Description

Technical Field

[0001] This invention relates to the field of building energy conservation and environmental governance technology, and in particular to an adjustable vertical greening system and control method based on wind and heat environment response. Background Technology

[0002] As living standards improve, residents' demand for diverse residential green spaces is increasing, making vertical greening an important means of improving residential greening design. Vertical greening involves planting vegetation on the facade of a building, ensuring that the plants can grow vertically while also considering building safety, ease of maintenance, and water and energy conservation. Vertical greening can effectively improve the building's thermal environment, reduce energy consumption, and also play a positive role in improving the urban microclimate and reducing dust and noise.

[0003] Current building vertical greening systems suffer from the following problems: planting troughs are fixedly connected to the building facade or supports, making them difficult to replace and resulting in poor cooling effects; existing vertical greening systems mostly adopt an integrated arrangement of planting modules and supporting structures, where the entire structure either rotates synchronously or remains fixed under strong winds or high temperatures, making it difficult to balance structural safety, shading effect, and plant growth needs. Furthermore, different plants have significantly different requirements for light, ventilation, and stability, and the integrated greening structure lacks independent adjustment capabilities for different functional areas, leading to insufficient system operational flexibility and limited ecological and energy-saving effects. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide an adjustable vertical greening system and control method based on wind and heat environment response, in order to solve one of the problems of poor cooling effect and maintenance difficulty of existing vertical greening, as well as the inflexible thermal environment adjustment caused by the linkage of the overall greening modules with the climbing frame and the inability to differentiate ecological functions.

[0005] On the one hand, the present invention provides an adjustable vertical greening system based on wind and heat environment response, including multiple vertical greening module units, which are arranged in rows along the exterior facade of a building with windows; The vertical greening module unit includes a climbing frame and a box-type planting trough. The box-type planting trough is connected to the climbing frame and is divided into a shade area, an ecological decoration area, and a shade-tolerant and moisture-retaining area from top to bottom along the height direction of the climbing frame.

[0006] Furthermore, the vertical greening module unit also includes an adjustable connection mechanism, one end of which is connected to the exterior wall of the building, and the other end is connected to the climbing frame.

[0007] Furthermore, it also includes rainwater collection devices installed on the roof.

[0008] Furthermore, the vertical greening module unit also includes a sprinkler pipe, which is horizontally positioned above the box-type planting trough.

[0009] Furthermore, it also includes a drain pipe, one end of which is connected to the rainwater collection device and the other end of which is connected to the spray pipe.

[0010] Furthermore, multiple drip irrigation nozzles are evenly arranged along the length of the spray pipe.

[0011] Furthermore, it also includes a temperature sensor for collecting ambient temperature.

[0012] Furthermore, it also includes an anemometer for collecting environmental speed data.

[0013] Furthermore, it also includes a solar power module.

[0014] On the other hand, the present invention provides a control method based on wind and heat environment response to control the angles of the climbing frame and shading components of the above-mentioned adjustable vertical greening system.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: (1) This invention provides vertical greening module units on the exterior facade of buildings with windows. Each vertical greening module unit includes a climbing frame and box-type planting troughs. The climbing frames are arranged in rows along the exterior facade, and the box-type planting troughs are connected to the climbing frames. The climbing frames are divided into a shade area, an ecological decoration area, and a shade-tolerant and moisture-retaining area along their height. The shade area is located above the ecological decoration area, and the shade-tolerant and moisture-retaining area is located below the ecological decoration area. Corresponding plant types are planted in the box-type planting troughs in different areas, achieving differentiated ecological functions of vertical greening. This allows for adaptable and complementary vertical greening zones, enhancing ecological benefits and landscape practicality.

[0016] (2) The box-type planting trough of the present invention has a split structure, which is divided into a planting trough body and a pull-out trough body. The pull-out bottom plate is provided with a slide rail, and the planting trough body is provided with a slide groove, so as to realize the detachable connection between the pull-out bottom plate and the planting trough body, which facilitates the maintenance of the box-type planting trough and the replacement of soil, thereby shortening the maintenance time of the box-type planting trough and green plants.

