[0002] In the related art, most of the foldable photovoltaic devices rely on manual cooperation with auxiliary machinery to deploy the foldable photovoltaic devices. In scenarios of rapid deployment of emergency power supplies (such as the construction requirements of temporary off-grid photovoltaic power stations in field command centers, disaster area emergency power supply networks, and power supply for maritime event venues, etc.), the existing solutions have the following pain points: relying on a large number of on-site operators, requiring operators to have high professionalism, needing to invest in large auxiliary machinery and having insufficient flexibility and mobility.

[0080] Hereinafter, the specific embodiments of the present application will be described in more detail with reference to the accompanying drawings, which show representative embodiments of the present application and do not limit the present application.

[0081] Traditional photovoltaic energy storage systems or photovoltaic power generation systems usually adopt fixed installations, resulting in poor deployment flexibility. Most existing foldable photovoltaic devices rely on manual operation, with low unfolding efficiency. The energy storage device and the photovoltaic device are separated, leading to high transportation and maintenance costs. When assembling, a large number of cables need to be assembled on-site by technicians, requiring a large number of personnel and time on-site. The installation auxiliary equipment needs to occupy the surrounding site, with poor convenience and mobility. It cannot meet the scenario requirements of emergency power supplies and off-grid power supply in the wild. Therefore, there is an urgent need for an integrated photovoltaic energy storage microgrid container that can be deployed by a small number of personnel, can be used as a plug-and-play device after deployment, and has intelligent charge and discharge switching and multiple safety protections.

[0082] To at least partially solve the above problems, the present application provides a photovoltaic container. The photovoltaic container can be a photovoltaic power generation container, a photovoltaic energy storage container, or other containers with photovoltaic devices. A photovoltaic power generation container can be understood as a container that only has the function of photovoltaic power generation without the function of electricity storage. A photovoltaic energy storage container can be understood as a container that has the function of photovoltaic power generation and the function of electricity storage. The photovoltaic container includes a container and an automatically retractable and deployable photovoltaic device. The automatically retractable and deployable photovoltaic device is adapted to be connected to the chassis 106 of the container 100. The automatically retractable and deployable photovoltaic device is the photovoltaic device 110 described below.

[0083] The purpose of the present application is to solve the problems of low manual deployment efficiency and long installation time at the deployment project site, large floor area caused by the separate design of the energy storage system and the photovoltaic device, and poor coordination such as the need for civil engineering cooperation. Now, this problem is solved by technical methods such as safe transportation of the container, automatic laying of photovoltaic panels, and integration of the power generation device and the energy storage device. The photovoltaic container of the present application is a photovoltaic power generation system with an automatic unfolding function and an integrated energy storage management device, suitable for scenarios such as emergency power supplies, off-grid power supply, and field operations.

[0084] Refer to Figures 1 to 20 According to an embodiment of the present application, the photovoltaic container includes a container 100, a photovoltaic device 110, and an energy storage device 160.

[0085] The container 100 includes a chassis 106, side walls 108, a top plate 107, and a partition wall 103 located inside the container 100. Inside the container 100, there are photovoltaic cabins 101 and energy storage cabins 102 arranged at intervals along the length direction D1 of the container 100. The photovoltaic cabins 101 and the energy storage cabins 102 are separated by the partition wall 103. On the side of the container 100 along the width direction D2 of the container 100, there is an openable and closable photovoltaic cabin door 104. The photovoltaic cabin door 104 is arranged corresponding to the photovoltaic cabin 101. At one end of the container 100 along the length direction D1 of the container 100, there is an openable and closable energy storage cabin door 105. The energy storage cabin door 105 is arranged corresponding to the energy storage cabin 102.

[0086] The photovoltaic device 110 includes a photovoltaic panel assembly 120, a guide rail assembly 130, and a retracting and deploying drive assembly 140. The guide rail assembly 130 and the retracting and deploying drive assembly 140 each have a disassembled state and an assembled state. Here, the disassembled state can be understood as that the guide rail assembly 130 and the retracting and deploying drive assembly 140 can each be disassembled into several modular independent structures. Here, the assembled state can be understood as that the guide rail assembly 130 and the retracting and deploying drive assembly 140 have each completed the assembly of each modular independent structure and are connected to the container 100 when on-site deployment is completed. The guide rail assembly 130 and the retracting and deploying drive assembly 140 in the disassembled state are adapted to be placed in the photovoltaic cabin 101. The guide rail assembly 130 and the retracting and deploying drive assembly 140 in the assembled state extend out of the external of the photovoltaic cabin 101 along the width direction D2 of the container 100, so as to be adapted for the photovoltaic panel assembly 120 to be slidably connected to the guide rail assembly 130 along the width direction D2 of the container 100. The retracting and deploying drive assembly 140 is drivingly connected to the photovoltaic panel assembly 120 to be able to drive the photovoltaic panel assembly 120 to move, so that the photovoltaic panel assembly 120 can be switched between the use state and the storage state. The photovoltaic panel assembly 120 in the use state moves out of the external of the photovoltaic cabin 101 and unfolds. The photovoltaic panel assembly 120 in the storage state moves into the photovoltaic cabin 101 and folds.

[0087] The energy storage device 160 is provided in the energy storage cabin 102. The energy storage device 160 is electrically connected to the photovoltaic device 110 to be adapted to store electric energy.

[0088] After the photovoltaic cabin door 104 is opened, the photovoltaic panel assembly 120, the guide rail assembly 130, and the retracting and deploying drive assembly 140 can be deployed out of the photovoltaic cabin 101, or the photovoltaic panel assembly 120, the guide rail assembly 130, and the retracting and deploying drive assembly 140 can be stored in the energy storage cabin 102 in the photovoltaic cabin 101 for transportation. In the state where both the photovoltaic cabin door 104 and the energy storage cabin door 105 are closed, the whole container can be transported.

[0089] According to the photovoltaic container of the present application, since the guide rail assembly 130 and the retracting and deploying drive assembly 140 can be accommodated in the photovoltaic cabin 101 in the disassembled state, and the photovoltaic panel assembly 120 is located in the photovoltaic cabin 101 in the storage state, and the energy storage device 160 is provided in the energy storage cabin 102, the integration of the photovoltaic device 110 and the energy storage device 160 in the container 100 can be realized, thereby reducing the transportation and maintenance costs. Moreover, since the photovoltaic panel assembly 120 can be driven by the retracting and deploying drive assembly 140 to be switched between the use state and the storage state when the guide rail assembly 130 and the retracting and deploying drive assembly 140 are in the assembled state, the on-site deployment difficulty can be effectively reduced and the on-site deployment efficiency can be improved.

[0090] The above-mentioned photovoltaic device 110 may also be referred to as an automatic retractable photovoltaic device. First, the automatic retractable photovoltaic device according to some embodiments of the present application will be elaborated in detail below.

[0091] Referring to Figures 1 to 20 , the photovoltaic panel assembly 120 includes a plurality of cascaded photovoltaic panel members 121. The lower part of the photovoltaic panel member 121 has a guide wheel member and a traveling sprocket 129. The guide rail assembly 130 extends along a preset guiding direction. The guide rail assembly 130 is adapted to be disposed below the photovoltaic panel assembly 120 and connected to the guide wheel member to guide the photovoltaic panel member 121 to move along the guiding direction. The guide rail assembly 130 is adapted to be connected to the chassis 106. In a state where the guide rail assembly 130 is assembled to the container 100, the guiding direction is kept consistent with the width direction D2 of the container 100. The retracting and deploying drive assembly 140 includes a chain drive member 141 and a drive member 151. The chain drive member 141 is arranged side by side with the guide rail assembly 130. The chain drive member 141 includes a chain 142 adapted to engage with the traveling sprocket 129. The drive member 151 is drivingly connected to the chain drive member 141, and the drive member 151 is used to drive the chain 142 to move so as to drive the photovoltaic panel member 121 to move along the guiding direction. That is, during the movement of the chain 142, the chain 142 can drive the lower part of the photovoltaic panel member 121 to move, thereby pulling the photovoltaic panel member 121 to move outside or inside the container 100. The drive member 151 is adapted to be disposed inside the photovoltaic container. The chain drive member 141 is adapted to be detachably disposed outside the photovoltaic container.

