[0034] The present invention provides an energy-saving ventilation device for a building facade, and its working principle is as follows: a ventilation device of the device is installed on the facade wall as a prerequisite, and absorbs and stores energy through light energy during the day to assist the operation of the device. The device enters and exhausts air through a common rectangular duct fan 103. During the day, the first photovoltaic panel drive mechanism 2 starts the motor 205, and its output shaft drives the bevel gear A206 when it rotates, and the bevel gear A206 drives the bevel gear B207 to rotate. When the bevel gear B207 rotates, it drives the gear A209 to rotate through the shaft A208. The gear A209 simultaneously drives the gear shaft A210 and the gear shaft C212 to rotate. When the gear shafts A210 and C212 rotate, the gear shaft A210 drives the gear shaft B211 to rotate. Gear shaft C212 drives gear shaft D213 to rotate, and when gear shaft B211 and gear shaft D213 rotate, they drive combined gear shaft 214 to rotate, wherein combined gear shaft 214 is composed of gear shafts welded with sprockets. When combined gear shaft 214 rotates, the middle connecting shaft rotates along the gear fixing plate 215, and the output torque of the sprocket part of combined gear shaft 214 is increased through several sets of gears. Its purpose is to protect components and increase their service life when supporting relatively heavy structures. Compared with motors with large load and large torque, it also reduces cost expenditure. When combined gear shaft 214 rotates, it drives sprocket 218 to rotate through chain A216 and chain B217. When sprocket 218 rotates, it drives cover plate 301 to rotate through shaft B219, and cover plate 301 drives the entire second The photovoltaic panel drive mechanism 3 rotates. When the second photovoltaic panel drive mechanism 3 rotates to the set maximum angle, the air inlet and outlet of the rectangular air duct A102 are unobstructed. If the air volume needs to be adjusted, the rotation angle of the second photovoltaic panel drive mechanism 3 and the first photovoltaic panel drive mechanism 2 is adjusted. This can control the air volume and ensure that the air inlet direction is oblique from bottom to top. In rainy and snowy weather, the second photovoltaic panel drive mechanism 3 can act as a sloped rain shield. When the second photovoltaic panel drive mechanism 3 rotates to a certain direction, the angular position of the photovoltaic assembly A339 and the photovoltaic assembly B341 can also be adjusted to maximize the sunlight and obtain the maximum solar energy. When the electric push rod A310 and the electric push rod B319 are started, the electric push rod A310 outputs The output shaft retracts downward, and when it retracts, it drives the spring fixing block B309 to slide downward along the limit bracket A302. The spring fixing block B309 drives the driving plate B306 to rotate along the limit bracket A302 through the driving plate A305. At the same time, the output shaft of the electric push rod B319 retracts downward, and when it retracts, it drives the spring fixing block C318 to slide downward along the limit bracket B311. The spring fixing block C318 drives the driving plate D315 to rotate along the limit bracket B311 through the driving plate C314. The driving plates B306 and D315 synchronously drive the photovoltaic panel fixing plate A338 to rotate. The photovoltaic panel fixing plate A338 drives the photovoltaic module A339 to rotate to an angle that caters to the sunlight. When the electric push rods C328 and D337 are started,The output shaft of electric push rod C328 retracts downward, driving spring fixing block D327 to slide downward along limit bracket C320. Spring fixing block D327 drives drive plate F324 to rotate along limit bracket C320 via drive plate E323. Simultaneously, the output shaft of electric push rod D337 retracts downward, driving spring fixing block H336 to slide downward along limit bracket D329. Spring fixing block H336 drives drive plate H333 to rotate along limit bracket D329 via drive plate G332. Drive plates F324 and H333 simultaneously drive photovoltaic panel fixing plate B340 to rotate. PV panel fixing plate B340 drives photovoltaic module B341 to rotate to an angle that meets the sunlight.
