[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 are within the scope of protection of the present invention.

[0020] In the present invention, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, the phrase "comprising an element" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0021] See also Figure 1-8 , details of the embodiments of the present invention:

[0022] Intelligent automated leveraged energy storage power station, such as Figure 1 and 5As shown, it includes a lever 1, two lever pillars 2, a counterweight 10 and a doubly fed motor 11. The function of the lever 1 is to bear the gravity load at the two ends under the support of the lever pillars 2. The two lever pillars 2 are located in the middle of the lever 1 and are the support points of the entire lever mechanism. A lever bracket shaft 3 is provided on the upper part of the two lever pillars 2, and both ends of the lever bracket shaft 3 are respectively supported on the upper part of the two lever pillars 2 through bearings for bearing the mass and gravitational load of the lever mechanism. A lever moving drive gear 4 is provided in the middle part of the lever bracket shaft 3, and the lever 1 is placed on the upper part of the lever moving drive gear 4. A lever rack 5 meshing with the lever moving drive gear 4 is provided in the lower middle part of the lever 1, as shown Figure 3 and 4 As shown. The lever rack 5 and the lever 1 are fixedly connected together by a lever limit frame 9. The lever 1 passes through the lever limit frame 9 and is fixedly connected to the lever limit frame 9 in the middle by welding. A rack mounting groove 19 for welding and mounting the lever rack 5 is provided in the middle of the lower part of the lever limit frame 9. The meshing portion between the lever moving drive gear 4 and the lever rack 5 is also placed in the rack mounting groove 19, and the lever limit frame 9 appears to straddle the lever moving drive gear 4. The lever limit frame 9 serves to increase the strength of the lever 1 and to assemble the lever 1 and the lever rack 5 together. The lever limit frame 9 is limited on both sides by the inner side surfaces of the two lever pillars 2, which can prevent the lever 1 and the lever rack 5 assembled together by the lever limit frame 9 from being offset to the left and right positions, so as to avoid meshing deviation with the lever moving drive gear 4. The lever rack 5 is provided with movable limit blocks 20 under both ends to limit the moving stroke range of the lever rack 5.

[0023] The counterweight 10 is mounted on one end of the lever 1. This is a specialized counterweight component specifically designed for use at one end of the lever 1. Its function is to store and output electrical energy by being raised or lowered. The doubly-fed electric machine 11 is mounted on the ground at the other end of the lever 1. A traction winch 13 is attached to the output shaft of the doubly-fed electric machine 11. One end of the traction cable 12 on the traction winch 13 is connected to the other end of the lever 1. Under the control of an intelligent automation control system, the doubly-fed electric machine 11 rotates clockwise to store energy and counterclockwise to generate electricity.

[0024] A lever automatic movement drive system is provided on one side of the two lever supports 2. The lever automatic movement drive system drives the lever support shaft 3 to rotate. The lever support shaft 3 drives the lever 1 to move so that its center deviates from the center position of the lever support 2 through the engagement of the lever movement drive gear 4 and the lever rack 5. Specifically, the lever automatic movement drive system includes a drive motor 8, a drive speed change gear 6, and a drive speed change pinion 7. The drive motor 8 is fixed to the ground, the drive speed change pinion 7 is fixed to the output shaft of the drive motor 8, and the drive speed change gear 6 is fixed to one end of the lever support shaft 3. The drive speed change gear 6 and the drive speed change pinion 7 are meshed with each other. A drive gearbox body 14 is provided on the outside of the drive speed change gear 6 and the drive speed change pinion 7. The drive gearbox body 14 provides external protection and support for the speed change gear of the lever intelligent automatic movement system. The lever intelligent automatic movement system in the drive gearbox body 14 is provided with an automatic locking function to prevent the position of the lever 1 from shifting during the lifting and lowering operations.

