Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, specifically to an intelligent coupling device for the coordinated operation of a photovoltaic inverter and an energy storage battery pack. Background Technology

[0002] In the global energy clean transition, photovoltaic power generation is being used more and more widely. However, due to the influence of sunlight, its output power is highly intermittent and fluctuates. It generates a lot of electricity during the day, but almost stops generating electricity at night or on cloudy or rainy days. This makes it difficult to meet the continuous power demand of the load and will also impact the stability of the power grid, restricting grid connection and absorption.

[0003] To address this issue, energy storage systems are gradually being integrated with photovoltaics. However, existing photovoltaic-energy storage systems are mostly distributed architectures consisting of "photovoltaic inverters + independent energy storage devices," lacking deep synergy: photovoltaic inverters only convert DC to AC in one direction, and cannot dynamically allocate power according to the state of charge of the energy storage battery pack and the grid load, which easily leads to energy waste or battery damage; the charging and discharging control of energy storage relies on independent controllers, and the data interaction with the inverter is lagging, making it difficult to achieve real-time matching of "generation-storage-use," resulting in low energy utilization.

[0004] Meanwhile, the cleanliness of photovoltaic panels directly affects photoelectric conversion efficiency, and existing cleaning methods have obvious shortcomings: manual cleaning is costly and difficult to operate in high-risk scenarios; traditional mechanical cleaning devices have limited cleaning range and poor stability, and are not linked with the photovoltaic and energy storage system, so they cannot clean automatically as needed, and dust accumulation leads to a significant decrease in power generation efficiency.

[0005] Furthermore, the independent operation of each component, the lack of a unified communication and control platform, incompatible data interfaces, and difficulties in information sharing, coupled with the absence of cleaning devices in system control, further reduce overall energy efficiency. Therefore, this invention proposes an intelligent coupling device for the coordinated operation of a photovoltaic inverter and an energy storage battery pack to address these issues. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent coupling device for the coordinated operation of a photovoltaic inverter and an energy storage battery pack, so as to solve the problems mentioned in the background art.

A bidirectional converter is connected to one side of the support frame. The bidirectional converter is used to connect the battery system and the power grid to realize bidirectional conversion of electrical energy. The bidirectional converter is connected to several energy storage battery packs on one side. These energy storage battery packs are used to store electrical energy and can provide power to the load or grid when the photovoltaic system is not generating electricity. Several of the aforementioned energy storage battery packs are connected to a communication module and a control unit on their tops. The communication module is used to realize data exchange and command transmission between the various components. The control unit is responsible for coordinating the operation of the photovoltaic inverter and the energy storage battery pack. When the control unit receives control commands from the background and combines them with the real-time power demand of the system, it controls the bidirectional converter to charge or discharge the energy storage battery pack according to the sign and magnitude of the power command, ensuring efficient system operation and electrical safety. Cleaning devices are connected to both sides of the photovoltaic solar panel. The cleaning devices are used to clean the dust accumulated on the surface of the photovoltaic solar panel to ensure the photoelectric conversion efficiency of the photovoltaic solar panel. The cleaning device includes a support device, a drive device, and a dust removal device.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0023] Example: Please refer to Figures 1-2 A smart coupling device for the coordinated operation of a photovoltaic inverter and an energy storage battery pack includes several support frames 1, with photovoltaic solar panels 2 connected to the top of the support frames 1, and a photovoltaic inverter 3 connected to one side of the bottom of the photovoltaic solar panels 2. The photovoltaic inverter 3 is used to convert the direct current generated by the photovoltaic solar panels 2 into alternating current. A bidirectional converter 4 is connected to one side of the support frame 1. The bidirectional converter 4 is used to connect the battery system and the power grid to realize bidirectional conversion of electrical energy. The bidirectional converter 4 is connected to several energy storage battery packs 5 on one side. The energy storage battery packs 5 are used to store electrical energy and can provide power to the load or grid when the photovoltaic system is not generating electricity. Several of the energy storage battery packs 5 are connected to a communication module 6 and a control unit 7 on their tops. The communication module 6 is used to realize data exchange and command transmission between the various components. The control unit 7 is responsible for coordinating the operation of the photovoltaic inverter 3 and the energy storage battery pack 5. When the control unit 7 receives control commands from the background and combines them with the real-time power demand of the system, it controls the bidirectional converter 4 to charge or discharge the energy storage battery pack 5 according to the sign and magnitude of the power command, so as to ensure efficient system operation and power safety. Cleaning devices 8 are connected to both sides of the photovoltaic solar panel 2. The cleaning devices 8 are used to clean the dust accumulated on the surface of the photovoltaic solar panel 2 to ensure the photoelectric conversion efficiency of the photovoltaic solar panel 2. The cleaning device 8 includes a support device 81, a drive device 82, and a dust removal device 83. The support device 81 is connected along both sides of the photovoltaic solar panel 2 to provide stable support for the drive device 82 connected at the top, ensuring the stability and flexibility of the drive device 82 during movement. The dust removal device 83 is connected to the top of the drive device 82. When the drive device 82 is working, it can drive the dust removal device 83 to move synchronously along the surface of the photovoltaic solar panel 2, thereby cleaning the top surface of the photovoltaic solar panel 2.

