[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a sound-absorbing curtain wall structure, referring to Figures 1-4 , including a wall 1, an embedded groove 2 is opened in the middle of the wall 1, two ventilation slots 3 are opened on both sides of the bottom of the wall 1, two air duct adjustment plates 4 are provided on the inner sides of the two ventilation slots 3, and the middle parts of the two air duct adjustment plates 4 are fixedly connected with a rotating rod 5, and grooves 6 are opened at both ends of the ventilation slot 3. The two sides of the two rotating rods 5 are respectively rotatably connected to the inside of the two grooves 6, and one side surface of the two rotating rods is fixedly connected with a linkage gear 7. Two hidden slots 8 are opened at the bottom of both ends of the wall 1, and a servo motor 9 is installed on the inner side of the two hidden slots 8. The output end of the servo motor 9 passes through the hidden slot 8 and is connected to a bidirectional screw rod 10. The other end of the bidirectional screw rod 10 is rotatably connected to the inner bottom of the ventilation slot 3. Two rack plates 11 are threadedly connected to the two ends of the surface of the bidirectional screw rod 10. The servo motor 9 is used to drive the bidirectional screw rod 10 to rotate, so that the rack plates 11 threadedly connected to the two ends of the surface of the bidirectional screw rod 10 move. The inner sides of the two rack plates 11 are respectively engaged with the surfaces of the two linkage gears 7. The movement of the rack plates 11 drives the linkage gear 7 to rotate, and then the rotating rod 5 and the air duct adjustment plate 4 rotate, thereby changing the ventilation area of ​​the ventilation slot 3. In summer, the ventilation area can be increased, the ventilation effect can be enhanced, the indoor temperature can be reduced, and stuffy discomfort can be avoided; in winter, the ventilation area can be reduced, the ventilation volume can be appropriately controlled, fresh air can be introduced, the dryness of the indoor air can be improved, and the comfort of the indoor environment can be improved.

[0021] Reference Figures 1-4The other ends of the two rack plates 11 are fitted into the inner wall of the groove 6 to ensure the stability of its movement and will not rotate with the rotation of the bidirectional screw rod 10. The outer sides of the ventilation slots 3 are fixedly connected with concave seats 12, and the inner sides of the concave seats 12 are provided with wooden sound-absorbing panels 13. The setting of the wooden sound-absorbing panels 13 effectively absorbs sound when the ventilation slots 3 are not in use, reduces the spread of noise, and ensures the overall sound absorption effect of the wall 1. Both sides of the wooden sound-absorbing panels 13 are fixedly connected with insertion strips 14, and slots 15 are provided at both ends of the inner side of the concave seat 12. The wooden sound-absorbing panels 13 are inserted into the inner sides of the slots 15 through the insertion strips 14, which makes it convenient to remove the wooden sound-absorbing panels 13 at any time when the ventilation slots 3 are in use. The inner side of the embedded groove 2 is provided with polyurethane foam panels 17, aluminum honeycomb sound-absorbing panels 18 and glass fiber The sound-absorbing cotton 19, the polyurethane foam board 17, the aluminum honeycomb sound-absorbing board 18 and the glass fiber sound-absorbing cotton 19 work together to effectively absorb external noise, provide good sound absorption effect, and create a quiet and comfortable environment for the room. The four corners of the inner surface of the embedded groove 2 are fixedly connected with mounting screws 16, and the four corners of the polyurethane foam board 17, the aluminum honeycomb sound-absorbing board 18 and the glass fiber sound-absorbing cotton 19 are provided with mounting holes 20. The four mounting screws 16 respectively penetrate the mounting holes 20 on the surface of the polyurethane foam board 17, the aluminum honeycomb sound-absorbing board 18 and the glass fiber sound-absorbing cotton 19 and are connected with nuts, which facilitates the installation and removal of the sound-absorbing material. When the sound-absorbing material needs to be replaced or repaired, the nuts can be easily removed, the old sound-absorbing material can be taken out, and replaced or repaired, which improves the convenience of maintenance.

[0022] The implementation principle of a sound-absorbing curtain wall structure in an embodiment of the present application is as follows: during specific use, first, a polyurethane foam board 17, an aluminum honeycomb sound-absorbing board 18 and a glass fiber sound-absorbing cotton 19 are installed in the embedded groove 2 in the middle of the wall 1, and are fixed by installing screws 16 and nuts. These sound-absorbing materials can effectively absorb external noise and provide a good acoustic environment for the room. When the ventilation needs to be adjusted, the servo motor 9 in the hidden groove 8 is started, and the servo motor 9 drives the bidirectional screw rod 10 to rotate. The rack plates 11 at both ends of the surface of the bidirectional screw rod 10 move along the bidirectional screw rod 10 under the action of the thread. Since the inner side of the rack plate 11 is meshed with the linkage gear 7, the movement of the rack plate 11 will drive the linkage gear 7 to rotate, and then the rotating rod 5 and the air duct adjustment plate 4 will rotate to realize the adjustment of the air duct. When the rack plate 11 moves outward, the air duct adjustment plate 4 rotates. When the two air duct adjustment plates 4 remain horizontal, the ventilation area of ​​the ventilation slot 3 is increased, thereby enhancing the ventilation effect.
