However, foldable photovoltaic (PV) devices in related technologies often rely on manual operation, resulting in low deployment efficiency. Separating energy storage devices from PV equipment leads to high transportation and maintenance costs, as well as significant difficulties and low efficiency in on-site deployment.

[0003] Therefore, there is a need to provide a photovoltaic-storage microgrid container to at least partially solve the above problems. Utility Model Content

However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0096] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art.

[0097] It should be understood that the terminology used herein is intended only to describe particular embodiments and is not intended to limit the scope of the invention. The singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise.

Furthermore, for example, the term "first component" does not imply the existence of a "second component," and the term "second component" does not imply the existence of a "first component." It should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," and similar expressions used in this utility model are for illustrative purposes only and are not intended to be limiting.

[0099] The terms “center,” “parallel,” “perpendicular,” “aligned,” and “symmetrical” used in this invention do not have to be precise, but can include typical engineering tolerances.

[0100] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0101] Traditional photovoltaic (PV) systems typically employ fixed installations, resulting in poor deployment flexibility. Existing foldable PV devices largely rely on manual operation, leading to low deployment efficiency. The separation of energy storage and PV equipment results in high transportation and maintenance costs. Assembly requires numerous cables and on-site technical personnel, necessitating significant manpower and time. Installation of auxiliary equipment also occupies surrounding space, further compromising convenience and mobility. These systems cannot meet the needs of emergency power supplies and off-grid power supply in remote areas. Therefore, there is an urgent need for a highly integrated, modular PV-storage microgrid container that can be deployed with a small team, providing plug-and-play functionality, intelligent charge / discharge switching, and multiple safety protections.

[0102] To at least partially solve the above problems, this utility model provides a photovoltaic-storage microgrid container 100.

[0103] The purpose of this invention is to address the problems of low efficiency and long installation time of manual deployment at project sites, large land area required due to the separate design of energy storage systems and photovoltaic equipment, and poor coordination involving civil engineering. This problem is solved through a technical approach that integrates containerized safe transportation, automated photovoltaic panel installation, and the integration of power generation and energy storage devices. This photovoltaic-storage microgrid container is a photovoltaic power generation system and integrated energy storage management device with automatic deployment capabilities, suitable for emergency power supply, off-grid power supply, and field operations.

[0104] See Figures 1 to 15 According to an embodiment of the present invention, the photovoltaic-storage microgrid container 100 includes a container 100, a photovoltaic device 110, and an energy storage device 160.

[0105] Container 100 includes a base frame 106, side walls 108, a top plate 107, and a partition wall 103 located inside the container 100. The container 100 has photovoltaic compartments 101 and energy storage compartments 102 arranged at intervals along the length direction D1 of the container 100. The photovoltaic compartments 101 and energy storage compartments 102 are separated by the partition wall 103. A closable photovoltaic compartment door 104 is provided on the side of the container 100 along the width direction D2. The photovoltaic compartment door 104 is arranged corresponding to the photovoltaic compartment 101. A closable energy storage compartment door 105 is provided at one end of the container 100 along the length direction D1. The energy storage compartment door 105 is arranged corresponding to the energy storage compartment 102.

[0106] The photovoltaic equipment 110 includes a photovoltaic panel assembly 120, a guide rail assembly 130, and a retraction / deployment drive assembly 140. The guide rail assembly 130 and the retraction / deployment drive assembly 140 each have a disassembled state and an assembled state. The disassembled state can be understood as the guide rail assembly 130 and the retraction / deployment drive assembly 140 being disassembled into several modular independent structures. The assembled state can be understood as the guide rail assembly 130 and the retraction / deployment drive assembly 140 having completed the assembly of their respective modular independent structures and being connected to the container 100 for on-site deployment. The guide rail assembly 130 and the retraction / deployment drive assembly 140 in the disassembled state are suitable for placement in the photovoltaic compartment 101. The guide rail assembly 130 and the retraction / deployment drive assembly 140 in the assembled state extend outside the photovoltaic compartment 101 along the width direction D2 of the container 100, allowing the photovoltaic panel assembly 120 to slide and connect to the guide rail assembly 130 along the width direction D2 of the container 100. The retraction drive assembly 140 is driven to the photovoltaic panel assembly 120, enabling the photovoltaic panel assembly 120 to switch between a use state and a storage state. When in use, the photovoltaic panel assembly 120 moves out of the photovoltaic compartment 101 and unfolds. When in storage, the photovoltaic panel assembly 120 moves into the photovoltaic compartment 101 and folds.

[0107] Energy storage device 160 is located in energy storage compartment 102. Energy storage device 160 is electrically connected to photovoltaic device 110 to store electrical energy.

[0108] When the photovoltaic compartment door 104 is opened, the photovoltaic panel assembly 120, the guide rail assembly 130, and the retraction drive assembly 140 can be deployed outside the photovoltaic compartment 101, or stored inside the energy storage compartment 101 for transportation. With both the photovoltaic compartment door 104 and the energy storage compartment door 105 closed, the entire container can be transported.

