Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, and more specifically to a photovoltaic energy storage device for a modular integrated energy system. Background Technology

[0002] With the acceleration of the global energy transition, photovoltaic power generation has been widely used due to its clean and renewable characteristics. However, traditional photovoltaic systems have limitations: on the one hand, photovoltaic power generation is affected by weather and day and night, resulting in unstable output; on the other hand, fixed-capacity energy storage devices are difficult to flexibly adapt to diverse power consumption scenarios, such as residential, commercial, or temporary power supply needs. In addition, traditional systems usually adopt a centralized design, which results in high expansion and maintenance costs, and poor compatibility between different components, leading to complex installation and low efficiency.

[0003] To enhance the flexibility and scalability of photovoltaic energy storage systems, modular design is gradually becoming a technological development trend. Modular photovoltaic energy storage equipment integrates power generation, energy storage, and control units into standardized modules, supporting plug-and-play and on-demand expansion. Users can flexibly add battery modules or photovoltaic power according to their electricity demand without replacing the entire system. The intelligent management module optimizes energy scheduling through algorithms to achieve peak-valley electricity price arbitrage or emergency backup power supply.

[0004] When photovoltaic energy storage devices are used, they convert solar energy into electrical energy and store it. However, the sun is in a moving state relative to the photovoltaic energy storage device, so the amount of solar energy that the photovoltaic energy storage device can absorb varies at different times. Current photovoltaic energy storage devices cannot automatically adjust, so the utilization of solar energy is limited.

[0005] When installing photovoltaic energy storage devices, it is difficult to determine the installation position of the solar panels and energy storage relative to sunlight, making installation difficult. Furthermore, the high internal temperature generated during the use of photovoltaic energy storage devices can cause damage. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a photovoltaic energy storage device for a modular integrated energy system to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic energy storage device for a modular integrated energy system, comprising an energy storage cabinet, a sealed cabinet door movably connected to the side of the energy storage cabinet, an installation mechanism movably connected to the top of the energy storage cabinet, a photovoltaic mechanism movably connected to the top of the installation mechanism, a heat dissipation mechanism fixedly connected to the side of the energy storage cabinet, and gas entering the energy storage cabinet from the heat dissipation mechanism; the photovoltaic mechanism includes a supporting installation frame, a servo motor fixedly connected to the side of the installation frame, a threaded rod fixedly connected to the side of the servo motor near the installation frame, a moving block threadedly connected to the side of the threaded rod, rotating shafts fixedly connected to both sides of the moving block, rotating plates fixedly connected to the sides of the rotating shafts away from the moving block, a support shaft fixedly connected to the sides of the two rotating shafts away from the moving block and close to each other, a fixed block movably connected to the side of the support shaft, and a photovoltaic panel fixedly connected to the top of the fixed block.

[0008] In a preferred embodiment, a fixed frame is fixedly connected inside the energy storage cabinet, and an energy storage module is fixedly connected inside the fixed frame. The energy storage module stores the electrical energy generated by the photovoltaic mechanism, and the energy storage module is detachable.

[0009] In a preferred embodiment, a connecting block is fixedly connected to the side of the photovoltaic panel, a fixed shaft is movably connected inside the connecting block, and support plates are fixedly connected to both sides of the fixed shaft.

[0010] In a preferred embodiment, the bottom end of the support plate is fixedly connected to the top end of the mounting frame, the bottom end of the movable block is in contact with the top end of the mounting frame, and when the photovoltaic panel is in a horizontal state, the bottom end of the photovoltaic panel is in contact with the top end of the mounting frame.

[0011] In a preferred embodiment, the mounting mechanism includes a supporting fixed plate, a rotating gear is movably connected to the center of the top of the fixed plate, a transmission gear meshes with the side of the rotating gear, an output gear meshes with the side of the transmission gear away from the output gear, a connecting shaft is fixedly connected inside the output gear, and an adjusting wheel is fixedly connected to the top of the connecting shaft.

[0012] In a preferred embodiment, the bottom end of the connecting shaft is movably connected to the top end of the fixing plate, and limit rings are fixedly connected to both sides of the bottom end of the mounting frame. The top end of the fixing plate is provided with a sliding groove for the limit rings to move.

