Description

Technical Field

[0001] This application relates to the field of building ventilation technology, specifically a smart and eco-friendly self-regulating ventilation structure for building facades. Background Technology

[0002] With the popularization of green building concepts, the energy efficiency and ecological friendliness of building ventilation systems are receiving increasing attention. Traditional building ventilation systems mostly rely on mechanical power, resulting in high energy consumption, and cannot automatically adjust according to environmental conditions. Although some natural ventilation structures exist, they are often single-function and cannot simultaneously meet the multiple requirements of energy saving, intelligence, and ecological purification.

[0003] Existing ventilation technologies have the following shortcomings: First, most rely on electrically driven air supply machinery, which is largely driven by active mechanical ventilation and has high energy consumption; second, they cannot automatically adjust the ventilation status according to environmental changes.

[0004] Therefore, this application provides a smart, eco-friendly building facade self-regulating ventilation structure to solve the above problems. Summary of the Invention

[0005] This application provides an intelligent and eco-friendly self-regulating ventilation structure for building facades, aiming to solve the problems of high energy consumption and poor self-regulation effect of existing ventilation equipment mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a smart ecological building facade self-regulating ventilation structure, comprising a solar panel fixedly installed on the top of the building, environmental sensors installed inside and outside the building, a natural ventilation mechanism installed on the exterior facade of the building, and a controller installed inside the building for regulating the solar panel, environmental sensors, and natural ventilation mechanism. The solar panel is connected to the output terminal of the controller, and the environmental sensor is connected to the input terminal of the controller; The environmental sensors include temperature and humidity sensors, air quality sensors, and wind speed and direction sensors; The natural ventilation mechanism includes a first wind-receiving surface, a second wind-receiving surface, a third wind-receiving surface, and a fourth wind-receiving surface that are circumferentially distributed and sequentially adjacent to each other according to the building's exterior structure. The first wind-receiving surface, the second wind-receiving surface, the third wind-receiving surface, and the fourth wind-receiving surface are provided with high-level ventilation openings and low-level ventilation openings at both high and low levels. The high-level ventilation openings and low-level ventilation openings are symmetrically distributed on two opposite building exterior surfaces. Each of the high-level ventilation openings and low-level ventilation openings is provided with a sealing element for adjusting the opening degree of the cavity. In this way, during use, the wind direction is measured by wind speed and direction sensors. Based on the wind direction information, the controller opens the high and low vents on two opposite walls parallel to the wind direction. For example, the high and low vents on the first and third windward sides are open while the high and low vents on the second and fourth windward sides are closed, or the high and low vents on the second and fourth windward sides are open while the high and low vents on the first and third windward sides are closed. This ensures that the airflow is concentrated and enters the room without being disturbed by the weak airflow from the other two sides. Stable airflow can be guaranteed without excessive use of wind-powered mechanical ventilation. Then, based on the wind speed information, when the wind speed is low, the high and low vents are opened simultaneously to ensure the amount of air entering. When the wind speed is high, only the high or low vents are opened to control the amount of air entering, ensuring stable airflow in the room and reducing interference. Thus, the equipment can automatically adjust the air intake volume and position according to environmental changes, and the controllability is good.

[0007] Preferably, for ease of opening and closing, the sealing component includes a window frame fixedly installed on the inner wall of the high-level ventilation opening and the low-level ventilation opening. A light-transmitting window panel is hinged to the inner wall of the window frame. The window frame is provided with a control component for pushing the light-transmitting window panel toward the exterior of the building facade. The structure is simple, stable, reliable, and has a low failure rate.

[0008] Preferably, in order to control the opening and closing of the skylight panel, the control component is an electric push rod. The control component is electrically connected to the output end of the controller. A first hinge block is fixedly installed on the inner side wall of the window frame at both ends near the skylight panel. A second hinge block adapted to the first hinge block is fixedly installed on the inner side wall of the skylight panel at both ends. The two ends of the control component are respectively hinged to the first hinge block and the second hinge block on the adjacent side, so that the operation is stable and efficient.

