Description

Technical Field

[0001] This utility model relates to the photovoltaic field, and in particular to the connection structure between photovoltaic modules and C-shaped steel. Background Technology

[0002] Solar photovoltaic (PV) brackets are special supports designed for placing, installing, and fixing solar panels in a solar PV power generation system. Carbon steel PV brackets primarily use C-shaped steel sections as the support structure for each fulcrum. The part of the PV module that directly contacts the bracket is called the purlin. However, currently, the main method of fixing the module to the purlin is to drill long holes in the side of the purlin and use studs and nuts for fixing. This fixing method leads to excessively high production costs for small batches of C-shaped steel in various specifications. Other clamping methods that do not require drilling also have the following problems due to the diverse specifications of C-shaped steel sections: 1. The thickness of C-shaped steel varies depending on the required strength. Most clamping methods on the market that do not require drilling involve inserting the C-shaped steel into a clamping slot. This fixing method has high requirements for the matching of the slot and the thickness of the C-shaped steel; if it is too thick, it cannot be inserted; if it is too thin, the gap is too large and it is prone to wobbling. 2. For clamping methods that are fixed on one side through the slot, the tensile strength provided is usually low, making them unusable in applications with high loads. However, products on the market that use double slots for fixing are often incompatible with the wide variety of C-shaped steel specifications. Therefore, a more versatile product is needed that can accommodate various C-shaped steel heights and thicknesses. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a card block that can be adapted to C-shaped steel of different specifications for installation.

[0004] To solve the above-mentioned technical problems, this utility model provides a clip that can be adapted to various C-shaped steel specifications, including: a first part and a second part arranged along the height direction of the C-shaped steel, the first part and the second part having an overlapping area, the overlapping area being provided with a strip hole along the height direction of the C-shaped steel; a fixing member passing through the strip hole to fix the first part and the second part.

[0005] The height of the card block is changed by adjusting the relative positions of the first and second parts in the height direction of the C-shaped steel to adjust the area of ​​the overlapping region.

[0006] In a preferred embodiment: the first part and the second part have a slot on opposite sides that engages with the C-shaped steel.

[0007] In a preferred embodiment: the inner wall of the slot has wavy protrusions.

[0008] In a preferred embodiment: the fastener includes a stud and a nut, one end of the stud passing through the slot and being fixed to the nut.

[0009] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0010] This utility model provides a clamping block that can be adapted to various C-shaped steel specifications. The overall height of the clamping block can be adjusted by changing the relative position of the first part and the second part, thereby adapting to various C-shaped steel height specifications. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the installation of the card block in a preferred embodiment of the present invention. Detailed Implementation

[0012] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0013] refer to Figure 1 This embodiment provides a clip that can be adapted to various C-shaped steel specifications, including: a first part 21 and a second part 22 arranged along the height direction of the C-shaped steel 1, the first part 21 and the second part 22 having an overlapping area 211, 221, the overlapping area 211, 221 being provided with a strip hole 23 along the height direction of the C-shaped steel 1; a fixing member 24 passing through the strip hole 23 and fixing the first part 21 and the second part 22;

[0014] The height of the card block is changed by adjusting the relative positions of the first part 21 and the second part 22 in the height direction of the C-shaped steel 1 to adjust the area of ​​the overlapping areas 211 and 221.

[0015] The aforementioned clamping block, which can be adapted to various C-shaped steel 1 specifications, can adjust the overall height of the clamping block by changing the relative position of the first part 21 and the second part 22, thereby adapting to various C-shaped steel 1 height specifications.

[0016] Furthermore, to allow the first part 21 and the second part 22 to engage with the C-shaped steel 1, the first part 21 and the second part 22 have engaging grooves 212 and 222 on opposite sides for engaging with the C-shaped steel 1, and the inner walls of the engaging grooves 212 and 222 have wavy protrusions. These wavy protrusions increase the friction between the inner walls of the engaging grooves 212 and 222 and the C-shaped steel 1, improving assembly stability. Additionally, the end faces of the first part 21 and the second part 22 abut against the inner wall surface of the C-shaped steel 1, further increasing installation stability.

[0017] In this embodiment, the fastener 24 includes a stud 241 and a nut 242. One end of the stud 241 passes through the strip hole 23 and is fixed to the nut 242.

[0018] In addition, in the above structure, the C-shaped steel 1 is set at the bottom of the photovoltaic module 3 as a supporting structure, and the upper end of the first part 21 extends horizontally to form a platform 25 that abuts against the bottom of the photovoltaic module 3. This platform 25 is fixed to the bottom of the photovoltaic module 3 by bolts 26.

[0019] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
