Abstract
Description
Technical Field
[0001] The utility model relates to a photovoltaic tracking bracket system, belonging to the technical field of photovoltaic. Background Art
[0002] In related technologies, in order to obtain better wind pressure resistance, screen plates are arranged at both ends of a photovoltaic module. When wind enters the edge area of the photovoltaic module plate, the through holes on the screen plates have a guiding effect on the wind, enabling the wind to pass through the through holes, which can effectively promote the downstream flow, make the wind pressure distribution more balanced, and further enable the turbulence generated in this edge area to be effectively consumed through the screen plates, so that the wind after passing through will no longer generate turbulence, reducing the wind load at the edge of the photovoltaic module plate.
[0003] The photovoltaic modules of the photovoltaic tracking bracket will rotate to different angles at different times. The screen plates fixed on the main shaft are likely to interfere with other components, so they can only be installed at both ends of the main shaft. The installation position of the screen plates is limited and cannot achieve a good wind resistance effect. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a photovoltaic tracking bracket system with good wind pressure resistance.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a further improved technical solution of the utility model, the purlins include two first purlins adjacent to both axial sides of the driving mechanism. The connecting component includes a connecting seat and a rotating shaft. The connecting seat is installed on the first purlin.

[0009] As a further improved technical solution of the present utility model, the connecting seat includes a first side plate, a second side plate opposite to the first side plate, and a bottom plate connecting the first side plate and the second side plate. Both the first side plate and the second side plate are provided with shaft holes, and the bottom plate is connected to the first purlin.
[0010] As a further improved technical solution of the present utility model, the connecting component includes a torsion spring. The torsion spring includes a torsion spring body, a first end portion, and a second end portion. The first end portion and the second end portion are respectively connected to different ends of the torsion spring body. The torsion spring body is sleeved on the rotating shaft. The first end portion is connected to the connecting seat, and the second end portion is connected to the support rod.
[0011] As a further improved technical solution of the present utility model, the two connecting seats are correspondingly connected to the first purlins on both sides of the spoiler.

[0015] As a further improved technical solution of the present utility model, a sealing edge component is provided at one end of the spoiler away from the connecting seat, and the linkage rod is provided with a rod sleeve for the sealing edge component to abut against.
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: Utilizing the characteristic that it is not suitable to install photovoltaic modules above the driving device of the photovoltaic tracking bracket, the spoiler is rotatably arranged on the main shaft or purlin above the driving device.

