[0027] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0028] This photovoltaic energy storage device primarily uses a mobile container-type photovoltaic unit, with improvements made to its mobility and convenience. Its main structure includes:

[0029] 1 container body

[0030] The container body is the main frame of the entire device. It usually adopts standard container size and features high strength, corrosion resistance and ease of transportation.

[0031] The container body adopts a rectangular structure, consistent with existing containers used as photovoltaic carriers. It can be equipped with a door at one end or a top panel structure that can be opened and closed.

[0032] Its internal space is divided into zones for arranging and installing equipment such as photovoltaic controllers, inverters, and energy storage batteries.

[0033] 2 mobile chassis

[0034] Fixedly installed at the bottom of the container body, specifically including a chassis with wheels mounted on both sides, the chassis can be fixed to the container body, making the entire device a mobile carrier that can be towed, rather than simply a standalone container hoisted onto a truck. This allows it to move at any time via towing or trailer, and it can also be self-supporting via its tires. It can adapt to poor ground conditions, eliminating the need for ground leveling, and can be used immediately upon arrival.

[0035] 3 Photovoltaic institutions

[0036] The photovoltaic (PV) mechanism is the core component, responsible for converting solar energy into electricity. While foldable and retractable PV mechanisms exist, they all require the container to be lifted and landed before unfolding. When the container is suspended in mid-air, it cannot be easily unfolded for use.

[0037] Furthermore, to facilitate the demonstration of this part of the structure, the attached diagram omits the container body, as well as the bottom of the container body and other internal equipment.

[0038] Therefore, the photovoltaic mechanism, as a core improvement, includes the following structure:

[0039] 3.1 Telescopic Photovoltaic Modules

[0040] The telescopic photovoltaic module includes multiple photovoltaic panels 1. The photovoltaic panels 1 have a frame 2 around their perimeter. The frame 2 is a rectangular frame structure. The bottom side of the frame 2 has two downwardly extending legs that are symmetrically arranged on the left and right sides. The bottom end of the legs is provided with casters 3 that are fixedly installed thereon.

[0041] The top of the side of the frame 2 is provided with an upper shaft 6, the middle of the side of the frame 2 is provided with a central shaft 7, and the bottom of the side of the frame 2 is provided with a lower shaft 8. The upper shaft 6, the central shaft 7 and the lower shaft 8 are all located on the back side of the absorption surface of the photovoltaic panel 1.

[0042] To achieve telescopic connection, adjacent photovoltaic modules are connected by a linkage assembly, which includes a long linkage 4 and two short linkages 5. The two short linkages 5 are used to hinge the adjacent photovoltaic panels 1 at the first and second ends, respectively. Specifically, the top end of one short linkage 5 is hinged to the central shaft 7 at the first end, and the bottom end of the short linkage 5 is hinged to the lower shaft 8 at the second photovoltaic panel 1. The top end of the other short linkage 5 is hinged to the upper shaft 6 of the adjacent photovoltaic panel 1 at the last end, and the bottom end of the short linkage 5 is hinged to the central shaft 7 of the photovoltaic panel 1 at the last end. The long connecting rod 4 is twice the length of the short connecting rod 5. The middle part of the long connecting rod 4 is hinged to the central shaft 7 of an intermediate photovoltaic panel 1, the top end of the long connecting rod 4 is hinged to the upper shaft 6 of the adjacent photovoltaic panel 1, and the bottom end of the long connecting rod 4 is hinged to the lower shaft 8 of the adjacent photovoltaic panel 1, thus forming a scissor-type telescopic structure. The photovoltaic panels 1 can be extended by pulling to facilitate the capture of light energy, or they can be folded into a vertical bundle for easy transportation and movement.

[0043] A post 9 can also be hinged to the central axis of the photovoltaic panel 1 at the tail end. The bottom end of the post 9 is a pointed tip, which facilitates support for the photovoltaic panel 1 at the tail end after it is unfolded.

[0044] 3.2 The lifting frame 10 is fixed to the top of the container body. The length of the lifting frame 10 is consistent with the length of the container body. Ideally, the lifting frame 10 should be centered relative to the width of the container body, with one end positioned near the container door for easy extension and lowering of the photovoltaic equipment. The lifting frame 10 can be constructed from channel steel or square steel welded into an I-beam or U-shaped frame structure, and fixed to the container body using bolts or other fasteners.

[0045] 3.3 Suspension Rail 11

[0046] Two hanging rails 11 are symmetrically and side by side fixedly installed below the hoisting frame 10.

[0047] A slider 12 is slidably fitted on the hanging rail 11, and the length direction of the hanging rail 11 is set in the same direction as the lifting frame 10.

[0048] 3.4 Carriage

[0049] The carriage adopts a long rectangular frame structure, and the length direction of the carriage is consistent with the hanging rail 11.

[0050] The carriage includes two side beams 13 arranged side by side. The side beams 13 have a front beam 14 connecting the two at the end near the door and a rear beam 16 connecting the two at the end away from the door.

[0051] The slider 12 is fixed to the top of the side beam 13, and the slider 12 is arranged away from the door, which facilitates the carriage to extend out of the door.

[0052] The front beam 14 is provided with a front transverse shaft 15, and the rear beam 16 is provided with a rear transverse shaft 17. The front beam 14, the front transverse shaft 15, the rear beam 16, and the rear transverse shaft 17 all extend side by side relative to the width direction of the container body.

