Technical Field

[0001] This utility model relates to the field of photovoltaic frame technology, and in particular to a protective frame for photovoltaic modules with drainage grooves. Background Technology

[0002] In the field of photovoltaic power generation, photovoltaic modules are typically encapsulated and fixed with metal frames and are arranged in large numbers on outdoor sites or rooftops. To improve power generation efficiency and space utilization, adjacent photovoltaic modules are closely spliced ​​together.

[0003] Traditional solar panel frame designs are relatively simple, primarily serving to support and secure the panel. In rainy or snowy weather, rainwater flows down the panel surface, but since the frame is typically higher than the solar panel, rainwater tends to accumulate at the junction of the frame and the panel.

[0004] Water may seep into the back of components or the connection points of the brackets. Long-term immersion can lead to corrosion of connectors, deterioration of electrical insulation performance, and even short circuits in internal circuits, threatening the safety of the power station. Furthermore, if the water cannot be drained quickly, a large amount of water will increase the static load of the entire bracket system. Summary of the Invention

[0005] The purpose of this utility model is to provide a protective frame for photovoltaic modules with drainage grooves. By setting water guiding accessories, it is installed on the lower frame. The water guiding head has a conical structure, which can prevent rainwater from stagnating between the frame and the solar panel, and the rainwater can be quickly discharged downward through the capillary pores, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic module protective frame with a drainage groove, comprising a frame 1, two sets of frame 2 are arranged between the two sets of frame 1, a drainage ditch is installed between the two sets of frame 2, and a water guiding accessory for drainage is installed on the top of the frame 1.

[0018] 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.

[0019] This utility model provides a technical solution: Please see Figures 1 to 4 A protective frame for a photovoltaic module with a drainage groove includes a frame 1, two frames 2 3 are arranged between the two frames 1, a drainage ditch 4 is installed between the two frames 2 3, and a water guiding accessory 2 for drainage is installed on the top of the frame 1. The frame 1 includes a photovoltaic panel frame 101, a slope plate 102 is provided on the top of the photovoltaic panel frame 101, and a support side plate 104 is fixed on the outer surface of the photovoltaic panel frame 101. The water guiding accessory 2 includes an L-shaped bracket 201 that can be detachably installed on the photovoltaic panel frame 101. A drainage component 202 is fixed on the side of the L-shaped bracket 201, and a water guiding head 205 is provided on the other side of the L-shaped bracket 201. The water guiding accessory 2 also includes a fixing plate 203 fixed to the bottom of the L-shaped bracket 201, and a locking bolt 206 is installed inside the fixing plate 203.

[0020] Locking bolts 206 pass through the interior of the support side plate 104 and the fixing plate 203 in sequence. The support side plate 104 is welded and fixed to the photovoltaic panel frame 101. Water guide heads 205 are provided inside the L-shaped bracket 201 and the drainage component 202. The water guide heads 205 are located above the slope plate 102 and are evenly distributed at equal intervals along the side of the L-shaped bracket 201. A flow channel is also provided above the water guide heads 205, the L-shaped bracket 201 and the drainage component 202 to guide the water flow. Capillary pores 204 are provided inside the L-shaped bracket 201 and the drainage component 202.

[0021] By adopting the above technical solution, when installing the two sets of frame 1 and the two sets of frame 3, frame 1 is located on the lower and upper sides of the solar panel, while frame 3 is located on the left and right sides of the solar panel. After rainwater falls on the photovoltaic panel, it will flow along its slope to the side of the slope plate 102 near the lower frame 1 and be discharged downward along the slope plate 102. The rainwater that is trapped can be discharged through the water guide head 205. The water guide head 205 has a conical structure, which can avoid the surface tension of the water flow from preventing the water flow from being unable to be discharged normally. At the same time, under the capillary action, the rainwater can be discharged downward through the capillary holes 204, thereby reducing the rainwater retention at frame 1. The water guide accessory 2 is installed on the lower frame 1. The water guide head 205 has a conical structure, which can prevent the rainwater from being trapped between frame 1 and the solar panel, and the rainwater can be discharged downward quickly through the capillary holes 204.

[0022] Specifically, such as Figure 3 and Figure 5 As shown, the frame 1 also includes an overflow groove 103 inside the photovoltaic panel frame 101, and the overflow groove 103 is located below the slope plate 102.

[0023] The drainage ditch 4 includes a drainage channel 401 sandwiched between two sets of frame 2 3. A connector 402 is welded to the bottom of the drainage channel 401. The connector 402 is fixed above the support side plate 104 by locking bolts 206. The drainage channel 401 has a V-shaped structure.

[0024] Two sets of frame 1 and two sets of frame 2 are connected end to end to form a square photovoltaic module protective frame, and a drainage ditch 4 is installed between the two photovoltaic module protective frames.

[0025] By adopting the above technical solution, the structures of frame 1 and frame 2 are the same and can be spliced ​​together. The splice can be fixed with glue. When the solar panel is installed, the glue can enter the overflow groove 103 to form an effective seal. After the individual solar panel is assembled, the drainage ditch 4 is installed in the gap between the two solar panels. The connector 402 is placed above the support side plate 104 and installed on frame 2 from the bottom of the drainage groove 401 by the locking bolt 206. The V-shaped drainage groove 401 can collect water to the center and prevent rainwater from entering the bottom of the solar panel. Through the drainage groove 4, and the inclination angle of the drainage groove 401 is the same as the inclination angle of the solar panel, rainwater can flow downward along the drainage groove 401 to prevent rainwater from entering the bottom of the solar panel. Since the structures of frame 2 and frame 1 are the same, the support side plate 104 can be freely used with the water guiding accessory 2 and the drainage groove 4 to facilitate drainage of the solar panel.

[0026] Working principle: When installing the two sets of frame 1 and the two sets of frame 3, frame 1 is located on the lower and upper sides of the solar panel, while frame 3 is located on the left and right sides of the solar panel. After rainwater falls on the photovoltaic panel, it will flow along its slope to the slope plate 102 near the lower frame 1 and be discharged downwards along the slope plate 102. The rainwater that is trapped can be discharged through the water guide head 205. The water guide head 205 has a conical structure, which can avoid the surface tension of the water flow from preventing the water flow from being unable to be discharged normally. At the same time, under the capillary action, the rainwater can be discharged downwards through the capillary holes 204, thereby reducing the rainwater retention at frame 1. A V-shaped drainage groove 401 is set between the left and right sides of frame 3, which can collect the water flow to the center and prevent rainwater from entering the lower part of the solar panel. Since the structure of frame 3 and frame 1 is the same, it can be freely matched with the water guide accessory 2 and drainage ditch 4 through the supporting side plate 104.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
