[0001] The present application relates to the field of photovoltaic technology, and in particular to a photovoltaic system. Background Art
[0002] With the development of modern industry, the global energy crisis and air pollution are becoming increasingly prominent, and traditional fuel energy sources are dwindling. Because abundant solar radiation is a vital renewable energy source, solar cells, with their ability to convert solar radiation into electricity, have become a focus of attention. To cope with the changing geographical environments and installation angles, foldable photovoltaic systems have emerged. However, when folding and unfolding, the light-receiving surfaces of photovoltaic modules can easily come into contact and wear each other, resulting in reduced light transmittance, lower photoelectric conversion efficiency, and ultimately reduced power generation. Utility Model Content
[0003] Based on this, it is necessary to provide a photovoltaic system to address the problem that when a foldable photovoltaic system switches between folding and unfolding states, the light-receiving surfaces of the photovoltaic modules are prone to contact and collision wear with each other, thereby resulting in a decrease in the light transmittance of the photovoltaic modules, a decrease in the photoelectric conversion efficiency, and ultimately a decrease in power generation.
[0004] A photovoltaic system comprising:
[0005] Photovoltaic assembly; the photovoltaic assembly includes a photovoltaic substrate and a mounting frame, the mounting frame is mounted on the side of the photovoltaic substrate; the number of the photovoltaic assembly is multiple;
[0006] a telescopic assembly, the telescopic assembly being connected between two adjacent photovoltaic assemblies; and the telescopic assembly being rotatably connected to the mounting frame;
[0007] Wherein, when the telescopic assembly rotates relative to the mounting frame, it has a first preset position and a second preset position;
[0008] At the first preset position, the telescopic assembly extends along a first direction, and the plurality of photovoltaic assemblies are sequentially arranged along the first direction;
[0009] In the second preset position, the telescopic component contracts along the second direction, and the plurality of photovoltaic components are arranged in sequence along the second direction; the second direction is arranged at an angle to the first direction; the light-receiving surface of one of the two adjacent photovoltaic components is arranged opposite to the backlight surface of the other.
[0010] In one embodiment, the telescopic assembly includes two connecting members and a telescopic member;
[0011] The two connecting members are respectively passed through the mounting frame of one of the two adjacent photovoltaic assemblies;
[0012] One end of the telescopic member is rotatably connected to one of the connecting members, and the other end of the telescopic member is rotatably connected to the other connecting member.
[0013] In one embodiment, the telescopic assembly further includes a rotating member; the rotating member is sleeved on the outer periphery of the connecting member and fixedly connected to the connecting member;
[0014] The rotating member is configured with a rotating groove, and the end portion of the telescopic member is sleeved in the rotating groove and can rotate relative to the groove wall of the rotating groove.
[0015] In one embodiment, the rotation angle θ of the telescopic member relative to the groove wall of the rotation groove satisfies the condition:
[0016] 0°≤θ≤360°.
[0017] In one embodiment, the connecting member includes a first connecting segment, a second connecting segment, and a third connecting segment connected in sequence;
[0018] And along the axial direction of the connecting member, the outer contour of the orthographic projection of the first connecting segment is located outside the outer contour of the orthographic projection of the second connecting segment; the outer contour of the orthographic projection of the third connecting segment is located outside the outer contour of the orthographic projection of the second connecting segment;
[0019] The rotating member and the mounting frame are both sleeved on the outer circumference of the second connecting section and fixedly connected to the second connecting section.
[0020] In one embodiment, the telescopic member includes a plurality of adjusting rods arranged in sequence, and two adjacent adjusting rods are slidably connected to each other;

[0026] In one embodiment, at least two groups of the telescopic components are installed between two adjacent photovoltaic components, and the at least two groups of the telescopic components are arranged opposite to each other.
