DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figure 1 As shown, a multi-row foldable energy storage container power generation system includes a photovoltaic module power generation system 1, a foldable multi-row support bracket 2, an energy storage container system 3, and an electrical equipment load end system. The photovoltaic module power generation system 1 includes a solar panel 11, and the solar panel 11 is correspondingly arranged on the foldable multi-row support bracket 2. The foldable multi-row support bracket 2 can be folded and retracted to be correspondingly placed in the energy storage container system 3. The energy storage container system 3 is electrically connected to the electrical equipment load end system, and the electrical equipment load end system is correspondingly arranged in the energy storage container system 3. The present invention achieves efficient space utilization and convenient transportation. Through the three-dimensional folding structure of the foldable multi-row support bracket 2, the bracket unit can be completely retracted and placed in the energy storage container system, solving the problems of insufficient folding rate of rigid trusses and low deployment efficiency caused by split transportation in the prior art, reducing the floor space and transportation volume, and improving the convenience of one-box integration.

[0028] like Figure 2 and Figure 3 As shown, the foldable multi-row support bracket 2 includes several foldable bracket units 21. The present invention can be used in series horizontally according to actual use requirements, and the bottom height of the rear bracket can be changed in the vertical direction. It can be used in an array matrix distribution to meet actual power supply needs. The arrangement can be updated and changed according to actual use conditions, and is suitable for powering multiple energy storage containers.

[0029] The foldable support unit 21 includes a main beam frame 22 and several sub-beam frames 23. Both sides of the main beam frame 22 are connected to the sub-beam frames 23 through long side folding components 24. One end of the main beam frame 22 is connected to several fixed components 25, and the other end of the main beam frame 22 is connected to several short side folding components 27. The fixed components 25 and the short side folding components 27 are respectively connected to the walking device 26. The long side folding component 24 includes a fixed connector 242 and a sliding component 241. One end of the fixed connector 242 and the sliding component 241 is connected to the main beam frame 22, and the other end of the fixed connector 242 and the sliding component 241 is connected to the sub-beam frame 23. The present invention adopts a main and sub-beam hinge linkage. The main beam frame 22 and the sub-beam frame 23 form a horizontal folding chain through the long side folding component 24, and the short side folding component 27 drives vertical folding to achieve two-way folding compression.

[0030] The foldable multi-arranged support bracket 2 of the present invention provides fast automatic deployment and installation capabilities, significantly shortening on-site deployment time. The foldable bracket unit 21 is controlled by electrical signals. The travel motor 264 drives the travel wheel 263 to move horizontally. At the same time, the power motors of the fixed component 25 and the short-side folding component 27 drive the folding action, causing the bracket to slowly unfold horizontally while moving; then, the travel motor of the sliding component 241 of the long-side folding component 24 drives the screw to rotate, pushing the sub-beam frame 23 to unfold vertically, and locking in steps to ensure stability. It solves the pain point of the existing technology that requires manual on-site assembly, realizes fully automated deployment, reduces labor time and operation and maintenance costs, and improves the response speed of emergency power supply scenarios.

[0031] like Figure 5 and Figure 7 As shown, the walking device 26 includes a horizontal plate 261, the two ends of which are respectively fixedly connected to the fixing assembly 25 and / or the short-side folding assembly 27. One end of the bottom side of the horizontal plate 261 is provided with a spacer pipe 262, which is correspondingly connected to the walking wheel 263, and the walking wheel 263 is also correspondingly connected to the walking motor 264. The other end of the bottom side of the horizontal plate 261 is provided with a fixed pipe 265, and the inner side of the fixed pipe 265 is correspondingly sleeved with a movable pipe 266, which is also correspondingly connected to the walking wheel 263. Both sides of the fixed pipe 265 and the movable pipe 266 are respectively connected to the inner and outer folding arms 267. The outer side of one of the inner and outer folding arms 267 is provided with a lifting motor 268, which is correspondingly connected to a sliding screw 269. The sliding screw 269 horizontally passes through the inner and outer folding arms 267. The present invention achieves precise adjustment of the inclination angle of the photovoltaic module and optimizes power generation efficiency. The lifting motor 268 in the walking device 26 drives the sliding screw 269 to push and pull the inner and outer folding arms 267 horizontally, changing the relative height of the fixed tube 265 and the movable tube 266, thereby adjusting the height difference on both sides of the cross plate 261 and adjusting the tilt of the bracket in real time; the second wheel group is actively anti-skid, and each walking wheel 263 is independently driven by the walking motor 264, so that the foldable multi-row support bracket can slide in and out of the container in the retracted state, and at the same time, the foldable multi-row support bracket can be driven horizontally to unfold, so that the bracket can dynamically adjust the inclination angle on the slope, solving the problems of low efficiency and poor slope adaptability of the existing technology of manual leveling, and ensuring that the solar panel is always facing the optimal light angle through real-time angle fine-tuning, thereby improving the energy conversion efficiency.

