Description

Technical Field

[0001] This application relates to the field of photovoltaic mounting accessories, and in particular to side-mounted module components. Background Technology

[0002] Currently, single-sided pressure block modules are a crucial component in solar photovoltaic (PV) panel installation. A solar panel consists of laminates, aluminum alloy components, and junction boxes. The laminate comprises tempered glass, the main solar cells, and a backsheet. The aluminum alloy frame surrounds the laminate, protecting it and providing sealing and support. Pressure block modules are essential for connecting solar panels and are categorized into center pressure blocks and side pressure blocks (also known as edge pressure blocks).

[0003] The pressure block is usually connected to the guide rail first, and the bottom of the pressure block is fixed on the guide rail. The existing pressure block and guide rail connection usually rely on friction to limit the position, which is prone to lateral movement, causing the top position of the pressure block to deviate. At the same time, the position adjustment of the top of the existing pressure block is also relatively inconvenient. The position of the top pressure block is adjusted by changing the connection length with the guide rail by rotating the bolt. Utility Model Content

[0004] To address the issues of relying on friction for positioning, which can easily lead to lateral movement and inconvenient adjustment of the top position of the pressure block, this application provides a side pressure block assembly.

[0005] The side pressure block assembly provided in this application adopts the following technical solution: it includes a telescopic sleeve rod, a telescopic rod is movably sleeved inside the telescopic sleeve rod, both the telescopic sleeve rod and the telescopic rod are L-shaped, a first threaded rod is rotatably connected through one side of the telescopic sleeve rod, a threaded sleeve rod is movably installed in the middle of the top of the telescopic sleeve rod, a nut is threadedly connected to the outer wall of the threaded sleeve rod, a pressure plate is fixed at the bottom of the nut, a second threaded rod is threadedly connected inside the threaded sleeve rod, a connecting block is rotatably connected to the outer wall of the second threaded rod, and a pressure block body is fixed at one end of the connecting block.

[0006] By adopting the above technical solution, the horizontal height of the pressure block is changed by rotating the second threaded rod on the threaded sleeve rod. The connecting block is rotatably connected to the second threaded rod, which can keep the pressure block in contact with the photovoltaic panel.

[0007] Preferably, a pad is fixed to the end of the telescopic rod away from the telescopic sleeve rod, and the top of the pad and the top of the telescopic sleeve rod are on the same horizontal plane.

[0008] By adopting the above technical solution, the top of the telescopic rod and the telescopic sleeve rod fits into each other with the bottom of the guide rail, and a groove is opened in the middle of the top of the guide rail and bent downward.

[0009] Preferably, the telescopic rod has a threaded hole through the middle of one end near the telescopic sleeve rod, and the first threaded rod is threadedly connected to the inside of the telescopic sleeve rod.

[0010] By adopting the above technical solution, the first threaded rod is rotated to drive the telescopic sleeve rod to slide inside the telescopic rod, so that the top protrusion of the telescopic rod and the telescopic sleeve rod can be pressed against the bottom of the guide rail.

[0011] Preferably, a connecting sleeve block is fixed at the bottom of the threaded sleeve rod, and a connecting disc is fixed at the middle of the top of the telescopic sleeve rod, with the connecting sleeve block and the connecting disc being rotatably connected.

[0012] By adopting the above technical solution, the threaded sleeve rod can rotate at the top of the telescopic sleeve rod through the cooperation of the connecting sleeve block and the connecting plate.

[0013] Preferably, the vertical cross-section of the connecting plate is T-shaped, and the vertical cross-section of the connecting sleeve is inverted U-shape.

[0014] By adopting the above technical solution, the contact area between the connecting sleeve and the connecting plate is increased, thereby increasing the connection stability between the connecting plate and the connecting sleeve and preventing the threaded sleeve rod from separating from the telescopic sleeve rod.

[0015] Preferably, the inner wall of the threaded sleeve is provided with an internal thread, which is used in conjunction with the second threaded rod, and the outer wall of the threaded sleeve is provided with an external thread, which is used in conjunction with the nut.

[0016] By adopting the above technical solution, the horizontal height of the pressure block is changed by rotating the second threaded rod on the threaded sleeve rod. The connecting block is rotatably connected to the second threaded rod, which can keep the pressure block in contact with the photovoltaic panel.

[0017] Preferably, the pressure plate is circular, and the diameter of the pressure plate is greater than the maximum distance between the two ends of the telescopic sleeve rod and the telescopic rod.

[0018] By adopting the above technical solution, the pressure plate can be moved up and down on the threaded sleeve by rotating the threaded cap, thereby changing the distance between the telescopic sleeve and the pressure plate, and can be tightly connected with the guide rail.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. This application uses the first threaded rod to drive the telescopic sleeve rod to slide inside the telescopic rod, so that the top protrusion of the telescopic rod and the telescopic sleeve rod can be pressed against the bottom of the guide rail. By rotating the threaded cap, the pressure plate is driven to move up and down on the threaded sleeve rod, thereby changing the distance between the telescopic sleeve rod and the pressure plate, which can be tightly connected to the guide rail. At the same time, the top of the pad block and the top of the telescopic sleeve rod are on the same horizontal plane, so that the top of the telescopic rod and the telescopic sleeve rod fits against the bottom of the guide rail, thereby achieving quick engagement with the guide rail. At the same time, the spacing of the bottom connecting blocks can be quickly adjusted according to the size of the guide rail.

