Description

Technical Field

[0001] This invention belongs to the field of wave energy power generation technology, specifically a multi-degree-of-freedom wave energy power generation device based on the coupling of multiple power generation scenarios. Background Technology

[0002] Electricity is an energy source that uses electrical energy as power. With the development of the times, we still have a continuously growing demand for electricity. The current mainstream power generation methods have disadvantages such as causing environmental pollution, adverse effects on people's lives and plant growth, and excessively high costs.

[0003] With the research on clean energy conversion methods, ocean energy, such as wave energy, has become a key research focus. Wave energy is a specific form of ocean energy and one of the most important energy sources in the ocean. Its development and utilization are crucial for alleviating the energy crisis and reducing environmental pollution. The surging movement of ocean waves generates enormous, perpetual, and environmentally friendly energy. If the kinetic energy of ocean waves and other surface wave energy can be fully utilized, the future of global energy will be quite broad and bright. Wave power generation uses the energy of waves as a power source to produce electricity. Ocean waves contain enormous energy, which can be converted into mechanical, pneumatic, or hydraulic energy through a certain device. This energy is then used to drive a generator through a transmission mechanism, steam turbine, water turbine, or hydraulic motor to generate electricity. This reduces the negative environmental impact during power generation, and the cost decreases with the change in power generation method compared to some other power generation methods. Therefore, there is an urgent need for a more efficient and convenient power generation device to fully utilize the infinite potential of wave energy. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems by proposing a multi-degree-of-freedom wave energy power generation device based on the coupling of multiple power generation scenarios. This application utilizes the torque generated by ocean waves to apply pressure to a rotating disk, thereby driving an internal geared mechanical generator to generate electricity. Furthermore, the undulation of the sea surface or the impact force of ocean waves causes the transmission box to oscillate, which in turn drives the adjustment components set between the chassis and the transmission box to move, thereby driving the transmission shaft and transmission wheel connected to the generator to rotate, thus achieving power generation. Through the above process, this device realizes the coupling of at least two power generation scenarios (the thrust of ocean currents, the impact force of ocean waves, and the height difference of sea surface undulations), different degrees of freedom in the upper and lower sections (using wave energy in different planes), and different dimensions (the direction of the ocean waves) to generate wave energy. Moreover, these power generation modes are coupled with each other and are independent of each other. They can generate electricity independently or superimpose each other depending on the ocean conditions, thus significantly improving efficiency compared to a single power generation method.

[0008] Preferably, the transmission assembly includes a transmission shaft disposed on the same side of the transmission box and the chassis, and a transmission wheel is fixedly disposed at the end of the transmission shaft connected to the chassis, and a transmission belt is disposed inside the groove of the transmission wheel.

[0009] Preferably, the adjustment assembly includes mounting brackets fixedly installed on one side of both the transmission box and the chassis. A rotating plate is rotatably connected to the middle of the mounting bracket body towards the side away from the transmission box or chassis. A movable frame is rotatably connected between the rotating plates. A guide rod passes through the middle of the movable frame. A top spring is sleeved on the outer side of the guide rod body. A guide frame is fixedly installed at the end of the guide rod away from the transmission box. A guide wheel is rotatably connected to the middle of the guide frame body. A balance float is fixedly sleeved on the outer side of the top of the transmission box.

[0010] Preferably, a generator is fixedly installed inside the chassis, a drive shaft is fixedly installed at one end of the generator and extends through the side wall of the chassis, a drive wheel is fixedly installed at the end of the drive shaft, and another set of drive shafts and drive wheels are installed at one end of the drive gear roller in the same manner.

[0011] Preferably, a connecting rod is fixedly provided at the top of the lifting plate, and a float is fixedly provided at the top of the connecting rod.

[0012] Preferably, the included angle between the fixing brackets at both ends of the chassis is ninety degrees.

[0013] Preferably, a fixed vertical plate with a guide plate is fixedly installed on one side of the chassis, and the fixed vertical plate is oriented in the same direction as the fixed frame at the top of the chassis.

