Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0033] Through the above arrangement, during the operation of the power generation device 6, the gravity pendulum 3 converts the gravitational potential energy into mechanical energy by swinging, and the swing of the gravity pendulum 3 can drive the mechanical arm 22 to make a circular motion, drive the transmission shaft 21 to rotate, and then drive the power generation device 6 to generate electricity. However, due to the friction, resistance and other factors in the mechanical system (such as bearing friction, gear friction, air resistance, etc.), these will cause energy loss. The magnetic repulsion force is provided by the magnetic device, and the additional magnetic energy is used to supplement these mechanical losses, ensuring that the gravity pendulum 3 can continue to swing, thereby maintaining the continuity of the power generation process.

The first end of the mechanical arm 22 is provided with a third fixing sleeve 223 sleeved on the transmission shaft 21 and connected to the transmission shaft 21 through a key.

[0042] In one embodiment, a magnetic mover assembly 4 is disposed on both radial sides of the magnetic mover assembly 4 .

[0043] Reference Figure 5 , Figure 6 As shown, the magnetic mover assembly 4 includes a first magnet base 41 installed at the bottom of the pendulum 32, the first magnet base 41 is installed with a first permanent magnet 42, and the first permanent magnet 42 includes a first magnet surface 421 in a (circular) arc shape; wherein the first magnet surface 421 is convex outwardly in a direction away from the pendulum 32; The radial side of the pendulum 32 is a stator mounting surface (i.e., the pendulum baffle 75), and the magnetic mover assembly 4 further includes a second magnet base 51 movably connected to the stator mounting surface, and the second magnet base 51 is mounted with a second permanent magnet 52, and the second permanent magnet 52 includes a (circular) arc-shaped second magnet surface 521; the second magnet surface 521 and the first magnet surface 421 have opposite magnetic properties and the same concave-convex direction; Under the interaction between the first magnet surface 421 and the second magnet surface 521 , the second magnet base 51 can move relative to the stator mounting surface.

[0044] The swing baffle 75 can prevent the gravity pendulum 3 from being thrown out of the equipment in the event of an accident, thereby preventing injuries.

[0045] Specifically, the first magnet base 41 and the second magnet base 51 are both in an arc-shaped structure.

[0046] Specifically, the curvature of the first magnet surface 421 is the same as the curvature of the second magnet surface 521, and a predetermined gap, specifically 2-3 mm, is left between the first magnet surface 421 and the second magnet surface 521. When the first magnet surface 421 and the second magnet surface 521 are in concentric positions, the magnetic repulsion force generated is zero.

[0047] In one embodiment, referring to Figure 7 As shown, it also includes a stator fixing seat 53, a stator reset holding mechanism 54 and a stopper 55 respectively mounted on the stator mounting surface; The stator fixing seat 53 is provided with a stator bearing seat 56; A first rotating shaft is installed in the middle of the second magnet, a second rotating shaft parallel to the first rotating shaft is installed at one end of the second magnet, and the other end of the second magnet is limited by the stopper 55; The first rotating shaft is rotatably connected to the stator bearing seat 56; The two stator reset and holding mechanisms 54 are symmetrically arranged on both axial sides of the second magnet base 51, and each includes a mounting seat 541 installed on the stator mounting surface, a first hinged arm 542 with one end hinged to the mounting seat 541, and a second hinged arm 543 with one end hinged to the other end of the first hinged arm 542, and the other end of the second hinged arm 543 is hinged to the second rotating shaft.

[0048] In one embodiment, referring to Figure 6 As shown, the magnetic mover assembly 4 also includes a first permanent magnet middle partition plate 43 and a first permanent magnet side baffle plate 44 installed on the first magnet base 41, the first magnet base 41 is provided with a first arc-shaped mounting surface, the first permanent magnet 42 includes a plurality of first permanent magnet units 422 embedded and mounted on the first arc-shaped mounting surface, the plurality of first permanent magnet units 422 are arranged in multiple rows along the arc direction of the first arc-shaped mounting surface and in multiple columns along the axial direction of the first arc-shaped mounting surface, the first permanent magnet middle partition plate 43 is used to separate two adjacent columns of the first permanent magnet units 422, the two first permanent magnet side baffle plates 44 are respectively abutted against the two outermost columns of the first permanent magnet units 422 to limit the first permanent magnet 42, the two side ends of the bottom of the pendulum 32 are provided with mounting notches, and the first permanent magnet side baffle plates 44 are connected to the walls of the mounting notches.

