Description

Technical Field

[0001] This application relates to the field of solar photovoltaic power generation technology, and in particular to a photovoltaic power generation energy storage device suitable for complex scenarios. Background Technology

[0002] In complex scenarios such as mountain operations, field exploration, emergency rescue and disaster relief, and military operations, there are frequent temporary or emergency power supply needs. These scenarios are typically characterized by rugged terrain, harsh environmental conditions, inconvenient transportation, and limited deployment time windows, which place extremely high demands on the portability, rapid deployment capability, environmental adaptability, and independent operational reliability of power supply equipment.

[0003] Currently, common power supply solutions mainly fall into two categories, but both have significant limitations: Traditional fixed photovoltaic (PV) power generation systems rely on large, flat sites for installing PV arrays and require complex civil engineering work such as piling, foundation pouring, and installation of mounting brackets. Their components include PV panels, inverters, energy storage batteries, and cables, which are dispersed, making the system bulky and immobile. Therefore, they are completely unsuitable for complex terrain scenarios with uneven ground requiring rapid relocation, resulting in high infrastructure costs and long construction periods.

[0004] 1. Existing mobile photovoltaic devices: To improve flexibility, some mobile photovoltaic devices have emerged on the market, but they still have significant shortcomings in practical applications, mainly in two aspects: 2. Poor terrain adaptability and deployment stability: Many mobile devices are only equipped with simple brackets or wheeled bases, lacking a dedicated structure for actively adapting to uneven ground. They are difficult to level and fix quickly and stably on complex terrains such as slopes, gravel, and soft ground, making them prone to tipping over or causing a significant reduction in power generation efficiency due to poor angles.

[0005] 3. Low system integration and cumbersome deployment process: Most devices adopt a design that separates the power generation module and the energy storage unit. During use, they need to be transported separately, physically connected on-site, and electrically wired. This process is time-consuming and labor-intensive, and the numerous connection points increase reliability risks. This makes them unable to meet the requirements for rapid emergency response upon arrival, putting them at a significant disadvantage in time-sensitive rescue or exploration missions.

[0006] In summary, existing technologies face challenges in complex environments such as mountainous and wilderness areas, balancing portability and power generation capacity, rapid deployment and structural stability, and integrated design and safety. Therefore, there is an urgent need for an innovative photovoltaic power generation and storage device. This device must highly integrate power generation and storage units, possess deployment and stable support mechanisms adaptable to complex terrain, and enable rapid, automated, or semi-automated deployment from transport to operational status. This would provide users with a convenient, reliable, and efficient complete power supply solution in complex environments. Summary of the Invention

[0007] To address the aforementioned issues, this application provides a photovoltaic power generation and energy storage device suitable for complex scenarios.

[0008] A photovoltaic power generation and energy storage device suitable for complex scenarios includes a main frame, at least one rotatable folding frame mounted on the side of the main frame, at least one extension frame hinged to the folding frame, and photovoltaic panel arrays fixed to the folding frame and the extension frame. The main frame serves as an integrated base, housing equipment such as a power supply box; the folding frame and the extension frame form a multi-stage unfolding mechanism, which can quickly unfold from a compact transport state into a large-area light-receiving working surface; the photovoltaic panel arrays unfold synchronously with the frame, enabling rapid deployment of the power generation array.

[0009] The aforementioned technical solution achieves a high degree of integration of power generation, energy storage, transportation, and deployment mechanisms. In complex scenarios, it can quickly transform from a regular cubic transportation form into a stable large-area power generation form without on-site assembly and wiring, which is beneficial for improving deployment speed, terrain adaptability, and ease of operation.

[0010] Furthermore, the number of folding frames is four, which are respectively arranged on the front, rear, left and right sides of the main frame.

[0011] The four folding frames unfold in tandem, simultaneously expanding the light-receiving area from all sides of the device to form a multi-directional light-collecting array. This helps improve space utilization and power generation per unit area, while maintaining balance and structural symmetry during the unfolding process.

[0012] Furthermore, the photovoltaic panel assembly includes multiple photovoltaic panels, which are respectively disposed on the top of the main frame, the four folding frames, and the extension frame.

[0013] This arrangement achieves full coverage of photovoltaic panels on the top of the main frame, all sides, and secondary extension surfaces. When fully deployed, it can make full use of sunlight from the top and sides, creating three-dimensional lighting and helping to improve the overall photoelectric conversion efficiency under different time periods and lighting conditions.

[0014] Furthermore, the main frame is configured as a cubic frame structure.

[0015] The cube-shaped frame structure has good symmetry and consistent dimensions in all directions, which makes the folded device neat and compact, easy to stack, transport and store, and suitable for scenarios with strict restrictions on transportation space.

[0016] Furthermore, the main frame is configured as a cuboid frame structure.

[0017] The cuboid frame allows for flexible adjustment of its length, width, and height ratios to suit the size of the actual transport vehicle or specific layout requirements, thus improving the device's adaptability to different transport conditions and application scenarios.

[0018] Furthermore, when the main frame is a cuboid frame structure, the extension frame is mounted on the folding frames on the two relatively large opposite sides of the main frame.

