Containerized energy storage modules can store surplus electricity and release it when needed, achieving the goals of emergency power supply, resource allocation, rational use, and energy conservation.
[0003] With the development of new energy policies and market demand, photovoltaic energy storage has developed rapidly in the past two years, and the demand for energy storage installations has also been increasing. Existing containerized energy storage systems and photovoltaic supports are mostly independent systems, and components are also packaged separately for transportation, leading to a higher probability of lost or missing parts during transit. At the same time, existing containerized energy storage modules lack a reasonable internal layout, have a limited number of photovoltaic panels, and cannot adjust their angles in real time according to changes in the sun's position, resulting in low power generation efficiency.

[0058] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0060] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."
[0061] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0062] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0063] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this application are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, these directional indications also change accordingly.
[0064] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0065] Existing containerized energy storage systems and photovoltaic power generation devices are mostly two independent systems, and the components are also packaged and transported separately, making it easy for parts to be lost or missing during transportation. In addition, existing containerized energy storage modules also suffer from a lack of reasonable internal layout, resulting in a smaller number of photovoltaic modules and an inability to adjust their angle in real time according to changes in the sun's position, leading to low power generation efficiency.
[0066] In response, this application discloses an integrated photovoltaic and energy storage device that enables modular installation and transportation of the energy storage system and photovoltaic support. It allows for centralized packaging of photovoltaic modules and their accessories, reducing issues such as lost or missing parts during transportation and significantly improving system transportation efficiency and reliability. Furthermore, the photovoltaic modules can be installed outside and fixed to the container 100, with no limit on the number and the angle can be adjusted according to changes in the sun's position, resulting in high power generation efficiency.
[0067] In one specific embodiment, see Figures 1 to 6A photovoltaic-storage integrated device is disclosed, including a container 100, a photovoltaic power generation device 200, and an energy storage module 300. The container 100 has a receiving chamber 110. The photovoltaic power generation device 200 includes a first photovoltaic tracking bracket 400 and a first photovoltaic module 500. The first photovoltaic tracking bracket 400 includes a first drive mechanism 410 and a first main shaft 420. The first drive mechanism 410 and the first main shaft 420 are pre-installed in the receiving chamber 110 of the container 100. The container 100 has length, width, and height directions. The first main shaft 420 is perpendicular to the length or width direction of the container 100 and is connected to the first drive mechanism 410 for transmission. The energy storage module 300 is installed in the receiving chamber 110 and includes an energy storage cabinet 310. The first main shaft 420 is located on one side of the energy storage cabinet 310 along the length or width direction of the container 100.
[0068] The integrated photovoltaic and energy storage device has a first state and a second state. In the first state, the energy storage cabinet 310 is located close to the side panel 140 of the container 100 in the width direction. The first photovoltaic module 500 is installed on the first photovoltaic tracking bracket 400 and arranged in a row along the length or width direction perpendicular to the container 100. In the second state, the energy storage cabinet 310 is located in the middle of the receiving chamber 110. That is, the position of the energy storage cabinet 310 is offset from the side panel 140 by a certain distance compared to the position in the first state. It is located in the middle position along the width direction inside the container 100. The disassembled components of the first photovoltaic tracking bracket 400 and the first photovoltaic module 500 are arranged around the energy storage cabinet 310 inside the container 100.
[0069] In this embodiment, the integrated photovoltaic and energy storage device has a first state and a second state, which can be adapted to overall modular installation and transportation respectively. In the first state, the first photovoltaic module 500 is installed on the outside of the container 100 and fixed to the container 100, so that the container 100 and the photovoltaic power generation device 200 can form an overall modular structure during operation. At this time, the number of first photovoltaic modules 500 is unlimited, and the angle can be changed according to the change of the sun's position, effectively improving energy utilization efficiency. In the second state, the disassembled components of the first photovoltaic tracking bracket 400 and the first photovoltaic module 500 are arranged around the energy storage cabinet 310 inside the container 100, which can realize modular transportation, reduce the problem of lost or missing parts during transportation, and greatly improve the system's transportation efficiency and reliability.