[0032] like Figure 8 and Figure 9 As shown, the energy storage container system 3 includes a box body 31 with a hollow cavity structure. The present invention is an energy storage device that is easy to move and install, usually including one or more container bodies 31, each of which is equipped with power components such as battery packs, battery management systems, inverters, cooling equipment, distribution systems, and control systems.

[0033] A charging device door 32 is provided at one end of the box 31, and a photovoltaic rack deployment door 33 is provided at the other end. The charging device door 32 and the photovoltaic rack deployment door 33 are arranged at a 90° angle, and in conjunction with a forklift port 36, the box 31 can be positioned on one side, facilitating transport of the energy storage container system 3. A debugging room 34 is provided within the box 31, equipped with a built-in voltage detection port and fault diagnosis module, allowing maintenance personnel to complete maintenance without entering the equipment area.

[0034] A photovoltaic bracket and a fire-fighting temperature control unit system (not shown in the figure) are also provided inside the box 31. The fire-fighting temperature control unit system includes a first switch unit, a second switch unit, a temperature regulating unit, a liquid pipeline, and a plurality of nozzles. The first switch unit is connected between the liquid pipeline and the temperature regulating unit, the second switch unit is connected between the liquid pipeline and the water storage device, the temperature regulating unit is arranged in the equipment cabin, and a plurality of water inlets and a plurality of water return ports are provided on the liquid pipeline. The plurality of water inlets and a plurality of water return ports on the liquid pipeline are respectively connected to the temperature regulating pipeline of the corresponding battery compartment. All nozzles are provided on the liquid pipeline and are connected to the liquid pipeline. The plurality of nozzles are respectively installed in the corresponding battery compartment. The fire-fighting temperature control unit system of the present invention realizes automatic temperature control and fire prevention through the design of the switch unit and the nozzle, solves the problem of low operation and maintenance efficiency of the existing technology, reduces manual intervention through the automated diagnosis and temperature control mechanism, and reduces long-term operating costs.

[0035] The side of the box 31 is provided with a plurality of ventilation openings 35, the bottom of the box 31 is provided with a forklift port 36, the top of the box 31 is provided with an exhaust system 37, the other side of the box 31 is provided with a ladder 38, and the top of the box 31 is provided with a plurality of upward-turning ventilation openings 39. The energy storage container system 3 of the present invention adopts a heat duct avoidance structure. The ventilation openings 35 are located away from the projection area of ​​the bracket storage, and the upward-turning ventilation openings 39 form a three-dimensional convection, which accelerates heat circulation and improves heat dissipation.

[0036] The exhaust system 37 includes a short exhaust pipe 371 and several long exhaust pipes 372. The short exhaust pipe 371 is shorter than the long exhaust pipe 372 and is positioned above the vent 35. The long exhaust pipes 372 are evenly distributed on the other side of the housing 31. The present invention employs a layered heat diversion design. The vents 35 on the side of the housing and the short exhaust pipes 371 on the top form a vertical air duct that directly covers the heat-generating area of ​​the battery pack. The distributed layout of the long exhaust pipes 372 enhances the overall heat dissipation efficiency of the housing.

[0037] The energy storage container system 3 of the present invention optimizes heat dissipation design, improving the system's operating efficiency and lifespan. Ventilation openings 35 of the energy storage container system avoid the projected area of ​​the bracket storage, and cooperate with upward-folding vents 39 to form three-dimensional convection. The exhaust system 37 utilizes layered heat diversion, with short exhaust pipes 371 covering the battery pack's heating area and long exhaust pipes 372 arranged in a distributed pattern to enhance overall heat dissipation. This solves the problem of insufficient heat dissipation caused by the fixed layout of existing energy storage containers. By avoiding air ducts and layered diversion, heat flow is accelerated, preventing equipment overheating and reducing the frequency and cost of operation and maintenance.

