Description

Technical Field

[0001] The present application relates to the technical field of building ventilation equipment installation, and in particular to an improved unit curtain wall ventilation structure. Background Art

[0002] With the development of social economy, the process of urbanization is accelerating, and high-rise buildings are increasing. As an important component of modern high-rise buildings, building curtain walls play an important role in realizing the functionality and aesthetics of buildings.

[0003] In order to improve the air quality inside the building, the traditional approach is to install ventilators on the aluminum alloy beams in the curtain wall frame structure. This method achieves ventilation by deploying ventilation devices in the space reserved by the beams.

[0004] The above traditional methods can meet the needs of indoor ventilation to a certain extent, but there are obvious limitations. On the one hand, since the ventilator is hidden in the beam, its volume is strictly limited, which directly affects the maximum exhaust volume of the ventilator, making the air circulation in the room poor and difficult to create a good living environment. On the other hand, since the vents are located in places with relatively harsh outdoor environments, they are prone to leakage due to rain erosion, which not only threatens the safety of the building, but also increases maintenance costs. At the same time, such an arrangement often has a negative impact on the appearance of the building, especially in the pursuit of a simple and modern design. Summary of the invention

[0005] In order to increase the ventilation volume of the unit curtain wall, the present application provides an improved unit curtain wall ventilation structure.

[0006] The improved unit curtain wall ventilation structure provided in this application adopts the following technical solution: An improved unit curtain wall ventilation structure comprises an upper curtain wall panel, a ventilation panel and a lower curtain wall panel, wherein the ventilation panel comprises a main frame and an axial flow fan arranged in the main frame, the main frame is connected between the upper and lower curtain wall panels, an air inlet duct and an air outlet duct are arranged in parallel in the main frame, and the air inlet duct is located directly below the air outlet duct, one axial flow fan is installed in the air inlet duct and the air outlet duct corresponding to the planned wind direction, ventilation louvers are arranged on the same vertical rotation side close to the outdoors in the air inlet duct and the air outlet duct, a driving assembly for driving the ventilation louvers to rotate is arranged on the main frame, a temperature and humidity sensor is also arranged on the side wall of the main frame facing the outdoors, the temperature and humidity sensor is electrically connected to the driving assembly, and a filter is arranged between the axial flow fan and the ventilation louver in the air inlet duct and the air outlet duct.

[0007] By adopting the above technical solution, when the ventilation system is turned on, the axial flow fan starts to operate, sucking in fresh air from the outside from the air inlet and transporting it to the room through the pipe, while discharging the dirty air in the room from the air outlet duct, forming an effective internal and external air exchange. In this process, the setting of the filter improves the air purification ability and ensures that the air entering the room is cleaner. The reasonable layout of the axial flow fan ensures the efficient operation of the ventilation system. The ventilation louvers and their drive components can automatically adjust the opening according to the changes in outdoor temperature and humidity, thereby reducing the risk of rainwater intrusion and enhancing the system's ability to adapt to different weather conditions. The improved unit curtain wall ventilation structure designs a central ventilation structure between the upper and lower unit curtain walls, so that the ventilator and the curtain wall structure are separated, and the size, structure and layout of the ventilator can be designed more freely, thereby significantly increasing the ventilation volume and optimizing the indoor and outdoor air exchange efficiency.

[0008] Optionally, the ventilation louver includes a plurality of rotating rods rotatably arranged on a main frame and blades sleeved on the rotating rods, a cavity is opened in the side wall of the main frame, and the ends of the plurality of rotating rods on the same side rotate and penetrate the side wall of the main frame and extend into the cavity, the driving assembly includes a worm wheel sleeved on the end of the rotating rod, a worm meshing with the worm wheel, and a servo motor driving the worm to rotate, the plurality of worm wheels are vertically distributed in the cavity on the same side, the worm is located on one side of the worm wheel and is vertically rotatably arranged in the cavity, and the worm and the plurality of worm wheels are meshed together.

[0009] By adopting the above technical solution, when the temperature and humidity sensor senses the change of outdoor temperature and humidity, it transmits the electrical signal to the servo motor. After receiving the signal, the servo motor drives the worm to rotate. The rotation of the worm drives the synchronous rotation of several worm wheels meshing with it, realizing the synchronous flipping of several blades, thereby automatically adjusting the opening of the ventilation shutter according to the change of outdoor temperature and humidity. This design makes the opening and closing of the ventilation shutter more stable and reliable, and improves the overall automation level and ventilation efficiency of the ventilation structure.

[0010] Optionally, each blade is provided with a stop plate on its side wall parallel to its own axial direction, and the two stop plates on the same blade are symmetrically arranged along the axial direction of the blade. When the ventilation louver is in a closed state, the surface of the ventilation louver facing the outdoor side is flat, and the opposite stop plates on two adjacent blades are arranged to abut against each other.

[0011] By adopting the above technical solution, when the ventilation louver is in a closed state, the surface of the ventilation louver facing the outdoors is flat, and the relative abutment plates on two adjacent blades are abutted against each other. Compared with the side walls of two adjacent blades fitting each other, the ventilation louver has higher sealing performance in the closed state, which can effectively prevent leakage caused by rainwater erosion, while improving the safety of the building and reducing maintenance costs.

