Description

Technical Field

[0001] The invention relates to the technical field of energy-saving buildings, and in particular to a green building energy-saving and emission-reduction ventilation structure. Background Art

[0002] As the global demand for environmental protection and energy conservation continues to increase, the construction industry is facing greater challenges. Traditional building ventilation systems rely on electricity and use mechanical fans, air conditioners and other equipment. Although these devices can provide sufficient air circulation, they usually cause high energy consumption, emission of air pollutants, and are difficult to maintain and have a short service life. Therefore, how to reduce energy consumption and improve ventilation efficiency while ensuring indoor air quality has become an important issue in green building design.

[0003] Common building ventilation equipment on the market include mechanical ventilation systems, natural ventilation systems, and hybrid ventilation systems. Among them, although mechanical ventilation systems can achieve ventilation efficiently, they rely on electricity for energy supply, which increases energy consumption and operating costs. Natural ventilation systems use the natural airflow of buildings to achieve ventilation. Although they are environmentally friendly and energy-saving, they are subject to greater restrictions on climate and environment, and it is often difficult to ensure stable ventilation effects under different weather conditions.

[0004] In this context, new technologies such as turbine wind drive and eccentric motion have gradually attracted attention in the field of building ventilation. These technologies can effectively utilize external natural wind and achieve low-energy and high-efficiency ventilation effects through structural design optimization. For example, the use of vortex effects generated by airflow on the rod surface, high-frequency vibrations generated by wind drive, and the use of bladeless design to enhance wind conversion have achieved initial application and research progress in some fields.

[0005] However, existing building ventilation technology still has the following problems: High energy consumption: Traditional mechanical ventilation systems rely on electricity, resulting in high energy consumption and increased building operating costs.

[0006] Low ventilation efficiency: Some natural ventilation systems are limited by environmental and climatic conditions and cannot maintain efficient operation under different seasons or climatic conditions.

[0007] Complex structure and difficult maintenance: The existing wind-driven system has a complex structure and is difficult to maintain and replace components, resulting in poor long-term stability and economy of the system.

[0008] Pollution problem: Some existing ventilation systems are prone to dust accumulation during long-term operation, affecting air quality, and are often difficult to achieve self-cleaning.

[0009] Therefore, how to design a building ventilation system that can simultaneously meet the requirements of energy saving, environmental protection, efficient ventilation, stable operation and easy maintenance has become a technical problem that needs to be solved urgently. Summary of the invention

[0010] The present invention provides a green building energy-saving and emission-reduction ventilation structure, which aims to achieve energy-saving and environmental protection, high ventilation efficiency and easy maintenance of building ventilation solutions through innovative structural design and pure wind drive mode. The ventilation structure of the present invention includes a ventilation filter box, a driving component, a ventilation duct and a filter refill that can be detachably installed on the inner side of the ventilation filter box.

[0011] The technical solution of the present invention mainly includes the following aspects: The ventilation filter box is one of the core components of the present invention, and a first pump box is provided on its upper surface, and a second pump box is provided on its lower surface. The first pump box and the second pump box are connected to the external airflow channel through the upper cover and the base respectively, so as to realize the input and output of airflow. An air inlet cap is provided on the top of the upper cover for external airflow input, and an exhaust hole is provided on the bottom surface of the base. The exhaust hole is connected to the ventilation duct to transport the compressed airflow into the interior of the building. Through the relative eccentric movement of the movable rotor and the fixed rotor, the present invention realizes the compression and pressurization of the airflow, thereby improving the air circulation effect.

[0012] The driving components include a stand, a vortex sleeve, a swing shaft and a plane shaft seat. The driving components are installed outside the building, such as on the wall or roof. The natural wind force of the airflow generates a vortex effect, which drives the stand to swing rapidly, thereby causing the swing shaft to move eccentrically. The swing shaft is connected to the shaft rod, driving the moving rotor blades and the fixed rotor blades to move relative to each other. This movement is transmitted to the blades inside the ventilation filter box through the eccentric structure of the shaft rod, completing the airflow compression and transportation.

[0013] The moving vanes and the fixed vanes are the key components of the present invention, and the two rotate relative to each other through the eccentric movement of the shaft. Both the moving vanes and the fixed vanes are planar spirals and are located in the same plane. The moving vanes form the working principle of the scroll compressor through the relative movement with the fixed vanes to pressurize the airflow. The cooperation between the moving vanes and the fixed vanes can effectively improve the compression efficiency of the airflow and enhance the overall airflow delivery capacity of the system.

[0014] The ventilation duct is used in conjunction with the filter element to guide the airflow into the building. The filter element is detachable and can effectively filter pollutants in the air to ensure the quality of the air entering the room. The ventilation duct is connected to the exhaust hole on the base to transport the compressed airflow into the building to achieve indoor air circulation and ventilation.

