[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figure 1 and Figure 2As shown, the tracking photovoltaic power generation device of this embodiment includes a column 1, a first support component 2, a second support component 3, a photovoltaic bracket 4, and a photovoltaic panel 5. The first support component 2 has a first connecting part 25 and a second connecting part 26. The first support component 2 is rotatably connected to the top of the column 1 through the first connecting part 25, and the first support component 2 is rotatable in a vertical plane. The second support component 3 has a third connecting part 32, which is connected to the second connecting part 26, so that the second support component 3 is rotatable relative to the first support component 2 in a first plane, which is orthogonal to the vertical plane. There are two photovoltaic brackets 4, both of which are connected to the second support component 3. The two photovoltaic brackets 4 are arranged in a centrally symmetrical manner on the second support component 3. The photovoltaic panel 5 is disposed on the two photovoltaic brackets 4.

[0039] In this embodiment of the invention, the bottom of the column 1 is supported on the pile foundation, and the top of the column 1 is used to fix the photovoltaic panel 5. In order to adjust the pitch angle and orientation of the photovoltaic panel 5, the arrangement of the first support component 2 in this embodiment of the invention allows the photovoltaic panel 5 and the second support component 3 to perform pitch swinging movements in the vertical plane. At the same time, the second support component 3 can be used to rotate the photovoltaic panel 5 in a plane that is roughly parallel to the horizontal plane to adjust the orientation of the photovoltaic panel 5. At this time, the photovoltaic panel 5 can be adjusted according to the angle of sunlight at different times of the day, or according to the direction of sunlight in high-latitude regions during different seasons each year, thereby improving the power generation efficiency.

[0040] The tracking photovoltaic power generation device of this invention can flexibly adjust its tilt angle and direction, and has strong adaptability to different sites.

[0041] In some embodiments, the first support assembly 2 includes a first frame 21, a rack 22, a drive gear 23, and a first driver 24. A first connecting part 25 is located below the middle of the first frame 21 and is connected to the column 1 via a first shaft 27. A second connecting part 26 is located above the first frame 21. The rack 22 is semi-circular, with both ends connected to the first frame 21. The rack 22 is coaxially arranged with the first shaft 27. The drive gear 23 is located on the column 1 and meshes with the rack 22. The first driver 24 is connected to the drive gear 23 in a transmission manner.

[0042] It should be understood that the first frame 21 is rotatably connected to the column 1 via the first shaft 27. The axis of the first shaft 27 is parallel to the horizontal plane. When the first frame 21 rotates relative to the column 1, the pitch adjustment of the second support component 3 and the photovoltaic panel 5 can be realized.

[0043] Furthermore, in order to control the rotation of the first frame 21, the embodiment of the present invention provides an arc-shaped rack 22 with teeth arranged on its outer periphery. The drive gear 23 is rotatably connected to the column 1. When the first driver 24 drives the drive gear 23 to rotate, the first frame 21 will rotate because the drive gear 23 meshes with the rack 22.

[0044] In this embodiment of the invention, the rack 22 has a larger radius and the drive gear 23 has a relatively smaller radius. Therefore, by setting a reasonable reduction ratio, the power of the first driver 24 can be reduced, and the pitch and swing angle of the photovoltaic panel 5 can be precisely adjusted, thereby improving the adjustment accuracy.

[0045] Optionally, the first driver 24 is a motor, which can adjust the photovoltaic panel 5 to flip up or down by rotating the motor forward and backward.

[0046] The output end of the motor is connected to the drive gear 23 via a coupling, or via a sprocket and chain for transmission.

[0047] In some embodiments, the first frame 21 is a first support plate, the first connecting part 25 is a column located below the first support plate, and the second connecting part 26 is a lower flange located above the second support plate.

[0048] The first frame 21 serves as an intermediate component between the second support assembly 3 and the column 1, and needs to be connected to the components above and below. Therefore, by setting the first frame 21 as a support plate, the space above and below can be better allocated, providing a more sufficient connection area and allowing for the reasonable arrangement of different components. The second connecting part 26 is set as a lower flange, which makes it easier to align and connect. The lower flange can be fixed to the support plate by welding.

[0049] Furthermore, the column 1 is provided with a through hole or through groove 11, and a section of the rack 22 passes through the through hole or through groove 11.

[0050] Through holes or U-shaped through slots 11 can also be provided on the column 1. The rack 22 is arranged through the through holes or through slots 11 so that the center of gravity of the first support component 2 is aligned with the column 1, avoiding the problem of center of gravity offset, which would cause the component to be unstable under force.

