[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, by providing a photosensitive sensor, a working motor, a driving gear, a rack, a movable disk, a fixed disk, a pushing groove, a strip-shaped groove, a baffle, a first movable rod, a second movable rod and an arc-shaped opening, the staff can control the working motor by starting the working motor or through the photosensitive sensor, so that the working motor can drive the driving gear to rotate. The meshing of the driving gear and the rack enables the driving gear to push the rack to slide within the arc-shaped opening, and the pushed rack will drive the movable disk, causing the connecting ring to slide within the annular groove on the inner wall of the daylighting and ventilation cylinder, so that the movable disk can rotate within the daylighting and ventilation cylinder. When the movable disk rotates, the arc-shaped pushing groove will push the first movable rod, enabling the first movable rod to drive the baffle to move, and further enabling the second movable rod to slide within the strip-shaped groove, so that multiple baffles can offset and slide between the movable disk and the fixed disk, and then jointly block the light-transmitting and ventilation holes through the multiple baffles. Thus, the environmental light source is sensed through the photosensitive sensor, and the movement of the baffles is dynamically controlled in real time to adjust the size of the light-transmitting and ventilation holes, improving the actual use effect and enhancing the environmental comfort level.

[0017] 2. In the present invention, by providing a guiding chute, a connecting spring, a slider, a limiting rod, a daylighting cover, a connecting plate, an arc-shaped groove, a first limiting groove and a second limiting groove, during assembly, the staff sleeved the daylighting cover on one end of the daylighting and ventilation cylinder. At this time, the connecting plate will contact one end of the daylighting and ventilation cylinder, and the limiting rod can be inserted into the first limiting groove. Then, by screwing the daylighting cover, the daylighting cover is threadedly connected to the daylighting and ventilation cylinder. When the daylighting cover rotates, the inclined first limiting groove will push the limiting rod, causing the slider to slide within the guiding chute and compress the connecting spring. The pushed limiting rod will slide into the arc-shaped groove and move within the arc-shaped groove as the daylighting cover rotates. When the limiting rod moves to the second limiting groove at one end of the arc-shaped groove, the connecting spring will push the slider to move, causing the limiting rod to be stuck in the second limiting groove, thereby restricting the daylighting cover through the limiting rod to prevent the daylighting cover from accidentally rotating, and further improving the stability of the threaded connection between the daylighting cover and the daylighting and ventilation cylinder.

[0018] 3. In the present invention, by providing a fixed table, a guide groove, a threaded lead screw, a handwheel, a moving block, a threaded sleeve and a clamping plate, after the daylighting and ventilation cylinder is pushed onto the curtain wall unit, the operator rotates the threaded lead screw by turning the handwheel, causing the moving block to move in the guide groove by the threaded fit between the threaded sleeve and the threaded lead screw. The threads at both ends of the threaded lead screw with opposite directions enable the two moving blocks to move towards each other, thereby driving the two clamping plates to move on the fixed table, prompting the two clamping plates to clamp and fix the daylighting and ventilation cylinder, preventing the daylighting and ventilation cylinder from moving and falling. The operation is simple and convenient, and there is no need to fix the daylighting and ventilation cylinder with bolts and screws again, thus avoiding damage to the curtain wall unit caused by unscrewing bolts during disassembly and maintenance of the daylighting and ventilation cylinder, improving the disassembly and maintenance efficiency, and when the clamping plate clamps the daylighting and ventilation cylinder, it can block the guide groove, thereby protecting the threaded lead screw.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The technical solution of the present application will be further described in detail below in conjunction with specific embodiments.

[0028] As Figure 1-7 shown, the present invention provides a technical solution: an adaptive light source-changing ventilation and daylighting adjustment device for building curtain walls, including a curtain wall unit 1 and a daylighting and ventilation cylinder 2. The daylighting and ventilation cylinder 2 is installed in the curtain wall unit 1. One end of the daylighting and ventilation cylinder 2 is threadedly fitted with a daylighting cover 4. A connecting plate 26 is connected to the daylighting cover 4. Two arc-shaped grooves 27 are symmetrically arranged at the center of the connecting plate 26. One end of the arc-shaped groove 27 is inclined with a first limiting groove 28, and the other end of the arc-shaped groove 27 is horizontally provided with a second limiting groove 29. On both sides of one end of the daylighting and ventilation cylinder 2, guiding sliding grooves 11 are provided. A connecting spring 12 is connected in the guiding sliding groove 11. One end of the connecting spring 12 is connected with a slider 13. A limiting rod 14 is connected to the slider 13. The limiting rod 14 slides in the arc-shaped groove 27, and a thread is provided on the limiting rod 14.

