Technical Field

[0002] Curtain walls, as a non-load-bearing exterior building envelope, are developing towards lightweight, versatile, safer, easier-to-construct, longer-lasting, and environmentally friendly energy conservation. Compared to the technical characteristics and common issues of traditional curtain walls (light pollution, thermal insulation, etc.), intelligent breathing curtain walls (double-skin curtain walls) offer greater potential for reducing energy consumption and improving efficiency.

[0003] However, there are three common problems with curtain walls on the market:

[0004] Problem 1: Existing intelligent breathing curtain wall systems mostly rely on external wiring for their power needs, rendering them inoperable in the event of a power outage. Problem 2: Most photovoltaic glass curtain walls lack the flexibility to adjust their deflection to the sun's angle of incidence, and their installation and fixing systems lack stability. Problem 3: Traditional green curtain walls typically utilize climbing plants for greening and sunshade, placing high demands on civil engineering loads and drainage, resulting in high ongoing maintenance costs. A lack of energy-saving awareness also contributes to the low economic efficiency of multi-layer curtain walls.

[0005] The numerous problems with existing curtain walls are driving the development of a new generation of building curtain wall systems that are intensive and sustainable. Therefore, standardized, green, intelligent, and integrated with building photovoltaics are needed.

[0061] like Figure 3 As shown, in this embodiment, an electrical box is provided in the exterior wall enclosure structure, and an inverter 16, a battery 17, a distribution box 18 and wires 19 are provided in the electrical box.

[0062] like Figure 6 As shown, in this embodiment, the external curtain wall rainwater collection and utilization system 2 includes a horizontal rainwater collection rod 21 and a vertical rainwater collection rod 22 located around the photovoltaic glass 13, and the photovoltaic glass 13 is located in a rectangular area surrounded by the horizontal rainwater collection rod 21 and the vertical rainwater collection rod 22, that is, the horizontal rainwater collection rod 21 and the vertical rainwater collection rod 22 are installed in the gap between the upper and lower and left and right sides of the photovoltaic glass; the horizontal rainwater collection rod 21 and the vertical rainwater collection rod 22 are fixedly connected to the vertical support rod 23 behind them.

[0063] like Figures 6-8As shown, in this embodiment, the external curtain wall rainwater collection and utilization system 2 also includes an internal rainwater filter 24 and a rainwater temporary storage tank 25 arranged in the external wall enclosure structure. The rainwater filter 24 is connected to the rainwater temporary storage tank 25 through a pipeline. The front sides of the horizontal rainwater collection rod 21 and the vertical rainwater collection rod 22 are respectively provided with a horizontal rainwater collection trough 20 and a vertical rainwater collection trough. The vertical rainwater collection trough is communicated with the horizontal rainwater collection trough, and a rainwater recovery pipe is connected between the end of the horizontal rainwater collection trough and the rainwater filter 24; the rainwater temporary storage tank 25 is connected to the drip irrigation pipe 28 located above the interlayer fern power generation system 4 and the plant curtain shading system 3 through a water pipe 27, and a water pump 26 is connected in series on the water pipe 27. The rainwater on the facade of the building glass curtain wall and the humidity in the high altitude of high-rise buildings pass through the horizontal rainwater collection trough 21; the horizontal rainwater collection trough 21 collects rainwater flowing down from the photovoltaic glass, and the rainwater on the vertical rainwater collection trough also flows into the horizontal rainwater collection trough 21. The rainwater in the horizontal rainwater collection trough 21 is drained to the rainwater filter 24 through the water pipes 27 at both ends. After filtering and purification by the rainwater filter device 24, it is stored in the rainwater temporary storage tank 25 for drip irrigation of plants, realizing water resource conservation and multi-functional utilization.

[0064] like Figures 9 and 10 As shown, in this embodiment, the plant curtain sunshade system 3 includes a plant folding curtain and a guide rail system 31 located above the plant folding curtain, and the plant folding curtain includes a plurality of metal frames 33 hinged at the ends into a chain shape, and the metal frames 33 are provided with elderberry plants 34 and a metal mesh 35 is provided in the middle of the metal frame 3, and a hook 331 is provided on the metal mesh.

