The water that strikes the paddle falls, under the action of gravity, onto the blades of the second generator assembly. Because the blades are tilted at a preset angle, the water that falls on the blades pushes the blades to rotate horizontally, driving the inner ring support to rotate, which in turn drives the inner ring rotor at the top of the inner ring of the inner ring bearing to rotate, cutting the magnetic flux lines of the inner ring stator at the top of the inner ring bearing's outer ring to generate electricity. The dual-axis generator provided by the present invention utilizes the same portion of water flow to achieve two generations of electricity, improving the energy utilization of the water flow while also increasing power generation efficiency.

[0034] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] For easier understanding, see Figure 1 and Figure 2The application provides a double-shaft power generation device, which comprises a water jet pipeline 1, a first power generation assembly 2 and a second power generation assembly 3. The first power generation assembly 2 comprises an outer ring stator 2-1, an outer ring rotor 2-2, an outer ring bearing 2-3, an outer ring support 2-4 and a paddle 2-5. The inner ring bottom of the outer ring bearing 2-3 is fixedly connected with the top of the outer ring support 2-4. The outer ring rotor 2-2 is installed on the rack of the inner ring top of the outer ring bearing 2-3. The outer ring stator 2-1 is installed on the rack of the outer ring top of the outer ring bearing 2-3. A plurality of vertically installed paddles 2-5 are fixedly installed on the outer surface of the outer ring support 2-4 in the circumferential direction. The second power generation assembly 3 comprises an inner ring stator 3-1, an inner ring rotor 3-2, an inner ring bearing 3-3, an inner ring support 3-4 and a blade 3-5. The inner ring bottom of the inner ring bearing 3-3 is fixedly connected with the top of the inner ring support 3-4. The inner ring rotor 3-2 is installed on the rack of the inner ring top of the inner ring bearing 3-3. The inner ring stator 3-1 is installed on the rack of the outer ring top of the inner ring bearing 3-3. A plurality of vertically installed blades 3-5 are fixedly installed on the bottom side of the inner ring support 3-4 in the circumferential direction. The bottom of the outer ring support 2-4 is higher than the top of the blade 3-5. The blade 3-5 is inclined at a preset angle. The distance from the end of the blade 3-5 to the center of the inner ring support 3-4 is not less than the distance from the end of the paddle 2-5 to the center of the outer ring support 2-4. The inner ring bearing 3-3 is arranged on the inner ring inner side of the outer ring bearing 2-3. The water jet outlet of the water jet pipeline 1 is arranged opposite to the paddle 2-5.

[0036] It should be noted that the inner ring of the outer ring bearing 2-3 is rotatable. A frame for mounting the outer ring rotor 2-2 is located on top of the inner ring of the outer ring bearing 2-3. The outer ring support 2-4 is connected at its top to the bottom of the inner ring of the outer ring bearing 2-3, allowing it to rotate. The outer ring of the outer ring bearing 2-3 is stationary. A frame for mounting the outer ring stator 2-1 is located on top of the outer ring bearing 2-3. Thus, the outer ring rotor 2-2 and outer ring stator 2-1 form a structure that allows the outer ring rotor 2-2 to rotate and generate electricity by cutting the magnetic flux lines of the outer ring stator 2-1. The inner ring of the inner ring bearing 3-3 is rotatable. A frame for mounting the inner ring rotor 3-2 is located at the top of the inner ring bearing 3-3. The inner ring support 3-4 is connected at its top to the bottom of the inner ring bearing 3-3, allowing it to rotate. The outer ring of the inner ring bearing 3-3 is stationary. A frame for mounting the inner ring stator 3-1 is located at its top. The inner ring stator 3-1 is mounted on the frame at the top of the inner ring bearing 3-3. Thus, the inner ring rotor 3-2 and inner ring stator 3-1 form a structure that allows the inner ring rotor 3-2 to rotate and generate electricity by cutting the magnetic flux lines of the inner ring stator 3-1. The jet outlet of the water jet pipe 1 is aligned with the paddle 2-5 of the first power generation assembly 2. Water ejected from the jet outlet strikes the paddle 2-5, providing the thrust that drives the paddle 2-5 to rotate the outer ring support 2-4. This in turn drives the rotor on the inner ring of the outer ring bearing 2-3, cutting the magnetic flux lines of the outer ring stator 2-1 at the top of the outer ring of the outer ring bearing 2-3 to generate electricity. The paddle 2-5 can be configured as an arc. The water hitting the paddle 2-5 falls under the influence of gravity onto the blades 3-5 of the second power generation assembly 3. Because the blades 3-5 are tilted at a preset angle, the water falling on the blades 3-5 pushes the blades 3-5 to rotate horizontally, driving the inner ring support 3-4 to rotate. This in turn drives the inner ring rotor 3-2 at the top of the inner ring of the inner ring bearing 3-3, cutting the magnetic flux lines of the inner ring stator 3-1 at the top of the outer ring of the inner ring bearing 3-3 to generate electricity. The dual-axis power generation device provided by the present invention utilizes the same part of the water flow to achieve two power generation operations, thereby improving the energy utilization of the water flow and the power generation efficiency, and solving the technical problem that traditional hydroelectric generators only utilize the energy of the water flow once, resulting in low water energy utilization efficiency and low power generation efficiency.

