Description

Technical Field

[0001] The present invention belongs to the technical field of green buildings, and particularly relates to a passive energy-saving building facade sine-wave diversion peripheral protection system. Background Art

[0002] For large-scale over-limit buildings (such as super high-rise buildings and special-shaped structure buildings), they often have characteristics such as large site area, high floors, and obvious setbacks around, which provide a focus for designers to study the energy-saving scenarios of their ultra-high facades and heterogeneous facades. However, traditional building facades often only pay attention to the control of the site wind direction, such as avoiding the generation of windless areas, appropriately controlling the wind speed and wind feeling requirements at the pedestrian height (1.5 m), and avoiding excessive wind pressure differences on the doors, windows and curtain walls, which may affect the airtightness, etc.

[0003] Specifically, as Figure 7 shown, the traditional facade buildings have the following deficiencies in wind power recovery: 1. The natural wind field is disordered, the wind direction shows a disordered and scattered state, and mainly acts on the building curtain wall, presenting in the form of wind pressure, which results in relatively low wind power capture efficiency; 2. The installation method of the wind power capture device is relatively limited, and it needs to be strictly perpendicular to the horizontal plane and the outer surface of the curtain wall. Therefore, it can only capture the wind power in a single direction and lacks flexibility; 3. The wind power recovery system completely depends on windy weather, and the flat and consistent design of the building outer surface makes the wind well effect unable to be effectively utilized; 4. The wind direction is easily disturbed by external factors and scattered, resulting in the gradual weakening of the wind power during the diversion process, further reducing the wind power recovery efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a passive energy-saving building facade sine-wave diversion peripheral protection system, which solves the technical problems existing in the prior art, such as the disorder of the natural wind field leading to low wind power capture efficiency, the limited installation direction of the capture device and only being able to capture a single wind direction, relying on natural wind and unable to effectively utilize the wind well effect, and the easy dispersion of the wind direction.

[0005] The present invention discloses a passive energy-saving building facade sine-wave diversion peripheral protection system, including: An outer facade assembly, installed outside the floor slab, including sine-wave diversion mechanisms and an outer curtain wall alternately arranged from top to bottom. The sine-wave diversion mechanism has a wavy ridge structure and has an accommodation cavity inside; A wind turbine, installed in the accommodation cavity; Wherein, air inlets are opened at the wave troughs of the upper top surface and / or the wave peaks of the lower bottom surface of the sine-wave diversion mechanism, and air permeable holes are opened on the outer surface of the sine-wave diversion mechanism.

[0006] This application can converge, guide, and discharge the natural wind field, thereby forming an effective eddy current and converging the wind field at the air intake. It can capture more wind energy resources under the same wind conditions, significantly improving the wind energy capture efficiency. It can also adapt to airflows in different directions, enabling the wind turbine unit to be installed in a concealed manner without affecting the building facade effect. There is no need to follow the fixed installation mode perpendicular to the horizontal direction. It can be flexibly arranged according to the actual wind direction at the installation location, and the system can better adapt to complex and changeable wind direction conditions, greatly improving the stability and reliability of wind energy utilization. Moreover, even in windless weather, the system can continuously generate a certain amount of airflow power to drive the wind turbine unit to operate, effectively making up for the problem of insufficient wind power and ensuring the continuity and stability of the building's energy supply.

[0007] Based on the above technical solutions, the solution of this application can also be improved as follows: Preferably, it further includes: The inner curtain wall is provided between the floors one by one, and together with the outer facade assembly and two adjacent floors, it encloses an interlayer air duct, and the interlayer air duct is communicated with the adjacent accommodation cavity; Among them, a plurality of fresh air inlets are opened on the inner curtain wall, and an opening and closing plate is installed at the fresh air inlet, and the opening and closing plate is used to open or close the fresh air inlet; With this solution, the fresh air inlets can be naturally hidden in the sine wave diversion mechanism without any adverse effects on the building's shape, aesthetic feeling, and ventilation effect, thus achieving the unity of function and beauty.

[0008] Preferably, the fresh air inlets are arranged in the upper area of the inner curtain wall and are used to be hidden in the ceiling space; With this solution, it not only meets the functional requirements but also maintains the integrity of the indoor interface without damaging the indoor beauty.

