Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, and in particular to a photovoltaic panel connection structure. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that uses solar radiation to generate direct current (DC). PV panels are made almost entirely of semiconductor materials (such as silicon).

[0003] A photovoltaic panel connection structure is a device used to connect adjacent photovoltaic panels. It is usually made of materials such as aluminum alloy, steel, and stainless steel. The design of the photovoltaic panel connection structure needs to take into account a variety of factors, such as weight, wind resistance, corrosion resistance, and adaptability, to ensure that the photovoltaic panels can work safely, reliably, and efficiently.

[0004] Existing photovoltaic panel connection structures require controlling the distance between two photovoltaic panels during use, depending on the installation conditions. Most existing devices use the rotation of a control screw for adjustment. Since the photovoltaic panels are installed externally, the screw threads may loosen after a long period of installation, resulting in poor connection stability. Utility Model Content

[0008] The connecting mechanism includes a connecting part and an adjusting part;

[0009] The connecting part includes a fixed frame and two connecting rods, and the adjusting part includes a toothed plate and two inclined blocks;

[0010] The inner side of the first connecting frame is fixedly connected to two connecting rods. Two connecting sleeves are slidably sleeved on the surfaces of the two connecting rods. Two mounting plates are fixedly installed on the top surfaces of the two connecting sleeves. Two first springs are installed on the sides of the two mounting plates.

Two first connecting plates are slidably installed on the sides of the fixing frame. The outer sides of the two first connecting plates are fixedly connected to the sides of the first connecting frame and the second connecting frame, respectively.

[0011] Furthermore, the installation mechanism includes a pressure plate, which is slidably connected to the outer side of the first connecting frame. A fixing plate is fixedly installed on the outer side of the first connecting frame. A threaded rod is fixedly installed on the top surface of the pressure plate. The top surface of the threaded rod extends through the bottom surface of the fixing plate to the top of the fixing plate. An adjusting nut is rotatably installed on the top surface of the fixing plate through a bearing seat. The adjusting nut is threadedly connected to the threaded rod.

[0012] Furthermore, a sliding plate is slidably disposed on the top surface of the fixed frame, and an extrusion block is fixedly disposed on the back side of the sliding plate. Two connecting blocks are fixedly disposed on the side of the first connecting frame and the second connecting frame respectively. The inner sides of the two connecting blocks are fixedly connected to two inclined blocks respectively, and the inclined surfaces of the two inclined blocks are slidably connected to the inclined surfaces of the extrusion blocks respectively.

[0015] Furthermore, a wedge-shaped groove is provided on the top surface of the fixed frame, and a wedge-shaped block is slidably disposed in the wedge-shaped groove.

A slide rail is fixedly disposed on the top surface of the fixed frame, and two sliding frames are slidably sleeved on the surface of the slide rail.

During adjustment, the sliding plate moves backward, causing the extrusion block to move synchronously. As the extrusion block moves backward, the distance between the first and second connecting frames is adjusted by two inclined blocks. The sliding plate is then fixed by a fixed sleeve, a moving frame, a trapezoidal block, a toothed plate, and bolts, making it more stable after adjustment and preventing the distance between the first and second connecting frames from shifting. Two first springs bring the first and second connecting frames closer together after the extrusion block disengages from the two inclined blocks.

[0019] 2. The installation mechanism can fix two photovoltaic panels. The two sets of second springs and two sets of dampers can bring the two sets of positioning blocks closer to each other, thereby positioning the two photovoltaic panels. By controlling the two pressure plates to move downward, the two photovoltaic panels can be pressed together, thereby fixing them. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1-5 As shown, this embodiment proposes a photovoltaic panel connection structure, including a first connecting frame 1 and a second connecting frame 3. A connecting mechanism 2 is provided between the first connecting frame 1 and the second connecting frame 3, and an installation mechanism 4 is provided on the inner side of both the first connecting frame 1 and the second connecting frame 3.

[0029] The connecting mechanism 2 includes a connecting part and an adjusting part;

[0030] The connecting part includes two connecting rods 29 and a fixing frame 28, and the adjusting part includes two inclined blocks 24 and a toothed plate 217;

[0031] The inner side of the first connecting frame 1 is fixedly connected to two connecting rods 29. Two connecting sleeves 21 are slidably sleeved on the surfaces of the two connecting rods 29. Two mounting plates 22 are fixedly installed on the top surfaces of the two connecting sleeves 21. Two first springs 23 are installed on the sides of the two mounting plates 22. The two first springs 23 abut against the inner side of the first connecting frame 1. The fixing frame 28 is located between the first connecting frame 1 and the second connecting frame 3. Two first connecting plates 27 are slidably installed on the inner side of the fixing frame 28. The outer sides of the two first connecting plates 27 are fixedly connected to the sides of the first connecting frame 1 and the second connecting frame 3, respectively.