[0070] Please continue to refer to this. Figure 1 and Figure 6As shown, the photovoltaic power generation device 200 also includes a second photovoltaic tracking bracket 600 and a second photovoltaic module 700. The second photovoltaic tracking bracket 600 includes a second drive mechanism 610 and a second main shaft 620. The second drive mechanism 610 and the second main shaft 620 are pre-installed in the receiving chamber 110 of the container 100. In the first state, the second photovoltaic module 700 is installed on the second photovoltaic tracking bracket 600 and arranged in rows along the length or width direction perpendicular to the container 100. In the second state, the disassembled components of the second photovoltaic tracking bracket 600 and the second photovoltaic module 700 are arranged around the energy storage cabinet 310 inside the container 100.
[0071] In actual production, there are multiple first main shafts 420 and multiple second main shafts 620. In the first state, the integrated photovoltaic and energy storage equipment has multiple first main shafts 420 connected end to end, extending from the inside of the container 100 to the outside of the container 100; correspondingly, multiple second main shafts 620 are also connected end to end, extending from the inside of the container 100 to the outside of the container 100. The container 100 has a clearance opening 141 on at least one side along the width or length direction, through which the first main shafts 420 and the second main shafts 620 pass. The first main shafts 420 and the second main shafts 620 are symmetrical with respect to the width direction or the centerline of the width direction of the container 100.
[0072] The clearance opening 141 can be a window on the side wall. When the clearance opening 141 is a window, there are at least two clearance openings, which correspond to the first main shaft 420 and the second main shaft 620 respectively. In another embodiment, the clearance opening 141 can also be achieved by eliminating the side wall on the container 100 body that corresponds to the first main shaft 420 or the second main shaft 620, and setting the container 100 body as an open structure. In yet another embodiment, the clearance opening 141 can also be achieved by setting the side wall on the container 100 that corresponds to the first main shaft 420 or the second main shaft 620 to have two states: open and closed. When the integrated optical storage device is in the first state, it is open, and when it is in the second state, it is closed. There are no restrictions here, as long as the first main shaft 420 and the second main shaft 620 can pass through in the first state, all of which are within the protection scope of this application.
[0073] Specifically, see Figure 2 and Figure 5The energy storage module 300 also includes an energy storage battery located within the energy storage cabinet 310. The battery is electrically connected to the first photovoltaic module 500 and the second photovoltaic module 700, and is used to store the electrical energy generated by the first photovoltaic module 500 and the second photovoltaic module 700. The energy storage cabinet 310 has two placement states to accommodate the overall modular installation and transportation of the system. When the integrated photovoltaic and energy storage device is in the first state, the energy storage cabinet 310 is positioned close to one side panel 140 of the container 100 in the width direction and at the center in the length direction. When the integrated photovoltaic and energy storage device is in the second state, the energy storage cabinet 310 is arranged in the center of the receiving chamber 110 along the width direction of the container 100, and offset from the circumference of the container 100 by a certain distance. Due to the large volume and weight of the energy storage cabinet 310, placing it in the center of the receiving chamber 110 in the length direction in the first state helps to ensure the stress balance of the container 100. When packaging and transporting, the energy storage cabinet 310 is offset from its original position and located in the middle of the width direction of the container 100. This provides sufficient space for packaging the photovoltaic power generation device 200 and its accessories, which is more conducive to the rational planning of the internal space of the container 100, realizing modular packaging and transport, applicable to various handling scenarios, reducing problems such as lost or missing parts during transportation, and greatly improving the system's transportation efficiency and reliability.
[0074] Specifically, see Figure 4 and Figure 6 The photovoltaic power generation device 200 also includes a synchronous shaft 800, which is located inside and above the receiving chamber 110 and is connected to the first drive mechanism 410 and the second drive mechanism 610.