[0029] When the daylighting cover 4 is screwed to be threadedly connected with the daylighting and ventilation cylinder 2, the connecting spring 12 will push the slider 13 to make the limiting rod 14 snap into the second limiting groove 29, thereby fixing and restricting the daylighting cover 4 to avoid accidental rotation. And at this time, the staff can also screw a nut onto the limiting rod 14 to urge the nut to tightly press and fix the connecting plate 26, thereby further improving the connection stability.

[0030] A connecting ring 30 is connected to the movable disk 7. An annular groove is provided on the inner wall of the daylighting and ventilation cylinder 2. Both the connecting ring 30 and the annular groove are of T-shaped design, and the connecting ring 30 is arranged in the annular groove on the inner wall of the daylighting and ventilation cylinder 2, so that the movable disk 7 is rotatably connected inside the daylighting and ventilation cylinder 2. Through the sliding of the T-shaped connecting ring 30 in the annular groove on the inner wall of the daylighting and ventilation cylinder 2, the movable disk 7 can stably rotate in the daylighting and ventilation cylinder 2. A diffuser plate 5 is connected to the inner wall of the daylighting and ventilation cylinder 2, and the diffuser plate 5 can diffuse light, so as to better cover the indoor space and improve the light utilization rate.

[0031] A working motor 9 is fixedly installed on the daylighting and ventilation cylinder 2. A driving gear 10 is installed on the output shaft of the working motor 9. An arc-shaped opening 32 is provided on the daylighting and ventilation cylinder 2. A rack 15 is connected to the movable disk 7. The rack 15 is arranged in the arc-shaped opening 32, and the rack 15 is of arc-shaped design. The overall length of the arc-shaped opening 32 is twice the length of the rack 15. The driving gear 10 is meshed with the rack 15. Through the meshing of the driving gear 10 and the rack 15, when the working motor 9 rotates the driving gear 10, the rack 15 can be driven to move, thereby causing the movable disk 7 to rotate.

[0032] A plurality of pushing grooves 16 are formed in the movable disk 7, and the pushing grooves 16 are arc-shaped as a whole; a fixed disk 6 is connected inside the daylighting and ventilation cylinder 2, and a plurality of strip-shaped grooves 31 are formed in the fixed disk 6. The pushing grooves 16 and the strip-shaped grooves 31 are respectively inclined on the movable disk 7 and the fixed disk 6; a first movable rod 17 is slidably connected in the pushing groove 16, and a baffle 18 is connected to the first movable rod 17. The baffle 18 is designed as a sector, and the baffle 18 is arranged between the movable disk 7 and the fixed disk 6. By arranging the baffle 18 between the movable disk 7 and the fixed disk 6, the movable disk 7 and the fixed disk 6 can limit the baffle 18, thereby preventing the baffle 18 from skewing and enabling the baffle 18 to move smoothly. A second movable rod 19 is connected to the baffle 18, and the second movable rod 19 slides in the strip-shaped groove 31.

[0033] Light-transmitting and ventilation holes are provided on the movable disk 7, the fixed disk 6, and the daylighting cover 4. When the movable disk 7 rotates, a plurality of pushing grooves 16 will simultaneously push a plurality of baffles 18 through the first movable rods 17, pushing the baffles 18 to slide, causing the second movable rods 19 to move in the strip-shaped grooves 31, so that a plurality of baffles 18 gradually block the light-transmitting and ventilation holes, and the baffles 18 block the light-transmitting and ventilation holes, and then the size of the light-transmitting and ventilation holes is adjusted by controlling the movement of the baffles 18 to meet the actual requirements.

[0034] A fixed platform 3 is connected to the curtain wall unit 1. A guide groove 20 is formed in the fixed platform 3. A threaded screw rod 21 is rotatably connected in the guide groove 20. One end of the threaded screw rod 21 passes through the fixed platform 3 and is connected with a hand wheel 22. Two moving blocks 23 are installed on the threaded screw rod 21. A threaded sleeve 24 is connected to the moving block 23. Opposite threads are provided at both ends of the threaded screw rod 21 to form a bidirectional screw rod. The threaded sleeve 24 is in threaded cooperation with the threaded screw rod 21. The moving block 23 slides in the guide groove 20 and contacts the groove wall.