[0013] In a preferred embodiment, the heat dissipation mechanism includes a supporting mounting block, a connecting frame fixedly connected inside the mounting block, a fan assembly fixedly connected inside the connecting frame, and a filter plate fixedly connected to the side of the mounting block away from the fan assembly.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. The present invention comprises a servo motor, a threaded rod, a fixed block, and a photovoltaic panel. When the angle of light changes, the servo motor starts and drives the threaded rod to rotate. When the threaded rod rotates, it drives the moving block to move. When the moving block moves, it drives the rotating shaft to move, thereby causing the rotating plate to rotate. When the rotating plate rotates, it drives the fixed block to move through the support shaft. When the fixed block moves, it drives the photovoltaic panel and the connecting block to rotate around the fixed shaft, thereby adjusting the angle of the photovoltaic panel to match the angle of light.

[0016] 2. This invention, by providing an adjusting wheel, an output gear, a rotating gear, and a connecting shaft, allows the energy storage cabinet to be fixed in the desired installation position during installation. Rotating the adjusting wheel drives the output gear via the connecting shaft, which in turn drives the transmission gear, causing the rotating gear to rotate. The rotating gear then drives the mounting frame and the photovoltaic panel above it to rotate, allowing the photovoltaic panel to be aligned with the light angle, thus facilitating installation.

[0017] 3. The present invention is equipped with a fan assembly and a filter plate. After long-term operation, when the temperature inside the energy storage cabinet is high, the fan assembly starts and blows air into the energy storage cabinet. The air blown in is filtered by the filter plate before entering the energy storage cabinet. After the clean air enters the interior of the energy storage cabinet, the temperature inside the energy storage cabinet is reduced, allowing it to be used for a long time.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The photovoltaic energy storage device of the modular integrated energy system involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figure 1 and Figure 2 This invention provides a photovoltaic energy storage device for a modular integrated energy system, including an energy storage cabinet 1. A sealed cabinet door 2 is movably connected to the side of the energy storage cabinet 1. An installation mechanism 5 is movably connected to the top of the energy storage cabinet 1. A photovoltaic mechanism 6 is movably connected to the top of the installation mechanism 5. A heat dissipation mechanism 7 is fixedly connected to the side of the energy storage cabinet 1. Gas inside the heat dissipation mechanism 7 enters the energy storage cabinet 1. A fixed frame 3 is fixedly connected inside the energy storage cabinet 1. An energy storage module 4 is fixedly connected inside the fixed frame 3. The energy storage module 4 stores the electrical energy generated by the photovoltaic mechanism 6, and the energy storage module 4 can be disassembled.

[0026] In this embodiment, the energy storage module 4 is detachable and stores the electrical energy generated by the photovoltaic mechanism 6. Therefore, when the photovoltaic mechanism 6 is working, the energy is freely stored through the energy storage module 4. The energy storage module 4 can be replaced at any time, making it more flexible in use.

[0027] Reference Figure 3The photovoltaic mechanism 6 includes a supporting mounting frame 601. A servo motor 602 is fixedly connected to the side of the mounting frame 601. A threaded rod 603 is fixedly connected to the side of the servo motor 602 near the mounting frame 601. A moving block 604 is threadedly connected to the side of the threaded rod 603. Rotating shafts 605 are fixedly connected to both sides of the moving block 604. Rotating plates 606 are fixedly connected to the sides of the rotating shafts 605 away from the moving block 604. Support shafts 607 are fixedly connected to the inner sides of the two rotating shafts 605 away from the moving block 604 and close to each other. A fixed block 608 is movably connected to the side of the 07. A photovoltaic panel 609 is fixedly connected to the top of the fixed block 608. A connecting block 610 is fixedly connected to the side of the photovoltaic panel 609. A fixed shaft 611 is movably connected inside the connecting block 610. Support plates 612 are fixedly connected to both sides of the fixed shaft 611. The bottom end of the support plate 612 is fixedly connected to the top of the mounting frame 601. The bottom end of the moving block 604 is in contact with the top of the mounting frame 601. When the photovoltaic panel 609 is in a horizontal state, the bottom end of the photovoltaic panel 609 is in contact with the top of the mounting frame 601.

[0028] In this embodiment, after the servo motor 602 starts, it drives the threaded rod 603 to rotate. When the threaded rod 603 rotates, it causes the moving block 604 to move, which in turn causes the rotating shaft 605 to move. Consequently, the rotating plate 606 on the side of the rotating shaft 605 rotates around the rotating shaft 605. When the rotating plate 606 rotates, it drives the support shaft 607 to move up and down. When the support shaft 607 moves up and down, it drives the fixed block 608 to move. When the fixed block 608 moves, it causes the photovoltaic panel 609 and the connecting block 610 to rotate around the fixed shaft 611, thereby changing the angle of the photovoltaic panel 609. The angle of the photovoltaic panel 609 is adapted to the angle of the light, improving the absorption efficiency of solar energy. The bottom end of the moving block 604 contacts the top end of the mounting frame 601, ensuring that the moving block 604 can move. When the photovoltaic panel 609 is in a horizontal state, it contacts the top end of the mounting frame 601. The mounting frame 601 can support the photovoltaic panel 609 and improve stability.

