Description

Technical Field

[0001] The present application relates to the technical field of curtain walls, and in particular to a double-layered breathing energy-saving curtain wall. Background Art

[0002] Breathing curtain wall, also known as ventilation curtain wall or double-layer unit curtain wall, is a new type of energy-saving curtain wall. By switching on and off the curtain wall ventilation equipment, air can enter or escape from the middle of the double-layer curtain wall, thus reducing the indoor air conditioning load.

[0003] In summer, the temperature in the ventilation channel in the middle of the double-layer curtain wall is very high. The exhaust and air inlet at the upper and lower ends of the ventilation channel can be opened. In the ventilation duct, due to the "hot chimney effect", airflow from the bottom to the top is generated. The airflow entering from the lower air inlet is ventilated in the double layer and discharged from the upper air outlet after heat exchange. This bottom-up airflow movement takes away the heat in the channel, reduces the outer surface temperature of the inner curtain wall, reduces the load of air conditioning and refrigeration, saves energy, and reduces energy consumption; in winter, the ventilation channel in the middle of the double-layer curtain wall rises in temperature due to sunlight, forming a "greenhouse effect". This is conducive to increasing the surface temperature of the inner curtain wall and reducing the operating costs of the building due to winter heating.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] like Figure 1 , Figure 2 As shown, the double-layer breathing energy-saving curtain wall includes an outer layer of glass 11, an inner layer of glass 12, a top plate 13, a bottom plate 14 and a frame. The outer layer of glass 11 and the inner layer of glass 12 are fixed on the frame at intervals. The frame can be made of aluminum alloy or stainless steel. The top plate 13 is fixed to the upper end of the outer layer of glass 11 and the upper end of the inner layer of glass 12. The bottom plate 14 is arranged at the lower end of the outer layer of glass 11 and the lower end of the inner layer of glass 12. The top plate 13 and the bottom plate 14 are also made of metal, such as stainless steel or aluminum alloy.

[0032] An inner cavity is formed between the outer glass 11, the inner glass 12, the top plate 13 and the bottom plate 14. The bottom plate 14 is provided with an air inlet connected to the inner cavity, and the top plate 13 is provided with an air outlet 131 connected to the inner cavity. Filters are provided at the air inlet and the air outlet 131.

[0033] like Figure 2 As shown, a venetian blind 2 is arranged in the inner cavity.

[0034] In this embodiment, the venetian blind 2 includes a bracket 21 and mounting shafts 23 corresponding to the movable leaves 22 one by one. The bracket 21 is fixed in the inner cavity, the mounting shafts 23 are rotatably arranged on the bracket 21 along the horizontal direction, and the movable leaves 22 are fixed on the mounting shafts 23 corresponding thereto.

[0035] like Figure 2 , Figure 3 As shown, the energy-saving curtain wall also includes a motor 3, which is connected to the movable leaf 22 through a transmission mechanism 4 to drive the movable leaf 22 to swing back and forth.

[0036] In this embodiment, the transmission mechanism 4 includes a rack 41, a cross bar 42, a vertical bar 43, a connecting rod 44 and a crank 45. There are two racks 41 and they are arranged at intervals. The two racks 41 are slidably arranged on the bracket 21 along the vertical direction. Both ends of the mounting shaft 23 are provided with driven gears 46 meshing with the racks 41. The cross bar 42 is arranged in the horizontal direction. The upper ends of the two racks 41 are connected to the cross bar 42. The lower end of the vertical bar 43 is vertically fixed to the cross bar 42. One end of the connecting rod 44 is hinged to the upper end of the vertical bar 43, and the other end of the connecting rod 44 is hinged to one end of the crank 45. The other end of the crank 45 is fixed to the output shaft 47 of the motor 3.

[0037] The output shaft 47 of the motor 3 rotates, driving the crank 45 to swing, driving the vertical rod 43 to reciprocate in the vertical direction through the connecting rod 44, and the vertical rod 43 drives the rack 41 to reciprocate in the vertical direction through the cross rod 42. The rack 41 reciprocates and drives the mounting shaft 23 to rotate reciprocatingly through the driven gear 46, so that the movable leaf 22 on the mounting shaft 23 swings reciprocatingly.

[0038] like Figure 2 , Figure 4 , Figure 5 As shown, the movable leaves 22 of the venetian blind 2 are provided with cleaning members capable of contacting the outer layer of glass 11 and the inner layer of glass 12 .

