Fossil fuel power generation faces challenges such as its non-renewable nature, increasing resource depletion, and environmental pollution. Clean energy sources such as solar, wind, and hydropower are inherently renewable. Using clean energy for power generation is a key technological path to addressing the global climate crisis, solving environmental pollution problems, and achieving sustainable economic and social development. Hydropower generation, on the other hand, is limited by geographical constraints such as river access. Summary of the Invention

[0005] By adopting the above technical solution, water can be replaced by other liquids. The centrifugal force conversion mechanism can be in various forms, as long as it collects the kinetic energy of the water sprayed from the outlet pipe and converts it into the rotational kinetic energy of the rotating container.

[0006] The first turbine and the auxiliary turbine are designed as vortex turbines or screw turbines according to actual conditions, and whichever one has better effect is selected.

[0007] The present invention is further configured as follows: the number of the water outlet pipes is one or more, and the water outlet pipes are arc-shaped along the length direction.

[0008] By adopting the above technical solution, the number of water outlet pipes can be one or more.

[0009] The present invention is further configured as follows: a flying saucer-shaped cover is fixed to the water inlet pipe, the flying saucer-shaped cover has a disc-shaped appearance, and the flying saucer-shaped cover covers the water outlet pipe.

[0010] By adopting the above technical solution, the flying saucer-shaped cover covers the water outlet pipe, which is used to reduce the air resistance encountered by the water outlet pipe during its rotation.

[0011] The present invention is further configured as follows: the rotating container is bowl-shaped, and the upper edge of the rotating container is bent inwardly and is close to the upper end surface of the flying saucer-shaped cover.

[0012] The present invention is further configured as follows: the lower end of the water inlet pipe is a water inlet, the upper end of the water inlet pipe is a closed structure, a sleeve is fixed to the upper end of the water inlet pipe, the sleeve is sleeved on the rotating shaft, a bearing is installed between the sleeve and the rotating shaft, and the drive motor is used to drive the sleeve to rotate.

[0013] The present invention is further configured as follows: the centrifugal generator includes a stator and a rotor, the stator is mounted on the casing, the rotor is rotatably connected to the casing, the centrifugal turbine is connected to a first transmission shaft, the first transmission shaft is fixed with a first bevel gear, the first bevel gear is meshed with a second bevel gear, the second bevel gear is fixed with a second transmission shaft, the second transmission shaft is fixed with a third bevel gear, the rotor is fixed with a fourth bevel gear, the third bevel gear is meshed with the fourth bevel gear, and the centrifugal generator also includes a carbon brush mounted on the casing.

[0014] By adopting the above technical solution, the water outlet pipe and the casing rotate, and the stator rotates together. The centrifugal turbine drives the first transmission shaft to rotate, and the first transmission shaft drives the second transmission shaft and the rotor to rotate. The rotor rotates relative to the stator, and the centrifugal generator generates electricity. The electrical energy generated by the centrifugal generator is transmitted through the carbon brushes.

[0015] It should be noted that various other water turbines in the prior art can also be used at the water outlet, as long as they can transfer kinetic energy to the centrifugal generator.

[0016] The present invention is further configured as follows: one end of the water outlet pipe away from the water inlet pipe is a water outlet, the water inlet is equipped with a one-way valve, and the water outlet is equipped with a pressure switch.

[0017] By adopting the above technical solution, the function of the one-way valve is to allow water in the rotating container to flow into the water inlet pipe from the water inlet, while the water in the water inlet pipe cannot flow out of the water inlet into the rotating container. The pressure switch is used to open or close the water outlet according to the pressure situation.

[0018] The present invention is further configured as follows: the upper edge of the rotating container is bent inward to form a U-shaped cylinder inside, the centrifugal force conversion mechanism includes a plurality of water retaining plates arranged on the inner wall of the U-shaped cylinder, the water retaining plates are provided with a water retaining surface, the water retaining surface is inclined relative to the horizontal plane, a concave cavity is formed between the water retaining surface and the inner wall of the rotating container, and the water flow sprayed from the outlet pipe impacts the water retaining surface.

[0019] By adopting the above technical solution, the water flow ejected from the outlet pipe impacts the water retaining plate, and the impact force drives the rotating container to rotate. At the same time, the water retaining surface of the water retaining plate is inclined.

[0023] By adopting the above technical solution, the rotating container drives the second generator input shaft to rotate through the third gear and the fourth gear, thereby driving the second generator to generate electricity.

