DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6 The present invention provides the following technical solutions: a photovoltaic and storage integrated shared modular energy storage cabinet, comprising an energy storage cabinet body, the energy storage cabinet body comprising a main cabinet 1, an independent photovoltaic storage module 2, a photovoltaic assembly 3 and a supporting mechanism 4, a driving mechanism is installed on the top of the main cabinet 1, the driving mechanism comprises a motor 8 and a driving shaft 9, the independent photovoltaic storage module 2 is installed at the bottom of the main cabinet 1, and the main cabinet 1 and the sides of each independent photovoltaic storage module 2 are installed with photovoltaic assemblies 3, the outer side of the photovoltaic assembly 3 is screwed with a photovoltaic panel 20, each photovoltaic assembly 3 is on the same vertical line, a supporting mechanism 4 is installed on the top side of the independent photovoltaic storage module 2, the bottom of the photovoltaic assembly 3 is integrally formed with a bottom transmission plate 21, the end of the bottom transmission plate 21 is integrally formed with a bottom collar 23, the inner side of the bottom collar 23 is interspersed with a plug-in assembly 15, and the bottom of the plug-in assembly 15 is pressed on the top of the independent photovoltaic storage module 2. The photovoltaic-storage integrated shared modular energy storage cabinet generates electricity through the photovoltaic components 3, and directly transmits the generated electric energy to the inside of the main cabinet 1 or the modular cabinet 14 to store the electric energy.

[0028] When installing the present invention, the main cabinet 1 is first placed on the ground. After the photovoltaic assembly 3 is driven to rotate by the driving mechanism on the top, the sunlight can be used to generate electricity, and the electric energy is transmitted to the inside of the main cabinet 1 through the internal cables for electric energy storage. When the energy storage cabinet is subsequently expanded, the independent photo-storage module 2 is directly installed at the bottom of the main cabinet 1, and the photovoltaic assembly 3 on the main cabinet 1 is connected with the photovoltaic assembly 3 on the subsequent modular cabinet 14. Each photovoltaic assembly 3 can be synchronously driven to rotate by the motor 8 on the top to realize the angle adjustment function of all photovoltaic panels 20. At the same time, during multiple expansions, only the top-level main cabinet 1 can be controlled to be lifted, and the subsequent independent photo-storage module 2 can be installed under the main cabinet 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 topmost photovoltaic component 3 is directly fixedly connected to the surface of the driving shaft 9 through the top-level ring 17, and the bottom-level ring 23 of the photovoltaic component 3 and the top-level ring 17 and the bottom-level sleeve of each photovoltaic component 3 below are simultaneously connected to the plug-in component 15. Therefore, after the topmost photovoltaic component 3 is driven to rotate by the top driving shaft 9, each photovoltaic component 3 below will be mounted on the upper positioning column 22 through the positioning hole 19 to provide a synchronous rotation process, and the top-level transmission plate 16 and the bottom-level transmission plate 21 respectively achieve the limiting and guiding function of each photovoltaic component 3 through the traction effect from both ends, in conjunction with the middle threading tube 34, to ensure 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 bottom of the main cabinet 1 and the modular cabinet 14. The support bearing 25 is sleeved on the surface of the fixed column 24. The inner ring bottom of the support bearing 25 is welded with a plug-in column 27. The outer ring bottom of the support bearing 25 is integrally formed with a convex ring 26. The bottom sleeve ring 23 is pressed on the top of the convex ring 26, and the plug-in column 27 is embedded in the top sleeve ring 17 below. When the subsequent independent optical storage modules 2 are expanded, it is only necessary to control the top main cabinet 1 part to lift up, and the new independent optical storage module 2 can be embedded inside, which reduces the difficulty of expansion. There are multiple linkage structures between the main cabinet 1 and the independent optical storage module 2, and between two independent optical storage modules 2, which improves the stability of the adjacent independent optical storage modules 2 after connection.

[0034] Specifically, since the fixing column 24 is installed at the bottom end of the main cabinet 1 and the modular cabinet 14, each photovoltaic component 3 can be rotated around the fixing column 24 with the help of the support bearing 25 after being mounted on the fixing column 24 through the bottom ring 23 and the inner support bearing 25, and is pressed on the top of the modular cabinet 14 through the bottom plug-in column 27 to limit the top ring 17 of the photovoltaic component 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 provided on the top of the support sleeve 31. A supporting plate 33 is provided at the bottom of the pressing groove 32. The pressing column 13 is extended by the hydraulic rod 12 and then pressed on the ground or the supporting plate 33.

[0036] Specifically, the first main cabinet 1 is directly installed on the ground. When the subsequent first modular cabinet 14 is installed, the hydraulic rod 12 is controlled to extend. At this time, the support column at the bottom is pressed on the ground to support and lift the main cabinet 1. At this time, the support mechanism 4 on the first modular cabinet 14 rotates toward the rear to avoid colliding with the hydraulic rods 12 after the two sides are unfolded, until the modular cabinet 14 is moved to the bottom of the main cabinet 1. At this time, the hydraulic rod 12 is controlled to retract, and the main cabinet 1 can be placed on the top of the first modular cabinet 14, and the positioning column 22 is embedded in the positioning groove, and the plug-in column 27 is inserted into the positioning groove. Embedded into the top-level collar 17, and when installing the subsequent second modular cabinet 14, first the support mechanism 4 on the first modular cabinet 14 is aligned with the pressing groove 32 on the support mechanism 4 and the pressing column 13 at the bottom of the hydraulic rod 12. At this time, repeat the above process, and you can still only lift the main cabinet 1, press the first modular cabinet 14 on the ground, and embed the second modular cabinet 14 between the main cabinet 1 and the first modular cabinet 14, so as to complete the installation. The whole process does not require lifting all the cabinets that have been installed, reducing the difficulty of installation and the stability after connection.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