[0075] To enable the installation of the first drive mechanism 410 and the second drive mechanism 610 in the receiving chamber 110, the photovoltaic power generation device 200 further includes a slewing support assembly. The slewing support assembly is located on the top of the receiving chamber 110 and includes a first slewing support assembly 170 and a second slewing support assembly 190. The first slewing support assembly 170 and the second slewing support assembly 190 are respectively spaced apart along the length or width direction of the container 100. The first drive mechanism 410 is located on the top of the receiving chamber 110 via the first slewing support assembly 170; the second drive mechanism 610 is located on the top of the receiving chamber 110 via the second slewing support assembly 190.
[0076] like Figure 1 , Figure 2 The diagram shown is a schematic of the integrated photovoltaic and energy storage device in its first state. In this embodiment, see [link to diagram]. Figure 2 , Figure 4 and Figure 6The first drive mechanism 410, the first main shaft 420, and the energy storage cabinet 310 are located within the receiving chamber 110 of the container 100. The container 100 includes a top plate 120, a bottom plate 130, two side plates 140, a rear panel 150, and an opening 160, forming a rectangular box. The top plate 120 and the bottom plate 130 are positioned opposite each other along the height direction of the container 100, the two side plates 140 are positioned opposite each other along the width direction of the container 100, and the rear panel 150 and the opening 160 are positioned opposite each other along the length direction of the container 100. The first main shaft 420 extends perpendicular to the length of the container 100 and is located on one side of the energy storage cabinet 310. The energy storage cabinet 310 is electrically connected to the first photovoltaic module 500, storing the electrical energy generated by the first photovoltaic module 500. Two clearance openings 141 are provided on each side panel 140, corresponding to the first main shaft 420 and the second main shaft 620 respectively, allowing the first and second main shafts 420 to pass through. Installers can install purlins at the points where the first and second main shafts 420 and 620 extend out of the container 100, and then install the first photovoltaic module 500 or the second photovoltaic module 700 on the purlins. This allows for an unlimited number of photovoltaic modules, improving power generation efficiency. Alternatively, clearance openings 141 corresponding to the first and second main shafts 420 and 620 can be provided only on one of the two side panels 140, with the first and second main shafts extending only along one side of the container 100's length or width. This selection can be made according to actual needs, giving this application good adaptability and flexibility.
[0077] For details, please refer to Figure 6As shown, the first slewing support assembly 170 is fixedly connected to the top plate 120 of the container 100 and is used to support the first drive mechanism 410. The first slewing support assembly 170 includes a first mounting plate 171 and a first connecting plate 172. The first drive mechanism 410 is mounted on the first mounting plate 171. The first drive mechanism 410 and the first mounting plate 171 are provided with corresponding bolt holes. After the bolt passes through the corresponding bolt holes, it is tightened by a nut, thereby realizing the connection between the first drive mechanism 410 and the first mounting plate 171. One end of the first connecting plate 172 is connected to the first mounting plate 171, and the other end is fixedly connected to the top plate 120, thereby realizing the pre-installation of the first drive mechanism 410 inside the container 100. In this embodiment, to facilitate the installation of the first slewing support assembly 170, a mounting beam 180 is provided on the side of the top plate 120 near the receiving chamber 110. The first slewing support assembly 170 also includes a first top connecting plate 173, located at the end of the first connecting plate 172 away from the first mounting plate 171, and fixedly connected to the first mounting beam 180. The first top connecting plate 173 is preferably detachably connected to the mounting beam 180 via fasteners such as bolt assemblies, thereby achieving a detachable connection between the first slewing support assembly 170 and the mounting beam 180. The provision of the first top connecting plate 173 improves the convenience of connection with the mounting beam 180 while increasing the contact area between the first slewing support assembly 170 and the mounting beam 180, thereby increasing the support strength of the first slewing support assembly 170. Furthermore, each pair of first connecting plates 172 located on both sides of the first spindle 420 is connected by a first reinforcing member 174 to increase the rigidity and strength of the first slewing support assembly 170. In other embodiments, the first slewing support assembly 170 may also include only a first mounting plate 171 and a first connecting plate 172. The first drive mechanism 410 is disposed on the first mounting plate 171. One end of the first connecting plate 172 is fixed to the mounting plate 171 by welding, riveting or bolting, and the other end is fixed to the mounting beam 180 by welding, riveting or bolting, or other detachable or non-detachable methods, thereby realizing the installation of the first drive mechanism 410 inside the container 100.
