[0022] A driving motor 13 is also provided on the fixed plate 6, and the output shaft of the driving motor 13 extends to the other side of the fixed plate 6 and is sleeved with a gear. A tooth plate 9 is also provided at one end of the L-shaped plate 10, and the tooth plate 9 is meshed with the gear. The extension plate 11 is adapted to the opening 5, and the width of the extension plate 11 is the same as the diameter of the rotating disk 2. A clamping block is also provided on the rotating disk 2, and the clamping block is adapted to the photovoltaic bracket, and a servo motor for driving the rotating disk 2 to rotate is provided inside the base 1.
[0023] It is worth noting that the static load test is to test the performance of the photovoltaic bracket under static load. During the test, the load is gradually added to the photovoltaic bracket to make it evenly distributed, and the load is maintained for one hour. Check whether there is intermittent circuit breaking during the test, whether there are serious appearance defects, and conduct maximum output power test and insulation resistance test under standard test conditions.
[0024] The dynamic load test is to simulate the dynamic loads that the bracket may be subjected to in actual use, such as loads generated by natural factors such as wind and snow. In the test, dynamic mechanical loads are applied to the photovoltaic bracket for multiple cycles to monitor the circuit continuity of the components.
[0025] Working principle: When the device is in use, the photovoltaic bracket is installed on the rotating disk 2, and then the counterweight is placed between the intervals of the partition 17 on the box body 16, and the telescopic rod 19 is moved up and down, so that the counterweight is slowly unloaded to ensure that only one counterweight is lowered at a time. The counterweight is slowly moved to the surface of the photovoltaic bracket through the first inclined plate 20 and the second inclined plate 21, and the photovoltaic bracket is driven to rotate by the rotating disk 2, so that the counterweight is evenly distributed in the mounting groove on the surface of the photovoltaic bracket, and then a static load test is carried out. The tooth plate 9 is driven up and down by the driving motor 13, and then the L-shaped plate 10 and the extension plate 11 are driven to move, and then the fan 12 is driven to move to the bottom of the cross plate 4, so that the fan 12 is aligned with the photovoltaic bracket, and then a dynamic load test simulation is carried out. At the same time, it is supported by the connecting block 8 and the movable rod 7 through the spring 15. At the same time, when the driving motor 13 drives the tooth plate 9 to move downward, the spring 15 contracts to maintain the stability of the fan 12.
