[0008] The purpose of the utility model is to provide a sprocket for a photovoltaic bracket. By improving the structure of the traditional sprocket, the problem of out-of-plane bending caused by too large a sprocket plate surface is solved, and welding is not required, so that the processing accuracy will not be affected by welding deformation.

[0009] To solve the above problems, the utility model provides a sprocket for a photovoltaic bracket, which includes a connection component, a main body part, and a tooth part.

[0025] The following description is only used to disclose the present utility model so that those skilled in the art can implement the present utility model.

[0026]

Embodiment 1

[0027] A sprocket for a photovoltaic bracket, as Figure 1 , includes a connection component, a main body part, and a tooth part. The connection component is used to connect with the main shaft. The main body part is connected to the connection component and the tooth part to form the main body of the sprocket. The main body part includes a plurality of rod bodies 4. The tooth part includes an arc-shaped chain tooth thick plate 6. The chain tooth thick plate 6 and the rod bodies 4, as well as between the rod bodies 4 and the connection component, are all connected in a non-welding manner.

[0028] Specifically, the connection component is a hoop, including an upper hoop 1 and a lower hoop 3. The upper hoop 1 and the lower hoop 3 are connected by bolts and tightened around the main shaft 2 to achieve fixation. There are two lower hoops 3 on the left and right. The lower hoop 3 has a rod body connection part that bends downward, as Figure 3 , and the rod body connection part and the rod body 4 are riveted by a second rivet 7.2. The rod body 4 is located between the two lower hoops 3 on both sides. A stabilizer 8 is also installed between the two lower hoops 3 on both sides. The stabilizer 8 connects the two lower hoops 3 on both sides to ensure the stability outside the plane of the lower hoop.

[0029] A plurality of rod bodies 4 replace the sprocket plate surface of the traditional sprocket, as Figure 1 , the rod body 4 includes a vertical rod and a horizontal rod. The connection between the horizontal rod and the vertical rod plays a strengthening effect. The stiffness outside the plane of the rod body is large, greatly reducing the out-of-plane deformation during the production, transportation, and operation of the sprocket system.

[0030] The chain tooth thick plate 6 is an arc-shaped plate body, and the outer side is the chain teeth. When power acts on the chain teeth, the sprocket drives the main shaft to rotate, realizing the tracking function of the photovoltaic bracket.

[0031] In this embodiment, as Figure 2 , the chain tooth thick plate 6 is composed of a plurality of chain tooth thin plates connected. The chain tooth thin plates are formed by stamping, with high efficiency. Multiple groups of chain tooth thin plates are riveted to form the chain tooth thick plate 6. The riveting technology is mature, and the strength of the riveted thick plate is not much different from that of directly using a thick plate.

[0032] It is not easy to have the problem of tooth surface inclination in thin plate stamping. Through die control, the requirements for personnel are low, solving the problems of high cost in laser cutting of the traditional sprocket body, difficult to ensure accuracy in flame cutting, and easy to generate tooth surface inclination in chain tooth stamping.

[0033] Furthermore, the tooth part further includes an arc-shaped U-shaped member 5. The U-shaped member 5 serves as the mounting bracket for the chain tooth thick plate 6 and can also play a role in improving the strength. For example, Figure 2 , the chain tooth thick plate 6 is installed in the U-shaped member 5. The U-shaped member 5 is riveted to the rod body 4. In this embodiment, two sets of chain tooth thick plates 6 are provided, and there is a gap between adjacent chain tooth thick plates 6, so as to form a stable transmission effect with the power system. In other embodiments, the number of chain tooth thick plates 6 can also be set to be greater than two sets.

[0034] Preferably, as Figure 2 , the chain tooth thin plate, the U-shaped member 5 and the rod body 4 are all riveted by the first rivet 7.1, reducing the number of components. In other embodiments, separate riveting methods can also be used for connection, such as riveting the chain tooth thin plates into the chain tooth thick plate 6, riveting the chain tooth thick plate 6 to the U-shaped member 5, and riveting the U-shaped member 5 to the rod body 4.

[0035] It should be noted that the above-mentioned riveting connection methods between the various structures can also use other non-welding connection methods, such as bolt connection.

[0036] Those skilled in the art should understand that the above description and the embodiments of the present invention shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively realized. The function and structural principle of the present invention have been shown and explained in the embodiments. Without departing from the said principle, the embodiments of the present invention can have any deformation and modification.