[0078] The structure of the second slewing support assembly 190 is the same as that of the first slewing support assembly 170. The second slewing support assembly 190 includes a second mounting plate 191, a second connecting plate 192, a second top connecting plate 193, and a second reinforcing member 194 connecting the two second connecting plates 192. The second drive mechanism 610 is mounted on the second mounting plate 191. The second drive mechanism 610 and the second mounting plate 191 have corresponding bolt holes. Bolts pass through the corresponding bolt holes and are tightened by nuts, thereby connecting the second drive mechanism 610 and the second mounting plate 191. One end of the second connecting plate 192 is connected to the second mounting plate 191, and the other end is connected to the mounting beam 180 through the second top connecting plate 193, thereby enabling the pre-installation of the second drive mechanism 610 inside the container 100. By setting the mounting beam 180, the strength and stability of the overall structure can be improved, and the installation convenience of the first slewing support assembly 170 and the second slewing support assembly 190 can be increased.
[0079] In this embodiment, the first slewing support assembly 170 and the second slewing support assembly 190 are sequentially arranged along the length of the container 100. When the integrated photovoltaic and energy storage device is in the first state, the first slewing support assembly 170 and the second slewing support assembly 190 are symmetrically arranged relative to the energy storage cabinet 310, which is beneficial to ensuring the overall stability of the photovoltaic power generation device 200 during operation. In addition, the first photovoltaic tracking bracket 400 and the second photovoltaic tracking bracket 600 can be flexibly installed in suitable positions according to the actual needs of the spacing and installation requirements, so as to adapt to the installation requirements of mainstream tracking brackets such as flat single-axis and inclined single-axis, thereby enabling the container 100 to be suitable for containerized installation of various tracking bracket products, realizing a flexible deployment mode of "one container for multiple uses".
[0080] See Figure 6 and Figure 7 The first drive mechanism 410 includes a motor 411 and an active rotary drive mechanism. The active rotary drive mechanism includes a first housing 412, an active transmission component assembly disposed within the first housing 412, a first input shaft (not shown in the figure) driveably connected to the active transmission component assembly, and a first output shaft 413 and a second output shaft 414 driveably connected to the active transmission component assembly. The motor 411 is driveably connected to one end of the first input shaft (not shown in the figure). The first input shaft and the first output shaft 413 are perpendicular to each other. The second output shaft 414 is driveably connected to the first main shaft 420. The power of the motor 411 is transmitted to the active transmission component assembly through the first input shaft, and then the active transmission component assembly transmits the power to the first output shaft 413 and the second output shaft 414 respectively. The second output shaft 414 then transmits the power to the first main shaft 420.
[0081] See Figure 6 and Figure 8The second drive mechanism 610 includes a driven rotary drive mechanism, which comprises a second housing 611, a driven transmission component group disposed within the second housing 611, a second input shaft 612 and a third output shaft 613 connected to the driven transmission component group. The second input shaft 612 is driven by a synchronous shaft 800, and the third output shaft 613 is driven by a second main shaft 620. One end of the synchronous shaft 800 is driven by a first output shaft 413 of the active rotary drive mechanism, and the other end is driven by a second input shaft 612, thereby transmitting the power of the motor 411 to the second drive mechanism 610. The second drive mechanism 610 drives the second main shaft 620 to rotate via the third output shaft 613, thus driving the first main shaft 420 and the second main shaft 620 to rotate synchronously via a single motor 411. The active transmission component group and the driven transmission component group can be implemented through gear transmission, worm gear transmission, or other similar methods.