[0024] The beneficial effects of the present invention are: The driving motor drives the casing and the water inlet pipe to rotate, and the water outlet pipe rotates with the water inlet pipe. The liquid level in the rotating container is higher than the water inlet and lower than the flying saucer-shaped cover. Water enters the water inlet pipe from the water inlet and enters the water outlet pipe under the action of centrifugal force and converges at the water outlet. As the speed of the water inlet pipe gradually increases until it reaches the rated speed, the liquid pressure of the pressure switch at the water outlet reaches the preset value, the pressure switch opens, and water is discharged from the water outlet, driving the centrifugal turbine to rotate. The centrifugal turbine drives the rotor of the centrifugal generator to rotate through the first transmission shaft and the second transmission shaft. The rotor forms a speed difference with the stator, and the centrifugal generator runs to generate electricity. During the flow of water in the water inlet pipe, it drives the rotating shaft to rotate through the first turbine. The rotating rotating shaft drives the first generator to run and generate electricity. During the upward flow of water, it drives the auxiliary turbine to promote the rotation of the water inlet pipe, which can reduce the input energy of the driving motor and keep the water inlet pipe rotating at the rated speed. The water sprayed from the outlet pipe hits the water retaining plate in the U-shaped cylinder. Under the impact force of the water and the downward pressure of its own weight, the rotating container is promoted to rotate, and the rotating container drives the second generator to operate and generate electricity.

[0025] The present invention utilizes centrifugal force, water power, etc. to drive the rotation of the rotating shaft through the first turbine, thereby driving the first generator to generate electricity, and promotes the rotation of the water inlet pipe through the auxiliary turbine, thereby reducing part of the energy input of the driving motor while maintaining the rotation of the water inlet pipe without affecting the water intake. The centrifugal turbine utilizes the centrifugal force and impact force generated by the water flow to drive the centrifugal generator to generate electricity, while collecting the impact force of the water outlet and the rotational force of the water's own weight to promote the rotation of the rotating container, thereby driving the second generator to generate electricity. The present invention is not limited by the limitations of the prior art that hydropower generation requires rivers, dams, water diversion channels, etc., and can fully utilize the potential energy generated by centrifugal force on the water flow to generate electricity.

[0026] The present invention can be installed in many application scenarios such as cars, ships, and outdoors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] Centrifugal hydraulic generators, such as Figures 1 to 2As shown, it includes a frame 1, which is rotatably connected to a rotating shaft 2 and a rotating container 3. Planar thrust bearings are installed at the bottom of the frame 1 and the rotating container 3. The rotating shaft 2 is vertically arranged and located at the center of the rotating container 3. A rotating sealing structure is installed between the rotating shaft 2 and the bottom of the rotating container 3. A water inlet pipe 4 is sleeved on the rotating shaft 2, and the bottom of the water inlet pipe 4 is a water inlet 43. A one-way valve is installed in the water inlet 43. The water in the rotating container 3 can enter the water inlet pipe 4 through the one-way valve, and the liquid in the water inlet pipe 4 cannot flow from the water inlet 43 to the rotating container 3 through the one-way valve. The upper end of the water inlet pipe 4 is a closed structure. Two water outlet pipes 5 are installed on the side wall of the water inlet pipe 4. The water inlet pipe 4 and the water outlet pipe 5 form a centrifugal water pipe assembly 18. The water outlet pipe 5 is arc-shaped along the length direction, and the curvature of the arc can be adjusted as needed to reduce the resistance to rotation. One end of the outlet pipe 5 is connected to the interior of the water inlet pipe 4, and the other end of the outlet pipe 5 forms a water outlet 52. A centrifugal turbine 51 is fixedly mounted inside the outlet 52. A pressure switch is also installed at the outlet 52. The pressure switch has a preset value. If the pressure at the outlet 52 falls below the preset value, the pressure switch will keep the outlet 52 closed. If the pressure at the outlet 52 reaches the preset value, the pressure switch will open the outlet 52.

[0032] A sleeve 42 is fixed to the upper end of the water inlet pipe 4. Sleeve 42 is sleeved onto the rotating shaft 2, with a bearing installed between the sleeve 42 and the rotating shaft 2. A drive motor 6 is mounted on the frame 1. A drive gear is fixed to the output shaft of the drive motor 6. A transmission gear is mounted on the sleeve 42, and the drive gear meshes with the transmission gear. The drive motor 6 rotates the sleeve 42 via the drive gear and the transmission gear, thereby driving the water inlet pipe 4 to rotate. A flying saucer-shaped cover 10 is fixed to the water inlet pipe 4. The flying saucer-shaped cover 10 has a disc-shaped outer shape and covers the water outlet pipe 5. The flying saucer-shaped cover 10 also has an opening that connects to the water outlet 52. As the water outlet pipe 5 rotates with the water inlet pipe 4, the flying saucer-shaped cover 10 serves to reduce air resistance experienced by the water outlet pipe 5. The rotating container 3 has a bowl-shaped outer shape, with its upper edge curved inward to abut against the upper end edge of the flying saucer-shaped cover 10. The upper edge of the rotating container 3 is bent to form a U-shaped cylinder 31 inside, and the water outlet 52 is aligned with the inside of the U-shaped cylinder 31 .

