Description

Technical Field

[0001] This patent relates to a photovoltaic curtain wall, in particular to an intelligent photovoltaic curtain wall with adjustable light transmittance. Background Art

[0002] The roof area of ​​urban buildings is very small compared to the wall area. The development of photovoltaic power generation in cities requires the development of photovoltaic curtain wall technology. When building photovoltaic curtain walls, the photovoltaic curtain walls formed by the commonly used photovoltaic modules are not transparent as a whole, and the buildings composed of such opaque photovoltaic curtain walls are not suitable for people's living and working requirements. For this reason, people have developed some partially transparent photovoltaic films such as cadmium telluride thin film batteries, perovskite batteries, and semi-transparent silicon-based batteries. Among them, cadmium telluride thin film batteries and semi-transparent silicon-based batteries have mature products and have been used in some photovoltaic curtain walls. The light transmittance of photovoltaic curtain walls composed of these photovoltaic modules is basically fixed, but people have different needs for building light transmittance at different times when living and working. In the morning or rainy days, high light transmittance is required to obtain appropriate light intensity indoors. At noon or under the scorching sun, relatively small light transmittance is required to make the indoor environment relatively comfortable. The existing photovoltaic curtain walls are difficult to meet people's needs for indoor light intensity comfort. Therefore, there is a need for an intelligent photovoltaic curtain wall with automatically adjustable light intensity to meet people's needs for indoor light intensity changes during study and life, and to improve indoor comfort. The present invention provides an intelligent photovoltaic curtain wall with adjustable light intensity, which can automatically adjust the transmittance of photovoltaic modules in the curtain wall according to the needs of indoor light intensity, so that the indoor light intensity changes automatically in real time, meets the needs of indoor light intensity changes, and improves living comfort. Summary of the invention

[0003] In order to achieve the purpose of the present invention, the present invention provides an intelligent photovoltaic curtain wall with adjustable light transmittance, characterized in that the support body (2) installed longitudinally and transversely in the photovoltaic curtain wall is located behind the photovoltaic module array composed of photovoltaic cell modules (1), the photovoltaic cell modules (1) are fixed by longitudinal and transverse module fasteners (3) located on the support body (2), the support body (2) adopts a ceramic steel or reinforced concrete structure with a ceramic protective film, and there are longitudinally and transversely distributed inter-module pore channels (4) between the photovoltaic cells, which are used to adjust the temperature balance of the photovoltaic cell module (1) array, and when necessary, constant temperature gas or liquid can be circulated to achieve a constant temperature effect of the photovoltaic curtain wall. The photovoltaic cells (5) in the photovoltaic cell assembly (1) are located between two guide rails (6), there is a cell gap (7) between the photovoltaic cells (5), and they are enclosed between two layers of glass (12) of the photovoltaic assembly (1) to realize modularization of the assembly; the two guide rails (6) are respectively connected to their respective drive motors (4), the drive motor (4) is connected to the controller (9) via a data connection (10), and the drive motor (4), the controller (9) and the connecting line (10) are installed in a photovoltaic cell storage box (11). The method for automatically adjusting the light transmittance intensity of the photovoltaic curtain wall is that the controller (9) in the photovoltaic cell assembly (1) calculates the area ratio requirement (i.e., the area ratio α, α) on the photovoltaic cell assembly (1) that needs to be blocked by the photovoltaic cell (5) according to the user's light transmittance intensity requirement. Where S n is the area of ​​photovoltaic cells distributed on the surface of the photovoltaic module, S dThe invention discloses a method for distributing the photovoltaic cells (5) in a photovoltaic cell assembly (1) to a plurality of photovoltaic cells (5) in a plurality of photovoltaic cells (5). The method comprises: transmitting a command to a driving motor (4) to drive the guide rail, driving the photovoltaic cells (5) to move along the guide rail, and realizing the width adjustment of the gap (7) between the photovoltaic cells (5). The photovoltaic cells (5) in the photovoltaic cell assembly (1) are distributed in the photovoltaic assembly (1) according to the requirements of the α value. The distribution method can be arranged in an equidistant linear arrangement or a nonlinear arrangement according to the requirements of the user, and can even be arranged according to certain artistic requirements to present a certain artistic pattern, thereby beautifying the environment and realizing the automatic adjustment of α, thereby achieving the effect of automatically adjusting the light transmission intensity.

