[0002] In the field of architecture, curtain walls are installed outside the building walls to protect the walls and provide decoration. With the advancement of technology, more and more high-rise buildings are using double-layer curtain wall structures. Compared with single-layer curtain wall structures, double-layer curtain wall structures can play a better role in noise reduction and temperature control. Double-layer curtain wall structures can still introduce outdoor natural wind into the room for ventilation in a noisy environment, which greatly reduces building energy consumption and improves the comfort of indoor personnel.

[0003] Chinese patent CN212805949U discloses a natural ventilation device for curtain walls of high-rise buildings, which relates to the current field of ventilation technology and includes a curtain wall module and two conveying mechanisms. The curtain wall module includes an outer curtain wall unit and an inner curtain wall unit arranged opposite to each other. The outer curtain wall unit is provided with an air inlet and an air outlet, and the inner curtain wall unit is provided with an exchange port. The projection of the exchange port toward the outer curtain wall unit falls between the air inlet and the air outlet. In the gap formed by the outer curtain wall unit and the inner curtain wall unit, an air inlet channel is formed between the air inlet and the exchange port, and an air exhaust channel is formed between the air outlet and the exchange port. Two conveying mechanisms are respectively arranged in the air inlet channel and the air exhaust channel.

[0004] In the above structure, a conveying mechanism is used to convey air to make the air flow. However, when this conveying mechanism is in operation, the air is blown from the air inlet to the curtain wall behind. Due to the obstruction of the curtain wall, turbulence will be formed at the air inlet. Due to the disturbance of the air, the air intake of the air inlet is affected.

At the same time, the turbulence at the air inlet is reduced, and the air intake effect is better. Since the wind at the high altitude of the building curtain wall is strong, when the air flow rate outside the curtain wall is high, the pressure is small. Therefore, the air will tend to flow in the direction of low pressure, so that the air in the outer curtain wall and the inner curtain wall will be discharged from the exhaust port. Since the back of the outer curtain wall is also provided with an air inlet guide cover, the air in the outer curtain wall and the inner curtain wall will be discharged from the exhaust port. The air inlet hood and the exhaust hood, the end with the larger diameter of the air inlet hood is fixed on the back of the outer curtain wall. After the air circulates in the air inlet hood, the diameter of the air inlet hood becomes smaller, so that the air flow speed in the air inlet hood is accelerated.

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 10 As shown, the present invention provides: a natural ventilation device for a curtain wall of a high-rise building, comprising an outer curtain wall 1, an energy storage device 15, an inner curtain wall 3 and a building body 4, wherein the inner curtain wall 3 is arranged at the front of the outer curtain wall 1, a ventilation channel is formed between the outer curtain wall 1 and the inner curtain wall 3, and the outer curtain wall 1 and the inner curtain wall 3 are sealed at the side, bottom and top by glass, an air inlet 11 is provided at the bottom of the outer curtain wall 1, and an air outlet 12 is provided at the top of the outer curtain wall 1. The outer curtain wall 1 is used as the outer protective structure of the high-rise building and is also the main component of the natural ventilation system. Through the air inlet 11 and the air outlet 12 provided therein, the outside air is guided to enter and circulate inside the building, forming a natural ventilation effect. Outdoor air is introduced through the air inlet 11 of the outer curtain wall 1, and the air flows in the channel, passes through the space between the inner curtain wall 3 and the building body 4, and is finally discharged from the air outlet 12 of the outer curtain wall 1. An air inlet guide hood 13 is fixed at the position where the back of the outer curtain wall 1 is connected to the air inlet 11, and an exhaust guide hood 14 is fixed at the position where the back of the outer curtain wall 1 is connected to the air outlet 12. The air inlet guide hood 13 and the exhaust guide hood 14 are designed with specific shapes to guide air to enter or leave the ventilation channel at the best angle and speed to reduce energy loss. A guide plate 17 is also provided at the bottom of the outer curtain wall 1 and the inner curtain wall 3. An energy collection device 16 is also provided in the air inlet guide hood 13 and the exhaust guide hood 14. The energy collection device 16 converts the energy of air flow into electrical energy. An insect guard plate 18 is also installed in the air inlet 11. The insect guard plate 18 is used to prevent flying insects from entering the channel between the outer curtain wall 1 and the inner curtain wall 3. The insect guard plate 18 prevents flying insects and other small creatures from entering the channel through its dense grid or special design to protect the indoor environment. In the design and manufacturing process, energy-saving materials and processes are used to reduce the energy consumption and carbon emissions of the device, which is in line with the concept of green building and sustainable development.

