Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a photovoltaic module frame that prevents dust accumulation. Background Technology

[0002] With the widespread application of photovoltaic power generation technology, the surface cleaning of photovoltaic modules has received increasing attention. Especially in dusty, sandy, or heavily polluted areas, dust, sand, mud, and other pollutants easily adhere to the module surface, leading to decreased light transmittance and consequently a significant reduction in power generation efficiency. To address this issue, the industry commonly employs rainwater self-cleaning methods. By optimizing the module frame design, rainwater can effectively wash away dust and expel it as it flows over the module surface.

[0003] Currently, to address the above issues, a short-frame spacing without an A-side is generally used. Although a drainage channel structure is introduced to enhance drainage capacity, in practical applications, rainwater still flows at a low velocity when passing through the edge of the module, failing to effectively wash away highly adhesive dust, such as sand and mud, especially at the frame joints where dust easily accumulates. The drainage path is also obstructed, allowing debris such as fallen leaves, dust, and algae to stagnate at the drain outlet, causing localized water accumulation. This further exacerbates the hardening and corrosion of contaminants, affecting the long-term operational stability and power generation performance of the module. Specifically, this manifests as insufficient flushing effect and a high risk of water flow blockage. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a photovoltaic module frame that prevents dust accumulation.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is: a frame for preventing dust accumulation in photovoltaic modules, including a base frame, a side plate fixedly connected to the upper end of the base frame, and the top of the side plate being connected to a first fixing block and a second fixing block respectively. A first flow channel is formed between the first fixing block and the second fixing block, and a second flow channel is formed between adjacent second fixing blocks.

[0006] As a preferred embodiment of this invention, the two first flow channels are symmetrical about the central axis of the frame.

[0007] As a preferred technical solution of this utility model, the ratio of the length of the first flow channel to the length of the frame is 1:5.8~6.

[0008] As a preferred embodiment of this utility model, the ratio of the length of the second flow channel to the length of the first flow channel is 1:1.2~1.3.

[0009] As a preferred embodiment of this utility model, both the first flow channel and the second flow channel are trapezoidal in shape.

[0010] As a preferred technical solution of this utility model, a slot for fixing the side of the photovoltaic module is formed between the first fixing block, the second fixing block and the base frame.

[0011] As a preferred technical solution of this utility model, the first fixing block and the second fixing block have overflow grooves on their inner sides, and the bottom front side of the first fixing block and the second fixing block are flush with the upper edge of the side plate.

[0012] As a preferred embodiment of this utility model, the left side of the base frame has a cavity for installing corner brackets.

[0013] As a preferred embodiment of this utility model, a fixing plate is connected to the right side of the base frame.

[0014] Because of the structure adopted in this utility model, the synergistic effect of the first flow channel 4 and the second flow channel 5 effectively solves the problems of dust accumulation, poor drainage, and complex process in the existing short frame design. It has good engineering practicality and market application prospects, and is of great significance for improving the power generation efficiency and maintenance convenience of photovoltaic modules.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-3As shown, this utility model discloses a dust-proof photovoltaic module frame, characterized by: a base frame 1, with a side plate fixedly connected to the upper end of the base frame 1. The top of the side plate is connected to a first fixing block 2 and a second fixing block 3, respectively. A first flow channel 4 is formed between the first fixing block 2 and the second fixing block 3, and a second flow channel 5 is formed between adjacent second fixing blocks 3. The base frame 1, side plate, first fixing block 2, and second fixing block 3 are integrally formed. Through the synergistic effect of the first flow channel 4 and the second flow channel 5, the rainwater flow rate can be increased, thereby enhancing the flushing ability against adhesive dust, ensuring that dust is completely removed from the module surface, improving the cleaning effect, preventing fallen leaves, dust, algae, and other debris from accumulating at the drain outlet, reducing the risk of blockage, and ensuring the long-term smoothness and stability of the drainage system.

[0021] Furthermore, in this invention, the two first flow channels 4 are symmetrical about the central axis of the frame. The symmetrical first flow channels 4 are aesthetically pleasing.

[0022] Furthermore, in this invention, the ratio of the length of the first flow channel 4 to the length of the frame is 1:5.8~6, and the ratio of the length of the second flow channel 5 to the length of the first flow channel 4 is 1:1.2~1.3. For example, if the short side length of the photovoltaic module is 1303mm, the length of the first flow channel 4 is 220mm, and the length of the second flow channel 5 is 175mm, the optimized design of the flow channel structure significantly increases the drainage cross-sectional area and improves the rainwater flow rate, thereby enhancing the ability to flush away adhesive dust, ensuring that dust is completely removed from the module surface, and improving the cleaning effect.

[0023] Furthermore, in this invention, both the first flow channel 4 and the second flow channel 5 are trapezoidal in shape. Optimizing the flow channel angle prevents debris from accumulating at the drain outlet, reduces the risk of blockage, and ensures the long-term smooth operation and stability of the drainage system.

[0024] Furthermore, in this invention, a slot 6 for fixing the side of the photovoltaic module is formed between the first fixing block 2, the second fixing block 3, and the base frame 1. An overflow groove 8 is formed on the inner side of the first fixing block 2 and the second fixing block 3. The bottom front end of the first fixing block 2 and the second fixing block 3 is flush with the upper edge of the side plate. After the edge of the photovoltaic module is inserted into the slot 6, the bottom front end of the first fixing block 2 and the second fixing block 3 abuts against the upper surface of the photovoltaic module, thus providing a fixing function.

[0025] Furthermore, the base frame 1 has a cavity 7 on its left side for mounting corner brackets. The corner brackets are installed in the cavity 7 for frame assembly, and the photovoltaic modules are fixed to the bracket via the horizontally extending cavity 7 using clamps or bolts.

[0026] Furthermore, a fixing plate 9 is connected to the right side of the base frame 1. The fixing plate 9 extends inward from the base frame 1, which helps to improve the load-bearing capacity and installation stability.