[0092] The automatic retractable photovoltaic device according to the embodiments of the present application can guide the photovoltaic panel assembly 120 during the unfolding and folding processes by setting the guide rail assembly 130 to cooperate with the guide wheel members of the photovoltaic panel assembly 120. By setting the retracting and deploying drive assembly 140, the driving member 151 can be used to provide power to drive the chain drive member 141 to operate, and the cooperation between the chain 142 of the chain drive member 141 and the running sprocket 129 of the photovoltaic panel assembly 120 is used to drive the photovoltaic panel assembly 120 to move, thereby helping to realize the automatic unfolding and folding of the photovoltaic panel assembly 120. Moreover, in the state of being applied to a photovoltaic container, since the chain drive member 141 can be detachably connected to the photovoltaic container, it is convenient to disassemble the chain drive member 141 and put it into the photovoltaic container or other containers for transportation, and it is also convenient to save the number of operators when the chain drive member 141 is assembled to the photovoltaic container of the integrated energy storage and microgrid container. In the state where the guide rail assembly 130 and the chain drive member 141 are installed on the integrated energy storage and microgrid container, by starting the driving member 151, the automatic unfolding and folding of the photovoltaic panel assembly 120 can be realized, which is beneficial to saving manpower and can reduce or eliminate the use of auxiliary machinery. In the state of being applied to a photovoltaic container, in terms of on-site deployment, it is beneficial to reduce the complexity of installation and disassembly operations, beneficial to reducing the requirements for the professionalism and the number of operators, and also beneficial to reducing the dependence on large auxiliary mechanical equipment and improving the scene adaptability.

[0093] Refer to Figure 4 、 Figure 6 、 Figure 9 and Figure 10 , when the chain drive member 141 is connected to the container 100, the chain drive member 141 is located outside the container 100 and extends along the width direction D2 of the container 100 and is arranged outside the underframe 106. The photovoltaic panel member 121 moves away from the container 100 to realize the unfolding of the photovoltaic panel assembly 120, thereby switching the photovoltaic panel assembly 120 to the use state. The photovoltaic panel member 121 moves closer to the container 100 to realize the folding of the photovoltaic panel assembly 120, thereby switching the photovoltaic panel assembly 120 to the storage state.

[0094] Optionally, the chain drive member 141 is detachably connected to the bottom side beam 106c of the underframe 106.

[0095] Refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5, Exemplarily, among any three adjacent photovoltaic panel members 121, the upper part of the middle photovoltaic panel member 121 is hinged to the upper part of one of the remaining two photovoltaic panel members 121, and the lower part of the middle photovoltaic panel member 121 is hinged to the lower part of the other of the remaining two photovoltaic panel members 121. Two adjacent photovoltaic panel members 121 have a deployed state and a folded state. The distance between the traveling sprockets 129 of two adjacent photovoltaic panel members 121 in the deployed state along the guiding direction is less than or equal to the dimension of the chain transmission member 141 along the guiding direction. Two adjacent photovoltaic panel members 121 in the folded state are stacked relative to each other. When any two adjacent photovoltaic panel members 121 are both in the deployed state, the photovoltaic panel assembly 120 is in the use state. When any two adjacent photovoltaic panel members 121 are both in the folded state, the photovoltaic panel assembly 120 is in the storage state.

[0096] Refer to Figure 4 and Figure 5 , Further, the photovoltaic panel assembly 120 further includes a plurality of deployment limiting members 126. Both ends of the deployment limiting member 126 are hinged between adjacent photovoltaic panel members 121. The deployment limiting member 126 is used to limit the maximum included angle between adjacent photovoltaic panel members 121. The deployment limiting member 126 is in a foldable structural form. The deployment limiting member 126 includes a first limiting rod 127 and a second limiting rod 128 that are hinged to each other. The ends of the first limiting rod 127 and the second limiting rod 128 close to each other have a stop structure that can limit rotation relative to each other. When the included angle between adjacent photovoltaic panel members 121 is deployed to the maximum included angle, the stop structure of the first limiting rod 127 abuts against the stop structure of the second limiting rod 128 to prevent the first limiting rod 127 from pivoting relative to the second limiting rod 128. To prevent jamming of two adjacent photovoltaic panel members 121 during folding and resulting in inability to fold, when the stop structure of the first limiting rod 127 abuts against the stop structure of the second limiting rod 128, the included angle between the first limiting rod 127 and the second limiting rod 128 is less than 180°. This ensures that after the photovoltaic panel assembly 120 is deployed, among the included angles between all adjacent photovoltaic panel members 121, the sizes of the included angles with the opening facing down are as consistent as possible.

[0097] Specifically, the deployment limiting member 126 is located between adjacent photovoltaic panel members 121 that are hinged to each other at the upper part.

[0098] Refer to Figure 1 , Figure 3 , Figure 12 and Figure 16, Exemplarily, the guide rail assembly 130 includes a first guide rail member 134 and a second guide rail member 135. The first guide rail member 134 is adapted to be disposed along the guiding direction on the upper part of the chassis 106. The second guide rail member 135 is adapted to be detachably connected to the chassis 106 and arranged in continuation with the first guide rail member 134 along the guiding direction. And in the guiding direction, the length of the second guide rail member 135 is greater than the length of the first guide rail member 134, and the length of the second guide rail member 135 is greater than the dimension of the chain drive member 141 along the guiding direction. The first guide rail member 134 is used to support the photovoltaic panel assembly 120 and allow the photovoltaic panel assembly 120 to be moved out of and into the photovoltaic cabin 101. The second guide rail member 135 is used to allow the photovoltaic panel assembly 120 to move outside the container 100, so as to realize unfolding and folding.

[0099] Refer to Figure 1 , Figure 3 , Figure 4 , and Figures 12 to 16 , Further, the first guide rail member 134 includes a guide rail part 131. The second guide rail member 135 includes a plurality of guide rail parts 131, a plurality of guide rail brackets 132, and a plurality of guide rail seats 133. The plurality of guide rail parts 131 are adapted to be arranged along the guiding direction. The guide rail part 131 is adapted to be detachably connected to the upper part of the guide rail bracket 132. The guide rail bracket 132 is adapted to be disposed at least at both ends of the guide rail part 131. The adjacent ends of two adjacent guide rail parts 131 close to each other are adapted to be connected to the same guide rail bracket 132. The lower part of the guide rail bracket 132 is adapted to be detachably connected to the guide rail seat 133. The guide rail seat 133 includes a connecting part 133a and / or a mounting hole 133b. The connecting part 133a is located at the end of the guide rail seat 133 to be adapted to connect two adjacent guide rail seats 133 through an external connecting member. The mounting hole 133b is adapted to be fastened to the ground at the target use location through a fastener. The connecting part 133a is applicable to the scenario where the wind force in the use environment is weak and there is no need to fix the guide rail seat 133 to the ground. The mounting hole 133b is adapted to be fastened to the ground at the target use location through a fastener to adapt to the scenario where the wind force in the use environment is strong and reinforcement is required.

