Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and more specifically, to a curtain wall with variable light transmittance for intelligent building construction. Background Technology

[0002] A curtain wall is a building envelope system consisting of panels and a supporting structure that does not bear the stress of the main structure. It is usually composed of panel materials, connectors, supporting structures and sealing materials, and is fixed to the main structure of the building through special installation methods to form a complete building envelope system. It is mainly used in commercial buildings, cultural buildings, transportation buildings and residential buildings.

[0003] A search revealed that publication number CN202131692U discloses a sensor-controlled double-layer energy-saving curtain wall, comprising a double-layer curtain wall and a sensor control system integrated thereon. The double-layer curtain wall includes exhaust equipment and a sunshade device, both controlled by the sensor control system, which includes sensors and an intelligent control module. This system can promptly adjust and control the ventilation and sunshade of the double-layer curtain wall system according to environmental changes, better meeting human comfort requirements, improving the energy utilization efficiency of the double-layer curtain wall, and reducing energy waste. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Traditional curtain walls typically use glass or other materials with fixed light transmittance. However, these materials cannot adjust the light transmittance of the curtain wall in real time according to the intensity of external sunlight and the indoor light requirements. In environments with strong sunlight, traditional curtain walls cannot adjust their light transmittance, resulting in a large amount of light entering the room and causing excessive indoor light, which produces glare. Glare not only affects people's visual comfort but also affects the work efficiency of staff. Furthermore, the existing curtain walls use relatively simple fixing methods, such as relying solely on structural adhesive to fix the glass curtain wall to the frame. This method will cause the structural adhesive, which plays a fixing role, to degrade in performance due to aging during long-term use, thereby weakening the adhesion between the glass and the frame and increasing the safety hazard of glass falling off.

[0005] Therefore, a curtain wall with variable light transmittance for intelligent building construction is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a curtain wall with variable light transmittance for intelligent building construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a curtain wall with variable light transmittance for intelligent building construction, comprising a connecting mechanism, a control component, and an installation component, wherein the control component is placed above the connecting mechanism, and the installation component is installed on the side of the connecting mechanism.

[0008] Preferably, the connecting mechanism includes a sealing strip, electrochromic glass, and a frame assembly, wherein the electrochromic glass is installed on the inner wall side of the frame assembly, and the sealing strip is installed on the side of the electrochromic glass.

[0009] Preferably, the control component includes a light sensor, a microcontroller, and a digitally adjustable resistor, with the microcontroller placed below the light sensor and the digitally adjustable resistor placed below the microcontroller, and the microcontroller integrating a machine learning module.

[0010] Preferably, the mounting assembly includes a bolt, a first anti-vibration washer, and a second anti-vibration washer, wherein the first anti-vibration washer is placed on the outer diameter surface of the bolt, and the second anti-vibration washer is placed on the side of the first anti-vibration washer.

[0011] Preferably, the frame assembly includes a glass clamp, a retaining strip, and a frame, with the retaining strip placed on the side of the frame and the glass clamp installed on the side of the retaining strip away from the frame.

[0012] Preferably, the electrochromic glass is connected to a DC-DC voltage regulator module with an adjustable output voltage of 1-5V and a response time of ≤3 seconds. The frame assembly integrates a 10F supercapacitor, and the frame connection is provided with an Ω-shaped stainless steel expansion joint with a deformation of ±2mm.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with existing technologies, this intelligent building construction variable light transmittance curtain wall can adjust the light transmittance of electroluminescent glass through control components. It can monitor the light conditions outside the curtain wall at different times and seasons through light sensors, and then feed the data back to the control panel. After the control panel processes the data, it transmits the data to the microcontroller, so that the microcontroller can adjust the light transmittance of the electroluminescent glass by controlling the resistance value of the digitally adjustable resistor, so that the indoor light intensity is always appropriate, avoiding glare and insufficient lighting, providing people with a more comfortable visual environment, and reducing people's dependence on artificial lighting.

[0015] 2. Compared with existing technologies, this intelligent building construction variable light transmittance curtain wall uses glass clamps and locking strips to double fix the electrochromic glass, making it less likely for the glass to fall off from the frame assembly. The glass clamps of the frame assembly can directly clamp the glass edge and provide strong mechanical fixing force, which can effectively prevent the glass from falling off when subjected to external force. The locking strips can further fix the glass clamps, so that the glass clamps will not shift or shake in the frame groove, thereby enhancing the stability of the entire curtain wall system and better resisting natural disasters such as strong winds and earthquakes, as well as other external impacts.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 6 The diagram shows a smart building construction variable light transmittance curtain wall, including a connecting mechanism 1, a control component 2, and an installation component 3. The control component 2 is placed above the connecting mechanism 1, and the installation component 3 is installed on the side of the connecting mechanism 1.

[0026] When installing the curtain wall, workers first need to connect the connecting mechanism 1 and the control component 2 with wires, and then fix the connecting mechanism 1 to the curtain wall keel with the installation component 3. When the curtain wall is installed and put into use, the control component 2 will feed back the intensity of the outside light to the control panel. The control panel will then process the data and send it back to the control component 2, so that the control component 2 can adjust the light transmittance of the connecting mechanism 1 to ensure that there is suitable lighting in the room.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0029] In a preferred embodiment, the connecting mechanism 1 includes a sealing strip 4, an electrochromic glass 5, and a frame assembly 6. The electrochromic glass 5 is installed on the inner side of the frame assembly 6, and the sealing strip 4 is adhered to the side of the electrochromic glass 5. When assembling the connecting mechanism 1, the worker needs to fix the electrochromic glass 5 in the frame assembly 6, and then adhere the sealing strip 4 to the connection between the frame assembly 6 and the electrochromic glass 5 to ensure its sealing.