[0014] Preferably, the bottom end of the supporting base plate is symmetrically provided with fixed legs, and the bottom plate of the fixed legs is provided with fixing holes for fixed installation. The side of the chassis without the fixed installation guide plate is provided with a fixing device to connect with the marine structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This application utilizes the torque generated by ocean waves to apply pressure to a rotating disk, thereby driving an internal geared mechanical generator to generate electricity. Furthermore, the undulation of the sea surface or the impact force of ocean waves causes the transmission box to oscillate, which in turn drives the adjustment components set between the machine and the transmission box to move, thereby driving the transmission shaft and transmission wheel connected to the generator to rotate, thus achieving power generation. Through the above process, this device realizes the coupling of at least two power generation scenarios (the thrust of ocean currents, the impact force of ocean waves, and the height difference of sea surface undulations), different degrees of freedom in the upper and lower sections (using wave energy in different planes), and different dimensions (the direction of the ocean waves) to generate electricity using wave energy. Moreover, these power generation modes are coupled with each other and are independent of each other. They can generate electricity independently or superimpose each other depending on the ocean conditions, which greatly improves the efficiency compared to a single power generation method.

[0016] 2. This invention designs two sets of fixed frames and connecting plates with an included angle of 90 degrees, allowing the transmission box and the machine housing to rotate along the angle of the connecting plate. The overall structure allows the float and transmission shaft at the top of the device to swing in the direction of the waves. The float moves up and down with the waves, causing the lifting plate to move up and down, so that the teeth on one side of the lifting plate mesh with the transmission roller. The transmission roller then drives the corresponding transmission shaft and transmission wheel to rotate, thereby driving the transmission belt to move and driving the transmission shaft and transmission wheel connected to the generator to rotate, thus generating electricity.

[0017] 3. The present invention enables the transmission box to rotate along the corresponding fixed frame and connecting plate through the transmission component. The rotating plate rotates with the mounting frame as the base point. The two rotating plates match the moving frame and change angle. The top spring tightens the guide frame and guide wheel to apply force, so that the transmission belt remains taut and ensures its transmission capacity.

[0018] 4. The present invention, through the setting of a fixed ring seat, a rotating disk, a limiting frame, limiting balls, a limiting groove, and a guide plate, enables the device to rotate as a whole when facing different waves. The impact of the waves on the guide plate causes the rotating disk to rotate and generate electricity. At the same time, it better adapts to the impact direction of the waves, reduces the direct impact force of the waves on the device, and extends the service life of the device.

[0019] 5. In this invention, when the transmission box is subjected to the impact of waves, it swings along the connecting plate and fixed frame at its bottom, causing the float to move up and down, which in turn moves the connecting rod up and down, thus causing the lifting plate to move up and down. This causes the transmission teeth and transmission rollers on one side of the lifting plate to mesh, causing the transmission rollers to rotate, which in turn drives the corresponding transmission shaft and transmission wheel to rotate, thereby driving the corresponding transmission belt to move. When the transmission belt moves, it drives the transmission shaft and transmission wheel installed at the end of the generator to rotate, allowing the rotor inside the generator to rotate in the stator, cutting magnetic lines of force and generating an induced electromotive force. This induced electromotive force is led out through the terminals and connected to a circuit to generate current, thus realizing power generation. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please see Figure 1-9 This invention provides a multi-degree-of-freedom wave energy generation device based on coupling multiple power generation scenarios, including a supporting base plate 1 and a float 30. A fixed ring seat 4 is fixedly installed at the top of the supporting base plate 1. A rotating disk 5 is clamped inside the fixed ring seat 4. The external structure of the rotating disk 5 is similar to that of a bearing, and it can rotate under external force. A limiting groove 8 is opened on the top surface of the rotating disk 5. The groove 8 is arc-shaped and forms a circular closed loop. A limiting frame 6 is symmetrically fixed on the outside of the fixed ring seat 4. The limiting frame 6 is U-shaped. A seated limiting ball 7 is fixedly installed at the bottom of the limiting frame 6. The limiting ball 7 is inverted and downward and contacts the inner wall of the limiting groove 8. The limiting frame 6 and the limiting ball 7 together press and fix the rotating disk 5 to ensure the rotational stability of the rotating disk 5.

