[0038] The snow blocking device for a photovoltaic module and a distributed photovoltaic array according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0039] Figure 1 It is a schematic structural diagram of the snow blocking device for a photovoltaic module provided by an embodiment of the present application; Figure 2 It is a schematic structural diagram of the cooperation between the snow blocking device for a photovoltaic module and a photovoltaic module provided by an embodiment of the present application; Figure 3 It is a front view of the snow blocking device for a photovoltaic module provided by an embodiment of the present application; Figure 4 It is a schematic structural diagram of the snow blocking device for a photovoltaic module provided by an embodiment of the present application applied in a distributed photovoltaic array; Figure 5 It is a schematic diagram of another structure of the snow blocking device for a photovoltaic module provided by an embodiment of the present application; Figure 6 It is a schematic diagram of still another structure of the snow blocking device for a photovoltaic module provided by an embodiment of the present application.

[0040] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 An embodiment of the present application provides a snow blocking device 100 for a photovoltaic module, including a baffle 10, side plates 20, and first connecting plates 30 and second connecting plates 50 that are oppositely arranged.

[0041] Both ends of the side plate 20 are respectively connected to the facing surfaces of the first connecting plate 30 and the second connecting plate 50, so as to jointly define two accommodating grooves R that are opposite to each other and can accommodate the frame of the photovoltaic module 40 between the side plate 20 and the first connecting plate 30 and the second connecting plate 50. The baffle 10 is connected to the side of the first connecting plate 30 away from the side plate 20. Here, the fact that the accommodating groove R can accommodate the frame of the photovoltaic module 40 means that the frame of the photovoltaic module 40 can at least partially extend into the accommodating groove R.

[0042] The two ends of the side plate 20 are respectively connected to the surfaces of the first connecting plate 30 and the second connecting plate 50 facing each other, so that the side plate 20 and the first connecting plate 30 and the second connecting plate 50 define two mutually opposite accommodating grooves R that can accommodate the frame of the photovoltaic assembly 40. During installation, the photovoltaic assembly snow shielding device 100 only needs to be inserted into the gap between two adjacent photovoltaic assemblies 40, and the first connecting plate 30 is blocked on one side of the thickness direction of the two adjacent photovoltaic assemblies 40, such as the upper surface of the frame of the photovoltaic assembly 40 (frame a surface), and the second connecting plate 50 is blocked on the other side of the thickness direction of the two adjacent photovoltaic assemblies 40, such as the lower surface of the frame of the photovoltaic assembly 40 (frame c surface) and the first connecting plate 30 is facing upward, so that the photovoltaic assembly snow shielding device 100 can be installed, and the installation process is relatively simple and time-consuming. After installation, the baffle 10 can play a role in snow blocking.

[0043] In a specific implementation, the baffle 10 can be arranged perpendicular to the first connecting plate 30. The first connecting plate 30 is arranged on the light-facing side of the frame of the photovoltaic module 40. In order to avoid excessive shielding of the solar cells in the photovoltaic module 40 and cause a hot spot effect, the setting range of the first connecting plate 30 should be smaller than or equal to the setting range of the frame of the photovoltaic module 40 on the light-facing side. By connecting the side plate 20 between the first connecting plate 30 and the second connecting plate 50, the first connecting plate 30, the second connecting plate 50 and the side plate 20 jointly define a structure with an "I"-shaped cross section. The frames of two adjacent photovoltaic modules 40 can be respectively accommodated in a receiving groove R.

[0044] In the embodiment of the present application, the baffle 10 is biased to the side of the first connecting plate 30 away from the shielding side, and the shielding side is the side facing away from the illumination side. In specific implementation, the baffle 10 is arranged at the end of the first connecting plate 30 along the first direction F. Among them, the first direction F is the inclination direction of the installation of the photovoltaic assembly 40. With such a configuration, when specifically installed, as long as the baffle 10 is located on the lower side of the inclination direction of the photovoltaic assembly 40, the snow blocking effect is best. In addition, the shielding area of ​​the baffle 10 on the upper side of the inclination direction of the photovoltaic assembly 40 can also be reduced, thereby avoiding the hot spot effect. Here, it should be noted that the lower side of the inclination direction of the photovoltaic assembly 40 points to the sunny side, and it should be installed on the upper side of the inclination direction when installed on the north slope of the sloping roof.