[0100] Optionally, the connecting part 133a is configured as a hole for threading flexible connecting members such as cable ties. The mounting hole 133b is adapted to connect bolts.

[0101] Refer to Figure 2 and Figure 12Optionally, the PV cabin 101 is adapted to accommodate disassembled rail members 131, rail brackets 132, and rail mounts 133. To this end, a pair of first rail members 134 are typically provided on the upper portion of the chassis 106 of the PV cabin 101. The space between the pair of first rail members 134, as well as the space on either side of the pair of first rail members 134, is adapted to accommodate disassembled rail members 131, rail brackets 132, and rail mounts 133, as well as the chain drive member 141 removed from the exterior of the container 100.

[0102] See Figure 3 and Figure 8 Furthermore, the guide rail member 131 includes an upper wing plate 131a, a support plate 131b and a lower wing plate 131c. The upper wing plate 131a is connected to the upper part of the support plate 131b. The upper wing plate 131a protrudes from both sides of the support plate 131b along the thickness direction of the support plate 131b. In the assembled state where the guide rail assembly 130 is assembled to the container 100, the thickness direction of the support plate 131b is parallel to or substantially parallel to the length direction D1 of the container 100. The lower wing plate 131c is connected to the lower part of the support plate 131b. The lower wing plate 131c is suitable for being connected to the guide rail bracket 132 by means of bolt connection or the like. Overall, the cross-sectional shape of the guide rail member 131 is an "I" shape or close to an "I" shape. The guide wheel component includes a main roller 123, a secondary wheel connecting member 124 and a secondary roller 125. The main roller 123 and the secondary wheel connector 124 are both rotatably connected to the lower portion of the photovoltaic component 121 around the axis of the main roller 123. The main roller 123 is suitable for contacting the upper portion of the upper wing plate 131a. Secondary wheel connectors 124 are respectively provided at both ends of the main roller 123 in the axial direction. Each secondary wheel connector 124 is provided with a secondary roller 125. The secondary roller 125 is rotatably connected to the secondary wheel connector 124 around the axis of the secondary roller 125. The axis of the secondary roller 125 is parallel to the axis of the main roller 123. The secondary roller 125 is suitable for contacting the lower portion of the upper wing plate 131a. By limiting the upper wing plate 131a in the vertical direction D3 by the main roller 123 and the secondary roller 125, the photovoltaic panel assembly 120 can be prevented from separating from the guide rail assembly 130 in the vertical direction D3. The secondary wheel connectors 124 on both sides of the main roller 123 can limit the horizontal displacement of the photovoltaic panel assembly 120, thereby improving the wind resistance of the photovoltaic panel assembly 120.

[0103] See Figure 5 Optionally, photovoltaic panel assembly 120 is provided with fixing rings 111 on both sides perpendicular to the expansion and contraction direction, suitable for connecting to a fixed object via cables. Depending on the wind level, users can add cables and ground stakes, tied to fixing rings 111, to further enhance the wind resistance of photovoltaic panel assembly 120.

[0104] Further, limiting portions extending downward to the lower wing plate 131c are formed on both side edges of the upper wing plate 131a. The limiting portions are spaced apart from the lower wing plate 131c. The auxiliary rollers 125 are adapted to be arranged between the support plate 131b and the limiting portions. This can further limit the horizontal displacement of the photovoltaic panel assembly 120 and contribute to enhancing the wind resistance and anti-roll performance of the photovoltaic panel assembly 120.

[0105] Optionally, in the case where the upper wing plate 131a is a sheet metal part, the limiting portion can be understood as a flange of the upper wing plate 131a.

[0106] Optionally, each auxiliary wheel connecting member 124 is respectively provided with at least two auxiliary rollers 125. The axes of the respective auxiliary rollers 125 are coplanar. The multiple auxiliary rollers 125 can increase the load-bearing effect, thereby meeting the wind resistance requirements under higher wind force levels.

[0107] In Figure 3 and Figure 8 In the example shown, each auxiliary wheel connecting member 124 connects two auxiliary rollers 125. The main roller 123 rests on the track. The auxiliary wheel connecting members 124 on both sides of the main roller 123 are close to both sides of the track and leave a small gap. The auxiliary rollers 125 are installed inside the auxiliary wheel connecting members 124. This ensures that the roller mechanism is relatively locked with the track, preventing the rollers from deviating out of the track due to external forces. In this way, the photovoltaic panel assembly 120 can be locked with the guide rail assembly 130 after being unfolded and has a certain wind resistance performance.

[0108] Referring to Figure 17 , optionally, the support plate 131b and the lower wing plate 131c are integrally formed. The upper wing plate 131a is welded to the upper part of the support plate 131b. This not only facilitates the separate manufacture of different parts of the guide rail member 131 but also helps to improve the manufacturing accuracy and flexibility.

[0109] Optionally, a limiting boss is formed on the part of the upper wing plate 131a corresponding to the support plate 131b and facing away from the lower wing plate 131c. The main roller 123 has a limiting groove for receiving the limiting boss. This helps to limit the main roller 123 and the guide rail member 131 axially with respect to each other, thereby preventing the main roller 123 from deviating from the guide rail member 131. The contact area of the limiting boss with the upper wing plate 131a at the limiting groove is smaller than the surface area of the top surface of the limiting boss. This is beneficial for reducing the contact area between the main roller 123 and the guide rail member 131 and can reduce the friction force when sliding on the guide rail member 131.

[0110] Referring to Figure 9, optionally, the number of the guide rail assemblies 130 is two groups. The two groups of guide rail assemblies 130 are respectively arranged corresponding to the two ends of the photovoltaic panel member 121 in the horizontal direction. The photovoltaic panel member 121 includes two groups of main rollers 123, two groups of auxiliary wheel connectors 124, and two groups of auxiliary rollers 125. The two groups of main rollers 123, the two groups of auxiliary wheel connectors 124, and the two groups of auxiliary rollers 125 are respectively arranged corresponding to the two groups of guide rail assemblies 130.

[0111] Specifically, the top end of the first photovoltaic panel member 121 inside the box is hinged to the top end of the second photovoltaic panel member 121 to form a rotatable structure. The bottom end of the second photovoltaic panel member 121 is hinged to the bottom end of the third photovoltaic panel member 121 to form a rotatable structure. Such multi-piece cascading is repeated and extended out of the box to form the photovoltaic panel assembly 120. In the direction from inside the box to outside the box, two guide wheel members are assembled at the bottom ends of all the photovoltaic panel members 121 with odd orders. A toothed plate is assembled on one side of each pulley. The guide wheel member includes the above-mentioned main roller 123, auxiliary wheel connector 124, and auxiliary roller 125. The toothed plate is the traveling sprocket 129. A guide rail member 131 is fixedly provided in the photovoltaic cabin 101 for the photovoltaic panel member 121 to move from inside the box to outside the box. Two groups of extended guide rail assemblies 130 are arranged on the ground of the photovoltaic storage cabin. The photovoltaic panel assembly 120 is seated on the guide rail assemblies 130 through the guide wheel members and can slide along the extending direction of the guide rail assemblies 130.