[0024] Example 2: Based on Example 1, as follows Figures 3-8 As shown, the support device 81 includes two fixed frames 811. The bottom grooves on the inner side of the two fixed frames 811 are connected to both sides of the photovoltaic solar panel 2. Each of the two fixed frames 811 has a long rod 812 on its inner top, and the top of the inner top of the two fixed frames 811 is fixedly connected to both ends of the long rod 812. The top of the two long rods 812 is provided with a first sliding rod 813, and the top of the two long rods 812 is fixedly connected to the bottom of the first sliding rod 813.

[0025] Both of the two long rods 812 are provided with first racks 814 on their inner and outer sides, and both of the two long rods 812 are fixedly connected to the rear end of the first racks 814. Each of the two first racks 814 has a first gear 815 on its outer surface, and the outer surfaces of the two first racks 814 mesh with the outer surfaces of the first gears 815. Each of the two first gears 815 has a rotating shaft 816 at its center top, and the center top of each of the two first gears 815 is fixedly connected to the bottom of the rotating shaft 816. A driving device 82 is provided at the top of each of the two rotating shafts 816, which drives the device through the inner side of the fixed frame 811. Two long rods 812 are installed at the top, and are fixed to the sides of the photovoltaic solar panel 2 by the bottom of the fixing bracket 811, providing a solid support for the long rods 812. The drive device 82 is connected to the first gear 815 through the rotating shaft 816. The rotating shaft 816 drives the first gear 815 to rotate along the outer surface of the first rack 814, thereby enabling the drive device 82 to move back and forth along the long rods 812. This not only provides a guide trajectory for the drive device 82 during movement, but also ensures the stability of the drive device 82's movement, preventing deviation from affecting the cleaning accuracy of the dust removal device 83 on the photovoltaic solar panel 2. The tops of the two rotating shafts 816 are correspondingly connected to the bottoms of the drive device 82.

[0026] The driving device 82 includes two first bevel gears 821, with their bottom centers correspondingly connected to the tops of two rotating shafts 816. Second bevel gears 822 are disposed on the outer surfaces of the two first bevel gears 821, and their outer surfaces mesh with each other. A rotating column 823 is disposed at the center of each of the two second bevel gears 822. The rotating column 823 is fixedly connected to the output shaft of a motor 824. When the motor 824 is powered on, it drives the rotating column 823 to rotate rapidly. Since the second bevel gears 822 are fixedly connected to the outer surface of the rotating column 823, their rotation drives the second bevel gears 822 to rotate synchronously, thus driving the rotation of the first bevel gears 821 through meshing transmission. The centers of the two second bevel gears 822 are fixedly connected to both ends of the rotating column 823.

[0027] The top of the rotating column 823 is equipped with a motor 824. By fixing the bottom of the first bevel gear 821 to the top of the rotating shaft 816, when the first bevel gear 821 rotates, it will drive the rotating shaft 816 to rotate synchronously, thereby causing the first gear 815 at the bottom of the rotating shaft 816 to mesh and move along the outer surface of the first rack 814. The top of the rotating column 823 is movably connected to the output shaft of the motor 824. A connecting plate 825 is provided at the bottom of the motor 824, and the bottom of the motor 824 is fixedly connected to one end of the top of the connecting plate 825. A dust removal device 83 is provided at the other end of the connecting plate 825, and the other end of the connecting plate 825 is fixedly connected to the bottom of the dust removal device 83. Sliding blocks 826 are provided at both ends of the bottom of the connecting plate 825, and both ends of the bottom of the connecting plate 825 are fixedly connected to the top of the sliding blocks 826. The sliding blocks 826, fixedly connected to the bottom of the connecting plate 825, slide synchronously on the outer surface of the first sliding rod 813. This structure not only improves the stability of movement but also prevents the drive device 82 from jamming or shifting during movement, ensuring that the dust removal device 83 efficiently cleans the surface of the photovoltaic solar panel 2. Furthermore, the grooves at the bottom of the two sliding blocks 826 are movably connected to the outer surface of the first sliding rod 813.

