Description

Technical Field

[0001] This utility model relates to the field of photovoltaic facilities, and in particular to a photovoltaic tracking bracket. Background Technology

[0002] Photovoltaic tracking brackets are commonly used in photovoltaic systems. Patent publication document CN218570162U discloses a photovoltaic tracking bracket. This photovoltaic tracking bracket mainly relies on a first push rod and a second push rod to realize the swing of the photovoltaic panel. In this structure, since the first push rod and the second push rod are triangularly distributed, when the photovoltaic system shown in this structure drives the main shaft to rotate, as the rotation angle of the main shaft gradually increases, the length of the main shaft lever arm approaches the radius of the main shaft, resulting in very low driving efficiency. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a photovoltaic tracking bracket. Since the electric push rod is installed parallel to the column, the effective lever arm length of the electric push rod remains constant, ensuring that the electric push rod has relatively high driving efficiency.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A photovoltaic tracking bracket includes a column, a bearing, and a main shaft. The bearing is disposed at one end of the column, and the main shaft is rotatably mounted on the bearing. The bracket also includes a base plate and an electric push rod. The base plate is disposed at the other end of the column, and the electric push rod is fixedly mounted on the base plate. The electric push rod is parallel to the column. A pin hole is provided on the telescopic shaft of the electric push rod. A slide rod is directly or indirectly disposed on the main shaft. The slide rod is slidably engaged with the pin hole, and the diameter of the pin hole is larger than the diameter of the slide rod.

[0006] In this type of photovoltaic tracking bracket, a pin hole is opened on the telescopic shaft of the electric push rod, and a slide rod is set on the main shaft. The slide rod and the pin hole are slidably engaged. When the telescopic shaft of the electric push rod extends or retracts, the telescopic shaft can drive the main shaft to rotate through the slide rod. When the main shaft rotates, it can drive the photovoltaic panel to rotate. Since the electric push rod is installed parallel to the column, the effective lever arm length of the electric push rod is kept constant, which can ensure that the electric push rod has a relatively high driving efficiency.

[0007] In this type of photovoltaic tracking bracket, the diameter of the pin hole is larger than the diameter of the slide rod, so that the slide rod can slide smoothly relative to the pin hole during the rotation of the main shaft. Specifically, in order to ensure that the main shaft can rotate at a large angle, the pin hole can be an oval-shaped pin hole. When the main shaft rotates, the cylindrical slide rod slides in the oval-shaped pin hole.

[0008] In summary, because the electric actuator is installed parallel to the column in this type of photovoltaic tracking bracket, the effective lever arm length of the electric actuator remains unchanged, which ensures that the electric actuator has a relatively high driving efficiency.

[0009] Optionally, it also includes a mounting plate and a clamping plate, the mounting plate and the clamping plate being fitted together, the spindle being clamped between the mounting plate and the clamping plate, and the slide rod being disposed on the mounting plate.

[0010] The mounting plate and the clamping plate are fixed together, and the sliding rod is fixed on the mounting plate.

[0011] Optionally, one end of the electric push rod is provided with a flange, which is fitted together with the base plate.

[0012] Optionally, it also includes purlins, which are disposed on the main shaft, and photovoltaic panels are disposed on the purlins.

[0013] The purpose of purlins is to install photovoltaic panels.

[0014] Optionally, the purlin is perpendicular to the main shaft, and the photovoltaic panel is not in contact with the main shaft.

[0015] Optionally, a pressure block is provided between two adjacent photovoltaic panels.

[0016] The function of the clamping block is to separate and fasten the photovoltaic panels.

[0017] Optionally, it also includes a base, which is disposed on one side of the base plate, and the base and the column are respectively located on both sides of the base plate.

[0018] Optionally, the spindle includes a square tubular spindle.

