Description:Field of the Invention


The present disclosure relates to energy harvesting systems. Particularly, the present disclosure relates to a smart energy harvesting device, which utilizes a gear-based mechanism for converting wave motion into electrical energy, supported by intelligent control systems to optimize energy production.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Wave energy harvesting systems have been extensively researched in recent years. Such systems are aimed at capturing energy from the natural motion of ocean waves to generate electrical energy. The growing demand for renewable energy has led to increased interest in wave energy as a sustainable alternative to conventional energy sources. Energy conversion from wave motion involves various mechanical and electromechanical processes that harness the motion of waves and convert mechanical energy into electrical energy.
Various state-of-the-art systems are employed to capture wave energy. One well-known approach uses oscillating water columns, where the motion of waves pushes air through a turbine. Such systems utilise a chamber that oscillates with wave motion, causing airflow to rotate a turbine, thereby generating energy. However, the performance of oscillating water columns is often limited due to the variability in wave energy, resulting in low efficiency. Additionally, maintenance of turbines used in such systems presents challenges, particularly in offshore environments where corrosion and mechanical wear are significant concerns.
Another widely recognised method involves point absorber systems, which consist of floating structures that move with the wave motion. Energy is captured as the structure rises and falls with the waves, driving mechanical components to generate energy. Such systems are capable of capturing energy from multiple wave directions, enhancing energy capture efficiency. However, point absorbers are typically limited by their size and construction, making them less effective in areas with smaller or irregular waves. Moreover, the complexity of mechanical components and the constant exposure to harsh marine environments can lead to frequent mechanical failures, further complicating their long-term operation.
In addition to the aforementioned systems, attenuator-based wave energy devices are also employed. Such systems typically consist of a series of hinged floating structures arranged parallel to the direction of the waves. As waves pass through, the hinged structures move, and such motion drives hydraulic pumps to generate energy. While attenuator systems are capable of capturing significant amounts of energy from wave motion, said systems are often large in size and complex in construction, which can lead to high installation and maintenance costs. Furthermore, energy conversion efficiency may be reduced in low-wave conditions, which limits the application of such systems in certain marine environments.
Other existing systems also exist for wave energy harvesting, including overtopping devices, which use ramps to capture wave energy as water flows over them. However, such systems are often expensive to construct and require large structures that may not be feasible in all marine environments. Moreover, overtopping devices are highly dependent on wave height, making them unsuitable for areas with low-energy waves. Furthermore, the variability in wave motion makes it difficult to maintain consistent energy generation, which is a major limitation of overtopping systems.
Moreover, systems employing mechanical linkages that convert wave motion into rotational energy are also present. Such systems often use gears, levers or mechanical arms that move with the waves. Energy conversion efficiency in such systems is highly dependent on the accuracy and durability of mechanical components. However, exposure to constant wave motion and the harsh marine environment can lead to mechanical wear and failure, thereby reducing the overall lifespan and reliability of such systems. Additionally, mechanical systems often suffer from frictional losses, which can reduce the efficiency of energy conversion, particularly in cases where wave motion is inconsistent or low in intensity.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for harvesting wave energy.
All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.

In an embodiment, the first gear 102 and the second gear 104 of the wave energy harvesting system are bevel gears, which are configured to transmit rotational motion to the third gear 106 at an angle. Bevel gears are specifically designed to change the axis of rotation by transmitting motion between intersecting shafts. In the present embodiment, the teeth of said bevel gears are angled and oriented to mesh smoothly with said third gear 106, allowing for a seamless transfer of rotational energy. The unique design of bevel gears enables the redirection of rotational motion from the vertical axis of said first and second gears to the horizontal axis of said third gear 106. This angular transmission ensures that energy captured from the upward and downward movements of the waves is efficiently transferred to the third gear 106, which in turn drives the generator 114. The configuration and material composition of said first gear 102 and said second gear 104 are selected to withstand continuous exposure to the aquatic environment, preventing wear and tear while maintaining smooth gear engagement. The alignment of said bevel gears within the housing 108 ensures that rotational energy is transferred effectively, enabling the continuous operation of the wave energy harvesting system even under varying wave conditions.
