[0036] A photovoltaic snow shield assembly 100 according to an embodiment of the present application will be described below with reference to the drawings.

[0037] Referring to Figures 1-4 As shown, the photovoltaic snow shield assembly 100 according to the embodiment of the present application can include a mounting member 10 and a snow shield member 20.

[0038] Specifically, the mounting member 10 includes a mounting portion 11 for mounting to a mounting bracket 210 of a photovoltaic assembly 220 and a press-fit portion 12 provided on the mounting portion 11 and configured to be press-fitted to an edge of the photovoltaic assembly 220. The snow shield member 20 includes a connecting portion 21 mounted to the mounting portion 11 and a vertical plate 22 provided above the connecting portion 21, such that when the press-fit portion 12 is press-fitted to the edge of the photovoltaic assembly 220, the vertical plate 22 protrudes from a surface of the photovoltaic assembly 220.

[0039] Mounting frame 210 refers to a frame used to install and fix photovoltaic module 220. For example, mounting frame 210 installs and fixes photovoltaic module 220 to the roof. The specific structure of mounting frame 210 is not limited. For example, mounting frame 210 may include multiple connected beams, and mounting part 11 may be connected to the beams to realize the installation of mounting component 10 on mounting frame 210.

[0040] The crimping part 12 and the mounting part 11 can be integrally formed, or they can be connected together by welding, snap-fitting, or other methods. The edge of the photovoltaic module 220 can refer to the frame 230 of the photovoltaic module 220. The crimping part 12 can be crimped onto the frame 230 to avoid direct contact with the glass components of the photovoltaic module 220. "The crimping part 12 is crimped onto the edge of the photovoltaic module 220" means that the crimping part 12 is crimped onto the side of the edge of the photovoltaic module 220 facing away from the roof.

[0041] The connecting part 21 and the upright plate 22 of the snow shield 20 can be integrally formed, or they can be connected together by welding, snap-fitting, or other methods. The connecting part 21 is installed on the mounting part 11 to realize the installation of the snow shield 20 on the mounting part 10, thereby realizing the installation and fixation of the snow shield 20 relative to the photovoltaic module 220, so that the snow shield 20 can treat the snow, thin ice, etc. on the surface of the photovoltaic module 220.

[0042] The support plate 22 is located above the connecting part 21. Here, "above" can mean directly above or diagonally above, referring to the side of the connecting part 21 facing away from the roof. The support plate 22 can directly contact and treat snow, thin ice, etc. on the surface of the photovoltaic module 220 to reduce damage to people and property.

[0043] In related technologies, snow barriers are directly installed on photovoltaic modules, meaning they are in direct contact and connection with the modules. To improve snow removal efficiency, snow barriers typically require high rigidity, and the connection between the snow barrier and the photovoltaic module needs to be very secure. Therefore, when the snow barrier is subjected to the weight and impact of snow, a significant load is transferred to the photovoltaic module, making it prone to damage.

[0044] In the embodiments of this application, the snow-blocking component 20 uses the mounting component 10 as a carrier, and the mounting component 10 is mounted on the mounting frame 210, rather than directly on the photovoltaic module 220. The mounting component 10 and the photovoltaic module 220 are only connected by a pressing part 12. When the snow-blocking component 20 is subjected to the force of accumulated snow, most of the load is transferred to the mounting frame 210 through the mounting component 10, and only a small amount of load is applied to the photovoltaic module 220. Furthermore, under the action of accumulated snow, the pressing fit structure between the pressing part 12 and the photovoltaic module 220 is prone to slight displacement. Without affecting the snow-blocking function, the force transmission between the pressing part 12 and the photovoltaic module 220 can be further improved, further reducing damage to the photovoltaic module 220.

[0045] According to the photovoltaic snow blocking assembly 100, the mounting piece 10 is used for mounting the snow blocking piece 20 on the mounting rack 210, and the mounting piece 10 is matched with the photovoltaic assembly 220 through the crimping part 12, so that the damage risk of the photovoltaic assembly 220 is reduced and the reliability of the photovoltaic assembly 220 is improved under the condition of meeting the snow blocking requirement.

[0046] According to some embodiments of the present application, as shown in Figures 1-4 The mounting part 11 has a receiving groove 111, the receiving groove 111 has a top notch, the snow blocking piece 20 is arranged in the top notch, the connecting part 21 is arranged in the receiving groove 111, and the vertical plate 22 is located outside the receiving groove 111.

