[0031] Reference Figure 1-Figure 10An adjustable building lighting skylight sunshade device comprises a skylight body 1 and an installation frame 2, wherein the installation frame 2 is arranged on the outer surface of the skylight body 1 close to the outdoors, a transparent glass 25 is arranged between the inner walls of the skylight body 1, a plurality of sunshades 5 are equidistantly rotatably installed between the inner walls of the opposite sides of the installation frame 2, the sunshades 5 are hollow, a plurality of air inlet holes 9 are evenly opened on the outer surface of the sunshade 5 close to the outdoors, the air inlet holes 9 are arranged on the outer surface at the middle position of the sunshade 5, a slide 6 is slidably installed on the inner wall of the sunshade 5 close to the air inlet holes 9, a plurality of through holes 13 are evenly opened on the outer surface of the slide 6, and the inner wall of the sunshade 5 close to the air inlet holes 9 is provided with a plurality of through holes 13, and the inner wall of the sunshade 5 close to the air inlet holes 9 is provided with a plurality of through holes 13. Two first limit pins 15 are fixedly installed on the wall, and two first limit slots 14 are provided on the outer surface of the slide 6. The two first limit pins 15 are slidably installed with the inner walls of the two first limit slots 14 respectively. A plurality of exhaust holes 10 are evenly penetrated through the top and bottom walls of the sun visor 5, and the outlet ends of the plurality of exhaust holes 10 are arranged above the skylight body 1. A slide rod 7 is fixedly installed at one end of the slide 6, and an end of the slide rod 7 away from the slide 6 penetrates through the outer surface of the sun visor 5 and is slidably installed on its inner wall. A plurality of fixed blocks 8 are equidistantly fixedly installed on the upper surface of the installation frame 2 near the slide rod 7, and the position of the slide rod 7 is limited by the fixed blocks 8 to facilitate the movement of the slide 6.

[0032] Due to the effect of wind force, the sun visor 5 will bend, so that the through hole 13 on the slide 6 is connected with the air inlet 9, and the wind will enter the interior of the sun visor 5 through the air inlet 9, and then blow out from the exhaust hole 10. Since the air outlet end of the exhaust hole 10 faces the direction of the transparent glass 25, and the exhaust hole 10 is set in a trumpet shape, a reaction force is formed. This reaction force will offset a part of the wind force acting on the sun visor 5, thereby ensuring that the sun visor 5 can avoid being damaged in strong wind weather, thereby preventing the sun visor 5 from being deformed, damaged and falling off; when strong wind enters the hollow part of the sun visor 5 through the air inlet 9, the air flow will flow inside and finally be discharged through the trumpet-shaped exhaust hole 10. This design makes the wind It can flow freely inside the sun visor 5, reducing the direct impact of wind on the surface of the sun visor 5; after the wind enters from the air inlet 9, part of the wind force will be absorbed and converted inside the sun visor 5, reducing the wind pressure directly acting on the surface of the sun visor 5, and through effective airflow guidance, it can achieve wind pressure balance to a certain extent, thereby reducing the load on the sun visor 5; the design of the trumpet-shaped exhaust hole 10 can help the airflow to be discharged more smoothly, thereby reducing eddy currents and aerodynamic resistance, which can not only reduce the wind force borne by the sun visor 5, but also improve its overall aerodynamic performance; due to the existence of internal airflow, it can play a certain buffering role, thereby improving the stability of the sun visor 5 under the action of wind force and reducing the risk of deformation and damage caused by wind pressure.

[0033] In this embodiment, a driving block 11 is fixedly installed on the outer surface of the mounting frame 2 at one end of the sun visor 5 away from the sliding rod 7, and a slide plate 4 is slidably installed on the outer surface of the mounting frame 2 close to the driving block 11. Two second limiting grooves 17 are provided on the outer surface of the slide plate 4, and two second limiting pins 18 are fixedly installed on the outer surface of one side of the mounting frame 2. The two second limiting pins 18 are respectively slidably installed on the inner walls of the two second limiting grooves 17. A driving column 12 is fixedly installed on the bottom end of the driving block 11, and a plurality of driving grooves 16 are equidistantly provided on the outer surface of the slide plate 4. The driving column 12 is slidably installed on the inner wall of the driving groove 16. An electric telescopic rod 3 is fixedly installed on the upper surface of the other side of the mounting frame 2, and the telescopic end of the electric telescopic rod 3 is fixedly connected to the outer surface of the slide plate 4, and the driving groove 16 and the center line of the slide plate 4 are arranged perpendicular to each other.

