Description

Technical Field

[0001] The present invention relates to the technical field of wave energy power generation, and in particular to a single-rocker-arm oscillating float type wave energy power generation device and an installation method thereof. Background Art

[0002] Currently, most wave energy power generation devices on the market are of the oscillating water column type, pendulum type, and oscillating float type. Due to the high conversion efficiency of gear transmission and its simplicity and reliability, they have been widely used. Oscillating float wave energy power generation devices based on gear transmission mechanisms can be further subdivided into gear rack vertical oscillation wave energy conversion devices and rocker swing wave energy power generation devices. Rocker swing wave energy power generation devices use floats on the water surface to move up and down with the waves, absorbing the energy of the up and down movement of the waves. Then, through an energy conversion mechanism connected to the rocker arm (including mechanical transmission mechanism, hydraulic transmission mechanism, etc.), this converts the wave energy into rotational mechanical energy. However, current rocker swing wave energy power generation devices, especially the mechanical transmission method, still have some problems and need further improvement and perfection.

[0003] Patent CN118934413A discloses an offshore wave energy power generation device, including an offshore platform, an energy conversion mechanism, including a generator provided on the offshore platform, a gear set provided on the generator, and a drive shaft provided on the gear set; a rotating mechanism, including a housing provided on the offshore platform, and a rotating wheel provided in the housing, wherein a coil spring is provided in the rotating wheel. After the coil spring is used to connect the drive shaft and the rotating wheel, when the rotating wheel rotates, the starting process of the generator slows down. When the rotating wheel rotates intermittently, it can have a certain buffering capacity, and the coil spring gradually releases the force and energy, so that the rotation of the generator lasts longer. However, the above-mentioned offshore wave energy power generation device still has the following major defects and problems: 1. The movement of the floating barrel will push the one-way push arm to perform a rotational motion that alternates between forward and reverse rotation. The rotating wheel can only rotate in one direction due to the limitation of the one-way locking part. During the rotation process, the one-way push arm can only push the rotating wheel in one direction, that is, the movement generated by the waves can only intermittently push the rotating wheel to rotate in one direction. Therefore, the above-mentioned offshore wave energy power generation device can only capture the energy generated in a single stroke of the one-way push arm's forward and reverse rotation. As a result, a lot of captured energy is lost, and when the wave height on the sea surface is low, the coil spring is slightly compressed, making it difficult to drive or even impossible to drive the gear set and generator, causing the generator to turn and stop intermittently, thereby shortening the service life of the generator and low power generation efficiency.

[0004] 2. Due to the limitation of the one-way locking member, the rotating wheel can only rotate in one direction, and its operating speed fluctuates greatly. In addition, the compression absorption and extension release of the coil spring cannot achieve the effect of smoothing the rotation of the generator rotor. It can only play a buffering role, but cannot play a role in speed balancing. As a result, it is impossible to ensure that the speed unevenness coefficient of the generator main shaft is within the allowable value range specified in the national standard GB / T 755. As a result, the generator cannot generate electricity normally, which seriously affects the power generation efficiency.

[0005] 3. The overall structure of the above-mentioned offshore wave energy power generation device is relatively complex, especially the one-way locking mechanism of the coil spring and the rotating wheel, which requires high installation precision. The manufacturing, installation, and subsequent disassembly and maintenance of the device are quite difficult. Summary of the Invention