[0030] As a preferred embodiment, the control component 2 includes a light sensor 7, a microcontroller 8, and a digitally adjustable resistor 9. The light sensor 7 absorbs the energy of photons through its internal photodiode, thereby generating electrons and a photocurrent proportional to the light intensity. Then, the amplifier in the light sensor 7 converts the photocurrent into a voltage signal and amplifies it. Next, the integrated analog-to-digital converter converts the amplified analog voltage into a digital signal, which is finally output to the main control device through the communication interface. The light sensor 7 is model BH1750. The microcontroller 8 is based on the independent program memory and data memory, so it can access program instructions and data simultaneously, thereby improving operating efficiency. It also has an internal clock circuit that provides a clock signal to the chip, so that its various circuits can work in an orderly manner according to a certain rhythm. The microcontroller 8 is model Ardu i no Uno R3. The microcontroller 8 is placed below the light sensor 7. The microcontroller (8) integrates a machine learning module, such as TinyML, which predicts user preferences through historical light data and dynamically adjusts the transmittance threshold. Example: During the strong afternoon sunlight in summer, the light transmittance of the west side of the curtain wall is reduced first, while the light transmittance of the east side is maintained at a high level in the morning in winter to absorb heat. A digitally adjustable resistor 9 is placed below the microcontroller 8. The digitally adjustable resistor 9 is an I2C interface digital potentiometer with a resolution of 10 bits and a linear error of ±0.5%. After the curtain wall is put into use, the light sensor 7 will detect the light outside the curtain wall and promptly feed back the light value to the control panel. The control panel will process the data and then transmit the processed data to the microcontroller 8 through manual or automatic adjustment. The microcontroller 8 will then control the strength of the electrical signal transmitted to the connection mechanism 1 by changing the resistance in the digitally adjustable resistor 9.

[0031] In a preferred embodiment, the mounting assembly 3 includes a bolt 10, a first anti-vibration pad 11, and a second anti-vibration pad 12. The first anti-vibration pad 11 is placed on the outer diameter surface of the bolt 10, and the second anti-vibration pad 12 is placed on the side of the first anti-vibration pad 11. When the worker needs to fix the connecting mechanism 1 to the keel of the curtain wall, he first places the first anti-vibration pad 11 and the second anti-vibration pad 12 on the outer diameter surface of the bolt 10, and then aligns the bolt 10 with the holes of the keel and the connecting mechanism 1 and uses a wrench to fix it in the holes.

[0032] In a preferred embodiment, the frame assembly 6 includes a glass clamp 13, a retaining strip 14, and a frame 15. The retaining strip 14 is placed on the side of the frame 15, and the glass clamp 13 is installed on the side of the retaining strip 14 away from the frame 15. When the worker fixes the glass clamp 13, the glass clamp 13 needs to be fixed in the frame groove of the frame 15 with bolts 10. Then, the retaining strip 14 is placed around the glass clamp 13 to prevent the glass clamp 13 from shifting position in the frame groove.

[0033] The electrochromic glass 5 is connected to a DC-DC voltage regulator module with an adjustable output voltage of 1-5V and a response time of ≤3 seconds. The frame component 6 integrates a 10F supercapacitor. The frame 15 is equipped with an Ω-shaped stainless steel expansion joint at the connection point, and the deformation of the Ω-shaped stainless steel expansion joint is ±2mm.

[0034] The working process of this utility model is as follows: First, when installing the curtain wall, the worker needs to fix the glass clamp 13 in the frame groove of the frame 15 with bolts 10 and place the retaining strips 14 around the glass clamp 13 to prevent the glass clamp 13 from shifting position in the frame groove. Next, the electrochromic glass 5 is fixed in the glass clamp 13, and the sealing strip 4 is glued to the connection between the frame 15 and the electrochromic glass 5 to ensure its sealing. Then, the connecting mechanism 1 and the control component 2 are connected by wires. Finally, the connecting mechanism 1 is fixed to the keel of the curtain wall by the mounting component 3. During the process of fixing the connecting mechanism 1 to the keel, the worker must first install the first anti-vibration pad 11 and the second... The shock-absorbing pad 12 is placed on the outer diameter surface of the bolt 10, and then the bolt 10 is aligned with the holes of the keel and the connecting mechanism 1 and fixed in the holes with a wrench to complete the fixation. When the curtain wall is installed and put into use, the light sensor 7 in the control component 2 will detect the light outside the curtain wall and promptly feed back the light value to the control panel. The control panel will process the data and then transmit the processed data to the microcontroller 8 through manual or automatic adjustment. The microcontroller 8 controls the strength of the electrical signal transmitted to the connecting mechanism 1 by changing the resistance in the digital adjustable resistor 9. The above is the working principle of this kind of intelligent building construction variable light transmittance curtain wall.