[0017] (3) The present invention divides the internal area of ​​the climbing frame into multiple independently adjustable greening module zones. Each greening module zone is equipped with multiple box-type planting troughs. Individual greening module zones can be independently adjusted or coordinated with the entire climbing frame according to the needs of light and ventilation. The adjustment method is flexible and can obtain a better combination of light, ventilation and environmental comfort.

[0018] (4) This invention uses an anemometer and temperature sensor to monitor the ambient wind speed and temperature in real time, and intelligently controls the tilt angle of the vertical greening module unit and the timing of spraying based on the acquired data. In particular, by adjusting the tilt angle of the climbing frame, the impact of wind load on the building can be effectively reduced under strong wind conditions, while ensuring that the windows can be opened; in addition, combined with spraying and shading measures, the surface temperature of the building can be significantly reduced, thereby effectively reducing the energy consumption of the air conditioning system and improving the overall energy-saving effect.

[0019] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention.

Detailed Implementation

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0024] Example 1 To address the problem that existing vertical greening systems cannot achieve differentiated ecological functions, a specific embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, an adjustable vertical greening system based on wind and heat environment response is disclosed, including multiple vertical greening module units 1. The multiple vertical greening module units 1 are arranged in rows along the exterior facade of a building with windows. The vertical greening module unit 1 includes a climbing frame 11 and a box-type planting trough 12. The box-type planting trough 12 is connected to the climbing frame 11. Along the height direction of the climbing frame 11, it is divided into a shade area 111, an ecological decoration area 112, and a shade-resistant and moisture-retaining area 113 from top to bottom.

[0025] Compared with existing technologies, the adjustable vertical greening system based on wind and heat environment response provided in this embodiment sets up vertical greening module units 1 on the exterior facade of a building with windows. The vertical greening module unit 1 includes climbing frames 11 and box-type planting troughs 12. The climbing frames 11 are arranged in rows along the exterior facade, and the box-type planting troughs 12 are connected to the climbing frames 11. Along the height direction of the climbing frames 11, they are divided into a shade area 111, an ecological decoration area 112, and a shade-tolerant and moisture-retaining area 113. The shade area 111 is located above the ecological decoration area 112, and the shade-tolerant and moisture-retaining area 113 is located below the ecological decoration area 112. Corresponding plant types are planted in the box-type planting troughs 12 in different areas, achieving differentiated ecological functions of vertical greening. This allows for adaptable and complementary vertical greening zones, improving ecological benefits and landscape practicality.

[0026] Since the box-type planting trough 12 is installed on the climbing frame 11, and the climbing frame 11 is arranged on the building facade with windows, the climbing frame 11 needs to be rotated to meet the needs of shading and ventilation. Figure 2 and Figure 3 As shown, the vertical greening module unit 1 also includes an adjustable connection mechanism 13. One end of the adjustable connection mechanism 13 is connected to the exterior wall of the building, and the other end is connected to the climbing frame 11. When it is necessary to adjust the angle of the climbing frame 11, the extension and retraction of the adjustable connection mechanism 13 are controlled, so that the climbing frame 11 tilts or deflects.

[0027] There are multiple adjustable connection mechanisms 13, generally four. The four adjustable connection mechanisms 13 are respectively connected to the four corners of the climbing frame 11. Understandably, the adjustable connection mechanisms 13 and the climbing frame 11 are rotatably connected. For example, when the two upper adjustable connection mechanisms 13 extend or retract, the upper part of the climbing frame 11 moves away from the building facade and deflects about the bottom of the climbing frame 11 as the axis. When the adjustable connection mechanisms 13 on the same vertical side extend or retract, the left or right side of the climbing frame 11 moves away from the building facade and deflects about one side of the vertical direction of the climbing frame 11 as the axis.

[0028] Preferably, the adjustable connecting mechanism 13 is an electric telescopic rod.