[0032] The diameter of one end of the air inlet shroud 13 is larger than the diameter of the other end of the air inlet shroud 13, and the end of the air inlet shroud 13 with a larger diameter is fixed to the back of the outer curtain wall 1. After the air circulates in the air inlet shroud 13, the diameter of the air inlet shroud 13 becomes smaller, so that the speed of the air flowing in the air inlet shroud 13 is accelerated. When the external air enters the shroud, its initial speed may be relatively low. However, as the air flows toward the end with a smaller diameter of the shroud, the air is forced to pass faster due to the reduction in cross-sectional area, thereby increasing the air flow rate entering the ventilation channel. A reasonable shroud design can also reduce turbulence and eddy currents during the air flow process, making the air flow smoother and more stable, and further improving the ventilation efficiency.

[0033] In this embodiment, by accelerating the air flow, the air inlet deflector 13 helps to quickly introduce more external air into the ventilation channel, thereby improving the ventilation efficiency of the entire natural ventilation system. Since the natural ventilation system relies on natural factors such as external wind and temperature difference to achieve ventilation, improving ventilation efficiency means that the building's dependence on mechanical ventilation systems can be reduced to a certain extent, thereby reducing energy consumption. A more efficient ventilation system helps to improve indoor air quality, reduce indoor pollutant concentrations, and improve living and working comfort.

[0034] The diameter of one end of the exhaust air deflector 14 is larger than the diameter of the other end of the exhaust air deflector 14, and the end of the exhaust air deflector 14 with a smaller diameter is fixed to the back of the outer curtain wall 1. When the air is discharged through the exhaust air deflector 14, the flow speed of the air in the exhaust air deflector 14 is accelerated. As the air flows toward the end with a smaller diameter of the air deflector, the air flow rate gradually increases due to the reduction of the cross-sectional area. This design helps to accelerate the exhaust process of air, reduce congestion and backflow at the exhaust port 12, and help reduce turbulence and eddy currents during the air flow process. This helps to maintain the stability of air flow, improve ventilation efficiency, and reduce noise.

[0035] In this embodiment, the exhaust air deflector 14 significantly improves the ventilation efficiency of the natural ventilation system by accelerating air exhaust and reducing turbulence, which helps to exhaust indoor hot air and pollutants more quickly and keep the indoor environment fresh and comfortable.

[0036] The guide plate 17 is an arc-shaped plate, and one end of the guide plate 17 extends upward. When the air enters the passage between the outer curtain wall 1 and the inner curtain wall 3, the turbulence formed at the air inlet guide cover 13 is reduced to affect the flow of air, so that the air flow is smoother. The guide plate 17 adopts an arc-shaped design, and this shape can guide the air flow more naturally. The arc-shaped plate surface can smoothly transition the direction of air flow and reduce the impact and turbulence generated when the air suddenly changes direction. This helps to reduce energy loss and improve the smoothness of air flow. When the air enters the passage between the outer curtain wall 1 and the inner curtain wall 3, a gradual transition space is provided, so that the air can smoothly change direction and accelerate the flow.

[0037] In this embodiment, the guide plate 17 guides the incoming air upward, reducing the impact of air turbulence at the air inlet guide cover 13, thereby improving the air flow effect.

[0038] The energy collection device 16 includes a turbine 166. Two turbines 166 are respectively arranged in the exhaust port 12 and the air inlet shroud 13 through supporting components, and the installation directions of the turbines 166 between the air inlet shroud 13 and the exhaust shroud 14 are opposite. When the air flows, the air blows the turbine 166 to rotate. The turbine 166 can assist the air flow and further accelerate the air flow. A second pulley 164 is fixed to one end of the turbine 166. When the air flows, whether it is entering or exhausting, it will blow the turbine 166 to rotate. This rotation not only generates electrical energy, but also assists the flow of air through the driving action of the blades of the turbine 166, further accelerating the flow rate of the air. This design realizes the dual utilization of energy, which not only collects wind energy but also enhances the ventilation effect.

