Description

Technical Field

[0001] The utility model relates to the technical field of new energy, and in particular to an anti-slip corner protector for a photovoltaic frame and a photovoltaic component packaging structure. Background Art

[0002] With the widespread adoption of photovoltaic power generation, the environmental conditions facing photovoltaic modules are becoming increasingly harsh, significantly impacting the orderly development of the photovoltaic industry. As a crucial component of solar photovoltaic systems, frames are crucial to the safe operation of photovoltaic modules. Steel frames offer superior mechanical strength, rigidity, and cost advantages over aluminum frames, better meeting the needs of the photovoltaic industry. However, due to their low friction, poor plasticity, and poor anti-slip properties, steel frames cannot be equipped with anti-slip stripes during the photovoltaic module production process, as currently used on mainstream aluminum frames. Consequently, during the actual production, stacking, or movement of photovoltaic modules, steel frames are prone to slipping due to their low friction and high hardness. This increases the difficulty and cost of transporting the steel frames used in photovoltaic modules, and may even lead to damage during transportation. Therefore, ensuring the safety and reliability of steel frames during production, stacking, or transportation has become a key concern for industry professionals.

[0003] In response to the above situation, publication number CN206517361U provides a new type of TPE packaging corner protector for photovoltaic module frames, which is mainly formed by providing protective side panels on both sides of the corners of the photovoltaic module frame, a top panel extending horizontally from the upper edges of the two side panels to protect the top surface of the corners of the photovoltaic module frame, and a bottom panel extending horizontally from the lower edges of the two side panels to protect the bottom surface of the corners of the photovoltaic module frame, and a edging structure for clamping the photovoltaic module frame is provided on the inner edge of the top panel; the packaging corner protector is mainly used to protect the frame to prevent damage to the frame and prevent the packaging corner protector from easily falling off during transportation of the photovoltaic module frame. However, the existing packaging corner protector still cannot solve the problem that the steel frame used for photovoltaic modules is prone to slipping due to low friction during production, stacking or transportation.

[0028] Frame strip 100 ; side wall 110 ; slit 111 ; bottom wall 120 ; bent portion 121 . DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Example

[0031] See also Figure 1 Each photovoltaic frame typically includes several frame bars 100 (e.g., four frame bars 100). These frame bars 100 are connected at the corners to form a square photovoltaic frame, thereby ensuring that the photovoltaic frame encapsulates the sides of the photovoltaic module. Therefore, two adjacent frame bars 100 are connected at the corner. In this embodiment, the frame bars 100 and the photovoltaic frame are preferably made of steel.

[0032] Each frame strip 100 includes a side wall 110 and a bottom wall 120. The fixed end of the bottom wall 120 is bent and connected to the lower edge of the side wall 110, and the free end of the bottom wall 120 is provided with a bent portion 121, which can strengthen the free end of the bottom wall 120.

[0033] In one example of this embodiment, the frame strip 100 may be a frame strip 100 with no gaps in the sidewall. In another example of this embodiment, the frame strip 100 may also be a frame strip 100 with gaps in the sidewall (e.g., Figure 1 As shown), that is, the side wall 110 has a gap 111, which can separate the entire side wall 110 into an upper side wall and a lower side wall. The gap 111 helps to improve the wind resistance resistance of the frame bar 100.

[0034] This embodiment of the invention is a kind of anti-slip corner guard for photovoltaic frame, see Figure 2-7 , comprising a supporting plate 1, a first side plate 2, and a second side plate 3. The first side plate 2 and the second side plate 3 are connected to each other at a corner; both the first side plate 2 and the second side plate 3 are connected to the fixed end of the supporting plate 1. In practice, the anti-slip corner guard can be made of plastic.

[0035] Among them, see Figure 2-3 When in use, the support plate 1 is mounted on the bottom surface of the bottom wall 120 of the two corner-connected frame strips 100. Therefore, the support plate 1 can support and protect the bottom walls 120 of the two corner-connected frame strips 100. The free end of the support plate 1 is also provided with a rimming groove 11. The rimming groove 11 wraps around and engages the free end of the bottom wall 120 of the frame strip 100, allowing the entire anti-slip corner guard to be securely mounted on the frame strip 100. This snap-fit ​​connection makes installation and removal of the frame strip 100 and the anti-slip corner guard more convenient and quick.

[0036] Specifically, the bent portion 121 of the frame strip 100 is snapped into the edging groove 11 so that the entire anti-slip corner guard can be more firmly installed on the frame strip 100, thereby making the overall structure of the anti-slip corner guard and the frame strip 100 more stable after installation.

[0037] Specifically, the number of edging grooves 11 of each anti-slip corner guard is at least two, one of which wraps around and is clamped to the free end of the bottom wall 120 of a frame bar 100 connected to the corner, and correspondingly, the other edging groove 11 also wraps around and is clamped to the free end of the bottom wall 120 of another frame bar 100 connected to the corner; so that the installation structure of the anti-slip corner guard and the two frame bars 100 at the corner of the photovoltaic frame is more stable.

[0038] Further, see Figure 2 、 4 When in use, the first side panel 2 is installed on the outer surface of the side wall 110 of one frame strip 100 adjacent to the corner, and the second side panel 3 is installed on the outer surface of the side wall 110 of the other frame strip 100 adjacent to the corner; in this way, the first side panel 2 and the second side panel 3 can respectively protect the side walls 110 connected at the corners of the two frame strips 100 to prevent the side walls 110 from being damaged.