[0019] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0020] For easier understanding, see Figure 1 、 Figure 2 and Figure 11This embodiment provides a single rocker arm 2 oscillating float 1 type wave energy power generation device and its installation method, including a float 1, a rocker arm 2, a transmission box 3, a coupling 4, a transmission 5, a flywheel 6 and a generator 7. The transmission box 3, the transmission 5 and the generator 7 are all fixedly mounted on a fixed frame 8. Specifically, the fixed frame 8 is provided with four vertical transmission fixing holes 8.3. Bolts are passed through the transmission 5 and the transmission fixing holes 8.3 to achieve relative fixation between the transmission 5 and the fixed frame 8, and six generator bolts 8.4 are used to achieve relative fixation between the generator 7 and the fixed frame 8. Four vertical floating frame connection holes 8.2 are provided on the fixed frame 8. Through the floating frame connection holes 8.2, the fixed frame 8 can be installed on an offshore floating frame or on a dedicated offshore fixed truss. The weight of float 1 is less than the buoyancy generated by its volume, so it floats on the sea surface. When a wave passes through the area where float 1 is placed, float 1 can follow the wave's movement. Specifically, float 1 rises from the sea surface on the wave's front side and descends to the sea surface on the wave's back side. In other words, when the wave excites float 1, it absorbs wave energy and produces an up-and-down motion that follows the wave. Float 1 is connected to the left end of rocker arm 2, the right end of which is connected to transmission case 3. Transmission case 3 is connected to transmission 5 via coupling 4. Transmission 5 is a step-up transmission 5, comprising a low-speed shaft at the input and a high-speed shaft at the output. Output shaft 3.10 of transmission case 3 is connected to the low-speed shaft of transmission 5 via coupling 4. Transmission 5 steps up the rotational speed of output shaft 3.10, increasing the speed to the required power generation speed. This speed is then transmitted via the high-speed shaft of transmission 5 to the main shaft of generator 7, generating electricity. The flywheel 6 is installed between the transmission 5 and the generator 7. The center hole of the flywheel 6 is connected to the high-speed shaft of the transmission 5 and the main shaft of the generator 7 at the same time. The flywheel 6 is used as an energy storage element to balance the rotation speed, further making the rotation speed of the main shaft of the generator 7 reach the allowable range of the speed unevenness coefficient, ensuring that the generator 7 can operate normally and generate electricity during the entire wave energy capture process.

[0021] As the buoy 1 rises and falls with the waves, the rocker arm 2 performs a bidirectional rotational motion (also called swinging) about the inner gear ring 3.1 of the transmission case 3, alternating between forward and reverse rotation (clockwise and counterclockwise). The transmission case 3 converts this bidirectional rotational motion transmitted by the rocker arm 2 into unidirectional rotational motion. This converts the bidirectional swinging motion of the rocker arm 2 into unidirectional rotational motion of the output shaft 3.10 of the transmission case 3. The mechanical energy generated by the unidirectional rotation of the output shaft 3.10 is then converted to electrical energy via the coupling 4, transmission 5, and flywheel 6, and finally by the generator 7, completing the entire process of converting wave energy into electrical energy.

[0022] For easier understanding, see Figures 1 to 2The rocker arm 2 includes two rocker rods 2.1 and three rocker cross braces 2.2 fixedly connected between the two rocker rods 2.1. The two rocker rods 2.1 are relatively fixed by the rocker cross braces 2.2. A float bolt 2.4 is provided at the left end of the rocker rod 2.1, which is fixedly connected to the float 1 via the float bolt 2.4. The right end of the rocker rod 2.1 is connected to a clamp 2.3, which tightly fits and is fixedly connected to the outer cylindrical surface of the inner gear ring 3.1. The rocker rod 2.1 and the clamp 2.3 are fixedly connected via a clamp bolt 2.5. In other words, the right end of the rocker rod 2.1 is fixedly connected to the inner gear ring 3.1 via the clamp 2.3 and the clamp bolt 2.5.

