A spring is provided in the elastic telescopic shaft 7. The second drying box 8 and the first drying box 6 are connected together through the elastic telescopic shaft 7, so that the second drying box 8 and the first drying box 6 can move synchronously.
[0037] After the solar panel 1 has been through rain, the device dehumidifies and dries the connection gap in time. The solar panel 1 is installed by clamping the upper and lower ends on the frame 2, and the first drying box 6 is driven by the driving mechanism to move back and forth in the first groove 3. During the movement of the first drying box 6, the heating plate 16 will be energized to generate heat to heat the air within the range of the first drying box 6, and the hot air will flow toward the connection between the solar panel 1 and the frame 2 through the air vent 15.

The traction rope 17 will be pulled continuously, and the angle of each heating plate 16 will change during the pulling process. The heating plate 16 swinging up and down can stir the hot air in the first drying box 6, accelerate the gas flow and have an auxiliary effect on drying.
[0040] Both ends of the first groove 3 are closed by a partition 10, and the partition 10 is detachably mounted on the frame 2 by screws. The user can completely disassemble the first drying box 6 and the second drying box 8 by pulling them out from one end. The first drying box 6 and the second drying box 8 are connected by an elastic telescopic shaft 7, and the retractable elastic telescopic shaft 7 can adapt to photovoltaic modules of different sizes.
