[0003] When the existing building ventilation is in use, a filter screen is generally provided. The filter screen is to prevent impurities in the air from entering the ventilator. However, there are some deficiencies: the filter screen of the ventilator is not convenient to disassemble and clean. After long-term ventilation, a large amount of dust and impurities will adhere to the filter screen, affecting the ventilation effect. Moreover, the ventilator components are located inside the air duct, which is not convenient for disassembling, installing and overhauling the ventilator components. Therefore, improvements are needed. Content of the Utility Model

It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0020] As Figures 1-3 , a green building energy-saving ventilation structure of the present utility model includes an air duct 1. Wind covers 2 are provided at both ends of the air duct 1. A limiting device 5 is provided on the inner wall of the wind cover 2. A filter net 3 is provided inside the wind cover 2. A fixing plate 4 is provided inside the filter net 3. A locking device 7 is provided inside the fixing plate 4. A ventilation component 6 is provided inside the air duct 1;

[0021] As Figures 1-2 , the locking device 7 includes a pin rod 8. The pin rod 8 is arranged in a rectangular plate shape. The pin rod 8 slides inside the fixing plate 4. A lead screw 9 rotates inside the fixing plate 4. A limiting plate 20 is provided inside the fixing plate 4. The lead screw 9 rotates inside the limiting plate 20. The limiting plate 20 can limit the lead screw 9 left and right. The lead screw 9 is threadedly connected to the pin rod 8. A worm gear 10 is provided on the lead screw 9. A worm 11 rotates on the fixing plate 4. The worm 11 is meshed and connected to the worm gear 10. A hand wheel 12 is provided on the worm 11. By turning the hand wheel 12 to screw the worm 11, the worm 11 meshes with the worm gear 10 to rotate, and the lead screw 9 will drive the pin rod 8 to extend out of the fixing plate 4 and insert into the inner wall of the wind cover 2 to complete the quick installation of the filter net 3.

[0022] As Figure 1 , the ventilation component 6 includes a mounting hole 13. The mounting hole 13 is located inside the upper end of the air duct 1. Embedding grooves 14 are provided on both sides of the upper end of the mounting hole 13. A frame 15 is inserted into the mounting hole 13. A ventilator 16 is provided inside the frame 15. Ear plates 17 are provided on both sides of the upper end of the frame 15. The ear plates 17 can fall into the embedding grooves 14. By fastening the ear plates 17 in the embedding grooves 14 with bolts, the quick installation and disassembly of the ventilator 16 can be realized, which is convenient for maintenance and repair.

[0023] As Figure 1 and 3, the limiting device 5 includes a baffle 18 which is arranged on the inner wall of the air hood 2. There are slots 19 on the inner wall of the air hood 2, and two groups of slots 19 are symmetrically arranged. The setting of the lead screw 9 can meet the opposite movement of the pin rods 8 on both sides, and the pin rods 8 can be inserted into the slots 19. When the baffle 18 blocks the filter net 3, the pin rods 8 are aligned with the slots 19, and the installation and fixation of the filter net 3 can be quickly completed.

[0024] During specific use, when installing the ventilator 16, the ventilator 16 is integrated inside the frame 15.

The ear plate 17 can be fastened by bolts.

[0025] When installing the filter net 3, the filter net 3 is inserted by aligning it with the air damper. The baffle 18 will block the filter net 3. At this time, the slots 19 and the pin rods 8 are in an aligned state. Then, turn the handwheel 12, and the worm 11 meshes with the worm wheel 10 to rotate. The worm wheel 10 drives the lead screw 9 to rotate in the limiting plate 20. The lead screw 9 will not move left and right. The lead screw 9 will drive the pin rods 8 to extend out from the fixed plate 4 and insert into the slots 19. In this way, the installation and fixation of the filter net 3 are completed, which is very convenient. The filter net 3 will filter the impurities in the air. If it is necessary to disassemble the filter net 3 for cleaning, just turn the handwheel 12, and the pin rods 8 can be disengaged from the slots 19, realizing the disassembly of the filter net 3, which is very convenient.