In an embodiment, the buoyancy support 112 comprises a flotation device configured to maintain said housing 108 at a constant depth relative to the water surface. Said flotation device is designed to ensure that the system remains at an optimal depth for harvesting wave energy, regardless of variations in water level. The flotation device may be constructed from lightweight, buoyant materials such as high-density foam or sealed air-filled chambers, which provide the necessary buoyancy to support the weight of said housing 108 and the internal components. The placement of said buoyancy support 112 allows the system to adjust to rising and falling water levels while keeping the gears and generator submerged at the appropriate depth to interact effectively with wave motion. The flotation device may be designed to include adjustable ballast or other mechanisms that enable fine-tuning of the buoyancy level, ensuring that the system remains stable and operational even in fluctuating tidal conditions. The buoyancy support 112 plays a vital role in maintaining the overall stability of the system, reducing the likelihood of excessive vertical movement that could disrupt the internal gear operation.
In an embodiment, said generator 114 is configured to convert the rotational energy generated by said third gear 106 into electrical energy through an electromagnetic induction process. Electromagnetic induction is a process by which a conductor, such as a wire coil, is moved through a magnetic field, inducing an electrical current within the conductor. In the present system, the rotational motion of said third gear 106 is mechanically transferred to the generator 114, which contains components such as a rotor and a stator. The rotor, which is connected to said third gear 106, rotates within a magnetic field generated by the stator. As the rotor moves, the changing magnetic field induces an electrical current in the stator coils. Said generator 114 is designed to maximize the efficiency of this conversion process, ensuring that the mechanical energy harvested from the wave motion is effectively transformed into usable electrical energy. The generator 114 may include features such as voltage regulation and power output stabilization to ensure that the generated electricity can be stored or used directly in external systems. The housing of said generator 114 is sealed to protect the internal components from exposure to water and environmental elements.
In an embodiment, said housing 108 comprises multiple through holes 110 that are strategically placed to allow water to flow through during operation, thereby reducing drag on said third gear 106. The placement and size of said through holes 110 are optimized to ensure that the flow of water through said housing 108 does not interfere with the rotation of the internal gears. The reduction of drag is important in maintaining the efficiency of the wave energy harvesting system, as unnecessary resistance caused by water flow can hinder the rotational motion of said third gear 106. The design of said through holes 110 may vary depending on the specific environmental conditions, such as wave size and water flow rate. Additionally, said through holes 110 ensure that water can enter and exit said housing 108 freely, preventing pressure buildup inside said housing 108. The material used for said housing 108 is selected to withstand the harsh conditions of the marine environment, while the placement of said through holes 110 ensures that internal components remain protected from debris and sediment while still allowing necessary water flow.
In an embodiment, said first gear 102 is connected to a vertical shaft that is configured to capture the vertical motion of the wave and transfer this motion into rotational energy. The vertical shaft is designed to move up and down in response to the rise and fall of the wave surface, effectively translating the vertical kinetic energy into rotational motion. Said first gear 102 is attached to the shaft in such a way that the vertical movement causes the gear to rotate around its axis. The connection between the vertical shaft and said first gear 102 is secured to ensure that the energy transfer remains smooth and uninterrupted, even under varying wave intensities. The vertical shaft may be constructed from corrosion-resistant materials, such as stainless steel or composite materials, to prevent degradation over time due to exposure to seawater. The shaft length and flexibility are adjusted to ensure that the energy transfer is maximized while minimizing mechanical strain on said first gear 102. This configuration allows the wave energy harvesting system to capture more energy from vertical wave motion and efficiently transmit it through the system.
