Abstract
Description
paddlewheel ocean current turbine unit This invention relates to the field of turbine devices for power generation, and specifically to a paddlewheel ocean current turbine unit with a downward-sinking design to avoid typhoons. Taiwan's energy needs are primarily met by imported non-renewable energy sources. In line with the government's energy transition policy aimed at achieving net-zero carbon emissions by 2050, efforts are being made to increase the proportion of renewable energy in electricity generation. Renewable energy includes ocean energy, which in turn includes ocean current energy. The world's second-largest ocean current flows through the waters east of Taiwan. Ocean currents are clean and green energy sources, and their flow speed and direction are very stable. Just as wind turbines generate electricity using a fixed wind direction, ocean currents can also power paddlewheel generators using a fixed flow direction. According to domestic surveys, ocean currents in the waters near Turtle Island, Hualien, Green Island, and Orchid Island could provide 4GW of green energy for power generation. Increasing the proportion of renewable energy has been a globally promoted policy. The reason why ocean current power generation has not yet been commercially successful is due to numerous factors, including the marine environment and the efficiency of power generation systems, which have prevented it from achieving sufficiently low power generation costs and sufficiently stable power generation efficiency. A careful study of previous ocean energy turbine generator technologies reveals that the equipment is too large, making it difficult to place upright and face ocean currents. Furthermore, the turbine generators are susceptible to damage from seawater erosion and typhoon waves, resulting in high costs and impacts on the marine ecosystem. How to solve the above problems is a topic that relevant businesses are actively addressing. The main objective of this invention is to provide a submersible paddlewheel ocean current turbine unit that can avoid typhoons. This unit utilizes ocean current energy to extract energy and convert it into electricity. The turbine unit is installed in the ocean current, and the kinetic energy generated by the current drives the paddlewheel, which in turn drives generators on both sides. Optimizations to the paddlewheel blades enable stable smooth rotation in ocean currents, achieving a power generation efficiency of up to 25%. Furthermore, the paddlewheel ocean current turbine generator unit has advantages such as low manufacturing cost, simple structure, convenient installation and maintenance, and the ability to be submerged to avoid typhoons, minimizing impact on the marine environment and ecology. Due to the continuity and directionality of ocean currents, the power output is relatively stable. As an important component of ocean energy, ocean current power generation has the potential to operate in all weather conditions. Simply placing the paddlewheel ocean current turbine in the ocean current provides stable and high-efficiency power generation. Therefore, the structure of the present invention includes: A frame having an assembly section formed on both sides, the frame having a drain end and a drain end; A paddle wheel, mounted on the assembly section formed by the frame, the paddle wheel having a paddle wheel torque, three paddle wheel blades arranged on the paddle wheel torque, and a flange-type coupling disc on each side of the paddle wheel torque; and At least one generator is mounted on the outside of the frame and is shaft-connected to the flange-type coupling disc, and a water-sealing box is fitted on the outside of the generator; The ocean current is introduced through the inlet end of the frame to drive the paddle wheel to rotate. The paddle wheel drives the generator to rotate through the flange-type coupling discs at both ends to generate electricity. The ocean current is discharged from the outlet end, and the generator also outputs the generated electricity through a power grid. In an embodiment of the present invention, the frame is mounted on an iron frame, which is fixed to a seabed. In an embodiment of the present invention, the frame is provided with multiple sets of floats around the assembly section, and a cable is provided from the assembly section toward the diversion end. Another set of floats is installed on the cable. The aforementioned cable is connected to the seabed after being combined with nylon rope and iron chain, so that the frame can float in the sea and drive the paddle wheel to rotate and generate electricity through ocean current. In an embodiment of the present invention, the paddle wheel is manufactured using a photocurable material. In an embodiment of the invention, the floats are connected to the frame via semi-tensioned cables. Based on the above description, the features and effects of the present invention are briefly summarized as follows: 1. This invention utilizes ocean current energy to extract energy and convert it into electrical energy. The generator unit is installed in the ocean current, and the kinetic energy generated by the current drives a paddle wheel, which in turn drives generators on both sides to generate electricity through electromagnetic induction. Because this invention is small in size and low in cost, it is easy to construct in the waters near Taiwan. 