Technical Field
[0001] This utility model relates to the field of photovoltaic module connection technology, specifically a waterproof photovoltaic module connection structure. Background Technology
[0002] Solar photovoltaic (PV) systems, also known as photovoltaics, are facilities that convert solar energy into direct current (DC) electricity using the photovoltaic effect of photovoltaic semiconductor materials. Building-integrated photovoltaics (BIPV) is a type of distributed photovoltaic power generation system that integrates photovoltaic modules into buildings. Currently, the global building and infrastructure industries account for 50% of total energy consumption. Given the excessive energy consumption of buildings and the backdrop of zero-energy building policies, zero-energy buildings have become an inevitable trend. BIPV, with its advantages of saving building materials, reliable and flexible power supply, and energy conservation, will become the mainstream form of zero-energy buildings.
[0003] However, existing photovoltaic (PV) panels have significant technical flaws in their installation process: currently, the connection between PV panels mainly relies on connecting frames and bolts for fixing. However, before bolt installation, continuous manual support is required to maintain the alignment of the mounting holes. This process is not only inefficient but also prone to misalignment due to personnel dropping their hands or accidental contact, requiring repeated adjustments to realign them, severely impacting construction progress. Furthermore, the stability of manual support is even more difficult to guarantee when working at heights or over large spans, further increasing installation difficulty and safety risks. Summary of the Invention
[0004] The purpose of this invention is to provide a waterproof photovoltaic module connection structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof photovoltaic module connection structure, including a photovoltaic panel body, a connecting frame installed on the top of the photovoltaic panel body, and an installation base plate installed on the bottom of the photovoltaic panel body. The connecting frame and the installation base plate are fixed by bolts, the bolts penetrating the photovoltaic panel body. The outer surfaces of both the photovoltaic panel body and the installation base plate are provided with mating holes, and the outer surface of the connecting frame is provided with connecting components and protective components. The connection component includes: Fixed posts are used for positioning and docking. A cavity is used to stabilize its internal structure. Release element, used to release the limit for easy separation.
[0006] Preferably, the fixing post is fixed to the bottom of the connecting frame. The fixing post has a cavity inside, and a locking block is provided inside the cavity. The locking block passes through the fixing post and is slidably connected to the fixing post. The connecting post is fixed to the bottom of the inner wall of the cavity. A spring is fixed to the outer surface of the connecting post. The end of the spring away from the connecting post is fixed to the outer surface of the locking block. When the fixing post is inserted into the hole in the base plate, the inclined surface of the locking block contacts the hole wall and retracts to compress the spring. After passing through the base plate, the spring returns to its original position, causing the flat side of the locking block to abut against the bottom of the base plate, thereby achieving a stable locking of the photovoltaic panel, the connecting frame, and the base plate.
[0007] Preferably, the release mechanism includes a circular plate rotatably connected to the top of the inner wall of the cavity. A movable groove is formed at the bottom of the circular plate. A circular rod is fixed to the top of the locking block, with its outer surface abutting against the inner wall of the movable groove. A rotating rod is fixed to the top of the circular plate, its top passing through a fixed column and a connecting frame, and is rotatably connected to both. A groove is formed at the top of the rotating rod, with an arc-shaped groove forming its inner wall. A short rod is installed inside the groove, and an abutting rod is fixed to its outer surface, abutting against the inner wall of the arc-shaped groove. A pull plate is fixed to the top of the short rod. Pulling the pull plate disengages the short rod from the rotating rod, and the abutting rod pushes the rotating rod to rotate 90° along the arc-shaped groove. The movable groove pushes the circular rod from the concave area to the convex area, pulling the locking block back into the cavity, thus releasing the locking mechanism and facilitating disassembly.
[0008] Preferably, the protective component includes a through hole on the outer surface of the pull plate. A movable rod is rotatably connected to the outer surface of the connecting frame. A sliding groove is formed at the bottom of the movable rod, and a sliding column is slidably connected to the inner wall of the sliding groove. A second spring is fixed to the top of the sliding column, and the top of the second spring is fixed to the top of the inner wall of the sliding groove. A baffle is fixed to the outer surface of the movable rod, and a stabilizing groove is formed on the outer surface of the connecting frame. The baffle is misaligned with the through hole to prevent accidental contact with the pull plate and thus affecting the locking of the locking block. The movable rod is moved to align the baffle with the through hole. The sliding column is engaged in the stabilizing groove, fixing the movable rod. At this point, the pull plate can be safely pulled for operation.
[0009] Preferably, the movable groove is wavy, so that when it rotates, it can contact the outer surface of the round rod, thereby driving the round rod and the locking block to move synchronously.