[0029] Furthermore, in order to address the difficulties in maintaining existing vertical greening systems, such as... Figure 2 and Figure 3 As shown, the box-type planting trough 12 includes a planting trough body 121 and a pull-out bottom plate 122, with the pull-out bottom plate 122 located at the bottom of the planting trough body 121. Figure 4 As shown, the pull-out base plate 122 is detachably connected to the planting trough 121. Specifically, a groove 123 is provided on the inner wall of the planting trough 121, and slide rails 124 are provided on both sides of the pull-out base plate 122. The slide rails 124 cooperate with the groove 123, allowing the pull-out base plate 122 to be quickly installed and removed from the planting trough 121. When it is necessary to replace the soil in the planting trough, there is no need to dig the soil from the top of the planting trough 121. Simply pull out the pull-out base plate 122, and the soil will quickly fall from the bottom of the planting trough 121. Then, push the pull-out base plate 122 back to the sealing position and add new soil.

[0030] In this embodiment, the box-type planting trough 12 has a split structure, consisting of a planting trough body 121 and a pull-out bottom plate 122. The pull-out bottom plate 122 is provided with a slide rail 124, and the planting trough body 121 is provided with a slide groove 123, so that the pull-out bottom plate 122 and the planting trough body 121 can be detachably connected, which facilitates the maintenance of the box-type planting trough 12 and the replacement of soil, thereby shortening the maintenance time of the box-type planting trough 12 and the green plants.

[0031] It is worth noting that multiple box-type planting troughs 12 are provided at the same horizontal height, preferably three.

[0032] To conserve resources, rainwater is used to irrigate the plants in the box-type planting trough 12; therefore, the adjustable vertical greening system also includes a rainwater harvesting device 2, such as... Figure 1 As shown, the rainwater collection device 2 is installed on the roof, and a filter screen is installed above the rainwater collection device 2 to filter out debris such as fallen leaves and branches. Preferably, the rainwater collection device 2 is a box or bucket with a filter screen that can store rainwater.

[0033] In order to deliver rainwater from the rainwater collection device 2 to the box-type planting trough 12, such as Figure 1 , Figure 2 and Figure 3 As shown, the adjustable vertical greening system also includes a drop pipe 3, and the vertical greening module unit 1 also includes a sprinkler pipe 14. The sprinkler pipe 14 is horizontally positioned above the box-type planting trough 12, and multiple drip irrigation nozzles 15 are evenly arranged along the length of the sprinkler pipe 14. One end of the drop pipe 3 is connected to the rainwater collection device 2, and the other end is connected to the sprinkler pipe 14.

[0034] In this embodiment, the rainwater collection device 2 and the spray pipe 14 are connected by the sliding pipe 3. The rainwater collected by the rainwater collection device 2 is transported to the spray pipe 14 through the sliding pipe 3. The spray pipe 14 then sprays the rainwater evenly through the drip irrigation nozzle 15 to achieve the purpose of spraying and cooling.

[0035] Furthermore, in order to address the problem of poor cooling effect in existing vertical greening systems, such as... Figure 2 As shown, the vertical greening module unit 1 also includes fans 16, and multiple fans 16 are evenly arranged along the width direction of the climbing frame 11. Preferably, the fans 16 are installed on the box-type planting trough 12. The fans 16 are located behind the sprinkler pipe 14 and blow air towards the drip irrigation nozzle 15.

[0036] In this embodiment, the fan 16 is installed behind the spray pipe 14. When the fan 16 and the spray are turned on, the fan 16 blows the water droplets sprayed from the drip irrigation nozzle 15 into atomized form, which can further improve the cooling effect.

[0037] Since the climbing frame 11 will deflect as needed, and the two ends of the drop pipe 3 are respectively connected to the rainwater collection device 2 on the roof and the sprinkler pipe 14 on the box-type planting trough 12, in order to avoid the rigid drop pipe 3 interfering with the rotation of the climbing frame 11, the end of the drop pipe 3 is connected to the sprinkler pipe 14 through a flexible pipe.