[0009] Preferably, it further includes: The secondary structure is arranged between the outer facade assembly and the inner curtain wall; With this solution, it plays a role in load-bearing connection and can effectively transfer the wind load borne by the outer facade assembly to the inner curtain wall and the building's main structure, thereby enhancing the integrity and stability of the entire building structure.

[0010] Preferably, the sine wave diversion mechanism is composed of a plurality of buckling smooth gradual change bodies connected end to end in sequence; With this solution, it is convenient for the installation and layout of the sine wave diversion mechanism and the wind turbine unit.

[0011] Preferably, the buckling smooth gradual change body includes: A plurality of grille supports are installed laterally at intervals outside the floor; A plurality of buckling rays are installed on the outer edge of the grille support and are arranged vertically at intervals; Multiple sinusoidal curved panels are installed on the grille support, and buckling rays are provided between adjacent sinusoidal curved panels. With this solution, stable support is provided, overall stability is ensured, structural strength is enhanced, the overall weight is reduced, and construction and installation are facilitated.

[0012] Preferably, the sinusoidal curved panel is divided into multiple reference sinusoidal flow guiding plates by eight reference lines; Among them, the eight reference lines are, in sequence: the outer contour line of the floor slab, the glass surface positioning line, the glass mullion baseline, the aluminum plate mullion normal line, the mullion foundation line, the vertical joint of the aluminum plate, the horizontal joint double line of the aluminum plate, and the aluminum plate forming surface baseline. With this solution, the size is relatively small, the weight is light, which is convenient for transportation, installation and disassembly; and during later maintenance, the problematic reference sinusoidal flow guiding plate can be replaced separately, thereby reducing the maintenance cost and workload.

[0013] Preferably, it further includes: A layer-connected rigid support is provided between the exterior curtain wall and the floor slab. With this solution, the structural stability is enhanced, the wind resistance performance is improved, and the flatness is ensured.

[0014] Preferably, the wind turbine is composed of multiple pairs of micro wind impeller mechanisms, and the micro wind turbines are installed on the vertical section of the grille support and form a one-to-many combination with the air intake port.

It can capture more wind energy resources under the same wind conditions, significantly improving the wind energy capture efficiency; 2. The present application utilizes a sine-wave air diversion mechanism that can adapt to airflows in different directions and guide the airflows to the wind turbine.

It can be flexibly arranged according to the actual wind direction at the installation location, enabling the system to better adapt to complex and variable wind direction conditions, greatly improving the stability and reliability of wind energy utilization.

[0017] 3. When there is no wind in the present application, due to the uneven heat absorption of different parts of the sine-wave air diversion mechanism and the outer curtain wall under sunlight irradiation, local temperature field differences are caused, which in turn generate upward airflows. The design of imitating waves and preventing wind valleys on the outer surface further enhances the effect of these upward airflows. Therefore, even in windless weather, the system can continuously generate a certain amount of airflow power to drive the wind turbine to operate, effectively making up for the problem of insufficient wind power and ensuring the continuity and stability of the building's energy supply.

Detailed implementation manners

[0020] The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0021] First of all, it should be noted that some orientation words involved in the following description to clearly illustrate the technical solution of the present invention, such as the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are all the meanings analogously possessed according to the normal orientations of the components in the string wave diversion outer enclosure system of the passive energy-saving building facade. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention.

[0022] In this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] To better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings of the specification and specific implementation manners.

[0024] Embodiment: As Figure 1 shown, the embodiment of the present application discloses a string wave diversion outer enclosure system for a passive energy-saving building facade. The system aims to effectively utilize a large curtain wall or a buckling facade, and naturally change the wind pressure impact angle of the building outline through bionic design, thereby forming a steady-state outdoor wind pressure. In this way, it can not only weaken the strong wind feeling at the pedestrian height, but also increase the possibility of the outer facade to withstand and capture the wind field, realizing the effective utilization of wind energy and building energy conservation; its specific structure includes: an outer facade assembly 1 and a wind turbine generator set 2.

[0025] The outer facade assembly 1 is installed on the outside of the floor slab 7 and includes a sine-wave air guiding mechanism 11 and an exterior curtain wall 12 that are alternately arranged from top to bottom. The sine-wave air guiding mechanism 11 has an overall wavy ridge structure and has an accommodation cavity 1101 inside it.