[0012] Optionally, one of the abutment plates on each of the blades is provided with bristles made of flexible material along its length direction, and when the ventilation louver is in an open state, the bristles are arranged to abut against an adjacent filter screen.

[0013] By adopting the above technical solution, when the ventilation louvers automatically adjust the opening degree according to changes in outdoor temperature and humidity, the bristles scrape the surface of adjacent filters as the blades flip, which can effectively remove dust and impurities attached to the filters, reduce the possibility of filter blockage, and ensure the continuous and efficient operation of the ventilation system.

[0014] Optionally, the air inlet duct and the air outlet duct are both arranged to be inclined upward toward the room.

[0015] By adopting the above technical solution, the air inlet duct and the air outlet duct are both tilted upward toward the room, which can make the airflow entering the room smoother, reduce wind resistance, and improve ventilation efficiency. At the same time, the tilted setting also helps prevent rainwater from flowing into the room, thereby improving the waterproof performance of the overall structure.

[0016] Optionally, anti-blocking fences are slidably provided in the air inlet duct and the air outlet duct on the side of the filter screen away from the ventilation louver, and the anti-blocking fence includes a fence frame and an anti-blocking rod. The fence frame slides with the duct, the anti-blocking rods correspond to the mesh holes on the filter screen one by one, and the anti-blocking rods are distributed on the side walls of the fence frame facing the filter screen. When the ventilation louver is in a closed state, the anti-blocking rods are inserted into the mesh holes on the filter screen.

[0017] By adopting the above technical solution, the anti-blocking fence is slidably set in the air inlet duct and the air outlet duct, so that the anti-blocking rod passes through the corresponding mesh holes on the filter screen during the sliding process, thereby reducing the possibility of the mesh holes of the filter screen being blocked by dust and impurities, and further dredging the filter screen to improve air quality and equipment service life.

[0018] Optionally, the end of the rotating rod facing away from the worm gear extends into a cavity on the other side of the main frame, and a winding wheel is sleeved on the end of the rotating rod extending into the cavity, a guide rod is provided on the side wall of the anti-blocking fence close to the winding wheel, the end of the guide rod passes through the side wall of the main frame and extends to the cavity, and a pull rope is connected between the winding wheel and the end of the guide rod, and a guide through hole for the guide rod to pass through is opened on the main frame along the sliding direction of the anti-blocking fence, and the guide rod is slidably fitted with the guide through hole, and a fixing rod is provided on the inner side wall of the cavity on the main frame, the fixing rod is located on the end side of the guide through hole facing away from the winding wheel, and a tension spring is connected between the fixing rod and the end of the guide rod.

[0019] By adopting the above technical solution, when the ventilation louver rotates, the rotating rod drives the winding wheel to rotate, and the retraction and release of the pull rope and the elastic principle of the tension spring make the anti-blocking fence slide in the guide hole, so that the anti-blocking fence contacts the filter net when the ventilation louver is opened, preventing the mesh of the filter net from being blocked, thereby improving the ventilation effect of the device.

[0020] Optionally, a solar panel is provided on the top side wall of the main frame facing outdoors, and the solar panel supplies energy to the axial flow fan, temperature and humidity sensor and servo motor in the main frame.

[0021] By adopting the above technical solution, the solar panels arranged on the top side wall of the main frame facing the outdoors can provide power for the axial flow fan, temperature and humidity sensor and servo motor. The use of solar energy for power supply is not only energy-saving and environmentally friendly, but also reduces dependence on external power sources and improves the operating stability of the ventilation structure.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the ventilation system is turned on, the axial flow fan starts to run, sucking in fresh air from the outside through the air inlet and transporting it into the room through the pipe. At the same time, the dirty air in the room is discharged from the air outlet duct, forming an effective exchange of internal and external air. In this process, the setting of the filter improves the air purification ability and ensures that the air entering the room is cleaner. The reasonable layout of the axial flow fan ensures the efficient operation of the ventilation system. The ventilation louvers and their drive components can automatically adjust the opening according to the changes in outdoor temperature and humidity, thereby reducing the risk of rainwater intrusion and enhancing the system's ability to adapt to different weather conditions. The improved unit curtain wall ventilation structure is designed with a central ventilation structure between the upper and lower unit curtain walls, so that the ventilator and the curtain wall structure are separated, and the size, structure and layout of the ventilator can be designed more freely, thereby significantly increasing the ventilation volume and optimizing the indoor and outdoor air exchange efficiency; 2. When the temperature and humidity sensor senses changes in outdoor temperature and humidity, it transmits an electrical signal to the servo motor. After receiving the signal, the servo motor drives the worm to rotate. The rotation of the worm drives the synchronous rotation of several worm wheels meshing with it, realizing the synchronous flipping of several blades, thereby automatically adjusting the opening of the ventilation shutters according to the changes in outdoor temperature and humidity. This design makes the opening and closing of the ventilation shutters more stable and reliable, and improves the overall automation level and ventilation efficiency of the ventilation structure; 3. When the ventilation louver is in a closed state, the surface of the ventilation louver facing the outdoors is flat, and the opposing abutment plates on two adjacent blades are set in contact with each other. Compared with the side walls of two adjacent blades fitting each other, the ventilation louver has higher sealing performance in the closed state, which can effectively prevent leakage caused by rainwater erosion, while improving the safety of the building and reducing maintenance costs.

