Description

Technical Field

[0001] This invention belongs to the field of curtain wall technology, specifically relating to a double-layer curtain wall with automatic cleaning and ventilation. Background Technology

[0002] Currently, with people's increasing demands for the aesthetics and functionality of building appearances, building glass curtain walls are widely used in building decoration due to their excellent appearance, good lighting and energy-saving effects, as well as their fast construction speed, light structural weight and easy maintenance.

[0003] For example, in the Chinese invention patent CN109083316B entitled "A Double-Layer Curtain Wall," it includes columns installed on the main building structure and beams installed on the columns, as well as an inner panel and an outer panel. The inner panel is sealed to the columns and beams, and the outer panel is connected to the columns and beams. The outer panel is a decorative panel. Although the above-mentioned prior art can achieve heat preservation in winter and heat insulation in summer, reduce the energy consumption of air conditioning to control indoor temperature, and is energy-saving and environmentally friendly, the presence of dust in the air causes it to adhere to the inner side of the inner and outer glass when passing between them, making it inconvenient to clean. After long-term use, it will affect the light transmission effect of the curtain wall. Therefore, there is a need for a double-layer curtain wall with automatic cleaning and ventilation. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and rationally designed double-layer curtain wall with automatic cleaning and ventilation in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A double-layer curtain wall with automatic cleaning and ventilation includes a lower frame and an upper frame. Several mounting columns are vertically fixed to the outer sides of both the lower and upper frames. Tempered glass is installed between adjacent mounting columns. An air inlet is provided on the outer side of the lower frame, and several strip-shaped holes are provided on the inner side of the lower frame. Several first through holes are provided on the upper side of the lower frame, and an air outlet is provided on the outer side of the upper frame. Several second through holes are provided on the lower side of the upper frame. Several uprights are vertically fixed between the lower and upper frames. Guide sleeves are fixed to the inner sides of each of the mounting columns. Guide rods are slidably arranged between adjacent guide sleeves. A rubber scraper strip that adheres to the inner side of the tempered glass is fixed to one side of each guide rod, and a wind-facing plate is fixed to the other side of the guide rod. A clamping mechanism connected to the uprights is connected to one side of each of the plastering components.

[0007] As a further optimization of the present invention, the clamping mechanism includes a fixed base fixedly disposed on one side of the column, a sliding sleeve rotatably disposed on the lower side of the fixed base, a clamping spring fixedly disposed on the inner side of the sliding sleeve, a sliding rod fixedly disposed at one end of the clamping spring and slidingly penetrating the sliding sleeve, and the lower end of the sliding rod being rotatably connected to the guide rod.

[0008] As a further optimization of the present invention, a water storage mechanism that cooperates with a rubber scraper is provided between several of the mounting columns, and an exhaust mechanism that cooperates with several strip holes is provided on the inner side of the lower frame.

[0009] As a further optimization of the present invention, the water storage mechanism includes a horizontal pipe fixedly disposed between the mounting columns, a strip of sponge being fixedly disposed through the lower side of the horizontal pipe, a branch pipe fixedly connected to one end of the horizontal pipe and fixedly connected to the mounting column, and a main pipe fixedly connected to one end of the branch pipe.

[0010] As a further optimization of the present invention, the exhaust mechanism includes several fixed plates fixedly disposed inside the lower frame, a rotating rod rotatably passing through the middle of the fixed plates, a blade that mates with a strip hole fixedly disposed at one end of the rotating rod, a driven synchronous pulley fixedly disposed at the other end of the rotating rod, a servo motor fixedly disposed inside the lower frame, a main synchronous pulley fixedly disposed at the output end of the servo motor, and a synchronous belt meshing with the outer sides of the main synchronous pulley and the driven synchronous pulleys.

[0011] As a further optimization of the present invention, a first blocking mechanism that cooperates with the air inlet is provided on one side of the lower frame, and a second blocking mechanism that cooperates with the air outlet is provided on one side of the upper frame.

[0012] As a further optimization of the present invention, the first blocking mechanism includes a first baffle that is fixedly mounted on one side of the lower frame by screws and cooperates with the air inlet. The first baffle has a plurality of air inlet holes communicating with the air inlet, and a plurality of shielding plates that are rotatably disposed on the inner side of the first baffle and seal with the air inlet holes.

[0013] As a further optimization of the present invention, the second blocking mechanism includes a second baffle that is fixedly mounted on one side of the upper frame by screws and cooperates with the air outlet. The second baffle has a plurality of air outlet holes that communicate with the air outlet.

