Description

Technical Field

[0001] The present invention belongs to the technical field of renewable energy ocean power generation, and in particular relates to an ocean power generation device which utilizes ocean currents and waves to generate electricity. Background Art

[0002] As an emerging renewable energy source, ocean energy has significant advantages, and its periodicity and regularity are very strong. Tides are caused by the gravitational effects of the moon and the sun, and their changes can be accurately predicted; at the same time, oceanography has already completed theoretical research on ocean currents in various regions, and information such as the direction and speed of ocean currents can also be accurately predicted.

[0003] At present, the most common ocean energy power generation devices are tidal power stations, which use the rise and fall of tides to drive generators to generate electricity. Although tidal power generation is a relatively mature technology, it has high construction and maintenance costs and requires specific geographical conditions, such as coastlines with large tidal ranges. In addition, the construction of large power stations may also cause certain interference to the marine ecosystem. For example, tidal dams may affect the migration and habitat of fish and destroy the local ecological balance.

[0004] The fixed location and size of tidal power stations make them less flexible and unable to adapt to the needs of different regions and environments. These limitations have led to certain restrictions on the promotion and application of tidal power stations. Therefore, how to use ocean energy for power generation more efficiently and economically without relying on specific geographical conditions has become an urgent problem to be solved.

[0005] In addition to tidal power generation, there are many other forms of ocean energy generation, including wave power generation, ocean current power generation and temperature difference power generation. These technologies have demonstrated the great potential of ocean energy as a renewable energy source to varying degrees. For example, wave power generation uses the up and down movement of waves to drive generators; ocean current power generation uses the continuous flow of ocean currents to drive generators; and temperature difference power generation uses the temperature difference between the surface and deep layers of seawater to convert heat energy.

[0006] Although these technologies have their own advantages, they also face some common problems. The first is the maturity of the technology. Many ocean energy power generation technologies are still in the research and development and experimental stages, and there is still a long way to go before large-scale commercial applications. The second is the cost issue. The initial construction cost and maintenance cost of ocean energy power generation devices are generally high, and the harsh conditions of the marine environment also increase the durability and reliability requirements of the devices. Finally, there is the issue of environmental impact. Although ocean energy power generation is relatively environmentally friendly, its potential impact on the marine ecosystem still needs further research and evaluation. Summary of the invention

[0031] In short, as the global demand for renewable energy continues to grow, ocean energy power generation, as a form of renewable energy with great potential, will play an important role in the future energy structure. Through continuous technological innovation and optimization, ocean energy power generation devices will achieve more efficient, more economical and more environmentally friendly energy production, and contribute to the sustainable development of the global energy system.

[0032] The present invention provides an ocean energy power generation device that uses ocean currents and waves to generate electricity. The device captures the kinetic energy of ocean currents and waves and converts it into electrical energy by installing a generator on the hull. Compared with traditional tidal power generation, the ocean energy power generation device of the present invention can not only greatly reduce construction and maintenance costs, but also effectively reduce the impact on the marine ecosystem, and has broad application prospects.

[0033] An ocean energy power generation device that uses ocean currents and waves to generate electricity. An ocean current generator device, a wave current generator device, a transformer device and an intelligent control module are installed on a ship hull to capture the kinetic energy of ocean currents and waves and convert it into electrical energy; the ocean current generator device is connected and controlled by a connecting arm device; the wave current generator device is fixed on the outside of the hull; the transformer device and the intelligent control module are placed inside the hull.

[0034] Specific embodiments, such as Figures 1 to 6 As shown, A marine energy power generation device that utilizes ocean currents and waves to generate electricity, comprising a hull D2, a connecting arm device, an ocean current generator device, a wave current generator device, a transformer device and an intelligent control module. The hull serves as a buoyancy providing device for the entire generator device to float on the water surface, so that the two types of main generators are always in a stable state when utilizing ocean energy as energy input and generating electricity. The hull is connected to the connecting arm device to provide a stable environment for the connecting arm to control the position and height of the ocean current generator, and serves as an attachment device for the intelligent control module.

[0035] The connecting arm device can control the position and height of the ocean current generator, so that the ocean current generator is always in the best state of utilizing the ocean current energy, and can control the overall dynamic balance by controlling the vector moment of the ocean current generator with respect to the whole.