[0024] A fixed frame 9 is fixedly installed at the top center of the rotating disk 5. A connecting plate 10 is fixedly connected to the middle of the frame 9. The fixed frame 9 consists of two fixed vertical plates and a horizontal shaft. The horizontal shaft passes through the connecting plate 10, so that the connecting plate 10 can maintain its rotation function.

[0025] There are two sets of fixing brackets 9 and connecting plates 10, and the included angle between the two sets of fixing brackets 9 is 90 degrees, which facilitates the rotation of the components connected to them.

[0026] The modular distribution allows the corresponding components to oscillate freely in multiple degrees, enabling wave energy generation in multiple power generation scenarios and with multiple degrees of freedom. A housing 11 is fixedly mounted on the top of the connecting plate 10, and a generator 13 is fixedly mounted inside the housing 11. The generator 13 consists of a stator 45, a rotor 42, a generator housing 41, and a shaft 44. The rotor 42 consists of a rotor core winding, retaining rings, a center ring, slip rings, a cooling fan 43, and a shaft 44. The shaft 44 and the generator housing 41 connect and assemble the stator 45 and rotor 42 of the generator 13, allowing the rotor 42 to rotate within the stator 45, cutting magnetic lines of force and generating an induced electromotive force. This induced electromotive force is led out through the terminal 46 and connected to a circuit, thus generating current. The specific structure is as follows: Figure 8 As shown.

[0027] A drive shaft 31 is fixedly mounted at one end of the generator 13, extending through the side wall of the housing 11. A drive wheel 14 is fixedly mounted at the end of the drive shaft 31. Another set of drive shafts 31 and drive wheels 14 are mounted at one end of the drive roller 28 in the same manner. The drive wheel 14 has toothed grooves inside its groove. A fixed vertical plate with a guide plate 12 is fixedly installed on the other side of the housing 11. The fixed vertical plate is fixed to the side of the housing 11 by bolts. A transmission box 23 is fixedly connected to the top of the housing 11 by another fixed bracket 9 and a connecting plate 10. The transmission box 23 is equipped with... The transmission assembly includes a guide rail 25, a lifting plate 26, transmission teeth 27, and a transmission roller 28. Guide rails 25 are provided on both inner walls of the transmission box 23. A lifting plate 26 is clamped between the two guide rails 25. A connecting rod 29 is fixedly provided at the top of the lifting plate 26. A float ball 30 is fixedly provided at the top of the connecting rod 29. A transmission tooth 27 is provided on one side of the lifting plate 26. A transmission roller 28 is provided on one side of the transmission tooth 27. A transmission shaft 31 is fixedly provided at one end of the transmission roller 28. The transmission shaft 31 extends through one side wall of the transmission box 23.

