Simply put, a photovoltaic module is a facility composed of several solar cells. Currently, a large number of photovoltaic modules are used in photovoltaic power generation. During transportation, a large number of photovoltaic modules are stacked and stored. Affected by the shock of the transportation environment, the frames of the photovoltaic modules are extremely prone to collision deformation, affecting the internal sealing of the solar cells. Therefore, a protection device is needed to protect the transportation of photovoltaic modules.

Before transporting a large number of photovoltaic modules, installing the protection angles has already consumed a large amount of time and manpower, not to mention that when unloading the photovoltaic modules, the protection angles need to be disassembled again.

After the adjustment is completed, move the L-shaped rod 22 around the pin The shaft 26 rotates forward, and the L-shaped rod 22 drives the front protective plate 17 to flip forward through the telescopic rod 20. Then the bottom of the photovoltaic component 2 is inserted into the lower groove 7 of the movable seat 4, and the photovoltaic component 2 is pushed backward. The ball 8 supports the photovoltaic component 2 to slide in the lower groove 7 until the rear side wall of the photovoltaic component 2 contacts the inner wall of the side plate 9. At this time, the rear corner of the top of the photovoltaic component 2 is inserted into the upper groove 18. According to the above steps, several photovoltaic components 2 are loaded in sequence, and then the L-shaped rod 22 is moved to rotate around the pin shaft 26.
