The other end of the bidirectional screw 10 is connected to the power input end of the generator 14. The power output end of the generator 14 is connected to the converter 2 through a circuit. The converter 2 includes a module for converting light energy into electrical energy.

[0017] As a further preferred embodiment, the heating device 3 further includes a water device 16 , a second branch water pipe 17 is connected to the heating tank 15 , and the second branch water pipe 17 is connected to the water device 16 .

[0018] As a further preferred embodiment, the water inlet end of the heating tank 15 is connected to a water supply pipe 18 , and the water supply pipe 18 is connected to a water source via a water pump.

[0019] As a further preference, the inner side surfaces of the first purification plate 11 and the second purification plate 12 are slidingly connected to the photovoltaic surface of the photovoltaic power generation panel 9 through a slide rail 19, and a threaded transmission seat 20 is fixed on the inner side surfaces of the first purification plate 11 and the second purification plate 12, and the two threaded transmission seats 20 are respectively transmission-connected to the bidirectional threads of the bidirectional screw 10.

[0020] As a further preference, the first purification plate 11 and the second purification plate 12 are provided with seepage holes 23 , which are in contact with the photovoltaic surface of the photovoltaic power generation panel 9 , and the liquid seeps onto the photovoltaic surface of the photovoltaic power generation panel 9 through the seepage holes 23 .

[0021] As a further preference, the photovoltaic frame 8 is arranged at an angle, and a spring seat 24 is installed on the inclined surface of the photovoltaic frame 8 in a vertical manner. The photovoltaic power generation panel 9 is connected to the spring seat 24, and a pressure sensor 25 is fixed on the photovoltaic power generation panel 9. A controller unit 26 is installed on the photovoltaic frame 8, and the controller unit 26 is electrically connected to the pressure sensor 25. A solenoid valve 27 is installed on the first steam exhaust pipe 7, and the controller unit 26 is also electrically connected to the solenoid valve 27. A third steam exhaust pipe 28 is also connected to the air outlet of the steam generator 4, and a pressure valve 29 is installed on the third steam exhaust pipe 28.

[0022] Working principle and effect: Under the action of the water pump, the water supply pipe 18 injects cold water into the heating tank 15, the photovoltaic panel 9 absorbs solar energy, and uses the converter 2 to convert light energy into electrical energy and store it in the storage module, and the electrical energy is used to heat the water in the heating tank 15. A part of the hot water passes through the second branch water pipe 17 to serve the water device 16. The water device 16 here can be based on user needs, such as bathing environment, heating environment, etc. A portion of the hot water enters the steam generator 4 through the first branch water pipe 5. As the water temperature gets higher and higher, the water pressure also gets higher and higher. The high water pressure generates steam in the steam generator 4. As the steam pressure gets higher, the solenoid valve 27 is opened and the steam enters the first steam discharge pipe 7, and then enters the steam turbine 6. The steam turbine 6 uses steam as a separate component. According to the structure of the steam turbine 6, its power output shaft 13 will rotate, and its power output shaft 13 will rotate with the bidirectional screw 10 in the present invention. The bidirectional screw 10 drives the two threaded transmission seats 20 to move toward or in reverse. The two threaded transmission seats 20 drive the first purification plate 11 and the second purification plate 12 to move toward or in reverse. During actual assembly, a limit switch will be set on the stroke of the first purification plate 11 and the second purification plate 12 to control the stroke of the first purification plate 11 and the second purification plate 12, such as the first purification plate 11 and the second purification plate 12. When the two purifiers 2 move toward each other and are about to collide with each other, the limit switch sends a command to the electronic control system of the photovoltaic device, which controls the solenoid valve 27 to close. The first steam exhaust pipe 7 stops supplying gas to the steam turbine 6, and the steam turbine 6 stops working. The first and second purifiers 11, 12 stop moving toward each other. The first and second purifiers 11, 12 are moved along the photovoltaic surface of the photovoltaic panel 9 to automatically clear the snow attached to the photovoltaic surface. The power of the first and second purifiers 11, 12 comes from the rotation of the bidirectional screw 10, and the power of the rotation of the bidirectional screw 10 comes from the action of the steam turbine 6. The power of the steam turbine 6 when it is in action comes from the steam produced by the steam generator 4. The steam in the steam generator 4 is generated by heating the water in the heating tank 15. The heating principle of the heating tank 15 comes from the conversion of solar energy. Therefore, in the present invention, photovoltaic heating is expanded to multiple power sources, making the conversion and utilization of light energy more extensive.

[0023] In addition, the second steam exhaust pipe 21 on the steam generator 4 will also discharge part of the steam to the second purification plate 12. After being collected by the second purification plate 12, this part of the steam will be discharged to the first purification plate 11 through the flexible pipe 22. As the first purification plate 11 and the second purification plate 12 move, the steam will act on the photovoltaic surface of the photovoltaic panel 9, so that the steam can be used again. Since the steam has a certain temperature, when they are added to the first purification plate 11 and the second purification plate 12, the first purification plate 11 and the second purification plate 12 are heated. The movement of the first purification plate 11 and the second purification plate 12 will effectively destroy the snow or ice attached to the photovoltaic surface. Another part of the steam is discharged outward through the third steam exhaust pipe 28 according to user or production needs or applied to a third-party steam environment.

[0024] In summary, the present invention extends the photovoltaic thermal effect not only to the conventional heating of water in the heating tank 15, but also to the steam generator 4 and the steam turbine 6, allowing for application in a third environment. In particular, in the combined application of the steam generator 4 and the steam turbine 6, a portion of the generated steam is reapplied to the photovoltaic panels 9, benefiting the photovoltaic panels 9. In addition, when the bidirectional screw 10 rotates, the other end is used to drive the generator 14, which converts the generated mechanical rotational force into electrical energy. The electrical energy is then stored in the battery through existing photovoltaic principles, thereby increasing the conversion of electrical energy and further achieving energy conservation.

[0025] The present invention also discloses a heating treatment method, which is applicable to the above-mentioned optical heating device, comprising the following steps: Step S01: Connect the input end of the converter 2 to the photovoltaic panel 9 circuit to convert light energy into electrical energy; Step S02: connecting the output end of the converter 2 to the circuit of the heating device 3 so that part of the converted electric energy is converted into energy for electrical heating of the heating device 3; Step S03: The heating device 3 separates the hot water into two parts. One part of the hot water is transported to the steam generator 4 through the first branch water pipe 5 to be converted into steam to serve the energy of the steam turbine 6; the other part of the hot water is transported to the water device 16 through the second branch water pipe 17; Step S04: Connect the exhaust port of the steam turbine 6 to the flexible pipe 22, and use the flexible pipe 22 to apply the exhausted steam to the first purification plate 11, the second purification plate 12 and the generator 14. This not only causes the first purification plate 11 and the second purification plate 12 to move toward or in opposite directions along the photovoltaic power generation panel 9, but also allows the hot steam to act on the photovoltaic surface of the photovoltaic power generation panel 9 through the movement of the first purification plate 11 and the second purification plate 12. At the same time, the mechanical energy generated by the generator 14 is converted into electrical energy, so that thermal energy is converted into electrical energy, achieving energy saving.
