When unloading, the plurality of stacked protective frames 1 can be erected to contact the ground with the pulley 26, at this time, the plurality of protective frames 1 can be pushed to slide and move, at this time, the limiting shaft one 11 realizes the penetration limiting of the long handle bolt 24, and the limiting shaft one 11 also serves as the limiting center shaft when the baffle 12 rotates, and the limiting shaft one 11 also satisfies the positioning function when the plurality of protective frames 1 are stacked, so the limiting shaft one 11 is multi-purpose.

[0050] The protective frame 1 not only realizes the protection of the photovoltaic module 2, but also realizes the anti-deviation limiting function when a plurality of photovoltaic modules 2 are stacked, and realizes the sliding transfer function after the plurality of stacked photovoltaic modules 2 are erected, that is, the protective frame 1 is multi-purpose and has rich functions.

The bottom plate of the protective frame 1 is fixed with a rubber pad 3, which is clamped between the photovoltaic panel assembly 2 and the bottom plate of the protective frame 1, and provides buffer protection for the photovoltaic panel assembly 2. It should be noted that the thickness of the photovoltaic panel assembly 2 should be less than the distance from the top surface of the protective frame 1 to the bottom plate of the protective frame 1, and the distance is equal to the thickness of the baffle 12.

[0053] II. The use of the rubber cover: In order to better protect the photovoltaic panel assembly 2, the tensioning strip 8 is deformed to drive the elastic traction piece 9 to move away from the side wall of the edge groove 4, and then the rubber cover 5 is pulled out of the edge groove 4. The traction rubber cover 5 is covered on the protective frame 1, ensuring that the rubber cover 5 is pulled tight in a tense state. The surface of the rubber cover 5 is provided with a plurality of reserved openings. When the rubber cover 5 is laid on the protective frame 1 and covers the photovoltaic panel assembly 2, the top end of the limiting shaft one 11 should be inserted into the reserved opening.

The rubber cover 5 in the edge groove 4 is limited by the tensioning strip 8 and the plurality of elastic traction pieces 9, and will not fall out.

[0054] III. The use of the baffle: The baffle 12 is pushed into the reserved groove 10 on the top surface of the protective frame 1 in the idle state.

At this time, the baffle 12 serves as part of the side plate of the protective frame 1, and together protects the photovoltaic panel assembly 2. After the photovoltaic panel assembly 2 is placed in the groove body of the protective frame 1, the baffle 12 is rotated by ninety degrees with the limiting shaft one 11 as the center axis into the inner ring opening of the protective frame 1, and the baffle 12 on the other side is also adjusted out according to this method. At this time, the plug plate 18 and the positioning groove 19 provided on the surface of the baffle 12 correspond, the rubber belt 21 returns to pull the plug plate 18 into the positioning groove 19, realizing the anti-swing limiting of the baffle 12, and the baffle 12 is blocked above the photovoltaic panel assembly 2, avoiding the photovoltaic panel assembly 2 from being jolted in the protective frame 1. In order to further reinforce the protection of the two groups of baffles 12 to the photovoltaic panel assembly 2, a threaded nut can be selected to be sleeved on the stud composed of the limiting shaft one 11 at the end of the two baffles 12 close to each other, so that the two baffles 12 are connected together to jointly bear the upward impact force of the photovoltaic panel assembly 2. When the baffle 12 is stored, it is pushed back into the reserved groove 10 to return to the idle state, and continues to serve as part of the protective frame 1 to protect the photovoltaic panel assembly 2.

[0055] IV. The stacking of a plurality of protective frames: The bottom surface of the protective frame 1 is provided with a stacking groove 27 corresponding to the limiting shaft one 11. When two protective frames 1 are stacked, the top of the limiting shaft one 11 on the lower protective frame 1 is inserted into the stacking groove 27 at the bottom of the upper protective frame 1, realizing the neat alignment and stacking of the two adjacent protective frames 1. The top surface of the stacking groove 27 is fixed with a rubber sheet 28, which is clamped between the limiting shaft one 11 and the stacking groove 27, and plays a certain damping role.
