Description

Technical Field

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

[0002] A photovoltaic (PV) bracket is a fixed support for installing solar PV panels in well-lit locations such as rooftops. Currently, PV panels are typically installed by first drilling holes in the bracket and then securing the frame to the bracket with bolts.

[0003] However, in the actual installation process, the actual size of the photovoltaic panels needs to be adjusted according to the area of ​​the roof where they are installed. In other words, the size of the photovoltaic panels is not uniform and fixed. As a result, the brackets need to be measured and drilled on-site during installation, which makes the installation efficiency of the photovoltaic panels low and cannot meet the requirements of rapid on-site construction. Moreover, drilling holes in the brackets will reduce the overall structural strength of the brackets. Especially in the event of severe weather such as typhoons, drilling holes can easily cause the brackets to bend or even tear, which will affect the normal use of the photovoltaic panels. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a support connection structure for photovoltaic installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bracket connection structure for photovoltaic installation includes a slide, a connecting plate on the slide, the connecting plate abutting against the frame of the photovoltaic panel, an extension plate on the connecting plate, a limiting plate on the outer side of the extension plate, screws for abutting against the frame connected to the extension plate, and the bottom plate of the frame abutting against the limiting plate.

[0007] Preferably, the connecting plate is provided with a pressure plate, and the seat is equipped with a pressure block that abuts against the pressure plate.

[0008] Preferably, the pressure plate and the limiting plate are respectively disposed on the inner and outer sides of the extension plate, and the upper end of the extension plate is provided with an inwardly extending convex plate, which is disposed above the bottom plate.

[0009] Preferably, the extension plate has mounting holes for threaded connecting screws, and the screws pass through the mounting holes and abut against the frame.

[0010] Preferably, the slide has a support plate on both sides that abuts against the connecting plate, and the outer side of the support plate has a stop plate that abuts against the limiting frame.

[0011] Preferably, the lower part of the slide block is provided with a slide groove, the slide block is provided with a threaded hole that connects to the slide groove, and the pressure block is provided with a through hole corresponding to the position of the threaded hole.

[0012] Preferably, the pressure block is provided with a fixing member, a cover plate is snapped onto the fixing member, and a second through hole is opened on the fixing member corresponding to the position of the first through hole.

[0013] Preferably, the pressure block has an inwardly recessed groove, and the fixing member has a locking strip that engages with the groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. A connecting plate for abutting the frame of the photovoltaic panel is provided on the slide block. An extension plate and a limiting plate are provided on the connecting plate. The frame is pressed outward by screws on the extension plate so that the bottom plate of the frame abuts and is fixed to the limiting plate. The frame and the photovoltaic panel are then installed and fixed on the connecting plate. Compared with the existing drilling installation method, this utility model can fix the photovoltaic panel without drilling, making the installation of the photovoltaic panel more convenient and improving the installation efficiency of the photovoltaic panel. At the same time, it can also avoid the situation that the strength of the support structure is reduced due to drilling installation, thereby ensuring the reliability of the photovoltaic panel in subsequent use.

[0016] 2. The side of the frame is abutted by screws on the extension plate, and the bottom plate on the other side of the frame is abutted and fixed by the limiting plate.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1-6 As shown, a bracket connection structure for photovoltaic installation includes a slide block 1. The slide block 1 has a sliding groove 12 at its lower part. The sliding groove 12 facilitates the sliding adjustment of the slide block 1 so that the position of the slide block 1 can be adjusted according to the actual situation. The slide block 1 has a threaded hole 13 that communicates with the sliding groove 12. An external bolt can be threaded into the threaded hole 13 and pass through the threaded hole 13 downward to abut against and fix the slide block 1.

[0027] A connecting plate 3 is provided on the slide block 1, and the connecting plate 3 is used to abut against the frame 71 of the photovoltaic panel 7. (Refer to...) Figure 2 , Figure 3 As shown, the slide 1 has a support plate 11 on both sides that abuts against the connecting plate 3, that is, the connecting plate 3 is placed on the corresponding support plate 11, and the outer side of the support plate 11 is provided with a stop plate 14 that abuts against the limiting frame 71. The stop plate 14 restricts the connecting plate 3 from moving outward, so that the connecting plate 3 can be more stably set on the support plate 11.