[0109] According to the present invention, the photovoltaic-storage microgrid container 100 can accommodate the photovoltaic compartment 101 in its disassembled state, and the photovoltaic panel assembly 120 is located in the photovoltaic compartment 101 in its stowed state, while the energy storage device 160 is located in the energy storage compartment 102. This allows for the integration of the photovoltaic device 110 and the energy storage device 160 within the container 100, thereby reducing transportation and maintenance costs. Furthermore, since the photovoltaic panel assembly 120 can switch between its operational and stowed states when the guide rail assembly 130 and the stowage drive assembly 140 are in their assembled state, this effectively reduces the difficulty of on-site deployment and improves the efficiency of on-site deployment.

[0110] See Figure 1 , Figure 2 , Figure 4 as well as Figure 5 For example, the photovoltaic panel assembly 120 includes a plurality of cascaded photovoltaic panel members 121 and a plurality of deployment limiting members 126. In 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 other 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 two photovoltaic panel members 121. The two 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 a foldable structure. The deployment limiting member 126 includes a first limiting rod 127 and a second limiting rod 128 hinged to each other. The ends of the first limiting rod 127 and the second limiting rod 128 closest to each other have a stop structure that can be rotated and limited relative to each other. When adjacent photovoltaic panel components 121 are unfolded to their 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 continuing to pivot relative to the second limiting rod 128. To prevent two adjacent photovoltaic panel components 121 from jamming during the folding process and becoming unable to fold, the included angle between the first limiting rod 127 and the second limiting rod 128 is less than 180° when the stop structure of the first limiting rod 127 abuts against the stop structure of the second limiting rod 128. This ensures that after the photovoltaic panel assembly 120 is unfolded, the included angles with downward openings among all adjacent photovoltaic panel components 121 are kept as consistent as possible.

[0111] See Figure 4 , Figure 6 , Figure 9 , Figure 10 as well as Figure 12In some embodiments, the take-up and take-down drive assembly 140 includes a chain drive member 141. The chain drive member 141 is detachably connected to the container 100. With the chain drive member 141 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. The chain drive member 141 includes a chain 142. The photovoltaic panel assembly 120 includes a plurality of cascaded photovoltaic panel members 121. The lower portion of each photovoltaic panel member 121 has a traveling sprocket 129. The traveling sprocket 129 is adapted to engage with the chain 142 so that the photovoltaic panel member 121 can move with the chain 142. That is, during the movement of the chain 142, the chain 142 can drive the lower portion of the photovoltaic panel member 121 to move, thereby pulling the photovoltaic panel member 121 out of or into the container 100. The photovoltaic panel component 121 moves away from the container 100 to unfold the photovoltaic panel assembly 120, thereby switching the photovoltaic panel assembly 120 to the use state. The photovoltaic panel component 121 moves towards the container 100 to fold the photovoltaic panel assembly 120, thereby switching the photovoltaic panel assembly 120 to the storage state. With the guide rail assembly 130 and chain drive component 141 assembled into the container 100, the length of the guide rail assembly 130 along the width direction D2 is not less than the length of the chain drive component 141 along the width direction D2.

[0112] See Figure 1 and Figure 4 Optionally, along 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 not less than the length of the portion of the chain drive member 141 located outside the container 100 along the width direction D2. When the included angle between two adjacent upperly hinged photovoltaic panel members 121 reaches its maximum, the distance between the lower parts 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 along the width direction D2.

[0113] See Figure 6 , Figure 7 , Figure 9 , Figure 10 as well as Figure 12Exemplarily, the chain drive assembly 141 further includes a drive sprocket 157, a driven sprocket 158, and a chain drive frame 159. The chain drive frame 159 is adapted to be detachably connected to the base frame 106. The drive sprocket 157 is rotatably connected to one end of the chain drive frame 159. The driven sprocket 158 ​​is rotatably connected to the other end of the chain drive frame 159. The drive sprockets 157 and 158 are spaced apart. A chain 142 is wound around the drive sprockets 157 and 158. The take-up and take-down drive assembly 140 also includes a drive member 151 and an intermediate transmission member 144. The drive member 151 is located inside the container 100. One end of the intermediate transmission member 144 is connected to the drive member 151. The other end of the intermediate transmission member 144 is adapted to be connected to the drive sprocket 157 to transmit power from the drive member 151 to the drive sprocket 157. When the drive component 151 outputs power, it can drive the drive sprocket 157 to rotate, thereby driving the chain 142 to move in a cycle, so as to drive each photovoltaic panel component 121 to move. It should be noted that one end of the intermediate transmission component 144 is the power input end of the intermediate transmission component 144, and the other end of the intermediate transmission component 144 is the power output end of the intermediate transmission component 144.

[0114] Optionally, the drive member 151 is disposed on the upper part of the base frame 106. The base frame 106 has a cavity located below the floor. A portion of the intermediate transmission member 144 is located within the cavity to reduce the space occupied by the photovoltaic compartment 101.

[0115] It should be noted that the terms "driving sprocket 157" and "driven sprocket 158" are relative, and the sprocket that serves as the power input structure is usually referred to as the driving sprocket. In this embodiment, the sprocket connected to the intermediate transmission member 144 is considered the driving sprocket.