In an embodiment, said third gear 106 is coupled to a gear ratio adjustment unit that is configured to control the speed of rotation transmitted to said generator 114. The gear ratio adjustment unit is designed to modify the rotational speed of said third gear 106, ensuring that the output speed matches the optimal input speed for said generator 114. This adjustment is necessary because the rotational speed of said third gear 106 may vary based on the intensity of the wave motion, which could result in inconsistent or suboptimal energy output if directly transferred to said generator 114. The gear ratio adjustment unit may include various mechanical components such as differential gears, planetary gears, or adjustable pulleys that enable dynamic control of the gear ratio. The unit ensures that even when said third gear 106 rotates at fluctuating speeds, the speed transmitted to said generator 114 remains within a range that maximizes electrical energy generation. The adjustment unit is housed within said system 100 and is constructed from durable materials that can withstand the mechanical stress of continuous operation in a marine environment.
In an embodiment, said buoyancy support 112 is further configured to stabilize said housing 108 during high wave conditions, facilitating continuous gear rotation. High wave conditions can introduce instability into floating systems, potentially disrupting the rotation of internal components such as said first gear 102, said second gear 104, and said third gear 106. To address this, said buoyancy support 112 is designed to include stabilizing features such as weighted ballasts, gyroscopic stabilizers, or dynamically adjustable buoyant chambers. These stabilizing elements work to counteract the motion of large or turbulent waves, maintaining the alignment and proper functioning of the system's internal gears. By stabilizing said housing 108, said buoyancy support 112 ensures that the system remains functional even in rough sea conditions, preventing interruptions in the transfer of wave energy to the generator 114. The material and construction of said buoyancy support 112 are selected to provide both buoyancy and stability, ensuring that the system remains operational under a wide range of environmental conditions.
In an embodiment, said generator 114 comprises an energy storage unit that is configured to store the electrical energy generated by the rotation of said third gear 106. The energy storage unit may be integrated within said generator 114 or housed separately within the system. Said energy storage unit is designed to store the generated electrical energy for later use, allowing the system to provide a continuous energy supply even when wave motion is inconsistent. The energy storage unit may include components such as batteries, capacitors, or other energy storage devices that can efficiently capture and store the electrical energy produced by said generator 114. The connection between said generator 114 and said energy storage unit is designed to allow for efficient energy transfer, with minimal loss during storage. The energy storage unit may also include features such as charge controllers and voltage regulators to ensure that the stored energy can be delivered in a stable and usable form when needed. Said energy storage unit is protected from environmental exposure by a sealed housing that prevents water ingress and corrosion.
In an embodiment, said first gear 102 and said second gear 104 are configured to rotate simultaneously based on opposing wave motions. Said first gear 102 rotates in response to the upward movement of the wave, while said second gear 104 rotates in response to the downward movement of the wave. The simultaneous rotation of said first gear 102 and said second gear 104 ensures that energy is captured from both the rising and falling phases of the wave cycle. The interaction between said first gear 102 and said second gear 104 is facilitated by their positioning within the housing 108, allowing them to engage smoothly with each other and with said third gear 106. The simultaneous rotation of said first gear 102 and said second gear 104 allows for a more consistent and efficient transfer of energy to said third gear 106, maximizing the overall energy output of the system. Both gears are constructed from materials that are resistant to the harsh marine environment, ensuring long-term durability and consistent operation.
The disclosed smart energy harvesting device is a wave energy harvesting system (100) that efficiently captures the kinetic energy generated by ocean waves and converts it into usable electrical power. The system is structured around a gear-based mechanism, where a first gear (102) rotates in response to upward wave motion, and a second gear (104) rotates in the opposite direction during the downward motion of the waves. Situated between these gears, a third gear (106) is designed to rotate regardless of which gear is in motion, thereby enabling continuous energy conversion from both wave movements. The gears are housed within a protective enclosure (108), which features a through hole (110) at the position of the third gear, facilitating easy access and maintenance. A buoyancy support (112) keeps the system afloat on the water surface, ensuring consistent operation in various sea conditions. The rotational movement of the third gear (106) is transmitted to a generator (114), which produces electrical energy. The system is considered "smart" because it can intelligently adapt to changing wave conditions, maximizing energy output while minimizing wear on mechanical components. Integrated sensors or control algorithms monitor wave patterns, adjusting gear engagement and generator load to optimize efficiency. This smart energy harvesting device is suitable for renewable energy applications in offshore environments, providing a reliable source of clean energy while leveraging advanced control mechanisms to adapt to environmental conditions.
