipment because the equipment cannot withstand the huge water pressure and impact force from different directions. The split design system, due to its low center of gravity, can effectively disperse external pressure, allowing the equipment to maintain a stable working state when facing strong waves. Especially in high wave conditions, the split structure allows each component to move independently without interfering with each other. This flexibility effectively reduces the risk of damage to the equipment due to excessive overall force.
[0045] In addition, due to the good independence and modularity of the split design, even in extreme weather conditions, if a part of the equipment fails, the entire system can continue to operate and maintain high energy output. This high reliability and maintainability is unmatched by traditional equipment, providing a more stable and long-term operation guarantee for offshore wave energy generation.
[0046] Working principle: When the inertial kinetic energy body 2 oscillates, the vibration of the inertial kinetic energy body 2 is converted into a reciprocating force through the mechanical system. This oscillating motion is connected to the inertial kinetic energy body 2 through the connection of the rack 8. One end of the rack 8 is fixed on the inertial oscillating body, so the rack 8 oscillates up and down when the inertial kinetic energy body 2 moves up and down. The up and down vibration of the rack 8 will drive the two groups of gears A and B meshed thereon to rotate. When the rack rises, the gear group A generates a positive torque and transmits the positive torque to the flywheel. At this time, the one-way bearing of the gear group B rotates idly, and the other gears of the gear group B do not rotate; when the rack descends, the gear group B generates a positive torque and transmits the torque to the flywheel. At this time, the one-way bearing of the gear group A rotates idly, and the other gears of the gear group A do not rotate, so that when the rack moves up and down with the inertial kinetic energy body, the kinetic energy of the up and down movement of the inertial kinetic energy body is transmitted to the flywheel.
[0047] It should be noted that: Group A gears are all gears at the second transmission shaft 10 and the fourth transmission shaft 12, Group B gears are all gears at the first transmission shaft 9 and the third transmission shaft 11, and Group A gears are Figure 3 There are two transmission shafts on the right side, and the gears in group B are Figure 3 The upper and lower transmission shafts on the left side;
[0048] That is, when the double-sided rack 8 moves upward, the rack 8 will mesh with the second gear 14 on the side of the second transmission shaft 10, and then the second gear 14 will rotate with the second transmission shaft 10. During the rotation of the second transmission shaft 10, the first gear 13 on the side of the second transmission shaft 10 will rotate. Subsequently, the first gear 13 will drive the third gear 15 on the side of the fourth transmission shaft 12 to rotate. At the same time, since the third gear 15 transmits force, the fourth transmission shaft 12 will rotate, and the fifth gear 18 on the side of the fourth transmission shaft 12 will rotate at the same time, and drive the rotating shaft 7 to rotate by meshing with the fourth gear 17. In the process of realizing this transmission, the one-way bearing of group B gears rotates idly, and other gears of group B do not rotate. The same is true when the double-sided rack 8 descends.
[0049] For further explanation: the rotation direction of the one-way bearings at the third transmission shaft and the fourth transmission shaft is both clockwise.
[0050] The two gear sets are a torque conversion system composed of a one-way bearing 19. Each gear set controls the direction of the transmitted torque through the one-way selective function of the one-way bearing 19. Specifically, the function of the one-way bearing 19 is to allow the force in one direction to be transmitted smoothly, while filtering the force in the other direction. In this way, the bidirectional torque generated when the rack 8 moves up and down will be output selectively in one direction after conversion by the two gear sets, ensuring that the final power output direction is consistent.
[0051] Example 2, please refer to Figure 4-6As shown, a chain 27 is used to drive the inertial kinetic energy body 2 to slide up and down in the lower chamber 20, and its structural layout is as follows: the rack in the transmission mechanism is replaced by a chain 27, and a lower sprocket 28 is provided at the bottom below the lower chamber. The first end of the chain 27 bypasses the connection fixed on the transverse partition 24 and is fixedly connected to the upper part of the inertial kinetic energy body 2 downward, and the second end bypasses the bottom lower sprocket 28 and is fixedly connected to the lower part of the inertial kinetic energy body 2, thereby forming a chain closed loop, and the circumferential side of the second transmission shaft 10 is also fixedly connected to an upper sprocket located between the two first gears 13 29, the chain 27 is connected to the lower end of the inertial kinetic energy body, and the other end of the chain 27 passes through the sprocket on the upper end transmission shaft and is fixed to the upper part of the inertial kinetic energy body to form a closed chain 27, and the chain 27 cooperates with the upper sprocket 29 and the lower sprocket 28. During the implementation of Example 2, the second gear 14 needs to be replaced with the upper sprocket 29 and the first transmission shaft 9 is removed. In addition, the first gear 13 at the second transmission shaft and the two third gears 15 are meshed. In addition, a straight groove is provided between the upper and lower parts of the inertial kinetic energy body 2 for the chain 27 to pass through. The other content and structural design are the same as those of Example 1.
[0052] When the inertial kinetic energy body oscillates up and down, the chain 27 rotates under the drive of the inertial kinetic energy body, driving the upper sprocket to rotate the transmission shaft in both directions, which is the same as embodiment 1, and finally realizes full-time continuous torque output. The sprocket stroke is closed and fixed to transmit the vertical oscillation kinetic energy of the inertial kinetic energy body to the transmission mechanism through the rack or chain 27, and the transmission mechanism converts the bidirectional reciprocating vertical kinetic energy into a unidirectional torque output, driving the generator to rotate.

Anyone should be aware that any structural changes made under the enlightenment of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention.