[0014] As a further optimization of the present invention, a plurality of screw holes are provided on one side of the lower frame, and two rows of mounting holes located on both sides of the tempered glass are provided on each of the mounting columns, and a positioning pin that mates with the mounting holes is provided on each of the mounting columns.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. In this invention, when wind from the outside of the curtain wall enters the lower frame through the air inlet, it passes through the first through-hole on the upper side of the lower frame between the two tempered glass panes. The wind blows the wind-facing plate, causing it to rise. This, in turn, raises the guide rod and rubber scraper on one side of the wind-facing plate, allowing the rubber scraper to slide on the inside of the tempered glass, thus scraping away dust and automatically cleaning the dust inside the tempered glass. As the rubber scraper rises, it squeezes the sliding rod into the inside of the sliding sleeve, compressing the tension spring inside the sliding sleeve. This compression of the tension spring, through its elasticity, forces the sliding rod and guide rod together, making the rubber scraper on the guide rod side slide more tightly against the inside of the tempered glass, improving the dust removal effect. When the rubber scraper reaches its highest point, it squeezes the strip-shaped sponge on the lower side of the horizontal tube, causing the cleaning water inside the strip-shaped sponge to be squeezed onto the inside of the tempered glass, further improving the dust cleaning effect.

[0017] 2. In this invention, the main synchronous pulley is driven to rotate by a servo motor, which in turn drives multiple slave synchronous pulleys to rotate via a synchronous belt. This causes the rotating rods at the center of the slave synchronous pulleys to rotate, which in turn drives multiple blades at the other end of the rotating rods to rotate. This allows indoor air to be drawn into the inner side of the lower frame and then flows into the upper frame through the space between the two tempered glass panes. The air is then discharged from the air outlet on one side of the upper frame, allowing the indoor air to convect with the outside air and thus automatically regulating the indoor temperature.

[0034] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Implementation, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 、 Figure 7 、 Figure 8 、 Figure 11 、 Figure 12 、 Figure 15As shown, a double-layered curtain wall with automatic cleaning and ventilation includes a lower frame 1 and an upper frame 2. Both the lower frame 1 and the upper frame 2 adopt a square hollow steel tube structure. One side of the lower frame 1 and the upper frame 2 is located on the outside, and the other side is located indoors. Several mounting columns 3 are vertically fixed on the outer side 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 set on one side of the lower frame 1 and the upper frame 2, and three mounting columns 3 are set 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. Tempered glass 14 is installed between two adjacent mounting columns 3. Two rows of mounting holes 301 are opened on each of the mounting columns 3 located on both sides of the tempered glass 14. Each of the mounting columns 3 is provided with mounting holes 301 for mounting. The positioning pins 302 that mate with the mounting holes 301 are used to position the tempered glass 14 between two adjacent mounting posts 3 via a sealing strip (not shown in the figure). Then, the positioning pins 302 are 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, thus limiting the tempered glass 14 between the two adjacent mounting posts 3 and preventing it from falling off. An air inlet 101 is provided on the outer side of the lower frame 1, and several strip-shaped holes 103 are provided on the inner side of the lower frame 1. These strip-shaped holes 103 facilitate the exchange of indoor and outdoor air, allowing for temperature regulation. Several screw holes 104 are provided on one side of the lower frame 1. The screw holes 104 are positioned within the strip-shaped holes. When ventilation is not required, the sealing plate (not shown in the figure) can be fixed to one side of the strip hole 103 to seal the strip hole 103, thus isolating the interior from the outside. This also prevents dust from the outside air from entering the interior when there is a strong wind, improving the cleanliness of the interior. Several first through holes 102 are provided on the upper side of the lower frame 1, through which air entering the inside of the lower frame 1 can enter between the two tempered glass panes 14. A first blocking mechanism 11 that cooperates with the air inlet 101 is provided on one side of the lower frame 1. The first blocking mechanism 11 includes a first baffle 1101 that is fixed to one side of the lower frame 1 by screws and cooperates with the air inlet 101. The first baffle 1101 has several air inlet holes 1102 that communicate with the air inlet 101. The air inlet holes 1102 can block large debris in the air, preventing large debris from being blown up by the wind and entering the interior of the lower frame 1, thus preventing blockage of the first through hole 102 and entry into the room. The inner side of the first baffle 1101 is rotatably provided with several baffles 1103 that seal with the air inlet holes 1102. The upper side of the baffles 1103 is rotatably connected to the first baffle 1101. In a natural state (i.e., in a windless state), the baffles 1103 are in a vertical state, which blocks the air inlet holes 1102 on the first baffle 1101, preventing the air in the lower frame 1 from flowing out of the air inlet holes 1102 in the opposite direction.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 13 As shown, an air outlet 201 is provided on the outer side of the upper frame 2, and several second through holes 202 are provided on the lower side of the upper frame 2. Air between the two tempered glass panes 14 can enter the interior of the upper frame 2 through the second through holes 202 and then exit from the air outlet 201, improving airflow and preventing wind from directly impacting the curtain wall and affecting its safety. 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 fixed to one side of the upper frame 2 by screws and cooperating with the air outlet 201. Several air outlet holes 1202 communicating with the air outlet 201 are provided on the second baffle 1201. Several columns 4 are vertically fixed between the lower frame 1 and the upper frame 2. Guide sleeves 10 are fixedly provided on the inner side of each of the several mounting columns 3. A guide rod 6 is slidably arranged between two adjacent guide sleeves 10 laterally. A rubber scraper 8 is fixedly installed, with one side of the rubber scraper 8 adhering to the inner side of the tempered glass 14. The rubber scraper 8 can scrape away dust from the inner side of the tempered glass 14, and the guide rod 6 can also support the tempered glass 14 to prevent large areas of the tempered glass 14 from deforming under the action of wind, thus preventing the safety of the tempered glass 14 from being affected. A windproof plate 7 is fixedly installed on the other side of the guide rod 6. The windproof plate 7 mostly covers several second through holes 202, so that the wind blowing out of the several second through holes 202 can drive the windproof plate 7 to rise. The windproof plate 7 is tilted so that the wind blowing out of the first through hole 102 on the upper side of the lower frame 1 can blow directly onto the windproof plate 7, so that the windproof plate 7 can move with the wind, which can drive the guide rod 6 and the rubber scraper 8 on one side of the windproof plate 7 to rise vertically, so that the rubber scraper 8 can scrape away the dust adhering to the inner side of the tempered glass 14.

