Description

Technical Field

[0001] This application relates to the field of photovoltaic bracket technology, and in particular to a torque tube and drive mechanism assembly and a photovoltaic tracking bracket. Background Technology

[0002] Photovoltaic tracking brackets are one of the more effective methods to improve photovoltaic power generation efficiency and reduce construction costs. Under the same irradiance conditions, by adjusting the angle of the photovoltaic modules, the automatic angle adjustment mode of the photovoltaic tracking bracket can absorb more solar radiation energy than fixed-installed photovoltaic modules, thereby achieving the goal of reducing photovoltaic power generation costs.

[0003] Currently, the torque tube is either sleeved on the outside of the driver's output shaft or plugged inside the driver's output shaft, and then the torque tube is connected to the driver by bolts. When the torque tube is subjected to a large torque, a certain amount of rotational slippage will occur between the torque tube and the output shaft, causing different rotation angles of the entire row of brackets in the length direction (axial direction), resulting in unevenness of the components on the entire row of brackets and affecting the overall safety of the brackets.

[0039] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0040] like Figures 1-5 As shown, in a first aspect, embodiments of this application may provide a torque tube and drive mechanism assembly, which may include:

[0041] Drive mechanism 1, drive mechanism 1 has output shaft 2, output shaft 2 has a first mounting groove 21;

[0042] A torque tube 3 is provided with a support plate 31, which is disposed in the first mounting groove 21; and the side wall of the support plate 31 abuts against the inner side wall of the first mounting groove 21.

[0043] A connecting assembly for connecting the support plate 31 and the output shaft 2.

[0044] In this embodiment, a support plate 31 is provided on the torque tube 3, placed in the first mounting groove 21, and then fixed to the output shaft 2 by a connecting assembly, so that the side wall of the support plate 31 abuts against the inner side wall of the first mounting groove 21. The support plate 31 is confined in the first mounting groove 21. Due to the large contact area between the support plate 31 and the inner side wall of the first mounting groove 21, when the torque tube 3 rotates, the inner side wall of the first mounting groove 21 can provide a supporting force to the support plate 31, counteracting the force generated by the rotation of the torque tube 3 and reducing the mutual rotational slippage between the torque tube 3 and the output shaft 2. Furthermore, the cooperation between the side wall of the support plate 31 and the inner side wall of the first mounting groove 21 can limit the rotation of the torque tube 3, effectively reducing the tendency of relative rotational slippage between the torque tube 3 and the output shaft 2, improving its torsional resistance, and reducing the axial torsional angle difference of the torque tube 3 caused by relative rotational slippage, thereby improving the flatness of the overall bracket and thus improving the overall safety performance of the bracket.

[0045] It should be noted that this embodiment does not limit the positions of the support plate 31 and the first mounting groove 21. Theoretically, when the support plate 31 is located inside the torque tube 3 and the first mounting groove 21 is located outside the output shaft 2, the torque tube 3 can be fitted onto the outside of the output shaft 2 for installation and fixation. When the support plate 31 is located outside the torque tube 3 and the first mounting groove 21 is located inside the output shaft 2, the torque tube 3 can be inserted into the inside of the output shaft 2 for installation and fixation.

[0046] In an optional embodiment, the torque tube 3 has a cavity 33, and a portion of the output shaft 2 is disposed in the cavity 33; a support sub-plate 32 protrudes from the side of the support plate 31 away from the cavity 33; a first clearance groove 321 is formed on the side of the support sub-plate 32 facing the cavity 33; a connecting plate 22 is provided on the output shaft 2, and the connecting plate 22 is disposed in the first clearance groove 321; a first mounting hole 221 is formed on the connecting plate 22, and a through second mounting hole 322 is formed on the support sub-plate 32, the first mounting hole 221 and the second mounting hole 322 corresponding to each other; the connecting assembly includes a connector 41, which is connected to the inner wall of the first mounting hole 221 through the second mounting hole 322; wherein, the side wall of the connecting plate 22 abuts against the inner side wall of the first clearance groove 321.