[0027] When the photovoltaic system needs to be transported or installed, it is necessary to switch between a folded and unfolded state, that is, to rotate the telescopic assembly relative to the mounting frame to a first preset position or a second preset position to switch positions. At this time, since in the second preset position, that is, when the photovoltaic system is in the folded state, the light-receiving surface of one of the two adjacent photovoltaic assemblies is arranged opposite the backlight surface of the other, the light-receiving surfaces of the photovoltaic assemblies do not contact each other and thus do not collide and wear. This effectively ensures that when the telescopic assembly is rotated again relative to the mounting frame to the first preset position, that is, when the photovoltaic system is in the unfolded state, the light transmittance of the light-receiving surfaces of the photovoltaic assemblies is not easily reduced, effectively ensuring photoelectric conversion efficiency and power generation. The photovoltaic system can not only be switched to the folded state of the second preset position during transportation, making packaging, transportation, and handling processes simpler and more convenient; but also can be promptly switched to the unfolded state of the first preset position upon arrival at the destination, making the entire installation process more convenient and achieving higher photoelectric conversion efficiency and power generation.

[0044] See Figure 1 and combined Figure 2-Figure 6 , Figure 1 A schematic diagram of a photovoltaic system provided by some embodiments of the present application is shown. Figure 2 Shown Figure 1 The photovoltaic system is shown in a side view showing the connection between the photovoltaic assembly 100 and the telescopic assembly 200 . Figure 3 Shown Figure 1 The photovoltaic system is shown in a schematic diagram at one of the first preset positions. Figure 4 Shown Figure 1 The photovoltaic system is shown in another schematic diagram of the first preset position. Figure 5 Shown Figure 1 A first schematic diagram of the photovoltaic system shown is in a second preset position. Figure 6 Shown Figure 1 A second schematic diagram of the photovoltaic system shown is in a second preset position.
[0045] A photovoltaic system provided by an embodiment of the present application includes a photovoltaic module 100 and a telescopic module 200. The photovoltaic module 100 includes a photovoltaic substrate 110 and a mounting frame 120, wherein the mounting frame 120 is mounted on the side of the photovoltaic substrate 110; the number of photovoltaic modules 100 is multiple; the telescopic module 200 is connected between two adjacent photovoltaic modules 100; and the telescopic module 200 is rotatably connected to the mounting frame 120; wherein, when the telescopic module 200 rotates relative to the mounting frame 120, it has a first preset position and a second preset position; in the first preset position (e.g., Figure 3 and Figure 4 As shown in FIG), the telescopic assembly 200 extends along a first direction, and a plurality of photovoltaic assemblies 100 are sequentially arranged along the first direction; specifically, the first direction is Figure 3 and Figure 4 xx' direction; at the second preset position (such as Figure 5 and Figure 6 As shown), the telescopic assembly 200 contracts along the second direction, and the plurality of photovoltaic assemblies 100 are sequentially arranged along the second direction; the second direction is arranged at an angle to the first direction; specifically, the second direction is Figure 5 and Figure 6 the light-receiving surface 111 of one of the two adjacent photovoltaic modules 100 is disposed opposite to the backlight surface 112 of the other.
[0046] When the photovoltaic system needs to be transported or installed, it is necessary to switch between a folded and unfolded state. Specifically, the telescopic assembly 200 is rotated relative to the mounting frame 120 to either a first preset position or a second preset position to switch positions. At this time, since in the second preset position (i.e., when the photovoltaic system is in the folded state), the light-receiving surface 111 of one of the two adjacent photovoltaic assemblies 100 is positioned opposite the light-receiving surface 112 of the other, the light-receiving surfaces 111 of the photovoltaic assemblies 100 do not contact each other and thus do not collide and wear. This effectively ensures that when the telescopic assembly 200 is rotated again relative to the mounting frame 120 to the first preset position (i.e., when the photovoltaic system is in the unfolded state), the light transmittance of the light-receiving surfaces 111 of the photovoltaic assemblies 100 is not easily reduced, thereby effectively ensuring photoelectric conversion efficiency and power generation. The photovoltaic system can not only be switched to the folded state in the second preset position during transportation, making packaging, transportation, and handling simpler and more convenient, but can also be promptly switched to the unfolded state in the first preset position upon arrival at the destination, making the entire installation process more convenient and achieving higher photoelectric conversion efficiency and power generation.
