Furthermore, during heavy rainfall, rainwater can easily overflow, or in northern winters with freezing rain, it can freeze and clog the channels, causing leaks. Utility Model Content

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a conveniently installed photovoltaic module frame water guiding device and photovoltaic system, thereby solving the problem of inconvenient installation of existing water guiding devices.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] First, a conveniently installed photovoltaic module frame water guiding device is provided, including a water guiding channel installed between two adjacent photovoltaic module frames.

[0014] In addition, a photovoltaic system is provided, including the aforementioned water guiding device.

[0015] The present invention adopts the above technical solution and has the following beneficial effects:

[0016] 1. Instead of the conventional under-mount installation, the water guide channel is installed between the frames of two adjacent photovoltaic modules, allowing for installation above the photovoltaic modules. The water guide channel has a first fixed edge on its first side of opening, which is fastened to edge A of the first photovoltaic module frame. The water guide channel also has a first snap-fit ​​on its second side of opening, and a first slot on the upper part of the second photovoltaic module frame. The snap-fit ​​engages with the first slot. This combination of fasteners on one side ensures reliable fixation, while snap-fit ​​on the other side facilitates quick installation.

[0017] 2. The water channel includes a top water channel with its bottom lower than side A of the photovoltaic module frame, and at least two layers of leak-proof water channels located below the top water channel and arranged in layers along the height direction. In this way, normal rainwater is discharged through the top water channel, while when the rainfall is heavy, it will leak into the lower multi-layer leak-proof water channels and be discharged, preventing rainwater from overflowing in the event of heavy rainfall.

[0018] 3. At least two layers of leak-proof water channels are elastically engaged between the frames of two adjacent photovoltaic modules, and the two side walls of the leak-proof water channels extend obliquely upward, thus having greater elasticity. This allows the two sides of the opening of the leak-proof water channel to be engaged into the grooves on the B side of the two photovoltaic module frames, but it is not sealed, but has a certain leakage gap, thereby further improving the installation reliability of the water channel. Moreover, this structure makes it convenient for the upper water channel to leak into the lower leak-proof water channel when the water volume is large.

[0019] 4. The first slot protrudes from the upper part of the second side photovoltaic module frame B. An L-shaped bending structure is provided between the first buckle and the second side of the top water tank opening. Therefore, when the first buckle is installed, the first buckle is inserted into the first slot by means of the elasticity of the L-shaped bending structure.

[0020] 5. A waterproof gasket is provided between the first fixed edge and the first side photovoltaic module frame A to prevent water leakage; the fastener is a fastening screw, and the first side photovoltaic module frame A is provided with a threaded hole for connecting with the fastening screw, thus facilitating the fastening screw fixation.

[0021] 6. A pressure plate bolt assembly connects the frames of two adjacent photovoltaic modules, and the pressure plate bolt assembly fixes them to the purlin. The pressure plate bolt assembly includes a pressure plate and a U-bolt. The U-bolt connects the purlin and the pressure plate, and the pressure plate connects to the frames of the photovoltaic modules on both sides. Therefore, it facilitates the installation of photovoltaic modules on the purlin.

[0022] 7. Different connection structures are used between the pressure plate and the first-side photovoltaic module frame and the second-side photovoltaic module frame. The first-side photovoltaic module frame has a second buckle at its bottom B-side, and the pressure plate has a second slot on its first side; the second buckle engages with the second slot. The second-side photovoltaic module frame has a slot at its bottom B-side, and the pressure plate has a protruding edge on its second side; the protruding edge is pressed into the slot. This allows for the installation of the second-side photovoltaic module first, with the pressure plate bolt assembly securing the pressure plate and pressing the protruding edge into the slot. Then, the first-side photovoltaic module is installed, and the second buckle engages with the second slot, facilitating the sequential installation of photovoltaic modules from the second direction to the first direction.

[0035] Reference Figures 1 to 4 As shown, the photovoltaic module includes a photovoltaic panel 2 and a frame 1. This embodiment relates to a water guiding device for the photovoltaic module frame, including a water guiding channel 3 installed between two adjacent photovoltaic module frames 1. The first side of the opening of the water guiding channel 3 is provided with a first fixing edge 311, which is fixed to edge A of the first photovoltaic module frame by fasteners. The second side of the opening of the water guiding channel 3 is provided with a first buckle 35, and the upper part of the second photovoltaic module frame is provided with a first slot 11. The first buckle 35 engages with the first slot 11. In this way, one side is fixed with fasteners to ensure reliable fixation, and the other side is fixed with buckles for easy and quick installation. Therefore, this combined installation method is convenient and reduces construction difficulty.