[0047] In this embodiment, when the torque tube 3 is installed and fixed on the output shaft 2, the first mounting hole 221 corresponds to the second mounting hole 322. A connector 41 can be used to pass through the second mounting hole 322 and connect to the inner wall of the first mounting hole 221, thus completing the fixation of the support plate 31 on the output shaft 2. The connector 41 can be a connecting bolt, a connecting screw, or a connecting rod. In this embodiment, the connector 41 can be a connecting bolt. The shape of the connecting plate 22 is adapted to the shape of the first clearance groove 321. The connecting plate 22 is located in the first clearance groove 321, and the side wall of the connecting plate 22 abuts against the inner side wall of the first clearance groove 321. When the torque tube 3 rotates, the first clearance groove 321 can limit the rotation direction of the torque tube 3 on the connecting plate 22. At the same time, the first mounting groove 21 also limits the rotation direction of the torque tube 3 on the support plate 31. The two limiting effects work together to effectively reduce the relative rotational slippage between the torque tube 3 and the output shaft 2, and improve the torsional resistance of the bracket.

[0048] In an optional embodiment, a second mounting groove 311 is formed on the side of the support plate 31 away from the cavity 33, and the support sub-plate 32 is located in the second mounting groove 311; the connecting assembly includes a connecting piece 42, which is disposed in the second mounting groove 311, and the side wall of the connecting piece 42 abuts against the inner side wall of the second mounting groove 311; a second clearance groove 422 is provided on one side of the connecting piece 42, and the support sub-plate 32 is located in the second clearance groove 422; a through third mounting hole 421 is provided on the connecting piece 42, which corresponds to the first mounting hole 221 and the second mounting hole 322; the connecting member 41 passes through the third mounting hole 421 and the second mounting hole 322 in sequence and connects to the inner wall of the first mounting hole 221; wherein, the side wall of the support sub-plate 32 abuts against the inner side wall of the third clearance groove.

[0049] In this embodiment, when the torque tube 3 is installed and fixed on the output shaft 2, the first mounting hole 221, the second mounting hole 322 and the third mounting hole 421 correspond to each other. The connector 41 can be used to pass through the third mounting hole 421, the second mounting hole 322 and connect to the inner wall of the first mounting hole 221, thus completing the fixation of the support plate 31 on the output shaft 2. The shape of the connecting piece 42 is adapted to the shape of the second mounting groove 311. The connecting piece 42 is located in the second mounting groove 311 and the side wall of the connecting piece 42 abuts against the inner side wall of the second mounting groove 311. At the same time, the side wall of the support sub-plate 32 abuts against the inner side wall of the third clearance groove. When the torque tube 3 rotates, the first clearance groove 321 can limit the rotation direction of the torque tube 3 on the connecting plate 22. At the same time, the first mounting groove 21 also limits the rotation direction of the torque tube 3 on the support plate 31. Meanwhile, the second mounting groove 311 also limits the rotation direction of the torque tube 3 on the connecting piece 42. At the same time, the third clearance groove also limits the rotation direction of the torque tube 3 on the support sub-plate 32. The four limiting functions work together to greatly reduce the tendency of relative rotational slippage between the torque tube 3 and the output shaft 2, effectively improving the torsional resistance of the bracket.

[0050] In an optional embodiment, a fixing plate 43 is provided at the end of the connecting piece 42 away from the torque tube 3, and a fixing groove 23 is provided on the output shaft 2, in which the fixing plate 43 is disposed; wherein, the fixing plate 43 is arranged perpendicularly to the connecting piece 42, and the fixing plate 43 is used to reduce the tendency of the torque tube 3 and the output shaft 2 to move relative to each other in the axial direction.

[0051] In this embodiment, the torque tube 3 is used to install the main beam. The main beam is relatively long and will exert a tensile force on the torque tube 3 in one axial direction. In this embodiment, by setting the fixing plate 43 in the fixing groove 23, the tendency of the torque tube 3 and the output shaft 2 to move relative to each other in the axial direction is effectively reduced, thereby effectively reducing the deformation of the first mounting hole 221 and the second mounting hole 322 caused by the compression in the axial direction of the torque tube 3.

[0052] It should be noted that in traditional technology, screws are generally used to connect the torque tube 3 and the output shaft 2. Therefore, both the torque tube 3 and the output shaft 2 have threaded holes. Due to the relative rotation or relative axial movement of the torque tube 3 and the output shaft 2, the walls of the threaded holes will be compressed, thereby affecting the connection strength and stability of the torque tube 3 and the output shaft 2.

