Description

Technical Field

[0001] The present invention relates to the technical field of wave energy power generation, and in particular to a wave energy power generation device with two rockers and two floats in series 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 application CN118934413A discloses an offshore wave energy power generation device, comprising an offshore platform, an energy conversion mechanism, comprising a generator disposed on the offshore platform, a gear set disposed on the generator, and a drive shaft disposed on the gear set; a rotating mechanism, comprising a housing disposed on the offshore platform, and a rotating wheel disposed within the housing, wherein a coil spring is disposed within 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 force and energy, allowing the generator to rotate for a longer period of time. 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.

[0008] 5. In the above-mentioned offshore wave energy power generation device, one float can only drive one set of variable speed power generation modules independently, and it is not possible to realize that multiple floats drive one set of variable speed power generation modules. Its wave energy capture and overall power generation efficiency are low. Summary of the Invention

[0021] Second, the typical double-rocker mechanism in mechanics is applied to the rocker-type wave energy power generation device, which solves the problem of the rocker swing center being too high, and makes the theoretical rocker line (the line connecting the center of mass of the float and the rocker swing center to which the float is directly fixed) basically parallel to the still sea level, so that the float can capture wave energy to the maximum extent.

[0022] Third, the transmission box adopts a one-cylinder, two-shaft, four-gear internal meshing structural design with a differential overrunning function; the power synthesis of the two floats is superimposed on a set of variable-speed power generation modules, realizing the double-stroke work of the rocker arm swinging up and down. Compared with the open external meshing transmission box, the transmission efficiency is increased from 70% to more than 90%. Combined with the flywheel energy storage balancing effect, the generator speed can reach within the national standard allowable value range.

[0023] Fourth, the generator boasts a compact structure, high transmission torque, excellent overall rigidity, and seals with lubrication. Combined with specialized installation methods, it is simple to manufacture, operate, and maintain. This design is well-suited for small and medium-sized wave power generation installations, particularly those located on platforms where the center of the boom swing is high above the still sea level. This provides an important foundation for the construction of wave power generation installations on ships, vessels, and higher platforms. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] 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.

[0044] For easier understanding, see Figure 1 、 Figure 2 as well as Figure 15This embodiment provides a series double rocker arm double float wave energy power generation device and its installation method, including a set of conversion modules and a set of variable speed power generation components. The conversion module includes two floats 1, two double rocker arms 2, and two transmission boxes 3. The variable speed power generation component includes 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 fixing holes 8.3 to achieve relative fixation between the transmission 5 and the fixed frame 8, and bolts are passed through six generator mounting holes 8.4 to achieve relative fixation between the generator 7 and the fixed frame 8. A plurality of 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 truss fixed on the sea. The float 1's own weight is less than the buoyancy generated by its volume, so it floats on the sea surface. When a wave passes through the area where the float 1 is placed, the float 1 can follow the wave's movement. Specifically, the 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. That is, when the float 1 is excited by the wave, it absorbs the wave energy and follows the wave's ups and downs. Each float 1 is connected to one end of a corresponding double-rocker arm 2, the other end of which is connected to a corresponding transmission box 3. The two transmission boxes 3 in the conversion module are arranged adjacent to each other and are connected in series via an output shaft 3.10 for transmission. The output shaft 3.10 is connected to the low-speed shaft of the transmission 5 via a coupling 4 for power generation. Transmission 5 is a speed-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 case 3 is connected to the low-speed shaft of transmission 5 via a coupling 4. Transmission 5 is capable of increasing the speed of the rotation of output shaft 3.10, so that the speed of output shaft 3.10 reaches the speed required for power generation. This speed is then transmitted to the main shaft of generator 7 via the high-speed shaft of transmission 5, thereby generating electricity. A flywheel 6 is installed between transmission 5 and generator 7. Its center hole is connected to both the high-speed shaft of transmission 5 and the main shaft of generator 7. Serving as an energy storage element, flywheel 6 balances the speed of the main shaft of generator 7 during the alternating up and down swinging of the double rocker arm 2. This further ensures that the main shaft rotational speed of generator 7 falls within the permissible range of the speed nonuniformity coefficient, ensuring that the variable-speed power generation module operates normally throughout the entire wave energy capture process.

