Description

Technical Field

[0001] The utility model belongs to the technical field of solar photovoltaic components, and in particular relates to a foldable and storable photovoltaic component array. Background Art

[0002] Solar cell module refers to the smallest indivisible solar cell assembly device with external packaging and internal connections that can independently provide DC output. In recent years, photovoltaic modules have developed in the direction of distributed applications and building integrated photovoltaics (BIPV), and can be installed in building doors and windows, curtain walls and roofs.

[0003] When photovoltaic modules are applied to doors, windows and curtain walls of buildings, factors such as light transmission, aesthetics, installation convenience and service life need to be considered. At present, the mainstream design chooses to integrate photovoltaic modules with doors, windows and curtain wall structures as much as possible to improve the weather resistance and installation convenience of photovoltaic modules, but it is impossible to independently choose light transmission or flexibly store them according to actual conditions, which further limits the promotion and application of photovoltaic modules in the field of construction.

[0004] When installing traditional photovoltaic modules, each module needs to be transported to the site and fixed on the ground with brackets, which not only consumes a lot of time and energy, but also is difficult to apply to building doors, windows, curtain walls and other scenes. When photovoltaic modules are integrated with doors, windows and curtain walls, it is difficult to adjust the angle, resulting in insufficient photovoltaic utilization and low power generation efficiency; it is also impossible to flexibly store or adjust indoor light transmittance according to actual conditions, which limits the promotion and application of photovoltaic modules in the field of construction.

[0005] Chinese patent application CN117439521A provides a structure of a foldable photovoltaic module array, in which the upper and lower ends of the photovoltaic panel assembly are hinged to each other in sequence, and the assembly is moved on the guide rail on the ground by rollers, so that the photovoltaic module body can be unfolded and folded. When the photovoltaic module body is unfolded, the limit pull rope is tightened, the photovoltaic module body is wavy, and the upper end is fixed to the ground by a windproof rope. The photovoltaic module body is foldable, and it is convenient to carry when folded. However, each time the assembly is unfolded and folded, the windproof rope needs to be repeatedly fixed or untied, and the manual operation is cumbersome; the designed photovoltaic module has a fixed angle, and the light utilization rate is low, which affects the efficiency of the photovoltaic module; compared with traditional steel photovoltaic module brackets, the weather resistance and practicality of the windproof rope and roller are poor, and they are easily damaged in extreme weather and cause losses. Utility Model Content

[0006] The technical problem to be solved by the utility model is to solve the problems of existing photovoltaic components, such as difficulty in fixing, poor weather resistance, and cumbersome manual operation when unfolding or folding, and to provide a foldable and storable photovoltaic component array with compact structure, convenient disassembly and assembly, high reliability, high adjustment flexibility and low cost.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A foldable photovoltaic module array comprises: a support frame, a photovoltaic panel assembly and a buckle; the support frame adopts a rectangular frame structure, and support columns are symmetrically arranged on both sides of the support frame; a plurality of photovoltaic panel assemblies are arranged on the inner side of the support frame to form a photovoltaic module array, and adjacent photovoltaic panel assemblies are hinged by hinges, and both ends of a single photovoltaic panel assembly are connected to the support column by buckles, and when the buckle is turned, the photovoltaic panel assembly is driven to move back and forth along the support column, thereby realizing the folding or unfolding of the photovoltaic module array.

[0009] As a further improvement of the present invention, a storage box is provided on the side of the support frame, and the storage box is used to accommodate the folded photovoltaic component array.

[0010] As a further improvement of the utility model, a plurality of connection holes are evenly distributed on the support column. When the photovoltaic module array is unfolded to a preset angle inside the support frame, the buckles on both sides of the photovoltaic panel assembly are connected and fixed to the connection holes to fix the photovoltaic module array.

[0011] As a further improvement of the present invention, bolt assemblies are provided on the buckles located at the head and end of the photovoltaic module array. When the photovoltaic module array is unfolded to a preset angle on the inner side of the support frame, the buckles are connected and fixed to the connecting holes through the bolt assemblies to fix the photovoltaic module array.

[0012] As a further improvement of the present invention, the storage box is a closed structure with an opening on one side, and a movable door connected to a hinge is provided at the opening of the storage box to facilitate the photovoltaic module array to enter and exit the storage box.

[0013] As a further improvement of the present invention, the support frame is made of metal round tubes.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] 1. The foldable and storable photovoltaic module array of the utility model can realize free movement of the photovoltaic panel modules on the supporting columns by installing buckles on the upper and lower ends of the photovoltaic panel modules and turning the buckles, so that the photovoltaic module array can flexibly adjust the module angle, enhance the efficiency of light utilization, and meet the needs of flexible storage and adjustment of indoor light transmittance; at the same time, the buckles are more weather-resistant than pulleys, effectively avoiding losses caused by derailment in extreme weather, and there is no need to manually clean up debris on the slide rails, thereby ensuring the flexibility of the photovoltaic modules and reducing the operating costs of the photovoltaic modules.

[0016] 2. The foldable and storable photovoltaic module array of the utility model fixes the side of the photovoltaic panel module at the head end of the photovoltaic module array on the supporting column, and adjusts the fixed position of the side of the photovoltaic panel module at the end through the connecting holes on the supporting column, thereby avoiding the need to release and fix the windproof ropes of every two adjacent photovoltaic panel modules in turn when unfolding and closing, further enhancing the function of adjusting the angle and fully unfolding the photovoltaic module array, improving the utilization rate of light, and freely adjusting the light transmittance to the room.

