Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and particularly relates to an integrated structure photovoltaic panel mounting clamp. Background Art

[0002] Photovoltaic panel clamps are key auxiliary accessories in a photovoltaic power generation system, mainly playing the role of fixing and stabilizing solar panels. Photovoltaic panel clamps can be divided into middle clamps and side clamps. The middle clamps are used to fix the connection between main components, while the side clamps are used to fix the main components and guide rails of photovoltaic brackets. Through the combined use of middle and side clamps, photovoltaic modules and brackets are firmly connected together to form a stable overall structure. This design can maintain the stability of the overall structure under strong loads, and there will be no obvious deformation even under strong loads.

[0003] In practical applications, there are clamps used to fix photovoltaic panels on color steel tiles. The bottom end of the clamp needs to be fixedly connected to the color steel tile, and the upper part is connected to the frame of the photovoltaic panel to complete the fixing function of the photovoltaic panel.

[0004] For example, the Chinese invention patent with the authorization announcement number CN117375498A: A Photovoltaic Panel Connection Device and a Photovoltaic Panel Installation Method. The photovoltaic panel connection device includes a clamp, a bolt, an adjusting plate, a first clip and a second clip; the lower end of the clamp is provided with a left pressing part and a right pressing part, and an installation groove is formed between the left pressing part and the right pressing part. The upper ends of the first clip, the second clip, and the adjusting plate are all arranged in the installation groove. The adjusting plate is located between the first clip and the second clip. One end of the adjusting plate is rotatably connected to the first clip, and the other end is rotatably connected to the second clip; a clamping groove is provided at the lower ends of the first clip and the second clip. The bolt passes through the clamp and the adjusting plate from above the clamp, and a nut is screwed at its lower end. By adjusting the position of the nut on the bolt, the adjusting plate moves up or down in the installation groove, driving the first clip and the second clip to rotate, so that the clamping grooves of the first clip and the second clip approach each other to clamp the convex rib at the upper end of the color steel tile or move away from each other to loosen the convex rib at the upper end of the color steel tile.

[0005] Although the above-mentioned utility model patent can use the clamp for the installation and fixation of the photovoltaic panel and the color steel tile, the installation process is cumbersome and the structure is complex. Therefore, there is an urgent need in the art for an integrated structure photovoltaic panel mounting clamp to solve the problems existing in the prior art. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an integrated structure photovoltaic panel mounting clamp to solve the above-mentioned deficiencies in the prior art.

[0007] To achieve the above object, the present utility model provides the following technical solution: An integrated structure photovoltaic panel mounting clamp, including a fixture disposed at the bottom end. The bottom end of the fixture is provided with a clamping opening. A second mounting hole is vertically opened on the top surface of the fixture.

Then clamp and connect the clamping end with the top protrusion of the color steel tile. Then use the third bolt and the third nut to lock the fixture to fix the fixture and the color steel tile firmly. Then insert the edge of the frame of the photovoltaic panel into the gap between the L-shaped extension plate and the upper clamping plate, and lock the second bolt and the first bolt to clamp and fix the frame of the photovoltaic panel. Use multiple pressing blocks to clamp and fix different edge parts of the frame of the photovoltaic panel respectively to achieve efficient and highly stable fixed installation of the frame of the photovoltaic panel.