[0116] Optionally, the chain drive frame 159 is detachably connected to the bottom side beam of the base frame 106 by fasteners such as bolts.

[0117] Continue reading Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 12 as well as Figure 15Furthermore, the drive component 151 is an electric motor. The electric motor is located in the energy storage compartment 102. The intermediate transmission component 144 includes a first transmission shaft 145, a second transmission shaft 146, a first bevel gear 147, a second bevel gear 148, and a third bevel gear 149. 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. The second bevel gear 148 and the third bevel gear 149 are both fixed to the second transmission shaft 146. The second bevel gear 148 meshes with the first bevel gear 147. The take-up and take-down drive assembly 140 also includes a fourth bevel gear 143. The fourth bevel gear 143 is directly or indirectly connected to the drive sprocket 157. When the chain drive component 141 is connected to the container 100, the fourth bevel gear 143 meshes with the third bevel gear 149. Here, the power is transmitted between the first drive shaft 145 and the second drive shaft 146 through the cooperation of the first bevel gear 147 and the second bevel gear 148. The power is transmitted between the second drive shaft 146 and the drive sprocket 157 through the cooperation of the third bevel gear 149 and the fourth bevel gear 143, ultimately transmitting the power to the chain 142, causing the chain 142 to move. It should be noted that the fourth bevel gear 143 is indirectly connected to the drive sprocket 157; this can be understood as the fourth bevel gear 143 being connected to the drive sprocket 157 through a relay transmission structure. This relay transmission structure can be a gear drive or other transmission methods. The fourth bevel gear 143 is the other end of the intermediate transmission component 144, that is, the power output end of the intermediate transmission component 144.

[0118] In the illustrated example, there are two sets of chain drive components 141. In the application state of the automatic photovoltaic device, the two sets of chain drive components 141 are arranged axially spaced along the first drive shaft 145, and both sets of chain drive components 141 extend in a direction perpendicular to the first drive shaft 145. The intermediate drive component 144 includes a first drive shaft 145, two sets of second drive shafts 146, two sets of first bevel gears 147, two sets of second bevel gears 148, two sets of third bevel gears 149, and two sets of fourth bevel gears 143. The two sets of second drive shafts 146 are parallel to each other and arranged axially spaced along the first drive shaft 145. The two sets of first bevel gears 147 are arranged axially spaced along the first drive shaft 145. The two sets of second bevel gears 148 are respectively located at the ends of the two sets of second drive shafts 146 near the first drive shaft 145. The two sets of third bevel gears 149 are respectively located at the ends of the two sets of second drive shafts 146 away from the first drive shaft 145. Two sets of fourth bevel gears 143 are respectively installed on two sets of chain drive components 141.

[0119] In other examples, the number of chain drive components 141 may be three or more. Accordingly, the number of each of the second drive shaft 146, the first bevel gear 147, the second bevel gear 148, the third bevel gear 149, and the fourth bevel gear 143 is matched with the number of chain drive components 141.

[0120] See Figure 6 , Figure 9 , Figure 10 as well as Figure 15 Furthermore, the second drive shaft 146 includes a first shaft segment 146a and a second shaft segment 146b. The second shaft segment 146b is detachably connected to the first shaft segment 146a. At least a portion of the first shaft segment 146a is adapted to be disposed within the clamping cavity of the base frame 106. At least a portion of the second shaft segment 146b is adapted to be disposed outside the base frame 106. A first bevel gear 147 is fixed to the first drive shaft 145. A second bevel gear 148 is fixed to the first shaft segment 146a. The second bevel gear 148 meshes with the first bevel gear 147. A third bevel gear 149 is fixed to the second shaft segment 146b. Figure 6 and Figure 10 The first shaft segment 146a and the second shaft segment 146b are connected by a bearing located at the base frame 106. Specifically, the first shaft segment 146a and the second shaft segment 146b are detachably connected to the inner ring of the bearing via splines, flat keys, or other keyed connections, thereby enabling the transmission connection and disassembly of the first shaft segment 146a and the second shaft segment 146b. Alternatively, the first shaft segment 146a and the second shaft segment 146b can be detachably connected via splines, flat keys, or other keyed connections, such as... Figure 15 As shown. With the first shaft segment 146a assembled to the base frame 106, the end of the first shaft segment 146a is exposed on the side of the bottom side beam, or the end of the first shaft segment 146a is located in a position that allows for easy docking with the second shaft segment 146b. The second shaft segment 146b and the third bevel gear 149 are constructed as a single unit, or the second shaft segment 146b and the third bevel gear 149 are detachably connected.

[0121] Optionally, to prevent the first shaft segment 146a and the second shaft segment 146b from disengaging from each other along the axial direction of the second drive shaft 146, the first shaft segment 146a and the second shaft segment 146b are locked together by a locking screw. Specifically, the end of the first shaft segment 146a is provided with a spline hole and a locking hole. The locking hole extends from the outer surface of the first shaft segment 146a along the radial direction of the first shaft segment 146a to the spline hole. The locking hole is a threaded hole. The end of the second shaft segment 146b is provided with a spline portion, which is adapted to be inserted into the spline hole. The spline portion is provided with a locking groove corresponding to the locking hole or another locking hole. After the second shaft segment 146b and the first shaft segment 146a are inserted, the locking screw passes through the locking hole and is tightened until the locking screw enters the locking groove or another locking hole.