[0026] Specifically, the sine-wave air guiding mechanism 11 adopts a bionic design, and its design inspiration is similar to that of the Yardang landform. The unique terrain features of the Yardang landform can effectively guide and change the air flow direction. By simulating this terrain feature, the sine-wave air guiding mechanism 11 realizes the guidance and regulation of the air flow around the building.

[0027] Among them, air intake ports 1102 are provided at the wave troughs of the upper top surface and / or the wave peaks of the lower bottom surface of the sine-wave air guiding mechanism 11, and air permeation holes 1103 are provided on the outer surface of the sine-wave air guiding mechanism 11.

[0028] The wind turbine 2 is installed in the accommodation cavity 1101 and is used to convert wind energy into electrical energy, so as to provide partial power support for the building and achieve the purpose of energy conservation and emission reduction.

[0029] It should be noted that as Figure 5 shown, the sine-wave air guiding mechanism 11 is wavy, so the concave areas on its upper top surface and lower bottom surface form a diversion groove structure, which plays a role in guiding and concentrating the air flow. By opening the air intake port 1102 at the center of this area, it can ensure the effective utilization of wind energy.

[0030] Through the above settings, the present application has the following technical effects: First, relying on the wavy ridge structure of the sine-wave air guiding mechanism 11, the natural wind field can be converged, guided and discharged, thus forming an effective eddy current, and converging the wind field at the air intake port 1102. Under the same wind force conditions, more wind energy resources can be captured, significantly improving the wind energy capture efficiency.

[0031] Second, since the sine-wave air guiding mechanism 11 can adapt to air flows in different directions and guide the air flow to the wind turbine 2, the wind turbine 2 can be installed in a hidden manner, without affecting the building facade effect, and there is no need to follow the fixed installation mode perpendicular to the horizontal direction. It can be flexibly arranged according to the actual wind direction at the installation location, and the system can better adapt to complex and changeable wind direction conditions, greatly improving the stability and reliability of wind energy utilization.

[0032] III. When there is no wind, due to the uneven heat absorption of different parts of the chord wave flow guiding mechanism 11 and the outer curtain wall 12 under sunlight irradiation, local temperature field differences are caused, which in turn generate upward airflows. Then, by using the design of the wave-like and wind-proof valleys on the outer surface, the effect of such upward airflows is further enhanced. Therefore, even in windless weather, the system can continuously generate a certain amount of airflow power to drive the wind turbine 2 to operate, effectively making up for the problem of insufficient wind power and ensuring the continuity and stability of the building energy supply.

[0033] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 shown, it further includes: an inner curtain wall 3, which is respectively arranged between the floor slabs 7, and together with the outer facade assembly 1 and two adjacent floor slabs 7, encloses an interlayer air duct 4. The interlayer air duct 4 is communicated with the adjacent accommodation cavity 1101, and each interlayer air duct 4 is arranged within each floor and does not affect each other.

[0034] Among them, a plurality of fresh air inlets 31 are opened on the inner curtain wall 3, and an opening and closing plate 32 is installed at the fresh air inlet 31. The opening and closing plate 32 is used to open or close the fresh air inlet 31.

[0035] Through the above settings, the fresh air inlets 31 can be naturally hidden in the chord wave flow guiding mechanism 11 without any adverse effects on the shape, aesthetic feeling and ventilation effect of the building, thus realizing the unity of function and beauty.

[0036] Based on the above embodiments, as Figure 4 shown, the fresh air inlets 31 are arranged in the upper area of the inner curtain wall 3 and are used to be hidden in the ceiling space, so as to not only meet the functional requirements but also maintain the integrity of the indoor interface without damaging the indoor aesthetics.

[0037] In some embodiments, such as Figure 1 shown, it further includes: a secondary structure 5, which is arranged between the outer facade assembly 1 and the inner curtain wall 3 and is used to play a role of load-bearing connection, and can effectively transfer the wind load borne by the outer facade assembly 1 to the inner curtain wall 3 and the building main structure, thereby enhancing the integrity and stability of the entire building structure.

