Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic frame technology, and in particular relates to a low-cost, dust-resistant photovoltaic frame profile. Background Technology

[0002] The existing photovoltaic frame is mainly composed of four profiles. Corner brackets are set between adjacent profiles for reinforcement. The profiles are mainly composed of side A, side B and side C. Side A is mainly used for the assembly of photovoltaic modules. The main body of the photovoltaic module mounting groove is a C-shaped groove structure. Side A will press against the top edge of the glass panel. Therefore, after the frame is assembled, a flange will be formed along the edge of the photovoltaic frame. Due to rainwater washing, dust will accumulate on the bottom of the photovoltaic module, which is the main cause of damage such as shading loss and hot spot effect of photovoltaic panel. This will cause problems such as reduced life of photovoltaic module and poor light reception. Summary of the Invention

[0003] The purpose of this utility model is to provide a low-cost, dust-resistant photovoltaic frame profile. By designing a profile without an A-side and without an installation edge, the material used in the profile can be greatly reduced, the production cost of the profile can be reduced, and the lightweight effect can be achieved. In addition, without the presence of an A-side, rainwater carrying dust will not remain on the photovoltaic module, avoiding the dust accumulation problem and improving the light reception capacity of the photovoltaic module.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a low-cost, dust-resistant photovoltaic frame profile, comprising a profile body and several reinforcing components; The profile body includes a bottom edge portion, and an inner plate portion and an outer plate portion are respectively provided in the middle and outer sides of the top surface of the bottom edge portion. The inner plate portion is higher than the outer plate portion and a beveled edge portion is provided between them. An angle bracket assembly groove is formed between the beveled edge portion, the inner plate portion, the outer plate portion and the bottom edge portion. The inner plate has an outwardly protruding part and an inwardly concave part arranged sequentially from top to bottom at its inner top edge. The reinforcement includes an outer plate, with a pressing edge integrally provided at the top edge of the outer plate via an inclined plate, an elastic edge integrally provided at the bottom edge of the outer plate, an outward protrusion at the top edge of the elastic edge on the side away from the outer plate, an L-shaped mounting edge at the bottom edge of the elastic edge on the side away from the outer plate, and a mounting opening at the transverse edge of the mounting edge. The reinforcement is snapped onto the outside of the profile body by external protrusions. The outer plate, the inclined plate, and the elastic edge cover the outer side of the outer plate, the top surface of the inclined edge, and the bottom surface of the bottom edge, respectively. A photovoltaic panel assembly groove is formed between the pressing edge, the inner plate, and the bottom edge.

[0005] Furthermore, several of the reinforcing members are evenly spaced on the profile body, and the distance between two adjacent reinforcing members is set in the range of 30-50cm.

[0006] Furthermore, an inner fold line is formed on the inner side of the connection between the pressing edge and the inclined plate, and the inner fold line is flush with the inner side of the inner plate.

[0007] Furthermore, the outer protrusion is a right-angled trapezoidal structure or a right-angled triangle structure, and the side of the outer protrusion closest to the outer plate is a vertical side structure that fits against the bottom edge.

[0008] Furthermore, a slit is provided on the inner side of the connection between the elastic edge and the outer plate.

[0009] Furthermore, the width of the reinforcement component is set in the range of 5-7cm.

[0010] This utility model has the following beneficial effects: 1. This utility model, by designing a profile without an A-side and without an installation edge, can greatly reduce the material used in the profile and reduce the production cost of the profile. At the same time, it plays a role in weight reduction. Furthermore, without the presence of an A-side, rainwater carrying dust will not remain on the photovoltaic module, avoiding the problem of dust accumulation and improving the light-receiving capacity of the photovoltaic module.

[0011] 2. This utility model, through the design of the reinforcement components, can add fixing points between the glass plate and the photovoltaic frame, improve the tightness between the photovoltaic module and the photovoltaic frame, avoid problems such as poor stability and delamination caused by the absence of A-side pressing of the glass plate, and improve structural stability and service life.
