Description

Technical Field

[0001] This invention relates to the field of offshore wind power technology, and more particularly to a floating offshore wind power system with available flow loads. Background Technology

[0002] Floating wind power platforms are deployed in the open ocean, where environmental conditions are more severe than in nearshore areas. Due to higher wind and current speeds, the platforms experience greater current loads, accompanied by swaying motion. This reduces the power generation efficiency of the wind turbines and can lead to vortex-induced vibrations, making the structures more susceptible to fatigue and posing safety hazards. Furthermore, the floating platforms of floating wind power equipment are currently expensive, and the loss of current loads is not being maximized. Therefore, we propose a floating offshore wind power system that utilizes current loads. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a floating offshore wind power system that can utilize flow loads.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A floating offshore wind turbine with available flow load includes a float plate. Four diverter cylinders are arranged circumferentially around the center of the lower side of the float plate. An impeller assembly is arranged at the junction of the four diverter cylinders. A generator is arranged on one side of the impeller assembly. A potential energy conversion assembly is arranged on the upper side of the float plate to convert potential energy into electrical energy for storage.

[0006] Preferably, the potential energy conversion component includes a current load power generation conversion module, which is disposed on the upper side of the float. The generator and the current load power generation conversion module are electrically connected via wires. A current load power generation energy storage module is disposed on the upper side of the float, and the current load power generation energy storage module and the current load power generation conversion module are electrically connected via wires.

[0007] The above technical solution involves placing a floating plate with four diversion tubes below sea level. Utilizing the current load of ocean waves, the current load impacts the impeller assembly through the diversion tubes, causing the impeller assembly to rotate and provide a rotational power supply to the generator. Simultaneously, the potential energy of the current load is converted by the impeller assembly and the generator through the current load power generation conversion module and stored in the current load power generation storage module, providing a usable function for the current load.

[0008] Preferably, a wind power generation component is provided at the upper center of the floating plate, and a wind power conversion module is provided on the upper side of the floating plate. The wind power generation component and the wind power conversion module are electrically connected by wires, and a wind power energy storage module is electrically connected to one side of the wind power conversion module by wires.

[0009] Through the above technical solution, the wind power generation component is blown by the wind and generates wind energy. The wind energy is converted into electrical energy by the wind power conversion module, and the electrical energy is then stored by the wind power energy storage module, thereby providing a wind power generation function.

[0010] Preferably, a connecting frame is provided on one side of the float plate, a bidirectional cylinder is provided at the bottom of one side of the connecting frame, a connecting plate is provided at the shaft end of the bidirectional cylinder, a protruding plate is provided on one side of the connecting plate, a baffle is provided on one side of the protruding plate, and a flow sensor is provided on one side of the baffle.

[0011] Through the above technical solution, the diversion tube is below sea level and is impacted by the sea waves. The flow sensor detects the flow rate. When the flow rate is high, the flow sensor sends a signal to the bidirectional cylinder. The bidirectional cylinder controls the connecting plate to move, and the connecting plate drives the convex plate to move. The convex plate causes the baffle to detach from the diversion tube, so that the two diversion tubes form an unobstructed path. This facilitates the impact of the sea waves on the impeller assembly inside the diversion tube, avoiding the uneven force on the internal impeller assembly when all four diversion tubes are open at the same time. At the same time, the flow rate of the four inlets can also be controlled.

[0012] Preferably, a number of floats are provided on the lower side of the float plate, and the floats are positioned between the two diversion tubes.

[0013] Through the above technical solution, the buoy can provide a certain buoyancy sharing function for the float plate.

[0014] Preferably, the diversion tube is configured in a trumpet shape, and a single-point mooring structure is provided on the lower side of the diversion tube.

[0015] Through the above technical solution, when the flow velocity passes through the funnel-shaped structure of the diversion tube, the flow load can cause the diversion tube to automatically generate a yaw effect, so that the funnel opening faces the flow direction.

[0016] Preferably, a circular filter plate is snapped onto one side of the flow guide tube, and a flow guide groove is provided on the inner side of the circular filter plate.

[0017] Through the above technical solution, the circular filter plate can provide a filtering function for the drainage cylinder, preventing objects from entering the drainage cylinder.

[0018] Preferably, a guide rod is provided on the lower side of the float, an A sinking plate is provided on the lower side of the guide rod, a grid is provided on the lower side of the A sinking plate, a B sinking plate is provided on the lower side of the grid, a sonar generator is provided at the upper center of the B sinking plate, and several lead blocks are provided at the upper edge of the B sinking plate.

[0019] Through the above technical solution, the A sinking plate, together with the B sinking plate, can provide a certain sinking force to the float, preventing the float from being too light and shifting in position due to wind. The sonar generator can disturb nearby marine life, preventing marine life from colliding with the float and causing damage. The grid provides a protective function for the sonar generator.

[0020] The floating offshore wind power system proposed in this invention, which utilizes flow loads, has the following advantages:

[0021] This invention places a floating plate with four diversion tubes below the sea level. Utilizing the current load of ocean waves, the current load impacts the impeller assembly through the diversion tubes. The impeller assembly rotates, providing a rotational power supply to the generator. At the same time, the potential energy of the current load is converted by the impeller assembly and the generator through the current load power generation conversion module and stored in the current load power generation storage module, providing a usable function for the current load.

[0022] In this invention, the diversion tube is below sea level and is impacted by ocean waves. A flow sensor detects the flow rate. When the flow rate is high, the flow sensor sends a signal to a bidirectional cylinder. The bidirectional cylinder controls the movement of a connecting plate, which in turn moves a convex plate. The convex plate causes the baffle to detach from the diversion tube, creating a clear path between the two diversion tubes. This facilitates the impact of ocean waves on the impeller assembly inside the diversion tube, preventing uneven force on the internal impeller assembly when all four diversion tubes are open. Furthermore, the flow rate can be controlled at all four inlets.

