[0018] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0019] like Figure 1-3 The angle adjustment device for a photovoltaic support shown in the figure includes a bearing 3, a rotating shaft 2 matched with the inner ring of the bearing 3, and a fixing seat 1 matched with the outer ring of the bearing 3. The fixing seat 1 is fixed on the ground a, and the ground a is land or mountain. The rotation of the rotating shaft 2 can drive the inner ring of the bearing 3 to rotate, and the outer ring of the bearing 3 does not rotate. In this embodiment, the number of bearings 3 is two, and the driven gear 4 is located between the two bearings 3.

[0020] It also includes a driving gear 6 and a driven gear 4 that are meshed with each other, and a driving mechanism that drives the driving gear 6. The driving mechanism is a motor 5 installed on the fixed seat 1, and the driving gear 6 is installed on the output shaft 51 of the motor 5. The motor 5 drives the output shaft 51 to rotate forward and reverse, and the driving gear 6 rotates forward and reverse synchronously, thereby driving the driven gear 4 to rotate forward and reverse synchronously.

[0021] The driven gear 4 and the rotating shaft 2 are arranged vertically. The driven gear 4 and the rotating shaft 2 are connected. Specifically, the rotating shaft 2 is welded at the center of the driven gear 4. The rotating shaft 2 can rotate forward and reverse synchronously with the driven gear 4, so that the angle of the photovoltaic bracket 7 can be adjusted.

[0022] The driven gear 4 is fan-shaped with an angle of 120°, so that the adjustable angle range of the photovoltaic bracket 7 is set between 0°-120° and can be flexibly adjusted according to the incident direction of sunlight.

[0023] The driven gear 4 includes two side edges 41 at an angle, a first arc edge 42 and a second arc edge 43 connected between the two side edges 41 and arranged outward in sequence along the longitudinal direction, a first reinforcing rib 44 connecting the first arc edge 42 and the side edge 41, and a second reinforcing rib 45 connecting the first arc edge 42 and the second arc edge 43. The side edge 41, the first arc edge 42, the second arc edge 43, the first reinforcing rib 44, and the second reinforcing rib 45 are an integrated structure. The driven gear 4 is light in weight and has a strong support.

[0024] The second arc edge 43 is provided with teeth 431 meshing with the driving gear 6. A reinforcing strip 46 is also included, and the two ends of the reinforcing strip 46 are respectively welded to the second reinforcing rib 45 and the rotating shaft 2. The number of the reinforcing strips 46 is two and they are located on both sides of the driving gear 4.

[0025] The auxiliary support fixing mechanism 8 is also included, and the auxiliary support fixing mechanism 8 includes a telescopic rod 81 and a clamp 82 connected to the top of the telescopic rod 81. The bottom of the telescopic rod 81 is fixed on the ground a, and the ground a is land or mountain. There are two auxiliary support fixing mechanisms 8 and they are located at both ends of the rotating shaft 2.

[0026] The telescopic rod 81 retracts and the clamp 82 leaves the rotating shaft 2. When the angle of the photovoltaic bracket 7 is adjusted, the telescopic rod 81 extends to make the rotating shaft 2 fit into the clamp 82, and then the clamp 82 is locked, which plays a role in auxiliary support and fixing the position of the rotating shaft 2, thereby reducing the pressure between the driving gear 6 and the driven gear 4.

[0027] The photovoltaic panel 9 is installed on the photovoltaic bracket 7, which is an existing structure and will not be described in detail. The photovoltaic bracket 7 is connected to the rotating shaft 2, so that the photovoltaic bracket 7 can rotate synchronously with the rotating shaft 2, so that the angle of the photovoltaic bracket 7 can be adjusted.

[0028] In this embodiment, the photovoltaic bracket 7 and the rotating shaft 2 are connected by a connecting mechanism 71, and the connecting mechanism 71 includes two threaded columns 72 welded to the photovoltaic bracket 7, a pressing block 74, and a nut 73. The two threaded columns 72 and the pressing block 74 are tightly attached to the rotating shaft 2 to surround it. The pressing block 74 is provided with two through holes, and the threaded column 72 passes through the through holes and is fastened by the nut 73 to fix the rotating shaft 2, which is convenient for disassembly and assembly. Of course, the photovoltaic bracket 7 and the rotating shaft 2 can also be welded for long-term use.

[0029] The rotating parts involved in this patent need to be sealed in actual use to extend their service life.