[0112] Optionally, the photovoltaic panel member 121 includes a photovoltaic frame and a photovoltaic panel piece 122 connected to the frame. Adjacent photovoltaic panel members 121 are hinged through their respective photovoltaic frames. Each photovoltaic frame can be installed with a corresponding number of photovoltaic panel pieces 122 as required. Here, the corresponding number can be 1, 2, 3, or more than 3, etc. In the case where each photovoltaic frame has two or more photovoltaic panel pieces 122, the arrangement directions of the respective photovoltaic panel pieces 122 can be arranged in the horizontal direction, or in the height direction, or in two or more directions such as the horizontal direction and the height direction respectively. Among them, the photovoltaic frame can be square or other shapes. In this embodiment, the outer shape of the photovoltaic frame is rectangular. And in the state of being installed on the container 100, the length direction of the photovoltaic frame is consistent with the length direction D1 of the container 100.

[0113] Refer to Figure 1 and Figure 4, in a state where the guide rail assembly 130 and the chain drive member 141 are assembled to the container 100, the length of the guide rail assembly 130 in the width direction D2 of the container 100 is not less than the length of the chain drive member 141 in the width direction D2 of the container 100. On the one hand, this can make full use of the guiding function of the guide rail assembly 130 to fully deploy the photovoltaic panel assembly 120. On the other hand, it also helps the chain drive member 141 to be stored in the photovoltaic cabin 101 after being disassembled from the container 100.

[0114] Refer to again Figure 1 and Figure 4 , optionally, in the width direction D2 of the container 100, the length of the portion of the guide rail assembly 130 located outside the container 100 is greater than the length of the portion of the chain drive member 141 located outside the container 100 in the width direction D2. When the included angle between two adjacent upper photovoltaic panel members 121 hinged to each other reaches the maximum included angle, the distance between the lower portions of these two photovoltaic panel members 121 is less than or equal to the length of the portion of the chain drive member 141 located outside the container 100 in the width direction D2. When switching the photovoltaic panel assembly 120 from the use state to the storage state, as long as the running sprockets 129 at two photovoltaic panel members 121 are engaged with the chain 142, the movement of the chain 142 can be used to drive the photovoltaic panel members 121 to move into the box.

[0115] Of course, in some examples, when the included angle between two adjacent upper photovoltaic panel members 121 hinged to each other reaches the maximum included angle, the distance between the lower portions of these two photovoltaic panel members 121 is greater than the length of the portion of the chain drive member 141 located outside the container 100 in the width direction D2. When switching the photovoltaic panel assembly 120 from the use state to the storage state, as long as the running sprocket 129 at one photovoltaic panel member 121 is engaged with the chain 142, the movement of the chain 142 can be used to drive the photovoltaic panel member 121 to move into the box.

[0116] Refer to Figure 12 , Figure 14 and Figure 16 , exemplarily, the automatic retractable photovoltaic device includes at least two first telescopic limit members 136. The at least two first telescopic limit members 136 are adapted to be arranged between two groups of guide rail assemblies 130 and spaced apart along the guiding direction. One end of the first telescopic limit member 136 is adapted to be detachably connected to the second guide rail member 135 of a group of guide rail assemblies 130 by means of bolt connection or the like. The other end of the first telescopic limit member 136 is adapted to be detachably connected to the second guide rail member 135 of another group of guide rail assemblies 130 by means of bolt connection or the like. The first telescopic limit member 136 is configured to be able to linearly expand and contract and at least lock the length in the extended state.

[0117] Continue to refer to Figure 12 ,Figure 14 and Figure 16 , further, in the guide rail bracket 132 of the second guide rail member 135, a part of the guide rail bracket 132 is provided with a connecting ear. A guide rail bracket 132 with a connecting ear is provided below each guide rail member 131. The first telescopic limiting member 136 is connected to the connecting ear by a bolt. The first telescopic limiting member 136 includes two first end rods, a first middle sleeve and a first locking member. The two first end rods are connected inside the first middle sleeve and can perform telescopic movement between a position extending out of the first middle sleeve and a position retracting into the first middle sleeve. The first end rod and the first middle sleeve are respectively provided with positioning holes, and the positioning holes of the two are aligned when the first telescopic limiting member 136 is in the extended state. The first locking member is detachably connected to the first end rod and the first middle sleeve at the positioning holes, so that the first telescopic limiting member 136 can be kept in the extended state, thereby keeping the distance between the two groups of connected guide rail assemblies 130. After the two first end rods retract into the first middle sleeve, the total length of the first telescopic limiting member 136 is reduced, which is beneficial to accommodating the first telescopic limiting member 136 in the space below the photovoltaic panel assembly 120 in the photovoltaic cabin 101.

[0118] A method for assembling the guide rail assembly 130 will be described below, and some specific structures of the guide rail assembly 130 will be further elaborated.

[0119] After the underframe 106 of the container 100 is positioned on the ground, the parts of the second guide rail member 135 below the photovoltaic panel assembly 120 are taken out. First, the guide rail seats 133 are spliced end to end in the direction of the inner container track, and then the guide rail brackets 132 are placed in sequence according to the bolt holes on the guide rail seats 133, and a guide rail bracket 132 with a U-shaped support is arranged below each guide rail member 131. Align the segmented guide rail members 131 with the two guide rail members 131 welded on the underframe 106, and place the guide rail members 131 on the guide rail brackets 132 in sequence. The end of the first guide rail member 131 and the head of the last guide rail member 131 overlap on the same guide rail bracket 132, and the guide rail member 131 is fixed to the guide rail bracket 132 with bolts. The first telescopic limit member 136 includes two square tubes of the same length and one sleeve. Through holes are provided at both ends of the square tubes and are symmetrically distributed, which ensures correct installation without the need to identify the direction. Insert the square tubes into both sides of the sleeve respectively, and insert the limit pins after aligning the reserved holes of the square tube and the sleeve, then a set of the first telescopic limit member 136 is assembled. Place both ends of the first telescopic limit member 136 on the U-shaped supports of the guide rail brackets 132 with U-shaped supports respectively, and insert the limit pins after aligning the reserved holes on the first telescopic limit member 136 and the U-shaped supports, so as to ensure that the relative distance between the two guide rail assemblies 130 meets the installation requirements, thus eliminating the need for measuring tools such as a tape measure to assist in positioning. The guide rail seat 133 is provided with a concave part, a convex part and a transition part located between the two. The concave part is lower than the convex part. The concave part is connected to the convex part through the transition part. In the state where the guide rail seat 133 is placed on the ground, the concave part contacts the ground, and a certain distance is formed between the convex part and the ground. The connecting part of the guide rail bracket 132 and the guide rail seat 133 is located on the convex part. Thus, when the guide rail bracket 132 is fixed to the guide rail seat 133 with bolts, it is beneficial to prevent the bolts from exceeding the lower surface of the guide rail seat 133 and touching the ground, ensuring the stability of the guide rail seat 133. In Figure 15In the example shown, the guide rail base 133 includes three protruding portions and two recessed portions. The three protruding portions are arranged at intervals along the width direction of the guide rail base 133, and the recessed portions are provided between adjacent protruding portions. The protruding portion in the middle is more conducive to ensuring the flatness of the two recessed portions on both sides during processing. Thus, the guide rail base 133 forms multiple bending structures, which is beneficial to increasing the overall rigidity of the guide rail base 133. The protruding portions at both ends are used to connect the guide rail brackets 132. Holes are prefabricated at the protruding positions at the head and tail of the guide rail base 133 as connection parts 133a. Cable ties can be passed through the holes to tie the head and tail ends of the guide rail base 133 together, so as to facilitate the assembly of the second guide rail member 135. The recessed portions of the guide rail base 133 are used to set the mounting holes 133b, so that when connecting to the ground, foundation, etc. using fasteners, the guide rail base 133 can be reliably contacted with the ground, foundation, etc. The guide rail bracket 132 has an inverted U-shaped structure, and the guide rail bracket 132 has two opposite legs. The lower ends of the legs are connected to the protruding portions on both sides of the guide rail base 133. Among them, the lower ends of the two legs of the guide rail bracket 132 are provided with bent feet. Holes are opened in the feet. Correspondingly, another hole is opened in the protruding portion of the guide rail base 133. The guide rail bracket 132 is connected to the guide rail base 133 by passing fasteners such as bolts and nuts through the holes in the feet and the holes in the guide rail base 133. For the guide rail bracket 132, the bending of the feet can be bent towards the direction close to the other leg (as shown in Figure 3 shown), or can be bent towards the direction away from the other leg (as shown in Figure 15 shown). Comparatively speaking, by bending the feet towards the direction away from the other leg, it is beneficial to increase the space for installation operation, thereby improving the flexibility and convenience of assembly, and further contributing to improving the assembly efficiency.

