Description

Technical Field

[0001] This utility model relates to the field of solar energy technology, specifically a solar module frame locking structure. Background Technology

[0002] Solar modules are devices that convert sunlight into electricity. Currently, in solar energy applications, aluminum alloy frames enclose solar panels and a series of auxiliary materials to form a solar module. Solar panels are typically installed in a matrix configuration. Especially in large-scale photovoltaic (PV) installations, it's usually necessary to fix the frames of two solar modules together. This connection primarily utilizes external aluminum alloy lugs or frames, along with bolts, to secure the frames of the solar modules on both sides. However, a problem has been discovered during long-term use: on cloudy or rainy days, rainwater easily seeps down from the gaps between the two frames. While this may not cause immediate damage or structural destruction to the solar modules, long-term accumulation of acid corrosion and moisture intrusion can still cause erosion damage to the back of the solar modules, leading to inconvenience in the use and subsequent maintenance of the photovoltaic system.

[0004] Therefore, the purpose of this utility model is to provide a solar module frame locking structure to solve the problem mentioned in the background art that rainwater easily seeps down from the gap between the two side frames of the existing solar modules on cloudy or rainy days. Although it will not cause obvious damage or structural damage to the solar modules in a short period of time, long-term acid corrosion accumulation and moisture intrusion will still cause corrosion damage to the back of the solar modules, which will bring inconvenience to the use and later maintenance of photovoltaic equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solar module frame locking structure, comprising a solar module frame, a pressure plate, a U-shaped clip, and bolts, characterized in that: adjacent solar module frames are pressed together by the pressure plate and the U-shaped clip, and locked in place by bolts; The pressure plate includes an arched cover plate located directly above the junction line of the two solar panel frames. The two sides of the arched cover plate are fixed with pressing sections that abut against the upper part of the corresponding solar panel frames. The bottom of the pressing section has a sealing strip that abuts against the top of the solar panel frame along its length. A rib plate is vertically fixed in the middle of the arched cover plate and is located at the junction of the sides of the two solar panel frames.

[0011] As a preferred embodiment of the solar module frame locking structure described in this utility model, the top of the pressing section also has a guide groove along its length direction.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This solar module frame locking structure inserts the web rib of the pressure plate into the junction of the two solar modules, so that the pressing sections and sealing strips on both sides of the upper part are horizontally abutted against the top edge of the solar module. Then, the U-shaped clip is snapped into the bottom of the adjacent solar module, so that the two modules are firmly connected.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Figures 1-3The diagram shown is a complete structural schematic of a solar module frame locking structure according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of a solar module frame locking structure includes a solar module frame 100, a pressure plate 200, a U-shaped clip 300, and bolts 400. Its key feature is that the pressure plate 200 and the U-shaped clip 300 press adjacent solar module frames 100 together vertically, and the bolts 400 secure them in place. The pressure plate 200 includes an arched cover plate 210 located directly above the junction line of the two solar module frames 100. The arched cover plate 210 has fixed fasteners on both sides. A pressing section 220 abuts against the upper part of the corresponding solar frame 100. The bottom of the pressing section 220 has a sealing strip 250 that abuts against the top of the solar frame 100 along its length direction. An arched cover plate 210 is vertically fixed with a rib plate 230 at the center, and the rib plate 230 is located at the junction of the sides of the solar frames 100 on both sides. A U-shaped clip 300 is clipped at the bottom of the solar frames 100 on both sides. A bolt 400 passes through the U-shaped clip 300 from bottom to top and is threadedly connected to the rib plate 230.

[0019] Multiple threaded cylinders 240, matching the bolts 400, are fixed to the inner side of the rib plate 230 along its length. The bottom of the threaded cylinders 240 extends through the bottom of the rib plate 230. A through hole 3001 with a diameter larger than the inner diameter of the threaded cylinder 240 is provided in the center of the U-shaped clamp 300. In other embodiments, the through hole 3001 can also be a screw hole, which is not limited. After the bolts 400 are tightened onto the threaded cylinders 240, a gap is left between the top of the bolts 400 and the threaded cylinders 240. At the same time, a gap is left between the bottom of the rib plate 230 and the U-shaped clamp 300, so that the arched cover plate 210 has sufficient downward bending stroke. The bottom of the solar frame 100 has a stabilizing groove 1001 corresponding to the vertical section of the U-shaped clamp 300. The vertical section of the U-shaped clamp 300 also has a gasket 310 that abuts against the inner side of the stabilizing groove 1001. The bottom of the pressing section 220 has a mounting groove 2201 for engaging and positioning the sealing strip 250. The bottom of the sealing strip 250 has a plurality of waterproof ribs 2501 along its cross-sectional width direction, and the waterproof ribs 2501 are attached to the top surface of the solar frame 100. Specifically, by inserting the rib plate 230 of the pressure plate 200 into the junction of the two solar frame 100s, the pressing sections 220 and sealing strips 250 on both sides of the upper part are horizontally abutted against the top edge of the solar frame 100. Then, the U-shaped clip 300 is snapped into the bottom of the adjacent solar frame 100, so that the two frames are firmly connected. The bolt 400 is passed through the U-shaped clip 300 from bottom to top and screwed into the inside of the rib plate 230 and then gradually tightened, so that the arched cover plate 210 is pressed down and tightened, so that the pressing sections 220 and sealing strips 250 on both sides are tightly attached to the top surface of the solar frame 100, and with the cooperation of multiple waterproof ribs 2501, the top edge of the solar frame 100 is effectively sealed.

[0020] Furthermore, the top of the pressing section 220 also has a guide groove 2202 along its length. The guide groove 2202 can guide rainwater falling on the upper part of the pressing plate 200 downwards during rainy days, preventing excessive rainwater from falling at the junction of the sealing strip 250 and the solar frame 100.

[0021] In summary, the solar module frame locking structure of this embodiment, in use, involves inserting the web rib 230 of the pressure plate 200 into the junction of the two solar frame 100s, so that the pressing sections 220 and sealing strips 250 on both upper sides horizontally abut against the top edge of the solar frame 100. Then, the U-shaped clip 300 is inverted and inserted into the bottom of the adjacent solar frame 100, forming a secure connection between the two frames. Finally, the bolt 400 is passed through the U-shaped clip 300 from bottom to top and screwed into the web rib 230. The inner side is gradually tightened, so that the arched cover plate 210 is pressed down and tightened, so that the pressing sections 220 on both sides and the sealing strip 250 are tightly attached to the top surface of the solar frame 100. With the cooperation of multiple waterproof ribs 2501, an effective seal is formed on the top edge of the solar frame 100. This design not only ensures the connection between adjacent frames and the water-proof effect, but also prevents the seals from loosening and leaking due to displacement and vibration of adjacent frames, which brings convenience to the use and later maintenance of photovoltaic modules.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