[0053] 3.5 Translational Cylinder Block

[0054] It can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. Its tail end is fixed on the lifting frame 10. The end of the translation cylinder near the box door is provided with a translation cylinder rod 18 that is telescopically coordinated with it. The front end of the translation lever is connected to the front horizontal shaft 15. Based on the drive of the translation cylinder, the translation and position of the slide can be controlled, thereby realizing the adjustment of the distance relative to the box door.

[0055] 3.6 Landing Gear

[0056] It includes a strip frame 19 arranged parallel to the hanging rail 11, and the end of the strip frame 19 near the door is provided with a hinged beam 21 that connects the two.

[0057] Each side of the strip frame 19 has two swing rods 20 hinged to its top. The top of each swing rod 20 is hinged to the side beam 13 on the same side. The two swing rods 20 on the same side are arranged in parallel. Based on the swing of the swing rods 20, the landing gear can move closer to or separate from the carriage, thereby achieving the lifting and lowering effect.

[0058] Below the strip frame 19, there is a bracket that is fixed to it. The length direction of the brackets on both sides is the same as that of the hanging rail 11. The bracket includes a strip plate 22 that is parallel to the hanging rail 11 and is erected vertically. Both ends of the strip plate 22 are fixed with baffles 23 that are perpendicular to it. The distance between the strip plates 22 on both sides is greater than the length of the upper shaft 6. The bottom side of the baffle 23 is provided with a strip hole 25 that is adapted to its length. A support plate 24 is slidably fitted through the strip hole 25. The outer end of the support plate 24 is provided with a pin tube 26, and a pin rod 27 passes through the pin tube 26. The pin 27 has a handle at its top end, and the bottom side of the baffle 23 has an outwardly extending pin seat 28 in the center. The pin seat 28 has a pin hole that mates with the pin 27. The pin 27 passes through the pin tube 26 and the pin seat 28, which can fix the support plate 24. When the support plate 24 is fixed on the bracket, the distance between adjacent sides of the two support plates 24 is less than the length of the upper shaft 6 and greater than the width of the photovoltaic panel 1. This allows the upper shaft 6 of the folded photovoltaic panel 1 to be lifted and lowered to the ground, overcoming the height of the wheels to achieve automatic hoisting. It can also retract the used photovoltaic modules.

[0059] 3.7 Lifting Cylinder

[0060] The tail end of the lifting cylinder is hinged to the rear transverse shaft 17 of the slide. The front end of the lifting cylinder near the door is provided with a lifting cylinder rod 29 that is telescopically coordinated with it. The end of the lifting cylinder rod 29 is hinged to the hinge beam 21, thereby realizing the driving and control of the lifting and lowering of the landing gear and its height based on the lifting cylinder.

[0061] 4 Photovoltaic power generation control unit

[0062] The control unit is the "brain" of the system, responsible for managing and controlling the entire photovoltaic power generation process. Commonly available control devices can be used, typically including:

[0063] 4.1 Controller: Used to monitor and regulate the output power of photovoltaic modules to ensure stable system operation.

[0064] 4.2 Inverter: Converts the direct current generated by the photovoltaic modules into alternating current for use by AC loads.

[0065] 4.3 Energy storage battery: Used to store electrical energy to provide stable power to the load.

[0066] 5 auxiliary systems

[0067] The container is equipped with ventilation to ensure the equipment maintains a suitable temperature during operation. Monitoring equipment can also be added, including visual monitoring, temperature monitoring, and humidity monitoring, to provide real-time monitoring of the operation.

[0068] Based on our aforementioned structure, this energy storage device, combined with containerized energy storage, achieves self-propelled movement via its own chassis. It can be flexibly moved by being towed by other vehicles. Upon arrival at the site, it requires no hoisting, relying directly on the chassis for support. It has low ground requirements and adapts to various complex environments. Further improvements could be made by adding a drive system to the chassis, enabling self-driving and autonomous movement, further enhancing its flexibility and autonomy.

[0069] During photovoltaic conversion operations, the sliding carriage is first pushed towards the container door, positioning it near the door at the outer end. Then, the landing gear lowers the photovoltaic mechanism to the ground. Manual assistance is used for unloading and unfolding, allowing for operation. To retract, the photovoltaic mechanism is manually attached to the side brackets and then retracted into the container using the landing gear. The entire operation requires no additional lifting equipment. By using a detachable and separable photovoltaic mechanism and mechanical lifting and retraction operations, the container body and vehicle body do not need to be separated; the entire container body does not need to be lowered to the ground. Operation is carried out using the independent photovoltaic mechanism.

[0070] Existing containerized photovoltaic (PV) equipment mainly employs three methods for deploying PV modules: top deployment, side deployment, and bottom deployment. Top and side deployments require reliable support structures, resulting in high costs. Bottom deployments require the container bottom to be close to the ground, and the deployment structure includes common telescopic and folding structures such as scissor frames. Ground-based auxiliary supports can reduce costs associated with telescopic supports. However, bottom deployment structures rely on the container being grounded. This device, through its automatic PV deployment and retraction mechanism, eliminates the need for the container to be grounded, supporting the fixing of the container to the vehicle chassis, thus achieving convenient and flexible movement.