[0045] As the float 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 box 3, alternating between forward and reverse rotation (clockwise and counterclockwise). The transmission box 3 converts the bidirectional rotational motion transmitted by the double-arm rocker arm 2 into unidirectional rotational motion, converting the up-and-down bidirectional power motion of the double-arm rocker arm 2 into unidirectional rotational power motion of the output shaft 3.10 of the transmission box 3. Because the two floats 1 are located in different positions, the amplitude, speed, and phase angle of the up-and-down swing of the corresponding double-arm rocker arms 2 are inconsistent, resulting in different output power from the two floats 1. Furthermore, since the two transmission boxes 3 are interconnected via an output shaft 3.10, the transmission box 3 with the greater power of the two transmission boxes transmits power to the output shaft 3.10.

[0046] For easier understanding, see Figures 2 to 6 The 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 assembly 2.5, a hinge shaft 2.6, and a locking bolt assembly 2.7. 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 rotationally 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 rotatably connected to the middle portion of the long rocker arm 2.2 via the hinge shaft 2.6. The upper end of the connecting rod 2.3 is rotatably 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 assembly 2.5. The clamp assembly 2.5 fits tightly against the outer cylindrical surface of the inner gear ring 3.1 and is locked in place. The clamp assembly 2.5 secures the right end of the short rocker arm 2.4 to the inner gear ring 3.1. The distance between the upper and lower hinge shafts 2.6 at the connecting rod 2.3 is determined by the distance between the fixing frame 8 and the still sea surface (e.g. Figure 2 (As shown in the height of h in the middle), 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 and ensuring that the efficiency of the float 1 in capturing wave energy under wave excitation is at an optimal state.

[0047] For easier understanding, please refer to Figures 2 to 6The 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 the hinge centers of 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 gap between the rotating connections, thereby preventing corrosion damage to the bearing 2.6.5 and increasing its service life. Bearing sleeves 2.6.3 are mounted on the outer circumference of the bearing 2.6.5. These sleeves are fixedly mounted inside the long rocker 2.2 and short rocker 2.4, respectively. 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 hinge shaft 2.6 is mounted on the long rocker 2.2 and the short rocker 2.4, respectively, via a bearing cover plate 2.6.1 and corresponding cover plate bolts 2.6.2. The clamp assembly 2.5 comprises a clamp ring 2.5.1, a clamp bolt assembly 2.5.2, and a clamp reinforcement plate 2.5.3.

