A photovoltaic module is provided on the diagonal brace bracket. The installation grounding bracket further includes a horizontal support frame, a vertical metal frame, a metal grounding frame, and a grounding flat steel. A bracket installation through-hole is provided at a position near the top of the pipe pile column. The horizontal support frame passes through the bracket installation through-hole and its two ends are locked and limited by first locking bolts. One end of the diagonal brace bracket is fixed on the horizontal support frame and the other end is connected to the photovoltaic module. The top end of the vertical metal frame is rotatably connected to the photovoltaic module, and the bottom end of the vertical metal frame is inserted into the pipe pile column and contacts the horizontal support frame.

[0031] In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and defined, terms such as "arrangement" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components.

[0032] The embodiment provides a new type of photovoltaic module installation grounding bracket, as Figure 1 and Figure 2 shown, which includes a pipe pile column 1 and a diagonal bracing bracket 2. A photovoltaic module 3 is provided on the diagonal bracing bracket 2. The installation grounding bracket further includes a horizontal support frame 4, a vertical metal frame 5, a metal grounding frame 6, and a grounding flat steel 7.

[0033] In the embodiment, as Figure 8 and Figure 9 shown, the horizontal support frame 4 includes a first horizontal frame 400 and a second horizontal frame 401 with the same structure. One end of the two horizontal frames is provided with a diagonal bracing connection frame 402; as shown in 1 and Figure 7 shown, a bracket installation through hole 100 is opened at a position near the top of the pipe pile column 1; the cross-sectional area after overlapping the ends of the two horizontal frames without the diagonal bracing connection frame 402 matches the bracket installation through hole 100. The ends of the first horizontal frame 400 and the second horizontal frame 401 without the diagonal bracing connection frame 402 are symmetrically inserted from both sides of the bracket installation through hole 100, and after passing through the bracket installation through hole 100, they are fixedly locked with the diagonal bracing connection frame 402 on the other horizontal frame through a first locking bolt 8; since the width and thickness of the diagonal bracing connection frames 402 on both sides are greater than the bracket installation through hole 100, the horizontal frames can be limited by the diagonal bracing connection frames 402 at the ends of the two horizontal frames to prevent the horizontal frames from detaching from the pipe pile column, so that the horizontal support frame 4 can be stably installed on the pipe pile column 1; during the installation process of this horizontal support frame, the two horizontal frames will first pass through the bracket installation through hole 100 reserved on the pipe pile column 1, and then be fixedly connected through the first locking bolt 8. After the two horizontal frames are fixed, they can still move on both sides along the direction of their insertion. The design of this structure is very flexible, which can effectively eliminate the deviation influence caused by pipe pile construction, thus ensuring the precise installation and stability of the bracket. In order to enable the two horizontal frames to be matched and combined, a groove matching the other horizontal frame is provided on the diagonal bracing connection frame 402 of each horizontal frame, and they can be mutually engaged and then fixedly locked through the first locking bolt 8. In order to ensure the firm connection between the horizontal support frame 4 and the pipe pile column 1, after installation, a filler, such as a filler with a slightly expanding property, can also be injected into the reserved bracket installation through hole 100 to increase its stability.

[0034] A novel photovoltaic module installation grounding bracket is provided in the embodiment, such as Figure 1 As shown, the diagonal brace bracket 2 is provided with two, which are respectively installed at the diagonal brace connecting frame 402 of the first horizontal frame 400 and the second horizontal frame 401 through the fourth locking bolt 11. The other ends of the two diagonal brace brackets 2 are connected to the photovoltaic module 3, and the horizontal support frame 4 can withstand the pressure load generated by the diagonal brace; the vertical metal frame 5 is located in the middle of the two diagonal brace brackets 2, and its top end is rotatably connected to the photovoltaic module 3, and the bottom end of the vertical metal frame 5 is inserted into the pipe pile column 1 and contacts with the horizontal support frame 4; the vertical metal frame 5 is a metal square tube, and the first horizontal frame 400 and the second horizontal frame 401 are respectively provided with column limiting grooves 403 at the contact parts with the pipe pile column 1, and the horizontal support frame 4 can withstand the pressure load transmitted by the vertical metal frame 5. The horizontal support frame not only supports the weight of the photovoltaic module, but also ensures the stability of the entire system.

