DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig.11 , Fig.12 , Fig.15As shown, a double-layer curtain wall with automatic cleaning and ventilation includes a lower frame 1 and an upper frame 2. The lower frame 1 and the upper frame 2 both adopt a square hollow steel tube structure. One side of the lower frame 1 and the upper frame 2 is arranged outside, and the other side is arranged indoors. A plurality of mounting columns 3 are vertically fixedly arranged on the outer sides of the lower frame 1 and the upper frame 2. This embodiment only shows six mounting columns 3, that is, three mounting columns 3 are arranged on one side of the lower frame 1 and the upper frame 2, and three mounting columns 3 are arranged on the other side of the lower frame 1 and the upper frame 2. The specific number can be flexibly selected according to the size of the curtain wall. A tempered glass 14 is installed between two adjacent mounting columns 3. Two rows of mounting holes 301 located on both sides of the tempered glass 14 are opened on the plurality of mounting columns 3. The positioning pin 302 matched with the mounting hole 301 is used to set the tempered glass 14 between two adjacent mounting columns 3 through a sealing strip (not shown in the figure), and then the positioning pins 302 are respectively installed in the mounting holes 301 on both sides of the tempered glass 14. The positioning pins 302 abut against the sealing strips on both sides of the tempered glass 14, so that the tempered glass 14 can be limited between the two adjacent mounting columns 3 to prevent the tempered glass 14 from falling off. An air inlet 101 is provided on the outer side of the lower frame 1, and a plurality of strip holes 103 are provided on the inner side of the lower frame 1. The strip holes 103 facilitate the exchange of indoor air with external air, so as to adjust the indoor temperature. A plurality of screw holes 104 are provided on one side of the lower frame 1, and the screw holes 104 are provided on the strip Around the strip hole 103, when ventilation is not needed, it is only necessary to fix a blocking plate (not shown in the figure) on one side of the strip hole 103 to seal the strip hole 103, so that the room can be isolated from the outside, and dust in the outside air can be prevented from entering the room when there is a strong wind outside, thereby improving the cleanliness of the room. A plurality of first through holes 102 are provided on the upper side of the lower frame 1, and the wind entering the inner side of the lower frame 1 can enter between the two tempered glasses 14 through the first through holes 102. A first blocking mechanism 11 cooperating with the air inlet 101 is provided on one side of the lower frame 1, and the first blocking mechanism 11 includes a first baffle 1101 fixedly arranged on one side of the lower frame 1 by screws and cooperating with the air inlet 101. The first baffle plate 1101 is provided with a plurality of air inlet holes 1102 connected with the air inlet port 101. The air inlet holes 1102 can block large debris in the air to prevent the large debris from flying up due to wind, and allowing the large debris to enter the interior of the lower frame 1 to prevent the first through hole 102 from being blocked and entering the room. A plurality of shielding plates 1103 that are sealed with the air inlet holes 1102 are rotatably provided on the inner side of the first baffle plate 1101. The upper sides of the plurality of shielding plates 1103 are rotatably connected with the first baffle plate 1101. In a natural state (i.e., a windless state), the shielding plates 1103 are in a vertical state, so that the air inlet holes 1102 on the first baffle plate 1101 are blocked to prevent the air in the lower frame 1 from flowing out of the air inlet holes 1102 in the opposite direction.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.13 As shown, an air outlet 201 is provided on the outer side of the upper frame 2, and a plurality of second through holes 202 are provided on the lower side of the upper frame 2. The air between the two tempered glasses 14 can enter the interior of the upper frame 2 through the second through holes 202, and then be discharged from the air outlet 201, thereby improving the fluidity of the air and preventing the wind from directly hitting the curtain wall and affecting the safety of the curtain wall. A second blocking mechanism 12 cooperating with the air outlet 201 is provided on one side of the upper frame 2. The second blocking mechanism 12 includes a second baffle 1201 fixedly provided on one side of the upper frame 2 by screws and cooperating with the air outlet 201. A plurality of air outlet holes 1202 communicating with the air outlet 201 are provided on the second baffle 1201. A plurality of columns 4 are vertically fixedly provided between the lower frame 1 and the upper frame 2. A guide sleeve 10 is fixedly provided on the inner side of a plurality of mounting columns 3. A guide rod 6 is slidably provided between two adjacent guide sleeves 10 in the horizontal direction. One side of the guide rod 6 A rubber scraper 8 is fixedly arranged, and one side of the rubber scraper 8 is in contact with the inner side of the tempered glass 14. On the one hand, the rubber scraper 8 can be used to scrape off the dust on the inner side of the tempered glass 14, and on the other hand, the guide rod 6 can also play the role of supporting the tempered glass 14, so as to avoid deformation of a large area of ​​the tempered glass 14 under the action of wind force, and prevent the safety of the tempered glass 14 from being affected. A windward plate 7 is fixedly arranged on the other side of the guide rod 6, and most of the windward plate 7 covers a plurality of second through holes 202, so that the wind blown out through the plurality of second through holes 202 drives the windward plate 7 to rise. The windward plate 7 is tilted, so that the wind blown out from the first through holes 102 on the upper side of the lower frame 1 is blown onto the windward plate 7 directly, so that the windward plate 7 can move with the wind, so as to drive the guide rod 6 and the rubber scraper 8 on one side of the windward plate 7 to rise vertically, so that the rubber scraper 8 can scrape off the dust adhering to the inner side of the tempered glass 14.