[0049] In one embodiment, referring to Figure 8 As shown, the magnetic stator assembly 5 also includes a second permanent magnet middle partition plate 57 and a second permanent magnet side baffle plate 58 installed on the second magnet base 51, the second magnet base 51 is provided with a second arc-shaped mounting surface, the second permanent magnet 52 includes a plurality of second permanent magnet units 522 embedded and mounted on the second arc-shaped mounting surface, the plurality of second permanent magnet units 522 are arranged in a plurality of rows along the arc direction of the second arc-shaped mounting surface and in a plurality of columns along the axial direction of the second arc-shaped mounting surface, the second permanent magnet middle partition plate 57 is used to separate two adjacent columns of the second permanent magnet units 522, and the two second permanent magnet side baffle plates 58 are respectively abutted against the two outermost columns of the second permanent magnet units 522 to limit the second permanent magnet 52.

[0050] It can be understood that the first permanent magnet unit 422 and the second permanent magnet unit 522 (distribution position and size on the corresponding magnet base) correspond one to one.

[0051] Specifically, in order to take advantage of the gravity potential energy, the swing angle of the gravity pendulum 3 is in the range of 45°-60°, and the swing angle is determined to be 47° through experiments. The larger the swing angle of the same weight pendulum, the greater the potential energy, that is, the greater the power generation, which improves the power generation efficiency.

[0052] Reference Fig. 9 As shown, it is a schematic diagram of the motion state of the gravity pendulum 3 at different positions. Exemplarily, the swing angle is 47° for explanation. During the entire power generation operation process, the gravity pendulum 3 rotates around the center (O1). Assuming that the clockwise rotation direction is the upper half cycle and the counterclockwise direction is the lower half cycle, points A and B are two inflection points running on the circumference. The angle of the corresponding mechanical arm 22 running on the circumference in the upper half cycle of the gravity pendulum 3 is 274°, and the angle of the corresponding mechanical arm 22 running on the circumference in the lower half cycle of the gravity pendulum 3 is 86°. This causes the work done by the gravity pendulum 3 in the upper half cycle and the lower half cycle to be different. Assuming that the gravity pendulum 3 does full work in the upper half cycle, the work done by the gravity pendulum 3 in the lower half cycle is part of the full work, and there is excess energy that is not used.

[0053] At point B, according to the velocity composition theorem in kinematics, the drag velocity is zero under normal circumstances, and the absolute velocity (Vr) of the gravity pendulum 3 is equal to its relative velocity (Va) along the direction of the slide 311. However, at this time, due to the excess energy not being used, an additional drag velocity is generated, and the direction is the same as Fig. 9 The direction of the involved velocity (Ve) indicated in the figure is opposite. Due to the limitation of the structure of the mechanical arm 22, the mechanical arm 22, the pin 222, the slider 23 and the slide slot 311 collide with each other, which may cause a collision sound and a loud noise, or even cause mechanical damage. Therefore, it is necessary to absorb, transform and release the excess energy.