[0021] 2. This application achieves a change in the horizontal height of the pressure block by rotating the second threaded rod on the threaded sleeve rod. The connecting block is rotatably connected to the second threaded rod, which keeps the pressure block in contact with the photovoltaic panel. The threaded sleeve rod will not rotate when adjusting the pressure block, thereby achieving the effect of individual adjustment of the top pressure block, making the adjustment more convenient.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a side pressure block assembly, including a telescopic sleeve rod 2, with a telescopic rod 3 movably sleeved inside the telescopic sleeve rod 2. Both the telescopic sleeve rod 2 and the telescopic rod 3 are L-shaped. A first threaded rod 6 is rotatably connected through one side of the telescopic sleeve rod 2. A threaded sleeve rod 9 is movably installed in the middle of the top of the telescopic sleeve rod 2. A nut 93 is threadedly connected to the outer wall of the threaded sleeve rod 9. A pressure plate 11 is fixed at the bottom of the nut 93. By rotating the threaded nut 93, the pressure plate 11 is moved up and down on the threaded sleeve rod 9, thereby changing the distance between the telescopic sleeve rod 2 and the pressure plate 11, which can be tightly connected to the guide rail 1. A second threaded rod 10 is threadedly connected inside the threaded sleeve rod 9. A connecting block 12 is rotatably connected to the outer wall of the second threaded rod 10. A pressure block body 13 is fixed at one end of the connecting block 12. The pressure block body 13 is L-shaped. By rotating the second threaded rod 10 on the threaded sleeve rod 9, the horizontal height of the pressure block body 13 is changed. The connecting block and the second threaded rod 10 are rotatably connected, which can keep the pressure block body 13 in contact with the photovoltaic panel.

[0029] Reference Appendix Figure 4 The telescopic rod 3 has a pad 5 fixed at the end away from the telescopic sleeve rod 2. The top of the pad 5 and the top of the telescopic sleeve rod 2 are on the same horizontal plane, so that the top of the telescopic rod 3 and the top of the telescopic sleeve rod 2 fit together with the bottom of the guide rail 1. A groove is opened in the middle of the top of the guide rail 1 and it is bent downward.

[0030] Reference Appendix Figure 3 The telescopic rod 3 has a threaded hole through the middle of one end near the telescopic sleeve rod 2. The first threaded rod 6 is threadedly connected to the inside of the telescopic sleeve rod 2. By rotating the first threaded rod 6, the telescopic sleeve rod 2 is driven to slide inside the telescopic rod 3, so that the top protrusion of the telescopic rod 3 and the telescopic sleeve rod 2 can be pressed against the bottom of the guide rail 1.

[0031] Reference Appendix Figure 3 The threaded sleeve 9 has a connecting sleeve block 8 fixed at its bottom, and a connecting plate 7 fixed at the middle of the top of the telescopic sleeve 2. The connecting sleeve block 8 and the connecting plate 7 are rotatably connected. Through the cooperation of the connecting sleeve block 8 and the connecting plate 7, the threaded sleeve 9 can rotate at the top of the telescopic sleeve 2.

[0032] Reference Appendix Figure 3 The vertical cross-section of the connecting plate 7 is T-shaped, and the vertical cross-section of the connecting sleeve block 8 is inverted U-shaped. The contact area between the connecting sleeve block 8 and the connecting plate 7 is increased, which increases the connection stability between the connecting plate 7 and the connecting sleeve block 8 and prevents the threaded sleeve rod 9 from separating from the telescopic sleeve rod 2.

[0033] Reference Appendix Figure 2 and 3The inner wall of the threaded sleeve rod 9 is provided with an internal thread 91, which is used in conjunction with the second threaded rod 10. The outer wall of the threaded sleeve rod 9 is provided with an external thread 92, which is used in conjunction with the nut 93. By rotating the second threaded rod 10 on the threaded sleeve rod 9, the horizontal height of the pressure block 13 is changed. The connecting block is rotatably connected to the second threaded rod 10, which can keep the pressure block 13 in contact with the photovoltaic panel.

[0034] Reference Appendix Figure 2 The pressure plate 11 is circular and its diameter is greater than the maximum distance between the ends of the telescopic sleeve 2 and the telescopic rod 3. By rotating the threaded cap 93, the pressure plate 11 is driven to move up and down on the threaded sleeve 9, thereby changing the distance between the telescopic sleeve 2 and the pressure plate 11, so that it can be tightly connected with the guide rail 1.

[0035] The implementation principle of the side pressure block assembly in this application embodiment is as follows: First, adjust the telescopic rod 3 and telescopic sleeve rod 2 according to the distance between the two internal protruding ends at the top of the guide rail 1. By rotating the first threaded rod 6, the telescopic sleeve rod 2 is driven to slide inside the telescopic rod 3, so that the top protruding ends of the telescopic rod 3 and the telescopic sleeve rod 2 can be pressed against the bottom of the guide rail 1. By rotating the threaded cap 93, the pressure plate 11 is driven to move up and down on the threaded sleeve rod 9, thereby changing the distance between the telescopic sleeve rod 2 and the pressure plate 11, so that it can be tightly connected with the guide rail 1. At the same time, the top of the pad 5 and the top of the telescopic sleeve rod 2 are located on the same horizontal plane, so that the top of the telescopic rod 3 and the telescopic sleeve rod 2 are in contact with the bottom of the guide rail 1. Finally, rotate the second threaded rod 10 on the threaded sleeve rod 9, thereby changing the horizontal height of the pressure block body 13. The connecting block is rotatably connected to the second threaded rod 10, which can keep the pressure block body 13 in contact with the photovoltaic panel, thereby quickly connecting the assembly to the guide rail 1. After connection, the pressure block body 13 can also be quickly used to limit the photovoltaic panel.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