[0039] Moreover, the first side plate 2 and / or the second side plate 3 are provided with a limiting structure, which is preferably a concave-convex structure 4 (such as Figure 4 When the first side panel 2 is provided with a concave-convex structure 4, the concave-convex structure 4 can be provided at the bottom and / or top of the first side panel 2; similarly, when the second side panel 3 is provided with a concave-convex structure 4, the concave-convex structure 4 can also be provided at the bottom and / or top of the second side panel 3. The specific location of the concave-convex structure 4 can be adjusted accordingly according to actual needs.

[0040] Therefore, the anti-slip corner guard of this embodiment is combined with the concave-convex structure 4 of the first side panel 2 and / or the second side panel 3 on the basis of the supporting plate 1 and the edging groove 11; in this way, when the two frame bars 100 are stacked up and down, the concave-convex structure 4 of one anti-slip corner guard installed on the upper frame bar 100 and the concave-convex structure 4 of the other anti-slip corner guard installed on the lower frame bar 100 are assembled through mutual coordination and splicing, which can limit the displacement of the two frame bars 100 stacked up and down (as well as the two photovoltaic frames stacked up and down), so that the photovoltaic frames stacked up and down form a safe, reliable and stable structure as a whole, thereby avoiding the risk of slipping of the photovoltaic frames during stacking or moving transportation.

[0041] In order to make the two photovoltaic frames stacked up and down form a safer, more reliable and stable structure as a whole, preferably, the first side panel 2 and the second side panel 3 are both provided with a concave-convex structure 4.

[0042] In one example of this embodiment, see Figure 2 、4 The concave-convex structure 4 can be a block 41 or a slot 42, and the block 41 and the slot 42 can engage with each other vertically to achieve the splicing and assembly of the upper and lower anti-slip corner guards. In another example of this embodiment, the concave-convex structure 4 can also be a non-slip wavy convex-concave pattern that matches each other vertically. The convex pattern and the concave pattern fit together vertically to achieve the splicing and assembly of the upper and lower anti-slip corner guards and the anti-slip limit.

[0043] In practice, for multiple photovoltaic frames stacked one above the other (corresponding to multiple frame bars 100 stacked one above the other), some anti-slip corner guards need to be installed on the frame bars 100 at the top of the stack, while some anti-slip corner guards need to be installed on the frame bars 100 at the bottom of the stack, and the remaining anti-slip corner guards need to be installed on the frame bars 100 in the middle of the stack; for these anti-slip corner guards installed at different stacking positions, the concave-convex structures 4 of different anti-slip corner guards can be adjusted accordingly according to actual needs. The specific adjustment plan is as follows:

[0044] Option 1, see Figure 2-4 and Figure 6-7 This anti-slip corner guard needs to be installed on the frame strip 100 in the middle of the stack. For this anti-slip corner guard, the middle of the first side panel 2 is connected to the fixed end of the support panel 1, and the middle of the second side panel 3 is also connected to the fixed end of the support panel 1. Furthermore, the bottom and top of the first side panel 2 are both provided with a concave-convex structure 4, and the bottom and top of the second side panel 3 are also provided with a concave-convex structure 4. This way, the concave-convex structure 4 at the bottom of the upper anti-slip corner guard and the concave-convex structure 4 at the top of the lower anti-slip corner guard can be spliced ​​together.

[0045] Option 2, see Figure 5 This anti-slip corner guard needs to be installed on the frame strip 100 at the bottom of the stack. For this anti-slip corner guard, the lower edge of the first side panel 2 is connected to the fixed end of the carrier board 1, and the lower edge of the second side panel 3 is also connected to the fixed end of the carrier board 1. Furthermore, the tops of the first and second side panels 2, 3 are both provided with a concave-convex structure 4. This allows the concave-convex structure 4 on the bottom of the anti-slip corner guard to interlock with the concave-convex structure 4 on the bottom of the anti-slip corner guard above.

[0046] In option three, this anti-slip corner guard needs to be installed on the frame strip 100 at the top of the stack. For this anti-slip corner guard, the upper edge of the first side panel 2 is connected to the fixed end of the support panel 1, and the upper edge of the second side panel 3 is also connected to the fixed end of the support panel 1. Furthermore, the bottoms of the first and second side panels 2, 3 are both provided with a concave-convex structure 4. This allows the concave-convex structure 4 on the top of the anti-slip corner guard to interlock with the concave-convex structure 4 on the top of the anti-slip corner guard below.

[0047] See also Figure 6-7 The edge of the first side panel 2 is provided with an inclined edge 5 that plugs into the gap 111 of the side wall 110, and the edge of the second side panel 3 is also provided with an inclined edge 5 that plugs into the gap 111 of the side wall 110. In this way, the anti-slip corner guard can better adapt to the frame strip 100 with the gap 111 in the side wall 110; and the inclined edge 5, by plugging into the gap 111, can also play a certain role in limiting and fixing the side wall 110, which can better ensure the stability of the overall structure of the stacked photovoltaic frame and the anti-slip corner guard after installation. Therefore, it can better ensure that the stacked photovoltaic frame is firmly fixed during production, stacking, or transportation, further avoiding the risk of the stacked photovoltaic frame slipping during movement, and further improving the safety and reliability of the stacked photovoltaic frame during movement.

[0048] A photovoltaic module packaging structure of the present embodiment includes several photovoltaic modules stacked up and down, each photovoltaic module corresponding to a photovoltaic frame, so the several photovoltaic modules stacked up and down correspond to several photovoltaic frames stacked up and down; in order to avoid the risk of slipping and damage of these photovoltaic frames stacked up and down during stacking or moving and transportation, anti-slip corner guards are installed at the corners of the photovoltaic frames, and the anti-slip corner guards are the anti-slip corner guards for photovoltaic frames described above in the present embodiment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