[0045] In the embodiment of the present application, further, the side panel 20 includes a first sub-side panel 21 and a second sub-side panel 22 which are spaced apart from each other, and both ends of the first sub-side panel 21 and both ends of the second sub-side panel 22 are respectively connected to the first connecting plate 30 and the second connecting plate 50.

[0046] With such a setting, a cavity Z is formed between the first sub-side plate 21 and the second sub-side plate 22. In the case of high temperature, when the distance between adjacent photovoltaic modules 40 changes, the existence of this cavity Z allows the adjacent photovoltaic modules 40 to approach each other without squeezing and damaging the photovoltaic modules 40. Additionally, it can save materials and reduce costs. Further, it can also be used to control the distance between two adjacent groups of photovoltaic modules 40, and control the distance between two adjacent photovoltaic modules 40 through the thickness of the side plate 20 or the distance between the first sub-side plate 21 and the second sub-side plate 22, so as to standardize the installation of the photovoltaic modules 40 and improve the standardization degree of the construction of the distributed photovoltaic power station. Of course, the side plate 20 can also be as Figure 5 formed into an integrally formed structure like that, which is convenient for processing.

[0047] In the embodiment of the present application, the baffle 10 is configured as a long strip-shaped structure extending along the second direction S. Among them, the second direction S is perpendicular to the relative direction of the first connection plate 30 and the second connection plate 50, and parallel to the side plate 20. In other words, the second direction S is along the long side frame or short side frame direction of the photovoltaic module 40.

[0048] With such a setting, when the side plate 20 of the photovoltaic module snow blocking device 100 is clamped between two photovoltaic modules 40, the baffle 10 can extend along the edge of the frame of the photovoltaic module 40, and the snow blocking effect is better.

[0049] Further, continue to refer to Figure 5 , a plurality of through holes 11 are provided at the position of the baffle 10 adjacent to the first connection plate 30, and the plurality of through holes 11 are arranged at intervals along the second direction S.

[0050] The cross-section of the through hole 11 can be circular or other shapes. From an economic perspective, the setting of the through holes 11 can reduce the material usage of the photovoltaic module snow blocking device 100 and reduce costs. From a technical perspective, by providing the through holes 11, it can be used for rapid ash discharge and drainage. While ensuring the snow blocking effect, it also avoids leaving accumulated ash at the junction position of the baffle 10 and the first connection plate 30 due to rainwater scouring during rainy weather, which affects the power generation. Specifically, when implemented, the position of the through holes 11 can be set at a position adjacent to the first connection plate 30, and the intervals of the plurality of through holes 11 along the second direction S are the same.

[0051] Refer to Figure 6 , in some other embodiments, the baffle 10 includes a plurality of sub-baffles 12 arranged at intervals along the second direction S. With such a setting, the weight of the entire photovoltaic module snow blocking device 100 can be reduced, and the material cost can be saved. The intervals between the respective sub-baffles 12 can be equal, and the intervals between the respective sub-baffles 12 can be designed as needed.

[0052] Further, continue to refer toFigure 2 Moreover, the first connecting plate 30 and the second connecting plate 50 can also be arranged parallel to each other, and the side plate 20 is perpendicular to the first connecting plate 30. With such an arrangement, the accommodation groove R formed between the first connecting plate 30, the second connecting plate 50 and the side plate 20 can match the shape of the edge side of the photovoltaic module 40.