[0023] In this invention, sinking plate A, together with sinking plate B, can provide a certain sinking force to the float, preventing the float from being too light and shifting in position due to wind. The sonar generator can disturb nearby marine life, preventing marine life from colliding with the float and causing damage. The grid provides a protective function for the sonar generator.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] like Figure 1-3 As shown, a floating offshore wind power system capable of utilizing current loads includes a float 1. A wind power generation component 3 is disposed at the upper center of the float 1, and a wind power conversion module 6 is disposed on the upper side of the float 1. The wind power generation component 3 and the wind power conversion module 6 are electrically connected via wires. A wind power energy storage module 5 is electrically connected to one side of the wind power conversion module 6 via wires.

[0030] Four diversion cylinders 2 are installed on the lower side of the float plate 1. The diversion cylinders 2 are arranged in a trumpet shape. A single-point mooring structure is installed on the lower side of the diversion cylinders 2. The four diversion cylinders 2 are evenly distributed in a circle around the center of the lower side of the float plate 1. Several buoys 15 are installed on the lower side of the float plate 1, and the buoys 15 are located between two diversion cylinders 2. An impeller assembly 4 is installed at the junction of the four diversion cylinders 2. A generator is installed on one side of the impeller assembly 4. A current load power generation conversion module 8 is installed on the upper side of the float plate 1. The generator and the current load power generation conversion module are electrically connected by wires. A current load power generation energy storage module 7 is installed on the upper side of the float plate 1. The current load power generation energy storage module 7 is electrically connected to the current load power generation conversion module by wires.

[0031] A connecting frame 9 is provided on one side of the float plate 1. A two-way cylinder 10 is provided at the bottom of one side of the connecting frame 9. A connecting plate 11 is provided at the shaft end of the two-way cylinder 10. A protruding plate 12 is provided on one side of the connecting plate 11. A baffle 13 is provided on one side of the protruding plate 12. A flow sensor 14 is provided on one side of the baffle 13. A circular filter plate 16 is snap-connected to one side of the flow guide tube 2. A flow guide groove is provided on the inner side of the circular filter plate 16.

[0032] A guide rod 17 is provided on the lower side of the float 1. A sinking plate A 18 is provided on the lower side of the guide rod 17. A grid 19 is provided on the lower side of the sinking plate A 18. A sinking plate B 20 is provided on the lower side of the grid 19. A sonar generator 21 is provided at the upper center of the sinking plate B 20. Several lead blocks 22 are provided at the upper edge of the sinking plate B 20.

[0033] In this embodiment, a floating plate 1 with four diversion tubes 2 is placed below the sea level. Utilizing the current load of the ocean waves, the current load impacts the impeller assembly 4 through the diversion tubes 2, causing the impeller assembly 4 to rotate and provide a rotational power supply to the generator. Simultaneously, the potential energy of the current load is converted by the impeller assembly 4 and the generator through the current load power generation conversion module 8 and stored in the current load power generation storage module 7. The wind power generation component 3 is blown by the wind and generates wind energy, which is converted into electrical energy through the wind power generation conversion module 6. The electrical energy is then stored in the wind power generation storage module 5, allowing multiple energies to be stored and used simultaneously.

[0034] In this embodiment, the diversion tube 2 is below sea level and is impacted by waves. The flow sensor 14 detects the flow rate. When the flow rate is high, the flow sensor 14 sends a signal to the bidirectional cylinder 10. The bidirectional cylinder 10 controls the connecting plate 11 to move, which in turn moves the convex plate 12. The convex plate 12 causes the baffle 13 to detach from the diversion tube 2, creating a clear path between the two diversion tubes 2. This facilitates the impact of waves on the impeller assembly 4 inside the diversion tube 2, preventing uneven force on the internal impeller assembly 4 when all four diversion tubes 2 are open simultaneously.

[0035] At the same time, the flow rate of the four inlets can be controlled. When the flow velocity passes through the funnel-shaped structure of the diversion tube 2, the flow load can make the diversion tube 2 automatically generate a yaw effect, so that the funnel mouth faces the flow direction.

[0036] In this embodiment, the sinking plate A 18, together with the sinking plate B 20, can provide a certain sinking force to the float 1, preventing the float 1 from being too light and shifting in position due to wind. The sonar generator 21 can disturb nearby marine life, preventing marine life from colliding with the float 1 and causing damage. The grid 19 protects the sonar generator 21.

[0037] Single-point mooring structure: A single-point mooring terminal typically consists of a buoy that floats on the sea surface and pipelines laid on the seabed connecting to the onshore storage system. The buoy floats on the sea surface, and crude oil from the tanker enters the buoy through a floating hose, then flows through an underwater hose into the subsea pipeline, eventually reaching the crude oil storage tanks on shore. To prevent the buoy from drifting long distances with the waves, it is connected to the seabed by several large anchor chains. This allows the buoy to float and move within a certain range with the wind, waves, and currents, increasing its cushioning effect and reducing the risk of collisions with large vessels, while preventing it from being swept away by the waves.

[0038] Sonar Generator 21: Because electromagnetic waves attenuate at a very high rate in water, they cannot be used as a signal source for detection. Therefore, using sound waves to detect man-made objects underwater has become the most widely used method. Both submarines and surface ships utilize derivative systems of this technology to detect underwater objects or as a navigational aid. Sonar technology, a technology for detecting underwater targets, was thus developed.