[0120] Referring to Figure 6 , Figure 7 , Figure 9 , 10 , Figure 13 , Figure 19 and Figure 20 , exemplarily, the chain drive member 141 further includes a chain drive frame 156, a driving sprocket 157 and a driven sprocket. The chain drive frame 156 is adapted to be detachably connected to the chassis 106. The driving sprocket 157 is rotatably connected to one end of the chain drive frame 156. The driven sprocket is rotatably connected to the other end of the chain drive frame 156. The driving sprocket 157 and the driven sprocket are arranged at intervals. The chain 142 is wound around the driving sprocket 157 and the driven sprocket. In other words, the driving sprocket 157, the driven sprocket and the chain 142 are connected as a whole through the chain drive frame 156, so that the chain drive member 141 can be integrally assembled to the chassis 106 and integrally removed from the chassis 106.

[0121] Referring to Figure 17 , Figure 19 andFigure 20 , optionally, a flange plate 156e is provided at one end of the sprocket transmission frame, and the flange plate 156e can be bolted to the sealing plate 106d at the chassis 106. After bolting, the chain transmission member 141 is aligned with the traveling sprocket 129 at the bottom of the photovoltaic panel assembly 120.

[0122] Refer to Figure 6 , Figure 7 , Figure 19 and Figure 20 , further, the chain transmission frame 156 includes a frame body 156a and a pair of guiding members 155. The frame body 156a is provided with a driving sprocket 157, a driven sprocket and a chain 142. The driving sprocket 157, the driven sprocket and the chain 142 partially protrude above the frame body 156a. One end of the frame body 156a provided with the driving sprocket 157 is adapted to be detachably connected to the side of the chassis 106 by means of bolt connection or the like. A pair of guiding members 155 protrude from both ends of the frame body 156a. At least part of the guiding members 155 protrude above the frame body 156a. One of the pair of guiding members 155 is adapted to be detachably connected to the upper part of the chassis 106. The guiding member 155 includes a guiding groove 155d. The guiding groove 155d is aligned with the chain 142 along the guiding direction. And the opening width of the guiding groove 155d decreases from both ends to the middle. The guiding groove 155d is adapted for the traveling sprocket 129 to pass through. In other words, the guiding groove 155d is in the shape of a flared opening that gradually tapers from both ends to the middle along the guiding direction. By providing the guiding members 155, it is beneficial to position the photovoltaic panel member 121 in the horizontal position perpendicular to the guiding direction, so that the traveling sprocket 129 below the photovoltaic panel member 121 can be more accurately docked with the chain 142.

[0123] Refer to Figure 19 , optionally, the guiding member 155 includes a guiding connection portion 155b and a guiding lining portion 155c. The guiding connection portion 155b is located outside the guiding lining portion 155c. The guiding connection portion 155b is connected to the frame body 156a. The guiding lining portion 155c defines the guiding groove 155d. The guiding connection portion 155b is provided as a metal part. By providing the guiding lining portion 155c inside the guiding connection portion 155b, it is beneficial to prevent the traveling sprocket 129 from directly contacting the guiding connection portion 155b and causing friction. The guiding lining portion 155c is provided as a wear-resistant non-metal part. For example, the guiding lining portion 155c is a nylon block made of nylon material. Overall, the two ends of the nylon block are in a flared shape, which is convenient for the traveling sprocket 129 of the photovoltaic panel assembly 120 to fall into or withdraw from the chain transmission member 141. The guiding member 155 is provided with a receiving notch 155a adapted to receive the bottom side beam 106c of the chassis 106.

[0124] Refer to Figure 12 , Figure 13 ,Figure 16 and Figures 18 to 20 , further, support seats 156b are provided at both ends of the frame body 156a. Lugs 156a1 are provided on both sides of the frame body 156a along the axial direction of the driving sprocket 157. The lugs 156a1 are located between the support seats 156b at both ends. The chain transmission member 141 further includes a support positioning seat 156c. A pair of first support arms 156c1 are provided on the upper part of the support positioning seat 156c. The pair of first support arms 156c1 are arranged at intervals along the axial direction of the driving sprocket 157. A first limiting groove 156c2 adapted to receive the frame body 156a is defined between the pair of first support arms 156c1. A pair of second support arms 156c3 are provided on the upper part of the first support arm 156c1. The pair of second support arms 156c3 are arranged at intervals in the guiding direction. A second limiting groove 156c4 adapted to receive the lug 156a1 is defined between the pair of second support arms 156c3. The support positioning seat 156c and the support seat 156b jointly support the chain transmission member 141. By providing the lugs 156a1 on the frame body 156a, the positioning and assembly are realized by the cooperation of the support positioning seat 156c and the lugs 156a1, so as to facilitate the installation of the support positioning seat 156c on the frame body 156a. Compared with the case where the support positioning seat 156c is not provided, the embodiment of the present application can enhance the load-bearing performance of the frame body 156a. The support positioning seat 156c and the frame body 156a are limited to each other in the guiding direction and the axial direction of the driving sprocket 157.

[0125] Refer to Figure 12 and Figure 16 , refer to the figure. Further, the automatic retractable photovoltaic device includes two groups of chain transmission members 141, two groups of support positioning seats 156c and at least two second telescopic limiting members 156d. The two groups of chain transmission members 141 are arranged at intervals along the axial direction of the driving sprocket 157. The two groups of support positioning seats 156c are respectively arranged corresponding to the two groups of chain transmission members 141. The number of each group of support positioning seats 156c is the same as the number of the second telescopic limiting members 156d. One end of the second telescopic limiting member 156d is adapted to be detachably connected to one support positioning seat 156c in a group of support positioning seats 156c by means of bolt connection or the like. The other end of the second telescopic limiting member 156d is adapted to be detachably connected to one support positioning seat 156c in the other group of support positioning seats 156c by means of bolt connection or the like. The second telescopic limiting member 156d is configured to be a structure that can linearly expand and contract and can lock the length at least in the extended state. In the assembled state where the two groups of chain transmission members 141 are connected to the chassis 106, the distance between the ends of the two groups of chain transmission members 141 connected to the chassis 106 is determined. On this basis, when the second telescopic limiting member 156d is locked in the extended state and connected to the opposite two second telescopic limiting members 156d, it helps to maintain the distance between the two groups of chain transmission members 141.

[0126] Optionally, the number of the second telescopic limit members 156d is at least two. At least two second telescopic limit members 156d are adapted to be arranged between two sets of chain transmission members 141 and spaced apart along the guiding direction.

[0127] In Figure 12 and Figure 16 In the illustrated example, the number of the second telescopic limit members 156d is two.