[0009] Preferably, in order to enhance the equipment's resistance, pre-embedded holes are provided on the inner walls of both the high-level and low-level ventilation openings, and reinforcing ribs are fixedly installed on the outer wall of the window frame. The reinforcing ribs are inserted into the pre-embedded holes to ensure the overall wind resistance of the equipment.

[0010] Preferably, in order to purify the air, the ventilation structure also includes a gas purification mechanism for purifying the airflow entering the building through the high-level and low-level ventilation openings, ensuring an excellent indoor environment and protecting the health of personnel.

[0011] Preferably, to ensure air cleanliness, the gas purification mechanism includes a hollow mesh frame installed on the inner wall of the high-level and low-level ventilation openings. The outer wall of the hollow mesh frame has flow holes. A primary filter is laid inside the hollow mesh frame facing the outside of the building, and an activated carbon filter is laid inside the hollow mesh frame facing the inside of the building, thereby maximizing air cleanliness.

[0012] Preferably, for ease of maintenance, the hollow space frame has an open design on the side facing the interior of the building, and a detachable baffle is provided at the opening on the hollow space frame. The baffle is fixedly connected to the hollow space frame by bolts for replacement and maintenance.

[0013] Preferably, to ensure both lighting and ventilation, the hollow space frame is detachably connected to the high-level and low-level ventilation openings. Two support blocks are fixedly installed on the interior walls of the building for each of the high-level and low-level ventilation openings. A rotating shaft is rotatably mounted on each of the two support blocks. Both ends of one long side of the hollow space frame are fixedly connected to the two rotating shafts. A servo motor is fixedly installed on one side of one of the rotating shafts on the interior wall of the building. The output shaft of the servo motor is coaxially fixedly connected to the rotating shaft. The servo motor is connected to the output of a controller, thus balancing ventilation and lighting to ensure the indoor environment is not affected.

[0014] Preferably, to ensure sealing, a sealing ring is fixedly installed on the side of the hollow mesh frame opposite to the baffle. The sealing ring is in contact with the interior wall of the building and covers the outside of the high-level ventilation opening and the low-level ventilation opening to ensure the filtration effect.

[0015] This ventilation structure measures wind direction using wind speed and direction sensors. Based on this information, a controller opens two high and low vents on opposite walls parallel to the wind direction. For example, the high and low vents on the first and third windward sides are open while the high and low vents on the second and fourth windward sides are closed, or vice versa. This ensures concentrated airflow into the room, unaffected by weak airflow from other areas. Stable airflow can be maintained without excessive use of mechanical ventilation. Furthermore, based on wind speed information, when the wind speed is low, both high and low vents are opened simultaneously to ensure sufficient airflow. When the wind speed is high, only one vent is opened to control the airflow, ensuring stable airflow and minimizing interference. This allows the equipment to automatically adjust the airflow and position according to environmental changes, resulting in excellent controllability.

[0016] This ventilation structure uses a hollow mesh frame to block the high and low ventilation openings. Airflow passes through the mesh on the surface of the hollow mesh frame. When airflow enters the room from the outside, it first passes through a pre-filter to filter out larger particles, and then passes through an activated carbon filter to adsorb harmful gases, thereby maximizing air cleanliness.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example 1 This embodiment provides an intelligent ecological building facade self-regulating ventilation structure, as shown in Figure x. The ventilation structure includes a solar panel 1 fixedly installed on the top of the building, environmental sensors 2 installed inside and outside the building, a natural ventilation mechanism 3 installed on the exterior of the building, and a controller 4 installed inside the building for regulating the solar panel 1, environmental sensors 2, and natural ventilation mechanism 3. Solar panel 1 is connected to the output terminal of controller 4, and environmental sensor 2 is connected to the input terminal of controller 4; Environmental sensor 2 includes a temperature and humidity sensor, an air quality sensor, and a wind speed and direction sensor; The natural ventilation mechanism 3 includes a first wind-receiving surface 31, a second wind-receiving surface 32, a third wind-receiving surface 33, and a fourth wind-receiving surface 34 that are circumferentially distributed and sequentially adjacent to each other according to the building's exterior structure. The first wind-receiving surface 31, the second wind-receiving surface 32, the third wind-receiving surface 33, and the fourth wind-receiving surface 34 are respectively provided with high-level ventilation openings 35 and low-level ventilation openings 36 at high and low levels. The high-level ventilation openings 35 and low-level ventilation openings 36 on the two opposite building exterior surfaces are symmetrically distributed. The high-level ventilation openings 35 and low-level ventilation openings 36 are each provided with a sealing element 37 for adjusting the opening degree of the cavity.

