Description

Technical Field

[0001] The utility model belongs to the related technical field, and particularly relates to a new type of photovoltaic module frame. Background Technique

[0002] With the development of industry, new energy has been paid more and more attention, and the utilization of solar energy has become more and more common. As a green, environmentally friendly and renewable energy, solar energy has been widely promoted. As the most important part of the solar power generation system, the performance and safety efficiency of photovoltaic modules play a crucial role in the entire solar power generation system. At present, in order to protect photovoltaic modules, a new type of photovoltaic module frame is usually arranged around the photovoltaic modules. The new type of photovoltaic module frame is usually formed by alternately enclosing two long frames and two short frames. The edge of the solar cell laminate is accommodated in the notch of the frame, and the photovoltaic module is installed on the bracket through its frame. The frame of the photovoltaic module plays a role in strengthening and sealing the edge of the module. Since the module is not perpendicular to the ground direction, a part of water will be stored between the lower frame of the module and the glass after rain. Without strong light irradiation, this part of rainwater will always exist on the module until it slowly evaporates.

[0003] However, when rainwater falls, it will carry a large amount of impurities in the air, forming solutions with different acids and alkalis, which are corrosive. If rainwater stays between the frame and the glass for a long time, it will continuously corrode the silica gel that seals the module. After corroding the silica gel, it will then corrode the internal EVA, resulting in premature yellowing and attenuation of the photovoltaic module and shortening of its service life.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a novel photovoltaic module frame as Figures 1-4 shown, including two short frames 1 and two long frames 3;

[0025] A short bottom plate 2 is provided at the bottom of the short frame 1, a long bottom plate 4 is provided at the bottom of the long frame 3, a first-level horizontal plate 5 is provided at the top of the short frame 1 and the long frame 3, a first-level vertical plate 6 is provided below the first-level horizontal plate 5, a second-level vertical plate 19 is provided below the first-level vertical plate 6, a second-level horizontal plate 13 is provided on the first-level vertical plate 6, mounting plates 8 are respectively provided on both sides of the short frame 1, two through holes 10 are provided on the mounting plates 8, a long bottom plate 4 is provided at the bottom of the long frame 3, multiple pressing block pieces 17 are provided above the first-level horizontal plate 5 of the long frame 3, screw holes 18 are respectively provided at the bottom of the second-level horizontal plate 13 and above the long bottom plate 4 of the long frame 3, multiple reinforcing ribs 11 are respectively provided at the bottom of the second-level horizontal plate 13 and above the short bottom plate 2 on the short frame 1, and multiple reinforcing edges 22 are provided on the outer sides of the short frame 1 and the long frame 3;

[0026] Multiple drainage grooves 12 are provided on the second-level horizontal plate 13, an inner slope 15 is provided behind the second-level horizontal plate 13, an overflow glue groove 16 is provided at the end of the inner slope 15, an overflow glue groove 16 is also provided at the bottom of the first-level horizontal plate 5, and two pressing convex blocks 20 are provided at the bottom of the first-level horizontal plate 5.

[0027] As Figure 1 and Figure 2 shown, the drainage groove 12 is internally provided with an outward slope, and the drainage groove 12 can drain rainwater and other liquids that penetrate into the long frame 3 and the short frame 1. The cross-section of the overflow glue groove 16 is circular. When injecting glue to install the photovoltaic panel assembly 21, the inner slope 15 can enable the fixing glue to enter the inside of the overflow glue groove 16 through the inner slope 15. The pressing convex blocks 20 are integrally connected to the first-level horizontal plate 5, and the pressing convex blocks 20 can clamp and press the photovoltaic panel assembly 21 installed between the first-level horizontal plate 5 and the second-level horizontal plate 13. Multiple pressing convex blocks 20 can evenly disperse the pressure of the pressing convex blocks 20 on the photovoltaic panel assembly 21.

[0028] As Figure 3 and Figure 4As shown, anti-slip teeth 14 are provided on the secondary cross plate 13. The anti-slip teeth 14 play a role in increasing the friction force on the photovoltaic panel assembly 21, preventing the photovoltaic panel assembly 21 from detaching between the primary cross plate 5 and the secondary cross plate 13. A pair of diagonal plates 7 are respectively provided at the bottom of the short frame 1 and above the short bottom plate 2. A pair of diagonal plates 7 are also respectively provided outside the screw holes 18. The diagonal plates 7 are in a V shape. The diagonal plates 7 are welded to the short frame 1 and the long frame 3. The mounting plate 8 is welded to the short frame 1. The short frame 1 can be fixedly connected to the screw holes 18 on the long frame 3 through the mounting plate 8 and the screws 9.

[0029] Preferably, through the settings of the drainage groove 12 and the anti-slip teeth 14, the drainage groove 12 is provided on the secondary cross plate 13. An outward slope is provided inside the drainage groove 12. When rainwater enters the inside of the primary cross plate 5 and the secondary cross plate 13 through the gap between the photovoltaic panel assembly 21 and the primary cross plate 5, the drainage groove 12 can timely drain the rainwater between the photovoltaic panel assembly 21 and the long and short frames, preventing the rainwater from corroding the silica gel and further corroding the inside of the photovoltaic panel assembly 21, ensuring the service life of the photovoltaic panel assembly 21. Through the setting of the anti-slip teeth 14, after the photovoltaic panel assembly 21 is installed between the primary cross plate 5 and the secondary cross plate 13, the anti-slip teeth 14 can prevent the photovoltaic panel assembly 21 from slipping out between the long and short frames by increasing the friction. At the same time, due to the gaps between the anti-slip teeth 14, when the square photovoltaic panel assembly 21 is installed obliquely, the rainwater can be discharged more quickly through the cooperation of the gaps between the anti-slip teeth 1 and the drainage groove 12, reducing the destructive effect of the rainwater on the inside and outside of the photovoltaic panel assembly 21.

[0030] Preferably, through the settings of the pressing bumps 20, the overflow glue grooves 14, and the inner slopes 15, there are multiple pressing bumps 20 compared with the traditional outer frame of the photovoltaic module. The multiple pressing bumps 20 can disperse the pressing pressure on the photovoltaic panel assembly 21, preventing the pressure of a single pressing bump 20 on the photovoltaic panel assembly 21 from being too concentrated and causing the photovoltaic panel assembly 21 to be crushed. The setting of the overflow glue grooves 14 enables the excess installation glue to be squeezed into the inside of the overflow glue grooves 14 when the photovoltaic panel assembly 21 is installed and injected with glue, preventing the overflow glue from being extruded and covering the surface of the photovoltaic panel assembly 21 and affecting the use of the photovoltaic panel 21. Through the setting of the diagonal plates 7, the diagonal plates 7 can provide support for the inside of the short frame 1 and the long frame 3, preventing the short frame 1 and the long frame 3 from deforming and increasing the strength of the long and short frames.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