[0037] In one embodiment, the preset angle is 15 degrees. The curve of the lift coefficient and drag coefficient of the blades 3-5 of the second power generation component 3 obtained by software simulation as a function of the angle of attack is shown as follows: Figure 3As shown, it can be seen that under normal conditions, when the angle of attack is 15°, the difference between the lift coefficient and the drag coefficient is the largest, that is, as Figure 4 As shown, when the angle of attack is 15 degrees, the blade 3-5 is best pushed to rotate when falling from above the blade 3-5 to the blade 3-5.

[0038] In one embodiment, as Figure 2 and Figure 5 As shown, the second power generation assembly 3 further comprises a support baffle 3-6 and a support spring 3-7. The support baffle 3-6 and the support spring 3-7 are located between the bottom of the outer ring support 2-4 and the top of the blade 3-5. One end of the support spring 3-7 is fixedly connected to the bottom side of the support baffle 3-6 facing the inner ring support 3-4, the other end of the support spring 3-7 is fixedly connected to the side of the inner ring support 3-4, the top of the support baffle 3-6 is movably connected to the bottom of the outer ring support 2-4, which can be connected by a hinge, the bottom of the support baffle 3-6 is inclined outward in the vertical direction, and the outermost side of the support baffle 3-6 to the center of the inner ring support 3-4 is less than the distance from the end of the blade 3-5 to the center of the inner ring support 3-4. The support baffle 3-6 and the support spring 3-7 have multiple, and the multiple support baffles 3-6 and the support springs 3-7 are circumferentially arranged around the inner ring support 3-4. When the amount of water ejected from the water ejection outlet is large, the gravitational potential energy generated by the water flowing up and down the paddle 2-5 will act on the support baffle 3-6, the support baffle 3-6 is pressed, the connected support spring 3-7 is compressed, the support baffle 3-6 moves towards the center of the inner ring support 3-4, and the cross-sectional area of the bottom through which the water flow can pass increases, which can increase the area of the water flow contacting the bottom blade 3-5 while ensuring pressure relief, thereby further enhancing the pushing effect on the blade 3-5 and accelerating the rotation of the bottom blade 3-5. When the amount of water ejected from the water ejection outlet decreases, the support baffle 3-6 returns to normal under the restoring action of the support spring 3-7, the cross-sectional area of the bottom through which the water flow can pass decreases, and the pressure of the water flow on the bottom increases, thereby increasing the thrust of the bottom blade 3-5. At the same time, at this time, the water flow contacts more of the outer edge of the blade 3-5 (i.e. away from the center of the inner ring support 3-4), and under the same flow, more force applied to the outer edge of the blade 3-5 can cause greater thrust on the blade 3-5 than on the inner edge, thereby ensuring the speed of the blade 3-5, further ensuring the speed of the inner ring rotor 3-2, and further ensuring the power generation efficiency.