[0038] In order to control the rotation of the climbing frame 11, such as Figure 1 As shown, the adjustable vertical greening system also includes a temperature sensor 4, an anemometer 5, a solar power module 6, and a control unit (not shown in the figure). The temperature sensor 4 is used to acquire the ambient temperature and humidity, and the anemometer 5 is used to monitor the ambient wind speed in real time. The control unit controls the rotation of the climbing frame 11 according to the environmental parameters. The solar power module 6 supplies power to the electrical equipment in the system.

[0039] In this embodiment, temperature sensor 4 and anemometer 5 collect ambient wind speed and temperature data in real time, and dynamically adjust the tilt angle of the vertical greening module unit and the timing of the sprinkler operation based on the acquired data. Specifically, when the ambient wind speed... When the speed is ≥5m / s, the adjustable connecting mechanism 13 can adjust the tilt angle of the climbing frame 11, and adaptively adjust the tilt angle to keep it within 0° < The angle variation within 45° effectively reduces the impact of strong winds on the building facade, thereby reducing the structure's windward area and wind load, while ensuring that windows can be opened. This design solves the problem of difficulty in opening windows for ventilation under strong wind conditions, and also achieves natural ventilation while providing shading, thus improving the thermal comfort of the indoor environment.

[0040] Example 2 Furthermore, to address the problem of inflexible thermal environment adjustment caused by the linkage between existing vertical greening modules and climbing frames, another specific embodiment of the present invention discloses an adjustable vertical greening system based on wind and heat environment response, such as... Figure 5 As shown, the difference from Embodiment 1 is that the internal area of ​​the climbing frame 11 is divided into multiple independently adjustable greening module sections 114. Each greening module section 114 is equipped with multiple box-type planting troughs 12. The greening module sections 114 are rotatably connected to the outer frame 115 of the climbing frame 11, and each greening module section 114 is connected to an angle adjustment mechanism 17. The angle adjustment mechanism 17 enables independent adjustment of the deflection angle of the greening module section 114.

[0041] Compared with the prior art, the adjustable vertical greening system based on wind and heat environment response provided in this embodiment divides the internal area of ​​the climbing frame 11 into multiple independently adjustable greening module partitions 114. Each greening module partition 114 is equipped with multiple box-type planting troughs 12. Individual greening module partitions 114 can be independently adjusted or coordinated with the entire climbing frame 11 according to the needs of light and ventilation. The adjustment method is flexible and can obtain an optimal combination of light, ventilation and environmental comfort.

[0042] Specifically, such as Figure 5 The angle adjustment mechanism 17 includes a first connecting plate 171, a first rotating shaft 172, a first motor 173, a connecting frame 174, a second rotating shaft 175, a second motor 176, and a second connecting plate 177. The first connecting plate 171 is connected to the first rotating shaft 172. The first motor 173 drives the first rotating shaft 172 to rotate. The first connecting plate 171 is rotatably connected to the outer frame 115 through the first rotating shaft 172. The connecting frame 174 is fixedly installed on the first connecting plate 171. The second connecting plate 177 is rotatably connected to the connecting frame 174 through the second rotating shaft 175. The second motor 176 drives the second rotating shaft 175 to rotate. The box-type planting trough 12 is connected to the second connecting plate 177.

[0043] In this embodiment, temperature sensor 4 and anemometer 5 collect ambient wind speed and temperature data in real time, and dynamically adjust the tilt angle of the vertical greening module unit 1 and the timing of the sprinkler operation based on the acquired data. Specifically, when the ambient wind speed... When the speed is ≥5m / s, the adjustable connecting mechanism 13 can adjust the tilt angle of the climbing frame 11, and adaptively adjust the tilt angle to keep it within 0° < The angle variation within 45° effectively weakens the impact of strong winds on the building facade, reducing the windward area of ​​the structure and lowering the wind load, while ensuring that the windows can be opened. This design not only solves the problem of difficulty in opening windows for ventilation under strong wind conditions, but also achieves natural ventilation while providing shading, thereby improving the thermal comfort of the indoor environment.