[0065] like Figure 10 As shown, in this embodiment, the guide rail system 31 includes a guide rail 312 fixed by a mounting bracket 311. The guide rail 312 is fixed to the structural beam of the building. The top of each metal frame 33 is rotatably connected to a rotating shaft 32. The upper end of the rotating shaft 32 is provided with a guide wheel that cooperates with the guide rail 31. The guide rail 31 is provided with a driving mechanism for driving the plant folding curtain to extend and retract. Figures 12-15As shown, the drive mechanism includes a motor 314, a transmission box 313, and a synchronous belt.

The rotating shaft of the last metal frame is connected to the synchronous belt via a connector, so that the synchronous belt drives the last metal frame to move, thereby realizing the extension and retraction of the plant folding curtain. The plant curtain sunshade system 3 is similar to the smart electric curtain in the prior art, except that the curtain is replaced with a plant folding curtain composed of several metal frames 33. The motor 314 and transmission box 313 control the movement and extension of eight sets of metal frames 33. Hooks 331 are provided for hanging rootless safflower plants 34 that survive on moisture in the air. A drip irrigation pipe is provided at the top of the plant curtain sunshade system 3 for drip irrigation of safflower plants, and a drip irrigation pipe is provided at the bottom for drip irrigation of ferns 41. When the plant curtain sunshade system 3 is closed, the plant folding curtain folds and retracts to one side. When the light is too bright, the plant folding curtain is unfolded. This fully utilizes the greening sunshade effect, enhances the transpiration and evaporation effects of plants, and utilizes the energy conversion flow of greening sunshade to achieve environmental protection and energy saving. In the specific implementation process, the plant curtain sunshade system 3 can be controlled to automatically extend and retract by providing a temperature sensing system and a light sensing system. Both the temperature sensing system and the light sensing system are prior art, and their structures and principles will not be elaborated on in detail here.

[0066] like Figure 9 and Figure 11 As shown, in this embodiment, the interlayer fern power generation system 4 is located below the plant curtain sunshade system 3. This interlayer fern power generation system 4 includes ferns 41, which generate free electrons during photosynthesis, and a free electron collection system 42. The free electron collection system 42 comprises a plant planting trough 43 containing soil. A composite isolation layer 44 is provided between the soil and the building structure 45 at the bottom of the plant planting trough 43. Electrode plates 421 are inserted on the surface of the soil, located next to the fern 41. These electrodes 421 are connected to an electrical box via wires 422. The ferns are planted in a dedicated plant planting trough located between the inner and outer curtain walls and supported by a structural overhang beam. The planting soil in the planting trough is loose, water-retaining, and humus-rich. The electrodes are divided into positive and negative electrodes, each inserted into the soil surface of the plant planting trough. Free electrons generated by plant photosynthesis are collected by the positive and negative electrodes in the planting trough 2 and stored in a battery. The use of plant photosynthesis to generate electricity is an existing technology, and its principles and circuit structure will not be elaborated in detail here.

[0067] like Figure 16 、17 As shown, in this embodiment, the inner glass curtain wall and support system 5 includes upper and lower structural beams 51, the main building load-bearing structure, and a single-layer glass curtain wall. The single-layer glass curtain wall includes fixed glass sashes 53, inward-opening movable glass sashes 52, and a metal aluminum alloy window frame. The support system serves as the primary support structure for the inner glass curtain wall. The fixed glass windows are safety glass windows, primarily fixed 0.9 meters above the floor height. The inward-opening movable glass windows are fixed from the bottom of the structural beams to 0.9 meters above the floor height.

[0068] A working method of a variable multi-layer curtain wall system for composite photovoltaic and biomass power generation and vertical greening as described above, wherein the photovoltaic glass exterior curtain wall system utilizes light energy to generate electricity; the interlayer fern power generation system generates electricity by collecting free electrons produced by photosynthesis of ferns; the exterior curtain wall rainwater collection and utilization system collects rainwater on the exterior facade of the building's glass curtain wall for drip irrigation of plants; the plant curtain shading system creates a plant shading effect on the building's exterior curtain wall, reduces direct sunlight by lowering the building's heated surface, and thus reduces the building's energy consumption.

