Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and more specifically to a mobile, foldable photovoltaic system. Background Technology

[0002] With the continuous development of renewable energy technologies, photovoltaic power generation systems, as an important component, have been widely promoted in various application scenarios. However, existing photovoltaic power generation systems or photovoltaic power plants are typically characterized by being immobile and non-recyclable. Their deployment often relies on fixed support structures, frequently requiring the construction of new concrete foundations or steel structure systems, or attachment to existing buildings. These systems not only have long construction cycles, large on-site workloads, high energy consumption, and are detrimental to environmental protection, but also are difficult to relocate once built, failing to meet the highly mobile electricity demands of field operations, temporary projects, and other similar needs.

[0003] While there are already products such as balcony photovoltaics and solar folding bags for portable photovoltaic devices, these devices have relatively low power output and are only suitable for small-scale individual power generation needs. They are not suitable for medium to large-scale temporary power consumption scenarios that require frequent relocation and lack grid coverage, such as farm operations, mining, oil field development, and engineering project sites.

[0004] Currently, some portable photovoltaic (PV) systems on the market use a hinged structure, employing tracks and an electrical system to fold and store the PV modules. In practical applications, this type of structure requires tracks to be laid from the bottom to support the system's weight, resulting in a complex structure, high manufacturing and maintenance costs, and limited system stability, making it prone to damage. Furthermore, these tracks are typically close to the ground, making them unsuitable for complex terrain, especially in areas with dense vegetation, where shading can easily trigger hot spot effects, impacting system efficiency and module lifespan. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a mobile foldable photovoltaic system, including: a storage unit 1, a guide rail bracket assembly 3, and a photovoltaic module 2; a track hanger 11 is provided inside the storage unit 1, and a first track 12 is provided at the lower part of the track hanger 11; the guide rail bracket assembly 3 is adapted to be mounted on the outside of the storage unit 1, and the guide rail bracket assembly 3 includes a second track 34, which is adapted to be connected to the first track 12; the photovoltaic module 2 includes a plurality of photovoltaic frame structures 21 and roller assemblies 22 provided on the photovoltaic frame structures 21, the photovoltaic frame structures 21 are adapted to install photovoltaic panels, and the photovoltaic frame structures 21 rotate and roll in cooperation with the first track 12 and / or the second track 34 through the roller assemblies 22, and the photovoltaic frame structures 21 can slide along the length extension direction of the first track 12 and / or the second track 34 and fold or unfold during the sliding process.

[0022] Specifically, by setting a roller assembly 22 in the middle of the photovoltaic frame structure 21 and having it slide in conjunction with the first track 12 in the storage unit 1 and the second track 34 in the external guide rail bracket assembly 3, the linear movement and folding / unfolding linkage of the module are realized. By setting the guide rail bracket assembly 3 and the track hanger 11, the first track 12 and the second track 34 are provided with installation support, while the first track 12 and the second track 34 are made higher than the ground vegetation and obstacles, effectively avoiding problems such as weed obstruction and water erosion, reducing the impact of hot spot effect on the performance of photovoltaic modules, and improving the operating efficiency and service life of the system.

[0023] Understandably, the height of the guide rail bracket assembly 3 and the rail hanger 11 is adjustable, thereby allowing the installation height of the first rail 12 and the second rail 34 to be adjusted according to the applicable environment, thus improving the versatility of the system.

[0024] Reference Figure 6 As shown, in some embodiments of the present invention, the photovoltaic module 2 further includes a hinge component 23, and adjacent photovoltaic frame structures 21 are hinged to each other through the hinge component 23 to achieve linkage rotation and folding when the photovoltaic frame structure 21 slides along the track.

[0025] Specifically, the hinge component 23 enables the photovoltaic frame structure 21 to rotate and move together. When one photovoltaic frame slides along the track, it drives the adjacent photovoltaic frames to unfold or fold synchronously, avoiding the tedious steps of operating each component independently. After the hinge component 23 connects multiple photovoltaic frames, it forms a chain structure. During unfolding or folding, it can maintain the relative positional relationship between the components, avoiding problems such as misalignment and jamming caused by inconsistent sliding. This greatly improves the efficiency of system deployment and folding, while also improving the structural coordination and stability of the system during operation.

[0026] In some embodiments of the present invention, the hinge assembly 23 includes a hinge, a hinge lug, and a pin passing through the hinge and the hinge lug to form a rotational connection between adjacent photovoltaic frame structures 21.

[0027] Specifically, the hinge and hinge ear plate are connected by pins to achieve an efficient and stable rotational connection, allowing adjacent photovoltaic frames to rotate and fold smoothly during sliding. This ensures a fast and accurate linkage response of the system and effectively improves the mechanical linkage performance of the system. The hinge structure adopts a pin connection method, which has good disassembly and facilitates quick assembly and disassembly on site, meeting the actual needs of the system for rapid deployment, convenient transportation and reuse.

[0028] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the mobile foldable photovoltaic system further includes a connection component 4, which is adapted to connect the first track 12 and the second track 34, or two adjacent second tracks 34, so that the roller assembly 22 slides between the first track 12 and the second track 34.

[0029] Specifically, the connecting component 4 enables precise alignment between the first track 12 within the storage unit 1 and the second track 34 on the guide rail bracket assembly 3, creating a continuous sliding path. This allows the photovoltaic frame structure 21 to smoothly transition and slide during unfolding or folding, preventing jamming or derailment. It is understood that the connecting component 4 allows for adjustments to the height, angle, and alignment between the tracks, eliminating track alignment deviations caused by transportation, terrain, or installation errors. This ensures smooth and reliable sliding of the roller assembly 22, guaranteeing the mechanical stability of the entire photovoltaic system.