[0010] Preferably, the end of the locking block away from the spring is set as an inclined surface. When the inclined surface is abutted, the locking block can move into the cavity without affecting the docking.
[0011] Preferably, the angle between the starting end and the ending end of the arc-shaped groove is 90°, and when the contact rod moves with the short rod, it can drive the rotating rod to rotate synchronously by 90°.
[0012] Preferably, the bottom of the sliding column is designed to be arc-shaped. When the movable rod rotates, the inner wall of the arc-shaped stabilizing groove of the sliding column abuts against it, which allows the sliding column to move into the sliding groove without affecting the normal rotation of the movable rod.
[0013] Compared with the prior art, this utility model provides a waterproof photovoltaic module connection structure, which has the following advantages: 1. This waterproof photovoltaic module connection structure, through its designed connecting components, allows for easy installation by aligning the fixing post with the mating hole. Upon insertion, the hole wall compresses the locking block, retracting it and compressing spring one. After passing through the base plate, spring one pushes the locking block back to its original position, causing its flat side to abut against the bottom of the base plate, forming a stable lock. Bolt fixing can then be performed without manual support, significantly improving installation efficiency. For disassembly, pulling the pull plate disengages the short rod from the rotating rod. The contact rod pushes the rotating rod 90° along the arc-shaped groove, causing the circular plate to push the circular rod in the movable groove from the concave side to the convex side, thereby retracting the locking block and completing quick disassembly.
[0014] This waterproof photovoltaic module connection structure, through its protective components, prevents accidental unlocking of the locking block by accidentally touching the pull plate when the baffle and through-hole are misaligned. For disassembly, rotate the movable rod to align the baffle with the through-hole. At this point, the sliding column slides along the stabilizing groove and compresses the second spring. Once the sliding column is fully aligned with the stabilizing groove, the second spring releases, pushing the sliding column into the groove to lock the movable rod and prevent it from springing back. After locking, the pull plate can be safely pulled for disassembly. This design ensures both installation stability and controllability during disassembly. Attached Figure Description

Detailed Implementation
[0017] like Figures 1-10 As shown, this utility model provides a technical solution: a waterproof photovoltaic module connection structure, including a photovoltaic panel body 1, a connecting frame 2 installed on the top of the photovoltaic panel body 1, and a mounting base plate 3 installed on the bottom of the photovoltaic panel body 1. The connecting frame 2 and the mounting base plate 3 are fixed by bolts, which penetrate the photovoltaic panel body 1. The outer surfaces of both the photovoltaic panel body 1 and the mounting base plate 3 are provided with mating holes 4. The outer surface of the connecting frame 2 is provided with a connecting component 5 and a protective component 6. The connecting component 5 includes: a fixing post 50, a cavity 51, a locking block 52, a spring 53, a connecting post 54, a release component 55, a round plate 550, a rotating rod 551, a movable groove 552, a pull plate 553, a groove 554, a short rod 555, a contact rod 556, an arc groove 557, and a round rod 558.
[0018] A fixed post 50 is fixed to the bottom of the connecting frame 2. A cavity 51 is formed inside the fixed post 50, and a locking block 52 is disposed inside the cavity 51. The locking block 52 passes through the fixed post 50 and is slidably connected to the fixed post 50. A connecting post 54 is fixed to the bottom of the inner wall of the cavity 51. A spring 53 is fixed to the outer surface of the connecting post 54. The end of the spring 53 away from the connecting post 54 is fixed to the outer surface of the locking block 52. The releasing component 55 includes a circular plate 550, which is rotatably connected to the top of the inner wall of the cavity 51. A movable groove 552 is formed at the bottom of the circular plate 550. A circular rod 558 is fixed to the top of the locking block 52, and the outer surface of the circular rod 558 abuts against the inner wall of the movable groove 552. A rotating rod 551 is fixed to the top of the circular plate 550. The top of the rotating rod 551 passes through the fixed post 50 and the connecting frame 2, and the rotating rod 551 is rotatably connected to the fixed post 50 and the connecting frame 2. The top of 551 has a groove 554, and the inner wall of the groove 554 has an arc-shaped groove 557. A short rod 555 is installed inside the groove 554, and an abutment rod 556 is fixed on the outer surface of the short rod 555. The outer surface of the abutment rod 556 abuts against the inner wall of the arc-shaped groove 557. A pull plate 553 is fixed on the top of the short rod 555. The movable groove 552 is wavy. The end of the locking block 52 away from the spring 53 is set as an inclined surface. The angle between the starting end and the end of the arc-shaped groove 557 is 90°. When the fixing post 50 is inserted into the docking hole 4 of the mounting base plate 3, the inclined surface of the locking block 52 will contact the hole wall, forcing the locking block 52 to retract into the cavity 51 and compress the spring 53. When the locking block 52 completely passes through the mounting base plate 3, the spring 53 is released to reset the locking block 52, and its flat side abuts against the bottom of the base plate, thereby realizing the stable locking of the photovoltaic panel body 1, the connecting frame 2 and the mounting base plate 3. At this point, the baffle 65 is misaligned with the through hole 60, preventing accidental contact with the pull plate 553 and loosening of the locking block 52. This design allows for direct bolt fixing without manual support, improving installation efficiency. During disassembly, pulling the pull plate 553 disengages the short rod 555 from the rotating rod 551. The contact rod 556 pushes the rotating rod 551 to rotate 90° along the arc-shaped groove 557, causing the circular plate 550 to rotate. At this time, the movable groove 552 pushes the circular rod 558 from the concave area to the convex area, pulling the locking block 52 back into the cavity 51, thus completing the disassembly.
