Description

Technical Field

[0001] The present invention relates to the technical field of wave energy power generation, and in particular to a double-rocker rocker arm type oscillating float 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:

[0004] 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.

[0005] 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.

[0006] 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.

[0007] 4. Since the height of the offshore platform is relatively high above the still sea level, a large angle is formed between the theoretical rocker line (the line connecting the center of mass of the float and the center of rocker swing) and the sea level. This angle greatly reduces the efficiency of the float in capturing wave energy under wave excitation, thereby affecting the power generation efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0048] In order to enable those 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.

[0049] For easier understanding, see Figure 1 、 Figure 2 and Figure 14This embodiment provides a double-rocker rocker arm oscillating float wave energy power generation device, including a float 1, a double-rocker 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 passing through the transmission fixing holes 8.3 are used 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. The fixed frame 8 is provided with four vertical floating frame connection holes 8.2. Through the floating frame connection holes 8.2, the fixed frame 8 can be installed on an offshore floating frame or on a dedicated truss fixed at sea. 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 head-on side and descends to the sea surface on the wave's tail-off side. In other words, when excited by the wave, float 1 absorbs wave energy, generating an up-and-down motion that follows the wave. Float 1 is connected to the left end of a double-arm rocker 2. The right end of the double-arm rocker 2 is connected to a transmission 3, which is connected to a transmission 5 via a 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. The output shaft 3.10 of the transmission 3 is connected to the low-speed shaft of the transmission 5 via a coupling 4. The transmission 5 steps up the rotational speed of the output shaft 3.10, increasing the speed to the required power generation speed. This speed is then transmitted via the high-speed shaft of the transmission 5 to the main shaft of the 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 5.2 of the transmission 5 and the main shaft of the generator 7. 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 variable speed power generation module can operate normally to generate electricity during the entire wave energy capture process.

[0050] As the buoy 1 rises and falls with the waves, the double-arm 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 the bidirectional rotational motion transmitted by the double-arm rocker arm 2 into unidirectional rotational motion. This converts the bidirectional swinging motion of the double-arm 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 into electrical energy through 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.

[0051] For easier understanding, see Figures 2 to 5The double rocker arm 2 includes a frame 2.1, a long rocker 2.2, a connecting rod 2.3, a short rocker 2.4, a clamp 2.5, and a hinge shaft 2.6. The left end of the long rocker 2.2 is fixedly connected to the float 1, and the right end of the long rocker 2.2 is fixedly connected to a hinge shaft 2.6 via a locking bolt assembly 2.7. The right end of the long rocker 2.2 is rotatably connected to the frame 2.1 via the hinge shaft 2.6. The frame 2.1 is fixedly connected to the bottom of the fixed frame 8. The upper and lower ends of the connecting rod 2.3 are fixedly connected to a hinge shaft 2.6 via a locking bolt assembly 2.7. The lower end of the connecting rod 2.3 is rotationally connected to the middle part of the long rocker arm 2.2 via the hinge shaft 2.6. The upper end of the connecting rod 2.3 is rotationally connected to the left end of the short rocker arm 2.4 via the hinge shaft 2.6. The right end of the short rocker arm 2.4 is connected to a clamp 2.5. The clamp 2.5 fits tightly against the outer cylindrical surface of the inner gear ring 3.1 and is locked. The right end of the short rocker arm 2.4 is fixedly connected to the inner gear ring 3.1 via the clamp 2.5. In the initial state, the long rocker arm 2.2 and the short rocker arm 2.4 are both roughly parallel to the static sea level, and the connecting rod 2.3 is roughly perpendicular to the rocker arm and the short rocker arm 2.4 respectively. The distance between the upper and lower hinge shafts 2.6 at the connecting rod 2.3 is determined according to the distance between the fixing frame 8 and the static sea level (e.g. Figure 2 (As shown in the middle h height), the hinge axis 2.6 between the long rocker 2.2 and the frame 2.1 is close to the still sea surface, so that the angle between the theoretical rocker arm force line (the line connecting the center of mass of the float and the swing center of the rocker directly fixing the float) and the still sea surface approaches zero degrees, effectively increasing the torque of the long rocker 2.2, that is, increasing the swing amplitude of the long rocker 2.2, ensuring that the efficiency of the float 1 in capturing wave energy under wave excitation is at an optimal state.