[0044] When temperature sensor 4 detects the ambient temperature >29℃, and the ambient wind speed measured by an anemometer 5 When the wind speed is <5 m / s, the system activates drip irrigation nozzles 15 and turns on fans 16 for coordinated spraying and cooling. This measure can lower the building surface temperature, thereby effectively reducing the energy consumption of the air conditioning system and improving the overall energy-saving effect. When the ambient wind speed is 5 m / s ≤ 5m / s and ambient temperature At temperatures above 29℃, spray water droplets are prone to significant drift and separation from the target area under aerodynamic forces, resulting in a significant decrease in evaporative cooling efficiency and even ineffective operation. Therefore, under this condition, the spray system is shut down, and the building surface temperature is reduced by adjusting the tilt angle of the climbing frame 11 shading module (greening module partition 114), thereby reducing air conditioning energy consumption.

[0045] Example 3 Furthermore, to address the problem of inflexible thermal environment adjustment caused by the linkage between existing vertical greening modules and climbing frames, another specific embodiment of the present invention discloses a control method based on wind and heat environment response, employing the adjustable vertical greening system of Embodiment 2, comprising the following steps: Step S1: Construct the control function model of the climbing frame 11 and the sunshade component.

[0046] Since both the climbing frame 11 and the greening module partition 114 (shading component) can rotate, the control models include: a wind speed-climbing frame rotation angle function model for the climbing frame 11, and a temperature-shading angle continuous function model for the shading component. For the control of the climbing frame 11, the rotation angle of the climbing frame 11... for:

[0047] in, The maximum rotation angle of climbing frame 11 is set to 45°. Real-time ambient wind speed; The wind speed threshold for the initial rotation of climbing frame 11 is set to 5 m / s; The rotation angle of the climbing frame 11 is less than 0°. The climbing frame 11 can rotate within a range of <45°, provided that the ambient wind speed is ≤5m / s. 5m / s and satisfy Only then can adjustments be made. , Set to 0.5 m / s.

[0048] In this embodiment, by restricting the rotation conditions of the climbing frame 11, rotation is only allowed when 5m / s ≤ The climbing frame 11 will only rotate when the ambient wind speed is 5 m / s and the difference between the current ambient wind speed and the previous ambient wind speed is greater than 0.5 m / s. This can effectively reduce the frequent small vibrations of the climbing frame 11 caused by minor fluctuations in wind speed, making the system structure safer and more reliable.

[0049] It should be noted that, This is the average ambient wind speed over the current 20 minutes, which is the average value obtained by the anemometer 5 collecting wind speed parameters every minute. The average ambient wind speed obtained in the previous data collection period (20 minutes); that is:

[0050] In this embodiment, because the climbing frame 11 can rotate with the wind direction to reduce the windward area, the wind pressure on the external structure is significantly reduced, thereby weakening the impact of wind vibration and airflow disturbance on the transparent enclosure structure, effectively reducing wind noise and vibration perception in the residents' homes, and improving living safety and comfort. At the same time, the downwind state of the climbing frame 11 makes the wind field near the exterior windows more stable, which is conducive to improving thermal comfort under natural ventilation conditions.

[0051] For the regulation of the shading component (i.e., greening module 114), the temperature-shading angle continuous function model of the shading component is as follows: When the ambient wind speed is less than the critical wind speed threshold (i.e.) )hour,

[0052] When the ambient wind speed is not less than the critical wind speed threshold (i.e.) )hour,

[0053] in, The left and right shading angles of the shading component; The upper and lower shading angles of the shading component; The adjusted left and right sunshade angles of the sunshade components; The adjusted upper and lower shading angles of the shading components.

