Description

Technical Field

[0001] The utility model relates to the field of photovoltaic frames, in particular to a photovoltaic frame with a lightning protection function. Background Art

[0002] The solar module frame refers to the aluminum alloy profile fixed frame and bracket that constitutes the photovoltaic solar panel assembly. The photovoltaic frame plays the role of fixing and sealing the solar cell assembly, enhancing the strength of the assembly and extending the service life. Lightning protection components will be installed on some photovoltaic frames to play a lightning protection role and prevent lightning from causing serious damage to the photovoltaic frame.

[0003] According to a Chinese patent with publication number CN219287443U, a photovoltaic frame with lightning protection function is disclosed. The upper L-shaped clip and the lower L-shaped clip of the utility model are tightly connected between the photovoltaic frame, and the conductive strip guides lightning to the ground, ensuring that the frame has an efficient lightning protection effect. The lightning protection guide is stuck on the outside of the photovoltaic frame, and the fastening bolts passing through the upper L-shaped clip and the lower L-shaped clip make the lightning protection guide easy to install, maintain and replace.

[0004] The L-shaped clip and the lower L-shaped clip are fixed to the photovoltaic frame by screwing the fastening bolts into the L-shaped clip and the lower L-shaped clip, thereby preventing the L-shaped clip and the lower L-shaped clip from falling off the photovoltaic frame. However, before screwing the fastening bolts into the L-shaped clip and the lower L-shaped clip, the bolt holes on the L-shaped clip and the lower L-shaped clip need to be aligned before the fastening bolts can be screwed into the L-shaped clip and the lower L-shaped clip. During the installation process, the L-shaped clip and the lower L-shaped clip may move, and the position of the L-shaped clip or the lower L-shaped clip needs to be adjusted frequently to align the bolt holes, which makes it inconvenient to quickly fix the L-shaped clip and the lower L-shaped clip, thereby reducing the installation efficiency of the lightning protection structure. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a photovoltaic frame with lightning protection function to solve the technical problem that it is inconvenient to quickly screw the fastening bolts into the L-shaped clip and the lower L-shaped clip for fixing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photovoltaic frame with lightning protection function, comprising a frame body, an upper splint and a lower splint, a first through hole being provided on the upper splint, an adjustment assembly being provided on the top of the lower splint, and the adjustment assembly comprising a guide column installed on the top of the lower splint and clamping holes on both sides of the first through hole, a cavity being provided inside the guide column, and a fixed plate being provided inside the cavity, a plurality of springs being installed on both sides of the fixed plate, one end of the spring being connected to a movable plate, and one side of the movable plate being connected to a plurality of clamping columns extending through the outside of the guide column, and a push rod extending through the outside of the guide column being installed above one side of the movable plate.

[0007] By adopting the above technical solution, when the upper clamping plate needs to be clamped on the frame body, the user can press the push rod to move the push rod into the cavity and drive the movable plate to move, so that the movable plate compresses the spring.

[0008] Furthermore, two slide grooves are provided on the lower splint, and slide bars are installed on the outer surface and back of the upper splint, and the slide bars are located inside the slide grooves.

[0009] By adopting the above technical solution, when the upper clamping plate moves, it will drive the slide bar to slide inside the slide groove, thereby improving the stability of the upper clamping plate when moving.

[0010] Furthermore, a mounting groove is provided on one side of the top of the upper splint, and a connecting seat is provided in the mounting groove. A lightning ring is installed at the bottom of the connecting seat, and a lightning rod is installed inside the lightning ring.

[0011] By adopting the above technical solution, when a lightning strike occurs, the lightning can be guided by the lightning induction needle to prevent the lightning from directly acting on the solar cell panels, thereby improving the protection effect of the solar cell panels.

[0012] Furthermore, the upper clamping plate and the lower clamping plate are both provided with second through holes, and conductive strips are inserted into the second through holes.

[0013] By adopting the above technical solution, the second through hole is provided to facilitate the insertion of the conductive strip, and the conductive strip is provided to facilitate electrical conduction.

[0014] Furthermore, a solar cell panel is installed inside the frame body, a lower clamping plate is clamped on the bottom of the frame body, and an upper clamping plate is clamped on the top of the frame body.

[0015] By adopting the above technical solution, the upper and lower clamping plates are arranged so that the lightning protection structure can be installed on the frame body, thereby improving the lightning protection function of the frame body.

[0016] Furthermore, rubber pads are installed at the locations where the lower and upper clamping plates contact the solar panels.

[0017] By adopting the above technical solution, the provision of the rubber pad can protect the solar cell panel and prevent the lower clamping plate and the upper clamping plate from scratching the solar cell panel.

[0018] Furthermore, the clamping posts are adapted to the clamping holes, and a plurality of the clamping posts are equidistantly distributed on one side of the movable plate.

[0019] By adopting the above technical solution, when the clamping column is clamped into the clamping hole, the upper clamping plate can be limited to prevent the upper clamping plate from moving.

[0020] Furthermore, the clamping column is slidably connected to the cavity via a movable plate.

[0021] By adopting the above technical solution, when the movable plate slides inside the cavity, it drives the clamping column to move, so that the clamping column moves into the inside of the guide column.

[0022] Furthermore, the length of the push rod is greater than the length of the clamping column, and the outer wall of the push rod is sleeved with an insulating sleeve.

[0023] By adopting the above technical solution, it is convenient for the user to press the push rod, so that the push rod can move and drive the movable plate to move.

[0024] Furthermore, the upper clamping plate is sleeved on the outer wall of the guide column, and the upper clamping plate is slidably connected to the sliding groove through a sliding bar.

[0025] By adopting the above technical solution, the guide column can guide the upper clamping plate so as to improve the stability of the upper clamping plate when it moves.

[0026] In summary, the present invention has the following beneficial effects:

[0027] When the lever is released, the spring will stretch the movable plate and the lever will move back into the slot, which will cause the lever to move into the slot and into the slot, thereby securing the lever to the desired position. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Specifically, the adjustment assembly 9 includes a guide post 901 mounted on the top of the lower splint 3 and a clamping hole 907 opened on both sides of the first through hole 13. A cavity 908 is opened inside the guide post 901, and a fixing plate 902 is provided inside the cavity 908. A plurality of springs 903 are installed on both sides of the fixing plate 902. When the upper splint 5 needs to be clamped on the frame body 1, the user can press the push rod 904 to move the push rod 904 into the cavity 908 and drive the movable plate 905 to move, so that The movable plate 905 squeezes the spring 903, the length of the push rod 904 is greater than the length of the clamping column 906, and the outer wall of the push rod 904 is sleeved with an insulating sleeve, which is convenient for the user to press the push rod 904 so that the push rod 904 can move and drive the movable plate 905 to move.