[0030] The fast connection between track segments is achieved through the connecting component 4, which enables the entire photovoltaic track system to be flexibly spliced ​​and expanded according to power generation needs or site conditions, thereby improving the system's adaptability and flexible configuration capabilities and meeting the needs of diverse application scenarios.

[0031] In some embodiments of the present invention, the roller assembly 22 is disposed in the middle of the photovoltaic frame structure 21, and the rotating shaft of the roller assembly 22 is located in the middle position of the corresponding photovoltaic frame structure 21.

[0032] Specifically, the roller assembly 22 adopts a central design, which enables the photovoltaic frame structure 21 to achieve balanced rotation with its center of gravity as the fulcrum during sliding. This effectively reduces the problem of overturning or tilting caused by off-center loading, and improves the stability and smoothness during folding and unfolding. Compared with the traditional off-center roller design, the central arrangement significantly reduces the torque resistance during rotation, making the photovoltaic module 2 lighter and smoother during linkage folding, and improving the response sensitivity and overall efficiency when multiple photovoltaic frame structures 21 are folded synchronously.

[0033] Reference Figure 7 As shown, in some embodiments of the present invention, the first track 12 and the second track 34 are both C-shaped steel structures, the second track 34 is an irregular C-shaped steel track, and the opening of the second track 34 is offset outward.

[0034] Specifically, by designing both the first track 12 and the second track 34 as C-shaped steel structures, and by making the second track 34 an irregularly shaped C-shaped steel with an outwardly offset opening, the lateral tolerance space of the rollers during the sliding process is effectively expanded, avoiding interference or jamming of the rollers when running inside the track due to the narrow track opening, thereby improving the sliding efficiency and stability of the photovoltaic frame on the track.

[0035] In some embodiments of the present invention, the guide rail bracket assembly 3 includes a column 32, a foot support 31 and a transverse connecting beam 33. The column 32 passes through the foot support 31, the transverse connecting beam 33 connects two adjacent foot supports 31, and the second rail 34 is installed on the column 32.

[0036] Specifically, the foot support 31 provides basic support for the column 32, while the transverse connecting beam 33 effectively connects adjacent foot support 31 components, forming a three-dimensional stable frame structure. This significantly enhances the lateral force and deformation resistance of the entire track support system, ensuring stable operation even under the weight of photovoltaic modules and wind loads. The second track 34 is installed on the column 32, and the connection strength is enhanced by installing stiffening plates and other structures, ensuring the stability of the rollers running on the track. At the same time, it facilitates the connection between multiple track sections, enabling flexible splicing of system units to adapt to the power generation needs of different scales and layouts.

[0037] In some embodiments of the present invention, the foot support 31 and the column 32 are plug-in assembly structures. The foot support 31 is provided with a plurality of adjustment holes along the height direction. Positioning is achieved by inserting pins through the adjustment holes at different heights, so as to be suitable for the height and horizontal adjustment of the guide rail bracket assembly 3.

[0038] Specifically, by designing the foot support 31 and the column 32 as a plug-in assembly structure, and setting multiple height adjustment holes on the foot support 31, combined with the pin positioning method, the height and level of the guide rail bracket assembly 3 can be adjusted. The multiple adjustment holes and the pins cooperate to form a segmented height adjustment structure, which allows the guide rail bracket to be finely adjusted according to the actual ground height difference, adapting to the installation needs of uneven sites such as hills, slopes, and gravel ground, and ensuring that the entire track is in an ideal working height and level state.

[0039] Understandably, the pin-type connection not only has good adjustability, but also has high shear strength and mechanical stability. During long-term operation of the system, it can effectively resist external forces such as wind load and component sliding load, ensuring the safe operation of the overall structure.

[0040] Reference Figure 5 As shown, in some embodiments of the present invention, the movable foldable photovoltaic system further includes a rotation-limiting fixing kit 5, which is disposed on the first track 12 and / or the second track 34 to limit the rotation or sliding of the photovoltaic frame structure 21 caused by external forces.

[0041] Specifically, in the field or open environment, photovoltaic modules are susceptible to sudden strong wind impacts. By setting rotation-limiting fixing kits 5 on the first track 12 and / or the second track 34, the photovoltaic frame structure 21 is fixed and its rotation or sliding caused by external forces is suppressed. After the system is deployed, the rotation-limiting fixing kits 5 are used to lock the current position of the photovoltaic frame, which can effectively prevent structural shaking, tilting or misalignment caused by wind load, vibration or other external disturbances, and ensure that the photovoltaic modules operate stably at the set angle and position.

[0042] In some embodiments of the present invention, the storage unit 1 is a container or warehouse space.

[0043] Specifically, the container itself has good sealing and transportation adaptability, which allows the entire photovoltaic system to be transported as an independent unit in the stored state. It is suitable for field operations, areas with insufficient grid coverage, or temporary project sites. During non-power generation periods, such as at night or when it is not in use, the photovoltaic system can be folded and stored back in the container or warehouse, occupying a very small area, effectively freeing up site space and improving the comprehensive utilization rate of land resources.

[0044] Understandably, containers or warehouses, as enclosed spaces, can provide physical protection for photovoltaic systems during transportation and storage, reducing damage to photovoltaic modules and mechanical structures from natural environmental factors such as rain, snow, dust, and ultraviolet radiation, thereby lowering the failure rate and extending service life.