[0028] Please see Figure 1-9 The transmission box 23 and the machine box 11 are provided with a transmission assembly on the same side. The transmission assembly includes a transmission shaft 31, a transmission wheel 14, and a transmission belt 15. There are four sets of transmission shafts 31, transmission wheels 14, and transmission belts 15, which are respectively provided at the ends of the transmission toothed rollers 28 and the generator 13, as well as on the sides of the transmission box 23 and the machine box 11. The transmission wheels 14 and the transmission belts 15 are in the same plane, which facilitates smoother transmission. The transmission box 23 and the machine box 11 are both provided with a transmission shaft 31. The transmission wheel 14 is fixedly provided at the end of the transmission shaft 31. The transmission belt 15 is provided inside the groove of the transmission wheel 14. The inner side of the transmission belt 15 is provided with matching tooth grooves at the contact position with the groove of the transmission wheel 14, which increases the friction between the two and facilitates linkage and transmission. When waves impact the device, they first impact the guide plate 12 on one side of the chassis 11, causing it to be subjected to impact force. Simultaneously, the fixed frame 9 and connecting plate 10 at the lower end of the chassis 11 are subjected to torque. On one hand, the fixed frame 9 and connecting plate 10 apply torque to the rotating disk 5, causing it to rotate within the fixed ring seat 4, thus rotating the chassis 11. After the chassis 11 rotates, the guide plate 12 deviates to the side in the same direction as the wave impact force. During this process, the seated limiting ball 7 on the bottom surface of the limiting frame 6 moves relative to the limiting groove 8, applying pressure to the rotating disk 5 to ensure its stable rotation, thereby driving the internal gear mechanical generator to generate electricity. On the other hand, the sea level in the same area as the device fluctuates, causing the transmission box 23... Facing the impact of waves, the transmission box 23 swings along the connecting plate 10 and the fixed frame 9 at its bottom when impacted by waves. This causes the float 30 to move up and down, which in turn moves the connecting rod 29 up and down, thus causing the lifting plate 26 to move up and down. This causes the transmission teeth 27 and transmission roller 28 on one side of the lifting plate 26 to mesh, causing the transmission roller 28 to rotate. This, in turn, causes the corresponding transmission shaft 31 and transmission wheel 14 to rotate, which in turn causes the corresponding transmission belt 15 to move. When the transmission belt 15 moves, it causes the transmission shaft 31 and transmission wheel 14 installed at the end of the generator 13 to rotate, so that the rotor inside the generator 13 can rotate in the stator and cut magnetic lines of force, thereby generating an induced electromotive force. This induced electromotive force is led out through the terminal block and connected to the circuit to generate current and realize power generation.