[0082] See Figure 1 , Figure 13 and Figure 14 The first photovoltaic tracking bracket 400 also includes a first column 430, a first column top seat 440, a first bearing seat 450, a first bearing, and multiple first purlins 460. When the photovoltaic-storage integrated device is in the first state, the first column top seat 440 is correspondingly installed on the first column 430 and located at the top of the first column 430. The first bearing seat 450 is correspondingly installed on the first column top seat 440, and the first bearing is correspondingly installed inside the first bearing seat 450. The first main shaft 420 passes through the first bearing, and the multiple first main shafts 420 are connected by a connecting... The shafts are connected end to end to form a single main shaft. Specifically, one end of the connecting member is connected to a first main shaft 420, and the other end is connected to another first main shaft 420, thereby connecting multiple first main shafts 420 end to end to form a whole. In this embodiment, there are two first columns 430, which are located on both sides of the container 100 along the width direction of the container 100. The two ends of the first main shaft 420 pass through the clearance openings 141 opened on the side plates 140 of the container 100 and are connected to the two first columns 430. In other embodiments, only one first column 430 may be provided. One end of the first main shaft 420 is located in the receiving chamber 110 of the container 100, and the other end passes through the first clearance opening 141 opened on one of the side plates 140 and is connected to the first column 430. The first purlin 460 is connected to the first main shaft 420 by known connection structures such as clamps, U-bolts, and through bolts. The first photovoltaic module 500 is connected to the first purlin 460 by fasteners such as bolts, thereby realizing the installation of the first photovoltaic module 500 on the first photovoltaic tracking bracket 400.
[0083] The second photovoltaic tracking bracket 600 also includes a second column 630, a second column top seat 640, a second bearing seat 650, a second bearing, and multiple second purlins 660. When the integrated photovoltaic and energy storage device is in the first state, the second column top seat 640 is installed on the second column 630 and located at the top of the second column 630. The second bearing seat 650 is installed on the second column top seat 640, and the second bearing is installed inside the second bearing seat 650. The second main shaft 620 passes through the second bearing, and the multiple second main shafts 620 are connected by a connecting... The shafts are connected end to end to form a single main shaft. Specifically, one end of the connecting member is connected to a second main shaft 620, and the other end is connected to another second main shaft 620, thereby connecting multiple second main shafts 620 end to end to form a whole. In this embodiment, there are two second columns 630, which are located on both sides of the container 100 along the width direction of the container 100. The two ends of the second main shaft 620 pass through the clearance openings 141 on the side panels 140 of the container 100 and are connected to the two second columns 630. In other embodiments, only one second column 630 may be provided. One end of the second main shaft 620 is located in the receiving chamber 110 of the container 100, and the other end passes through the first clearance opening 141 on one of the side panels 140 and is connected to the second column 630. The second purlin 660 is connected to the second main shaft 620 via known connection structures such as clamps, U-bolts, and through bolts. The second photovoltaic module 700 is connected to the second purlin 660 via fasteners such as bolts, thereby enabling the installation of the second photovoltaic module 700 on the second photovoltaic tracking bracket 600.
[0084] Please continue to refer to this. Figure 1 , Figure 13 and Figure 14 As shown, the photovoltaic power generation device 200 also includes a reinforcing bracket 900. In the first state, the reinforcing bracket 900 is located between the first column 430 and the second column 630. The reinforcing bracket 900 includes at least one transverse connecting rod 910. The two ends of the transverse connecting rod 910 are respectively connected to the first column 430 and the second column 630, thereby increasing the support strength of the first column 430 and the second column 630 and improving the stability of the photovoltaic-storage integrated device. In this embodiment, there are two transverse connecting rods 910. A diagonal brace 920 is also provided between the two transverse connecting rods 910, thereby further enhancing the strength of the first column 430 and the second column 630.
[0085] Please refer to Figure 4 and Figure 5As shown in the figure, the integrated photovoltaic and energy storage device further includes a distribution box 320 and an inverter 330. The inverter 330 can convert the direct current generated by the first photovoltaic module 500 and the second photovoltaic module 700 into alternating current, and the distribution box 320 is used to distribute the converted alternating current to different power consumption areas. An opening 160 is provided on one side along the length direction of the container 100, and the opening 160 communicates with the accommodation chamber 110. The distribution box 320 and the inverter 330 are arranged on one side plate 140 in the radial direction of the accommodation chamber 110 and are located in the area of the side plate 140 close to the opening 160.
