Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, specifically to a large-scale gravitational potential energy conversion-driven power generation device and its usage method. Background Technology

[0002] Gravitational potential energy conversion power generation, as an important form of sustainable energy utilization, has attracted much attention in the energy transition process due to its advantages of being clean and pollution-free and having a stable energy source. Multi-bar linkage structures have become the mainstream design direction for large-scale gravitational potential energy conversion drive mechanisms because they can amplify the gravitational torque through the coordinated action of multiple lever arms. They convert gravitational potential energy into rotational kinetic energy, thereby driving the operation of power generation equipment. Such mechanisms need to meet the requirements of large-scale and high-load operation, which puts forward stringent requirements on structural rigidity, force balance and long-term stability. They are widely used in scenarios such as large-scale power supplementation and distributed energy supply.

[0003] Existing energy conversion technologies generally have significant limitations. Traditional fossil fuels rely on renewable resources such as coal and oil and gas, which not only face the risk of resource depletion but also cause environmental pollution. Renewable energy sources such as solar, wind, and hydropower are subject to strict limitations due to seasonal changes, weather conditions, and geographical regions. For example, solar energy depends on sunlight, wind energy depends on wind power, and hydropower depends on specific hydrological and topographical conditions, which makes energy production prone to interruption and output power fluctuate drastically, making it impossible to achieve uninterrupted power supply around the clock. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a large-scale gravity potential energy conversion-driven power generation device and its usage method, which solves the problems of existing renewable energy solutions that rely on specific geographical and hydrological conditions, resulting in energy production being constrained by external factors, unstable output, and inability to provide continuous power supply.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large-scale gravitational potential energy conversion-driven power generation device, comprising a connecting hub, a uniformly distributed pad fixedly connected at the center of the outer diameter of the connecting hub, power arms provided on both sides of the pads, the power arms being fixedly connected to the outer diameter surface of the connecting hub, a lifting mechanism installed on the top of the pads, a first X-shaped support frame fixedly connected between the outer ends of two adjacent power arms, a second X-shaped support frame fixedly connected at a position slightly below the center of two adjacent power arms, two first pulleys fixedly connected to the top of the first X-shaped support frame, the two first pulleys being symmetrically arranged, a movable gravity bar slidably connected to the inner diameter of several power arms, a steel cable fixedly connected to the top of the movable gravity bar, and a central shaft fixedly connected to the inner diameter of the connecting hub.

[0006] By adopting the above technical solution, the symmetrical arrangement and synchronous linkage of thirty-two sets of power arms are achieved through the combination structure of evenly distributed pads and double-sided power arms. The overall rigidity and force balance of the power arms are enhanced through the graded support design of the first X-shaped support frame and the second X-shaped support frame. Through the sliding cooperation between the power arms and the movable gravity bar, the position of the gravity application point can be flexibly adjusted. Through the transmission adaptation of pulleys and steel cables, the precise displacement control of the gravity bar is achieved. Therefore, the technical effects of multi-bar coordinated force generation, stable output of gravitational potential energy difference, and strong structural load-bearing capacity are obtained, providing a reliable structural foundation for continuous rotational power generation.

[0007] Preferably, the lifting mechanism includes a motor, which is fixedly connected to the pad block. A drive wheel is fixedly connected to the output end of the motor, and the drive wheel is fixedly connected to the pad block. Second pulleys are provided on both the left and right sides of the pad block.

[0008] By adopting the above technical solution, the power transmission path is simplified and the transmission efficiency is improved due to the direct drive structure of the motor and drive wheel; the motor and drive wheel are integrated and installed by the pad block to achieve a compact layout of the power unit; and the steering and guiding effect of the second pulley optimizes the force angle of the steel cable and reduces transmission loss. Therefore, the technical effects of precise displacement control of the movable gravity bar, efficient power transmission, and compact structural layout are achieved, ensuring that the gravity bar moves quickly in response to the preset trajectory.

[0009] Preferably, an electric slip ring is fixedly connected to the left side of the connecting hub, and a motor controller is fixedly connected to the right side of the connecting hub. Both the electric slip ring and the motor controller pass through the central shaft.

[0010] By adopting the above technical solution, the synchronous rotation design of the electric slip ring and the connecting hub achieves stable signal and power transmission during rotation. The integrated installation of the motor controller shortens the control signal transmission distance. The coaxiality of the electric slip ring and the controller is ensured by the through-shaft installation structure. Therefore, the technical effects of uninterrupted signal transmission, rapid control response, and good equipment operation coordination during rotation are achieved, providing a guarantee for precise timing control.