[0039] In this embodiment, the cleaning member includes an elastic bag 5 fixed on the movable leaf 22, the elastic bag 5 is provided with a bag 1 51, a bag 2 52 and a fixing plate 53, the bag 1 51 and the bag 2 52 are fixed on both sides of the fixing plate 53, wherein the bag 1 51 is provided with a water outlet 511, a water storage tank 6 is provided at the top plate 13, a water pump 61 is provided in the water storage tank 6, and the water pump 61 is connected to the bag 1 51 through a pipe 1 62. The water pump 61 supplies water to the bag 1 51 through a pipe 1 62, and while the bag 1 51 is propped up, the water in the bag 1 51 can be sprayed into the outer glass 11 and the inner glass 12 for cleaning.

[0040] In this embodiment, the water delivery pump 61 includes blades and a pump shaft, the blades are fixed on the pump shaft, and the motor 3 is connected to the pump shaft through a transmission mechanism 7.

[0041] Preferably, the transmission mechanism 27 includes a large gear 71 and a small gear 72. The large gear 71 is fixed to the output shaft 47 of the motor 3, and the small gear 72 is connected to the pump shaft. The motor 3 drives the pump shaft to rotate through the transmission mechanism 27 to operate the water pump 61. The swing of the movable blade 22 and the operation of the water pump 61 share a set of driving sources.

[0042] The design of the large gear 71 and the small gear 72 makes the rotation speed of the pump shaft greater than the rotation speed of the output shaft 47, thereby ensuring the power of the water delivery pump 61 and preventing the movable blade 22 from moving too fast.

[0043] like Figure 2 , Figure 4 , Figure 5 As shown, an air pump 8 is also provided at the top plate 13, and an air outlet end 1 of the air pump 8 is connected to a pipeline 1 62, and an electromagnetic valve 1 is provided at the air outlet end of the air pump 8. After the water delivery pump 61 has finished cleaning the outer layer of glass 11 and the inner layer of glass 12, the air pump 8 can be used to inflate the pipeline 1 62, so that the gas is ejected through the water outlet hole 511 of the bag 1 51, and the outer layer of glass 11 and the inner layer of glass 12 are blown dry.

[0044] Preferably, the second outlet end of the air pump 8 is provided with a second solenoid valve, and the second outlet end of the air pump 8 is connected to the second bag 52 of the elastic bag 5 through a second pipeline 81, and the outer surface of the second bag 52 is provided with a reflective layer 9.

[0045] When the weather is hot, the air pump 8 can be used to inflate the bag 2 52 to expand the bag 2 52 , and the reflective layer 9 can reflect sunlight to the periphery of the building, thereby reducing the heat transfer into the building.

[0046] Preferably, the expanded lengths of bag 1 51 and bag 2 52 are equal, and they can contact the outer glass 11 and the inner glass 12. At the same time, when bag 1 51 and bag 2 52 are in a vertical state, they can contact bag 1 51 and bag 2 52 on adjacent movable leaves 22, so that the outer half of the inner cavity is isolated from the inner half, and the air inlet and outlet 131 are connected to the outer half of the inner cavity, thereby improving the thermal insulation effect and reducing the heat transfer from the building to the outside.

[0047] There are two types of movable leaves 22 and mounting shafts 23, one is an integrated type, and the other is a split type. When the split structure is adopted, the movable leaf 22 includes a plurality of cotyledons 221 distributed along the axial direction of the mounting shaft 23, and the mounting shaft 23 includes a semi-shaft 231 connected to each cotyledon 221, and each cotyledon 221 has a semi-shaft 231 at both ends. Pipeline 1 62 and pipeline 2 81 are opened on the semi-shaft 231, and a boss is opened on one of the semi-shafts 231, and a groove is opened on the other semi-shaft 231. The boss on one of the semi-shafts 231 of one cotyledon 221 can be snapped with the groove of the semi-shaft 231 on the adjacent cotyledon 221, and a mounting groove is opened on the end face of the cotyledon 221. The elastic bag 5 can be retracted into the mounting groove when it is in a contracted state, and the retraction action can be achieved by suction by the air pump 8.

[0048] The working principle of this embodiment is as follows: when dust appears on the outer glass 11 or the inner glass 12, the motor 3 drives the movable leaves 22 of the venetian blind 2 to swing through the transmission mechanism 4, so that the cleaning parts on the movable leaves 22 contact the outer glass 11 and the inner glass 12, and the dust on the outer glass 11 and the inner glass 12 is removed. At the same time, the water pump 61 supplies water to the bag 51 through the pipeline 62. While the bag 51 is propped up, the water in the bag 51 can be sprayed into the outer glass 11 and the inner glass 12 for cleaning. Finally, the air pump 8 is used to inflate the pipeline 62, so that the gas is sprayed out through the water outlet 511 of the bag 51 to dry the outer glass 11 and the inner glass 12.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