[0122] Continue reading Figure 6 , Figure 9 , Figure 10 as well as Figure 15 Accordingly, to facilitate the docking of the first shaft segment 146a and the second shaft segment 146b, and to support the assembled second drive shaft 146, the bottom side beam of the base frame 106 in this embodiment has a groove with an opening facing outward along the width direction D2 of the container 100. The groove of the bottom side beam is used to fix and install bearing seats, and the bearing seats do not extend beyond the side of the bottom side beam, which is beneficial to improving the space utilization of the bottom side beam. For this purpose, the bottom side beam includes channel steel or H-beams. Compared to using square tubes, using channel steel or H-beams, which have their own grooved structure, is more advantageous in meeting the requirements of the grooved structure while maintaining structural strength, and also facilitates anti-corrosion treatment.

[0123] To ensure a reliable connection between the chain drive component 141 and the bottom side beam, the bottom side beam also includes a sealing plate with flange holes. The sealing plate is welded to the groove of a channel steel or H-beam to seal part of the groove. The sealing plate is used to assemble with the chain drive frame 159 by means of bolting, riveting, or other methods.

[0124] See Figure 8 and Figure 9 Optionally, the deployment / retraction drive assembly 140 includes a pair of chain drive members 141. With the chain drive members 141 connected to the container 100, the pair of chain drive members 141 are spaced apart along the length direction D1 of the container 100. Correspondingly, each photovoltaic panel member 121 has a pair of traveling sprockets 129 at its lower part. The pair of traveling sprockets 129 are respectively arranged corresponding to the pair of chain drive members 141.

[0125] See Figure 8 Optionally, the chain 142 can be a double-row chain. Two traveling sprockets 129 are provided at the part of the photovoltaic panel component 121 corresponding to the same double-row chain.

[0126] See Figure 6 and Figure 7In addition, the chain drive component 141 also includes a support 154 and a limiter 156. After the chain drive component 141 is bolted to the bottom side beam of the container 100, it ensures that the drive sprocket 157 is aligned with the traveling sprocket 129 of the photovoltaic panel component 121. When the drive sprocket 157 rotates, it drives the traveling sprocket 129 to move along the extension direction of the guide rail assembly 130. The limiter 156 below the chain 142 is padded with a support 154 to prevent the lower chain 142 from directly rubbing against the metal bracket, thus extending the service life of the chain drive component 141. An guide 155 is provided on the limiter 156 near the container end. A nylon block is padded on the inner side of the guide 155. The nylon block defines a guide groove 155c. The guide groove 155c is aligned with the chain 142 along the length direction of the chain drive component 141. The opening width of the guide groove 155c decreases from both ends to the middle. The guide groove 155c is adapted for the passage of the traveling sprocket 129. In other words, the guide groove 155c has a flared shape that gradually narrows from both ends to the middle along the length of the chain drive component 141. By providing the inlet 155, it is easier to position the photovoltaic panel component 121 in a horizontal position perpendicular to the guide direction, thereby facilitating more accurate docking of the traveling sprocket 129 below the photovoltaic panel component 121 with the chain 142. Overall, the two ends of the guide groove 155c are flared, which facilitates the traveling sprocket 129 of the photovoltaic panel component 120 falling into or out of the chain drive component 141. The inlet 155 has a receiving notch 155a suitable for accommodating the base frame 106.

[0127] In this embodiment, the support 154 is a resin board.

[0128] In other embodiments, the support member 154 may be a plate made of other non-metallic materials.

[0129] See Figure 3 , Figure 6 as well as Figure 8 Optionally, the traveling sprocket 129 is an incomplete gear.

[0130] Optionally, the photovoltaic compartment 101 is adapted to accommodate the chain drive component 141 in its disassembled state. This allows the chain drive component 141 to be disassembled as a whole and then installed inside the photovoltaic compartment 101 for easy transportation, thereby reducing transportation costs.

[0131] See Figure 10Exemplarily, the output shaft of the electric motor is connected to a first cylindrical gear 152. A second cylindrical gear 153 is fixed to a first drive shaft 145. The first cylindrical gear 152 meshes with the second cylindrical gear 153. The number of teeth of the first cylindrical gear 152 is greater than the number of teeth of the second cylindrical gear 153. This increases the rotational speed of the first drive shaft 145, thereby helping to improve the efficiency of the photovoltaic panel assembly 120 in unfolding and folding. In this example, the second cylindrical gear 153 is the power input end of the intermediate transmission member 144.