[0011] Preferably, bearings are fixedly connected to both the left and right sides of the central shaft surface, connecting parts are installed on the outer diameter of both bearings, and brackets are fixedly connected to the bottom of both connecting parts.

[0012] By adopting the above technical solution, the radial and axial loads during rotation are reduced due to the matching design of the self-aligning roller bearing and the central shaft. The rigid connection between the connector and the bracket achieves stable support for the central shaft. The symmetrical arrangement of the double-sided bracket balances the center of gravity of the overall equipment. Therefore, the technical effects of low rotational resistance of the connecting hub, high installation stability, and low wear during long-term operation are achieved, extending the service life of the equipment and reducing energy consumption.

[0013] Preferably, a first connecting bracket is fixedly connected to both the left and right sides of two adjacent first X-shaped support frames, and a second connecting bracket is fixedly connected to both the left and right sides of two adjacent second X-shaped support frames.

[0014] By adopting the above technical solution, the dispersed X-shaped support frame is formed into an overall force network through the hierarchical connection of the first connecting bracket and the second connecting bracket. The symmetrical connection structure on the left and right sides offsets the lateral force during the rotation of the power arm. The complementary support with the X-shaped support frame strengthens the rigidity of the outer end and middle section of the power arm. Therefore, the mechanism achieves the technical effect of strong overall deformation resistance, uniform force distribution, and no vibration during operation, which is suitable for the high-intensity operation requirements of large equipment.

[0015] Preferably, the steel cable passes sequentially around the first pulley, drive wheel, second pulley and inner diameter of the power arm on an adjacent side, and the bottom of the steel cable is fixedly connected to the other end of the steel cable.

[0016] By adopting the above technical solution, the direction of force on the steel cable is changed and friction loss is reduced due to the multi-pulley guided winding path. The fixed connection between the two ends of the steel cable and the movable gravity bar enables synchronous traction of the upper and lower ends of the gravity bar. The concealed wiring in the inner diameter of the power arm avoids the wear of exposed steel cables. Therefore, the technical effect of high steel cable transmission efficiency, long service life, and smooth and jam-free movement of the movable gravity bar is achieved, ensuring the reliability of power transmission.

[0017] Preferably, the steel cable on the left is in the same direction as the steel cable on the right, passes through the bottom and wraps around once before contacting the second pulley on the left.

[0018] By adopting the above technical solution, the synchronous movement of the gravity bars in the left and right power arms is ensured by arranging the double-sided steel cables in the same direction. The tension design of wrapping one loop around the bottom increases the contact area between the steel cable and the pulley, preventing slippage. The precise contact with the second pulley optimizes the force transmission angle. Therefore, the technical effect of good synchronization of double-sided transmission, stable steel cable tension, and no slippage in power transmission is achieved, thus improving the stability of gravitational potential energy conversion.

[0019] A method of using a large-scale gravitational potential energy conversion-driven power generation device, the method comprising the following steps:

[0020] First, install and fix the bracket. Then, install the electric slip ring on the left side of the connecting hub and the motor controller on the right side of the connecting hub. Then, pass the central shaft through the center of the electric slip ring on the left side, through the connecting hub, and through the center of the motor controller.

[0021] Then, the two bearings are installed on the left and right sides of the central shaft respectively. After the bearings are fixed with the connectors, they are installed on the top of the bracket. The hub surface is divided into 28-36 surfaces, and a pad is installed on each surface.

[0022] Furthermore, two power arms are installed on each surface of the connecting hub. Each power arm contains a movable gravity bar. Each pad is equipped with a motor and a corresponding drive wheel. The two ends of the steel cable are fixed to the upper and lower ends of the movable gravity bar respectively. The motor drives the drive wheel, causing the movable gravity bar to move in the power arm.

[0023] With the support as the central axis, the movable gravity bar on the left is located at the outermost side of the power arm, while the movable gravity bar on the right is located at the innermost side of the power arm. At this time, because the movable gravity bars on the left and right sides are in different positions, the drive mechanism is unbalanced. The left side swings down under the action of gravity due to the imbalance of gravity. When each set of power arms passes the support, the motor starts and drives the drive wheel to rotate, lifting the movable gravity bar to the innermost side of the power arm. When each set of power arms rises to the top, it pulls the movable gravity bar to the outermost side of the power arm.