[0038] The power-consuming device load-side system includes several car or bicycle charging stations. The charging stations, which adjust output power by varying output power, function similarly to gas pumps at gas stations. They can be installed in containers, fixed to the ground or wall, or installed in public buildings (such as public buildings, shopping malls, and public parking lots), residential parking lots, or charging stations. They can charge various models of electric vehicles and bicycles at varying voltage levels.

[0039] In a specific embodiment, 1. transporting the energy storage container system 3 to a suitable site;

[0040] 2. The process of transferring the foldable multi-row support bracket from the placement location: When the present invention is in the bracket retracted state, the bottom walking device 26 walking motor 264 drives the walking wheel 263 to move, allowing the entire foldable multi-row folding bracket to slide out from the energy storage container system 3.

[0041] 3. The lateral expansion process of the foldable multi-arrangement support bracket: Using the coordinated processing of electrical signals, the walking motor 264 of the walking device 26 drives the walking wheel 263, and at the same time, the folding motor in the fixed component 25 and the power motor in the short side folding component 7 are driven to complete the angle expansion process, so that the foldable bracket unit 21 slowly expands during the horizontal movement. After completing the basic action, the motor is locked.

[0042] 4. The vertical unfolding process of the foldable multi-arrangement folding bracket: using the coordinated processing of electrical signals, the travel motor of the sliding assembly 241 in the long side folding assembly 24 drives the screw to rotate, and then drives the screw travel block to move along the sliding track in the main beam frame 22. At the same time, the motor in the folding arm is driven, and the folding arm completes the active folding arm action, driving one of the sub-beam frames 23 and the fixed connection part 242 in the long side folding assembly 24 to rotate, fold and unfold.

[0043] The vertical expansion process needs to be divided into a certain order. The first step: when the horizontal expansion state is started, the first layer of the sub-beam frame 23 is connected to the walking motor of the sliding component 241 in the long side folding component 24, driving the first layer of the sub-beam frame 23 and the fixed connection part 242 in the long side folding component 24 to rotate, fold and open, and wait for it to be folded into place, and then the action is locked and the next step is carried out; the second step: when the horizontal expansion state is started, the second layer of the sub-beam frame 23 is connected to the walking motor of the sliding component 241 and the motor in the folding arm, driving the second layer of the sub-beam frame 23 and the fixed connection part 242 to rotate, fold and open, and wait for it to be folded into place, and then the action is locked.

[0044] 5. Angle adjustment process of the foldable multi-arrangement folding bracket assembly: the lifting motor 268 in the walking device 26 drives the sliding screw 269 in the inner and outer folding arms 267 to rotate, and the inner and outer folding arms 267 are changed from an overlapping state to an angle-changing state, that is, the height between the fixed tube 265 and the movable tube 266 is changed, and the height difference between the plates on both sides of the horizontal plate 261 in the walking device 26 is changed, thereby achieving the purpose of changing the inclination angle of the photovoltaic module. After waiting for the adjustment to be in place, the action is locked.

[0045] 6. The present invention is installed in place and uses the load end system of the electrical equipment in the energy storage container system 3 to work externally.

[0046] This invention is a mobile charging station with integrated solar storage and charging, offering convenient loading and quick assembly and installation for emergency power supply. It can be used immediately after assembly and commissioning. In extremely severe weather, the foldable multi-row support brackets can be quickly folded and integrated into the energy storage container system 3, fully utilizing the available space.

[0047] This invention utilizes foldable, multi-arrange support brackets, offering convenient and adjustable operation, allowing for easy adjustment of component tilt based on site conditions and geographic location. The Energy Storage Container System 3 offers modular, categorized packages, enabling quick and easy matching of components, profiles, and accessories. This system offers greater convenience than traditional, customizable foldable energy storage container power generation systems, resulting in shorter product cycles and less labor.

[0048] The entire system of the present invention integrates photovoltaic storage and charging. The electricity generated by the solar panels is stored in the container battery pack, which directly powers the charging pile. The foldable storage of the bracket reduces resource waste, solves the problem of inconvenient disassembly of the traditional system, realizes convenient movement and reuse, reduces carbon emissions, and promotes the implementation of environmental protection concepts in emergency and daily scenarios.

[0049] Although the technical solutions of the present invention have been described and listed in detail, it should be understood that it is obvious to those skilled in the art to make modifications to the above embodiments or adopt equivalent alternatives. These modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