[0004] The beneficial effects of the present invention are:

[0005] 1. The present invention controls the light transmittance by adjusting the area ratio of the battery in the photovoltaic module, combines mechatronics technology, and uses artificial intelligence to realize real-time automatic adjustment of the light transmittance of the photovoltaic curtain wall. Unlike the existing photovoltaic curtain wall based on cadmium telluride thin film batteries, which achieves partial transparency by changing the battery composition and structure, the photovoltaic curtain wall of the present invention has no special requirements for the light transmittance of the battery. It does not require the development of special light-transmitting thin-film batteries, but through artificial intelligence and mechatronics technology, it can provide a photovoltaic curtain wall that adapts to the needs of indoor lighting changes in different time periods and seasons. At present, most commercial photovoltaic cells including monocrystalline silicon and polycrystalline silicon can be applied to the present invention, thereby expanding the application range of silicon-based batteries. This not only plays the environmental advantages and mature technology of silicon-based batteries, but also brings cost-effectiveness, so that it is widely used in occasions where partial light transmission is required, such as waiting halls, planting greenhouses and office building curtain walls. It helps to promote the development of photovoltaic curtain wall technology.

[0006] 2. The present invention relates to an intelligent photovoltaic curtain wall, whose light transmittance is adjustable. The curtain wall adopts advanced light transmittance adjustment technology, which can adjust its light transmittance performance dynamically in real time according to demand. Compared with the currently popular cadmium telluride thin film battery, although the latter can achieve a certain degree of light transmittance and generate electricity, once the thin film material is made, the light transmittance is fixed and the light transmittance cannot be adjusted in time according to actual needs. In contrast, the present invention can realize the timely intelligent adjustment of the light transmittance of photovoltaic components in the photovoltaic curtain wall through mechatronics and intelligent control technology. The adjustment process receives user instructions through the controller, supports multiple input methods such as panel input, voice input or remote mobile phone operation, and the algorithm program in the controller will calculate the required parameters and generate control commands to drive the motor to move, thereby adjusting the occupancy ratio of the photovoltaic components and realizing precise control of the light transmittance of the curtain wall. This timely intelligent adjustment method ensures that the photovoltaic curtain wall has an ideal light transmittance, so that the interior of the building can obtain the required light distribution, significantly improves the comfort of the indoor environment, and can be used to build a livable building. In addition, the controller used in the photovoltaic curtain wall can be implanted with AI programs to accumulate data such as light transmittance, ambient weather and temperature that users usually use. Through AI deep learning, it can understand the user's usage habits, optimize the default settings of the controller, and improve the convenience of users using the system. It can also be connected with the control data of similar photovoltaic curtain walls and usage requirements in the surrounding area through the Internet of Things, learn from each other and optimize, so that the selection of control parameters is more reasonable, and a more comfortable light intensity is provided for the use space.

[0007] 3. The photovoltaic curtain wall involved in the present invention has the ability to differentially adjust the local light intensity of the curtain wall, thereby realizing the local differentiated control of the indoor light intensity. In specific application scenarios, this adjustment function has significant practical application value. For example, in office buildings or residential buildings, by using the wall composed of this photovoltaic curtain wall, on sunny days in winter, adjusting the light intensity of the photovoltaic components can make certain areas of the room get sufficient sunlight, thereby improving the comfort of the working environment. At the same time, for those parts that do not need direct sunlight, full coverage can be achieved to obtain better photovoltaic power generation efficiency. This photovoltaic curtain wall is applied to the planting greenhouse, and local adjustments can be made according to the needs of different plants for light intensity. Compared with the existing planting site that only provides a single light intensity, the photovoltaic curtain wall with differentiated light intensity provided by the present invention can ensure that both light-loving plants and shade-loving plants receive appropriate light, thereby promoting the healthy growth of plants. The wide application of this differentiated light intensity field in the planting greenhouse is also conducive to promoting the study of the differences in suitable light intensity for various plants, accumulating data on plant species and suitable light intensity for each growth stage, and establishing a corresponding database. Doing so is extremely beneficial for promoting plant growth, increasing yields and planting species diversity.

