Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and specifically to a photovoltaic module with hybrid holes and its frame. Background Art

[0002] A photovoltaic module is a key device for converting solar energy into electrical energy. It is composed of multiple solar cells connected in series or parallel and encapsulated in a protective structure composed of glass, backplane, frame, etc. Solar cells generally use semiconductor materials such as silicon. When sunlight shines on the cells, the photon energy is transferred to the electrons in the semiconductor, making them free electrons, thus generating an electric current. Photovoltaic modules have the characteristics of high reliability, long life, and modularity, and can efficiently convert solar energy into direct current electricity. They are widely used in photovoltaic power generation systems, such as distributed power stations, large-scale ground power stations, and household photovoltaic systems, etc., and are the core components for realizing solar photovoltaic power generation.

[0003] However, most of the existing frames of photovoltaic modules have a single structure. During long-term use, they are easily affected by rainfall, causing water accumulation inside the photovoltaic modules and affecting the normal use of the photovoltaic modules. At the same time, the photovoltaic modules are exposed outdoors for a long time and are prone to aging, resulting in the frame being charged. When maintenance personnel repair the photovoltaic modules, there is a risk of electric shock, presenting certain safety hazards. Therefore, we propose a photovoltaic module with hybrid holes and its frame. Summary of the Invention

[0031] Among them, the antireflection layer 105 is a thin film made of silicon dioxide. The antireflection layer 105 adopts a silicon dioxide thin film designed based on the principle of light interference. By precisely controlling the film thickness, the reflection loss of light on the surface of the photovoltaic panel 1 is effectively reduced, enabling more light to enter the interior of the photovoltaic panel 1, creating favorable conditions for the battery cells to absorb photons, significantly improving the utilization efficiency of the photovoltaic panel 1 for solar energy, thereby enhancing the power generation capacity and increasing the electric energy output.

[0032] Among them, the heat dissipation layer 101 adopts an aluminum heat dissipation backplane, which effectively assists the photovoltaic module in heat dissipation operations.

[0033] Among them, it includes a support rod 3. A protective device 2 is provided on the upper surface of the support rod 3. The protective device 2 includes a backing plate 21. The backing plate 21 is fixedly connected to the upper surface of the support rod 3. A supporting block 29 is fixedly connected to the upper surface of the backing plate 21. The supporting block 29 effectively supports the edge of the photovoltaic panel 1, ensuring the stable installation of the photovoltaic panel 1. A side plate 28 is fixedly connected to the upper surface of the backing plate 21. An arc plate 25 is fixedly connected to the upper end of the side plate 28. An installation groove 22 is formed among the arc plate 25, the side plate 28, and the backing plate 21. The water guide holes 10 on the surface of the side plate 28 and the grooves 24 on the surface of the support rod 3 work together to effectively guide the flow direction of liquids such as rainwater and discharge them in a timely manner, preventing the accumulation of liquids on the surface of the photovoltaic panel 1 and protecting the photovoltaic panel 1 from damage caused by water accumulation, extending the service life of the photovoltaic panel 1. The grounding hole 11 is used to connect the grounding wire, safely guiding the static electricity generated by the photovoltaic panel 1 or possible leakage to the ground, comprehensively ensuring the safe operation of the photovoltaic system, reducing safety risks, and providing reliable power supply for users.

The backing plate 21 in the protection device 2 is firmly fixed on the upper surface of the support rod 3, building a stable installation platform for the photovoltaic panel 1. The installation groove 22 composed of the side plate 28 and the arc-shaped plate 25 not only facilitates the adhesive fixation of the photovoltaic panel 1 but also plays a protective role in the edge of the photovoltaic panel 1, reducing damage caused by collisions and scratches.

[0035] Among them, a groove 24 is formed on the surface of the support rod 3, a water guide hole 10 is formed on the surface of the side plate 28, and a grounding hole 11 is formed on the surface of the side plate 28, facilitating the normal use of the device.

[0036] Among them, two symmetrically arranged first convex blocks 23 are fixedly connected to the lower surface of the backing plate 21 to limit the clamping frame 5.

[0037] Among them, a stabilizing device 4 is arranged on the lower surface of the support rod 3. The stabilizing device 4 includes a bottom plate 41, the bottom plate 41 is fixedly connected to the lower surface of the support rod 3, and two symmetrically arranged second convex blocks 42 are fixedly connected to the upper surface of the bottom plate 41, facilitating the limitation of the clamping frame 5 and ensuring the stable installation of the clamping frame 5 on the bottom plate 41.