[0021] like Figure 1 , Figure 2 , Fig.10As shown, one side of the guide rods 6 is connected to a tightening mechanism 5 connected to the column 4, and the tightening mechanism 5 includes a fixed base 501 fixedly arranged on one side of the column 4, a sliding sleeve 502 is rotatably arranged on the lower side of the fixed base 501, and a tightening spring 503 is fixedly arranged on the inner side of the sliding sleeve 502, and one end of the tightening spring 503 is fixedly provided with a sliding rod 504 that slides through the sliding sleeve 502, and the lower end of the sliding rod 504 is rotatably connected to the guide rod 6. In a natural state, the sliding rod 504 is inclined downward. When in use, when the wind blown out of the first through hole 102 on the upper side of the lower frame 1 blows directly onto the windward plate 7, it will drive the windward plate 7 to rise, and then drive the guide rod 6 on one side of the windward plate 7 to rise under the action of the guide sleeve 10, so that the sliding rod 504 on one side of the guide rod 6 can slide into the inner side of the sliding sleeve 502, thereby compressing the sliding sleeve 5 The tensioning spring 503 on the inner side of 02 compresses the tensioning spring 503, and the sliding rod 504 and the guide rod 6 can be squeezed in the opposite direction by the elastic force of the tensioning spring 503, so that the rubber scraper 8 on one side of the guide rod 6 can fit more closely and slide on the inner side of the tempered glass 14, thereby improving the dust scraping effect, and can also play a supporting role for the tempered glass 14, avoiding the deformation of the tempered glass 14 in windy weather, thereby affecting the safety of the tempered glass 14, and because the wind speed changes all the time, when the wind speed is relatively small, the elastic force of the tensioning spring 503 will press the sliding rod 504 to slide out of the sliding sleeve 502, thereby causing the guide rod 6 to descend on one side of the guide sleeve 10, so that the rubber scraper 8 on one side of the guide rod 6 can scrape the dust downward, and the rubber scraper 8 can be lifted and lowered reciprocally, thereby improving the cleaning effect of the tempered glass.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Fig. 9 , Fig.10As shown, a water storage mechanism 9 cooperating with the rubber scraper 8 is arranged between the plurality of mounting columns 3, and the water storage mechanism 9 includes a transverse tube 901 fixedly arranged between the mounting columns 3, a strip sponge 902 is fixedly arranged through the lower side of the transverse tube 901, one end of the transverse tube 901 is fixedly connected with a branch pipe 903 fixedly connected to the mounting column 3, one end of the branch pipe 903 is fixedly connected with a main pipe 904, one end of the main pipe 904 is connected with a water tank (not shown in the figure), and the water tank is arranged above the room, that is, the height of the water tank is higher than the height of the main pipe 904, so that the clean water in the water tank enters the branch pipe 903 through the main pipe 904, and then enters the interior of the transverse tube 901 through the branch pipe 903 , so that the cleaning water enters the interior of the strip sponge 902. A drainage hole (not shown in the figure) is opened at the bottom of the lower frame 1 to facilitate the discharge of the cleaning water. When the rubber scraper 8 is raised to the top, the rubber scraper 8 will squeeze the strip sponge 902 on the lower side of the horizontal tube 901, so that the clean water inside the strip sponge 902 is squeezed to the inner side of the tempered glass 14, so that the rubber scraper 8 cooperates with the clean water to further improve the dust cleaning effect. The clean water adsorbed inside the strip sponge 902 can also evaporate between the two layers of tempered glass in the high temperature in summer, thereby avoiding the high temperature outside from being transmitted to the room, thereby improving the coolness of the room.