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, through the frame bolt group 2.1.4 respectively from top to bottom through 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, to achieve 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, thereby achieving fixed installation of the outer transmission box 3 and the inner transmission box 3 on the fixing frame 8. The cover end plate 3.11 and the blind end plate 3.6 are provided with corresponding cover stud holes 3.11.3 and blind end stud holes 3.6.3. Four sets of stud assemblies 3.7 penetrate the cover stud holes 3.11.3 and blind end stud holes 3.6.3 on the outer side of the inner ring gear 3.1, respectively, to achieve relative fixation between the two cover end plates 3.11, or between one cover end plate 3.11 and one blind end plate 3.6. Inside the outer transmission case 3, 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, and the other end of the inner ring gear 3.1 is rotationally connected to the blind end plate 3.6 via a ring gear bearing 3.4. Inside the inner transmission case 3, both ends of the inner ring gear 3.1 are rotationally connected to the cover end plate 3.11 via the ring gear bearing 3.4. A gear ring seal 3.5 is provided at the connection between the inner gear ring 3.1 and the gear ring bearing 3.4. The gear ring seal 3.5 can prevent seawater or water vapor from entering the transmission case 3 through the connection gap between the inner gear ring 3.1 and the transparent cover end plate 3.11 or the blind cover end plate 3.6, thereby preventing seawater or water vapor from corroding and damaging the mechanical transmission components inside the transmission case 3, thereby increasing their service life.Internal teeth are located in the middle of the inner cylindrical surface of the ring gear 3.1. These teeth mesh with two identical one-way clutch gears 3.3. One of these one-way clutch gears 3.3 is fixed to the output shaft 3.10, while the other is fixed to the reversing shaft 3.9. Inside the outer transmission case 3, one end of the output shaft 3.10 is rotationally connected to the transparent cover end plate 3.11 via a transmission shaft bearing 3.8. The output shaft then extends through an output shaft hole 3.11.4 in the transparent cover end plate 3.11 and into the inner transmission case 3, where it becomes transmission-connected there. The other end of the output shaft 3.10 is rotationally connected to the blind cover end plate 3.6 via a transmission shaft bearing 3.8. The reversing shaft 3.9 is rotationally connected to both the transparent cover end plate 3.11 and the blind cover end plate 3.6, respectively, via transmission shaft bearings 3.8. Inside the internal transmission case, one end of the output shaft 3.10 is rotationally connected to the transparent cover end plate 3.11 via a transmission shaft bearing 3.8. The output shaft then extends through an output shaft hole 3.11.4 in the transparent cover end plate 3.11 and connects to the low-speed shaft of the transmission 5 via a coupling 4. The other end of the output shaft 3.10 is rotationally connected to the transparent cover end plate 3.11 via a transmission shaft bearing 3.8. The two ends of the reversing shaft 3.9 are rotationally connected to the two transparent cover end plates 3.11 via transmission shaft bearings 3.8, respectively. A transparent cover seal 3.12 is installed on one side of the transparent cover end plate 3.11 at the connection between the output shaft 3.10 and the transmission shaft bearing 3.8. This seal prevents seawater or moisture 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 corrosion damage to the mechanical transmission components within the transmission case 3 and extending their service life. Two identical reversing gears 3.2 are mounted within the inner ring gear 3.1. These reversing gears 3.2 are externally meshed and fixedly mounted on the output shaft 3.10 and reversing shaft 3.9, respectively. Two axially positioned spacer sleeves 3.13 are also fixedly mounted on the output shaft 3.10 and reversing shaft 3.9, respectively. These 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 gears 3.2 and the transmission shaft bearing 3.8, respectively, to provide axial positioning and isolation for the components.

[0050] The installation method for two identical one-way clutch gears 3.3, each meshing with the internal teeth of the ring gear 3.1, within a transmission case 3 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 forward rotation, ensuring that only forward rotation of the one-way clutch gear 3.3 drives the output shaft 3.10 in forward rotation; otherwise, the gear will idle. Step 2: Set the driving direction of the one-way clutch gear 3.3 connected to the reversing shaft 3.9 to reverse rotation, ensuring that only reverse rotation of the one-way clutch gear 3.3 drives the reversing shaft 3.9 in reverse rotation; otherwise, the gear will idle. Step 3: Install the two one-way clutch gears 3.3 on the output shaft 3.10 and reversing shaft 3.9, respectively, with opposite driving directions.

[0051] In this embodiment, the two floats 1 are each excited by the waves, absorbing wave energy and vibrating up and down. When the waves rise, buoyancy lifts the floats 1 to a certain height, giving them potential energy. Simultaneously, the floats 1 drive the double rocker arms 2 to swing upward, generating work. When the waves recede, the floats 1 descend due to their own gravity, releasing potential energy while gravity drives the double rocker arms 2 downward, generating work. Two one-way clutch gears 3.3 within the transmission case 3 convert the bidirectional swinging rotation of the double rocker arms 2 into unidirectional rotation of the output shaft 3.10, which has both one-way transmission and one-way overrunning capabilities. Thus, the up and down motion of the two floats 1 is transformed into the superimposed rotational motion of the two one-way output shafts 3.10 of the transmission case 3. This rotational power is then transmitted to the generator 7 via the transmission 5 and flywheel 6, completing the conversion of wave energy into electrical energy.

