Description

Technical Field

[0001] This invention relates to the field of wind-resistant building technology, specifically to a multifunctional wind barrier based on a layered blocking variable stiffness structure. Background Technology

[0002] The design principle of wind barriers is primarily to prevent the adverse effects of wind on specific areas (such as roads, bridges, and buildings), and to improve the safety and stability of these areas under strong wind conditions. Traditional wind barriers mostly employ structures with fixed stiffness, unable to automatically adjust their protective effect according to wind strength. Therefore, developing a wind barrier capable of adaptively adjusting stiffness has become an urgent need in the industry. Secondly, layered variable stiffness structures are adaptive structures that can adjust the overall structural stiffness by changing the density of the internal material stacking. This structure can adjust its stiffness as needed when subjected to external forces to better adapt to changes in the external environment. Introducing layered variable stiffness structures into wind barrier design can enhance the wind barrier's adaptability and protective effect. Furthermore, with the continuous development of renewable energy technologies, the utilization of wind energy is receiving increasing attention. As a structure exposed to the natural environment for extended periods, wind barriers have the potential to collect wind energy. By integrating wind energy harvesting devices, wind barriers can not only provide protection but also convert wind energy into renewable energy sources such as electricity, achieving efficient energy utilization. Therefore, this application proposes a multifunctional wind barrier based on a layered variable stiffness structure. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a multifunctional wind barrier based on a layered blocking variable stiffness structure. It features the advantage that, based on the principle of layered blocking variable stiffness, the blade stiffness of the wind barrier can be dynamically controlled by a single negative pressure source, thereby controlling its air permeability. This allows it to adjust its posture appropriately under different incoming flows, achieving reasonable flow control. It solves the problems of traditional wind barriers, such as their single form and function, fixed shape and air permeability, and the aging, wear, and jamming issues of traditional mechanical wind barriers.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional wind barrier based on a layered blocking variable stiffness structure, comprising a support frame and a clamping structure. Variable stiffness blades are movably connected to the upper part of the support frame. The variable stiffness blades are internally provided with a waterproof layer, an elastic sheet, and a filler. The filler shape includes layered, granular, and fibrous forms. A monitoring sensor is fixedly installed on the top right side of the variable stiffness blades. The wind barrier is controlled by a negative pressure source, which is located inside the clamping structure. The variable stiffness blades are controlled by a negative pressure source of a negative pressure compressor. Multiple variable stiffness blades are connected in parallel to a negative pressure compressor. The negative pressure compressor is connected to a vacuum solenoid valve, which controls the negative pressure.

[0005] Preferably, the main structure of the wind barrier is a support frame, which provides stability and support for the entire wind barrier. Above the support frame, the movable connection design allows the variable stiffness blades to be adjusted according to changes in wind speed and direction.

[0006] Preferably, the variable stiffness blade is a key component of the wind barrier, enabling it to achieve variable stiffness for layered blocking. This design allows the wind barrier to automatically adjust its stiffness according to the wind force, thereby improving the protective effect and service life of the wind barrier.

[0007] Preferably, the variable stiffness blade is internally provided with a waterproof layer, an elastic sheet, and a filler. The waterproof layer can protect the wind barrier from rainwater erosion and improve its service life. The elastic sheet provides good elasticity and resilience, which helps to maintain the shape and stability of the wind barrier. The filler can increase the density and stability of the wind barrier and improve its wind resistance performance.

[0008] Compared with the prior art, the present invention provides a multifunctional wind barrier based on a layered blocking variable stiffness structure, which has the following beneficial effects:

[0009] 1. This multifunctional wind barrier based on a layered blocking variable stiffness structure features movable frames and components of variable stiffness blades that adaptively adjust according to wind intensity and direction. This adjustment is achieved through the layered blocking variable stiffness structure, which can change the stiffness of the variable stiffness blades as needed to better resist wind. When the wind force increases, the stiffness of the variable stiffness blades increases; when the wind force is too strong, the stiffness can be reduced to allow airflow and dissipate energy, reducing the impact on the structure and providing stronger protection. When the wind force decreases, the stiffness will decrease accordingly to reduce interference with the surrounding environment. The blade stiffness of the wind barrier can be dynamically controlled by a single negative pressure source, thereby controlling its permeability and allowing it to adjust its attitude appropriately under different incoming flows, achieving reasonable flow control.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-6 A multifunctional wind barrier based on a layered blocking variable stiffness structure includes a support frame 1 and a clamping structure 101. Variable stiffness blades 2 are movably connected to the upper part of the support frame 1. The variable stiffness blades 2 have a waterproof layer 201, an elastic sheet 202, and a filler 203 inside. The filler 203 has a layered, granular, and fibrous shape. A monitoring sensor 3 is fixedly installed on the top right side of the variable stiffness blades 2. The wind barrier is controlled by a negative pressure source, which is located inside the clamping structure 101. The variable stiffness blades 2 are controlled by a negative pressure source of a negative pressure compressor. Multiple variable stiffness blades 2 are connected in parallel to a negative pressure compressor. The negative pressure compressor is connected to a vacuum solenoid valve, which controls the negative pressure.

