[0021] An energy-saving billboard includes a billboard body 1, wherein the billboard body 1 is provided with at least two fan blades 3, wherein the fan blades 3 are provided through the billboard body 1 via a first rotating shaft 2, wherein the billboard body 1 is provided with electrical components and a coil spring 10 connected to the first rotating shaft 2, wherein the lower portion of the first rotating shaft 2 is connected to the middle end of the coil spring 10, wherein the outer end of the coil spring 10 is connected via a rotating sleeve 11, wherein the rotating sleeve 11 is transmission-connected to a second rotating shaft 14, wherein the second rotating shaft 14 is coaxially connected to an upper bevel gear 15, wherein the lower left and right sides of the upper bevel gear 15 are respectively meshed and transmission-connected to a left half bevel gear 16 and a right half bevel gear 17. The helical gear 17, the left half helical gear 16 and the right half helical gear 17 are coaxially connected to the third gear 19 through the third rotating shaft 18, and the third gear 19 is meshed with a first rack 20 on one side. The first rack 20 is connected to a moving rod 21, and the end of the moving rod 21 is slidably connected to an air cylinder 22 through a piston 23. The lower end of the air cylinder 22 is connected to an air inlet pipe 24 and an air outlet pipe 25. The other end of the air inlet pipe 24 is located on the outside of the billboard body 1, and the air outlet pipe 25 is located at the bottom of the billboard body 1. A heat dissipation port 26 is opened on the upper part of the billboard body 1, and a baffle 27 is hinged in the heat dissipation port 26. The baffle 2 7 is provided with a limit plate 28 fixedly connected to the heat dissipation port 26 on the outside, and an elastic spring 29 connected to the heat dissipation port 26 is provided on the inside of the baffle 27. When there is wind in the environment, the first rotating shaft 2 rotates, and the first rotating shaft 2 is connected to the second rotating shaft 14 through the outer end of the coil spring 10. The inner end of the coil spring 10 will be retracted, which is convenient for the energy storage process of the coil spring 10, and then slowly released to the second rotating shaft 14 through the rotating sleeve 11 at the outer end of the coil spring 10, so as to facilitate the more uniform rotation of the second rotating shaft 14. At the same time, when the first rotating shaft 2 does not rotate due to the lack of wind energy, the second rotating shaft 14 can also rotate under the action of the coil spring 10. The rotation of the second rotating shaft 14 drives the third rotating shaft 18 to rotate counterclockwise and then clockwise, so as to drive the first rack 20 to move up and down reciprocatingly, driving the outside air to enter the air cylinder through the air inlet pipe 24, and then be discharged into the billboard body 1 through the air outlet pipe 25. The cold air entering the billboard body 1 discharges the hot air in the billboard body 1 through the heat dissipation port 26, which is convenient for driving the circulation of air in the billboard body 1, facilitating the cleaning of the billboard body 1, and facilitating the discharge of hot air with dust through the heat dissipation port 26, thereby improving the use efficiency and further treating the heat dissipation of dust and electrical components inside the billboard.

[0022] In order to facilitate the adjustment of the angle of the fan blades 3, to adapt to different winds and improve energy saving, a first motor 5 is provided in the first rotating shaft 2. The output end of the first motor 5 is connected to a first bevel gear 7. One side of the first bevel gear 7 is meshed and connected to at least two second bevel gears 8 arranged at equal intervals. The second bevel gears 8 are connected one by one to the fan blades 3 through the connecting shaft 4.

[0023] In order to facilitate further energy-saving processing and improve the dust protection of the photovoltaic panel 32, a reflector 30 and a connecting frame 31 are provided on the fan blade 3, and a plurality of photovoltaic panels 32 arranged at equal intervals relative to the reflector 30 are provided on the connecting frame 31. Baffles are provided on both sides of the photovoltaic panel 32, and a ventilation duct is provided between the photovoltaic panel 32 and the reflector 30. The photovoltaic panel 32 is connected to a backup power supply. Light is irradiated to the reflector 30, and the light is reflected by the reflector 30 to the photovoltaic panel 32, which is convenient for energy storage. The setting of the ventilation duct facilitates the cleaning of dust and the like on the photovoltaic panel 32 and the reflector 30.

[0024] Two adjacent photovoltaic panels 32 are connected via a polarizer 33 . A polarizer 34 is provided on a side of the polarizer 33 close to the reflector 30 . The thickness of the polarizer 34 allows the light to be rotated by 30 degrees or 60 degrees.

[0025] In order to facilitate light to be irradiated onto the reflective element and reflected onto the photovoltaic panel 32 , the reflective element is a reflective film or a reflective plate attached to the fan blade 3 .

[0026] In order to facilitate the protection of the elastic spring 29, a first multi-section telescopic push rod is provided on the outer side of the elastic spring 29.

[0027] In order to facilitate the rotation of the coil spring 10 under the action of inertia, the lower part of the first rotating shaft 2 is connected to the middle end of the coil spring 10 by a weighted column 9. The first rotating shaft 2 rotates under the impetus of the fan blade 3 by the wind energy. The weighted column 9 makes the first rotating shaft 2 have a large inertia. In this way, when the wind force is large, the rotation acceleration of the first rotating shaft 2 is relatively slow. At the same time, the lower part of the weighted column 9 is connected to the middle end of the coil spring 10, and the outer end of the coil spring 10 is connected to the second rotating shaft through the rotating sleeve 11. 14. In this way, when the rotation speed of the weighted column 9 is faster, the inner end of the coil spring 10 will be retracted, so that the weighted column 9 will store energy in the coil spring 10, and then slowly release it to the second rotating shaft 14 through the rotating sleeve 11 at the outer end of the coil spring 10, so that the second rotating shaft 14 can rotate more evenly. At the same time, when the first rotating shaft 2 does not rotate due to the lack of wind energy, the second rotating shaft 14 can also rotate under the action of the coil spring 10, which is convenient for improving the use efficiency and further dissipating the heat of dust and electrical components inside the billboard.

[0028] When there is wind in the environment, the first rotating shaft 2 rotates, and the first rotating shaft 2 is connected to the second rotating shaft 14 through the outer end of the coil spring 10. The inner end of the coil spring 10 will be retracted, which is convenient for the energy storage process of the coil spring 10, and then slowly released to the second rotating shaft 14 through the rotating sleeve 11 at the outer end of the coil spring 10, so that the second rotating shaft 14 rotates more evenly. At the same time, when the first rotating shaft 2 does not rotate under the action of wind energy, the second rotating shaft 14 can also rotate under the action of the coil spring 10. The rotation of the second rotating shaft 14 drives the third rotating shaft 18 to rotate counterclockwise for a while and then for a while. Clockwise rotation facilitates the reciprocating motion of the first rack 20 moving up and down, driving the outside air to enter the air cylinder through the air inlet pipe 24, and then be discharged into the billboard body 1 through the air outlet pipe 25. The cold air entering the billboard body 1 discharges the hot air in the billboard body 1 through the heat dissipation port 26, which facilitates the circulation of air in the billboard body 1, facilitates the cleaning of the billboard body 1, and facilitates the discharge of hot air with dust through the heat dissipation port 26, which improves the use efficiency and further treats the heat dissipation of dust and electrical components inside the billboard.