[0033] A centrifugal force conversion mechanism is installed within the rotating container 3. This mechanism converts the kinetic energy of the water ejected from the outlet pipe 5 into kinetic energy. This mechanism comprises multiple water retaining plates 32 disposed on the inner wall of a U-shaped cylinder 31. These plates 32 are spaced apart along the circumference of the rotating container 3. These retaining plates 32 have water retaining surfaces that are inclined relative to the horizontal plane, forming a concave cavity between the retaining surface and the inner wall of the rotating container 3. The water ejected from the outlet pipe 5 impacts the retaining surface.

[0034] like Figure 3 As shown, during the process of water being discharged from the water outlet 52, the water outlet pipe 5 always keeps rotating at a high speed following the water inlet pipe 4, so that the centrifugal turbine 51 can maintain a relatively high output speed during operation.

[0035] A first turbine 21 is fixedly mounted on the rotating shaft 2 and located inside the water inlet pipe 4. A first generator 7 is mounted on the frame 1. A first gear is fixed to the rotating shaft 2. A second gear is mounted on the input shaft of the first generator 7, and the first and second gears mesh. The first generator 7 converts the kinetic energy of the rotating shaft 2 into electrical energy.

[0036] An auxiliary turbine 41 is fixedly mounted on the inner wall of the water inlet pipe 4 . The auxiliary turbine 41 is higher than the first turbine 21 . A needle bearing is mounted between the inner edge of the auxiliary turbine 41 and the rotating shaft 2 .

[0037] The centrifugal hydroelectric generator includes a centrifugal generator 8, which includes a stator 81 and a rotor 82. The stator 81 is mounted on the casing 42, and the rotor 82 is rotatably connected to the casing 42. The centrifugal turbine 51 is connected to a first transmission shaft 11, and the first transmission shaft 11 is fixed with a first bevel gear 111, which is meshed with a second bevel gear 121. The second bevel gear 121 is fixed with a second transmission shaft 12, and the second transmission shaft 12 is fixed with a third bevel gear 122. The rotor 82 is fixed with a fourth bevel gear 13, and the third bevel gear 122 is meshed with the fourth bevel gear 13. The centrifugal generator 8 also includes a carbon brush 83 mounted on the casing 42. A bracket is mounted on the flying saucer-shaped cover 10, and the second transmission shaft 12 is mounted on the bracket through a bearing.

[0038] A second generator 9 is mounted on the frame 1. A third gear is fixed to the outer wall of the rotating container 3. A fourth gear is mounted on the input shaft of the second generator 9. The third gear meshes with the fourth gear. The second generator 9 converts the kinetic energy of the rotating container 3 into electrical energy.

[0039] The rotating container 3 contains water, and the water level 17 (i.e., the water level) is higher than the water inlet 43 and lower than the flying saucer-shaped cover 10. The horizontal plane 17 can be very close to the flying saucer-shaped cover 10, and the distance from the horizontal plane 17 to the water inlet 43 can be any distance.

[0040] It should be noted that the rotating shaft 2, rotating container 3, and the centrifugal generator's rotor 82 and stator 81 all rotate in the same direction to reduce frictional resistance. The overall mass of the centrifugal water pipe assembly 18 can be adjusted as needed to achieve the purpose of an inertial flywheel. The centrifugal water pipe assembly 18 is similar to an inertial flywheel.

[0041] Figure 3In the figure, 15 represents the direction of the centrifugal force. The water flowing out during the rotation can generate a reaction force on the pipe wall 16, which promotes the rotation of the centrifugal water pipe assembly 18 and reduces the input energy of the drive motor 6. The curvature of the water outlet pipe 4 can be adjusted to a suitable curvature to reduce the rotational resistance of the centrifugal water pipe assembly 18. Figure 3 In the embodiment, the rotation direction is designed to be clockwise. It should be noted that the present invention can also design the rotation direction to be counterclockwise.

[0042] Working Principle: First, the drive motor 6 rotates the centrifugal water pipe assembly 18. The overall rotation of the centrifugal water pipe assembly 18 generates centrifugal force, causing the water in the outlet pipe 5 to flow outward at high speed. At this time, the outflowing water is converted into kinetic energy by the centrifugal turbine 51 at the outlet 52, which drives the centrifugal generator 8 to generate electricity. Water sprayed out of the outlet 52 is converted into kinetic energy by the U-shaped cylinder 31U, which drives the rotating container 3. The rotating container 3 drives the water outlet 52 to flow out, and the water inlet 43 to flow in an equal amount of water. The water inlet 43 is converted into kinetic energy by the first turbine 21, which drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the first generator 7 to generate electricity. The water then passes through the auxiliary turbine 41 to assist the rotation of the centrifugal water pipe assembly 18, which can appropriately reduce the input energy of the drive motor 6 without affecting the water intake.