[0052] For easier understanding, please refer to Figures 2 to 5The frame 2.1 includes a frame rod 2.1.1, a rib plate 2.1.2, a frame base plate 2.1.3, and a frame bolt assembly 2.1.4. The lower end of the frame rod 2.1.4 is pivotally connected to the right end of the long rocker 2.2, and the upper end of the frame rod 2.1.4 is fixedly connected to the frame base plate 2.1.3. The triangular rib plate 2.1.2 is fixedly connected to both the frame rod 2.1.4 and the frame base plate 2.1.3. The rib plate 2.1.2 makes the connection between the frame rod 2.1.4 and the frame base plate 2.1.3 more stable and secure. The frame base plate 2.1.3 is fixedly connected to the fixing frame 8 via the frame bolt assembly 2.1.4. The hinge shaft 2.6 is fitted with bearings 2.6.5 at its pivoting connections with the long rocker 2.2 and the short rocker 2.4. Seals 2.6.4 are located on either side of the bearing 2.6.5's axial axis. These seals prevent seawater or moisture from entering the bearing 2.6.5 through the pivoting gap, thereby preventing corrosion damage to the bearing 2.6.5 and increasing its service life. The bearing 2.6.5 is pivotally connected to a bearing sleeve 2.6.3 on its outer circumferential side. The bearing sleeve 2.6.3 is fixedly mounted within the long rocker 2.2 and the short rocker 2.4. Specifically, the right end of the long rocker 2.2 is pivotally connected to the lower end of the frame rod 2.1.4 via bearing 2.6.5. The middle of the long rocker 2.2 is pivotally connected to the lower end of the connecting rod 2.3 via bearing 2.6.5. The left end of the short rocker 2.4 is pivotally connected to the upper end of the connecting rod 2.3 via bearing 2.6.5. The articulated shaft 2.6 is mounted on the long rocker 2.2 and the short rocker 2.4 through the bearing cover 2.6.1 and the corresponding cover bolts 2.6.2.

[0053] For easier understanding, see Figures 6 and 7 and Figures 11 to 13The transmission case 3 includes a ring gear shaft system, an output shaft system, a reversing shaft system and a support system. The ring gear shaft system includes a bidirectionally rotatable inner ring gear 3.1, a ring gear bearing 3.4, and a ring gear seal 3.5. The output shaft system includes an output shaft 3.10, a one-way clutch gear 3.3, a reversing gear 3.2, a transmission shaft bearing 3.8, a transparent cover seal 3.12, and a spacer set 3.13. The reversing shaft system includes a reversing shaft 3.9, a one-way clutch gear 3.3, a reversing gear 3.2, a transmission shaft bearing 3.8, and a spacer set 3.13. The support system includes a blind cover end plate 3.6, a transparent cover end plate 3.11, a top screw assembly 3.14, and a stud bolt assembly 3.7. The blind cover end plate 3.6 includes a blind cover ring gear bearing seat 3.6.4 and two blind cover bearing seats 3.6 located inside the blind cover ring gear bearing seat 3.6.4. .5, the blind cover stud bolt hole 3.6.3 located outside the diameter of the blind cover gear ring bearing seat 3.6.4, the top screw hole 3.6.1 on the outside of the blind cover end plate 3.6 corresponding to the blind cover bearing seat 3.6.5, and the foot hole 3.6.2 at the bottom foot of the blind cover end plate 3.6. The transparent cover end plate 3.11 includes a transparent cover gear ring 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 gear ring bearing seat 3.11.5, the output shaft hole 3.11.4, the transparent cover stud bolt hole 3.11.3 located outside the diameter of the transparent cover gear ring bearing seat 3.11.5, the 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 the foot hole 3.11.2 at the bottom foot of the transparent cover end plate 3.11.

[0054] 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.

[0055] 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:

[0056] 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. 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.

[0057] 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, ensuring 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;

[0058] 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.

[0059] 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.

Specifically, the two ends of the reversing shaft 3.9 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 via the drive shaft bearings 3.8. One end of the output shaft 3.10 is rotationally connected to another blind cover bearing seat 3.6.5 via a transmission shaft bearing 3.8.

[0062] For easier understanding, see Figures 6 and 7 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.

[0063] The installation and use of the top screw assembly 3.14 are as follows:

[0064] 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.