[0128] Optionally, the second telescopic limit member 156d includes two second end rods, a second middle sleeve, and a second locking member. The two second end rods are connected inside the second middle sleeve and can perform telescopic movement between a position extending out of the second middle sleeve and a position retracting into the second middle sleeve. The second end rod and the second middle sleeve are each provided with a positioning hole, and the positioning holes of the two are aligned when the second telescopic limit member 156d is in the extended state. The second locking member is detachably connected to the second end rod and the second middle sleeve at the positioning hole, so that the second telescopic limit member 156d can be kept in the extended state, thereby keeping the distance between a pair of supported positioning seats 156c connected thereto, and further keeping the distance between the two sets of chain transmission members 141. After the two second end rods retract into the second middle sleeve, the total length of the second telescopic limit member 156d is reduced, which is beneficial to storing the second telescopic limit member 156d in the space under the photovoltaic panel assembly 120 in the photovoltaic cabin 101.

[0129] Referring to Figure 19 and Figure 20 , further, the axis of the driving sprocket 157 and the axis of the driven sprocket define a first plane. The chain 142 includes an upper chain portion located above the first plane and a lower chain portion located below the first plane. The chain transmission member 141 further includes a supporting member 154 and a tensioning sprocket 159. The supporting member 154 is located below the upper chain portion. The supporting member 154 is fixed to the frame body 156a. The supporting member 154 is adapted to support the upper chain portion to prevent the deflected upper chain portion from contacting the frame body 156a. The tensioning sprocket 159 is located on the lower side of the lower chain portion and meshes with the lower chain portion to be adapted to tension the chain 142. It can be understood that the upper chain portion and the lower chain portion are two parts of the chain 142 located on the upper and lower sides of the first plane at any moment. By providing the supporting member 154, it is beneficial to prevent the upper chain portion from rubbing against the frame body 156a due to deflection and extend the service life of the chain transmission member 141.

[0130] Optionally, the supporting member 154 is a resin plate.

[0131] Referring to Figure 12 , Figure 13 , Figure 16 , Figure 19 and Figure 20, Further, the chain drive member 141 further includes a plurality of limiters 158. The plurality of limiters 158 are arranged at intervals along the traveling direction of the chain 142. The limiter 158 is used to support the lower chain portion and limit the lower chain portion axially of the driving sprocket 157. The limiter 158 has a resin plate. The resin plate is used to directly contact the chain 142, thereby preventing the chain 142 from directly rubbing against the frame body 156a.

[0132] Refer to Figure 4 , Figures 10 to 12 and Figure 16 , In addition, the retracting and extending drive assembly 140 further includes an intermediate drive member 144. At least a part of the intermediate drive member 144 is adapted to be disposed in the clamping cavity 106b of the chassis 106. The clamping cavity 106b of the chassis 106 is located below the floor 106a. During the assembly process, the installation of the floor 106a can be carried out after the assembly of the intermediate drive member 144 is completed. The drive member 151 is located inside the container 100. One end of the intermediate drive member 144 is connected to the drive member 151. The other end of the intermediate drive member 144 is detachably connected to the driving sprocket 157, so as to be adapted to transmit the power of the drive member 151 to the driving sprocket 157. When the drive member 151 outputs power, the driving sprocket 157 can be driven to rotate, thereby driving the chain 142 to move cyclically, so as to drive each photovoltaic panel member 121 to move. It should be noted that one end of the intermediate drive member 144 is the power input end of the intermediate drive member 144, and the other end of the intermediate drive member 144 is the power output end of the intermediate drive member 144.

[0133] Continue to refer to Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 12 and Figure 16, Further, the driving member 151 is an electric motor. The electric motor is adapted to be arranged on the upper part of the chassis 106 at the energy storage compartment 102. The intermediate transmission member 144 includes a first transmission shaft 145, a second transmission shaft 146, a first bevel gear 147, a second bevel gear 148, a third bevel gear 149, and a fourth bevel gear 143. The first transmission shaft 145 extends along the length direction D1 of the container 100. The first transmission shaft 145 is connected to the output shaft of the electric motor. The second transmission shaft 146 extends in a direction perpendicular to the first transmission shaft 145. The first bevel gear 147 is fixed to the first transmission shaft 145. Both the second bevel gear 148 and the third bevel gear 149 are fixed to the second transmission shaft 146. The second bevel gear 148 meshes with the first bevel gear 147. The fourth bevel gear 143 is directly or indirectly drivingly connected to the driving sprocket 157. In the present application, the fourth bevel gear 143 and the driving sprocket 157 are coaxial and fixedly connected to each other. In a state where the chain transmission member 141 is connected to the container 100, the fourth bevel gear 143 meshes with the third bevel gear 149. Here, the power transmission between the first transmission shaft 145 and the second transmission shaft 146 is achieved through the cooperation of the first bevel gear 147 and the second bevel gear 148. The power transmission between the second transmission shaft 146 and the driving sprocket 157 is achieved through the cooperation of the third bevel gear 149 and the fourth bevel gear 143, and finally the power is transmitted to the chain 142 to move the chain 142. It should be noted that the fourth bevel gear 143 is indirectly drivingly connected to the driving sprocket 157, which can be understood as that the fourth bevel gear 143 is connected to the driving sprocket 157 through an intermediate transmission structure. Among them, the intermediate transmission structure can be a transmission form such as gear transmission. The fourth bevel gear 143 is the other end of the intermediate transmission member 144, that is, the power output end of the intermediate transmission member 144.

[0134] In the illustrated example, the number of the chain transmission members 141 is two groups. In the application state of the automatic retractable and extendable photovoltaic device, the two groups of chain transmission members 141 are arranged at intervals along the axial direction of the first transmission shaft 145, and both the two groups of chain transmission members 141 extend in a direction perpendicular to the first transmission shaft 145. The intermediate transmission member 144 includes one first transmission shaft 145, two groups of second transmission shafts 146, two groups of first bevel gears 147, two groups of second bevel gears 148, two groups of third bevel gears 149, and two groups of fourth bevel gears 143. The two groups of second transmission shafts 146 are parallel to each other and arranged at intervals along the axial direction of the first transmission shaft 145. The two groups of first bevel gears 147 are arranged at intervals along the axial direction of the first transmission shaft 145. The two groups of second bevel gears 148 are respectively arranged at one end of the two groups of second transmission shafts 146 close to the first transmission shaft 145. The two groups of third bevel gears 149 are respectively arranged at one end of the two groups of second transmission shafts 146 away from the first transmission shaft 145. The two groups of fourth bevel gears 143 are respectively arranged on the two groups of chain transmission members 141.

[0135] In other examples, the number of chain drive members 141 may be three or more. Correspondingly, the number of each of the second transmission shaft 146, the first bevel gear 147, the second bevel gear 148, the third bevel gear 149, and the fourth bevel gear 143 matches the number of chain drive members 141.

[0136] Refer to Figure 17 , further, the second transmission shaft 146 includes a first shaft section 146a and a second shaft section 146b. The second shaft section 146b is detachably connected to the first shaft section 146a. At least a part of the first shaft section 146a is adapted to be arranged in the clamping cavity 106b. At least a part of the second shaft section 146b is adapted to be arranged outside the chassis 106. The first bevel gear 147 is fixed to the first transmission shaft 145. The second bevel gear 148 is fixed to the first shaft section 146a. The second bevel gear 148 meshes with the first bevel gear 147. The third bevel gear 149 is fixed to the second shaft section 146b. The first shaft section 146a and the second shaft section 146b are detachably connected by a key connection method such as a spline or a flat key. In a state where the first shaft section 146a is assembled to the chassis 106, the end of the first shaft section 146a is exposed on the side of the bottom side beam 106c, or the end of the first shaft section 146a is located at a position where it can be conveniently docked with the second shaft section 146b. The second shaft section 146b and the third bevel gear 149 are formed as an integral part, or the second shaft section 146b and the third bevel gear 149 are detachably connected.

