[0002] A photovoltaic energy storage system is a technology that uses solar energy to generate electricity. By combining energy storage devices, it realizes the storage and optimized use of electric energy. Photovoltaic panels are responsible for converting solar energy into direct current, and an inverter converts the direct current into alternating current to meet the electricity demands of households and businesses.

Detailed implementation manners

[0026] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0027] Please refer to Figures 1 to 6 , the present invention provides the following technical solutions: A photovoltaic-storage integrated shared modular energy storage cabinet, including an energy storage cabinet body, the energy storage cabinet body includes a main cabinet body 1, an independent photovoltaic-storage module 2, a photovoltaic module 3 and a support mechanism 4. A driving mechanism is installed on the top of the main cabinet body 1, and the driving mechanism includes a motor 8 and a driving shaft 9. The independent photovoltaic-storage module 2 is installed at the bottom of the main cabinet body 1, and photovoltaic modules 3 are installed on the sides of the main cabinet body 1 and each independent photovoltaic-storage module 2. A photovoltaic panel 20 is screwed on the outside of the photovoltaic module 3, and each photovoltaic module 3 is on the same vertical line. A support mechanism 4 is installed on the top side of the independent photovoltaic-storage module 2. A bottom layer transmission plate 21 is integrally formed at the bottom of the photovoltaic module 3. The end of the bottom layer transmission plate 21 is integrally formed with a bottom layer collar 23. An insertion component 15 is inserted into the inner side of the bottom layer collar 23, and the bottom of the insertion component 15 presses on the top end of the independent photovoltaic-storage module 2. This photovoltaic-storage integrated shared modular energy storage cabinet generates electricity through the photovoltaic module 3 and directly transmits the generated electric energy into the main cabinet body 1 or the modular cabinet body 14 for energy storage.

[0028] When the present invention is installed, first place the main cabinet body 1 on the ground. After driving the photovoltaic module 3 to rotate through the driving mechanism on the top, it can generate electricity by using sunlight, and transmit the electric energy into the main cabinet body 1 through the internal cable for energy storage. When the energy storage cabinet is expanded later, directly install the independent photovoltaic-storage module 2 at the bottom of the main cabinet body 1, and dock the photovoltaic module 3 on the main cabinet body 1 with the photovoltaic module 3 on the subsequent modular cabinet body 14, then the motor 8 on the top can drive each photovoltaic module 3 to rotate synchronously to realize the angle adjustment function of all the photovoltaic panels 20. At the same time, during multiple expansion processes, only by controlling the lifting of the top main cabinet body 1, the subsequent independent photovoltaic-storage modules 2 can be installed below the main cabinet body 1 for energy storage.

[0029] In this embodiment, the independent optical storage module 2 includes a modular cabinet 14 and a support mechanism 4. A top bracket 6 is welded to the top of the main cabinet 1, a fixing frame 10 is welded to the side of the main cabinet 1, and a lifting sleeve 11 is integrally formed at the bottom of the end of the fixing frame 10. A hydraulic rod 12 is embedded in the lifting sleeve 11, and a pressing column 13 is screwed to the bottom of the hydraulic rod 12. The sides of the main cabinet 1 and the modular cabinet 14 are both provided with sliding grooves 5. The sliding groove 5 is a semicircular structure as a whole. The lifting sleeve 11 and the internal hydraulic rod 12 are symmetrically installed on both sides of the main cabinet 1, and the top of the drive shaft 9 is inserted into the output end of the motor 8. A top plate 7 is integrally formed at the end of the top bracket 6, and the outer shell of the motor 8 is fixed to the surface of the top plate 7 with screws. The drive shaft 9 passes downward from the middle of the top plate 7, and the lifting sleeve 11 is installed at both ends of the sliding groove 5. A plurality of photovoltaic modules 3 can be driven to rotate simultaneously only through the driving mechanism on the top main cabinet 1 , and the angle of each photovoltaic module 3 can be adjusted at the same time, thereby reducing the cost of subsequent expansion of independent photovoltaic storage modules 2 .

[0030] Specifically, after starting the motor 8 at the top, the motor 8 drives the topmost photovoltaic component 3 to rotate through the driving shaft 9 at the bottom, and the photovoltaic component 3 on the subsequent bottom modular cabinet 14 can rotate synchronously with the photovoltaic component 3 on the top layer due to the docking effect of the plug-in component 15 and the positioning column 22 and the positioning hole 19, thereby realizing the function of angle adjustment. Through this effect, the photovoltaic component 3 is controlled to always point to the position where the sunlight is irradiated, thereby improving the efficiency of power generation.