[0034] The telescopic movement of the telescopic end of the electric telescopic rod 3 drives the skateboard 4 to move back and forth, so that the skateboard 4 drives the driving slot 16 to move, and the driving slot 16 drives the driving block 11 to swing through the driving column 12. The driving block 11 drives the sun visor 5 to rotate within an angle range. The rotation of the sun visor 5 can adjust the gap between two adjacent sun visors 5, thereby adjusting the amount of sunlight penetrating the sun visor 5. The device can adjust the amount of sunlight penetrating the sun visor 5.

[0035] In this embodiment, two screw rods 19 are symmetrically rotatably installed between the inner walls on opposite sides of the mounting frame 2, and scrapers 20 are slidably installed on the outer surfaces of the two screw rods 19. The screw rods 19 are threadedly connected to the scrapers 20, and the scrapers 20 are arranged below the sun visor 5. The scrapers 20 are against the upper surface of the transparent glass 25. The outer surfaces of the two screw rods 19 near one end of the slide plate 4 are fixedly installed with driven gears 24, and the outer surface of the mounting frame 2 near one side of the driven gear 24 is rotatably installed with two transmission gears 23. The two transmission gears 23 are respectively meshed with the two driven gears 24, and the ends of the two transmission gears 23 near the slide plate 4 are both penetrated by the outer surface of the mounting frame 2 and fixedly installed with driving gears 22. The upper surfaces of the slide plate 4 near both ends are fixedly installed with racks 21, and the racks 21 are meshed with the driving gears 22.

[0036] The two racks 21 are driven by the slide plate 4 to move, the racks 21 drive the driving gear 22 to rotate, the driving gear 22 drives the transmission gear 23 to rotate, and the transmission gear 23 drives the screw rod 19 to rotate through the driven gear 24, so that the screw rod 19 drives the scraper 20 to slide along the outer surface of the transparent glass 25 to scrape off the dust on its outer surface, and the scraped dust runs out from the gap between the sun visors 5 under the blowing of external wind. Through this device, when the sun visor 5 is just opened, the electric telescopic rod 3 can move back and forth for a stroke, so that the scraper 20 can scrape the outer surface of the transparent glass 25 clean, thereby facilitating the entry of light.

[0037] It should be noted that when the present invention is in use, the telescopic movement of the telescopic end of the electric telescopic rod 3 drives the skateboard 4 to move back and forth, so that the skateboard 4 drives the driving slot 16 to move, and the driving slot 16 drives the driving block 11 to swing through the driving column 12, and the driving block 11 drives the sun visor 5 to rotate within an angle range. The rotation of the sun visor 5 can adjust the gap between two adjacent sun visors 5, thereby adjusting the amount of sunlight penetrating the sun visor 5. The device can adjust the amount of sunlight penetrating the sun visor 5; at the same time, the two racks 21 are driven to move by the skateboard 4, the racks 21 drive the driving gear 22 to rotate, the driving gear 22 drives the transmission gear 23 to rotate, and the transmission gear 23 drives the screw rod 19 to rotate through the driven gear 24, so that the screw rod 19 drives the scraper 20 to slide along the outer surface of the transparent glass 25 to scrape off the dust on its outer surface, and the dust is scraped off. Under the influence of external wind force, the wind will run out from the gap between the sun visors 5. Through the present device, when the sun visor 5 is just opened, the electric telescopic rod 3 can move back and forth for a stroke, so that the scraper 20 can scrape the outer surface of the transparent glass 25 clean, which is convenient for light to enter; when the sun visor 5 encounters strong wind, the sun visor 5 will bend due to the action of wind force, so that the through hole 13 on the slide 6 is connected with the air inlet 9, and the wind will enter the interior of the sun visor 5 through the air inlet 9, and then blow out from the exhaust hole 10. Since the air outlet end of the exhaust hole 10 faces the direction of the transparent glass 25, and the exhaust hole 10 is set in a trumpet shape, a reaction force is formed. This reaction force will offset part of the wind force acting on the sun visor 5, thereby ensuring that the sun visor 5 can avoid being damaged in strong wind weather, thereby preventing the sun visor 5 from being deformed, damaged and falling off.