[0137] Optionally, to prevent the first shaft section 146a and the second shaft section 146b from axially separating from each other along the second transmission shaft 146, the first shaft section 146a and the second shaft section 146b are locked and connected by a locking screw. Specifically, a spline hole and a locking hole are provided at the end of the first shaft section 146a. The locking hole penetrates from the outer surface of the first shaft section 146a to the spline hole in the radial direction of the first shaft section 146a. The locking hole is a threaded hole. A spline portion is provided at the end of the second shaft section 146b, and the spline portion is adapted to be inserted into the spline hole. The spline portion is provided with a locking groove or another locking hole corresponding to the locking hole. After the second shaft section 146b is inserted into the first shaft section 146a, the locking screw is inserted into the locking hole and tightened until the locking screw enters the locking groove or another locking hole.

[0138] Refer to Figure 17, correspondingly, to facilitate the docking of the first shaft section 146a and the second shaft section 146b and support the assembled second transmission shaft 146, the bottom side beam 106c of the chassis 106 in the embodiment of the present application has a groove with an opening facing outward in the width direction D2 of the container 100. The groove of the bottom side beam 106c is used to fixedly install a bearing seat, and the bearing seat will not exceed the side surface of the bottom side beam 106c, which is beneficial to improving the space utilization rate of the bottom side beam 106c. In this regard, the bottom side beam 106c includes a channel steel or an H-shaped steel. Compared with using a square tube, using a channel steel or an H-shaped steel and other section steels with a groove structure is more beneficial to meeting the requirements of the groove structure on the premise of having structural strength, and is also convenient for anti-corrosion treatment and the like.

[0139] To achieve a reliable connection between the chain drive member 141 and the bottom side beam 106c, the bottom side beam 106c further includes a sealing plate 106d with flange holes. The sealing plate 106d is welded to the notch of section steels such as channel steel or H-shaped steel to block part of the notch. The sealing plate 106d is used to be assembled with the chain drive frame 156 by means of bolt connection, riveting, etc.

[0140] Refer to Figure 10 , exemplarily, the output shaft of the motor is connected to the first cylindrical gear 152. The second cylindrical gear 153 is fixed on the first transmission shaft 145. The first cylindrical gear 152 meshes with the second cylindrical gear 153. At least one of the transmission ratios of the first cylindrical gear 152 to the second cylindrical gear 153, the transmission ratio of the first bevel gear 147 to the second bevel gear 148, and the transmission ratio of the third bevel gear 149 to the fourth bevel gear 143 is not equal to 1. So that the rotational speed of the fourth bevel gear 143 is not equal to the rotational speed of the motor. By adjusting the transmission ratio, it helps to achieve speed reduction and torque increase. In this example, the second cylindrical gear 153 is the power input end of the intermediate transmission member 144.

[0141] Figure 10 The sizes of the first cylindrical gear 152 and the second cylindrical gear 153 in [[ ]] are only for illustration, and it does not mean that the diameter of the first cylindrical gear 152 must be larger than that of the second cylindrical gear 153.

[0142] Optionally, the first cylindrical gear 152 and the second cylindrical gear 153 are respectively a spur gear, a helical gear, a herringbone gear, etc.

[0143] In other examples, the first bevel gear 147 and the second bevel gear 148, the third bevel gear 149 and the fourth bevel gear 143, and the first cylindrical gear 152 and the second cylindrical gear 153 can respectively be replaced by a pair of crown gears or a worm and worm gear.

[0144] Refer to Figure 8 and Figure 9, optionally, in a state where the chain drive member 141 is connected to the container 100, two sets of chain drive members 141 are arranged at intervals along the length direction D1 of the container 100. Accordingly, a pair of running sprockets 129 are provided at the lower part of each photovoltaic panel member 121. The pair of running sprockets 129 are respectively arranged corresponding to a pair of chain drive members 141.

[0145] See Figure 8 , optionally, the chain 142 can adopt a double-row chain 142. Two running sprockets 129 are provided at the part of the photovoltaic panel member 121 corresponding to the same double-row chain 142.

[0146] See Figure 3 、 Figure 6 and Figure 8 , optionally, the running sprocket 129 is an incomplete gear.

[0147] Optionally, the photovoltaic cabin 101 is adapted to accommodate the chain drive member 141 in a disassembled state. In this way, the chain drive member 141 can be loaded into the photovoltaic cabin 101 after being disassembled as a whole, which is convenient for transportation, thereby reducing the transportation cost.

[0148] See Figure 11 , in addition, the automatic retractable photovoltaic device further includes a motor controller. The motor controller is electrically connected to the motor. The motor controller is configured to control the start and stop of the motor. The motor controller includes 2 buttons, and the 2 buttons are respectively used to control the forward and reverse rotation of the motor. By controlling the forward / reverse rotation of the motor, the forward and reverse rotation of the driving sprocket 157 is driven, so as to drive the running sprocket 129 of the photovoltaic panel assembly 120 to move away from or close to the chassis 106 along the direction of the chain 142, thereby achieving the purpose of unfolding and storing the photovoltaic panel assembly 120. The motor controller here is the second control device 187 to be described below. Since the description of the second control device 187 below is clearer, it will not be described in detail here.

[0149] See Figures 1 to 11 , the working principle of the unfolding and folding of the photovoltaic panel assembly 120 is as follows:

[0150] When the driving sprocket 157 rotates towards the outside of the box, it can drive the chain 142 to move. When the traveling sprocket 129 at the bottom of the outermost photovoltaic panel member 121 of the photovoltaic panel assembly 120 meshes with the chain 142, the bottom of the first photovoltaic panel member 121 moves towards the outside of the box along with the chain 142. After the limiting member 126 between this photovoltaic panel member 121 and the adjacent second photovoltaic panel member 121 extends to the extreme limit, the force will be transmitted to the second photovoltaic panel member 121 and drive it to move outwards. The bottom of the second photovoltaic panel member 121 is connected to the bottom of the third photovoltaic panel member 121, so the bottom of the third photovoltaic panel member 121 will move outwards along with the second photovoltaic panel member 121, and the gear plate at its bottom will fall onto the chain 142. Continuously in this way, the photovoltaic panel assembly 120 completes the unfolding action.

[0151] When the photovoltaic panel assembly 120 is stored, the action is opposite. The driving sprocket 157 rotates towards the inside of the box, driving the photovoltaic panel member 121 closest to the container 100 to move towards the inside of the box. The limiting rod at the top of the photovoltaic panel member 121 closest to the container 100 will drive the subsequent second photovoltaic panel member 121 to move towards the inside of the box. Continuously in this way, the folding and storage actions are completed.

[0152] The automatic retractable photovoltaic device according to the present application can be applied not only to photovoltaic containers but also to photovoltaic power generation containers.

[0153] Refer to Figure 1 and Figure 11 As shown in FIGS. and, by way of example, the energy storage device 160 includes a battery cluster 161. The battery cluster 161 includes a battery rack 162 and a plurality of energy storage batteries 163 arranged along the vertical direction D3. A hybrid inverter 164 and a first control device 165 are also provided in the energy storage compartment 102. The hybrid inverter 164 is electrically connected to the photovoltaic panel assembly 120 and the energy storage batteries 163 to perform DC-DC conversion on the electric energy of the photovoltaic panel assembly 120 and charge the energy storage batteries 163. A socket 166 is provided outside the container 100. The hybrid inverter 164 is electrically connected to the socket 166 via the first control device 165 to perform DC-AC conversion on the electric energy of the energy storage batteries 163 and supply power to the socket 166 and the devices inside the container 100. The socket 166 is divided into a three-phase power supply and a single-phase power supply to meet the requirements of different power usage scenarios.

