[0043] Photovoltaic storage integrated equipment refers to a comprehensive energy device that integrates photovoltaic power generation devices and energy storage devices. On this basis, charging equipment can be further integrated to form a photovoltaic storage and charging integrated equipment. These integrated devices can be deployed off-grid and have the function of peak shaving and valley filling, and have a wide range of application scenarios. However, due to the different application scenarios, high requirements are also placed on the flexibility of equipment configuration, transportation, installation, and transfer. This application specifically proposes a container-type photovoltaic bracket and photovoltaic storage integrated equipment, which is modularly set up, which is not only convenient for configuration and expansion, but also for transportation and installation. After installation and transfer, the installation accuracy of core components such as drive devices and main shafts can be guaranteed, which not only saves costs but also ensures the installation quality of the system.

[0044] like Figure 1 As shown, the present application provides a container-type photovoltaic bracket 100, which is used to form a photovoltaic storage integrated device in combination with a photovoltaic bracket outside the box. Figure 2 As shown, the integrated photovoltaic and storage device includes a container-type photovoltaic bracket 100, at least one first photovoltaic bracket 200 and at least one photovoltaic module 300. The device can be set up off-grid, independently realizing the integrated photovoltaic and storage or integrated photovoltaic and storage and charging functions, and is suitable for use in remote areas or emergency applications. Therefore, the device is required to be easy to transport and transfer, and can be quickly installed at the installation site. According to different needs, it must also be easy to expand. This places high demands on the modularity and transportation, installation, expansion, and transfer capabilities of the equipment. To this end, the present application provides a container-type photovoltaic bracket 100 and an integrated photovoltaic and storage device based on the container-type photovoltaic bracket. The following specific embodiments illustrate how the present application solves the above-mentioned technical problems.

[0045] like Figure 1FIG. 1 shows an embodiment of a containerized photovoltaic support 100. In this embodiment, the containerized photovoltaic support 100 includes a box-type storage device 110, a first drive device 130, and a first spindle 160. The first spindle 160 extends outward from the box-type storage device 110 along the width direction Y-Y' of the box-type storage device 110, thereby significantly extending the length of the containerized photovoltaic support 100 and increasing power generation. The box-type storage device 110 includes a accommodating cavity 199 and at least one opening 150, which communicates with the accommodating cavity 199. The first drive device 130 is disposed within the accommodating cavity 199, and the first spindle 160 is disposed corresponding to one of the openings 150. Within the accommodating cavity 199, the first spindle 160 is transmission-connected to the first drive device 130, enabling the first drive device 130 to drive the first spindle 160 in rotation. The opening 150 can be created on-site or pre-existing in the box-type storage device 110, as described later in this application. In other embodiments, the first main shaft 160 may also extend outward from the box-type storage device 110 along the length direction XX′ of the box-type storage device 110 , which can be selected according to the actual environment of the project site and is within the protection scope of this application.

[0046] In the above setting, the box-type storage device 110 is not only a structural component for installing other components, but also can be used as a transportation carrier. The installation of core components can be completed before leaving the factory, thus realizing modularization, facilitating transportation, installation, and transfer. Moreover, by selecting suitable photovoltaic brackets on site to cooperate with them, it is easy to expand.

[0047] The box-type storage device 110 serves two purposes: first, it houses the intelligent tracking drive system, including core components such as the first drive device 130 and the first spindle 160; second, it serves as a support structure for the first spindle 160, thereby replacing some photovoltaic support structures such as photovoltaic columns. The box-type storage device 110 is preferably constructed from a modified ISO668 standard container, preferably a 20-foot standard container. This container-type storage device 110 easily complies with land and sea transport standards, eliminating the need for additional packaging and can be directly delivered to a transport company for long-distance transport. Upon arrival at the installation site, it can be directly installed without any packaging, disassembly, or adjustments.

[0048] Since the installation requirements of the first main shaft 160 and the first drive device 130 are relatively high, it is preferred to complete the installation in the production workshop to ensure installation efficiency and installation accuracy; at the same time, since the box-type storage device 110 is easy to transport, it not only saves the packaging and transportation of devices such as the first main shaft 160 and the first drive device 130, but also ensures transportation safety.