[0029] Reference Figure 4 The mounting mechanism 5 includes a fixed plate 501 for support. A rotating gear 506 is movably connected to the center of the top of the fixed plate 501. A transmission gear 505 meshes with the side of the rotating gear 506. An output gear 504 meshes with the side of the transmission gear 505 away from the output gear 504. A connecting shaft 502 is fixedly connected inside the output gear 504. An adjusting wheel 503 is fixedly connected to the top of the connecting shaft 502. The bottom end of the connecting shaft 502 is movably connected to the top of the fixed plate 501. Limiting rings 507 are fixedly connected to both sides of the bottom of the mounting frame 601. A sliding groove is provided at the top of the fixed plate 501 for the limiting rings 507 to move.

[0030] In this embodiment, when the adjusting wheel 503 rotates, it drives the connecting shaft 502 to rotate. When the connecting shaft 502 rotates, it drives the output gear 504 to rotate. When the output gear 504 rotates, it drives the rotating gear 506 to rotate through the transmission gear 505. When the rotating gear 506 rotates, it drives the photovoltaic mechanism 6 to rotate as a whole, so that the position of the photovoltaic mechanism 6 is adapted to the light angle of the installation position of the energy storage cabinet 1. Moreover, the rotation speed of the rotating gear 506 is relatively slow, so that it can be precisely adjusted. The limiting ring 507 moves in the groove of the fixed plate 501 to ensure the stability of the photovoltaic mechanism 6 when it rotates as a whole.

[0031] Reference Figure 5 The heat dissipation mechanism 7 includes a mounting block 701 for support, a connecting frame 702 is fixedly connected inside the mounting block 701, a fan assembly 703 is fixedly connected inside the connecting frame 702, and a filter plate 704 is fixedly connected to the side of the mounting block 701 away from the fan assembly 703.

[0032] In this embodiment, when the fan assembly 703 starts, it blows air into the energy storage cabinet 1. The blown air is filtered by the filter plate 704 before entering the energy storage cabinet 1. After the clean air enters the interior of the energy storage cabinet 1, the temperature inside the energy storage cabinet 1 is reduced, so that the energy storage module 4 can be used for a long time without being damaged.

[0033] The working principle of this invention is as follows: During installation, after fixing the energy storage cabinet 1 in the installation position, the adjusting wheel 503 is rotated. When the adjusting wheel 503 rotates, it drives the connecting shaft 502 to rotate. When the connecting shaft 502 rotates, it drives the output gear 504 to rotate. When the output gear 504 rotates, it drives the rotating gear 506 to rotate through the transmission gear 505. When the rotating gear 506 rotates, it drives the photovoltaic mechanism 6 to rotate as a whole, so that the position of the photovoltaic mechanism 6 is adapted to the light angle of the installation position of the energy storage cabinet 1.

[0034] After the energy storage cabinet 1 is installed, when the position of sunlight changes, the servo motor 602 starts and drives the threaded rod 603 to rotate. When the threaded rod 603 rotates, the moving block 604 moves. When the moving block 604 moves, it drives the rotating shaft 605 to move. Then, the rotating plate 606 on the side of the rotating shaft 605 rotates around the rotating shaft 605. When the rotating plate 606 rotates, it drives the support shaft 607 to move up and down. When the support shaft 607 moves up and down, it drives the fixed block 608 to move. When the fixed block 608 moves, it causes the photovoltaic panel 609 and the connecting block 610 to rotate around the fixed shaft 611, thereby changing the angle of the photovoltaic panel 609 and adapting the angle of the photovoltaic panel 609 to the angle of the light.

[0035] When the energy storage module 4 inside the energy storage cabinet 1 generates high temperature due to prolonged use, the fan assembly 703 starts. When the fan assembly 703 starts, it blows air into the energy storage cabinet 1. The air blown in is filtered by the filter plate 704 before entering the energy storage cabinet 1. After the clean air enters the interior of the energy storage cabinet 1, the temperature inside the energy storage cabinet 1 is reduced, allowing the energy storage module 4 to be used for a long time without being damaged.

[0036] In conclusion, the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