[0132] See Figure 1 , Figure 3 , Figure 13 as well as Figure 14 For example, the guide rail assembly 130 includes a plurality of guide rail members 131, a plurality of guide rail brackets 132, and a plurality of guide rail seats 133. The plurality of guide rail members 131 are adapted to be arranged along the length direction D1 of the guide rail members 131. The guide rail members 131 are detachably connected to the upper part of the guide rail brackets 132. The guide rail brackets 132 are provided at least at both ends of the guide rail members 131. The ends of two adjacent guide rail members 131 close to each other are connected to the same guide rail bracket 132. The lower part of the guide rail bracket 132 is detachably connected to the guide rail seat 133 by fasteners such as bolts. The guide rail seat 133 includes a connecting portion 133a and a mounting hole 133b. The connecting portion 133a is located at the end of the guide rail seat 133 to facilitate connecting two adjacent guide rail seats 133. The connecting portion 133a is suitable for use in environments with weak winds, eliminating the need to fix the guide rail seat 133 to the ground. Mounting hole 133b is suitable for fastening to the ground of the target site with fasteners to adapt to scenarios where strong winds require reinforcement. Photovoltaic compartment 101 is suitable for accommodating guide rail 131, guide rail bracket 132 and guide rail support 132 in the disassembled state.

[0133] Optionally, the connecting part 133a is a hole suitable for connecting ropes or cable ties. The mounting hole 133b is suitable for connecting bolts.

[0134] See Figure 3 and Figure 8Furthermore, the guide rail component 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. The lower wing plate 131c is connected to the lower part of the support plate 131b. The lower wing plate 131c is adapted to be connected to the guide rail bracket 132. Overall, the cross-sectional shape of the guide rail component 131 is "I" shaped or close to "I". The photovoltaic panel component 121 includes a photovoltaic panel component 122, a main roller 123, a secondary roller connector 124, and a secondary roller 125. The main roller 123 and the secondary roller connector 124 are both rotatably connected to the lower part of the photovoltaic panel component 122 about the axis of the main roller 123. The main roller 123 is adapted to contact the upper part of the upper wing plate 131a. A secondary roller connector 124 is provided at both ends of the main roller 123 in the axial direction. Each secondary roller connector 124 is provided with a secondary roller 125. The secondary roller 125 is rotatably connected to the secondary roller connector 124 about its axis. The axis of the secondary roller 125 is parallel to the axis of the main roller 123. The secondary roller 125 is adapted to contact the lower part of the upper flange 131a. By limiting the upper flange 131a in the vertical direction D3 by the main roller 123 and the secondary roller 125, the photovoltaic panel module 120 can be prevented from detaching from the guide rail assembly 130 in the vertical direction D3. The secondary roller connectors 124 on both sides of the main roller 123 can limit the horizontal displacement of the photovoltaic panel module 120. This can improve the wind resistance of the photovoltaic panel module 120.

[0135] See Figure 5 Optionally, the photovoltaic panel module 120 is provided with fixing rings 111 on both sides perpendicular to the direction of extension and retraction, so as to be suitable for connection to a fixed object by ropes. Users can add ropes and ground stakes according to the wind level and attach them to the fixing rings 111 to further increase the wind resistance of the photovoltaic panel module 120.

[0136] Furthermore, limiting portions extending downward to the lower wing plate 131c are formed on both sides of the upper wing plate 131a. The limiting portions are spaced apart from the lower wing plate 131c. The auxiliary roller 125 is adapted to be arranged between the support plate 131b and the limiting portions. This can further limit the horizontal displacement of the photovoltaic panel module 120, which helps to enhance the wind resistance of the photovoltaic panel module 120.

[0137] Optionally, each auxiliary wheel connector 124 is provided with at least two auxiliary rollers 125. The axes of all auxiliary rollers 125 are coplanar. Multiple auxiliary rollers 125 can increase the load-bearing capacity, thereby adapting to the wind resistance requirements under higher wind force levels.

[0138] exist Figure 3 and Figure 8In the example shown, each auxiliary wheel connector 124 connects to two auxiliary rollers 125. The main roller 123 rests on the track, with the auxiliary wheel connectors 124 on both sides of the main roller 123 close to the sides of the track and maintaining a slight gap. The auxiliary rollers 125 are mounted inside the auxiliary wheel connectors 124. This ensures that the roller mechanism is relatively locked to the track, preventing the rollers from deviating from the track due to external forces. In this way, the photovoltaic panel assembly 120 can lock with the guide rail assembly 130 after deployment, providing a certain degree of wind resistance.

[0139] See Figure 9 Optionally, the number of guide rail assemblies 130 is two sets. The two sets of guide rail assemblies 130 are respectively arranged corresponding to the two ends of the photovoltaic panel 122 in the horizontal direction. The photovoltaic panel component 121 includes two sets of main rollers 123, two sets of auxiliary roller connectors 124, and two sets of auxiliary rollers 125. The two sets of main rollers 123, the two sets of auxiliary roller connectors 124, and the two sets of auxiliary rollers 125 are each arranged corresponding to the two sets of guide rail assemblies 130.

[0140] See Figure 4 Optionally, a portion of the guide rail 131 of the guide rail assembly 130 is fixed to the upper part of the base frame 106 inside the photovoltaic compartment 101 to support the photovoltaic panel assembly 120 and to allow the photovoltaic panel assembly 120 to move within the photovoltaic compartment 101 along the width direction D2 of the container 100.

