Description

Technical Field

[0001] This utility model relates to the field of double-layer curtain wall technology, specifically to a double-layer curtain wall air diversion energy-saving ventilation system. Background Technology

[0002] Double-layer curtain walls, also known as breathing curtain walls, are typically composed of an outer curtain wall, a thermal channel, and an inner curtain wall. The thermal channel allows for orderly airflow within the curtain wall, improving building performance. Currently, double-layer curtain walls represent a new type of energy-saving and environmentally friendly curtain wall, signifying a new development in curtain wall technology.

[0003] Common double-layer curtain wall structures have ventilation openings installed on the upper and lower sides of the curtain wall. In summer, the ventilation openings are opened to use the chimney effect to allow hot air to rise and be expelled, reducing the transfer of outdoor heat to the interior and lowering the air conditioning load. In winter, when insulation is needed, the ventilation openings are closed, and solar radiation is used to heat the air gap, creating a greenhouse effect, reducing indoor heat loss and heating losses. Some double-layer curtain wall structures also have exhaust fan structures to expel indoor stale air and remove heat from the space layer to achieve thermal insulation effects.

[0004] However, during the spring and autumn seasons, in overcast weather, or when the temperature difference between day and night is small, the indoor and outdoor temperature difference and wind force are small, which leads to a significant decrease in ventilation effect and affects ventilation efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a double-layer curtain wall airflow energy-saving ventilation system that can improve ventilation effect and efficiency when the indoor and outdoor temperature difference is small or the wind force is low.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a double-layer curtain wall air diversion energy-saving ventilation system, including a floor, an inner glass curtain wall, a first square steel, a second square steel and an outer glass curtain wall. A wind guide plate is provided between the two second square steels. Connecting strips are fixedly connected to the first square steels located on both sides of the outer glass curtain wall. The connecting strips are located on the side of the first square steels closer to the inner glass curtain wall. A connecting frame is rotatably connected between the two connecting strips. A ventilation groove is opened on the connecting frame. Dustproof nets are fixedly connected to both the upper and lower sides of the ventilation groove. A drive motor is fixedly connected to the upper end of the dustproof net on the upper side. A guide fan is fixedly connected to the output end of the drive motor. A connecting groove is opened at the end of the connecting frame away from the outer glass curtain wall. A connecting column is rotatably connected to the connecting groove through a rotating shaft. An electric push rod is fixedly connected to the bottom side of the connecting column. A support plate is rotatably connected to the bottom end of the electric push rod. The support plate is fixedly connected to the bottom floor.

[0007] As a preferred technical solution of this utility model, the air guide plate is in contact with a baffle on the side near the inner glass curtain wall, and the baffle on the side away from the air guide plate is in contact with a limiting rod. The limiting rod is threadedly connected to a first square steel. By setting the baffle, dust can be reduced from entering between the inner and outer glass curtain walls.

[0008] As a preferred technical solution of this utility model, the wind guide plate has rubber limiting strips on both the upper and lower sides of one end. The rubber limiting strips are fixedly connected between two corresponding second square steels. By setting the rubber limiting strips, a temporary limiting structure is formed, which facilitates the installation of the baffle.

[0009] As a preferred technical solution of this utility model, a fixing strip is fixedly connected to the bottom end of the connecting frame near the inner glass curtain wall, and a flexible rain shield is fixedly connected to one side of the fixing strip. One end of the flexible rain shield is fixedly connected to the second square steel on the bottom side. By setting the flexible rain shield, rainwater can be reduced from entering between the inner and outer glass curtain walls from the bottom wind guide plate.

[0010] As a preferred technical solution of this utility model, the bottom side of the flexible rain shield is in contact with an abutment rod, and both ends of the abutment rod are rotatably connected to sliders. An auxiliary rod is movably inserted into the slider, and a spring is sleeved on the bottom side of the auxiliary rod. The spring is located between the bottom floor and the slider. By setting the auxiliary rod, slider, abutment rod, spring, etc., the flexible rain shield can contact the barrier net when the connecting frame rotates and moves down, thereby reducing rainwater from entering between the inner glass curtain wall and the outer glass curtain wall.