[0008] 4. The intelligent photovoltaic curtain wall system involved in the present invention, wherein the photovoltaic cells contained in the photovoltaic modules used, in order to achieve better light transmission intensity adjustment accuracy, usually use photovoltaic cells with smaller width, the size of which is at the centimeter level. Compared with traditional large-sized and expensive photovoltaic cells, such small-sized photovoltaic cells can be manufactured using smaller-sized single-crystal silicon materials. This approach not only helps to reduce the production cost of photovoltaic cells, but also has a relatively low probability of color difference in small-sized cells, so it is more ideal in visual effect. In addition, since photovoltaic cells often need to be moved in photovoltaic curtain wall components, the sensitivity of the entire photovoltaic curtain wall to the color difference of photovoltaic components is not as strong as that of fixed photovoltaic curtain walls. Therefore, the anti-color difference requirements for components are not as strict as those for large-sized fixed photovoltaic curtain walls. In order to meet the environmental requirements for the color cleanliness of photovoltaic curtain walls, it is only necessary to perform simple processing on the surface glass, such as processing into a concave condenser array and other methods to increase the efficiency of sunlight utilization, and slow down the color difference by increasing the optical path and light reflection, so as to basically meet the environmental requirements for the color cleanliness of photovoltaic curtain walls. In contrast, existing large-size silicon-based photovoltaic cells often have color difference problems during long-term operation, making the wall look a bit "dirty" and difficult to meet the high standards of color cleanliness in the surrounding environment. Therefore, they are usually not used to build urban wall photovoltaic curtain walls. However, the photovoltaic curtain wall involved in the present invention does not have obvious problems in this regard, and silicon-based photovoltaic cells can be used, which has positive significance for the development of photovoltaic curtain walls.

[0009] 5. The present invention The intelligent photovoltaic curtain wall involved in the present invention has good temperature stability. The curtain wall adopts a double-layer glass structure to achieve an excellent temperature regulation effect, and can work in conjunction with systems such as central air conditioning to automatically maintain the constant temperature state of the wall. The vents between the photovoltaic modules promote effective heat exchange and prevent local overheating, thereby further improving the temperature stability of the curtain wall. Under extreme climatic conditions, such as overheating or overcooling, these vents can introduce external constant temperature gas, including cold air or heating provided by central air conditioning, to enhance the constant temperature performance of the curtain wall. This design has two significant advantages. First, it provides a photovoltaic curtain wall that can maintain a constant temperature, creating a comfortable living and living space indoors. Compared with traditional indoor air conditioning systems, the curtain wall of the present invention does not introduce particles such as PM2.5 when maintaining indoor temperature, so it does not affect the indoor air quality index. Especially when used for a long time in small spaces such as bedrooms, traditional air conditioners may cause odors in the room, affecting the health of residents. The curtain wall of the present invention only allows the constant temperature gas to circulate between the photovoltaic modules and does not enter the room, so it will not reduce the indoor air humidity, avoiding the problem of excessive dryness in the room, which is a common problem with traditional air-conditioning systems. An overly dry environment may induce skin problems or respiratory diseases. Secondly, when traditional air-conditioning systems are used in smaller spaces such as bedrooms or study rooms, the cold or heated air will blow directly onto the human body, causing discomfort. In contrast, the photovoltaic curtain wall of the present invention can avoid this situation and is beneficial to the physical and mental health of residents and staff. In addition, the photovoltaic power generation efficiency of the constant temperature photovoltaic curtain wall is higher, which can significantly improve the electrical efficiency of the photovoltaic curtain wall. At the same time, the photovoltaic modules and walls work in a constant temperature environment, avoiding the influence of extreme environments such as overheating or overcooling, which is beneficial to the anti-aging of the modules and can increase the service life of the curtain wall.

