Under the continuous rotation of the transmission shaft 805, the guide rod 807 and the guide groove 808 can drive the sponge frame 810 on the adapter plate 809 to automatically and stably reciprocate up and down on the condenser 4. Combined with the electric heating wire 812 in the heat pipe 811, the frost on the condenser 4 can be melted efficiently and stably, ensuring that the condenser 4 can work normally, thereby ensuring that the heat pump system can maintain efficient operation. Moreover, under the heat conduction action of the heat pipe 811, the heating efficiency of the condenser 4 can be further improved, saving the energy consumption of the heat pump air conditioner.

[0027] The sponge frame 810 can drive the first flexible brush 813 and the second flexible brush 815 on the fixed rod 814 to move up and down simultaneously during the up and down reciprocating motion. The first flexible brush 813 can automatically clean the axial flow fan blades 7 during the motion. At the same time, the second flexible brush 815 can also be used to automatically clean the second filter plate 13 on the front cover plate 12, which helps to ensure sufficient air circulation, thereby improving the efficiency of the heat pump, avoiding dust and impurities from adhering to and accumulating on the axial flow fan blades 7 and the second filter plate 13, affecting the air circulation inside the heat pump air conditioner, and in the process of thawing and defrosting the condenser 4, the thawing and defrosting The water produced by frost will automatically flow into the water tank 816. At this time, the electric heating tube 818 can be used to heat the water produced by the initial thawing and defrosting, and the water inlet pipe 9 can also be used to transport water to the water tank 816. After the water in the water tank 816 is heated, the suction pipe 821 on the small water pump 820 is used to suck the hot water in the water tank 816, and the heated water is transported to the sponge frame 810 through the rubber hoses 822 on both sides. The reciprocating motion of the sponge frame 810 and the hot water inside it can further improve the thawing and defrosting efficiency of the condenser 4, and at the same time, the hot water can be used to further improve the heating efficiency of the condenser 4. When the heat pump air conditioner is working in summer, it is not necessary to heat the water in the water tank 816, and it is also not necessary to turn on the electric heating wire 812 and the electric heating tube 818. Through the same operation, after the unheated water is transported to the sponge frame 810 through the rubber hose 822, the water is coated on the condenser 4 by the reciprocating motion of the sponge frame 810, and the evaporation of water is used to absorb heat, which helps the condenser 4 to dissipate heat efficiently, improves the cooling efficiency of the condenser 4, and can also save energy consumption when the heat pump air conditioner is working in summer. When the solar photovoltaic panel 1710 is finished using, it is only necessary to drive the servo motor 1702 to drive the wire roller 1703 to reel in the traction rope 1704. Under the reeling action of the traction rope 1704, the mounting plate 1705 and the solar photovoltaic panel 1710 can be pulled to rotate in the opposite direction to fold the mounting plate 1705 and the solar photovoltaic panel 1710. After the mounting plate 1705 and the solar photovoltaic panel 1710 are folded, the wire roller 1703 continues to reel in the mounting plate 1705, so that the mounting plate 1705 can be pulled downward to drive the telescopic sleeve rod 1710 to rotate in the opposite direction. 1 moves downward and contracts until the telescopic sleeve rod 1711, the mounting plate 1705 and the solar photovoltaic panel 1710 move downward into the storage frame 15, and cooperates with the rubber sheet 16 to conveniently and stably store and protect the solar photovoltaic panel 1710. In addition, when the solar photovoltaic panel 1710 is in the folded state and moves downward, the flexible cleaning plate 1719 in the storage frame 15 can automatically clean the solar photovoltaic panel 1710, thereby ensuring the stability of the solar photovoltaic panel 1710 in the repeated use state and prolonging the service life of the solar photovoltaic panel 1710. When the solar photovoltaic panel 1710 needs to be inspected, maintained or replaced, the solar photovoltaic panel 1710 only needs to be unfolded, and the staff only needs to push the blocking blocks 1709 on both sides to move into the positioning blocks 1707. Then the staff can move the positioning blocks 1707 on the solar photovoltaic panel 1710 out of the positioning grooves 1706 on the mounting plate 1705 to complete the disassembly of the solar photovoltaic panel 1710. After the solar photovoltaic panel 1710 is inspected, maintained or replaced, the staff can fit the solar photovoltaic panel 1710 to the mounting plate 1705 and insert the positioning blocks 1707 on the solar photovoltaic panel 1710 into the mounting plate 1705. The positioning block 1707 is inserted into the positioning groove 1706 on the plate 1705, and during the insertion process of the positioning block 1707, under the guidance of the inclined surface at the end of the block 1709, the positioning groove 1706 can push the blocks 1709 on both sides to automatically move into the positioning block 1707 until the positioning block 1707 drives the block 1709 to pass through the positioning groove 1706. At this time, under the elastic action of the reset spring 1708, the block 1709 can be driven to move automatically outward, and the positioning block 1707 and the positioning groove 1706 can be used to engage and install the solar photovoltaic panel 1710 on the mounting plate 1705, thereby ensuring the stability of the subsequent working state of the solar photovoltaic panel 1710.