[0036] In some embodiments, the water channel 3 includes a top water channel 31 with its bottom lower than the edge A of the photovoltaic module frame, and at least two layers of leak-proof water channels arranged in layers along the height direction below the top water channel. The first fixing edge 311 and the first buckle 35 are connected to the two sides of the opening of the top water channel. As shown in the figure, three layers of leak-proof water channels are provided, namely the upper leak-proof water channel 32, the middle leak-proof water channel 33, and the bottom leak-proof water channel 34. Normal rainwater is discharged through the top water channel 31. When the rainfall is heavy, some rainwater will leak into the lower three layers of leak-proof water channels to prevent rainwater from overflowing during heavy rainfall.

[0037] To accommodate the water channel, the width of the opening of the leak-proof water channel on both sides is greater than the gap between the frames of two adjacent photovoltaic modules. Grooves 12 are provided on the B-side of the two adjacent photovoltaic module frames. Therefore, the multi-layer leak-proof water channel elastically engages with the gap between the two adjacent photovoltaic module frames, and the two edges of the opening of the leak-proof water channel engage with the grooves on the B-side of the two photovoltaic module frames. The two side walls of the leak-proof water channel extend obliquely upwards. Therefore, the two side walls of the leak-proof water channel have considerable elasticity, facilitating the engagement of the two edges of the opening of the leak-proof water channel with the corresponding grooves on the B-side of the two photovoltaic module frames. However, it is not a complete seal; there is a certain leakage gap, further improving the installation reliability of the water channel. Moreover, this structure allows the upper water channel to leak into the lower leak-proof water channel when the water volume is large.

[0038] The first slot 11 protrudes from the upper part of the B side of the second photovoltaic module frame; an L-shaped bend 312 is provided between the first buckle 35 and the second side of the top water tank opening. Therefore, when the first buckle is installed, the first buckle is elastically engaged into the first slot by means of the L-shaped bend structure.

[0039] In some embodiments, the first fixing edge 311 is located above edge A of the first photovoltaic module frame, and a waterproof gasket 37 is provided between the first fixing edge 311 and edge A of the first photovoltaic module frame. The waterproof gasket 37 is made of rubber to prevent water leakage. The first fixing edge 311 is connected to edge A of the first photovoltaic module frame by screws 36. This facilitates the tightening of screws for fixation.

[0040] In the above technical solution, during the installation of the water channel, the top water channel 31 first engages with the first slot 11 on the first side photovoltaic module frame through the first buckle 35, the lower multi-layer anti-leakage water channel is squeezed into the groove 12 of the frame, and finally the first fixed edge 311 is connected to the first side photovoltaic module frame A by screws 36.

[0041] The photovoltaic modules are mounted on purlins 6. A pressure plate bolt assembly connects the frames of adjacent photovoltaic modules, and this assembly is fixed to the purlin, which can be a crossbeam mounted on a longitudinal beam. The pressure plate bolt assembly includes a pressure plate 4 and U-bolts 5. The U-bolts 5 connect the purlin 6 and the pressure plate 4, and the pressure plate 4 connects to the frames of the photovoltaic modules on both sides. The pressure plate bolt assembly secures the photovoltaic modules to the purlins. The U-bolts are nested on the outside of the purlins, with their two sides extending upwards through through holes in the pressure plate and connected to nuts. This facilitates the installation of the photovoltaic modules on the purlins.

[0042] In some embodiments, a second buckle 41 is provided at the bottom of side B of the first photovoltaic module frame, and a second slot 13 is provided on the first side of the pressure plate, with the second buckle 41 engaging with the second slot 13. Furthermore, a slot 14 is provided at the bottom of side B of the second photovoltaic module frame; a protruding edge 42 is provided on the second side of the pressure plate, which inserts into the slot 14. Thus, the pressure plate 4 is fixed to the crossbeam by U-bolts 5, with the protruding edge inserted into the slot, fixing the second photovoltaic module frame. Because the second buckle engages with the second slot, the first photovoltaic module frame can be installed after the pressure plate is fixed. This allows for the installation of the second photovoltaic module first, with the pressure plate bolt assembly fixing the pressure plate, pressing the protruding edge into the slot, and then installing the first photovoltaic module, engaging the second buckle with the second slot, facilitating the sequential installation of photovoltaic modules from the second direction to the first direction. Therefore, in this embodiment, the water guide channel effectively waterproofs the surface, is easy to install, and saves construction time.

[0043] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