[0047] In the assembly process, the snow blocking piece 20 is inserted into the receiving groove 111 from the top notch, so that the connecting part 21 is matched with the groove wall of the receiving groove 111 to realize reliable matching of the snow blocking piece 20 and the mounting piece 10, and the snow blocking piece 20 is not easy to move greatly to affect the snow blocking effect; and the assembly mode of the snow blocking piece 20 and the mounting piece 10 is simple, and the assembly efficiency is high. The vertical plate 22 is located outside the receiving groove 111, so that the vertical plate 22 is in contact with the snow and processes the snow.

[0048] It is worth noting that the receiving groove 111 can only have the top notch and other sides without notches to improve the limiting effect of the snow blocking piece 20; or the receiving groove 111 can also have a side notch as shown in Figures 1-4 The mounting part 11 has a first wall surface opposite to the photovoltaic assembly 220 and a second wall surface adjacent to the photovoltaic assembly 220, the first wall surface can be in contact with or spaced apart from the edge of the photovoltaic assembly 220 by a certain gap, the second wall surface can be connected with the first wall surface in the circumferential direction of the mounting part 11, and the side notch can be arranged on the second wall surface, so as to increase the matching area of the first wall surface and the photovoltaic assembly 220, improve the structural stability of the mounting piece 10, and facilitate the disassembly and assembly of the connecting part 21 and the mounting part 11 under the condition that the crimping part 12 is crimped on the edge of the photovoltaic assembly 220.

[0049] In some embodiments, continuing to refer to Figures 1-4 The crimping part 12 is arranged on the outer circumferential surface of the mounting part 11 and connected with the edge of the top notch. For example, the crimping part 12 can be an outward turning edge arranged on the edge of the top notch, and the structure of the mounting piece 10 is simpler and easier to process.

[0050] In some embodiments of the present application, as shown in Figures 1-4 The photovoltaic snow blocking assembly 100 further comprises a fastener 30, the fastener 30 is arranged in the connecting part 21 and the mounting part 11, and connected with the mounting rack 210.

[0051] For example, the fastener 30 can include a bolt and a nut 31, the bolt is threaded into the connecting part 21, the mounting part 11 and the mounting rack 210 and is screwed with the nut 31. Of course, the fastener 30 can also be a buckle or other structure, as long as it can realize the reliable installation of the photovoltaic snow blocking assembly 100 and the mounting rack 210.

[0052] The fastener 30 can realize the connection between the snow blocking part 20 and the mounting part 10, and also realize the connection between the photovoltaic snow blocking assembly 100 and the mounting rack 210, which is beneficial to reduce the number of parts and improve the assembly efficiency. In addition, the mounting part 11 is clamped between the connecting part 21 and the mounting rack 210, and the mounting part 11 does not directly bear the action force of the fastener 30, for example, does not directly bear the pressing force of the screw head of the bolt or the nut 31, and the snow blocking part 20 plays the role of a gasket, so that the damage to the mounting part 10 can be reduced, and the mounting part 10 is not easy to be damaged even if a material with smaller hardness is used.

[0053] In some embodiments, as shown in FIG. 1, Figure 5 The connecting part 21 has a cavity 211, and the cavity 211 has at least one avoiding port 212 for moving the fastener 30 into the cavity 211. Among them, the avoiding port 212 faces upward; or the avoiding port 212 is arranged on the wall surface of the connecting part 21 adjacent to the photovoltaic assembly 220; or part of the avoiding port 212 faces upward, and part of the avoiding port 212 is arranged on the wall surface of the connecting part 21 adjacent to the photovoltaic assembly 220.

[0054] The avoiding port 212 faces upward or is arranged on the wall surface of the connecting part 21 adjacent to the photovoltaic assembly 220, which can make the avoiding port 212 not be blocked by the photovoltaic assembly 220 after the mounting part 10 cooperates with the photovoltaic assembly 220 and the snow blocking part 20 cooperates with the mounting part 10, so as to facilitate the fastener 30 to be assembled into the cavity 211 through the avoiding port 212, and then realize the fastening of the snow blocking part 20, the mounting part 10 and the mounting rack 210. After installation, the cavity 211 can accommodate the fastener 30, for example, accommodate the head of the bolt, so that the fastener 30 is not exposed and is easy to be loosened by being touched, thereby improving the reliability of the connection.

[0055] In some specific embodiments, as shown in FIG. 1, Figure 5 At least two avoiding ports 212 are arranged on different sides of the connecting part 21, so that in the actual assembly process, the appropriate avoiding port 212 can be selected for fastener 30 assembly according to the limitation of the operation tool, operation space and the like, so that the assembly is more convenient.