[0024] The cycle repeats continuously, causing the drive mechanism to rotate continuously due to gravity, and the kinetic energy is transmitted through the chain and gearbox, thereby driving the generator to generate electricity.

[0025] By adopting the above technical solution, the standardized step-by-step installation process ensures the installation accuracy and coaxiality of each component. By setting the initial position difference of the left and right gravity bars, the initial gravitational potential energy difference is quickly established. The position of the gravity bars is cyclically switched by position-triggered adjustment during the rotation of the power arm. The rotation mode driven by gravity imbalance maximizes the utilization of gravitational potential energy. Therefore, the technical effects of convenient installation and operation, rapid initial start-up, continuous conversion of gravitational potential energy, and stable and continuous power generation are achieved, reducing equipment start-up energy consumption and improving power generation efficiency.

[0026] Preferably, the moving stroke of the movable gravity bar within the power arm is not less than three-quarters of the length of the power arm, and the moving speed of the movable gravity bar is positively correlated with the rotational linear velocity of the connecting hub.

[0027] By adopting the above technical solution, the displacement difference of the gravity application point is maximized due to the large stroke design, thereby improving the output of gravitational torque. The positive correlation control between the moving speed and the rotational linear speed ensures that the adjustment of the gravity bar position matches the rotational rhythm of the mechanism. Through the adaptive adjustment of the motor power, the rotational speed of the mechanism is dynamically balanced. Therefore, the technical effect of high gravitational potential energy conversion efficiency and stable operating speed of the mechanism is achieved, ensuring the stability of power generation.

[0028] Preferably, the electric slip ring provides real-time feedback of the rotation timing signal of the connecting hub to the motor controller. The motor controller precisely controls the forward or reverse rotation and output torque of the motor on the corresponding pad according to the signal, and adjusts the winding and unwinding length of the steel cable through the drive wheel.

[0029] By adopting the above technical solution, the rotational position of the power arm is accurately captured by the real-time timing feedback of the electric slip ring. The motor controller enables precise triggering control to achieve timing synchronization of motor start-stop and forward / reverse rotation. The output torque is dynamically adjusted to adapt to the force requirements of different positions. Therefore, the technical effects of precise switching of gravity bar position, good coordination of each power unit, and strong rotational continuity of the mechanism are achieved, ensuring the continuous generation of gravitational potential energy difference.

[0030] This invention provides a large-scale gravitational potential energy conversion-driven power generation device and its usage method. It has the following beneficial effects:

[0031] 1. This invention employs a zero-consumption energy conversion technology solution that utilizes gravitational potential energy drive and multi-bar linkage rotation. Gravity is used as the core driving source to drive the generator, eliminating the need for reliance on biological resources. Through the dynamic balance design of the symmetrically arranged power arms and movable gravity rods, energy cyclic conversion is achieved. Compared to existing renewable energy solutions that rely on specific geographical and hydrological conditions, solar energy solves the problems of energy production being constrained by external factors, unstable output, and inability to provide continuous power supply. Its large-scale application can not only flexibly respond to changes in power load and play a peak-shaving role, but also effectively compensate for the intermittent power supply shortcomings of the existing power system, significantly improving the operational stability and security of the power system.

[0032] 2. This invention employs a control technology scheme that combines electric slip ring timing feedback, precise motor controller control, and coordinated movement and rotation speed of the movable gravity bar. By capturing the rotational state of the connecting hub in real time through the electric slip ring, the motor controller precisely controls the forward and reverse rotation and output torque of the motor according to preset logic, thereby achieving adaptive position switching of the movable gravity bar within the power arm. This achieves the technical effect of stable and continuous generation of gravitational potential energy difference and a smooth and uninterrupted rotational power generation process. It solves the shortcomings of large timing deviation of gravity bar position switching, violent speed fluctuations, and low gravitational potential energy conversion efficiency, significantly improving the stability and effectiveness of energy conversion.

[0033] 3. This invention adopts a transmission technology solution of multi-pulley guidance, closed-loop steel cable traction, and double-sided steel cable cooperative winding. The first and second pulleys optimize the force direction of the steel cable, the closed-loop structure ensures the stability of traction, and the double-sided steel cable winding in the same direction and cross-fitting design enhances the transmission synergy. It achieves the technical effects of high-efficiency power transmission, low steel cable wear, and no transmission slippage. It solves the shortcomings of steel cable slippage, severe uneven wear, and power transmission interruption that are prone to occur during the transmission process, reduces the equipment maintenance frequency, and extends the overall service life of the transmission system.