[0141] Specifically, the top of the first photovoltaic panel component 121 inside the box is connected to the top of the second photovoltaic panel component 121 by a hinge, forming a rotatable structure. The bottom of the second photovoltaic panel component 121 is connected to the bottom of the third photovoltaic panel component 121 by a hinge, forming a rotatable structure. Multiple panels are cascaded in this manner, extending outwards from the box to form a photovoltaic panel assembly 120. In the direction from inside the box to outside, the bottom of all photovoltaic panel components 121 with an odd number of positions is equipped with two pulley mechanisms, each pulley having a toothed plate on one side. The pulley mechanism includes the aforementioned main roller 123, auxiliary roller connector 124, and auxiliary roller 125. The toothed plate is a traveling sprocket 129. A guide rail 131 is fixed inside the photovoltaic compartment 101 to allow the photovoltaic panel components 121 to move from inside the box to outside. Two sets of extended guide rail assemblies 130 are installed on the ground of the photovoltaic storage compartment. The photovoltaic panel assembly 120 sits on the guide rail assembly 130 through a pulley mechanism and can slide along the extension direction of the guide rail assembly 130.

[0142] Optionally, the photovoltaic panel component 121 includes a photovoltaic frame and photovoltaic panels 122 connected to the frame. Adjacent photovoltaic panel components 121 are hinged to each other via their photovoltaic frames. Each photovoltaic frame can install a corresponding number of photovoltaic panels 122 as needed. This corresponding number can be one, two, three, or more than three. When each photovoltaic frame has two or more photovoltaic panels 122, the arrangement direction of each photovoltaic panel 122 can be horizontal, vertical, or two or more directions, including both horizontal and vertical directions. The photovoltaic frame can be square or other shapes. In this embodiment, the photovoltaic frame is rectangular. Furthermore, when installed in the container 100, the length direction of the photovoltaic frame is consistent with the length direction D1 of the container 100.

[0143] The following describes one assembly method of the guide rail assembly 130 and further elaborates on some specific structures of the guide rail assembly 130.

[0144] After the base frame 106 of container 100 is positioned, the parts of the guide rail assembly 130 below the photovoltaic panel assembly 120 are removed. First, the guide rail base 133 is spliced ​​end-to-end along the extension direction of the guide rail pieces 131 inside the container. Then, the guide rail brackets 132 are placed sequentially according to the bolt holes on the guide rail base 133. The segmented guide rail pieces 131 are aligned with the two guide rail pieces 131 welded to the base frame 106. The guide rail pieces 131 are then placed sequentially on the guide rail brackets 132, with the end of the first guide rail piece 131 and the beginning of the second guide rail piece 131 overlapping on the same guide rail bracket 132. The guide rail pieces 131 are then fixed to the guide rail brackets 132 with bolts. The guide rail brackets 132 are fixed to the guide rail base 133 with bolts. No orientation identification is required during splicing between the guide rail pieces 131, the guide rail brackets 132, and the guide rail bases, making assembly relatively convenient.

[0145] For guide rail bracket 132, such as Figure 13 and Figure 14 Two types of guide rail brackets 132 are shown, both of which have an inverted U-shaped structure and two opposing legs. Figure 14 In this design, the lower ends of the support legs are used to connect with the protruding portions on both sides of the guide rail base 133. The lower ends of the two support legs of the guide rail bracket 132 are provided with bent feet. Holes are formed on the feet. Correspondingly, another hole is formed on the protruding portion of the guide rail base 133. The connection between the guide rail bracket 132 and the guide rail base 133 is achieved by fasteners such as bolts and nuts passing through the holes in the feet and the holes in the guide rail base 133. The bending of the feet can be towards the direction closer to the other support leg (e.g., bending towards the other support leg). Figure 13 As shown), it can also bend away from the other leg (as shown). Figure 14 (As shown). In contrast, bending the legs away from the other leg increases the space for installation operations, thereby improving the flexibility and convenience of assembly, and thus helping to improve assembly efficiency.

[0146] For guide rail seat 133, the following can be adopted: Figure 13 He Ru Figure 14 Two different structures are shown. Figure 14 For example, the guide rail base 133 has flat portions, recessed portions, raised portions, and transition portions between them on both sides and in the middle. The recessed portions are lower than the raised portions. The recessed portions are connected to the raised portions through the transition portions. When the guide rail base 133 is placed on the ground, the recessed portions on both sides contact the ground, while the raised portions create a certain distance between them and the ground. The connection between the guide rail bracket 132 and the guide rail base 133 is located on the raised portions. Therefore, when the guide rail bracket 132 is bolted to the guide rail base 133, even if it helps to prevent the bolts from exceeding the lower surface of the guide rail base 133, it will not touch the ground, ensuring the stability of the base guide rail base 133. The guide rail base 133 includes three raised portions and two recessed portions. The three raised portions are arranged at intervals along the width direction of the guide rail base 133, and recessed portions are provided between adjacent raised portions. The raised portion in the middle is more conducive to ensuring the flatness of the recessed portions on both sides during processing. Therefore, the guide rail seat 133 has a multi-bend structure, which helps to increase the overall rigidity of the guide rail seat 133. The protruding parts at both ends are used to connect with the guide rail bracket 132. The guide rail seat 133 has pre-drilled holes at the positions of the protruding parts at the beginning and end of the guide rail seat 133 as connecting parts 133a. Cable ties can be passed through the holes to tie the beginning and end of the guide rail seat 133 together, thereby facilitating the assembly of the guide rail seats 133. The recessed part of the guide rail seat 133 is used to provide mounting holes 133b so that when the guide rail seat 133 is connected to the ground, foundation, etc. using fasteners, it can reliably contact the ground, foundation, etc.