[0015] The beneficial effects achieved by the present invention are: 1. Energy saving and environmental protection, pure wind power drive The present invention adopts pure wind drive, and the natural wind drive system generated by the airflow on the building surface avoids the need for traditional ventilation equipment to rely on energy consumption such as electricity, thereby achieving energy saving. This wind drive method not only conforms to the design concept of green buildings, but also reduces energy consumption, reduces the burden on the environment, and meets the needs of sustainable development.

[0016] 2. Compress the intake air and increase the intake pressure The present invention achieves airflow compression through the relative eccentric movement of the moving rotor and the fixed rotor. This process not only increases the intake pressure, but also avoids the negative impact of structures such as filtering devices on ventilation efficiency. In traditional ventilation systems, filters may produce a certain resistance to airflow, affecting ventilation efficiency, while the design of the present invention can efficiently compress airflow and ensure that airflow passes smoothly through the system, thereby improving overall ventilation efficiency.

[0017] 3. Bladeless structure, using eddy current effect to enhance efficiency The present invention adopts a bladeless vortex sleeve structure, and utilizes the vortex effect generated by the airflow on the rod-shaped surface to generate high-frequency vibrations, driving the vortex sleeve to perform efficient eccentric swings. The application of this vortex effect enables the wind force to be fully utilized and converted into mechanical energy to drive the system, thereby driving the movement of the moving rotor blades. This design not only improves the energy conversion efficiency, but also effectively improves the airflow transmission efficiency. In this way, the present invention can better utilize the external natural airflow and improve the compression and transmission effect of the airflow through eccentric movement.

[0018] 4. Strong adaptability, widely used in different environments The ventilation structure of the present invention can be customized according to different requirements and airflow conditions of the building, and is applicable to a variety of building types and environments. Whether it is an area with strong winds or an area with traditionally weak winds, it can work effectively to ensure the ventilation effect inside the building. The system has strong adaptability and can provide stable ventilation effects according to different climate and environmental conditions.

[0019] Through the above beneficial effects, the present invention not only achieves the energy-saving and emission-reduction goals of the green building ventilation system, but also improves the ventilation efficiency and air circulation effect, and has broad application prospects.

[0022] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0023] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0024] The following is combined with Figure 1-Figure 8 A green building energy-saving and emission-reduction ventilation structure provided by some embodiments of the present invention is described.

[0025] Implementation method 1: basic installation and structural combination The specific implementation of the green building energy-saving and emission-reduction ventilation structure of the present invention is as follows: Installation of driving components: The wind drive assembly 200 is installed on the outdoor wall or roof surface of the building. The external structure of the wind drive assembly 200 is a vortex sleeve 220 of a lightweight composite fiber cylinder structure, which is made of carbon fiber or stripped fiber to ensure that it is light and has sufficient strength. The wind drive assembly 200 adopts the vortex sleeve 220 design, which is connected to the outer periphery of the stand 210. When the wind flows on the surface of the vortex sleeve 220, vortices are generated and the stand 210 is driven to swing rapidly.

[0026] Airflow guiding and compression system: The wind driving component 200 drives the swing shaft 230 to swing eccentrically through the vortex effect. The swing shaft 230 is supported and guided by the plane shaft seat 240 to achieve connection with the shaft 130, driving the shaft 130 to swing eccentrically. The shaft 130 passes through the first pump box 110 and the second pump box 120, and drives the movable rotor 140 and the fixed rotor 150 to produce relative eccentric motion through the first crankshaft 131 and the second crankshaft 132. The movable rotor 140 and the fixed rotor 150 are both planar spirals and are located in the same plane. The rotation of the movable rotor 140 drives the compression and pressurization process of the airflow.

[0027] Function of airflow path and ventilation filter box 100: airflow enters the first pump box 110 through the air inlet cap 112 on the upper cover 111, passes through the interior of the first pump box 110, and flows into the second pump box 120 after being filtered by the filter element 400. In the second pump box 120, the moving vanes 140 and the fixed vanes 150 pressurize the airflow through relative eccentric motion, and finally introduce the compressed airflow into the interior of the building through the ventilation duct 300 through the exhaust hole. The lower cover 121 is connected to the ventilation duct 300 to achieve indoor ventilation and air exchange.

[0028] 2. Implementation Method 2: Optimal Design of Blades and Eccentric Mechanism In another embodiment, the design of the blade structure and the eccentric mechanism is optimized: Moving blades and fixed blades: The movable vane 140 and the fixed vane 150 are both designed in a plane spiral shape, and their outer peripheries are arranged coaxially with the upper cover 111 and the lower cover 121 through the slip ring sleeve 141, ensuring that the airflow can be effectively compressed under their action. Through the eccentric movement of the shaft 130, the relative movement between the movable vane 140 and the fixed vane 150 causes the airflow to be compressed in the space between the two blades, thereby achieving a pressurization effect. In particular, the relative movement between the outer periphery of the movable vane 140 and the slip ring sleeve 141 ensures the high efficiency and stability of the pressurization process.

[0029] Eccentric shaft structure: The eccentric motion driven by the shaft 130 not only drives the relative motion of the moving vane 140 and the fixed vane 150, but also reduces friction and energy loss while ensuring the eccentric effect through the cooperation between the shaft, the sliding plate 133 and other structural parts.