[0010] 6. The intelligent photovoltaic curtain wall involved in the present invention has excellent mechanical strength, so that it can still remain stable and safe in various harsh natural environments. In the construction of the photovoltaic curtain wall, the selection of the support body is crucial. Strong support components such as ceramic steel covered with a ceramic film protective layer on the surface can be used. This material not only has excellent strength and stability, but also can effectively resist the erosion of the external environment. In addition, reinforced concrete support structures can also be selected. This structure also has a strong support capacity and can withstand heavy loads and pressures. Under the support of these supports, the glass layer on the surface of the photovoltaic module can provide additional protection, so that the entire photovoltaic curtain wall can effectively resist the damage of natural disasters such as strong winds, heavy rains, and earthquakes. This design not only ensures the structural safety of the curtain wall, but also ensures the normal operation and power generation efficiency of the photovoltaic system. In particular, the ceramic film or concrete layer protective structure covered on the surface of the angle steel plays a vital role. This layer of protective structure greatly reduces the contact area between the supporting steel and acidified liquids such as air and rainwater, thereby effectively slowing down the corrosion process of the steel. Due to the presence of this protective layer, the steel will not be directly exposed to sunlight or air, which not only slows down the corrosion rate of the steel, but also improves the corrosion resistance and aging resistance of the support. In this way, the service life of the entire photovoltaic curtain wall is significantly improved, ensuring long-term stability and reliability. Therefore, the invented intelligent photovoltaic curtain wall not only improves the mechanical strength and durability of the curtain wall by adopting high-performance supports and effective protection measures, but also ensures the efficient operation and long-term stability of the photovoltaic system, providing a reliable solution for the green energy supply of buildings.

[0011] 7. The photovoltaic curtain wall involved in the present invention has the characteristics of easy installation and quick construction. Specifically, photovoltaic cells are cleverly encapsulated between two layers of glass to form photovoltaic modules. This design not only ensures the modular characteristics of the components, but also makes the modular manufacturing process more efficient. Modular photovoltaic modules greatly simplify the installation process, allowing construction workers to complete the installation work easily and quickly. In addition, fasteners for fixing the components are pre-designed between the supporting structure of the curtain wall and the photovoltaic modules. The presence of these fasteners further improves the convenience of installation and ensures that the photovoltaic module modules can be installed in place at a faster speed and higher efficiency. On the whole, the photovoltaic curtain wall of the present invention is not only innovative in design, but also shows significant installation advantages in practical applications, greatly improving construction efficiency and convenience.

[0012] 8. By adopting this innovative method to build an intelligent photovoltaic curtain wall, not only can the function of automatically adjusting the indoor light intensity be realized, but also the efficient use of photovoltaic power generation can be further realized. The introduction of this intelligent photovoltaic curtain wall makes the building itself have the characteristics of green energy, significantly reducing the building's dependence on traditional energy during operation. In this way, the carbon emissions of the building can be greatly reduced, which effectively supports the requirements of the national energy development strategy. In this way, the building not only performs well in energy conservation and emission reduction, but also contributes positively to the realization of the "dual carbon" goals proposed by the country, namely the carbon peak and carbon neutrality goals, and helps this grand goal to be realized as soon as possible.

DETAILED DESCRIPTION

[0017] The specific embodiments of the present invention can be illustrated by the following examples.

[0018] Example 1 A smart photovoltaic curtain wall for the south wall of a small residential villa building

[0019] The photovoltaic curtain wall system uses a sturdy and durable steel frame, and its surface is covered with a dense aluminum oxide protective film to ensure the durability and stability of the system. The size of the longitudinal aluminum alloy strips is 10×0.01×0.01 meters, and the size of the transverse aluminum alloy strips is 50×0.01×0.01 meters. These strips serve as the main supporting structure of the curtain wall to ensure the sturdiness of the entire system. The entire curtain wall is supported by 51 longitudinal aluminum alloy strips and 3 transverse aluminum alloy strips. These supporting structures are fastened to the steel frame and the inner support body, and the material is also aluminum alloy with an aluminum oxide protective film. This design not only ensures the structural stability of the curtain wall, but also ensures its corrosion resistance in harsh environments.

[0020] The photovoltaic cells used are LONGi Green Energy's Hi-MO 6 high-efficiency silicon monocrystalline HPBC cells, with a size of 10×990×2 mm. The upper and lower ends of the battery are equipped with concave slots made of aluminum alloy with a depth of 1 mm to facilitate the installation and fixation of battery components. The control system uses Siemens S7-1500 programmable PLC controller to ensure the intelligent and automated control of the curtain wall system, and implants a chip with AI function to remember user usage habits, optimize default settings, and provide a good user experience.