[0030] Please refer to Figures 1 to 10 As shown, this utility model discloses a photovoltaic tracking bracket system, which includes a photovoltaic tracking bracket 1, a spoiler 2, and a connecting component 3. The photovoltaic tracking bracket 1 is used to support a plurality of photovoltaic panels 10, and the spoiler 2 is connected to the photovoltaic tracking bracket 1 through the connecting component 3.
[0031] See Figure 5 , the photovoltaic tracking bracket 1 includes a main shaft 11, purlins, and a driving mechanism. A plurality of photovoltaic panels 10 are installed on the main shaft 11 through the purlins, and the driving mechanism can drive the main shaft 11 to rotate to adjust the rotation of the photovoltaic panels 10 following the sun's movement trajectory. On some photovoltaic tracking brackets 1 using a slewing drive mechanism, in order to avoid interference between the photovoltaic panels 10 and the photovoltaic tracking bracket 1, photovoltaic panels 10 are usually not provided above the driving mechanism. The driving mechanism is a worm and gear structure, which belongs to the prior art and will not be described in detail here.
[0032] See Figure 7 and Figure 8 , the spoiler 2 includes a spoiler plate 21 and a support rod 22, and the spoiler plate 21 is connected to the support rod 22. The spoiler plate 21 is a perforated plate. The support rod 22 is a square tube structure.
[0033] See Figures 7 to 10, the connecting component 3 includes a connecting seat 31 and a rotating shaft 32. The rotating shaft 32 is connected to the connecting seat 31, and the spoiler 2 is rotatably connected to the rotating shaft 32. The axis of the rotating shaft 32 is parallel to the axis of the main shaft 11. Specifically, the purlin includes two first purlins 12 arranged adjacent to both axial sides of the driving mechanism. The connecting seat 31 is installed on the first purlin 12, and the support rod 22 of the spoiler 2 is rotatably connected to the connecting seat 31 through the rotating shaft 32. Two adjacent photovoltaic panels can be installed on the first purlin 12, and usually no photovoltaic panel 10 is provided above the driving mechanism. Therefore, a part of the first purlin 12 is still not utilized. This solution takes advantage of this feature and directly installs the connecting seat 31 on the first purlin 12, so that the spoiler 2 is located above the driving mechanism. In other embodiments, the connecting seat 31 can also be installed on the main shaft 11 through the connecting component 3. By arranging the spoiler 2 between two adjacent photovoltaic panels 10, the spoiler 2 can rotate relative to the photovoltaic panels 10, which can not only avoid interference between the spoiler 2 and the photovoltaic tracking bracket 1, but also enable this position to have better wind resistance, which is beneficial to withstanding strong winds.
[0034] The support rod 22 of the spoiler 2 and the rotating shaft 32 can be directly connected or indirectly connected. In some embodiments, refer to Figure 10 , the connecting component 3 includes a bushing 33. The connecting seat 31 has a shaft hole 310. The rotating shaft 32 at least partially passes through the bushing 33, and the bushing 33 passes through the shaft hole 310. The support rod 22 of the spoiler 2 is rotatably connected to the bushing 33, realizing the indirect connection between the support rod 22 of the spoiler 2 and the rotating shaft 32. By arranging the bushing 33 between the rotating shaft 32 and the support rod 22, and the bushing 33 is made of copper, the bushing 33 has the characteristic of wear resistance and prolongs the service life.
[0035] Specifically, the connecting seat 31 is of a U-shaped structure. Refer to Figure 10 , the connecting seat 31 includes a first side plate 311, a second side plate 312 opposite to the first side plate 311, and a bottom plate 313 connecting the first side plate 311 and the second side plate 312. Both the first side plate 311 and the second side plate 312 are provided with shaft holes 310. The rotating shaft 32 passes through the shaft holes 310 of the first side plate 311 and the second side plate 312 at the same time, and the bottom plate 313 is fixedly connected to the first purlin 12. Correspondingly, shaft sleeves 33 are provided in the shaft holes 310 of the first side plate 311 and the second side plate 312.
[0036] Refer to Figure 9 and Figure 10, the connecting component 3 further includes a torsion spring 34. The torsion spring 34 includes a torsion spring body 341, a first end 342, and a second end 343. The first end 342 and the second end 343 are respectively connected to different ends of the torsion spring body 341. The torsion spring body 341 is disposed through the rotating shaft 32. The first end 342 is connected to the connecting seat 31, and the second end 343 is connected to the support rod 22. The function of the torsion spring 34 is to keep the spoiler 2 level with the photovoltaic panel 10. When the rotating angle of the photovoltaic panel 10 is too large, it can prevent the spoiler 2 from rotating in the reverse direction and falling off under the action of gravity.
[0037] In the illustrated embodiment of the present utility model, two connecting seats 31 are correspondingly connected to the first purlins 12 on both sides of the spoiler 21; support rods 22 are provided on both sides of the spoiler 21. The two support rods 22 are correspondingly connected to the two connecting seats 31, and the two connecting seats 31 are correspondingly connected to the two first purlins 12. The two first purlins 12 are both located between two adjacent photovoltaic panels 10, so that the spoiler 2 can rotate stably around the photovoltaic tracking bracket 1.
[0038] See Figure 8 , a support 5 is provided on the side of the spoiler 2 close to the first purlin 12. The support 5 is used to abut against the first purlin 12. The support 5 is used to lift the spoiler 2, so that the spoiler 2 can be parallel to the photovoltaic panel 10, and the contact area between the spoiler 2 and the first purlin 12 can also be reduced.
[0039] See Figure 9 , the support 5 is of a U-shaped structure. The support 5 is connected to the support rod 22. The support 5 has a space for the support rod 22 to pass through. The support 5 and the support rod 22 are connected by fasteners. Specifically, the support 5 includes two side wall portions 51 and a bottom wall portion 52 connecting the two side wall portions 51. There is a gap between the bottom wall portion 52 and the support rod 22. The bottom wall portion 52 is used to contact the first purlin 12.
[0040] In some embodiments, see Figure 5 , the spoiler 2 includes a first spoiler 2a and a second spoiler 2b. The first spoiler 2a and the second spoiler 2b are rotatably connected to the same connecting seat 31, and the first spoiler 2a and the second spoiler 2b are connected to both sides of the same connecting seat 31 in the length direction. The length direction of the connecting seat 31 is parallel to the length direction of the first purlin 12, that is, the first spoiler 2a and the second spoiler 2b are respectively located on both sides of the radial direction of the main shaft 11. By providing the first spoiler 2a and the second spoiler 2b, the spoiler effect can be improved and the wind pressure resistance can be enhanced. In other embodiments, the spoiler 2 may also include only the first spoiler 2a or the second spoiler 2b.
[0041] The photovoltaic tracking bracket 1 can be arranged in one row or two rows. In the illustrated embodiment of the present utility model, see Figure 3 and Figure 5, the photovoltaic tracking bracket system includes two rows of interconnected photovoltaic tracking brackets 1 and a linkage rod 4 connecting the two rows of photovoltaic tracking brackets 1. The two ends of the linkage rod 4 are respectively connected to the driving mechanisms of adjacent two rows of photovoltaic tracking brackets 1. Each row of photovoltaic tracking brackets 1 is provided with a spoiler 2, and the spoiler 2 is arranged above the linkage rod 4. By arranging the spoiler 2 between adjacent two photovoltaic panels 10 and connecting it to the first purlin 12 through the connecting component 3, when the spoiler 2 rotates following the photovoltaic panel 10, since the spoiler 2 can rotate around the first purlin 12, interference between the spoiler 2 and the linkage rod 4 due to excessive rotation angle can be avoided. For example, the spoiler 2 maintains the same angle as the photovoltaic panel 10 before touching the linkage rod 4. When rotated to a certain angle and the spoiler 2 touches the linkage rod 4, the spoiler 2 will continuously stay above the linkage rod 4 and will not cause great pressure on the linkage rod 4.
[0042] See Figure 6 , a sealing edge component 6 is provided at one end of the spoiler 2 away from the connecting seat 31, and the linkage rod 4 is provided with a rod sleeve 7 for the sealing edge component 6 to abut against. Both the sealing edge component 6 and the rod sleeve 7 are made of plastic to achieve anti-wear protection for the spoiler 2 and the linkage rod 4.

The understanding of the present invention should be based on those skilled in the art of the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the relevant technical field can still modify the present invention or make equivalent replacements. All technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