[0021] During use, the system senses the air environment through an outdoor environmental sensor 2, detects the ambient temperature and humidity through a temperature and humidity sensor, and detects the ambient quality through an air quality sensor to determine whether ventilation mode needs to be activated. If ventilation mode needs to be activated, the specific steps are as follows: Wind direction is measured by wind speed and direction sensors. Based on the wind direction information, the controller 4 opens the high ventilation openings 35 and low ventilation openings 36 on two opposing walls parallel to the wind direction. For example, the high ventilation openings 35 and low ventilation openings 36 on the first windward surface 31 and the third windward surface 33 are open while the high ventilation openings 35 and low ventilation openings 36 on the second windward surface 32 and the fourth windward surface 34 are closed, or the high ventilation openings 35 and low ventilation openings 36 on the second windward surface 32 and the fourth windward surface 34 are open while the high ventilation openings on the first windward surface 31 and the third windward surface 33 are closed. With vents 35 and 36 closed, the airflow is concentrated and enters the room without interference from the other two weak airflows. Stable airflow can be maintained without excessive use of mechanical ventilation. Then, based on the wind speed information, when the wind speed is low, both vents 35 and 36 are opened simultaneously to ensure sufficient airflow. When the wind speed is high, either vent 35 or 36 is opened alone to control the airflow, ensuring stable airflow and reducing interference. This allows the equipment to automatically adjust the airflow and position according to environmental changes, resulting in good controllability.

[0022] Specifically, the sealing component 37 includes a window frame 371 fixedly installed on the inner wall of the high ventilation opening 35 and the low ventilation opening 36. A light-transmitting window panel 372 is hinged to the inner wall of the window frame 371. A control component 373 is provided on the window frame 371 for pushing the light-transmitting window panel 372 toward the outside of the building facade.

[0023] In use, the light-transmitting window panel 372 is opened and closed by the control component 373, so that the high ventilation opening 35 and the low ventilation opening 36 are in an open ventilation state or a closed heat preservation state. The structure is simple, stable and reliable, and has a low failure rate.

[0024] More specifically, the control component 373 is an electric push rod, which is electrically connected to the output end of the controller 4. A first hinge block 3731 is fixedly installed on the inner wall of the window frame 371 at both ends near the light-transmitting window panel 372. A second hinge block 3732 adapted to the first hinge block 3731 is fixedly installed on the inner wall of the light-transmitting window panel 372 at both ends. The two ends of the control component 373 are respectively hinged to the first hinge block 3731 and the second hinge block 3732 on the adjacent sides.

[0025] In use, the control element 373 is hinged to the first hinge block 3731 and the second hinge block 3732. When the window is opened, the output end of the control element 373 pushes the second hinge block 3732 to move and open the light-transmitting window panel 372 outward. When the window is closed, the output end of the control element 373 retracts and pulls back the second hinge block 3732. The operation is stable and efficient.

[0026] Furthermore, pre-embedded holes 38 are provided on the inner walls of both the high ventilation opening 35 and the low ventilation opening 36, and reinforcing ribs 3711 are fixedly installed on the outer wall of the window frame 371, with the reinforcing ribs 3711 inserted into the pre-embedded holes 38.