[0025] like Figure 8 As shown, the intelligent automation control cabinet 15 is an integrated grid energy storage automation control system that integrates voltage and current stabilization, power supply, and grid connection. This system is state-of-the-art and a must-have component in existing power plants. It provides fully automated analysis and control for power storage during off-peak periods and grid connection during peak periods. The lever center forward and backward movement automatic control cabinet 16 is a specially designed and configured automatic control system for increasing energy storage density during energy storage and power generation. It automatically adjusts the forward and backward center position of the lever 1 within the lever support 2. During power generation, moving the center of the lever 1 on the lever support 2 backward a certain distance increases the amount of power generated. During off-peak periods, under the control of the intelligent automation control cabinet 15, the energy storage operation system 17 automatically supplies power to the doubly-fed generator 11, and the energy storage operation system 17 starts operating, storing excess power from the grid. During peak periods, under the control of the intelligent automation control cabinet 15, the power generation operation system 18 starts operating, and the generated power from the doubly-fed generator 11 is then fed into the grid.

[0026] Energy storage: Figure 6 As shown, during periods of low electricity consumption, the intelligent automation control cabinet 15 activates the energy storage operation system 17, supplying excess grid energy to the doubly-fed generator 11, causing it to rotate clockwise. The doubly-fed generator 11 then winds up the traction connecting cable 12 via the traction winch 13 mounted on the output shaft, lowering the end of the lever 1 corresponding to the doubly-fed generator 11 and raising the end of the lever 1 mounted with the counterweight 10. This lifting process is the energy storage operation process. The doubly-fed generator 11 uses grid energy as its power source and stores excess electricity during periods of low grid electricity consumption in the counterweight 10 at one end of the lever 1.

[0027] Power output: Figure 7 As shown, when the power grid needs to replenish electricity during the peak power consumption period, the intelligent automation control cabinet 15 immediately starts the power generation operation system 18. At this time, the lever automatic movement drive system is started, the lever center forward and backward movement automatic control cabinet 16 is started, the drive motor 8 rotates, and the torque drives the lever rack 5 to move to a certain position toward the counterweight 10 end of the lever 1 through the drive speed change pinion 7, the drive speed change gear 6, the lever bracket shaft 3 and the lever movement drive gear 4. After the shift is completed, the brake of the traction winch 13 is automatically released. Under the combined action of gravity mass and gravitational force, the counterweight 10 at the counterweight 10 end of the lever 1 begins to descend, and at the same time, the other end of the lever 1 is lifted, and the lifted end of the lever 1 is lifted from the lowest point to the highest point. This lifting process is the power generation process. Under the drag of the traction connecting cable 12, the traction winch 13 reverses and drives the doubly fed generator 11 to rotate counterclockwise, generating electricity and integrating it into the power grid.

[0028] During the power generation process of the intelligent automatic lever-type energy storage power station, Figure 8 As shown, by moving the automatic control cabinet 16 forward and backward at the center of the lever, the center point of the lever 1 is moved a certain distance from the center position of the lever support 2 to the end of the counterweight 10. As a result of the movement, the distance between the other end of the lever 1 and the center of the lever support 2 is shortened, while the end of the counterweight 10 of the lever 1 is lengthened. The torque at the end of the lengthened counterweight 10 increases, breaking the original conservation law of the lever and forming a new mechanical relationship. This new mechanical relationship is applied to the technical practice of intelligent automated lever-type energy storage power stations, increasing the torque at the end of the counterweight 10, and invisibly increasing the mass and gravity of the counterweight 10 at the end of the counterweight 10 of the lever 1. During the power generation process in which the counterweight end of the lever 1 descends and the other end of the lever 1 rises, the power generation of the doubly fed generator 11 is maximized, which substantially improves the energy storage density of the intelligent automated lever-type energy storage power station.

[0029] The present invention serves as a backup capacity for new energy sources such as wind power generation and solar power generation, ensuring the efficiency of grid connection of new energy power generation; the capacity can be large or small, without geographical terrain constraints, and can be used synchronously with power generation and distribution facilities; as a frequency-modulating and peak-shaving power source for peak shaving and valley filling in the power grid system, the peak shaving and valley filling response speed is fast and the practical efficiency is high; the operation process is pollution-free, and it is an environmentally friendly industry without environmental advantages; the manufacturing and installation costs are low, maintenance is convenient, and it is economical and practical; the facility application is convenient and safe, and the safety of electricity use is improved, with significant economic and social benefits.