[0056] The installation method of the series-connected double rocker arm and double float wave energy power generation device is as follows: Step 1: Complete the assembly of the transmission box 3 in accordance with the process requirements. Step 2: Complete the assembly of the double rocker arm 2 in accordance with the process requirements.

Step 6: Use the floating frame connection hole 8.2 on the fixed frame 8 to install and position the wave energy power generation device as a whole on the offshore floating platform or other offshore power generation structure.

[0057] During the manufacture and installation of the transmission case 3, the two one-way clutch gears 3.3 are simultaneously meshed with the internal teeth of the inner ring gear 3.1. The technical requirements for the gear transmission installation should meet the gear pair accuracy grade ISO 8 or above, with a normal side clearance of 0.08 to 0.13 mm. Seawater-resistant grease (such as composite calcium sulfonate-based grease or polyurea-based grease) must be used for lubrication.

[0058] The working principle of the present invention is as follows: for a transmission box 3, 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 shaft 2.6 at the intersection of the frame rod 2.1.1 and the long rocker 2.2; specifically, when the float 1 rises, the long rocker 2.2 rotates forward; when the float 1 sinks, the long rocker 2.2 reverses. 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 group 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. Since the one-way clutch gears 3.3 of the output shaft system and the reversing shaft system inside the transmission case are meshed with the internal teeth of the inner ring gear 3.1, and the reversing gears 3.2 on the output shaft system and the reversing shaft system are meshed with each other externally, the bidirectional rotational motion of the inner ring gear 3.1 will drive the one-way clutch gears 3.3 to perform bidirectional rotational motion around their respective axes, alternating between forward and reverse rotation. Specifically, when the inner ring gear 3.1 rotates forward, it drives the two one-way clutch gears 3.3 to rotate forward at the same time; when the inner ring gear 3.1 rotates reversely, it drives the two one-way clutch gears 3.3 to rotate reversely at the same time. When the one-way clutch gear 3.3 on the output shaft 3.10 rotates forward, it drives 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 forward rotation power of the one-way clutch gear 3.3 on the output shaft 3.10 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 upward stroke into electrical energy.When the one-way clutch gear 3.3 on the reversing shaft 3.9 rotates in the reverse direction, it drives the reversing shaft 3.9 to rotate in the reverse direction. Since a reversing gear 3.2 is fixedly mounted 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 drives the reversing gear 3.2 on the reversing shaft 3.9 in the reverse direction. Since the two reversing gears 3.2 are externally meshed, the reverse rotation of the reversing gear 3.2 on the reversing shaft 3.9 drives the reversing gear 3.2 on the output shaft 3.10 to rotate forward, thereby driving the output shaft 3.10 to rotate forward. Since the output shaft 3.10 passes through the coupling 4, the transmission 5, and the flywheel 6 on the outer side 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.

[0059] For a set of conversion modules (two transmission boxes 3), the output shaft 3.10 of the inner transmission box 3 is connected to the transmission 5 to generate electricity. When the power of the inner transmission box 3 is larger and its output speed exceeds the driving speed of the one-way clutch gear 3.3 in the outer transmission box 3, the speed of the output shaft 3.10 will unimpededly surpass the driving speed of the outer transmission box 3, and the power will eventually be transmitted to the generator 7; when the power of the outer transmission box 3 is larger and its output speed exceeds the driving speed of the one-way clutch gear 3.3 in the inner transmission box 3, the speed of the output shaft 3.10 will unimpededly surpass the driving speed of the inner transmission box 3, and the power will eventually be transmitted to the generator 7. Finally, the mechanical energy generated by the unidirectional rotational motion is converted into electrical energy through the generator 7, completing the whole process of converting wave energy into electrical energy.

[0060] Although the present invention has been described using the above preferred embodiments, they are not intended to limit the scope of protection of the present invention. Any person skilled in the art who makes various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention still fall within the scope of protection of the present invention.
