Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anti-skid corner guards, and specifically relates to an anti-skid corner guard for photovoltaic component stacking and a photovoltaic component stacking bag formed by stacking photovoltaic components using the anti-skid corner guard. Background Art
[0002] Referring to the authorization announcement number CN117013942B, the frame of the existing photovoltaic module is provided with side panels, a top panel and a bottom panel, a load-bearing portion is provided in the side panel, and a notch is provided between the load-bearing portion and the top panel, and the notch is used to connect the laminate. During transportation, multiple modules are laid flat and stacked, and due to the low friction coefficient between the module frames, the modules are prone to misalignment or even scattering.
[0003] Based on this, conventional aluminum frames often have transverse grooves on the top and bottom surfaces of the frame, such as the tooth-shaped structure in the prior art, to reduce the occurrence of component dislocation and scattering to a certain extent. As for steel frames and composite frames, the former has a cold-bent frame structure, and the latter has a low friction coefficient of the surface coating, so these two frames still have problems of dislocation and scattering during actual transportation.
[0004] For steel frames and composite frames, in the actual production process, frame manufacturers often glue anti-slip foam on the frames. However, this measure can only be used once, and its anti-slip effect is limited by the adhesion of the glue and has poor reliability. In addition, it is easy to leave offset marks on the frame, affecting the appearance of the component. Utility Model Content
[0005] The utility model aims to overcome the deficiencies in the prior art and provide an anti-slip corner protector for photovoltaic module stacking.
[0006] To achieve the above objectives, the utility model discloses an anti-slip corner guard for stacking photovoltaic modules, comprising a substrate, a first limiting portion and a second limiting portion. The width of the substrate is not less than the width of the bottom plate of the photovoltaic module frame. The first limiting portion is located on one side of the width direction of the substrate and extends upward, and is used to cooperate with the side plate of the photovoltaic module frame. The second limiting portion is located on the other side of the width direction of the substrate and extends downward, and is used to cooperate with the free end of the bottom plate.
[0007] Preferably, the angle between the first limiting portion and the substrate is 85° to 95°.
[0008] Preferably, the second limiting portion includes a connecting section and a pressing section, one end of the connecting section is connected to the substrate, and the other end is connected to the pressing section, which is used to limit the free end of the bottom plate, and the pressing section is used to press and cooperate with the bearing part of the photovoltaic component frame.
[0009] Further preferably, the connecting section is L-shaped.
[0010] Preferably, the second limiting portion is hook-shaped.
[0011] Further preferably, the second limiting portion is in a straight hook shape or a curved hook shape.
[0012] Preferably, in a direction perpendicular to the base plate, the projection of the anti-slip corner guard is in the shape of an angle, and the angle of the angle is 85° to 95°.
[0013] Preferably, the corners of the anti-slip corner guard are rounded or covered with soft protective parts.
[0014] Preferably, the anti-slip corner guard is formed by bending.
[0015] The utility model also provides a photovoltaic component stacking bag formed by stacking photovoltaic components using the above-mentioned anti-slip corner guards.
[0016] A photovoltaic module stacking bag comprises a photovoltaic module and an anti-slip corner guard. There are multiple photovoltaic modules, which are stacked and the anti-slip corner guard is installed between two adjacent photovoltaic modules. The anti-slip corner guard is any of the above-mentioned anti-slip corner guards.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] When stacking photovoltaic modules, the substrate of the anti-skid corner guard is placed on the bottom plate of the photovoltaic module frame, and the second limiting part is matched with the free end of the bottom plate to prevent the substrate from moving outward and causing the problem of falling off; when stacking the next photovoltaic module, the photovoltaic module is stacked on the previous photovoltaic module, which presses the substrate of the anti-skid corner guard and is located inside the first limiting part. The first limiting part can limit the movement of the photovoltaic module, thereby avoiding the problem of misalignment and scattering. In actual use, the anti-skid corner guard is installed on each side of the photovoltaic module frame to ensure that the photovoltaic modules can be stacked securely.
[0019] By using anti-slip corner guards to assist in stacking photovoltaic modules, the appearance and quality of the photovoltaic module frames are guaranteed, avoiding the problem of damaging the frame appearance by using the method of gluing anti-slip foam.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0031] Example 1
[0032] The anti-slip corner guard provided in this embodiment is used in the stacking process of the photovoltaic module 1, wherein, see Figure 1-Figure 2 The frame 11 of the existing photovoltaic module 1 includes a side plate 111, a top plate 112 and a bottom plate 113. A bearing portion 114 is provided in the side plate 111. A notch 115 is provided between the bearing portion 114 and the top plate 112. The notch 115 is used to connect the laminate 12. A reinforcing flange 1131 is provided at the free end of the bottom plate 113. The frame structure is an existing structure and will not be described in detail.
[0033] In order to prevent the photovoltaic modules from scattering during transportation, this embodiment provides an anti-slip corner guard for stacking photovoltaic modules. Figure 3-Figure 5The anti-slip corner guard includes a substrate 3, a first limiting portion 4 and a second limiting portion 5. The width of the substrate 3 is not less than the width of the bottom plate 113 of the photovoltaic module frame, thereby ensuring that the stacking of multiple photovoltaic modules is not affected by the two limiting portions. The first limiting portion 4 is located on one side of the width direction of the substrate 3 and extends upward, and is used to limit the side plate 111 of the photovoltaic module frame, so as to limit the stacked photovoltaic modules and avoid the problem of misalignment and scattering. The second limiting portion 5 is located on the other side of the width direction of the substrate 3 and extends downward, and is used to limit the free end of the bottom plate 113 to prevent the substrate 3 from falling off the bottom plate 113 of the frame.