[0023] For easier understanding, see Figure 3 、 Figure 4 and Figures 8 to 10The transmission case 3 is a cylindrical housing with a defined cavity, consisting of an inner ring gear 3.1, a transparent cover end plate 3.11, and a blind cover end plate 3.6 fixed to each end of the inner ring gear 3.1. The transmission case 3 includes the ring gear shafting, output shafting, reversing shafting, and support system. The ring gear shafting comprises the bidirectionally rotatable cylindrical inner ring gear 3.1, a ring gear seal 3.5 fixed to the two ends of the inner ring gear 3.1, and a ring gear bearing 3.4 fixed inside the ring gear seal 3.5. The output shaft system includes an output shaft 3.10 partially located inside and partially outside the transmission case 3, a one-way clutch gear 3.3 located inside the transmission case 3 and fixed to the output shaft 3.10, a reversing gear 3.2 located inside the transmission case 3 and fixed to the output shaft 3.10, a transmission shaft bearing 3.8 for supporting the output shaft 3.10, a cover seal 3.12 fixed to the output shaft 3.10 in the output shaft hole 3.11.4 of the transmission case 3, and a spacer sleeve assembly 3.13 for axially positioning the shaft system components. The reversing shaft system includes a reversing shaft 3.9 located inside the transmission case 3, a one-way clutch gear 3.3 located inside the transmission case 3 and fixed to the reversing shaft 3.9, a reversing gear 3.2 located inside the transmission case 3 and fixed to the reversing shaft 3.9, a transmission shaft bearing 3.8 for supporting the reversing shaft 3.9, and a spacer sleeve assembly 3.13 for axially positioning the shaft system components. The support system includes the blind end plate 3.6, the transparent end plate 3.11, the jackscrew assembly 3.14, and the stud assembly 3.7. The blind end plate 3.6 includes the blind ring gear bearing seat 3.6.4, two blind bearing seats 3.6.5 located within the blind ring gear bearing seat 3.6.4, blind stud holes 3.6.3 located outside the diameter of the blind ring gear bearing seat 3.6.4, blind jackscrew holes 3.6.1 on the outside of the blind end plate 3.6 corresponding to the blind bearing seat 3.6.5, and blind foot holes 3.6.2 at the foot of the blind end plate 3.6. The transparent cover end plate 3.11 includes a transparent cover ring gear bearing seat 3.11.5, a blind hole bearing seat 3.11.6 and a through hole bearing seat 3.11.7 located inside the transparent cover ring gear bearing seat 3.11.5, an output shaft hole 3.11.4, a transparent cover stud bolt hole 3.11.3 located outside the diameter of the transparent cover ring gear bearing seat 3.11.5, a transparent cover top screw hole 3.11.1 on the outside of the transparent cover end plate 3.11 corresponding to the blind hole bearing seat 3.11.6, and a transparent cover base foot hole 3.11.2 at the base of the transparent cover end plate 3.11.The support system of the transmission case 3 includes a transparent cover end plate 3.11 and a blind cover end plate 3.6. The ring gear shaft system, output shaft system and reversing shaft system are clamped and installed between the transparent cover end plate 3.11 and the blind cover end plate 3.6. Among them, the transparent cover ring gear bearing seat 3.11.5 and the blind cover ring gear bearing seat 3.6.4 supporting the ring gear shaft system, the blind hole bearing seat 3.11.6 and the blind cover bearing seat 3.6.5 supporting the reversing shaft system, the through hole bearing seat 3.11.7 and the blind cover bearing seat 3.6.5 supporting the output shaft system, and the stud bolt holes of the two end plates are all coaxial with each other. The one-way clutch gear 3.3 of the output shaft system and the reversing shaft system of the transmission case 3 are meshed with the internal teeth of the inner ring gear 3.1, and the reversing gear 3.2 on the output shaft system and the reversing shaft system are externally meshed with each other.