[0039] In one embodiment, the dual-shaft power generation device provided by the present application further comprises a pressure regulating device 4 installed on the water ejection pipe 1 near the water ejection outlet, and the pressure regulating device 4 is used to adjust the water ejection speed of the water ejection outlet. The water ejection speed of the water ejection outlet can be adjusted by the pressure regulating device, thereby controlling the rotation speed of the outer ring rotor 2-2. As Figure 6As shown, the pressure regulating device 4 includes a water pipe support frame 4-1, a rotating motor 4-2, a screw 4-3, and an elastic blocking gasket 4-4. The water pipe support frame 4-1 is mounted on the water jetting pipe 1. The output shaft of the rotating motor 4-2 is fixedly connected to one end of the screw 4-3. The other end of the screw 4-3 passes through the water pipe support frame 4-1 and the wall of the water jetting pipe 1, communicating with the interior of the water jetting pipe 1. The end of the screw 4-3 that enters the water jetting pipe 1 is fixedly connected to the elastic blocking gasket 4-4. When the water flow in the water jet pipe 1 is low, the rotating motor 4-2 controls the screw 4-3 to rotate forward, and the screw 4-3 moves into the water jet pipe 1. At this time, the elastic blocking gasket 4-4 moves into the water jet pipe 1, and the cross-sectional area of ​​the water jet pipe 1 near the rotating motor 4-2 side is reduced. The pipe away from the rotating motor 4-2 side is not occupied. At this time, the water flow in the water jet pipe 1 will contact the outer edge of the paddle 2-5 more, pushing the outer edge of the paddle 2-5 to rotate. Compared with pushing the inner edge of the paddle 2-5, the lever arm increases, thereby increasing the torque on the entire outer ring rotor 2-2 and increasing the speed of the outer ring rotor 2-2. When the water flow in the water jet pipe 1 is high, the rotating motor 4-2 controls the screw 4-3 to rotate reversely, and the screw 4-3 moves toward the outside of the water jet pipe 1. The cross-sectional area of ​​the water jet pipe 1 near the rotating motor 4-2 side increases. Since the elastic blocking gasket 4-4 is flexible, when the cross-sectional area of ​​the water jetting pipe 1 near the rotating motor 4-2 is the largest, the entire elastic blocking gasket 4-4 can be completely fitted to the inner wall of the water jetting pipe 1, thereby making the entire water jetting pipe 1 fully open, and at this time, the water flow in the water jetting pipe 1 can pass more smoothly and stably. In a specific application scenario, the screw 4-3 extends from the pipe wall of the water jetting pipe 1 toward the side of the paddle 2-5 into the interior of the water jetting pipe 1, so that when the entire water jetting pipe 1 is fully open and the elastic blocking gasket 4-4 moves into the interior of the water jetting pipe 1, the water ejected from the water jetting outlet can impact the outer edge of the paddle 2-5, thereby increasing the torque on the outer ring rotor 2-2 and thereby increasing the speed of the outer ring rotor 2-2.

[0040] In one embodiment, Figure 2 As shown, there are multiple outer ring rotors 2-2, which are evenly spaced and circumferentially distributed on the top of the inner ring of the outer ring bearing 2-3. There are multiple outer ring stators 2-1, which are evenly spaced and circumferentially distributed on the top of the outer ring of the outer ring bearing 2-3, thereby improving the power generation efficiency of the first power generation component 2. There are multiple inner ring rotors 3-2, which are evenly spaced and circumferentially distributed on the top of the inner ring of the inner ring bearing 3-3. There are multiple inner ring stators 3-1, which are evenly spaced and circumferentially distributed on the top of the outer ring of the inner ring bearing 3-3, thereby improving the power generation efficiency of the second power generation component 3.

[0041] In one embodiment, Figure 7As shown, the dual-axis power generation device provided by the present invention also includes a detachable housing 5, in which the water jet outlet of the water jet pipe 1, the first power generation assembly 2, and the second power generation assembly 3 are arranged. The detachable housing 5 is provided to protect the first power generation assembly 2 and the second power generation assembly 3 of the dual-axis power generation device, preventing the internal components of the dual-axis power generation device from being damaged by external factors. The frame at the top of the outer ring of the outer ring bearing 2-3 of the first power generation assembly 2 can be connected and fixed to the frame at the top of the inner ring of the inner ring bearing 3-3 of the second power generation assembly 3 via a connecting assembly. The bottom of the outer ring support 2-4 of the first power generation assembly 2 is suspended. The bottom of the inner ring support 3-4 of the second power generation assembly 3 can be movably connected to the inner bottom of the detachable housing 5 via a movable connection.

[0042] In one embodiment, a water recovery device is further included. The water recovery device is installed below the second power generation component 3. The water recovery device is used to collect water that falls below the second power generation component 3 to collect water for power generation.
