Description

Technical Field

[0001] This utility model relates to the field of curtain wall design technology, specifically an adjustable ventilated curtain wall structure. Background Technology

[0002] A ventilated curtain wall, also known as a double-layer curtain wall or a dynamic ventilated curtain wall, is a new type of energy-saving and intelligent glass curtain wall. It involves adding another glass curtain wall outside the traditional curtain wall, creating a relatively enclosed space called a thermal aisle or air gap. Air enters this space through the lower air inlet and exits through the upper air outlet, allowing heat to flow freely or circulate within the space.

[0003] When the air inlets and outlets of the ventilated curtain wall are working normally, they are in the open position. When the weather changes suddenly and there is a heavy rain, and the ventilation channel is not closed in time, the air inlet is at the bottom of the ventilated curtain wall, which is lower than the bottom edge of the window, so there is no need to worry about water leakage. However, the exhaust outlet is located at the top of the window. When the rain is heavy, especially when accompanied by strong winds, rainwater can easily seep in from the exhaust outlet, contaminating the exhaust channel and then entering the inner curtain wall. If the windows and doors are open at this time, rainwater can also easily enter the room, causing losses to the owner.

[0004] Therefore, this utility model provides an adjustable ventilated curtain wall structure to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This invention provides an adjustable ventilation curtain wall structure, which aims to solve the problems mentioned in the background art, such as rainwater easily entering the exhaust channel from the exhaust vent during heavy rain.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an adjustable ventilated curtain wall structure, comprising an inner curtain wall fixed to the exterior of a building near the building, an outer curtain wall fixed to the inner curtain wall away from the building, a perimeter sealing plate fixedly installed at the edges of the inner and outer curtain walls near each other for sealing purposes, an air inlet at the bottom of the outer curtain wall, and an air outlet at the top of the outer curtain wall. An adjustment device is provided between the inner and outer curtain walls at the air outlet, the adjustment device including a lifting plate that is longitudinally slidably installed on the perimeter sealing plate. The system includes a water collection trough fixedly installed at the bottom of the lifting plate and a drain pipe fixedly installed within the peripheral sealing plate. Several strip-shaped partitions are fixedly installed on the side of the lifting plate away from the air outlet, arranged in a linear array. A first filter screen is fixedly installed between adjacent strip partitions. A gap is formed in the lifting plate; when the lifting plate slides to its highest point, the position of the gap corresponds to the position of the first filter screen. The sliding distance of the lifting plate is equal to the width of the strip partitions. The drain pipe is connected to the internal storage space of the water collection trough when it slides to its lowest point. The adjustment device can automatically adjust itself based on rainwater, blocking the passage of air from the air outlet into the double-layer curtain wall and preventing rainwater from contaminating the exhaust duct.

[0009] Preferably, the adjusting device further includes receiving grooves located at both ends of the water collection tank on the peripheral sealing plate, a sliding rod slidably disposed in the receiving grooves near or away from the water collection tank, a rolling wheel rotatably mounted on the sliding rod, and an elastic element disposed in the receiving grooves. The water collection tank has two slots, upper and lower, with the distance between the two slots equal to the distance between adjacent strip partitions. The rolling wheel extends out of the receiving groove and matches the slot. The elastic element pushes the sliding rod, and the sliding rod drives the rolling wheel to abut against the slot at the upper position on the water collection tank, thereby achieving a stabilizing effect.

[0010] Preferably, the elastic element is a spring, with its two ends fixedly connected to the sliding rod and the inner wall of the receiving groove, respectively. The spring can push the sliding rod, which in turn pushes the rolling wheel, making it easy for the rolling wheel to engage in the groove.

[0011] Preferably, a ventilated decorative top plate is fixedly installed between the inner curtain wall and the outer curtain wall at the lowest position of the strip partition. The ventilated decorative top plate blocks the adjustment device at the air outlet and serves a decorative purpose without affecting ventilation.