[0024] Specifically, the transmission case 3 includes a transparent cover end plate 3.11, a sealed cover end plate 3.6, and a cylindrical inner ring gear 3.1. The transparent cover end plate 3.11 and the sealed cover end plate 3.6 are respectively located on the left and right sides of the inner ring gear 3.1. The inner ring gear 3.1 and the transparent cover end plate 3.11 and the sealed cover end plate 3.6 connected to the inner ring gear 3.1 on both sides are enclosed together to form a box-like enclosed space through the ring gear bearing 3.4 and the ring gear seal 3.5 at both ends. The lower parts of the transparent cover end plate 3.11 and the blind cover end plate 3.6 are respectively provided with transparent cover foot holes 3.11.2 and blind cover foot holes 3.6.2. The frame bolt group 2.1.4 respectively penetrates the transparent cover foot holes 3.11.2, the box frame connecting holes 8.1 and the frame bottom plate 2.1.3, the blind cover foot holes 3.6.2, the box frame connecting holes 8.1 and the frame bottom plate 2.1.3 from top to bottom, thereby achieving relative fixation between the transparent cover end plate 3.11 and the fixing frame 8 and the frame 2.1, and the blind cover end plate 3.6 and the fixing frame 8 and the frame 2.1. The cover end plate 3.11 and the cover end plate 3.6 are provided with corresponding cover stud holes 3.11.3 and cover stud holes 3.6.3. Four sets of stud assemblies 3.7 are inserted through the outer side of the inner ring gear 3.1, penetrating the cover stud holes 3.11.3 and cover stud holes 3.6.3, respectively, on the cover end plate 3.11 and the cover end plate 3.6, respectively, to secure the cover end plate 3.11 and the cover end plate 3.6 relative to each other. One end of the inner ring gear 3.1 is rotationally connected to the cover end plate 3.11 via a ring gear bearing 3.4, while the other end of the inner ring gear 3.1 is rotationally connected to the cover end plate 3.6 via the ring gear bearing 3.4. A ring gear seal 3.5 is installed at the connection between the inner ring gear 3.1 and the ring gear bearing 3.4. This seal prevents seawater or moisture from entering the transmission case 3 through the gap between the inner ring gear 3.1 and the transparent cover end plate 3.11 or the sealed cover end plate 3.6. This prevents seawater or moisture from corroding the mechanical transmission components within the transmission case 3, thereby increasing their service life. The inner cylindrical surface of the inner ring gear 3.1 is provided with internal teeth in the middle. These teeth engage two identical one-way clutch gears 3.3. One of the one-way clutch gears 3.3 is fixed to the output shaft 3.10, and the other is fixed to the reversing shaft 3.9. One end of the output shaft 3.10 is rotatably connected to the transparent cover end plate 3.11 via a transmission shaft bearing 3.8. It then extends through an output shaft hole 3.11.4 in the transparent cover end plate 3.11 and connects to the coupling 4. The other end of the output shaft 3.10 is rotatably connected to the blind cover end plate 3.6 via a transmission shaft bearing 3.8. The two ends of the reversing shaft 3.9 are rotatably connected to the transparent cover end plate 3.11 and the blind cover end plate 3.6, respectively, via transmission shaft bearings 3.8.On one side of the cover end plate 3.11, a cover seal 3.12 is provided at the connection between the output shaft 3.10 and the transmission shaft bearing 3.8. This seal prevents seawater or water vapor from entering the transmission case 3 through the gap between the output shaft 3.10 and the output shaft hole 3.11.4, thereby preventing seawater or water vapor from corroding and damaging the mechanical transmission components within the transmission case 3, thereby increasing their service life. Furthermore, a lubrication system can be provided within the transmission case, depending on the temperature of the sea area where the wave energy generator is located. Either grease or oil lubrication can be used to improve mechanical transmission efficiency. Two identical reversing gears 3.2 are also provided within the inner ring gear 3.1. The two reversing gears 3.2 are externally meshed and connected to each other. The two reversing gears 3.2 are fixedly mounted on the output shaft 3.10 and the reversing shaft 3.9, respectively. Two axially positioned spacer sleeves 3.13 are fixedly mounted on the output shaft 3.10 and the reversing shaft 3.9, respectively. The two spacer sleeves 3.13 are located between the one-way clutch gear 3.3 and the transmission shaft bearing 3.8, and between the reversing gear 3.2 and the transmission shaft bearing 3.8, respectively, to provide axial positioning for the parts.

[0025] The installation method of two identical one-way clutch gears 3.3, which are respectively engaged with the internal teeth of the internal gear ring 3.1, is as follows: Step 1: Define the driving direction of the one-way clutch gear 3.3 connected to the output shaft 3.10 as the forward rotation direction, and ensure that only the forward rotation of the one-way clutch gear 3.3 can drive the output shaft 3.10 to rotate forward, otherwise it will idle and slip.

[0026] Step 2: Set the driving direction of the one-way clutch gear 3.3 connected to the reversing shaft 3.9 to the reverse rotation direction, and ensure that only the reverse rotation of the one-way clutch gear 3.3 can drive the reversing shaft 3.9 to rotate in the reverse direction, otherwise it will idle and slip.

[0027] Step 3: Install the two one-way clutch gears 3.3 on the output shaft 3.10 and the reversing shaft 3.9 respectively in opposite driving directions.