[0054] Since the magnetic stator assembly 5 can rotate around the first rotation axis, when the gravity pendulum 3 runs to Fig. 9 Before the position of the dotted line on the right, the chord of the stator circumferential surface (second magnet surface 521) is parallel to the Z axis and in the vertical direction. When the first row of first permanent magnet units 422 in the front part of the magnetic mover assembly 4 enters the position of the magnetic stator assembly 5, there is a large angle between the magnetic mover assembly 4 and the magnetic stator assembly 5, that is, there is a large gap distance between the magnetic poles of the two. At this time, the repulsive force generated between the magnetic poles is small. As time goes by, the magnetic mover assembly 4 gradually approaches the magnetic stator assembly 5, and the gap between the magnetic poles of the mover and the stator also decreases, and the repulsive force gradually increases. This repulsive force and the force of the excess energy conversion that has not been exerted offset each other, thereby playing a buffering role and avoiding the collision of the mechanical parts. When the gravity pendulum 3 is in the position to Fig. 9 At the right dotted line position, the mover and the stator are completely corresponding (that is, the second magnet surface 521 and the first magnet surface 421 are in a concentric position), the magnetic repulsion force generated is zero, and the magnetic device is in a balanced state. This state is transferred to the beginning of the first half of the next cycle. Due to the existence of the potential energy of the gravity pendulum 3, the balance of the magnetic device is instantly broken, and the gravity pendulum 3 swings in the clockwise direction. The energy at this time is the superposition of the potential energy of the gravity pendulum 3 and the magnetic potential energy of the magnetic device. This magnetic potential energy is used to supplement the mechanical loss (including the bearing of the pendulum shaft 33, the bearing in the gear box 28, the gear, the flywheel 62, the bearing of the flywheel shaft 63, the rotor of the start / stop motor 10, and the rotor of the generator 61) and the energy loss caused by air resistance during the operation of the gravity pendulum 3. In this way, the gravity pendulum 3 is kept running uninterruptedly throughout the cycle, ensuring that the generator 61 continues to generate electricity. In addition, the second permanent magnet unit 522 on the front side of the magnetic device does not need to be installed in principle, but it can be determined according to the actual situation. If it is installed, the number of magnetic poles should be appropriately adjusted.

[0055] In one embodiment, the power generation device 6 includes a generator 61, a flywheel 62 and a flywheel shaft 63. The generator 61 is mounted on a generator mounting seat 763. The flywheel shaft 63 is rotatably connected to the flywheel mounting seat 764. The output end of the generator 61 is connected to the flywheel shaft 63. The flywheel 62 is mounted on the flywheel shaft 63. The generator 61 adopts a permanent magnet generator 61.

[0056] In one embodiment, it also includes a gear shaft 24, the output end of the start-stop device 1 is connected to the drive shaft 11 (through a coupling), the drive shaft 11 is equipped with a first gear 12, the transmission shaft 21 is equipped with a second gear 25 meshing with the first gear 12, the flywheel shaft 63 is equipped with a flywheel shaft gear 64, the gear shaft 24 is equipped with a first intermediate gear 26 meshing with the second gear 25 and a second intermediate gear 27 meshing with the flywheel shaft gear 64.

[0057] It should be noted that the first gear 12 and the first intermediate gear 26 are gears with smaller diameters, and the second gear 25 is a gear with larger diameter. The drive shaft 11 and the gear shaft 24 rotate at a relatively high speed, while the transmission shaft 21 rotates at a relatively low speed.

[0058] Specifically, the start / stop device 1 uses a start / stop motor 10 mounted on a motor mounting seat 762 to play a start / stop role.

[0059] Specifically, the gear box 28 is installed on the gear box mounting seat 761 , and the gear shaft 24 , the drive shaft 11 , and the transmission shaft 21 are all arranged in the gear box 28 .

[0060] It is understandable that the mechanical energy loss caused in the energy conversion process (including the energy consumption of the gravity pendulum 3 shaft 33, the energy consumption of the gear box 28 bearing, the flywheel 62, the start / stop motor 10, and the rotor energy consumption of the generator 61) and the energy loss caused by the resistance encountered by the pendulum in the air, these energy losses need additional energy to be supplemented. By adopting the flywheel 62 and the energy release of magnetic potential energy for supplementation, the gravity pendulum 3 can continue to operate uninterruptedly, thereby ensuring the continuous operation and power generation of the generator 61.

[0061] The arrangement of the flywheel 62 enables Fig. 9 Energy is released at the two inflection points A and B in the slide 311, so that the slider 23 slides smoothly through the two inflection points in the slide groove 311, so that the entire system can operate stably. The speed of the gravity pendulum 3 is stable during operation, avoiding excessive speed fluctuations during operation.

[0062] When the gravity pendulum 3 runs in a full cycle, the excess energy in the second half of the cycle is stored simultaneously by the magnetic device and the flywheel 62, and the energy is released in the first half of the cycle, which is equivalent to an energy storage device in effect.