[0038] In some embodiments, the chord wave flow guiding mechanism 11 is composed of a plurality of buckling smooth gradient bodies 111 connected end to end in sequence; it takes bionic wave crests, wave valleys, natural frequencies and bidirectional amplitudes as basic elements to realize the orderly division of the large-span facade, which not only helps to reasonably guide the flow of air on the building facade to form good airflow organization, but also facilitates the installation and layout of the chord wave flow guiding mechanism 11 and the wind turbine 2.

[0039] Based on the above embodiments, as Figure 2As shown in the figure, the buckling smooth transition body 111 includes: a plurality of grid supports 1111, several buckling rays 1112, and multiple chord wave curved panels 1113. The specific settings are as follows: The plurality of grid supports 1111 are horizontally spaced and installed outside the floor slab 7. As the basic support structure, they provide a stable installation platform for the subsequently installed buckling rays 1112 and chord wave curved panels 1113. Moreover, the horizontally spaced installation method can reduce the overall weight while ensuring the structural strength, and form a breathable wall structure, realizing the connection between the accommodation cavity 1101 and the interlayer air duct 4, and can orderly guide the positive and negative airflows, reducing the disordered wind pressure phenomenon of sudden cooling and heating. Several buckling rays 1112 are installed on the outer edge of the grid supports 1111 and are vertically spaced. The buckling rays 1112 are the outermost contours of the three-dimensional facade body, playing a role in supporting the chord wave curved panels 1113, enhancing the structural strength and stability, and improving the bearing capacity of external wind loads and other loads. Multiple chord wave curved panels 1113 are installed on the grid supports 1111, and buckling rays 1112 are provided between adjacent chord wave curved panels 1113, which helps to guide the air to flow along a specific path, realizing functions such as air collection and diversion.

[0040] Through the above structural design of the buckling smooth transition body 111, firm support is provided, overall stability is guaranteed, structural strength is enhanced, the overall weight is reduced, and construction and installation are facilitated.

[0041] Based on the above embodiments, as Figure 2 shown in the figure, the chord wave curved panel 1113 is divided into multiple reference chord wave diversion plates 11131 by eight reference lines. Among them, the eight reference lines are in turn: the outer contour line of the floor slab, the glass surface positioning line, the glass mullion baseline, the aluminum plate mullion normal line, the mullion foundation line, the vertical joint of the aluminum plate, the double horizontal joint of the aluminum plate, and the aluminum plate forming surface baseline.

[0042] By dividing the chord wave curved panel 1113 into multiple reference chord wave diversion plates 11131, their sizes can be relatively small and the weights can be light, thus facilitating transportation, installation, and disassembly; and during later maintenance, the problematic reference chord wave diversion plates 11131 can also be replaced individually, thereby reducing the maintenance cost and workload.

[0043] In some embodiments, as Figure 1 and Figure 3 shown in the figure, it further includes: a layer-connected rigid support 6, which is provided between the exterior curtain wall 12 and the floor slab 7 and has the following effects: I. Enhance structural stability: It can effectively transfer the loads received by the external curtain wall 12 to the floor slab 7 and then disperse them to the entire building structure, avoiding deformation or damage of the external curtain wall 12 due to excessive local stress and enhancing the stability of the entire building structure; II. Improve wind resistance performance: Provide additional lateral support for the external curtain wall 12, reduce the swaying and displacement of the external curtain wall 12 under the action of wind loads, and improve the wind resistance performance of the building; III. Ensure flatness: It can limit the deformation of the external curtain wall 12, ensure that the external curtain wall 12 remains flat during long-term use, avoid phenomena such as unevenness, distortion, etc., and maintain the aesthetic appearance of the building.

[0044] In some embodiments, the wind turbine 2 is composed of multiple pairs of micro wind impeller mechanisms. The micro wind turbines are installed on the vertical section of the grid support 1111 and form a one-to-many combination with the air intake port 1102.

[0045] It should be noted that the grid support 1111 has an "F" - shaped structure, including a vertical section and a horizontal section; one side of the vertical section is connected to the floor slab 7, and the other side is provided with a horizontal section; thus, by installing the micro wind turbine on the vertical section, stable support can be provided for the turbine, avoiding the additional increase of a complex support system and reducing the installation cost and difficulty.

