A motor is arranged on one of the first fixed plates 33 to drive the first screw rod 34 to rotate, so as to drive the sliding plate 31 to slide; and in order to ensure that the position of the sliding plate 31 remains stable after adjustment (that is, the inclination angle of the mounting plate 2 remains stable after adjustment), the first screw rod 34 needs to have self-locking properties, that is, the thread lead angle of the first screw rod 34 is smaller than the equivalent friction angle.

[0032] Of course, the method of driving the sliding plate 31 to slide includes but is not limited to the first screw rod 34 and other structures in this embodiment. In some embodiments, the sliding plate 31 can also be directly slid by setting a cylinder, a telescopic rod, an electric push rod and other linear driving components at the upper end of the support frame 1.

[0033] A shielding plate 4 is provided on both sides of the support frame 1, and the two shielding plates 4 can be turned upward synchronously to shield the top of the photovoltaic panel, so as to facilitate shielding and protecting the photovoltaic panel in rainy and snowy weather;

[0037] Furthermore, in order to ensure that the position of the shielding plate 4 remains stable after being flipped and adjusted, the second screw rod 54 needs to have self-locking properties, that is, the thread lead angles of the first external thread 541 and the second external thread 542 are both smaller than the equivalent friction angle.

[0038] Of course, the method of driving the two connecting plates 53 to slide synchronously in opposite directions includes but is not limited to the second screw rod 54 and other structures in this embodiment. In some embodiments, two cylinders can be set on the support frame 1 to drive the two connecting plates 53 to slide synchronously in opposite directions respectively.

[0039] Working principle:

[0040] The angle of the mounting plate 2 is adjusted by setting an angle adjustment component 3 between the support frame 1 and the mounting plate 2, thereby adjusting the tilt angle of the photovoltaic panel to adapt to the angle of sunlight in different time periods. By setting a mounting groove 21 on the mounting plate 2 to cooperate with the photovoltaic panel, and setting bolts to lock the photovoltaic panel, the portability of disassembly and installation is guaranteed. By setting a shielding plate 4 on both sides of the support frame 1, and setting a driving component 5 so that the two shielding plates 4 can be synchronously reversed, and the two shielding plates 4 can be spliced ​​directly above the photovoltaic panel, the photovoltaic panel can be protected and shielded in rainy and snowy weather.