[0021] Control motors 4 and 5 are both AC fixed-speed motors from Oriental Motors, and their gears are cycloidal pinwheel gears from SIG Transmission with a diameter of 10 mm to ensure smooth and accurate motor operation. The dimensions of the battery storage box are 15×1000×200 mm, with a built-in bmm50 manipulator motor, the manipulator is a WLS-PHB-F200-T folding balance arm, and the internal guide rails of the storage box are stainless steel bars with a diameter of 1 mm to ensure smooth movement and precise positioning of the battery components.

[0022] The size of the photovoltaic module is 1000×1000×100 mm, and its inner and outer surfaces are made of high-purity ultra-white quartz glass insulating glass from Jiaxing Fulait Company, with a light transmittance of more than 92%. This high-transmittance glass not only ensures the aesthetics of the curtain wall, but also ensures that the photovoltaic module can fully absorb sunlight and improve power generation efficiency. The indoor surface is a plane, while the light-facing surface is a grating surface. The triangular pyramid of the grating surface is a right-angle triangular pyramid, with two acute angles of 30° and 60° respectively, a vertical cone depth of 1.5 mm, and a size of 1000×998×2 mm, in order to optimize the refraction and reflection of light and further improve power generation efficiency.

[0023] The guide rail is a 2mm diameter stainless steel spiral screw with a length of 10mm per section, ensuring smooth movement and precise positioning of the photovoltaic module. The battery storage box is located on one side of the photovoltaic module and is connected to the inside of the glass. The connection is sealed to prevent dust and moisture from entering, ensuring stable operation of the system.

[0024] There are air holes on both sides and the upper and lower sides of the photovoltaic modules for air circulation between modules to maintain the heat dissipation performance of the curtain wall system. The air holes on the top layer are connected to the central air conditioner to achieve constant temperature regulation of the photovoltaic curtain wall and ensure the efficient operation of the curtain wall system under various climatic conditions. In addition, in order to further improve the energy efficiency and practicality of the intelligent photovoltaic curtain wall, a number of innovative technologies have been incorporated. First of all, advanced heat conduction materials are used at the connection between the photovoltaic modules and the steel frame to ensure that the heat generated by the photovoltaic modules during operation can be quickly conducted to the outside through the frame, effectively avoiding overheating and extending the service life of the modules.

[0025] Considering the villa's need for energy self-sufficiency, we specially designed an energy storage system that uses high-performance lithium-ion battery packs to store excess electricity generated by the photovoltaic curtain wall for use in the villa at night or on cloudy days when there is insufficient light. The energy storage system is seamlessly connected to the villa's power management system to achieve intelligent scheduling and ensure maximum energy utilization.

[0026] In order to enhance the intelligent interactivity of the photovoltaic curtain wall, the Internet of Things (IoT) technology is integrated. Through built-in sensors and wireless communication modules, the curtain wall can monitor environmental parameters such as light intensity, temperature, humidity, etc. in real time, and automatically adjust the angle and inclination of the photovoltaic components based on these data to maximize the capture of light energy. At the same time, these data will also be uploaded to the user's smartphone or home energy management system, allowing users to remotely monitor the working status of the photovoltaic curtain wall and enjoy a more convenient and intelligent energy management experience.

[0027] In terms of safety performance, multiple protection measures are adopted. In addition to the conventional lightning protection design, intelligent overheat protection, short circuit protection and emergency power-off functions are also added to ensure that the photovoltaic curtain wall can respond quickly in extreme weather or emergencies to protect the system from damage.

[0028] We have also taken maintenance convenience into consideration. The photovoltaic curtain wall is designed to facilitate daily cleaning and maintenance. Users can use simple operations, such as using a remote control or mobile phone APP, to control the manipulator motor to drive the folding balance arm to automatically clean dust and debris on the surface of the photovoltaic module to maintain efficient light absorption.

[0029] Finally, in order to enhance the overall aesthetics of the villa, a lot of effort has also been put into the exterior design of the photovoltaic curtain wall. The modern minimalist style, combined with sophisticated craftsmanship, makes the curtain wall not only an efficient energy production device, but also a work of art that enhances the home style. Whether it is day or night, the intelligent photovoltaic curtain wall can add a harmonious beauty of technology and nature to the villa with its unique charm.

[0030] To sum up, this smart photovoltaic curtain wall not only represents the latest achievements of current green energy technology, but also is an active exploration and practice of future smart home life, aiming to bring a more environmentally friendly, intelligent and comfortable living experience to every user who pursues a high-quality life.

[0031] The above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