[0034] During the stacking process, the substrate 3 with anti-skid corner guards is placed on the bottom plate 113 of the photovoltaic module frame, and the second limiting portion 5 is limited to cooperate with the free end of the bottom plate 113 to prevent the substrate 3 from moving outward and causing the problem of falling off; when stacking the next photovoltaic module, the photovoltaic module is stacked on the previous photovoltaic module, and presses the substrate 3 with anti-skid corner guards and is located inside the first limiting portion 4. The first limiting portion 4 can limit the movement of the photovoltaic module, thereby avoiding the problem of misalignment and scattering. In actual use, the anti-skid corner guards are installed on each side of the photovoltaic module frame to ensure that the photovoltaic modules can be stacked securely. By using anti-skid corner guards to assist in stacking photovoltaic modules, the appearance and quality of the frame are guaranteed, and the problem of damaging the appearance of the frame by bonding anti-skid foam is avoided. The anti-skid corner guards can be recycled and reused after use, which reduces costs compared to processing transverse grooves on each frame.
[0035] In this embodiment, the width of the base plate 3 is slightly larger than the width of the frame bottom plate 113. The above width setting can not only avoid the interference between the two limit parts on the base plate 3 and the frame due to the short length, which affects the stacking, but also ensure the compact structure and avoid the length being too long and occupying space, affecting the transportation efficiency. The preferred width of the base plate 3 is 31 mm, and of course it can also be designed to other sizes according to the frame size, which will not be repeated here.
[0036] In this embodiment, the angle between the first limit portion 4 and the substrate 3 is 85° to 95°, which can ensure that the photovoltaic modules stacked on the anti-slip corners will not be scattered, and at the same time ensure a compact structure to avoid occupying a large space and affecting transportation efficiency. Preferably, the first limit portion 4 is perpendicular to the substrate 3, and its height is not greater than the height of the side plate 111. While ensuring that its mechanical properties meet the requirements, its height can be appropriately reduced, which can reduce costs. The preferred height is 5-30 mm.
[0037] In this embodiment, see Figure 3The second limiting portion 5 includes a connecting section 51 and a pressing section 52. One end of the connecting section 51 is connected to the substrate 3, and the other end is connected to the pressing section 52. The pressing section 52 is arranged in the vertical direction and is used to press and cooperate with the bearing portion 114 of the photovoltaic module frame. During assembly, there is a certain assembly gap or contact between the pressing section 52 and the frame bearing portion 114. During transportation, if two adjacent photovoltaic modules are slightly offset, the force point of the photovoltaic module located below moves toward the free end of the frame bottom plate 113. At this time, the pressing section 52 presses the bearing portion 114, thereby assisting the bottom plate 113 of the photovoltaic module frame below to support the photovoltaic module above, thereby reducing the mechanical performance requirements for the bottom plate 113.
[0038] Among them, the height of the pressure section 52 is slightly smaller than the height of the bearing part 114 of the photovoltaic module frame. Preferably, for a 30mm high pressure-bearing part (for double-glass modules), its height is 0-25mm, and for a 35mm high pressure-bearing part (for single-glass modules), its height is 0-30mm.
[0039] The connecting section 51 is L-shaped, which is easy to process and has good mechanical properties. Figure 2-Figure 3 As shown, the connecting section 51 includes a vertical section 511 and a transverse section 512. The two ends of the vertical section 511 are respectively connected to the substrate 3 and one end of the transverse section 512. The other end of the transverse section 512 is connected to the pressing section 52. The height of the vertical section 511 is not less than the height of the photovoltaic module bottom plate 113.
[0040] As another optional method, the second limiting portion 5 may be hook-shaped, and the hook-shaped second limiting portion 5 may be limitedly matched with the reinforced flange 1131 of the frame bottom plate 113 (see Figure 6 ). See Figure 4-Figure 5 It should be noted that the hook-shaped second position-limiting portion 5 is simpler in structure than the above-mentioned second position-limiting portion 5, but it cannot assist the frame bottom plate 113 in supporting the photovoltaic module located above. Therefore, the second position-limiting portion 5 with this structure has certain mechanical performance requirements for the frame bottom plate 113.
[0041] In this embodiment, see Figure 7 In the direction perpendicular to the substrate 3, the projection of the anti-slip corner guard is in an angle shape, and the angle of the angle is 85° to 95°. With this design, the anti-slip corner guard can be used for the corners of the frame. When in use, two anti-slip corner guards are installed on two opposite corners of the frame, so that the four sides of the frame can be fixed, which is beneficial to saving packaging time and improving packaging efficiency.
[0042] Since the corners of the frame are generally 90°, the angle of the above-mentioned included angle is 90°, which can make the anti-slip corner guard more suitable for the frame.
[0043] In this embodiment, the corners of the anti-slip corner guard are rounded or covered with soft protective parts, which can prevent scratches on the staff. The soft protective parts include but are not limited to foam, silicone, and rubber.
[0044] In this embodiment, the anti-skid corner guard is formed by bending, and the processing is simple. If the anti-skid corner guard has two intersecting base plates 3, one anti-skid corner guard can be processed separately, and then the two anti-skid corner guards can be connected together by a fixed connection.
[0045] In this embodiment, the material of the anti-slip corner guard is a rigid material such as metal, including but not limited to aluminum, iron, steel, alloy, etc.
[0046] Example 2
[0047] A photovoltaic module stacking support bag comprises a photovoltaic module and an anti-skid corner guard. There are multiple photovoltaic modules, which are stacked and an anti-skid corner guard is installed between two adjacent photovoltaic modules. The anti-skid corner guard is the one used in Example 1.
[0048] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
