The solar energy of the photovoltaic panel 2 is converted into electrical energy by the inverter 3 through the photovoltaic cell 5 and stored. The photovoltaic cell 5 is cooled by the radiator 6 to ensure that the temperature of the photovoltaic cell 5 is not too high and increase unnecessary risks, thereby ensuring the normal operation of the photovoltaic cell 5.

At the same time, the piston frame 1502 limits the piston plate 1507 to ensure that the piston frame 1502 limits the reciprocating ring 1506, so that the reciprocating screw 1505 can move up and down with the reciprocating ring 1506, forming power to push the hot steam, and cooperate with the contraction nozzle 11 to increase the flow rate of the airflow, thereby realizing the drive of the transmission mechanism 12.