[0049] like Figure 2 、 Figure 9 and Figure 11As shown, in some embodiments, the container-type photovoltaic support 100 further includes a second drive device 140, a second main shaft 165 and a synchronization shaft 190. The second drive device 140 is also disposed in the accommodating cavity 199, and the second main shaft 165 is transmission-connected to the second drive device 140 and is arranged parallel to the first main shaft 160. The second main shaft 165 is also arranged corresponding to an opening 150. The two ends of the synchronization shaft 190 are respectively transmission-connected to the first drive device 130 and the second drive device 140. For details, please refer to Figure 13 As shown, the first drive device 130 includes a motor 131 and an active rotary drive mechanism. The active rotary drive mechanism includes a first housing 132, an active transmission assembly disposed within the first housing 132, a first input shaft drivingly connected to the active transmission assembly, and first and second output shafts 134, 135, respectively, drivingly connected to the active transmission assembly. The motor 131 is drivingly connected to one end of the first input shaft (not shown), the first input shaft and the first output shaft 134 being perpendicular to each other. The second output shaft 135 is drivingly connected to the first main shaft 160, and the first output shaft 134 is drivingly connected to the synchronous shaft 190. Specifically, the power of the motor 131 is transmitted via the first input shaft to the active transmission assembly, which then transmits the power to the first and second output shafts 134, 135, respectively. The first output shaft 134 transmits the power to the second drive device 140 via the synchronous shaft 190, while the second output shaft 135 transmits the power to the first main shaft 160.

[0050] Please refer to Figure 14As shown, the second drive device 140 includes a driven rotary drive mechanism, which includes a second housing 141, a driven transmission member group arranged in the second housing 141, a second input shaft 142 connected to the driven transmission member group, and a third output shaft 143 connected to the driven transmission member group. The second input shaft 142 is connected to the synchronizing shaft 190, and the third output shaft 143 is connected to the second main shaft 165. One end of the synchronizing shaft 190 is connected to the first output shaft 134 of the active rotary drive mechanism, and the other end is connected to the second input shaft 142, thereby transmitting the power of the motor 131 to the second drive device 140. The second drive device 140 drives the second main shaft 165 to rotate through the third output shaft 143, thereby driving the first main shaft 160 and the second main shaft 165 to rotate synchronously through one motor 131. The active transmission component group and the passive transmission component group can be implemented through gear transmission, worm gear transmission, etc. It is understandable that the active transmission component group of the first drive device 130 and the passive transmission component group of the second drive device 140 can also adopt relevant modules in the prior art, such as a parallel drive device with application number 202222152292.3, a drive device with application number 202411101394.X, or a transmission shaft mounting structure and parallel drive device with application number 202320455699.5.

[0051] The use of a box-type storage device 110 based on a standard container is the preferred method of this application, which can take advantage of the standardization advantage of standard containers and the price advantage of standard products. However, depending on the specific situation, other box-type storage devices 110 suitable for transportation can also be used as long as they have a similar structure. Figure 8 As shown, the box-type storage device 110 includes a top panel 111, a bottom panel 112, two side panels 113, a rear panel 115, and a set of side doors 114, forming a rectangular box. The top panel 111 and the bottom panel 112 are arranged opposite each other along the height direction ZZ' of the box, the two side panels 113 are arranged opposite each other along the width direction YY' of the box, and the rear panel 115 and the side doors 114 are arranged opposite each other along the length direction XX' of the box. In this embodiment, an opening 150 is provided on at least one side panel 113, and each side panel 113 has two openings 150, corresponding to the first main axis 160 and the second main axis 165, respectively. In other embodiments, the side panels 113 on one or both sides of the box-type storage device 110 may be eliminated, so that a single opening 150 communicating with the accommodating chamber 199 is formed between the side door 114 and the rear panel 115. In this embodiment, the bottom plate 112 is adapted to dock with a transport vehicle and the first pre-set mounting position 401. The side door 114, when opened, allows access for internal modules and assembly personnel. When closed, it forms a sealed, locked state suitable for long-distance transportation. The top plate 111 is suitable for hoisting and, with specialized fasteners, can also accommodate additional photovoltaic modules 300.

