[0002] In order to maximize the conversion efficiency of solar panels, the light-receiving surface of solar panels needs to be as perpendicular as possible to the sunlight. Due to the rotation and revolution of the earth, in the Northern Hemisphere, the angle of sunlight irradiation is usually oblique. Placing the solar panels obliquely can make the panels better perpendicular to the sun's rays at different times, thereby improving the efficiency of solar panels.

[0003] However, rainwater easily accumulates along the inclination at the bottom of the solar panel. During sunlight exposure, it is easy to generate the hot spot effect and damage the solar panel.

[0004] The utility model Chinese patent with the publication number CN117155262A introduces a water guiding member for a photovoltaic module. The photovoltaic module includes a photovoltaic panel and a lower frame for fixing the photovoltaic panel. The upper surface of the lower frame is higher than the upper surface of the photovoltaic panel. The water guiding member includes a water guiding net and a water guiding clip buckled on the lower frame. The water guiding clip presses the water guiding net on the lower frame. The upper end of the water guiding clip extends towards the photovoltaic panel side and contacts the photovoltaic panel. The upper end of the water guiding net extends towards the photovoltaic panel side and contacts the photovoltaic panel. Several water guiding grooves are provided on one side of the lower frame close to the water guiding net. Several water absorption mesh holes for increasing its capillary water absorption effect are provided on the water guiding net. The water guiding net surrounds one side of the water guiding groove and forms a drainage channel.

[0005] The problems solved in the above solution can utilize the capillary principle and the siphon principle for drainage at the same time, with better drainage effect and reduced risk of blockage of the drainage structure.

[0006] This application provides another technical solution to solve this technical problem. Summary of the Utility Model

[0007] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a connection structure for photovoltaic modules.

[0008] The above technical purpose of the utility model is achieved through the following technical solutions:

[0009] A photovoltaic module connection structure includes a main bracket. The main bracket is formed with an installation groove for inserting a photovoltaic panel. A pressing plate is slidably arranged in the installation groove. The main bracket is threadedly connected with a bolt for pressing the pressing plate. A plurality of depressions are formed on one side of the installation groove away from the pressing plate. A plurality of flow ports are formed between the photovoltaic panel and the installation groove. A secondary bracket is fixed on the side of the main bracket away from the photovoltaic panel. A diversion port is formed between the main bracket and the secondary bracket. The flow ports and the diversion port are communicated with each other.

[0010] The present utility model is further arranged as follows: A plurality of diversion members are rotatably arranged in the diversion port. The diversion members rotate along with the wind direction. The flow ports are connected with the diversion members through connecting pieces.

[0011] The present utility model is further arranged as follows: The diversion member includes a diversion frame in a ring structure. An annular opening is formed at the center of the diversion frame. One end of the annular opening has a large opening and the other end has a small opening.

The wind will enter from the end of the annular opening with the large opening and flow out from the end of the annular opening with the small opening. By using the change of the opening, the wind speed passing through the annular opening increases, resulting in a decrease in air pressure at the annular opening. Due to the air pressure difference, the wind at the annular opening will pass through the connecting pipe and the flow ports, sucking the water between the main bracket and the photovoltaic panel and the water in the flow ports, so that the water flows into the annular opening and flows away with the wind. Such a design can reduce the accumulated water at the edge of the photovoltaic panel, reduce the probability of hot spot effect generation, and improve the service life of the photovoltaic panel.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] like Figure 1 and Figure 2 As shown, the present application provides a photovoltaic component connection structure, including a main bracket 1, which is formed with a mounting groove 2, and the mounting groove 2 is used for inserting the photovoltaic panel 3. The main bracket 1 mainly supports the edge of the photovoltaic panel 3. After the photovoltaic panel 3 is installed, there is an angle between the mounting plate and the ground, wherein a pressure plate 4 is slidingly arranged in the mounting groove 2, and the pressure plate 4 is located on the side of the photovoltaic panel 3 facing the ground. The pressure plate 4 is fixedly connected to the rubber sheet 5, and the main bracket 1 is threadedly connected with a bolt 6 for pressing the pressure plate 4. By rotating the bolt 6, the pressure plate 4 moves toward the photovoltaic panel 3, so that the photovoltaic panel 3 presses against the side wall of the mounting groove 2 through the rubber sheet 5, thereby ensuring the position stability of the photovoltaic panel 3 in the mounting groove 2, and the rubber sheet 5 will be deformed by the force, which has a buffering and shock-absorbing effect on the photovoltaic panel 3, thereby increasing the protection of the photovoltaic panel 3.

[0023] like Figure 2 and Figure 3As shown in the figure, a secondary bracket 7 is fixed on the side of the main bracket 1 away from the photovoltaic panel 3. A diversion opening 8 is formed between the main bracket 1 and the secondary bracket 7. In this embodiment, the opening direction of the diversion opening 8 has an angle with the plane of the photovoltaic panel 3. A number of diversion members are rotatably arranged in the diversion opening 8, and the a number of diversion members are spaced apart from each other. The diversion member includes a diversion frame 9 in a ring structure. An annular opening is formed at the center of the diversion frame 9. One end of the annular opening has a large opening and the other end has a small opening. The end of the diversion frame 9 with the large opening is rotatably connected to the secondary bracket 7. When the wind blows through the diversion opening 8, the wind will exert a force on the diversion frame 9. Since the diversion frame 9 has an asymmetric shape at both ends, the wind will push the diversion frame 9 to rotate, making the opening direction of the annular opening consistent with the wind direction. The wind will enter through the end of the annular opening with the large opening and flow out from the end of the annular opening with the small opening.

[0024] As Figure 2 and Figure 3 As shown in the figure, a number of depressions are formed on the side of the installation groove 2 away from the pressing plate 4. In this way, a number of flow openings 10 are formed between the photovoltaic panel 3 and the installation groove 2. After rain, some rainwater accumulates along the photovoltaic panel 3 between the photovoltaic panel 3 and the main bracket 1, and some rainwater will flow into the flow openings 10. The main bracket 1 is formed with a first connecting nozzle 11 communicating with the flow opening 10, and the diversion frame 9 is formed with a second connecting nozzle 12 communicating with the annular opening. A connecting member is arranged between the diversion frame 9 and the main bracket 1. The connecting member includes a connecting pipe 13. Both ends of the connecting pipe 13 are respectively communicated with the first connecting nozzle 11 and the second connecting nozzle 12.

[0025] When the wind passes through the annular opening, the cross-section of the annular opening decreases, resulting in an increase in the wind speed flowing out of the annular opening finally. In this way, the air pressure at the annular opening decreases. Due to the air pressure difference, the wind at the annular opening will pass through the connecting pipe 13 and the flow opening 10, attracting the water between the main bracket 1 and the photovoltaic panel 3 and the water in the flow opening 10, making the water flow into the annular opening and flow away with the wind. Such a design can reduce the accumulated water at the edge of the photovoltaic panel 3, reduce the probability of hot spot effect, and improve the service life of the photovoltaic panel 3.

[0026] As Figure 2 and Figure 3 As shown in the figure, the opening direction of the second connecting nozzle 12 inclines towards the end of the annular opening with the small opening. Such a setting can increase the attraction force on the water between the main bracket 1 and the photovoltaic panel 3 and the water in the flow opening 10, improving the effect.

[0027] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
