[0034] Working principle: during installation, the device is installed on the door head by bolts, and then the threaded cylinder 412 is rotated by inserting a hard column into the toggle plug ring 413. When the threaded cylinder 412 rotates, the telescopic length of the threaded column 414 is adjusted through the thread, and then the angle between the side shell 301 and the main support frame 101 is adjusted, so as to achieve fine adjustment of the main support frame 101.

The liquid pump 506 pumps the black oil in the liquid storage box 501 into the buffer box 502, and then enters the liquid guide channel 103 from the buffer box 502, and then gradually fills the fluid gap. The squeezed nitrogen in the fluid gap enters the air bag 601 from the air guide channel 102. At the same time, negative pressure is formed inside the liquid storage box 501, and the rubber diaphragm 503 shrinks. At this time, the fluid gap is filled with black oil, and the light transmittance becomes poor, so that the device can shade the sun; When light is transmitted, the electromagnetic valve 504 is opened, the liquid storage box 501 and the buffer box 502 are connected, and the rebound tension of the rubber diaphragm 503, the atmospheric negative pressure, the nitrogen expansion pressure and the rebound pressure of the airbag 601 work together to push the nitrogen into the fluid gap, and the black oil inside the fluid gap is squeezed and flows back to the liquid storage box 501 and the buffer box 502, and then the electromagnetic valve 504 is closed. At this time, the fluid gap is filled with nitrogen, and the light transmittance of the fluid gap becomes stronger to avoid sunshade; When cleaning, start the cleaning motor 217, and the cleaning motor 217 drives the driving wheel 219 through the output shaft 218, and then drives the driven wheel 216 through the synchronous belt 220 to rotate the transmission shaft 213, and then the transmission shaft 213 drives the edge banding belt 210 to move through the pulley 209. When the edge banding belt 210 moves, it drives the translucent cloth 211 to move, so that foreign objects such as leaves, garbage and cobwebs on the surface of the translucent cloth 211 are all driven, and these foreign objects will fall directly when reaching the edge. At the same time, the moving translucent cloth 211 is brushed and cleaned by the brush 222 to ensure that the surface of the brush 222 is cleaned.
