Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation, and in particular to a photovoltaic module frame that is resistant to water accumulation and wind vibration. Background Technology

[0002] Currently, photovoltaic module frames are generally higher than the glass panels, leading to water and dust accumulation at the bottom, causing shading, reduced power generation efficiency, and hot spot effects. Additionally, wind vibration can loosen the clamping bolts, posing a safety hazard. While some solutions use water-guiding clips, their effectiveness is limited in light rain, and they may obstruct the solar cells after installation. Furthermore, windproof steel cables require on-site drilling for installation, which can easily damage the solar cells. Therefore, there is an urgent need for an integrated frame structure that combines drainage and wind protection functions. Utility Model Content

[0003] The purpose of this invention is to provide a photovoltaic module frame that is resistant to water accumulation and wind vibration to solve the above-mentioned problems.

[0004] According to one aspect of the present invention, a photovoltaic module frame that is resistant to water accumulation and wind vibration is provided, including a frame body, wherein at least one bevel structure is provided on the lower side of the frame body, and the bevel surface of the bevel structure is inclined at 5°–15° relative to the plane of the photovoltaic module; and multiple reserved bolt holes are pre-drilled on the side of the frame body for fixing windproof steel cables.

[0005] In some embodiments, the edge of the bevel structure is arc-shaped, and the bevel structure extends along the length direction of the lower side of the frame.

[0006] In some embodiments, the bevel structure consists of multiple independent openings evenly distributed on the lower side of the frame.

[0007] In some embodiments, the bevel surface is provided with a hydrophobic coating.

[0008] In some embodiments, the reserved bolt hole is fitted with an anti-loosening threaded sleeve.

[0009] In some embodiments, the frame body includes a first clip and a second clip, which together form a groove for fixing the photovoltaic module.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0011] This application achieves automated production through a bevel structure, incurring no additional cost, and its drainage efficiency is higher than that of water guide clamps, preventing the solar cells from being obstructed; the reserved bolt holes provide installation positions for windproof steel cables, enhancing structural safety and preventing damage to the solar cells from on-site drilling; the hydrophobic coating and anti-loosening threaded sleeve further enhance durability and extend the life of the module.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] refer to Figures 1 to 3 This application provides a photovoltaic module frame that is resistant to water accumulation and wind vibration, including a frame body 1. The frame body 1 has at least one bevel structure 2 on its lower side. The bevel surface 3 of the bevel structure 2 is inclined at 5°–15° relative to the plane of the photovoltaic module. The side of the frame body 1 has a plurality of reserved bolt holes 4 for fixing windproof steel cables.

[0017] In some embodiments, the edge of the bevel structure 2 is arc-shaped, and the bevel structure 2 extends along the lower side length direction of the frame.

[0018] In some embodiments, the bevel structure 2 consists of multiple independent openings evenly distributed on the lower side of the frame.

[0019] In some embodiments, the bevel surface 3 is provided with a hydrophobic coating.

[0020] In some embodiments, the reserved bolt hole 4 is fitted with an anti-loosening threaded sleeve.

[0021] In some embodiments, the frame body 1 includes a first clasp 5 and a second clasp 6, which together form a groove for fixing the photovoltaic module.

[0022] Maximize drainage efficiency:

[0023] 5° lower limit: ensures that rainwater / dust can slide off spontaneously under gravity. Surface tension below 5° makes water droplets easy to remain. 15° upper limit: avoids water splashing onto the upper battery cells due to excessively steep slope. At 10°, the drainage speed can reach 0.5L / min·m (40% higher than the water guide clamp).

[0024] Structural strength assurance:

[0025] When the tilt angle is ≤15°, the impact of beveling on the bending stiffness of the frame is <5%; when it exceeds 15°, the beveling depth needs to be increased, which leads to local stress concentration in the frame and increases the risk of deformation under wind load.

[0026] This application achieves automated production through the bevel structure 2, without additional cost, and the drainage efficiency is higher than that of the water guide clamp, preventing the solar cells from being blocked; the reserved bolt holes 4 provide installation positions for the windproof steel cable, enhancing structural safety and preventing damage to the solar cells from on-site drilling; the hydrophobic coating and anti-loosening threaded sleeve further improve durability and extend the life of the module.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
