Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, and more specifically to a kite-type generator. Background Technology

[0002] The importance of energy to the national economy is self-evident. With rapid economic development, society's demand for energy is constantly increasing, while the reserves of non-renewable energy sources such as oil and natural gas are decreasing day by day. Countries around the world are seeking green and renewable new energy sources. In recent years, scientists have turned their attention to the ocean, believing that it is a treasure trove of resources for the earth, and that tidal and ocean current energy will be utilized on a large scale with technological advancements.

[0003] Currently, the utilization of tidal energy is mainly based on tidal power stations. There are also kite generators, but kite generators only use one rudder to control the trajectory, which results in fewer controllable degrees of freedom and low power generation efficiency. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the existing kite generator, which uses a single rudder to control the trajectory of motion and has fewer controllable degrees of freedom, resulting in low power generation efficiency, and thus provides a kite generator.

[0005] To address the above problems, the present invention provides a kite-type generator, comprising:

[0006] The airframe includes a main cabin and main wings symmetrically arranged on both sides of the main cabin. Each main wing is provided with a side cabin. The main cabin is provided with a controller. The airframe is adapted to be placed below the sea level.

[0007] A turbine generator is located at the rear of the main engine compartment;

[0008] At least two blade structures are provided, which are symmetrically arranged at the tail of the side nacelles on both sides of the main engine nacelle. The blade structures are rotatably connected to the side nacelles. Each blade structure is provided with a vertical blade and a horizontal blade. The controller controls the pitch angle of the vertical blade and / or the horizontal blade to control the force direction and torque of the body, so that the turbine generator can rotate and generate electricity.

[0009] Optionally, it also includes a side wing, which is located on the side of the side cabin away from the main cabin, and the main wing is integrally formed with the side cabin.

[0010] Optionally, the side wing and the side cabin are set at an acute angle.

[0011] Optionally, the main unit compartment is equipped with a depth gauge, a power supply, and a gearbox. The gearbox is rotatably connected to a turbine generator, the turbine generator is connected to a power supply line, and the depth gauge, generator, and gearbox are respectively communicatively connected to a controller.

[0012] Optionally, each of the vertical blades is connected to a vertical power unit, and each of the horizontal blades is connected to a horizontal power unit. The vertical and horizontal power units are located in the side nacelle, and the vertical and horizontal power units are respectively connected to power lines.

[0013] Optionally, each of the side nacelles is further provided with a vertical blade angle sensor and a horizontal blade angle sensor, which are respectively connected to the controller.

[0014] Optionally, it also includes a mooring base and armored cables, the mooring base being placed on the seabed surface, and the armored cables connecting the hull to the mooring base.

[0015] Optionally, it also includes a submarine cable connected to the mooring foundation.

[0016] The technical solution of this invention has the following advantages:

[0017] 1. The kite-shaped generator provided by this invention includes: a fuselage, comprising a main nacelle and main wings symmetrically arranged on both sides of the main nacelle, each main wing having a side nacelle, and a controller disposed within the main nacelle; a turbine generator disposed at the tail of the main nacelle; and at least two blade structures symmetrically arranged at the tail of the side nacelles on both sides of the main nacelle, the blade structures being rotatably connected to the side nacelles, each blade structure having a vertical blade and a horizontal blade, the controller controlling the pitch angle of the vertical blade and / or the horizontal blade to control the force direction and torque of the fuselage, thereby causing the turbine generator to rotate and generate electricity. By controlling the blade structures on both sides of the main nacelle, i.e., by controlling the pitch angle of the two vertical blades and the two horizontal blades, the overall force on the fuselage is controlled, thereby adjusting the movement trajectory of the fuselage to move along the direction of the ocean currents. Furthermore, the four blades control the force and torque in multiple directions of the fuselage, making the control of the fuselage's movement trajectory more precise and rapid. The turbine generator maximizes the use of tides for power generation, achieving high-efficiency power generation.

[0018] 2. The kite-shaped generator provided by this invention also includes side wings, which are located on the side of the side nacelle away from the main nacelle. The main wing and the side nacelle are integrally formed. The addition of side wings can effectively reduce the intensity of vortices at the wingtips of the main wing, reduce the induced drag of the overall wing, and improve the lift-to-drag ratio. The integral formation of the side nacelle and the main wing effectively reduces the number of structural components, making the overall design simpler, more compact, and more stable.