[0052] In the above embodiment, the box-type storage device 110 is provided with openings 150 on both sides, and the two first main shafts 160 and the two second main shafts 165 correspond to the openings 150 on both sides respectively. However, in other embodiments, such as Figure 5 and Figure 6 As shown, in some application scenarios, the photovoltaic assembly 300 and the column 211 only need to be set on one side of the container-type photovoltaic support 100. In this case, the box-type storage device 110 only needs to be provided with an opening 150 on the corresponding side.

[0053] In addition, in some embodiments, the opening 150 can also be achieved by removing a side panel 113, that is, the box-type storage device 110 is set to an incompletely closed form to facilitate installation, which is suitable for situations where long-distance sea transportation is not required or waterproof and dustproof are not required during transportation.

[0054] In this embodiment, in order to realize the installation of the first driving device 130 and the second driving device 140, refer to Figures 10 to 13 , the container-type photovoltaic support 100 also includes a first steel beam 181 and a swivel seat 170. The first steel beam 181 is fixed to the top of the box-type storage device 110, the swivel seat 170 is fixed to the first steel beam 181, and the first drive device 130 is fixed to the swivel seat 170. The first steel beams 181 are preferably channel steels and are arranged in pairs, and are preferably welded to the top plate 111. In this embodiment, the number of first steel beams 181 is two, and the two first steel beams 181 are parallel to each other and parallel to the top plate 111, and their openings are back to back and aligned. The first steel beam 181 is preferably welded to the top plate 111, but can also be fixed by a plurality of bolt assemblies, wherein the bolt connection is located between the reinforcing ribs of the top plate 111. In addition, in other embodiments, the first steel beam 181 can be omitted and the slewing seat 170 can be directly fixed to the top plate 111. In this embodiment, the advantage of providing the first steel beam 181 is that it is convenient to ensure that the first drive device 130 and the second drive device 140 are located at the same installation height. At the same time, the slewing seat 170 and the first steel beam 181 are detachably connected by bolts, which facilitates the subsequent maintenance and replacement of the first drive device 130 and / or the second drive device 140.

[0055] The swivel seat 170 includes a seat plate 172 and connecting columns 173. The first drive unit 130 is fixed to the seat plate 172. The first drive unit 130 and the seat plate 172 are provided with corresponding bolt holes. Bolts pass through the corresponding bolt holes and are tightened with nuts to achieve the connection between the first drive unit 130 and the seat plate 172. The ends of the connecting columns 173 are respectively fixedly connected to the seat plate 172 and the first steel beam 181.

[0056] In some embodiments, the swivel seat 170 further includes a top connecting plate 171, which is provided at one end of the connecting column 173 away from the seat plate 172 and is fixedly connected to the first steel beam 181. The top connecting plate 171 is preferably detachably connected to the first steel beam 181 by fasteners such as a bolt assembly, thereby achieving a detachable connection between the swivel seat 170 and the first steel beam 181. The provision of the top connecting plate 171 increases the contact area between the swivel seat 170 and the first steel beam 181 while facilitating installation, thereby increasing the supporting strength of the swivel seat 170. In addition, the connecting column 173 is preferably an angle steel with the top angle facing inward, but an I-beam or other forms of profiles may also be used. Reference Figure 12 , each pair of connecting columns 173 located on both sides of the first main shaft 160 is further connected by a reinforcement member 174 to increase the rigidity and strength of the swivel seat 170. Figure 11 and Figure 12 After installation, the first main shaft 160 is parallel to the top plate 111 and has a predetermined height relative to the bottom docking plane of the bottom plate 112 of the box-type storage device 110. It is understood that in other embodiments, the swivel seat 170 may include only a seat plate 172 and connecting posts 173. The connecting posts 173 may also be two, three, five, or another number. The first drive device 130 is disposed on the seat plate 172. One end of the connecting post 173 is secured to the seat plate 172 by welding, riveting, or bolting, and the other end is secured to the first steel beam 181 by welding, riveting, or bolting, or other detachable or non-detachable means, thereby enabling the first drive device 130 to be installed within the box-type storage device 110. In this embodiment, the provision of the top connecting plate 171 increases the structural strength of the swivel seat 170 and facilitates its connection to the first steel beam 181.

