Description

Technical Field

[0001] This utility model relates to the field of anti-dust accumulation component frame technology, and in particular to an anti-dust accumulation component frame structure. Background Technology

[0002] The anti-dust accumulation module frame structure is a support device for installing photovoltaic modules. After the photovoltaic modules are installed, after a period of exposure to the sun and dust accumulation, due to rain and tilt, a dust accumulation band will form at the bottom of the module. The module frame is about 3mm higher than the module glass surface. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of the anti-dust accumulation module frame structure.

[0003] The existing anti-dust accumulation component frame structure has certain drawbacks in use. Existing patent application CN217721115U discloses a component frame without an A-side. As described in the patent, the entire component (long and short sides) does not have an A-side (the front of the component frame). However, during installation, rubber pads are required to buffer mechanical contact stress, which brings certain adverse effects to the actual use process. Therefore, we propose an anti-dust accumulation component frame structure. Utility Model Content

[0004] Technical problem solved: To address the shortcomings of existing technologies, this utility model provides a frame structure for an anti-dust-accumulation component. The barbed structure slows down the upward overflow of silicone within a certain range, while the inverted hooks facilitate the continued upward flow of silicone and increase the contact surface area between the silicone and the frame, increasing the shear force of the silicone between the upper and lower parts and enhancing the negative pressure strength of the component. The overflow groove structure increases the contact area of ​​the silicone and ensures sufficient contact of the internal silicone. The 3° inclined surface of the short frame prevents wastewater residue. In photovoltaic systems with a built-in tilt angle, this design minimizes the retention of wastewater in the gaps between the laminate and the frame, effectively solving the problems in the background technology.

[0005] Technical Solution: To achieve the above objectives, the technical solution adopted by this utility model is as follows: a frame structure for an anti-dust accumulation component, comprising a frame body, an integrally formed short frame structure at the upper end of the frame body, an integrally formed short side groove structure, a barb structure, and an inverted hook structure on the inner side of the short side of the short frame structure, the barb structure and the inverted hook structure being located at the upper and lower front ends of the short side groove structure, an overflow groove structure being provided on the right side of the short frame structure, a sealant being provided on the inner side of the short frame structure, an integrally formed inclined structure on the top of the short frame structure, a laminate structure being installed on the short frame structure, and a rubber strip being positioned inside the short side groove structure on the inner side of the short frame structure.

[0006] Preferably, the short frame structure has a fixing clip inside, a positioning rod is positioned on the side of the fixing clip, a limiting clip is positioned at the end of the positioning rod, a limiting groove is opened on the side of the laminate structure corresponding to the position of the limiting clip, and a sealing ring gasket is positioned between the limiting clip and the limiting groove.

[0007] Preferably, the frame body and the short frame structure are integrally formed by die casting, and the short frame structure is integrally formed with the short side groove structure, barb structure, inverted hook structure, inclined surface structure and overflow groove structure by die casting.

[0008] Preferably, the sealant is filled and positioned at the position of the overflow groove structure and the short side groove structure inside the short frame structure, and the laminate structure is sealed and positioned with sealant during installation with the short frame structure.

[0009] Preferably, a rubber strip is added to the inner side of the short side groove structure, and the length and angle of the rubber strip are consistent with those of the short side groove structure. When the laminate structure is positioned with the short frame structure, the rubber strip is slowly squeezed, and the rubber strip is squeezed upward and sealed horizontally with the laminate structure at the top.

[0010] Preferably, the fixing clip, positioning rod and limiting clip are integrally formed by casting. The limiting clip is engaged inside the limiting groove and sealed by a sealing ring gasket, and limits the structure of the laminate.

[0011] Beneficial Effects: Compared with the prior art, this utility model provides a frame structure for an anti-dust-accumulation component, which has the following beneficial effects: The barbed structure slows down the upward overflow of silicone within a certain range, the inverted hooks facilitate the continued upward flow of silicone, and increase the contact surface area between silicone and the frame, increase the shear force of silicone between the upper and lower parts, enhance the negative pressure strength of the component, the overflow groove structure increases the contact area of ​​silicone and ensures full contact of internal silicone, and the 3° inclined surface of the short frame prevents sewage residue. In photovoltaic systems with a built-in tilt angle, it minimizes the retention of sewage in the gap between the laminate and the frame. The entire anti-dust-accumulation component frame structure is simple in structure, easy to operate, and has a better effect than traditional methods. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1-4As shown, a dust-prevention component frame structure includes a frame body 1. A short frame structure 2 is integrally formed on the upper end of the frame body 1. A short side groove structure 3, a barb structure 5, and an inverted hook structure 6 are integrally formed on the inner side of the short side of the short frame structure 2. The barb structure 5 and the inverted hook structure 6 are located above and below the front end of the short side groove structure 3. An overflow groove structure 8 is provided on the right side of the short frame structure 2. Sealant 7 is provided on the inner side of the short frame structure 2. A sloping structure 4 is integrally formed on the top of the short frame structure 2. A layer of [unclear - possibly a product name or material] is installed on the short frame structure 2. The pressure structure 9 and the short frame structure 2 have a rubber strip 11 positioned inside the short side groove structure 3. The barbed structure slows down the upward overflow of silicone within a certain range, and the inverted hook facilitates the continued upward flow of silicone and increases the contact surface area between silicone and the frame, increases the shear force of silicone between the upper and lower parts, and enhances the negative pressure strength of the module. The overflow groove structure increases the contact area of ​​silicone and ensures full contact of internal silicone. The 3° inclined surface of the short frame is to prevent sewage residue. In photovoltaic systems with a built-in tilt angle, sewage should be avoided from accumulating in the gap between the laminate and the frame as much as possible.