[0031] In this embodiment, the photovoltaic assembly 3 includes a top transmission plate 16, a bottom transmission plate 21 and a photovoltaic panel 20. The end of the top transmission plate 16 is integrally formed with a top collar 17. The top of the photovoltaic panel 20 is integrally formed with a thickened plate 18. The top of the thickened plate 18 is provided with a positioning hole 19. A positioning column 22 is welded to the bottom end of the bottom transmission plate 21. The positioning column 22 is aligned with the positioning hole 19. The rear end of the photovoltaic panel 20 is screwed with a threading tube 34. The threading tube 34 is inserted into the main cabinet 1 or the modular cabinet 14 from the sliding groove 5. By providing an angle adjustment function for each photovoltaic assembly 3 in the same column, the power generation efficiency of the photovoltaic panel 20 can be ensured to be at a high level in different time periods, thereby improving the power generation efficiency, and the transmission stability is high, with multiple guide support structures.

[0032] Specifically, the top photovoltaic module 3 is directly fixedly connected to the surface of the drive shaft 9 through the top collar 17. The bottom collar 23 of the photovoltaic module 3 and the top collars 17 and bottom sleeves of each photovoltaic module 3 below are all connected to the plug-in assembly 15 at the same time. Therefore, after the top drive shaft 9 drives the top photovoltaic module 3 to rotate, each of the photovoltaic modules 3 below will be sleeved on the upper positioning post 22 through the positioning hole 19 to provide a synchronous rotation process. Moreover, the top drive plate 16 and the bottom drive plate 21 respectively provide a traction effect from both ends and cooperate with the wire conduit 34 in the middle to realize the limiting and guiding function for each photovoltaic module 3, ensuring that the photovoltaic panel 20 can rotate stably.

[0033] In this embodiment, the plug-in assembly 15 includes a support bearing 25 and a fixed column 24. The fixed column 24 is welded to the bottoms of the main cabinet 1 and the modular cabinet 14. The support bearing 25 is sleeved on the surface of the fixed column 24. A plug-in column 27 is welded to the bottom of the inner ring of the support bearing 25. A convex ring 26 is integrally formed at the bottom of the outer ring of the support bearing 25. The bottom collar 23 is pressed against the top of the convex ring 26. The plug-in column 27 is embedded into the top collar 17 below. When expanding the subsequent independent energy storage module 2, only need to control the main cabinet 1 part at the top to be lifted upward, then the new independent energy storage module 2 can be embedded into the interior, reducing the difficulty of expansion. Moreover, there are multiple linkage structures between the main cabinet 1 and the independent energy storage module 2, and between two independent energy storage modules 2, improving the stability after connection between adjacent independent energy storage modules 2.

[0034] Specifically, since the fixed column 24 is installed at the bottom ends of the main cabinet 1 and the modular cabinet 14, after each photovoltaic module 3 is sleeved on the fixed column 24 through the bottom collar 23 and the inner support bearing 25, it can rotate around the fixed column 24 by means of the support bearing 25, and the plug-in column 27 at the bottom presses against the top of the modular cabinet 14 to limit the top collar 17 of the photovoltaic module 3 below, ensuring that each photovoltaic panel 20 can rotate stably.

[0035] In this embodiment, the support mechanism 4 includes a fixed shaft 28 and a support sleeve 31. The fixed shaft 28 is welded to the top of the modular cabinet 14. A rotating ring 29 is sleeved on the surface of the fixed shaft 28. A rotating plate 30 is integrally formed on the side of the rotating ring 29. The support sleeve 31 is integrally formed at the end of the rotating plate 30. A pressing groove 32 is formed at the top of the support sleeve 31. A support plate 33 is arranged at the bottom of the pressing groove 32. The pressing column 13 presses against the ground or the support plate 33 after the hydraulic rod 12 extends.

[0036] Specifically, the first main cabinet body 1 is directly installed on the ground. When installing the subsequent first modular cabinet body 14, the hydraulic rod 12 is controlled to extend. At this time, the supporting column at the bottom presses on the ground to support and lift the main cabinet body 1. At this time, the supporting mechanism 4 on the first modular cabinet body 14 rotates backward to avoid hitting the expanded hydraulic rods 12 on both sides until the modular cabinet body 14 is moved to the bottom of the main cabinet body 1. At this time, the hydraulic rod 12 is controlled to contract, and then the main cabinet body 1 can be placed on the top of the first modular cabinet body 14, and the positioning column 22 is inserted into the positioning groove, and the plugging column 27 is inserted into the top collar 17. When installing the subsequent second modular cabinet body 14, first, the supporting mechanism 4 on the first modular cabinet body 14 aligns the pressing groove 32 on the supporting mechanism 4 with the pressing column 13 at the bottom of the hydraulic rod 12. At this time, repeating the above process can still only lift the main cabinet body 1, with the first modular cabinet body 14 pressing on the ground, and the second modular cabinet body 14 is inserted between the main cabinet body 1 and the first modular cabinet body 14, thus completing the installation. The whole process does not require lifting all the cabinets that have been installed, reducing the installation difficulty and the stability after connection.

[0037] The foregoing shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