[0147] See Figures 1 to 14 The working principle of unfolding and folding photovoltaic panel module 120 is as follows:

[0148] When the drive sprocket 157 rotates outwards, it drives the chain 142 to move. When the traveling sprocket 129 at the bottom of the outermost photovoltaic panel component 121 of the photovoltaic panel assembly 120 engages with the chain 142, the bottom of the first photovoltaic panel component 121 moves outwards with the chain 142. Once the deployment limiting member 126 between this photovoltaic panel component 121 and the adjacent second photovoltaic panel component 121 extends to its limit, force is transmitted to the second photovoltaic panel component 121, causing it to move outwards. The bottom of the second photovoltaic panel component 121 is connected to the bottom of the third photovoltaic panel component 121, so the bottom of the third photovoltaic panel component 121 moves outwards with the second photovoltaic panel component 121, and its bottom gear plate falls onto the chain 142. This process continues, and the photovoltaic panel assembly 120 completes its deployment.

[0149] When the photovoltaic panel assembly 120 is folded away, the action is reversed. The drive sprocket 157 rotates inward toward the container, causing the photovoltaic panel assembly 121 closest to the container 100 to move inward. The limiting rod at the top of the photovoltaic panel assembly 121 closest to the container 100 then causes the second photovoltaic panel assembly 121 to move inward. This process continues, thus completing the folding and folding action.

[0150] See Figure 1 and Figure 11 For 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 a vertical direction D3. A hybrid inverter 164 and a first control device 165 are also provided inside 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 convert the electrical energy from the photovoltaic panel assembly 120 into DC-DC power and charge the energy storage batteries 163. A socket 166 is provided on the exterior of the container 100. The hybrid inverter 164 is electrically connected to the socket 166 via the first control device 165 to convert the electrical energy from the energy storage batteries 163 into DC-AC power and supply power to the socket 166 and the equipment inside the container 100. The socket 166 is available in both three-phase and single-phase versions to meet the needs of different power consumption scenarios.

[0151] The hybrid inverter 164 is also electrically connected to the motor via a first control device 165. A 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. The second control device 187 is equipped with two buttons: "Open" and "Close". When the "Open" button is pressed, the motor rotates forward to automatically unfold the photovoltaic panel module 120. When the button is released, the motor stops operating. Conversely, when the "Close" button is pressed, the motor rotates in the reverse direction to fold and store the photovoltaic panel module 120.

[0152] Optionally, the first control device 165 includes a circuit breaker. The AC power converted by the hybrid inverter 164, after being protected by the circuit breaker inside the control box, is connected via cable to a socket 166 outside the box. The socket 166 is available in both three-phase and single-phase versions to meet the needs of different power usage scenarios. The socket 166 is IP65 waterproof and equipped with a matching plug. All cable connections are completed between the photovoltaic equipment 110 and the energy storage device 160 inside the container 100, and between the energy storage device 160 and the socket 166. During on-site deployment, after the photovoltaic panel modules 120 are automatically deployed via the second control device 187, the power supply cable can be connected to the socket 166 to complete the deployment of the microgrid container 100, greatly saving deployment time and difficulty, and providing rapid and mobile performance.

[0153] See Figure 11 The energy storage compartment 102 also includes a fire extinguishing container 171, a fire extinguishing pipe 172, a sprinkler head 173, a smoke detector 174, a second control device 175, and a fire solenoid valve 176. The fire extinguishing container 171 contains a gaseous extinguishing agent. The fire extinguishing container 171 is connected to the fire extinguishing pipe 172. At least a portion of the fire extinguishing pipe 172 is located at 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 extinguishing pipe 172 also includes a pipe section arranged in an upward direction. The sprinkler head 173 is located at the top of the energy storage compartment 102 and connected to the fire extinguishing pipe 172. The smoke detector 174 is located at the top of the energy storage compartment 102 and electrically connected to the second control device 175. The fire solenoid valve 176 is connected to the outlet of the fire extinguishing container 171 and 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 a closed state to an open state when the smoke detector 174 is triggered. The second control device 175 contains a control unit with a PLC control chip, which can run a preset fire control program to achieve automated fire control functions.

[0154] Optionally, the fire-fighting container 171 is a fire-fighting gas cylinder. The number of smoke detectors 174 can be multiple. The fire control method can be set such that when more than two smoke detectors 174 trigger a fire signal, a second control device 175 controls the fire-fighting gas cylinder to release gaseous extinguishing agent, which is then sprayed from the nozzle 173 to extinguish the fire.

