[0004] Existing energy-saving modular houses mostly use simple ventilation openings, which have poor ventilation effects and cannot effectively achieve rapid air renewal inside the modular house, resulting in poor indoor air circulation and affecting the comfort of living or working. Therefore, a ventilation structure for energy-saving modular houses is proposed to solve the above problems. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a ventilation structure for energy-saving modular houses. (Refer to...) Figure 1-5 A ventilation structure for energy-saving modular houses includes a mounting frame 1, a guide hood 2, a mounting ring 3, a ventilation fan 4, a guide mechanism, and an airflow control mechanism. The mounting frame 1 serves as the basic load-bearing component of the entire ventilation structure. One side of its outer wall is fixedly connected to the guide hood 2 by welding or bolting. The side of the guide hood 2 facing away from the mounting frame 1 is also fixed to the mounting ring 3 by welding or bolting. The side of the mounting ring 3 facing away from the guide hood 2 is fixed to the ventilation fan 4 by screws. The interior of the mounting frame 1 is provided with a guide mechanism for adjusting the airflow direction. The outer wall of the mounting ring 3 is provided with an airflow control mechanism for controlling the airflow. The airflow control mechanism is located between the mounting ring 3 and the ventilation fan 4.

[0024] The flow guiding mechanism includes components such as a flow guide plate 5, a connector 7, a connecting rod 8, and an electric telescopic rod 10. The flow guide plate 5 extends horizontally, and multiple flow guide plates 5 are distributed vertically and arranged parallel to each other. They are rotatably connected to the inner wall of the mounting frame 1 by a rotating shaft 6. During specific assembly, shaft holes are opened at corresponding positions on the inner wall of the mounting frame 1. The rotating shaft 6 passes through the center of the flow guide plate 5, and its two ends are inserted into the shaft holes of the mounting frame 1, so that the flow guide plate 5 can rotate freely around the rotating shaft 6. After the two ends of the rotating shaft 6 pass through the mounting frame 1, they are fixed to the connector 7 by welding. The ends of multiple connectors 7 opposite to the rotating shaft 6 are hinged to the same connecting rod 8 through hinge shafts to ensure that the connectors 7 and the connecting rod 8 can rotate relative to each other. One side of the outer wall of the mounting frame 1 is fixed to the mounting plate 9 by welding. The outer wall of the mounting plate 9 is movably connected to the electric telescopic rod 10 through a shaft seat. The telescopic end of the electric telescopic rod 10 is hinged to the connecting rod 8 through a movable part 11.

[0025] When the ventilation direction needs to be adjusted, the electric telescopic rod 10 is activated, and the electric telescopic rod 10 begins to extend and retract. Its extension end pulls or pushes the connecting rod 8 through the movable part 11. Since the connecting rod 8 is hinged to multiple connecting parts 7, during the movement of the connecting rod 8, it will drive the connecting parts 7 to rotate around the connection point with the rotating shaft 6, thereby causing multiple guide plates 5 to rotate synchronously. For example, when the electric telescopic rod 10 extends, the connecting rod 8 moves away from the mounting plate 9, and the guide plate 5 will deflect in a certain direction, changing the angle at which the airflow enters the energy-saving container room. When the electric telescopic rod 10 shortens, the guide plate 5 rotates in the opposite direction, realizing flexible adjustment of the ventilation direction to meet different ventilation needs.