[0057] The second drive unit 140 is installed in a similar manner to the first drive unit 130 and can share the same first steel beam 181 with the first drive unit 130. In other embodiments, the first steel beam 181 for mounting the first drive unit 130 and the first steel beam 181 for mounting the second drive unit 140 can be separately provided. That is, the first steel beams 181 corresponding to the two drive units can be integral or separate. It will be understood that the number of swivel seats 170 depends on the number of first and second drive units 130, 140, with each swivel seat 170 corresponding to a drive unit. In this embodiment, there are one first and one second drive unit 130, 140, respectively, and two swivel seats 170 corresponding to the first drive unit 130, 140. The two swivel seats 170 are spaced apart along the length of the two first steel beams 181.

[0058] In the illustrated embodiment, please refer to Figure 11As shown, the container-type photovoltaic bracket 100 includes two first main shafts 160 and two second main shafts 165. The first drive device 130 is transmission-connected to the two first main shafts 160 extending in opposite directions, and the first main shaft 160 is transmission-connected to the second output shaft 135 of the first drive device 130, so as to rotate synchronously under the drive of the second output shaft 135; the second drive device 140 is also transmission-connected to the two second main shafts 165 extending in opposite directions, and the second main shaft 165 is transmission-connected to the third output shaft 143 of the second drive device 140, so as to rotate synchronously under the drive of the third output shaft 143.

[0059] Please continue to refer to Figures 9 to 15 As shown, the connection between the synchronizing shaft 190 and the first drive device 130 and the second drive device 140 is specifically achieved through the following structure. In this embodiment, the synchronizing shaft 190 includes an inner tube 192 and an outer tube 191. Each of the inner tube 192 and the outer tube 191 includes a hollow cavity. One end of the inner tube 192 extends into the cavity at one end of the outer tube 191 and is telescopically movable within the cavity of the outer tube 191. The other end of the inner tube 192 is transmission-connected to the second drive device 140 via a coupling 193. One end of the outer tube 191 is movably connected to the inner tube 192, and the other end is transmission-connected to the first drive device 130 via another coupling 193. By configuring the synchronizing shaft 190 with the inner tube 192 and the outer tube 191 in a telescopic connection, it not only facilitates installation but also accommodates installation errors between the first drive device 130 and the second drive device 140, ensuring smooth installation of the synchronizing shaft 190. One end of the coupling 193 is connected to the inner tube 192 or the outer tube 191 by a fastener such as a bolt, and the other end of the coupling 193 is connected to the first output shaft 134 or the second input shaft 142 by a fastener such as a bolt, thereby realizing the transmission connection between the synchronizing shaft 190 and the first drive device 130 and the second drive device 140. In this embodiment, the coupling 193 includes two U-shaped parts, and the two U-shaped parts are arranged in one piece. In other embodiments, the coupling 193 can also be in the form of a universal joint, thereby increasing the flexibility of the synchronizing shaft 190 during the transmission process.

[0060] Please refer to Figures 2 to 20 As shown, the present application also discloses a photovoltaic storage integrated device, including a container-type photovoltaic bracket 100, a first photovoltaic bracket 200 and a photovoltaic assembly 300 according to any of the embodiments described above, the first photovoltaic bracket 200 includes a third main shaft 260, and the third main shaft 260 is connected to the first main shaft 160; or, the third main shaft 260 is integrally arranged with the first main shaft 160, and the photovoltaic assembly 300 is installed to the third main shaft 260 and / or the first main shaft 160.