[0051] In some embodiments, the second support component 3 includes a second frame 31 and a third connection portion 32 disposed below the second frame 31; the tracking photovoltaic power generation device also includes a rotary table 33 disposed between the second connection portion 26 and the third connection portion 32.

[0052] The lower part of the rotary table 33 is connected to the lower flange, and the upper part of the rotary table 33 is connected to the third connecting part 32, which can be the upper flange. In this case, the rotary table 33 can be connected to the upper flange and the lower flange by bolts, which facilitates assembly.

[0053] Furthermore, the tracking photovoltaic power generation device also includes a second driver for driving the rotary table 33 to rotate, so that the second frame 31 rotates relative to the first support assembly 2.

[0054] The second driver is a motor, which drives the rotary table 33 to rotate, thereby allowing the second frame 31 to rotate relative to the first support component 2, so that the photovoltaic panel 5 can rotate in a plane (approximately horizontal plane) parallel to the second frame 31, adjusting the orientation of the photovoltaic panel 5.

[0055] Optionally, the rotary table 33 includes an inner ring and an outer ring, which are connected by bearings. The inner ring is connected to the second frame 31, and the outer ring is connected to the lower flange. The second driver is fixed on the second frame 31. A gear ring is provided on the outer circumference of the outer ring. A gear is provided at the output end of the second driver. The gear meshes with the gear ring, thereby driving the rotary body to rotate through the second driver.

[0056] In some embodiments, the tracking photovoltaic power generation device further includes a support roller 34, which is located below the second frame 31. There are multiple support rollers 34, which are arranged circumferentially around the turntable 33. The first frame 21 is provided with an annular roller track 35, and the support rollers 34 abut against the roller track 35.

[0057] The first frame 21 and the second frame 31 are supported by multiple support rollers 34, which can ensure the stability between the two, prevent the rotary table 33 from being deformed by excessive lateral force, and improve the stability of the equipment.

[0058] In some embodiments, the photovoltaic bracket 4 is fixedly connected to the second frame 31, and the included angle between the photovoltaic bracket 4 and the second frame 31 is 30° to 60°.

[0059] Specifically, the angle between the photovoltaic bracket 4 and the second frame 31 can be 30°, 33°, 35°, 45°, 50° or 60°, depending on the geographical location. When the angle between the photovoltaic bracket 4 and the second frame 31 is less than 30° or greater than 60°, the practicality is poor, and it is easy to cause the adjustment range of the first support component 2 or the second support component 3 to be too large in actual application, which will affect the stability of the equipment.

[0060] In some embodiments, the photovoltaic support 4 is rotatably connected to the second frame 31, and multiple connecting rods 41 are provided between the photovoltaic support 4 and the second frame 31.

[0061] It should be understood that the photovoltaic bracket 4 and the second frame 31 can be folded and stored during transportation, and unfolded and connected by the connecting rod 41 after arriving at the site, which facilitates transportation and can be finely adjusted according to different terrains, making it more practical.

[0062] Furthermore, the connecting rod 41 is a telescopic rod, and multiple connecting rods 41 are provided between each photovoltaic bracket 4 and the second frame 31 to adjust the angle between the photovoltaic bracket 4 and the second frame 31.

[0063] The telescopic rod can consist of two sleeves connected by threads. Once the length is adjusted to the correct position, it is secured using bolts or other connecting components.

[0064] Furthermore, the photovoltaic support 4 has a first side facing the sunlight, and the first side has a fourth connecting part, to which the photovoltaic panel 5 is connected. The fourth connecting part can be a connecting hole provided on the first side, and the photovoltaic panel 5 is fixed to the first side by bolts or other fasteners.

[0065] In some embodiments, the second frame 31 is a frame structure, and the second frame 31 includes multiple horizontal bars and multiple vertical bars, which are welded and fixed together.

[0066] Since the second frame 31 supports two photovoltaic brackets 4, which are arranged in parallel and symmetrically with respect to the second frame 31, and the second frame 31 has a first end and a second end, with one photovoltaic bracket 4 located above the first end and the other below the second end, the second frame 31 is designed as a frame structure to facilitate the arrangement of components such as the connecting rod 41, the second driver, and the rotary table 33. This facilitates the installation of components at its bottom, avoids interference between components, and improves installation efficiency. When arranging photovoltaic devices on slopes or islands with gradients, the devices are typically arranged in the east, west, south, and north directions. The photovoltaic devices are affected not only by the slope but also by their orientation on the slope or island, requiring individual initial position adjustments for different devices. Therefore, this embodiment of the invention can meet the requirements for adaptability of photovoltaic devices to terrain.