[0019] In a cuboid configuration, the extension frame is preferentially deployed on the side with a larger area. This maximizes the use of the space on the main unfolding surface to add photovoltaic panels without significantly increasing structural complexity, which is conducive to achieving a balance between structural efficiency and power generation capacity.

[0020] Furthermore, it also includes connectors, which are plates with one end hinged to the frame of the main frame and the other end hinged to the folding frame; a single folding frame is connected by multiple connectors.

[0021] Multiple connecting parts form a stable multi-link flipping mechanism, which can effectively constrain the movement trajectory of the folding frame during the unfolding process, prevent it from swaying, shaking or twisting, and ensure the accuracy of the unfolding posture and the rigidity of the overall structure.

[0022] Furthermore, the plurality of the connectors are arranged at intervals along the width direction of the folding frame.

[0023] The connectors are evenly distributed along the width direction, which can evenly transfer the unfolded load to the main frame, making the folding frame more evenly stressed. This helps to enhance the stability of the unfolding process and the torsional and wind resistance of the structure in the unfolded state.

[0024] Furthermore, it also includes a support mechanism, which includes a pneumatic strut, with both ends of the pneumatic strut fixedly installed on the main frame and the folding frame, respectively.

[0025] The pneumatic strut stores energy when folded and releases it when unfolded to provide a boost, making the unfolding operation of the folding frame more effortless, stable and controllable, and reducing the intensity of manual operation.

[0026] Furthermore, it also includes a drive mechanism, which includes a hydraulically driven push rod for driving the folding frame to unfold or fold.

[0027] The hydraulically driven push rod provides active, powerful, and controllable driving force, enabling automated or semi-automated operation of the folding frame's unfolding and retraction. This helps shorten state transition time, improve deployment speed and consistency, and is suitable for emergency scenarios requiring rapid response.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the main frame, folding and unfolding mechanism, photovoltaic panels and power supply box into one unit, a rapid transition from transportation to power generation is achieved. No complicated assembly and wiring are required on site, meeting the need for ready-to-use in complex scenarios.

[0029] 2. The multi-stage deployment design, combined with pneumatic assistance and rigid support rod locking, allows the device to be flexibly deployed to obtain a large lighting area, and can quickly establish a stable power generation platform on uneven terrain such as slopes and gravel ground, ensuring power generation efficiency and equipment safety.

[0030] 3. The optional hydraulic drive mechanism automates the core deployment action, while the pneumatic support rod provides labor-saving assistance. In addition, the integrated electronic control and energy storage management reduces the physical and technical barriers for operators, enabling the equipment to be used efficiently in various environments.

Thus, a feature defined as first or second may explicitly or implicitly include one or more of that feature. In the description of this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0035] In this invention, unless otherwise explicitly specified and limited, the terms installation, connection, linking, fixing, etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] The following is in conjunction with the appendix Figure 1-3 The specific implementation methods of this application are described in detail. The photovoltaic power generation and energy storage device in this embodiment is designed for complex terrain scenarios such as mountains and field exploration, and integrates power generation, energy storage, transportation protection and rapid deployment.

[0037] This device includes a main frame 1. The main frame 1, serving as the load-bearing and integrated base for the entire device, is designed as a cubic frame structure. This frame not only provides installation space for the internal equipment but also provides a supporting foundation for the external unfolding structure. The main frame 1 can adopt a cubic frame structure or a cuboid frame structure. In the cubic configuration, all faces have consistent dimensions, resulting in a symmetrical structure that facilitates neat storage after folding. In the cuboid configuration, the length, width, and height ratio can be adjusted according to transportation space or photovoltaic panel layout requirements, enhancing adaptability to different scenarios.

[0038] The main unit frame 1 houses the power supply box. The frame structure ensures overall strength while reducing weight, facilitating handling. The cubic shape is regular when fully folded, making it easy to stack and transport, and the frame itself provides mechanical protection for the internal equipment.

[0039] A folding frame 11 is installed on at least one side of the main frame 1. In this embodiment, it is preferable to provide one folding frame 11 on each of the four sides of the main frame 1 other than the bottom and top surfaces, that is, one in each of the four directions: front, back, left, and right.

[0040] Each folding frame 11 is rotatably connected to the frame of the main frame 1 via a rotating component, enabling it to unfold outwards or fold inwards. The rotating component can be, for example, a hinge or a pivot. The folding frame 11 itself is also a frame structure that matches the side shape of the main frame 1.

[0041] To ensure the stability of the folding frame 11 during unfolding, a connector 13 is provided. The connector 13 is a plate, one end of which is hinged to the frame of the main frame 1, and the other end is hinged to the folding frame 11. Each folding frame 11 is typically connected by multiple connectors 13, which are equidistantly distributed along the width direction of the folding frame 11 to form a stable multi-link flipping mechanism, preventing tilting or swaying during unfolding.

