Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic frame technology, and in particular relates to a high-efficiency waterproof photovoltaic frame. Background Technology

[0002] Currently, the industry commonly uses the traditional 45-degree bevel cutting and corner code connection method for assembling photovoltaic frames. This process has the following inherent drawbacks: 1. Sealing Challenges: The end face of the profile after bevel cutting is a bevel, making it difficult to apply effective and continuous sealing materials (such as sealing strips or injection). Usually, it relies on applying sealant at the joints later. The quality is greatly affected by the technical level of the construction personnel, and it is easy to have breaks, air bubbles or incomplete coverage, which can lead to water leakage.

[0003] 2. Structural strength depends on processing precision: The precision requirements for beveled cutting are extremely high. If the cutting angle deviates or there are burrs on the cut, the frame cannot form a perfect 90-degree right angle after assembly, resulting in assembly stress or structural weak areas, which affects the rigidity and torsional performance of the overall frame.

[0004] 3. Meanwhile, the installation of corner brackets usually requires the opening of mounting holes on the inside of the profile, which not only damages the integrity of the profile structure, becoming a potential stress concentration point and water inlet channel, but also adds extra processing steps.

[0005] If an adapter block with an integrated corner bracket structure is set at the connection of two profiles, there is no need to cut the profile at an angle, which can solve the problem of sealing the profile end face and reduce the difficulty of installation. However, due to the relatively complex shape, in order to facilitate production (it is necessary to integrate corner brackets and reserve an area for photovoltaic module installation, so its structure is complex), the adapter is mostly made of plastic, which will cause problems of poor strength and insufficient life at the corners of the frame. In addition, the problem of needing to open holes in the profile to arrange fasteners still exists.

[0006] Therefore, there is an urgent need in this field for an innovative photovoltaic frame connection solution that can balance high strength, high sealing performance, simplified process and reduced cost. Summary of the Invention

[0007] The purpose of this invention is to provide a highly efficient waterproof photovoltaic frame. By integrating corner brackets into right-angle blocks as profile connectors, the profile does not need to be beveled, which facilitates the setting of sealing gaskets and improves the sealing effect of the profile end face. At the same time, the design of the reinforcement solves the problems of creep, aging, or insufficient strength that may occur in pure plastic corner connectors under long-term loads. In conjunction with the design of the concave part and convex edge on the profile, the fasteners of the corner brackets and profile can be transferred to the area between the outer side of the profile and the reinforcement, ensuring that the profile does not need to be drilled, avoiding the problem of strength weakening and water and moisture ingress caused by opening holes, and further improving the waterproof effect of the frame.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a high-efficiency waterproof photovoltaic frame, which includes four profiles and four corner connectors. The four profiles form a rectangular frame, and the corner connectors are set at the connection between two adjacent profiles. The profile includes a hollow rectangular tubular main body, a back plate integrally provided on the outer side of the top edge of the main body, a pressing edge integrally provided at the top of the back plate, a concave part provided on the inner side of the main body, and a convex edge flush with the inner side of the main body at the top and bottom edges of the outer side of the concave part, forming a groove line with a convex shape between the convex edge and the concave part. The corner connector includes a connector and a reinforcing member; The connector includes a right-angled block with a cross-section consistent with that of the profile. An angle bracket edge is integrally provided on both sides of the right-angled block, and a straight groove is provided at the corner of the bottom surface of the right-angled block. The right-angle block is disposed between two adjacent profiles, and the two corner bracket edges are respectively disposed at the inner ends of the main body of the two profiles, with the end face of the profile fitting against the side of the right-angle block; The reinforcement includes an L-shaped plate and fastening bolts; The outer side of the corner of the plate is provided with an installation edge. The angle between the installation edge and the two sides of the plate is 135°. The installation edge is embedded and fixed in the straight groove of the right-angle block. The two sides of the plate are respectively attached to the inner side of the main body of the two adjacent profiles. The upper and lower parts of the plate are provided with stiffening plates, and the two sides of the plate are provided with strip-shaped openings, one end of which extends to the edge of the side of the plate. The fastening bolt includes a T-shaped screw and a nut. The screw head of the T-shaped screw is recessed within the groove. The screw section of the T-shaped screw passes through the gap and the slot formed by the two convex edges. The nut is threaded onto the screw section of the T-shaped screw and presses against the inner side of the side of the plate.

[0009] Furthermore, a component mounting cavity is formed between the top surface of the main body, the back plate, and the pressure edge, and a clearance opening is provided in the upper part of the right-angled block body, which is opposite to the position of the component mounting cavity.

[0010] Furthermore, the screw head of the T-shaped screw is a strip block structure, the width of the screw head of the T-shaped screw is less than the distance between the two convex edges on the profile, and an arc-shaped opening is provided at the diagonal of the screw head of the T-shaped screw.

[0011] Furthermore, a gap is formed between the top of the straight groove and the bottom surface of the relief opening, and the thickness of the gap is consistent with the wall thickness of the main body.

[0012] Furthermore, the portion of the right-angled block that is away from the clearance opening, straight groove, and corner code edge is a solid portion.

[0013] Furthermore, both sides of the right-angled block are reinforced with sealing gaskets, which are located at the connection between the end face of the profile and the right-angled block.

[0014] Furthermore, the apex and bottom of the two outer ends of the two sides of the plate are chamfered, and the chamfers are misaligned with the stiffening plates.

[0015] Furthermore, the height of the corner bracket edge is consistent with the inner height of the main body, and the corner bracket edge is interference-fitted between the concave portion and the outer side of the main body.

[0016] This utility model has the following beneficial effects: This utility model integrates corner brackets as profile connectors using right-angle blocks, ensuring that the profile does not need to be beveled, facilitating the setting of sealing gaskets, improving the sealing effect of the profile end face, avoiding the problem of difficult sealing with beveled surfaces, and greatly improving reliability and waterproof and moisture-proof capabilities. At the same time, through the design of the reinforcement, it solves the problems of creep, aging, or insufficient strength that pure plastic corner connectors may experience under long-term loads. In conjunction with the design of the concave part and convex edge on the profile, it can also transfer the fasteners of the corner bracket and profile to the area between the outer side of the profile and the reinforcement, ensuring that the profile does not need to be drilled, avoiding the problem of strength weakening and water and moisture ingress caused by opening holes, and further improving the waterproof effect of the frame.