[0028] The connecting plate 3 is provided with an extension plate 31, the side of the frame 71 is disposed close to the outer side of the extension plate 31, a limiting plate 33 is provided on the outer side of the extension plate 31, and the frame 71 is disposed between the extension plate 31 and the limiting plate 33.

[0029] The extension plate 31 is connected to a screw 6 that abuts against the frame 71. Specifically, the extension plate 31 has two mounting holes 311 for threaded connection of the screw 6, which are distributed vertically on the extension plate 31. The screw 6 is threaded into the mounting hole 311, and the screw 6 passes through the mounting hole 311 and abuts against the frame 71 outward. That is, one end of the screw 6 abuts against the side of the frame 71, and the frame 71 is squeezed by the screw 6, so that the bottom plate 72 of the frame 71 abuts against the limiting plate 33. In this way, the frame 71 is fixed at multiple points, which improves the strength of the frame 71 when it is connected and fixed, and ensures the stability and reliability of the photovoltaic panel 7 during installation and use.

[0030] Furthermore, the screws 6 on the extension plate 31 press the frame 71 outwards, so that the bottom plate 72 of the frame 71 abuts and is fixed to the limiting plate 33, thereby installing and fixing the frame 71 and the photovoltaic panel 7 on the connecting plate 3. Compared with the existing drilling installation method, this embodiment can fix the photovoltaic panel 7 without drilling, making the installation of the photovoltaic panel 7 more convenient and improving the installation efficiency of the photovoltaic panel 7.

[0031] To further improve the reliability of fixing the frame 71, the upper end of the extension plate 31 is provided with an inwardly extending convex plate 331. The convex plate 331 is located above the base plate 72. The convex plate 331 restricts the base plate 72 from coming off the connecting plate 3, so as to ensure that the frame 71 and the photovoltaic panel 7 can be better fixed on the connecting plate 3.

[0032] This embodiment avoids reducing the structural strength of the bracket due to drilling during installation, thus ensuring the reliability of the photovoltaic panel 7 in subsequent use. Further methods of fixing by drilling would require drilling holes in the frame 71 to secure it to the bracket with bolts. However, drilling holes in the frame 71 would inevitably reduce its structural strength. This embodiment, however, eliminates the need for drilling holes in the frame 71. Instead, the screw 6 acts as a retaining force, engaging with the limiting plate 33 and the protruding plate 331 to secure the frame 71 without damaging it. This ensures the frame 71 has good structural strength, making the photovoltaic panel 7 more reliable in use.

[0033] The connecting plate 3 is provided with a pressure plate 32, and the slide 1 is provided with a pressure block 2 that abuts against the pressure plate 32. The pressure plate 32 and the limiting plate 33 are respectively provided on the inner and outer sides of the extension plate 31. The pressure block 2 presses down to fix the pressure plate 32 so as to fix the connecting plate 3 on the slide 1 in a relatively stable manner.

[0034] Furthermore, the pressure block 2 is provided with a through hole 21 corresponding to the position of the threaded hole 13, and an external bolt passes through the through hole 21 to press and fix the pressure block 2 onto the slide block 1.

[0035] The pressure block 2 is provided with a fixing member 4, and a cover plate 5 is snapped onto the fixing member 4. The cover plate 5 extends to the photovoltaic panel 7 on both sides. The fixing member 4 is provided with a second through hole 41 corresponding to the position of the first through hole 21. That is, the external bolt passes through the first through hole 21 and the second through hole 41 and is threaded to the threaded hole 13 to press and fix the fixing member 4 and the pressure block 2 onto the slide 1.

[0036] The pressure block 2 has an inwardly recessed slot 22, and the fixing member 4 is provided with a locking strip 42 that engages with the slot 22. By engaging the locking strip 42 with the slot 22, the stability of the fixing member 4 when it is installed on the pressure block 2 is improved.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