[0061] In this embodiment, the first main shaft 160 and the third main shaft 260 are provided separately. The third main shaft 260 passes through the opening 150 and is connected to the first main shaft 160 through a coupling device. The coupling device includes a connecting member and a fastening bolt. One end of the connecting member is covered on the outside of the third main shaft 260 and the other end is covered on the outside of the first main shaft 160. The fastening bolt connects the two ends of the connecting member to the third main shaft 260 and the first main shaft 160 respectively, thereby realizing the connection between the third main shaft 260 and the first main shaft 160. The third main shaft 260 is connected to the first main shaft 160 at the opening 150 opened on the box-type storage device 110. The third main shaft 260 and the first main shaft 160 together constitute the first main shaft assembly. The first driving device 130 is used to drive the first main shaft assembly, so that Figure 3 As shown, the angle of the photovoltaic module 300 can be adjusted to achieve intelligent photovoltaic tracking. The box-type storage device 110 and the first photovoltaic bracket 200 together constitute the support for the first main shaft assembly, allowing the first main shaft assembly to rotate under the drive of the first drive device 130. The above arrangement not only facilitates installation, but the solid box structure of the container itself replaces some columns, simplifying the structure of the photovoltaic bracket and saving costs. In addition, the weight of the container itself, as well as the weight of the built-in first drive device 130 and other modules, all serve as counterweights, significantly increasing the mechanical stability of the entire device.

[0062] In this embodiment, the integrated photovoltaic and storage device also includes a second photovoltaic bracket 250, and the second photovoltaic bracket 250 includes a fourth main shaft 265. The fourth main shaft 265 is arranged parallel to the third main shaft 260 and is connected to or integrated with the second main shaft 165. The fourth main shaft 265 and the third main shaft 260 together constitute the second main shaft assembly, and the second drive device 140 is used to drive the second main shaft assembly so that the second main shaft assembly rotates under the drive of the second drive device 140. It can be understood that the fourth main shaft 265 and the second main shaft 165 can be separately arranged and connected by a coupling device. The structure and connection method of the coupling device are the same as the connection method of the third main shaft 260 and the first main shaft 160, and will not be repeated here. In another embodiment, the third main shaft 260 and the first main shaft 160, the fourth main shaft 265 and the second main shaft 165 can also be arranged integrally.

[0063] like Figure 9As shown, in some embodiments, the first main shaft 160 and the second main shaft 165 are both located within the accommodating cavity 199, that is, both are entirely located within the box-type storage device 110, thereby making the container-type photovoltaic support 100 easy to transport. However, in other embodiments, one or both of the first main shaft 160 and the second main shaft 165 can extend out of the accommodating cavity 199 through the opening 150 and extend a certain length to facilitate connection with the third main shaft 260 or the fourth main shaft 265, or even omit the third main shaft 260 and the fourth main shaft 265, and install the photovoltaic assembly 300 on the externally extended first main shaft 160 or the second main shaft 165. In this case, the first main shaft 160 or the second main shaft 165 can also be installed on site instead of being pre-installed before transportation.

[0064] Figure 2 and Figure 3 The figure shows a preferred embodiment of the photovoltaic storage device of the present application, which includes two rows of photovoltaic modules 300 arranged on both sides of the container-type photovoltaic support 100. Figures 4 to 6 As shown, other embodiments of the present application may also include only two rows of photovoltaic modules 300 arranged on one side of the container-type photovoltaic support 100. In other embodiments, only one row or more than two rows of photovoltaic modules 300 may be included, and multiple container-type photovoltaic supports 100 may be provided, thereby achieving the technical effect of flexible configuration and easy expansion of the present application.

[0065] Figure 7 The diagram schematically illustrates a first preset mounting position 401 and a second preset mounting position 402, where the first preset mounting position 401 is used to mount the containerized photovoltaic rack 100, and the second preset mounting position 402 is used to mount the first photovoltaic rack 200 and / or the second photovoltaic rack 250. The first preset mounting position 401 and the second preset mounting position 402 should be understood to refer to any mounting structure that can interface with the containerized photovoltaic rack 100 and the first photovoltaic rack 200 or the second photovoltaic rack 250, respectively, such as a flat surface, paved surface, or bracket suitable for securing or placing the containerized photovoltaic rack 100. Therefore, the diagram uses a double-dash line frame for adaptive representation.