[0012] Preferably, a baffle is provided below the water collection tank. The baffle is fixedly installed on the outer curtain wall and the surrounding sealing plate. After the water collection tank drives the lifting plate to descend, the rolling wheel rolls into the slot below. At this time, the baffle supports the bottom of the water collection tank to prevent the water collection tank from descending further.

[0013] Preferably, a ventilated decorative base plate is bolted between the inner curtain wall and the outer curtain wall at the top of the air inlet. The ventilated decorative base plate functions the same as the ventilated decorative top plate, which can separate the space at the bottom of the double-layer ventilated curtain wall.

[0014] Preferably, a bottom filter frame is provided on the perimeter sealing plate at the bottom surface of the ventilated decorative base plate. A second filter screen is fixedly provided on the bottom filter frame near the ventilated decorative base plate and the air inlet. When external air enters the ventilated curtain wall, it needs to pass through the two second filters on the bottom filter frame, which can greatly block dust and debris in the air and keep the inside of the ventilated curtain wall clean.

[0015] (III) Beneficial Effects

[0016] This double-layer ventilated curtain wall structure is equipped with a water collection trough. Under the action of rainwater, the water collection trough causes the lifting plate to descend. The lifting plate and the strip partition work together to seal the air outlet channel, preventing rainwater from continuing to enter the space between the inner and outer curtain walls. The rainwater can be discharged from the air outlet through the drainage pipe.

[0017] This double-layer ventilated curtain wall structure uses slots in the perimeter sealing plates. Under normal conditions, the elastic element in the slot pushes the sliding rod, which drives the rolling wheel to press against the slot at the upper position on the water collection tank, thus providing stability. When rainwater enters, the upper and lower slots are close together. After the rolling wheel rolls out of the upper slot, it is pushed by the sliding rod and quickly rolls into the lower slot. At this time, the lifting plate and the strip partition together seal the channel inside the air outlet, and the rainwater is discharged through the drain pipe. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an adjustable ventilated curtain wall structure, as shown in the reference. Figures 1 to 5 The system includes an inner curtain wall 1 fixed to the exterior of the building near the building, an outer curtain wall 2 fixed to the side of the inner curtain wall 1 away from the building, a perimeter sealing plate 3 fixedly installed at the edges of the inner curtain wall 1 and the outer curtain wall 2 near each other to provide a sealing effect, an air inlet 21 at the bottom of the outer curtain wall 2, and an air outlet 22 at the top of the outer curtain wall 2. An adjustment device 4 is provided between the inner curtain wall 1 and the outer curtain wall 2 at the air outlet 22. The adjustment device 4 includes a lifting plate 41 that is longitudinally slidably installed on the perimeter sealing plate 3 and a water collection tank 42 fixedly installed at the bottom of the lifting plate 41. The peripheral sealing plate 3 has a drain pipe 43 fixedly installed inside it. Several strip partitions 5 are fixedly installed on the side of the lifting plate 41 away from the air outlet 22. The strip partitions 5 are arranged in a linear array. A first filter screen 51 is fixedly installed between adjacent strip partitions 5. A gap 411 is opened on the lifting plate 41. When the lifting plate 41 slides to the highest point, the position of the gap 411 corresponds to the position of the first filter screen 51. The sliding distance of the lifting plate 41 is equal to the width of the strip partitions 5. The drain pipe 43 is connected to the internal storage space of the water collection tank 42 when it slides to the lowest point.