[0155] Continue reading Figure 11 Furthermore, the photovoltaic-storage microgrid container 100 also includes an audible and visual alarm 177. The audible and visual alarm 177 is located on the exterior of the container 100. The audible and visual alarm 177 is electrically connected to a second control device 175. The second control device 175 is used 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 the following: a sound, a flashing light, text information, and graphic information.

[0156] See also Figure 11 Furthermore, the photovoltaic-storage microgrid container 100 also includes a manual controller 178. The manual controller 178 is located outside the container 100. The manual controller 178 is electrically connected to a second control device 175. The manual controller 178 is operated to cause the second control device 175 to control the fire-fighting solenoid valve 176 to switch from a closed state to an open state. When the smoke detector 174 fails, the manual controller 178 can also control the second control device 175 to release the gaseous extinguishing agent from the fire-fighting cylinder.

[0157] See also Figure 11 Furthermore, the photovoltaic-storage microgrid container 100 also includes a burst relief plate 179. The burst relief plate 179 is fixed to the top of the energy storage compartment 102. In the event of a fire and a sudden increase in internal pressure, the burst relief plate 179 on top of the energy storage compartment 102 can burst open upon reaching a preset value, ensuring that the excessive internal pressure will not breach the side wall 108 or the energy storage compartment door 105, thus preventing injury to surrounding personnel. Simultaneously, it also ensures that excessive internal pressure will not breach the partition wall 103 of the container, thereby preventing damage to the photovoltaic equipment 110. This enhances the safety of the photovoltaic-storage microgrid container 100.

[0158] See also Figure 11 In some embodiments, the photovoltaic-storage microgrid container 100 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 located inside the energy storage compartment 102. The intake fan 182 is located at the lower part of the energy storage compartment door 105. The intake fan 182 is used to supply air to the interior of the energy storage compartment 102. The exhaust fan 183 is located at the upper part of the energy storage compartment door 105. In short, the exhaust fan 183 is positioned higher than the intake fan 182 in the vertical direction D3. The exhaust fan 183 is used to exhaust air to the outside of the energy storage compartment 102. When the energy storage compartment door 105 is a double door, the intake fan 182 and the exhaust fan 183 can be correspondingly located on both energy storage compartment doors 105. The first control device 165 is located inside the energy storage compartment 102. In the figure, the first control device 165 is located 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 state of the intake fan 182 and the exhaust fan 183 according to the temperature detected by the temperature detector 181.

[0159] See also Figure 11Furthermore, the photovoltaic-storage microgrid container 100 also includes an air conditioner 184. The air conditioner 184 is located at the energy storage compartment door 105. A first control device 165 is electrically connected to a temperature detector 181 and the air conditioner 184. The first control device 165 controls the state of the air conditioner 184 based on 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 via the temperature detector 181 and adjusts the temperature inside the energy storage compartment 102 within a preset temperature range, such as 0℃ to 30℃. The temperature is lowered primarily by using a fan to circulate air within the compartment; when the fan can no longer control the temperature, the air conditioner 184 intervenes to cool the compartment. This strategy conserves energy.

[0160] See also Figure 11 For example, an emergency stop button 185 is provided on the exterior of the container 100. In the event of a power failure, pressing the emergency stop button will disconnect the power supply to the energy storage battery 163 and the first control device 165. At that time, all loads, including the retraction drive assembly 140, will be de-energized except for the second control device 175, thereby ensuring power supply and personnel safety.

[0161] See Figure 1 , Figure 2 and Figure 4 For example, the photovoltaic door 104 is a wing-type side-opening door structure. The photovoltaic door 104 consists of a side wall 108 and a portion of the top plate 107. The cross-section is L-shaped. The photovoltaic door 104 is pivotally connected to the top plate 107 about an axis parallel to the length direction D1 of the container 100, forming a rotatable "wing door" mechanism.

[0162] See Figure 1 , Figure 2 , Figure 4 as well as Figure 11 Furthermore, to enable electrically controlled opening and closing of the photovoltaic cabin door 104, an electric actuator 112 is installed inside the photovoltaic cabin 101. The electric actuator 112 is powered by a first control device 165 located in the energy storage cabin 102 and controlled by an open / close button on a first control device 186. When the corresponding "open" button on the first control device 186 is pressed, the electric actuator 112 extends, pushing the photovoltaic cabin door 104 to rotate around the hinge connected at the top to open. When the button is released, the electric actuator 112 is de-energized, the extension action immediately stops, and the photovoltaic cabin door 104 hovers in that position. When the corresponding "close" button on the first control device 186 is pressed, the electric actuator 112 retracts, pulling the photovoltaic cabin door 104 to rotate around the hinge connected at the top to close.

The extension rail here is an assembly of various guide rail components 131 arranged outside the container 100, and the accessories include guide rail brackets 132 and guide rail seats 133.

[0165] Upon arrival at the deployment location, first open the energy storage compartment door 105. The operator stands outside the container 100, operates the first controller box, and observes the container's status to control the opening of the photovoltaic compartment door 104.