[0028] Specifically, the driving direction of the one-way clutch gear 3.3 connected to the output shaft 3.10 is forward (clockwise). When the one-way clutch gear 3.3 rotates forward, it will drive the output shaft 3.10 to rotate forward. When the one-way clutch gear 3.3 rotates reversely, the one-way clutch gear 3.3 will slip and cannot transmit power to the output shaft 3.10, that is, it cannot drive the output shaft 3.10 to rotate; the driving direction of the one-way clutch gear 3.3 connected to the reversing shaft 3.9 is reverse (counterclockwise). When the one-way clutch gear 3.3 rotates reversely, it will drive the reversing shaft 3.9 to rotate reversely. When the one-way clutch gear 3.3 rotates forward, the one-way clutch gear 3.3 will slip and cannot transmit power to the reversing shaft 3.9, that is, it cannot drive the reversing shaft 3.9 to rotate.

[0029] For easier understanding, see Figures 5 to 7 Annular transparent cover gear ring bearing seats 3.11.5 and 3.6.4 are protruded horizontally from the transparent cover end plate 3.11 and the blind cover end plate 3.6, respectively. The transparent cover gear ring bearing seat 3.11.5 on the transparent cover end plate 3.11 and the blind cover gear ring bearing seat 3.6.4 on the blind cover end plate 3.6 are coaxial and have the same outer diameter.

The inner wall ends of the inner ring gear 3.1 are rotatably connected to the transparent cover gear ring bearing seats 3.11.5 and the blind cover gear ring bearing seats 3.6.4, respectively, via the gear ring bearings 3.4. That is, the inner wall ends of the inner ring gear 3.1 are rotatably connected to the transparent cover end plate 3.11 and the blind cover end plate 3.6, respectively, via the gear ring bearings 3.4.

[0030] For easier understanding, please refer to Figures 5 to 7An annular blind hole bearing seat 3.11.6 and an annular through hole bearing seat 3.11.7 are horizontally protruded side by side on the transparent cover end plate 3.11. The output shaft hole 3.11.4 on the transparent cover end plate 3.11 is located in the center of the through hole bearing seat 3.11.7. Both the blind hole bearing seat 3.11.6 and the through hole bearing seat 3.11.7 are located in the central annular area of the transparent cover ring gear bearing seat 3.11.5. Two annular blind cover bearing seats 3.6.5 are horizontally protruded side by side on the blind cover end plate 3.6. Both blind cover bearing seats 3.6.5 are located in the central annular area of the blind cover ring gear bearing seat 3.6.4.

In other words, the two ends of the output shaft 3.10 are rotationally connected to the through-cover end plate 3.11 and the blind cover end plate 3.6 inside the inner ring gear 3.1 through the transmission shaft bearing 3.8.

[0031] For easier understanding, see Figures 3 and 4 A pair of jackscrew assemblies 3.14 are installed on the transparent cover end plate 3.11, and two pairs of jackscrew assemblies 3.14 are installed on the blind cover end plate 3.6. These jackscrew assemblies 3.14 are used for loading and unloading and maintaining bearings in blind holes. These jackscrew assemblies 3.14 include a jackscrew 3.14.1, a lock nut 3.14.2 that slidably fits over the jackscrew 3.14.1, and a sealing gasket 3.14.3. Corresponding jackscrew holes 3.6.1 for the blind cover and 3.11.1 for the transparent cover end plate 3.11 and the blind cover end plate 3.6 are respectively provided.

[0032] The installation and use of the top screw assembly 3.14 are as follows: Step 1: Install the reversing gear 3.2, one-way clutch gear 3.3, ring gear bearing 3.4, ring gear seal 3.5, cover end plate 3.6, stud bolt assembly 3.7, transmission shaft bearing 3.8, reversing shaft 3.9, output shaft 3.10, cover end plate 3.11, cover seal 3.12 and spacer assembly 3.13 according to the process requirements.

[0033] Step 2: Screw the top screw 3.14.1 with the locking nut 3.14.2 and the sealing gasket 3.14.3 into the blind cover top screw screw hole 3.6.1 of the blind cover end plate 3.6 and the transparent cover top screw screw hole 3.11.1 of the transparent cover end plate 3.11 respectively. Control the distance between the end of the rod of the top screw 3.14.1 and the outer end surface of the corresponding transmission shaft bearing 3.8 within the range of 1.5 to 2 mm. Tighten the locking nut 3.14.2 to press and lock the sealing gasket 3.14.3 to the corresponding top screw 3.14.1 screw hole.