[0034] 4. This invention adopts a standardized step-by-step installation and gravity rod position cyclic switching collaborative method. By standardizing the assembly process of components such as the bracket, central shaft, and power arm, it ensures installation accuracy. Through the cyclic logic of initial gravity imbalance start-up and trajectory-triggered position adjustment, it realizes the autonomous and continuous rotation of the equipment. It achieves the technical effects of simple installation and operation, no need for additional power to start up, and controllable operation. Compared with the existing technology of similar power generation equipment, which has a complex installation process, relies on external drive for start-up, and is difficult to control the operating status, this invention solves the shortcomings of high installation cost, high start-up energy consumption, and easy loss of control during operation. It significantly reduces the difficulty of equipment deployment and maintenance and is suitable for large-scale promotion and application. Attached Figure Description

[0048] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see the appendix Figure 1 -Appendix Figure 11 This invention provides a large-scale gravitational potential energy conversion-driven power generation device, including a connecting hub 7. A uniformly distributed pad block 11 is fixedly connected to the center of the outer diameter of the connecting hub 7. Power arms 2 are provided on both sides of the pad block 11, and the power arms 2 are fixedly connected to the outer diameter surface of the connecting hub 7. A lifting mechanism is installed on the top of the pad block 11. A first X-shaped support frame 3 is fixedly connected between the outer ends of two adjacent power arms 2. A second X-shaped support frame 6 is fixedly connected at a position slightly below the center between two adjacent power arms 2. Two first pulleys 10 are fixedly connected to the top of the first X-shaped support frame 3, and the two first pulleys 10 are symmetrically arranged. Movable gravity bars 18 are slidably connected to the inner diameter of several power arms 2. One end of a steel cable 5 is fixedly connected to the top of the movable gravity bar 18. A central shaft 15 is fixedly connected to the inner diameter of the connecting hub 7.

[0050] Specifically, the connecting hub 7 is made of high-strength steel and forged in one piece, while the pad 11 is made of cast iron and is fastened to the mounting plane of the connecting hub 7 with high-strength bolts. The number of bolts corresponds one-to-one with the mounting plane. The power arms 2 are symmetrically distributed on the left and right sides of each pad 11 in groups of two and are fixed to the connecting hub 7 by full welding. The first X-shaped support frame 3 and the second X-shaped support frame 6 are both welded. The top of the first X-shaped support frame 3 is fixed with two first pulleys 10 by bolts. The pulley axis is parallel to the central axis of the power arm 2. The movable gravity bar 18 and the inner wall of the power arm 2 are reserved with a suitable fitting gap to ensure smooth sliding. One end of the steel cable 5 is fixed to the top lug of the movable gravity bar 18 by a rope clamp. The thickness of the lug meets the traction strength requirements.

[0051] The lifting mechanism includes a motor 9, which is fixedly connected to a pad block 11. A drive wheel 13 is fixedly connected to the output end of the motor 9, and the drive wheel 13 is fixedly connected to the pad block 11. A second pulley 12 is provided on both the left and right sides of the pad block 11.

[0052] Specifically, motor 9 is a three-phase asynchronous motor, and its power and speed are adapted to the weight and movement requirements of the movable gravity bar 18. It is bolted to the pad 11 through the motor base. The output shaft of motor 9 and drive wheel 13 are connected to each other through a flat key to achieve torque transmission. The surface of drive wheel 13 is machined to fit the rope groove of steel cable 5. Both ends are rotatably connected to pad 11 through bearings. The second pulley 12 is made of wear-resistant material and is fixed to the left and right sides of pad 11 through a bracket. The height of the bracket is adjusted so that the tangent of steel cable 5 and pulley groove surface are in contact to avoid uneven wear of steel cable 5.

[0053] An electric slip ring 14 is fixedly connected to the left side of the connecting hub 7, and a motor controller 17 is fixedly connected to the right side of the connecting hub 7. Both the electric slip ring 14 and the motor controller 17 pass through the central shaft 15.