[0011] This utility model has the following advantages: by setting a rotatable connecting frame, ventilation slot, drive motor and guide fan between the inner glass curtain wall and the outer glass curtain wall, a forced circulation is formed, which can improve the ventilation effect. At the same time, the rotation can make the airflow make angled contact with the inner and outer glass curtain walls, increasing the contact surface between the airflow and the inner cavity, further improving the ventilation effect.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The illustrated double-layer curtain wall airflow energy-saving ventilation system includes a floor 1, an inner glass curtain wall 2, a first square steel 3, a second square steel 4, and an outer glass curtain wall 5. A guide plate 6 is installed between the two second square steel 4s to guide airflow. Connecting strips 7 are fixedly connected to the first square steel 3s on both sides of the outer glass curtain wall 5, with the connecting strips 7 located on the side of the first square steel 3 closest to the inner glass curtain wall 2. A connecting frame 8 is rotatably connected between the two connecting strips 7s. A ventilation slot 9 is provided on the connecting frame 8, and dustproof nets 10 are fixedly connected to both the upper and lower sides of the ventilation slot 9. A drive motor 11 is fixedly connected to the upper end of the dustproof net 10 on the upper side, and a guide fan 12 is fixedly connected to the output end of the drive motor 11. A connecting groove 13 is provided at the end of the connecting frame 8 away from the outer glass curtain wall 5. The connecting groove 13 is rotatably connected to the connecting column 15 via the pivot 14. The connecting frame 8 is limited by the connecting strip 7, and the electric push rod 16 is limited by the support plate 17. When the electric push rod 16 extends, it can make the connecting frame 8 rotate. The electric push rod 16 is fixedly connected to the bottom side of the connecting column 15. The bottom end of the electric push rod 16 is rotatably connected to the support plate 17. The support plate 17 is fixedly connected to the bottom floor 1. When the electric push rod 16 extends, it can make the connecting frame 8 rotate, thereby changing the rotation angle of the connecting frame 8 and the guide fan 12, increasing the contact surface between the introduced airflow and the inner glass curtain wall 2 and the outer glass curtain wall 5, and improving the ventilation effect.

[0018] Among them, the air guide plate 6 is in contact with the baffle 18 on the side close to the inner glass curtain wall 2, and the baffle 18 is in contact with the limit rod 19 on the side away from the air guide plate 6. The limit rod 19 is threadedly connected to the first square steel 3. By setting the limit rod 19 and the baffle 18, the dust entering the airflow can be filtered.

[0019] Among them, the air guide plate 6 has rubber limiting strips 20 on both the upper and lower sides of one end. The rubber limiting strips 20 are fixedly connected between the corresponding two second square steels 4. By setting the rubber limiting strips 20, it is easy to temporarily fix the baffle 18, so as to facilitate the installation of the baffle 18.

[0020] Among them, a fixing strip 21 is fixedly connected to the bottom end of the connecting frame 8 near the inner glass curtain wall 2. A flexible rainproof plate 22 is fixedly connected to one side of the fixing strip 21. The flexible rainproof plate 22 is made of waterproof material. One end of the flexible rainproof plate 22 is fixedly connected to the second square steel 4 on the bottom side. By setting the flexible rainproof plate 22, a rainproof structure can be formed at the bottom wind guide plate 6 to reduce rainwater from entering between the inner glass curtain wall 2 and the outer glass curtain wall 5 (the same type of structure can be installed on the bottom side of the upper floor 1).

[0021] The flexible rain shield 22 has a bottom contact with an abutment rod 23. Both ends of the abutment rod 23 are rotatably connected to sliders 24. An auxiliary rod 25 is movably inserted into the slider 24. A spring 26 is sleeved on the bottom side of the auxiliary rod 25. The spring 26 is located between the bottom floor 1 and the slider 24. The abutment rod 23 contacts the bottom side of the flexible rain shield 22. Then, under the action of the auxiliary rod 25, the slider 24 and the spring 26, when the electric push rod 16 retracts, the flexible rain shield 22 can block the bottom wind guide plate 6, thus improving the waterproof effect.

[0022] Working principle: A wind deflector 6 is installed between the two floor surfaces 1 to provide natural airflow, while the baffle 18 filters dust. When the wind force is insufficient (a sensor can be set to monitor this), the electric push rod 16 extends to rotate the connecting frame 8 to a certain angle, which in turn drives the drive motor 11 to rotate the guide fan 12 and form a forced airflow structure, which can improve the ventilation effect between the inner glass curtain wall 2 and the outer glass curtain wall 5. When airflow is not required between the inner glass curtain wall 2 and the outer glass curtain wall 5, the flexible rain shield 22 contacts the bottom wind deflector 6 under the action of the spring 26, reducing the amount of rainwater entering between the inner glass curtain wall 2 and the outer glass curtain wall 5.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