[0069] The photovoltaic glass of the photovoltaic glass curtain wall system is translucent. The main working principle of photovoltaic glass is to convert renewable solar energy into photoelectricity. Figures 18 to 29 As shown, the fixed photovoltaic glass 14 absorbs solar energy in a fixed direction. The photovoltaic glass blinds 11 can be opened and closed to adjust the heat between the glass curtain wall layers. The movable photovoltaic glass group adjusts the angle of the photovoltaic glass to follow the sun and efficiently absorbs sufficient solar energy. During the day, the photovoltaic glass 13 utilizes solar energy. The first step is to extend the cylinder horizontally outward by 300mm; the second step is to rotate the photovoltaic glass 13 15° in the vertical direction to maximize the absorption of solar energy from the optimal angle; the third step is to extend the cylinders on both sides of the photovoltaic glass 13 to different lengths, so as to achieve horizontal deflection of the photovoltaic glass 13, thereby achieving deflection following the trajectory of the sun's movement and maximizing the use of solar energy.

[0070] The main working principle of the exterior curtain wall rainwater collection and utilization system 2 is to collect rainwater on the facade of the building's glass curtain wall, and supply it to plants for drip irrigation through filtration and purification.

[0071] The ferns in the interspersed fern power generation system 4 will generate electrons with positive and negative charges during photosynthesis. A plurality of electrodes for collecting the electricity of the plants are set in the planting trough. The electricity generated by the plants during photosynthesis can be collected in time, and the electrical energy is stored in the battery through the controller. The controller is then used to discharge it to complete the floodlighting of the building facade.

[0072] The plant curtain shading system 3 controls the opening or closing state through real-time temperature and light sensing, creating a plant shading effect on the building's exterior curtain wall. It reduces direct sunlight by lowering the building's heated surface, thereby reducing building energy consumption, and drip-irrigates the plant curtains.

[0073] The inner glass curtain wall and support system 5 can regulate heat exchange between indoor and outdoor by manually opening the inner window sashes. The exterior wall enclosure structure is supported by the main load-bearing structure and comprises a multi-layer curtain wall system composed of multiple layers of curtain wall units. Vertical cavity members, supported by the main load-bearing structure, are located on both sides of the exterior wall enclosure structure. The left vertical cavity member primarily houses components such as the rainwater filter and rainwater temporary storage tank of the exterior curtain wall rainwater collection and utilization system 2; the right vertical cavity member primarily houses components such as electrical boxes.

[0074] like Figures 30-32 The figure shows the structure of the present invention in its nighttime, voice-activated state. Lights can be installed on the photovoltaic glass 13 of the photovoltaic glass exterior curtain wall system and controlled by a sound sensing system. Solar energy absorbed during the day provides electricity for building lights at night, transforming the photovoltaic glass 13 into a city landscape under the control of the sound sensing system. The sound sensing system also controls the telescopic length of the telescopic swing member 15 to achieve the desired effect. The circuit control components involved in the above functions are well-known in the art and are implemented using techniques known to those skilled in the art. They do not fall within the scope of protection of the present invention and are therefore not further elaborated upon here.

[0075] The utility model relates to a variable multi-layer curtain wall system of composite photovoltaic and bio-power generation and vertical greening. By utilizing photovoltaic power generation and fern photosynthesis to generate electricity, it can be used as temporary infrastructure to store the converted electrical energy in batteries, which can be conveniently used for the operation of the building itself or as a backup energy source, thus helping to enhance energy security. It increases the variability of the curtain wall and the green view rate of high-rise buildings, has the advantages of climate adaptation and breathability, and forms a breathable ecological building. It achieves the reduction of building energy consumption in all aspects, creates a net zero energy building, and better realizes urban renewal construction. It greatly reduces the heated surface of the building's outer skin and reduces building energy consumption. It can be used as a kind of urban micro-renewal to carry out the transformation of existing old buildings, update the building facade, and beautify the urban space interface landscape.

Therefore, only some numerical values ​​are disclosed in the present invention to illustrate the technical solution of the present invention. Furthermore, the numerical values ​​listed above should not be construed as limiting the scope of protection of the present invention.

[0077] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding).