[0036] The ocean current generator device is composed of main parts such as fan blades, fan shaft, and generator set. It can utilize ocean energy tangential to the sea surface, that is, ocean current energy, which is driven by ocean current energy to rotate the fan blades around the fan shaft and convert it into electrical energy through the generator set. The ocean current drives the propeller to rotate, and the generator is driven to generate electricity through the transmission of the gear set. The design focus of the ocean current generator is to efficiently capture the energy of the ocean current and maintain stable power generation efficiency at different ocean current speeds. The shape and material selection of the propeller are carefully designed to ensure optimal power transmission and durability.

[0037] The main device of the wave-current generator device is a resonator, which utilizes the ocean energy about the normal direction of the sea surface, that is, the drive of wave energy, and utilizes inertia to make the resonator rotate relative to the hull, and convert it into electrical energy through the generator set. Specifically, the resonator C1, connecting rod C2, generator transmission shaft C3, generator gear set C4, generator coil C5, base C6 and other structures together constitute a wave-current generator. The wave-current generator causes the hull to shake up and down through waves, driving the resonator C1 and the hull D2 to rotate relative to each other, and then drives the generator to generate electricity through the generator gear set C4. This design utilizes the high-frequency change characteristics of wave energy, realizes stable energy capture and conversion through the inertia of the resonator, effectively captures wave energy, and enhances the overall energy capture capability. The design of the wave-current generator system can be flexibly adjusted under different wave conditions to ensure efficient power generation.

[0038] The transformer device rectifies the electric energy input by the ocean current generator and the wave current generator, and inputs the electric energy into the land power grid through the submarine cable. The electric energy generated by the ocean current generator and the wave current generator is rectified and regulated by the transformer inside the device to meet the grid standard. The frequency is adjusted to 50Hz so that it can be connected to the national power grid. At the same time, the voltage is increased as much as possible to reduce the loss of electric energy during the transmission process. The regulated electric energy is safely and efficiently transmitted to the land through the cable on the bottom of the ship for use in the city.

[0039] The intelligent control module can use sensors throughout the device to sensitively analyze the environment and ocean current information of the entire device, and control the connection arm group and other parts to adjust so that the device is always in the best working state. The intelligent control device can monitor the marine environment and the operating status of the device in real time. Through sensor data, the position and status of the generator and the connection arm can be automatically adjusted to ensure the best working efficiency under different conditions. The control system also has remote monitoring and maintenance functions. Users can understand the operation of the device in real time through the network and perform remote control.

[0040] The hull device is the backbone of the device and serves to carry other key components. The hull is designed to be sturdy and can work stably in various marine environments. The hull is equipped with an anchoring device E2, which is used to fix the hull to the seabed to ensure the stability and safety of the device in severe sea conditions. The hull also has built-in transformers and control modules for rectification of electrical energy and comprehensive management of the system. The hull design takes into account the adaptability to various marine environments and has good wind and wave resistance. Through structural optimization and material selection, the hull can maintain stability and durability in long-term use. The anchoring device installed on the hull ensures the fixing effect in strong currents and large waves, and is easy to install and disassemble.

[0041] The connecting arm device includes a small arm hydraulic rod B1, a small arm B2, a large arm B3, a fixing part B4, a large arm hydraulic rod B5, a connecting hydraulic rod B6, etc., which are interconnected. The motion control is performed by three hydraulic rods, and the height and position posture of the ocean current generator can be accurately adjusted. The design of the connecting arm takes into account the complexity of the marine environment and can operate flexibly under the combined action of ocean currents and waves. Through the hydraulic system, the connecting arm can be automatically adjusted according to the actual sea conditions to ensure that the generator is always in the best position to capture energy. The connecting arm is precisely controlled by the hydraulic system and can automatically adjust its position according to changes in ocean currents and waves. The design of the hydraulic rod ensures the stability and reliability of the connecting arm at various angles and positions. Through the intelligent control system, the connecting arm can be adjusted in real time to optimize the energy capture efficiency.

[0042] The presence of the mechanical arm enables the device to use the ocean current to drive the propeller to rotate, and transmit the mechanical energy to the generator through the gear set to achieve electrical energy conversion. The relative position of the hydraulic rod is also designed to control the rise and fall of the ocean current generator and its depth in the sea, ensuring that the device will not move excessively during operation and can well meet the diving requirements of the ocean current generator.