[0035] A clamping plate 25 is connected to the moving block 23. The opposite sides of the clamping plate 25 are arc-shaped and connected with rubber pads 33. The clamping plate 25 penetrates through the sliding groove at the top of the fixed platform 3. The width of the clamping plate 25 is greater than the width of the moving block 23, and the clamping plate 25 contacts the upper part of the fixed platform 3. By the contact between the moving block 23 and the groove wall of the guide groove 20, the guide groove 20 can guide the movement of the moving block 23, and the contact between the clamping plate 25 and the upper part of the fixed platform 3 enables the fixed platform 3 to support the clamping plate 25 and block the guide groove 20 through the clamping plate 25, reducing the contact between the threaded screw rod 21 and the outside. When the two clamping plates 25 contact the daylighting and ventilation cylinder 2, the rubber pads 33 will be squeezed and deformed, so as to fit with the daylighting and ventilation cylinder 2 to increase friction and improve the clamping stability of the clamping plate 25.

[0036] A fixed block 34 is connected below the fixed table 3. Fixing holes are formed in the fixed block 34. The working motor 9 and the driving gear 10 are both arranged inside the protective shell 8. By screwing bolts into the fixing holes on the fixed block 34, the fixed table 3 can be fixed on the curtain wall unit 1.

[0037] A protective shell 8 is connected to the daylighting and ventilation cylinder 2. The working motor 9 and the driving gear 10 are both arranged inside the protective shell 8, enabling the protective shell 8 to protect the working motor 9 and the driving gear 10 and reduce their contact with the external environment. A photosensitive sensor 35 is installed on the protective shell 8. A power interface is arranged on the protective shell 8, and the power interface is electrically connected to the working motor 9 and the photosensitive sensor 35 respectively. The photosensitive sensor 35 can be used to detect the ambient light in real time.

[0038] The working principle of the present invention is as follows:

[0039] The staff sleeved the daylighting cover 4 on one end of the daylighting and ventilation cylinder 2, causing the connecting plate 26 to contact the daylighting and ventilation cylinder 2. At this time, the limiting rod 14 can be inserted into the first limiting groove 28. Then, by turning the daylighting cover 4, the daylighting cover 4 is threadedly connected to the daylighting and ventilation cylinder 2. At the same time, the inclined first limiting groove 28 will push the limiting rod 14, causing the slider 13 to slide in the guiding chute 11 and compress the connecting spring 12. The pushed limiting rod 14 will slide into the arc groove 27 and move in the arc groove 27 as the daylighting cover 4 rotates. When the limiting rod 14 moves to the second limiting groove 29 at one end of the arc groove 27, the connecting spring 12 will push the slider 13 to move, causing the limiting rod 14 to be stuck in the second limiting groove 29, thereby restricting the daylighting cover 4 through the limiting rod 14 and preventing the daylighting cover 4 from accidentally rotating.

[0040] Then, the daylighting and ventilation cylinder 2 is pushed onto the curtain wall unit 1, and by turning the handwheel 22 to rotate the threaded lead screw 21, the two moving blocks 23 drive the two clamping plates 25 to move towards each other, so that the two clamping plates 25 clamp and fix the daylighting and ventilation cylinder 2, thereby preventing the daylighting and ventilation cylinder 2 from moving and falling.

[0041] When working, the photosensitive sensor 35 can perform photosensitive detection and control the working motor 9, so that the working motor 9 can drive the driving gear 10 to rotate; the rotating driving gear 10 can then push the rack 15 to slide within the arc-shaped opening 32, prompting the rack 15 to drive the movable disk 7 to rotate within the daylighting and ventilation cylinder 2. When the movable disk 7 rotates, the arc-shaped pushing groove 16 will push the first movable rod 17, enabling the first movable rod 17 to drive the baffle 18 to move. Furthermore, the second movable rod 19 will slide within the strip-shaped groove 31, so that multiple baffles 18 can shift and slide between the movable disk 7 and the fixed disk 6. Then, the light-transmitting and ventilation holes are blocked jointly by the multiple baffles 18. Thus, the photosensitive sensor 35 senses the ambient light source and dynamically controls the movement of the baffle 18 in real time to adjust the size of the light-transmitting and ventilation holes.
