[0051] The cooperation of the threaded rod 3 and the slider 11 facilitates the adjustment of the clamping plate 805, and ensures that the rotating parts 8 on both sides of the center line of the fixed frame 1 can simultaneously tighten the vertical beam 12 in the tracking bracket, preventing the photovoltaic panel tracking bracket from overturning when the tracking bracket adjusts the angle of the photovoltaic panel, thereby ensuring the safety of the photovoltaic panel.

[0059] The setting of the limiting member 5 can limit the pulling member 6 in the groove 803 to ensure the normal operation of the pulling member 6.

[0060] In this embodiment, if Figure 7 As shown, a strip hole 1001 is opened at the bottom of the base plate 10, and the adjusting member 7 includes a lead screw 701 and a moving block 702. The two ends of the lead screw 701 are rotatably installed at the two ends of the strip hole 1001 respectively, and the moving block 702 is slidably set in the strip hole 1001, and the moving block 702 is threadedly matched with the lead screw 701. The setting of the adjusting member 7 is convenient for the staff to install the pulling member 6, thereby improving the installation efficiency of the device.

[0061] Rotating the lead screw 701 drives the moving block 702 to move, and the movement of the moving block 702 can drive the pulling member 6 to move. The movement of the pulling member 6 can ensure that the vertical beam 12 on the tracking bracket is tightened to prevent the tracking bracket from overturning during the rotation of the photovoltaic panel, thereby ensuring the safety of the tracking bracket and the photovoltaic panel.

[0062] In this embodiment, if Figure 7 As shown, side plates 1002 are installed on both sides of the bottom plate 10 , and ground anchors 9 identical to those on the side ears 2 are installed on the side plates 1002 .

[0063] The ground anchor nails 9 on the side plate 1002 are used to fix the bottom plate 10 on the ground, ensuring that the bottom plate 10 is always in a stable state during the working process, thereby greatly ensuring the safety of the tracking bracket.

[0064] In order to provide all-round support for the vertical beam 12, in this embodiment, Figure 7 As shown, the pulling member 6 includes a pulling rod 603, a limiting column 604, a support block 606, a guide rod 601, a fixed plate 602 and a first spring 607. The fixed plate 602 is fixedly installed on the top of the moving block 702, and a mounting hole 605 is opened on the fixed plate 602. Both ends of the guide rod 601 are fixedly installed on the two side walls of the mounting hole 605. The support block 606 is slidably set in the mounting hole 605, and the support block 606 is set on the guide rod 601.

[0065] In order to ensure that the pulling rod can play the purpose of pulling the vertical beam 12, the first spring 607 is sleeved on the guide rod 601, and the two ends of the first spring 607 are respectively installed on the support block 606 and the side wall of the mounting hole 605. The setting of the first spring 607 can play the purpose of buffering. When the vertical beam 12 is tilted, the first spring 607 will be stretched or compressed, thereby playing the purpose of buffering, preventing the photovoltaic panel from falling from the tracking bracket, and greatly ensuring the safety of the photovoltaic panel. The pulling rod 603 is symmetrically arranged at both ends of the support block 606 and the limit column 604, one end of the rotating rod 801 is rotatably installed on the support block 606, and the other end of the rotating rod 801 is fixedly installed on the fixed column, the fixed column cooperates with the groove 803, and the limit column 604 cooperates with the groove 803.

[0066] The pulling member 6 is used to pull the vertical beam 12 of the tracking bracket to ensure the safety of the tracking bracket during the process of adjusting the angle of the photovoltaic panel.

[0067] In order to ensure the normal operation of the pulling member and facilitate the installation of the device, in this embodiment, Figure 3 , Figure 5 , Figure 6As shown, the limiting member 5 includes a mounting plate 501, a limiting plate 506, a sliding rod 502, a top plate 503, a sliding plate 504 and a second spring 505. The mounting plate 501 is fixedly mounted on the clamping plate 805, the sliding rod 502 is slidably mounted on the mounting plate 501, the top plate 503 is fixedly mounted on the top of the sliding rod 502, the sliding plate 504 is symmetrically arranged at both ends of the top plate 503, and sliding grooves are opened on both sides of the mounting plate 501, the sliding grooves are matched with the sliding plate 504, and a mounting groove 802 is opened on the right side wall of the groove 803. The limiting plate 506 is rotatably mounted Installed in the mounting groove 802, a fixing rod 507 is installed at the bottom of the sliding rod 502, an avoidance groove 509 is opened on the limit plate 506, and fixing holes 508 are opened on the two side walls of the avoidance groove 509. The fixing rod 507 is slidably set in the fixing hole 508, and a limiting block 5010 is also installed on the sliding rod 502. The limiting block 5010 cooperates with the mounting plate 501. The second spring 505 is sleeved on the sliding rod 502, and the second spring 505 is located between the top plate 503 and the mounting plate 501. The second spring 505 is used to provide power for the sliding rod 502 to reset.

[0068] Pushing the limit column 604 upward from the bottom of the groove 803 will drive the limit plate 506 to rotate around the connection between the limit plate 506 and the mounting groove 802. The rotation of the limit plate 506 will drive the sliding rod 502 to move downward. The downward movement of the sliding rod 502 will compress the second spring 505. When the limit column 604 is located in the groove 803, the limit plate 506 is reset under the action of the second spring 505. The reset of the limit plate 506 blocks the bottom of the groove 803 to prevent the limit column 604 from falling off the groove 803. When the limit plate 506 rotates to be perpendicular to the groove 803, the limit block 5010 cooperates with the mounting plate 501 to limit the movement of the sliding rod 502, thereby preventing the sliding rod 502 from moving excessively, thereby affecting the effect of the limit plate 506 on blocking the groove 803.

[0069] The limit member 5 is used to limit the movement of the limit column 604, ensuring that the limit column 604 is always in the groove 803, ensuring the normal operation of the pulling member 6, and the setting of the limit plate 506 is used to limit the downward movement of the limit column 604 to prevent the limit column 604 from falling off from the groove 803 during operation.