When the ventilation louver 6 is in a closed state, the surface of the ventilation louver 6 facing the outside is flat, and the opposite stop plates 621 and bristles 622 on two adjacent blades 62 are arranged in abutment with each other; when the ventilation louver 6 is in an open state, the bristles 622 on the blade 62 are arranged in abutment with the adjacent filter screen 7.

[0036] Reference Figure 1 and Figure 3 The main frame 21 is provided with a driving assembly 9 for driving the ventilation louvers 6 to rotate. A cavity is provided in the side wall of the main frame 21. The ends of the six rotating rods 61 on the same side of the embodiment rotate through the side wall of the main frame 21 and extend into the cavity on the same side. The driving assembly 9 includes a worm wheel 91, a worm 92 and a servo motor 93. The worm wheel 91 is fixedly sleeved on the end of the rotating rod 61.

The servo motor 93 is fixedly set in the top cavity of the main frame 21. Its output shaft rotates through the side wall of the main frame 21 and extends into the cavity of the side wall and is coaxially fixedly connected with the worm 92. The servo motor 93 is electrically connected to the temperature and humidity sensor 214.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The anti-blocking fence 8 includes a fence frame 81 and an anti-blocking rod 82. The fence frame 81 is slidably matched with the pipeline. The rotating rod 61 is located in the middle of the channel. The end of the rotating rod 61 that is away from the worm gear 91 extends into the cavity on the other side of the main frame 21. A winding wheel 611 is fixedly sleeved on the end of the rotating rod 61 that extends into the cavity. A guide rod 811 is fixedly set on the side wall of the anti-blocking fence 8 near the winding wheel 611, and the end of the guide rod 811 passes through the side wall of the main frame 21 and extends into the cavity. A pull rope 6111 is fixedly connected between the winding wheel 611 and the corresponding end of the guide rod 811. A guide through hole 217 for the guide rod 811 to pass through is opened on the main frame 21 along the sliding direction of the anti-blocking fence 8. The guide rod 811 and the guide through hole 217 are slidably matched along the length direction of the guide through hole 217.

[0038] Reference Figure 4A fixing rod 218 is fixedly provided on the inner wall of the cavity on the main frame 21, and a fixing rod 218 is provided on one side of the end of each guide through hole 217 away from the winding wheel 611, and a tension spring 8111 is connected and installed between the fixing rod 218 and the corresponding end of the guide rod 811. Under the action of the tension spring 8111, the pull rope 6111 is always in a tensioned state.

[0039] Reference Figure 1 and Figure 2 The anti-blocking rod 82 corresponds to the mesh holes on the filter screen 7 one by one, and is fixedly arranged on the side wall of the fence frame 81 facing the filter screen 7. When the ventilation shutter 6 is in a closed state, the anti-blocking rod 82 is inserted into the mesh holes on the filter screen 7.

[0040] The implementation principle of an improved unit curtain wall ventilation structure in an embodiment of the present application is as follows: under the condition of power supply by the solar panel 213, when the temperature and humidity sensor 214 senses changes in outdoor temperature and humidity, it transmits an electrical signal to the servo motor 93. After receiving the signal, the servo motor 93 drives the worm 92 to rotate. The rotation of the worm 92 drives the multiple worm gears 91 meshing therewith to rotate synchronously, thereby realizing the synchronous flipping of multiple blades 62, thereby automatically adjusting the opening of the ventilation shutters 6 according to changes in outdoor temperature and humidity.

[0041] Driven by the control module 215, the axial flow fan 22 starts to operate, and the fresh air outside is sucked in from the air inlet through the air inlet duct 211, passes through the opening of the ventilation louver 6, the filter 7 and the anti-blocking fence 8 in sequence, and then is delivered to the room from the mesh cover of the protective cover 5. At the same time, the dirty air in the room is discharged from the air outlet duct 212, passes through the anti-blocking fence 8, the filter 7 and the opening of the ventilation louver 6 in sequence, and is output to the outside from the air outlet, forming an effective indoor and outdoor air exchange.

[0042] In the process of the ventilation louver 6 automatically adjusting the opening according to the change of outdoor temperature and humidity, the bristles 622 scrape the surface of the adjacent filter screen 7 as the blades 62 turn over; the rotating rod 61 drives the winding wheel 611 to rotate, and the elastic principle of the pull rope 6111 and the tension spring 8111 makes the anti-blocking fence 8 slide in the guide hole 217. When the ventilation louver 6 is closed, the anti-blocking fence 8 fits with the filter screen 7, and the anti-blocking rod 82 is inserted into the mesh of the filter screen 7 to clear the impurities blocked in the mesh and improve the ventilation effect. Finally, the cleared and scraped dust and impurities slide out of the ventilation structure along the inclined bottom wall of the pipe.

[0043] 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.