[0019] 3. The kite-shaped generator provided by the present invention has an acute angle between the side wing and the side nacelle to improve the overall aerodynamic performance of the fuselage.

[0020] 4. The kite-type generator provided by this invention includes a depth gauge, a power supply, and a gearbox inside the main engine compartment. The gearbox is rotatably connected to a turbine generator, which is connected to the power supply line. The depth gauge, generator, and gearbox are all communicatively connected to a controller. The depth gauge in the main engine compartment measures the depth of the machine body in real time and feeds it back to the controller. The electricity generated by the turbine generator driving the gearbox to rotate is stored in the power supply, which provides power to the machine body.

[0021] 5. The kite-type generator provided by the present invention has a vertical power component connected to each vertical blade and a horizontal power component connected to each horizontal blade. The vertical and horizontal power components are located in the side nacelle and are respectively connected to the power supply line. The power supply drives the vertical power component to rotate the vertical blade and drives the horizontal power component to rotate the horizontal blade. The movement trajectory and angle of the generator are adjusted by the rotation of the vertical and horizontal blades.

[0022] 6. The kite-type generator provided by the present invention has a vertical blade angle sensor and a horizontal blade angle sensor in each side nacelle. The vertical blade angle sensor and the horizontal blade angle sensor are respectively connected to the controller to transmit the angle of the vertical blade and the angle of the horizontal blade to the controller in real time.

[0023] 7. The kite-type generator provided by the present invention also includes a mooring base and an armored cable. The mooring base is placed on the seabed surface, and the armored cable is connected between the generator body and the mooring base so that the generator body can rotate around the mooring base.

[0024] 8. The kite-type generator provided by the present invention also includes a submarine cable, which is connected to the mooring foundation to transmit excess energy in the power source via the armored cable and the submarine cable. Attached Figure Description

[0037] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Example 1

[0039] The kite-type generator provided by the present invention includes: a body 1, the body 1 including a main nacelle and main wings 2 symmetrically arranged on both sides of the main nacelle, each main wing 2 having a side nacelle, and a controller being provided in the main nacelle; the body 1 being adapted to be placed below sea level 11; a turbine generator 3 being located at the tail of the main nacelle; and at least two blade structures, the blade structures being symmetrically arranged at the tail of the side nacelles on both sides of the main nacelle, the blade structures being rotatably connected to the side nacelles, each blade structure having a vertical blade 4 and a horizontal blade 7, the controller controlling the pitch angle of the vertical blade 4 and the horizontal blade 7 to control the force direction and torque of the body 1, so that the turbine generator 3 rotates to generate electricity. By controlling the propeller structures on both sides of the main engine compartment, that is, by controlling the pitch angle of the two vertical propellers 4 and the two horizontal propellers 7, the overall force on the body 1 is controlled, so as to adjust the motion trajectory of the body 1 and make the body 1 move along the direction of the ocean current. Then, the four propellers control the force and torque on the body 1 in multiple directions, making the control of the motion trajectory of the body 1 more precise and faster. The turbine generator 3 utilizes the tide to generate electricity to the greatest extent and achieves high-efficiency power generation.

[0040] Example 2

[0041] like Figure 1 A specific embodiment of a kite-type generator shown in Figure 7 includes: a body 1 located below sea level 11, the body 1 having a main cabin, main wings 2 on both sides of the main cabin, and each main wing 2 having an integrally formed side cabin to reduce the number of structural components, making the overall design simpler, more compact and stable.

[0042] like Figure 1 , Figure 2 , Figure 3As shown, a turbine generator 3 is located at the tail of the main engine compartment of fuselage 1. A gearbox is installed within the main engine compartment to connect the turbine generator 3 to it. A power supply is located within the main engine compartment to store the electricity generated by the turbine generator 3. A depth gauge and a controller are installed within the main engine compartment to measure the depth of fuselage 1. The controller is connected to the depth gauge, the power supply, and the turbine generator 3 wiring. To improve the lift-to-drag ratio, a side wing 5 is located on the side of each fuselage compartment furthest from the main engine compartment, with an acute angle between the side wing 5 and the side fuselage compartment. A side fuselage cover is located at the side wing 5. Specifically, the surface material of the main wing 2 and the side wing 5 is fiberglass, the internal supporting components are made of carbon fiber composite material, and the internal space of the wing is filled with foam material.