[0038] Among them, the lower surface of the bottom plate 41 is inserted into the clamping frame 5. A clamping tooth 6 is arranged on the surface of the clamping frame 5, and the clamping tooth 6 abuts against the inner wall of the bottom plate 41. One end of the clamping frame 5 is sleeved with a carrier rod 7, and an installation hole 8 is formed on the surface of the carrier rod 7. Through the friction force between the clamping tooth 6 and the bottom plate 41, the bottom plate 41 can be flexibly fixed at different positions on the clamping frame 5, realizing the precise adjustment of the height and angle of the photovoltaic module to adapt to various installation environments and lighting conditions, improving the installation flexibility and power generation efficiency of the photovoltaic module.

[0039] Among them, the longitudinal section of the clamping frame 5 is in an "L" shape.

[0040] The working principle of the present invention: The photovoltaic panel 1 is the core part for realizing the conversion of solar energy into electrical energy. When sunlight shines on the photovoltaic panel 1, it first passes through the outermost buffer layer 106. The buffer layer 106 mainly plays a role in protecting the internal structure, reducing the direct impact of external environmental factors such as sand and mechanical shock on the fine structure inside the photovoltaic panel 1, and ensuring the stability and durability of the photovoltaic panel 1.

[0041] After the light passes through the buffer layer 106, it reaches the antireflection layer 105. The antireflection layer 105 is made of a thin film of silicon dioxide, and its working principle is based on the interference phenomenon of light. The thickness of the silicon dioxide thin film is designed to be a specific value, so that the reflected light interferes with each other and cancels out after reflecting on the upper and lower surfaces of the thin film, thus greatly reducing the reflection loss of light on the surface of the photovoltaic panel 1 and increasing the intensity of the light entering the interior of the photovoltaic panel 1. More light enters the underlying reinforcement layer 104, passivation layer 103, and cell layer 102, improving the utilization efficiency of the photovoltaic panel 1 for solar energy. The light entering the cell layer 102 is absorbed by the cells, and photons interact with the semiconductor material in the cells to generate electron-hole pairs. The cell layer 102 separates the electrons and holes and guides their directional movement through the internal semiconductor structure and electric field distribution, thereby forming an electric current. The heat dissipation layer 101 uses an aluminum heat dissipation backplane. During the operation of the cells, a certain amount of heat is generated due to energy conversion. The aluminum heat dissipation backplane, with its good thermal conductivity, quickly conducts the heat generated by the cells, preventing the cells from deteriorating due to overheating and ensuring that the cells operate efficiently within an appropriate temperature range.

[0042] The reinforcement layer 104 enhances the overall mechanical strength of the photovoltaic panel 1, protects the internal cells and other functional layers from external damage, and extends the service life of the photovoltaic panel 1.

[0043] The photovoltaic panel 1 is installed on the support rod 3 through the protection device 2. The backing plate 21 is fixed on the upper surface of the support rod 3, providing a stable installation foundation for the photovoltaic panel 1. The side plate 28 and the arc plate 25 are connected to the backing plate 21, jointly forming an installation groove 22. The photovoltaic panel 1 can be placed in the installation groove 22 and fixed by means such as gluing. The arc plate 25 and the side plate 28 can protect the edges of the photovoltaic panel 1, reducing damage caused by collisions, scratches, etc., and also helping to guide the flow of liquids such as rainwater.

[0044] During the installation of the photovoltaic panel 1, when using an adhesive for fixation, the adhesive may overflow. The overflowed adhesive can flow into the glue overflow groove 27, avoiding the adhesive flowing onto the surface of the photovoltaic panel 1 and affecting its performance. At the same time, it is also convenient to clean the excess adhesive, ensuring the cleanliness and stability of the installation of the photovoltaic panel 1.

[0045] The groove 24 opened on the surface of the side plate 28 helps to guide the flow path of liquids such as rainwater on the surface of the side plate 28, avoiding the accumulation of liquids on the surface of the photovoltaic panel 1. The water guide hole 10 discharges the liquid on the surface of the photovoltaic panel 1, preventing water accumulation from damaging the photovoltaic panel 1. The grounding hole 11 is used to connect the grounding wire, safely guiding the static electricity generated by the photovoltaic panel 1 or possible leakage to the ground, ensuring the safe operation of the photovoltaic system.

[0046] Through the frictional force between the engaging teeth 6 and the bottom plate 41, the bottom plate 41 can be fixed at different positions on the clamping frame 5, realizing the adjustment of the height and angle of the photovoltaic module to adapt to different installation environments and lighting conditions. One end of the clamping frame 5 is sleeved on the carrying rod 7, and the mounting holes 8 on the surface of the carrying rod 7 are used to fix the entire photovoltaic module on the external support structure, ensuring the stable operation of the photovoltaic module in the outdoor environment.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