[0037] like Figure 1 , Figure 2 , Figure 10As shown, a clamping mechanism 5 connected to the column 4 is connected to one side of several guide rods 6. The clamping mechanism 5 includes a fixed base 501 fixedly installed on one side of the column 4. A sliding sleeve 502 is rotatably installed on the lower side of the fixed base 501. A clamping spring 503 is fixedly installed on the inner side of the sliding sleeve 502. A sliding rod 504 that slides through the sliding sleeve 502 is fixedly installed at one end of the clamping spring 503. The lower end of the sliding rod 504 is rotatably connected to the guide rod 6. In its natural state, the sliding rod 504 is tilted downward. In use, when the air blown out of the first through hole 102 on the upper side of the lower frame 1 blows directly onto the windproof plate 7, it will cause the windproof plate 7 to rise, thereby causing the guide rod 6 on one side of the windproof plate 7 to rise under the action of the guide sleeve 10. This allows the sliding rod 504 on one side of the guide rod 6 to slide into the inner side of the sliding sleeve 502, thereby compressing the sliding sleeve 502. The inner clamping spring 503, when compressed, causes the sliding rod 504 and guide rod 6 to be pressed against each other by the elastic force of the clamping spring 503. This makes the rubber scraper 8 on one side of the guide rod 6 slide more tightly against the inner side of the tempered glass 14, improving the dust removal effect. It also supports the tempered glass 14, preventing deformation of the tempered glass 14 in windy weather and affecting its safety. Since the wind speed is constantly changing, when the wind speed is low, the elastic force of the clamping spring 503 will press the sliding rod 504 out of the sliding sleeve 502, causing the guide rod 6 to descend on one side of the guide sleeve 10. This allows the rubber scraper 8 on one side of the guide rod 6 to scrape the dust downwards. The reciprocating motion of the rubber scraper 8 improves the cleaning effect on the tempered glass.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 9 , Figure 10As shown, a water storage mechanism 9, which cooperates with a rubber scraper 8, is provided between several mounting columns 3. The water storage mechanism 9 includes a horizontal pipe 901 fixedly arranged between the mounting columns 3. A strip-shaped sponge 902 is fixedly arranged through the lower side of the horizontal pipe 901. One end of the horizontal pipe 901 is fixedly connected to a branch pipe 903 fixedly connected to the mounting column 3. One end of the branch pipe 903 is fixedly connected to a main pipe 904. One end of the main pipe 904 is connected to a water tank (not shown in the figure). The water tank is located at the top of 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 can enter the branch pipe 903 through the main pipe 904, and then enter the interior of the horizontal pipe 901 through the branch pipe 903. This allows cleaning water to enter the interior of the strip sponge 902. A drainage hole (not shown in the figure) is provided at the bottom of the lower frame 1 to facilitate the drainage of cleaning water. When the rubber squeegee 8 is raised to the top, it will squeeze the strip sponge 902 under the horizontal tube 901, causing the cleaning water inside the strip sponge 902 to be squeezed to the inside of the tempered glass 14. This allows the rubber squeegee 8 to work in conjunction with the cleaning water to further improve the dust cleaning effect. In addition, the cleaning water absorbed inside the strip sponge 902 can evaporate between the two layers of tempered glass during hot summer days, preventing the high temperature from the outside from being transmitted to the room and improving the coolness of the room.

