Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, and in particular to a device for converting wave energy, wind energy, and ocean current energy. Background Technology

[0002] my country has a vast coastline, and the ocean provides natural and renewable clean energy sources such as tidal energy, wave energy, wind energy, and thermal energy. The development of clean energy is not yet fully realized by countries worldwide, and one crucial source is ocean wave energy and ocean current energy. Generating electricity using wave and ocean current energy is not only time-consuming but also doesn't require land, making it a very promising clean energy source. Therefore, how to simply and efficiently utilize ocean energy is a pressing issue for the applicant. Summary of the Invention

[0003] The purpose of this invention is to provide a device for converting wave energy, wind energy, and ocean current energy. This invention can effectively convert wave energy, ocean current energy, and wind energy into electrical energy, and has the advantages of simple structure and high conversion efficiency.

[0004] The technical solution of this invention: A wave energy, wind energy, and ocean current energy conversion device includes a base frame, a first outer shell, a second outer shell, a damping generator, a rotary generator, and a turbine generator. The second outer shell is located inside the first outer shell, and the space between the first and second outer shells forms an outer air chamber. The interior space of the second outer shell forms an inner air chamber. A ventilation duct connected to the turbine generator is provided between the first and second outer shells. A sleeve is provided in the middle of the base frame, and the rotary generator is placed in the sleeve. A rotating shaft connected to the rotary generator is provided in the middle of the sleeve, and a first thrust plate and a second thrust plate are provided on the rotating shaft. The damping generator is respectively built into the first thrust plate and the second thrust plate. A first piston that cooperates with the corresponding damping generator is provided in the first thrust plate, and a first float is provided at the top of the first piston. The first float is located in the outer air chamber. A second piston that cooperates with the corresponding damping generator is provided in the second thrust plate, and a second float is provided at the top of the second piston. The second float is located in the inner air chamber.

[0005] In the aforementioned wave energy, wind energy, and ocean current energy conversion device, the first and second propeller plates are staggered, and the included angle between the first and second propeller plates is 30-60°.

[0006] The aforementioned wave energy, wind energy and ocean current energy conversion device has two of each: the first propeller plate and the second propeller plate.

[0007] In the aforementioned wave energy, wind energy and ocean current energy conversion device, a first counterweight is provided above the first float.

[0008] The aforementioned wave energy, wind energy and ocean current energy conversion device has a second counterweight above the second float.

[0009] The aforementioned wave energy, wind energy, and ocean current energy conversion device has a first outer shell and a second outer shell that are hemispherical in shape.

[0010] The aforementioned wave energy, wind energy, and ocean current energy conversion device has an annular groove at the top end of the sleeve, an I-shaped rotating block inside the annular groove, a traction power generation device in the middle of the rotating block, a pull rope wound around the traction power generation device, and the two ends of the pull rope being connected to the corresponding second counterweight block.