[0028] During normal operation, the windows on the inner curtain wall 1 are opened, and the water collection trough 42 is pushed from below. The water collection trough 42 causes the lifting plate 41 to rise. The gap 411 on the lifting plate 41 coincides with the position of the first filter 51 between the strip partition 5. The inlet of the drain pipe 43, which is located within the peripheral sealing plate 3, is sealed by the side wall of the water collection trough 42. The adjusting device 4 is in the open state, and the ventilated curtain wall is in the ventilated state. When it rains heavily, rainwater seeps into the air outlet 22 under the guidance of the wind, and a large amount of rainwater falls into the water collection trough 42. The water collection tank 42 is weighted and descends under the influence of gravity, which in turn causes the lifting plate 41 to descend. The first filter 51 between the gap 411 on the lifting plate 41 and the strip partition 5 is misaligned. The rainwater in the water collection tank 42 is discharged to the outside of the outer curtain wall 2 through the exposed drain pipe 43. At this time, the adjusting device 4 is in the closed state, preventing rainwater from continuing to enter the space between the inner curtain wall 1 and the outer curtain wall 2 from the air outlet 22. When the owner returns home or finds that it is raining, they can wait until the rain stops and then push the water collection tank 42 upward to return it to its original position.

[0029] Furthermore, refer to Figures 3 to 4 The adjusting device 4 also includes receiving grooves 44 located at both ends of the water collection tank 42 on the peripheral sealing plate 3, a sliding rod 45 slidably disposed in the receiving groove 44 near or away from the water collection tank 42, a rolling wheel 46 rotatably mounted on the sliding rod 45, and an elastic element 47 disposed in the receiving groove 44. The water collection tank 42 is provided with two slots 48, the distance between the two slots 48 is equal to the distance between adjacent strip partitions 5, and the rolling wheel 46 extends out of the receiving groove 44 and matches the slot 48.

[0030] Under normal conditions, within the receiving trough 44, the elastic element 47 pushes the sliding rod 45, which in turn drives the rolling wheel 46 to press against the slot 48 at the upper position on the water collection trough 42, thus providing stability. When affected by rainwater, the water collection trough 42 descends due to gravity, and the rolling wheel 46 rolls out of the upper slot 48. Since the upper and lower slots 48 are close together, the rolling wheel 46 is pushed by the sliding rod 45 after rolling out of the upper slot 48 and quickly rolls into the lower slot 48. At this time, the lifting plate 41 and the strip partition 5 together seal the channel inside the air outlet 22, and the rainwater is discharged through the drain pipe 43.

[0031] Furthermore, refer to Figure 4 The elastic element 47 is a spring, with its two ends fixedly connected to the sliding rod 45 and the inner wall of the receiving groove 44, respectively. The spring can push the sliding rod 45, which in turn pushes the rolling wheel 46, making it easy for the rolling wheel 46 to be locked in the slot 48.

[0032] It is worth noting that, referring to Figure 5A ventilated decorative top plate 52 is fixedly installed between the inner curtain wall 1 and the outer curtain wall 2 at the position of the lowest strip partition 5. The ventilated decorative top plate 52 blocks the adjustment device 4 at the air outlet 22 and also serves a decorative purpose without affecting ventilation.

[0033] Furthermore, refer to Figure 5 A baffle 23 is provided below the water collection tank 42. The baffle 23 is fixedly installed on the outer curtain wall 2 and the surrounding sealing plate 3. After the water collection tank 42 drives the lifting plate 41 to descend, the rolling wheel 46 rolls into the slot 48 below. At this time, the baffle 23 supports the bottom of the water collection tank 42 to prevent the water collection tank 42 from continuing to descend.

[0034] Furthermore, refer to Figure 6 A ventilated decorative base plate 6 is bolted between the inner curtain wall 1 and the outer curtain wall 2 at the top of the air inlet 21. The ventilated decorative base plate 6 has the same function as the ventilated decorative top plate 52, which can separate the space at the bottom of the double-layer ventilated curtain wall.

[0035] It should be noted that, referring to Figures 6 to 7 A bottom filter frame 7 is provided on the perimeter sealing plate 3 at the bottom surface of the ventilation decorative base plate 6. A second filter screen 71 is fixedly installed on the bottom filter frame 7 on the side close to the ventilation decorative base plate 6 and the air inlet 21. When the outside air enters the ventilation curtain wall, it needs to pass through the two second filters 71 on the bottom filter frame 7, which can greatly block dust and debris in the air and keep the inside of the ventilation curtain wall clean.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