[0065] Step 2: Screw the top screw 3.14.1 with the lock nut 3.14.2 and the sealing gasket 3.14.3 into the cover top screw screw hole 3.6.1 of the 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. Keep 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 lock nut 3.14.2 to press the sealing gasket 3.14.3 into the corresponding screw hole of the top screw 3.14.1.

[0066] Step 3: Each transmission shaft bearing 3.8 is provided with a pair of jackscrew 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 jackscrew 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 jackscrew 3.14.1, and screw the jackscrew 3.14.1 into the blind cover jackscrew hole 3.6.1 or the transparent cover jackscrew hole 3.11.1 again. The two jackscrews 3.14.1 in the pair of jackscrew assemblies 3.14 should be screwed in synchronously and slowly until the corresponding transmission shaft bearing 3.8 is safely ejected and removed.

[0067] Step 4: When reinstalling the transmission box 3, repeat the first and second steps.

[0068] The installation method of the double rocker rocker oscillating float wave energy power generation device is as follows:

[0069] Step 1: Complete the assembly of the transmission case 3 according to the process requirements;

[0070] Step 2: Complete the assembly of the double rocker arm 2 according to the process requirements;

[0071] Step 3: Use the frame bolt group 2.1.4 to install and position the frame 2.1, the fixing frame 8 and the transmission box 3 according to the process requirements, and use the clamp bolt group 2.8 to install the right end of the double rocker arm 2 and the transmission box 3 according to the process requirements;

[0072] Step 4: Install the coupling 4, transmission 5, flywheel 6 and generator 7 on the fixed frame 8 according to the sequence and process requirements;

[0073] Step 5: Install the float 1 on the left end of the double rocker arm 2 according to the process requirements.

[0074] 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.

[0075] 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.

[0076] 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).

[0077] Working principle of the present invention:

[0078] When the float 1 moves up and down with the waves, it will drive the long rocker 2.2 to perform a bidirectional rotational motion of alternating forward and reverse rotation around the hinge of the frame rod 2.1.1; specifically, when the float 1 rises, the long rocker 2.2 rotates forward; when the float 1 sinks, the long rocker 2.2 rotates reversely. Since the middle part of the long rocker arm 2.2 is rotatably connected to the lower end of the connecting rod 2.3, and the upper end of the connecting rod 2.3 is rotatably connected to the left end of the short rocker arm 2.4, and the right end of the short rocker arm 2.4 is tightly fitted and fixedly connected to the outer cylindrical surface of the inner gear ring 3.1 through the clamp 2.5, the swing of the long rocker arm 2.2 will drive the short rocker arm 2.4 to swing completely synchronously with the long rocker arm 2.2, and the swing of the short rocker arm 2.4 will drive the inner gear ring 3.1 to perform a bidirectional rotational motion around its own axis, alternating between forward and reverse rotation; specifically, when the long rocker arm 2.2 rotates forward, the short rocker arm 2.4 rotates forward and the inner gear ring 3.1 rotates forward; when the long rocker arm 2.2 rotates reversely, the short rocker arm 2.4 rotates reversely and 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 both one-way clutch gears 3.3 to rotate forward simultaneously; when the ring gear 3.1 rotates reversely, it drives both one-way clutch gears 3.3 to rotate reversely simultaneously. When the one-way clutch gears 3.3 fixed to the output shaft 3.10 rotate forward, they drive the output shaft 3.10 to rotate forward, causing the one-way clutch gears 3.3 fixed to the reversing shaft 3.9 to rotate idly. 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, generating electricity. This completes the process of converting the mechanical energy generated by the float 1 during its upward stroke into electrical energy. When the one-way clutch gear 3.3 fixed on the reversing shaft 3.9 rotates in the reverse direction, it will drive the reversing shaft 3.9 to rotate in the reverse direction, and the one-way clutch gear 3.3 fixed on the output shaft 3.10 will rotate idly. Since a reversing gear 3.2 is fixedly sleeved on the outer side 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 externally meshed and connected, they are connected to the reversing shaft 3.9. 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. Since the output shaft 3.10 passes through the coupling 4, the transmission 5, the flywheel 6 on the outside of the inner gear ring 3.1 in sequence 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.

[0079] Although the present application has been described with reference to the preferred embodiments thereof, it is to be understood that the application is not limited to the details described herein and that various modifications and changes can be made without departing from the spirit and scope of the present application.