[0032] A sliding plate 219 is slidably mounted on the top surface of the fixed frame 28. An extrusion block 26 is fixedly mounted on the back of the sliding plate 219. Two connecting blocks 25 are fixedly mounted on the side adjacent to the first connecting frame 1 and the second connecting frame 3, respectively. The inner sides of the two connecting blocks 25 are fixedly connected to two inclined blocks 24, respectively. The inclined surfaces of the two inclined blocks 24 are slidably connected to the inclined surfaces of the extrusion block 26, respectively. The top surface of the fixed frame 28 is fixedly connected to the bottom surface of the toothed plate 217. A fixing sleeve 212 is fixedly mounted on the top surface of the sliding plate 219. A movable frame 215 is slidably disposed within the 212. A trapezoidal block 216 is fixedly disposed at the end of the movable frame 215. An extrusion groove is formed on the top surface of the movable frame 215. The surface of the trapezoidal block 216 is connected to the tooth surface of the toothed plate 217. A bolt 214 extending into the extrusion groove is disposed through the top surface of the fixed sleeve 212. A fixing nut 213 is fixedly disposed on the top surface of the fixed sleeve 212, and the fixing nut 213 is threadedly connected to the bolt 214. A second connecting plate 220 is fixedly disposed on one side of the fixed sleeve 212. Figure 5As shown, an elastic element 221 is fixedly installed on the left side of the second connecting plate 220, and the left side of the elastic element 221 is fixedly connected to the inner left end face of the movable frame 215; a wedge-shaped groove is opened on the top surface of the fixed frame 28, and a wedge block 218 is slidably installed in the wedge groove. The top surface of the wedge block 218 is fixedly connected to the bottom surface of the sliding plate 219. A slide rail 210 is fixedly installed on the top surface of the fixed frame 28, and two sliding frames 211 are slidably sleeved on the surface of the slide rail 210. One side of each of the two sliding frames 211 is fixedly connected to two inclined blocks 24.

[0033] In this embodiment, the distance between the first connecting frame 1 and the second connecting frame 3 can be adjusted by the connecting mechanism 2. During adjustment, the sliding plate 219 moves backward, which drives the pressing block 26 to move synchronously. When the pressing block 26 moves backward, the distance between the first connecting frame 1 and the second connecting frame 3 can be adjusted by the two inclined blocks 24. The sliding plate 219 can be fixed by the fixed sleeve 212, the moving frame 215, the trapezoidal block 216, the toothed plate 217, and the bolt 214, making it more stable after the adjustment is completed, so that the distance between the first connecting frame 1 and the second connecting frame 3 will not move. By setting two first springs 23, the first connecting frame 1 and the second connecting frame 3 can move closer to each other after the pressing block 26 is separated from the two inclined blocks 24. By setting this connecting mechanism 2, the position between the first connecting frame 1 and the second connecting frame 3 can be more stable after the adjustment is completed.

[0034] Example 2

[0035] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the installation mechanism 4 includes a pressure plate 41, which is slidably connected to the outer side of the first connecting frame 1. A fixing plate 47 is fixedly installed on the outer side of the first connecting frame 1. A threaded rod 44 is fixedly installed on the top surface of the pressure plate 41. The top surface of the threaded rod 44 extends through the bottom surface of the fixing plate 47 and above the fixing plate 47. An adjusting nut 46 is rotatably installed on the top surface of the fixing plate 47 through a bearing seat. The adjusting nut 46 is threadedly connected to the threaded rod 44. Two sets of second springs 43 and two sets of dampers 49 are fixedly installed on the inner side of the bottom of the first connecting frame 1. Two positioning blocks 42 are fixedly installed between the two sets of second springs 43 and the two sets of dampers 49. A dovetail groove is opened on the first connecting frame 1. A dovetail block 45 is provided on the inner wall of the dovetail groove. The dovetail block 45 is fixedly connected to the pressure plate 41.

[0036] In this embodiment, the two photovoltaic panels can be fixed by the installation mechanism 4, and the two sets of positioning blocks 42 can be brought closer to each other by the two sets of second springs 43 and two sets of dampers 49, thereby positioning the two photovoltaic panels. By controlling the two pressure plates 41 to move downward, the two photovoltaic panels can be pressed together, thereby fixing them.

[0037] In use, two photovoltaic panels are placed inside the first connecting frame 1 and the second connecting frame 3. Two sets of second springs 43 and two sets of dampers 49 bring the two positioning blocks 42 closer together, thus positioning the two photovoltaic panels. Rotating the two adjusting nuts 46 causes the two pressure plates 41 to move downwards via two threaded rods 44 and two dovetail blocks 45, fixing the photovoltaic panels in place. When the distance between the first connecting frame 1 and the second connecting frame 3 needs adjustment, the sliding plate 219 is manually moved backwards. This movement of the sliding plate 219 causes the pressing block 26 to move synchronously. As the pressing block 26 moves backwards, the distance between the first connecting frame 1 and the second connecting frame 3 can be adjusted via two inclined blocks 24. When the moving plate 219 moves, it can drive the moving frame 215 to move synchronously. After the moving frame 215 stops moving, the trapezoidal block 216 moves to the right through the elastic element 221. When the trapezoidal block 216 moves to the right, it can engage with the tooth surface of the toothed plate 217. Then, by rotating the bolt 24, the bottom surface of the bolt 24 can contact the inner wall of the extrusion groove. After the bottom surface of the bolt 24 contacts the inner wall of the extrusion groove, the moving frame 215 moves. After the moving frame 215 is fixed, the trapezoidal block 216 can be fixed. After the trapezoidal block 216 is fixed, the sliding plate 219 is fixed through the toothed plate 217, thereby fixing the distance between the first connecting frame 1 and the second connecting frame 3. By setting two first springs 23, the first connecting frame 1 and the second connecting frame 3 can be brought closer to each other after the extrusion block 26 is separated from the two inclined blocks 24.

[0038] The above are merely preferred embodiments of this utility model, and the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve the same technical problem and achieve the same technical effect are all covered within the protection scope of this utility model.