[0047] The photovoltaic system provided in the present application can provide a protective operation for the mounting frame 120 . When the photovoltaic system switches between folding and unfolding states, the mounting frame 120 is not easily damaged by torque.
[0048] The following is a detailed description of the structure of the photovoltaic system. Figure 7-Figure 9 , Figure 7 Shown Figure 6 The photovoltaic system is shown in a schematic diagram of the connection between the mounting frame 120 and the telescopic assembly 200 in the second preset position. Figure 8 Shown Figure 6 FIG. 1 is a schematic diagram of a telescopic member 220 in a photovoltaic system. Figure 9 Shown Figure 6 FIG. 2 is a schematic diagram of a connector 210 in a photovoltaic system.
[0049] See also Figure 3 、 Figure 4 and Figure 6 In some embodiments, the telescopic assembly 200 includes two connecting members 210 and a telescopic member 220; the two connecting members 210 are respectively passed through the mounting frame 120 of one of the two adjacent photovoltaic assemblies 100; one end of the telescopic member 220 is rotatably connected to one of the connecting members 210, and the other end of the telescopic member 220 is rotatably connected to the other of the connecting members 210. By providing the two connecting members 210 and the one telescopic member 220 in coordination, when the photovoltaic system needs to be switched between the first preset position and the second preset position, the position of the two adjacent photovoltaic assemblies 100 can be changed by extending and retracting the telescopic member 220 in combination with the rotation of the connecting member 210, which is relatively simple and convenient.
[0050] See also Figure 6 and Figure 7 In some embodiments, the telescopic assembly 200 further includes a rotating member 230; the rotating member 230 is sleeved around the outer periphery of the connecting member 210 and fixedly connected to the connecting member 210; the rotating member 230 is configured with a rotating groove 231, and the end of the telescopic member 220 is sleeved in the rotating groove 231 and can rotate relative to the groove wall of the rotating groove 231. By providing the rotating member 230 and providing the rotating groove 231 on the rotating member 230 for sleeved the end of the telescopic member 220, when the telescopic member 220 rotates relative to the rotating member 230, the side walls of the rotating groove 231 can limit the telescopic member 220 from separating from the rotating member 230, and the rotation process of the telescopic member 220 is more stable.
[0051] In some embodiments, the rotation angle θ of the telescopic member 220 relative to the groove wall of the rotation groove 231 satisfies the condition: 0°≤θ≤360°. By setting the rotation angle θ of the telescopic member 220 relative to the groove wall of the rotation groove 231 to be greater than or equal to 0° and less than or equal to 360°, when the photovoltaic system is switched from the unfolded state of the first preset position to the folded state of the second preset position, the upper photovoltaic assembly 100 adjacent to one of the photovoltaic assemblies 100 can be folded or unfolded, and the lower photovoltaic assembly 100 adjacent to the photovoltaic assembly 100 can also be folded or unfolded, making the entire state switching process more convenient.
[0052] See also Figure 7 and Figure 9 In some embodiments, the connecting member 210 includes a first connecting segment 211, a second connecting segment 212, and a third connecting segment 213 connected in sequence. Along the axial direction of the connecting member 210, the outer contour of the orthographic projection of the first connecting segment 211 is located outside the outer contour of the orthographic projection of the second connecting segment 212; the outer contour of the orthographic projection of the third connecting segment 213 is located outside the outer contour of the orthographic projection of the second connecting segment 212; and the rotating member 230 and the mounting frame 120 are both sleeved around the outer circumference of the second connecting segment 212 and fixedly connected to the second connecting segment 212. This arrangement ensures that when the rotating member 230 and the mounting frame 120 are sleeved around the outer circumference of the second connecting segment 212, the rotating member 230 and the mounting frame 120 are prevented from sliding along the axial direction of the connecting member 210 and separating from the connecting member 210 due to the restraining effect of the first connecting segment 211 and the third connecting segment 213, thereby ensuring high installation stability of the rotating member 230 and the mounting frame 120.