[0029] Please see Figure 1-9Both the transmission box 23 and the chassis 11 have fixed adjustment components on their backs. These components include a mounting bracket 16, a rotating plate 17, a movable bracket 18, a guide rod 19, a top spring 20, a guide frame 21, and a guide wheel 22. The mounting bracket 16 is composed of a fixed block with a notch and a shaft inside the notch. The shaft passes through one end of the rotating plate 17. The rotating plate 17 is rotatably connected to the middle of both mounting brackets 16. A movable bracket 18 is rotatably connected to the other end of the rotating plate 17. A through shaft is mounted at both ends of the movable bracket 18, passing through the other end of the rotating plate 17. The rotating plate 17 retains its active capability. A guide rod 19 passes through the middle of the movable bracket 18. A top spring 20 is sleeved on the outer side of the guide rod 19. A guide frame 21 is fixedly installed at the end away from the transmission box 23. A guide wheel 22 is rotatably connected to the middle of the guide frame 21. The top spring 20 pushes the guide rod 19 away from the chassis 11, so that the guide frame 21 and the guide wheel 22 obtain thrust, which pushes the transmission belt 15 to make it taut. A balance float 24 is fixedly sleeved on the outer side of the top of the transmission box 23 to facilitate the rapid reset of the transmission box 23 and reduce the impact of sea waves on the side of the device. Fixed legs 2 are symmetrically arranged at the bottom of the support base plate 1. The fixed legs 2 have fixed holes 3 for fixed installation. They are mainly used to fix the device in a suitable sea area. At the same time, according to the main marine engineering structure of the actual sea area, the side of the chassis 11 can be connected to the marine engineering structure such as offshore wind power by using the fixed device to realize comprehensive energy utilization. When using the device, firstly, based on the actual conditions of the local sea area, use appropriate fixing parts to fix the fixed legs 2 to the seabed, or use fixing devices to connect the side of the chassis to offshore wind power and other marine engineering structures. During the power generation process, as the float 30, connecting rod 29, and transmission box 23 rotate along the fixed frame 9 with the connecting plate 10, the angle between the transmission box 23 and the chassis 11 changes. The two ends of the rotating plate 17 rotate relative to each other on the mounting frame 16 and the moving frame 18, respectively. During this process, the guide rod 19 is lifted by the top spring 20 to support the guide frame 21, so that the guide wheel 22 supports the transmission belt 15, keeping the transmission belt 15 taut. This ensures that even when the angle between the transmission box 23 and the chassis 11 changes, the transmission wheel 14 and the transmission belt 15 can still complete the transmission. When this application embodiment is used: When using this device, the fixed legs 2 are first fixed to the seabed using corresponding fixing parts. During power generation, or by using fixing devices to connect the side of the chassis to offshore wind power and other marine engineering structures, waves impact the guide plate 12 on one side of the chassis 11, causing the guide plate 12 to be subjected to impact force. At the same time, the fixing frame 9 and connecting plate 10 at the lower end of the chassis 11 are subjected to torque, causing the fixing frame 9 and connecting plate 10 to apply torque to the rotating disk 5, causing the rotating disk 5 to rotate within the fixing ring seat 4, thereby causing the chassis 11 to rotate. After the chassis 11 rotates, the guide plate 12 is subjected to torque. When plate 12 is tilted to the side in the same direction as the impact of the waves, the seated limiting ball 7 on the bottom surface of the limiting frame 6 moves relative to the limiting groove 8, applying pressure to the rotating disk 5 to ensure its stable rotation. This drives the internal gear mechanical generator to generate electricity. The seawater level in the same area as the device fluctuates up and down, and the transmission box 23 faces the impact of the waves. When the transmission box 23 is subjected to the impact of the waves, it swings along the connecting plate 10 and the fixed frame 9 at its bottom. As the float 30, connecting rod 29 and transmission box 23 follow the connecting plate 10 along the fixed frame 9, the transmission box 23 swings along the fixed frame 9. When frame 9 rotates, the angle between transmission box 23 and housing 11 changes, and the two ends of rotating plate 17 rotate relative to each other on mounting frame 16 and moving frame 18 respectively. During this process, guide rod 19 is lifted by top spring 20 to support guide frame 21, so that guide wheel 22 supports transmission belt 15, keeping transmission belt 15 taut. Even when the angle between transmission box 23 and housing 11 changes, transmission wheel 14 and transmission belt 15 can still complete transmission. Float ball 30 moves up and down, driving connecting rod 29 to move up and down, thereby raising and lowering... The plate 26 moves up and down, causing the transmission teeth 27 and transmission roller 28 on one side of the lifting plate 26 to mesh, causing the transmission roller 28 to rotate, which drives the corresponding transmission shaft 31 and transmission wheel 14 to rotate, thereby driving the corresponding transmission belt 15 to move. When the transmission belt 15 moves, it drives the transmission shaft 31 and transmission wheel 14 installed at the end of the generator 13 to rotate, so that the rotor inside the generator 13 can rotate in the stator and make a movement that cuts the magnetic lines of force, thereby generating an induced electromotive force. This is led out through the terminal and connected to the circuit to generate current and realize power generation.

[0030] This application utilizes the torque generated by ocean waves to apply pressure to a rotating disk, thereby driving an internal geared mechanical generator to generate electricity. Furthermore, the undulation of the sea surface or the impact force of ocean waves causes the transmission box to oscillate, which in turn moves the adjustment components set between the chassis and the transmission box, driving the transmission shaft and transmission wheel connected to the generator to rotate, thus generating electricity. Through the above process, this device achieves the coupling of at least two power generation scenarios (the thrust of ocean currents, the impact force of ocean waves, and the height difference of sea surface undulations), different degrees of freedom in the upper and lower sections (using wave energy in different planes), and different dimensions (the direction of the ocean waves) to generate electricity using wave energy. Moreover, these power generation modes are coupled with each other and are independent of each other. They can generate electricity independently or superimpose each other depending on the ocean conditions, which greatly improves the efficiency compared to a single power generation method.