[0039] The energy collection device 16 also includes a bracket 161 and a reversible motor 162. The reversible motor 162 is a special type of motor that can be operated as an electric motor (consuming electrical energy to generate mechanical energy) or as a generator (converting mechanical energy into electrical energy). In this energy collection device 16, it is mainly used as a generator. The first pulley 163 is fixed on the bracket 161, and the bracket 161 is arranged between the outer curtain wall 1 and the inner curtain wall 3. The reversible motor 162 is also provided with a first pulley 163. The first pulley 163 and the second pulley 164 are connected to each other through a belt. When the turbine 166 rotates, the turbine 166 rotates the second pulley 164 to drive the first pulley 163 to rotate the components inside the reversible motor 162, so that the reversible motor 162 can use the power of air flow to generate electricity and store it in the energy storage device 15. When the air flows, the turbine 166 starts to rotate under the action of wind force. This rotational motion is transmitted to the reversible motor 162 via a belt drive, causing its internal components (such as a rotor) to also start rotating. In this process, the reversible motor 162 operates as a generator, converting mechanical energy into electrical energy, which is then transported to the energy storage device 15 for storage.

[0040] In this embodiment, when the air flow rate outside the curtain wall is large, the pressure is small, therefore, the air will tend to flow in the direction of small pressure, so that the air in the outer curtain wall 1 and the inner curtain wall 3 will be discharged from the exhaust port 12. Since the back of the outer curtain wall 1 is also provided with an air inlet guide cover 13 and an exhaust guide cover 14, the end of the air inlet guide cover 13 with a large diameter is fixed to the back of the outer curtain wall 1. After the air circulates in the air inlet guide cover 13, the diameter of the air inlet guide cover 13 becomes smaller, so that the flow speed of the air in the air inlet guide cover 13 is accelerated. Similarly, the air flow rate will also be accelerated after passing through the exhaust guide cover 14, thereby rotating the turbine 166 to convert wind energy into electrical energy for storage, and the rotation of the turbine 166 will also assist in the flow of air.

[0041] The energy collection device 16 also includes two speed detection devices 165. The speed detection device 165 usually adopts a non-contact sensor (such as a photoelectric sensor, a Hall sensor, etc.) to calculate the speed by measuring the signal change when the turbine 166 blade passes a specific position. This measurement method is accurate and reliable, and will not cause any obstruction to the rotation of the turbine 166. The speed detection device 165 is respectively arranged in the air inlet guide cover 13 and the exhaust guide cover 14. The speed detection device 165 is used to detect the speed of the turbine 166. When the speed of the turbine 166 is too low, the reversible motor 162 uses electric drive to rotate the turbine 166, thereby compensating for power and accelerating the air flow. When the external wind is weak or the air flow speed is slow, the speed of the turbine 166 may be reduced to a certain extent, resulting in a decrease in energy collection efficiency. At this time, the speed detection device 165 will capture this change in time and send a signal to the control system. After the control system receives the signal that the speed is too low, it will start the motor mode of the reversible motor 162. The motor will consume the stored electricity or the electricity provided externally to drive the turbine 166 to rotate, thereby performing power compensation. This compensation mechanism can ensure that the turbine 166 can maintain a certain rotation speed even under low wind speed conditions, thereby maintaining or accelerating the air flow speed and improving energy collection efficiency.

[0042] In this embodiment, when the external wind force is too small, the speed detection device 165 detects the speed of the turbine 166. When the speed of the turbine 166 is low, the reversible motor 162 can be automatically started. The reversible motor 162 rotates the first pulley 163, and then rotates the second pulley 164, so that the turbine 166 rotates, assists the air flow, and makes the indoor air flow for ventilation. The device does not need an external power supply, which plays a role in saving energy. By introducing the speed detection device 165 and the adaptive power compensation mechanism, the energy collection device 16 realizes intelligent management. It can not only automatically adjust the working mode (generating electricity or driving the turbine 166) according to external conditions, but also perform power compensation when necessary to ensure that the system always operates in the optimal state. This design also has significant advantages in energy saving and environmental protection. When the external wind force is sufficient, the system mainly relies on natural wind to drive the turbine 166 to rotate and generate electricity; when the wind force is insufficient, it consumes a small amount of electricity to drive the turbine 166 to rotate to maintain air flow and energy collection. This way of allocating resources on demand effectively reduces energy consumption and emissions.

