[0002] Existing photovoltaic power generation devices usually use photovoltaic tracking brackets to support and fix photovoltaic modules. The photovoltaic main beams on the photovoltaic tracking brackets can drive the photovoltaic modules to rotate with the movement of the sun to ensure that sunlight shines on the photovoltaic modules as vertically as possible, thereby improving power generation efficiency.

[0003] Under strong wind conditions, due to the large area of ​​the photovoltaic modules, the photovoltaic modules need to withstand a large wind load. When the wind load is transmitted to the photovoltaic bracket, it generates a large force on the photovoltaic bracket, which puts a great test on the structural stability. At present, most of the self-locking and dampers of the driving device on the photovoltaic tracking bracket are relied upon to resist strong winds, and the actual use effect needs to be improved.

The present invention will be further elaborated below in conjunction with specific implementation methods. Example 1

[0031] like Figure 1-Figure 5 As shown, a bearing seat for a photovoltaic tracking bracket includes a first half seat 1 and a second half seat 2 that are combined and connected. The first half seat 1 and the second half seat 2 are combined to form a bearing seat, for example, they are connected by a hinge at one end and locked at the other end by a screw. The bearing seat is used to install a photovoltaic bearing 18. A photovoltaic main beam 16 is installed through the photovoltaic bearing 18. A protrusion 17 is provided on the photovoltaic main beam 16. The first half seat 1 and the second half seat 2 are both composed of a semicircular plate 10, a blocking portion 11, and a brake baffle 3. The brake baffle 3 extends inward from the semicircular plate 10. A brake portion 4 is formed on the brake baffle 3 at one end away from the semicircular plate 10. The brake portion 4 is used to cooperate with the protrusion 17 on the photovoltaic main beam 16 to play a braking role when the photovoltaic main beam 16 moves to the extreme position.

[0032] Specifically, if Figure 6 、 Figure 7 As shown, the cross-section of the photovoltaic main beam 16 is set to be diamond-shaped, and the photovoltaic main beam 16 and the raised portion 17 are integrally formed. The raised portions 17 are symmetrically arranged on the two diagonals of the photovoltaic main beam 16, and the photovoltaic bearing 18 is sleeved on the photovoltaic main beam 16 and installed in the bearing seat. When the photovoltaic tracking bracket rotates, the photovoltaic main beam 16 rotates accordingly, and the photovoltaic bearing 18 rotates synchronously with the photovoltaic main beam 16 inside the bearing seat. When the photovoltaic main beam 16 rotates to the extreme angle or position, the raised portion 17 contacts the braking portion 4 on the brake baffle 3, and the braking portion 4 on the brake baffle 3 prevents the photovoltaic main beam 16 from continuing to rotate beyond the extreme position, thereby playing a role of position limiting protection.

[0033] The above-mentioned limit positions or limit angles may be tracking angles of common tracking brackets on the market, such as ±60° and ±45°.

[0034] In some optional embodiments, the blocking portion 11 and the brake baffle 3 are symmetrically arranged on the semicircular plate 10. After the photovoltaic bearing 18 is installed, the blocking portion 11 and the brake baffle 3 form an enclosing structure from the edge of the photovoltaic bearing 18. The blocking portion 11 cooperates with the brake baffle 3 to prevent the photovoltaic bearing 18 from falling off.

[0035] In some optional embodiments, the braking part 4 is composed of a first fitting part 12, a connecting part 13, and a second fitting part 14. The first fitting part 12 and the second fitting part 14 are connected by the connecting part 13, and contact the first fitting part 12 or the second fitting part 14 when the photovoltaic main beam moves to the extreme position.

[0036] Specifically, when the photovoltaic main beam 16 rotates to the extreme angle or position, the raised portion 17 contacts the first fitting portion 12 or the second fitting portion 14 on the braking portion 4, and the first fitting portion 12 or the second fitting portion 14 on the braking portion 4 prevents the photovoltaic main beam 16 from continuing to rotate beyond the extreme position, thereby playing a role of position limiting protection. When determining the contours of the first fitting portion 12 and the second fitting portion 14, it can be determined based on the position of the raised portion 17 when the photovoltaic main beam 16 rotates to the extreme position, and finally the first fitting portion 12 and the second fitting portion 14 are connected through the connecting portion 13.

[0037] In some optional embodiments, the semicircular plates 10 on the first half seat 1 and the second half seat 2 are combined to form a circular ring structure.

[0038] In some optional embodiments, the first half seat 1 is fixedly connected to the left and right ends of the bottom with first ear plates 5 , and the second half seat 2 is fixedly connected to the left and right ends of the top with second ear plates 6 .

[0039] Furthermore, the first ear plate 5 and the second ear plate 6 are spaced apart from each other, and a connecting hole 15 is provided on each of the first ear plate 5 and the second ear plate 6 . The first ear plate 5 and the second ear plate 6 are connected by a screw 9 .

[0040] More specifically, the screw rod 9 passes through the first ear plate 5 and the second ear plate 6 through the connecting hole 15, and the other end is locked by a nut, and a cotter pin is also installed on the outside of the nut.

[0041] In some optional embodiments, a bearing seat mounting seat 7 is fixedly connected to the bottom of the second half seat 2, a waist-shaped mounting hole 8 is provided at the bottom of the bearing seat mounting seat 7, and a connecting seat 19 for mounting the bearing seat is fixedly connected to the top of the column 19. The bearing seat is fixedly connected to the connecting seat 19 through the waist-shaped mounting hole 8, which facilitates the adjustment of the installation position.

[0042] In some optional embodiments, the first half seat 1 and the second half seat 2 are both integrally formed by casting.

[0043] In some optional embodiments, the thickness of the brake baffle 3 is set to 0.4-2 cm, and a suitable thickness is selected according to the load of the photovoltaic main beam 17.

[0044] In some optional embodiments, the blocking portion 11 extends inward from the semicircular plate 10, and the length of the blocking portion 11 extending out of the semicircular plate 10 is set to 0.3-3 cm. The length of the blocking portion 11 extending out of the semicircular plate 10 is determined based on the principle of being able to prevent the photovoltaic bearing 18 from falling off during rotation and not interfering with the movement of the photovoltaic main beam 16. Example 2

[0045] like Figure 8-Figure 9 As shown, the photovoltaic main beam 16 is set as a common round tube main beam on the market. A protrusion 17 with a triangular prism structure is provided on the photovoltaic main beam 16. The protrusion 17 is fixedly connected to the photovoltaic main beam 16 by bolts. When the photovoltaic tracking bracket rotates, the photovoltaic main beam 16 rotates accordingly, and the photovoltaic bearing 18 rotates synchronously with the photovoltaic main beam 16 inside the bearing seat. When the photovoltaic main beam 16 rotates to the extreme angle or position, the protrusion 17 contacts the braking part 4 on the brake baffle 3, and the braking part 4 on the brake baffle 3 prevents the photovoltaic main beam 16 from continuing to rotate beyond the extreme position, thereby playing a role of limiting protection.

[0046] Furthermore, when the photovoltaic main beam 16 rotates to the extreme angle or position, the raised portion 17 contacts the first fitting portion 12 or the second fitting portion 14 on the braking portion 4, and the first fitting portion 12 or the second fitting portion 14 on the braking portion 4 prevents the photovoltaic main beam 16 from continuing to rotate beyond the extreme position, thereby playing a role of limiting protection.

[0047] In addition, when the photovoltaic tracking bracket encounters strong wind conditions, the brake baffles 3 on the multiple bearing seats on the multiple columns can form multiple braking points, thereby providing better protection against strong winds and improving the structural strength of the overall photovoltaic tracking bracket.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