[0054]

[0055]

[0056]

[0057]

[0058]

[0059] in, The wind speed critical threshold for the left and right rotation execution angle of the shading component is used to determine whether to weaken the execution of the shading adjustment action. The wind speed critical threshold is set according to the structural form and installation conditions of the greening module, and is preferably 13m / s. The maximum permissible angle for shading on the left and right sides of the shading component is set to 45°. The solar azimuth angle is defined as 0° for due north and 0° for east. The building facade orientation angle is defined as north as 0° and east as positive. The reference azimuth scale is set to 90° to keep the angle difference within a reasonable range; K is the spatial distribution adjustment coefficient, where... Characterizing the differences in shading needs at different heights, This is the distance from the bottom of the shading component to the bottom of the area occupied by all shading components. It is half the height of the area occupied by all shading components. The height of the area occupied by all shading components; Used to characterize the differences in shading needs at different horizontal locations; Shading angle constructed for shading under temperature T; The maximum permissible shading angle for top and bottom shading is 30°; The ambient temperature or the detected outdoor air temperature; The initial temperature threshold for shading adjustment is set to 29℃; The upper temperature limit corresponding to the maximum value of the shading angle is set to 35℃; N is the control index, with a value of 2. As the temperature gradually increases, the change range of the shading angle gradually becomes larger.

[0060] Understandably, similar to climbing frame 11, the rotation condition of the sunshade component is as follows: Only then will adjustments be made. , Set to 1℃.

[0061] It should be noted that, This is the average ambient temperature over the current 20 minutes, which is the average value obtained by temperature sensor 4 collecting temperature parameters every minute. The average ambient temperature obtained in the previous data collection cycle (20 minutes); that is:

[0062] In high temperature and strong wind ( Under conditions of ≥13m / s, for safety reasons, the shading angle can be appropriately reduced, and a shading angle suppression coefficient can be introduced.

[0063] Shading angle suppression coefficient: (wind-heat coupling)

[0064] Under these conditions:

[0065]

[0066] Step S2: Obtain the current ambient wind speed Given the current ambient temperature T, determine whether the current ambient wind speed meets the condition 5m / s≤ ≤15m / s, otherwise maintain the current state of climbing frame 11, if so, proceed to step S3; determine whether the current ambient temperature satisfies T0<T<T max If yes, proceed to step S4; otherwise, determine if the current ambient temperature satisfies T0≥T. If yes, keep the shading component vertical; otherwise, adjust the shading angle of the shading component. If the current ambient wind speed is less than 5m / s and the ambient temperature is greater than 29℃, start the sprinklers and fan 16; otherwise, turn them off.

[0067] Step S3: Determine if the condition is met. If not, the current angle of the climbing frame 11 remains unchanged; if yes, the wind speed-climbing frame rotation angle function model is called to adjust the angle of the climbing frame 11.

[0068] Step S4: Determine if the condition is met. If not, the current angle of the shading component remains unchanged; if yes, the temperature-shading angle continuous function model is called to adjust the angle of the shading component.

[0069] In this embodiment, when the ambient temperature is lower than or equal to the starting temperature... At this time, no shading adjustment is required; the shading components remain basically vertical with a zero shading angle to ensure the building facade's lighting and natural ventilation performance. When the ambient temperature is between and During this period, the shading angle of the shading components increases linearly with temperature changes, gradually increasing as temperature rises. This ensures the shading effect matches the environmental heat load, preventing abrupt changes in shading action and improving system stability. When the ambient temperature reaches or exceeds [a certain value], [the shading angle will increase]. When the shading angle of the upper and lower shading components reaches the maximum control angle of 30°, and the shading angle of the left and right shading components reaches the maximum control angle of 45°, the system enters a stable shading state, preventing the shading angle from continuing to increase and adversely affecting structural safety and functionality.

[0070] In this embodiment, ambient wind speed and temperature data are acquired in real time through temperature sensor 4 and anemometer 5. The tilt angle of climbing frame 11 and sunshade components and the timing of spraying are adjusted according to the wind speed and temperature data. Individual greening module zones can be independently controlled or coordinated with the entire climbing frame according to the needs of lighting and ventilation. The control method is flexible and can obtain the best combination of lighting, ventilation and environmental comfort, reducing ambient temperature and air conditioning energy consumption.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