[0030] Eddy current effect and wind power conversion: The wind drive assembly 200 utilizes the wind force generated by the external airflow to guide the airflow to form a vortex through the vortex sleeve 220, which drives the stand 210 to swing, and then converts it into eccentric motion to drive the movement of other components. This structural design ensures that the wind force can be effectively utilized to the greatest extent, and optimizes the working efficiency of the system through the lever principle and eccentric structure.

[0031] 3. Implementation method 3: Adapting to different building environments According to different needs and environments of buildings, the green building energy-saving and emission-reduction ventilation structure of the present invention can provide a variety of adaptive configurations: Flexibility in size and installation: The ventilation system of the present invention can be customized according to the size of the building and the airflow environment, and the size of the ventilation filter box 100, the wind drive assembly 200 and the ventilation duct 300 can be adjusted according to actual needs. The system can be installed in different locations such as the roof, wall or window of the building to adapt to different building types.

[0032] Environmental adaptability: This ventilation structure is suitable for a variety of climatic conditions, especially in areas with strong winds. It can effectively utilize the wind drive system to ensure ventilation effects while saving energy and reducing emissions.

[0033] Summarize Through the above different implementations, the green building energy-saving and emission-reduction ventilation structure of the present invention successfully achieves efficient ventilation inside the building by combining wind drive, eccentric motion and blade pressurization technology. The system's flexible installation method, self-cleaning design and convenient maintenance function give it significant advantages in energy saving and emission reduction, air purification and building ventilation.

[0034] The working principle and use process of the present invention: Working principle: The present invention relates to a green building energy-saving and emission-reduction ventilation structure, which is mainly composed of a wind-driven component 200, a ventilation filter box 100, and a connected ventilation duct 300. Its working principle is based on wind-driven and eccentric swinging structures, and realizes ventilation and air exchange inside the building by converting into airflow compression and delivery.

[0035] The wind-driven assembly 200 is installed on the outdoor wall or roof surface of the building, and utilizes the natural effect of airflow on the building surface. When the airflow flows through the wind-driven assembly 200, the airflow flows on the surface of the columnar vortex sleeve 220, and vortices are generated under the action of wind. This vortex causes the columnar vortex sleeve 220 to swing rapidly.

[0036] Through the guidance of the structures such as the swing shaft 230 and the plane shaft seat 240, the cylindrical vortex sleeve 220 realizes eccentric swing and transmits the swing energy to the output shaft 231. The output shaft 231 is connected to the shaft assembly 130 through a connecting rod, thereby converting the eccentric swing of the swing shaft 230 into the eccentric swing of the shaft assembly 130.

[0037] The eccentric shaft 130 drives the moving vane 140 and the fixed vane 150 to produce relative motion, wherein the fixed vane 150 remains stationary and the moving vane 140 swings near it. The moving vane 140 and the fixed vane 150 are combined into a structure similar to a scroll compressor, and the airflow is compressed through the relative motion of the two blades.

[0038] The compressed airflow enters through the air inlet cap 112 in the ventilation filter box 100 in turn, and is pressurized by the moving vanes and the fixed vanes in the two pump boxes. The pressurized airflow is sent into the interior of the building through the filter element 400 and the ventilation duct 300 to complete the ventilation and air exchange inside the building.

[0039] Usage process: Installation and preparation: Install the wind drive assembly 200 on the roof or exterior wall of the building to ensure that it can receive and utilize ambient airflow. Install the ventilation filter box 100 and its internal structures such as the rotating blades and fixed blades to a suitable position, and connect the ventilation duct 300 to ensure smooth flow of airflow.

[0040] Start-up operation: When the external airflow starts to flow, the wind drive assembly 200 uses the wind force generated by the airflow to activate the vortex, thereby causing the vortex sleeve 220 to swing. The swing is converted into eccentric motion through structural guidance, driving the shaft 130 to generate eccentric swing.

[0041] Airflow compression and delivery: The eccentric motion drives the moving vane 140 and the fixed vane 150 to produce relative motion, forming airflow compression. The compressed airflow passes through the various channels inside the ventilation filter box 100, is further pressurized, and is delivered to the interior of the building through the ventilation duct 300.

[0042] Ventilation and air exchange: The air flow entering the building is further processed to maintain indoor air circulation, remove harmful substances and improve indoor environmental quality.

[0043] Shutdown and maintenance: When the system stops working, regular inspection and maintenance can be carried out to ensure the effectiveness of the ventilation filter box 100 and the filter replacement element 400, and to ensure the stable operation of the wind-driven assembly 200 and the wind-driven structure.

[0044] The present invention realizes the energy-saving and emission-reduction function of green buildings through natural wind power and eccentric swing structure. The wind drive assembly 200 generates vortex through the wind-driven structure, and drives the relative movement between the moving rotor blade 140 and the fixed rotor blade 150 through a series of eccentric movements, ultimately achieving the effect of efficient pressurized air flow delivery, effectively improving the air quality and ventilation effect inside the building.