[0019] The protective component 6 includes a through hole 60 on the outer surface of the pull plate 553. A movable rod 61 is rotatably connected to the outer surface of the connecting frame 2. A groove 62 is provided at the bottom of the movable rod 61. A sliding column 63 is slidably connected to the inner wall of the groove 62. A second spring 64 is fixed to the top of the sliding column 63, and the top of the second spring 64 is fixed to the top of the inner wall of the groove 62. A baffle 65 is fixed to the outer surface of the movable rod 61. A stabilizing groove 66 is provided on the outer surface of the connecting frame 2. The bottom of the sliding column 63 is arc-shaped. When the baffle 65 is misaligned with the through hole 60, it can prevent accidental contact with the pull plate 553 and affect the locking of the locking block 52. To pull the pull plate 553, the movable rod 61 needs to be rotated to align the baffle 65 with the through hole 60. At this point, the sliding column 63 slides along the stabilizing groove 66 and compresses the second spring 64 until the sliding column 63 is aligned with the stabilizing groove 66. The second spring 64 is then released, pushing the sliding column 63 into the stabilizing groove 66, thereby fixing the movable rod 61 and preventing it from rotating. At this point, the pull plate 553 can be safely pulled to operate.
[0020] When bolt installation is required, the connecting bracket 2 and the mounting base plate 3 are respectively attached to the top and bottom of the photovoltaic panel body 1. At the same time, the fixing post 50 is installed into the mating hole 4 of the mounting base plate 3. At this time, the inclined surface of the locking block 52 abuts against the inner wall of the mating hole 4, and the locking block 52 moves into the cavity 51. At this time, the spring 53 is compressed. When the locking block 52 has completely passed through the mounting base plate 3, the spring 53 is released, and the locking block 52 returns to its original position. At this time, the side of the locking block 52 away from the inclined surface is aligned with the bottom of the mounting base plate 3. The mutual contact ensures the photovoltaic panel body 1, connecting frame 2, and mounting base plate 3 are mutually restrained and stable. Simultaneously, the staggered position of the baffle 65 and the through hole 60 restrains the pull plate 553, preventing accidental external contact with the pull plate 553 and affecting the restraint of the locking block 52 on the mounting base plate 3. This allows for normal bolt fixing without manual support, improving bolt installation efficiency. The concave design of the connecting frame 2 guides rainwater out, and all components are coated with a waterproof coating to prevent rainwater from entering. Soaking affects usability. When disassembly is required, when removing the bolts, rotate the movable rod 61 so that the baffle 65 is parallel to the through hole 60. Simultaneously, as the movable rod 61 rotates, the outer surface of the sliding column 63 abuts against the inner surface of the stabilizing groove 66. At this point, the sliding column 63 moves into the sliding groove 62, compressing the second spring 64. When the sliding column 63 is parallel to the stabilizing groove 66, the second spring 64 releases, thus driving the sliding column 63 into the stabilizing groove 66. This stabilizes the movable rod 61, preventing it from rotating and affecting stability. Qualitatively, at this point, the pull plate 553 can be pulled normally. At this point, the short rod 555 moves away from the rotating rod 551. At this point, the outer surface of the contact rod 556 contacts the inner wall of the arc groove 557, which can drive the rotating rod 551 to rotate 90°, so that the circular plate 550 rotates synchronously. At this point, the inner wall of the movable groove 552 contacts the outer surface of the circular rod 558. At this point, the circular rod 558 gradually moves from the recess of the movable groove 552 to the protrusion of the movable groove 552, which can drive the locking block 52 into the cavity 51. At this point, it can be dismantled normally.
[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