[0035] A novel photovoltaic module installation grounding bracket is provided in the embodiment, such as Figures 2 to 6 The metal grounding frame 6 is fixedly connected to the pipe pile column 1 and the vertical metal frame 5 through the second locking bolt 9, and the grounding flat steel 7 is fixed to the metal grounding frame 6 through the third locking bolt 10. The end of the second locking bolt 9 is provided with a first baffle 900 and a second baffle 901 which are parallel to each other, and the spacing between the first baffle 900 and the second baffle 901 is equal to or greater than the wall thickness of the vertical metal frame 5. Through holes matching the lengths of the two baffles are correspondingly opened on the vertical metal frame 5 and the pipe pile column 1. The first baffle 900 of the second locking bolt 9 sequentially passes through the through holes on the vertical metal frame 5 and the pipe pile column 1 and extends into the inner wall of the vertical metal frame 5. The second baffle 901 passes through the through hole on the pipe pile column 1 and is located on the outer wall of the vertical metal frame 5. After the two baffles are in place, the second locking bolt 9 can be rotated 90 degrees to make the two baffles perpendicular to the through holes to prevent them from falling off, and then they are locked and fixed by nuts. The two baffles at the front end of the second locking bolt 9 are similar to an I-shaped structure. The design of this structure can effectively fix the vertical metal frame 5 and the metal grounding frame 6 firmly on the pipe pile column 1. The vertical metal frame 5 is fixed by one bolt, and the metal grounding frame 6 is fixed, ensuring the grounding safety of the photovoltaic support assembly. At the same time, it can also eliminate the deviation caused by the pipe pile construction and ensure the stability and accuracy of the entire photovoltaic support. This design not only simplifies the installation process and improves the installation efficiency, but also increases the stability and safety of the entire photovoltaic system. In order to ensure a firm connection between the structure and the pipe pile column 1, after installation, a filler, such as a filler with a micro-expansion property, can also be injected into the through hole to strengthen the connection and prevent loosening.

[0036] In the embodiment, Figure 4As shown, the metal grounding frame 6 is an L-shaped metal support frame; the grounding flat steel 7 is fixed on the horizontal support plate of the metal grounding frame 6 through the third locking bolt 10, and a connecting piece 700 for connecting with the external grounding wire is provided at the outer end of the grounding flat steel 7. During the installation process, the connecting piece and the third locking bolt 10 work together to firmly fix the grounding flat steel 7 together, and the grounding flat steel 7 is made of galvanized flat steel. The vertical metal frame 5, the metal grounding frame 6 and the grounding flat steel 7 form a grounding structure, thereby effectively grounding the photovoltaic module structure to the ground and enhancing the safety of the system; moreover, the metal grounding frame 6 is simultaneously connected to the vertical metal frame 5 and the pipe pile column 1 through the second locking bolt 9, firmly connecting the entire photovoltaic module structure to the ground together, forming a stable and safe system as a whole.

[0037] The utility model combines the photovoltaic installation structure with the grounding structure, which not only helps to accurately position during the installation process, but also ensures the stability and reliability of the structure. Through the specific cooperation and connection methods of the two structures, the firm fixation of the column is jointly achieved, and the challenges brought by various environmental factors can be effectively coped with, fully considering the deviation problems that may occur in the pipe pile construction; through a reasonable adjustment and compensation mechanism, they can eliminate or reduce the influence of this deviation on the installation of the photovoltaic support assembly, ensuring the stability and safety of the entire system.

[0038] The above description is only an embodiment of the utility model, and its description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the appended claims.