[0011] Compared with existing technologies, this invention utilizes the characteristic of the first and second floats rising and falling with the waves to drive the first and second pistons to move relative to the damping generator. This allows the damping generator to generate electricity under the action of the first and second pistons. Furthermore, the up-and-down movement of the second piston causes the gas in the inner chamber to periodically compress and expand with the waves, which in turn drives the turbine generator through the ventilation duct to generate electricity. Simultaneously, the ocean current below the surface impacts the first and second thrusters, which drive the rotating shaft. The rotation of the shaft causes the rotary generator inside the casing to generate electricity. Thus, this invention utilizes wave energy, compressed air energy (wind energy), and ocean current energy for power generation, offering advantages such as simple structure and high energy efficiency. In addition, the second float, as it rises and falls, can also pull a rope to activate the traction generator, further improving energy utilization. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example: A device for converting wave energy, wind energy, and ocean current energy, such as... Figure 1-2As shown, it includes a base frame 1, a first outer shell 2, a second outer shell 3, a damping generator 4 (a device that can convert the energy of vibration and up-and-down work into electrical energy), a rotary generator 5, and a turbine generator 6. Both the rotary generator 5 and the turbine generator 6 generate electricity by cutting magnetic field lines in a rotating manner. The second outer shell 3 is located inside the first outer shell 2, and the first outer shell 2 and the second outer shell 3 are hemispherical. The space between the first outer shell 2 and the second outer shell 3 forms an outer air chamber 7, and the internal space of the second outer shell 3 forms an inner air chamber 8; a ventilation duct 9 connected to the turbine generator 6 is provided between the first outer shell 2 and the second outer shell 3; a sleeve 10 is provided in the middle of the base frame 1, and a rotary generator 5 is placed in the sleeve 10; a rotating shaft 11 connected to the rotary generator 5 is provided in the middle of the sleeve 10, and a first thruster plate 12 and a second thruster plate 13 are provided on the rotating shaft 11; the first thruster plate 12 and the second thruster plate 13 are staggered, and the included angle formed by the first thruster plate 12 and the second thruster plate 13 is 45° or 30°, and there are two of each of the first thruster plate 12 and the second thruster plate 13. The damping generators 4 are respectively built into the first thrust plate 12 and the second thrust plate 13. The first thrust plate 12 has a first piston 14 that cooperates with the corresponding damping generator 4. The first piston 14 performs work on the damping generator 4 by pressing down and floating up. A first float 15 is located at the top of the first piston 14, within the outer air chamber 7. A first counterweight 18 is located above the first float 15, providing downward pressure to the first piston 14. The second thrust plate 13 has a second piston 16 that cooperates with the corresponding damping generator 4. The second piston 16 performs work on the damping generator 4 by pressing down and floating up. A second float 17 is located at the top of the second piston 16, within the inner air chamber 8. A second counterweight 19 is located above the second float 17, providing downward pressure to the second piston 16. This invention utilizes the characteristic of the first float 15 and the second float 17 rising and falling with the waves to drive the first piston 14 and the second piston 16 to move relative to the damping generator 4. This allows the damping generator 4 to generate electricity under the action of the first piston 14 and the second piston 16. Furthermore, the up-and-down movement of the second piston 16 causes the gas in the inner air chamber 8 to be periodically compressed and expanded with the waves, which in turn drives the turbine generator 6 to generate electricity through the ventilation duct 9. Simultaneously, the ocean current below the water surface impacts the first thruster plate 12 and the second thruster plate 13, which drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 causes the rotary generator 5 inside the casing 10 to generate electricity. Thus, this invention utilizes wave energy, air compression energy (wind energy), and ocean current energy to generate electricity, offering advantages such as simple structure and high energy efficiency. This invention improves the utilization rate of wind energy, wave energy, and ocean current energy, and can absorb wave energy and ocean current energy in all directions (360°), thereby increasing the absorption rate of wave energy and ocean current energy.

[0019] Preferred, such as Figure 3 As shown, the top end of the sleeve 10 is provided with an annular groove 20, and an I-shaped rotating block 21 is provided inside the annular groove 20. A traction power generation device is provided in the middle of the rotating block 21, and a pull rope 22 is wound around the traction power generation device. The two ends of the pull rope 22 are respectively connected to the corresponding second counterweight 19. The traction power generation device is a conventional rotor and stator. The rotor is connected to the pull rope 22 and rotates by pulling the pull rope 22. In this embodiment, when the second float 17 rises and falls, the second float 17 pulls the rotor to rotate through the pull rope 22 to generate electricity, thereby further improving the energy utilization rate. In addition, since the second float rotates, the annular groove allows the I-shaped rotating block 21 to rotate with it without detachment.

[0020] Working principle

[0021] Utilizing the characteristics of the first float 15 and the second float 17 rising and falling with the waves, the first piston 14 and the second piston 16 can be driven to move relative to the damping generator 4, so that the damping generator 4 generates electricity under the action of the first piston 14 and the second piston 16. Due to the up and down movement of the second piston 16, the gas in the inner air chamber 8 is compressed and expanded periodically with the waves, which in turn drives the turbine generator 6 to generate electricity through the ventilation duct 9. At the same time, the ocean current below the water surface will collide with the first thruster plate 12 and the second thruster plate 13, which drive the rotating shaft 11 to move. The rotation of the rotating shaft 11 causes the rotary generator 5 inside the sleeve 10 to generate electricity.