[0042] The folding frame 11 is one of the main supporting platforms for the photovoltaic panels, and its unfolding significantly increases the light-receiving area. Multiple folding frames 11 unfold collaboratively, allowing the device to quickly transform from a compact transport state to a large-area power generation state. To further expand the light-receiving area, extension frames 12 are also provided on the folding frame 11. The extension frames 12 are square frame structures, mounted on the vertical bars of the folding frame 11 via hinges 14. Two extension frames 12 can be symmetrically installed on each folding frame 11, hinged to the left and right vertical bars respectively. The extension frames 12 can be folded towards the folding frame 11, forming a multi-layered stacked structure. When the main frame 1 is a cuboid, the extension frames 12 are preferably installed on the two larger, opposite sides of the folding frame 11 to balance the structure and maximize space utilization. After all extension frames 12 and folding frames 11 are fully folded, the entire device returns to the shape of the main frame 1, with no protruding parts, facilitating transportation and storage. As a secondary deployment unit, the extension frame 12 further expands the installation area of ​​photovoltaic panels without significantly increasing the transportation volume, thereby improving the power generation capacity per unit area.

[0043] The photovoltaic panel array comprises multiple photovoltaic panels, namely a top panel 55, side panels, and a folding panel 56. The side panels include a front panel 51, a rear panel 52, a left side panel 53, and a right side panel 54, each fixed to its corresponding folding frame 11; the folding panel 56 is mounted on an extension frame 12. The photovoltaic panels are fixedly connected to the supporting frame and unfold as the frame unfolds, eliminating the need for secondary on-site installation or wiring. The panels are connected via pre-laid cables, forming a unified power generation circuit. Once unfolded, it forms a multi-directional, large-area light-collecting array, which helps improve photoelectric conversion efficiency; integrated wiring reduces on-site assembly time and increases deployment speed.

[0044] The support mechanism is used to stabilize the overall structure after deployment and to adapt to uneven ground. It includes pneumatic struts 42 and support rods 41. There are multiple pneumatic struts 42, with both ends fixed to the main frame 1 and the folding frame 11, respectively.

[0045] When folded, the gas inside the pneumatic support rod 42 is compressed, storing energy; when unfolded, the gas expands, providing a boosting force and reducing the external force required for unfolding, making the unfolding process smoother and less strenuous. Snap-fit ​​holes are provided at preset positions on the main frame 1, folding frame 11, and extension frame 12. After unfolding, the support rod 41 can be manually inserted to form a rigid triangular support or multi-point fixation, significantly enhancing overall wind resistance and terrain adaptability. The pneumatic support rod 42 provides assisted unfolding, while the support rod 41 provides rigid locking; the combination of these two ensures that the device maintains a stable power generation posture even in complex terrain.

[0046] The drive mechanism is used to automatically unfold and fold the folding frame 11. It includes a hydraulically driven push rod 3, which is driven by a hydraulic press and can be used singly or in multiples. One end of the hydraulically driven push rod 3 is mounted on the main frame 1, and the other end is connected to the folding frame 11. The extension and retraction of the push rod is controlled by a hydraulic system, pushing the folding frame 11 to rotate around the hinge point, achieving smooth and controllable unfolding and retraction. Using a drive mechanism to replace manual unfolding reduces operational intensity, improves deployment speed and consistency, and is suitable for rapid response in emergency scenarios.

[0047] The power supply box is installed inside the main frame 1 to store the electrical energy generated by the photovoltaic panels; it supplies power to the hydraulic press, control module, and other components in the drive mechanism; and it integrates the control system to achieve integrated management of power generation, energy storage, and power distribution. This design achieves compact integration of power generation and energy storage, eliminating the need for moving and wiring external energy storage devices, and enabling immediate deployment and use.

[0048] The implementation principle of this application is as follows: Transportation status: All folding frames 11 are folded inward, and the extension frame 12 is further folded into the folding frame 11, forming a compact cube. The power supply box is built-in, and the photovoltaic panels are protected by the frame, making it suitable for transportation.

[0049] Deployment process: The hydraulically driven top rod 3 pushes the folding frame 11 outward, and the pneumatic support rod 42 assists and provides cushioning; after the folding frame 11 is in place, the extension frame 12 can be deployed manually or with assistance; insert the support rod 41 to lock the deployment posture.

[0050] Power generation status: The photovoltaic panels generate electricity by receiving sunlight, and the electrical energy is stored in the power supply box, which can directly power the load or be stored as backup.

[0051] Retraction process: Pull out the support rod 41, the drive mechanism retracts the folding frame 11, the extension frame 12 folds accordingly, and finally returns to the transport form.

[0052] Using the main frame 1 as the integrated base, the folding frame 11 and the extension frame 12 form a multi-stage unfolding mechanism, which can be quickly and smoothly unfolded under the cooperation of the drive mechanism and the pneumatic support rod 42. After unfolding, the posture is locked by the support rod 41 to adapt to complex terrain. The photovoltaic panels form a power generation array as the frame unfolds, and the power box realizes the integration of power storage and supply, thus realizing the integrated functions of rapid deployment, stable power generation and convenient power storage and supply in complex scenarios.

[0053] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0054] The detailed descriptions listed above are merely specific illustrations of feasible embodiments of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