FIG. 2 illustrates sequential diagram of a wave energy harvesting system (100), in accordance with the embodiments of the present disclosure. The diagram illustrates the sequence of operations in a wave energy harvesting system. It starts with water waves causing vertical motion, which is then supported by the buoyancy support (112), ensuring that the system remains afloat. The vertical motion is transferred to the housing (108) that encloses the internal components. When the water waves move upward, the first gear (102) rotates, and when the water waves move downward, the second gear (104) rotates in the opposite direction. Both gears transmit their rotational motion to the third gear (106), which is positioned between them. The third gear (106) collects rotational energy from either the first or second gear, depending on the direction of wave motion. This energy is further transmitted to the generator (114), which is coupled to the third gear. The generator (114) then converts the rotational mechanical energy into electrical energy, which can be harvested from the system. The entire process is continuous, capturing energy from the up-and-down motion of waves.
In an embodiment, the first gear 102 rotates in response to the upward wave motion, while the second gear 104 rotates in the opposite direction in response to the downward wave motion. This dual-motion configuration allows the wave energy harvesting system 100 to capture energy from both the rising and falling movements of waves, maximizing the energy extracted from the entire wave cycle. By having said first gear 102 and said second gear 104 rotate in opposing directions, continuous energy transfer is enabled, reducing idle time between wave peaks. The counter-rotation of the gears ensures a balanced force distribution within the system, minimizing mechanical strain on components and enhancing the durability of the system over extended use. This configuration also ensures that energy is captured regardless of wave height or intensity, making the system adaptable to various marine environments.
In an embodiment, the first gear 102 and second gear 104 are bevel gears that transmit rotational motion to the third gear 106 at an angle. This angular transmission enables a smooth and efficient redirection of energy from the vertical axis of the first and second gears to the horizontal axis of the third gear 106. The use of bevel gears optimizes the spatial arrangement within the housing 108, ensuring that rotational motion is effectively transferred across different planes without loss of energy. The angled transmission reduces mechanical stress on the gears, allowing for more consistent energy transfer even under fluctuating wave conditions. The bevel gear configuration also facilitates compactness in the system design, providing the ability to accommodate all components within the housing 108 while maintaining optimal gear alignment and functionality. This feature enhances the overall performance of the wave energy harvesting system by ensuring continuous energy capture.
In an embodiment, the buoyancy support 112 comprises a flotation device that maintains the housing 108 at a constant depth in relation to the water surface. This design feature enables the system to remain positioned at an optimal depth, regardless of changes in wave height or tidal levels. By maintaining a stable depth, the gears inside the housing 108 can continuously interact with the wave motion, allowing for uninterrupted energy capture. The constant depth positioning minimizes the risk of the system becoming submerged too deeply or rising above the water, both of which could negatively impact energy capture efficiency. The flotation device is constructed to be highly resistant to water absorption and environmental degradation, ensuring long-term stability of the system. This feature is particularly beneficial in varying sea conditions, as it prevents the housing 108 from drifting or bobbing excessively, maintaining consistent interaction with the wave motion.
In an embodiment, the generator 114 converts the rotational energy from the third gear 106 into electrical energy through an electromagnetic induction process. As the third gear 106 rotates, mechanical motion is transmitted to a rotor within the generator 114. Said rotor interacts with a magnetic field, inducing an electric current in the surrounding stator coils. This conversion process allows the system 100 to transform mechanical wave energy into usable electrical energy. The design of the generator 114 ensures minimal energy loss during the conversion process, enabling high-efficiency energy generation. The components within the generator 114 are housed in a protective enclosure to prevent exposure to seawater and corrosion, which enhances the durability and reliability of the electrical generation process. This allows the wave energy harvesting system to provide continuous electrical power output, even in chal