[0154] Among them, the hybrid inverter 164 is also electrically connected to the motor via the first control device 165. The second control device 187 is electrically connected to the first control device 165. The second control device 187 is used to control the operation and stop of the motor. There are two buttons, "ON / OFF", provided on the second control device 187. When the "ON" button is pressed, the motor rotates forward to automatically deploy the photovoltaic panel assembly 120. When the button is released, the motor stops working. On the contrary, when the "OFF" button is pressed, the motor rotates in reverse to fold and store the photovoltaic panel assembly 120.

[0155] Optionally, the first control device 165 includes a circuit breaker. After being protected by the circuit breaker in the control box, the AC power converted by the hybrid inverter 164 is connected to the socket 166 outside the box through a cable. The socket 166 is divided into three-phase power and single-phase power to meet the requirements of different power usage scenarios. The socket 166 is of IP65 waterproof type and is equipped with a matching plug. All cable connections between the photovoltaic device 110 and the energy storage device 160, and between the energy storage device 160 and the socket 166 in the container 100 have been completed. During on-site deployment, after the photovoltaic panel assembly 120 is automatically deployed through the second control device 187, the power-taking cable only needs to be connected to the socket 166 to complete the deployment of the microgrid container 100, greatly saving the deployment time and difficulty and having the performance of fast mobility.

[0156] Refer to Figure 11 , a fire extinguishing container 171, a fire pipeline 172, a sprinkler head 173, a smoke detector 174, a second control device 175, and a fire solenoid valve 176 are also provided in the energy storage compartment 102. The fire extinguishing container 171 contains a gaseous fire extinguishing agent. The fire extinguishing container 171 is connected to the fire pipeline 172. At least part of the fire pipeline 172 is distributed on the top of the energy storage compartment 102. For example, if the fire extinguishing container 171 is located at the bottom of the energy storage compartment 102, the fire pipeline 172 further includes a pipeline section arranged along the upward direction. The sprinkler head 173 is located on the top of the energy storage compartment 102 and is connected to the fire pipeline 172. The smoke detector 174 is located on the top of the energy storage compartment 102 and is electrically connected to the second control device 175. The fire solenoid valve 176 is connected to the gas outlet end of the fire extinguishing container 171 and is electrically connected to the second control device 175. The second control device 175 is used to control the fire solenoid valve 176 to switch from the closed state to the open state when the smoke detector 174 is triggered. The second control device 175 has a motor controller with a PLC control chip inside, which can run a preset fire control program to achieve an automated fire control function.

[0157] Optionally, the fire container 171 is a fire extinguisher cylinder. The number of smoke detectors 174 is multiple. The fire control method can be set as follows: when more than two smoke detectors 174 trigger a fire signal, the second control device 175 controls the fire extinguisher cylinder to release a gaseous fire extinguishing agent, which is ejected from the sprinkler head 173 to achieve fire extinguishing.

[0158] Continue to refer to Figure 11 Furthermore, the photovoltaic container further includes an audible and visual alarm 177. The audible and visual alarm 177 is located outside the container 100. The audible and visual alarm 177 is electrically connected to the second control device 175. The second control device 175 is configured to control the audible and visual alarm 177 to emit audible and visual information when the smoke detector 174 is triggered. The audible and visual information includes at least one of ringing, flashing, text information, and pattern information.

[0159] Refer to again Figure 11 Furthermore, the photovoltaic container further includes a manual controller 178. The manual controller 178 is located outside the container 100. The manual controller 178 is electrically connected to the second control device 175. The manual controller 178 is used to be operated to enable the second control device 175 to control the fire solenoid valve 176 to switch from the closed state to the open state. When the smoke detector 174 fails, the second control device 175 can also be controlled by the manual controller 178 to release the gaseous fire extinguishing agent in the fire extinguisher cylinder.

[0160] Refer to again Figure 11 Furthermore, the photovoltaic container further includes an explosion vent panel 179. The explosion vent panel 179 is fixed to the top of the energy storage compartment 102. When a fire occurs and the pressure in the compartment suddenly rises, the explosion vent panel 179 at the top of the energy storage compartment 102 can burst when a preset value is reached, ensuring that the side wall 108 of the box body or the energy storage compartment door 105 will not be broken due to excessive pressure in the compartment, thus not causing harm to the surrounding personnel. At the same time, it can also ensure that the partition wall 103 of the box body will not be broken due to excessive pressure in the compartment and damage the photovoltaic device 110. This can improve the safety of the photovoltaic container.

[0161] Refer to again Figure 11, in some embodiments, the photovoltaic container further includes a temperature detector 181, an intake fan 182, an exhaust fan 183, and a first control device 165. The temperature detector 181 is disposed inside the energy storage compartment 102. The intake fan 182 is disposed at the lower part of the energy storage compartment door 105. The intake fan 182 is used to supply air into the interior of the energy storage compartment 102. The exhaust fan 183 is disposed at the upper part of the energy storage compartment door 105. In short, the position of the exhaust fan 183 in the vertical direction D3 is higher than that of the intake fan 182. The exhaust fan 183 is used to exhaust air from the energy storage compartment 102 to the outside. In the case where the energy storage compartment door 105 is a double-leaf door, the intake fan 182 and the exhaust fan 183 can be respectively disposed on the two energy storage compartment doors 105. The first control device 165 is disposed inside the energy storage compartment 102. In the figure, the first control device 165 is disposed on the partition wall 103. The first control device 165 is electrically connected to the temperature detector 181, the intake fan 182, and the exhaust fan 183. The first control device 165 is used to control the states of the intake fan 182 and the exhaust fan 183 according to the temperature detected by the temperature detector 181.

[0162] Referring again to Figure 11 , further, the photovoltaic container further includes an air conditioner 184. The air conditioner 184 is disposed on the energy storage compartment door 105. The first control device 165 is electrically connected to the temperature detector 181 and the air conditioner 184. The first control device 165 is used to control the state of the air conditioner 184 according to the temperature detected by the temperature detector 181. The first control device 165 monitors the temperature inside the energy storage compartment 102 in real time through the temperature detector 181 and adjusts the temperature inside the energy storage compartment 102 within a preset temperature range such as 0°C to 30°C. The temperature is preferably reduced by driving the air circulation inside the compartment by the fan. When the fan can no longer control the temperature inside the compartment, the air conditioner 184 will intervene to cool down. With this strategy, the self-consumption of electric energy is saved.

[0163] Referring again to Figure 11 , exemplarily, an emergency stop button 185 is provided outside the container 100. When a power supply failure occurs, pressing the emergency stop can disconnect the power supply between the energy storage battery 163 and the first control device 165. At that time, except for the power consumption of the second control device 175, all loads including the retracting and extending drive assembly 140 are powered off, thereby ensuring power consumption and personnel safety.

[0164] Referring to Figure 1 , Figure 2 and Figure 4 , exemplarily, the photovoltaic compartment door 104 is a wing-type side-opening door structure. The photovoltaic compartment door 104 is composed of a side wall 108 and a part of the top plate 107. The cross section is L-shaped. The photovoltaic compartment door 104 is pivotally connected to the top plate 107 around an axis parallel to the length direction D1 of the container 100, forming a "wing door" mechanism that can be rotated and opened.