[0053] In an optional embodiment, the thickness of the support subplate 32 is less than or equal to the depth of the second mounting groove 311, and the thickness of the support subplate 32 is less than or equal to the depth of the third clearance groove.

[0054] In this embodiment, the thickness of the support sub-plate 32 can be equal to the depth of the second mounting groove 311 and less than the depth of the third clearance groove, so that the support sub-plate 32 can be completely located in the third clearance groove, and at the same time, the connecting piece 42 can be completely located in the second mounting groove 311. This enables the second mounting groove 311 to exert an anti-torsion effect on the connecting piece 42, and the third clearance groove to exert an anti-torsion effect on the support sub-plate 32, thereby improving the anti-rotation slippage capability of the torque tube 3 and the output shaft 2.

[0055] In an optional embodiment, along the direction in which the torque tube 3 is mounted on the output shaft 2, the depth of the second mounting groove 311 gradually decreases, and the thickness of the connecting piece 42 gradually decreases.

[0056] In this embodiment, the depth of the second mounting groove 311 gradually decreases, forming a wedge-shaped inclined groove. The connecting piece 42, which also has a wedge-shaped structure, can be aligned and joined by sliding or pushing, reducing the complex alignment process and installation errors. At the same time, when the torque tube 3 and the output shaft 2 move relative to each other along the axial direction, the bottom of the inclined groove of the second mounting groove 311 can convert the horizontal force generated by the connecting piece 42 into vertical pressure, enhancing the shear resistance and making the connection between the two more stable.

[0057] In an optional embodiment, the thickness of the connecting plate 22 is less than the depth of the first mounting groove 21, and the thickness of the connecting plate 22 is less than or equal to the depth of the first clearance groove 321.

[0058] In this embodiment, the thickness of the connecting plate 22 can be less than the depth of the first mounting groove 21 and less than the depth of the first clearance groove 321, so that the support plate 31 can be completely located in the first mounting groove 21, and at the same time, the connecting plate 22 can be completely located in the first clearance groove 321. This enables the first mounting groove 21 to exert an anti-torsion effect on the support plate 31 and the first clearance groove 321 to exert an anti-torsion effect on the connecting plate 22, thereby improving the anti-rotation and anti-slip capability of the torque tube 3 and the output shaft 2.

[0059] In an optional embodiment, along the direction in which the torque tube 3 is mounted on the output shaft 2, the thickness of the support plate 31 gradually decreases, and the depth of the first mounting groove 21 gradually decreases.

[0060] In this embodiment, the depth of the first mounting groove 21 gradually decreases, forming an inclined groove. During the installation of the torque tube 3, the support plate 31 on the torque tube 3 can be directly aligned and joined by sliding or pushing, reducing the complex alignment process and installation errors. On the other hand, compared with a direct parallel surface connection, the contact area between the inclined first mounting groove 21 and the support plate 31 is larger, making the pressure or shear force on the output shaft 2 more evenly distributed, thereby improving the strength and stability of the connection. In addition, since the torque tube 3 and the output shaft 2 will move relative to each other in the axial direction, when the inclined first mounting groove 21 is subjected to the axial force of the support plate 31, part of the horizontal force of the support plate 31 can be converted into vertical pressure, enhancing the shear resistance and making the connection more secure.

[0061] In an optional embodiment, there are multiple support plates 31, and each support plate 31 is arranged at intervals along the circumference of the torque tube 3; the number of first mounting slots 21 is the same as that of support plates 31, and the first mounting slots 21 are arranged in a one-to-one correspondence with the support plates 31.

[0062] In this embodiment, multiple support plates 31 can be evenly spaced along the circumferential interval of the torque tube 3, which effectively improves the connection strength and stability between the torque tube 3 and the output shaft 2, and further improves the anti-rotation slippage capability between the torque tube 3 and the output shaft 2.

[0063] Secondly, embodiments of this application may provide a photovoltaic tracking bracket, which includes: a column, a main beam, and a torque tube and drive mechanism assembly as described in any of the above embodiments; the drive mechanism 1 is disposed on the column, and the torque tube 3 is connected to the main beam.