[0086] In this embodiment, by arranging the distribution box 320 and the inverter 330 on the same side plate 140, it is more conducive to the wiring arrangement between the distribution box 320 and the inverter 330. At the same time, the distribution box 320 and the inverter 330 are arranged close to the opening 160, which is more conducive to the installation by installers and subsequent operation and maintenance. Considering the wiring arrangement between the inverter 330 and the energy storage cabinet 310, the distribution box 320 is closer to the position of the opening 160, and the inverter 330 is arranged on the side of the distribution box 320 away from the opening 160 and is closer to the energy storage cabinet 310.
[0087] Preferably, the distribution box 320 and the inverter 330 are located in the area of the side wall close to the top of the accommodation chamber 110, and there is a gap between the distribution box 320 and the inverter 330 and the top of the accommodation chamber 110, and they are in a position where they do not reach the top. This is convenient for installation and subsequent operation and maintenance, and at the same time, enough packing space is reserved in the container 100, with a reasonable layout and high utilization rate. If the installation positions of the distribution box 320 and the inverter 330 are too high, it is not conducive to subsequent maintenance; if the installation positions are too low, it will affect the packing space in the container 100 and is not conducive to internal packing.
[0088] Specifically, referring to Figure 9 , the inverter 330 is laterally fixed through two symmetrically distributed mounting members 340. The mounting members 340 are made of channel steel and are in a "C" shape, arranged up and down and the openings 160 of the two channel steels face away from each other. Before installing the inverter 330, the channel steel has been pre-positioned and pre-welded to the side plate 140 of the accommodation chamber 110 of the container 100. Each channel steel is provided with two fixing points, forming four equally spaced anchor nails, and each fixing point is fixedly connected to the inverter 330 with bolts, nuts, flat gaskets, spring gaskets, etc.
[0089] Relatively, the distribution box 320 is laterally fixed through two symmetrically distributed mounting members 340. The mounting members 340 are made of channel steel and are in a "C" shape, arranged up and down and the openings face away from each other. Before installing the distribution box 320, the channel steel has been pre-positioned and pre-welded to the side plate 140 of the accommodation chamber 110 of the container 100. Each channel steel is provided with two fixing points, forming four equally spaced anchor nails, and each fixing point is fixedly connected with bolts, nuts, flat gaskets, spring gaskets, etc.
[0090] See Figure 10 At the bottom of the energy storage cabinet 310, it is also fixedly supported by two symmetrically distributed mounting members 340. The mounting members 340 are made of channel steel and are in a "U" shape. The two channel steels are axially spaced along the accommodating chamber 110, and the openings of the two channel steels face away from each other. Before installing the energy storage cabinet 310, the channel steels have been pre-positioned and pre-welded to the bottom of the accommodating chamber 110 of the container 100. Each channel steel is provided with two fixed points, forming four equally spaced anchor nails, and each fixed point is fixedly connected with bolts, nuts, flat gaskets, spring gaskets, etc. Specifically, during actual assembly, the above-mentioned inverter 330, distribution box 320, and energy storage cabinet 310 are placed on the corresponding mounting members 340 and assembled with bolt assemblies.
[0091] See Figure 11 The integrated photovoltaic and energy storage device further includes an exhaust fan 350. Since electrical equipment such as the energy storage cabinet 310, inverter 330, and distribution box 320 generate a large amount of heat during operation, causing the temperature inside the container 100 to be too high, which affects the safety performance of the entire system. Therefore, in this embodiment, to avoid the temperature inside the container 100 from being too high, an exhaust fan 350 is installed on the side plate 140 of the accommodating chamber 110 where the distribution box 320 and the inverter 330 are located, which can strengthen the air convection inside the container 100 and significantly reduce the operating temperatures of the energy storage cabinet 310, inverter 330, and distribution box 320.