[0056] According to some embodiments of the present application, the hardness of the snow blocking member 20 is greater than the hardness of the mounting member 10. The mounting member 10 directly contacts the photovoltaic module 220, and the smaller hardness of the mounting member 10 can reduce the risk of damage to the photovoltaic module 220. The mounting member 10 with smaller hardness is easier to process to obtain a more complex structure to meet the assembly requirements. The snow blocking member 20 directly bears the force of accumulated snow and thin ice, and the greater hardness of the snow blocking member 20 can meet the snow blocking reliability, and the snow blocking member 20 is not easy to deform or damage. For example, the snow blocking member 20 can be made of steel or other materials, and the mounting member 10 can be made of aluminum or other materials.

[0057] As shown in Figure 1 , Figure 3 and Figures 6-7 , the photovoltaic system 200 according to the embodiments of the present application includes a mounting rack 210, a photovoltaic module 220, and a photovoltaic snow blocking assembly 100 according to the embodiments of the present application. The photovoltaic module 220 is mounted on the mounting rack 210, and the photovoltaic snow blocking assembly 100 is mounted on the mounting rack 210 and the pressure contact portion 12 is arranged on the edge of the photovoltaic module 220.

[0058] Since the photovoltaic snow blocking assembly 100 according to the embodiments of the present application has the above beneficial technical effects, the photovoltaic system 200 according to the embodiments of the present application installs the snow blocking member 20 on the mounting rack 210 through the mounting member 10, and the mounting member 10 cooperates with the photovoltaic module 220 through the pressure contact portion 12. Under the condition of meeting the snow blocking requirement, the photovoltaic module 220 can reduce the force received from the photovoltaic snow blocking assembly 100, thereby reducing the damage risk of the photovoltaic module 220 and improving the reliability of the photovoltaic module 220.

[0059] In some embodiments, as shown in Figure 6 and Figure 7 , the photovoltaic snow blocking assembly 100 is a plurality of photovoltaic snow blocking assemblies 100 arranged in multiple layers, and each layer includes a plurality of photovoltaic snow blocking assemblies 100 arranged in a horizontal direction.

[0060] For an inclined roof, the multiple layers of photovoltaic snow blocking assemblies 100 can be arranged in the up-down direction of the roof to form multiple layers of blocking lines in the direction of the snow sliding. The multiple layers of blocking lines are better for reducing the size of large snow, thereby reducing the volume of snow sliding to the ground and reducing damage to personnel and property.

[0061] In addition, the snow on the roof can form thin ice after melting, and thin ice is more likely to form near the upper part of the roof. The thin ice on the upper part of the roof slides down along the inclined roof, and the impact force of the thin ice on the snow baffle is greater if only one layer of snow baffle is arranged at the eaves in the related art, thereby causing greater damage to the photovoltaic module. The risk of injury to personnel is still present after the thin ice is cut and falls. The above embodiments of the present application can block the snow and thin ice in different areas in the upward and downward directions of the roof by arranging multiple layers of photovoltaic snow blocking assemblies 100. The soft snow can form a smaller volume to reduce the risk of injury to personnel, and the thin ice with greater hardness is blocked by the multiple layers of photovoltaic snow blocking assemblies 100, so that a greater impact force is not formed between them, so that the thin ice is not easily cut by the photovoltaic snow blocking assembly 100 and slides downward, but slowly melts and drips, thereby reducing damage to personnel and property.

[0062] For the multiple layers of photovoltaic snow blocking assemblies 100, in some specific embodiments, they can be arranged one by one in the horizontal direction, for example Figure 6 As shown in FIG. 1, six photovoltaic snow blocking assemblies 100 are arranged on each layer, and the arrangement positions of any two adjacent photovoltaic snow blocking assemblies 100 in the horizontal direction are the same.

[0063] Or in another specific embodiment, the two adjacent layers of photovoltaic snow blocking assemblies 100 are arranged staggered in the horizontal direction, for example Figure 7 As shown in FIG. 2, the photovoltaic snow blocking assembly 100 of one of the two adjacent layers of photovoltaic snow blocking assemblies 100 is located between the two photovoltaic snow blocking assemblies 100 of the other layer. The staggered arrangement makes the multiple layers of photovoltaic snow blocking assemblies 100 have a better blocking effect on thin ice and a better effect of preventing thin ice from sliding down.

[0064] In some embodiments of the present application, as shown in Figure 6 and Figure 7 The multiple photovoltaic snow blocking assemblies 100 include a first photovoltaic snow blocking assembly 100a and a second photovoltaic snow blocking assembly 100b.

[0065] As shown in Figures 1-2 and Figures 6-7 The first photovoltaic snow blocking assembly 100a is arranged between the two adjacent layers of photovoltaic assemblies 220, and the first photovoltaic snow blocking assembly 100a has two pressing portions 12, and the two pressing portions 12 of the same first photovoltaic snow blocking assembly 100a are respectively arranged at the edges of the two adjacent layers of photovoltaic assemblies 220.