2. Improvements to the paddle wheel blades enable the turbine generator set to rotate stably in water, achieving a power generation efficiency of 25%. It also boasts lower manufacturing costs, a simpler structure, convenient installation and maintenance, and the ability to be submerged to typhoon-avoidance depth. As shown in Figures 1 and 2, the paddlewheel ocean current turbine unit of the present invention comprises: a frame 10, a paddlewheel 20, and two generators 30. As shown in Figures 1 and 2, the frame 10 has an assembly section 11 on both sides, and the frame 10 has a drain end 12 and a drain end 13. As shown in Figures 1 to 4, the paddle wheel 20 is mounted on the assembly section 11 formed by the frame 10. The paddle wheel 20 has a paddle wheel torque 21, on which three paddle wheel blades 22 are arranged, and a flange-type coupling disc 23 is provided on both sides of the paddle wheel torque 21. In addition, the paddle wheel 20 is manufactured using a photocurable material. As shown in Figures 1 to 3, the generator 30 is located on the outside of the frame 10 and is engaged with the flange-type coupling plate 23. A water-sealing box 31 is fitted on the outside of the generator 30. As shown in Figures 1, 3, and 4, during use, the ocean current is introduced through the inlet end 12 of the frame 10 to drive the paddle wheel 20 to rotate. The paddle wheel 20 drives the generators 30 to rotate through the flange-type coupling discs 23 at both ends to generate electrical energy. The ocean current is discharged from the outlet end 13, and the generator 30 also outputs the generated electrical energy through a power grid (not shown in the figure). As shown in Figure 5, specifically, the present invention can mount the frame 10 on an iron frame 40 and mount the iron frame 40 on the seabed 50. Therefore, through this embodiment, the generator set can be installed in a sea area with stable ocean currents to generate electricity. As shown in Figure 6, when the sea area is unsuitable for erecting the iron frame 40 on the seabed 50, the frame 10 can be equipped with multiple sets of buoys 60 around the assembly section 11. A cable 61 is installed from the assembly section 11 towards the diversion end 12, and another set of buoys 62 is installed on the cable 61. The aforementioned cable 61 is connected to the seabed 50 after being combined with nylon rope and iron chain, so that the frame 10 can float in the sea and drive the paddle wheel 20 to generate electricity through ocean currents. Normally, the generator set can generate electricity normally. When typhoons and waves occur, the generator set can extend the length of the cable attached to the buoys to submerge the frame 10, preventing the cable 61 from breaking due to wind and waves. Furthermore, the cable 61 between the buoys 60 and the frame 10 is a semi-tensioned cable 61, which allows the frame 10 to float in the sea and generate electricity. It can be understood that this invention utilizes ocean current energy to extract energy and converts the extracted energy into electrical energy. The unit is installed in the ocean current, and the kinetic energy generated by the current drives the paddle wheel 20, which in turn drives the generators 30 on both sides to generate electricity through electromagnetic induction. Because this invention is small in size and low in cost, it is easy to build in the waters near Taiwan. In addition, improvements to the paddle wheel blades 22 enable the turbine generator set to rotate stably in water, achieving a power generation efficiency of 25%, while also having lower manufacturing costs, a simpler structure, convenient installation and maintenance, and the ability to submerge the unit to a depth that avoids typhoons. To achieve typhoon avoidance, the cable 61 can be wound up to submerge the invention to a depth where the ocean current speed is below 20 cm / s. At the aforementioned ocean current speed, the frame 10, paddle wheel 20, and generator 30 of the invention will not move, thus preventing equipment damage. It should be noted that the above description is a specific embodiment of the present invention and the technical principles used. Any changes made according to the concept of the present invention, if the resulting functions do not exceed the spirit covered by the specification and drawings, should be within the scope of the present invention and are hereby stated. 10: Frame 11: Assembly Section 12: Drainage End 13: Drainage End 20: Paddlewheel 21: Paddlewheel Torque 22: Paddlewheel Blades 23: Flange-type Coupling Disc 30: Generator 31: Watertight Box 40: Iron Frame 50: Seabed 60: Buoy 61: Cable 62: Buoy Figure 1: Structural diagram of the present invention.
