[0044] The two ends of the damper 4 are slidably arranged on the sliding rails on the main beam assembly and the stand column assembly through the connecting structure 3, when adjusting the inclination of the main beam, the main beam assembly rotates an angle, and the damper 4 is extended or retracted at the same time, the connecting structure 3 slides along the sliding rail, and after the adjustment of the inclination is completed, the limiting structure 311 fixes the position of the connecting structure 3.

[0045] The connecting structure 3 and the sliding rail cooperate to limit the movement direction of the damper 4, so that the damper 4 only moves in the length direction, the displacement and deformation of the damper 4 outside the set movement plane are limited, and the shaking is reduced.The overall damping ratio of the structure is increased, the probability of wind-induced damage of the structure under large inclination is reduced, and the friction when the main beam rotates is reduced.

[0046] In a possible implementation, with reference to Figure 1 And Figure 2 The photovoltaic support of the utility model comprises a main beam assembly, a stand column assembly, a damper 4 and a spherical bearing 6.The main beam assembly comprises a main beam 11, a main beam connecting piece 12 and a purlin 13.The purlin 13 and the main beam connecting piece 12 are fixedly connected with the main beam 11 respectively.A first sliding rail 14 is arranged on the main beam connecting piece 12, and the purlin 13 is used for fixing a photovoltaic panel 5. Optionally, a fixing block 24 is arranged on the main beam 11, the two ends of the purlin 13 are connected with the fixing block 24 respectively, and the two ends of the main beam connecting piece 12 are connected with the fixing block 24 respectively, so as to reduce the strength loss of the main beam 11 caused by welding or punching.

[0047] The column assembly comprises a column 21 and a column connecting piece 22. The column connecting piece 22 is fixedly connected with the column 21, and the second sliding rail 23 is arranged on the column connecting piece 22. Optionally, the fixed block 24 is arranged on the column 21, and the two ends of the column connecting piece 22 are connected with the fixed block 24 respectively. The column connecting piece 22 and the column 21 are connected through the fixed block 24, so as to reduce the strength loss of the column 21 caused by welding or punching. Referring to Figure 3 , the first sliding rail 14 and the second sliding rail 23 are the same in structure, and are both I-shaped sliding rails.

[0048] Further, the main beam 11 and the column 21 are connected through the spherical bearing 6, so that the main beam 11 can rotate relative to the column 21 to adjust the inclination angle.

[0049] Further, the damper 4 is arranged on the left and right sides of the column 21. The photovoltaic support further comprises a connecting structure 3. The two ends of the damper 4 are connected with the first sliding rail 14 and the second sliding rail 23 through the connecting structure 3 respectively. In this way, when the main beam 11 rotates, the damper 4 extends and retracts at the same time, and the connecting structure 3 slides on the first sliding rail 14 and the second sliding rail 23. However, the specific structure of the first sliding rail 14 and the second sliding rail 23 is not limited in the present application, as long as it can limit the movement direction of the damper 4, and falls within the protection scope of the present application.

[0050] Further, referring to Figure 3 and Figure 4 , the connecting structure 3 comprises a sliding block part 31 and a connecting part 32. The sliding block part 31 is provided with a telescopic limiting structure 311, and the connecting part 32 is provided with a connecting hole 321. The end of the damper 4 is rotatably arranged in the connecting hole 321. The first sliding rail 14 and the second sliding rail 23 are respectively provided with a limiting hole 15 corresponding to the limiting structure 311. When the inclination angle of the main beam 11 is adjusted, the limiting structure 311 is embedded in the limiting hole 15 to fix the position of the connecting structure 3. It should be noted that the sliding block part 31 and the connecting part 32 can be fixedly connected, detachably connected, or integrally formed, which can be set by the person skilled in the art according to actual needs.

[0051] Further, the connecting hole 321 is spherical, the end of the damper 4 is provided with a spherical part matched with the connecting hole 321, and one side of the connecting hole 321 is provided with an opening, so that the spherical part can be embedded into the connecting hole 321 through the opening, and the spherical end of the damper 4 can rotate freely in the connecting hole 321. However, it should be noted that the shape of the connecting hole 321 is not limited to spherical, and the connecting hole 321 can also be circular or square, etc., as long as the damper 4 and the connecting hole 321 can be rotatably connected, such as hinged, etc., and the specific shape of the connecting hole 321 and the connection mode of the damper 4 and the connecting hole 321 are not limited by the utility model, and all fall within the protection scope of the utility model.

[0052] Further, the photovoltaic support further comprises a driving device and a vibration sensor (not shown in the figure), the vibration sensor is arranged on the connecting structure 3, and the driving device and the limiting structure 311 are in transmission connection, so that the driving device drives the limiting structure 311 to perform the telescopic movement.

[0053] When the inclination angle of the photovoltaic structure changes, the limiting structure 311 will be retracted into the connecting structure 3 after the vibration sensor senses a certain vibration value, at this time, the connecting structure 3 can slide on the main beam connecting piece 12 and the column connecting piece 22 and drive the damper 4 to perform the telescopic movement. When the inclination angle of the photovoltaic structure stops changing, the vibration sensed by the vibration sensor decreases, so that the limiting structure 311 is extended, the limiting structure 311 is embedded into the limiting hole 15 on the slide rail, so that the damper 4 is limited at the position and does not produce the movement.

[0054] However, it should be noted that the utility model does not limit the telescopic limiting structure, as long as it can be telescopic according to the requirement, and all fall within the protection scope of the utility model.

[0055] Referring to Figure 1 and Figure 2 When the inclination angle of the main beam 11 is 0°, the main beam 11 is parallel to the horizontal plane, and the main beam 11 is located on the center line of the two dampers 4. It should be noted that when the connecting structure 3 changes the displacement with the change of the inclination angle, the included angle α formed by the damper 4 and the main beam connecting piece 12 is always less than 90°, the inclination angle change range of the photovoltaic support is 0° to 60°, and the telescopic damping effect of the damper 4 can be maintained within the angle, and the shaking is prevented.

[0056] In addition, it also needs to be explained that, although the above embodiment is described by setting the first sliding rail 14 on the main beam connector 12, the skilled in the art can also set the position of the first sliding rail 14 according to actual needs, which can also be set on the purlin 13 or directly on the main beam 11. Similarly, the second sliding rail 23 can also be directly set on the stand column 21. The utility model does not make any limit to the setting position of the sliding rail, and the skilled in the art can set according to actual needs, and all fall within the protection scope of the utility model.

[0057] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but the skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. The skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the utility model, and the technical scheme after the changes or replacements will fall within the protection scope of the utility model.