[0053] It should be noted that the first connecting section 211 and the third connecting section 213 of the connecting member 210 can be rivets, which are connected to the second connecting section 212 through rivets, so that it is more convenient to install the rotating member 230 and the mounting frame 120 on the second connecting section 212.
[0054] See also Figure 8 In some embodiments, the telescopic member 220 includes a plurality of adjustment rods 221 arranged in sequence, and two adjacent adjustment rods 221 are slidably connected to each other; each adjustment rod 221 is also configured with a limiting portion 222, and when two adjacent adjustment rods 221 slide to a limited position, the limiting portion 222 can limit the relative sliding of the adjustment rods 221. By such a configuration, the length of the telescopic member 220 can be changed and can be fixed accordingly at a specific length, for example Figure 3 and Figure 4 As shown, thus meeting the installation requirements of different installation gaps ( Figure 3 The installation gaps between adjacent photovoltaic modules 100 are relatively large. Figure 4 The installation gap between adjacent photovoltaic modules 100 is smaller.
[0055] In some embodiments, the minimum length d of the telescopic member 220 and the thickness h of the photovoltaic assembly 100 satisfy the condition: d>2h. By setting the minimum length d of the telescopic member 220 to be greater than or equal to twice the thickness h of the photovoltaic assembly 100, the photovoltaic system can be folded. Figure 5 and Figure 6 In the state shown, the photovoltaic modules 100 are less likely to come into contact with each other and collide and wear each other, thereby reducing the impact on the transmittance of the photovoltaic modules 100 .
[0056] See also Figure 6 In some embodiments, the connector 210 is installed on the backlight side 112 of the photovoltaic module 100. By installing the connector 210 on the backlight side 112 of the photovoltaic module 100, the shielding of the light-receiving surface 111 of the photovoltaic module 100 by the connector 210 is reduced, and the effective illumination area of the light-receiving surface 111 of the photovoltaic module 100 is increased, thereby improving the photoelectric conversion efficiency and power generation.
[0057] See also Figure 7 In some embodiments, the telescopic assembly 200 further includes a damper 240, which is mounted on the telescopic member 220. By providing the damper 240 on the telescopic member 220, the telescopic member 220 can be more stable and labor-saving when telescoping, thereby reducing the shaking of the photovoltaic assembly 100 and effectively reducing the shaking damage to the photovoltaic assembly 100.
[0058] See also Figure 3 、 Figure 4 and Figure 6 In some embodiments, at least two sets of telescopic assemblies 200 are installed between two adjacent photovoltaic assemblies 100, and the at least two sets of telescopic assemblies 200 are arranged opposite each other. By installing at least two sets of telescopic assemblies 200 between two adjacent photovoltaic assemblies 100 and arranging them opposite each other, the photovoltaic system can switch between the folding and unfolding states more smoothly.
[0059] In one specific embodiment, two sets of telescopic assemblies 200 are installed between two adjacent photovoltaic modules 100, and the two sets of telescopic assemblies 200 are arranged opposite each other. In another specific embodiment, three sets of telescopic assemblies 200 are installed between two adjacent photovoltaic modules 100, with one set on one side of the photovoltaic module 100 and the other two sets on the opposite side of the photovoltaic module 100. Of course, in other embodiments, four, five, or six sets of telescopic assemblies 200 may be installed between two adjacent photovoltaic modules 100, and this is not particularly limited. The number of telescopic assemblies 200 can be adaptively increased or decreased according to the size of the photovoltaic module 100.
[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