[0039] like Figure 5 , Figure 6 , Figure 14 , Figure 15As shown, the inner side of the lower frame 1 is provided with an exhaust mechanism 13 that mates with several slotted holes 103. The exhaust mechanism 13 includes several fixed plates 1301 fixedly disposed on the inner side of the lower frame 1. A rotating rod 1302 rotatably passes through the middle of the fixed plates 1301. One end of the rotating rod 1302 is fixedly provided with a blade 1304 that mates with the slotted holes 103. The other end of the rotating rod 1302 is fixedly provided with a synchronous pulley 1303. A servo motor 1306 is fixedly disposed on the inner side of the lower frame 1. The servo motor 1306 can rotate in both directions. When the servo motor 1306 rotates forward, it drives the blade 1304 to exhaust air. When the servo motor 1306 rotates in reverse, it drives the blade 1304 to draw in air. During the drawing process, the specific process is as follows: outside air is drawn into the interior of the lower frame 1 through the air outlet 201 and 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). 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 pulley 1307 is fixedly installed at the output end. The main synchronous pulley 1307 and several slave synchronous pulleys 1303 are meshed with a synchronous belt 1305 on their outer sides. When the temperature sensor detects that the indoor temperature is higher than the outdoor temperature, the controller controls the servo motor 1306 to work, which in turn drives the main synchronous pulley 1307 at its output end to rotate. This drives the synchronous belt 1305 on the outer side of the main synchronous pulley 1307 to rotate, which in turn drives the multiple slave synchronous pulleys 1303 to rotate. This causes the rotating rod 1302 at the center of the multiple slave synchronous pulleys 1303 to rotate, thus driving the synchronous belt 1305 to rotate. The rotation of multiple blades 1304 at the other end of the rotating rod 1302 allows indoor air to be drawn into the inner side of the lower frame 1, and then flows into the upper frame 2 through the space between the two tempered glass panes 14, and is then discharged from the air outlet 201 on one side of the upper frame 2. This allows the indoor air to convect with the outside air, thereby automatically regulating the indoor temperature. During the exhaust process, the air intake plate 7 is also raised, causing the guide rod 6 and rubber scraper 8 on one side of the air intake plate 7 to rise vertically, making it easier for the rubber scraper 8 to remove dust adhering to the inner side of the tempered glass pane 14.

[0040] It should be noted that in use, this type of self-cleaning and ventilated double-layer curtain wall, when it is windy, the wind will blow the first baffle 1101 on one side of the lower frame 1, causing the shielding plate 1103 on the inner side of the first baffle 1101 to open, allowing air to enter the inner side of the lower frame 1 through the first through hole 102, and then blow into the space between the two tempered glass panes 14 through the first through hole 102 on the upper side of the lower frame 1. When it enters, the wind will blow directly onto the wind-facing plate 7, causing the wind-facing plate 7 to rise with the wind, thereby raising the guide rod 6 on one side of the wind-facing plate 7 to the inner side of the guide sleeve 10. During the raising process, the guide rod 6 will cause the rubber scraper 8 on one side of the guide rod 6 to adhere to the inner side of the tempered glass 14 and rise, thereby scraping away the dust adhering to the inner side of the tempered glass 14. In addition, the guide rod 6 also... This causes the slide rod 504 to slide into the inner side of the slide sleeve 502, thereby compressing the tension spring 503 inside the slide sleeve 502. The compression of the tension spring 503 allows the spring force to press the slide rod 504 and the guide rod 6 in the opposite direction, making the rubber scraper 8 on one side of the guide rod 6 slide more tightly against the inner side of the tempered glass 14, improving the dust removal effect. It also provides support for the tempered glass 14, preventing deformation of the tempered glass 14 in windy weather and affecting its safety. When the rubber scraper 8 is raised to the top, it will squeeze the strip sponge 902 under the horizontal tube 901, causing the cleaning water inside the strip sponge 902 to be squeezed onto the inner side of the tempered glass 14. This combination of the rubber scraper 8 and the cleaning water further improves the dust removal effect.

[0041] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