[0034] Step 3: Each transmission shaft bearing 3.8 is provided with a pair of top screw assemblies 3.14 at the outer end. When adjusting or removing the transmission shaft bearing 3.8, first loosen the locking nut 3.14.2, remove the top screw 3.14.1 with the locking nut 3.14.2 and the sealing gasket 3.14.3, remove the locking nut 3.14.2 and the sealing gasket 3.14.3 from the top screw 3.14.1, screw the top screw 3.14.1 into the blind cover top screw screw hole 3.6.1 or the transparent cover top screw screw hole 3.11.1 again, and the two top screws 3.14.1 in a pair of top screw assemblies 3.14 should be screwed in synchronously and slowly until the corresponding transmission shaft bearing 3.8 is safely ejected and removed.

[0035] Step 4: When reinstalling the transmission box 3, repeat the first and second steps.

[0036] Specifically, each blind hole of the transparent cover end plate 3.11 and the blind cover end plate 3.6 in the transmission box 3 (the rotation connection between the reversing shaft 3.9 and the blind hole bearing seat 3.11.6, the rotation connection between the reversing shaft 3.9 and the blind cover bearing seat 3.6.5, and the rotation connection between the output shaft 3.10 and the blind cover bearing seat 3.6.5) is equipped with a pair of top screw assemblies 3.14. After the output shaft 3.10, the reversing shaft 3.9 and the transmission shaft bearing 3.8 at their corresponding blind hole ends are installed and positioned, the top screws 3.14.1 with the sealing gasket 3.14.3 and the locking nut 3.14.2 are installed in sequence on the corresponding top screw holes of the transparent cover end plate 3.11 and the blind cover end plate 3.6. A gap of 1.5mm to 2mm is maintained between the end of the rod of each top screw 3.14.1 and the end face of the installed and positioned transmission shaft bearing 3.8. While keeping the top screw 3.14.1 from rotating, the top screws 3.14.1 are locked by tightening. The nut 3.14.2 presses and locks the sealing gasket 3.14.3 on the corresponding jackscrew hole, thus completing the installation and positioning of the jackscrew assembly 3.14; when it is necessary to disassemble the transmission shaft bearing 3.8, first completely remove the jackscrew assembly 3.14, remove the sealing gasket 3.14.3 and the locking nut 3.14.2, and then screw only the jackscrew 3.14.1 back into the original jackscrew hole. The two jackscrews 3.14.1 in each blind hole should be tightened and screwed in synchronously and evenly until the corresponding transmission shaft bearing 3.8 is safely ejected.

[0037] The overall installation method of the rocker arm oscillation float type wave energy power generation device is as follows: Step 1: Install the transmission case 3, transmission 5, and generator 7 on the fixed frame 8. At the same time, install and position the coupling 4 and flywheel 6 according to the process requirements. Then fix one end of the rocker arm 2 to the inner gear ring 3.1 of the transmission case 3, and then fix the other end of the rocker arm 2 to the float 1. Step 2: The wave energy power generation device is integrally mounted and positioned on an offshore floating platform or other offshore power generation structure through the floating frame connection holes 8.2 on the fixing frame 8.

[0038] Furthermore, the coaxiality between the output shaft 3.10 and the low-speed shaft of the transmission 5 is less than 0.3mm, and the coaxiality between the main shaft of the generator 7 and the high-speed shaft of the transmission 5 is less than 0.08mm. During installation, after the transmission case 3, coupling 4, transmission 5, flywheel 6, and generator 7 are all securely in place, a rotation inspection of the flywheel 6 is required. The radial runout and end face runout of the flywheel 6 during rotation must not exceed tolerances and must meet relevant technical requirements.

[0039] Furthermore, the fixing frame 8 on which the transmission box 3, the transmission 5 and the generator 7 are fixedly mounted can be installed on a platform at a certain height from the sea level. The above platform can be a platform floating on the sea surface or a platform fixed on the sea surface.