[0092] Among them, the exhaust fan 350 is preferably arranged close to the energy storage cabinet 310, located in the area of the side plate 140 corresponding to the energy storage cabinet 310 in the first state, and close to the top of the accommodating chamber 110, so as to better dissipate heat from the energy storage cabinet 310, distribution box 320, and inverter 330. Of course, in actual production, the exhaust fan 350 can be added by opening holes at any position in the circumferential direction of the container 100, which is not limited here, and all are within the protection scope of this application.
[0093] See Figure 4 、 Figure 12 and Figure 13The integrated photovoltaic and energy storage device also includes at least two first counterweights 101, and the top of each first counterweight 101 is provided with a connecting structure 1011. Specifically, the connecting structure 1011 can be a built-in anchor bolt assembly. In the first state, the connecting structure 1011 on the top of the first counterweight 101 can be rigidly connected to the bottom of the first column 430 or the second column 630 via threaded engagement. At this time, the first counterweight 101 can provide additional weight compensation for the photovoltaic power generation device 200, enhance wind resistance stability, ensure the balanced operation of the first photovoltaic tracking bracket 400 and the second photovoltaic tracking bracket 600, and reduce the risk of overturning. When the integrated photovoltaic and energy storage device is in the second state, the first counterweights 101 can be placed on both sides of the receiving chamber 110 along the length of the container 100, ensuring that the container 100 is force-balanced during transportation.
[0094] Further, see Figure 4 , Figure 5 and Figure 15 The accommodating chamber 110 also contains at least two second counterweights 102. The placement of the second counterweights 102 can be flexibly changed according to the force distribution of the container 100 to increase the counterweight of the container 100 and avoid uneven stress on the container 100 after transportation and installation. Especially when the integrated photovoltaic and energy storage equipment is working (i.e., in the first state), the first photovoltaic tracking bracket 400 and the second photovoltaic tracking bracket 600 are easily affected by external factors such as strong winds, which can easily cause the container 100 to resonate. At this time, the second counterweights 102 can absorb vibration energy, increase the stability of the container 100, and ensure the stability of the first photovoltaic tracking bracket 400 and the second photovoltaic tracking bracket 600 connected to it, thereby realizing the normal operation of the integrated photovoltaic and energy storage equipment. In the above embodiment, both the first counterweight 101 and the second counterweight 102 are provided with pull rings 107. The pull rings 107 are pre-embedded stainless steel pull rings, which support forklift, hoisting or manual handling, and are convenient for installation and transportation.
[0095] See Figure 5When the integrated photovoltaic and energy storage device is in the second state, the second counterweight 102 is preferably placed inside the container 100 and located on one side of the energy storage cabinet 310 along the width direction of the container 100. Meanwhile, the components of the first photovoltaic tracking bracket 400 and the second photovoltaic tracking bracket 600 (after disassembly) are located on the other side of the energy storage cabinet 310. This arrangement further ensures the force balance of the container 100 and guarantees transportation safety. In this application, by setting the first counterweight 101 and the second counterweight 102, flexible weight distribution of the container 100 can be achieved, allowing the integrated photovoltaic and energy storage device to maintain balance in both the first and second states, solving the balance problem of photovoltaic module deployment. In particular, the first counterweight 101 can also be connected to the photovoltaic power generation device during operation, providing additional weight compensation, thereby enhancing the wind resistance stability of the photovoltaic power generation device and enabling stable operation.