[0043] To adjust the trajectory of the fuselage 1, each side nacelle 6 has a propeller structure at its tail, and each propeller structure has a vertical blade 4 and a horizontal blade 7. To drive the propeller rotation, vertical and horizontal power components are also included within the side nacelles 6. Each vertical blade 4 is connected to a vertical power component, and each horizontal blade 7 is connected to a horizontal power component. The vertical and horizontal power components are communicatively connected to a controller, and power is provided to both components. Specifically, both the vertical and horizontal power components are servo motors. To measure the blade angle, each side nacelle 6 also has a vertical blade 4 angle sensor and a horizontal blade 7 angle sensor, which are communicatively connected to the controller.

[0044] like Figure 1 , Figure 4 As shown, a mooring base 9 is placed on the seabed 12. An armored cable 8 connects the main body 1 to the mooring base 9, and a submarine cable 10 is connected to the mooring base 9. The mooring base 9 is equipped with an angle sensor for the armored cable 8. The armored cable 8 contains an output cable and a signal cable. The output cable is used to output the power generated by the turbine generator 3, and the signal cable is used to transmit the information from the angle sensor of the armored cable 8 to the controller. It should be noted that the cable shell of the armored cable 8 is made of rubber composite material.

[0045] In practice, the turbine generator 3 draws mechanical energy from the ocean currents and converts this mechanical energy into electrical energy by driving the turbine generator 3 to rotate at high speed through a gearbox. Part of the electrical energy generated by the turbine generator 3 is output through the output cable in the armored cable 8, and part is used to charge the power supply in the main engine room. The power supply provides power to the depth gauge, controller, vertical blade 4 angle sensor, horizontal blade 7 angle sensor in the side engine room 6, vertical power unit, and horizontal power unit. The controller sends control commands to the vertical and horizontal power units. The vertical power unit drives the vertical blade 4 to swing, and the horizontal power unit drives the horizontal blade 7 to swing, thereby controlling the direction of movement of the aircraft 1. The vertical blade 4 angle sensor, horizontal blade 7 angle sensor, and armored cable 8 angle sensor transmit the measured angle parameters to the controller, and the depth gauge transmits the measured depth parameters to the controller. It should be noted that in the event of a malfunction in the aircraft 1, the turbine generator 3 can be powered by the power supply and transformed into an engine to drive the aircraft 1 to the surface for maintenance.

[0046] During the actual measurement process, the armored cable 8 measures the tilt angle α and rotation angle β, and the rotation angles of the four propellers are transmitted to the controller. The tilt angle α is the angle between the armored cable 8 and the horizontal plane, and the rotation angle β is the angle between the armored cable 8 and the horizontal component of the incoming flow. The tilt angle α and rotation angle β can be used together to calculate the position, speed, and direction of the aircraft 1. The controller analyzes the tilt angle α and rotation angle β to determine the required deflection angle for each propeller. Then, the power component connected to the propeller drives the propeller to deflect, changing the force on the propeller and thus altering the overall force on the aircraft 1, ensuring that the aircraft 1 moves along its trajectory. It is important to note that because the armored cable 8 experiences significant force during the movement of the aircraft 1, it has almost no bending and can be considered approximately a straight rod, and it does not rotate or displace relative to the aircraft 1.

[0047] like Figure 5 As shown, the blades are subjected to forces during motion. The horizontal blade 7 is parallel to the main wing 2. Increasing the pitch angle of the horizontal blade 7 increases the lift F of the horizontal blade 7 in the direction perpendicular to the main wing 2. L This causes body 1 to move in a square along the y-axis; for example... Figure 6 As shown, when the two horizontal blades 7 rotate in different directions, the lift force F acting on the two horizontal blades 7 is... L In the opposite direction, body 1 rotates along the x-axis; such as Figure 7 As shown, the vertical blade 4 is perpendicular to the axial direction of the main wing 2 and the main nacelle. When the two vertical blades 4 rotate in a square shape along the y-axis, they will increase the lift F of the vertical blades 4 along the positive z-axis. L The body 1 moves along the positive z-axis.

[0048] As an alternative implementation, the side wing 5 and the main wing 2 are set at an acute angle.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