[0026] The airflow control mechanism includes a second rotating shaft 15, adjusting flaps 16, gear 19, and a rotary drive assembly. The rotary drive assembly includes a servo motor 21, gear 22, and an external gear ring 13. Multiple adjusting flaps 16 are evenly distributed in a circumferential array inside the mounting ring 3. The second rotating shaft 15 is radially fixed and passes through the adjusting flaps 16, with both ends protruding from the flaps. Through holes are opened at corresponding positions on the mounting ring 3. The end of the second rotating shaft 15 furthest from the center of the mounting ring 3 extends through the through holes to the outside of the mounting ring 3 and is fixedly connected to gear 19. The servo motor 21 is fixedly mounted on the outer circumference of the mounting ring 3 via a mounting bracket 20. The mounting bracket 20 is connected to the mounting ring 3 by welding or bolts. The output shaft of the servo motor 21 passes through the mounting bracket 20 and then engages with the gear 19. Gear 22 is fixedly connected. The outer circumferential wall of the mounting ring 3 is provided with an annular groove. The shaft collar 12 is rotatably connected in the groove through a bearing. The outer circumferential wall of the shaft collar 12 is fixedly connected to the external gear ring 13 through multiple connecting columns. The external gear ring 13 meshes with gear 22. A spur gear ring 14 is welded to the outer wall of the side of the external gear ring 13 facing the guide shroud 2. The spur gear ring 14 meshes with multiple gears 19. Multiple fixing rods 17 are fixedly welded to the inner wall of the mounting ring 3. The multiple fixing rods 17 extend radially along the mounting ring 3. A connecting block 18 is welded to the end of the multiple fixing rods 17 that is close to each other. The ends of multiple rotating shafts 15 that are away from gears 19 are rotatably connected to the outer wall of the connecting block 18 through a bearing, providing stable rotational support for the adjusting valve 16.

[0027] When ventilation volume needs to be adjusted, servo motor 21 is started. Servo motor 21 is powered on and its output shaft drives gear 22 to rotate. Since gear 22 meshes with external gear ring 13, the rotation of gear 22 will drive external gear ring 13 to rotate around the circumference of mounting ring 3. External gear ring 13 drives shaft ring 12 to rotate synchronously in the groove of mounting ring 3 through connecting column. When external gear ring 13 rotates, spur gear ring 14 welded to one side also rotates. Spur gear ring 14 meshes with multiple gears 19, thereby driving gears 19 to rotate. The rotation of gears 19 causes adjusting petals 16 to rotate around their own axis through rotating shaft 15. Multiple adjusting petals 16 rotate synchronously, changing the size of the cross-sectional area of ​​the ventilation opening formed by them. For example, when servo motor 21 rotates forward, the rotation of adjusting petals 16 increases the cross-sectional area of ​​the ventilation opening and increases the ventilation volume. When servo motor 21 rotates in reverse, the rotation of adjusting petals 16 decreases the cross-sectional area of ​​the ventilation opening and reduces the ventilation volume, thereby achieving precise control of ventilation volume.

[0028] The edge of the regulating flap 16 is provided with a sealing strip (not shown in the figure). The sealing strip is made of silicone rubber. When installing the regulating flap 16, the silicone rubber sealing strip is fixed to the edge of the regulating flap 16 by adhesive or slot embedding. Due to the good elasticity, sealing and aging resistance of silicone rubber, the sealing strip between adjacent regulating flaps 16 can fit tightly during the process of adjusting the ventilation volume by rotating the regulating flap 16, effectively reducing air leakage and ensuring that the ventilation structure has a good sealing effect under different ventilation volume conditions, thereby improving the ventilation efficiency and energy-saving performance of the energy-saving container house.

[0029] The implementation principle of a ventilation structure for energy-saving modular houses according to an embodiment of this application is as follows: In actual use, the ventilation fan 4 is powered on and generates airflow, introducing outside air into the energy-saving modular house. When it is necessary to adjust the ventilation direction, the extension and retraction of the electric telescopic rod 10 is controlled, which drives the guide plate 5 of the airflow guiding mechanism to rotate, changing the direction of airflow entry. When it is necessary to adjust the ventilation volume, the servo motor 21 is started, and through a series of gear transmissions of the airflow control mechanism, the adjusting valve 16 is rotated, changing the cross-sectional area of ​​the ventilation opening, thereby achieving control of the ventilation volume. The two mechanisms work together to flexibly adjust the ventilation direction and ventilation volume according to the actual needs inside the energy-saving modular house, ensuring good air circulation and a comfortable environment inside the modular house.