[0023] like Figure 5 , Figure 6 , Fig.14 , Fig.15As shown, the inner side of the lower frame 1 is provided with an exhaust mechanism 13 that cooperates with the plurality of strip holes 103. The exhaust mechanism 13 includes a plurality of fixed plates 1301 fixedly provided on the inner side of the lower frame 1. A rotating rod 1302 is passed through the middle of the plurality of fixed plates 1301. A blade 1304 that cooperates with the strip holes 103 is fixedly provided at one end of the plurality of rotating rods 1302. A slave synchronous wheel 1303 is fixedly provided at the other end of the plurality of rotating rods 1302. A servo motor 1306 is fixedly provided on the inner side of the lower frame 1. The servo motor 1306 can rotate forward and reverse. When the servo motor 1306 rotates forward and reversely, the servo motor 1306 rotates forward and reversely. When the servo motor 1306 rotates forward, it drives the blades 1304 to exhaust air. When the servo motor 1306 rotates reversely, it drives the blades 1304 to extract air. When in the exhaust process, the specific process is: the outside air is sucked into the interior of the lower frame 1 through the air outlet 201 and the air inlet 301 on one side of the lower frame 1 and the upper frame 2, and finally blown into the room through the strip hole 103 on one side of the lower frame 1. The servo motor 1306 is electrically connected to a controller (not shown in the figure), and the controller is connected to the indoor temperature sensor (not shown in the figure) through a wire. The output of the servo motor 1306 A main synchronous wheel 1307 is fixedly provided at the output end, and a synchronous belt 1305 is meshed with the outer sides of the main synchronous wheel 1307 and a plurality of slave synchronous wheels 1303. When the temperature sensor detects that the indoor temperature is higher than the outdoor temperature, the servo motor 1306 is controlled by the controller to work, thereby driving the main synchronous wheel 1307 at the output end to rotate, and driving the synchronous belt 1305 on the outer side of the main synchronous wheel 1307 to rotate, and then the plurality of slave synchronous wheels 1303 can be driven to rotate through the synchronous belt 1305, so that the rotating rod 1302 in the center of the plurality of slave synchronous wheels 1303 rotates, and the belt The multiple blades 1304 at the other end of the rotating rod 1302 rotate, so that the indoor air can be drawn into the inner side of the lower frame 1, and then flow into the upper frame 2 through the two tempered glasses 14, and then be discharged from the air outlet 201 on one side of the upper frame 2, so that the indoor air and the outside air can be convected, thereby automatically adjusting the indoor temperature. In the process of exhausting air, the windward plate 7 can also be driven to rise, so that the guide rod 6 and the rubber scraper 8 on one side of the windward plate 7 can be vertically raised, so that the rubber scraper 8 can scrape off the dust adhering to the inner side of the tempered glass 14.

[0024] It should be noted that, when the double-layer curtain wall with automatic cleaning and ventilation is in use, when it is windy outside, the wind will blow the first baffle 1101 on one side of the lower frame 1, so that the shielding plate 1103 on the inner side of the first baffle 1101 is opened, and the wind can enter the inner side of the lower frame 1 through the first through hole 102, and then blow into between the two tempered glasses 14 through the first through hole 102 on the upper side of the lower frame 1. When entering, the wind will blow directly onto the windward plate 7, so that the windward plate 7 can rise with the wind, thereby driving the guide rod 6 on one side of the windward plate 7 to rise to the inner side of the guide sleeve 10. In the process of the guide rod 6 rising, it will drive the rubber scraper 8 on one side of the guide rod 6 to fit and rise on the inner side of the tempered glass 14, thereby scraping off the dust adhering to the inner side of the tempered glass 14, and the guide rod 6 will also The sliding rod 504 will be driven to slide into the inner side of the sliding sleeve 502, thereby compressing the tensioning spring 503 on the inner side of the sliding sleeve 502, so that the tensioning spring 503 is compressed, and the sliding rod 504 and the guide rod 6 can be reversely squeezed by the elastic force of the tensioning spring 503, so that the rubber scraper 8 on one side of the guide rod 6 can slide more closely on the inner side of the tempered glass 14, thereby improving the dust scraping effect, and can also play a supporting role for the tempered glass 14, avoiding the deformation of the tempered glass 14 in windy weather, thereby affecting the safety of the tempered glass 14, and when the rubber scraper 8 is raised to the top, the rubber scraper 8 will squeeze the strip sponge 902 on the lower side of the cross tube 901, so that the clean water on the inner side of the strip sponge 902 is squeezed to the inner side of the tempered glass 14, so that the rubber scraper 8 cooperates with the clean water to further improve the dust cleaning effect.

[0025] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