[0017] 3. The foldable and storable photovoltaic module array of the utility model has a storage box arranged on the side of the supporting frame, and the photovoltaic module array can be completely folded and stored in the storage box. The movable door with hinges not only facilitates the photovoltaic modules to enter and exit the storage box, but also realizes the fully enclosed storage of the photovoltaic modules, thereby enhancing the weather resistance and practicality of the photovoltaic modules.

[0026] Example

[0027] like Figures 1 to 4 As shown, the foldable and storable photovoltaic module array of the utility model includes: a support frame 1, a photovoltaic panel assembly 2 and a buckle 3. The support frame 1 adopts a rectangular frame structure, and the support frame 1 is made of a metal round tube. Along the length direction of the support frame 1, support columns 11 are symmetrically provided on both sides of the support frame 1. A plurality of photovoltaic panel assemblies 2 are arranged on the inner side of the support frame 1 to form a photovoltaic module array, and adjacent photovoltaic panel assemblies 2 are hinged by hinges 5. Both ends of a single photovoltaic panel assembly 2 are connected to the support column 11 by buckles 3. When the buckle 3 is turned, the photovoltaic panel assembly 2 can be driven to move back and forth along the support column 11, thereby realizing the folding or unfolding of the photovoltaic module array to any angle.

[0028] In this embodiment, by installing buckle rings 3 at the upper and lower ends of the photovoltaic panel assembly 2 and toggling the buckle rings 3, the photovoltaic panel assembly 2 can be freely moved on the support column 11, and the photovoltaic assembly array can flexibly adjust the assembly angle, enhance the efficiency of light utilization, and meet the needs of flexible storage and adjustment of indoor light transmittance. At the same time, the buckle ring 3 is more weather-resistant than the pulley, effectively avoiding losses caused by derailment in extreme weather, and there is no need to manually clean up debris on the slide rail, ensuring the flexibility of the photovoltaic assembly and reducing the operating cost of the photovoltaic assembly.

[0029] like Figure 4 As shown, in this embodiment, a storage box 6 is provided on the side of the support frame 1, and the storage box 6 is used to accommodate the folded photovoltaic component array.

[0030] Furthermore, the storage box 6 is a closed structure with an opening on one side, and a movable door 61 connected to the hinge 5 is provided at the opening of the storage box 6 to facilitate the photovoltaic module array to enter and exit the storage box 6.

[0031] In this embodiment, a storage box 6 is provided on the side of the support frame 1, and the photovoltaic module array is completely folded and stored in the storage box 6. The movable door 61 with a hinge 5 facilitates the photovoltaic modules to enter and exit the storage box 6, and also realizes the fully enclosed storage of the photovoltaic modules, thereby enhancing the weather resistance and practicality of the photovoltaic modules.

[0032] like Figure 1 As shown, in this embodiment, a plurality of connection holes 12 are evenly distributed on the support column 11. When the photovoltaic module array is unfolded to a preset angle inside the support frame 1, the buckles 3 on both sides of the photovoltaic panel assembly 2 are connected and fixed to the connection holes 12 to fix the photovoltaic module array.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, bolt assemblies 4 are provided on the buckles 3 located at the head and the end of the photovoltaic module array. When the photovoltaic module array is unfolded to a preset angle on the inner side of the supporting frame 1, the buckles 3 are connected and fixed to the connecting holes 12 through the bolt assemblies 4, that is, the photovoltaic panel assemblies 2 located at the head and the end of the photovoltaic module array are connected and fixed to the supporting frame 1, thereby finally realizing the fixation of the photovoltaic module array.

[0034] In this embodiment, buckles 3 are installed at both the upper and lower ends of the photovoltaic panel assembly 2, and the buckles 3 are used to move on the support column 11, so that the photovoltaic panel assembly 2 can move freely inside the support frame 1. Furthermore, the photovoltaic panel assembly 2 at the head end of the photovoltaic assembly array cooperates with the connection hole 12 on the support column 11 through the bolt assembly 4 on the buckle 3, so that the photovoltaic panel assembly 2 is fixed to the support frame 1, and the photovoltaic panel assembly 2 at the end is fixed in different connection holes 12 on the support column 11 to adjust the position, thereby realizing the function of fully unfolding, partially folding or fully folding the photovoltaic assembly array.

[0035] like Figure 1 As shown, when the photovoltaic module array is fully unfolded, the photovoltaic panel modules 2 at the head and tail ends are fixed to the outermost connection holes 12 of the support column 11 to form a planar whole. Figure 3 As shown, when the photovoltaic module array is partially unfolded, the photovoltaic module array as a whole presents a wave shape, and the photovoltaic panel assembly 2 at the end is fixed on different connection holes 12 to adjust the angle of the photovoltaic module array. At the same time, different sizes of space appear between the support frame 1 and the photovoltaic module array, thereby adjusting the indoor light transmittance. Figure 4As shown, when the photovoltaic module array is completely closed, the buckles 3 at the upper and lower ends of the photovoltaic panel assembly 2 are tightly attached, and the distance between the photovoltaic panel assemblies 2 is the smallest. Remove the bolt assembly of the photovoltaic panel assembly 2 at the head end, push the photovoltaic module array into the storage box 6 on the side of the support frame 1, and close the movable door 61 to form a closed structure.

[0036] The photovoltaic module array of this embodiment can adjust the module angle, enhance the efficiency of light utilization, and meet the needs of flexible storage and adjustment of indoor light transmittance; it is convenient to install and carry when folded, and storage in the storage box 6 can avoid damage to the modules in extreme weather, thereby improving the convenience, practicality and weather resistance of the photovoltaic module array in building doors, windows and curtain wall scenes.