[0027] During use, the reinforcing ribs 3711 of the window frame 371 are embedded in the pre-embedded holes 38 and then grout is injected to ensure the installation strength of the window frame 371 and ensure the overall wind resistance of the equipment.

[0028] Example 2 Unlike Embodiment 1, when airflow enters the room, the airflow from the external environment usually carries some inhalable particulate matter or polluting gases, which affects the indoor environment and the health of people. Therefore, the ventilation structure also includes a gas purification mechanism 5 for purifying the airflow that flows into the building through the high ventilation opening 35 and the low ventilation opening 36.

[0029] When in use, the gas purification unit 5 purifies the gas flowing into the room, ensuring clean airflow, excellent indoor environment, and the health of personnel.

[0030] Furthermore, the gas purification mechanism 5 includes a hollow mesh frame 51 installed on the inner wall of the high ventilation opening 35 and the low ventilation opening 36. The outer wall of the hollow mesh frame 51 has a flow hole 52. A primary filter screen 53 is laid inside the hollow mesh frame 51 facing the outside of the building, and an activated carbon filter screen 54 is laid inside the hollow mesh frame 51 facing the inside of the building.

[0031] In use, the hollow mesh frame 51 is used to block the high ventilation opening 35 and the low ventilation opening 36. The airflow flows through the mesh on the surface of the hollow mesh frame 51. When the airflow flows from the outside into the room, it first passes through the primary filter 53 to filter larger particles, and then passes through the activated carbon filter 54 to adsorb harmful gases, thereby maximizing the air cleanliness.

[0032] Furthermore, the hollow space frame 51 has an open design on the side facing the interior of the building, and a detachable baffle 55 is provided at the opening on the hollow space frame 51. The baffle 55 is fixedly connected to the hollow space frame 51 by bolts.

[0033] In use, the baffle 55 is detachably connected to the hollow mesh frame 51 by bolts, so that the primary filter 53 and activated carbon filter 54 inside the hollow mesh frame 51 can be removed for replacement and maintenance.

[0034] Specifically, the hollow space frame 51 is detachably connected to the high ventilation opening 35 and the low ventilation opening 36. The high ventilation opening 35 and the low ventilation opening 36 are fixedly installed on the inner wall of the building with two support blocks 56. Each support block 56 is rotatably mounted with a rotating shaft 57. The two ends of one long side of the hollow space frame 51 are fixedly connected to the two rotating shafts 57 respectively. One side of one of the rotating shafts 57 is fixedly mounted on the inner wall of the building with a servo motor 58. The output shaft of the servo motor 58 is coaxially fixedly connected to the rotating shaft 57. The servo motor 58 is connected to the output end of the controller 4.

[0035] When ventilation is needed, the controller 4 starts the servo motor 58, which drives the rotating shaft 57 to rotate. This causes the hollow mesh frame 51 at the corresponding open high ventilation opening 35 and low ventilation opening 36 to be attached to the wall, blocking the ventilation openings 35 and 36. This forces the airflow to pass through a filter before entering the room. Meanwhile, the hollow mesh frame 51 at the unventilated high ventilation opening 35 and low ventilation opening 36 is kept on the wall below the openings by the servo motor 58, ensuring normal lighting. This balances ventilation and lighting, ensuring that the indoor environment is not affected.

[0036] More specifically, a sealing ring 59 is fixedly installed on the side of the hollow space frame 51 opposite to the baffle 55. The sealing ring 59 is attached to the interior wall of the building and covers the outside of the high ventilation opening 35 and the low ventilation opening 36.

[0037] When in use, the hollow mesh frame 51 is attached to the inner wall of the high ventilation opening 35 and the low ventilation opening 36 during ventilation. The sealing ring 59 is attached to the wall, so that the airflow can only pass through the hollow mesh frame 51 and must be filtered before entering the room. It cannot pass through the gap between the edge of the hollow mesh frame 51 and the wall, thus ensuring the filtration effect.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