[0066] The first photovoltaic snow blocking assembly 100a can cooperate with the two adjacent layers of photovoltaic assemblies 220 to improve the stability of the first photovoltaic snow blocking assembly 100a and improve the snow blocking reliability.

[0067] As shown in Figures 3-4 and Figures 6-7As shown, the second photovoltaic snow blocking assembly 100b is arranged outside the outermost photovoltaic assembly 220, and the second photovoltaic snow blocking assembly 100b has at least one crimping portion 12, and the crimping portion 12 is arranged on the edge of the adjacent photovoltaic assembly 220.

[0068] The second photovoltaic snow blocking assembly 100b can cooperate with the adjacent photovoltaic assembly 220 to achieve the snow blocking effect, and is also beneficial to simplify the structure of the second photovoltaic snow blocking assembly 100b, reduce the amount of raw materials and production cost, and prevent the second photovoltaic snow blocking assembly 100b from exceeding the edge of the eave and causing risks such as scratching people or forming ice columns on the exceeding part.

[0069] In one embodiment, as shown in the drawings, Figure 6 The roof has three layers of photovoltaic assemblies 220 from the top end to the eave, and three layers of photovoltaic snow blocking assemblies 100 are arranged correspondingly, wherein the photovoltaic snow blocking assembly 100 close to the eave is the second photovoltaic snow blocking assembly 100b and cooperates with the photovoltaic assembly 220 close to the eave, and the other two photovoltaic snow blocking assemblies 100 are the first photovoltaic snow blocking assemblies 100a and are arranged between the adjacent two layers of photovoltaic assemblies 220.

[0070] Of course, in other embodiments of the present application, the structures of the plurality of photovoltaic snow blocking assemblies 100 of the photovoltaic system 200 can be the same, and each has two crimping portions 12, which can meet the stable installation requirements of the photovoltaic snow blocking assembly 100 at different positions, reduce the number of specifications of the photovoltaic snow blocking assembly 100, facilitate assembly, and improve assembly efficiency.

[0073] The mounting frame 210 mounts the plurality of photovoltaic assemblies 220 on an inclined roof, and the plurality of photovoltaic assemblies 220 are arranged in three layers from the top end to the eave of the roof, and each layer comprises a plurality of photovoltaic assemblies 220 arranged in the horizontal direction. The plurality of photovoltaic snow blocking assemblies 100 are also arranged in three layers from the top end to the eave of the roof, one layer close to the eave is the second photovoltaic snow blocking assembly 100b and is arranged on the lower side of the lowermost photovoltaic assembly 220, and the other two layers away from the eave are the first photovoltaic snow blocking assemblies 100a and are arranged between the two layers of photovoltaic assemblies 220.

[0074] The photovoltaic snow blocking assembly 100 comprises a mounting piece 10 and a snow blocking piece 20.

[0075] In assembly, the mounting piece 11 is attached to the side surface of the photovoltaic assembly 220, and the crimping piece 12 is crimped to the top surface of the photovoltaic assembly 220; the connecting piece 21 is inserted into the accommodating groove 111 through the top groove or the side groove, so that the vertical plate 22 is higher than the surface of the photovoltaic assembly 220; the bolt of the fastener 30 is moved into the cavity 211 through the avoiding port 212, and sequentially passes through the mounting hole 213 of the bottom wall of the cavity 211, the mounting hole 213 of the bottom wall of the accommodating groove 111 and the mounting hole 213 of the mounting frame 210, and is locked with the nut 31, so as to realize the connection and fixation of the snow blocking piece 20, the mounting piece 10 and the mounting frame 210.

[0076] In the above embodiment, the mounting piece 10 is used as a carrier to mount the snow blocking piece 20, the snow blocking piece 20 does not directly contact the photovoltaic assembly 220, and the fastener 30 directly contacts the snow blocking piece 20 and does not directly contact the mounting piece 10, so that the mounting piece 10 can be made of aluminum material with smaller hardness, and the snow blocking piece 20 can be made of steel material with larger hardness, so that the photovoltaic snow blocking assembly 100 has smaller influence on the photovoltaic assembly 220 and is not easy to cause damage to the photovoltaic assembly 220. Meanwhile, the mounting piece 10 and the snow blocking piece 20 are matched, so that the photovoltaic snow blocking assembly 100 can be flexibly arranged at the eaves and the middle position of the roof, and the multilayer photovoltaic snow blocking assembly 100 can form multiple blocking lines, and the impact effect caused by the sliding of the accumulated snow is slowed down, the thin ice is not easy to slide and fall off, and the reliability of the snow blocking structure is ensured.