[0046] Through the one-to-many combination, the risks in the process of wind energy utilization can be dispersed. When one pair or several pairs of turbines fail or are affected by external factors such as debris blockage, strong wind damage, etc. and cannot operate normally, other turbines can still continue to operate, ensuring the continuity of the overall power generation function of the wind turbine 2 and improving the reliability and stability of the system.

[0047] In some embodiments, as Figure 1 shown, the external curtain wall 12 includes: a plurality of curtain wall mullions 121 and a plurality of curtain wall panels 122; among them, the plurality of curtain wall mullions 121 are vertically arranged and horizontally spaced; the plurality of curtain wall panels 122 are respectively arranged between the curtain wall mullions 121.

[0048] Preferably, as Figure 4 shown, the top and / or bottom of the vertical section of the buckling smooth transition body 111 has a horizontal section for abutting against the curtain wall mullion 121, thereby increasing the contact area, improving the connection firmness, and enabling the air intake port 1102 to be hidden, thus improving the aesthetic appearance.

[0049] First, through the mutual cooperation of the curtain wall mullion 121 and the curtain wall panel 122, a complete frame structure is jointly formed, which has good integrity and stiffness, can effectively transfer external loads to the building main structure, thereby dispersing stress and improving the load - bearing capacity of the external curtain wall 12.

[0050] Secondly, the mullions 121 of the curtain wall can be prefabricated and installed first to form a basic frame structure, and then the curtain wall panels 122 can be installed one by one between the mullions. This modular construction method can reduce the workload and difficulty of on-site construction, and improve the construction speed and quality.

[0051] Finally, since the curtain wall panels 122 are independently arranged, if a certain panel is damaged or needs to be replaced, it can be easily disassembled and installed without affecting the normal use of other parts.

[0052] The following is a further description of this application: During the normal working process, due to the wind pressure difference between the outside of the air intake port 1102 and the ventilation hole 1103, the air flow will enter the accommodation cavity 1101 through the air intake port 1102, and then flow out of the accommodation cavity 1101 through the ventilation hole 1103, thereby forming an air flow with a certain flow rate and pressure, so as to drive the wind turbine 2 to operate and generate electricity, converting wind energy into electrical energy.

[0053] When the indoor air quality is poor, as Figure 4 shown, open the opening and closing plate 32 and open the fresh air inlet 31. Due to the wind pressure difference between the indoor and the air intake port 1102, the outdoor air flow can enter the indoor through the air intake port 1102, the accommodation cavity 1101, the interlayer air duct 4 and the fresh air inlet 31 in sequence; or, the fresh air system can also be opened to suck the indoor air, making the indoor air flow form a negative pressure cycle, thereby improving the indoor wind feeling. Then the indoor air flows out to the outside through the fresh air inlet 31, the interlayer air duct 4, the accommodation cavity 1101 and the ventilation hole 1103 in sequence.

[0054] The installation process of this application is as follows: I. Install the grille support 1111 outside the floor slab 7. The structure of the grille support 1111 is confirmed by the sectional dimensions of the building model at this location, and the secondary structure 5 is reserved within the height of the outer curtain wall 12; II. Connect the processed buckling rays 1112 to the outermost side of the grille support 1111, and a number of buckling rays 1112 are fixed to the horizontal ends of the corresponding grille supports 1111 in sequence; III. Divide a plurality of reference chord wave flow guiding plates 11131 in sequence according to the reference line, and fix them on the buckling rays 1112 according to four points coplanar. The chord wave flow guiding mechanism 11 with a wavy ridge structure is enclosed by the reference chord wave flow guiding plates 11131; IV. Install the wind turbine 2 on one side of each floor slab 7, and fix the micro wind turbine to the vertical section of the grille support 1111, and make it in the same plane as the buckling ray 1112 on one side of the air intake port 1102; V. Install the exterior curtain wall 12 on each floor, using the floor slab 7 as the support, and install it in sections to complete the overall enclosure of the exterior curtain wall 12 and the sine wave flow guiding mechanism 11; VI. Ensure the width of the interlayer air duct 4, then install the interior curtain wall 3, and check the position of the fresh air inlet 31 at the top to ensure its normal use.