[0028] The dust removal device 83 includes a second rack 831, on the outer surface of which a second gear 832 is disposed, and the outer surfaces of the second rack 831 and the second gear 832 mesh with each other. A driving block 833 is disposed at the center of the second gear 832, and the center of the second gear 832 is connected to the bottom output shaft end of the driving block 833. A movable plate 834 is disposed at the bottom of the driving block 833. By distributing the second gear 832 at the bottom output shaft end of the driving block 833, when the driving block 833 is driven, it can drive the second gear 832 to mesh and rotate on the outer surface of the second rack 831. The rotated second gear 832 will then drive the movable plate 834, which is connected through the top, to move back and forth synchronously. The bottom of the driving block 833 is fixedly connected to the top of the movable plate 834.

[0029] The movable plate 834 has two pulleys 835 on each of its two protruding bottom ends, and the two protruding bottom ends of the movable plate 834 are movably connected to the outer surfaces of the two pulleys 835. Two of the pulleys 835 have second sliding rods 836 on their outer surfaces, and four of the pulleys 835 are movably connected to the outer grooves of the second sliding rods 836. The outer surfaces of the other two pulleys 835 are movably connected to the outer grooves of the second rack 831. The bottoms of the second sliding rods 836 and the second rack 831 are fixedly connected to the other end of the top of the connecting plate 825. A brush 837 is provided on the central protruding part of the top of the movable plate 834. The two pulleys 835, movably connected to the two protruding bottom ends of the movable plate 834, slide in the outer grooves of the second sliding rods 836 and the second rack 831, respectively. This structure improves the flexibility of sliding. Therefore, the movable plate 834 can not only drive the brush 837 to move back and forth, but also, under the action of the left and right movement of the driving device 82, achieve comprehensive removal of dust adhering to the top of the photovoltaic solar panel 2. Furthermore, the raised part at the top center of the movable plate 834 is fixedly connected to the top of the brush 837.

[0030] The working principle of this invention is as follows: When in operation, the photovoltaic solar panel 2 absorbs light to generate direct current, which is then converted into alternating current by the photovoltaic inverter 3 to supply the load or to the power grid; When the photovoltaic power generation exceeds the load demand, the control unit 7 receives system data through the communication module 6 and controls the bidirectional converter 4 to store the excess electrical energy into the energy storage battery pack 5. When the photovoltaic does not generate electricity or the power generation is insufficient, the control unit 7 controls the bidirectional converter 4 to release the electrical energy stored in the energy storage battery pack 5 according to the power command, to supply power to the load or to connect to the grid, ensuring the stable operation of the system. To ensure the photoelectric conversion efficiency of the photovoltaic solar panel 2, the cleaning devices 8 connected to its two sides will be activated as needed. The two fixed brackets 811 in the support device 81 are engaged and fixed to the two sides of the photovoltaic solar panel 2 through the inner bottom groove, which can provide a firm support for the long rod 812 at the top. The first sliding rod 813 fixedly connected to the top of the long rod 812, together with the first rack 814 fixedly connected to the inner and outer sides of the long rod 812, constitute the moving track of the drive device 82, ensuring stable guidance for subsequent actions. When the drive device 82 is working, after the motor 824 is powered on and started, it will drive the rotation of the rotating column 823 that is movably connected to its output shaft, thereby causing the second bevel gear 822, which is fixedly connected to both ends of the rotating column 823, to rotate synchronously with the column, and drive the first bevel gear 821, which is meshed with the outer surface, to achieve power steering, so that the rotating shaft 816, which is fixedly connected to the bottom center of the first bevel gear 821, can rotate in a certain direction. The first gear 815, which is fixedly connected to the bottom of the rotating shaft 816, will mesh and roll along the outer surface of the first rack 814 on the long rod 812. At the same time, the sliding blocks 826, which are fixedly connected to both ends of the bottom of the connecting plate 825, will also slide synchronously along the first sliding rod 813. The dual guide structure avoids jamming or deviation when the drive device 82 moves, and achieves smooth left and right movement of the whole. When the dust removal device 83 moves, the drive block 833 drives the second gear 832 connected to its bottom output shaft to mesh and rotate back and forth on the outer surface of the second rack 831, and the second gear 832 synchronously drives the movable plate 834 connected through the center to move back and forth. At the same time, the pulleys 835 connected to the protruding parts at both ends of the bottom of the movable plate 834 will roll in the outer grooves of the second sliding rod 836 and the second rack 831 respectively, thereby improving the flexibility of movement. Finally, the brush 837, which is fixedly connected to the top of the movable plate 834, sweeps across the top surface of the photovoltaic solar panel 2 in a combined action of "moving left and right + moving back and forth", effectively removing the dust accumulated on the surface and ensuring the photoelectric conversion efficiency of the photovoltaic solar panel 2.