[0066] In some embodiments, as Figure 16 and Figure 18 As shown, the first photovoltaic support 200 includes a counterweight base 220 , and the column 211 of the first photovoltaic support 200 is fixed to the counterweight base 220 .

[0067] Specifically, if Figure 18As shown, the counterweight base 220 includes a base counterweight block 221, a lifting ring 222, and a bolt 223. The lifting ring 222 and the bolt 223 are pre-buried in the base counterweight block 221. The column 211 is fixed to the base counterweight block 221 by means of the bolt 223. A groove 224 is left at the top of the base counterweight block 221, so that the base counterweight block 221 with the lifting ring 222 and the bolt 223 pre-buried can still be stacked for easy transportation. By setting up the counterweight base 220, there is no need for piling, which reduces construction, saves costs, improves installation efficiency, and realizes the self-stabilizing installation of the integrated photovoltaic and storage equipment.

[0068] In some embodiments, the third main shaft 260 and the first main shaft 160 can be integrated and installed on site. The first main shaft 160 extending outside the box mentioned above can be considered to include the third main shaft 260. In this case, the photovoltaic module 300 can be installed on the third main shaft 260, the first main shaft 160, or both. In other words, the first main shaft assembly can have multiple implementations: for example, Figure 9 The first main shaft 160 shown in the figure is located inside, while the third main shaft 260 is located outside, and the photovoltaic module 300 is installed on the third main shaft 260; for example, the third main shaft 260 and the first main shaft 160 are an integrated first main shaft assembly, one end of the first main shaft assembly is connected to the first drive device 130, and the other end is connected to the column 211, and the photovoltaic module 300 is installed on the first main shaft assembly; in addition, the first main shaft 160 can extend out of the box for a certain distance and then be connected to one end of the third main shaft 260 through a connecting structure, the other end of the third main shaft 260 is installed on the column 211, and the photovoltaic module 300 is installed on the third main shaft 260, the part of the first main shaft 160 extending out of the box and the connecting structure.

[0069] like Figure 16 and Figure 19 As shown, in some embodiments, the first photovoltaic support 200 and the second photovoltaic support 250 both include a counterweight base 220, a column 211, a column top seat 212, and a purlin 230. The column 211 is fixed to the counterweight base 220, and the third main shaft 260 and the fourth main shaft 265 are respectively installed on the top of the column 211 through the column top seat 212. The column top seat 212 is provided at the upper end of the column 211. A main shaft bearing 213 is also provided on the column top seat 212. One end of the third main shaft 260 or the fourth main shaft 265 passes through the corresponding main shaft bearing 213, thereby achieving connection with the column 211. The purlin 230 is fixed to the third main shaft 260 and the fourth main shaft 265, and the photovoltaic module 300 is fixed to the purlin 230. As shown Figure 17 As shown, the photovoltaic assembly 300 is fixed to the third main shaft 260 and the fourth main shaft 265 through the purlin 230 and the clamp 231 .

[0070] When multiple rows of photovoltaic components 300 are set, multiple photovoltaic brackets located outside the box need to be set. In this embodiment, the two rows of columns 211 of the first photovoltaic bracket 200 and the second photovoltaic bracket 250 can be connected by a reinforcing bracket 240. Multiple columns 211 and reinforcing brackets 240 can also constitute a pre-assembled assembly. The reinforcing bracket 240 includes at least one transverse connecting rod 241, and the two ends of the transverse connecting rod 241 are respectively connected to the corresponding columns 211 of the first photovoltaic bracket 200 and the second photovoltaic bracket 250, thereby increasing the supporting strength of the column 211 and improving the stability of the integrated photovoltaic storage device. In this embodiment, the number of transverse connecting rods 241 is two, and an oblique rod 242 is further provided between the two transverse connecting rods 241 to further enhance the strength of the supporting column 211. When the reinforcing bracket 240 is provided, as Figure 3 and Figure 19 As shown, an avoidance gap 201 is left between the two photovoltaic components 300 on both sides of the reinforcing bracket 240 to prevent the photovoltaic components 300 from hitting the reinforcing bracket 240 when rotating.