[0054] Specifically, the electric slip ring 14 adopts a through-hole structure with a hole diameter adapted to the size of the central shaft 15. It is fixed to the left end face of the connecting hub 7 by bolts. Its stationary end is connected to the external power supply and control circuit, and its rotating end is connected to the motor 9 and the motor controller 17 through wires. The motor controller 17 adopts a PLC integrated control structure and is fixed to the right end face of the connecting hub 7 by a mounting flange. The flange hole diameter maintains a clearance fit with the central shaft 15. The central shaft 15 passes through the center hole of the electric slip ring 14 and the motor controller 17. The three ensure a high degree of coaxiality to reduce rotational interference.

[0055] Bearings 16 are fixedly connected to both sides of the surface of the central shaft 15. Connecting parts 8 are installed on the outer diameter of the two bearings 16. Supports 1 are fixedly connected to the bottom of the two connecting parts 8.

[0056] Specifically, the central shaft 15 is made of high-quality structural steel and its surface is strengthened to improve wear resistance and fatigue resistance. The bearing 16 is a self-aligning roller bearing adapted to the load of the central shaft. The inner ring is interference-fitted with the central shaft 15, and the outer ring is transition-fitted with the bearing seat of the connecting piece 8. The bottom is fixed to the top of the bracket 1 by high-strength bolts. The bracket 1 is welded from structural steel and its height meets the equipment installation requirements. The bottom is fixed to the foundation by anchor bolts. During installation, the verticality of the bracket and the horizontality of the top surface are ensured.

[0057] A first connecting bracket 4 is fixedly connected to both the left and right sides of two adjacent first X-shaped support frames 3, and a second connecting bracket 19 is fixedly connected to both the left and right sides of two adjacent second X-shaped support frames 6.

[0058] Specifically, both the first connecting bracket 4 and the second connecting bracket 19 are made of round steel pipe, and their lengths are adapted to the spacing between two adjacent X-shaped support frames. The two ends of the first connecting bracket 4 are welded and fixed to the intersection nodes of the first X-shaped support frame 3, and the two ends of the second connecting bracket 19 are welded and fixed to the intersection nodes of the second X-shaped support frame 6. The weld size meets the connection strength requirements, and all connecting brackets form a closed support network to strengthen the overall structural rigidity.

[0059] The steel cable 5 passes sequentially around the first pulley 10, the drive wheel 13, the second pulley 12 and the inner diameter of the power arm 2 on the adjacent side, and the bottom of the steel cable 5 is fixedly connected to the other end of the steel cable 5.

[0060] Specifically, the steel cable 5 is made of high-strength steel wire rope. When it passes over the first pulley 10 and the second pulley 12, it maintains a suitable winding angle. When it passes over the drive wheel 13, the number of winding turns ensures sufficient friction. When the steel cable 5 passes through the inner diameter of the power arm 2, it is arranged to fit against the inner wall. The bottom is fixed to the other end of itself by a rope clamp to form a closed-loop traction structure. The tightening torque of the rope clamp meets the anti-loosening requirements.

[0061] The left steel cable 5 is in the same direction as the right steel cable 5, passes through the bottom and wraps around once before contacting the second pulley 12 on the left.

[0062] Specifically, the left steel cable 5 and the right steel cable 5 adopt the same winding direction. After winding, the left steel cable 5 contacts the tangent of the groove surface of the left second pulley 12. The contact angle ensures that the direction of force transmission is consistent with the direction of movement of the movable gravity bar 18.

[0063] Please see the appendix Figure 12 A method for using a large-scale gravitational potential energy conversion-driven power generation device, the method comprising the following steps:

[0064] First, install and fix the bracket 1. Then, install the electric slip ring 14 on the left side of the connecting hub 7 and install the motor controller 17 on the right side of the connecting hub 7. Then, pass the central shaft 15 through the center of the electric slip ring 14 on the left side, through the connecting hub 7, and through the center of the motor controller 17.

[0065] Then, the two bearings 16 are installed on the left and right sides of the central shaft 15 respectively. After the bearings 16 are fixed by the connector 8, they are installed on the top of the bracket 1 respectively. The surface of the connecting hub 7 is divided into 28-36 surfaces, and a pad 11 is installed on each surface.

[0066] Furthermore, two power arms 2 are installed on each surface of the connecting hub 7. Each power arm 2 has a movable gravity bar 18 inside. Each pad 11 is equipped with a motor 9 and a corresponding drive wheel 13. The two ends of the steel cable 5 are fixed to the upper and lower ends of the movable gravity bar 18 respectively. The motor 9 drives the drive wheel 13, so that the movable gravity bar 18 moves in the power arm 2.

