The working principle of the starting structure 19 and the purging structure 20 is as follows:
in the first case (cleaning mode), when dust on the PV panel 16 needs to be cleaned, referring to fig. 18, a state diagram of use of the starting structure 19 and the purging structure 20 is shown, and it can be seen from the figure that only the cover plate 14 needs to be moved downwards (c 2 direction), the cover plate 14 can drive the support arm 1901 and the pushing unit 1902 to move towards the gap between the flap 2004 and the button until the pushing units 1902 on two sides of the support arm 1901 are respectively contacted with the flap 2004 and the button; the pushing unit 1902 continues to move, so that the turning plate 2004 turns over along the d direction, and the turning plate 2004 drives the plugging disc 2002 to turn over; at this time, a gap is formed between the sealing disk 2002 and the gas tank 2001 (see fig. 17), and at the same time, the push unit 1902 on the other side pushes the button to temporarily start the blower 2006, the blower 2006 pumps outside air into the gas tank 2001, and the air is ejected from the nozzle 2005 and purges the PV cell plate 16; then, when the pushing units 1902 on both sides of the support arm 1901 completely pass through the turning plate 2004 and the button, the turning plate 2004 and the button are reset under the action of the second torsion spring and the third torsion spring, so that the spray head 2005 stops spraying the PV cell panel 16. And (3) injection: when the pushing unit 1902 moves along the direction c2, the pushing unit 1902 cannot be turned over due to the blocking body 1902.2 blocking the pushing unit 1902.
In the second case, after the cleaning of the PV panel 16 is completed, referring to fig. 14, the pushing unit 1902 is lifted (along the direction c 1) indirectly by the cover 14, and since the second torsion spring and the third torsion spring are both larger than the elastic force of the first torsion spring, when the pushing units 1902 on both sides of the support arm 1901 pass through the turning plate 2004 and the button, the pushing units 1902 on both sides turn over along the directions f1 and f2, respectively, and the turning plate 2004 and the button do not move until the pushing units 1902 completely pass through the gap between the turning plate 2004 and the button.
According to the invention, the storage box body and the folding photovoltaic panel assembly are combined, so that the PV cell panel 16 can be selectively stored in the storage box body or the PV cell panel 16 can be selectively unfolded to collect solar energy according to different requirements; the present invention can be miniaturized for portable charging devices such as mobile phones, and can also be used as large-scale power generation devices. On the other hand, the invention can timely remove dust on the PV cell panel 16 by combining the cleaning component; another feature of the present invention is that the cleaning assembly automatically purges the PV cell panel 16 during the process of housing the folded photovoltaic panel assembly in the housing box and stops after the automatic purge.
