[0020] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figure 1 - Figure 5As shown, the utility model provides a technical solution: a sealing structure of a photovoltaic component frame without an A-side, comprising a frame plate 1, a curved plate 2 is fixedly connected to the top of the frame plate 1, a first glue groove 3 is opened on one side of the curved plate 2, a second glue groove 4 is opened on one side of the curved plate 2, a sealing strip 5 is fixedly connected to the top of the first glue groove 3, a first overflow glue groove 6 is opened on the top of the frame plate 1, and a second overflow glue groove 7 is opened on the top of the frame plate 1. The staff squeezes the special adhesive into the second glue groove 4 and the second overflow glue groove 7, and then fits the photovoltaic panel module to the top of the frame plate 1, so that the photovoltaic panel module squeezes the excess glue in the second overflow glue groove 7 into the first overflow glue groove 6 , so that the glue in the second glue groove 4 is squeezed upward into the first glue groove 3 through the arc-shaped design at the top of the second glue groove 4, and the special adhesive is squeezed to flatten and distribute the contact space between the glue and the frame plate 1 and the arc plate 2. At the same time, the top of the frame plate 1 is constructed with irregular protrusions and depressions, which increases the contact area between the glue and the frame plate 1 and the arc plate 2, and improves the glue bonding effect on the photovoltaic panel module at the top of the frame plate 1. The top of the arc plate 2 is blocked by the sealing strip 5, so that the sealing strip 5 abuts against the top of the photovoltaic panel module, and the connection between the photovoltaic panel module and the arc plate 2 is sealed to prevent dirt from entering the glue coating of the arc plate 2, thereby improving the glue bonding effect on the photovoltaic panel module at the top of the frame plate 1.
[0022] Reference Figure 4 and Figure 5 As shown, in this implementation scheme: two cross frames 8 are fixedly connected to one side of the inner wall of the frame plate 1, and a plurality of vertical plates 9 are fixedly connected to one side of the inner wall of the frame plate 1, and the cross frames 8 and the vertical plates 9 are fixedly connected. Through the fixed connection of the cross frames 8 and the vertical plates 9 arranged inside the frame plate 1, the cross frames 8 and the vertical plates 9 form a frame on one side inside the frame plate 1, which supports and reinforces the load-bearing area of the frame plate 1, increases the overall supporting capacity of the frame plate 1, and makes the frame plate 1 more stable and firm.
[0023] Reference Figure 3 and Figure 5 As shown, in this embodiment: the height of the arc plate 2 is 2CM. Through the characteristic height design of the arc plate 2, the first glue groove 3 and the second glue groove 4 opened on one side of the arc plate 2 can be suitable for use in most photovoltaic panel modules.
[0024] Reference Figure 3 As shown, in this embodiment: the vertical cross-section of the sealing strip 5 is an L-shaped structure. Through the L-shaped structure of the sealing strip 5, the corners of the sealing strip 5 can be flexibly bent, so that the sealing strip 5 can be rolled up to fit tightly against the top of the photovoltaic panel module, thereby increasing the sealing effect of the sealing strip 5 and making the assembly suitable for photovoltaic panel assemblies of different sizes.
[0025] Reference Figure 3As shown, in this embodiment: the corners of the second glue groove 4 are of arc-shaped structure. By designing the corners of the second glue groove 4 to be arc-shaped, when the adhesive is squeezed into the second glue groove 4 and overflows, the rounded corners can squeeze the glue upward and discharge it, so that the excess glue can be discharged from the second glue groove 4 to the outside.
[0026] Reference Figure 5 As shown, in the present embodiment: the horizontal height of the second glue overflow groove 7 is higher than the horizontal height of the first glue overflow groove 6. By designing that the second glue overflow groove 7 is higher than the first glue overflow groove 6, the glue squeezed out of the second glue overflow groove 7 can be discharged into the first glue overflow groove 6, so that the glue can be evenly applied on the top of the frame plate 1, which is more conducive to the spreading of the glue, increases the contact area between the glue and the frame plate 1, and makes the glue bond more firmly.
[0027] Reference Figure 3 As shown, in the present embodiment: the sealing strip 5 is made of rubber material. By adopting the sealing strip 5 made of rubber material, the sealing strip 5 has a certain degree of softness, and fits more closely with the photovoltaic panel assembly after bonding. At the same time, it is not easy to be corroded and aged by long-term wind and sun exposure, so that its service life is greatly improved.
[0028] Working principle: The staff squeezes the special adhesive into the second glue groove 4 and the second overflow glue groove 7, and then fits the photovoltaic panel module with the top of the frame plate 1, so that the photovoltaic panel module squeezes the excess glue in the second overflow glue groove 7 into the first overflow glue groove 6, so that the glue in the second glue groove 4 is squeezed upward into the first glue groove 3 through the arc-shaped design at the top of the second glue groove 4, and the special adhesive is squeezed and distributed to share the contact space between the glue and the frame plate 1 and the arc plate 2. At the same time, the top of the frame plate 1 is irregularly convex and concave, which increases the contact area between the glue and the frame plate 1 and the arc plate 2, and improves the glue on the top of the frame plate 1. The sealing strip 5 is used to block the top of the curved plate 2, so that the sealing strip 5 abuts against the top of the photovoltaic panel module, and the connection between the photovoltaic panel module and the curved plate 2 is sealed to prevent dirt from entering the glue coating of the curved plate 2, thereby improving the glue bonding effect on the photovoltaic panel module at the top of the frame plate 1. The horizontal frame 8 and the vertical plate 9 set inside the frame plate 1 are fixedly connected, so that the horizontal frame 8 and the vertical plate 9 form a frame on one side of the frame plate 1, and the force-bearing area of the frame plate 1 is supported and reinforced, thereby increasing the overall support capacity of the frame plate 1, making the frame plate 1 more stable and firm. The characteristic height design of the curved plate 2 makes the first glue groove 3 and the second glue groove 4 opened on one side of the curved plate 2 suitable for use with most photovoltaic panel modules. The L-shaped structure of the sealing strip 5 allows the corners of the sealing strip 5 to be flexibly bent, so that the sealing strip 5 can be rolled up to fit tightly against the top of the photovoltaic panel module, increasing the sealing plug of the sealing strip 5, so that the assembly can be suitable for photovoltaic panel assemblies of different sizes. By designing the corners of the second glue groove 4 to be arc-shaped, when the adhesive is squeezed into the second glue groove 4 and overflows, the rounded corner can squeeze the glue upward and discharge it, so that the excess glue can be discharged. Water is discharged from the second glue groove 4 to the outside. The design of the second glue overflow groove 7 being higher than the first glue overflow groove 6 allows the glue squeezed out of the second glue overflow groove 7 to be discharged into the first glue overflow groove 6, so that the glue can be evenly applied on the top of the frame plate 1, which is more conducive to the flat spreading of the glue, increases the contact area between the glue and the frame plate 1, and makes the glue bond more firmly. The sealing strip 5 made of rubber material has a certain degree of softness, fits more closely with the bonded photovoltaic panel assembly, and is not easily corroded, aged, or damaged by long-term wind and sun exposure, thereby greatly improving its service life.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