[0043] In addition, the ocean current generator is equipped with an automatic adjustment system that can automatically adjust its position and angle according to the direction and speed of the ocean current to ensure the highest energy capture efficiency.

[0044] The design of ocean current generators and wave current generators focuses on efficient energy conversion. The shape of the propeller and resonator is optimized to work efficiently in low-speed ocean currents and high-frequency wave environments. The gear set is manufactured with high precision to ensure efficient and stable power transmission. The generator set uses efficient and durable materials to work for a long time in marine environments.

[0045] This device has the following innovative features: 1. Dual energy capture: the device can capture ocean current energy and wave energy at the same time, making full use of the kinetic energy resources of the ocean. Through the dual power generation system, higher energy utilization efficiency is achieved, greatly increasing power generation.

[0046] 2. Breaking through geographical restrictions, the ocean energy power generation device of the present invention does not rely on specific geographical conditions and can be deployed in any area where there are ocean currents and waves. The device is highly flexible and can adjust its position according to actual needs to adapt to various marine environments.

[0047] 3. Reduce costs. Compared with traditional tidal power stations, the device of the present invention is installed on the hull, which reduces the construction cost of a large amount of infrastructure. Through modular design, the maintenance and upgrade of the device are also more convenient, reducing operating costs.

[0048] 4. Minimum impact on the ecosystem. The device is small in size and has little impact on the ecosystem. Environmental protection requirements are fully considered during the design process. There is no pollution residue after use and it will not cause long-term damage to the natural environment.

[0049] 5. High flexibility and adaptability. The device can automatically adjust its position and posture according to the speed of ocean currents and wave intensity to ensure efficient operation under various ocean conditions. The application of intelligent control system enables the device to optimize the working state in real time to achieve the best power generation efficiency.

[0050] 6. Remote monitoring and automatic maintenance. The power generation device is equipped with an advanced monitoring and maintenance system that can monitor the operating status of the device in real time and perform remote maintenance and management. Users can understand the working status of the device at any time through the network platform, make necessary adjustments and maintenance, and improve the reliability and service life of the system.

[0051] The specific working principle and working process of this device are as follows: The device is equipped with an advanced control module D5 (including a sensor system) that can monitor the speed, direction and other marine environmental data of the ocean current in real time. These data are processed by a computer to generate a detailed status report for reference by the control center and the regulation system. When the kinetic energy of the ocean current is small, the system can enter a self-maintenance mode, such as adjusting the mechanical arm and cleaning the propeller. When the kinetic energy of the ocean current is too large, the system will automatically adjust the direction of the blade A3 to avoid damage to the ocean current generator. As the backbone of the device, the hull D2 fixes the ocean current generator and the wave current generator, and includes key components such as the transformer and the control module. The connecting arm is extended and retracted through a hydraulic rod to control the rise and fall and position and posture adjustment of the ocean current generator to ensure that the generator is always in the best working position.

[0052] First, the device will be transported to a place where ocean energy is relatively abundant by large transportation vehicles and properly placed. The anchor E2 will be lowered by the chain E1 to anchor the device in the area. Then the control module D5 in the device will monitor the ocean current speed, direction and other marine environmental data to determine the best power generation location and depth. At this time, the boom hydraulic rod B5 will control the boom B3 to move downward to the appropriate position, and the arm hydraulic rod B1 will control the arm B2 to adjust the diving depth of the ocean current generator. After the mechanical claw adjusts the position of the ocean current generator, the ocean current will drive the fan blade A3 to rotate, and the rotating mechanical energy will be transmitted to the generator gear set C4 through the gear set to make the generator coil C5 generate electricity. At the same time, in areas rich in ocean energy, the waves will be relatively large, and the waves will cause the hull to shake up and down, driving the resonator C1 and the hull D2 to rotate relative to each other, and then driving the generator to generate electricity through the generator gear set C4. Finally, the power transmission line C7 of the two generators is integrated into the transmission pipeline D1 and transported to the transformer room D4 to enter the transformer, and the voltage is increased and transported to the land through the transformer bushing F1.
