[0002] Photovoltaic panels are the core components of photovoltaic power generation systems. They are composed of structures such as tempered glass, solar cells, backplanes, and junction boxes. When sunlight shines on the semiconductor material (such as crystalline silicon) in the photovoltaic panel, the photon energy causes the electrons in the semiconductor material to jump, forming free electron-hole pairs. These free electrons and holes are separated by the electric field of the PN junction, thereby generating electromotive force and current. Based on the photovoltaic effect, the photovoltaic panel converts light energy into electrical energy, which is then used by users through equipment such as inverters. The photovoltaic panel bracket is an important structure used to fix and support the photovoltaic panel.

At this time, the elastic clip (903) is released, and the placed photovoltaic panel components are removed and stored in the storage box; S2: The same operation is performed, and the pressing block (16) is pressed to disengage the limiting piece (15) from the limiting groove (14) and keep it stationary. The adjusting knob (13) is rotated in the opposite direction, and the threaded rod (12) drives the two groups of moving blocks (10) to move closer to each other, so that the four groups of folding rods (8) are retracted, and the two groups of photovoltaic panel frames (9) are driven to move closer to the outer walls of the two sides of the support beam (6). When the two groups of photovoltaic panel frames (9) are close to the outer wall of the support beam (6), the pressing block (16) is released to realize the storage of the photovoltaic panel frames (9); S3: Holding the outer wall of the rotating drum (401), rotating the rotating drum (41) to drive the threaded rod (402) to move, adjusting the length of the rotating drum (41) and the threaded rod (402), and adjusting the tilt angle of the rear connecting block (404) and the front connecting block (405) hinged to the rotating drum (401) and the threaded rod (402), thereby moving the tilting plate (5) whose angle was previously adjusted closer to the horizontal plate (3), thereby achieving the storage of the tilting plate (5); S4: Remove the fixing bolts (201), extract the support column (2) from the column (1), and combine the column (1) and the two sets of photovoltaic panel frames (9) that have been tightened and store them together for easy storage and transportation.