[0019] The beneficial effects of this utility model are: since the electric actuator is installed parallel to the column, the effective lever arm length of the electric actuator remains unchanged, which can ensure that the electric actuator has a relatively high driving efficiency.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0027] As attached Figure 1 and appendix Figure 2 As shown, a photovoltaic tracking bracket includes a column 13, a bearing, and a main shaft 11. The bearing is located at one end of the column 13, and the main shaft 11 is rotatably mounted on the bearing. The bracket also includes a base plate 3 and an electric push rod 5. The base plate 3 is located at the other end of the column 13, and the electric push rod 5 is fixedly mounted on the base plate 3. The electric push rod 5 is parallel to the column 13. A pin hole 502 is provided on the telescopic shaft 501 of the electric push rod 5. A slide rod 6 is directly or indirectly provided on the main shaft 11. The slide rod 6 is slidably engaged with the pin hole 502, and the diameter of the pin hole 502 is larger than the diameter of the slide rod 6.

[0028] In this type of photovoltaic tracking bracket, a pin hole 502 is opened on the telescopic shaft 501 of the electric push rod 5, and a slide rod 6 is provided on the main shaft 11. The slide rod 6 is slidably engaged with the pin hole 502. When the telescopic shaft 501 of the electric push rod 5 extends or retracts, the telescopic shaft 501 can drive the main shaft 11 to rotate through the slide rod 6. When the main shaft 11 rotates, it can drive the photovoltaic panel 2 to rotate. Since the electric push rod 5 is installed parallel to the column 13, the effective lever arm length of the electric push rod 5 is kept constant, which can ensure that the electric push rod 5 has a relatively high driving efficiency.

[0029] In this type of photovoltaic tracking bracket, the diameter of the pin hole 502 is larger than the diameter of the slide rod 6. Therefore, during the rotation of the main shaft 11, it can be ensured that the slide rod 6 slides smoothly relative to the pin hole 502. Specifically, in order to ensure that the main shaft 11 can rotate at a large angle, the pin hole 502 can be an oval-shaped pin hole 502. When the main shaft 11 rotates, the cylindrical slide rod 6 slides in the oval-shaped pin hole 502.

[0030] In summary, since the electric push rod 5 is installed parallel to the column 13 in this type of photovoltaic tracking bracket, the effective lever arm length of the electric push rod 5 remains unchanged, which ensures that the electric push rod 5 has a relatively high driving efficiency.

[0031] As attached Figure 1 and appendix Figure 2 As shown, it also includes a mounting plate 12 and a clamping plate 10. The mounting plate 12 and the clamping plate 10 are fitted together, the spindle 11 is clamped between the mounting plate 12 and the clamping plate 10, and the slide rod 6 is set on the mounting plate 12.

[0032] Mounting plate 12 and clamping plate 10 are clamped together in a fixed fit, and sliding rod 6 is fixed on mounting plate 12.

[0033] As attached Figure 1 and appendix Figure 2 As shown, one end of the electric push rod 5 is provided with a flange 4, which is fitted together with the base plate 3.

[0034] As attached Figure 1 and appendix Figure 2 As shown, it also includes purlins 8, which are mounted on the main shaft 11, and photovoltaic panels 2 are mounted on purlins 8.

[0035] The function of purlin 8 is to install photovoltaic panel 2.

[0036] As attached Figure 1 and appendix Figure 2 As shown, the purlin 8 is perpendicular to the main shaft 11, and the photovoltaic panel 2 is not in contact with the main shaft 11.

[0037] As attached Figure 1 and appendix Figure 2As shown, a pressure block 7 is set between two adjacent photovoltaic panels 2.

[0038] The function of the pressure block 7 is to separate and fasten the photovoltaic panel 2.

[0039] As attached Figure 1 and appendix Figure 2 As shown, it also includes a base 1, which is located on one side of the base plate 3. The base 1 and the column 13 are located on the two sides of the base plate 3, respectively.

[0040] The base 1 and the column 13 are on a straight line, and both the column and the base are perpendicular to the base plate 3.