[0067] With the support 1 as the central axis, the movable gravity bar 18 on the left is located at the outermost side of the power arm 2, while the movable gravity bar 18 on the right is located at the innermost side of the power arm 2. At this time, because the movable gravity bars 18 on the left and right sides are in different positions, the drive mechanism is unbalanced. The left side is unbalanced due to gravity and swings down under the action of gravity. When each set of power arms 2 passes the support 1, the motor 9 starts and drives the drive wheel 13 to rotate, lifting the movable gravity bar 18 to the innermost side of the power arm 2. When each set of power arms 2 rises to the top, the movable gravity bar 18 is pulled to the outermost side of the power arm 2.

[0068] The cycle repeats continuously, causing the drive mechanism to rotate continuously due to gravity, and the kinetic energy is transmitted through the chain and gearbox, thereby driving the generator to generate electricity.

[0069] Specifically, when installing bracket 1, ensure the horizontality and spacing accuracy of the top surfaces of the two brackets. After installing the central shaft 15, ensure the horizontality of the axis. When installing the pad 11, ensure its even distribution on the circumference using an indexing positioning tool. After installing the power arm 2, check its radial perpendicularity to the connecting hub 7. After installing the steel cable 5, adjust the preload to a state without slack. In the initial state, the left movable gravity bar 18 is located in the outer area of ​​the power arm 2, and the right movable gravity bar 18 is located in the inner area of ​​the power arm 2, forming an initial gravitational potential energy difference that meets the starting requirements.

[0070] The moving stroke of the movable gravity bar 18 within the power arm 2 is not less than three-quarters of the length of the power arm 2, and the moving speed of the movable gravity bar 18 is positively correlated with the rotational linear velocity of the connecting hub 7.

[0071] Specifically, the effective travel of the movable gravity bar 18 is designed to be more than three-quarters of the length of the power arm 2. The preset rotational angular velocity threshold of the connecting hub 7 is set according to the power generation requirements. When the movable gravity bar 18 moves to the outermost position of the power arm 2, the motor 9 stops working. When the movable gravity bar 18 moves to the innermost position of the power arm 2, the motor 9 also stops working.

[0072] The electric slip ring 14 provides real-time feedback of the rotation timing signal of the connected hub 7 to the motor controller 17. The motor controller 17 precisely controls the forward or reverse rotation and output torque of the motor 9 on the corresponding pad block 11 based on the signal, and adjusts the winding and unwinding length of the steel cable 5 through the drive wheel 13.

[0073] Specifically, the electric slip ring 14 collects the rotation angle and angular velocity signals of the connected hub 7 in real time at a set frequency and transmits them to the motor controller 17. The motor controller 17 has a built-in preset program. When it detects that a certain group of power arms 2 has rotated to a preset position directly below the bracket 1, it controls the corresponding motor 9 to rotate forward and output an appropriate torque. The drive wheel 13 tightens the steel cable 5 to pull the movable gravity bar 18 to the innermost side. When it detects that the group of power arms 2 has rotated to the top preset position, it controls the motor 9 to rotate in reverse and output an appropriate torque. The steel cable 5 is released to move the movable gravity bar 18 to the outermost side. The motor's forward and reverse rotation switching response is rapid, and the error in the length of the steel cable 5 is controlled within the allowable range.

[0074] Example 1

[0075] When the power arm 2 is made of PPH material, the movable gravity bar 18 is spindle-shaped, the surface of the connecting hub 7 is divided into 28 faces, and threaded holes are opened on the surface of the connecting hub 7. Threads are provided on one end of the power arm 2, and the power arm 2 is directly screwed onto the connecting hub 7. A gearbox is used to realize power speed change and transmission. The input end of the gearbox is connected to the central shaft 15, and the output end of the gearbox is connected to the input end of the generator. The rotational kinetic energy of the central shaft 15 is stably transmitted to the generator through the speed change adjustment of the gearbox.

[0076] Example 2

[0077] When the power arm 2 is made of steel pipe, the movable gravity bar 18 is cylindrical, the surface of the connecting hub 7 is divided into 32 faces, and threaded holes are opened on the surface of the connecting hub 7. The power arm 2 is threaded on one end of the surface, and the power arm 2 is directly screwed onto the connecting hub 7. A gearbox is configured, the input end of the gearbox is rigidly connected to the central shaft 15, and the output end of the gearbox is connected to the input end of the generator.