[0019] Furthermore, the main structure of the wind barrier is the support frame 1, which provides stability and support for the entire wind barrier. Above the support frame 1, the movable connection design allows the variable stiffness blades 2 to be adjusted according to changes in wind speed and direction.

[0020] Furthermore, the variable stiffness blade 2 is a key component of the wind barrier, enabling it to achieve variable stiffness in layer blocking. This design allows the wind barrier to automatically adjust its stiffness according to the wind force, thereby improving the protective effect and service life of the wind barrier.

[0021] Furthermore, the variable stiffness blade 2 is internally provided with a waterproof layer 201, an elastic sheet 202, and a filler 203. The waterproof layer 201 can protect the wind barrier from rainwater erosion and improve its service life. The elastic sheet 202 provides good elasticity and resilience, which helps to maintain the shape and stability of the wind barrier. The filler 203 can increase the density and stability of the wind barrier and improve its wind resistance.

[0022] The placement of multifunctional wind barriers depends primarily on their application scenario and required functions. For example, along roads or railways, multifunctional wind barriers are mainly deployed to reduce the impact of strong winds on vehicle operation, improve vehicle stability, and prevent derailment or overturning. In this case, wind barriers are typically arranged continuously along one or both sides of the road or railway line, forming a relatively enclosed wind-reducing zone. Meanwhile, for wind barriers that also need to collect energy, such as multifunctional wind barriers based on triboelectric nanogenerators, their placement may need to consider wind direction, wind speed, and wind energy collection efficiency. Such wind barriers may be designed with structures of specific angles and shapes to more effectively capture wind energy and convert it into electrical energy. In urban environments, multifunctional wind barriers can also be used for noise reduction and sound insulation. In this case, the wind barriers may need to be designed as sound barriers with a certain height and density to effectively block and reduce noise propagation.

[0023] Working principle: This multi-functional wind barrier based on a layered blocking variable stiffness structure has a support frame as the foundation of the entire wind barrier, which bears the weight of the variable stiffness blades and maintains their stability. The movable connection design of the variable stiffness blades allows them to be adjusted to a certain extent as needed to adapt to different wind conditions. The waterproof layer, elastic sheet, filler and other components inside the variable stiffness blades work together to ensure the durability and protective effect of the wind barrier. A waterproof layer prevents water penetration, while elastic sheets provide necessary flexibility and resilience. The filler enhances the wind barrier's stability and wind resistance. The wind barrier consists of multiple layers of variable stiffness units of varying sizes, each adjustable. During wind resistance adjustment, the variable stiffness blades can flap to dissipate energy and reduce drag. These blades resist deformation, resulting in better wind protection. As wind speed increases, the stiffness of the blades increases for stronger protection; conversely, as wind speed decreases, the stiffness decreases to minimize interference with the surrounding environment. The blade stiffness of the wind barrier can be dynamically controlled using a single negative pressure source, thereby controlling its permeability and allowing it to adjust its posture appropriately under different airflow conditions, achieving effective flow control.

[0024] The wind barrier is controlled by a negative pressure source. The negative pressure control system is usually equipped with a pressure sensor to sense the pressure of the gas to be controlled in real time. The sensor converts the pressure signal into an electrical signal and transmits it to the control system. The control system compares the sensed pressure signal with a preset ideal pressure value or range. Based on the result of the comparison, the control system generates a control signal. This control signal is used to adjust the working state of the negative pressure equipment or actuator to achieve the target pressure at the set point. The control signal will be adjusted by the control system or actuator of the negative pressure equipment. The adjusted negative pressure equipment will then perform actual pressure regulation on the system.

[0025] Monitoring sensors play a crucial role in the operation of wind barriers. They can monitor the working status of the wind barrier and surrounding environmental parameters, such as wind speed and direction, in real time. By collecting and analyzing this data, monitoring sensors can provide data support for the intelligent adjustment of the wind barrier. When a change in wind force is detected, the sensor sends a signal to the control system, which then adjusts the stiffness and angle of the variable stiffness blades according to the signal to achieve the best protective effect. The fixing structure and fixing connecting blocks are responsible for firmly fixing the variable stiffness blades to the support frame. Through the cooperation of threaded holes and bolts, the fixing structure ensures the stability of the wind barrier, while the fixing connecting blocks connect the variable stiffness blades and the fixing structure, making them a whole.

[0026] In summary, the working principle of this multifunctional wind barrier based on a layered blocking variable stiffness structure is achieved through the synergistic effect between various components. It utilizes the layered blocking variable stiffness structure to adjust the stiffness of the variable stiffness blades to adapt to different wind conditions. At the same time, components such as waterproof layer, elastic sheet, filler and sealing layer ensure the durability and protective effect of the wind barrier. The monitoring sensor and control system provide intelligent adjustment function, enabling the wind barrier to adaptively adjust according to the actual situation.