[0096] Specifically, see Figure 5 and Figure 16 The components of the first photovoltaic tracking bracket 400 after disassembly include a first column 430, a first column top seat 440, a first main shaft 420, a first bearing seat 450, a first bearing, and multiple first purlins 460; the components of the second photovoltaic tracking bracket 600 after disassembly include a second column 630, a second column top seat 640, a second main shaft 620, a second bearing seat 650, a second bearing, and multiple second purlins 660; because during packaging and transportation (i.e., when the photovoltaic-storage integrated equipment is in the second state), considering that packaging by functional modules can meet the needs of centralized transportation, retrieval, installation, and recycling of all materials, the components of the first photovoltaic tracking bracket 400 and the components of the second photovoltaic tracking bracket 600 after disassembly will be stored together. There are multiple first main shafts 420 and multiple second main shafts 620. In the first state, the multiple first main shafts 420 and the multiple second main shafts 620 are connected end to end to form a whole. In the second state, for ease of installation, except for a portion of the first main shaft 420 and a portion of the second main shaft 620 pre-installed on the first drive mechanism 410 and the second drive mechanism 610, the remaining first main shaft 420 and second main shaft 620 are packaged together with the first column 430 and the second column 630. Considering the relatively long length of the first column 430 and the second column 630, the first column 430, the second column 630, the reinforcing bracket 900, and the remaining first main shaft 420 and second main shaft 620 are packaged and placed along the length of the container 100. To ensure the force balance of the container 100, the first column 430, the second column 630, the reinforcing bracket 900, and the remaining first main shaft 420 and second main shaft 620 are packaged as a whole and placed on one side of the energy storage cabinet 310 along the width of the container 100. The second counterweight 102 is placed on the other side of the energy storage cabinet 310 along the width of the container 100.
[0097] Further, see Figure 5 When the photovoltaic-storage integrated equipment is in the second state, the accommodating chamber 110 forms a first placement area along the length of the container 100 on the side of the energy storage cabinet 310 near the opening 160. A first packing box 103 is placed in the first placement area. The first packing box 103 is used to store the first photovoltaic module 500 and the second photovoltaic module 700.
[0098] See Figure 5 and Figure 17 To further balance the forces acting on the container 100 during transport, when the integrated photovoltaic and energy storage device is in its second state, the receiving chamber 110 forms a second placement area along the length of the container 100 on the side of the energy storage cabinet 310 away from the opening 160. This second placement area is located on the side of the first counterweight 101 away from the first placement area, and a second packing box 104 is placed there. The second packing box 104 is used to store purlins (first purlin 460 and second purlin 660). During packing, utilizing the structural characteristics of the purlins, the purlins are neatly placed inside the second packing box 104, and the main shaft connector is placed in the gaps between the purlins. At this time, the main shaft connector, purlins, and second packing box 104 will mutually limit each other, ensuring transport stability while maximizing space utilization and reducing space waste.
[0099] Specifically, the container 100 is hinged with a door 105 at the opening 160 and a cover 106 at the clearance opening 141, which provides good protection for the internal parts of the container 100 during transportation, preventing them from being exposed to wind and rain. This embodiment integrates a rapid positioning and installation system for the energy storage cabinet 310, inverter 330, and distribution box 320 by pre-installing modular mounting components 340 inside the container 100. This system is simple in structure and easy to install, enabling the energy storage cabinet 310, inverter 330, and distribution box 320 to be installed and used immediately, and disassembled as needed, shortening installation time. Furthermore, during actual transportation, the already installed inverter 330 and distribution box 320 do not need to be disassembled again. The photovoltaic modules and their accessories can be directly packaged according to functional modules and placed in the receiving chamber 110, achieving a reduction in frequent disassembly and assembly, which is beneficial for the overall modular transportation of the container 100. The energy storage cabinet 310 is in an uninstalled state during transportation and is only installed after transportation is completed.
[0100] In the above embodiments, the first main shaft 420 and the second main shaft 620 extend along the width direction of the container 100 and are perpendicular to the length direction of the container 100. The energy storage cabinet 310 is set close to one side along the width direction of the container 100. In other embodiments, depending on the application environment of the project site, the first main shaft 420 and the second main shaft 620 can be extended along the length direction, and / or the energy storage cabinet 310 can be set close to one side along the length direction of the container 100. It is understood that the setting direction of the corresponding clearance opening 140, slewing support components, etc. can be adjusted accordingly to meet the installation requirements.
[0101] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0102] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