[0071] The column top seat 212 is configured to be suitable for adjusting the height of the main shaft bearing 213 and / or the angle of the axis of the main shaft bearing 213 in the vertical plane. The main shaft bearing 213 is preferably a polymer bearing. Figure 20 As shown, in one embodiment, the column top seat 212 is provided with a pair of arcuate waist holes 2121 and a pair of circular holes 2122. The centerline of the arcuate waist holes 2121 coincides with the centerline of the circular holes 2122, making the angle of the column top seat 212 adjustable, thereby allowing the axis of the spindle bearing 213 to be adjusted within a vertical plane, thereby adjusting the angle of the third spindle 260. The top of the column 211 is provided with multiple pairs of vertically arranged height adjustment holes 2111. The arcuate waist holes 2121 and the circular holes 2122 are adapted to mate with any pair of height adjustment holes 2111. The column top seat 212 is secured to the column 211 via fasteners, so that the height adjustment holes 2111, the arcuate waist holes 2121, and the circular holes 2122 can be used to adjust the height of the spindle bearing 213. Alternatively, the height of the spindle bearing 213 can be adjusted by placing a gasket between the spindle bearing 213 and the column top seat 212. The position of the main shaft bearing 213 in the direction horizontally and perpendicular to the third main shaft 260 can be adjusted through the long waist hole 2123 on the column top seat 212.

[0072] In this embodiment, reference Figure 9The photovoltaic and storage integrated device also includes an energy storage system 101 and an inverter 103. The photovoltaic module 300 is electrically connected to the inverter 103. The inverter 103 converts the direct current of the photovoltaic module 300 into alternating current. The energy storage system 101 includes a battery pack, which is electrically connected to the inverter or photovoltaic module to store electrical energy. In this embodiment, the photovoltaic integrated device also includes a distribution box 102, a control device 104, an exhaust fan 105 and a counterweight 106. The distribution box 102 is used for power distribution, protection, control and monitoring. The control device 104 is set on the first main shaft 160 through a clamp and is electrically connected to the motor 131, so as to control the rotation angle of the photovoltaic module 300; the exhaust fan 105 has a heat dissipation effect on the box-type storage device 110, thereby reducing the internal temperature of the box-type storage device 110 and ensuring the normal operation of each module; the counterweight block 106 can be placed directly on the bottom plate 112. The setting of the counterweight block 106 makes the box-type storage device 110 evenly stressed as a whole, preventing problems such as uneven overall force during operation that may cause damage to the container.

[0073] The above modules are preferably arranged in a box-type storage device 110, wherein the energy storage system 101 includes an energy storage cabinet and a battery pack. The energy storage system 101 can be completely pre-installed in the container-type photovoltaic support 100, or the energy storage cabinet can be pre-installed and the battery pack can be installed at the installation site. Figure 11 As shown, the control device 104 can be mounted on the first main shaft 160 via a clamp. By placing electrical equipment such as the energy storage system 101, the control device 104, the distribution box 102, the inverter 103, and the charging device in the box-type storage device 110, dust and water can be effectively prevented, thereby extending the service life of the electrical equipment.

[0074] In order to facilitate the installation of each built-in module in the container-type photovoltaic support 100, Figure 9 and Figure 10 As shown, the box-type storage device 110 can be modified from a standard container to include a second steel beam 182 for mounting the energy storage system 101, a third steel beam 183 for mounting the inverter 103, and a fourth steel beam 184 for mounting the distribution box 102. These steel beams are preferably channel steel, but other steel profiles or aluminum profiles may also be used. In other embodiments, the first steel beam 181, the second steel beam 182, the third steel beam 183, and the fourth steel beam 184 may also have other cross-sectional shapes, such as H-shaped steel, I-shaped steel, or angle steel. This application does not limit the cross-sectional shape of the corresponding steel beams, as long as they can achieve the installation of the corresponding built-in modules.

Various obvious changes, readjustments and substitutions can be made without departing from the concept of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification.