[0053] In the embodiment of the present application, the distance between the first connecting plate 30 and the second connecting plate 50 matches the thickness of the photovoltaic module 40. In this way, the snow shielding device 100 for photovoltaic modules can be stably installed between the photovoltaic modules 40. During use, the snow shielding device 100 for photovoltaic modules can be prevented from shaking relative to the photovoltaic modules 40. In other words, the frames of two adjacent groups of photovoltaic modules 40 cooperate with the accommodation grooves R on both sides of the snow shielding device 100 for photovoltaic modules, enabling the snow shielding device 100 for photovoltaic modules to be fixed reliably, and the load borne by the snow shielding device 100 for photovoltaic modules can be effectively transmitted to the photovoltaic modules 40 to share the force and improve the snow shielding ability.

[0054] Figure 7 It is a schematic diagram of a partial structure of a distributed photovoltaic array provided by an embodiment of the present application. Figure 8 It is a schematic diagram of a module structure of a distributed photovoltaic array provided by an embodiment of the present application. Figure 9 It is a schematic diagram of the installation situation of a distributed photovoltaic array provided by an embodiment of the present application.

[0055] Referring to Figure 7 and Figure 8 , an embodiment of the present application further provides a distributed photovoltaic array 200, including a plurality of photovoltaic modules 40. The plurality of photovoltaic modules 40 are spaced apart from each other, located in the same plane, and arranged in an array. The whole of the plurality of photovoltaic modules 40 is arranged obliquely with respect to the horizontal plane.

[0056] At least one of the above-mentioned snow shielding devices 100 for photovoltaic modules is connected between two adjacent photovoltaic modules 40 in the column direction. With such an arrangement, a snow shielding device 100 for photovoltaic modules is provided at the lower side in the inclined direction of the photovoltaic module 40 to block the snow on the corresponding photovoltaic module 40.

[0057] Furthermore, at least some of the snow shielding devices 100 for photovoltaic modules located in different columns are arranged staggeredly in the row direction of the array arrangement. Here, for the snow shielding devices 100 for photovoltaic modules located in different columns, for example, at least some of the snow shielding devices 100 for photovoltaic modules in the adjacent columns can be arranged staggeredly in the row direction of the array arrangement, or all the snow shielding devices 100 for photovoltaic modules in all columns can be arranged staggeredly in the row direction of the array arrangement.

[0058] With such an arrangement, the snow shielding function at as many positions as possible in the row direction can be realized with a smaller quantity.

[0059] In specific implementation, such as Figure 8 Among them, one row of photovoltaic module snow blocking devices 100 located on the lower side of the inclination direction of each photovoltaic module 40 is staggered from one row of photovoltaic module snow blocking devices 100 on its upper side in the row direction. In this way, even if the part of the snow that is not blocked by the photovoltaic module snow blocking device 100 on the upper photovoltaic module 40 slides down to the lower photovoltaic module 40, it can be blocked by the photovoltaic module snow blocking device 100 corresponding to the lower photovoltaic module 40.

[0060] Furthermore, referring to Figure 9 It shows the installation of the distributed photovoltaic array 200 on the south slope 202 and the north slope 203 of the top of the house 201. The light direction is shown by the black straight arrows in the figure.

[0061] From Figure 9 It can be seen that when the distributed photovoltaic array 200 is installed on the south slope 202, the shielding area 204 of the baffle 10, that is, the shielding side, as Figure 9 Shown in the figure, is on the side of the baffle 10 facing away from the light, and the baffle 10 is on the side away from the shielding side, that is, it is offset to one side of the light side.

[0062] And when the distributed photovoltaic array 200 is installed on the north slope 203, the shielding area 204 of the baffle 10, that is, the shielding area, as Figure 9 Shown in the figure, is on the side of the baffle 10 facing away from the light, and the baffle 10 is on the side away from the shielding side, that is, it is offset to one side of the light side.

[0063] It can be seen from this that no matter it is installed on the south slope 202 or the north slope 203, the shielding area 204 generated by the baffle 10 falls on the first connecting plate 30 and will not affect the photovoltaic module 40.

[0064] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0065] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