[0043] A photovoltaic panel 2 for converting light energy into electrical energy is also provided on the top of the exterior of the outer curtain wall 1. The photovoltaic panel 2 is provided on the top of the exterior of the outer curtain wall 1, and its main function is to convert solar energy into electrical energy. This conversion method is clean and renewable, and helps to reduce dependence on traditional energy. The electrical energy converted by the photovoltaic panel 2 is stored in an energy storage device 15. The energy storage device 15 includes a protective box 151 and an energy storage battery 152 for storing electrical energy. The protective box 151 is fixed to the back of the outer curtain wall 1, and the energy storage battery 152 is fixed in the protective box 151. The protective box 151 is also provided with a control circuit board 153 for controlling power distribution.

[0044] An exchange port 31 is also provided on the inner curtain wall 3. The inner curtain wall 3 is installed outside the building body 4, and a support assembly 5 is fixed between the inner curtain wall 3 and the building body 4. The support assembly 5 is used to fix the inner curtain wall 3 and the building body 4 to each other.

[0045] An opening and closing assembly 6 is also provided on the air inlet guide cover 13, the air exhaust guide cover 14 and the inner curtain wall 3. The opening and closing assembly 6 is used to close each air outlet. The opening and closing assembly 6 includes an electric cylinder 61, a fixing member 62 and a baffle 63. The baffle 63 is installed on the piston end of the electric cylinder 61. The electric cylinder 61 is used to drive the two baffles 63 to move closer to or apart from each other. The baffle 63 is used to close the air outlet, and the fixing member 62 is used to fix the electric cylinder 61. The fixing member 62 is fixed to the curtain wall.

[0046] Working principle: When in use, the inner curtain wall 3 is installed on the outside of the building body 4 and fixed by the support assembly 5. Since the building has higher floors, the air flow at the upper floors is greater than that at the lower floors. Therefore, the pressure at the higher floors is lower, and the air will tend to flow in the direction of lower pressure, so that the air in the outer curtain wall 1 and the inner curtain wall 3 will be discharged from the exhaust port 12. Since the back of the outer curtain wall 1 is also provided with an air inlet guide cover 13 and an exhaust guide cover 14, the end with a larger diameter of the air inlet guide cover 13 is fixed on the back of the outer curtain wall 1, and the air in the air inlet guide cover 1 3, since the diameter of the air inlet guide cover 13 becomes smaller, the flow speed of the air in the air inlet guide cover 13 is accelerated. Similarly, the flow speed of the air after passing through the exhaust guide cover 14 will also be accelerated, thereby causing the turbine 166 to rotate, the turbine 166 causes the second pulley 164 to rotate, the second pulley 164 causes the first pulley 163 to rotate through the belt, and the first pulley 163 causes the reversible motor 162 to rotate to convert wind energy into electrical energy and store it in the energy storage battery 152, and the photovoltaic panel 2 can convert light energy into electrical energy and store it in the energy storage battery 152, and the rotation of the turbine 166 also The air flow is assisted, and the guide plate 17 guides the incoming air upward, reduces the turbulence of the air at the air inlet guide cover 13, and ensures smooth air flow. When the external wind force is too small, the speed detection device 165 detects the speed of the turbine 166. When the speed of the turbine 166 is low, the reversible motor 162 can be automatically started, and the reversible motor 162 rotates the first pulley 163, and then rotates the second pulley 164, so that the turbine 166 rotates, assisting the air flow, so that the indoor air flows for ventilation, and the device does not need an external power supply. The utility model can save energy. If the external wind is too strong, the electric cylinder 61 can be started, and the electric cylinder 61 can move the baffle 63. The two baffles 63 can close each air outlet to prevent the wind from being too strong and affecting the people in the building. If there is no wind outside, the outer curtain wall 1 under the sunlight, the air temperature in the channels of the outer curtain wall 1 and the inner curtain wall 3 rises and naturally floats up, forming a chimney effect of air flow from bottom to top, realizing the function of automatic exhaust. At the same time, an insect baffle 18 is arranged in the air inlet 11, and the insect baffle 18 can prevent various flying insects from entering the curtain wall.

[0047] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