[0021] Furthermore, the short frame structure 2 has a fixing clip 10 for internal positioning, a positioning rod 12 for side positioning of the fixing clip 10, a limiting clip 14 for end positioning of the positioning rod 12, a limiting groove 13 for side positioning of the laminate structure 9 corresponding to the position of the limiting clip 14, and a sealing ring gasket 15 for positioning between the limiting clip 14 and the limiting groove 13.

[0022] Furthermore, the frame body 1 and the short frame structure 2 are integrally formed by die casting, and the short frame structure 2 is integrally formed with the short side groove structure 3, barb structure 5, inverted hook structure 6, inclined surface structure 4 and overflow groove structure 8 by die casting.

[0023] Furthermore, the sealant 7 fills and positions the overflow groove structure 8 and the short side groove structure 3 inside the short frame structure 2, and the laminate structure 9 is sealed and positioned with the short frame structure 2 during installation using the sealant 7.

[0024] Furthermore, a rubber strip 11 is added to the inner side of the short side groove structure 3, and the rubber strip 11 is consistent with the short side length and angle of the short side groove structure 3. When the laminate structure 9 is positioned with the short side frame structure 2, the rubber strip 11 is slowly squeezed, and the rubber strip 11 will be squeezed upward and sealed with the laminate structure 9 at the top while remaining horizontal.

[0025] Furthermore, the fixing clip 10, the positioning rod 12 and the limiting clip 14 are integrally formed by casting. The limiting clip 14 is engaged inside the limiting groove 13 and sealed by the sealing ring gasket 15, and limits the laminate structure 9.

[0026] Working Principle: This utility model includes a frame body 1, a short frame structure 2, a short side groove structure 3, a bevel structure 4, a barb structure 5, an inverted hook structure 6, sealant 7, an overflow groove structure 8, a laminate structure 9, a fixing clip 10, a rubber strip 11, a positioning rod 12, a limiting groove 13, a limiting clip 14, and a sealing ring gasket 15. The short side is designed without an A-side, with a 3° bevel of approximately 3.5mm-5mm at the top edge. This internal space is used to place the sealant, ensuring a certain thickness. The barb structure slows down the upward overflow of silicone within a certain range. The inverted hook facilitates the continued upward flow of silicone and increases the contact surface area between the silicone and the frame, increasing the shear force of the silicone between the upper and lower parts and enhancing the negative pressure strength of the component. The overflow groove structure increases the contact area of ​​the silicone and ensures sufficient contact of the internal silicone. The 3° bevel of the short frame prevents wastewater residue. In photovoltaic systems with a built-in tilt angle, it is necessary to minimize the retention of wastewater in the gap between the laminate and the frame.

[0027] The black filler represents the silicone being applied to the frame. The silicone is mainly concentrated at the bottom of the glass groove in the frame, which allows the silicone to easily overflow to both sides during frame assembly and reduces the probability of silicone overflowing upwards.

[0028] After the short frame, silicone, and laminate are fully assembled, they will present three states: Left image---the laminate is in direct contact with the frame, and the silicone cannot overflow upwards; Middle image---there is a gap of about 1mm between the laminate and the frame, and after the silicone overflows upwards, it forms a slope after cleaning, which facilitates the drainage of wastewater; Right image---there is a gap of about 1mm between the laminate and the frame, and after the silicone overflows upwards, it does not completely extend beyond the glass surface, forming a very small groove. The long side is cut at 45° at both ends, and the distance from the laminate to the edge (short side) is about 3.5-5mm. The module is about 3mm longer than the standard module in length. To ensure a more secure design and assembly structure, and to prevent increased difficulty in controlling the amount of silicone and address glass size tolerance issues, a rubber strip (EPDM) is added to the short side groove. This strip is the same length and angle as the short side. During the framing process, the laminate gradually approaches the frame (inner side of the short side). As the rubber strip is slowly squeezed, it is gradually pushed upwards. After framing, the top of the rubber strip is basically level with the frame, achieving a sealing effect.