[0063] In addition, a first encoder 211 is provided at one end of the transmission shaft 21, and a second encoder is provided at the fan blade end of the start / stop motor 10. This greatly facilitates the stable control of the system, especially monitoring the angle and speed of the mechanical arm 22 at two inflection points during operation.

[0064] Specifically, the electrical cabinet mounting channel steel 765 is installed with an electrical system 8, including a start / stop motor control cabinet 81, a rectifier and battery cabinet 82, and an inverter AC output cabinet 83.

[0065] Working principle of the present invention: Startup process: Method 1 (without mains power): The equipment is powered by a battery pack. The battery pack is installed in the rectifier and battery cabinet 82, providing direct current, which is converted into three-phase alternating current through an inverter. The voltage level is determined according to the rated voltage of the motor, and the three-phase inverter is installed in the inverter and AC output cabinet. After pressing the start button of the start / stop motor control cabinet 81, the start / stop motor 10 starts according to the preset program, driving the drive shaft 11 in the gear box 28 to rotate. The drive shaft 11 drives the transmission shaft 21 to rotate through gear transmission. As the robotic arm 22 rotates, the slider 23 moves in a straight line along the slide groove 311, pushing the gravity pendulum 3 to start rising clockwise (or counterclockwise) from the original position (lowest point). When the gravity pendulum 3 rises to the preset angle, i.e., the inflection point ( Fig. 9At this time, the start-up is completed, and the gravity pendulum 3 moves in the opposite direction under the action of gravity potential energy, and the slider 23 will continue to move upward along the slide groove 311. At this time, the gravity pendulum 3 enters the normal swing in the second half cycle.

[0066] Method 2: When there is mains power, the device directly connects the mains power to the inverter AC output cabinet 83, and the battery pack in the rectifier and battery cabinet 82 can be removed and not assembled. The startup process is the same as the method in method 1.

[0067] Power generation process: After the startup is completed, the gravity pendulum 3 enters normal swing, and the slider 23 will make a linear motion in the slide groove 311 of the gravity pendulum 3. The linear motion of the slider 23 drives the mechanical arm 22 to make a circular motion. Since the mechanical arm 22 is connected to the transmission shaft 21, it drives the second gear 25 on the transmission shaft 21 to rotate, and transmits power to the gear shaft 24 and the flywheel shaft 63. The flywheel shaft 63 drives the flywheel 62 to rotate, and the flywheel shaft 63 drives the generator 61 to rotate. The generator 61 then generates three-phase alternating current. The generated three-phase alternating current is rectified by the rectifying device of the rectifier and battery cabinet 82. The rectified direct current is converted into standard three-phase alternating current for use by the load through the three-phase inverter in the inverter and AC output cabinet.

[0068] During the operation of the gravity pendulum 3, the slider 23 drives the mechanical arm 22 to move along a circular trajectory. In the first half cycle, the movement angle of the mechanical arm 22 is different from that of the second half cycle. Due to the asymmetric energy consumption of the upper and lower half cycles, the energy consumed in the second half cycle is relatively small, resulting in excess energy. The excess energy is absorbed, converted and released by the magnetic device and the flywheel 62 to compensate for the mechanical energy loss in the system and the energy loss caused by air resistance, thereby effectively alleviating the energy attenuation problem during the operation of the gravity pendulum 3 and ensuring the continuous operation of the system and the continuous production of green electricity.

[0069] Shutdown process: Pressing the stop button in the start / stop motor 10 control cabinet generates a braking torque in the start / stop motor 10, and the entire equipment stops working.

[0070] In addition, the voltage generated by the power generation equipment is 380V, 50Hz three-phase AC, which sometimes deviates from the standard during actual operation. Therefore, the generated AC is rectified into DC through a rectifier to form a DC bus. On the one hand, it is used by the inverter to convert it into standard three-phase AC output for the load, and on the other hand, it is used to charge the battery pack.

[0071] The magnetic and gravity combined power generation equipment has the advantages of simple and compact structure, low noise, easy operation, no energy consumption, and no environmental pollution. It can be used as a distributed power source for off-grid / on-grid operation, or multiple power generation equipment can be connected in parallel as a centralized power station for off-grid / on-grid operation.

[0072] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