[0040] When installing transmission case 3, pay special attention to installing the one-way clutch gear 3.3 connected to output shaft 3.10 in the forward direction of rotation of output shaft 3.10, and installing the one-way clutch gear 3.3 connected to reversing shaft 3.9 in the reverse direction of rotation of reversing shaft 3.9. Both one-way clutch gears 3.3 simultaneously mesh with the internal teeth of the internal gear ring 3.1. The technical requirements for the gear transmission installation should meet the gear pair accuracy grade ISO 8 or above, with a normal backlash of 0.08 to 0.13mm. Lubrication should be carried out with a seawater-resistant grease (such as a composite calcium sulfonate grease or a polyurea-based grease).

[0041] Working principle of the present invention: As the float 1 rises and falls with the waves, it drives the rocker arm 2.1 to rotate around the rotation axis of the inner gear ring 3.1 in a bidirectional rotational motion that alternates between forward and reverse rotation. Specifically, when the float 1 rises, the rocker arm 2.1 rotates forward; when the float 1 sinks, the rocker arm 2.1 rotates reversely. Because the rocker arm 2.1 is tightly fitted and fixed to the outer cylindrical surface of the inner gear ring 3.1 via a clamp, the swing of the rocker arm 2.1 drives the inner gear ring 3.1 to rotate around its own axis in a bidirectional rotational motion that alternates between forward and reverse rotation. Specifically, when the rocker arm 2.1 rotates forward, the inner gear ring 3.1 rotates forward, and when the rocker arm 2.1 rotates reversely, the inner gear ring 3.1 rotates reversely. Because the two one-way clutch gears 3.3 mesh with the internal teeth of the ring gear 3.1, the bidirectional rotation of the ring gear 3.1 drives the one-way clutch gears 3.3 to rotate in a bidirectional manner, alternating between forward and reverse rotation, about their respective axes. Specifically, when the ring gear 3.1 rotates forward, it drives the two one-way clutch gears 3.3 to rotate forward simultaneously; when the ring gear 3.1 rotates reversely, it drives the two one-way clutch gears 3.3 to rotate reversely simultaneously. When the one-way clutch gears 3.3 connected to the output shaft 3.10 rotate forward, they drive the output shaft 3.10 to rotate forward. Because the output shaft 3.10 passes through the coupling 4, the transmission 5, the flywheel 6, and then connects to the generator 7 on the outside of the ring gear 3.1, the forward rotational force of the one-way clutch gears 3.3 connected to the output shaft 3.10 is transmitted to the output shaft 3.10, driving the output shaft 3.10 to rotate forward, thereby completing the process of converting the mechanical energy generated by the float 1 during the upward stroke into electrical energy. When the one-way clutch gear 3.3 connected to the reversing shaft 3.9 rotates in the reverse direction, it will drive the reversing shaft 3.9 to rotate in the reverse direction. Since a reversing gear 3.2 is fixedly sleeved on the outer sides of the output shaft 3.10 and the reversing shaft 3.9, the reverse rotation of the reversing shaft 3.9 will drive the reversing gear 3.2 connected to the reversing shaft 3.9 to rotate in the reverse direction. Since the two reversing gears 3.2 are meshed and connected, the reverse rotation of the reversing gear 3.2 connected to the reversing shaft 3.9 will drive the reversing gear 3.2 connected to the output shaft 3.10 to rotate forward. The reversing gear 3.2 connected to the output shaft 3.10 is fixedly sleeved on the outside of the output shaft 3.10. Therefore, the forward rotation of the reversing gear 3.2 connected to the output shaft 3.10 will drive the output shaft 3.10 to rotate forward. Since the output shaft 3.10 passes through the coupling 4, the transmission 5, the flywheel 6 in sequence outside the inner gear ring 3.1 and is connected to the generator 7 to generate electricity, the reverse power of the one-way clutch gear 3.3 connected to the reversing shaft 3.9 is transmitted to the output shaft 3.10, driving the output shaft 3.10 to rotate forward to generate electricity, thereby completing the process of converting the mechanical energy generated by the float 1 during the downward stroke into electrical energy.
